The side of the fixed frame 101 close to the water inlet pipe 1 is connected to the water inlet pipe 1, and the side of the fixed frame 101 close to the water outlet pipe 2 is connected to the water outlet pipe 2. The first filter screen 8 is fixedly installed on the side of the fixed frame 101 away from the water inlet pipe 1. A second filter screen 102 is provided on the top of the fixed frame 101. The bottom of the second filter screen 102 passes through the fixed frame 101 and extends to the interior of the fixed frame 101. The second filter screen 102 is movably connected to the fixed frame 101.

[0026] As a technical optimization solution of the present invention, by setting a sealing component 10, the fixed frame 101 is used to connect the filter box 3, the water inlet pipe 1 and the water outlet pipe 2, and the second filter screen 102 can temporarily block impurities entering between the fixed frame 101 and the filter box 3. At this time, impurities inside the filter box 3 can be prevented from passing through the first filter screen 8 into the interior of the water outlet pipe 2.

[0027] refer to Figure 2 The limiting component 11 includes a limiting plate 111 and a through hole 112 . The through hole 112 is opened on the top of the limiting plate 111 . The surface of the limiting plate 111 is fixedly connected to the inner wall of the collecting frame 9 .

[0028] As a technical optimization solution of the present invention, by setting a limiting component 11, the crushed impurities can enter the interior of the collection frame 9 through the through hole 112, and the limiting plate 111 can prevent large-volume impurities that have not been crushed from falling into the interior of the collection frame 9.

[0029] refer to Figure 2 A support frame 12 is provided at the bottom of the filter box 3, the top of the support frame 12 is fixedly connected to the bottom of the fixed frame 101, and a rubber pad 13 is fixedly connected to the bottom of the inner wall of the support frame 12, and the top of the rubber pad 13 fits with the bottom of the collection frame 9.

[0030] As a technical optimization solution of the present invention, by setting a support frame 12 and a rubber pad 13, the support frame 12 can support the fixed frame 101, the filter box 3 and the collection frame 9, and at the same time the rubber pad 13 can provide stable support and shock absorption for the collection frame 9. The support frame 12 and the rubber pad 13 are used to protect the collection frame 9, thereby preventing the collection frame 9 from directly contacting the ground.

[0031] refer to Figure 3 The front and rear sides of the inner wall of the fixed frame 101 are fixedly connected with a sealing strip 14, and a sealing groove 15 is opened on the inner side of the sealing strip 14. The front and rear sides of the surface of the second filter 102 are slidably connected to the inner wall of the sealing groove 15.

[0032] As a technical optimization solution of the present invention, by setting a sealing strip 14 and a sealing groove 15, the sealing strip 14 can seal the gap between the second filter screen 102 and the fixed frame 101, and the sealing groove 15 can improve the sealing effect between the second filter screen 102 and the sealing strip 14.

[0034] As a technical optimization solution of the present invention, by setting a sealing port 16, a sealing plug 17 and a twist plate 18, the sealing plug 17 can be driven to rotate by rotating the twist plate 18, so that the sealing plug 17 can be separated from the sealing port 16. At this time, the broken impurities in the collecting frame 9 and the water entering the collecting frame 9 can flow out together through the sealing port 16.

[0035] refer to Figure 2 A connecting frame 19 is provided inside the collecting frame 9. The surface of the connecting frame 19 is fixedly connected to the inner wall of the collecting frame 9. The connecting frame 19 is located on the top of the limiting plate 111. Openings 20 are opened on the left and right sides of the support frame 12. The surface of the sealing plug 17 is movably connected to the inner wall of the opening 20.

[0036] As a technical optimization solution of the present invention, by providing a connecting frame 19 and a through opening 20, the impurities entering the collecting frame 9 will continue to rotate with the rotation of the crushing rod 5, thereby forming an upward trend from the four sides of the inner wall of the collecting frame 9. At this time, the connecting frame 19 can limit the impurities falling into the collecting frame 9 upward.

[0037] The working principle and use process of the present invention are as follows: when in use, the second filter screen 102 near the side of the water inlet pipe 1 is pulled up, and then water is passed into the interior of the filter box 3 from the water inlet pipe 1, the fixed frame 101 and the water inlet 6 in sequence. At this time, the second filter screen 102 near the side of the water outlet pipe 2 can block the impurities passing through. After using for a period of time, the second filter screen 102 near the side of the water inlet pipe 1 is pressed down. At this time, the two second filter screens 102 play a temporary blocking role for the impurities retained and entering the interior of the filter box 3. Then, the servo motor 4 is started so that the output end of the servo motor 4 drives the crushing rod 5 to rotate to crush the impurities entering the interior of the filter box 3. The crushed impurities can pass through the through hole 11 under the action of gravity. 2 sinks into the collection frame 9. At this time, the connecting frame 19 can limit the impurities that fall into the collection frame 9 upward, thereby preventing the impurities that enter the collection frame 9 from rising again. After the crushing is completed, the servo motor 4 is turned off. After the crushed impurities have finished sinking, the user can drive the sealing plug 17 to rotate by rotating the torsion plate 18, thereby separating the sealing plug 17 from the sealing port 16. At this time, the crushed impurities in the collection frame 9 and the water that enters the collection frame 9 can flow out together through the sealing port 16, thereby completing the collection and cleaning of the crushed impurities. At the same time, the user can clean the impurities attached to the surface of the second filter screen 102 near the side of the water outlet pipe 2 to avoid clogging.

[0038] To sum up: this municipal water supply and drainage filtering device, by setting up a collecting frame 9, the crushed impurities will sink to the inside of the collecting frame 9 under the action of gravity, thereby preventing the crushed impurities from constantly rotating inside the filter box 3 and causing blockage of the first filter screen 8, and solves the problem that when the filter mechanism crushes the impurities, the crushed impurities rotate rapidly around the high-speed rotating crushing knife, and the device does not have an impurity collection structure, which easily causes the crushed impurities to clog the connecting net and the filter frame, affecting use. At the same time, cleaning the connecting net and the filter cover requires the user to repeatedly disassemble the positioning rod, which reduces efficiency.
