The working principle and the using process of the invention are as follows: when the new inner filter screen 501 and the new inner filter screen 501 are overlapped in pore space and the filtering diameter is the largest, the tachometer motor 605 is started, the tachometer motor 605 drives the screw rod 602 to rotate, the two screw rod nuts 603 move on the circumferential surface of the screw rod 602, the two support rods 604 push the push plate 606 to move downwards, the water flow tachometer 601 moves downwards along with the push plate 606, the water flow tachometer 601 is started to set the flow velocity in the inner filter screen 501 and the outer filter screen 502, the water flow tachometer 601 transmits data to the PLC controller 4 for storage, after the inner filter screen 501 and the outer filter screen 502 are used for a period of time, the tachometer motor 605 is restarted to drive the water flow tachometer 601 to move downwards to measure the water flow velocity in the inner filter screen 501 and the outer filter screen 502, the PLC controller 4 sends a signal to the indicator lamp when receiving the flow velocity transmitted by the water flow tachometer 601 and being lower than a certain value, the indicator lamp sets up a flash to send a signal to the outside, reminding a user to replace the inner filter screen 501 and the outer filter screen 502, after the connecting flange 3 and the mounting flange 2 are separated, pressing the T-shaped push rod 506, the T-shaped push rod 506 pushing the spring block 509 to return to the spring groove 507, the reset spring 511 and the clamping spring 508 being in a compressed state, pulling the outer filter screen 502, the outer filter screen 502 driving the clamping block 504 to leave the clamping groove, the reset spring 511 and the clamping spring 508 returning to the original position due to self elasticity, at this time, the outer filter screen 502 and the inner filter screen 501 are separated from the connecting flange 3, the inner filter screen 501 and the outer filter screen 502 are replaced in the same way, adjusting the rotation of the motor 503, the inner filter screen 501 rotating along with the outer filter screen 502, because the outer filter screen 502 is not moved, the overlapped part of the inner filter screen 501 and the outer filter screen 502 is smaller and smaller, thereby impurities with different sizes can be filtered, the device can remind the user to replace the inner filter screen 501 and the outer filter screen 502 through the indicator lamp, meanwhile, the outer filter screen 502 and the connecting flange 3 can be separated only by pressing the T-shaped push rod 506, a user can replace the inner filter screen 501 and the adjusting motor 503 conveniently, and meanwhile, the inner filter screen 501 and the outer filter screen 502 are matched with each other to enable the Y-shaped filter to filter impurities with different diameters.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
