Description

Technical Field

[0001] This utility model relates to the technical field of negative pressure pipe raw material processing, specifically to an acid washing device for processing negative pressure pipe raw materials. Background Technology

[0002] A negative pressure pipe is a device that can alter the pressure distribution inside a pipeline. It typically consists of a pipe and a negative pressure device. The pipe is open to air at both ends, and the negative pressure device is installed at one of its ports. When the negative pressure device operates, a negative pressure is generated inside the pipe, thus changing the pressure distribution of the fluid within the pipe. Negative pressure pipes are mainly used for fluid control in pipelines and have many applications; for example, vacuum cleaners commonly utilize the principle of negative pressure pipes. The pipe material is generally metal, and metal pipes (such as stainless steel and carbon steel) are prone to oxide scale, oil stains, and rust layers, requiring acid pickling treatment of the negative pressure pipe material.

[0003] Existing pickling equipment suffers from problems such as low efficiency, significant acid waste, and incomplete waste gas treatment, which increase processing costs and cause environmental pollution. To address these issues, existing equipment needs to be improved. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an acid pickling device for processing negative pressure pipe raw materials, based on... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, side seats 2 are symmetrically arranged on both sides of the pickling tank 1, and electric telescopic rods 3 are symmetrically arranged on the upper end of the side seats 2. The output end of the electric telescopic rods 3 is connected to the lower end of the sealing cover 4. The electric telescopic rods 3 drive the sealing cover 4 to rise and fall, which facilitates the synchronous rise and fall of the negative pressure tube material placed inside the placement frame 7. This allows the negative pressure tube material to enter the pickling tank 1 while the sealing cover 4 seals the top of the pickling tank 1. The bottom of the first connecting rod 6 symmetrically arranged on one side of the lower end of the sealing cover 4 is rotatably connected to one side of the upper end of the placement frame 7. The other side of the upper end of the placement frame 7 is connected to the bottom of the symmetrically arranged second connecting rod 8. At the same time, the top of the second connecting rod 8 passes through the sealing box cover 4 and is connected to the lower end of one side of the horizontal plate 9. The other side of the lower end of the horizontal plate 9 is connected to the upper end of the sealing box cover 4 through the electric push rod 10. The electric push rod 10 pushes the horizontal plate 9 to move upward, so that the horizontal plate 9 drives the second connecting rod 8 and one side of the placement frame 7 to move upward. Meanwhile, the other side of the placement frame 7 rotates at the lower end of the first connecting rod 6, causing the placement frame 7 to tilt, thereby causing the negative pressure pipe material to tilt and discharge the pickling liquid inside.

[0022] To further explain, a rubber pad 5 is provided at the bottom of the lower end of the sealing box cover 4, and the size of the rubber pad 5 is the same as that of the pickling box 1. At the same time, the position of the rubber pad 5 corresponds to the position of the pickling box 1. The rubber pad 5 is located outside the spray device 12. The rubber pad 5 seals the gap between the sealing box cover 4 and the pickling box 1, preventing the exhaust gas generated during pickling from overflowing through the gap and improving the sealing performance.

[0023] To further explain, the placement frame 7 has an open structure on the side near the second connecting rod 8, and multiple drain ports 701 are equidistantly provided on the side of the placement frame 7 near the first connecting rod 6. Through the drain ports 701, the pickling solution is not easily accumulated inside the placement frame 7, so that the raw material of the negative pressure tube after pickling can be dried quickly. At the same time, positioning blocks 702 are symmetrically arranged on the top of the side of the placement frame 7 near the first connecting rod 6, and a crossbar 703 is arranged between the two positioning blocks 702. The crossbar 703 is movably connected to the lower end of the first connecting rod 6. A locking seat 704 is symmetrically arranged on the top of the side of the placement frame 7 near the second connecting rod 8, and the inner side of the upper end of the locking seat 704 is connected to the lower end of the second connecting rod 8.

[0024] according to Figure 1 , Figure 3 and Figure 4As shown, a spray device 12 is installed in the middle of the lower end of the sealed box cover 4, and the top of the spray device 12 is connected to the bottom of the back of the pickling box 1 through a conveying pipe 11. At the same time, a conveying pump 13 is installed on the conveying pipe 11. The conveying pump 13 is specifically an acid-resistant pump, so that it is not easy to damage the conveying pump 13 when conveying pickling solution, thus improving the practicality of use. A filter partition plate 14 is installed at the bottom of the inside of the pickling box 1. The filter partition plate 14 facilitates the filtration of impurities in the pickling liquid, so that the pickling solution at the bottom of the inside of the pickling box 1 can be reused, improving the utilization rate. A slag removal filter assembly is installed on one side of the pickling box 1 at one end of the filter partition plate 14. The slag removal filter assembly includes a slag pump 15, a connecting pipe 16, and a filter box 17. The two ends of the slag pump 15 are connected to the pickling box 1 and the connecting pipe 16 respectively, and the other end of the connecting pipe 16 is connected to the filter box 17. The bottom of the filter box 17 is... A slag discharge valve 18 is provided on one side of the filter box 17, and a return pipe 19 is provided on the other side of the filter box 17 and connected to the lower front end of the pickling box 1. At the same time, a one-way valve 20 is provided on the return pipe 19. The impurities and pickling liquid on the filter partition plate 14 are transported to the filter box 17 through the connecting pipe 16 by the slag pump 15. After filtration, they are transported to the pickling box 1 for reuse through the return pipe 19 and the one-way valve 20. The slag discharge valve 18 facilitates the discharge of the filtered impurities. A waste gas treatment component is provided on one side of the top of the sealed box cover 4. The waste gas treatment component includes a vent valve 23, an exhaust pipe 24 and a purifier 25. The vent valve 23 is threadedly connected to the exhaust pipe 24, and the purifier 25 is provided on the exhaust pipe 24. The purifier 25 is a prior art technology. The waste gas generated by pickling is discharged through the vent valve 23, and then the waste gas enters the purifier 25 through the exhaust pipe 24 before being discharged, which improves the environmental protection of the use.

[0025] To further explain, a blower 21 is installed on the rear side of the pickling tank 1 above the filter partition plate 14, and multiple air inlets 22 are equidistantly arranged on the inner side of the pickling tank 1 by the blower 21. External gas is delivered into the pickling tank 1 through the air inlets 22 by the blower 21, so that the pickling solution stored in the pickling tank 1 flows, so that the pickling solution is in full contact with the raw material of the negative pressure pipe, thereby improving the pickling effect and efficiency.
