Hydraulic automatic dredger for leachate filtering holes

Abstract

The invention discloses a hydraulic automatic dredger for leachate filtering holes, and is suitable for solving the problem that a filter screen is blocked in a process of draining leachate of a garbage power plant. The hydraulic automatic dredger for the leachate filtering holes comprises a rack, a reciprocating linear driving mechanism and a dredging executing mechanism, wherein the rack is mounted on a wall of a garbage pool; the dredging executing mechanism comprises an elastic connector and a plurality of pins mounted on the elastic connector; the pins are in one-to-one correspondence to the filtering holes of a leachate filtering screen; the elastic connector is driven by power of the reciprocating linear driving mechanism to linearly move towards the leachate filtering screen until the various pins are inserted into the corresponding filtering holes, and at the moment, elasticity of the elastic connector can be stored; and when power driving of the reciprocating linear driving mechanism is withdrawn, the pins is pushed by the stored elasticity of the elastic connector to be reset. A pure manual construction mode in a current garbage power plant filtering screen dredging process can be eliminated, the mechanism is simple, degree of automation is high, and dredging efficiency and construction safety are improved.

Description

technical field [0001] The invention relates to the technical field of garbage power plant equipment, in particular to a hydraulic automatic dredging machine for leachate and filtrate holes. Background technique [0002] In waste-to-energy plants, it is necessary to concentrate production and domestic waste in the waste pool first. Since there is a lot of leachate in the waste, in order to increase the calorific value of waste-to-energy, these leachate must be removed. A leachate channel is opened at the bottom of the pool, that is, a window is opened on the side wall near the bottom of the pool, and a leachate filter is arranged on the window. The leachate is filtered through the filter and enters the sewer in the leachate channel, and is discharged into the leachate collection Pool, and then concentrated pump out. Therefore, the liquid flow of the filtrate holes of the filter screen plays an important role in the discharge of leachate. [0003] The leachate filter screen...

Problems solved by technology

[0004] The existing dredging method mainly uses manual dredging and cleaning of the filter screen. The main disadvantages of this dredging method are: first, the dredging quality is not high, and second, there are many dredging windows, a large amount of manual work, and a large labor intensity , and because there are a large amount of dangerous and harmful gases in the leachate channel, there are certain safety hazards
