Description
Technical Field
[0001] The utility model relates to the technical field of solid waste screening, in particular to a screening device for solid waste pretreatment. Background Art
[0002] Solid waste can be roughly divided into three categories according to its source: domestic waste, general industrial solid waste and hazardous waste. In addition, there are agricultural solid waste, construction waste and spoil. If solid waste is not properly collected, utilized and disposed of, it will pollute the atmosphere, water bodies and soil and endanger human health.
[0003] During the use of the existing screening device for solid waste pretreatment, it mainly has the problem that it does not have the function of collecting the sediment and dust remaining in the solid waste, resulting in sediment and dust being all over the place after screening, which is not convenient for centralized cleaning. Secondly, the existing screening device for solid waste pretreatment also has the problem that it does not have the function of pulling out the screening cylinder for cleaning during use. As a result, after a period of use, the notch of the screening cylinder is extremely easy to be blocked, which makes the screening effect not ideal and reduces the screening efficiency.

And a pull ring is arranged at the outer end of the baffle 13. Through the setting of the pull ring, when it is necessary to separate the dust collection bottom cylinder 7 and the bracket 8, the clamping block 12 can be pulled outward through the pull ring, so that the clamping block 12 squeezes the spring 11 on the inner wall of the round block 10 to deform and contract, and thus gradually disengages from the clamping grooves 9 opened on the outer edges of the dust collection bottom cylinder 7 and the bracket 8. At this time, the restriction between the dust collection bottom cylinder 7 and the bracket 8 is cancelled, and thus the dust collection bottom cylinder 7 and the bracket 8 can be separated, which is convenient for cleaning the dust in the dust collection bottom cylinder 7. Secondly, by using the fixed connection between the lapping roller 3 and the U-shaped plate 4, combined with the sliding connection between the U-shaped plate 4 and the inner wall of the outer cylinder 1, and then using the sliding connection between the lapping roller 3 and the lapping groove 2, when the lapping roller 3 is pulled upward on the inner wall of the lapping groove 2, the lapping roller 3 can drive the U-shaped plate 4 to slide upward together, so as to facilitate taking out the screening cylinder 5 from the inner wall of the outer cylinder 1, achieving the purpose of cleaning the screening cylinder 5.
