Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly cyclone water curtain cabinets, specifically an environmentally friendly cyclone water curtain cabinet. Background Technology

[0002] Water curtain booths are mainly used for treating paint spraying exhaust gases. The air in the paint spraying workshop contains paint powder. Through negative pressure equipment, the air containing paint powder is introduced into the cyclone water curtain booth. The cyclone water curtain booth can knock the paint powder in the air into the water tank, filtering out some of the paint powder in the air. Then, the air enters the cyclone water curtain booth and is thoroughly mixed with water by the internal cyclone flow. This causes the dust in the air to flow into the water tank with the water, protecting the working environment and improving the environmental performance of the painting process.

[0003] Existing environmentally friendly cyclone water curtain cabinets, such as the one proposed in patent application number "CN202020032136.1" for waste gas treatment, include a cabinet body, cavity cover, exhaust pipe, filter screen, water tank, and filter box. By using the suction of a fan to draw waste gas from the production process into the cabinet body, the waste gas is decelerated by the water curtain and enters the rear side of the first partition. The rotating shaft is rotated by the wind-blown agitator, thereby causing the waste gas dust and water mist to collide and merge at high speed and be adsorbed. The dust is finally returned to the circulating water tank, which improves the waste gas treatment effect.

[0004] However, existing technologies have drawbacks. Particles such as paint powder in the air enter the water tank with the water flow, causing significant water flow noise. Furthermore, it is difficult to clean the paint powder and other particles once they enter the water tank. Therefore, an environmentally friendly cyclone water curtain cabinet is proposed.

[0023] 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 scope of protection of the present utility model.

[0024] An environmentally friendly cyclone water curtain cabinet, such as Figures 1-4 As shown, the device includes a cabinet 1, inside which a vortex emulsification chamber 4 is fixedly connected. An air inlet 3 is provided below the vortex emulsification chamber 4. A water curtain is fixedly connected to the top of the inner wall of the cabinet 1, and a water tank 8 is fixedly connected to the bottom of the cabinet 1. The air inlet 3 is located between the water curtain and the water tank 8. A buffer component and a cleaning component are provided in the water tank 8. The buffer component is located between the air inlet 3 and the cleaning component. A cyclone barrel 5 is fixedly connected to the upper end of the vortex emulsification chamber 4. The interior of the cyclone barrel 5 is connected to the interior of the vortex emulsification chamber 4. An air outlet 6 is fixedly connected to the upper end of the cabinet 1. The upper end of the cyclone barrel 5 is connected to the air outlet 6. An air outlet 7 is provided on the air outlet 6.

[0025] Air carrying particles such as paint powder enters the cabinet 1, first contacting the water curtain, then entering the air inlet 3. The water curtain knocks some of the air particles into the water tank 8. The air then enters the vortex emulsification chamber 4, and then the cyclone barrel 5. The swirling inside both chambers mixes the air with the water flow, and impurities in the air are carried back into the water tank 8 with the water flow. After treatment, the air is discharged through the air outlet 7 of the air outlet 6. The buffer component reduces the impact of the water flow entering the water tank 8, reduces water flow noise, and prevents water splashing. The cleaning component facilitates the removal of particulate impurities collected in the water tank 8, reducing the difficulty of cleaning the water tank 8. This environmentally friendly cyclone water curtain cabinet is suitable for the treatment of continuous and intermittent exhaust gas emissions. Its process is simple, and it is convenient to manage, operate, and maintain. It will not affect the production in the workshop and has a wide range of applications. It can purify multiple pollutants at the same time and has a very good dust removal effect.

[0026] The work includes the following steps:

[0027] Exhaust gas entry: Dust or exhaust gas generated in the production workshop, under the traction of the negative pressure fan, and emulsified exhaust gas particles generated by spraying paint or adhesive, enter the cabinet 1 with the flowing air, pass through the water curtain (the water in the water curtain is drawn from the water tank 8 by the water pump to the outlet of the water curtain), and the exhaust gas particles are blown into the water tank 8 by the water curtain. Most of the waste material still enters the air inlet 3 with the air and enters the vortex emulsification chamber 4.

[0028] Waste gas mixing and emulsification: After the waste gas cyclone emulsification chamber 4, the paint powder particles, cyclone (the cyclone emulsification chamber 4 is equipped with a rotating device for generating cyclone) and water undergo gas-liquid emulsification reaction in high-speed rotation. The particles and rotating liquid are fully mixed, and the paint liquid is separated under the action of centrifugal force. The water carrying the waste gas dust flows back into the water tank 8, and the remaining air carrying the waste gas dust enters the cyclone barrel 5.

[0029] Dust separation: The cyclone tank 5 is equipped with a water pump for circulating water supply. The water source is the water tank 8, which is sprayed out by the nozzle. The dust particles in the exhaust gas sink back into the water tank 8 with the water flow. The separated gas enters the air outlet 6. The air outlet 6 is filled with a water-proof layer. The gas passes through the water-proof layer to remove the moisture in the air, and finally enters the external exhaust gas treatment equipment through the air outlet 7.

[0030] like Figures 3-4 As shown, a card plate 9 is fixed to the inner side wall of the cabinet 1. The buffer assembly includes a frame 10, which is snapped onto the card plate 9. The frame 10 is U-shaped, with the open end of the frame 10 located below the air outlet 7. A mesh 11 is fixed inside the frame 10, which is used to buffer the water flow.

[0031] The frame 10 is installed above the water tank 8 with the support of the card plate 9. The shape of the frame 10 increases the area of ​​the grid 11. The water curtain falls onto the grid 11, and the grid 11 divides the water, reducing the impact of the water hitting the water in the water tank 8, reducing noise, and preventing splashing.

[0032] like Figures 3-4 As shown, the cleaning component includes a non-woven fabric 12, which is laid on the bottom of the inner wall of the water tank 8. A support column 31 is fixed to the bottom of the air inlet 3. A notch 14 is opened on the non-woven fabric 12, and the support column 31 passes through the notch 14. The notch 14 passes through one end of the non-woven fabric 12.

[0033] The water flow inside cabinet 1 will eventually converge into the sink 8. Non-woven fabric 12 is laid against the bottom of the sink 8. When dust enters the sink 8 with the water flow, the dust will fall onto the non-woven fabric 12 and be absorbed on the surface of the non-woven fabric 12, preventing the dust from contacting the bottom of the sink 8. When cleaning the sink 8, the non-woven fabric 12 can be replaced directly, making cleaning convenient. Since the air outlet 7 needs to be supported by the support column 31, a notch 14 is made in the non-woven fabric 12. The notch 14 is installed opposite the support column 31 to facilitate the laying of the non-woven fabric 12.

[0034] like Figures 3-4 As shown, the upper surface of the nonwoven fabric 12 is embossed with multiple sets of protrusions 13, and the inner side wall of the cabinet 1 is fixed with a pressing assembly, the lower end of the pressing assembly is pressed onto the nonwoven fabric 12.

[0035] The protrusion 13 increases the barrier properties of the nonwoven fabric 12 surface, so that large clumps of gelatinous impurities formed by dust can be blocked, preventing these impurities from entering the water tank 8 and preventing the impurities from flowing with the water.

[0036] like Figure 4 As shown, the pressing assembly includes a fixing plate 15, which is fixed to the inner side wall of the cabinet 1. A pull rod 16 is inserted through the fixing plate 15. A pressure plate 17 for pressing the non-woven fabric 12 is fixed to the lower end of the pull rod 16. A spring 18 is sleeved on the side wall of the pull rod 16. One end of the spring 18 is fixed to the lower end of the fixing plate 15, and the other end is fixed to the upper end of the pressure plate 17.

[0037] When the non-woven fabric 12 is laid in the water, it is easy for the edges to lift up due to the water flow, which will cause the non-woven fabric 12 to not fit well with the bottom of the water tank 8. The spring 18 is used to squeeze the pressure plate 17, so that the pressure plate 17 presses the corners of the non-woven fabric 12 tightly, locking the non-woven fabric 12 at the bottom of the water tank 8 and preventing the non-woven fabric 12 from lifting up and causing misalignment. When removing or installing the non-woven fabric 12, simply pull the pull rod 16 to detach the pressure plate 17 from the non-woven fabric 12, which makes it easy to replace the non-woven fabric 12.

[0038] like Figure 1 and Figure 5As shown, a fixing seat 19 is fixedly connected to the inner side wall of the cabinet 1. A filter shell 20 is fixedly installed on the fixing seat 19. A filter screen 22 and an activated carbon layer 21 are fixedly connected inside the filter shell 20. A water inlet pipe 23 and a water outlet pipe 24 are respectively connected and fixedly connected to both ends of the filter shell 20. The water inlet pipe 23 is inserted into the water tank 8.

[0039] The water pump in this water curtain cabinet needs to be filtered. The pump is connected to the outlet pipe 24 and the inlet pipe 23 is inserted into the water tank 8. When the pump draws water, the water passes through the filter screen 22 and the activated carbon layer 21 to remove impurities and odors from the water. The water pumped out is used to add to the vortex emulsification chamber 4 and the cyclone tank 5, etc., so that the water flow in this water curtain cabinet is circulated.

[0040] The working principle of the environmentally friendly cyclone water curtain cabinet provided by this utility model is as follows:

[0041] Air carrying paint powder and other particles enters the cabinet 1, first contacting the water curtain, then entering the air inlet 3. The water curtain knocks some of the particles into the water tank 8. The air then enters the vortex emulsification chamber 4, and then the vortex bucket 5. The vortex inside both chambers mixes the air with the water flow. Impurities in the air re-enter the water tank 8 with the water flow. After treatment, the air is discharged through the air outlet 7 of the air outlet 6. The mesh 11 reduces the impact of the water flow entering the water tank 8, reduces water flow noise, and prevents water splashing. The non-woven fabric 12 facilitates the cleaning of particulate impurities collected in the water tank 8, reducing the difficulty of cleaning the water tank 8.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
