[0008] Further, the first grid is provided with a combination groove at a position opposite to the second grid, and the second grid is arranged in the combination groove of the first grid.
[0009] The utility model discloses a self-made wind and water pipe backwash filter device, which has the following advantages: when supplying coal mining work through the wind and water pipe, the first pipe valve and the second pipe valve are opened, and the third pipe valve and the fourth pipe valve are closed. At this time, the wind and water flow direction in the wind and water pipe is from the first pipe valve through the filter device to the second pipe valve, the filter device is used to filter impurities in the water passing through the wind and water pipe, and the composite filter is used to filter out the impurities. When the composite filter in the filter device is clogged with impurities, resulting in insufficient wind and water pressure, affecting the normal progress of various works, and when the filter device and the composite filter need to be cleaned, the first pipe valve and the second pipe valve are closed, the third pipe valve and the fourth pipe valve are opened, and the wind and water flow direction is to flow from the front of the closed first pipe valve into the backwash pipe to form a backwash flow. The backwash flow reaches between the filter device and the second pipe valve, enters the filter device due to the closed state of the second pipe valve, and is then discharged through the impurity discharge pipe. When the backwash flow passes through the filter device, it will flush the composite filter screen, flush the impurities filtered by the composite filter screen, and discharge them from the impurity discharge pipe with the backwash flow. The filter device and the composite filter are cleaned to achieve cleaning of the clogged filter device and the composite filter; when the main line is supplying normal wind and water, the wind and water flow pushes the inner filter of the composite filter in the filter device to slide on the outer filter, so that the second grille of the inner filter enters the combined groove of the first grille of the outer filter, and the first grille and the second grille with different directions are combined to form a dense filter to filter impurities in the wind and water flow passing through. When the composite filter is clogged with impurities, resulting in insufficient wind and water pressure, affecting the normal progress of various operations, a backwash flow is introduced into the filter device through the backwash pipeline for flushing. The backwash flow is opposite to the direction of the wind and water flow for normal wind and water supply, pushing the inner filter of the composite filter in the filter device to slide in the outer filter, so that the first grille is separated from the combined groove, forming a separation of the first grille and the second grille, so that the originally dense filter is divided into two grilles with larger gaps, which is convenient for cleaning and removing impurities on the composite filter, and preventing impurities from clogging the composite filter, resulting in insufficient wind and water pressure when wind and water are supplied, affecting the normal progress of various operations.
