Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically to a dust removal device for shot blasting machines. Background Technology

[0002] A shot blasting machine is a casting equipment that uses high-speed shot blasting to clean or strengthen the surface of castings. Shot blasting machines can simultaneously remove sand, cores, and clean castings. Nowadays, shot blasting machines are widely used in the foundry industry to remove sand and oxide scale from the surface of cast steel and cast iron parts. When using a shot blasting machine to blast workpieces, a large amount of dust and debris is generated. If a large amount of dust accumulates in the shot blasting machine for a long time and continues to operate with the shot blasting machine, the dust will re-adhere to the workpiece and shot, causing contamination to the workpiece and shot. Therefore, it is necessary not only to remove dust during the shot blasting process, but also to remove dust from the surface of the shot after shot blasting.

[0003] A patent for a dust removal device for a shot blasting machine, with announcement number CN217594124U, includes a base, a dust collection box fixedly connected to the top of the base, a vacuum cleaner fixedly connected to the left side of the dust collection box, the output end of the vacuum cleaner fixedly connected to the left side of the dust collection box, a filter screen fixedly connected inside the dust collection box, and a power box fixedly connected to the top of the dust collection box. This invention has a reasonable structure and simple operation. A moving component allows the cleaning brush to adhere to the surface of the filter screen, a first motor allows the cleaning brush to rotate, and the power component allows the cleaning brush to move longitudinally back and forth. This allows for cleaning of the filter screen without disassembling it, achieving the purpose of convenient filter screen cleaning.

[0004] However, during the shot blasting process of the workpiece using the shot blasting machine in this patent, some dust and debris will also be mixed in with the high-speed shot. It is impossible to clean out the dust and debris mixed in with the shot after use. The shot after use contains a large amount of metal dust and particulate matter, which affects the subsequent use of shot.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0023] like Figures 1 to 4As shown, this utility model discloses a dust removal device for a shot blasting machine, comprising: a dust removal box 1; a dust removal filter cartridge 2 rotatably mounted on the dust removal box 1 for removing dust from the surface of shot blasting steel balls; sealed bearings on both sides of the dust removal filter cartridge 2, with the inner ring of the sealed bearing fixedly connected to the surface of the dust removal filter cartridge 2 and the outer ring of the sealed bearing fixedly connected to the interior of the dust removal box 1; the sealed bearings improve the sealing performance of the dust removal box 1 and enhance the rotational stability of the dust removal filter cartridge 2; a transmission assembly 3 for driving the rotation of the dust removal filter cartridge 2; an industrial vacuum cleaner 4 fixedly mounted on the dust removal box 1; the suction end of the industrial vacuum cleaner 4 fixedly mounted at the bottom of the dust removal box 1; and by activating the industrial vacuum cleaner 4, the dust removed from the interior of the dust removal filter cartridge 2 is removed. Waste is sucked into the industrial vacuum cleaner 4 for collection. The dust collection component 5 and the detachable sealing head 6 are installed on the dust collection filter cartridge 2 to collect dust from the surface of the shot blasting steel balls inside the dust collection filter cartridge 2. The sealing head 6 is fixed to the end of the dust collection filter cartridge 2 by threaded installation. After unscrewing the sealing head 6 from the end of the dust collection filter cartridge 2, the shot blasting steel balls to be dusted are placed inside the dust collection filter cartridge 2. Then the sealing head 6 is screwed back on to complete the filling of the shot blasting steel balls. The gear 302 at the output end of the motor 303 drives the gear ring 301 at the end of the dust collection filter cartridge 2 to mesh and rotate, causing the shot blasting steel balls inside the dust collection filter cartridge 2 to turn over. This causes the metal dust attached to the surface of the steel balls to be screened out from the filter holes on the surface of the dust collection filter cartridge 2, and the dust is collected by the industrial vacuum cleaner 4.

[0024] The transmission assembly 3 includes: a gear ring 301 fixedly mounted on the dust collector filter cartridge 2, a gear 302 meshing with the surface of the gear ring 301, and a motor 303 driving the gear 302 to rotate. The motor 303 is preferably a servo motor.

[0025] The dust collection assembly 5 includes: electromagnets 501 fixedly installed on both sides inside the dust collection box 1, normally closed switch contacts 502 fixedly installed on the dust collection box 1, and electromagnets 501 and normally closed switch contacts 502 electrically connected. When the protrusion 503 is not pressing against the normally closed contact of the normally closed switch contact 502, the electromagnet 501 is in a magnetic attraction state, so that the electromagnets 501 symmetrically installed on both sides of the dust collection filter cartridge 2 can adsorb the metal waste shavings screened out in the dust collection filter cartridge 2 to accelerate the separation of metal waste shavings on the shot blasting steel balls, and a protrusion 503 fixedly installed on the dust collection filter cartridge 2 to match the normally closed switch contacts 502. The protrusion 503 is semi-circular. When the output end of the motor 303 drives the gear 302 to mesh and rotate with the gear ring 301 fixed at one end of the dust collector filter cartridge 2, when the protrusion 503 on the surface of the dust collector filter cartridge 2 rotates and presses against the normally closed contact of the normally closed switch contact 502, the electromagnet 501 is in the de-energized state. The metal dust particles adsorbed on the surface of the electromagnet 501 automatically fall into the bottom of the dust collector box 1 and are collected by the industrial vacuum cleaner 4, realizing the automatic cleaning of metal waste on the surface of the electromagnet 501 and avoiding excessive metal waste adsorbed on the surface of the electromagnet 501 from affecting the magnetic attraction effect.

[0026] A brush plate 5011 is fixedly installed on one side of the electromagnet 501, and the surface of the brush plate 5011 rests on the surface of the dust collector filter cartridge 2. The length of the brush plate 5011 is equal to the width of the filter section in the middle of the dust collector filter cartridge 2. As the dust collector filter cartridge 2 rotates, the brush plate 5011 sweeps the surface of the dust collector filter cartridge 2, reducing the problem of filter pore clogging.

[0027] Working Principle: After the shot blasting machine's steel balls finish processing the workpiece upon power connection, the used steel balls need to be dusted. Otherwise, when the steel balls are used again, the surface metal dust and particles will re-adhere to the workpiece, causing contamination and affecting the workpiece's surface gloss and quality. Therefore, by unscrewing the sealing head 6 from the end of the dust collector filter cartridge 2, placing the steel balls to be dusted inside the dust collector filter cartridge 2, and then screwing the sealing head 6 back on to complete the filling of the steel balls, the gear 302 at the output end of the motor 303 drives the gear ring 301 at the end of the dust collector filter cartridge 2 to rotate, causing the steel balls inside the dust collector filter cartridge 2 to tumble. This allows the metal dust adhering to the surface of the steel balls to be screened out through the filter holes on the surface of the dust collector filter cartridge 2. Dust is collected by the industrial vacuum cleaner 4. During the dust removal and filtration of shot blasting steel balls in the dust removal filter cartridge 2, when the protrusion 503 is not pressed against the normally closed contact 502, the electromagnet 501 is in a magnetic attraction state, which can adsorb the metal waste sifted out in the dust removal filter cartridge 2 to accelerate the separation of metal waste sifting from the shot blasting steel balls. When the protrusion 503 on the surface of the dust removal filter cartridge 2 rotates and presses against the normally closed contact 502, the electromagnet 501 is in a de-energized state. The metal dust particles adsorbed on the surface of the electromagnet 501 automatically fall into the bottom of the dust collection box 1 and are collected by the industrial vacuum cleaner 4, realizing the automatic cleaning of metal waste sifting on the surface of the electromagnet 501 and avoiding excessive metal waste sifting adsorbed on the surface of the electromagnet 501 from affecting the magnetic attraction effect.
