[0002] In order to reduce the escape of coal dust underground, most mechanical operation equipment is equipped with a spray dust reduction device. The end of the spray dust reduction device mostly uses atomizing nozzles. The water quality underground is poor, and the atomizing nozzles are easily blocked when directly sprayed with underground water. In order to prevent the atomizing nozzles from being blocked and ensure the normal operation of the device, the underground water needs to be filtered through a filter before entering the atomizing nozzles.

[0003] After retrieval, a dust reduction spray device with reverse cleaning of a filter, with the publication number CN214233017U, includes: a cleaning and filtering module, the cleaning and filtering module is arranged on the dust reduction spray device, and the cleaning and filtering module includes: a filter, valve A and valve B. The filter is provided with a liquid inlet pipe, a liquid outlet pipe and a sewage discharge pipe. Valve A is arranged on the liquid outlet pipe, and valve B is arranged on the sewage discharge pipe; the filter includes: a housing and a filter element; a closed space is arranged inside the housing, the upper part of the housing is communicated with the liquid inlet pipe, the lower end of the housing is communicated with the sewage discharge pipe, a filter element is arranged inside the housing, the liquid outlet pipe penetrates through the housing wall and is communicated with the filter element, and the liquid inside the housing enters the liquid outlet pipe through the filter element.

[0004] However, when using the above device, it is inconvenient to install the connecting pipe. The installation position of the dust reduction spray device underground is generally high. When disassembling and assembling the connecting pipe, it is necessary to continuously provide a supporting force for the connecting pipe, increasing the work burden. Therefore, it is necessary to provide a dust reduction spray device with reverse cleaning of a filter, which can facilitate the disassembly and assembly of the connecting pipe. Content of the Utility Model

[0005] The purpose of the utility model is to provide a dust reduction spray device with reverse cleaning of a filter to solve the problem raised in the above background technique, that is, when using the above device, it is inconvenient to install the connecting pipe.
