[0002] The dust generated during the coal mining process seriously affects and threatens the safe production of coal mines and the health of miners. Some respirable dust can be suspended in the air for dozens of hours under normal circumstances. However, ventilation is required in coal mines to increase the oxygen content in the mine and reduce the content of harmful gases, which further promotes the spread of dust. Usually, a dust suppressant adding device is used to add the dust suppressant to the spray pipeline system in a corresponding proportion to spray the dust.

[0003] The existing dust suppressant adding device has a filtering mechanism at the injection pipe, which easily allows impurities in the feed liquid to enter the spray pipeline system and cause pipeline blockage. Therefore, we propose a dust suppressant adding device for mining and an operating method. Summary of the invention

[0015] Filtering and removing impurities

[0016] Unscrew the sealing cap and inject the liquid into the injection pipe. Filter it through two sets of filter screens to remove internal impurities. The filter screen set at the top filters out larger impurities, and the filter screen set at the bottom filters out fine impurities, which can prevent impurities of different sizes from piling up and affecting the filtering speed.

[0017] Disassembly and cleaning of equipment

[0018] The first installation tube and the second installation tube are pulled vertically upward from the injection tube by pinching the circular plate with fingers. After pulling them out, one hand holds the outer wall of the first installation tube tightly and rotates it so that the first installation tube is located below the second installation tube. At this time, impurities on the filter screen in the first installation tube fall downward due to their own gravity, and then the second installation tube is rotated outward. In this process, the elastic steel sheet is released from the fixing column and the discharge port of the second installation tube will deviate from the position of the first installation tube, thereby causing the impurities on the filter screen in the second installation tube to fall. Then, the two groups of circular plates are pinched respectively and force is applied downward to separate the two groups of filter screens from the first installation tube and the second installation tube respectively. At this time, clean water can be used to clean each component.

[0021] 2. The installation through-tube is plugged into the injection tube and the two sets of filters are fixed in the inner cavity of the installation through-tube by the cooperation of elastic magnetic strips and support rings. The installation through-tube can be moved out of the injection tube and the filter screen can be separated from the installation through-tube by pinching the circular plate with fingers, which is convenient for disassembly and cleaning of the filters.
