Description

Technical Field

[0001] The utility model relates to the technical field of paint mist collection and treatment equipment, and particularly relates to a new paint mist collection and treatment tower after spraying. Background Technique

[0002] In machining, parts need to be painted or baked. The gas during spraying contains harmful substances. Direct emission will form photochemical smog, and some can damage the ozone layer, causing serious pollution to the atmospheric environment. It is necessary to collect and treat the paint mist.

[0003] For example, the published document with the application number 202123226282.1 discloses a paint mist scrubbing tower for paint mist treatment. This utility model is designed according to existing requirements. The paint mist entering from the feed pipe can rise spirally along the spiral guide vane, reducing the accumulation of paint mist at the feed pipe. At the same time, during the process of the paint mist rising spirally along the spiral guide vane, it effectively contacts the adsorption liquid, thereby completing the washing treatment in the spray tank. After that, the adsorbent can perform secondary adsorption treatment on the paint mist after spray treatment, improving the quality of paint mist treatment. However, in the process of using this paint mist collection and treatment tower, by spraying the adsorption liquid to adsorb the paint mist in the air, it is difficult to ensure that the sprayed adsorption liquid is fully and comprehensively in complete contact with the paint mist in the air, which will cause some air to carry the paint mist and rise and escape, thus making it difficult to ensure the quality and comprehensiveness of the treatment, and continuously injecting the adsorption liquid will also lead to a large amount of waste, increasing the use cost.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a new paint mist collection and treatment tower after spraying is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a new paint mist collection and treatment tower after spraying to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A new paint mist collection and treatment tower after spraying, including an adsorption chamber. A one-way valve inlet pipe is installed below the left side of the outer surface of the adsorption chamber. The inside of the adsorption chamber is filled with an adsorption liquid. A suction pump is fixedly arranged on the right side of the outer surface of the adsorption chamber. One end of the suction pump is fixedly connected with a delivery pipe. A spraying ring is fixedly installed above the inner surface of the adsorption chamber. The delivery pipe penetrates the adsorption chamber and is communicated with the spraying ring.

[0007] Preferably, a sealing rubber ring hole is opened in the middle of the upper end of the adsorption chamber, and a sealing cover is threadedly connected to the lower end of the adsorption chamber.

[0008] Preferably, a filter chamber is provided above the adsorption chamber. Ring plates of the same shape and size are fixedly installed around the opposite ends of the surfaces of the adsorption chamber and the filter chamber. The adsorption chamber and the filter chamber are fixedly connected by bolts through the ring plates.

[0009] Preferably, a connecting pipe is fixedly installed through the lower end of the filter chamber, and the connecting pipe can be just inserted into the adsorption chamber by fitting inside the sealing rubber ring hole.

[0010] Preferably, a fixed box is fixedly installed in the middle of the inner surface of the filter chamber, and through holes are evenly distributed on the surface of the fixed box.

[0011] Preferably, adsorption cotton is fixedly arranged on the inner surface of the fixed box, and the fixed box and the adsorption cotton match the shape of the filter chamber.

The gas carrying the paint mist is injected into the adsorption liquid for full mixing and adsorption. The gas will rise. At the same time, the suction pump will suck the adsorption liquid and inject it into the spraying ring through the delivery pipe for spraying, forming a water mist barrier of the adsorption liquid above the adsorption chamber for further secondary adsorption treatment of the paint mist not fully adsorbed in the rising gas, greatly improving the quality of the paint mist treatment. And this method can fully recycle the adsorption liquid, avoid waste of the adsorption liquid and reduce costs.

[0015] 2. Through the settings of the sealing rubber ring hole, the ring plate and the connecting pipe in the present utility model, the adsorption chamber and the filter chamber can be quickly and conveniently disassembled and assembled by using the ring plate, which is convenient for separate modular maintenance and replacement, without the need to maintain the entire device at one time.

[0016] 3.

In the filter chamber, the trace paint mist carried in the air will be adsorbed and captured by the adsorption cotton and the capture carbon plate through the through holes, so as to ensure complete and thorough filtration of the paint mist.

[0022] As Figures 1-3 shown, a new type of paint mist collection and treatment tower after painting includes an adsorption chamber 1. A one-way valve intake pipe 2 is installed below the left side of the outer surface of the adsorption chamber 1. The inside of the adsorption chamber 1 is filled with an adsorption liquid 3. A suction pump 4 is fixedly arranged on the right side of the outer surface of the adsorption chamber 1. One end of the suction pump 4 is fixedly connected to a delivery pipe 5. A spraying ring 6 is fixedly installed above the inner surface of the adsorption chamber 1. The delivery pipe 5 penetrates through the adsorption chamber 1 and is communicated with the spraying ring 6.

[0023] By adopting the above technical solution, the air carrying the paint mist enters the inside of the adsorption chamber 1 through the one-way valve intake pipe 2; the adsorption liquid 3 will be fully mixed and adsorbed with most of the paint mist; the suction pump 4 will suck the adsorption liquid 3 and inject it into the spraying ring 6 through the delivery pipe 5 for spraying, forming a water mist barrier of the adsorption liquid 3 above the adsorption chamber 1 to further perform secondary adsorption treatment on the paint mist that is not fully adsorbed in the rising gas.

[0024] Furthermore, a sealing rubber ring hole 7 is opened in the middle of the upper end of the adsorption chamber 1. The lower end of the adsorption chamber 1 is threadedly connected with a sealing cover 8; a rubber ring is fixedly installed at the opening part of the sealing rubber ring hole 7.

[0025] By adopting the above technical solution, the sealing cover 8 can be opened and closed to discharge and replace the adsorption liquid 3.

[0026] Furthermore, a filtration chamber 9 is arranged above the adsorption chamber 1. Ring plates 10 of the same shape and size are fixedly installed around the opposite ends of the surfaces of the adsorption chamber 1 and the filtration chamber 9. The adsorption chamber 1 and the filtration chamber 9 are fixedly connected by bolts through the ring plates 10.

[0027] By adopting the above technical solution, the adsorption chamber 1 and the filtration chamber 9 are connected to jointly form a treatment tower.

[0028] Furthermore, a connecting pipe 11 is fixedly installed through the lower end of the filtration chamber 9, and the connecting pipe 11 can be just inserted into the inside of the adsorption chamber 1 by fitting and inserting it into the inner side of the sealing rubber ring hole 7.

[0029] By adopting the above technical solution, the connecting pipe 11 is inserted into the sealing rubber ring hole 7 and is in close contact with the sealing rubber ring hole 7. The rubber ring can be used to seal the connecting joint to avoid gas leakage.

[0030] Furthermore, a fixed box 12 is fixedly installed in the middle of the inner surface of the filtration chamber 9, and through holes 13 are evenly distributed on the surface of the fixed box 12.

[0031] By adopting the above technical solution, when the gas enters the filtration chamber 9, it will enter the inside of the fixed box 12 through the through holes 13.

[0032] Furthermore, an adsorption cotton 14 is fixedly arranged on the inner surface of the fixed box 12, and the fixed box 12 and the adsorption cotton 14 are matched with the shape of the filtration chamber 9.

[0035] By adopting the above technical solution, the capture carbon plate 15 is the same as the adsorption cotton 14, and filters and adsorbs the paint mist; the filtered air will be discharged through the exhaust port 16.

[0036] Working principle: When using this new type of paint mist collection and treatment tower after painting, first, the ring plate 10 can be used to quickly install the adsorption chamber 1 and the filtration chamber 9. During installation, the connecting pipe 11 will be inserted into the sealing rubber ring hole 7 to connect the adsorption chamber 1 and the filtration chamber 9. Then, the air carrying the paint mist enters the interior of the adsorption chamber 1 through the one-way valve intake pipe 2, and the gas carrying the paint mist is injected into the adsorption liquid 3 for full mixing and adsorption. The gas will rise. At the same time, the suction pump 4 will suck the adsorption liquid 3 and inject it into the spraying ring 6 through the delivery pipe 5 for spraying, forming a water mist barrier of the adsorption liquid 3 above the adsorption chamber 1 for further secondary adsorption treatment of the paint mist not fully adsorbed in the rising gas. After the adsorption in the adsorption chamber 1, the gas will enter the filtration chamber 9 through the connecting pipe 11. In the filtration chamber 9, the trace paint mist carried in the air will be adsorbed and captured by the adsorption cotton 14 and the capture carbon plate 15 through the through holes 13, thus ensuring complete and thorough filtration of the paint mist. At this time, the air can be discharged through the discharge port 16. Unscrew the sealing cover 8 to replace and discharge the adsorption liquid 3. This is the working principle of this new type of paint mist collection and treatment tower after painting.
