Novel underground coal mine water filter provided with adjustable filter boards, and filtering method

Abstract

The invention discloses a novel underground coal mine water filter provided with adjustable filter boards, and a filtering method. The novel underground coal mine water filter comprises a filter housing, an explosion-proof electric machine, a bevel gear transmission mechanism, a filter raw water input, a backwashing water outlet, a filtered water outlet and a support. Characteristics are that: an upper movable filter plate, a lower movable filter plate, a fixed filter board, a filter board elevating mechanism, a guiding device and filter materials are arranged in the filter housing; a screen mesh with a pore size less than the partical size of the filter materials is welded on the upper surface of the upper movable filter board; the lower movable filter board is a filter board with a larger pore size; a filter cap is arranged on the fixed filter board; the filter materials are placed between the upper movable filter board and the fixed filter board; the filter raw water inlet is connected to a water deliver pump; the backwashing water outlet is connected to a sewage tank; and the filter board elevating mechanism is driven by the explosion-proof electric machine through the bevel gear transmission mechanism, so that the movable filter boards are capable of realizing reciprocating movement upwards and downwards. Advantages are that: backwashing effects are excellent, filter material loss in backwashing is avoided effectively, and the novel underground coal mine water filter is capable of realizing automatic backwashing.

Description

technical field [0001] The invention relates to a water filtering device, in particular to a novel coal mine underground water filter with an adjustable filter plate and a filtering method. Background technique [0002] Coal mine underground water filters are limited by special conditions such as water flow, filtration accuracy and working space, and many special requirements are put forward for filter equipment. Usually coal mines use uniform coarse filtration equipment, and configure precision filters in front of each specific water use equipment. Although this can meet the use requirements, it will invisibly increase maintenance and management costs. For example, in traditional filtration equipment, if the lifting rod adjustment motor is placed vertically on the top of the filter, the equipment will be too high; although the traditional fiber ball filter material filter can meet the filtration requirements, it is difficult to backwash, and long-term use will cause the equ...

AI Technical Summary

Problems solved by technology

Usually coal mines use uniform coarse filtration equipment, and configure precision filters in front of each specific water use equipment. Although this can meet the requirements of use, it will increase maintenance and management costs virtually.

For example, in traditional filtration equipment, if the lifting rod adjustment motor is placed vertically on the top of the filter, the equipment will be too high; although the traditional fiber ball filter material filter can meet the filtration requirements, it is difficult to backwash, and long-term use will cause the equipment to fail to operate normally. , the filter material needs to be replaced frequently; these factors lead to the inability of the filter equipment to operate stably for a long time in the special working environment of the coal mine

In addition, the current filter has backwashing running out of material and uneven washing of the filter material, which seriously affects the backwashing effect
