Description

A water curtain cabinet

Technical Field

The utility model relates to the technical field of water curtain cabinets, in particular to a water curtain cabinet.

Background technique

A sprayer is a special coating equipment that uses spraying technology. When working, the sprayer pressurizes the inhaled paint and transports the paint to the spray gun of the sprayer through a high-pressure hose. The spray gun instantly atomizes the paint and releases it onto the surface of the object to be coated.

When spraying paint with a spray gun, a large amount of viscous atomized gas (such as water-soluble gases such as paint) will be generated. These atomized gases can easily cause physical harm to workers, so they are usually extracted and discharged into a water curtain cabinet for purification by a fan. However, the sticky particles in the atomized gas will adhere to the fan, and the fan needs to be disassembled and cleaned frequently, which is labor-intensive and costly.

Detailed ways

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

As shown in Figure 1, the utility model provides an embodiment of a water curtain cabinet, including: an air inlet pipe 1, the upper end of the air inlet pipe 1 is an air inlet end, and the lower end is an air outlet end, the air outlet end of the air inlet pipe 1 is connected to the input end of an axial flow fan 3 and is fixed with a clamp, and the air inlet end of the air inlet pipe 1 is detachably installed with an adsorption core 2, and the adsorption core 2 is used for pre-filtering atomized gas.

Specifically, the adsorption core 2 can be made of materials with adsorption functions such as activated alumina materials and adsorption resins. Preferably, the adsorption core 2 is activated carbon. Activated carbon has a large surface area and rich pore structure, which enables it to effectively adsorb various gases, solutions and particulate substances. Its large number of micropores and mesopores can effectively increase the adsorption efficiency; activated carbon can remove adsorbed substances and restore to a higher adsorption capacity after desorption and high-temperature regeneration, and can be recycled to have a longer service life, thereby reducing replacement costs and impact on the environment; activated carbon is usually made of natural non-toxic materials, has no chemical reactivity, and is more safe.

In this embodiment, the atomized gas entering the axial flow fan 3 is pre-filtered by the adsorption core 2. During the pre-filtration, the sticky particles in the atomized gas are adsorbed by the adsorption core 2, so that the gas entering the axial flow fan 3 is cleaner, thereby greatly reducing the sticky particles attached to the axial flow fan 3, making it easy to reduce the cleaning frequency of the axial flow fan 3 and reduce costs.

The output end of the axial flow fan 3 is connected to the air inlet end of the exhaust pipe 4 and fixed with a clamp. The air outlet end of the exhaust pipe 4 is connected to the air inlet of the water tank 5 and is also fixed with a clamp. Clean water is set in the water tank 5. The water tank 5 has a water inlet 12 and a drain valve 7, and a top cover 8 is set on the water tank 5.

Specifically, the water tank 5 is fixed with a water pump 11 by bolts, and a wall 6 is welded inside the water tank 5. The wall 6 has a plurality of through holes, wherein the clean water level in the water tank 5 is higher than the bottom of the wall 6, so that the gas entering the water tank 5 from the exhaust pipe 4 is not easy to flow out from the gap between the clean water level and the wall 6, so that the gas only passes through the through holes. A water pipe is arranged on the top of the wall 6, and the water inlet of the water pipe is connected to the water outlet of the water pump 11 through a hose. The water flow ejected from the water pipe to the wall 6 from top to bottom forms a water curtain, and the outer surfaces on both sides of the wall 6 are covered by the water curtain.

Furthermore, a volume cavity is provided in the wall 6, and filter cotton 9 is provided in the volume cavity. A filter cover 10 is fixed to the top cover 8 by bolts. The portion where the filter cover 10 covers the top cover 8 is hollowed out so that the filter cover 10 is connected to the water tank 5. The filter cover 10 can adopt a louver filter mesh cover to facilitate filtering the passing gas and prevent external impurities from entering the water tank 5. The filter cover 10, filter cotton 9 and water curtain form a multi-stage filter unit, and the multi-stage filter unit performs multi-stage purification on the pre-filtered atomized gas.

In this embodiment, clean water is filled into the water tank 5 through the water inlet 12, the water inlet 12 is sealed with a sealing cover, the axial flow fan 3 is turned on, and the viscous atomized gas from the outside enters the air inlet pipe 1. After the adsorption core 2 at the air inlet end of the air inlet pipe 1 pre-filters the viscous particles in the gas, the pre-filtered gas enters the axial flow fan 3, and is then discharged into the water tank 5 through the exhaust pipe 4. The water pump 11 is turned on, and the water pump 11 transports the clean water in the water tank 5 to the water pipe on the top of the wall 6. The water pipe sprays water from top to bottom toward the wall 6, and the water flow forms a water curtain. The outer surfaces of both sides of the wall 6 are covered with the water curtain. The filter cotton 9 is covered so that there is a layer of water curtain on each side. The pre-filtered gas entering the water tank 5 passes through the first water curtain (the water curtain on the left side of the filter cotton 9) under the action of air pressure for one purification. The gas after one purification flows through the filter cotton 9 for the second purification. Then the gas flows out from the second water curtain (the water curtain on the right side of the filter cotton 9) for the third purification. The gas after the three purifications flows through the filter cover 10 to achieve the fourth purification. The gas after the four purifications is discharged from the filter cover 10 to the outside, so that the viscous atomized gas is fully purified, greatly reducing its pollution to the environment.

It can be understood that after the water tank 5 is filled with clean water from the water inlet 12, the water in the water tank 5 is pumped into the water pipe on the top of the wall 6 by the water pump 11, and the water pipe sprays water from top to bottom toward the wall 6. The water forms a water curtain on the surface of the wall 6, and the water flows back into the water tank 5, and is then circulated and pumped by the water pump 11 to realize the water circulation inside the water tank 5, which saves water resources. The clean water in the water tank 5 can be discharged regularly through the drain valve 7 and then refilled with clean water.

In addition, the water curtain cabinet can replace the adsorption core 2, the filter cotton 9 and the filter cover 10, thereby extending the service life of the equipment.

In another embodiment, a filter screen may be provided in the water pump 11 to prevent impurities in the water flow from clogging the water pump 11 .

Working principle: Fill the water tank 5 with clean water through the water inlet 12, seal the water inlet 12 with a sealing cover, turn on the axial flow fan 3, and the viscous atomized gas from the outside enters the air inlet pipe 1. The adsorption core 2 at the air inlet end of the air inlet pipe 1 pre-filters the viscous particles in the gas. The pre-filtered gas enters the axial flow fan 3 and is then discharged into the water tank 5 through the exhaust pipe 4. Turn on the water pump 11, and the water pump 11 transports the clean water in the water tank 5 to the water pipe on the top of the wall 6. The water pipe sprays water from top to bottom toward the wall 6. The water flows to form a water curtain. The outer surfaces on both sides of the wall 6 are covered by the water curtain, so that there is a layer of water curtain on each side of the filter cotton 9. The pre-filtered gas entering the water tank 5 is purified through the first water curtain under the action of air pressure. The gas after the first purification flows through the filter cotton 9 for the second purification. Then the gas flows out from the second water curtain for the third purification. The gas after the third purification flows through the filter cover 10 to achieve the fourth purification. The gas after the fourth purification is discharged from the filter cover 10 to the outside.

In summary, although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
