Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a water filtration device. Background Technology

[0002] Wastewater refers to water contaminated by waste or domestic wastewater, containing various harmful substances and bacteria. Therefore, in order to prevent wastewater from polluting the environment, it is necessary to purify the wastewater before discharging it, thereby improving the water quality. During the treatment process, filtration devices are required to filter the wastewater.

[0003] A patent document with publication number CN213221199U discloses a wastewater filtration device, including a treatment unit. The treatment unit has a second sliding groove on its inner wall, and a second sliding block is movably connected to the inner wall of the second sliding groove. A filter plate is fixedly connected to one side of the second sliding block, and a filter screen is fixedly connected to the inner wall of the filter plate. A second limiting groove is formed at the top of the filter plate, and a connecting plate is movably connected to the inner wall of the second limiting groove. A pull ring is fixedly connected to the top of the connecting plate, and a traction rope is movably connected to the outer wall of the pull ring. This wastewater filtration device allows for the movement of the filter screen, facilitating cleaning of its surface. It solves the problem of fixed filter screen structures in general wastewater treatment, making surface cleaning difficult. This provides convenience for workers, reduces their workload, and meets the needs of wastewater treatment.

[0004] The above-mentioned and existing technologies have the following drawbacks: when it is necessary to clean the foreign matter attached to the surface of the filter screen, the filter screen cannot continue to filter the sewage, which can easily reduce the filtration efficiency of the filter screen and make it inconvenient to use the filter screen to filter sewage.

[0005] Therefore, a water filtration device is proposed. Utility Model Content

[0006] The purpose of this invention is to solve the problem that the filter screen cannot continue to filter sewage when it is necessary to clean foreign objects attached to the surface of the filter screen, and to propose a water filtration device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a water filtration device, comprising a filter box, an inlet pipe fixedly connected to the upper surface of the filter box, an outlet pipe fixedly connected to the lower surface of the filter box, a filtration structure provided on the inner wall of the filter box, the filtration structure comprising a ring, the ring being fixedly connected to the filter box, a strip plate fixedly connected to the inner wall of the ring, a motor fixedly connected to the upper surface of the strip plate, a filter plate fixedly connected to the output end of the motor, the filter plate being rotatably connected to the ring, four guide pipes fixedly connected to the side wall of the filter box, the guide pipes being connected to the ring, four auxiliary pipes fixedly connected to the side wall of the filter box, a storage box slidably connected between the guide pipes and the auxiliary pipes, a perforated plate fixedly connected to the inner wall of the storage box, an electric push rod fixedly connected to the side wall of the guide pipe, a sealing plate slidably connected inside the guide pipe, and the output end of the electric push rod being fixedly connected to the sealing plate.

[0008] The effect achieved by the above components is as follows: by setting up a filtration structure, the filter plate can continuously filter the sewage during the sewage filtration process, thereby improving the water quality. When foreign objects in one of the collection boxes are cleaned, the remaining collection boxes can continue to collect foreign objects, so that the filter plate can continuously filter the sewage, thereby preventing the filter plate's filtration efficiency from decreasing due to cleaning foreign objects.

[0009] Preferably, the vertical cross-section of the filter plate is triangular.

[0010] The effect achieved by the above components is that the filter plate with a vertical cross-section in the shape of a triangle allows foreign objects in the sewage to slide down into the circular ring.

[0011] Preferably, a scraper is fixedly connected to the surface of the filter plate, and the scraper is slidably connected to the ring.

[0012] The effect achieved by the above components is that the rotation of the filter plate will cause the scraper to slide along the inner wall of the ring, and the scraper can push the foreign object along the inner wall of the round tube and make the foreign object enter the guide tube.

[0013] Preferably, an isolation cover is fixedly connected to the surface of the strip plate, and the motor is located inside the isolation cover.

[0014] The effect achieved by the above components is that the isolation cover can prevent sewage from causing a short circuit in the motor.

[0015] Preferably, the arc surface of the guide tube is provided with a limiting structure, the limiting structure including a retaining ring, the retaining ring being slidably connected to the guide tube and the storage box, and a roller being rotatably connected between the guide tube and the auxiliary tube, the roller being slidably connected to the storage box.

[0016] The effect achieved by the above components is as follows: by setting a limiting structure, the roller can restrict the movement path of the storage box. When the retaining ring contacts the storage box, the retaining ring and the roller cooperate to restrict the position of the storage box, thereby ensuring that the storage box can collect foreign objects normally.

[0017] Preferably, a spring is fixedly connected to the surface of the retaining ring, and one end of the spring is fixedly connected to the guide tube.

[0018] The effect achieved by the above components is that the spring can prevent the retaining ring from detaching from the storage box.

[0019] Preferably, a round rod is fixedly connected to the surface of the guide tube, and a rotating plate is rotatably connected to the upper end of the round rod.

[0020] The effect achieved by the above components is that when the rotating plate comes into contact with the retaining ring, the rotating plate restricts the position of the retaining ring.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] 1. In this utility model, by setting a filtration structure, the filter plate can continuously filter the sewage during the sewage filtration process, thereby improving the water quality. When foreign objects in one of the collection boxes are cleaned, the remaining collection boxes can continue to collect foreign objects, so that the filter plate can continuously filter the sewage, thereby preventing the filter plate's filtration efficiency from decreasing due to cleaning foreign objects.

[0023] 2. In this utility model, by setting a limiting structure, the roller can restrict the movement path of the storage box.

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0031] like Figures 1-4 As shown, this utility model provides a water filtration device, including a filter box 1, an inlet pipe 2 fixed and connected to the upper surface of the filter box 1, an outlet pipe 3 fixed and connected to the lower surface of the filter box 1, a filter structure 4 provided on the inner wall of the filter box 1, and a limiting structure 5 provided on the arc surface of the guide pipe 405.

[0032] The following section will explain the specific settings and functions of its filter structure 4 and limiting structure 5.

[0033] like Figures 2-4As shown, the filter structure 4 includes a circular ring 401, which is fixedly connected to the filter box 1. A strip plate 402 is fixedly connected to the inner wall of the circular ring 401. A motor 403 is fixedly connected to the upper surface of the strip plate 402. A filter plate 404 is fixedly connected to the output end of the motor 403. The filter plate 404 is rotatably connected to the circular ring 401. Four guide tubes 405 are fixedly connected to the side wall of the filter box 1. The guide tubes 405 are connected to the circular ring 401. Four auxiliary tubes 406 are fixedly connected to the side wall of the filter box 1. A storage box 407 is slidably connected between the guide tubes 405 and the auxiliary tubes 406. A perforated plate 408 is fixedly connected to the inner wall of the storage box 407. An electric push rod 409 is fixedly connected to the side wall of the guide tubes 405. A sealing plate 410 is slidably connected, and the output end of the electric actuator 409 is fixedly connected to the sealing plate 410. The vertical cross-section of the filter plate 404 is triangular. The triangular cross-section of the filter plate 404 allows foreign objects in the sewage to slide down into the ring 401. A scraper 411 is fixedly connected to the surface of the filter plate 404. The scraper 411 is slidably connected to the ring 401. When the filter plate 404 rotates, it will drive the scraper 411 to slide along the inner wall of the ring 401. The scraper 411 can push the foreign objects along the inner wall of the circular tube and allow the foreign objects to enter the guide tube 405. An isolation cover 412 is fixedly connected to the surface of the strip plate 402. The motor 403 is located inside the isolation cover 412. The isolation cover 412 can prevent the sewage from causing a short circuit in the motor 403.

[0034] like Figure 3 As shown, the limiting structure 5 includes a retaining ring 51, which is slidably connected to the guide tube 405 and the storage box 407. A roller 52 is rotatably connected between the guide tube 405 and the auxiliary tube 406. The roller 52 is slidably connected to the storage box 407. A spring 53 is fixedly connected to the surface of the retaining ring 51. One end of the spring 53 is fixedly connected to the guide tube 405. The spring 53 can prevent the retaining ring 51 from disengaging from the storage box 407. A round rod 54 is fixedly connected to the surface of the guide tube 405. A rotating plate 55 is rotatably connected to the upper end of the round rod 54. When the rotating plate 55 contacts the retaining ring 51, the rotating plate 55 achieves the function of limiting the position of the retaining ring 51.

[0035] The overall working principle is as follows: When sewage needs to be filtered, sewage is introduced into the inlet pipe 2, and then the motor 403 is turned on. The rotation of the output end of the motor 403 will drive the filter plate 404 to rotate. When the sewage flows to the surface of the filter plate 404, the filter plate 404 can filter the sewage. At this time, the vertical cross-section of the filter plate 404 can cause foreign objects in the sewage to slide down into the ring 401. At the same time, the rotation of the filter plate 404 can drive the foreign objects to rotate, thereby quickly throwing the foreign objects out. The rotation of the filter plate 404 will drive the scraper 411 to slide along the inner wall of the ring 401. The scraper 411 can push Foreign objects move along the inner wall of the circular tube and enter the guide tube 405. They then fall onto the surface of the perforated plate 408 of the collection box 407, where the collection box 407 collects them. The perforated plate 408 drains the wastewater contained in the foreign objects, improving the space utilization efficiency of the collection box 407. The drained wastewater flows into the filter box 1 through the auxiliary pipe 406. The isolation cover 412 prevents wastewater from causing a short circuit in the motor 403. When it is necessary to clean the foreign objects inside the collection box 407, the output end of the electric actuator 409 retracts, inserting the sealing plate 410 into the guide tube. The guide tube 405 is sealed inside the conduit 405. Then, the retaining ring 51 is lifted upwards. The movement of the retaining ring 51 stretches the spring 53. After the retaining ring 51 disengages from the collection box 407, the rotating plate 55 is rotated. When the rotating plate 55 contacts the retaining ring 51, it restricts the position of the retaining ring 51. Then, the collection box 407 is pulled along the surface of the guide tube 405 and the auxiliary tube 406 to remove it and clean out foreign objects. During this process, the remaining collection box 407 continues to collect foreign objects, and the filter plate 404 continuously filters the wastewater, thus preventing contamination. If foreign objects cause a decrease in the filtration efficiency of the filter plate 404, the cleaned collection box 407 is then placed back between the guide tube 405 and the auxiliary tube 406. The roller 52 restricts the movement path of the collection box 407. When the collection box 407 moves to the appropriate position, the rotating plate 55 is rotated. When the rotating plate 55 disengages from the retaining ring 51, the spring 53 begins to contract. The retaining ring 51 slides downward with the pull of the spring 53 and contacts the collection box 407. The retaining ring 51 restricts the position of the collection box 407, and the spring 53 prevents the retaining ring 51 from disengaging from the collection box 407.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
