[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater neutralization tank. Background Technology

[0002] Ammonia nitrogen wastewater has a wide range of sources, including fertilizer production, oil refining, inorganic chemicals, meat processing, feed production, non-ferrous metal smelting, agricultural production, animal excrement, and leachate from daily landfills. Wastewater neutralization involves adding chemicals to a wastewater tank to react with the wastewater until it meets discharge standards. For example, Chinese Patent 202020012268.8 discloses a chemical wastewater neutralization tank capable of uniformly spraying chemicals, comprising a wastewater neutralization tank, a spray pipe installed inside the tank, and a lifting mechanism for repeatedly spraying chemicals up and down in cycles.

[0003] In the aforementioned existing technology, spraying is carried out by a nozzle buried in the sewage tank. In batch sewage treatment or relatively simple neutralization systems, the dosing cycle, dosage and type of agent are set. In this case, the spraying is intermittent and there are spraying stoppage states. In the spraying stoppage state, the spray nozzle is located in the sewage, which contains various impurities, suspended solids or sediments. These substances may accumulate at the spray nozzle and cause blockage. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a sewage neutralization pool to solve the technical problem in the prior art where sewage contains various impurities, suspended solids or sediments, which may accumulate at the spray nozzle and cause blockage.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a wastewater neutralization tank, comprising:

[0007] Sewage tank;

[0008] A spray pipe assembly, comprising at least one spray pipe body suspended in the sewage tank, wherein the outer periphery of the spray pipe body is provided with a plurality of spray holes along the length direction;

[0009] A collar assembly, fitted onto the spray tube assembly, having a shielding surface that covers the spray orifice; and

[0010] The telescopic mechanism has its movable end connected to the collar assembly, which pushes the collar assembly to move axially along the spray tube assembly so that the shielding surface of the collar assembly has a first position state that exposes the spray hole and a second position state that covers the spray hole.

[0011] In some embodiments, the collar assembly includes a collar frame and a base frame. The collar frame corresponds one-to-one with the spray tube and is sleeved on it. The collar frame has rings that correspond one-to-one with the spray holes. The collar frame is connected to the base frame.

[0012] In some embodiments, the collar assembly includes a collar frame and a base frame, the telescopic mechanism is mounted on the sewage tank, and its movable end is movably connected to the base frame.

[0013] In some embodiments, the base frame is annular in shape and coaxial with the rotation center of the spray pipe assembly. The movable end of the telescopic mechanism is connected to a sleeve coaxial with the rotation center of the spray pipe assembly, and the base frame is rotatably connected to the inner side of the sleeve.

[0014] In some embodiments, a rotary drive mechanism is further included, the movable end of which is connected to the spray pipe assembly to rotate the spray pipe assembly within the sewage tank.

[0015] In some embodiments, the spray pipe assembly further includes a main pipe and a rotary joint coaxially arranged at the rotation center of the spray pipe assembly. One end of the rotary joint is connected to the main pipe, and the other end is connected to a liquid supply pipe. A plurality of branch pipes extend from the end of the main pipe away from the rotary joint, and the branch pipes are connected to the ends of the spray pipe body one by one.

[0016] In some embodiments, the rotary drive mechanism includes a drive motor, a first synchronous pulley, a second synchronous pulley, and a synchronous belt.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] To address the technical problem of wastewater containing various impurities, suspended solids, or sediments accumulating at the spray nozzle and causing blockages, this invention provides a wastewater neutralization tank that can cover the spray nozzles when spraying is stopped, preventing the accumulation of various impurities, suspended solids, or sediments at the spray nozzles and thus reducing the probability of blockages.

[0035] It should be noted that the wastewater neutralization tank described in this utility model is used for, but not limited to, ammonia nitrogen wastewater treatment. For ease of explanation, this utility model only uses the application of the wastewater neutralization tank to ammonia nitrogen wastewater treatment as an example. The principle of the wastewater neutralization tank applied to other types of wastewater is essentially the same as that applied to ammonia nitrogen wastewater treatment, and will not be elaborated here.

[0036] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a wastewater neutralization tank in one embodiment of the present invention. The wastewater neutralization tank includes a wastewater tank 1, a spray pipe assembly 2, a collar assembly 3, and a telescopic mechanism 4. The spray pipe assembly 2 includes at least one spray pipe body 21 suspended in the wastewater tank 1. Preferably, there are four spray pipe bodies 21 in one spray pipe assembly 2, which are arranged in a circumferential array. The outer circumference of each spray pipe body 21 has multiple spray holes 201 along its length. The spray pipe bodies 21 are suspended in the wastewater tank 1 and evenly distributed to allow the chemical solution to be sprayed out and mixed with the wastewater. The collar assembly 3 is sleeved on the spray pipe assembly 2 and has... The shielding surface of the spraying hole is specifically fitted onto each spraying tube body 21; the movable end of the telescopic mechanism 4 is connected to the collar assembly 3, pushing the collar assembly 3 to move axially along the spraying tube assembly 2, so that the shielding surface of the collar assembly 3 has a first position state exposing the spraying hole 201 and a second position state covering the spraying hole 201. In the first position state, the spraying hole 201 can spray liquid normally. In the second position state, since the spraying hole 201 is covered, various impurities, suspended solids or sediments in the sewage can be prevented from accumulating at the spraying port, reducing the probability of clogging.

[0037] In this embodiment, in order to improve the uniformity of pesticide coverage, multiple sets of spray holes 201 are arranged along the spray pipe body 21, with four spray holes 201 in each set, and they are distributed in a circular pattern on the outer periphery of the spray pipe body 21. Thus, during spraying, a spray pattern is formed with the spray pipe body 21 as the central axis and diffuses outwards. Combined with the array distribution of the four spray pipe bodies 21, the pesticide solution is diffused to different depths of the sewage, thereby improving the diffusion effect of the pesticide solution in the sewage.

[0038] Understandably, each group should have at least one spray nozzle 201, depending on the requirements. If there is only one spray nozzle 201, it can be set downwards.

[0039] It should be noted that the telescopic mechanism 4 can be a mechanism with linear telescopic function, such as a hydraulic push rod or a lead screw guide pair.

[0040] In one embodiment, please refer to Figure 2 and Figure 3 In order to form a first position state and a second position state, and to switch between the two position states under the control of the telescopic mechanism 4, the collar assembly 3 includes a collar frame 31 and a base frame 32. The collar frame 31 corresponds one-to-one with the spray tube body 21 and is sleeved on it. The collar frame 31 has a ring body 33 that corresponds one-to-one with the spray holes 201. The collar frame 31 is connected to the base frame 32. Each ring body 33 corresponds to each group of spray holes 201. In the first position state, the ring body 33 is located beside each group of spray holes 201. In the second position state, the ring body 33 covers the corresponding group of spray holes 201.

[0041] In this embodiment, multiple rings 33 are connected together by multiple straight rods to form a structure that is fitted onto the spray tube 21.

[0042] In one embodiment, please refer to Figure 2 and Figure 3 In order to switch between the first position state and the second position state while avoiding interference with the rotation drive, the telescopic mechanism 4 is installed on the sewage tank 1, and its movable end is movably connected to the base frame 32.

[0043] Specifically, to avoid interference with the rotation drive, the base frame 32 is annular in shape and coaxial with the rotation center of the spray pipe assembly 2. The movable end of the telescopic mechanism 4 is connected to a sleeve 41 coaxial with the rotation center of the spray pipe assembly 2. The base frame 32 is rotatably connected to the inside of the sleeve 41. The sleeve 41 also has a front limiting ring and a rear limiting ring that restrict the base frame 32 within it. When the telescopic mechanism 4 pushes the sleeve 41 to move, it forms a pushing force against the base frame 32, thereby pushing the entire collar assembly 3, which allows switching between the first position state and the second position state. When the spray pipe assembly 2 rotates, it will drive the collar assembly 3 to rotate together. Since the base frame 32 is rotatably connected to the inside of the sleeve 41, it will rotate within the sleeve 41 during rotation, thus avoiding interference with the telescopic mechanism 4.

[0044] Furthermore, in order to supply pesticide solution to each spray tube 21 during rotation, the spray tube assembly 2 also includes a main pipe 22 and a rotary joint 23 coaxially arranged at the rotation center of the spray tube assembly 2. One end of the rotary joint 23 is connected to the main pipe 22, and the other end is connected to a pesticide supply pipe 24. The pesticide supply pipe 24 is connected to the rotary joint 23, so that the pesticide supply can be normally delivered when the main pipe 22 rotates. Multiple branch pipes 25 extend from the end of the main pipe 22 away from the rotary joint 23. The branch pipes 25 are connected to the ends of the spray tubes 21 one by one. During pesticide supply, the pesticide can enter the main pipe 22 through the rotary joint 23, then enter each branch pipe 25, and finally be delivered to each spray tube 21.

[0045] As is understandable, the liquid supply pipe 24 is connected to the liquid medicine tank. The liquid medicine in the liquid medicine tank is pumped through the liquid supply pipe 24 by the pump body. This is a conventional method of liquid medicine delivery, which will not be elaborated on here.

[0046] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 3 In order to agitate the wastewater while spraying the pesticide, the wastewater neutralization tank also includes a rotary drive mechanism 5, the movable end of which is connected to the spray pipe assembly 2, so that the spray pipe assembly 2 rotates in the wastewater tank 1, thereby agitating the wastewater and improving the mixing effect of the wastewater and pesticide.

[0047] Understandably, during the mixing process, the multiple spray tubes 21 in the spray tube assembly 2 act as agitators.

[0048] In one feasible embodiment, the rotary drive mechanism 5 is a rotating handle connected to the spray pipe assembly 2, which can be manually rotated to drive the spray pipe assembly 2 to rotate.

[0049] In another feasible embodiment, please refer to Figure 2 and Figure 3In order to drive the rotation of the spray pipe assembly 2, the rotary drive mechanism 5 includes a drive motor 51, a first synchronous pulley 52, a second synchronous pulley 53, and a synchronous belt 54. The drive motor 51 is mounted on the sewage tank 1, and its output shaft is connected to the first synchronous pulley 52. ​​The second synchronous pulley 53 is coaxially connected to the main pipe 22. The main pipe 22, the branch pipe 25, and the spray pipe body 21 are all rigid pipes. When the main pipe 22 rotates, it can drive the branch pipe 25 and the spray pipe body 21 to rotate together. The synchronous belt 54 meshes with the first synchronous pulley 52 and the second synchronous pulley 53 for transmission. The drive motor 51 drives the first synchronous pulley 52 to rotate, and the synchronous belt 54 drives the second synchronous pulley 53 to rotate, thereby forming a rotational drive for the spray pipe assembly 2.

[0050] Understandably, the first synchronous pulley 52, the second synchronous pulley 53, and the synchronous belt 54 constitute a synchronous belt drive. For the drive motor 51 to drive the spray pipe assembly 2, belt drive, chain drive, or gear drive can also be used.

[0051] It should be noted that the main pipe 22 passes through the sewage tank 1 and is rotatably connected to the sewage tank 1 through a bearing. A mechanical seal is provided between the main pipe 22 and the sewage tank 1 to prevent sewage leakage. The mechanical seal structure is a mature existing technology and will not be described in detail here.

[0052] Furthermore, in order to install and protect the rotary drive mechanism 5 outside the sewage tank 1, a transmission chamber 101 is provided on one side of the sewage tank 1, and the rotary drive mechanism 5 is installed on the transmission chamber 101.

[0053] In one embodiment, please refer to Figure 5 and Figure 6 In order to cover a large sewage tank, multiple spray pipe groups 2 are arranged to cover it. The number of spray pipe groups 2 is multiple, and the multiple spray pipe groups 2 are arranged at equal intervals along the width direction in the sewage tank 1.

[0054] Furthermore, in order to drive multiple collar assemblies 3 to move via a telescopic mechanism 4, adjacent sleeves 41 are connected by a bracket.

[0055] Understandably, when a sleeve 41 is pushed to move, since multiple sleeves 41 are connected together by a bracket, all sleeves 41 are pushed, thereby pushing multiple collar assemblies 3.

[0056] Furthermore, in order to drive the rotation of multiple second synchronous pulleys 53 by a drive motor 51, adjacent second synchronous pulleys 53 are meshed and transmitted through a secondary synchronous belt 54.

[0057] Understandably, when the transmission reaches the first second synchronous pulley 53 and it rotates, it can drive the auxiliary synchronous belt 54 to drive the second second synchronous pulley 53 to rotate, and so on, so that all the second synchronous pulleys 53 can rotate, forming a rotation drive for multiple spray pipe assemblies 2.

[0058] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail as follows: When spraying is required, the ring 33 is located beside the spray hole 201. Under the supply of liquid medicine from the liquid medicine supply pipe 24, the liquid medicine flows sequentially into the main pipe 22, the branch pipe 25 and the spray pipe body 21, and is sprayed out from the spray hole 201. When spraying is not required, under the drive of the telescopic mechanism 4, the sleeve 41 and the collar assembly 3 move together to cover the spray hole 201 with the ring 33. In the above process, the spray pipe assembly 2 can be driven to rotate in the sewage tank 1 by the rotation drive mechanism 5 to form a stirring.

[0059] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
