Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to an automatic shot blasting machine. Background Technology

[0002] Automatic shot blasting machines are surface treatment equipment widely used in many industries such as machinery manufacturing, automobiles, ships, and bridges. They mainly use a high-speed rotating shot blaster to shoot shot particles (such as steel shot, cast shot, etc.) onto the surface of the workpiece to remove oxide scale, rust, oil stains and other adhering substances. At the same time, they increase the surface roughness of the workpiece and improve the adhesion and corrosion resistance of the coating. It is an important step in the pretreatment and strengthening process of workpieces.

[0003] In the casting processing industry, automatic shot blasting machines are core components, and their shot blasting effect and cleaning efficiency have a decisive impact on the overall quality of castings and subsequent processing. Especially in the core process of casting surface cleaning, although existing automatic shot blasting machines can achieve automation and improve production efficiency to a certain extent, a series of obvious limitations and technical problems have gradually been exposed in actual use.

[0004] Specifically, existing automatic shot blasting machines, such as the automatic cleaning shot blasting machine disclosed in utility model patent CN221871669U, although improving shot blasting quality and cleaning efficiency by using rotating cleaning brushes to remove burrs from the outer wall of castings, generate a large amount of dust during use. This dust not only accumulates inside the shot blasting machine, affecting its normal operation and shot blasting effect, but may also drift into the working environment, posing a threat to the health of operators and affecting the processing quality and efficiency of workpieces. Existing shot blasting machines often lack effective dust collection and treatment, making it difficult to solve the dust problem in a timely manner, seriously affecting the processing environment and quality of workpieces. Therefore, in view of the many shortcomings of existing technologies, we urgently need an innovative automatic shot blasting machine to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic shot blasting machine that solves the problem that existing shot blasting machines often lack effective dust collection and treatment, making it difficult to solve dust problems in a timely manner and seriously affecting the processing environment and processing quality of workpieces.

[0006] To achieve the above objectives, this utility model provides an automatic shot blasting machine, including a shot blasting machine,

[0007] It also includes a gas collection hood fixedly connected to both sides of the inner side of the shot blasting machine, an adsorption box fixedly connected to one side of the shot blasting machine, and a spray box fixedly connected to the other side of the shot blasting machine.

[0008] An adsorption plate is fixedly connected to the inner side of the adsorption box, and a spray plate is fixedly connected to the upper inner side of the spray box. A filter plate is fixedly connected to the lower inner side of the spray box. A pump body is fixedly connected to one side of the outer wall of the spray box by bolts. The inlet of the pump body is connected to the lower part of the spray box, and the outlet of the pump body is connected to the top of the spray plate. A fan is fixedly connected to one side of the spray box by bolts. The inlet of the fan is connected to one side of the spray box, and the other side of the spray box is connected to the top of the adsorption box. One side of each of the two gas collection hoods is connected to the bottom of the adsorption box. A discharge valve is installed at the bottom of the shot blasting machine.

[0009] The top of the adsorption box is connected to a connecting pipe, and one end of the connecting pipe is connected to one side of the spray box. A connecting pipe is provided on one side of the shot blasting machine, and both ends of the connecting pipe pass through the side wall of the shot blasting machine and are connected to one side of the two gas collection hoods respectively. One end of the connecting pipe is connected to the bottom of the adsorption box.

[0010] The pump body has a conveying pipe at its inlet, one end of which is connected to the lower part of the spray box. The pump body also has a spray pipe at its outlet, one end of which passes through the top of the spray box and connects to the top of the air collection hood.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figure 1-5 An automatic shot blasting machine includes a shot blasting machine 1, and two gas collecting hoods 16 fixedly connected to the inner sides of the shot blasting machine 1. An adsorption box 8 is fixedly connected to one side of the shot blasting machine 1, and a spray box 3 is fixedly connected to the other side of the shot blasting machine 1. An adsorption plate 15 is fixedly connected to the inner side of the adsorption box 8, and a spray plate 13 is fixedly connected to the upper inner side of the spray box 3. A filter plate 14 is fixedly connected to the lower inner side of the spray box 3. A pump body 11 is fixedly connected to one side of the outer wall of the spray box 3 by bolts. The inlet of the pump body 11 is connected to the lower part of the spray box 3, and the outlet of the pump body 11 is connected to the top of the spray plate 13. A fan 19 is fixedly connected to one side of the spray box 3 by bolts. The inlet of the fan 19 is connected to one side of the spray box 3, and the other side of the spray box 3 is connected to the top of the adsorption box 8. One side of each of the two gas collecting hoods 16 is connected to the bottom of the adsorption box 8. A discharge valve 18 is installed at the bottom of the shot blasting machine 1.

[0024] In the casting processing industry, the automatic shot blasting machine is a core piece of equipment, and its workflow is crucial. First, the workpiece to be shot blasted is placed inside the automatic shot blasting machine 1 for cleaning. During shot blasting, the high-speed rotating shot blaster propels shot particles onto the workpiece surface, effectively removing oxide scale, rust, oil, and other contaminants, while simultaneously increasing the surface roughness to provide a good adhesion base for subsequent coating treatments. However, shot blasting generates a large amount of dust. If this dust is not treated promptly, it will threaten the normal operation of the equipment, the processing quality of the workpiece, and the health of the operators. While the shot blasting machine 1 is operating normally, the blower 19 is started. The blower 19 draws the dust generated during shot blasting into the adsorption box 8 through two air collection hoods 16. The adsorption plates 15, fixedly connected to the inside of the adsorption box 8, filter and adsorb the dust, effectively intercepting it and preventing it from drifting into the working environment. Next, to further improve the dust treatment effect, the dust filtered by the adsorption plates 15 is introduced into the spray box 3. A certain amount of water is injected into the spray box 3 beforehand. The pump 11 is then started, spraying water from the spray plate 13 at the bottom of the spray box 3, forming a water mist to spray and suppress dust. During the spraying process, the dust comes into full contact with the water mist, becoming wet and settling, effectively reducing dust dispersion. Simultaneously, the filter plate 14, fixedly connected to the lower inner side of the spray box 3, filters the used water, removing impurities and dust, thus achieving water recycling. This not only saves water resources but also reduces wastewater discharge, meeting environmental protection requirements. Finally, the treated clean air is discharged through the connection between the other side of the spray box 3 and the top of the adsorption box 8, ensuring a clean working environment and protecting the health of operators. After shot blasting is completed, the cleaned workpiece is unloaded through the discharge valve 18 installed at the bottom of the shot blasting machine 1, completing the entire shot blasting process.

[0025] Furthermore, the top of the adsorption box 8 is connected to a connecting pipe 6, and one end of the connecting pipe 6 is connected to one side of the spray box 3. A connecting pipe 10 is provided on one side of the shot blasting machine 1, and both ends of the connecting pipe 10 penetrate the side wall of the shot blasting machine 1 and are connected to one side of the two gas collection hoods 16 respectively. One end of the connecting pipe 10 is connected to the bottom of the adsorption box 8. During the dust treatment process, the air filtered by the adsorption box 8 can directly enter the spray box 3 through the connecting pipe 6 for further spray dust reduction treatment, or serve as a channel before the clean air is discharged. This enhances the connectivity between the adsorption box 8 and the spray box 3, making the dust treatment process smoother and improving the overall dust treatment efficiency.

[0026] Furthermore, the pump body 11 has a conveying pipe 12 connected to its inlet, and one end of the conveying pipe 12 is connected to the lower part of the spray box 3. The pump body 11 has a spray pipe 7 connected to its outlet, and one end of the spray pipe 7 passes through the top of the spray box 3 and is connected to the top of the gas collection hood 16. During the shot blasting process, the dust generated is first captured by the two gas collection hoods 16, and then directly transported to the adsorption box 8 for filtration and adsorption through the connecting pipe 10. This optimizes the dust collection path, reduces the residence time of dust inside the shot blasting machine, reduces the impact of dust on the equipment and working environment, and improves the dust collection efficiency. The pump body 11 draws water from the lower part of the spray box 3 through the conveying pipe 12, and then transports the water to the spray plate 13 inside the spray box 3 through the spray pipe 7 to form water mist for spraying and dust suppression.

[0027] Furthermore, a top valve 5 is connected to the upper side of the spray box 3, and a bottom valve 4 is connected to the lower side of the spray box 3. When the spray box 3 needs to be filled with water or drained, clean water can be added through the top valve 5 and the used water can be discharged through the bottom valve 4, which facilitates the water management and maintenance of the spray box 3 and improves the operability and ease of use of the equipment.

[0028] Furthermore, a cover plate 9 is rotatably connected to one side of the adsorption box 8 via a hinge, and a door 2 is rotatably connected to one side of the shot blasting machine 1 via a hinge. When it is necessary to inspect, maintain or clean the inside of the adsorption box 8 or the shot blasting machine 1, the cover plate 9 or the door 2 can be opened for operation.

[0029] Furthermore, each of the two gas collecting hoods 16 is provided with an arc-shaped protective net 17 on one side, and one side of each arc-shaped protective net 17 is fixedly connected to the inner wall of the shot blasting machine 1. During the shot blasting process, the arc-shaped protective net 17 can block the shot particles from directly impacting the gas collecting hood 16, protecting the gas collecting hood 16 from damage, enhancing the durability and reliability of the gas collecting hood 16, and reducing the damage and maintenance costs caused by the impact of shot particles.

[0030] In summary:

[0031] The workpiece to be shot-blasted is placed inside the shot blasting machine 1 for cleaning. The high-speed rotating shot blaster propels shot particles onto the workpiece surface, effectively removing oxide scale, rust, oil, and other deposits, while also increasing the surface roughness. During the shot blasting process, the generated dust is first captured by two gas collection hoods 16. The arc-shaped protective net 17 prevents shot particles from directly impacting the gas collection hoods 16, protecting them from damage. The captured dust is then directly transported to the adsorption box 8 through the connecting pipe 10 for filtration and adsorption. The adsorption plate 15 effectively intercepts the dust, preventing it from drifting into the working environment. Simultaneously, the fan 19 is activated, drawing the dust generated during the shot blasting process into the adsorption box 8 through the two gas collection hoods 16, further enhancing the dust collection effect. The air filtered by the adsorption box 8 can then directly enter the spray box 3 through the connecting pipe 6 for further spray dust suppression, or serve as a channel before clean air is discharged. A certain amount of water is pre-filled into the spray box 3. Pump 11 is started, drawing water from the bottom of spray box 3 through delivery pipe 12. The water is then delivered to spray plate 13 inside spray box 3 through spray pipe 7, forming a water mist to spray and suppress dust. During spraying, the dust comes into full contact with the water mist, becoming wet and settling, effectively reducing dust dispersion. Filter plate 14 on the lower inner side of spray box 3 filters the used water, removing impurities and dust, enabling water recycling. This not only saves water resources but also reduces wastewater discharge, meeting environmental protection requirements. The treated clean air is discharged through the connection between the other side of spray box 3 and the top of adsorption box 8, ensuring a clean working environment and protecting the health of operators. After shot blasting, the cleaned workpiece is unloaded through discharge valve 18 installed at the bottom of shot blasting machine 1, completing the entire shot blasting process. The efficient collection and treatment of dust is achieved through the coordination of dust collection hood 16, connecting pipe 10, adsorption box 8, and fan 19, effectively preventing dust from affecting equipment and the working environment. Through the coordination of the spray box 3, pump body 11, spray plate 13, and filter plate 14, dust suppression by spraying and water recycling are achieved, saving water resources and reducing wastewater discharge. The connecting pipe 6 enhances the connectivity between the adsorption box 8 and the spray box 3, making the dust treatment process smoother and improving overall dust treatment efficiency. The arc-shaped protective net 17 protects the gas collection hood 16 from the impact of shot blasting particles, enhancing its durability and reliability. The top valve 5 and bottom valve 4 facilitate water management and maintenance of the spray box 3, improving the equipment's operability and ease of use.
