Description

Technical Field

[0001] This utility model relates to the field of wastewater purification technology, and in particular to an automatic dosing device for wastewater purification. Background Technology

[0002] With the acceleration of global industrialization and the expansion of urbanization, water pollution has become a key challenge restricting sustainable social development. The continuous increase in industrial wastewater, domestic sewage, and agricultural non-point source pollution has led to frequent exceedances of chemical oxygen demand (COD), ammonia nitrogen, heavy metals, and organic pollutants in water bodies, seriously threatening ecological security and human health. Against this backdrop, wastewater treatment technology, as a core component of water environment management, directly affects the treatment effect and resource utilization level. However, in traditional wastewater treatment processes, the addition of chemical agents generally relies on manual experience or simple timed control, resulting in inaccurate dosage, low reaction efficiency, serious agent waste, and a high risk of secondary pollution. This makes it difficult to meet the demands of modern wastewater treatment for intelligent and refined management. Therefore, developing a highly efficient, precise, and automated dosing device has become an urgent need for technological upgrading in the industry.

[0003] An automatic dosing device for wastewater purification equipment, with announcement number CN111717976A, includes a storage tank. The top outer wall of the storage tank is provided with a tank cover. The bottom central outer wall of the storage tank is connected to a discharge pipe. The discharge pipe is movably installed at the bottom of the storage tank. An annular groove is opened in the center of the inner cavity of the discharge pipe. A baffle is provided in the inner cavity of the annular groove. A discharge port is opened on the bottom front outer wall of the baffle. The front inner wall of the discharge pipe is fixedly connected to a stop block, and the top outer wall of the stop block is in contact with the bottom outer wall of the baffle. In the device, the discharge pipe is moved upward, so that the connecting block is moved out of the inner cavity of the connecting groove. The support block is moved inward, so that the support block is completely moved into the inner cavity of the discharge pipe. The discharge pipe can be removed from the bottom of the storage tank to clean the discharge port of the baffle and avoid flocculant adhering or clogging inside the discharge port, which would affect the accuracy of the drug dispensing.

[0004] The existing technology described above uses a centralized feeding pipe to feed the chemicals. This centralized feeding can easily lead to the formation of "hot spots" in the wastewater tank, where the local concentration far exceeds the reaction requirements, while the concentration in other areas is insufficient. Furthermore, the chemicals need to be naturally diffused or inefficiently stirred to cover the entire tank, which prolongs the reaction time for flocculation and coagulation, resulting in poor wastewater treatment effect and low efficiency. Therefore, corresponding improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide an automatic dosing device for wastewater purification, in order to solve the problem mentioned in the background art that the existing automatic dosing devices for wastewater purification have too many dosing points and low wastewater treatment efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic dosing device for sewage purification, comprising a dosing tank, support legs, and a fixing plate. The dosing tank has support legs on both sides, and a fixing plate is fixed to one end of each support leg. The fixing plate has a fixing plate threadedly connected to both sides inside.

[0007] Both sides of the top of the dosing tank are connected to injection pipes. A cutting mechanism is provided at the top inside the dosing tank. A distribution cylinder is provided at the bottom inside the dosing tank, and distribution pipes are evenly connected to the outside of the distribution cylinder. Discharge nozzles are connected to both sides of the distribution pipes. A guide block is connected to the bottom inside the distribution cylinder, and the cross-section of the guide block is trapezoidal. An agitator is connected to the bottom of the distribution cylinder.

[0008] Furthermore, the cutting mechanism includes a drive motor, which is located at the top of the dosing tank. The output shaft of the drive motor is connected to a rotating shaft, and both sides of the rotating shaft are connected to a stirring rack. One side of each stirring rack is connected to a scraper, and the scraper is in contact with the inner wall of the dosing tank.

[0009] Furthermore, the stirring rack is provided in two sets outside the rotating shaft, with two racks in each set, and the stirring racks in each set face opposite directions.

[0010] Furthermore, each side of the stirring rack is connected to a mixing rod, and each mixing rod is provided with a cutting cavity. Cutting blades are evenly connected to both sides inside the cutting cavity, and the cutting blades inside the cutting cavity are staggered.

[0011] Furthermore, guide wheels are connected to both sides of the fabric cylinder, and guide grooves are provided on the inner wall of the dosing tank. The guide wheels slide inside the guide grooves, and the fabric cylinder is rotatably connected to the dosing tank through the guide wheels and guide grooves.

[0012] Furthermore, multiple distribution pipes are provided on the outside of the material distribution cylinder and are arranged in a ring shape.

[0013] Furthermore, the agitation assembly includes agitation rods fixed to both sides of the bottom end of the fabric cylinder, and agitation blades are fixed to both sides of the agitation rods.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the automatic dosing device for sewage purification can not only achieve the effect of stirring and crushing the agent, but also has the effect of uniformly dispersing the material. In addition, the agent can be stirred during the process to improve the sewage purification effect.

[0015] The drive motor drives the rotating shaft to rotate, and the cloth cylinder rotates synchronously. The guide wheel slides in the guide groove to limit and guide the rotation of the cloth cylinder. During the rotation of the cloth cylinder, the agent is discharged from multiple distribution pipes and discharge nozzles, realizing multi-point delivery of the agent. This allows the agent to be dispersed to different positions in the reaction tank, expanding the coverage area.

[0016] During the rotation of the rotating shaft, the stirring frame is driven to rotate, which agitates the chemicals added inside the dosing tank to prevent the chemicals from settling and clogging during the dosing process. In addition, during this process, the mixing rod rotates, and the staggered cutting blades rotate to crush the clumps of chemicals, increase the contact area between the chemicals and water, improve the dissolution efficiency, and help improve the wastewater purification efficiency.

[0017] Furthermore, during the rotation of the feeding cylinder, multiple stirring rods and agitator blades rotate to agitate the discharged agent, increasing the contact area with the wastewater, enhancing the micro-mixing of the agent and wastewater, and improving reaction efficiency.

Injection pipes 8 are connected to both sides of the top of the dosing tank 1. A cutting mechanism 7 is installed at the top of the dosing tank 1. The cutting mechanism 7 includes a drive motor 701, which is located at the top of the dosing tank 1. A rotating shaft 702 is connected to the output shaft of the drive motor 701, and stirring frames 703 are connected to both sides of the rotating shaft 702. A scraper 704 is connected to one side of each stirring frame 703, and the scraper 704 is in contact with the inner wall of the dosing tank 1.

[0030] Please refer to the details. Figure 1 , Figure 2 In this embodiment, wastewater purification agent is injected into the dosing tank 1 through the injection pipe 8. Then, the drive motor 701 is driven to rotate the rotating shaft 702, thereby driving multiple stirring racks 703 and mixing rods 705 to rotate.

[0033] Example 2

[0034] This embodiment differs from Embodiment 1. By utilizing the rotation of the distribution cylinder 3, the uniform distribution of the agent can be achieved, thus improving the wastewater treatment effect.
