Coal Roller Screen Cleaning Device Assembly Depth Analysis Structure Composition Cleaning Mechanism And Maintenance Optimization Practice
Coal roller screen is a kind of heavy screening equipment which is composed of multiple spiral blades and distributed at the bottom of the screen frame. It is widely used in coal, ore, garbage and other materials. Coal roller screen is also called “Wobbler feeder” And “Disc screen” Its transmission structure can be directly connected to the motor reducer screen shaft, or through the chain to use more, or the use of gear reducer and other three driving forms of organization. It has the advantages of large processing capacity, not easy to plug and so on.
The coal roller screen is responsible for the removal of the “Three large blocks” (coal, wood and stone, iron blocks have been mostly removed by the iron remover) in the raw coal burned by the boiler. The roller screen in wet coal or long time operation, the screen shaft will be attached to a large number of coal, resulting in reduced screen shaft clearance, fine coal can not be separated, most of the coal into the crusher, causing the crusher overload, blockage and other series of chain reactions, in the unit load is more make the production extremely passive.
Roller sieve smooth or not directly affects the raw coal supply of the unit, due to the influence of coal quality, the viscosity of coal is particularly large, the roller sieve is used for one or two hours, the roller screen will be blocked, the roller sieve often occurs jam, many times the wet coal blocking screen caused by the coal crusher explosion hydraulic coupling and jumping accident, according to statistics, once a class up to 36 jumping machine. The hydraulic coupler exploded twice, which caused great damage to the coal transport system. Due to the blocking of the screen, the flow area of the screen parting surface is seriously reduced, whether it is large or broken coal is sent to the coal crusher, resulting in the coal crusher load seriously exceeding the standard and the explosion of the hydraulic coupling or the belt jump, which is particularly damaging to the coal crusher and the belt joint. In order to ensure the normal supply of coal to the unit, special personnel are organized to dig every day, which is a large workload and unsafe.
A coal roller screen cleaning device assembly comprises a roller screen, the roller screen is provided with a roller screen teeth, the roller screen outside the roller screen guard is provided with a support beam, the support beam axis and the axis of the roller screen parallel to each other, the support beam is provided with a triangular comb tooth perpendicular to the axis of the support beam: The surface of the support beam provided with triangular comb teeth is provided with a circular arc groove concave to the inside of the entity; the surface corresponding to the surface of the support beam with triangular comb teeth is provided with a circular arc groove concave to the inside of the entity.
Coal roller screen cleaning device assembly, add comb teeth to the screen plate to clean the screen plate to ensure that the coal sticking between the screen plate is not blocked, the rotation of the roller itself will be scraped off the coal sticking between the screen plate to remove, strengthen the support of the comb plate, and strengthen the three directions with three reinforcement plates at both ends. To ensure that it will not be deformed when a lot of debris is entangled, the structure is simple, the installation is convenient, the labor intensity of workers is reduced, the work efficiency is improved, and the personal safety of workers is guaranteed.
Our company is a professional crushing and screening and bulk material conveying equipment supplier, our supply of special folding screening equipment coal roller screen is specially developed for material blockage and a screening equipment, its unique design structure and processing technology to ensure that it will not lead to material blockage. The separate operation of multiple sieve shafts can greatly improve the screening efficiency, and avoid the damage of one sieve shaft resulting in the shutdown of the whole equipment.
