Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a coating wastewater treatment device with a filtration structure. Background Technology

[0002] Painting wastewater treatment equipment is a key piece of equipment in the environmental protection field for purifying wastewater from painting production. It can treat wastewater generated from processes such as spray painting and electrophoresis, which contains pollutants such as heavy metals and organic matter. The equipment typically integrates multiple treatment processes, such as coagulation and sedimentation to remove suspended solids, biodegradation to decompose organic matter, and chemical precipitation to remove heavy metal ions. After treatment, the wastewater can meet discharge standards or be reused in production, effectively reducing environmental pollution and helping painting companies achieve green production. It is widely used in industries such as automobile manufacturing and furniture painting. However, existing painting wastewater treatment equipment still has certain problems in use:

[0003] For example, a coating wastewater filtration device with application number 202420953000.2 has the following technical solution: it includes a tank, a cover bolted to the upper end of the tank, a support base welded to the lower end of the tank, a water inlet pipe on the upper right side of the outer end of the tank, an oil drain pipe on the upper rear side of the outer end of the tank, a sewage drain pipe below the water inlet pipe, and a collection assembly connected to the rear flange of the sewage drain pipe. Through the tank, cover, and collection assembly, the entire process of wastewater treatment can be carried out in a sealed structure. However, existing coating wastewater treatment devices lack the function of adjusting the wastewater capacity in stages. The wastewater volume generated by different batches of coating operations fluctuates greatly, making it difficult for the device to adapt flexibly. On the other hand, the filter plate of the device is usually not removable. As the treatment process continues, a large amount of impurities will accumulate on the filter plate, affecting the filtration effect.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was implemented based on the existing coating wastewater treatment device. Utility Model Content

[0006] The purpose of this invention is to provide a coating wastewater treatment device with a filtration structure to solve the problems mentioned in the background art, such as the difficulty in adapting to different wastewater volumes for treatment and the impact of non-removable filter plates on filtration efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A coating wastewater treatment device with a filtration structure includes a water storage tank shell. A sedimentation tank is located on the right side of the water storage tank shell, and an outlet is located on the right side of the sedimentation tank. The flow rate of the outlet is controlled by a regulating valve. A groove is formed on the left edge of the water storage tank shell, and several support plates are provided on the upper surface edge of the water storage tank shell.

[0009] Preferably, the inner front and rear sides of the water storage tank shell are provided with several slots, and the water baffle is snapped into the slots to form a separation structure for the water storage capacity inside the water storage tank shell.

[0010] By adopting the above technical solution, the slots and baffles inside the outer shell of the water storage tank are designed so that the baffles are snapped into the slots. This allows for flexible adjustment of the water storage space in the water storage tank according to the actual wastewater volume, enabling graded treatment of different wastewater volumes and improving the adaptability of the device to fluctuations in wastewater volume.

[0011] Preferably, a first drive motor is fixedly installed inside the groove, and a pulley assembly is connected above the output end of the first drive motor, and a first rotating rod is connected and installed above the pulley assembly.

[0014] By adopting the above technical solution, the first bevel gear on the first rotating rod and the second bevel gear meshing with it change the direction of power transmission through gear transmission, converting the rotation of the first rotating rod into the rotation of the threaded rod, providing a power basis for the left and right movement of the moving frame and the filter plate.

[0015] Preferably, a threaded rod is connected and installed on the right side of each of the second bevel gears, and a movable frame is threadedly connected to the outside of the threaded rod, and the movable frame is located above the outer shell of the water storage tank to form a left and right movable structure.

[0016] With the above technical solution, the threaded rod is threadedly connected to the movable frame. When the threaded rod is rotated, the movable frame can move smoothly left and right above the outer shell of the water storage tank, thereby driving the filter plate to move, which makes it easy to adjust the position of the filter plate and meet different filtration needs.

[0017] Preferably, a filter plate is connected and installed below the movable frame, and the filter plate is fixed to the movable frame by bolts.

[0018] Using the above technical solution, the movable frame and the filter plate are connected by bolts. This connection method makes the filter plate easy to disassemble and install. When impurities accumulate on the filter plate and affect the filtration effect, it can be easily disassembled for cleaning or replacement, ensuring the filtration performance of the device.

[0019] Preferably, a second drive motor is fixedly installed above the top plate, and a second rotating rod is connected to the output end below the second drive motor, and several stirring rods are fixedly connected to the outer side below the second rotating rod.

[0020] Using the above technical solution, the second drive motor, the second rotating rod, and the stirring rod are located above the top plate. The second drive motor drives the second rotating rod and the stirring rod to rotate, which stirs the wastewater in the sedimentation tank, accelerates the sedimentation and separation of pollutants in the wastewater, and improves the wastewater treatment efficiency.

[0023] 2. High-efficiency filtration and easy maintenance: The threaded connection between the threaded rod and the movable frame allows the movable frame to move smoothly left and right above the outer shell of the water storage tank when the threaded rod is rotated, thereby moving the filter plate. This makes it easy to adjust the position of the filter plate. Furthermore, the connection between the filter plate and the movable frame via bolts facilitates disassembly, ensuring a good filtration effect and making it convenient to clean and replace the filter plate.
