Description

Technical Field

[0001] This utility model relates to the field of water curtain cabinet technology, and discloses a multi-faceted water curtain cabinet. Background Technology

[0002] In industrial production and furniture manufacturing, spray painting is a very common process. However, the spray painting process generates a large amount of paint mist, which contains not only volatile organic compounds (VOCs) but also particulate matter such as pigments and resins. If directly emitted without effective treatment, it can seriously harm the health of operators, and long-term inhalation may cause respiratory diseases, allergic reactions, and other health problems. To solve the problem of paint mist treatment, water curtain cabinets are widely used as a common paint mist purification device.

[0003] Traditional water curtain booths are mostly single-sided structures, forming a water curtain to intercept paint mist in only one direction. However, in actual painting operations, paint mist often diffuses in multiple directions. Single-sided water curtain booths, due to their limited interception area, struggle to capture paint mist from all directions, leading to some paint mist escaping and resulting in unsatisfactory purification effects. Existing water curtain booths also have shortcomings in water curtain formation and filtration efficiency. Most can only form a single-stage or a few-stage water curtain, limiting the number of times paint mist can be filtered, making it difficult to fully capture some fine particles in the paint mist.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

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 protection scope of the present utility model.

[0029] Please see Figure 1-5 A multi-faceted water curtain cabinet includes: a cabinet body 1, with an air outlet 101 at the top, which can be connected to an exhaust fan. During operation, a negative pressure environment is created at the bottom of the cabinet body 1, thereby drawing paint mist into the cabinet body 1. An arc-shaped water guide plate 102 is provided at the left end of the cabinet body 1, and a first overflow box 103 is provided on the upper right side of the arc-shaped water guide plate 102. The first overflow box 103 is fixedly connected to the cabinet body 1. During use, water is continuously poured into the first overflow box 103. After overflowing from the first overflow box 103, the water flows along the arc-shaped water guide plate 102, thus forming a water curtain to initially intercept the paint mist on the right side. A side panel 2 is fixedly connected to the left rear end of the cabinet body 1, and the upper rear end of the side panel 2 is fixed. A second overflow box 201 is connected. A water outlet groove 202 is opened on the surface of the side plate 2 at the same height as the upper end of the second overflow box 201. An extension plate 203 is fixedly connected to the front surface of the side plate 2 at the same level as the bottom end of the water outlet groove 202. When the water overflows from the second overflow box 201, it will flow down from the front end of the extension plate 203 to form a water curtain and intercept the paint mist behind it. A water collection base 3 is closed on all sides and has a drain outlet 301 on the right end surface. The water collection base 3 can collect the water flowing down from the water curtain and discharge it from the drain outlet 301 for easy recycling. The bottom ends of the water curtain cabinet 1 and the side plate 2 are both fixedly connected to the water collection base 3. A water curtain assembly 4 is set inside the water curtain cabinet 1 and is used for multi-stage filtration of paint mist.

[0030] Specifically, an inclined plate 302 is provided inside the water collection base 3 at the corresponding position of the water curtain cabinet 1, and the inclined plate 302 is inclined.

[0031] Through the above technical solution, the inclined plate 302 can guide the water flowing from the water curtain cabinet 1 into the water collection base 3.

[0032] Specifically, the bottom of the water curtain cabinet 1 has two symmetrical water collection plates 105, which are inclined and fixedly connected to each other by a water outlet pipe 106.

[0033] Through the above technical solution, the two symmetrical and inclined water collection plates 105 can efficiently collect the water flowing down from the water curtain assembly 4. The inclined design can use gravity to guide the water flow to converge in the middle, while the water outlet pipe 106 fixedly connected between the two can timely discharge the converged water, ensuring that the water flows smoothly into the water collection base 3 and avoiding water accumulation inside the water curtain cabinet 1.

[0034] Specifically, the water curtain assembly 4 includes a first water curtain plate 401, a second water curtain plate 402, a third water curtain plate 403, and a fourth water curtain plate 404 stacked vertically. The first water curtain plate 401 has a first hanging rod 405 fixedly connected to both the front and rear sides of its left end. The upper and lower ends of the first hanging rod 405 are respectively fixedly connected to the water curtain cabinet 1 and the second water curtain plate 402. A second hanging rod 406 is fixedly connected between the second water curtain plate 402 and the third water curtain plate 403, and a third hanging rod 407 is fixedly connected between the third water curtain plate 403 and the fourth water curtain plate 404. The first water curtain plate 401, the second water curtain plate 402, the third water curtain plate 403, and the fourth water curtain plate 404 are all inclined, with adjacent water curtain plates having opposite inclination directions. During use, water flows down from the four water curtain plates sequentially, forming four water curtains to filter paint mist four times.

[0035] Through the above technical solution, the multi-stage water curtain structure formed by the water curtain assembly 4 provides multiple filtration paths for the paint mist. The design of adjacent water curtain plates with opposite inclination directions can change the flow trajectory of the paint mist, prolong the contact time and contact area between the paint mist and the water curtain, and allow the paint mist to mix more thoroughly with the water flow. The combination of these two factors significantly improves the purification effect of the paint mist, ensuring that the treated air is cleaner.

[0036] Specifically, a reinforcing plate 6 is installed inside the water curtain cabinet 1 at the same height as the first water curtain panel 401. The bottom end of the reinforcing plate 6 is fixedly connected to the first hanging rod 405, which can fix the first hanging rod 405. A crossbeam 107 is installed at the bottom of the inner side of the water curtain cabinet 1. The bottom end of the third hanging rod 407 is fixedly connected to the crossbeam 107, which can increase the stability of the third hanging rod 407.

[0037] The above technical solution can enhance the overall structural stability of the water curtain assembly 4 composed of each water curtain plate and each hanger, prevent the water curtain plate from shaking or shifting during water flow impact and equipment operation, ensure the uniform and stable formation of the four-stage water curtain, and guarantee continuous and efficient filtration of paint mist.

[0038] Specifically, a baffle plate 104 is provided at the upper part of the interior of the water curtain cabinet 1, and the baffle plate 104 extends into the interior of the first overflow box 103.

[0039] Through the above technical solution, the baffle plate 104 can maintain the stability of the water level inside the first overflow box 103, while maintaining the state of the water curtain.

[0040] Specifically, a gas collecting plate 5 is installed below the water curtain cabinet 1. The gas collecting plate 5 is an arc-shaped plate and its upper end is fixedly connected to the water collecting plate 105.

[0041] Through the above technical solution, the arc-shaped air collection plate 5 can use its arc-shaped structure to guide the paint mist to be drawn more smoothly into the interior of the water curtain cabinet 1, thereby enhancing the concentration effect of the paint mist.

[0042] In use, two multi-sided water curtain cabinets are symmetrically arranged to form a closed spraying space, and an exhaust fan is connected to the air outlet 101. Water is then introduced into the first overflow box 103, the second overflow box 201, and the first water curtain plate 401. The water in the first overflow box 103 flows down along the arc-shaped water guide plate 102 to form a water curtain, and the water in the second overflow box 201 flows out to form a side water curtain. At the same time, the first to fourth water curtain plates of the water curtain assembly 4 form a four-stage water curtain through the water flow. The paint mist generated by spraying is guided by the arc-shaped air collecting plate 5 and sucked into the water curtain cabinet 1 under the action of the exhaust fan. It passes through the four-stage water curtain filtration in sequence. After the paint mist and water flow are fully mixed, the water is collected by the water collecting plate 105 and flows into the water collecting base 3 through the water outlet pipe 106. The inclined plate 302 in the water collecting base 3 guides the water flow to the drain outlet 301, while the purified air is discharged from the air outlet 101, completing the paint mist treatment cycle.
