Description

Technical Field

[0001] This utility model relates to the field of acid pickling technology, and in particular to an acid pickling and deoxidation device. Background Technology

[0002] Pickling and deoxidation equipment is a specialized device that removes the oxide layer from the metal surface through a chemical reaction between the pickling solution and the oxide layer, combined with mechanical assistance. Its core equipment includes a pickling tank for holding the pickling solution, an acid pump for transporting and circulating the pickling solution, an acid mist absorption tower for collecting and treating acid mist to protect the environment and personnel safety, a filtration device for filtering impurities in the pickling solution and extending the service life of the acid solution, a heating device to meet specific temperature process requirements, an automated control system for automatically monitoring and controlling parameters such as temperature, concentration, and liquid level, and an ultrasonic cleaning device that uses the ultrasonic cavitation effect to improve pickling efficiency.

[0003] The existing utility model patent with publication number CN218812107U discloses a high-performance stainless steel pickling equipment. This equipment first places the stainless steel workpiece into a pickling basket for pickling and passivation treatment. Then, a cleaning and stirring mechanism agitates the pickling solution. After the pickling and passivation treatment is complete, a first motor is activated, causing the pickling basket on the connecting plate to rotate via a first rotating rod. When the basket rotates to a certain angle, the stainless steel workpiece falls into the cleaning basket due to its own weight. A water pump is then activated to draw water from a water tank. The water is then sprayed through water pipes and an outlet pipe from a high-pressure spray nozzle to rinse and clean the surface of the stainless steel workpiece. After cleaning, the turntable rotates, causing the outlet pipe to move the high-pressure spray nozzle to the outside of the rinsing tank. Finally, the cleaning basket is removed from the rinsing tank using a handle. To facilitate the processing of stainless steel workpieces, this stainless steel pickling equipment avoids the problem of needing to remove the workpieces after pickling and passivation before rinsing, thus improving the efficiency of the equipment. While solving the problem of "traditional stainless steel pickling equipment requiring the removal of workpieces after pickling and passivation in the pickling tank, followed by rinsing with pickling solution, a time-consuming, labor-intensive, and inefficient method," the equipment also addresses the issue of surface obstruction caused by the accumulation of cleaning components in the cleaning basket. This obstructs the high-pressure water jets from reaching all areas, especially gaps, grooves, or overlapping parts of the workpieces, where residual pickling solution or oxide scale fragments may remain, affecting the cleaning effect. Therefore, this pickling and deoxidation equipment is proposed. Utility Model Content

[0004] Therefore, it is necessary to provide an acid washing and deoxidation device to address the aforementioned technical problems.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution to the problem that the cleaning components accumulate in the cleaning basket after being poured into it, thus affecting the cleaning effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An acid pickling and deoxidation device, comprising:

[0008] A pickling tank, wherein a partition plate is fixedly connected to the inner wall of the pickling tank, a mesh is provided on one side of the inner cavity of the pickling tank, and a flipping device is installed on the top of the partition plate;

[0009] A drive unit 1 is located on the other side of the pickling tank cavity. A material tray and a cleaning cylinder are provided on the top of the drive unit 1. A top ball is movably embedded in the center of the bottom end of the material tray. A rotating rod is fixedly connected to the bottom end of the top ball. A side rod is fixedly connected to one side wall of the rotating rod. A sliding ball is fixedly connected to one end of the side rod.

[0010] In a preferred embodiment of the pickling and deoxidation equipment provided by this utility model, the partition plate is placed in the middle of the pickling tank cavity, dividing it into two chambers, and the net is connected to the turning device via transmission.

[0011] In a preferred embodiment of the pickling and deoxidation equipment provided by this utility model, the surfaces of the material tray and the cleaning cylinder are provided with several through holes, and the material tray is designed to be inclined.

[0012] In a preferred embodiment of the pickling and deoxidation equipment provided by this utility model, side plates are fixedly connected to both sides of the top of the material tray, and the cleaning cylinder is placed between the two side plates.

[0013] In a preferred embodiment of the pickling and deoxidation equipment provided by this utility model, an annular groove is provided at the bottom of the material tray, and the annular groove is slidably connected to the sliding ball.

[0014] In a preferred embodiment of the pickling and deoxidation equipment provided by this utility model, the drive unit is specifically a motor, and the bottom end of the rotating rod is connected to the output shaft of the drive unit.

[0015] In a preferred embodiment of the pickling and deoxidation equipment provided by this utility model, a guide plate is provided on one side of the flipping device, and a drive unit is installed on the top of one side wall of the pickling tank.

[0016] In a preferred embodiment of the pickling and deoxidation equipment provided by this utility model, the output shaft of the second drive unit rotates through the surface of the pickling tank to its inner cavity and is connected to a connecting rod. One end of the connecting rod is fixedly inserted through one side of the guide plate and rotates to connect with the inner wall of the pickling tank.

[0018] In a preferred embodiment of the pickling and deoxidation equipment provided by this utility model, a water-proof shell is fixedly connected to one side of the bottom of the inner wall of the pickling tank, and the drive unit is installed in the inner cavity of the water-proof shell.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model provides an acid pickling and deoxidation device. When the workpiece is acid-washed and enters the cleaning cylinder for cleaning, the drive unit rotates the side rod, causing the sliding ball to rotate in the annular groove. This causes the material tray to continuously change its tilt state, which in turn causes the material tray to move the cleaning cylinder and the workpiece inside it. This allows the workpiece to continuously change its posture within the cleaning cylinder, avoiding dead corners caused by static accumulation and ensuring that the rinsing water can contact all surfaces of the workpiece, thus improving the cleaning efficiency of the workpiece.

[0021] The present invention provides an acid pickling and deoxidation device, which, by setting a guide plate, allows the falling workpieces to smoothly enter the cleaning cylinder for subsequent cleaning when the flipping device drives the net to flip to one side to dump the material. Then, the second drive unit is used to make the guide plate rotate upward to avoid interfering with the subsequent shaking of the cleaning cylinder. Attached Figure Description

Example

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A pickling and deoxidation device includes a pickling tank 1, a partition plate 2 fixedly connected to the inner wall of the pickling tank 1, a mesh 3 provided on one side of the inner cavity of the pickling tank 1 to carry the workpiece to be pickled, and a turning device 4 to realize the unloading after pickling. The top of the partition plate 2 is equipped with a turning device 4 to drive the mesh 3 to turn over and realize the transfer of the workpiece to the cleaning cylinder 7 after pickling.

[0033] Drive unit 5 provides a power source to realize the dynamic shaking of the workpiece during the cleaning stage, avoiding dead corners of accumulation. Drive unit 5 is located on the other side of the inner cavity of pickling tank 1. The top of drive unit 5 is equipped with a material tray 6 and a cleaning cylinder 7 to accommodate the workpiece during the cleaning stage. It works in conjunction with the shaking of the material tray 6 to achieve all-round cleaning. The tilting design and shaking mechanism drive the movement of the workpiece. A top ball 11 is movably embedded in the center of the bottom end of the material tray 6 to support the material tray 6 and reduce the frictional resistance between it and the rotating rod 9, ensuring that the material tray 6 can rotate and shake flexibly. The bottom end of the top ball 11 is fixedly connected to the rotating rod 9. A side rod 16 is fixedly connected to one side wall of the rotating rod 9. The side rod 16 has an L-shaped design. A sliding ball 17 is fixedly connected to one end of the side rod 16, which converts the rotational motion of the rotating rod 9 into the circular motion of the sliding ball 17 in the annular groove 10, so that the material tray 6 will have a shaking tendency.

[0034] Preferably, the partition plate 2 is placed in the middle of the inner cavity of the pickling tank 1, dividing it into two chambers, one for pickling and the other for cleaning. The net 3 is connected to the turning device 4. The surfaces of the material tray 6 and the cleaning cylinder 7 are provided with several through holes 8. The material tray 6 is designed to be inclined, using gravity to guide the workpiece to slide, and the shaking is used to achieve posture change, thereby improving the uniformity of cleaning.

[0035] Preferably, side plates 12 are fixedly connected to both sides of the top of the material tray 6, the cleaning cylinder 7 is placed between the two side plates 12, and a water-proof shell 18 is fixedly connected to one side of the bottom of the inner wall of the pickling tank 1 to isolate the liquid at the bottom of the pickling tank 1, prevent the motor from getting damp or corroded, and extend the service life of the equipment. The drive unit 5 is installed in the inner cavity of the water-proof shell 18.

[0036] Preferably, the bottom end of the material tray 6 is provided with an annular groove 10, which is slidably connected to the sliding ball 17. The drive unit 5 is specifically a motor, and the bottom end of the rotating rod 9 is connected to the output shaft of the drive unit 5 for transmission.

[0037] Preferably, a guide plate 13 is provided on one side of the flipping device 4 to guide the workpiece tilted by the net 3 to fall accurately into the cleaning cylinder 7. A second drive unit 14 is installed on the top of one side wall of the pickling tank 1. The output shaft of the second drive unit 14 rotates through the surface of the pickling tank 1 to its inner cavity and is connected to a connecting rod 15. One end of the connecting rod 15 is fixed through one side of the guide plate 13 and rotates to be connected to the inner wall of the pickling tank 1. The guide plate 13 is placed on the top of the cleaning cylinder 7. The second drive unit 14 is specifically a motor.

[0038] The operation process of the pickling and deoxidation equipment provided by this utility model is as follows: The workpiece to be treated is placed in the mesh 3 on one side of the inner cavity of the pickling tank 1. The oxide layer is removed in the pickling chamber by the pickling solution. After pickling, the flipping device 4 drives the mesh 3 to flip to one side of the guide plate 13. The workpiece slides down the inclined surface of the guide plate 13 into the cleaning cylinder 7 in the cleaning chamber on the other side. At this time, the second drive unit 14 drives the connecting rod 15 to flip the guide plate 13 upward and reset it to avoid interfering with the subsequent cleaning process. Then the first drive unit 5 is started, and its output shaft drives the side rod 16 and the sliding rod 16 through the rotating rod 9. The moving ball 17 rotates, and the sliding ball 17 makes an eccentric circular motion in the annular groove 10 at the bottom of the material tray 6, which forces the tilted material tray 6 to drive the cleaning cylinder 7 to produce regular shaking, so that the workpiece continuously changes its posture in the cleaning cylinder 7. In conjunction with the through holes 8 on the surface of the material tray 6 and the cleaning cylinder 7, the cleaning fluid is promoted to flow, and all-round rinsing is achieved. During the process, the top ball 11 reduces the frictional resistance between the material tray 6 and the rotating rod 9, the side plate 12 restricts the displacement of the cleaning cylinder 7 to ensure the stability of the shaking, and the water-proof shell 18 isolates the drive unit 5 from the liquid to ensure the safe operation of the equipment, and finally completes the efficient cleaning after pickling.
