Description

Technical Field

[0001] This utility model relates to the field of industrial coating technology, and in particular to a powder spraying booth with a self-cleaning function. Background Technology

[0002] Powder coating booths are used for spraying sheet metal parts and other workpieces. In the coating industry, powder is extremely harmful to human health, making automatic color-changing booths crucial. Even so, quick color-changing booths still require manual entry to clean powder adsorbed on the booth surface due to electrostatic discharge when changing colors. This results in large-area contact between the coating personnel and the powder, making it inevitable that powder will enter the respiratory system and significantly harm their health. Existing powder coating booths are mostly square in design, requiring manual cleaning for powder recovery, which is very slow. Furthermore, cleaning the four corners of the square booth is often incomplete, affecting color changes. Traditional powder coating booths are slow to clean and recover powder, resulting in incomplete recovery and increased labor costs. Therefore, solutions to these problems are needed.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-5 This utility model discloses a powder spraying booth with a self-cleaning function, comprising a main body 1 and a collection box 2 installed on one side of the main body 1. The main body 1 facilitates the installation of a sealing mechanism and a cleaning mechanism. The main body 1 has first mounting grooves at both its front and rear ends, and placement grooves 3 on both sides for placing spray guns. The placement grooves 3 facilitate the placement of spray guns. Protrusions 6 for fitting into the placement grooves 3 are installed outside the placement grooves 3. A sealing mechanism is installed on the outside of the main body 1, and a cleaning mechanism is installed inside the main body 1. The cleaning mechanism includes an exhaust component and a cleaning component. A cylindrical cavity is formed inside the main body 1, with the bottom end of the cylindrical cavity shaped like an inverted funnel, facilitating dust collection. A conical diverter 4 is installed at the bottom end of the cylindrical cavity, which helps to collect dust. The powder is disposed of in the main body 1. The main body 1 has a first cavity and a second cavity at its bottom. The sealing mechanism includes a first sliding door 5 installed in the first mounting groove at the front and rear ends and a second mounting groove opened above the placement groove 3. A second sliding door 7 is slidably installed in the second mounting groove. The first sliding door 5 and the second sliding door 7 facilitate the sealing device. A protrusion 6 is located inside the second sliding door 7. The exhaust assembly includes a blower 9 connected to the first cavity and an air extractor 10 connected to the second cavity. The blower 9 facilitates the injection of high-pressure gas into the distribution plate 4. The air extractor 10 facilitates the extraction of powder from the cavity. The air outlet of the air extractor 10 is connected to a connecting pipe 15. The connecting pipe 15 facilitates the delivery of the extracted powder to the collection box 2. The other end of the connecting pipe 15 is connected to the collection box 2.

[0020] In this invention, a gas supply pipe 11 is inserted into the top surface of the distribution plate 4, which facilitates the transmission of high-pressure gas. A jet pipe 12 is installed at the top of the gas supply pipe 11, which facilitates the downward jetting of gas. A jet groove is provided at the bottom of the jet pipe 12. The cleaning assembly includes the gas supply pipe 11 and a motor 8 installed at the bottom of the distribution plate 4, which facilitates the rotation of the distribution plate 4. The bottom of the motor 8 is fixed to the bottom of the main body 1 by a fixing block. Multiple jet nozzles 14 facing the inner wall of the cylindrical cavity are installed at equal intervals on the gas supply pipe 11, which facilitates the blowing of air onto the inner wall of the cavity during cleaning. A scraper 13 is installed on the gas supply pipe 11, which facilitates the scraping off of powder adsorbed on the inner wall. One end of the scraper 13 abuts against the inner wall of the cavity.

[0021] Working principle: When using this utility model, the spray gun is placed in the placement slot 3, and the material enters and exits through the first sliding doors 5 at both ends. When cleaning the powder spraying chamber is required, the first sliding door 5 and the second sliding door 7 are closed, at which point the main body 1 is sealed. At this time, the motor 8 and the blower 9 are turned on. The motor 8 drives the distribution plate 4 to rotate, and the distribution plate 4 drives the air delivery pipe 11 and the upper jet pipe 12 to rotate. At the same time, the scraper 13 scrapes off the powder adsorbed on the inner wall. At this time, the blower 9 generates high-pressure gas, which is transmitted to the distribution plate 4 through the first cavity. The gas is then transported through the air supply pipe 11 to the jet pipe 12 and the jet head 14. The jet pipe 12 sprays high-pressure gas from top to bottom. While the scraper 13 rotates, the jet head 14 blows air onto the inner wall of the cavity. At this time, a vortex airflow will be formed in the cavity. The vacuum pump 10 is turned on, and the strong suction draws out the air mixed with powder through the gap between the second cavity and the diverter plate 4 and the bottom of the cavity. The air is then transported to the collection box 2 for recycling through the connecting pipe 15. After cleaning, the device is reset, the motor 8, the blower 9 and the vacuum pump 10 are turned off, and the power is disconnected.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
