Description

Technical Field

[0001] This utility model relates to the field of shot blasting technology, and in particular to a shot blasting cleaning device. Background Technology

[0002] Shot blasting technology is widely used in casting, machinery manufacturing and other fields. Its core is to remove impurities such as oxide scale or burrs by impacting the surface of the workpiece with high-speed shot. After high-speed impact, the shot may leave marks and debris on the surface of the baffle plate above the recovery structure. Traditional shot blasting equipment usually uses vibrating screens or magnetic separators to separate shot from debris. However, ordinary flat screens are prone to shot accumulation and screen hole blockage, resulting in fine debris residue and affecting shot recycling rate. Moreover, the magnetic chuck is not well matched with the shot blasting path and is easily affected by the material tilt angle during adsorption, resulting in incomplete recovery of shot and metal debris. Summary of the Invention

[0003] The present invention aims to address the shortcomings of the prior art by providing a shot blasting cleaning device.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] A shot blasting cleaning device includes a storage chamber, a lifting cylinder, a magnetic chuck, a magnetic screening box, and a primary screening screen. The lifting chamber is located above the storage chamber, with its top surface being inclined. The lifting cylinder is positioned in the middle of the lifting chamber, and its extension / retraction end is connected to the bottom of the magnetic chuck. The magnetic screening box is inclinedly positioned on the inclined top surface of the lifting chamber, with a discharge port at its inclined lower end. A discharge pipe is connected to the discharge port, passing downwards through the lifting chamber and extending into the storage chamber. The primary screening screen is inclinedly installed on the top of the magnetic screening box, and has steel ball mesh openings. A vibration motor is located at the bottom of the primary screening screen.

[0006] The storage room has a hinged side door with a handle at the bottom.

[0007] The magnetic chuck is inclinedly connected to the telescopic end of the lifting cylinder, and the inclination angle of the magnetic chuck is the same as the inclination angle of the bottom of the magnetic screening box.

[0008] A servo motor is fixed to the outer wall of the lower side of the inclined top surface of the suction cup lifting chamber. The output shaft of the servo motor is eccentrically connected to a cover plate. The side wall of the magnetic screening box is provided with an opening that matches the cover plate. The cover plate rotates at the opening to seal the discharge port.

[0009] The lower end of the primary screening mesh extends to the outside of the magnetic screening box, and a chip collection groove is provided below the primary screening mesh.

[0010] The primary screening mesh has an arc-shaped structure with a raised center, and the entire surface is provided with steel ball mesh holes, with the two side edges curving upward to form guide edges.

[0011] The height of the bulge at the high end of the inclined primary screening mesh is higher than the height of the bulge at the low end.

[0012] The beneficial effects of this utility model are as follows: This utility model adopts an arc-shaped primary screening screen with a raised center to achieve rapid stratified screening of projectiles and debris. The arc-shaped structure avoids the problem of edge accumulation of flat screens and improves screening efficiency. The matching design of the tilt angle between the magnetic screening box and the magnetic chuck ensures that the projectiles flow evenly along the inclined surface under the action of gravity. At the same time, the magnetic chuck adsorbs metal debris, preventing debris from being mixed into the projectile circulation and greatly reducing the debris residue rate.

[0016] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] A shot blasting cleaning device includes a storage chamber 1, a lifting cylinder 5, a magnetic chuck 6, a magnetic screening box 7, and a primary screening screen 12. A chuck lifting chamber 3 is arranged above the storage chamber 1, and the top surface of the chuck lifting chamber 3 is inclined. The lifting cylinder 5 is located in the middle of the chuck lifting chamber 3, and the telescopic end of the lifting cylinder 5 is connected to the bottom of the magnetic chuck 6. The magnetic screening box 7 is inclinedly arranged on the inclined top surface of the chuck lifting chamber 3. A discharge port 14 is opened at the inclined lower end of the magnetic screening box 7, and a discharge pipe 8 is connected to the discharge port 14. The discharge pipe 8 passes downward through the chuck lifting chamber 3 and extends to the storage chamber 1. The primary screening screen 12 is inclinedly installed on the top of the magnetic screening box 7. The primary screening screen 12 has steel ball mesh holes 121. A vibration motor 13 is arranged at the bottom of the primary screening screen 12.

[0019] The storage room 1 is hinged to a side-opening box door 2, and a handle 4 is provided at the bottom of the side-opening box door 2.

[0020] The magnetic chuck 6 is inclinedly connected to the telescopic end of the lifting cylinder 5, and the inclination angle of the magnetic chuck 6 is the same as the bottom inclination angle of the magnetic screening box 7.

[0021] A servo motor 9 is fixed to the outer wall of the lower side of the inclined top surface of the suction cup lifting chamber 3. The output shaft of the servo motor 9 is eccentrically connected to the cover plate 10. The side wall of the magnetic screening box 7 is provided with an opening that matches the cover plate 10. The cover plate 10 rotates at the opening to seal the discharge port 14.

[0022] The lower end of the primary screening mesh 12 extends to the outside of the magnetic screening box 7, and a chip collection groove 11 is provided below the primary screening mesh 12.

[0023] The primary screening mesh 12 has an arc-shaped structure with a raised center, and the entire surface is provided with steel ball mesh holes 121. The two side edges are raised upward to form guide edges 122.

[0024] The height of the high-end center of the inclined primary screening mesh 12 is higher than the height of the low-end center, forming a self-cleaning slope, which further prevents debris from accumulating, reduces the load on the vibration motor 13, and significantly improves operational stability.

[0025] In operation, the top surface of the suction cup lifting chamber 3 is designed as an inclined plane with an angle of 15° to 25°. The bottom surface of the magnetic screening box 7 is in the same inclination direction as the top surface of the suction cup lifting chamber 3. The diameter of the steel ball mesh 121 of the primary screening screen 12 is slightly larger than the diameter of the shot. The mixture discharged from the shot blasting machine falls into the high end of the primary screening screen 12. Because the middle of the primary screening screen 12 is raised and arc-shaped, the shot will hit the surface of the primary screening screen 12 during its fall and fall into the magnetic screening box 7. The debris larger than the mesh is trapped on the primary screening screen 12 and slides to the guide edge 122. After vibration by the vibration motor 13, the large debris is guided to the chip collection groove 11. At the same time, the lifting cylinder 5 rises to the top of the suction cup lifting chamber 3, so that the bottom of the magnetic screening box 7 has magnetic attraction. The magnetic suction cup 6 adsorbs the small debris and shot that fall into the magnetic screening box 7 onto the bottom surface of the magnetic screening box 7. The lifting cylinder 5 is activated, and the telescopic rod is retracted to lower the magnetic screening box 7. The magnetic chuck 6 separates the magnetic chuck 5 from the bottom surface of the magnetic screening box 7, reducing the magnetic attraction. The ball-type projectiles roll along the inclined bottom surface of the magnetic screening box 7 towards the discharge port 14 under the action of gravity. At this time, small debris remains on the bottom surface of the magnetic screening box 7 under the action of a smaller magnetic attraction. The servo motor 9 drives the cover plate 10 to rotate to open the discharge port 14. The projectiles flow along the discharge pipe 8 into the storage chamber 1. When all the projectiles are about to flow to the discharge port 14, the servo motor 9 drives the cover plate 10 to rotate to seal the discharge port immediately, preventing small debris from flowing out of the discharge port 14. The side-opening box door 2 is opened to remove the projectiles for collection and later use. Then, the lifting cylinder 5 is driven to continue to lower the telescopic end, making the magnetic chuck 6 separate from the bottom surface of the magnetic screening box 7 by a greater distance. After the magnetic attraction is very small, the small debris slides down the smooth bottom surface of the magnetic screening box 7 under the action of gravity. At the same time, the cover plate 10 is opened again to complete the process of collecting small debris.
