Description

Technical Field

[0001] The utility model relates to the field of sandblasting machines, in particular to a sandblasting machine with a protective dust removal structure. Background Art

[0002] A sandblasting machine is a device used for surface treatment and processing. It cleans, removes paint, rusts, or polishes the surface of a workpiece by spraying abrasive particles at high speed. Its main working principle is to use compressed air to spray abrasives such as steel grit, brown corundum, quartz sand, etc. at high speed onto the surface of the object being treated. The surface treatment effect is achieved through the impact of the abrasive. After sandblasting, the sandblasting machine will generate a large amount of dust inside the sandblasting machine, which requires a corresponding dust removal structure to remove the dust. Existing sandblasting machines usually use bag dust removal to adsorb dust on the bag during use. However, due to the thickening of the bag's adsorption layer, the bag needs to shake the dust into the ash hopper through pulse shaking. At the same time, some lighter dust will diffuse back into the sandblasting machine and be adsorbed into the human body when the worker turns on the sandblasting machine, endangering the worker's health. Therefore, we propose a sandblasting machine with a protective dust removal structure to solve the above-mentioned problems. Utility Model Content

The dust leakage holes 17 are concentrically arranged with the middle through hole 505.

[0025] See also Figure 1-5In this embodiment, the dust removal component 5 includes a filter cartridge 501 and an adsorption plate 503. The filter cartridge 501 is provided with two groups. The two groups of filter cartridges 501 are symmetrically arranged along the interior of the dust removal bin 4. The outer end of the filter cartridge 501 is provided with an adsorption ring groove 502. The adsorption plate 503 is provided with multiple groups. The multiple groups of adsorption plates 503 are arranged around the interior of the adsorption ring groove 502. The center of the filter cartridge 501 is provided with a hollow frame 504. The center of the hollow frame 504 is penetrated by a middle through hole 505. By combining the two groups of filter cartridges 501, compared with the previous equipment using bag dust removal, the suction force generated by the dry suction device 507 is transmitted to the outside through the hollow groove 19, so that the dust floating in the air is removed. Under the traction of suction, part of the dust is adsorbed by the adsorption plate 503, and part passes through the hollow skeleton 504 and enters the middle through hole 505 to be concentrated, so that the dust floating in the sandblasting chamber 8 and the dust removal chamber 4 can be basically effectively removed, thereby avoiding the problem that after the sandblasting machine uses a bag to adsorb dust, the dust layer in the bag is too thick and the dust is diffused into the sandblasting machine in the reverse direction. A cover plate 506 is provided to match the middle through hole 505. The cover plate 506 is located at the center of the upper end of the filter cartridge 501. A suction hole 509 is opened in the center of the cover plate 506. A dry suction device 507 (the model of the dry suction device 507 is 5890 Series) is provided between the two sets of filter cartridges 501. II GC), a suction square tube 508 is provided at the top of the dry aspirator 507, one end of the suction square tube 508 is connected to the dry aspirator 507, and the other end of the suction square tube 508 extends to the interior of the suction hole 509. A filter is provided inside the suction hole 509. The dry aspirator 507 and the suction square tube 508 are combined through the cover plate 506, so that the dry aspirator 507 can transmit suction force to the filter cartridge 501 through the suction square tube 508. At the same time, the filter can prevent dust from entering the dry aspirator 507 during suction, and the cover plate 506 can prevent the dust in the dust box sandblasting machine in the middle through hole 505 from diffusing back.

[0026] When working, the staff first puts the workpiece into the sandblasting chamber 8, then presses the control switch 14 to make the control module 13 control the sandblasting structure 3 to work, and then observes the sandblasting completion of the workpiece from the observation window 10 and makes adjustments. When making adjustments, the staff puts their hands into the protective gloves 20 and adjusts the angle position of the sandblasted workpiece according to needs outside the sandblasting machine, and uses the protective gloves 20 to protect their hands from being injured by sandblasting.

[0027] After the sandblasting is completed, the staff presses the control switch 14 to make the control module 13 control the dry suction device 507 to start. The dry suction device 507 transmits the suction force to the filter cartridge 501 through the suction square tube 508. The suction force generated by the dry suction device 507 is transmitted to the outside through the hollow groove 19, so that the dust floating in the air is pulled by the suction force. Part of it is adsorbed by the adsorption plate 503, and part of it passes through the hollow skeleton 504 and enters the middle through hole 505 and is concentrated, so that the floating dust in the sandblasting chamber 8 and the dust removal chamber 4 can be basically effectively removed.

[0028] Then, the dry type suction device 507 is turned off. When the dry type suction device 507 stops working, the dust collected in the middle through hole 505 enters the dust collecting drawer 16 through the dust leakage hole 17 and is collected and processed.

[0029] According to the above steps, after the sandblasting is completed, the suction force generated by the dry suction device 507 is transmitted to the outside through the hollow groove 19, so that the dust floating in the air is pulled by the suction force, and part of it is adsorbed by the adsorption plate 503, and part of it passes through the hollow skeleton 504 and enters the middle through hole 505 to be concentrated. When the dry suction device 507 stops working, the dust concentrated in the middle through hole 505 enters the dust collection drawer 16 from the dust leakage hole 17 to be collected and processed.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
