Description

Technical Field

[0001] This utility model belongs to the field of steel pipe inner wall sandblasting technology, and in particular relates to a multi-station steel pipe inner wall sandblasting cleaning machine. Background Technology

[0002] Sandblasting of the inner wall of steel pipes is a surface treatment process that uses compressed air as power to propel abrasive particles of a certain size (such as steel grit, quartz sand, etc.) at high speed onto the inner wall surface of the steel pipe through sandblasting equipment. This process effectively removes impurities such as rust, scale, welding slag, and dirt from the inner wall of the steel pipe, while simultaneously creating a uniform roughness on the inner wall. This improves the cleanliness and roughness of the inner wall of the steel pipe, providing a good adhesion substrate for subsequent coating applications (such as anti-corrosion coatings, linings, etc.), enhancing the bonding force between the coating and the inner wall of the steel pipe, and extending the service life of the steel pipe. It is widely used in the pretreatment of the inner wall of steel pipes in industries such as petrochemicals, construction, and machinery manufacturing.

[0003] Chinese patent CN220994109U discloses a steel pipe inner wall sandblasting cleaning machine. The paper describes a machine that includes: a base plate, a sand storage box above the base plate, a high-pressure spray gun mounted on the bottom of the sand storage box, a feeding and circulation mechanism on the surface of the base plate for circulating sand particles ejected from the high-pressure spray gun, a filtering mechanism on the surface of the base plate below the sand storage box for filtering the sand particles ejected from the high-pressure spray gun, a protective mechanism on the bottom of the sand storage box for protecting sand particles splashed from the pipe opening of the steel pipe, and a fixing mechanism below the protective mechanism for fixing the steel pipe. The technical effects and advantages of this invention are: the feeding and circulation mechanism facilitates the collection and filtering of sand particles ejected from the high-pressure spray gun and their recycling into the sand storage box; the protective mechanism protects the pipe opening near the high-pressure spray gun, preventing some sand particles from splashing out.

[0004] However, the aforementioned method of using a conveyor belt to transport sand particles in the steel pipe inner wall sandblasting cleaning machine has significant drawbacks. Gaps exist between the conveyor belt and the feeding cylinder, causing sand particles to easily leak during transport. This not only wastes sand particles but also pollutes the surrounding environment and increases cleaning difficulty. Furthermore, the open design of the conveyor belt lacks sufficient sealing, making it susceptible to external interference, further exacerbating sand particle leakage and dust diffusion, affecting the cleanliness of the working environment. Therefore, designing a multi-station steel pipe inner wall sandblasting cleaning machine is essential. Utility Model Content

[0005] This utility model provides a multi-station steel pipe inner wall sandblasting cleaning machine, which aims to solve the problems of easy sand leakage, poor sealing, environmental pollution, and difficult cleaning of the conveyor belt gaps currently in use.

[0006] This utility model is implemented as follows: a multi-station steel pipe inner wall sandblasting cleaning machine includes: a steel pipe body; a sandblasting separation component assembled at one end of the steel pipe body, the sandblasting separation component being used to separate sand of different particle sizes; a sandblasting return component assembled at one end of the sandblasting separation component, the sandblasting return component being used to recycle the screened sand; a sandblasting grinding component assembled at one end of the sandblasting return component, the sandblasting grinding component being used to sandblast the inner wall of the steel pipe body; and a steel pipe clamping component assembled on the steel pipe body, the steel pipe clamping component being used to clamp the steel pipe body and reduce vibration.

[0007] Preferably, the sandblasting separation assembly includes: a sandblasting separation box connected to one end of the steel pipe body, a blower fixedly installed on the right side of the sandblasting separation box, a filter plate fixedly installed inside the sandblasting separation box, a guide plate fixedly installed inside the sandblasting separation box, and an exhaust fan fixedly installed on the top of the sandblasting separation box.

[0008] Preferably, the sandblasting recirculation assembly includes: a connecting pipe 1 fixedly installed at one end of the sandblasting separation box, a sand pump fixedly installed on the connecting pipe 1, a connecting pipe 2 fixedly installed at the other end of the connecting pipe 1, and a high-speed fan 1 fixedly installed on one side of the connecting pipe 2.

[0009] Preferably, the sandblasting recirculation assembly further includes: a connecting pipe three fixedly installed at one end of the connecting pipe two, and a high-speed fan two fixedly installed on one side of the connecting pipe three.

[0010] Preferably, the sandblasting and polishing assembly includes: a sandblasting box fixedly installed at one end of the connecting pipe, a vibration motor fixedly installed at one end of the sandblasting box, a protective shell fixedly installed at the bottom of the sandblasting box, and a sandblaster fixedly installed at the bottom of the sandblasting box.

[0011] Preferably, the steel pipe clamping assembly includes: an installation frame disposed at the bottom of the steel pipe body, a hydraulic telescopic rod fixedly installed inside the installation frame, a movable plate fixedly installed at one end of the hydraulic telescopic rod, and an arc-shaped plate fixedly installed at one end of the movable plate.

[0012] Preferably, the steel pipe clamping assembly further includes: a spring fixedly installed on the inner side of the arc-shaped plate, and a pipe clamp is fixedly installed on the inner side of the spring.

[0013] Preferably, there are two sets of hydraulic telescopic rods, movable plates, arc plates, and pipe clamps, which are symmetrically arranged on the mounting frame. There are multiple sets of springs, which are equidistantly arranged between the arc plates and the pipe clamps.

[0014] Compared with related technologies, the multi-station steel pipe inner wall sandblasting cleaning machine provided by this utility model has the following beneficial effects: When using a multi-station steel pipe internal wall sandblasting cleaning machine, the steel pipe body is first placed on the steel pipe clamping assembly. The moving plate and arc plate are pushed by a hydraulic telescopic rod, allowing the pipe clamp to tightly hold the steel pipe with the assistance of springs. This ensures the steel pipe is stable and vibration-damped during sandblasting, preventing sand leakage or pipe displacement due to vibration. Subsequently, the sandblasting and grinding assembly is activated. The vibrating motor drives the sand and gravel in the sandblasting box to be sprayed at high speed onto the inner wall of the steel pipe through the sandblaster for grinding. The sand and gravel mixture after sandblasting is sucked into the sandblasting separation box by the exhaust fan. Under the action of the blower, the dust is separated and discharged through the filter plate, while larger sand and gravel particles slide down the guide plate to the sandblasting return assembly. In the sandblasting return assembly, the sand pump sends the sand and gravel to the connecting pipe 2 through connecting pipe 1. High-speed fans 1 and 2 then take turns sending the sand and gravel to the connecting pipe 3, finally returning it to the sandblasting box for recycling. The entire process effectively solves the problems of sand leakage, poor sealing, environmental pollution, and difficult cleaning caused by traditional conveyor belts through sealed pipe and box design, while improving the recycling rate of sand and gravel and the overall operating efficiency of the equipment.
