Automatic dredging system for sump

Abstract

The invention discloses an automatic dredging system for a sump. The automatic dredging system comprises a mud scraper, a submersible sewage pump, a vibrating screen and a filter press, wherein the mud scraper is arranged in the sump, and the submersible sewage pump is arranged at a place for storing mud scraped by the mud scraper, and is connected with the vibrating screen through a pipeline; and an outlet of the vibrating screen is connected with the filter press. The automatic dredging system provided by the invention has the advantages of high sludge handling ability, relatively thorough cleaning of paste-like sludge, high level of mechanization, high working efficiency and low labor intensity; and the real-time dredging is beneficial to mine safety production, the recycling of coal slime is favorable for improving the economy efficiency of a mine, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to a desilting equipment, in particular to an automatic desilting system for a water tank. Background technique [0002] The water tank is an indispensable part of the mine drainage system. It has two main functions: one is to store water, and the other is to settle. The mine water contains impurities mainly coal slime and sand, which settle down after entering the water tank. The sediment in the water tank needs to be cleared and dug out in time, otherwise the effective volume of the water tank will be reduced. When encountering sudden water gushing, the water in the water tank will overflow and cause the risk of flooding at the bottom of the well; when the sediment accumulates too much For a long time, debris will enter the suction well and then be sucked into the water pump, which will aggravate the wear and tear of the flow-passing parts of the water pump; when there is too much silt in the suction well, the suction faucet wi...

Problems solved by technology

The disadvantages are: 1. It is necessary to build a ground sewage treatment system; 2. The pulsating impact generated when the plunger pump is working seriously damages the drainage pipeline system; 3. It is easy to cause blockage of the main drainage pipe, which will cause scale to hang on the inner wall of the pipeline and reduce drainage efficiency

[0007] The above methods generally have the following problems: the paste sludge is not cleaned thoroughly, the moisture content in the sludge is large, and it is easy to pollute the environment

This method can be used in mines with a small amount of slime and frequent cleaning, but for large mines with a large amount of slime, the processing capacity of the filter press cannot meet the requirements, and the filter press generally can only process particle sizes <0.5 mm's sundries
