Improvement of the Trough Belt Conveyor

The trough conveyer conveys the cooled clinker to the clinker storehouse, the conveying distance is 114m and the hoisting height is 45m. After putting into production, the gear ring of the driving sprocket device (for the whole body in less than one year's running time) Type) serious wear and tear, and the ring gear meshing with the chain, the separation is not good, so that when the device vibration larger; other fixed gear ring bolts frequently loose, often need to stop fastening or replacement. October 2003 Replacement of component ring gear with five equal parts, supplied by equipment supplier, less than 3 months after on-site installation, severe wear on ring gear, frequent bolt looseness. Analyzed, resulting in serious wear and tear ring gear, bolts are often loosened the main reasons: the site installation space is small, poor assembly, resulting in split ring gear force uneven; overload operation; only installed in the tail of the drip tank on the chain Lubrication, ignoring the active gear ring and chain meshing Department of lubrication; environmental dust, chain adhesion dust and more; ring gear operating temperature is high, so that the tension of the bolt is not enough.It's good for the running of trough belt conveyor.

In response to the above situation, we took targeted measures in March 2004: self-mapping, design, production of integral ring gear and prior assembly in the workshop, making a set of active sprocket device and the use of the overall replacement of temporary stop to ensure The ring gear force uniform, so that it meets the assembly requirements; In the active gear ring and chain meshing Department added a lubricating oil pump, according to the operation at regular intervals to start the oil pump will be injected into the ring gear and the gear meshing Department, ensuring that Gear ring and the chain meshing parts of the normal lubrication; the ring gear and the wheel fixed bolts replaced by high strength bolts and heated to 801, make full use of the principle of thermal expansion and contraction, increasing its tension to prevent loosening; in the chain Every 20m made with the old belt slightly smaller than the width of the chain U-shaped clip, fixed in the rack to clean the chain of dust; strengthen kiln system operation, improve clinker cooling effect, and reduce the number of overload equipment.It's good for the running of trough belt conveyor.

After the transformation of the trough conveyor put into operation, running well. Now a ring gear life of 1-12 months, completely changed the original life of less than 3 months and frequent parking fastening or replacement of bolts. The main machine, auxiliary motor original copper ring is replaced with the corresponding form factor of the same iron slip ring, making the ring more wear-resistant which can have a longer life. The original high carbon content carbon brush (brush motor model of the host: J201, size 12.5mmx32mmx50mm, deputy motor motor carbon brush model: J201, specifications for lOmmx25mmx50mm) replaced by the same overall dimensions of copper A high amount of carbon brushes (model number: J164) make the carbon brushes more conductive, withstand higher temperatures and are less susceptible to melting at high temperatures. The use of effect rate is greatly reduced, equipment maintenance costs are greatly reduced. It's good for the running of trough belt conveyor. From June 2006 to complete the transformation so far, the host, deputy motor burn table to reduce to less than 1 units / year. In addition, the service life of the motor slip ring has been greatly improved, from the completion of the transformation to the present 6 cranes host, deputy motor slip ring after more than two years of use of its surface with little wear and tear, and still maintain intact. As the original control host, deputy motor start and stop the exchange of AC contactor replaced with solid-state relay, there is no contact contactor burn out the problem, every month for the purchase of contacts completely saved funds.
