Continuously operating spiral system (COSS) with water cooling by Gronemeyer

Published

on

Continuously Operating Spiral System has always been corresponded with demand in which the products should be sprinkled with cold water and thus cooled faster. Finally, based on our proven COSS with circulating air cooling, we have realized a machine with water cooling. During the construction were not only the hygienic requirements taken into account. Only corrosion-free materials were also used. The drive technology is located outside the enclosure and the sensors are equipped with the highest possible protection.

The double towered COSS stands in a 4 m³ collecting tank. From this reservoir the cooling water is sucked in with a pump, filtered and cooled by a plate heat exchanger. A float switch provides the right amount of water. Via the internal piping the volume flow is evenly distributed in the system over approximated 350 nozzles. During the run the hot products are sprayed with cold water through the nozzles arranged parallel to the chain course.

The enclosure of the machine ensures that no splash water or spray mist penetrates to the outside. It is designed by the combination of VA-sheet and macrolon in such a way that you can look well into the inside of the cooler from the outside.

The number and arrangement of the individual door segments is chosen in such a way that a intervention on all sides of the system is without any tool  possible.

After the wet cooling process the product is dried on the system mat chain by an Airknife. The residual water runs back into circulation.

Coal conveyor application

Published

on

Senkox Technologies Inc. is committed to providing advanced, industry-leading technology to monitor the temperature status of various applications. Coal storage and conveyor systems have a risk of spontaneous combustion, which the Senkox system can help mitigate.

Overview:

Conveyor systems are used to transport coal, granular carbon, and other often combustible materials from one area to another. Conveyor systems use conveyor belts, which are rolls of fabric or rubber pulled by motors along roller bearings to transport the material. These conveyors often run very long distances, requiring a multitude of roller-bearings to move the belt along the track.

Conveyor belts bearings can operate at very high speeds for several hours on end, which can cause ignition from the intense friction of prolonged use. Friction due to the movement of the belt can pose a serious fire risk, especially if the materials being transported are heated or ignited atop the conveyor. Fire typically occurs when dust build-up is unexpectedly ignited by mechanical friction heat. A fire can spread quickly when undisturbed piles overheating material are unknowingly transported through the conveyor system.

Fire outbreak on a conveyor system at a cement plant

If a fire outbreak does occur, the conveyor must be shut down immediately to mitigate the spread the fire throughout the facility. A major concern faced by conveyor systems is the large amount of dense, toxic smoke emitted from the burning belts. This problem can be particularly serious because the thick smoke reduces visibility, and the toxic fumes make breathing difficult. If the conveyor system is located in an underground mine, the toxic smoke is trapped inside and greatly increases the danger for the conveyor workers. The destruction of the manufacturing plant combined with shutting down production ultimately results in substantial monetary loss. With proper fire detection and protection, destruction and tragedy can be greatly minimized.

Approach:

In order to monitor the conveyor systems on the marine vessel, a linear heat monitoring system was needed. Along the roller bearings of the conveyor system, the Senkox HSD™ Linear Heat Sensor solution is monitoring the real-time temperature of the conveyor belts.

The Senkox HSD™ Linear Heat Sensor detects the real-time temperature measurement in order to detect early abnormal temperature conditions and trigger the alarm before the fire becomes a serious disaster. The most effective way to avoid fire and toxic smoke hazards is to install a linear temperature monitoring system along the conveyor belt, as well as other areas of potential fire outbreak such as rollers and motors. This safety system also provides the flexibility to set multi-level alarms to trigger the sprinkler as well a Fault Alarm, which alerts the user if the monitoring system is experiencing a connection problem rather than triggering a false alarm.

Installation Example

Installation:

The Senkox HSD™ Linear Heat Sensors were installed along the conveyor belts of the conveyor system. Should any unusual temperature increase occur, the user will know because Senkox cable monitors the real-time temperature and rate-of-temperature-change (and some sensors also feature the detection of the hot spot’s location and size).

For this installation, eight Senkox Linear heat sensors in total were used to monitor both sides of the conveyor. Having eight individual sensors allowed the end-user to divide the entire monitoring area into eight different zones. Two Senkox DAQ (Data Acquisition) modules were used. Up to four sensors can be connected with one DAQ module, thus by pairing eight sensors with two modules, this installation efficiently maximized Senkox’s technological capabilities.

Each DAQ module was secured 25 meters from the opposing sides of the conveyor system’s monitoring area. The length of the sensor can be adjusted depending on the location or monitoring zone.  A sensor with a maximum length of 200m can be mounted in one zone to monitor the real-time temperature. The sensors connected to the DAQ Module can be the same or different lengths.

Extension cables were also used to connect the sensor away from the DAQ module. Flame retardant zip-ties were used to position the sensor in the desired area near the roller bearings.

Conclusion:

The Senkox HSD™ Linear Heat Sensor allowed the end-user to monitor the conveyor system of any hotspots in real time, and ensured that any rise in temperature would be swiftly addressed. The Senkox HSD™ Linear Heat Detection System is able protect the conveyor belts even in harsh environment of a marine vessel. The user was very satisfied because the low-maintenance safety system can repair any damaged sections of cable without having replace the entire system. The Senkox solution takes long-term maintenance and environmental factors into consideration, but most importantly, the lives of the people traveling onboard the marine vessel.

What is reshoring and why does it matter?

Published

on

The past year and a half have put an enormous strain on supply chains across the globe. Closed borders, reduced production capacity and general global uncertainty in the wake of the corona pandemic has been the main culprit. But recent events in the Suez Canal have also shown the vulnerability in our supply chains, where a seemingly trivial grounding created immediate shortage in western supply of industrial and consumer goods, with companies losing billions of dollars.

To say the least, many companies have started to question the norm of outsourcing production, involving complex and fragile supply chains. Seeing what’s at stake when things go wrong, the economic equation is not as simple as before. Reshoring – to bring production closer to home – has become a hot topic. But what are the advantages and what companies will benefit the most?

Automation and robotization creates opportunities closer to home

There is perhaps an answer to why the discussion of reshoring has taken hold right now. It’s not the first time that supply chains have failed, but it’s the first time when it’s actually a feasible solution to bring production home – to reshore. The solution spells increased automation and robotization of the production process. With increased pressure on decreasing carbon emissions, more and more companies are also looking for ways to be more sustainable. The possibility of reducing transport emissions creates another powerful incentive to bring production closer to home.

At Eton Systems we know the power automation. Our systems help producers across the world to reduce manual labor and increase efficiency in production. This evens out some of the differences between production in high-cost countries and low-cost countries, making reshoring a feasible option. But not yet big enough. We don’t believe there will be a total shift in production, certainly not in the textile business. But we do believe it creates opportunities for companies to diversify and future-proof their companies. Creating a diversified production portfolio, with a mix of production facilities, some closer to home, not only makes for a more secure product supply, it also brings other advantages. According to Norwegian economist Henrik Brynthe Lund, Norwegian companies have benefited from having production facilities closer to home by being able to be more flexible in adjusting production to meet new demands. They can also make continuous tweaks and changes in the product and production process, something which is difficult when the production takes place in on the other side of the world.

We are firm believers in the power of automation and welcome the discussion of reshoring. Every day, we help our customers achieve a more effective production process which decreases lead times and saves manual labor, shifting the focus from handling inefficiencies and production defects. This creates new opportunities to diversify and future-proof the production process, while aiding sustainable solutions and innovation in the process.
