[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] The purpose of this invention is to provide a waste acid filter with backwashing function to solve the problems existing in the prior art. It has a simple structure, is easy to use, and effectively improves work efficiency.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] This utility model provides a waste acid filter with backwashing function, such as Figure 1 As shown, the filter includes: a filter body 1, a first input pipe 2, a first valve 3, an output pipe 4, a second valve 5, a compressed air pipe 6, a third valve 7, an exhaust pipe 8, and a fourth valve 9. The filter body 1 has a first inlet, a second inlet, a first outlet, and a second outlet. The first input pipe 2 is connected to the first input pipe 2. The first valve 3 is located on the first input pipe 2. The output pipe 4 is connected to the first outlet. The second valve 5 is located on the output pipe 4. One end of the compressed air pipe 6 is connected to the second inlet, and the other end is connected to a compressed air source. The third valve 7 is located on the compressed air pipe 6. The exhaust pipe 8 is connected to the second outlet. The fourth valve 9 is located on the exhaust pipe 8. By setting up multiple pipes and valves, a normal filtration process can be achieved, and the basic framework for subsequent backwashing operations can be provided. The components work together to ensure that the filter can effectively treat waste acid and can be maintained when clogged.

[0020] In a preferred embodiment, the waste acid filter with backwashing function further includes a second input pipe 10 and a fifth valve 11. The second input pipe 10 is connected to the second inlet, and the fifth valve 11 is disposed on the second input pipe 10. The compressed air pipe 6 is connected to the second input pipe 10 between the fifth valve 11 and the second inlet. The addition of the second input pipe 10 and the fifth valve 11 provides more options for the operation and maintenance of the filter. When needed, other necessary media can be introduced from this pipe for maintenance or other operations, such as adding cleaning fluid. At the same time, the compressed air pipe 6 is connected at this position, which helps to more flexibly control the backwashing media input and pressure parameters under specific conditions, thereby enhancing the backwashing effect and operability.

[0021] In a preferred embodiment, the waste acid filter with backwashing function further includes a bypass pipe 12 and a sixth valve 13. One end of the bypass pipe 12 is connected to the first input pipe 2 on the side of the first valve 3 away from the first inlet, and the other end is connected to the output pipe 4 on the side of the second valve 5 away from the first outlet. The sixth valve 13 is disposed on the bypass pipe 12. The bypass pipe 12 and the sixth valve 13 enable the waste acid to bypass the filter body 1 and continue to be transported when the filter body 1 needs maintenance, repair or emergency. This ensures the continuous operation of the entire waste acid treatment system and reduces the impact of filter maintenance on the production process.

[0022] In a preferred embodiment, the waste acid filter with backwashing function further includes a seventh valve 14. The seventh valve 14 is located on the side away from the first valve 3 at the connection position between the bypass pipe 12 and the first input pipe 2. The seventh valve 14 further increases the accuracy of flow and direction control at the connection between the bypass pipe 12 and the main pipe, and can better regulate the fluid volume and flow state in the bypass pipe 12, ensuring that the system pressure and other parameters remain stable when the bypass pipe 12 is activated, thereby improving the overall stability and reliability of the system.

[0023] In a preferred embodiment, the drain pipe 8 is connected to the bottom of the filter body 1. The connection between the drain pipe 8 and the bottom of the filter body 1 allows heavier impurities and foreign objects accumulated at the bottom of the filter to be discharged more effectively during backwashing or draining operations, thereby improving the thoroughness of the internal cleaning of the filter and helping to restore the filter's filtration performance.

[0024] In a preferred embodiment, the first valve 3, the second valve 5, the third valve 7, the fourth valve 9, the fifth valve 11, the sixth valve 13, and the seventh valve 14 are all solenoid valves. Using solenoid valves enables automated control, which facilitates the integration of automated control programs into the entire waste acid treatment system. Operators can remotely control the opening and closing of each valve and adjust parameters such as flow rate, improving the convenience of operation. At the same time, solenoid valves have a fast response speed and can execute corresponding actions more promptly and accurately, enhancing the system's operating efficiency and control precision.
