[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0029] It should also be noted that, for ease of description, the accompanying drawings show only the parts relevant to this application, not the entire structure. Throughout this specification, the same or similar reference numerals represent the same or similar structures, elements, or processes. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0030] like Figure 1 As shown, Figure 1The diagram shown is a schematic representation of the main structure of a shot blasting device according to an embodiment of this application. This application provides a shot blasting device, including: a shot blasting chamber 1, which includes a main body 1-1 and a chamber door 1-2, connected, for example, by a hinged connection. A track 2 is installed above the shot blasting chamber for a hook system 3 to move. The hook system 3 includes a hook 3-1, a gear 3-2, and an electric hoist 3-3, used to transport workpieces before and after shot blasting. A shot blasting chamber 1 is fixedly connected to one side of an elevator 5. A screw conveyor 4 is installed at the bottom of the chamber, transporting the steel shot collected from the hopper to the bottom of the elevator 5. The screw conveyor 4 includes a screw shaft, blades, and a shaft head, with the blades welded to the screw shaft. The lower roller of the elevator 5 is mounted on the end of the screw shaft of the screw conveyor 4 near the elevator 5. The screw conveyor 5 is driven by a cycloidal pinwheel reducer (equivalent to the power unit of the elevator 5) at the bottom of the elevator 5. The feed inlet of the elevator 5 is connected to the screw conveyor 4, and the discharge outlet is connected to a shot separator 6. During operation, the screw conveyor 4 transports the shot-sand mixture to the bottom of the elevator 5, where it is then lifted to the top and discharged into the shot separator 6 for shot-sand separation. The screw conveyor 4 and the elevator 5 together form a shot recovery system. The elevator 5 is also equipped with an inspection door, which facilitates the maintenance and installation of the hopper. It can also be used to maintain the lower transmission and promptly remove any blockages caused by the bottom shot.

[0031] In one embodiment, a liner is installed around the main body 1-1 of the shot blasting chamber. The purpose of this is to extend the service life of the shot blasting chamber as much as possible, while ensuring the safety of the operators.

[0032] In one embodiment, a collection port is provided at the lower part of the shot blasting chamber 1. The collection port can be funnel-shaped, so that the shot can flow effectively into the screw conveyor 4 at the bottom of the shot blasting chamber 1.

[0033] In one embodiment, the top of the shot blasting chamber 1 is provided with a two-layer sealing device. The first layer of sealing device includes a rubber curtain, and the second layer of sealing device can be made of a steel plate, such as a mechanical steel plate.

[0034] In one embodiment, a shot collection groove is provided below the shot blasting chamber door 1-2. The purpose of this groove is to collect the shot that falls when the door is opened, and to prevent the shot from falling to the ground and causing the operator to slip.

[0035] In one embodiment, the hook system 4 also includes a speed reduction device, which can slow down the rotation speed when the hook system drives the workpiece to be shot blasted to rotate, so that the workpiece to be cleaned (equivalent to the aforementioned shot blasting treatment) can be subjected to deep shot blasting in the shot blasting chamber 1.

[0036] The shot blasting equipment provided in this application embodiment also includes a primary shot blasting device 7, which is installed on the side wall of the shot blasting chamber 1. The shot separator 6 is fixedly connected to the primary shot blasting device 7 through a shot conveying pipe. Figure 2 The diagram shown is an enlarged structural schematic of a primary shot blasting device according to an embodiment of this application, including a shot blaster 7-1 and a shot blasting motor 7-2. The shot blaster 7-1 includes a feed pipe 7-11, a shot distribution wheel 7-12, blades 7-13, and a directional sleeve 7-14. This primary shot blasting device is responsible for the initial shot blasting of the workpiece to be shot blasted.

[0037] In one embodiment, the sidewall of the shot blasting chamber 1 on which the primary shot blasting device 7 is installed has a preset tilt angle. This design allows the shot propelled from the primary shot blasting device 7 to be more effectively projected onto the surface of the workpiece being cleaned.

[0038] The shot blasting equipment provided in this application embodiment also includes a depth shot blasting device 8, such as... Figure 3 As shown, a deep shot blasting device 8 of a shot blasting equipment according to an embodiment of this application is provided. The deep shot blasting device 8 can be located inside the shot blasting chamber 1 or outside the shot blasting chamber 1, placed side by side or in front of the primary shot blasting device 7. The deep shot blasting device includes a pressure tank 8-1 and a spray gun 8-2. One end of the pressure tank 8-1 is connected to the feed port 8-4 through a cone valve 8-3, and the other end is connected to the spray gun 8-2. A compressed air tank 8-5 is connected to the pressure tank 8-1 and the spray gun 8-2 through two air inlet pipes 8-6 respectively. In addition, the deep shot blasting device 8 is also provided with a sand adjusting valve 8-7 to adjust the sand output according to the actual operation needs.

[0039] The working principle of this deep shot blasting device is to use the mixture of compressed air and abrasive to expel abrasive from the spray gun, thereby performing shot blasting on the workpiece to be blasted. Because the spray gun is highly flexible, it can perform deep shot blasting on the remaining dead corners after the initial shot blasting.

[0040] like Figure 1 As shown, the shot blasting chamber door is equipped with a hole for inserting the shot blasting gun 8-2, a viewing window 10, and an explosion-proof light 11.

[0041] The shot blasting equipment provided in this application embodiment also includes a dust removal system 9, such as Figure 4 As shown, Figure 4 This diagram illustrates the connection between the shot blasting device and the dust removal system in a shot blasting equipment according to an embodiment of this application. One end of the elevator 5 is connected to the dust removal system 9 via a duct 10. The dust removal system 9 includes a dust removal fan 9-1 and a dust collector 9-2. This dust removal system primarily targets the oxide scale dust continuously generated during the shot blasting process, both to ensure the shot blasting effect on the workpiece and to prevent dust overflow and contamination of the workshop's working environment.

[0042] The shot blasting equipment provided in this application embodiment also includes an electrical control system, which is electrically connected to the primary shot blasting device, the deep shot blasting device, the screw conveyor, the elevator, the shot separator, and the dust removal system. The purpose is to allow for independent control of the operation of each of the aforementioned components.

[0043] In one embodiment, the electrical control system also includes an electrical interlock device, which ensures that the shot blaster can only operate after the hook rotates and the shot blasting chamber door is closed, thereby avoiding safety hazards caused by operator error.

[0044] The following is the operation procedure for this shot blasting equipment:

[0045] 1. Turn on the dust removal system 9, the elevator 5, the shot separator 6 and the screw conveyor 4 in sequence;

[0046] 2. Start the hook system 3. The hook 3 hangs the workpiece outside the shot blasting chamber. The hook system is used to transport the workpiece to be processed into the shot blasting chamber. Then the chamber door of the shot blasting chamber is closed. The hook starts to rotate. The rotation can be uniform. The speed is controlled by the electronic control system.

[0047] 3. Start the primary shot blasting device 7 to perform preliminary shot blasting on the workpiece to be processed;

[0048] 4. After the initial shot blasting operation is completed, start the deep shot blasting device 8, put the spray gun 8-2 into the hole of the shot blasting chamber door, and perform deep shot blasting on the workpiece through the viewing window;

[0049] 5. After the workpiece to be processed is completed, turn off the deep shot blasting device 8, stop the hook from rotating, open the shot blasting chamber door, and use the hook system to transport the processed workpiece to the outside of the shot blasting chamber door for unloading.

[0050] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
