Description

Technical Field

[0001] The utility model relates to the technical field of plasma cutting, in particular to a smoke and dust processing device. Background Art

[0002] Plasma cutting is a processing method that uses plasma technology to cut materials. The principle of plasma cutting is to use the high energy of plasma to heat and melt the material, generate high-speed ions and electron beams during the cutting process, and peel or cut the material. Plasma cutting can achieve high-speed and high-precision cutting, and is suitable for cutting needs of various shapes and materials. A smoke treatment device is required when performing plasma cutting.

[0003] After the existing smoke treatment equipment completes the smoke treatment, the smoke accumulated on the inner wall of the cyclone chamber will gradually accumulate and adhere, reducing the separation efficiency of the cyclone chamber. Since the cyclone chamber usually has a complex internal structure and curved surface, simple cleaning cannot effectively remove the smoke completely, so that part of the smoke cannot be effectively separated and removed, affecting the treatment effect of the smoke treatment equipment. When performing smoke treatment, since the fine dust is composed of small particles floating in the air, it is difficult to be captured and filtered by the smoke treatment equipment. After the smoke is treated, a large amount of fine dust will still remain in the air, which cannot be effectively adsorbed. Summary of the invention

[0004] The purpose of the utility model is to solve the problem that after the smoke treatment is completed, the smoke accumulated on the inner wall of the cyclone chamber of the existing smoke treatment equipment in the prior art will gradually accumulate and adhere, thereby reducing the separation efficiency of the cyclone chamber. Since the cyclone chamber usually has a complex internal structure and curved surface, simple cleaning cannot effectively remove the smoke completely, so that part of the smoke cannot be effectively separated and removed, affecting the treatment effect of the smoke treatment equipment. When the smoke treatment work is carried out, since the fine dust is composed of small particles and floats in the air, it is difficult to be captured and filtered by the smoke treatment equipment.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A smoke and dust treatment device comprises a cyclone chamber 2, a support frame 1 is installed on the outer wall of the cyclone chamber 2, a collecting box 3 is connected to the bottom end of the cyclone chamber 2, a dust collecting drawer 4 is slidably provided on the inner wall of the collecting box 3, an air outlet pipe 5 is connected to one side of the outer wall of the cyclone chamber 2, a filter 10 is installed in the air outlet pipe 5, and a cover plate 6 is provided on the top of the cyclone chamber 2;

[0022] It also includes an electrostatic adsorption plate 7, a spray pipe 11 and a nozzle 12. The electrostatic adsorption plate 7 is installed at the bottom of the cover plate 6, and the spray pipe 11 is installed at the bottom of the electrostatic adsorption plate 7. The spray pipe 11 is connected to the nozzle 12.

[0023] An air inlet hole is opened at the center axis of the top of the cover plate 6, and a central duct 13 is connected to the air inlet hole. The top of the central duct 13 is connected to the air inlet pipe 8, and a fan 9 is installed on the air inlet pipe 8. When the fan 9 is started, negative pressure is generated. Under the action of the negative pressure, the processed smoke enters the central duct 13 from the air inlet pipe 8.

[0024] The electrostatic adsorption plate 7 is disc-shaped, and the shape and size of the electrostatic adsorption plate 7 match the shape and size of the opening on the top surface of the inner wall of the cyclone chamber 2. The electrostatic adsorption plate 7 is fitted on the bottom surface of the cover plate 6. The electrostatic adsorption plate 7 is a device that uses electrostatic force to adsorb and capture particulate matter. It is composed of a plate-like structure made of conductive material, and the surface carries static charge, which can adsorb and capture passing particles. When the particles pass through the electrostatic adsorption plate 7, due to the effect of the static charge, the particles will be quickly adsorbed on the plate, thereby realizing the separation and collection of the particles.

[0025] Mounting holes are respectively provided at corresponding positions of the cover plate 6 and the electrostatic adsorption plate 7. The top branch pipe of the spray pipe 11 passes through the mounting hole and is installed at the bottom of the electrostatic adsorption plate 7. The spray pipe 11 is in a circular ring shape and is provided with water spray holes corresponding to the nozzles 12. The nozzles 12 are provided in a circle on the spray pipe 11. Cleaning liquid is sprayed out from the water spray holes to cover the entire bottom of the electrostatic adsorption plate 7 and wash away the dirt and pollutants accumulated on the inner wall of the cyclone chamber 2.

[0026] An air outlet hole is opened on one side of the outer wall of the cyclone chamber 2, and the air outlet pipe 5 is connected and arranged on the air outlet hole. The shape and size of the filter 10 match the shape and size of the inner wall of the air outlet pipe 5.

[0027] The central duct 13 is in the shape of a cylinder with openings at the top and bottom. A dust collecting hole is opened on the top of the collecting box 3. The bottom end of the cyclone chamber 2 is connected to the collecting box 3 through the dust collecting hole. The dust collecting drawer 4 is installed in the collecting box 3 through a slide rail. The exhaust gas enters the cyclone chamber 2 and forms a vortex with the gas in the central duct 13 to generate a high-speed cyclone. Since the gas in the vortex rotates at a high speed and there is centrifugal force, the particulate matter is thrown out of the airflow under the action of the centrifugal force and deposited on the wall of the cyclone 2.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using the present device, firstly, the electrical equipment in the present device is connected to an external power source, and the device is placed in a designated working position. Through the cooperation of the electrostatic adsorption plate 7, the spray pipe 11 and the nozzle 12, the detergent can be sprayed through the spray pipe 11 and the nozzle 12 to effectively remove dust and dirt, keep the inner wall of the cyclone chamber clean, restore and improve the separation performance of the equipment, ensure the smoke treatment effect, prevent blockage, ensure smooth ventilation of the equipment, reduce the loss and wear of the equipment, and help to extend the service life of the equipment. Fine dust will be adsorbed to the surface of the electrostatic adsorption plate 7 under the action of electrostatic force, so as to achieve complete removal of fine dust, improve the treatment efficiency of the smoke treatment equipment, and avoid fine dust being released into the atmosphere again after the equipment has treated the smoke, thereby reducing the risk of secondary pollution.
