Description

Technical Field

[0001] This utility model relates to the field of equipment related to anti-corrosion engineering, and more specifically, it relates to an automatic recovery sandblasting device for anti-corrosion engineering construction. Background Technology

[0002] During anti-corrosion construction, rust on the surface of metal parts must be removed before other anti-corrosion coatings can be sprayed onto them. Therefore, sandblasting equipment is used to spray abrasive particles onto the surface of the metal parts to remove rust. Existing automatic recovery sandblasting equipment typically uses a nozzle to blast the sand and a suction head to collect the abrasive particles. However, due to the lack of a closed space between the nozzle and suction head, the sprayed abrasive particles are scattered by the airflow, making collection difficult using only the suction head. This results in insufficient recovery of a large amount of abrasive particles, leading to significant waste. Furthermore, after recovering the abrasive particles, the suction head may absorb other substances from the construction environment, mixing them with the abrasive particles. Existing sandblasting equipment lacks a filtration structure, making it difficult to separate larger substances from the abrasive particles, thus affecting the normal operation of the sandblasting equipment.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an automatic recovery sandblasting device for anti-corrosion engineering construction, which has the following beneficial effects:

[0017] 1. This utility model, by setting a fixed cover, installs the suction head and sandblasting head through the fixed cover, and forms a closed space. When using the entire sandblasting device, the fixed cover is brought into contact with the surface of the metal part to be sandblasted. The sand and gravel in the storage tank are pumped into the sandblasting head through the first connecting pipe by the air pump and sprayed out from the sandblasting head. The rust is removed by the contact between the sand and gravel and the metal surface. At the same time as sandblasting, the sand and gravel and metal materials are pumped back into the storage tank through the second connecting pipe by the return pump, thereby completing the recovery of sand and gravel. This facilitates the reduction of sand loss during the sandblasting process and makes the entire sandblasting device easier to use.

[0018] 2. This utility model, by setting up a sandblasting structure, allows for the adjustment of the fixed cover's lateral orientation by an external motor mounted on the base plate when using the sandblasting head. An external motor on the rotating frame drives a threaded rod to rotate, which, through a threaded connection with a moving block, raises or lowers the moving block, thus changing the height of the fixed cover. An external motor on the connecting plate drives a second rotating column to rotate, changing the pitch angle of the fixed cover. The extension of a first electric push rod on the moving block brings the fixed cover into contact with the surface of the metal component at the sandblasting location. This facilitates adjustment of the fixed cover and sandblasting head's positions according to different construction environments, thereby improving the overall applicability of the device.

[0019] 3. This utility model, by setting a filter plate inside the storage tank, allows sand to return to the storage tank after sandblasting. The sand enters the storage tank through the discharge pipe and falls onto the filter plate. The sand passes through the storage tank to the bottom, while substances that cannot pass through the filter plate remain on it. To remove these substances, the second electric push rod extends, causing the top cover to rise and thus lifting the filter plate out of the storage tank. By removing the bolts from the connecting holes on the connecting column and collar, the filter plate can be disassembled, and the debris can be dumped. This facilitates the separation of larger debris from the sand, ensuring the long-term use of the entire sandblasting device. Attached Figure Description

The moving end of the first electric push rod 6 is fixedly provided with a connecting piece 17. The fixed cover 9 is fixedly provided with a connecting block 18. The connecting block 18 is fixedly provided with a second rotating column 19. The connecting piece 17 is provided with a second rotating hole 20.

The fixed cover 9 and the air pump 21 are provided with a first connecting pipe 24. The fixed cover 9 and the return pump 22 are provided with a second connecting pipe 25.

[0034] Specifically, when sandblasting and removing rust from the surface of metal parts, depending on the location of the metal surface to be sandblasted, the first rotating column 15 is rotated by an external motor on the base plate 1, changing the lateral orientation of the fixed cover 9. The threaded rod 13 is rotated by an external motor on the rotating frame 4, and the moving block 5 is raised or lowered by the threaded connection between the threaded rod 13 and the moving block 5, thereby changing the height of the fixed cover 9. The second rotating column 19 is rotated by an external motor on the connecting piece 17, thereby changing the pitch angle of the fixed cover 9. The extension of the first electric push rod 6 on the moving block 5 causes the fixed cover 9 to contact the surface of the metal part at the sandblasting location. The sand and gravel in the storage tank 3 are pumped into the sandblasting head 7 through the first connecting pipe 24 by the air pump 21 and sprayed out from the sandblasting head 7. The rust is removed by the contact between the sand and gravel and the metal surface. At the same time as sandblasting, the sand and gravel and metal materials are pumped back to the storage tank 3 through the second connecting pipe 25 by the return pump 22, completing the recovery of the sand and gravel and realizing the use of the entire sandblasting device.

[0035] Please refer to Figure 1-5 As one embodiment of sand filtration: extension plates 26 are fixedly provided on the side ends of storage tank 3 and top cover 10. Second electric push rods 27 are fixedly provided on the extension plates 26 at both ends of storage tank 3. The extension plates 26 at the side ends of top cover 10 are fixedly connected to the moving end of the second electric push rods 27. A collar 28 is fixedly provided at the lower end of top cover 10. A connecting post 29 is fixedly provided at the upper end of filter plate 11. The connecting post 29 and the collar 28 cooperate with each other. A connecting hole 30 is provided on both the connecting post 29 and the collar 28. A thread is provided in the connecting hole 30.

[0036] Specifically, when the sand returned to the storage tank 3 after sandblasting, it entered the storage tank 3 through the discharge pipe 23 and fell onto the filter plate 11. The sand passed through the storage tank 3 and reached the lower end of the storage tank 3. The material that could not pass through the filter plate 11 remained on the filter plate 11. When removing such material, the second electric push rod 27 extended to drive the upper cover 10 to rise, thereby lifting the filter plate 11 out of the storage tank 3. By removing the bolts in the connecting holes 30 provided on the connecting column 29 and the collar 28, the filter plate 11 was disassembled, and the debris was dumped, thereby separating the larger debris from the sand.

[0037] In summary, when using it as a whole:

[0038] When sandblasting to remove rust from the surface of metal parts, depending on the location of the metal surface to be sandblasted, the first rotating column 15 is rotated by an external motor on the base plate 1, changing the lateral orientation of the fixed cover 9. The threaded rod 13 is rotated by an external motor on the rotating frame 4, and the moving block 5 is raised or lowered by the threaded connection between the threaded rod 13 and the moving block 5, thereby changing the height of the fixed cover 9. The second rotating column 19 is rotated by an external motor on the connecting piece 17, thereby changing the pitch angle of the fixed cover 9. The extension of the first electric push rod 6 on the moving block 5 causes the fixed cover 9 to contact the surface of the metal part at the sandblasting location. The sand and gravel in the storage tank 3 are pumped into the sandblasting head 7 through the first connecting pipe 24 by the air pump 21 and sprayed out from the sandblasting head 7. The rust is removed by the contact between the sand and gravel and the metal surface. At the same time as sandblasting, the sand and gravel and metal materials are pumped back to the storage tank 3 through the second connecting pipe 25 by the return pump 22, completing the recovery of the sand and gravel and realizing the use of the entire sandblasting device.

[0039] When the sand returned to the storage tank 3 after sandblasting, it entered the storage tank 3 through the discharge pipe 23 and fell onto the filter plate 11. The sand passed through the storage tank 3 and reached the lower end of the storage tank 3. The material that could not pass through the filter plate 11 remained on the filter plate 11. When removing such material, the second electric push rod 27 extended to drive the upper cover 10 to rise, thereby lifting the filter plate 11 out of the storage tank 3. By removing the bolts in the connecting holes 30 provided on the connecting column 29 and the collar 28, the filter plate 11 was disassembled and the debris was dumped, thereby separating the larger debris from the sand.
