Description

Technical Field

[0001] This utility model belongs to the field of sandblasting equipment, and specifically relates to a sandblasting box body that can recycle sand. Background Technology

[0002] Sandblasting equipment is widely used in the field of rust removal. When removing rust from rusty pipes, sand is shot at high speed towards the surface of the pipe workpiece. These sand particles may be broken during the blasting process, and the broken sand forms powder. The flying sand particles can easily injure the workers, which requires the workers to wear protective clothing. Secondly, if these crushed sand materials are recycled and reused, it will affect the processing effect, and the powder will form dust when it is sprayed out again. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a recyclable sandblasting box. In use, when the engaging roller moves axially away from the driving roller, the gap between the two sleeves widens. After inserting the end of the pipe workpiece to be processed into the sleeve, the engaging roller is pushed towards the driving roller until the two sleeves clamp the two ends of the pipe workpiece. During the rotation of the engaging roller, driving roller, and pipe workpiece, sand and high-pressure airflow are input through the sandblasting pipe and air pipe. At this time, all the sandblasting nozzles spray sand downwards to achieve rust removal. Furthermore, after the sandblasting cover and observation cover are closed, the sandblasting box creates a clean environment, allowing workers to operate without wearing protective equipment, thus solving the problems mentioned in the background art.

[0004] To solve the above problems, this utility model provides the following technical solution: a recyclable sand blasting box, including a sand blasting box, a sand blasting cover plate and an observation cover plate rotatably installed at the top of the sand blasting box, a sand blasting pipe fixedly inserted into the side wall of the sand blasting cover plate, the sand blasting pipe being connected to the sand box, an air pipe connected to the side wall of the sand blasting pipe, the air pipe being connected to high-pressure air, and a sand blasting nozzle in a straight array being installed at the bottom end of the sand blasting pipe; shaft openings are provided on both the left and right side walls of the sand blasting box, a drive roller is rotatably installed inside the shaft opening on the left side, the drive roller being connected to a rotary drive mechanism, and a locking roller is rotatably installed inside the shaft opening on the right side, the locking roller having limit flanges at both ends, the locking roller being able to axially insert inside the shaft opening, and a sleeve being provided on the opposite surfaces of the drive roller and the locking roller, the two sleeves being able to lock the two ends of the pipe workpiece; a sand buffer mechanism is provided below the drive roller and the locking roller, and a screening and recycling mechanism is provided below the sand buffer mechanism.

[0005] During use, when the clamping roller moves axially away from the drive roller, the gap between the two sleeves will increase. After inserting the end of the pipe workpiece to be processed into the inside of the sleeve, the clamping roller is pushed towards the drive roller until the two sleeves clamp the two ends of the pipe workpiece. During the rotation of the clamping roller, drive roller and pipe workpiece, sand and high-pressure airflow are input into the sandblasting pipe and air pipe. At this time, all the sandblasting nozzles will spray sand downward to achieve the effect of rust removal. After the sandblasting cover plate and observation cover plate are closed, the sandblasting box forms a clean environment, and the workers can work without wearing protective equipment.

[0006] Furthermore, the sand buffer mechanism includes a first buffer plate and a second buffer plate. The first buffer plate and the second buffer plate are fixedly connected to the inner side wall of the sandblasting box, respectively. A material drop chute is provided in the side wall of the first buffer plate, and the second buffer plate is located directly below the material drop chute. A ramp plate is also provided directly below the second buffer plate, and the cross-section of the ramp plate is a right-angled triangle.

[0007] When the abrasive particles are shot downwards, they are absorbed by the impact force after hitting the first and second buffer plates. The abrasive particles on the top surface of the first and second buffer plates fall down due to vibration, which ensures that the high-speed abrasive particles will not affect the device below the sandblasting box.

[0008] Furthermore, the screening and recycling mechanism includes a screen frame and a bottom frame. The bottom frame is fixed to the bottom of the sandblasting box, and the screen frame is slidably disposed at the top of the bottom frame. Two guide rails are disposed inside the bottom frame, and a sliding groove matching the guide rails is disposed at the bottom of the screen frame. A screening nozzle is disposed on the side wall of the screen frame, and the screen frame is inclined downward toward the screening nozzle. The screening nozzle can penetrate into the interior of the rotary box. A sand pump is disposed inside the rotary box, and a trough frame is disposed at the bottom of the screen frame. A screening motor is fixedly disposed at the bottom of the sandblasting box, and a crankshaft is disposed at the output end of the screening motor. The crankshaft passes through the interior of the trough frame.

[0009] When in use, after the sand falls into the screen frame, the screening motor drives the crankshaft to rotate. The crankshaft drives the screen frame to move back and forth along the two guide rails through the slot frame. At this time, the sand powder will be screened out by the screen frame, and the large sand particles that can be recycled will fall from the screen nozzle into the interior of the rotary box.

[0010] Furthermore, a rotating card is rotatably provided on the side wall of the sandblasting box. The top of the rotating card is rotatably connected to the side wall of the sandblasting box, and the bottom of the rotating card can be pressed against the side wall of the limiting flange.

[0011] When in use, rotating the card to fit against the side wall of the limiting flange can restrict the axial movement of the clamping roller.

[0012] Furthermore, the rotary drive mechanism includes a stepper motor on the side wall of the sandblasting box, a drive wheel is provided at the output end of the stepper motor, a driven wheel is provided at the shaft of the drive roller, and the drive wheel and the driven wheel are connected by a belt winding together.

[0013] In use, the stepper motor drives the belt and driven wheel to rotate through the drive wheel. The drive roller and driven wheel rotate synchronously, and the tube workpiece between the drive roller and the clamping roller will rotate at a uniform speed.

[0014] Furthermore, the observation cover is made of glass, and the sandblasted cover is made of plastic.

[0015] During use, staff observe the sandblasting operation through glass pipe covers.

[0016] Compared with the prior art, the embodiments of this application have the following main advantages: Firstly, when the device is in use, as the clamping roller moves axially away from the drive roller, the gap between the two sleeves increases. After inserting the end of the pipe workpiece to be processed into the sleeve, the clamping roller is then pushed towards the drive roller until the two sleeves clamp the two ends of the pipe workpiece. During the rotation of the clamping roller, drive roller, and pipe workpiece, sand and high-pressure airflow are input through the sandblasting pipe and air pipe. At this time, all the sandblasting nozzles will spray sand downwards to achieve the effect of rust removal. After the sandblasting cover plate and observation cover plate are closed, the sandblasting box forms a clean environment, and the workers can work without wearing protective equipment.

[0017] Secondly, after the sand falls into the screen frame, the screening motor drives the crankshaft to rotate. The crankshaft drives the screen frame to move back and forth along the two guide rails through the slot frame. At this time, the sand powder will be screened out by the screen frame, and the large sand particles that can be recycled will fall from the screen nozzle into the interior of the rotary box.
