Description

Technical Field

[0001] The present utility model relates to the field of sandblasting machines, and specifically to a sand particle recovery and cleaning mechanism for a sandblasting machine. Background Art

[0002] In many industries such as metal manufacturing, machining, construction, and automotive repair, sandblasting is a commonly used surface treatment technology. However, during the use of a sandblasting machine, although the sand particles can be recycled, there will be some iron filings left after each sandblasting. If these iron filings are not removed in time, it will affect the subsequent sandblasting effect. Content of the Utility Model

[0003] In order to overcome the above deficiencies, the present utility model provides a sand particle recovery and cleaning mechanism for a sandblasting machine.

[0004] The technical solution adopted by the present utility model is as follows:

The sliding strips are fixedly connected with the inner wall of the adsorption box. The inner side of the top surface of the sliding strip is inclined downward. Adsorption components are inserted into the front socket and the side socket.

[0006] The adsorption component includes a baffle and an insertion plate. The insertion plate is located inside the adsorption box and is slidably matched with the sliding strip.

Specific embodiments

[0014] As Figures 1-3 shown: A sand particle recovery and cleaning mechanism for a sandblasting machine includes a sandblasting machine 1. The bottom of the box body of the sandblasting machine 1 is fixedly communicated with a feeding hopper 2. The bottom of the feeding hopper 2 is fixedly communicated with an adsorption box 3. Both the top and bottom of the adsorption box 3 are open. The bottom of the adsorption box 3 is fixedly communicated with a temporary storage box 4. The bottom of the temporary storage box 4 is fixedly communicated with a sand discharge pipe 5. A valve is installed on the sand discharge pipe 5. The bottom outer wall of the temporary storage box 4 is fixedly communicated with a sand conveying pipe 6. The other end of the sand conveying pipe 6 extends into the sandblasting machine 1. Front sockets 7 are respectively opened at the top and bottom of the front side wall of the adsorption box 3. A side socket 8 is opened in the middle of the right side wall of the adsorption box 3. Vertical sliding strips 15 are respectively fixedly connected to the two bottom corners at the rear side of the front socket 7 and the two bottom corners on the left side of the side socket 8. The sliding strips 15 are fixedly connected to the inner wall of the adsorption box 3. The inner side of the top surface of the sliding strip 15 is inclined downward. Adsorption components are inserted into both the front socket 7 and the side socket 8.

[0015] The top surface of the sliding strip 15 is designed to be inclined, so that the sand material will not fall on the sliding strip 15, avoiding waste of sand material.

[0016] The adsorption component includes a baffle 9 and an inserting plate 10. The inserting plate 10 is located inside the adsorption box 3 and is slidably matched with the sliding strip 15. A magnetic bar 11 is fixedly connected between the opposite side walls of the baffle 9 and the inserting plate 10. The upper and lower rows of the magnetic bars 11 are staggered. A handle 12 is fixedly connected to the outer wall of the baffle 9. Hooks 13 are respectively fixedly connected to both the left and right side walls of the baffle 9. The hooks 13 face the outer wall of the adsorption box 3. A fixing strip 14 adapted to the hooks 13 is fixedly connected to the outer wall of the adsorption box 3.

[0017] The left and right ends of the inserting plate 10 are bent at a right angle towards the baffle 9.

[0018] Due to the fact that the two ends of the inserting plate 10 are bent at a right angle towards the baffle 9, this design helps to insert the adsorption component onto the sliding strip 15 more smoothly.

[0019] When the sandblasting operation is carried out in the sandblasting machine 1, sand grains flow into the feeding hopper 2 through the bottom of the box body and then enter the adsorption box 3.

[0020] After the sand grains and the possibly mixed iron impurities enter the adsorption box 3 together, due to the existence of the adsorption component, these sand grains and impurities will undergo a separation process. Specifically, when the sand grains and impurities fall from top to bottom inside the adsorption box 3, they will encounter a magnetic field region composed of magnetic rods 11. Since the magnetic rods 11 are staggered, their strong magnetic field can adsorb the iron impurities mixed in the sand grains.

[0021] The iron impurities adsorbed by the magnetic rods 11 will adhere to the magnetic rods 11, while the unadsorbed sand grains will continue to fall, be temporarily stored in the temporary storage box 4, and finally be discharged through the sand discharge pipe 5 (when the valve is opened), or returned to the sandblasting machine 1 through the sand conveying pipe 6 for recycling.

[0022] As the usage time increases, the iron impurities adsorbed on the magnetic rods 11 will gradually increase. At this time, the staff can easily pull out the baffle 9 together with the plug board 10 from the adsorption box 3 through the handle 12. After being pulled out, the impurities on the magnetic rods 11 can be cleaned by using external tools, or the entire adsorption component can be directly replaced with a new one. After cleaning or replacement, the adsorption component is reinserted into the adsorption box 3 and fixed by the cooperation of the hook 13 and the fixing strip 14.
