Description

Technical Field

[0001] This utility model relates to the field of heat treatment sandblasting technology, and in particular to a vibrating screen for heat treatment sandblasting process. Background Technology

[0002] Sandblasting is an important method for cleaning oxide scale and residues from the surface of workpieces after heat treatment and increasing surface roughness. This process uses high-speed jets of abrasive to impact the workpiece surface. During repeated use, the abrasive breaks down and pulverizes due to the impact, while also mixing in impurities removed from the workpiece.

[0003] If these broken abrasive particles and impurities are not separated in time, it will lead to problems such as reduced sandblasting efficiency, deterioration of workpiece surface quality, accelerated equipment wear, and environmental pollution. At present, common vibrating screens have limited functions, are mostly single-layer structures, can only separate oversized impurities, cannot perform fine classification of abrasive particles, and the screens are prone to clogging, making cleaning and maintenance inconvenient and affecting continuous production efficiency. Utility Model Content

It can accurately classify the used abrasive into components of different particle sizes, which is convenient for classification and recycling, effectively improving the sandblasting quality and abrasive utilization rate. It can effectively remove particles that clog the screen holes, prevent screen blockage, ensure continuous and stable screening efficiency, reduce downtime for cleaning, and effectively solve the problems in the background technology.

[0005] To achieve the aforementioned objective, this utility model adopts the following technical solution: A vibrating screen for heat treatment sandblasting includes a frame.

Detailed Implementation

[0015] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0016] Please see Figure 1-4This embodiment provides a technical solution: a vibrating screen for heat treatment sandblasting process, including a frame 1, a vibration auxiliary unit 3 on the inner side of the frame 1, a mounting frame 2 fixed on the vibration auxiliary unit 3, a vibration motor 7 installed on the top of the mounting frame 2, three screen boxes 6 fixed on the inner side of the mounting frame 2, the three screen boxes 6 are arranged in a stepped manner, adjacent screen boxes 6 are connected by a conveying pipe 10, a screen mesh 9 is fixed inside the screen box 6, the aperture of the three screen meshes 9 decreases from high to low, the top of the screen box 6 at the high position is connected to and fixed with a feed pipe 5, the bottom of the screen box 6 at the low position is connected to and fixed with a discharge pipe 11, and a cleaning unit 4 is installed on the frame 1 corresponding to the position of the screen mesh 9.

[0017] It also includes a maintenance window 8, which is installed on the side of the screen box 6. The maintenance window 8 makes it easy for staff to observe the screening situation inside the screen box 6, replace the screen 9, or clean the inside, which greatly reduces the difficulty and time cost of equipment maintenance.

[0018] The vibration auxiliary unit 3 includes a guide rod 31 and a slider 33. The end of the guide rod 31 is fixedly connected to the frame 1, and the slider 33 is fixed to the side of the mounting frame 2. The slider 33 is slidably connected to the guide rod 31. The vibration auxiliary unit 3 also includes a spring 32, which is sleeved on the guide rod 31 and positioned between the slider 33 and the frame 1. When the vibration motor 7 starts, it drives the entire mounting frame 2 and its three screen boxes 6 to perform high-frequency directional vibration under the guidance and buffering of the vibration auxiliary unit 3. The mixed abrasive enters the uppermost screen box 6 from the feed pipe 5. Under the vibration screening of the large-aperture screen 9, the largest particles of material are intercepted, and the remaining material falls into the middle screen box 6 through the conveying pipe 10. This process is repeated, and the material is precisely graded according to particle size after three stages of screening. The qualified material from each stage of screening falls through the screen into the corresponding screen box 6. At the bottom, all the fine material that passes through the lowest screen 9 is discharged from the discharge pipe 11. During the vibration process, the mounting frame 2 drives the slider 33 to slide along the guide rod 31. The spring 32 undergoes elastic deformation, and the deformation force of the spring 32 reacts to the slider 33, so that the slider 33 can reciprocate along the guide rod 31, thereby allowing the screen box 6 to reciprocate back and forth. Through the three layers of screens 9 arranged in a stepped manner with progressively smaller apertures, the used abrasive can be accurately classified into components of different particle sizes, which is convenient for classification and recycling, effectively improving the sandblasting quality and abrasive utilization rate. The combination of "guide rod 31 + slider 33 + spring 32" provides precise guidance and effective elastic support for the mounting frame, so that the excitation force of the vibration motor 7 can be efficiently converted into the directional vibration of the screen box 6, and the operation is stable.

[0019] The cleaning unit 4 includes a connecting rod 41 and a cleaning brush 43. The connecting rod 41 is fixed to the side of the frame 1, and the cleaning brush 43 is fixed to the end of the connecting rod 41. The bristles of the cleaning brush 43 are in contact with the bottom of the screen 9. The screen box 6 is movably connected to the connecting rod 41. The cleaning unit 4 also includes a guide seat 42, which is fixed to the side of the screen box 6 and movably connected to the connecting rod 41. During the entire screening process, as the screen box 6 carries the screen 9 and moves back and forth relative to the fixed cleaning brush 43, the bristles continuously scrape the bottom of the screen 9, thereby effectively cleaning the particles blocked in the mesh, keeping the screen unobstructed, ensuring the continuous and stable screening efficiency, and reducing downtime for cleaning.

[0020] The working principle of the vibrating screen for heat treatment sandblasting process provided by this utility model is as follows: The vibrating motor 7 starts, driving the entire mounting frame 2 and its three screen boxes 6 to perform high-frequency directional vibration under the guidance and buffer of the vibration auxiliary unit 3. The mixed abrasive enters the uppermost screen box 6 from the feed pipe 5. Under the vibration screening of the large-aperture screen 9, the largest particles of material are intercepted, and the remaining material falls into the middle screen box 6 through the conveying pipe 10. In this way, the material is precisely classified according to particle size after three stages of screening. The qualified material of each stage of screening falls through the screen and into the bottom of the screen box 6 of that stage. Finally, all the fine material that passes through the lowest screen 9 is discharged uniformly from the discharge pipe 11.

[0021] During vibration, the mounting frame 2 drives the slider 33 to slide along the guide rod 31, and the spring 32 undergoes elastic deformation. The deformation force of the spring 32 reacts to the slider 33, so that the slider 33 can reciprocate along the guide rod 31, thereby allowing the screen box 6 to reciprocate back and forth.

[0022] Throughout the screening process, as the screen box 6 carries the screen 9 and moves back and forth relative to the fixed cleaning brush 43, the brush bristles continuously scrape the bottom of the screen 9, thereby effectively cleaning the particles clogging the mesh and keeping the screen unobstructed.
