Description

Technical Field

[0001] The utility model relates to the technical field of roller screen discharge protection devices, in particular to a roller screen discharge protection device. Background Art

[0002] In the coal, chemical, metallurgy, mining, coking, building materials, raw materials, food and other industries, it is necessary to separate the coarse and fine materials. The roller screen is particularly suitable for the coarse and fine separation in the fuel system of the circulating fluidized bed boiler of the thermal power plant. The circulating fluidized bed boiler burns a certain proportion of coal gangue, and the particle size of the coal in the coal mine is uneven, but most of the materials do not need to be crushed repeatedly, and this part of the material generally accounts for about 35-65% of the whole material. If this part of the qualified particle size material is screened out according to the working conditions, it will bring many benefits to the subsequent working conditions. The roller screen is a machine that uses multi-axis rotation to push the material forward and screen at the same time. The material enters the screen box from the feed port and begins to move downstream at a faster speed under the dual action of its own weight and the rotation of the screen plate while screening. The screen surface of the roller screen is composed of many parallel rollers with screen plates staggered on them. The roller rotates through a sprocket or gear drive, and its rotation direction is the same as the material flow direction. Due to the high speed of the roller shaft, the material falls at a high speed at the tail of the roller screen and is easy to splash. The staff needs to collect and clean the material, which increases the labor intensity of the staff. For example, the Chinese utility model patent with patent number CN216420083U is a roller screen discharge buffer device. Under the set discharge hopper, the large pieces of material falling from the roller screen are effectively buffered by the buffer plate and elastic adjustment component in the flow channel, so as to reduce the impact force of the material when it falls, and ensure the normal operation and avoid damage of the supporting receiving device. At the same time, the elastic adjustment component can be moved horizontally by hinged buffer plate and twisting rotating column, so as to drive the buffer plate to rotate and complete the adjustment of the opening size in the flow channel, so as to adjust and use it when screening different product materials.

[0003] The above device still has certain problems in use. The buffer device needs to be connected to the tail discharge port of the roller screen by a number of bolts, and holes need to be drilled on the roller screen body to fix the buffer device, which causes certain damage to the roller screen body. The installation operation is relatively cumbersome, and it is not convenient to reuse the buffer device. Utility Model Content
