[0002] Chemical equipment is a part of chemical machinery. Chemical machinery includes two parts: one is chemical machinery, which mainly refers to equipment such as fans, compressors, and various pumps for fluid transportation. Its main components are moving machines, and it is generally called chemical machinery. The other is chemical equipment, which mainly refers to machines with stationary components, such as separation equipment like towers, containers, and reactors. Sometimes it is also called non-standard equipment. The distinction between chemical machinery and other machinery is not very strict. For example, some pumps used in chemical processes are also general-purpose equipment used in other industrial sectors. During the production of these chemical equipment, sandblasting is generally required before the surface of the parts needs to be treated. Compressed air is used to propel abrasive materials, such as garnet sand, copper ore sand, and quartz sand, at high speed onto the equipment surface. Through impact and cutting action, surface contaminants are removed and the roughness is changed. During sandblasting, the operator wears protective gloves and picks up the ceramic sandblasting head connected to the pipeline, aiming it at the parts that need to be sandblasted. However, since the sandblasting head is made of ceramic, the operator needs to hold the sandblasting head for a long time, which leads to a high workload for the operator. Utility Model Content

[0018] The technical solution of this utility model will be clearly and thoroughly described below with reference to specific embodiments: See Figure 1 - Figure 5 As shown, the surface sandblasting device for chemical equipment in this embodiment includes a sandblasting machine 1 and a central control shell 5 fixedly installed on the upper end of the sandblasting machine 1. The sandblasting machine 1 is provided with a glove window 2 and an observation window 3. The glove window 2 is used to install operating gloves and is mainly used to isolate the operator's hands from the inside of the sandblasting machine 1 to prevent accidental injury to the operator when the sandblasting machine 1 is working. The observation window 3 is mainly used to observe the inside of the sandblasting machine 1. The glove window 2 and the observation window 3 are both existing technologies and will not be described in detail here. The central control shell 5 is fixedly installed on the upper end of the sandblasting machine 1. A conveying pipe 6 is movably installed inside the central control shell 5. A sandblasting head 4 is suspended inside the sandblasting machine 1. The end of the conveying pipe 6 is fixedly connected to the sandblasting head 4.

[0019] The operator places the chemical equipment to be sandblasted inside the sandblasting machine 1, then turns on the sandblasting machine 1 and related components, puts on operating gloves, observes the operation through the observation window 3, and aims the sandblasting head 4 at the area of ​​the chemical equipment that needs to be sandblasted. Through the setting of the delivery pipe 6, the sandblasting head 4 is suspended. When the operator is sandblasting, the way the sandblasting head 4 is held is changed, so that the sandblasting head 4, which originally required hand support, is self-supported and fixed by the delivery pipe 6, which can effectively reduce the workload of the operator.

[0020] A fixing plate 7 is fixedly installed inside the central control shell 5. Two guide side plates 10 are fixedly installed inside the central control shell 5. The fixing plate 7 is located between the two guide side plates 10. A movable plate 8 is movably installed between the two guide side plates 10. The movable plate 8 is fixedly connected to the conveying pipe 6. A circular hole for the conveying pipe 6 to pass through is opened through one side of the fixing plate 7. A first spring 9 is fixedly installed on the corresponding side of the fixing plate 7 and the movable plate 8. The fixing plate 7 is mainly used to fix the first spring 9. When the operator needs to move the position of the sandblasting head 4, he only needs to pull the sandblasting head 4 to put the sandblasting head 4 in the best sandblasting position and ensure the sandblasting effect.

[0021] The movable plate 8 has rectangular slots 12 on both sides. A locking block 13 is movably installed inside the rectangular slot 12. A second spring 14 is fixed to one end of the locking block 13. The end of the second spring 14 is fixedly connected to the inner wall of the rectangular slot 12. The guide side plate 10 has an inner groove 11 on one side corresponding to the fixed plate 7. Multiple locking slots 20 are equidistantly opened on the inner wall of the inner groove 11. The locking block 13 is engaged with the inner side of the corresponding locking slot 20. The cross-sections of the locking slot 20 and the locking block 13 are both set in right-angled triangles.

[0022] By adjusting the shapes of the slots 20 and the blocks 13, when the operator pulls down the blasting head 4, the blasting head 4 moves the conveying pipe 6, which in turn moves the moving plate 8. The moving plate 8 then moves the blocks 13 within the rectangular slot 12. Through its own structure, the blocks 13 automatically enter the next slot 20 as they move, facilitating the downward movement of the blasting head 4. However, when the blocks 13 are inside the slot 20, they cannot return to their initial position, ensuring that the blasting head 4 remains stationary during blasting. This allows the operator to hold the blasting head and blast according to the shape of the chemical equipment, blasting from a high position to a low position.

[0023] By using the locking block 13 and the locking slot 20 to cooperate, the sandblasting head 4 can be locked at any time when it gradually moves downwards. Therefore, it can be very suitable for sandblasting operations from high to low, which is practical and convenient for operators to carry out sandblasting operations.

[0024] Unlocking plates 17 are fixedly provided on the corresponding side of the two guide side plates 10. Multiple unlocking strips 19 are fixedly provided on the side of the unlocking plate 17 corresponding to the moving plate 8. Multiple through holes 18 are opened at one end of the moving plate 8 corresponding to the unlocking plate 17. The through holes 18 connect to the rectangular groove 12. An elastic strip 15 for engaging the locking block 13 is fixedly provided on the inner side of the rectangular groove 12. The elastic strip 15 is a deformable elastic element and is made of rubber elastic plate. Both the unlocking strip 19 and the elastic strip 15 are provided with inclined surfaces. The inner groove 11 is provided with a locking inclined surface 16 corresponding to the inner wall of the fixed plate 7.

[0025] After the operator finishes sandblasting, or when the height of the sandblasting head 4 needs to be adjusted upwards, the operator only needs to pull the sandblasting head 4 to the bottom, so that the locking block 13 contacts the locking slope 16 and the unlocking strip 19. Due to the characteristics of the unlocking strip 19, the locking block 13 is briefly held inside the rectangular groove 12. The first spring 9 drives the moving plate 8 to reset, and the moving plate 8 drives the conveying pipe 6 and the sandblasting head 4 to reset, until the moving plate 8 contacts the unlocking plate 17, and the unlocking plate 17 contacts the locking block 13, squeezing the locking block 13 out of the rectangular groove 12. The second spring 14 then allows the locking block 13 to extend again for the next use.

[0026] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
