1.The non-viscous material--ORE
When the plate feeder is running, like dust and some small materials will leak to the bottom of the equipment. If there is a process leak under the foundation of Apron Feeder, the material leaks directly to the ground along the process port. If there is no process leak under Apron Feeder, and Trough Chain Conveyor is designed at the bottom of the Apron Feeder, the above problem can be solved.
2.The viscous material --CLAY
Apron Feeder is running with material, the material runs to the head and falls down, a part of the material is unloaded, and some materials are stuck on the chain plate continue to run. When the clay on the chain plate accumulates to a certain amount, the weight of the chain plate increases. After reaching the tail of the plate feeder, it will be scraped off by the upper bin and accumulate in the tail, which requires manual cleaning. Meanwhile, it will also cause wear of the tail bin and increase the operating resistance. If there is a process lake under the foundation of the plate feeder, the materials are sticky, most of them are not falling, and will be taken to the upper part of the equipment by the running chain plate, so the equipment power will increase, the equipment manufacturing cost increases. If the bottom of the equipment is equipped with Trough Chain Conveyor, when the material accumulates at the bottom and accumulates a certain amount, the scraper belt cannot carry the material, and have resistance to the equipment, the power of the equipment is increased, the design and manufacturing cost are increased, and the overall height of the equipment is increased., some places cannot be arranged.
Previous solutions: The bottom is equipped with high pressure water pipe, washing the chain plate when the equipment is running with materials. Disadvantages: a.There must be a water source on the site, the chain plate is washed with water for a long time, the equipment is easy to rust, the material of the chain plate and the scraper is required, and the cost of
Apron Feeder is increased. b.the head is equipped with a cleaning device. The drawbacks are that the cleaning device purchased in the market is not rigid enough. When the material is sticky, the cleaning beam is bent and deformed. The head is provided with a cleaning device, which is easy to interfere with the running chain plate, and the chain plate is intermittently moved. The cleaning blade is Straight type, when the chain plate breaks down and the scraper is stuck.
The improvement of the bottom cleaner of the plate feeder--Since the material is relatively sticky, at the bottom of the equipment rack, taking into account the direction of the blanking, two rows are added to the V-shaped structure. The bottom of the structure is bolted to the frame, and the upper cutting edge is oriented in the direction of the return of the chain plate. The material attached to the chain plate is scraped off by the friction between the chain plate and the chain plate. The scraped material is smoothly placed on the main conveyor belt below the reserved process port at the bottom of the device. From the design analysis, it reduces the labor intensity of the workers, is more practical and safe, and is simple to manufacture. When designing this scheme, considering some different materials and working conditions, there is a adjustable gap between the upper cutting edge of the cleaner and the returning chain plate.
The Improvement effect--This kind of cleaner, low manufacturing cost, small deformation,reliable motion and convenient maintenance, the blade is welded with wear-resistant hard alloy, improve the service life. The blade edge is inclined 45 degrees, easy to cut clay, the sweeper adopts V-shaped structure, when the material was scraped off, it will move to the center of the device, and the material will not leak. Since each chain plate is a discontinuous plane, in order to avoid the chain plate and the squeegee jam, the squeegee design has a certain oblique angle and has a V-shaped structure. The blade introduction end adopts an arc, and after the smooth transition is introduced, each blade spans three blocks. The above chain plate and the two squeegees are arranged symmetrically, and the lateral forces are mutually offset to avoid the chain biasing, and the squeegee and the frame are bolted to adjust the gap. This improvement is well-designed and simple to manufacture for
Apron Feeder and is currently being widely used.
