[0002] The pneumatic shot supply valve of a shot blasting machine is a key component that controls the quantitative supply of abrasive by using compressed air to drive the valve core. It is used in metal surface treatment and other scenarios, and has advantages such as precise flow control, wear resistance and durability, automatic adaptation, convenient maintenance and energy saving and safety, which significantly improves the efficiency and reliability of shot blasting process.

[0003] A pneumatic shot supply valve for a shot blasting machine generally consists of a valve body, a valve core, and sealing components. The pneumatic shot supply valve uses compressed air to drive the valve core. Through the processes of opening, flow regulation, and closing, combined with the control logic of linkage and safety interlock with the shot blaster, the valve achieves precise, efficient, and reliable control of abrasive supply in the shot blasting process with technical features such as non-contact sealing and impact-resistant structure.

[0004] The existing pneumatic shot supply valves for shot blasting machines cannot connect pipelines without tools, resulting in installation and maintenance relying on specialized tools, being time-consuming and labor-intensive, having a high operational threshold, and being prone to sealing leaks due to human error. This makes it difficult to meet the needs of emergency repairs and flexible production. Long-term use will also aggravate component wear, increase maintenance costs and abrasive consumption. It has significant shortcomings in terms of efficiency, cost, safety and flexibility. Therefore, a new pneumatic shot supply valve for shot blasting machines is proposed to solve the above problems.

Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Please refer to Figures 1 to 3 This utility model provides an embodiment of a pneumatic shot supply valve for a shot blasting machine, comprising a pneumatic shot supply valve 1, a transmission mechanism 2 fixedly connected to the bottom of the pneumatic shot supply valve 1, a sealing docking mechanism 3 fixedly connected inside the transmission mechanism 2, and a filtering mechanism 4 fixedly connected inside the transmission mechanism 2. The sealing docking mechanism 3 includes a fixed shell 31, the outer side of which is fixedly connected to the inside of the transmission mechanism 2, providing stable installation support and withstanding the mechanical force during pipe docking. One end of the fixed shell 31 is slidably connected to a compression ring 33, which can slide axially within the fixed shell 31, and is displaced by... The sealing assembly is used to achieve pipe sealing. A sliding ring 32 is fixedly connected to the side of the compression ring 33 away from the fixed shell 31. The sliding ring 32 moves synchronously with the compression ring 33. Its outer structure is used to cooperate with the inner wall of the pipe to achieve docking and positioning. Multiple limiting blocks 34 are fixedly connected to the outer side of the sliding ring 32. The limiting blocks 34 can be embedded in the limiting groove of the transmission pipe 22. The mechanical locking of the pipe connection is achieved through sliding and rotational actions to prevent axial dislodgement. A spring-loaded assembly 35 is fixedly connected inside the fixed shell 31. The spring-loaded assembly 35 can provide elastic recovery force after the pipe is docked, enhancing the stability of the sealing structure.

[0025] The rebound assembly 35 includes multiple springs 351. One end of each spring 351 is fixedly connected to the inside of the fixed housing 31, while the other end can store elastic potential energy after being compressed, providing a continuous rebound force for the sealing gasket 352. The other end of each spring 351 is fixedly connected to the sealing gasket 352. Under the action of the springs 351, the sealing gasket 352 is tightly attached to the compression ring 33 and the inner wall of the pipe, forming a dynamic sealing surface that effectively prevents media leakage. The outer side of the compression ring 33 is slidably connected to the outer side of the sealing gasket 352. The movement of the compression ring 33 can compress the sealing gasket 352, causing it to deform and conform to the inner wall of the pipe, thus improving the sealing effect. The outer side of the sealing gasket 352 is slidably connected to the inside of the fixed housing 31, maintaining a stable sealing trajectory under the limiting action of the fixed housing 31, ensuring the reliability of the sealing action.

[0026] The transmission mechanism 2 includes a fixed pipe 21, the top of which is fixedly connected to the bottom of the pneumatic shot supply valve 1, serving as the main channel for abrasive transmission. It connects the pneumatic shot supply valve 1 to the transmission pipes 22 on both sides. Both sides of the fixed pipe 21 are fixedly connected to transmission pipes 22. The transmission pipes 22 are used to realize pipe docking and media transmission. Their internal structure cooperates with the sealing docking mechanism 3 to complete the connection action. Multiple limiting grooves are opened inside the transmission pipe 22. The limiting grooves cooperate with the limiting blocks 34 to provide guidance and positioning trajectory for the movement and locking of the sliding ring 32. The outer side of the limiting block 34 is slidably connected to the inside of the limiting groove. By sliding and rotating along the limiting groove, the sliding ring 32 is converted from the initial position to the locked position, completing the pipe connection. The outer side of the sliding ring 32 is slidably connected to the inside of the transmission pipe 22, and can move axially and rotate circumferentially within the transmission pipe 22. Its outer wall fits against the inner wall of the transmission pipe 22 to ensure the stability of the docking process.

[0027] Reference Figure 1 , Figure 2 and Figure 4The filtration mechanism 4 includes a frame 41, the outer side of which is fixedly connected to the inside of the transmission pipe 22, providing a mounting carrier for the filter plate 42, allowing it to be stably positioned within the transmission pipe 22 to filter the medium. The filter plate 42 is slidably connected inside the frame 41, intercepting impurities in the medium. Its sliding design facilitates disassembly and replacement during maintenance. The outer side of the filter plate 42 is slidably connected to the inside of the transmission pipe 22, forming a flow channel with the inner wall of the transmission pipe 22. Impurities are blocked on one side by the filter plate 42, while the clean medium continues to be transmitted through the other side. A connecting plate 43 is fixedly connected to the outer side of the filter plate 42, used to connect the filter... The filter plate 42 and the limiting rod 44 move to allow for the installation or removal of the filter plate 42. The connecting plate 43 has two slots 46 inside, which cooperate with the anti-slip rings 45 to form a locking structure to prevent the filter plate 42 from shifting when the medium flows. The limiting rod 44 is slidably connected inside the connecting plate 43 and can move axially along the connecting plate 43. The changing position of the limiting rod allows for locking or releasing the filter plate 42. Two anti-slip rings 45 are fixedly connected to the outside of the limiting rod 44. The anti-slip rings 45 can be inserted into or released from the slots 46 under the action of the limiting rod 44. The stable installation of the filter plate 42 is ensured by friction and mechanical limiting.

[0028] Working principle: When the operator needs to connect the transmission pipe 22, the sliding ring 32 can be fixed on the outside of the pipe. Then, the sliding ring 32 is slid into the inside of the transmission pipe 22. The inside of the transmission pipe 22 has a limiting groove. The limiting block 34 can be aligned with the inside of the limiting groove and slid into the limiting groove. When it has slid all the way down, the sliding ring 32 can be rotated, causing the limiting block 34 to rotate inside the limiting groove. When the sliding ring 32 slides into the inside of the fixed shell 31, it will squeeze the sealing gasket 352 inward through the compression ring 33. After the pipe is installed, the pipe can be released. At this time, the multiple springs 351 inside the sealing gasket 352 will provide a rebound force, pushing the sealing gasket 352 outward, so that the sealing gasket 352 pushes the compression ring 33, thus restricting the limiting block 34 inside the limiting groove, thereby strengthening the connection of the pipe.

[0029] When the pipeline is put into operation, the frame 41 can filter out impurities in the water. When the frame 41 needs to be replaced, the limiting rod 44 can be pulled outward to make the anti-slip ring 45 disengage from the inside of the slot 46. At this time, the connecting plate 43 is no longer restricted by the limiting rod 44, so the connecting plate 43 can be pulled outward to move the frame 41 together, thereby removing the frame 41 from the inside of the transmission pipeline 22.

[0030] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
