[0010] This invention provides a wastewater filtration device for concrete mixing plants. Compared with the prior art, it has the following advantages:

[0011] The wastewater filtration device used in this concrete mixing plant rotates by starting the drive motor, which in turn drives the drive bar to rotate. With the help of the internal gear ring, the entire rotating rod can rotate on its own axis while revolving around the drive bar. This allows the cleaning brush needles to clean the filter holes during rotation, effectively preventing clogging and ensuring normal filtration. It eliminates the need for manual cleaning of the filter holes, resulting in higher cleaning efficiency. Furthermore, the adsorption positioning mechanism facilitates the installation and disassembly of the filter cartridge, making it convenient for future replacement. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution: a wastewater filtration device for a concrete mixing plant, including a wastewater pipe 2 connected to the concrete mixing plant 1, a filter tank 3 fixedly connected to one end of the wastewater pipe 2, the filter tank 3 being fixed to the concrete mixing plant 1 by a support rod 12, a discharge pipe 4 connected to the bottom of the filter tank 3, an insert pipe 5 connected to the discharge pipe 4 fixed inside the filter tank 3, a filter cylinder 6 sleeved on the surface of the insert pipe 5, and multiple filter holes 7 provided on the outer periphery of the filter cylinder 6. The filter holes 7 are used to block impurities such as mud and sand while facilitating water flow. An anti-clogging component 8 is provided on the filter tank 3, which is used to brush the filter holes 7 to prevent the filter holes 7 from becoming blocked. An adsorption positioning mechanism 9 is provided between the filter tank 3 and the filter cylinder 6.

[0020] In this embodiment, the anti-clogging component 8 includes a drive motor 81 fixed above the filter tank 3. The drive motor 81 is electrically connected to an external power source and controlled by a control switch. The output shaft of the drive motor 81 extends into the filter tank 3. A drive bar 82 is fixed to the end of the output shaft of the drive motor 81. A rotating rod 83 rotatably passes through the drive bar 82. A cleaning brush needle 84 is fixed to the surface of the rotating rod 83. The cleaning brush needle 84 can brush and clean the filter holes 7, effectively preventing the filter holes 7 from clogging. An internal gear ring 86 is fixed to the inner wall of the filter tank 3 by a support rod 85. A meshing gear 87 that meshes with the internal gear ring 86 is fixed to the surface of the rotating rod 83. The internal gear ring 86 is a ring gear with teeth on its inner wall. The center of the internal gear ring 86 coincides with the center of the output shaft of the drive motor 81.

[0021] In actual use, water flows into the filter tank 3 through the wastewater pipe 2, and then filters impurities such as mud and sand through the filter cartridge 6. During this process, the drive motor 81 is started, which drives the drive bar 82 to rotate as a whole. With the cooperation of the internal gear ring 86, the entire rotating rod 83 can also rotate on its own axis while revolving with the drive bar 82. This allows the cleaning brush needle 84 to brush and clean the filter holes 7 during rotation, effectively preventing the filter holes 7 from becoming clogged.

[0022] In this embodiment, the adsorption positioning mechanism 9 includes an upper magnetic ring 91 fixed below the filter cartridge 6, and a lower magnetic ring 93 fixed to the inner wall of the filter tank 3 by a vertical rod 92. The upper magnetic ring 91 and the lower magnetic ring 93 work together, with opposite magnetic poles on the sides of the upper magnetic ring 91 and the lower magnetic ring 93 that are close to each other. By utilizing the attraction between the opposite magnetic poles, the filter cartridge 6 can be adsorbed, thus completing the adsorption positioning of the filter cartridge 6.

[0023] In this embodiment, a sealing ring 10 is fixed to the inner wall of the upper magnetic ring 91. The inner wall of the sealing ring 10 is in contact with the surface of the insertion tube 5. The sealing ring 10 helps to improve the sealing performance at the contact point between the insertion tube 5 and the filter cartridge 6.

[0024] In this embodiment, the surface of the filter tank 3 is provided with a discharge port, and the surface of the filter tank 3 is provided with a sealing cover 11 to block the discharge port. The design of the discharge port facilitates the overall discharge of impurities in the later stage. The sealing cover 11 is connected to the filter tank 3 by a hinge. When closed, the sealing performance between the cover and the filter tank 3 is good and there is no leakage. It is also connected to the filter tank 3 by an existing locking structure, which can be locked after closing. When opened, it is convenient to discharge mud and sand impurities. It is also convenient to remove the entire filter cartridge 6 for cleaning, making the operation convenient.
