Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an integrated rural wastewater treatment device. Background Technology

[0002] With the comprehensive advancement of the rural revitalization strategy and the significant improvement of rural living standards, the discharge of rural domestic sewage is showing an increasing trend year by year, thus requiring integrated sewage treatment devices.

[0003] In the process of sewage treatment, sewage treatment equipment needs to use auxiliary pipelines and equipment such as return pumps, return pipes, and aeration pipes to achieve sludge return, aeration and other operations. Therefore, existing biofilm sewage treatment equipment requires auxiliary pipelines to be configured outside the entire equipment. These external pipelines are not conducive to the transportation of integrated sewage treatment equipment, and also increase the space occupied by the sewage treatment equipment.

[0004] The existing patent (publication number: CN211688736U) discloses an integrated sewage treatment device. This utility model uses steel pipes with threads at both ends to pass through the aerobic tank, biofilm tank and clear water disinfection tank inside the shell. These internal steel pipes are used for reflux and aeration, so that all the pipelines of the entire integrated sewage treatment device are enclosed inside the shell, which is conducive to the transportation of sewage treatment equipment and the equipment occupies little space.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the sewage inlet pipes of some existing integrated rural sewage treatment equipment buried underground lack protective structures. Being buried underground for a long time can easily lead to corrosion of connecting bolts and accelerated aging of rubber gaskets, which can easily cause sewage leakage and soil pollution. Furthermore, disassembly is inconvenient when maintaining the pipes in the future.

[0006] Therefore, an integrated rural sewage treatment device is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide an integrated rural sewage treatment device that can solve the problems of existing integrated rural sewage treatment equipment buried underground, where the sewage inlet pipes lack protective structures, are prone to corrosion of connecting bolts and accelerated aging of rubber gaskets due to long-term burial, leading to sewage leakage, soil pollution, and inconvenience in disassembly during later maintenance.

The fixing hole is opened inside the sealing cover. The surface of the sealing sheet is fixedly connected to the inner wall of the fixing hole. The inner wall of the sealing sheet is in close contact with the surface of the sewage conveying pipe.

[0010] Preferably, a sealing ring is fixedly connected to the left side of the protective cover, and the left side of the sealing ring is in close contact with the right side of the limiting ring.

[0027] 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.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] An integrated rural sewage treatment device includes a sewage treatment integrated equipment body 1, a sewage inlet pipe 7 fixedly connected to the left side of the sewage treatment integrated equipment body 1, a protective cover 3 provided on the surface of the sewage inlet pipe 7, a sealing mechanism 6 provided on the left side of the protective cover 3, a sewage conveying pipe 2 provided on the left side of the sewage inlet pipe 7, and a connecting mechanism 8 provided on the left side of the sewage inlet pipe 7.

[0030] The sealing mechanism 6 includes a sealing cover 601, a sealing plate 602, a limiting ring 603, and a fixing hole 604. The inner wall of the sealing cover 601 is threadedly connected to the surface of the protective cover 3. The limiting ring 603 is fixedly connected to the inner wall of the sealing cover 601. The fixing hole 604 is opened inside the sealing cover 601. The surface of the sealing plate 602 is fixedly connected to the inner wall of the fixing hole 604. The inner wall of the sealing plate 602 is in close contact with the surface of the sewage conveying pipe 2.

[0031] In this embodiment: During the production of the integrated sewage treatment equipment body 1, the protective cover 3 is welded to the surface of the sewage inlet pipe 7 using argon arc welding. Then, the sewage inlet pipe 7 is welded to the integrated sewage treatment equipment body 1. At this time, a gap is formed between the protective cover 3 and the sewage inlet pipe 7, which facilitates the subsequent bolt 801 passing through the sewage inlet pipe 7 and the sewage delivery pipe 2 from the right side. Then, the sewage delivery pipe 2 is passed through the elastic methyl silicone rubber sealing sheet 602, and the sealing cover 601 is put on. The sewage inlet pipe 7 and the sewage delivery pipe 2 are connected by bolts 801, nuts 803 and rubber sealing gaskets 802. Then, the sealing cover 601 and the protective cover 3 are rotated. Tighten the screws, and the sealing ring 11 fits into the limiting ring 603. The sealing sheet 602 wraps around the conveying pipe to form a sealed space. After being buried underground, it can isolate corrosive substances, extend the life of the rubber sealing gasket 802, and prevent the bolts 801 and nuts 803 from rusting. This makes it convenient to disassemble and maintain the sewage conveying pipe 2 in the later stages. It solves the problem that some existing rural sewage treatment integrated equipment sewage inlet pipes buried underground do not have a protective structure. Long-term burial underground can easily lead to corrosion of connecting bolts and accelerated aging of rubber sealing gaskets, which can easily lead to sewage leakage, soil pollution, and inconvenience in disassembly during later maintenance.

[0032] Specifically, such as Figure 1 , Figure 5 and Figure 6 As shown, a sealing ring 11 is fixedly connected to the left side of the protective cover 3, and the left side of the sealing ring 11 is in close contact with the right side of the limiting ring 603.

[0033] Specifically, such as Figure 2 , Figure 3 and Figure 6 As shown, the inner wall of the protective cover 3 has a through hole 12. The surface of the sewage inlet pipe 7 is in contact with the inner wall of the through hole 12. The connection between the protective cover 3 and the sewage inlet pipe 7 is welded by argon arc welding technology. There is a gap between the inner wall of the protective cover 3 and the sewage inlet pipe 7.

[0034] Specifically, such as Figure 5 As shown, anti-slip blocks 9 are fixedly connected to the surface of the sealing cover 601. The number of anti-slip blocks 9 is several and they are evenly distributed on the surface of the sealing cover 601.

[0035] In this embodiment: the sealing ring 11 on the left side of the protective cover 3 is in close contact with the limiting ring 603 on the inner wall of the sealing cover 601. With the threaded connection between the sealing cover 601 and the protective cover 3, the seal at the connection between the sealing cover 601 and the protective cover 3 can be guaranteed. The protective cover 3 is welded to the sewage inlet pipe 7 by argon arc welding. The through hole 12 at the connection is designed to facilitate welding on the surface of the sewage inlet pipe 7. The gap between the sewage inlet pipe 7 and the protective cover 3 facilitates the insertion of the bolt 801 from the right side, providing convenience for the connection between the sewage conveying pipe 2 and the sewage inlet pipe 7. The anti-slip block 9 on the sealing cover 601 increases the friction and facilitates manual rotation operation, ensuring that the installation and disassembly of the sealing cover 601 is easy and labor-saving.

[0036] Specifically, such as Figure 4 As shown, the connecting mechanism 8 includes several bolts 801, rubber sealing gaskets 802 and several nuts 803. Nuts 803 are located on the left side of the sewage conveying pipe 2, bolts 801 are located on the right side of the sewage inlet pipe 7, and rubber sealing gaskets 802 are located between the opposite sides of the sewage conveying pipe 2 and the sewage inlet pipe 7. The sewage conveying pipe 2 and the sewage inlet pipe 7 are connected by bolts 801 and nuts 803.

[0037] Specifically, such as Figure 5 As shown, fastening blocks 10 are fixedly connected to the top and bottom of the left side of the sealing cover 601.

[0038] In this embodiment: In the connecting mechanism 8, the bolt 801 and nut 803, together with the rubber sealing gasket 802, realize a stable connection and seal between the sewage conveying pipe 2 and the sewage inlet pipe 7, ensuring the sealing and stability of sewage conveying. The fastening blocks 10 on both sides of the sealing cover 601 facilitate the insertion of an external rod-shaped tool. By rotating the external rod-shaped tool, the sealing cover 601 can be tightened.

[0039] Specifically, such as Figure 1 and Figure 5 As shown, the sealing cover 601 and the protective cover 3 are both made of high-density polyethylene, and the sealing sheet 602 and the sealing ring 11 are both made of methyl silicone rubber.

[0040] Specifically, such as Figure 1 As shown, a drain pipe 4 is fixedly connected to the top of the integrated sewage treatment equipment body 1, and a valve 5 is installed inside the drain pipe 4.

[0041] In this embodiment: the sealing cover 601 and the protective cover 3 are made of high-density polyethylene, which has good corrosion resistance and mechanical strength and is suitable for complex underground environments. The sealing sheet 602 and the sealing ring 11 are made of methyl silicone rubber, which has good elasticity and sealing performance, making it easy for the sewage conveying pipe 2 to pass through and can fit tightly against the surface of the sewage conveying pipe 2. By connecting the external pipe to the drain pipe 4 and opening the valve 5, the treated sewage can be extracted.

[0042] Working principle: During the production stage of the integrated sewage treatment equipment body 1, the protective cover 3 is welded to the surface of the sewage inlet pipe 7 using argon arc welding technology. Then, the sewage inlet pipe 7 is welded to the integrated sewage treatment equipment body 1. At this point, a gap is formed between the protective cover 3 and the sewage inlet pipe 7, facilitating the subsequent insertion of bolts 801 from the right side into the sewage inlet pipe 7 and the sewage delivery pipe 2, providing a basis for subsequent sealing operations. During use, because the sealing plate 602 is made of highly elastic methyl silicone rubber, the sewage delivery pipe 2 can easily pass through the sealing plate 602, allowing the sealing cover 601 to be installed. The sealing plate 602 is fitted onto the surface of the sewage conveying pipe 2. At this time, the inner wall of the sealing plate 602 will contact the surface of the sewage conveying pipe 2. Then, the sewage conveying pipe 2 and the sewage inlet pipe 7 are bolted together by the bolt 801 and nut 803 through the rubber sealing gasket 802 to complete the connection. Next, the anti-slip block 9 is held and rotated to connect the inner wall of the sealing plate 601 to the surface of the protective cover 3 and tighten it. At this time, the sealing ring 11 on the left side of the protective cover 3 and the limiting ring 603 on the inner wall of the sealing plate 601 are tightly fitted to achieve the initial seal at the connection. At the same time, the sealing plate 602, by its own... The elastic body tightly wraps around the surface of the sewage conveying pipe 2, forming another sealing barrier. This completely encloses the bolts 801, nuts 803, and rubber gasket 802 within the space formed by the sealing cap 601, protective cover 3, sealing plate 602, and sealing ring 11. When the integrated sewage treatment equipment body 1 is buried in rural land, this sealed space effectively isolates moisture and corrosive substances from the soil, preventing the bolts 801 and nuts 803 from rusting and slowing the aging rate of the rubber gasket 802, thereby extending its service life. Furthermore, it facilitates the cleaning of the sewage conveying pipe 2 later. During maintenance, the sewage conveying pipe 2 can be easily disassembled without worrying about disassembly difficulties caused by the corrosion of bolts 801 and nuts 803. This solves the problem that some existing rural sewage treatment integrated equipment sewage inlet pipes buried underground lack protective structures, are prone to corrosion of connecting bolts and accelerated aging of rubber gaskets due to long-term burial underground, which can easily lead to sewage leakage and soil pollution. Furthermore, the disassembly is also inconvenient during later maintenance. It should be noted that the sewage treatment integrated equipment body 1 is a mature technology that has been published and will not be elaborated here.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
