Wedge-shaped telescopic flow guide device for leachate from garbage storage bin

Abstract

The invention discloses a wedge-shaped telescopic flow guide device for leachate from a garbage storage bin. The wedge-shaped telescopic flow guide device for leachate from the garbage storage bin comprises a telescopic transmission assembly, a wedge-shaped cutter head cylinder assembly (2), a poking needle disc assembly (3), a sealing baffle (4), a base (5) and a water spraying system (8). The wedge-shaped cutter head cylinder assembly comprises blades (21), a wedge-shaped flat cylinder (22), a supporting rod (23), flow guide holes (25) and flow guide grooves (26). The wedge-shaped flat cylinder is of a flat cylindrical structure with a rectangular section, and the inner end of the wedge-shaped flat cylinder is an inclined downward wedge-shaped face. The base is arranged in a reserved hole of a bin wall (9). The wedge-shaped flat cylinder and the base are blocked through the sealing baffle. The telescopic transmission assembly drives the wedge-shaped flat cylinder to stretch and retract. The water spraying system sprays water to the flow guide holes and the flow guide grooves. Poking needles (32) of the poking needle disc assembly are inserted into the flow guide grooves. According to the wedge-shaped telescopic flow guide device for leachate from the garbage storage bin, the wedge-shaped flat cylinder stretches and retracts to drive the blades to poke and break garbage such as plastic bags and cloth strips in the storage bin, garbage movement in a local area is caused, blockage is avoided, and it is guaranteed that leachate is smoothly guided out through the flow guide holes and the flow guide grooves.

Description

technical field [0001] The invention relates to equipment used in a domestic garbage treatment plant, in particular to a leachate diversion device of a wedge-shaped telescopic garbage storage bin. Background technique [0002] With the continuous maturity and reliable application of domestic waste incineration power generation technology, domestic and foreign domestic waste incineration power plant (field) models have been actively promoted, and construction projects are increasing. [0003] Garbage storage bins are installed in the pre-treatment section of domestic waste incineration power plants (fields) to receive and store domestic waste transported from abroad. On the side wall of the bottom of the garbage storage bin, usually according to the volume of the garbage pool, one or two rows of fixed grids and other structures are arranged to facilitate the outflow of the garbage leachate. The garbage leachate flows into the leachate pool through the maintenance channel tren...

AI Technical Summary

Problems solved by technology

Judging from the actual operation effect, the grid hole blockage will reappear soon, and the manual operation is very frequent; at the same time, since the fixed grid is at the bottom of the garbage storage bin, the operation is more difficult

Moreover, because the landfill leachate includes the water contained in the waste itself and the high-concentration organic wastewater generated during the waste degradation process, it has the characteristics of complex components, high concentration, large chroma, and strong toxicity. Toxic gas, there is a certain potential safety hazard, so the operator is facing a very harsh environment, and the work intensity is very high

[0004] In addition, due to the consideration of the processing volume of the blocking material, the area of ​​the fixed grid is large, and it is generally made of stainless steel, so the investment cost is very high; at the same time, the large area of ​​the fixed grid also increases the cost of the garbage storage bin wall. Difficulty and expense of handling concrete structures
