Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipe pickling, in particular to a stainless steel pipe pickling device. Background Art

[0002] Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines and mechanical structural parts such as petroleum, chemical, medical, food, light industry, mechanical instruments, etc. In addition, when the bending and torsional strengths are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used in furniture and kitchen utensils. In order to remove the oxide scale and welding slag on the surface of stainless steel pipe, the stainless steel pipe is pickled.

[0003] The existing pickling device only puts the stainless steel pipe into the pickling liquid to soak it, and then cleans its surface, but cannot clean its inner wall, which leads to the problem of incomplete pickling of the stainless steel pipe. Summary of the invention

[0007] The scrubbing mechanism comprises a driving motor 1, an output end of the driving motor 1 is fixedly connected with a hollow rod, and a surface of the hollow rod is fixedly connected with cleaning bristles.

[0008] A further improvement of the technical solution of the utility model is that a water leakage hole is opened on the surface of the hollow rod, a cleaning sponge is fixedly connected to the inside of the water leakage hole, a soft pad is sleeved on the outside of the hollow rod, and the bottom of the stainless steel pipe is located on the soft pad, thereby preventing the stainless steel pipe from causing damage to the inside of the pickling box.

[0009] A further improvement of the technical solution of the utility model is that: the shell mechanism includes a pickling box, the bottom of the pickling box is fixedly connected to the top of the driving motor, the inner bottom surface of the pickling box is fixedly connected to the lower surface of the cushion, the bottom of the pickling box is sleeved on the bottom of the hollow rod, the top inner wall of the pickling box is fixedly connected to a support plate with holes, the upper surface of the support plate with holes is fixedly connected to a double-layer support frame, and the wiped-off oxide scale, welding slag and pickling liquid can fall into the pickling box through the support plate with holes, thereby reducing the difficulty of subsequent cleaning.

[0010] A further improvement of the technical solution of the utility model is that a baffle is fixedly connected to the top of the pickling box, an electric push rod is fixedly connected to the inner side of the baffle, the telescopic end of the electric push rod is fixedly connected to an arc-shaped support plate, and a wiping cloth is fixedly connected to the inner wall of the arc-shaped support plate. The wiping cloth can wipe the surface of the stainless steel pipe, thereby improving the pickling quality.

[0011] A further improvement of the technical solution of the utility model is that the clamping mechanism includes a second drive motor, the bottom of the second drive motor is fixedly connected to the upper surface of the double-layer support frame, the output end of the second drive motor is fixedly connected to a paddle, and the second drive motor runs to achieve the effect of driving the paddle to rotate.

[0012] A further improvement of the technical solution of the utility model is that: the outer surface of the paddle is transmission-connected with a hollow plate, the hollow plate is sleeved inside the double-layer support frame, and the bottom of the hollow plate is fixedly connected with an electric push rod 2. Every time the paddle rotates one circle, the hollow plate can be moved once, thereby driving the hollow plate to rotate.

Then, the drive motor 11 is started to drive the hollow rod 12 to rotate, and the cleaning bristles 13 and the cleaning sponge 15 on its surface rotate accordingly. The pickling liquid enters the hollow rod 12 through the opening at the top of the hollow rod 12, and then flows into the cleaning sponge 15 and the inner wall of the stainless steel pipe through the leakage hole 14. At the same time, the outer surface of the stainless steel pipe is soaked in the pickling liquid, and then the cleaning bristles 13 and the cleaning sponge 15 rotate, which can remove the oxide scale and welding slag on the inner wall, thereby improving the pickling effect.

[0026] Specifically, the pickling liquid is poured into the hollow part in the middle of the support plate 22 with holes to pickle the stainless steel pipe. After the pickling is completed, the stainless steel pipe is clamped out of the pickling box 21 by the clamping mechanism 3, and then the electric push rods 24 on both sides are started to change the distance between the two sets of arc-shaped support plates 25 and the wiping cloth 26, so that the wiping cloth 26 is in contact with the outer surface of the stainless steel pipe.
