[0002] Wastewater treatment is a comprehensive process that uses physical, chemical, and biological principles and technologies to remove or significantly reduce the concentration of various pollutants in wastewater, thereby ensuring that the wastewater meets national or local environmental standards or specific water quality requirements for reuse before discharge.

[0003] In existing technologies, wastewater treatment typically requires the addition of chemicals to remove pollutants. This is especially true when the wastewater contains multiple pollutants, such as organic matter, heavy metals, and suspended solids, requiring the addition of various chemicals to remove them. However, adding chemicals manually by scattering them around the water tank is inconvenient as operators often have to walk back and forth. Therefore, a chemical addition device for wastewater treatment is proposed to solve the above problems. Utility Model Content

[0011] As a further embodiment of this utility model: a top frame is fixedly connected to the top surface of the medicine storage box and behind each medicine inlet hopper. The top frame is generally L-shaped. A transmission wheel is rotatably connected to the top surface of the top frame and above the middle of each medicine inlet hopper. The transmission wheel extends into the medicine storage box from the pivot. A rotating rod is fixedly connected to the bottom end of the transmission wheel. A bearing sleeve is fixedly installed on the inner wall of the medicine storage box. The inner wall of the bearing sleeve is rotatably connected to the rotating rod. The bottom end of the rotating rod passes through the bearing sleeve. Several stirring rods are fixedly connected to the side of the bottom end of the rotating rod.

[0012] As a further embodiment of this utility model: a transmission belt is fitted on the outer side wall of the first transmission wheel, and a second transmission wheel is fitted on the inner side wall of the other side of the transmission belt. The bottom center of the second transmission wheel is rotatably connected to the top frame, and a gear is fixedly connected to the top center of each second transmission wheel.

Different types of solid agents for wastewater treatment can be stored in the storage tank through different feeding hoppers. Driven by a motor, the storage tank can move horizontally along the guide rail. During this process, the agent is continuously added to the wastewater by intermittently opening and closing the dispensing pipe, without manual operation. The intermittent dispensing helps to improve the reaction efficiency between the agent and the wastewater. During the movement of the storage tank, the rotating rods inside each storage chamber automatically rotate, thereby breaking up the agent with the stirring rod at the bottom of the rotating rod. This effectively prevents the agent from clumping and clogging the dispensing pipe, thus improving the uniformity of agent dispensing. Attached Figure Description

A transmission wheel 204 is rotatably connected to the top surface of the top frame 203 and above the middle of each medicine inlet hopper 202. The transmission wheel 204 extends into the medicine storage tank 201 from the pivot. A rotating rod 208 is fixedly connected to the bottom end of the transmission wheel 204. A bearing sleeve 210 is fixedly installed on the inner wall of the medicine storage tank 201. The inner wall of the bearing sleeve 210 is rotatably connected to the rotating rod 208. The bottom end of the rotating rod 208 passes through the bearing sleeve 210, and several stirring rods 209 are fixedly connected to the side of the bottom end of the rotating rod 208. Figure 2 As shown, the bearing sleeve 210 limits the rotation rod 208;

[0028] A transmission belt 205 is fitted onto the outer wall of transmission wheel 204, and a transmission wheel 206 is fitted onto the inner wall of the other side of transmission belt 205. The center of the bottom surface of transmission wheel 206 is rotatably connected to the top frame 203, and a gear 207 is fixedly connected to the center of the top surface of each transmission wheel 206.

Figure 5 As shown, the back of the medicine storage box 201 is provided with a threaded sleeve that matches the lead screw 103 and a sliding sleeve that matches the guide rail 104.

[0030] The working principle of this utility model:

[0031] When the device is in use, the mounting rod is fixed on both sides of the wastewater pool, and different agents are dispensed into the medicine storage tank 201 through the medicine feeding hopper 202 according to the nature of the wastewater. The motor 102 drives the lead screw 103 to rotate, thereby the thread on the surface of the lead screw 103 pushes the medicine storage tank 201 to move unidirectionally along the guide rail 104.

[0032] During this period, gear 218 moves along rack 216, and gear 218 rotates continuously and drives turntable 216 to rotate. Push shaft 217 pushes the inner side of moving frame 219, thereby driving moving plate 213 to reciprocate on the bottom surface of support block 212. Thus, through hole 214 is intermittently aligned with dispensing pipe 211, and the medicine inside medicine storage tank 201 falls into dispensing pipe 211 under the action of gravity, and is intermittently dispensed into wastewater pool through through hole 214.

[0033] Secondly, as gear 207 moves along rack 105, gear 207 rotates and drives transmission wheel 206 to rotate. Through transmission belt 205, transmission wheel 204 and rotating rod 208 rotate. The stirring rod at the bottom of rotating rod 208 disperses the medicine inside the medicine storage tank 201 to prevent the medicine from clumping and clogging the dispensing pipe 211.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
