Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and specifically refers to a multi-directional flow guiding system for sewage treatment. Background Art

[0002] In the field of sewage treatment, how to efficiently guide, treat, and discharge sewage has always been the focus of the industry. Traditional sewage treatment systems usually adopt a single flow guiding pipeline, which often leads to poor sewage flow in the pool body, easy formation of dead corners, and affects the treatment effect. To improve this problem, various multi-directional flow guiding devices have been developed in the industry, aiming to improve the treatment efficiency by changing the sewage flow path.

[0003] For example, patent number CN111218972A describes a water diversion and flow guiding device and method with a set of docking structure. This device guides the sewage flow by adding flow guiding plates. Although it improves the treatment efficiency to a certain extent, there are still problems such as inflexible flow guiding paths and difficult maintenance. In addition, when dealing with a large amount of sewage, this device is prone to affect the overall performance due to the blockage of the flow guiding plates.

[0004] Another example is that patent number CN117263341A proposes a flow guiding device for an efficient sedimentation tank, which realizes the diversion treatment of sewage through multiple flow guiding pipes. However, this system is prone to leakage problems at the pipe joints, and has poor adaptability to sewage with different flow rates and cannot be flexibly adjusted according to the actual situation. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a multi-directional flow guiding system for sewage treatment, aiming to solve problems such as single flow guiding path, low treatment efficiency, difficult maintenance, and poor adaptability in traditional sewage treatment systems.

[0006] Specifically, the technical solution provided by the present invention is: a multi-directional flow guiding system for sewage treatment, comprising:

[0007] A sewage tank, in which a set of three-way flow guiding mechanism is assembled. The three-way flow guiding mechanism treats and discharges the sewage to be treated stored in the sewage tank; a tank cover is assembled on the top of the sewage tank;

[0008] Three-way diversion mechanism, which is composed of a three-way part one and a three-way part two. On the side of the three-way part one, there is a water inlet exposed on the side of the sewage pool body. On the top of the three-way part one, there is an inlet maintenance opening exposed on the top of the pool cover body. At the bottom of the three-way part one, there is a bottom diversion opening one submerged under the water surface of the sewage to be treated. The water inlet, the inlet maintenance opening, and the bottom diversion opening one are integrally formed and connected to the three-way part one and communicate with each other. On the side of the three-way part two, there is a drain outlet exposed on the side of the sewage pool body. On the top of the three-way part two, there is an outlet maintenance opening exposed on the top of the pool cover body. At the bottom of the three-way part two, there is a bottom diversion opening two submerged under the water surface of the sewage to be treated. The drain outlet, the outlet maintenance opening, and the bottom diversion opening two are integrally formed and connected to the three-way part two and communicate with each other.

[0009] Furthermore, a matching handle is assembled on the pool cover.

[0010] Furthermore, the three-way part one and the three-way part two are vertically arranged diversion pipe bodies. Openings are processed on both side walls of the sewage pool, and the specifications of the openings are adapted to the aperture specifications of the water inlet of the three-way part one and the drain outlet of the three-way part two.

[0011] Furthermore, two through holes are processed on the pool cover, and the specifications of the through holes are adapted to the aperture specifications of the inlet maintenance opening of the three-way part one and the outlet maintenance opening of the three-way part two.

[0012] Furthermore, the fixed positions of the three-way part one and the three-way part two are arranged along the edge of the sewage pool body, and the three-way part one and the three-way part two are equidistantly arranged on a diagonal line of the sewage pool.

[0013] Furthermore, the pipe diameters of the three-way part one and the three-way part two are the same, and the positions and heights of the water inlet and the drain outlet are both lower than the water line in the sewage pool.

[0014] Furthermore, the vertical height position of the bottom diversion opening two is lower than that of the bottom diversion opening one. Due to the blockage of the bottom diversion opening two and the bottom diversion opening one, the water flow in the sewage pool does not flow parallelly, but flows into the bottom diversion opening two from the bottom diversion opening one in turn.

[0015] Furthermore, multiple sewage pools can be connected and used. The water inlet of one sewage pool is connected to the drain outlet of another sewage pool through a sealed flange to form a linkage type sewage treatment gravity flow system.

[0016] Furthermore, the water inlet depths of the bottom diversion opening one of the three-way part one and the bottom diversion opening two of the three-way part two range from - cm; the number of the three-way part one and the three-way part two in the same sewage pool can be selected in multiple groups and arranged in parallel according to the sewage flow. The water inlet distance of the bottom diversion opening one is small and reaches one-eighth of the sewage water surface; the water inlet distance of the bottom diversion opening two is large and reaches one-half of the water surface.

[0017] The advantages of the present invention compared with the prior art are as follows: (1) Multi-stage diversion: Through the combination of multiple three-way fittings one and three-way fittings two, multi-stage diversion of sewage is achieved, effectively avoiding the dead angle problem caused by the traditional single diversion path and improving the treatment efficiency; (2) Flexible maintenance: Both the three-way fitting one and the three-way fitting two are provided with inspection openings, which is convenient for daily maintenance and inspection, reducing the maintenance cost; (3) Strong adaptability: This system can flexibly increase or decrease the number of three-way fittings according to the size of the sewage flow, ensuring good treatment effects under various flow conditions; (4) Anti-leakage design: Each port is integrally formed, reducing the leakage risk at the connection and improving the stability and reliability of the system; (5) Easy to expand: Multiple sewage pools can be connected and used through sealed flange plates to form a linkage type sewage treatment gravity flow system, facilitating large-scale application.

[0023] The following further describes the present invention in detail with reference to the drawings.

[0024] Embodiment 1

[0025] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, this embodiment provides a multi-way diversion system for sewage treatment. A set of three-way diversion mechanisms are assembled in the sewage pool, and this mechanism includes a first three-way piece and a second three-way piece. The side of the first three-way piece is provided with a water inlet, the top is provided with an inlet maintenance opening, and the bottom is provided with a first bottom diversion opening; the side of the second three-way piece is provided with a drain outlet, the top is provided with an outlet maintenance opening, and the bottom is provided with a second bottom diversion opening. Each port is integrally formed and interconnected. A pool cover is assembled on the top of the sewage pool. The pool cover is provided with through holes adapted to the maintenance openings and is equipped with handles for easy opening. The first three-way piece and the second three-way piece are vertically arranged diversion pipe bodies, and the fixed positions are arranged along the edge of the sewage pool body and are equally spaced on a diagonal line. The position heights of the water inlet and the drain outlet are both lower than the water line in the sewage pool to ensure that sewage can flow in and out smoothly. The vertical height position of the second bottom diversion opening is lower than that of the first bottom diversion opening, so that sewage forms a sequential flow path in the pool body. Multiple sewage pools can be connected and used to form a linkage type sewage treatment gravity flow system to meet the sewage treatment requirements of different scales.

[0026] Specifically, the key components of this device include:

[0027] (1) Sewage pool 1

[0028] The sewage pool 1 is in a cuboid or cylinder shape structure and is used to store the sewage to be treated. The pool wall is strong and durable, can withstand a certain pressure, and prevents sewage from leaking. The pool bottom is flat, which is convenient for the sewage to be evenly distributed. As the main container for sewage treatment, it provides a place for the interaction between sewage and the diversion mechanism. The sewage pool 1 is connected to the first three-way piece 2 and the second three-way piece 4 through the openings on its two side walls. The opening specifications are adapted to the aperture specifications of the water inlet 201 and the drain outlet 402 of the three-way piece to ensure a tight connection and prevent sewage leakage.

[0029] (2) The first three-way piece 2 and the second three-way piece 4

[0030] The first three-way piece 2 and the second three-way piece 4 are both vertically arranged diversion pipe bodies and are made of high-quality corrosion-resistant materials. Each three-way piece is provided with a water inlet, an outlet maintenance opening, and a bottom diversion opening, and each port is integrally formed and interconnected. The water inlet and the drain outlet are located on the side of the three-way piece, which is convenient for connecting with external pipelines; the maintenance opening is located at the top, which is convenient for daily maintenance and repair; the bottom diversion opening is located at the bottom of the three-way piece and is used to guide the flow of sewage in the pool body. The first three-way piece 2 serves as the inlet for sewage to enter the sewage pool 1 and at the same time guides the sewage to flow towards the first bottom diversion opening; the second three-way piece 4 serves as the outlet for sewage to discharge from the sewage pool 1 and at the same time guides the sewage to flow in from the second bottom diversion opening. The two work together to achieve multi-path diversion of sewage. The first three-way piece 2 and the second three-way piece 4 are tightly connected to the openings on the side wall of the sewage pool 1 through connection methods such as flange plates or threads. Ensure that sewage will not leak during the diversion process, and at the same time, it is convenient for disassembly and repair.

[0031] (3)Pool cover 3

[0032] The pool cover 3 is a flat or arched structure and is made of lightweight and corrosion-resistant materials. The cover body is provided with through holes adapted to the inspection openings of the first three-way fitting 2 and the second three-way fitting 4, facilitating daily maintenance and inspection. At the same time, a sealing strip is provided at the edge of the cover body to ensure a tight fit with the top of the sewage pool 1. It protects the diversion mechanism in the sewage pool 1 from external interference and provides an inspection passage at the same time. The pool cover 3 is connected to the top of the sewage pool 1 by connection means such as bolts or buckles. Ensure that the cover body is stable and easy to open. The handle 301 is a cylindrical or arc-shaped structure and is made of strong and durable materials. The surface of the handle is provided with anti-slip textures, facilitating gripping and operation. It provides a convenient way to open the pool cover 3, ensuring that the operator can easily open the cover body for inspection and maintenance. The handle 301 is fixedly connected to the pool cover 3 by means such as welding, bolt connection or buckling.

[0033] When the device is working, sewage first enters the water inlet 201 of the first three-way fitting 2 through the water inlet pipe, and then flows into the sewage pool 1 along the internal flow path of the three-way fitting. In the sewage pool 1, the sewage is guided by the first bottom diversion port 203 at the bottom and flows towards the lower place, forming a certain water flow speed and direction. At the same time, part of the sewage may enter through the top inspection opening 202 of the first three-way fitting 2 for inspection or observing abnormal working conditions. As the sewage continuously flows in, the water level in the sewage pool 1 gradually rises. When the water level reaches or exceeds the second bottom diversion port 403, the sewage begins to enter the interior of the second three-way fitting 4 through this diversion port. In the second three-way fitting 4, the sewage flows along the flow path towards the drain port 402 and is finally discharged from the sewage pool 1 through the drain pipe.

[0034] During this process, due to the different vertical height positions of the first bottom diversion port 203 and the second bottom diversion port 403, and the blocking effect of the water flow in the sewage pool 1, the sewage forms a sequential flow path in the pool body. This flow mode not only improves the sewage treatment efficiency but also effectively avoids the dead corner problem caused by the traditional single diversion path.

[0035] In addition, the multi-directional diversion system of the present invention also has good adaptability and scalability. By adjusting the number of three-way fittings and connecting multiple sewage pools 1, a linkage type sewage treatment gravity flow system can be formed to meet the sewage treatment requirements of different scales and flows. At the same time, the setting of the inspection openings also facilitates the daily maintenance and inspection work. It can be seen that the multi-directional diversion system of the present invention has the advantages of simple structure, convenient maintenance, strong adaptability, high treatment efficiency, etc., and can be widely applied to sewage treatment projects of various scales.

[0036] Embodiment 2

[0037] Such as Figure 1 、 Figure 2 And Figure 3As shown in the figure, this embodiment provides a specific implementation of the working process of a multi-directional flow guiding system for sewage treatment:

[0038] I. Sewage inlet stage

[0039] The sewage is connected to the water inlet 201 of the tee 2 on the side wall of the sewage tank 1 through an external pipeline. The sewage enters the interior of the tee 2 from the water inlet 201, and then due to gravity and the guiding design, the sewage flows downward to the bottom guiding port 203. At this time, the sewage begins to enter the main part of the sewage tank 1, and the design of the bottom guiding port 203 ensures that the sewage can be evenly distributed at the bottom of the sewage tank, avoiding local accumulation.

[0040] II. Sewage flow stage in the tank

[0041] The sewage entering the sewage tank 1 begins to flow along the internal space of the sewage tank as the water level rises. Since the vertical height position of the bottom guiding port 403 is lower than that of the bottom guiding port 203, the sewage will be attracted by the bottom guiding port 403 during the flowing process, forming a downward flowing trend. During the flowing process, the sewage mixes with other sewage in the tank, increasing the treatment efficiency and avoiding the dead corner problem that may be caused by the traditional single guiding path.

[0042] III. Sewage discharge stage

[0043] When the sewage water level rises above the bottom guiding port 403, the sewage begins to enter the tee 4 through this guiding port. Inside the tee 4, the sewage flows along the flow path to the top water outlet inspection port 401 and the side drainage port 402. Usually, the sewage is discharged from the system through the drainage port 402, and the water outlet inspection port 401 is used for drainage operations during daily maintenance and repair in abnormal working states.

[0044] IV. System maintenance and expansion stage

[0045] The through holes on the tank cover 3 are adapted to the water inlet inspection port 202 of the tee 2 and the water outlet inspection port 401 of the tee 4, facilitating the operator for daily maintenance and repair. The setting of the handle 301 makes the tank cover 3 easy to open and close, further facilitating the maintenance work.

[0046] This system supports the connected use of multiple sewage tanks 1. By connecting the drainage port 402 of one sewage tank to the water inlet 201 of another sewage tank through a sealed flange, a linkage type sewage treatment gravity flow system can be formed to meet the sewage treatment requirements of a larger scale.

[0047] It can be seen that a multi-directional flow guiding system for sewage treatment according to the present invention realizes multi-path and efficient flow guiding treatment of sewage through the ingenious design of the three-way flow guiding mechanism. This system not only improves the efficiency and quality of sewage treatment, but also has good adaptability and scalability, and can meet the sewage treatment requirements of different scales and flows. At the same time, the daily maintenance and overhaul of the system have also become more convenient and efficient.

[0048] Embodiment III

[0049] As Figure 1 、 Figure 2 and Figure 3 shown, this embodiment provides a multi-directional flow guiding system for sewage treatment, including a sewage tank 1, a first three-way fitting 2, a tank cover 3 and a second three-way fitting 4. The sewage tank 1 is of a cuboid structure, cast with reinforced concrete, and has sufficient strength and durability. One opening adapted to the first three-way fitting 2 and the second three-way fitting 4 is respectively provided on both side walls of the sewage tank 1. Both the first three-way fitting 2 and the second three-way fitting 4 are vertically arranged flow guiding pipe bodies, made of stainless steel material, and have the characteristics of corrosion resistance and wear resistance. The water inlet 201 of the first three-way fitting 2 is connected to an external water inlet pipe, and the bottom flow guiding port one 203 faces the bottom of the sewage tank 1. The tank cover 3 covers the top of the sewage tank 1, and through holes adapted to the top maintenance ports of the first three-way fitting 2 and the second three-way fitting 4 are provided thereon, facilitating daily maintenance and overhaul. The handle 301 is fixedly connected to the edge of the tank cover 3, facilitating the operator to open and close the tank cover.

[0050] During operation, sewage enters the first three-way fitting 2 through the water inlet pipe, and then is evenly distributed to the bottom of the sewage tank 1 through the bottom flow guiding port one 203. As the water level rises, the sewage enters the second three-way fitting 4 through the bottom flow guiding port two 403 and finally discharges from the drain port 402 out of the system.

[0051] Embodiment IV

[0052] As Figure 1 、 Figure 2 and Figure 3 shown, this embodiment provides a specific implementation manner of the sewage tank 1. This embodiment is basically the same as Embodiment 1, except that the shape of the sewage tank 1 is cylindrical and the bottom is designed as a cone to better guide the flow of sewage. In addition, the materials of the first three-way fitting 2 and the second three-way fitting 4 are changed to titanium alloy to improve their high temperature and high pressure resistance performance and be applicable to harsher working environments. Under the guidance of the conical bottom, the flow of sewage in the sewage tank 1 is more uniform, further improving the treatment efficiency. At the same time, the three-way fittings made of titanium alloy ensure the stable operation of the system in a high-intensity working environment.

[0053] Embodiment V

[0054] As Figure 1 、 Figure 2and Figure 3 As shown, this embodiment provides an extended multi-directional flow guide system. On the basis of embodiment 1, multiple sewage tanks 1 and tee combinations are added to form a linkage sewage treatment gravity system. The drainage outlet of each sewage tank 1 is connected to the water inlet of the next sewage tank through the water inlet function of the tee 2 through the sealing flange to form a continuous sewage treatment process.

[0055] In addition, in order to enhance the flexibility and scalability of the system, the tee piece 1 2 and the tee piece 2 4 in this embodiment are designed to be detachable, so as to adjust the scale and layout of the system according to actual needs. At the same time, the through hole on the pool cover 3 is also designed to be adjustable in size to meet the requirements of tee inspection ports of different sizes.

[0056] During operation, sewage is sequentially treated in multiple sewage tanks 1, and the diversion mechanism in each sewage tank works according to the principle of embodiment 1, ensuring uniform distribution and efficient treatment of sewage. Finally, the sewage treated in multiple stages is discharged from the drainage port of the last sewage tank.

[0057] The above shows and describes the basic principles and main features of the present invention and the advantages of the invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
