The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] like Figure 1-Figure 3 As shown, in some embodiments of the present application, this embodiment provides a two-station suspended shot blasting cleaning machine, including: a cleaning part and a dust removal part.

[0043] Specifically, the cleaning section is used to shot blast the workpiece to be cleaned; the dust removal section is connected to the cleaning section, and the dust removal section is used to absorb the exhaust gas when the workpiece is shot blasted, and the dust removal section is also used to filter the dust in the exhaust gas; wherein the cleaning section is provided with a separation module 140, and the separation module 140 is used to separate the steel shots in the exhaust gas.

[0044] Specifically, the cleaning part includes: a cleaning module 110 having a cleaning space 111 therein; a rotating module rotatably connected to the cleaning module 110, wherein the rotating module is used to drive the workpiece to be cleaned to a preset cleaning position inside the cleaning space 111; at least two groups of shot blasting modules 130 are provided, and the two groups of shot blasting modules 130 are arranged side by side on one side of the cleaning module 110, wherein the shot blasting end of the shot blasting module 130 passes through the outer wall of the cleaning module 110 and is arranged inside the cleaned space 111, and the shot blasting module 130 is used to spray steel shots at the workpiece to be cleaned; a separation module 140 is provided on the top of the cleaning module 110, and the separation module 140 is respectively connected to the cleaning space 111 and the shot blasting module 130, and the separation module 140 is used to absorb steel shots and exhaust gas in the cleaning space 111, and the separation module 140 is also used to separate the steel shots and exhaust gas, and guide the separated steel shots to the shot blasting module 130.

[0045] Specifically, the dust removal part includes: a support frame 210 is arranged on one side of the cleaning module 110; the cyclone pretreatment module 220 is embedded in the bottom of the support frame 210, and the cyclone pretreatment module 220 is connected to the support frame 210; the dust reduction box 230 is arranged on one side of the cleaning module 110, and the dust reduction box 230 is connected to the cleaning module 110; one end of the second connecting pipe 240 is connected to the separation host; one end of the first connecting pipe 250 is connected to the dust reduction box 230, and the other end of the first connecting pipe 250 is connected to the cyclone pretreatment module 220, and the middle part of the first connecting pipe 250 is connected to the middle part of the second connecting pipe 240, so that when the second connecting pipe 240 diverts the exhaust gas, the first connecting pipe 250 is used to divert the waste in the exhaust gas to the dust reduction box 230, and the first connecting pipe 250 is also used to divert the exhaust gas to the cyclone pretreatment module 220.

[0046] As can be seen, the cleaning module 110 features a dedicated cleaning space 111 that can accommodate workpieces of various shapes and sizes, ensuring that different workpieces can be effectively shot blasted. The rotating module uses precise mechanical transmission to move the workpieces to be cleaned to the pre-set cleaning position, ensuring that each workpiece receives uniform and thorough cleaning. This design effectively improves the automation level of the production line, reduces the need for manual operation, and thus reduces labor costs and the risk of human error. The shot blasting module 130 plays a crucial role in the cleaning process. Two sets of shot blasting modules 130, positioned side by side, enable simultaneous cleaning of workpieces, improving work efficiency. During the shot blasting process, steel shot is ejected at high speed onto the workpiece surface. The impact force generated not only effectively removes surface dirt but also fine-tunes the surface roughness, preparing the workpiece for subsequent painting or processing. This efficient cleaning method not only improves workpiece quality but also extends the life of subsequent processing. The design of the separation module 140 is another highlight of the equipment. Connected to the cleaning space 111 and the shot blasting module 130, it effectively absorbs the steel shot and exhaust gas generated during the cleaning process. The separation module 140 uses the principle of physical separation to separate the steel shots from the waste gas, ensuring that the steel shots can flow back to the shot blasting module 130 for reuse. This not only reduces material waste, but also reduces production costs. At the same time, the separated waste gas is sent to the dust removal section for treatment, which reflects the high efficiency of the equipment in resource recycling and environmental protection. In the dust removal section, the combination of the support frame 210, the cyclone pretreatment module 220 and the dust reduction box 230 makes the waste gas treatment process smoother. The cyclone pretreatment module 220 uses the principle of centrifugal force to separate the large particles in the waste gas first, reducing the waste gas load entering the dust reduction box 230. The dust reduction box 230 performs a final filtration on the fine particles to ensure that the emitted gas meets environmental protection standards. This series of treatment measures not only improves the environmental performance of the equipment, but also provides strong support for the sustainable development of the enterprise.

[0047] As you can understand, the core of the cleaning unit consists of three components: a cleaning module 110, a rotation module, and a shot blasting module 130. This multi-module design allows the equipment to accommodate workpieces of varying types and specifications, ensuring optimal cleaning for each workpiece. Within the cleaning module 110 lies a dedicated cleaning space 111, carefully designed in size and shape to accommodate workpieces of various shapes and sizes. This design not only optimizes workpiece arrangement but also improves space utilization. The introduction of the rotation module further enhances operational efficiency. Through a precise mechanical transmission system, it smoothly moves the workpiece to be cleaned to a pre-set position in the cleaning space 111. This automated workpiece positioning reduces manual intervention and operational complexity, while ensuring that each workpiece receives consistent treatment during the cleaning process. During operation, the shot blasting module 130 employs at least two parallel sets of shot blasting modules 130, enabling the simultaneous cleaning of multiple workpieces. The design of the shot blasting module 130 sprays steel shot at high velocity onto the workpiece surface, generating a powerful impact that effectively removes rust, oil, and other surface deposits. This highly efficient shot blasting technology not only significantly improves the surface quality of workpieces, but also changes the surface roughness, enhancing adhesion for subsequent coating or other treatments. This is crucial for improving the quality of the final product. Secondly, the design of the separation module 140 is a major highlight of the entire equipment. It not only helps optimize the workflow but also enables resource recycling. The separation module 140 is located on top of the cleaning module 110. Through its connection to the cleaning space 111 and the shot blasting module 130, it can effectively absorb the steel shots and exhaust gas generated during the cleaning process. Its operating principle is based on fluid dynamics, guiding the airflow to separate the steel shots and exhaust gas, ensuring that the steel shots can flow back to the shot blasting module 130 for reuse. This design significantly reduces steel shot loss, improves economic efficiency, and helps reduce production costs. Then, in the dust removal section, the equipment's support frame 210, cyclone pre-treatment module 220, and dust suppression box 230 combine to make the exhaust gas treatment process more efficient. The support frame 210 provides a stable support structure for the entire dust removal section, ensuring the secure connection of all components. The cyclone pretreatment module 220 uses the principle of centrifugal force to perform preliminary separation of large particles in the exhaust gas, reducing the exhaust gas load entering the dust removal box 230. This process not only reduces the working pressure of the dust removal box 230, but also extends the service life of the equipment. Subsequently, the exhaust gas is introduced into the dust removal box 230 through the first connecting pipe 250 for more detailed filtration and treatment to ensure that the final exhaust gas meets environmental protection standards. Finally, the design of the dust removal box 230 is equally important. Multiple layers of filter screens and adsorption materials are set inside it to effectively capture fine particles in the exhaust gas and reduce environmental pollution. The treated clean gas will be discharged safely, ensuring the safety and hygiene of the equipment operating environment, while also meeting the environmental protection requirements of modern industry.Through this series of processing steps, the equipment not only effectively reduces the burden on the environment, but also lays the foundation for the sustainable development of the enterprise.

[0048] In some embodiments of the present application, the separation module 140 includes: a separation host is arranged at the top of the cleaning module 110, and the separation host is connected to the cleaning space 111; a recovery spiral unit 142 is arranged in the middle and lower part of the cleaning space 111, and the recovery spiral unit 142 is rotatably connected to the inner wall of the cleaning space 111; the recovery spiral unit 142 drives the steel shots to move along the direction selected by the recovery spiral unit 142; an elevator 143 is arranged on one side of the recovery spiral unit 142, and the elevator 143 is connected to the inner wall of the cleaning space 111, and the elevator 143 is used to lift the steel shots driven by the recovery spiral unit 142 to the inside of the separation host; a dust suction unit is arranged inside the separation host, and the dust suction unit is used to attract the exhaust gas inside the cleaning space 111; one end of the guide pipe is connected to the separation host, and the other end of the guide pipe is connected to the shot blasting module 130, and the guide pipe is used to guide the steel shots separated by the separation host to the shot blasting module 130, wherein the guide pipe is also provided with a shot supply valve.

[0049] It is understandable that the separation host is located at the top of the cleaning module 110, is connected to the cleaning space 111, and can receive waste gas and steel shots from the cleaning space 111 in real time. The recovery spiral unit 142 is arranged in the middle and lower part of the cleaning space 111, and is connected to the inner wall by rotation, driving the steel shots to move in a spiral direction and transporting them to the elevator 143. The function of the elevator 143 is to lift the steel shots in the recovery spiral unit 142 to the inside of the separation host to ensure that the steel shots are collected in a centralized manner. At the same time, the dust collection unit is responsible for attracting the waste gas in the cleaning space 111 inside the separation host, and further improves the waste gas treatment efficiency through effective airflow management. The guide pipe connects the separation host and the shot blasting module 130, and is responsible for diverting the separated steel shots back to the shot blasting module 130 to achieve the reuse of the steel shots. The shot supply valve provided in the guide pipe provides precise control for the flow of the steel shots, ensuring that the steel shots can be delivered to the shot blasting module 130 in a timely manner when needed.

[0050] In some embodiments of the present application, the dust removal unit also includes: an operating platform 260 arranged on the top of the support frame 210, and the operating platform 260 is connected to the support frame 210; an escalator 270 is arranged on one side of the operating platform 260, and the escalator 270 is connected to the operating platform 260.

[0051] In some embodiments of the present application, the shot blasting module 130 is further provided with a cylinder and a control unit: the cylinder is connected to the shot blasting module 130, and the cylinder is used to supply airflow to the shot blasting module 130; the control unit is electrically connected to the cylinder, and the control unit is used to adjust the airflow rate of the supplied airflow.

[0052] In some embodiments of the present application, an electrical interlock is further provided between the cleaning module 110 and the shot blasting module 130 .

[0053] It is understood that the air cylinder is connected to the shot blasting module 130 to supply airflow, ensuring that the steel shot is ejected at the appropriate air pressure and flow rate. This design allows the operator to adjust the air flow in real time according to the cleaning requirements of different workpieces, thereby optimizing the shot blasting effect and improving cleaning efficiency. In addition, the electrical interlock mechanism between the cleaning module 110 and the shot blasting module 130 enhances the safety of the equipment, ensuring that when one module is operating, the other is in a safe state, preventing misoperation or equipment damage.

[0054] In some embodiments of the present application, a wear-resistant guard plate is further provided inside the cleaning space 111, and the material of the wear-resistant guard plate is high manganese Mn15Cr1 material.

[0055] It is understandable that the wear-resistant guard plate installed inside the cleaning space 111 is designed to improve the durability and service life of the equipment. The wear-resistant guard plate, made of high-manganese Mn15Cr1 material, has excellent wear resistance and impact resistance, and can effectively resist the wear of the inner wall caused by steel shots during the shot blasting process. This material performs well in high-stress environments, can slow the wear rate of the guard plate, reduce maintenance frequency and replacement costs, and thus improve the economy and reliability of the overall equipment. In addition, the provision of the wear-resistant guard plate also ensures the structural integrity of the cleaning space 111, making the shot blasting cleaning process more efficient and stable, ensuring the cleaning effect and workpiece quality.

[0056] In the above-described embodiment, the cleaning unit specifically targets the workpiece to be cleaned by shot blasting. High-speed rotating steel shots impact the workpiece surface, effectively removing rust, dirt, and other deposits. This cleaning method not only improves the cleanliness of the workpiece surface but also enhances its adhesion for subsequent processing or coating, ensuring the quality of the final product. Secondly, during the cleaning process, the dust removal unit, connected to the cleaning unit, can promptly absorb the exhaust gas generated during workpiece cleaning, minimizing the impact on operators. This ensures a clean working environment, reduces the risk of air pollution, and meets modern environmental protection requirements. Furthermore, good air quality improves worker efficiency and comfort. Finally, the separation module 140 in the cleaning machine effectively separates the steel shots from the exhaust gas. This design not only reduces steel shot waste, allowing for its reuse, improving resource utilization efficiency, but also reduces production costs. Over time, this efficient resource management method saves companies significant material costs and helps improve overall production efficiency.
