[0002] Wastewater is mainly divided into domestic sewage, industrial wastewater and agricultural wastewater. Through physical, chemical and biological technologies, pollutants in wastewater are removed to meet discharge standards or reuse requirements. Currently, the main process of wastewater treatment is to add specific chemical agents to the wastewater to remove pollutants and purify the water.
[0003] However, existing drug delivery devices only deliver the agent to a certain location in the reaction tank, relying on the natural diffusion of the agent to purify the wastewater. This method is insufficient for fully purifying the wastewater and results in low wastewater treatment efficiency. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wastewater treatment chemical dosing device to solve the problem that the existing chemical dosing devices only add the agent to a certain position in the reaction tank and rely on the natural diffusion of the agent to purify the wastewater, which is difficult to fully purify the wastewater and has low wastewater treatment efficiency.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a wastewater treatment drug dosing device, including a wastewater reaction tank, a reaction box slidably installed in the wastewater reaction tank, a linear moving mechanism capable of driving the reaction box to move linearly on the wastewater reaction tank, a mixing chamber opened in the reaction box, a first pipe, a first water pump and a first connecting pipe arranged on one side of the reaction box, a second pipe, a second water pump and a second connecting pipe arranged on the other side, the input and output ends of the first water pump are respectively connected to the output end of the first pipe and the input end of the first connecting pipe, and the output end of the first connecting pipe is connected to the mixing chamber, the input and output ends of the second water pump are respectively connected to the output end of the second connecting pipe and the input end of the second pipe, and the input end of the second connecting pipe is connected to the mixing chamber, and a uniform dosing mechanism capable of dosing the drug into the mixing chamber is provided on the reaction box.

[0007] Preferably, the inlet of the first pipe is located at the bottom of one side of the reaction chamber, the outlet of the first connecting pipe is located at the top of the mixing chamber, and the inlet of the second connecting pipe is located at the bottom of the mixing chamber.
[0008] Preferably, the first connecting pipe and the second connecting pipe are respectively provided with a first valve and a second valve.
[0009] Preferably, the uniform dosing mechanism includes a storage tank and a dosing pump disposed on the top surface of the reaction chamber. The input end of the dosing pump is connected to the storage tank through a first delivery pipe. A round rod is rotatably mounted through the reaction chamber. The output end of the dosing pump is rotatably connected to the top end of the round rod through a second delivery pipe. The round rod has dosing holes evenly distributed on it.
[0010] Preferably, a plug is slidably installed inside the round rod, and a spring is provided inside the round rod, with both ends of the spring being fixedly connected to the plug and the round rod, respectively.
[0011] Preferably, the reaction chamber is provided with a stirring mechanism, which includes a plurality of mixing rods evenly distributed on a round rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention simultaneously activates the first and second water pumps, allowing wastewater from one side of the reaction tank to sequentially enter the mixing chamber through the first pipe and the first connecting pipe. Simultaneously, a uniform dosing mechanism evenly distributes chemicals into the mixing chamber, causing the wastewater and chemicals to mix and react. The purified wastewater is then sequentially transported to the other side of the reaction tank through the second connecting pipe and the second pipe. This structure allows the wastewater to mix with the chemicals within a confined space, ensuring thorough purification and improving the efficiency of wastewater treatment.
[0015] This invention uses a linear movement mechanism to drive the reaction tank to gradually move along the sewage reaction tank towards the side of the sewage to be purified, so as to ensure that the liquid levels on both sides of the reaction tank are relatively consistent and to prevent the liquid level on one side of the reaction tank from being too high and overflowing from the sewage reaction tank.
[0016] This invention uses a motor to drive a gear meshing ring, which in turn drives a round rod to rotate. This causes the mixing rod to stir and mix the wastewater and chemicals in the mixing chamber, further improving the effect of uniform mixing and purification of wastewater by the chemicals.

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0024] As attached Figure 1 To be continued Figure 4 This utility model provides a wastewater treatment drug dosing device, including a wastewater reaction tank 1, a reaction chamber 2 slidably installed inside the wastewater reaction tank 1, a linear movement mechanism 3 on the wastewater reaction tank 1 capable of driving the reaction chamber 2 to move linearly, a mixing chamber 4 opened inside the reaction chamber 2, a first pipe 5, a first water pump 6 and a first connecting pipe 7 arranged on one side of the reaction chamber 2, and a second pipe 9, a second water pump 10 and a second connecting pipe 11 arranged on the other side, the input and output ends of the first water pump 6 are respectively connected to the output end of the first pipe 5 and the input end of the first connecting pipe 7, and the output end of the first connecting pipe 7 is connected to the mixing chamber 4, the input and output ends of the second water pump 10 are respectively connected to the output end of the second connecting pipe 11 and the input end of the second pipe 9, and the input end of the second connecting pipe 11 is connected to the mixing chamber 4, and a uniform dosing mechanism 13 on the reaction chamber 2 capable of dosing the drug into the mixing chamber 4.
[0025] Among them, the linear motion mechanism 3 is an existing linear drive technology, which will not be described in detail here.
[0026] Specifically, the first water pump 6 and the second water pump 10 are started simultaneously, allowing the wastewater from one side of the reaction tank 2 to enter the mixing chamber 4 sequentially through the first pipe 5 and the first connecting pipe 7. At the same time, the uniform dosing mechanism 13 evenly adds the reagent into the mixing chamber 4, allowing the wastewater and the reagent to mix and react. Then, the purified wastewater is transported sequentially through the second connecting pipe 11 and the second pipe 9 to the other side of the reaction tank 2. Furthermore, as the purification process proceeds, the linear movement mechanism 3 can drive the reaction tank 2 to gradually move along the wastewater reaction tank 1 towards the side of the wastewater to be purified, ensuring that the liquid levels on both sides of the reaction tank 2 are relatively consistent, and preventing the liquid level on one side of the reaction tank 2 from overflowing from the wastewater reaction tank 1. With the above structure, the wastewater mixes with the reagent in a confined space, allowing the reagent to fully purify the wastewater and improving the efficiency of wastewater treatment.
[0027] Preferably, the front, rear, sides, and bottom of the reaction chamber 2 are all in contact with the inner wall of the wastewater reaction tank 1, so that the reaction chamber 2 separates the purified wastewater from the unpurified wastewater, reduces the ineffective consumption of reagents and reaction interference, and allows the reagents to concentrate on high-concentration pollutants, thereby improving purification efficiency.
[0028] Preferably, the input end of the first pipe 5 is located at the bottom of one side of the reaction chamber 2, the output end of the first connecting pipe 7 is located at the top of the mixing chamber 4, and the input end of the second connecting pipe 11 is located at the bottom of the mixing chamber 4.
[0029] Specifically, the wastewater can circulate from top to bottom within the mixing chamber 4, allowing the wastewater and the reagent to mix evenly.
[0030] Preferably, a first valve 8 and a second valve 12 are respectively provided on the first connecting pipe 7 and the second connecting pipe 11 to facilitate the drainage of sewage in the mixing chamber 4.
[0031] Preferably, the uniform dosing mechanism 13 includes a storage tank 131 and a dosing pump 132 disposed on the top surface of the reaction chamber 2. The input end of the dosing pump 132 is connected to the storage tank 131 through a first delivery pipe 133. A round rod 134 is rotatably mounted through the reaction chamber 2. The output end of the dosing pump 132 is rotatably connected to the top end of the round rod 134 through a second delivery pipe 135. The round rod 134 has dosing holes 136 evenly distributed. A plug 137 is slidably installed inside the round rod 134. A spring 138 is disposed inside the round rod 134. The two ends of the spring 138 are fixedly connected to the plug 137 and the round rod 134, respectively.
[0032] Specifically, during the dosing process, the existing control system controls the dosing pump 132 to deliver the medicine in the storage tank 131 to the round rod 134 in sequence through the first delivery pipe 133 and the second delivery pipe 135. The medicine is pushed downward to the blockage 137, compressing the spring 138, and discharged from the dosing hole 136, so that the medicine is mixed with the sewage. Conversely, the spring 138 rebounds, which can cause the blockage 137 to seal the dosing hole 136, preventing sewage from entering the round rod 134.
[0033] Preferably, the reaction chamber 2 is provided with a stirring mechanism 14, which includes a plurality of mixing rods 141 evenly distributed on a round rod 134. A motor 142 is fixedly installed on the top surface of the reaction chamber 2, and a gear 143 is fixedly connected to the output end of the motor 142. A toothed ring 144 is fixedly fitted on the top of the round rod 134, and the round rod 134 meshes with the toothed ring 144. A fixing frame 145 is also fixedly installed on the top surface of the reaction chamber 2, and the fixing frame 145 is fixedly connected to the end of the second delivery pipe 135 away from the dosing pump 132.
[0034] Specifically, the motor 142 drives the gear 143 to mesh with the gear ring 144, which in turn drives the round rod 134 to rotate, causing the mixing rod 141 to stir and mix the sewage and the agent in the mixing chamber 4, thereby further improving the effect of the agent on the uniform mixing and purification of sewage.
