Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a dust-removable shot blasting machine. Background Art

[0002] Shot blasting machine refers to casting equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of castings. The shot blasting machine can simultaneously remove sand, core and clean the castings. Nowadays, shot blasting machines are widely used in the foundry industry to remove sand and oxide scale on 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 will be generated. If a large amount of dust accumulates in the shot blasting machine for a long time and the shot blasting machine continues to operate, the dust will reattach to the workpiece and the projectile, causing pollution to the workpiece and the projectile. Therefore, it is necessary to remove the dust and debris in the shot blasting machine through a dust removal device.

[0003] When the existing dust removal device of the shot blasting machine is in use, the dust-containing gas generated by the shot blasting machine is generally sucked into the device through a fan, filtered through a filter screen in the device, and then discharged from the device.

[0004] A dust removal device for a shot blasting machine with announcement number CN214019928U comprises a main box body, a shot blasting machine body is installed on the bottom surface of the inner part of the main box body, a partition fixed to the inner part of the main box body is arranged on the right side of the shot blasting machine body, an exhaust port of the shot blasting machine body is connected with a dust guide pipe, the other end of the dust guide pipe passes through the partition and extends to the left side of the partition, a laterally arranged filter is fixed between the partition and the inner left surface of the main box body, a negative pressure fan fixed to the upper surface of the main box body is arranged on the upper side of the filter, a motor is fixed to the left side of the main box body, an output shaft of the motor is fixedly connected to a rotating rod, the other end of the rotating rod passes through the main box body and the partition in sequence and is fixed with fan blades.

[0005] The utility model can collect metal scraps and dust separately to improve utilization rate, can also dissipate heat during the production process, and can prevent the filter screen from being blocked during the filtering process.

[0006] However, when the above utility model is used to perform shot blasting on a tubular workpiece, some dust and debris will be mixed and attached to the metal shot thrown at a high speed, and some dust and debris will adhere to the workpiece. It is impossible to clean out the dust and debris mixed in the shot and attached to the workpiece after use, which will affect the subsequent reuse of the metal shot and reduce the quality of the shot blasting of the workpiece.

After the workpiece completes the shot blasting treatment under the action of the shot blasting mechanism 5 and is conveyed to the discharge bin 3 under the action of the conveying mechanism 4, the arranged electric push rod 25 is started to push and pull the control frame 26, so that the two ends of the control frame 26 move in the two movable grooves 27 respectively, and then control the cleaning frame 23 to move up and down reciprocatingly in the discharge bin 3, so that the tubular workpiece passing through the cleaning frame 23 will be brushed up and down by a plurality of cleaning brushes 24 to brush off the dust and debris on the surface of the tubular workpiece, so as to avoid the workpiece after the shot blasting treatment from adhering to the dust and debris, thereby affecting the quality of the workpiece after the shot blasting treatment, and the cleaned dust and debris can also be collected and processed by the cleaning component 8.

[0049] Optionally, the dust removal component 9 also includes a water collecting box 28 connected to the top of the water tank 12, a plurality of nozzles 29 connected to the bottom of the water collecting box 28, a water inlet pipe 30 connected to the top of the water collecting box 28, a drain pipe 31 connected to the lower end of the outer wall of the water tank 12, and a valve 32 installed on the drain pipe 31. When the air carries dust and debris into the water in the water tank 12 and initially merges with the water, some dust and debris will still escape into the water tank 12 along with the bubbles. At this time, dust-reducing water can be transported to the water collecting box 28 through the water inlet pipe 30, and then sprayed out through a plurality of nozzles 29 to perform dust reduction treatment on the dust and debris escaped in the water tank 12, thereby improving the cleaning effect of dust and debris in the air and ensuring the cleanliness of the air discharged from the exhaust port 16. Excess water can be discharged from the water outlet pipe after the valve 32 is opened.

[0051] The other ends of the several accordion plates 33 are fixedly connected to the inner wall of the discharge bin 3. When the cleaning component 8 is in use, the several accordion plates 33 can block the gap between the cleaning frame 23 and the discharge bin 3, that is, when the cleaning frame 23 moves up and down, the several accordion plates 33 are synchronously pulled back and forth or folded, and the gap between the cleaning frame 23 and the discharge bin 3 is always blocked, thereby preventing metal shots from splashing into the discharge bin 3 from the gap between the cleaning frame 23 and the discharge bin 3 when the cleaning component 8 is in use, thereby ensuring the collection effect of used metal shots; and under the cover of the several accordion plates 33, the escape of dust and debris can be reduced, thereby improving the effect of handling dust and debris.

[0052] Optionally, a dust-removable shot blasting machine also includes an isolation frame 34 fixed in the feed bin 2, and a plurality of partition curtains 35 fixedly connected to the isolation frame 34. When the workpiece is transported from the feed bin 2 to the shot blasting bin body 1 for shot blasting through the conveying mechanism 4, the workpiece will squeeze open the soft partition curtains 35, thereby achieving a certain closure between the shot blasting bin body 1 and the feed bin 2 without affecting the conveying of the workpiece, thereby reducing the dust and debris generated during the shot blasting of the workpiece from escaping from the shot blasting bin body 1 to the feed bin 2, so as to improve the comprehensiveness of the dust removal component 9 in handling dust and debris.
