Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] The following is a further detailed description of this application in conjunction with the attached Figures 1-5 This application will be further described in detail.

[0024] This application embodiment discloses a water supply and drainage filtering device. Refer to Figures 1 to 4 , a water supply and drainage filtering device, including a water inlet pipe 1, and a filtering mechanism 2 is arranged at one end of the water inlet pipe 1;

[0025] The filtering mechanism 2 includes a connecting pipe 201, the inner wall of the connecting pipe 201 is threadedly connected with a sealing cover 202, the number of the sealing covers 202 is two, a motor 203 is fixedly installed on one side of one of the sealing covers 202, the output end of the motor 203 is fixedly installed with a screw rod 204, the screw rod 204 penetrates into the inner cavity of the connecting pipe 201, a rotating groove 205 is opened on the inner wall of the sealing cover 202, the inner cavity of the rotating groove 205 is movably connected with a filter screen 206, the number of the filter screens 206 is two, one end of the water inlet pipe 1 penetrates into the inner side of one of the filter screens 206 and is fixedly communicated with the inner wall of the connecting pipe 201, the surface of the screw rod 204 is in contact with the inner side of the filter screen 206, and the bottom of the connecting pipe 201 is fixedly communicated with a discharge pipe 3.

[0026] Refer to Figure 1 , an observation hole 4 is opened on the surface of the connecting pipe 201, and plexiglass is inlaid on the inner wall of the observation hole 4. By setting the observation hole 4, the accumulation amount of impurities can be monitored in real time through the observation hole 4. When the impurities reach the preset threshold, rotate the sealing cover 202 on the left side of the connecting pipe 201 to open the end of the connecting pipe 201, and quickly remove the accumulated impurities;

[0027] Refer to Figure 3 and Figure 4, an arc-shaped block 5 is fixedly installed on one side of the filter screen 206, and a sealing gasket 6 is fixedly installed on the inner wall of the rotating groove 205. By setting the arc-shaped block 5, both ends of the filter screen 206 can be in a flat state. The arc-shaped block 5 enters the inner cavity of the rotating groove 205, so as to realize the support of the sealing cover 202 for the filter screen 206, which can increase the sealing performance at the connection between the filter screen 206 and the sealing cover 202 and prevent the overflow of unfiltered water;

[0028] Refer to Figure 2 , a docking block 7 is fixedly installed on the inner side of one of the filter screens 206, and a slider 8 is fixedly installed on the inner side of the other filter screen 206. The surface of the slider 8 is slidably connected to the inner side of the docking block 7. Through the sliding connection between the docking block 7 and the slider 8, it is convenient to dock the two filter screens 206 to form a cylinder, so that the connection between the two filter screens 206 is in a closed state and prevent the overflow of unfiltered water;

[0029] Refer to Figure 2 and Figure 3 , two partition plates 9 are fixedly installed on the inner wall of the connecting pipe 201. The inner sides of the partition plates 9 are in contact with the surface of the filter screen 206. By setting the partition plates 9, the bottom of the filter screen 206 can be supported, thereby increasing the stability of the filter screen 206 during operation. Holes are provided at the bottom of the partition plates 9 to prevent water from remaining in the inner cavity of the connecting pipe 201;

[0030] Refer to Figure 1 , a fixing plate 10 is fixedly installed at the bottom of the motor 203, and the fixing plate 10 is fixedly connected to the side of the sealing cover 202 opposite thereto. By setting the fixing plate 10, the position of the motor 203 can be fixed, thereby increasing the stability of the motor 203 during operation;

[0031] Refer to Figure 1 , a flange 11 is fixedly installed at the top of the water inlet pipe 1, and a sealing ring 12 is fixedly installed inside the flange 11. By setting the flange 11, the sealing performance of the connection between the water inlet pipe 1 and the drainage pipe can be increased, and the sealing performance between the two is further increased by the sealing ring 12.

[0032] Working principle: The water inlet pipe 1 is docked with the drainage pipe through the flange 11. After the docking is completed, the drain pipe discharges the unfiltered water into the inner cavity of the water inlet pipe 1. The water in the inner cavity of the water inlet pipe 1 will not come into contact with the connecting pipe 201 immediately. Through the guidance of the water inlet pipe 1, the water can be pre-entered into the space formed by the two filter meshes 206 to achieve the purpose of filtering the water. At the same time, the water filtered by the filter mesh 206 will be in the inner cavity of the connecting pipe 201. A valve is provided on the surface of the discharge pipe 3, and the valve controls the opening and closing of the discharge pipe 3. By opening the discharge pipe 3 through the valve, the filtered water can be discharged to complete the filtering work. During the process of water entering the space formed by the two filter meshes 206, the motor 203 is started through an external power supply, and the screw rod 204 is driven to rotate by the motor 203. During the process of the filter mesh 206 filtering the water, the filter mesh 206 is semi-circular, which can make the impurities stay on the inner side of the filter mesh 206. Through the rotation of the screw rod 204, the impurities can be moved in one direction, so that the impurities are accumulated at one end of the connecting pipe 201, thereby realizing the centralized collection of the impurities. The collection degree of the impurities is observed through the observation hole 4. When the impurities are accumulated to a certain extent, the sealing cover 202 is rotated to open one end of the connecting pipe 201, so as to facilitate the removal of the impurities from the cavity formed by the two filter meshes 206, complete the centralized collection of the impurities, and facilitate the treatment of the impurities. When the passing rate of the filter mesh 206 does not meet the use requirements, the sealing covers 202 at both ends of the connecting pipe 201 are opened simultaneously, the motor 203 and the screw rod 204 can be removed, and at the same time, the filter mesh 206 at the lower part is pre-slid and removed. The filter mesh 206 at the upper part can move downward, and the filter mesh 206 at the upper part can be removed and replaced. Through the fixation of the position of the filter mesh 206 by the sealing cover 202, it is convenient for the user to remove and replace the filter mesh 206, reducing the replacement time.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
