Description

Technical Field

[0001] This utility model relates to the field of manufacturing steel pipe inner wall sandblasting system, specifically to a steel pipe inner wall sandblasting system. Background Technology

[0002] Currently, common steel pipe internal wall sandblasting systems on the market can only treat the inner wall of the steel pipe and cannot handle the chamfering at both ends. After cleaning the inner wall of the workpiece, customers still need to use specialized sandblasting equipment to treat the chamfers at both ends, which not only reduces production efficiency and increases the customer's equipment investment costs, but also increases energy consumption. For example, ordinary sandblasting machines cannot accurately and evenly sandblast the chamfered areas at both ends, which can easily lead to poor sandblasting results at the chamfers, affecting the overall sandblasting quality of the workpiece, making the sandblasting operation inefficient and difficult to guarantee quality. Therefore, there is an urgent need to develop a device specifically designed for efficient and precise sandblasting of workpieces with chamfered ends and their inner walls. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide a steel pipe inner wall sandblasting system.

[0004] To achieve the purpose of this utility model, the technical solution adopted is as follows:

[0005] A steel pipe inner wall sandblasting system, comprising:

[0006] A sandblasting chamber for processing steel pipes, wherein at least one steel pipe to be processed is provided in the sandblasting chamber, and workpiece roller rotating mechanisms are provided on both sides of the steel pipe to be processed, and the workpiece roller rotating mechanisms drive the steel pipe to be processed to rotate.

[0007] An electric door is provided on one side of the sandblasting chamber.

[0008] The spray gun is raised and lowered by an automatic lifting mechanism to help the nozzle of the spray gun perform sandblasting operations on specific areas of the steel pipe;

[0009] The automatic lifting mechanism is a lifting unit equipped with a spray gun fixing device, which mounts the spray gun on the spray gun fixing device.

[0010] The spray gun is connected to an electrically controlled sandblasting machine located outside the sandblasting chamber via a spray pipe. The electrically controlled sandblasting machine includes an electrically controlled sand valve and a sand chamber. The shot and compressed air in the sand chamber are mixed into a mixture with a certain density and speed through the electrically controlled sand valve and then sprayed out through the spray gun connected to the spray pipe.

[0011] The sandblasting chamber is connected to a dust removal system via a dust removal pipe at its top.

[0012] The bottom spiral recovery rod of the abrasive recovery system is installed below the sandblasting chamber to recover the mixture of sandblasting shot and sand dust.

[0013] The workpiece roller rotation mechanism includes a rubber-coated roller, which is connected to a geared drive motor via a coupling.

[0014] The dust removal system is a dust removal system equipped with a fan and a dust collector. The dust removal system treats the dust-laden gas inside the sandblasting chamber before discharging it.

[0015] The bottom spiral recovery rod of the abrasive recovery system recovers the blasting shot and sand dust mixture, which is then lifted to the top by an elevator and driven by the top spiral to the shot dust separator for separation. The separated blasting shot enters the shot storage box.

[0016] The electrically controlled sandblasting machine is fixed on a mobile trolley, which drives the electrically controlled sandblasting machine to move as needed.

[0017] A steel pipe inner wall sandblasting system also includes an electrical control system, which controls and coordinates the operation of the entire equipment to achieve the design objectives.

[0018] The beneficial effects of this utility model are as follows:

[0019] This system not only effectively solves the problem of sandblasting quality on the inner wall of the workpiece, but also further solves the problem of sandblasting quality on several chamfers at both ends. It combines the sandblasting processes of the inner wall and the chamfers into one, resulting in better processing quality and greatly improved sandblasting efficiency, thus meeting the customer's process requirements.

[0023] like Figure 1 The steel pipe inner wall sandblasting system shown includes a sandblasting chamber 1 for processing the steel pipe, a steel pipe 100 to be processed is arranged in the sandblasting chamber 1, and a workpiece roller rotating mechanism 2 is arranged on both sides of the steel pipe 100 to be processed, and the steel pipe 100 to be processed is rotated by the workpiece roller rotating mechanism 2.

[0024] The workpiece roller rotation mechanism 2 includes a rubber-coated roller 21, which is connected to a reduction drive motor 23 via a coupling 22. The rubber-coated roller 21 drives the steel pipe 100 to be processed to rotate.

[0025] An electric door 3 is provided on one side of the sandblasting chamber 1. The electric door 3 is an electric door with a pneumatic sealing strip 31 and an observation window 32.

[0026] The sandblasting chamber 1 is a large cavity that forms a closed cavity with the electric door 3 when processing workpieces, ensuring that dust cannot escape.

[0027] The spray gun 5 is raised and lowered by the automatic lifting mechanism 4 to help the nozzle of the spray gun 5 to perform sandblasting operation on a specific area of ​​the steel pipe 100.

[0028] The automatic lifting mechanism 4 is a lifting unit 42 equipped with a spray gun fixing device 41, which sets the spray gun 5 on the spray gun fixing device 41.

[0029] The spray gun 5 is connected to the electrically controlled sandblasting machine 7 located outside the sandblasting chamber 1 via the spray pipe 51. The electrically controlled sandblasting machine 7 includes an electrically controlled sand valve 71 and a sand chamber 72. The shot and compressed air in the sand chamber 72 are mixed into a mixture with a certain density and speed by the electrically controlled sand valve 71 and then sprayed out through the spray gun 5 connected to the spray pipe 51.

[0030] The dust removal system 10 is connected to the top of the sandblasting chamber 1 via a dust removal pipe 11.

[0031] The dust removal system 10 is a dust removal system 10 equipped with a fan and a dust collector (not shown in the figure). The dust removal system 10 treats the dust-laden gas in the sandblasting chamber 1 and then discharges it.

[0032] The bottom spiral recovery rod 61 of the abrasive recovery system 6 is installed below the sandblasting chamber 1 to recover the mixture of sandblasting shot and sand dust.

[0033] The mixture of blasting shot and sand dust collected by the bottom spiral recovery rod 61 of the abrasive recovery system 6 is lifted to the top by the elevator 62 and then driven to the shot dust separator 64 by the top spiral 63 for separation. The separated blasting shot enters the shot storage box 65 and is then periodically transported to the electrically controlled sandblasting machine 7.

[0034] The electrically controlled sandblasting machine 7 is fixed on the mobile trolley 8, and the mobile trolley 8 drives the electrically controlled sandblasting machine 7 to move as needed.

[0035] The electrical control system 9 controls and coordinates the operation of the entire equipment to achieve the design goals.

[0036] Because of the above structure, the working principle of this utility model is as follows:

[0037] Before the workpiece is placed into the workpiece roller rotation mechanism 2 inside the sandblasting chamber 1, the abrasive recovery system 6 and the dust removal system 10 should be turned on. After the workpiece (steel pipe 100 to be treated) is placed on the workpiece roller rotation mechanism 2 in the sandblasting chamber 1, the electric door 3 closes automatically, the automatic lifting mechanism 4 of the spray gun drives the spray gun 5 to a suitable position, the moving trolley 8 starts working, and drives the opened electric control sandblasting machine 7 and the spray gun 5 to move, so as to complete the treatment of the inner surface and the chamfer at both ends of the workpiece (steel pipe 100 to be treated).

[0038] The workpiece roller rotation mechanism 2 provides a self-rotation function during workpiece sandblasting to ensure that the workpiece is sandblasted evenly.

[0039] When the electric door 3 closes, the pneumatic sealing strip inflates and tightens to ensure complete sealing with the sandblasting chamber 1, preventing the escape of shot and dust. In addition, the electric door 3 is equipped with an observation window to facilitate observation of the workpiece's sandblasting process. The observation window can be equipped with a light source.

[0040] The abrasive recovery system 6 starts working when the sandblasting function is activated. The mixture of shot and dust falls into the bottom spiral. The sandblasting shot and dust mixture recovered by the bottom spiral recovery rod 61 of the abrasive recovery system 6 is lifted to the top by the elevator 62 and then driven to the shot and dust separator 64 by the top spiral 63 for separation. The separated sandblasting shot enters the shot storage box 65 and is then periodically transported to the electrically controlled sandblasting machine 7.

[0041] The electrically controlled sand valve 71 of the electrically controlled sandblasting machine 7 mixes compressed air and shot in a certain ratio, accelerates the shot to a suitable value, and sprays it into the interior of the workpiece.

[0042] The electrical control system 9 is the control unit of this equipment. It controls the movements of each moving part of the equipment and coordinates the overall operation to achieve the functions designed in the equipment. Different menus are customized for different workpieces, allowing users to select the appropriate menu based on the specific workpiece during operation.
