Among them, the water inlet valve 12 is arranged on the water inlet pipe 1, and the water outlet valve 13 is arranged on the water outlet pipe 2. Specifically, second flanges 7 are also arranged at both ends of the first connecting pipe 3, and first flanges 6 are arranged at the connecting ends of the water inlet pipe 1 and the water outlet pipe 2 with the first connecting pipe 3. The first flanges 6 of the water inlet pipe 1 and the water outlet pipe 2 are detachably connected with the second flanges 7 of the corresponding first connecting pipe 3 through bolts. The second flanges 7 at both ends of the first connecting pipe 3 are detachably connected with the water inlet pipe 1 and the water outlet pipe 2 through the first flanges 6, which can facilitate the maintenance and replacement of the purification assembly in the first connecting pipe 3.

[0020] The purification assembly for filtering water quality comprises a backing plate 8 arranged on the first flange 6 of the water outlet pipe 2, a backing ring 9 detachably arranged on the backing plate 8 through bolts, a support 4 arranged on the backing ring 9, and a filter element 5 arranged in the support 4. Among them, the backing plate 8 and the backing ring 9 are connected through bolts, which can facilitate the replacement and maintenance of the filter element 5 in the support 4, and improve the repair efficiency of the water quality purification device for mines. When the purification assembly filters water quality, the water source will flow into the first connecting pipe 3 through the water inlet pipe 1, the water source entering the first connecting pipe 3 will be filtered through the support 4 and the filter element 5, the filtered water source will enter the inside of the filter element 5, and the water source entering the filter element 5 will enter the water outlet pipe 2 and then flow to various equipment for use. After the impurities in the water source and the impurities in the pipeline are filtered by the support 4 and the filter element 5, various impurities can be prevented from entering the working equipment, causing damage to other working equipment. The arrangement of the purification assembly can protect the normal work of other working equipment and effectively improve the service life of other working equipment.

[0021] Among them, the support 4 is preferably an integrated high-strength ultra-thin titanium alloy matrix filter eye integral layout, the eye hole diameter is 2mm, and the inner wall is embedded with a hook (not shown in the figure) which can be used to fix the filter element 5 and improve the stability of the filter element 5 in the support 4.

When the purification assembly in the outer pipe needs to be cleaned, the water inlet valve 12 and the water outlet valve 13 can be closed. At the same time, the communication valve 15 and the blowdown valve 11 are opened, so that the water source enters the second connecting pipe 14, bypasses the outside of the purification assembly, and directly enters the inside of the purification assembly from the other end of the outer pipe. The water source flows out from the outside of the filter element 5 and the support 4 of the purification assembly, and washes the impurities attached to the filter element 5 and the support 4 of the purification assembly. The impurities washed out flow out of the blowdown pipe 10, thereby achieving the purpose of backwashing the purification assembly. The backwashing assembly has the advantages of quick, convenient and high efficiency in cleaning the purification assembly, and has significant economic benefits. When the purification assembly is used to filter impurities in the water source and the pipeline, the blowdown valve 11 and the communication valve 15 need to be closed first, and then the water inlet valve 12 and the water outlet valve 13 are opened.

[0023] As shown in Figure 1 and Figure 2 a pressure gauge 16 is arranged on the outlet pipe 2 between the water outlet valve 13 and the second connecting pipe 14. The water pressure in the outer pipe can be observed through the pressure gauge 16 to understand the filtering condition of the purification assembly in the first connecting pipe 3. The mine water quality purification device has the advantages of simple structure and easy to carry.

[0024] Method for use: when filtering impurities in the water source and the pipeline, the water inlet valve 12 and the water outlet valve 13 are opened, and the blowdown valve 11 and the communication valve 15 are closed. The water source enters the first connecting pipe 3 through the water inlet pipe 1, and then the impurities in the water source and the pipeline are filtered by the purification assembly. The filtered water source flows into each mechanical equipment through the outlet pipe 2. When the purification assembly needs to be cleaned, the water inlet valve 12 and the water outlet valve 13 are closed, and the blowdown valve 11 and the communication valve 15 are opened. The water source in the water inlet pipe 1 enters the communication pipe, and then enters the outlet pipe 2. The outlet pipe 2 is closed by the water outlet valve 13. The water source entering the outlet pipe 2 enters the purification assembly, and then flows out of the purification assembly into the first connecting pipe 3. The water source washes the impurities on the purification assembly into the first connecting pipe 3, and then the impurities in the first connecting pipe 3 flow out through the blowdown pipe 10 to complete the cleaning work of the purification assembly.
