Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically an environmentally friendly shot blasting machine. Background Technology

[0002] A shot blasting machine is a mechanical device that uses high-speed shot projectiles to clean or strengthen the surface of workpieces. Shot blasting machines can simultaneously remove sand, cores, and clean castings, and can also be used for surface treatment of forgings, aluminum-magnesium alloy parts, and sheet metal weldments. In some regions, they are also colloquially called sandblasting machines or blasting machines. However, traditional shot blasting machines generate dust during operation, polluting the working environment and harming human health. Furthermore, they are inconvenient to classify steel shot and waste, making them difficult to use.

[0003] In the prior art, utility model patent CN213731232U discloses an environmentally friendly shot blasting machine, including a housing and a filter plate; the filter plate is slidably installed inside the housing; two assembly slots are symmetrically opened on the inner wall of the housing; a fixing rod is fixedly installed inside the assembly slot; a slider is fixedly installed on the filter plate, and the slider is slidably connected to the fixing rod; a spring is fixedly connected to the slider at its top end and to the inner wall of the assembly slot at its bottom end; and a rotating rod is rotatably installed on the housing, with one end of the rotating rod penetrating through the housing.

[0004] Regarding the aforementioned solutions, the dust filtration achieved through the combined use of a suction pipe, housing, water pump, branch pipe, and exhaust fan plays an environmental protection role. However, in this process, the dust sent into the housing through the suction pipe is prone to forming large air bubbles that quickly rise and burst, resulting in less gas-liquid contact time. Consequently, the dust is discharged with the airflow without being properly moistened. Furthermore, the water circulation relies solely on simple spraying by the water pump, which cannot create effective turbulence, thus failing to allow the dust to fully contact and be treated with water. Utility Model Content

[0005] The purpose of this utility model is to provide an environmentally friendly shot blasting machine to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An environmentally friendly shot blasting machine includes a housing with discharge troughs on both sides for discharging steel shot. A filter plate, penetrating the housing, is slidably connected inside the discharge trough to separate the steel shot and debris. A support spring connects the shot blaster to the discharge trough. Shot blasters are symmetrically installed above the filter plate inside the housing. A water tank is located at the rear of the housing. Inside the water tank, from bottom to top, are arranged an air guide plate, a flow guide plate, and a spray plate. The air guide plate extends to the outside of the water tank and communicates with the housing. The flow guide plate has a spiral rotating structure with staggered through holes to prevent air bubbles from merging. A striking mechanism for vibrating the spray plate is located between the spray plate and the housing. The striking mechanism includes an eccentric disc rotatably connected to the inside of the water tank and vertical plates symmetrically welded to the inside of the water tank. A fan is installed at the center of the top of the water tank, and a water pump is installed on a mounting plate on one side of the water tank.

[0007] Preferably, the water tank includes a cylindrical body and a cover installed on the top of the cylindrical body, and the cover and the cylindrical body are detachably connected by bolts. Both sides inside the water tank are fixedly connected to a support plate, and a support frame is provided on the outer side of the guide plate, and the top of the support frame is connected to the cover.

[0008] Preferably, the eccentric disc includes a circular plate and a rotating shaft welded to the top of the circular plate. The end of the rotating shaft away from the circular plate is rotatably connected to the water tank via a bearing. The inner side of the spray disc is provided with a side frame that forms a sliding structure with the upright plate. The side frame includes a side plate and a support rod welded to one side of the side plate. A return spring is connected between the upright plate and the side plate.

[0009] Preferably, a servo motor is installed on one side of the top of the water tank. The servo motor is used to drive the eccentric disk to rotate. A pulley set is connected between the output end of the servo motor and the eccentric disk. The pulley set is used to make the eccentric disk rotate synchronously with the output end of the servo motor.

[0010] Preferably, the fan is used to drive the airflow carrying dust, the outside of the spray plate is connected to a corrugated pipe that passes through the water tank, the water pump is used to provide power for pumping water, both ends of the water pump are connected to water pipes, one end of the water pipe away from the water pump is connected to the corrugated pipe, and the other end of the water pipe away from the water pump is connected to the water tank.

[0011] Preferably, the inner side of the water tank is provided with a filter cover that matches the water pipe, and the filter cover is used to prevent the water pipe from getting clogged.

[0012] Preferably, a slide rail is provided at the top of the housing, a hook is installed at the bottom of the slide rail, and a collection box is provided at the bottom of the housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the vibration of the spray plate by the striking mechanism causes the water flow to oscillate, thereby generating finer water droplets, significantly increasing the gas-liquid contact area. This facilitates the capture of dust particles by the droplets through inertial collision and interception, thus improving the dust removal rate. Furthermore, the water flow oscillation can disrupt the straight upward path of the airflow, prolonging the residence time of dust in the droplets, allowing the tiny particles to form larger agglomerates through Brownian diffusion and coagulation effects, which facilitates sedimentation and separation. In addition, the vibration of the spray plate can prevent the spray holes from clogging, ensuring that the water flow continuously covers the spiral plate area. At the same time, combined with the turbulence generated by the spiral guide plate and through holes, it strengthens the cross-flow contact between gas and liquid, improving the overall dust removal stability.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Please see Figure 1 and Figure 4This utility model provides an environmentally friendly shot blasting machine, including a housing 1. Both sides of the housing 1 are provided with discharge troughs 14 for discharging steel shot. The discharge troughs 14 are slidably connected inside the discharge troughs 14, penetrating the housing 1. The filter plates 3 are used to separate steel shot and debris. A support spring 4 is connected between the shot blaster 2 and the discharge troughs 14. The shot blasters 2 are symmetrically installed inside the housing 1 above the filter plates 3. A slide rail is provided at the top of the housing 1, and a hook is installed at the bottom of the slide rail. A collection box 15 is provided at the bottom of the housing 1.

[0018] Specifically, the workpiece to be processed is placed on the hook and moved into the housing 1 by the slide rail. After the door is closed, the surface of the workpiece is cleaned by the shot blaster 2. During this process, the steel shot and debris move downwards. The steel shot and debris are separated by the cooperation of the filter plate 3 and the support spring 4. The steel shot is discharged through the discharge chute 14 and the debris is collected through the collection box 15.

[0019] See Figures 1-4 A water tank 5 is located at the rear of the housing 1. Inside the water tank 5, from bottom to top, are arranged a guide plate 7, a baffle plate 12, and a spray plate 9. The guide plate 7 extends to one end of the water tank 5 and communicates with the housing 1. The baffle plate 12 is a spiral structure with staggered through holes 13 inside. The through holes 13 are used to increase the probability of inertial collision between droplets and dust while preventing bubble coalescence. Specifically, the airflow carrying dust is evenly sprayed into the water tank 5 through the guide plate 7. The spiral baffle plate 12 forces the airflow to rise along a spiral trajectory to prolong the gas-liquid contact time. Simultaneously, the airflow friction against the plate wall generates vortices, tearing apart bubbles. The airflow is then diverted through the through holes 13 to prevent localized high pressure from causing bubble coalescence, while simultaneously increasing the probability of inertial collision between droplets and dust.

[0020] See Figure 1 , Figure 2 and Figure 4 In this system, the water tank 5 includes a cylindrical body and a cover mounted on the top of the cylindrical body. The cover and the cylindrical body are detachably connected by bolts. Support plates are fixedly connected to both sides inside the water tank 5. A support frame is provided on the outer side of the guide plate 12, and the top of the support frame is connected to the cover. Specifically, after the bolts are separated from the cylindrical body, the support frame can be moved away from the support plates by rotating the cover at a certain angle. At this point, the guide plate 12 can be removed by moving the cover upwards for rinsing.

[0021] See Figures 1-4In the middle, a striking mechanism 8 for vibrating the spray plate 9 is provided between the spray plate 9 and the housing 1. The striking mechanism 8 includes an eccentric plate 803 rotatably connected to the inside of the water tank 5 and a vertical plate 804 symmetrically welded to the inside of the water tank 5. The eccentric plate 803 includes a circular plate and a rotating shaft welded to the top of the circular plate. The end of the rotating shaft away from the circular plate is rotatably connected to the water tank 5 through a bearing. A side frame is provided on the inside of the spray plate 9, which forms a sliding structure with the vertical plate 804. The side frame includes a side plate and a support rod welded to one side of the side plate. A return spring 805 is connected between the vertical plate 804 and the side plate. A servo motor 801 is installed on one side of the top of the water tank 5. The servo motor 801 is used to drive the eccentric plate 803 to rotate. A pulley group 802 is connected between the output end of the servo motor 801 and the eccentric plate 803. The pulley group 802 is used to make the eccentric plate 803 rotate synchronously with the output end of the servo motor 801.

[0022] Specifically, when the servo motor 801 is working, the output end of the servo motor 801 drives the eccentric disk 803 to rotate under the action of the pulley group 802. Since the spray disk 9 and the vertical plate 804 are elastically connected by the return spring 805, during the process of the eccentric disk 803 away from the rotating shaft contacting and separating from the spray disk 9, the spray disk 9 can vibrate through the cooperation of the eccentric disk 803 and the return spring 805, thereby causing the water flow to oscillate, so as to generate finer water droplets, significantly increasing the gas-liquid contact area, which is conducive to dust particles being captured by the droplets through inertial collision and interception, so as to improve the dust removal rate. Moreover, the water flow oscillation can disrupt the straight upward path of the airflow, prolong the residence time of dust in the droplets, and allow the tiny particles to form larger agglomerates through Brownian diffusion and coagulation effects, which is convenient for sedimentation and separation. In addition, the vibration of the spray disk 9 can avoid the clogging of the spray holes and ensure that the water flow continuously covers the spiral plate area.

[0023] See Figures 1-3 A fan 6 is installed at the top center of the water tank 5. The fan 6 is used to drive the airflow carrying dust. A corrugated pipe 16 that runs through the water tank 5 is connected to the outside of the spray plate 9. A water pump 11 is installed on the mounting plate on one side of the water tank 5. The water pump 11 is used to provide power for pumping water. Both ends of the water pump 11 are connected to water pipes 10. One end of the water pipe 10 away from the water pump 11 is connected to the corrugated pipe 16, and the other end of the water pipe 10 away from the water pump 11 is connected to the water tank 5.

[0024] Specifically, when the water pump 11 is working, the water pump 11 draws water from the water tank 5 through the water pipe 10, and sends the water into the spray plate 9 through the water pipe 10 and the corrugated pipe 16, so as to intercept dust through the water flow.

[0025] exist Figure 2 In the middle: A filter cover matching the water pipe 10 is installed inside the water tank 5. The filter cover is used to prevent the water pipe 10 from becoming clogged. Impurities are filtered through the filter cover to prevent them from clogging the water pipe 10.

[0026] The working principle of this utility model is as follows: The workpiece to be processed is placed on the hook and moved into the housing 1 by the slide rail. After the door is closed, the surface of the workpiece is cleaned by the shot blaster 2. During this process, steel shot and debris move downwards. The steel shot and debris are separated by the cooperation of the filter plate 3 and the support spring 4. The steel shot is discharged through the discharge chute 14 and the debris is collected through the collection box 15. At the same time, the blower 6, water pump 11 and servo motor 801 are started, so that the blower 6 disperses the airflow containing dust in the housing 1 into the water tank 5 through the air guide plate 7. Then, the airflow is forced to rise along the spiral trajectory by the spiral guide plate 12 to prolong the gas-liquid contact time. At the same time, the airflow generates vortices by friction with the plate wall, tearing the bubbles. The airflow is diverted through the through hole 13 to avoid local high pressure. This causes bubbles to merge and increases the probability of inertial collisions between droplets and dust. When the water pump 11 is working, the water pump 11 draws water from the water tank 5 through the water pipe 10 and sends the water into the spray plate 9 through the water pipe 10 and the corrugated pipe 16 so that the dust can be intercepted by the water flow. When the servo motor 801 is working, the output end of the servo motor 801 drives the eccentric disk 803 to rotate under the action of the pulley group 802. Through the elastic action of the spray plate 9 and the vertical plate 804, during the process of contact and separation between the end of the eccentric disk 803 away from the rotating shaft and the spray plate 9, the spray plate 9 can be vibrated by the cooperation of the eccentric disk 803 and the return spring 805, which in turn causes the water flow to oscillate, so as to significantly increase the gas-liquid contact area and facilitate the capture of dust particles by droplets through inertial collision and interception. Electrical equipment (including but not limited to motors, electric actuators, etc.) is safely powered by an external power source and controlled through a control box.
