Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 4 and Figure 5 An embodiment of this utility model is provided: a belt-type sandblasting room, including a sandblasting chamber 1, a support 2 is provided at the front right end of the sandblasting chamber 1, a conveying mechanism 3 is provided at the bottom of the sandblasting chamber 1, the conveying mechanism 3 is used to collect used sandblasting shot, a dust removal mechanism 4 is provided at the front of the sandblasting chamber 1, the dust removal mechanism 4 is used to remove dust inside the device, and an auxiliary mechanism 5 is provided inside the sandblasting chamber 1.

[0034] The conveying mechanism 3 includes a fixed frame 31, the top of which is located at the bottom right side of the sandblasting chamber 1. A housing 32 is fixedly connected to the inner side of the fixed frame 31. A motor 33 is fixedly connected to the rear right side of the housing 32. A spiral shaft 34 is fixedly connected to the front side of the motor 33. A lifting machine 35 is located at the front side of the fixed frame 31. Multiple belt conveyors 36 are located at the top of the fixed frame 31. A recycling assembly 37 is located at the bottom inner side of the sandblasting chamber 1. The recycling assembly 37 includes multiple recycling hoppers 371, the bottom of which are fixedly connected to... At the bottom inner side of the sandblasting chamber 1, a grid 372 is fixedly connected to the top of multiple recovery hoppers 371. A control component 38 is provided on the front side of the sandblasting chamber 1. The control component 38 includes a control console 381. The rear side of the control console 381 is located on the front side of the sandblasting chamber 1. Multiple buttons 382 are fixedly connected to the top of the control console 381. A sandblasting component 39 is provided on the inner side of the support 2. The sandblasting component 39 includes a shot blasting tank 391. The top of the shot blasting tank 391 is located on the inner side of the support 2. A separator 392 is fixedly connected to the top of the support 2.

[0035] Specifically, the sandblasting chamber 1 provides a closed space for sandblasting operations, the support frame 2 supports the sandblasting components 39, the conveying mechanism 3 completes the recovery and conveying of sandblasting shot, the dust removal mechanism 4 purifies the internal environment, and the auxiliary mechanism 5 works together to improve operating efficiency and ensure the stable operation of sandblasting operations.

[0036] When the conveying mechanism 3 is working, the used sandblasting shot generated by the sandblasting operation falls to the recovery component 37 at the bottom of the inner side of the sandblasting chamber 1. Multiple recovery buckets 371 receive the falling sandblasting shot. The grid 372 on the top of the recovery bucket 371 provides a place for the workers to stand. The sandblasting shot falls through the holes of the grid 372. The sandblasting shot in the recovery bucket 371 slides to multiple belt conveyors 36 on the top of the fixed frame 31. Through the cooperation of the recovery bucket 371 and the belt conveyor 36, the sandblasting shot is transported to the surface of the belt conveyor 36. The belt conveyor 36 drives the sandblasting shot to move towards the outer shell 32 inside the fixed frame 31. Through the cooperation of the belt conveyor 36 and the outer shell 32, the sandblasting shot is transported into the interior of the outer shell 32.

[0037] The motor 33 on the right rear side of the outer casing 32 starts, and the motor 33 drives the front spiral shaft 34 to rotate. During the rotation of the spiral shaft 34, it pushes the sandblasting shot inside the outer casing 32 to move towards the elevator 35 on the front side of the fixed frame 31. Through the cooperation of the motor 33 and the spiral shaft 34, the power is provided for the sandblasting shot to be transported. Through the cooperation of the spiral shaft 34 and the outer casing 32, the sandblasting shot is ensured to move stably along the inside of the outer casing 32, avoiding the sandblasting shot from accumulating and clogging. After receiving the sandblasting shot transported by the spiral shaft 34, the elevator 35 lifts the sandblasting shot to the separator 392 at the top of the bracket 2. Through the cooperation of the elevator 35 and the separator 392, the vertical transport of the sandblasting shot is realized, preparing for the recycling of the sandblasting shot.

[0038] The shot blasting tank 391 inside the support 2 stores the sandblasting shot to be used. The separator 392 performs secondary separation on the sandblasting shot conveyed by the elevator 35 to remove the small impurities remaining in the sandblasting shot. Through the cooperation of the separator 392 and the shot blasting tank 391, the qualified sandblasting shot after separation is conveyed into the shot blasting tank 391 to realize the recycling of the sandblasting shot. During the sandblasting operation, the sandblasting shot in the shot blasting tank 391 is sprayed onto the surface of the workpiece to be treated inside the sandblasting chamber 1 through the sandblasting component 39 inside the support 2 to complete the sandblasting process.

[0039] The control component 38 on the front side of the sandblasting chamber 1 is used to control the operation of the equipment. The operator sends commands through multiple buttons 382 on the top of the control console 381 to control the start and stop of the motor 33, the hoist 35, the belt conveyor 36 and the sandblasting component 39. Through the cooperation of the buttons 382 and the control console 381, the operating status of the equipment can be conveniently adjusted.

[0040] Reference Figure 1 , Figure 2 and Figure 3The dust removal mechanism 4 includes multiple fans 41. The rear side of each fan 41 is fixedly connected to the front side of the sandblasting chamber 1. The front side of each fan 41 is fixedly connected to an air duct 42. The top of each air duct 42 is fixedly connected to a dust collector 43. The front side of the sandblasting chamber 1 is fixedly connected to a ventilation pipe 44.

[0041] Specifically, when the dust removal mechanism 4 is working, the dust generated inside the sandblasting chamber 1 by the sandblasting component 39 spraying sandblasting shot forms an airflow channel through the ventilation pipe 44 on the front side of the sandblasting chamber 1. The ventilation pipe 44 is connected to the inside of the sandblasting chamber 1. Through the cooperation of the ventilation pipe 44 and the sandblasting chamber 1, a path is provided for the flow of dust, ensuring that the dust can smoothly gather towards the dust removal mechanism 4. The operator sends a command through the button 382 on the top of the control console 381 of the control component 38 to start multiple fans 41. The operation of the fans 41 generates negative pressure suction. Through the cooperation of the fans 41 and the ventilation pipe 44, the dust-laden air inside the sandblasting chamber 1 is sucked into the rear of the fans 41. Then, the fans 41 transport the dust-laden air to the air duct 42 fixedly connected to the front. Through the cooperation of the fans 41 and the air duct 42, the directional transport of dust-laden air is achieved, preventing dust from spreading to the external environment of the sandblasting chamber 1.

[0042] Dust-laden air is guided by duct 42 to a dust collector 43 fixedly connected at the top. After entering the dust collector 43, the dust collector 43 filters and separates the dust particles in the air. Through the cooperation of duct 42 and dust collector 43, it is ensured that the dust-laden air can completely enter the processing area of ​​dust collector 43, avoiding the direct discharge of some dust-laden air without treatment. Dust collector 43 discharges the filtered clean air and collects the separated dust and impurities at the same time. Through the processing function of dust collector 43, the dual effects of air purification and dust collection are achieved. Through the cooperation of dust collector 43 and duct 42, it is ensured that the purified air meets the emission requirements, and the collected dust is convenient for subsequent centralized treatment.

[0043] Reference Figure 1 , Figure 3 and Figure 4 The auxiliary mechanism 5 includes a safety door 51, the outer side of which is located at the rear of the sandblasting chamber 1. A lifting door 52 is located on the right side of the sandblasting chamber 1. The auxiliary mechanism 5 also includes multiple lighting lamps 53, the outer sides of which are fixedly connected to the inner side of the sandblasting chamber 1. The irradiation surfaces of the multiple lighting lamps 53 are all made of polymethyl methacrylate explosion-proof material. The auxiliary mechanism 5 also includes two operating platforms 54, the outer sides of which are fixedly connected to the front and rear ends of the inner side of the sandblasting chamber 1, respectively. The two operating platforms 54 are symmetrically distributed on the inner side of the sandblasting chamber 1.

[0044] Specifically, when the auxiliary mechanism 5 is working, before the sandblasting operation begins, the workpiece to be processed needs to be sent into the sandblasting chamber 1. At this time, the lifting door 52 on the right side of the sandblasting chamber 1 can be operated. Through the cooperation of the lifting door 52 and the sandblasting chamber 1, the passage on the right side of the sandblasting chamber 1 is opened. The operator and the conveying equipment can transport the workpiece to the surface of the belt conveyor 36 of the conveying mechanism 3. After the workpiece is placed, the lifting door 52 is closed. Through the cooperation of the lifting door 52 and the sandblasting chamber 1, the sandblasting chamber 1 is sealed to prevent sandblasting shot and dust from leaking from the right side during the sandblasting operation.

[0045] If personnel need to enter the sandblasting chamber 1 for inspection and adjustment during the sandblasting operation, the sandblasting assembly 39, conveying mechanism 3 and dust removal mechanism 4 must be stopped first through the control console 381 of the control component 38. Then, the safety door 51 at the rear of the sandblasting chamber 1 is opened. The safety door 51 and the sandblasting chamber 1 work together to form a personnel access passage. After the personnel enter, the safety door 51 is closed. The safety door 51's own protective structure prevents injury to personnel when the equipment is accidentally started, thus ensuring the safety of personnel during operation.

[0046] When sandblasting is carried out, multiple lights 53 inside the sandblasting chamber 1 are activated. Through the cooperation of the lights 53 and the sandblasting chamber 1, the interior of the sandblasting chamber 1 is illuminated, allowing clear observation of the sandblasting situation on the workpiece surface and the operating status of the equipment. This facilitates timely adjustment of the sandblasting angle and parameters. The illumination surface of the lights 53 is made of a specific explosion-proof plate material. Through the material properties of the lights 53 and their cooperation with the sandblasting chamber 1, the impact of sandblasting shot and dust adhesion are prevented from affecting the lighting effect, ensuring the stable operation of the lighting function.

[0047] When operators need to adjust the spraying position of the sandblasting component 39 and check the sandblasting quality of the workpiece at close range, they can stand on the operating platform 54 at the front and rear ends inside the sandblasting chamber 1. Through the cooperation between the operating platform 54 and the sandblasting chamber 1, a stable standing support is provided for the operator. The two operating platforms 54 are symmetrically distributed. Through the position layout of the operating platforms 54, it is ensured that the operator can cover the operation needs of different areas inside the sandblasting chamber 1.

[0048] Working principle: The auxiliary mechanism 5 and the conveying mechanism 3 are prepared for operation. The lifting door 52 on the right side of the sandblasting chamber 1 is operated. The lifting door 52 and the sandblasting chamber 1 are cooperated to open the channel and transport the workpiece to be processed to the surface of the belt conveyor 36 of the conveying mechanism 3. The lifting door 52 is closed to seal the sandblasting chamber 1. If personnel adjustment is required, the relevant mechanism is stopped by the button 382 on the top of the control console 381 of the control component 38. The safety door 51 on the rear side of the sandblasting chamber 1 is opened. After the personnel enter, the safety door 51 is closed. They stand on the grid 372 of the recovery component 37 to operate. After the operation is completed, the equipment is restored to standby state.

[0049] Press button 382 on top of console 381 to start sandblasting assembly 39, conveying mechanism 3 and dust removal mechanism 4. Sandblasting assembly 39 releases sandblasting shot from shot blasting tank 391 and sprays it onto the surface of workpiece on belt conveyor 36 to complete sandblasting. At the same time, lighting 53 of auxiliary mechanism 5 is turned on, and lighting is provided by the cooperation of lighting 53 and sandblasting chamber 1. The operator can stand on operating platform 54 to adjust the spraying position of sandblasting assembly 39 and check the sandblasting quality of workpiece.

[0050] The conveying mechanism 3 recovers the sandblasting shot. The used sandblasting shot falls into the recovery hopper 371 at the bottom of the inner side of the sandblasting chamber 1. It enters the recovery hopper 371 through the holes of the grid 372. Through the cooperation of the recovery hopper 371 and the belt conveyor 36, it slides down to the belt conveyor 36. The belt conveyor 36 operates to transport the sandblasting shot into the inner shell 32. The motor 33 on the right rear side of the outer shell 32 starts and drives the spiral shaft 34 to rotate. Through the cooperation of the motor 33 and the spiral shaft 34, the sandblasting shot is pushed to the elevator 35. The elevator 35 lifts the sandblasting shot to the separator 392. Through the cooperation of the elevator 35 and the separator 392, vertical transportation is achieved. After the separator 392 separates impurities, the qualified sandblasting shot is transported to the shot blasting tank 391, realizing the recycling of sandblasting shot.

[0051] Meanwhile, the dust removal mechanism 4 continues to work, and the fan 41 generates negative pressure. Through the cooperation of the fan 41 and the ventilation pipe 44, the dust-laden air in the sandblasting chamber 1 is drawn in and transported to the dust collector 43 through the air duct 42. Through the cooperation of the air duct 42 and the dust collector 43, the dust is filtered, clean air is discharged, and impurities are collected and treated. Finally, after the sandblasting operation is completed, the mechanism is stopped by the button 382, ​​the lifting door 52 is opened and the workpiece is taken out, and the sandblasting process is completed.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
