Description

Technical Field

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

[0002] Adding precipitants is a core step in chemically enhanced sedimentation processes in wastewater treatment. By adding chemicals, suspended solids, colloidal particles, and some dissolved pollutants in the water are promoted to coagulate and settle. The role and principle of precipitants is to neutralize the surface charge of colloidal particles, disrupt their stability, and promote particle aggregation.

[0003] Currently, when adding precipitants to wastewater, the precipitants need to absorb water and expand before dissolving. If they are directly added to the water, a large amount of the agent may expand rapidly due to excessively high local concentrations, forming externally encapsulated but internally undissolved flocs, leading to clumping and affecting the subsequent sedimentation effect. Therefore, a new type of wastewater treatment precipitant addition device is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when adding precipitants to wastewater, the precipitants need to absorb water and expand before dissolving. If they are directly added to the water, a large amount of the agent may expand rapidly due to excessively high local concentration, forming externally encapsulated but internally undissolved colloids, leading to clumping and affecting the subsequent sedimentation effect. This invention provides a wastewater treatment solution.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: A wastewater treatment precipitant adding device includes: a water storage tank, with several clamping rings installed below the water storage tank, and a driving unit for driving the several clamping rings to move closer or further apart in pairs.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0017] The wastewater treatment precipitant addition device provided in this embodiment is mainly used to solve the problem that when precipitants are added to wastewater, they need to absorb water and expand before dissolving. If they are directly added to the water, a large amount of the agent may expand rapidly due to excessively high local concentrations, forming externally encapsulated but internally undissolved flocs, leading to clumping and affecting the subsequent sedimentation effect. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation: A wastewater treatment precipitant adding device includes: a water tank 1 with several clamping rings 2 at the bottom. In use, the user places the clamping rings 2 on both sides of the effluent pipe 13 of the wastewater sedimentation tank. Then, a drive unit 3 drives the clamping rings 2 in pairs to move them closer or further apart, thus restricting the position of the water tank 1 above the effluent pipe 13 of the wastewater sedimentation tank. The main components of the water tank 1 are: a main tank body 11 with a telescopic end 12 on one side, wherein the telescopic end 12 is a hollow structure and the effluent pipe 13 is fixedly inserted into its inner wall. In use, the user adds the precipitant into the main tank body 11 and opens the valve 14 on the surface of the effluent pipe 13. Under the action of gravity, the precipitant enters the effluent pipe 13 from the inside of the main tank body 11 and finally exits from the effluent pipe. The main components of the drive unit 3 are: The system consists of several torsion springs 34 and several adjusting blocks 33. The bottoms of the adjusting blocks 33 are rotatably mounted on several clamping rings 2 via the torsion springs 34. Since drive grooves 31 are provided at the bottom of the main housing 11, during use, the user rotates two positive and negative threaded screws 32 that are respectively inserted into the inner walls of the two drive grooves 31. This causes the adjusting blocks 33, which are respectively threaded onto the surfaces of the two positive and negative threaded screws 32, to slide on the inner walls of the two drive grooves 31. This further enables the pairwise driving of the clamping rings 2. In subsequent use, after the clamping rings 2 are all attached to the surface of the faucet in the sewage treatment tank, the torsion springs 34 will be twisted, thereby applying a force to the clamping rings 2 to compress the faucet in the sewage treatment tank, ensuring the limit of the main housing 11 above the faucet in the sewage treatment tank.

[0018] By installing several clamping rings 2 below the water storage tank 1, the user can place the faucet of the sewage treatment tank between the clamping rings 2 during use. Then, the drive unit 3 drives the clamping rings 2 to move closer to each other in pairs, thereby clamping the surface of the water pipe. In subsequent use, the user adds the flocculant into the water storage tank 1 and discharges the flocculant into the sedimentation tank through the water storage tank 1. This allows the flocculant to mix directly with the sewage sprayed from the outlet pipe 13. The impact force of the water flow can quickly disperse the agent into fine particles, avoiding concentrated accumulation of the agent and reducing the risk of clumping.

[0019] By setting a telescopic end 12 at one end of the main body 11, the user can adjust the position of the water outlet pipe 13 by adjusting the length of the telescopic end 12 during use, so that the water outlet position of the water outlet pipe 13 can be aligned with the faucet of the sewage treatment tank, ensuring that the impact force of the water flow can be fully utilized to disperse the agent.

[0020] like Figure 1 and Figure 4 As shown, in some embodiments, after the user adds a precipitant inside the main housing 11, a cover plate 4 needs to be placed on top of the main housing 11 to cover the opening above the main housing 11. The installation method of the torsion springs 34 is as follows: several mounting grooves 5 are respectively opened at the bottom of several adjusting blocks 33, and fixing rods 6 are fixedly installed on the inner walls of the mounting grooves 5. Several clamping rings 2 are slidably sleeved on the surfaces of the fixing rods 6. Since the torsion springs 34 are slidably sleeved on the surfaces of two fixing rods 6, one end of each torsion spring 34 is fixedly installed on both sides of the inner walls of the mounting grooves 5, and the other end of each torsion spring 34 is fixedly installed on both sides of two clamping rings 2. During use, the clamping rings 2 are all attached to... During the process of fitting the faucet surface in the sewage treatment tank, several torsion springs 34 are twisted, applying a force to several clamping rings 2 to return to their original position, so that the surfaces of several clamping rings 2 abut against the surface of the faucet in the sewage treatment tank. The telescopic end 12 includes: a water outlet 121 opened on the surface of the main body 11, and an extension tube 122 slidably sleeved on the surface of the water outlet 121. When in use, the user pulls the extension tube 122, so that the extension tube 122 slides on the surface of the water outlet 121, thereby adjusting the position of the water outlet pipe 13 fixedly inserted on the surface of the extension tube 122. Finally, the position of the extension tube 122 on the surface of the water outlet 121 is limited by the limiting unit 123, thereby limiting the position of the water outlet pipe 13.

[0021] like Figure 2As shown, in some embodiments, the main components of the limiting unit 123 are: an abutment bolt 1233 threaded into the surface of the outlet 121, and a through groove 1231 opened on the surface of the extension tube 122. In use, the user pulls the extension tube 122, inserts the abutment bolt 1233 into the inner wall of the through groove 1231, and then threaded into the surface of the outlet 121, so that the surface of the abutment bolt 1233 abuts against the surface of the extension tube 122, thereby limiting the extension tube 122 on the surface of the outlet 121. At the same time, an abutment edge 1232 is provided on the surface of the outlet 121. Therefore, in use, the inner wall of the extension tube 122 is attached to the surface of the abutment edge 1232, ensuring that the precipitant will not leak out from the extension tube 122.

[0022] The working process of this utility model is as follows: First, the user needs to place several clamping rings 2 in pairs on the faucet of the sewage treatment tank, and rotate the two positive and negative threaded screws 32 to make the inner walls of several clamping rings 2 fit against the surface of the faucet of the sewage treatment tank, thus completing the limitation of the main box 11 above the faucet of the sewage treatment tank. Secondly, the user pulls the extension tube 122 so that the extension tube 122 is on the surface of the outlet 121, and rotates the abutment bolt 1233 so that the surface of the abutment bolt 1233 abuts against the surface of the extension tube 122. This can limit the extension tube 122 on the surface of the outlet 121, that is, adjust the length of the telescopic end 12, so that the outlet pipe 13 can be aligned with the faucet of the sewage treatment tank to discharge the precipitant.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
