Description

Technical Field

[0001] This utility model application relates to the field of filtration device technology, specifically a filtration device for water ecological maintenance. Background Technology

[0002] Aquatic ecosystem conservation refers to a series of measures to protect and restore the health and function of aquatic ecosystems, including controlling water pollution, strengthening water environment monitoring, planting aquatic plants, and constructing ecological floating islands, in order to improve water quality and protect aquatic biodiversity. In order to achieve aquatic ecosystem conservation, polluted water flows will be filtered to remove impurities from the water.

[0003] In existing filtration devices, polluted water is directly discharged into the filter box, filtered by the filter screen, and then discharged directly. However, when the water to be treated contains a lot of impurities, after flowing to the filter screen for a long time during the pretreatment filtration, the impurities filtered out by the filter screen can easily cause blockage, causing the filtration device to lose its filtration efficiency. Summary of the Invention

[0004] To address the problem of filter screens easily becoming clogged during use in existing water ecological maintenance filtration devices, this utility model provides a water ecological maintenance filtration device to solve the aforementioned problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A filtration device for water ecological maintenance includes an inlet pipe and a filter box. A pretreatment pipe is provided between the inlet pipe and the filter box. Both ends of the pretreatment pipe are fixed to the inlet pipe and the filter box respectively through flanges. A drain pipe is fixed through the end of the filter box away from the inlet pipe. A filter screen is detachably fixed at the end of the pretreatment pipe near the inlet pipe. A filter scraper is rotatably sleeved inside the filter screen. The end of the filter scraper that extends to the outside of the filter screen is connected to an impeller. The impeller is installed at the end of the pretreatment pipe near the filter box.

[0007] Furthermore, a sealing ring is fixed to the side of the pretreatment pipe facing the water inlet pipe, a connecting ring is fixed to the outer surface of the filter screen near the end of the water inlet pipe, a support ring is fixed inside the pretreatment pipe on the side of the connecting ring, a fixing ring is fixed inside the water inlet pipe on the side of the connecting ring, and a sealing ring is glued to the side of the fixing ring facing the connecting ring.

[0008] Furthermore, the filter screen is configured as a cone shape with the tip facing the filter box side, the filter scraper is configured as a triangle shape that cooperates with the inner wall of the filter screen, and the outer surface of the filter scraper slides against the inner wall of the filter screen.

[0009] Furthermore, a connecting rod is fixed at the center of the side of the impeller near the water inlet pipe, and an insert is fixed at the end of the connecting rod away from the impeller. A connecting sleeve is fitted on the insert and the connecting sleeve is fixed to the end of the filter scraper that extends to the outside of the filter screen.

[0010] Furthermore, the connecting sleeve has a rectangular groove inside that mates with the insert block, and a support plate is rotatably sleeved on the outer side of the middle part of the connecting rod. Both sides of the support plate are fixed to the inner wall of the pretreatment tube.

[0011] Furthermore, the support ring, fixing ring, and sealing ring are all configured as annular rings that cooperate with the filter screen, and the inside of the water inlet pipe is provided with an annular sealing groove that cooperates with the sealing ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the rotatable scraping structure can remove impurities from the surface of the filter screen in a timely manner during pre-filtration, preventing impurities from adhering to the surface of the filter screen and causing blockage. Moreover, it does not require electric actuation, which solves the problem of filter screens being easily blocked during the use of existing water ecological maintenance filtration devices, and ensures the filtration efficiency of the filtration device.

[0014] 2. In this utility model, the detachable design between the water inlet pipe and the pretreatment pipe allows for timely removal of impurities from the filter screen during use, and also facilitates filter screen replacement, improving the convenience of filter device maintenance and ensuring the sealing of the connection between the water inlet pipe and the pretreatment pipe.

[0020] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Reference Figure 1 , Figure 2 and Figure 3 A filtration device for aquatic ecological conservation includes an inlet pipe 1 and a filter box 3. A pretreatment pipe 2 is installed between the inlet pipe 1 and the filter box 3. Both ends of the pretreatment pipe 2 are fixed to the inlet pipe 1 and the filter box 3 respectively via flanges. A drain pipe 4 is fixed through the end of the filter box 3 away from the inlet pipe 1. A filter screen 5 is detachably fixed to the end of the pretreatment pipe 2 near the inlet pipe 1. The filter screen 5 is cone-shaped with its tip facing the filter box 3. A filter scraper 10 is triangular and fits against the inner wall of the filter screen 5. The outer surface of the filter scraper 10 slides against the inner wall of the filter screen 5. The filter screen 5 has a rotating sleeve inside. The filter scraper 10 extends to the outside of the filter screen 5 and is connected to the impeller 6. A connecting rod 7 is fixed at the center of the side of the impeller 6 near the water inlet pipe 1. An insert block 8 is fixed at the end of the connecting rod 7 away from the impeller 6. A connecting sleeve block 9 is fitted on the insert block 8. The connecting sleeve block 9 is fixed to the end of the filter scraper 10 extending to the outside of the filter screen 5. A rectangular groove that mates with the insert block 8 is opened inside the connecting sleeve block 9. A support plate 11 is rotatably fitted on the outer side of the middle of the connecting rod 7. Both sides of the support plate 11 are fixed to the inner wall of the pretreatment pipe 2. The impeller 6 is installed at the end of the pretreatment pipe 2 near the filter box 3.

[0022] Specifically, when wastewater needs to be filtered, the wastewater is discharged into the pretreatment pipe 2 through the inlet pipe 1. After being filtered by the filter screen 5, it enters the filter box 3 for further filtration. When the water flows to the impeller 6, it drives the impeller 6 to rotate. When the impeller 6 rotates, it drives the connecting rod 7 to rotate. When the connecting rod 7 rotates, the insert block 8 rotates. When the insert block 8 rotates, it drives the connecting sleeve block 9 to rotate, thereby driving the filter scraper 10 to rotate. The rotation of the filter scraper 10 scrapes away the impurities on the inner wall of the filter screen 5, preventing the filter screen 5 from becoming clogged.

[0023] As an optimized solution, a sealing ring 16 is fixed on the side of the pretreatment pipe 2 facing the water inlet pipe 1, a connecting ring 12 is fixed on the outer surface of the filter screen 5 near the end of the water inlet pipe 1, a support ring 13 is fixed inside the pretreatment pipe 2 on the side of the connecting ring 12, a fixing ring 14 is fixed inside the water inlet pipe 1 on the side of the connecting ring 12, and a sealing ring 15 is glued to the side of the fixing ring 14 facing the connecting ring 12. The support ring 13, the fixing ring 14 and the sealing ring 15 are all set as annular rings that cooperate with the filter screen 5, and an annular sealing groove that cooperates with the sealing ring 16 is opened inside the water inlet pipe 1.

[0024] Specifically, when it is necessary to clean the impurities filtered by the filter screen 5, the bolts on the flange are tightened to separate the inlet pipe 1 from the pretreatment pipe 2. When the inlet pipe 1 is separated from the pretreatment pipe 2, the fixing ring 14 and the sealing ring 15 are separated from the connecting ring 12, and the sealing ring 16 is separated from the inlet pipe 1. At this time, the limit received by the connecting ring 12 is released, and the filter screen 5 is pulled to remove it. When it is removed, the connecting sleeve block 9 is separated from the insert block 8. After the filter screen 5 is cleaned or replaced, the treated filter screen 5 is reinserted into the pretreatment pipe 2, so that the connecting sleeve block 9 is fitted onto the insert block 8, and the connecting ring 12 abuts against the support ring 13, fixing the inlet pipe 1 onto the pretreatment pipe 2, and the fixing ring 14 drives the sealing ring 15 to abut against the connecting ring 12. The sealing ring 16 is inserted into the inlet pipe 1. Finally, the inlet pipe 1 and the pretreatment pipe 2 are fixed by the flange and bolts.
