Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a vortex water distributor. Background Art

[0002] During the operation of sewage treatment using hydrolysis acidification or anaerobic processes, sufficient mixing of the sewage entering the reactor with microorganisms is a necessary condition for the normal biochemical reaction and sewage purification. Various engineering measures are usually taken to optimize the hydraulic flow of the mixed liquid to achieve effects such as stirring, mixing, and upflow. Traditional methods include perforated water distribution pipes, ejectors, and submersible mixers. However, since the water nozzles of the perforated pipes or ejectors for perforated water distribution are relatively small, they are prone to clogging after long-term operation, resulting in uneven water distribution or short-circuiting. At the same time, the water inlet pipe is also prone to scaling. Submersible mixers have the disadvantages of high energy consumption, uneven stirring, and the presence of dead zones. Therefore, the utility model provides a vortex water distributor with a novel structure and clearing and descaling functions. Utility Model Content

[0003] In order to solve the deficiencies of the existing technology, the utility model provides a vortex water distributor that can improve the stirring and mixing effect.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0005] A vortex water distributor comprises a rectifying outer cover, a water inlet pipe, a cone top and a reflecting cone.

[0006] The top and bottom of the fairing cover are both opened, the fairing cover is arranged on the periphery of the water inlet pipe, and is connected to the reflective cone through a bracket;

[0007] The reflection cone is arranged below the water inlet pipe, the cone top is arranged on the top of the reflection cone, and the cone top and the bottom of the water inlet pipe form an annular gap for spraying the liquid in the water inlet pipe out.

[0008] Furthermore, it also includes a piston cylinder and a piston rod arranged in the reflecting cone. The top of the piston rod passes through the reflecting cone and is connected to the cone top for adjusting the height of the cone top.

[0009] Furthermore, the cone top is made of rubber.

[0010] Furthermore, the fairing cover, the water inlet pipe and the reflection cone are coaxially arranged.

[0011] Furthermore, the area between the rectifier cover and the water inlet pipe is the downflow area, and the outside of the rectifier cover is the upflow area. When the vortex water distributor is in operation, the downflow area and the upflow area form a vortex line.

[0012] Furthermore, the sidewall of the reflective cone is in a downwardly concave arc shape.

[0013] Furthermore, an umbrella-shaped cover is provided at the bottom of the water inlet pipe, and the cone top is located inside the umbrella-shaped cover and forms an annular gap with the umbrella-shaped cover.

[0014] Furthermore, the top and bottom of the fairing cover are both configured to be trumpet-shaped.

[0015] Furthermore, the fairing cover, the water inlet pipe and the reflective cone are made of one or more materials including stainless steel, PP, PE and PVC.

[0016] The beneficial effects of the present invention are:

[0017] 1. The treated sewage entering from the water inlet pipe is ejected from the narrow slit. Since the water outlet is approximately in the shape of a circular ring, the distribution space of the water outlet is larger than that of a circular hole, and the drainage effect is more obvious. The utility model can not only evenly distribute the treated water introduced into the reactor and fully mix it with the mixed liquid in the original reactor, but also its powerful drainage effect transfers the kinetic energy of the incoming water to the surrounding liquid medium, so that the water flow along the vortex line is multiplied compared with the incoming water flow. By arranging multiple vortex water distributors at the bottom of the hydrolysis acidification or anaerobic reactor, sufficient stirring of the microorganisms deposited in the lower part of the biochemical reactor is achieved, thereby achieving sufficient mixing of the microorganisms and the pollutants to be degraded. At the same time, the utility model is also suitable for other occasions that require mixing and stirring. Compared with existing water distribution or mixing methods, the utility model has the significant advantages of high efficiency and energy saving.

[0018] 2. After long-term use, the annular seam may occasionally be clogged with objects. The piston cylinder and piston rod are used to move the cone top up and down, and the water inlet volume is increased to flush away the clogged objects. When scaling occurs in the water inlet pipe, the piston cylinder and piston rod are used to raise the cone top to the highest position, and the end of the water inlet pipe is sealed. Then, acids and other descaling agents can be added to the water inlet pipe for descaling. In a hydrolysis acidification or anaerobic reactor, the water distribution pipes can be descaled one by one without the need for overall shutdown for maintenance. This has minimal impact on the pH environment in the biochemical reactor and does not affect the normal biochemical activities of microorganisms. After descaling is completed, the piston rod descends, the annular seam opens, and normal operation begins. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1As shown, this embodiment provides a vortex water distributor installed in a reactor, including a fairing cover 1, a water inlet pipe 2, a cone top 4, and a reflection cone 8.

[0023] Specifically, the fairing housing 1 is cylindrical, with both the top and bottom openings. Preferably, both the top and bottom of the fairing housing 1 are horn-shaped. The fairing housing 1 is coaxially arranged around the outer periphery of the water inlet pipe 2. The bottom of the fairing housing 1 is fixedly connected to the reflective cone 8 via a bracket 7. The outer wall of the water inlet pipe 2 is connected to the inner wall of the fairing housing 1, the bracket 7, or the reflective cone 8 via a support plate. Preferably, the outer wall of the water inlet pipe 2 is connected to the inner wall of the fairing housing 1 via a support plate.

[0024] Specifically, the reflective cone 8 is coaxially arranged below the water inlet pipe 2, the side wall of the reflective cone 8 is a downwardly concave arc, the cone top 4 is the cone center, the cone top 4 is arranged at the top of the reflective cone 8, and the cone top 4 and the bottom of the water inlet pipe 2 form an annular gap for spraying the liquid in the water inlet pipe 2. Preferably, as Figure 2 As shown, an umbrella-shaped cover 3 is provided at the bottom of the water inlet pipe 2 , and a cone top 4 is located inside the umbrella-shaped cover 3 , and an annular gap is formed between the cone top 4 and the umbrella-shaped cover 3 .

[0025] Specifically, the cone top 4 is made of rubber, and the fairing cover 1, the water inlet pipe 2, and the reflective cone 8 are made of corrosion-resistant materials such as stainless steel, PP, PE, and PVC, preferably PVC or 304 stainless steel, and most of them are PVC, with extremely low production costs.

[0026] The vortex water distributor provided in this embodiment is based on the working principle of the Venturi tube, which uses liquid with positive pressure to be ejected from the annular gap, generating negative pressure on the side, inducing the nearby liquid to flow forward along with the high-speed liquid flow, and achieving the purpose of doubling the flow rate through the induced jet. Figure 1 As shown, when the vortex water distributor is in operation, the area between the rectifying outer cover 1 and the water inlet pipe 2 is the downflow area, and the area outside the rectifying outer cover 1 is the upflow area. The downflow area and the upflow area form a vortex line 9, and the liquid in the reactor circulates along the route shown by the vortex line 9.

[0027] Preferably, the vortex water distributor further includes a piston cylinder 6 and a piston rod 5 arranged in the reflection cone 8. The top of the piston rod 5 passes through the reflection cone 8 and is connected to the cone top 4 for adjusting the height of the cone top 4.

[0028] like Figure 2 As shown, the umbrella cover 3 and the cone top 4 together form an annular gap. During normal operation, the cone top 4 is at the lowest position. When there is silt in the water inlet pipe 2, the piston cylinder 6 and the piston rod 5 can drive the cone top 4 to move up and down, and then increase the water intake to discharge the silt.

[0029] When scaling occurs in the water inlet pipe 2, Figure 3As shown, the cone top 4 can be moved to the highest position by the piston cylinder 6 and the piston rod 5 to close the umbrella cover 3, so that the descaling agent can be added into the water inlet pipe 2.

[0030] The above embodiments are only used to illustrate the technical ideas and features of the present invention and are not intended to be exclusive or limitative of the present invention. It should be understood by those skilled in the art that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
