Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting and rust removal, and more specifically to rust removal equipment for metal surface treatment. Background Art

[0002] In the metal processing and manufacturing industries, metal pipes are widely used in various fields, such as fluid pipelines and mechanical components, due to their excellent electrical and thermal conductivity and structural strength. However, during processing, storage, and use, metal pipes are prone to forming an oxide layer on their inner walls, commonly known as "rust." This not only affects the pipe's appearance but, more importantly, reduces its performance, such as corrosion resistance and fluid flow efficiency, and may even pose a safety hazard in certain critical applications.

[0003] Traditional methods for removing rust from the inner walls of metal pipes mainly include chemical cleaning and mechanical grinding. Although chemical cleaning can effectively remove oxides, the chemical reagents used may cause environmental pollution, and the cost of treating the waste liquid after treatment is high; mechanical grinding is inefficient, making it difficult to uniformly treat the inner wall of the pipe and easily damaging the surface of the pipe, affecting its service life.

[0004] In recent years, with the continuous improvement of industrial automation and environmental protection requirements, seeking an efficient and environmentally friendly rust removal technology for the inner wall of metal pipes has become an urgent need in the industry. Sandblasting technology, as a physical rust removal method, has attracted widespread attention because it can efficiently remove dirt and oxides on the metal surface without causing excessive damage to the substrate. However, when applying sandblasting technology to the inner wall treatment of metal pipes, it is necessary to ensure the precise positioning of the pipes. At the same time, the waste and dust generated during the sandblasting process need to be collected and processed to prevent the oxide particles in the waste and the heavy metals or other harmful substances contained in the abrasive from being directly discharged into the air from the other end of the pipe. These waste and dust can easily cause health problems such as skin inflammation and eye damage after contacting the workers' skin or entering the eyes. Utility Model Content

[0026] Example 1:

[0027] See also Figure 1-3A rust removal device for metal surface treatment includes a workbench 1 and a handheld sandblasting gun 10. The workbench 1 is provided with a clamping mechanism and a positioning dust removal mechanism.

[0028] The clamping mechanism includes a positioning frame 2 fixed to the upper end of the workbench 1, and a fixed splint 3 is fixedly connected to the workbench 1 and on the front and rear sides of the positioning frame 2. A pair of slide grooves 201 are provided on the positioning frame 2, and a movable splint 4 is slidably connected in the slide grooves 201. Ball grooves are provided at both ends of the movable splint 4, and balls 403 are installed in the spherical grooves. The balls 403 are slidably connected to the slide grooves 201 to reduce the friction force of the movable splint 4 when sliding in the slide grooves 201. An electric push rod 5 is installed on the upper end of the positioning frame 2, and the output end of the electric push rod 5 is fixedly connected to the drive shaft 6. The end of the drive shaft 6 away from the electric push rod 5 is fixedly connected to the movable splint 4. The fixed splint 3 and the movable splint 4 are close to each other. A positioning groove 1 301 and a positioning groove 2 401 are respectively provided at the ends, and a metal pipe is provided between the positioning groove 1 301 and the positioning groove 2 401. When the movable splint 4 slides to the lowermost side of the slide groove 201, the lengths of the two oblique sides on the "V"-shaped groove match the diameter of the metal pipe 7, and the metal pipe 7 can be clamped. A plurality of fastening protrusions 402 are fixedly connected to the side wall of the positioning groove 201, and the plurality of fastening protrusions 402 are evenly spaced on the "V"-shaped path on the positioning groove 201. The fastening protrusions 402 are rubber protrusions, and the rubber protrusions are semicircular. The fastening protrusions 402 are used to fill the possible gaps between the movable splint 4 and the metal pipe 7 and increase the friction between the two, thereby improving the clamping stability.

[0029] The positioning dust removal mechanism includes a connecting rod 8 fixed to the rear end of the movable splint 4, and the end of the connecting rod 8 away from the movable splint 4 is fixedly connected to the limit plate 9. Before the sandblasting and rust removal operation, when the metal pipe 7 is placed between the positioning groove 1 301 and the positioning groove 2 401, one end of the connecting rod 8 needs to be pushed to the side close to the limit plate 9 until the limit plate 9 is close to one end of the metal pipe 7 and fits with it. Then the electric push rod 5 is controlled to start and drive the movable splint 4 to slide downward, so that the metal pipe 7 can be clamped. A dust suction air outlet 901 is provided on the limit plate 9. When the metal pipe 7 is clamped between the positioning groove 1 301 and the positioning groove 2 401, that is, when the movable splint 4 slides to the lowermost side of the slide groove 201, the dust suction air outlet 901 Coaxial with the center of the metal pipe 7, the metal pipe 7 is blocked by a limit plate 9 to prevent the waste and dust generated during the sandblasting process from being directly discharged into the air from the other end of the metal pipe 7. A dust suction device is externally connected to the dust suction port 901, which is not shown in this figure. The dust suction device is started synchronously during the sandblasting process. Usually, the dust suction port is directly connected to the pipeline, which may have a certain impact on the sandblasting effect. Therefore, during use, the suction force of the dust suction device and the sand flow intensity sprayed by the sandblasting gun 10 will be adjusted to avoid interference with the sandblasting effect as much as possible while preventing waste and dust from flowing back due to the blocking of one end of the metal pipe 7, thereby reducing the possibility of airflow interference and waste escape.

[0030] When the metal pipe 7 is in the process of being sandblasted and rust-removed, the dust collecting device is started, and the waste material and dust generated after sandblasting and rust-removing on the inner wall of the metal pipe 7 are timely absorbed. Compared with the prior art, the present invention can realize the process of sandblasting and rust-removing on the metal pipe 7, preventing the waste material and dust from being randomly discharged from one end of the metal pipe 7 into the air and overflowing into the entire workshop from the end of the metal pipe 7, thereby optimizing the working environment of the workers and effectively preventing the occurrence of occupational diseases.

[0031] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
