Description

Technical Field

[0001] This utility model belongs to the field of steel structure processing technology, and in particular relates to an integrated treatment device for sandblasting, rust removal and roughening of steel structures. Background Technology

[0002] Sandblasting removes rust by using compressed air to create a high-speed jet, which propels the abrasive material onto the workpiece surface. The impact and cutting action of the abrasive removes rust, oil, and other contaminants, resulting in a clean surface. Roughening, through specific processes (such as sandblasting and shot blasting), creates a certain degree of roughness on the workpiece surface to enhance the adhesion of subsequent coatings (such as paint and plating) to the workpiece surface.

[0003] In the processing and maintenance of steel structures, surface rust removal and roughening treatment, followed by the application of a protective coating, can improve their service life. However, the abrasives used in the rust removal and roughening processes differ in particle size and hardness, requiring the two processes to be carried out separately. This staged operation significantly increases the preparation steps and time before processing. Therefore, it is necessary to provide an integrated sandblasting rust removal and roughening treatment device for steel structures, which integrates rust removal and roughening functions, and is equipped with a switching structure to achieve seamless switching, reduce preparation steps, and shorten preparation time.

[0028] Figure 1-6 This invention illustrates an embodiment of an integrated sandblasting, rust removal, and roughening treatment device for steel structures, comprising a pressure tank 1; a partition 2 fixedly connected to the inner cavity of the pressure tank 1; a switching box 3 fixedly connected to the bottom of the pressure tank 1; an air inlet pipe 4 extending through the inner cavity of the pressure tank 1; an air inlet assembly 5 located at the top of the inner cavity of the pressure tank 1; and material discharge pipes 6 fixedly connected to both sides of the bottom of the pressure tank 1, communicating with the pressure tank 1. Material receiving pipes 7 fixedly connected to both sides of the top of the switching box 3, communicating with it. The top of 7 is connected to the bottom of the feed pipe 6. The bottom of the switching box 3 is fixedly connected to the feed pipe 8, which is connected to it. The right end of the feed pipe 8 is fixedly connected to the spray pipe 10, which is connected to it. The middle of the air inlet pipe 4 is provided with a first opening and closing valve. The left side of the surface of the feed pipe 8 is provided with a second opening and closing valve. The surface of the pressure tank 1 is fixedly connected with four ring-shaped support legs, and the bottom of the support legs is equipped with a self-locking wheel. The bottom end of the air inlet pipe 4 is connected to the feed pipe 8. The inner cavity of the switching box 3 is provided with a switching component 9.

[0029] By adopting the above solution: the present invention pressurizes the storage location and delivery pipeline of the spraying medium by using the air inlet pipe 4, the air inlet component 5 and the material delivery pipe 8 together, thereby increasing the spraying intensity. At the same time, with the cooperation of the partition plate 2, the switching box 3 and the switching component 9, the spraying medium can be selectively used, thereby realizing the integrated use of rust removal and roughening functions, eliminating the need to change the spraying medium, and shortening the processing preparation steps and time.

[0030] refer to Figure 1 and Figure 3 The air intake assembly 5 includes exhaust pipes 51 fixedly connected to both sides of the inner cavity of the pressure tank 1. The exhaust pipes 51 are connected to the air inlet pipe 4. Four annularly distributed exhaust holes 52 are opened on both sides of the surface of the exhaust pipes 51. A slidable sliding sleeve 53 is fitted on the top of the surface of the exhaust pipes 51. A rubber plug 54 is fixedly connected to the top of the sliding sleeve 53. A feeding bin 55 is fixedly connected to both sides of the top of the pressure tank 1.

[0031] The above solution is adopted: by setting the air intake component 5, the exhaust pipe 51 and the exhaust hole 52 are used together to allow compressed gas in the inner cavity of the air inlet pipe 4 to be introduced into the inner cavity of the pressure tank 1. At the same time, with the cooperation of the sliding sleeve 53 and the rubber plug 54, the gas can be lifted to block the feeding bin 55 when the pressure tank 1 is filled with gas, thereby forming a sealed environment in the inner cavity of the pressure tank 1, eliminating the need for manual sealing.

[0032] refer to Figure 2 , 4 5 and Figure 6 The switching assembly 9 includes a switching disk 91 rotatably connected to the inner cavity of the switching box 3. An upper flow channel 92 is provided on the top of the surface of the switching disk 91, and a lower flow channel 93 is provided on the bottom of the surface of the switching disk 91. A rotatable telescopic cylinder 94 is installed on the front side of the switching box 3. A rotating part 95 is fixedly connected to the front end of the switching disk 91, and the top end of the rotating part 95 is rotatably connected to the output end of the telescopic cylinder 94.

[0033] The above solution is adopted: by setting the switching component 9, in which the telescopic cylinder 94 and the rotating component 95 work together to drive the switching disk 91 to rotate, so that the switching disk 91 can drive the upper flow channel 92 or the lower flow channel 93 to the designated position, thereby selectively conveying rust removal sand and coarse sand, eliminating the need to change the spraying medium, and improving the convenience and functional integration in actual use.

[0034] Working Principle: In use, the user first pours rust-removing sand and coarse sand from the feeding bin 55 into the two sides of the inner cavity of the pressure tank 1. The partition 2 separates the rust-removing sand and coarse sand for storage. Then, the user connects the external compressed air pump to the conveying pipe 8, turns on the compressed air pump, and opens the first on / off valve, allowing compressed air to enter the inner cavity of the air inlet pipe 4. The compressed air then enters the inner cavity of the exhaust pipe 51 and exits through the exhaust port 52 at the top of the exhaust pipe 51. The gas exiting the exhaust pipe 51 lifts the sliding sleeve 53, causing the sliding sleeve 53 and the rubber plug 54 to rise and press against the inner wall of the feeding bin 55, sealing the feeding bin 55. Simultaneously, the gas enters the inner cavity of the pressure tank 1, compressing its inner cavity. The user then opens the second valve, controlling the telescopic cylinder 94 to open and push the rotating part 95. 5. During the rotation, the switching disc 91 rotates within the switching box 3. At this time, the receiving pipe 7 on the left is connected to the inner cavity of the conveying pipe 8 through the lower flow channel 93. Under the combined pressure of the pressure tank 1 from top to bottom and the conveying pipe 8 from left to right, the rust-removing sand enters the inner cavity of the spray pipe 10 and is sprayed onto the steel structure surface for rust removal. After the rust removal is completed, the telescopic cylinder 94 is restarted and drives the rotating part 95 to rotate, causing the rotating part 95 to drive the switching disc 91 to rotate in the opposite direction within the switching box 3. This connects the inner cavity of the upper flow channel 92 with the inner cavity of the receiving pipe 7 on the right, and its bottom is simultaneously connected to the inner cavity of the conveying pipe 8. At this time, the receiving pipe 7 on the left is blocked by the surface of the switching disc 91, and the rust-removing sand stops being conveyed. The coarse sand enters the inner cavity of the conveying pipe 8 from the inner cavity of the upper flow channel 92 and is sprayed out through the inner cavity of the spray pipe 10 to roughen the steel structure.

[0035] In summary, this integrated sandblasting and roughening treatment device for steel structures, through the coordinated use of air inlet pipe 4, air intake component 5, and material conveying pipe 8, pressurizes the storage location and conveying pipeline of the blasting medium, thereby increasing the blasting intensity. At the same time, with the coordinated use of partition plate 2, switching box 3, and switching component 9, the blasting medium can be selectively used, thus achieving integrated use of rust removal and roughening functions, eliminating the need to change the blasting medium, and shortening the processing preparation steps and time.

[0036] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
