[0029] like Figure 1 , 2As shown in Figure 4, an overflow pipe Ⅰ43 is also provided on the filter box Ⅰ4. The overflow pipe Ⅰ43 is arranged at an upper position of the filter box Ⅰ4, and the overflow pipe Ⅰ43 is closer to the upper end of the filter box Ⅰ4 than the connecting pipe 2. When the water inlet amount of the water inlet pipe 1 and the water outlet amount of the connecting pipe 2 do not match, and the water inlet amount is greater than the water outlet amount, there is more cooling water in the filter box Ⅰ4, and the cooling water gradually approaches the upper end of the filter box Ⅰ4. At this time, the cooling water flows out from the overflow pipe Ⅰ43. The overflow pipe Ⅰ43 can prevent the cooling water from overflowing. A sewage pipe Ⅰ44 is provided on the filter box Ⅰ4. The sewage pipe Ⅰ44 is arranged at a lower position of the filter box Ⅰ4. After the filtration of the cooling water is completed, the sewage pipe Ⅰ44 can be opened to discharge the cooling water in the filter box Ⅰ4.

[0030] like Figure 1-6 As shown, the upper end of the filter box Ⅰ4 is provided with a plurality of grooves, the grooves include a through groove 41 and a connecting groove 42, the through groove 41 penetrates the upper end of the filter box Ⅰ4 to the inside, the connecting groove 42 is provided at the upper end of the filter box Ⅰ4 and is connected with the through groove 41, a support plate 51 is fixedly provided at one end of the filter net Ⅰ5, a handle 52 is provided at one end of the support plate 51, the filter net Ⅰ5 is slidably provided in the through groove 41, and the support plate 51 is connected to the connecting groove 42. When installing, the filter net Ⅰ5 is inserted into the through groove 41, and the support plate 51 is supported on the connecting groove 42. When taking it out, hold the handle 52 Lift up the filter screen Ⅰ5 and the support plate 51. A threaded hole Ⅰ421 is provided on the connecting groove 42, and a threaded hole Ⅱ53 is provided on the support plate 51. The threaded hole Ⅰ421 and the threaded hole Ⅱ53 are aligned. Bolts 54 are detachably connected in the threaded holes Ⅰ421 and Ⅱ53 to fix the support plate 51 and the filter box Ⅰ4. A sealing ring 422 is also provided on the inner wall of the connecting groove 42. The support plate 51 and the filter box Ⅰ4 are connected. The sealing ring 422 is sleeved on the outside of the support plate 51, which greatly ensures the sealing performance of the device and prevents cooling water from flowing out from the upper end.

[0031] like Figure 1 , 2 As shown, the filter box Ⅱ6 is also provided with an overflow pipe Ⅱ62 and a drain pipe Ⅱ63. The overflow pipe Ⅱ62 has the same structure as the overflow pipe Ⅰ43 and is also arranged at the upper position of the filter box Ⅱ6 to prevent the cooling water in the filter box Ⅱ6 from flowing back from the connecting pipe 2. The drain pipe Ⅱ63 is arranged at the lower position of the filter box Ⅱ6. After the filtering of the cooling water is completed, the drain pipe Ⅱ63 can be opened to discharge the cooling water in the filter box Ⅱ6. The water outlet pipe 3 is provided with a pump body 31 for pumping out the filtered cooling water in the filter box Ⅱ6.

[0032] As shown in the figure, since a large amount of cooling water is required in the production process, there will be more impurities inside the impurity removal device after long-term use. The impurity removal device cannot be shut down for a long time to clean it. Only one of the filter boxes can be cleaned, and the other filter box works normally. An emergency pipe 7 is arranged between the water inlet pipe 1 and the filter box Ⅱ6. At the same time, valve bodies 71 are respectively arranged on the emergency pipe 7 and the water inlet pipe 1 to control the flow direction of cooling water. When the filter box Ⅰ4 is being cleaned, the valve body 71 on the water inlet pipe 1 is controlled to be closed and the valve body 71 on the emergency pipe 7 is opened. The cooling water enters the filter box Ⅱ6 from the emergency pipe 7 for normal filtration. When the filter box Ⅱ6 is cleaned, the connecting pipe 2 is directly removed and connected to other mechanical sealing equipment.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
