Description

Technical Field

[0001] This utility model relates to the field of safety protection device technology, specifically a safety protection device for an aluminum cutting machine. Background Technology

[0002] Aluminum cutting machines are specialized mechanical equipment used for the efficient cutting of aluminum profiles. They are widely used in the construction, industrial, and furniture manufacturing industries. Their core function is to quickly and accurately cut aluminum materials to set dimensions using high-precision blades and an automated control system, ensuring a smooth and flat cut surface to meet various process requirements. However, while aluminum cutting machines operate efficiently, they also pose potential risks such as mechanical injury and flying debris. Therefore, safety protection devices are an indispensable component. Multiple protective measures, such as protective covers, emergency braking systems, and light curtain sensors, can effectively isolate dangerous areas, prevent operators from accidentally touching the blades, and monitor abnormal situations in real time and respond quickly, ensuring that the equipment operates with both high efficiency and safety.

[0003] Safety protection devices for aluminum cutting machines can effectively protect workers and create a good working environment, but they still have certain problems: 1) Existing safety protection devices are mostly for physical protection, and fine aluminum dust can adhere to them. During operation, the dust is difficult to clean and can easily be inhaled into the lungs, posing certain safety hazards; 2) The aluminum cutting process generates harmful waste gas, which can pollute the environment if directly emitted and can also cause harm to the human body if inhaled by workers. Therefore, in view of the above situation, it is urgent to develop a safety protection device for aluminum cutting machines to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this utility model is to provide a safety protection device for an aluminum cutting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety protection device for an aluminum cutting machine, comprising a cyclone separator and a workbench, the workbench being located on one side of the cyclone separator, and separation cabinets a, b, and c being installed sequentially on the workbench, with separation cabinets a, b, and c being connected in series via pipes; a centrifugal fan is installed at the outlet of the cyclone separator, and an exhaust pipe for connection is installed between the outlet of the centrifugal fan and the inlet of separation cabinet a;

[0006] The cyclone separator has an internal air duct that connects to the outlet, and the outer wall of the air duct is fitted with a spiral air guide plate.

[0007] Inside the separation cabinet a, an electrostatic precipitator and filter screen a are installed sequentially.

[0008] The interior of the separation cabinet b is equipped with filter screen b;

[0009] The interior of the separation cabinet C is equipped with an exhaust gas treatment component.

[0010] Preferably, a collection tank is installed at the bottom of the cyclone separator. Specifically, the collection tank is used to collect large particulate impurities separated by the cyclone separator, thereby reducing the pressure on the subsequent filter screen and improving the filtration effect.

[0011] Preferably, filter a has a lower mesh size than filter b. Specifically, the exhaust gas is pre-filtered by filter a with a lower mesh size, and then the exhaust gas is filtered by filter b with a higher mesh size, which ensures the filtration effect while reducing the filter pressure.

[0012] Preferably, the exhaust gas treatment component includes a treatment tank, a circulating pump, a deluge plate, a dispersion tank, and a conduit. The treatment tank is installed inside the separation cabinet c. Several deluge plates are installed vertically and equidistantly on the treatment tank. The dispersion tank is fitted onto the deluge plates. The circulating pump is installed inside the treatment tank. The two ends of the conduit are connected to the outlet of the circulating pump and the dispersion tank, respectively. Specifically, the exhaust gas treatment component circulates the reagent in the treatment tank. In conjunction with the deluge plates, the reagent comes into full contact with the aluminum cutting exhaust gas and undergoes a chemical reaction, thereby achieving the exhaust gas treatment effect.

[0013] Preferably, a chemical neutralizing agent for treating the waste gas generated during aluminum cutting is injected into the treatment tank. Specifically, the chemical neutralizing agent is a sodium hydroxide solution.

[0014] Compared with the prior art, this utility model provides a safety protection device for an aluminum cutting machine, which has the following beneficial effects:

[0015] This design achieves synergistic and efficient treatment of aluminum dust and harmful exhaust gases through a cyclone separator combined with a multi-stage filtration system: the cyclone separator uses spiral guide plates to enhance centrifugal force, initially separating large dust particles and suppressing their flight; the three-stage separation cabinets connected in series sequentially pass through electrostatic adsorption, gradient filter interception, and rain-induced chemical neutralization, which can capture dust of different particle sizes (including ultrafine particles) in stages, significantly reducing the risk of inhalation into the lungs of operators, and can also react with the agents in the circulating pool to convert harmful components in the exhaust gas into harmless substances, significantly reducing environmental pollution. The entire device has the advantages of high dynamic dust collection rate, thorough exhaust gas purification, and low operating cost, constructing a full-process safety protection system from source control to end-of-pipe treatment.

[0023] Example:

[0024] Please see Figures 1-3This utility model provides a technical solution: a safety protection device for an aluminum cutting machine, including a cyclone separator 10 and a workbench 50. The workbench 50 is located on one side of the cyclone separator 10. Separation cabinets a20, b30 and c40 are installed on the workbench 50 in sequence, and separation cabinets a20, b30 and c40 are connected in series through pipes. A centrifugal fan 120 is installed at the outlet of the cyclone separator 10, and an exhaust pipe 130 is installed between the outlet of the centrifugal fan 120 and the inlet of the separation cabinet a20 for connection.

[0025] The cyclone separator 10 has an internal air guide pipe 140 that communicates with the outlet, and the outer wall of the air guide pipe 140 is fitted with a spiral air guide plate 150.

[0026] Inside the separation cabinet a20, an electrostatic precipitator 210 and a filter screen a220 are installed sequentially.

[0027] The internal filter of the separation cabinet b30 is equipped with filter screen b310;

[0028] The interior of the separation cabinet c40 is equipped with an exhaust gas treatment component 410.

[0029] Preferably, a collection tank 110 is installed at the bottom of the cyclone separator 10. Specifically, the collection tank 110 is used to collect large particulate impurities separated by the cyclone separator 10, thereby reducing the pressure on the subsequent filter screen and improving the filtration effect.

[0030] Preferably, filter a220 has a lower mesh size than filter b310. Specifically, the exhaust gas is pre-filtered by filter a220 with a lower mesh size, and then the exhaust gas is filtered by filter b310 with a higher mesh size, which ensures the filtration effect while reducing the filter pressure.

[0031] Preferably, the exhaust gas treatment component 410 includes a treatment tank 411, a circulation pump 412, a rain shower plate 413, a dispersion tank 414, and a conduit 415. The treatment tank 411 is installed inside the separation cabinet c40. Several rain shower plates 413 are installed vertically and equidistantly on the treatment tank 411. The dispersion tank 414 is fitted onto the rain shower plates 413. The circulation pump 412 is installed inside the treatment tank 411. The two ends of the conduit 415 are respectively connected to the outlet of the circulation pump 412 and the dispersion tank 414. Specifically, the exhaust gas treatment component 410 circulates the reagent in the treatment tank 411. With the help of the rain shower plate 413, the reagent comes into full contact with the aluminum cutting exhaust gas and undergoes a chemical reaction, thereby achieving the exhaust gas treatment effect. Several uniformly distributed through holes are opened on the lower surface of the dispersion tank 414.

[0032] Preferably, a chemical neutralizing agent for treating the waste gas generated during aluminum cutting is injected into the treatment tank 411. Specifically, the chemical neutralizing agent is a sodium hydroxide solution.

[0033] Working principle: The air inlet of the cyclone separator 10 is connected to the interior of the aluminum cutting machine. During operation, the centrifugal fan 120 is started, and the air and aluminum powder inside the aluminum cutting machine are drawn into the cyclone separator 10. After centrifugal separation, large particles are separated and fall into the collection tank 110 below, while the air is introduced into the separation cabinet a20 through the exhaust pipe 130, and then flows sequentially through the separation cabinets b30 and c40 before being discharged. When it flows through the separation cabinet a20, the electrostatic precipitator 21... 0 generates static electricity and adsorbs fine dust. Filter a220 removes larger particles. When it flows through the diversion cabinet b30, smaller dust particles are removed by the denser filter b310. When it flows through the separation cabinet c40, the circulating pump 412 guides the sodium hydroxide solution in the treatment tank 411 to the dispersion tank 414. Then, the uniformly distributed through holes at the bottom of the dispersion tank 414 evenly disperse the solution onto the rain shower plate 413. When the waste gas flows through the rain shower plate 413, it comes into full contact with and is neutralized by the sodium hydroxide solution, thus achieving waste gas treatment.
