Description

Technical Field

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

[0002] A shot blasting machine is a casting equipment that uses high-speed shot projectiles to clean or strengthen the surface of castings. Shot blasting machines can simultaneously remove sand, cores, and clean castings; in some regions, they are also colloquially called sandblasting machines or blasting machines.

[0003] For example, a shot blasting machine for steel pipe production, with announcement number CN221390603U and announcement date of July 23, 2024, includes a main body and a fixed mechanism. The fixed mechanism is located above the main body. The main body includes a base, a processing chamber, a fixed chamber, a motor, a rotating rod, and a grinding machine. The processing chamber is fixedly installed at the front end of the upper end of the base, and the fixed chamber is fixedly installed at the rear end of the upper end of the base. The motor is movably installed at the inner end of the processing chamber, the rotating rod is movably installed at the right end of the motor, and the grinding machine is movably installed at the right end of the rotating rod. The main body also includes a waste material handling component, support feet, anti-slip and shock-absorbing pads, a controller, and an output port. The waste material handling component is movably installed at the lower end of the inner end of the processing chamber.

[0004] When steel pipes rust, shot blasting machines are used to blast fine steel shot to remove the rust. However, during rust removal, the impact of the steel shot generates rust dust, which floats inside the shot blasting machine and then drifts to the outside, causing air pollution and even harming the health of workers. Therefore, there is an urgent need to design a dust removal mechanism for shot blasting machines to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a dust removal mechanism for a shot blasting machine to address the aforementioned shortcomings in the prior art.

The output end of the vacuum motor 13 is equipped with a vacuum fan 14, and the output end of the vacuum motor 13 is connected to the top of the cleaning rod 16. The outer walls of the mechanism housing 1 and the dust collection box 10 are equipped with a vacuum pipe 9, and the inner wall of the top of the mechanism housing 1 is equipped with a coarse filter screen 18. The vacuum motor 13 is a servo motor. The vacuum motor 13 drives the vacuum fan 14 to rotate, and the vacuum fan 14 generates suction, which causes the floating dust inside the mechanism housing 1 to enter the dust collection box 10 through the vent 17 and the vacuum pipe 9, thus realizing the function of collecting floating dust.

[0028] The system is configured such that the vacuum motor 13 drives the vacuum fan 14 to rotate, generating suction in the vacuum cylinder 12. This suction draws rust-removing dust into the dust collection box 10 through the vent 17 and the vacuum pipe 9. The sealing cover 11 seals the dust collection box 10, thus achieving the function of vacuuming dust inside the outer shell 1. The cleaning rod 16 rotates and sweeps away dust adhering to the protective net 15, preventing dust from clogging the protective net 15 and affecting the suction power. This ensures that the dust inside the outer shell 1 is collected, preventing dust from floating into the outside environment, polluting the atmosphere, and harming the health of the workers.

[0029] In one embodiment of this utility model, such as Figure 1 and Figure 2As shown, a dust-generating fan 19 is fixed to the outer wall of the housing 1 by bolts, and a collection box 20 is slidably connected to the outer wall of the housing 1. The dust-generating fan 19 generates blowing force, causing the raised dust to be blown into the housing 1.

[0030] In another embodiment provided by this utility model, such as Figure 2 As shown, a stirring motor 22 is fixed to the outer wall of the bottom of the collection box 20 by bolts, and a dust-raising rod 23 is provided at the output end of the stirring motor 22. A fine filter screen 21 is provided on the outer wall of the collection box 20.

The rotating rod 6 rotates on the bracket 2, and the bracket 2 has the function of limiting the rotation of the rotating rod 6.

[0032] In one embodiment provided by this utility model, such as Figure 3 As shown, the outer wall of the rotating rod 6 is provided with a rotating wheel 7 and a soft cleaning wheel 8, and one end of the rotating rod 6 is provided with a standard gear 4. The rotating rod 6 drives the rotating wheel 7 and the soft cleaning wheel 8 to rotate, so that the steel pipe 28 can rotate and be cleaned.

[0033] In another embodiment provided by this utility model, such as Figure 2 As shown, a rotating motor 3 is fixed to the inner wall of the bracket 2 by bolts, and the output end of the rotating motor 3 is connected to the outer wall of the standard gear 4. The outer walls of the two standard gears 4 are meshed with chains 5, and the outer walls of the two rotating wheels 7 are provided with steel pipes 28. The rotating motor 3 drives the standard gears 4 to rotate, and the standard gears 4 mesh with the chains 5 to rotate, so that the two rotating rods 6 can rotate, and the steel pipes 28 can rotate on the bracket 2.

The ring 26 moves on the sliding rod 25, and the ring 26 drives the folding curtain 27 to move, which realizes the function of shielding the outer casing 1 of the mechanism and avoids the problem of some floating dust drifting out from the inside of the mechanism.

[0035] Working principle: In use, the steel pipe 28 is placed on the rotating wheel 7 on the bracket 2. The rotating motor 3 is started, which drives one of the standard gears 4 to rotate. The standard gear 4 is driven by the chain 5, which drives the rotating rod 6 to rotate. The rotating rod 6 drives the rotating wheel 7 and the soft cleaning wheel 8 to rotate, so that the steel pipe 28 can rotate automatically when removing rust, thus removing rust from the surface of the steel pipe 28. The soft cleaning wheel 8 sweeps away the floating dust attached to the steel pipe 28. The vacuum motor 13 is started, which drives the vacuum fan 14 to rotate. The vacuum fan 14 generates suction, which draws the floating dust inside the outer shell 1 of the mechanism through the vacuum. Pipe 9 and vent 17 enter the dust collection box 10, realizing the function of collecting the floating dust from rust removal, preventing the floating dust from floating to the outside environment and polluting the environment, and harming the health of the workers. After the work, the floating dust mixed with steel shot falls into the collection box 20. The stirring motor 22 is started, and the stirring motor 22 drives the dust-raising rod 23 to rotate, causing the floating dust mixed with steel shot to be raised. The dust-raising fan 19 is started, and the dust-raising fan 19 generates blowing force. The blowing force passes through the fine filter screen 21 and blows the raised floating dust into the outer shell 1 of the mechanism, and then enters the dust collection box 10 through the suction pipe 9 and vent 17, realizing the function of separating steel shot and floating dust, and realizing the function of secondary reuse of steel shot.
