Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a buried integrated wastewater treatment device. Background Technology

[0002] Integrated wastewater treatment equipment is suitable for water sources with small volumes and relatively stable water quality. Generally, domestic wastewater treatment processes can be divided into two types: biofilm process and activated sludge process. The advantage of buried integrated wastewater treatment equipment is that it does not require building construction, heating, or insulation, and is typically buried underground.

[0003] Current underground sewage treatment equipment suffers from numerous pits and dents due to the underground pipes, making the pipe walls susceptible to corrosion. This also makes it easier for dirt to adhere to the pipe walls, which is difficult to clean. As the amount of dirt accumulates, it eventually causes pipe blockage. In existing technologies, manual cleaning and maintenance are generally required periodically. Therefore, this invention proposes an underground integrated sewage treatment device that can automatically clean the dirt adhering to the pipe walls, reducing the difficulty of manual cleaning and slowing down the corrosion of the pipes. Summary of the Invention

[0004] To address the technical problem of difficulty in cleaning existing pipe attachments, this invention proposes an underground integrated sewage treatment device.

[0005] This invention proposes an underground integrated sewage treatment device, comprising an outer casing, a reaction tank for sewage purification installed inside the outer casing, a connecting pipe installed on one side of the reaction tank for introducing sewage into the reaction tank, and an inlet pipe located on the outside of the outer casing and communicating with the connecting pipe. An inlet for installing the inlet pipe is provided on the side of the outer casing near the connecting pipe. A rectangular hollow plate is installed inside the inlet pipe. Multiple evenly distributed movable openings are provided on the outer walls of the hollow plate. Each movable opening contains a scraper with an arc-shaped outer surface, sloping upwards from the inside out, for scraping off deposits adhering to the wall of the inlet pipe. Both sides of the top of the plate are fixed with L-shaped first hanging rods. Both sides of the inner wall of the inlet pipe are fixed with lugs that support the first hanging rods from below. The lugs are equipped with positioning posts. The first hanging rods have round holes into which the positioning posts can be inserted. The positioning posts are fitted with first springs at both ends, which abut against the first hanging rods and the lugs respectively. When sewage flows into the inlet pipe, the sewage flow force creates a downward impact on the hollow plate. The hollow plate and the scraper move downward as a whole, squeezing the first springs. When the sewage stops flowing in, the reverse elastic force of the first spring pushes the hollow plate and the scraper to move upward to reset. When the scraper moves up and down, it scrapes off the deposits on the wall of the inlet pipe.

[0006] Preferably, both ends of the positioning post are provided with external threads, the top of the ear block is provided with a threaded hole that forms a threaded connection with the bottom end of the positioning post, and the top of the positioning post is threadedly connected with a first nut that restricts the first hanging rod from sliding out of the top of the positioning post.

[0007] Preferably, a central rod is provided inside the hollow plate, and multiple first connecting rods, which are evenly distributed vertically and vertically, and whose outer ends are rotatably connected to the scraper, are rotatably connected to the outer walls of the central rod. The central rod and the hollow plate are jointly provided with a mechanism to reset the central rod.

[0008] Preferably, the mechanism for resetting the center rod includes a second hanging rod fixed on both sides of the center rod, a second spring fixed at the bottom of the outer end of the second hanging rod, and a sliding groove formed with the center rod on both sides of the hollow plate inner wall, with the bottom end of the second spring abutting against the bottom inner wall of the sliding groove.

[0009] Preferably, the top of the central rod is fixed with an umbrella-shaped force-bearing plate whose outer diameter is smaller than the inner diameter of the hollow plate.

[0010] Preferably, the edge of the load-bearing plate is provided with an integrally formed upward-curving edge.

[0011] Preferably, the inner walls on both sides of the movable opening are provided with integrally formed limiting posts, and the scraper is provided with limiting grooves on both sides, which are open at the inner end and closed at the outer end and have a sliding fit with the limiting posts.

[0012] Preferably, both sides of the inner surface of the scraper are provided with baffles to prevent the adhesion from leaking out.

[0013] Preferably, a collection box for collecting pipe wall deposits is inserted at the bottom end of the hollow plate, the bottom of which is densely covered with drainage holes. L-shaped ear plates are fixed on both sides of the bottom of the collection box, and bolts are inserted on the ear plates. Threaded grooves that form a threaded connection with the bolts are opened on both sides of the hollow plate.

[0014] Preferably, both ends of the hollow plate are provided with circular openings located above the collection box, and the same main shaft is inserted into the two circular openings. A sealing plate is fitted on the main shaft, and the top of the sealing plate is rotatably connected to a second connecting rod whose top end is rotatably connected to the central rod. Both ends of the main shaft are threaded with a second nut for restricting the movement of the main shaft within the circular openings.

[0015] Compared with the prior art, the present invention provides a buried integrated sewage treatment equipment, which has the following beneficial effects:

[0016] 1. A buried integrated sewage treatment equipment, wherein when the equipment is started to treat sewage, the sewage flow force impacts the hollow plate downward when the sewage flows into the inlet pipe, and the hollow plate and scraper move downward as a whole, squeezing the first spring. When the equipment stops and the sewage stops flowing in, the reverse elastic force of the first spring pushes the hollow plate and scraper to move upward to reset. When the scraper moves up and down as described above, it scrapes off the deposits on the wall of the inlet pipe, thereby achieving the effect of removing the deposits on the pipe wall, preventing pipe blockage, and reducing the degree of pipe corrosion. At the same time, the outwardly extending scraper can intercept flocculent matter in the sewage, preventing flocculent matter from clogging the pipe.

[0017] 2. An underground integrated sewage treatment device, wherein the first hanging rod is stabilized on the positioning column by the first nut. During installation, the positioning column is first tightened into the threaded hole, then the first spring is put into the positioning column, then the round hole on the first hanging rod is aligned with the positioning column and inserted, and finally the first nut is tightened to the top of the positioning column, so as to achieve the effect of easy disassembly and assembly.

[0018] 3. A buried integrated sewage treatment device, wherein the impact force of sewage acts on the central rod, which generates a downward pulling force on the first connecting rod and the scraper, thereby pulling the scraper into the movable opening, causing the scraper to disengage from the inlet pipe wall. When the central rod moves downward, it simultaneously drives the second hanging rod to move downward along the slide groove. The second hanging rod compresses the second spring, and the hollow plate as a whole is also in a downward state. This prevents the scraper from scraping off the attached objects when sewage continuously flows into the inlet pipe. When the sewage stops entering, the elastic force of the second spring pushes the central rod downward. The upward reset movement allows the scraper end to contact the pipe wall. As the hollow plate moves upward, the scraper lifts up the pipe wall deposits, which then slide down the scraper and enter the hollow plate through the movable port. This facilitates subsequent collection of the pipe wall deposits, preventing them from flowing into the reaction tank with the sewage and increasing the workload of the reaction tank. During installation, simply insert the second hanging rod into the slide groove, and the bottom end of the second spring will press against the bottom wall of the slide groove. Then, fix the inner end of the second hanging rod to the central rod. This makes disassembly and assembly convenient and easy to remove for cleaning.

[0019] 4. An underground integrated sewage treatment equipment, which increases the area of ​​sewage impact through a force-bearing plate, thereby enabling the central rod to move downward quickly. The umbrella-shaped structure can guide the sewage outwards after impact, allowing the sewage to flow smoothly downwards. The raised edges can increase the resistance to sewage when impacted, thereby ensuring the impact effect.

[0020] 5. An underground integrated sewage treatment equipment, which uses the cooperation of a limiting groove and a limiting column to stably limit the movement of the scraper. The inner end of the limiting groove is open and the outer end is closed, so that when installing the scraper, the inner end of the limiting groove is inserted into the limiting column, thereby facilitating the installation and removal of the scraper.

[0021] 6. A buried integrated sewage treatment device, in which pipe wall deposits are collected in a collection box, and water is filtered out by the densely distributed drainage holes. The collection box can be removed by unscrewing the bolts from the threaded groove, making it convenient to clean the collected pipe wall deposits. When the central rod moves downward, the sealing plate is rotated to a horizontal position through the second connecting rod, thereby sealing the top of the collection box and effectively preventing sewage from directly rushing into the collection box and carrying away the collected pipe wall deposits. When the central rod moves upward to reset, the sealing plate rotates to an inclined position, at which time the pipe wall deposits scraped up by the scraper can enter the collection box.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Example

[0036] Reference Figure 1-11An underground integrated sewage treatment device includes an outer casing 1, a reaction tank 12 for sewage purification installed inside the outer casing 1, a connecting pipe 13 installed on one side of the reaction tank 12 for introducing sewage into the reaction tank 12, and an inlet pipe 3 located on the outside of the outer casing 1 and communicating with the connecting pipe 13. An inlet 2 for installing the inlet pipe 3 is provided on the side of the outer casing 1 near the connecting pipe 13. A rectangular hollow plate 4 is installed inside the inlet pipe 3. Multiple evenly distributed movable openings 5 ​​are provided on the outer walls of the hollow plate 4. Scrapers 6, with an arc-shaped outer surface and inclined upwards from the inside out, are provided in the movable openings 5 ​​for scraping off deposits on the wall of the inlet pipe 3. L-shaped first hanging rods 7 are fixed on both sides of the top of the hollow plate 4. Lugs 8 supporting the first hanging rods 7 are fixed on the inner walls of both sides of the inlet pipe 3. A positioning post 9 is provided on the first hanging rod 7, and a round hole 11 is provided on the first hanging rod 7 into which the positioning post 9 can be inserted. The positioning post 9 is fitted with a first spring 10 at both ends, which abuts against the first hanging rod 7 and the ear block 8 respectively. When the equipment starts to treat sewage, when sewage flows into the inlet pipe 3, the sewage flow force forms a downward impact on the hollow plate 4. The hollow plate 4 and the scraper 6 move downward as a whole, squeezing the first spring 10. When the equipment stops and the sewage stops flowing in, the reverse elastic force of the first spring 10 pushes the hollow plate 4 and the scraper 6 to move upward and reset as a whole. When the scraper 6 moves up and down as described above, it will scrape off the deposits on the pipe wall of the inlet pipe 3, thereby achieving the effect of removing the deposits on the pipe wall, preventing pipe blockage, and reducing the degree of pipe corrosion. At the same time, the outwardly extending scraper 6 can intercept the flocculent matter in the sewage, preventing the flocculent matter from clogging the pipe.

[0037] Furthermore, both ends of the positioning post 9 are provided with external threads 15, and the top of the ear block 8 is provided with a threaded hole 14 that forms a threaded connection with the bottom end of the positioning post 9. The top of the positioning post 9 is threaded with a first nut 16 that restricts the first hanging rod 7 from sliding out of the top of the positioning post 9. The first nut 16 stabilizes the first hanging rod 7 on the positioning post 9. During installation, the positioning post 9 is first tightened into the threaded hole 14, then the first spring 10 is put into the positioning post 9, then the round hole 11 on the first hanging rod 7 is aligned with the positioning post 9 and inserted, and finally the first nut 16 is tightened to the top of the positioning post 9, achieving the effect of easy disassembly and assembly.

[0038] Furthermore, a central rod 17 is provided inside the hollow plate 4. Multiple first connecting rods 18, evenly distributed vertically, are rotatably connected to the outer walls of the central rod 17, their outer ends rotatably connected to the scraper 6. A mechanism for resetting the central rod 17 is provided on both the central rod 17 and the hollow plate 4. The impact force of the sewage acts on the central rod 17, generating a downward pulling force on the first connecting rods 18 and the scraper 6, thereby pulling the scraper 6 into the movable opening 5. This causes the scraper 6 to disengage from the wall of the inlet pipe 3, and simultaneously, the hollow plate 4 as a whole moves downwards. While sewage continuously flows into the inlet pipe 3, the scraper 6 is prevented from scraping off the deposits. When the sewage stops flowing in, the mechanism that resets the center rod 17 drives the center rod 17 to move upward, so that the end of the scraper 6 contacts the pipe wall. During the upward movement of the hollow plate 4, the scraper 6 scrapes up the deposits on the pipe wall, and the deposits then slide down the scraper 6 and enter the interior of the hollow plate 4 through the movable port 5, so that the deposits on the pipe wall can be collected later, thus preventing the deposits on the pipe wall from flowing into the reaction tank 12 with the sewage and increasing the workload of the reaction tank 12.

[0039] Furthermore, the mechanism for resetting the center rod 17 includes second hanging rods 19 fixed on both sides of the center rod 17. A second spring 21 is fixed to the bottom of the outer end of the second hanging rod 19. The inner walls on both sides of the hollow plate 4 are provided with sliding grooves 20 that form a sliding fit with the center rod 17. The bottom end of the second spring 21 abuts against the bottom inner wall of the sliding groove 20. When the center rod 17 moves downward, it simultaneously drives the second hanging rod 19 to move downward along the sliding groove 20. The second hanging rod 19 squeezes the second spring 21. Finally, the elastic force of the second spring 21 pushes the center rod 17 to move upward to reset. During installation, it is only necessary to insert the second hanging rod 19 into the sliding groove 20. The bottom end of the second spring 21 will abut against the bottom wall of the sliding groove 20. Then, the inner end of the second hanging rod 19 is fixed to the center rod 17. It is easy to disassemble and clean.

[0040] Furthermore, an umbrella-shaped force-bearing plate 22 with an outer diameter smaller than the inner diameter of the hollow plate 4 is fixed to the top of the central rod 17. The force-bearing plate 22 can increase the area of ​​sewage impact, thereby allowing the central rod 17 to move downward quickly. The umbrella-shaped structure can guide the sewage outward after impact, allowing the sewage to flow down smoothly.

[0041] Furthermore, the edge of the load-bearing plate 22 is provided with an integrally formed upward-curving edge 23. The upward-curving edge 23 can increase the resistance to sewage when subjected to sewage impact, thereby ensuring the impact effect.

[0042] Furthermore, the inner walls on both sides of the movable port 5 are provided with integrally formed limiting posts 25, and the scraper 6 is provided with limiting grooves 24 on both sides, which are open at the inner end and closed at the outer end and form a sliding fit with the limiting posts 25. The scraper 6 can be stably limited and moved by the cooperation of the limiting grooves 24 and the limiting posts 25. The limiting grooves 24 are open at the inner end and closed at the outer end, so when installing the scraper 6, the inner end of the limiting grooves 24 can be inserted into the limiting posts 25, which facilitates the installation and removal of the scraper 6.

[0043] Furthermore, both sides of the inner surface of the scraper 6 are provided with baffles 35 to prevent the side leakage of the deposits, which can prevent the deposits on the pipe wall from being exposed from the side when they slide down the scraper 6.

[0044] Furthermore, a collection box 26 with numerous drainage holes is inserted into the bottom of the hollow plate 4 to collect the pipe wall deposits. L-shaped ear plates 27 are fixed on both sides of the bottom of the collection box 26, and bolts 29 are inserted into the ear plates 27. Threaded grooves 28 are opened on both sides of the hollow plate 4 to form a threaded connection with the bolts 29. The pipe wall deposits enter the collection box 26 for collection, and the numerous drainage holes can filter out the water. The collection box 26 can be removed by unscrewing the bolts 29 from the threaded grooves 28, thus facilitating the cleaning of the collected pipe wall deposits.

[0045] Furthermore, both ends of the hollow plate 4 are provided with circular openings 33 located above the collection box 26. The same main shaft 30 is inserted into the two circular openings 33. A sealing plate 31 is fitted on the main shaft 30. The top of the sealing plate 31 is rotatably connected to a second connecting rod 32, which is rotatably connected to the top of the central rod 17. Both ends of the main shaft 30 are threaded with a second nut 34 to restrict the movement of the main shaft 30 within the circular openings 33. When the central rod 17 moves downward, the sealing plate 31 is rotated to a horizontal state through the second connecting rod 32, thereby sealing the top of the collection box 26 and effectively preventing sewage from directly entering the collection box 26 and carrying away the collected pipe wall deposits. When the central rod 17 moves upward to reset, the sealing plate 31 rotates to an inclined state, at which time the pipe wall deposits scraped up by the scraper 6 can enter the collection box 26.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
