Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, and more specifically, to a shot blasting device for valve processing. Background Technology

[0002] After prolonged use, valves develop rust, scale, and other coatings on their surfaces. Therefore, shot blasting is necessary to remove these coatings during valve maintenance and repair. The working principle of shot blasting is to use a shot blaster to propel shot at high speed, giving the shot kinetic energy. The high-speed, linearly moving shot directly impacts the valve surface, thereby removing the coating.

[0003] Announcement No. CN215036585U proposes a valve shot blasting device. This device solves the problem that existing shot blasting devices have fixed shot blaster positions and consistent shot angles, making it difficult to uniformly coat the valve surface and resulting in poor treatment effects. However, this device can only process one valve at a time, and the shot blasting efficiency needs to be improved. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a shot blasting device for valve processing.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A shot blasting device for valve processing includes a processing cylinder, a side-opening door rotatably connected to the front side of the processing cylinder, an electric push rod disposed on the rear side of the processing cylinder, a slide rail and a cylinder disposed inside the processing cylinder, a mounting plate connected to the electric push rod disposed on the slide rail, a rotating roller rotatably connected to the mounting plate and a drive assembly connected to the rotating roller fixedly disposed on the mounting plate, a number of sets of inclined upward insert rollers equidistantly arranged along the height direction and on the circumference, and a shot blaster slidably fitted on the inner wall of the processing cylinder, the shot blaster being connected to the cylinder.

[0007] This device can significantly increase the number of valves that can be shot blasted at one time. With adjacent valves placed at intervals, the shot blasting process for valves of different heights can be achieved through the vertical reciprocating lifting of the shot blaster and the uniform rotation of the rotating roller. The shot blasting effect is further improved and the results are excellent.

[0008] Furthermore, the drive assembly employs gear transmission.

[0009] Furthermore, a discharge port is provided at the bottom of the processing cylinder, and a collection box is placed below the discharge port.

[0010] In the above scheme, the shot and the covering layer after shot blasting can be recycled into the collection box through the discharge port.

[0011] Furthermore, a suction pump is installed on the processing cylinder, and a pipeline connected to the suction pump is installed inside the processing cylinder. Several atomizing nozzles are installed on the pipeline, and the atomizing nozzles are correspondingly arranged with several sets of insert rollers. The suction pump is connected to the anti-rust paint box.

[0012] Furthermore, the atomizing nozzle and the shot blaster are arranged in a front-to-back pattern.

[0013] After the shot blasting of the valve is completed, the electric push rod drives the rotating roller to move towards the side-opening door. When the rotating roller moves to the anti-rust painting area, it stops (the anti-rust painting area and the shot blasting area are distributed in front and behind each other and do not affect each other). At this time, the controller controls the suction pump to work so that the anti-rust paint can be atomized and sprayed onto the surface of the valve. At this time, the drive component operates so that the valve rotates at a constant speed with the rotating roller again. After the anti-rust painting treatment is completed, the side-opening door is finally opened to discharge the valve. This reduces the labor intensity of subsequent manual anti-rust painting.

[0014] Furthermore, a negative pressure fan is installed on the processing cylinder, and the negative pressure fan is connected to a spray chamber, which is equipped with spraying equipment.

[0015] The above solution allows the controller to operate the negative pressure fan after the anti-rust paint is applied, which can quickly draw the remaining atomized paint in the processing cylinder into the spray chamber and then use the spray equipment to settle it, thereby avoiding the problem of atomized paint spilling everywhere and polluting the surrounding environment when the side door is opened for unloading.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] Compared to existing technologies, this device can significantly increase the number of valves that can be shot blasted in one operation. Furthermore, adjacent valves are placed at intervals, and the shot blasting process for valves of different heights can be achieved through the vertical reciprocating lifting of the shot blaster and the uniform rotation of the rotating roller. This further improves the shot blasting effect and efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0025] like Figures 1 to 4 As shown, a shot blasting device for valve processing includes a processing cylinder 1. A side-opening door 12 is rotatably connected to the front side of the processing cylinder 1. An electric push rod 101 is provided on the rear side of the processing cylinder 1. A slide rail 13 and a cylinder 22 are provided inside the processing cylinder 1. A mounting plate 14 connected to the electric push rod 101 is provided on the slide rail 13. A rotating roller 15 is rotatably connected to the mounting plate 14 via a bearing, and a drive assembly 17 connected to the rotating roller 15 is fixedly provided. Specifically, the drive assembly 17 adopts gear transmission, which is a prior art principle and will not be described. Several sets of inclined upward insert rollers 16 are equidistantly arranged along the height direction and circumferentially spaced for batch interleaved placement of valves. In a more detailed design, each set of insert rollers 16 includes four.

[0026] A shot blaster 21 is slidably fitted on the inner wall of the processing cylinder 1. The shot blaster 21 is existing technology and will not be improved. It adopts the same shot blaster 21 in the valve shot blasting device proposed in announcement number CN215036585U and will not be improved. The shot blaster 21 is connected to a cylinder 22 (specifically, a track is set inside the processing cylinder 1, a slider is set on the track, and the shot blaster 21 is set on the slider. The track and the slider are shown in the figure but are not labeled).

[0027] Further refinements of the embodiments of this utility model, such as... Figures 1 to 4 As shown, a discharge port 11 is provided below the processing cylinder 1, and a collection box is placed below the discharge port 11. The collection box is not shown in the figure. The shot and the covering layer after shot blasting can be recycled into the collection box through the discharge port 11.

[0028] It should be noted that the electric push rod 101, drive assembly 17, cylinder 22 and shot blaster 21 are all electrically connected to the controller, which is not shown in the figure.

[0029] The working process of this utility model is as follows:

[0030] First, open the side door 12. Then, the controller controls the electric push rod 101 to work, which causes the rotating roller 15 to move outward to facilitate the placement of the valve onto the insertion roller 16. The valve is not shown in the figure. During installation, one of the holes on the valve is passed through the insertion roller 16 to achieve quick installation. Since one end of the insertion roller 16 is tilted upward, the valve is not easy to fall off during shot blasting. During the installation process, the controller can control the drive component 17 to work, which changes the position of the rotating roller 15 to facilitate the placement of the valve onto the insertion roller 16 in different positions. After all the insertion rollers 16 have placed the valve, there is a certain gap between the valves. Then, the controller controls the electric push rod 101 to work again, which causes the rotating roller 15 to move back to the initial position, that is, the rotating roller 15 is away from the side door 12 and is in the shot blasting area inside the processing cylinder 1. This area is directly opposite the shot blaster 21. Finally, close the side door 12.

[0031] The controller then controls the drive assembly 17 to work so that several valves rotate at a uniform speed along with the rotating roller 15. During the rotation, the controller then controls the shot blaster 21 to work, which can realize the shot blasting process of the valves. The shot blaster 21 can make vertical reciprocating lifting and lowering movements, which can effectively blast several groups of valves at different heights, thereby uniformly treating the coating layer on the valve surface and removing the coating layer. After the shot blasting is completed, the side door 12 is opened first, and then the rotating roller 15 moves outward again. After the movement is completed, the valves can be unloaded in sequence. After all the valves in this batch are unloaded, a new batch of valves is replaced and a new round of valve shot blasting process can be started.

[0032] Compared to existing technologies, this device can significantly increase the number of valves that can be shot blasted in one operation. Furthermore, adjacent valves are placed at intervals, and the shot blasting process for valves of different heights can be achieved through the vertical reciprocating lifting of the shot blaster and the uniform rotation of the rotating roller. This further improves the shot blasting effect and efficiency.

[0033] In other embodiments, such as Figure 3As shown, a suction pump 41 is installed on the processing cylinder 1, and a pipeline 42 connected to the suction pump 41 is installed inside the processing cylinder 1. Several atomizing nozzles 43 are installed on the pipeline 42, and the atomizing nozzles 43 are correspondingly arranged with several sets of rollers 16. The suction pump 41 is connected to the anti-rust paint box, which is not shown in the figure, and the atomizing nozzles 43 and the shot blaster 21 are distributed in a front-to-back manner. In this embodiment, after the shot blasting of the valve is completed, the electric push rod 101 drives the rotating roller 15 to move towards the side door 12. When the rotating roller 15 moves to the anti-rust paint spraying area, it stops (the front-to-back distribution of the anti-rust paint spraying area and the shot blasting area does not affect each other). At this time, the controller controls the suction pump 41 to work so that the anti-rust paint can be atomized and sprayed onto the surface of the valve. At this time, the drive component 17 operates so that the valve rotates at a uniform speed with the rotating roller 15 again. After the anti-rust paint spraying is completed, the side door 12 is finally opened to discharge the valve, thus reducing the labor intensity of subsequent manual anti-rust paint spraying.

[0034] A further optimization of the above embodiment is that a negative pressure fan is installed on the processing cylinder 1, and the negative pressure fan is connected to a spray chamber. A spraying device is installed in the spray chamber. This embodiment is not shown in the figure. The spraying device adopts existing technology without modification (specifically, it consists of a water pump and an atomizing nozzle). In this embodiment, after the anti-rust paint is sprayed, the controller controls the negative pressure fan to work, which can quickly draw the remaining atomized paint in the processing cylinder into the spray chamber and then use the spraying device to settle it, thereby avoiding the problem of atomized paint overflowing everywhere and polluting the surrounding environment when the side door is opened for unloading.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
