Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe degreasing, in particular to a blowing and pre-degreasing device for the production of seamless stainless steel pipes. Background Art

[0002] Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. In addition, when the bending and torsional strengths are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used as furniture and kitchen utensils. In the process of stainless steel pipe processing, the grease on the surface needs to be cleaned, so the stainless steel pipe blowing and pre-degreasing device needs to be used.

[0003] At present, most of the pre-degreasing devices for stainless steel pipes use an immersion method to degrease the grease on their surface. This method requires the steel pipe to be immersed for a long time before it can be completely degreased. When the steel pipes are stacked together, some areas of the steel pipes will be in close contact, making it difficult to degrease the closely contacted parts well. Not only is the degreasing efficiency low, but the degreasing is also not ideal.

[0004] Therefore, it is very necessary to invent a purge pre-degreasing device for producing seamless stainless steel pipes. Utility Model Content

[0006] The wave maker includes a fixed shaft, a rotating drum, a wave making plate, a limiting guide plate, a rotating toggle body and a rotating shaft. The fixed shaft is fixedly installed inside a pre-degreasing container box. The rotating drum is rotatably installed on the fixed shaft. The wave making plate is correspondingly fixedly installed on the rotating drum. A limiting guide plate is arranged between the wave making plates.

[0007] Preferably, the pre-degreasing container box includes a degreasing box, a box cover, a placement shaft and a driving motor. The degreasing box is provided with a box cover that is rotatably installed thereon, and a plurality of the placement shafts are rotatably installed inside the degreasing box. The output end of the driving motor rotates through the degreasing box and is fixedly connected to the other end of the rotating shaft. The number of driving motors is the same as the number of wave makers.

[0008] Preferably, there is a spacing between the placement axes that does not allow the steel pipes and joints to fall, and a wave maker is provided below the placement axes.

[0009] Preferably, the two wave making plates are arranged in an "eight" shape, and the limiting guide plate arranged inside the wave making plate is a "U" shaped structure.

[0010] Preferably, the rotating toggle body is an 'L' shaped structure as a whole, and is composed of a roller and an arc plate.

[0020] As attached Figure 1 To Attachment Figure 3 As shown:

[0021] The utility model provides a blowing and pre-degreasing device for the production of seamless stainless steel pipes, comprising a pre-degreasing container box 1 and a wave maker 2, at least two of the wave makers 2 are installed inside the pre-degreasing container box 1, and there is a spacing between the wave makers 2 to allow swinging motion, and a large amount of degreasing liquid is contained inside the pre-degreasing container box 1.

[0022] The wave maker 2 includes a fixed shaft 21, a rotating drum 22, a wave making plate 23, a limiting guide plate 24, a rotating toggle body 25 and a rotating shaft 26. The fixed shaft 21 is fixedly installed inside the pre-degreasing container box 1. The rotating drum 22 is rotatably installed on the fixed shaft 21, and the wave making plate 23 is correspondingly fixedly installed on the rotating drum 22. A limiting guide plate 24 is arranged between the wave making plates 23. The limiting guide plate 24 is fixedly installed on the rotating drum 22. A rotating toggle body 25 is slidably installed in the limiting guide plate 24. The rotating toggle body 25 is fixedly connected to one end of the rotating shaft 26, and the other end of the rotating shaft 26 is installed and connected to the pre-degreasing container box 1. The wave maker 2 is used to disturb the pre-degreasing liquid to make periodic undulating motions, thereby causing the pre-degreasing liquid to generate waves.

[0023] Embodiment 1:

[0024] Specifically, the pre-degreasing container box 1 includes a degreasing box 11, a box cover 12, a placement shaft 13 and a driving motor 14. The box cover 12 is correspondingly rotatably installed on the degreasing box 11, and a plurality of the placement shafts 13 are rotatably installed inside the degreasing box 11. The output end of the driving motor 14 rotates through the degreasing box 11 and is fixedly connected to the other end of the rotating shaft 26. The number of driving motors 14 is the same as the number of wave makers 2. The degreasing box 11 is fixedly provided with a pipe mouth, which is used to discharge the degreasing liquid inside the degreasing box 11 out of the body. The box cover 12 is fixedly provided with a self-locking structure, and the box cover 12 can effectively and completely seal the degreasing box 11.

[0025] Specifically, there is a spacing between the placement axes 13 that does not allow steel pipes and joints to fall, and a wave maker 2 is provided below the placement axes 13. The spacing between the placement axes 13 can allow the insertion of vertical plates. The vertical plates can be inserted between the placement axes 13 to separate the placement areas of small steel pipes and special-shaped steel pipe joints, thereby limiting the range of movement of small steel pipes and special-shaped steel pipe joints.

[0026] Specifically, the two wave making plates 23 are arranged in an "eight" shape, and the limiting guide plate 24 arranged inside the wave making plate 23 is a "U" shaped structure. The wave making plate 23 can disturb the pre-degreasing liquid to make periodic undulating motion, thereby generating waves in the pre-degreasing liquid.

[0027] Specifically, the rotating toggle body 25 is an "L"-shaped structure as a whole. The rotating toggle body 25 is composed of a roller and an arc plate. The roller of the rotating toggle body 25 is slidably installed in the limiting guide plate 24, and the roller is fixedly installed at one end of the arc plate. The other end of the arc plate is fixedly connected to one end of the rotating shaft 26. The rotation of the rotating toggle body 25 can drive the limiting guide plate 24 to swing.

[0028] Embodiment 2:

[0029] The defects or problems raised in the above-mentioned background technology are mainly solved by the structure of the wave maker 2: when it is necessary to degrease the steel pipe, the steel pipe is directly placed on the several placement shafts 13 of the pre-degreasing container box 1; when it is necessary to degrease the small steel pipe and the special-shaped steel pipe joint, the rectangular vertical plate is inserted between the placement shafts 13, thereby dividing a part of the required placement area; after the steel pipe or the joint is placed, the box cover 12 of the pre-degreasing container box 1 is closed, the degreasing box 11 is sealed, and then the driving motor 14 is turned on, and the driving motor 14 drives the rotating shaft 26 of the wave maker 2, and the rotating shaft 26 drives the rotating toggle body 25 to rotate. The rotating toggle body 25 will drive the limit guide plate 24 to repeatedly swing left and right during the rotation process, and the limit guide plate 24 will drive the rotating drum 22. The rotating drum 22 disturbs the surrounding degreasing liquid through the wave-making plate 23. As the frequency of the disturbance gradually increases, the degreasing liquid will exhibit periodic ups and downs and gradually spread to the surroundings, thereby generating waves. In the process of propagation, the degreasing liquid in contact with the surface of the steel pipe will impact the surface of the steel pipe and drive the steel pipe to move in a small range, so that the steel pipes do not contact each other in a short period of time, so that the degreasing liquid can fully contact the surface of the steel pipe, and the degreasing efficiency and effect of the steel pipe are accelerated through the impact force of the degreasing liquid.

[0030] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
