Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a chemical wastewater treatment device. Background Technique

[0002] Chemical wastewater treatment refers to the process of purifying wastewater from chemical production processes. These wastewaters usually contain various harmful substances and pollutants, such as organic matter, inorganic salts, heavy metals, acidic and alkaline substances, etc. If discharged into the environment without proper treatment, it will cause serious pollution to water bodies and may have negative impacts on the ecosystem and human health.

[0003] In the process of chemical wastewater treatment, when removing floating substances and suspended solids in the wastewater, the filter screen plate in the filtering device will gradually be blocked after long-term use, affecting the filtering efficiency. The traditional way of manually shutting down the machine to replace the filter screen plate is time-consuming and laborious, affecting the filtering efficiency. The Chinese utility model patent with the publication number CN221061903U discloses a chemical wastewater treatment device. By winding the filter screen on the unwinding reel, the extending end of the filter screen passes through two communication slots and is fixedly connected to the side wall of the winding reel. When too much impurities accumulate on the filter screen and affect the filtering effect of the filter screen, the winding reel will wind up the filter screen inside the treatment tank, and the unwinding reel will re-lay a new filter screen inside the treatment tank, thus completing the replacement of the filter screen. However, this solution has the following problems: when the filter screen is replaced, the impurities accumulated on the upper surface of the filter screen are intercepted by the guide shaft and still remain in the treatment tank. Even if a new filter screen is replaced, the remaining impurities will still affect the filtering effect. Summary of the Invention

[0004] The utility model aims to solve the deficiencies of the prior art and provides a chemical wastewater treatment device.

[0005] To achieve the above object, the utility model adopts the following technical solutions: A chemical wastewater treatment device includes a filtering tank.

On one side between the opposite surfaces of the replacement tank and the filtering tank, a first lead screw and a second lead screw are respectively rotatably connected. On the other side, guide rods corresponding to the first lead screw and the second lead screw are respectively fixedly connected. Moving blocks are respectively threadedly connected to the first lead screw and the second lead screw. Guide blocks are slidably sleeved on the guide rods. The tops of the moving blocks and the guide blocks are fixedly connected with a U-shaped support frame. Through holes are provided at the bottom inside the support frame. A filter screen plate is slidably inserted on the support frame. The front and rear sides of the filter screen plate are in sliding contact with the front and rear walls of the filtering tank. A sealed box cover is provided on the front side of the replacement tank. On the side of the replacement tank away from the filtering tank, a first motor for driving the first lead screw to rotate and a second motor for driving the second lead screw to rotate are respectively provided.

[0018] The present utility model will be further described below with reference to the accompanying drawings and embodiments:

[0019] As Figures 1 - 3 shown, a chemical wastewater treatment device includes a filtration tank 1. The top of the filtration tank 1 is provided with a water inlet 2, and a valve 17 is arranged on the water inlet 2. The bottom is provided with a water outlet 3. The bottom of the filtration tank 1 is provided with a conical head 4. The water outlet 3 is arranged at the bottom of the conical head 4. Several legs 5 are arranged at the bottom of the conical head 4.

[0020] One side of the filtration tank 1 is provided with a connected replacement tank 6. A first lead screw 7 and a second lead screw 8 are respectively rotatably connected between one side of the opposite surfaces of the replacement tank 6 and the filtration tank 1. On the other side, guide rods 9 corresponding to the first lead screw 7 and the second lead screw 8 are respectively fixedly connected. Moving blocks 10 are respectively threadedly connected to the first lead screw 7 and the second lead screw 8. Guide blocks are slidably sleeved on the guide rods 9. The tops of the moving blocks 10 and the guide blocks are fixedly connected with a U-shaped support frame 11. A through hole 12 is arranged at the inner bottom of the support frame 11. A filter screen plate 13 is slidably inserted on the support frame 11. First sliders 20 are arranged on both sides of the filter screen plate 13. First chutes corresponding to the first sliders 20 are arranged on the inner walls of both side plates of the support frame 11. The first sliders 20 are slidably inserted into the first chutes. The front and rear sides of the filter screen plate 13 are in sliding contact with the front and rear walls of the filtration tank 1. A second chute 21 is arranged on the front side of the moving block 10. Second sliders corresponding to the second chute 21 are arranged on the inner wall of the front side of the filtration tank 1. The second sliders are slidably arranged in the second chute 21.

[0021] A sealing box cover 14 is arranged on the front side of the replacement tank 6. A first motor 15 for driving the first lead screw 7 to rotate and a second motor 16 for driving the second lead screw 8 to rotate are respectively arranged on one side of the replacement tank 6 away from the filtration tank 1. Inclined guide plates 18 are correspondingly arranged on the inner walls of both sides of the filtration tank 1. The guide plates 18 are located above the replacement tank 6. Several reinforcing plates 19 are arranged between the bottom of the replacement tank 6 and the side wall of the filtration tank 1.

[0022] When the utility model works, start the first motor 15 to move the upper support frame 11 and the filter screen plate 13 into the filter box 1 and abut against the inner wall of the filter box 1. Open the valve 17, and the waste water enters the filter box 1 through the water inlet 2, filters impurities through the filter screen plate 13, and then is discharged through the water outlet 3. The setting of the flow guide plate 18 can prevent water from entering the replacement box 6. When the filter screen plate 13 needs to be replaced, first start the second motor 16 to move the lower support frame 11 and the filter screen plate 13 into the filter box 1, and then start the first motor 15 to move the corresponding support frame 11 into the replacement box 6. During this period, in order to prevent waste water from entering the replacement box 6, the opening size of the valve 17 can be controlled to reduce the water flow rate. After the filter screen plate 13 to be replaced enters the replacement box 6, open the sealed box cover 14, pull out the filter screen plate 13 from the support frame 11, and then insert a new filter screen plate 13, close the sealed box cover 14. In the waste water filtering section, the upper and lower filter screen plates 13 are used alternately to avoid blockage caused by long-term accumulation of impurities. The replacement operation of the filter screen plate 13 is convenient, does not require shutdown, and does not affect the filtering effect, and is flexible and convenient to use.
