[0026] The working principle of this cooling water pump circulation filter device:

[0027] When in use, the device is installed between the water pipe and the water source. When the water pump is working, the water source is pumped and circulated. During the pumping and circulation, when the water source passes through the middle of the filter box 1, the water source will pass through the middle of the filter cartridge 6 to filter the water source. Because the overall shape of the filter cartridge 6 is cylindrical, the side of the filter cartridge 6 is an arc surface, so that the contact surface between the filter cartridge 6 and the water source is wider. Because the filter surface of the filter cartridge 6 changes from sparse to dense, one side of the filter cartridge 6 will filter larger impurities in the water source, and the other side will filter fine impurities, so that the filter cartridge 6 performs double filtering on the water source, thereby improving the filtering effect. When the filter cartridge 6 needs to be cleaned and replaced, first, by rotating the screw sleeve 204, the screw sleeve 204 moves upward in the middle of the screw rod 203, so that the screw sleeve 204 is separated from the surface of the guide plate 202, because the positioning ring 207 is fixedly installed on the box cover 5 On the lower surface, a positioning ring 207 is arranged inside the positioning groove 205, and a guide plate 202 is slidably installed in the middle of the two guide columns 201, and a screw 203 is fixedly installed on one of the guide plates 202, and one end of the screw 203 movably passes through the other guide plate 202, and a screw sleeve 204 is meshed and connected in the middle of the screw 203, and a plurality of fixing holes 208 are penetrated and opened on the positioning ring 207, and a plurality of fixing columns 206 are equidistantly installed on the front surface of the guide plate 202, and the top of the fixing column 206 is arranged inside the fixing hole 208. At this time, the two guide plates 202 can be moved away from each other in the middle of the two guide columns 201, so that the fixing column 206 can be disengaged from the fixing hole 208, and the positioning ring 207 is not bound in the positioning groove 205. At this time, the positioning ring 207 can be disengaged from the positioning groove 205, so that the box cover 5 can be disengaged from the upper end surface of the filter box 1. At this time, the sealing ring 7 on the upper end of the filter cartridge 6 will be detached from the sealing groove 8 on the lower surface of the box cover 5. At this time, the filter cartridge 6 can be taken out from the filter box 1 and the filter cartridge 6 can be cleaned and replaced. Conversely, the filter cartridge 6 can be installed, which is convenient for the staff to operate.
