Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment and processing technology, specifically to an automatic dosing device for water treatment agents in a large-scale wastewater treatment plant. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, urban landscaping, medical care, and catering. Common wastewater treatment methods require corresponding chemicals to be mixed with the wastewater for processing. Therefore, automatic dosing devices for water treatment agents are used to prepare the chemicals.

[0003] However, when automatic water treatment agent dosing devices are put into use, the required agents and water are mixed in a mixing tank using a stirring rod. Currently, most devices have a relatively unidirectional stirring rod, which can cause agent particles to form certain movement trajectories and accumulation patterns during mixing. These fixed patterns slow down the diffusion rate of the agent in the water, resulting in a slower mixing rate. Furthermore, after most of the agent and water are mixed in the mixing tank, workers need to clean the inside of the tank. Some residue from the agent-water mixture adheres to the inner wall of the mixing tank, making cleaning inconvenient and increasing the workload for workers. Utility Model Content

[0004] The purpose of this invention is to provide an automatic dosing device for water treatment agents in large-scale sewage treatment plants, so as to solve the problems mentioned in the background art.

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.

[0021] Please see Figure 1-5As shown, an automatic dosing device for water treatment agents in a large-scale wastewater treatment plant includes a support base 1, which supports the device and enables it to operate. A mixing tank 2 is bolted to the top of the support base 1, and a feeding port 3 is connected to the top of the mixing tank 2, allowing operators to add the dosing materials into the mixing tank 2. A controller 4 is installed on the top of the support base 1, and the controller 4 has multiple display buttons on its surface, facilitating operator control of the device. A discharge assembly 5 is located at the bottom of the mixing tank 2, consisting of a water pump and a drain pipe, which discharges the processed materials from the mixing tank 2. A stepper motor 6 is bolted to the top of the mixing tank 2, and a rotating rod 7 is fixedly connected to the output shaft of the stepper motor 6. A rotating block 8 is fixedly connected to the bottom of the rotating rod 7, allowing the stepper motor 6 to drive the rotating rod 7 to rotate the mixing tank 2. The inner cavity of the mixing tank 2 rotates. A rotating mechanism 9 is provided on one side of the rotating rod 7. A stirring rod 10 is rotatably connected to the top of the rotating block 8. The stirring rod 10 and the rotating mechanism 9 work together. With the cooperation of the rotating rod 7 and the rotating block 8, the rotating mechanism 9 can drive multiple stirring rods 10 to rotate in the inner cavity of the mixing tank 2. At the same time, the stirring rods 10 can rotate on their own axis in the inner cavity of the mixing tank 2, thereby increasing the mixing rate of the stirring rods 10 on the prepared materials. A guiding mechanism 11 is provided in the inner cavity of the mixing tank 2. Under the action of the guiding mechanism 11, the positional deviation of the rotating block 8 during operation is effectively reduced, and the stability of the rotating block 8 is increased, thereby improving the stability of the device. A cleaning mechanism 12 is provided on one side of the rotating rod 7. With the cooperation of the stepper motor 6 and the rotating rod 7, the cleaning mechanism 12 can clean the inner wall of the mixing tank 2, making it convenient for workers to clean the mixing tank 2, thereby reducing the workload of workers.

[0022] The rotating mechanism 9 includes a first spur gear 91, the inner cavity of which is fixedly connected to the surface of the rotating rod 7. A mounting block 92 is fixedly connected to the surface of the rotating rod 7. A second spur gear 93 is rotatably connected to the bottom of the mounting block 92. The bottom of the second spur gear 93 is fixedly connected to the top of the stirring rod 10. The surface of the second spur gear 93 meshes with the surface of the first spur gear 91. With the cooperation of the stepper motor 6 and the rotating rod 7, the first spur gear 91 can rotate, and the mounting block 92 can drive the second spur gear 93 to rotate within the inner cavity of the mixing tank 2. Simultaneously, under the meshing action of the first spur gear 91 and the second spur gear 93, the mounting block 92 can drive the stirring rod 10 to rotate through the second spur gear 93, thereby causing the stirring rod 10 to rotate within the inner cavity of the mixing tank 2. At the same time, the stirring rod 10 rotates on its own axis within the inner cavity of the mixing tank 2, thereby improving the mixing efficiency of the device for dispensing materials.

[0023] The guiding mechanism 11 includes a fixed block 111. The bottom of the fixed block 111 is fixedly connected to the bottom of the inner cavity of the mixing tank 2. A guide groove 112 is provided on the top of the fixed block 111. A guide block 113 is slidably connected to the inner cavity of the guide groove 112. The top of the guide block 113 is fixedly connected to the bottom of the rotating block 8. Under the action of the rotating block 8, the guide block 113 can rotate in the inner cavity of the guide groove 112. With the cooperation of the fixed block 111, the positional deviation of the rotating block 8 during rotation is effectively reduced, thereby improving the stability of the device.

[0024] The cleaning mechanism 12 includes a connecting rod 121. One end of the connecting rod 121 is fixedly connected to the surface of the rotating rod 7, and the other end of the connecting rod 121 is fixedly connected to a connecting plate 122. A cleaning pad 123 is fixedly connected to the other side of the connecting plate 122. The surface of the cleaning pad 123 is slidably connected to the inner wall of the mixing tank 2. With the cooperation of the stepper motor 6 and the rotating rod 7, the connecting rod 121 can drive the cleaning pad 123 to rotate in the inner cavity of the mixing tank 2 through the connecting plate 122, so that the cleaning pad 123 cleans the inner wall of the mixing tank 2, which makes it convenient for the staff to clean the mixing tank 2 and reduces the workload of the staff. A connecting block 13 is fixedly connected to the bottom of the connecting plate 122, and the other side of the connecting block 13 is fixedly connected to one side of the rotating block 8. Under the action of the connecting block 13, the stability of the connecting plate 122 during rotation is increased.

[0025] Working principle: First, the operator adds the medicine materials into the mixing tank 2 through the feeding port 3. Under the action of the stepper motor 6, the rotating rod 7 drives the rotating block 8 to rotate in the inner cavity of the mixing tank 2. At the same time, the rotating rod 7 drives the first spur gear 91 to rotate, and the rotating rod 7 drives the second spur gear 93 to rotate in the inner cavity of the mixing tank 2 through the mounting block 92. Under the mutual meshing of the first spur gear 91 and the second spur gear 93, the mixing rod 10 can rotate on its own axis. Meanwhile, the rotating block 8 rotates in the inner cavity of the guide groove 112 through the guide block 113. With the cooperation of the fixing block 111, the rotation of the rotating block 8 can be made more stable. Then, the processed material is discharged through the discharge assembly 5. When the operator needs to clean the inner cavity of the mixing tank 2, the rotating rod 7 drives the connecting plate 122 through the connecting rod 121 to drive the cleaning pad 123 to rotate in the inner cavity of the mixing tank 2, so that the cleaning pad 123 cleans the inner wall of the mixing tank 2. Then, the cleaned water is discharged from the discharge assembly 5.
