Description

Technical Field

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

[0002] Chemical agents are added during wastewater treatment to improve efficiency and quality, achieving better treatment results. The role of chemical agents is to promote the sedimentation of suspended or dissolved solids in wastewater, thereby forming precipitates and removing harmful substances from the wastewater. According to a search, Chinese patent publication number CN222138723U discloses a wastewater treatment chemical dosing device, including a support tank, a treatment tank, support legs, a tank cover, and a chemical spraying component.

[0003] While the above technical solution solves the problem that adding chemicals to a single location can lead to uneven distribution of chemicals in the wastewater, thus affecting the wastewater treatment effect, the chemicals are still added from the top of the wastewater during use. They need to gradually sink down to treat the wastewater at the bottom, which reduces the mixing speed between the chemicals and the wastewater. Furthermore, the fixed position of the stirring blades used to stir the wastewater means that only the same layer of wastewater can be stirred, which will affect the stirring effect of the wastewater.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0020] Example:

[0021] like Figure 1 and Figure 2 As shown, a wastewater treatment device for chemical dosing includes a base plate 1. A wastewater treatment tank 2 is fixedly installed on the upper surface of the base plate 1. A stirring mechanism is installed on the top of the wastewater treatment tank 2. The stirring mechanism includes a vertical pipe 3 that runs through the top of the wastewater treatment tank 2. The vertical pipe 3 can rotate and slide up and down on the top of the wastewater treatment tank 2. Multiple stirring tubes 4 are sequentially and interconnected on the outer surface of the vertical pipe 3. An L-shaped protruding rod 5 is fixedly connected to one side of the outer surface of the vertical pipe 3. A support ring 6 is fixedly connected to the top of the wastewater treatment tank 2. The top of the support ring 6 has an arc-shaped convex surface 7 that cooperates with the L-shaped protruding rod 5. An L-shaped frame 8 is fixedly installed on the top of the wastewater treatment tank 2. A splined shaft 11 is fixedly connected to the top end of the vertical pipe 3. A splined sleeve 12 is slidably fitted on the outer surface of the splined shaft 11. The splined sleeve 12 is rotatably connected to the L-shaped frame 8 through a bearing. The top of the L-shaped frame 8 is fixedly mounted with a first motor 9, and the output shaft of the first motor 9 is fixedly connected to a gear 10. The outer surface of the spline sleeve 12 is fixedly connected to a gear ring 13 that meshes with the gear 10.

[0022] In use, the first motor 9 rotates, which drives the spline sleeve 12 and spline shaft 11 to rotate through the gear 10 and gear ring 13. This, in turn, drives the vertical pipe 3 and the stirring pipe 4 to rotate. The rotation of the vertical pipe 3 drives the L-shaped convex rod 5 to rotate. With the cooperation of the arc-shaped convex surface 7, the vertical pipe 3 and the stirring pipe 4 can move up and down, thereby stirring different levels of sewage and improving the stirring effect.

[0023] like Figures 1 to 4As shown, a dosing mechanism that cooperates with the stirring mechanism is installed on the upper surface of the base plate 1. The dosing mechanism includes multiple outlet holes 14 on the outer surface of the stirring tube 4. A one-way valve is embedded and fixedly installed inside the outlet hole 14. A connecting sleeve 15 is rotatably and sealingly fitted at the top of the vertical tube 3. An opening 16 communicating with the inside of the connecting sleeve 15 is opened on the outer surface of the vertical tube 3. A reagent storage tank 17 and a delivery pump 18 are fixedly installed on one side of the top of the base plate 1. The input end of the delivery pump 18 is fixedly connected to the inside of the reagent storage tank 17. A hose 19 is fixedly connected between the output end of the delivery pump 18 and the inside of the connecting sleeve 15. A flow meter 20 is fixedly installed at one end of the hose 19.

[0024] The operation of the transfer pump 18 can extract the chemicals from the chemical storage tank 17 and deliver them through the hose 19 to the connecting sleeve 15. Then, it enters the vertical pipe 3 through the opening 16 and is finally sprayed out through the discharge hole 14. This allows for chemical addition from inside the sewage, which can improve the mixing speed of the chemicals and thus improve the sewage treatment efficiency. Furthermore, since the connecting sleeve 15 and the vertical pipe 3 are sealed and rotatably connected, the vertical pipe 3 can rotate normally. The flow meter 20 can be used to quantify the added chemicals.

[0025] A second motor 21 is fixedly installed on the top of the medicine storage tank 17, and a stirring rack is fixedly connected to the output shaft of the second motor 21.

[0026] The rotation of the second motor 21 can drive the stirring rack to rotate, which can stir the medicine in the medicine storage tank 17 and prevent sedimentation.

[0027] It should be noted that in this technical solution, a controller is fixedly installed on one side of the top of the base plate 1. The controller facilitates the control of the first motor 9, the transfer pump 18, the flow meter 20, and the second motor 21. The controller is a common technical means in this field and belongs to the prior art, so it is not described in detail. Furthermore, a sewage inlet is fixedly connected to the top of the sewage treatment tank 2, and a sewage outlet is fixedly connected to one side of the bottom of the sewage treatment tank 2, which facilitates the addition and discharge of sewage.

[0028] Working principle: When in use, the first motor 9 rotates, which drives the spline sleeve 12 and spline shaft 11 to rotate through the gear 10 and gear ring 13. This, in turn, drives the vertical pipe 3 and the stirring pipe 4 to rotate. The rotation of the vertical pipe 3 drives the L-shaped convex rod 5 to rotate. With the cooperation of the arc-shaped convex surface 7, the vertical pipe 3 and the stirring pipe 4 can move up and down, thereby stirring different levels of sewage and improving the stirring effect.

[0029] The operation of the transfer pump 18 can extract the chemicals from the chemical storage tank 17 and deliver them through the hose 19 to the connecting sleeve 15. Then, it enters the vertical pipe 3 through the opening 16 and is finally sprayed out through the discharge hole 14. This allows for chemical addition from inside the sewage, which can improve the mixing speed of the chemicals and thus improve the sewage treatment efficiency. Furthermore, since the connecting sleeve 15 and the vertical pipe 3 are sealed and rotatably connected, the vertical pipe 3 can rotate normally. The flow meter 20 can be used to quantify the added chemicals.
