Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and more specifically to a dust-removing crawler shot blasting machine. Background Technology

[0002] A shot blasting machine is a casting equipment that uses high-speed shot to clean or strengthen the surface of castings. When the shot blasting machine is working, the movement of the machine's track causes the workpiece to tumble on the track. The falling shot evenly impacts the edge of the tumbling workpiece, thereby achieving the purpose of cleaning the workpiece.

[0003] During operation, existing shot blasting machines generate a large amount of debris and dust when the falling shot impacts the workpiece surface. The debris usually falls through the small holes on the track, while the dust floats in the operating chamber, adhering to the surface of the shot and clogging the small holes on the track. This not only affects the cleaning effect of the shot on the workpiece but also causes track blockage, easily leading to debris accumulation and affecting the service life of the track. Moreover, the accumulated debris and dust in the operating chamber over time on the track and shot not only increases the difficulty of subsequent cleaning but also affects the performance of the shot blasting machine. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a dust-removing track shot blasting machine that can treat the debris and dust generated during use, avoid clogging the track, and improve the service life and performance of the shot blasting machine.

[0007] To further optimize the technical solution, the slag collection trough is installed inside the cleaning box via a slide rail, and a handle is provided at the outer end of the slag collection trough to facilitate pulling it out.

[0008] To further optimize the technical solution, the water collection tank is connected to a water pipe, and a water pump is installed on the water pipe to send water from the water collection tank into the water pipe.

[0009] To further optimize the technical solution, a filter for filtering water is installed at the end of the water pipe inside the water collection tank.

[0010] To further optimize the technical solution, the internal structure of the sieve is provided with a sieve plate for sieving the projectiles, and a projectile collection box for collecting residual projectiles is provided below the sieve plate.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] A dust-removing crawler shot blasting machine, combined with Figures 1 to 2 As shown, it includes a cleaning box 1, a shot blaster 2, and an elevator 11. The cleaning box 1 is equipped with a track 16 via a roller 15 for processing workpieces. The shot blaster 2 is located above the cleaning box 1 and is used to feed shot into the cleaning box 1. The elevator 11 is located at the side of the cleaning box 1 and is used to transport the shot from the bottom of the cleaning box to the shot blaster for use.

[0020] A dust suction pipe 3 is installed on the side of the cleaning box 1 located at track 16. A fan 4 is installed on the dust suction pipe. The other end of the dust suction pipe 3 is connected to a dust collector to suck away the dust inside the cleaning box through negative pressure and send the dust into the dust collector for treatment.

[0021] A slag collection trough 10 is provided on the cleaning box 1 below the track 16 to collect the debris that falls through the small holes on the track during the cleaning process. The slag collection trough 10 is set in the cleaning box 1 by a slide rail, so that the slag collection trough can be taken out of the cleaning box for dumping. A handle is provided at the outer end of the slag collection trough 10 to facilitate pulling the slag collection trough 10 out of the cleaning box.

[0022] Three layers of guide plates 17 are arranged diagonally downwards below the exit of track 16. The lower end of the bottom guide plate corresponds to the entrance of the elevator, so that the projectiles at the exit of track can enter the entrance of the elevator through the bottom guide plate for reuse.

[0023] A water pipe 9 is installed below the slag collection trough 10, and a nozzle is installed on the water pipe to spray water onto the projectiles on the guide plate to clean the projectiles and prevent dust and debris from covering them. A water collection tank 19 is installed below the bottom guide plate 17 to collect the sprayed water. Each guide plate 17 has drainage holes to filter the sprayed water. Drainage troughs 18 are installed below the first and second guide plates 17 to collect the water that drips from the first and second guide plates, respectively, to prevent water from falling and ensuring that the projectiles at the outlet of the bottom guide plate are in a dry state. The two drainage troughs 18 are connected to the water collection tank 19 through drainage pipes 7 located on the outer wall of the cleaning box 1. The water in the drainage troughs flows directly into the water collection tank 19 through the drainage pipes 7, without affecting the drying of the projectiles below, and also realizing the collection of sprayed water.

[0024] Below the drain trough 18 is a blower pipe 5 with a blower nozzle. A blower 6 is installed on the blower pipe outside the cleaning box to blow air onto the projectiles, accelerating their drying. As the projectiles fall through the guide plate, water is sprayed onto them to wash away impurities. Then, as they fall, air is blown onto them to accelerate the drying process. Due to the multiple guide plates, the falling speed of the projectiles is slowed down, allowing sufficient contact time between the projectiles and the air blown by the blower, thus achieving surface drying for future reuse.

[0025] The water collection tank 19 is connected to the water pipe 9. A water pump 8 is installed on the water pipe to send the water in the water collection tank into the water pipe for reuse. A filter 20 is installed at the end of the water pipe 9 located in the water collection tank 19 to filter impurities in the water and prevent impurities in the water from clogging the water pipe and the nozzle.

[0026] The side wall of the water collection tank 19 is provided with a water collection tank door 22, which is used to clean the impurities in the water collection tank, and can also be used to clean and replace the filter to prevent impurities in the water from clogging the filter.

[0027] The water collection tank 19 is equipped with a water supply pipe 25, a drain pipe 23, and a level gauge 24 on its side wall. The water supply pipe is used to replenish water to the collection tank, the drain pipe is used to drain water from the collection tank, and the level gauge is used to display the liquid level information. When cleaning impurities in the collection tank, the water in the collection tank is first drained through the drain pipe before cleaning. After cleaning, water is replenished through the water supply pipe. During use, the water level in the collection tank is observed through the level gauge. When the water level is low, water is replenished in time to facilitate the cleaning of projectiles.

[0028] The elevator 11 is equipped with a shot conveying auger 21 to transport the shot from the bottom to the top. A screen 13 is installed between the outlet end of the elevator and the inlet end of the shot blaster 2 to screen the shot. A screening plate 14 is installed horizontally inside the screen 13 to screen the shot. A shot collection box 12 is installed below the screening plate 14 to collect the screened residual shot. The outlet end of the screening plate 14 is connected to the inlet end of the shot blaster through a pipe to send qualified shot into the shot blaster for use.

[0029] In operation, the shot blaster throws shot into the cleaning box, where it collides with the workpiece on the track to clean it. During the cleaning process, debris falls from the small holes on the track into the slag collection trough. The generated dust is sucked into the dust collector through the suction pipe for treatment. Shot falling from the track outlet is washed by water sprayed from the nozzles as it passes the guide plate. The washed water enters the drain trough and then flows through the drain pipe into the water collection tank at the bottom for recycling. The shot is dried by air blowing as it passes the second and third guide plates. The dried shot is then conveyed to the top by the shot conveyor auger in the elevator, where it is screened to remove damaged shot. Qualified shot enters the shot blaster for reuse.
