Description

Technical Field

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

[0002] Domestic sewage is complex in composition, containing not only a large amount of bulky waste such as discarded beverage bottles, waste packaging paper, waste paper towels, and unintercepted kitchen waste, but also a large amount of large-particle solid debris and some floating matter. Before treating and purifying domestic sewage, it is necessary to conduct preliminary filtration to remove large-particle solid debris and some floating matter, so as to facilitate subsequent purification treatment. However, the existing domestic sewage treatment devices are prone to clogging of the filter screen and are not easy to clean quickly. To solve the above problems, a filtration device for water treatment is needed.

[0003] Existing water treatment filtration equipment has a cumbersome process for disassembling and assembling the filter screen during operation. Debris easily accumulates at the outlet of the sewage pipe, making it difficult to clean quickly. Debris also easily accumulates on the surface of the filter screen, causing the filter screen pores to become clogged. This leads to a sudden increase in pressure inside the sewage pipe, which may cause leaks at pipe connections or even pipe rupture. The overflow of sewage not only pollutes the surrounding environment but also increases maintenance costs and downtime. Therefore, there is an urgent need for a new water treatment filtration device. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a water treatment filtration device to solve the problems of the cumbersome disassembly and assembly process of existing water treatment filtration devices, the easy accumulation of debris at the outlet of the sewage pipe, the difficulty in quick cleaning, the easy accumulation of debris on the surface of the filter screen, causing the filter screen mesh to become clogged, which leads to a sudden increase in pressure in the sewage pipe, which may cause leakage at the pipe connection or even pipe rupture. The overflow of sewage not only pollutes the surrounding environment, but also increases maintenance costs and downtime.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water treatment filtration device, including a sewage pipe, a fixing sleeve installed on the outer wall of the sewage pipe, a positioning rod penetrating the interior of the fixing sleeve, a positioning sleeve installed on the outer wall of the positioning rod, positioning blocks installed on both sides of the outer wall of the fixing sleeve, a connecting rod installed on the inner wall of the positioning block, a fixed shaft penetrating the interior of the connecting rod, a filter sleeve installed on the outer wall of the connecting rod, a limit rod installed on the inner wall of the filter sleeve, a guide plate installed on the outer wall of the limit rod, and a scraper installed on the outer wall of the guide plate.

[0006] Preferably, the fixing sleeve is sleeved with the sewage pipe, and the positioning rod passes through the inside of the fixing sleeve and the sewage pipe and is threadedly connected to the positioning sleeve.

[0007] Preferably, the positioning block is symmetrically arranged around the central axis of the fixed sleeve, and the positioning block is movably connected to the connecting rod.

[0008] Preferably, the fixed shaft passes through the interior of the connecting rod and is threadedly connected to the positioning block, and the filter sleeve is sleeved with the fixed sleeve.

[0009] Preferably, the limiting rod is movably connected to the filter sleeve, and the end of the guide plate is spirally arranged.

[0010] Preferably, the scraper is symmetrically arranged with the central axis of the limiting rod as the center, and the scraper is in close contact with the inner surface of the filter sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model uses a sewage pipe, a fixed sleeve, a positioning rod, a positioning block, a connecting rod, a fixed shaft, and a filter sleeve. The fixed sleeve is connected to the sewage pipe, and then the positioning rod and positioning sleeve are used for flange fixation, which is convenient for disassembly and assembly. Then the filter sleeve is connected to the fixed sleeve, and the fixed shaft passes through the inside of the connecting rod and is threaded to the positioning block. The filter sleeve can initially filter and intercept the sewage discharged from the sewage pipe. When the surface of the filter sleeve or the outlet of the sewage pipe accumulates debris, the fixed shaft is rotated in the opposite direction to release the locking state, and then the filter sleeve is pulled outward to clean the pipe opening or the inner surface of the filter sleeve. The operation is simple, the cleaning is efficient, and the practicality is enhanced.

[0013] This utility model, through the setting of a limiting rod, a guide plate, and a scraper, allows the internal water flow to drive the guide plate to rotate when sewage flows out of the drain pipe. At the same time, it drives the scraper to scrape the inner surface of the filter sleeve, preventing debris from clogging the mesh of the filter sleeve and achieving a self-cleaning function for the inner surface of the filter sleeve. Meanwhile, the guide plate is driven by the water flow, eliminating the need for a motor and making it more environmentally friendly and energy-saving. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] Please see Figures 1-4 A water treatment filtration device includes a drain pipe 1, a fixed sleeve 2 installed on the outer wall of the drain pipe 1, a positioning rod 3 penetrating the interior of the fixed sleeve 2, a positioning sleeve 4 installed on the outer wall of the positioning rod 3, positioning blocks 5 installed on both sides of the outer wall of the fixed sleeve 2, a connecting rod 6 installed on the inner wall of the positioning blocks 5, a fixed shaft 7 penetrating the interior of the connecting rod 6, and a filter sleeve 8 installed on the outer wall of the connecting rod 6. The fixed sleeve 2 is sleeved with the drain pipe 1, and the positioning rod 3 penetrates the interior of the fixed sleeve 2 and the drain pipe 1 and is threadedly connected to the positioning sleeve 4. The positioning blocks 5 are symmetrically arranged around the central axis of the fixed sleeve 2, and the positioning blocks 5 are movably connected to the connecting rod 6. The fixed shaft 7 penetrates the interior of the connecting rod 6 and is threadedly connected to the positioning blocks 5. The filter sleeve 8 is sleeved with the fixed sleeve 2. The system consists of a sewage pipe 1, a fixing sleeve 2, a positioning rod 3, a positioning sleeve 4, a positioning block 5, a connecting rod 6, a fixing shaft 7, and a filter sleeve 8. The fixing sleeve 2 is fitted onto the sewage pipe 1, and then the positioning rod 3 and the positioning sleeve 4 are used for flange fixation, which facilitates disassembly and assembly. The filter sleeve 8 is then fitted onto the fixing sleeve 2, and the fixing shaft 7 passes through the inside of the connecting rod 6 and is threadedly connected to the positioning block 5. The filter sleeve 8 can initially filter and intercept the sewage discharged from the sewage pipe 1. When debris accumulates on the surface of the filter sleeve 8 or at the outlet of the sewage pipe 1, the fixing shaft 7 is rotated in the opposite direction to release the locking state, and then the filter sleeve 8 is pulled outward to clean the pipe opening or the inner surface of the filter sleeve 8. The operation is simple, the cleaning is efficient, and the practicality is enhanced.

[0022] Please see Figures 1-4A water treatment filtration device includes a filter sleeve 8 with a limiting rod 9 installed on its inner wall, a guide plate 10 installed on the outer wall of the limiting rod 9, and a scraper 11 installed on the outer wall of the guide plate 10. The limiting rod 9 is movably connected to the filter sleeve 8. The end of the guide plate 10 is spirally arranged, and the scraper 11 is symmetrically arranged around the central axis of the limiting rod 9. The scraper 11 is in close contact with the inner surface of the filter sleeve 8. Through the limiting rod 9, the guide plate 10, and the scraper 11, when sewage flows out of the drain pipe 1, the internal water flow will drive the guide plate 10 to rotate, and at the same time drive the scraper 11 to scrape the inner surface of the filter sleeve 8, preventing debris from clogging the mesh of the filter sleeve 8 and realizing the self-cleaning function of the inner surface of the filter sleeve 8. At the same time, the guide plate 10 is driven by the water flow, eliminating the need for a motor drive, making it more environmentally friendly and energy-saving.

[0023] Working principle: In use, first, connect the fixing sleeve 2 to the sewage pipe 1, and then fix it with the flange using the positioning rod 3 and positioning sleeve 4 for easy disassembly and assembly. Then, connect the filter sleeve 8 to the fixing sleeve 2, and connect it to the positioning block 5 by threading through the fixing shaft 7 through the inside of the connecting rod 6. The filter sleeve 8 can perform preliminary filtration and interception of sewage discharged from the sewage pipe 1. When debris accumulates on the surface of the filter sleeve 8 or at the outlet of the sewage pipe 1, rotate the fixing shaft 7 in the opposite direction to release the locking state, and then pull the filter sleeve 8 outward to filter the sewage at the pipe opening or on the inner surface of the filter sleeve 8. The cleaning process is simple, efficient, and highly practical. When the sewage flows out of the drain pipe 1, the internal water flow will drive the guide plate 10 to rotate, and at the same time drive the scraper 11 to scrape the inner surface of the filter sleeve 8, preventing debris from clogging the mesh of the filter sleeve 8 and realizing the self-cleaning function of the inner surface of the filter sleeve 8. Meanwhile, the guide plate 10 is driven by the water flow, which does not require motor drive, making it more environmentally friendly and energy-saving. This completes the use of the device.
