Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically a dosing and mixing device for industrial wastewater treatment. Background Technology
[0002] Industrial wastewater refers to wastewater, sewage, and waste liquid generated during industrial production processes. It contains industrial production materials, intermediate products, by-products, and pollutants that are lost with the water. It is diverse and complex in composition. Direct discharge of industrial wastewater will cause great damage to the environment. Therefore, industrial wastewater needs to be treated before discharge.
[0003] In the process of industrial wastewater treatment, chemical agents (such as flocculants, coagulants, acid-base regulators, heavy metal scavengers, etc.) are added to achieve the precipitation, neutralization or complexation of pollutants. Many agents are usually added directly to the surface of wastewater or fixed points, which can easily cause local concentrations to be too high or too low, resulting in a long mixing time and affecting the reaction effect.

[0028] Example
[0029] Please see Figure 1-6In this embodiment of the present invention, a dosing and mixing device for industrial wastewater treatment includes a mixing tank 100, a storage tank 200, a wastewater tank 300, a spraying mechanism 400, and a water pump 500. The mixing tank 100 has two dosing ports 110 and one discharge port 120 on its top and bottom surfaces, respectively. A motor 140 is fixedly connected to the top surface of the mixing tank 100. A rotating shaft 150 is rotatably connected inside the mixing tank 100. The motor shaft of the motor 140 is driven by the rotating shaft 150. Several stirring rods 1 are fixedly connected to the outer wall of the rotating shaft 150. 51. Multiple storage tanks 200 are provided for storing different agents. The storage tanks 200 are installed outside the mixing tank 100. The top surface of the storage tank 200 is provided with a drug inlet 210. The storage tank 200 is connected to the dosing port 110 through a drug delivery pipe 220. The wastewater tank 300 is located below the mixing tank 100 and stores industrial wastewater to be treated. The spraying mechanism 400 includes a drug inlet pipe 410, which is rotatably connected to the top surface of the mixing tank 100. The bottom end of the spraying mechanism 400 located inside the mixing tank 100 is fixedly connected to the drug collection point. The collection box 420 has an internal cavity. Several stirring blades 421 are fixedly connected at equal angles to the outer wall of the collection box 420. Several circular tubes 430 are also fixedly connected at equal angles to the outer wall of the collection box 420. The collection box 420 and the circular tubes 430 are staggered, and the circular tubes 430 are connected to the interior of the collection box 420. Each end of the circular tubes 430 is screwed with a fan-shaped nozzle 440. A gear 450 is sleeved and fixed to the outer wall of the inlet pipe 410 near its top. The spraying mechanism 400 also includes a second motor 460. Fixedly connected to the top surface of the mixing tank 100, the motor shaft of motor 2 460 is connected to gear 2 470, which meshes with gear 1 450. Water pump 500 is installed on the top surface of the mixing tank 100. Water pump 500 is connected to discharge port 120 through connecting pipe 1 510 and to inlet pipe 410 through connecting pipe 2 520. Solenoid valves are installed on discharge port 120 and delivery pipe 220. Rotary joint 480 is installed at the top of inlet pipe 410, and connecting pipe 2 520 is connected to rotary joint 480.
[0030] Specifically, during use, the solenoid valve on the delivery pipe 220 is opened, allowing the medicine in the storage tank 200 to enter the mixing tank 100. The motor 140 is started to drive the rotating shaft 150 to rotate at high speed, causing the stirring rod 151 to form a unidirectional vortex inside the mixing tank 100, thus initially mixing the medicine. The solenoid valve on the discharge port 120 is opened, and the water pump 500 is started, allowing the water pump 500 to draw the mixed medicine from inside the mixing tank 100 through the connecting pipe 510 and send it into the mixing tank through the connecting pipe 520. Inside the inlet pipe 410, the liquid medicine enters the collection box 420 and is sprayed out from several fan-shaped nozzles 440. At the same time, the second motor 460 is started, causing the second gear 470 to mesh with the first gear 450, thereby driving the inlet pipe 410 to rotate the collection box 420. The fan-shaped nozzles 440 convert the liquid into a wide-angle fan-shaped spray, increasing the reaction surface area with the wastewater. Meanwhile, due to the rotation of the collection box 420, the stirring blades 421 agitate the wastewater, accelerating the reaction between the medicine and the wastewater.
[0031] like Figure 5 As shown, in this embodiment, baffles 431 are slidably arranged inside several circular tubes 430, and springs 432 are fixedly connected to the side wall of the baffles 431 facing the fan-shaped nozzle 440.
[0032] In this embodiment, the circular tube 430 serves as a drug delivery channel and can be made of corrosion-resistant stainless steel. One end of the circular tube 430 is connected to the cavity of the drug collection box 420, and the other end is screwed onto the fan-shaped nozzle 440. The baffle 431 is a circular flat plate that matches the inner diameter of the circular tube 430, with an O-ring sealing groove on its edge. An annular inner groove is provided in the area between the fan-shaped nozzle 440 and the baffle 431 inside the circular tube 430. Under the elastic force of the spring 432, the baffle 431... It will be close to the end of the circular tube 430 near the medicine collection box 420, so that the channel between the medicine collection box 420 and the circular tube 430 is sealed to prevent wastewater from entering the medicine collection box 420. When the water pump 500 starts and the mixed medicine flows from the medicine collection box 420 into the circular tube 430, the hydraulic pressure acts on the baffle 431, causing the baffle 431 to drive the spring 432 to contract. At this time, the medicine enters the area behind the baffle 431 through the annular groove inside the circular tube 430, and finally is sprayed out from the fan-shaped nozzle 440 to mix with the wastewater.
[0033] like Figure 4 As shown, in this embodiment, a plurality of guide plates 422 are fixedly connected at equal angles inside the drug inlet tube 410, and the circular tube 430 is located in the middle area between two guide plates 422.
[0034] In practice, when the medicine enters the collection box 420 from the inlet pipe 410, it is blocked and dispersed by the guide plate 422, so that the medicine flows to the circular pipe 430.
[0035] like Figure 1 and Figure 6As shown, in this embodiment, a fixing ring 130 is fixedly connected to the top surface of the mixing tank 100 at equal angles. The device also includes a mounting frame 600, which is a cylindrical structure used to place the medicine storage tank 200. The mounting frame 600 includes a base 610, a support ring 620 is provided above the base 610, and several connecting rods 630 are fixedly connected between the support ring 620 and the base 610. A support column 650 is fixedly connected to the bottom surface of the base 610, a connecting plate 660 is fixedly connected to the bottom end of the support column 650, and an arc plate 670 is fixedly connected to the end of the connecting plate 660. A plug-in block 640 is fixedly connected to the bottom surface of the base 610 near the arc plate 670, and the plug-in block 640 is plugged into the fixing ring 130.
[0036] In practice, depending on the type of medicine to be added, the corresponding number of medicine storage tanks 200 and mounting brackets 600 can be taken out. During installation, simply move the mounting bracket 600 to the position of the corresponding fixing ring 130 so that the arc plate 670 is in contact with the outer wall of the mixing tank 100. Then move the mounting bracket 600 down so that the plug-in block 640 is inserted into the hole groove of the fixing ring 130. Then insert the medicine storage tank 200 into the support ring 620 and place it on the top surface of the base 610 for easy loading and unloading.
