Abstract

This utility model discloses an automatic paint mist recovery device, including an outer casing and an air inlet pipe. The outer casing contains several paint mist collecting plates, and a filter plate is located to the right of each collecting plate. The collecting plates are repeatedly bent at angles of 90 to 120 degrees and have multiple collecting surfaces. Several air inlets are connected to the outer casing, and each inlet contains several accelerating plates positioned corresponding to the collecting plates. The accelerating plates have concave centers on their two surfaces to narrow the flow path of paint mist towards the collecting plates. Space is reserved between the collecting plates, allowing the paint mist to continuously collide with them during its flow. Airborne paint mist will collide with and adhere to the collecting plates, achieving multiple collection of paint mist. The reserved space does not excessively affect the flow of paint mist, and the paint mist collection efficiency will not significantly decrease over long-term use.

Description

Technical Field

[0001] This utility model relates to the field of paint mist capture technology, specifically an automatic paint mist recovery device. Background Technology

[0002] Spray painting is widely used. During spraying, the paint is atomized into paint mist under high pressure. Some of the mist will drift into the air. In order to avoid problems such as fogging pollution and spraying impact, paint mist needs to be treated.

[0003] In related technologies, a search revealed a composite paint mist collection box (publication number CN218608657U) that includes a drawer, a suction fan, an air collection box, an air outlet, a filter, a paint mist filter, and activated carbon. When collection begins, the suction fan draws the paint mist through circular holes into the object-proof screen, which filters larger foreign objects outside the main body. The paint mist then enters the air collection box through the suction pipe and the suction fan, and is then evenly blown into the filter through multiple air outlets. Paint mist that does not pass through the filter is filtered into the drawer below, while paint mist that passes through the filter enters the next paint mist filter. Paint mist that does not pass through the next filter is then filtered into the drawer below. Paint mist and gas that pass through the paint mist filter are adsorbed by the activated carbon, thus improving the treatment of paint mist.

[0004] However, the above solution uses a multi-layered structure of sealing gaskets, paint mist filters, and activated carbon to treat paint mist, which leads to poor paint mist flow. As the usage time increases, the paint mist treatment efficiency will gradually decrease, requiring frequent replacement of sealing gaskets, paint mist filters, and activated carbon. Utility Model Content

[0005] The purpose of this invention is to provide an automatic paint mist recovery device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic paint mist recovery device, comprising an outer casing, inside which are arranged several paint mist collecting plates, and a filter plate located to the right of the paint mist collecting plates in the outer casing. The paint mist collecting plates are in a repeatedly bent shape with a bending angle of 90 degrees to 120 degrees. The paint mist collecting plates have several collecting surfaces. When the paint mist flows, it is collected by the paint mist collecting plates. The channels between the paint mist collecting plates do not excessively obstruct the flow of paint mist, resulting in high paint mist treatment efficiency.

[0007] The air intake pipe has several sections and is connected to the outer casing. Inside the air intake pipe are several accelerator plates, which are positioned corresponding to the paint mist collection plates. The two surfaces of the accelerator plates are concave in the middle to narrow the flow path of the paint mist to the two paint mist collection plates. When the paint mist first enters the outer casing, it can accelerate the flow of the paint mist, and the paint mist directly hits the paint mist collection plates, which is conducive to the paint mist collection plates quickly collecting the paint mist.

[0008] Furthermore, a protective pad is provided on the lower surface of the outer casing, which can protect the outer casing and prevent wear and tear.

[0009] Furthermore, the outer casing is connected to an extraction pipe, the extraction pipe is connected to a fan, the fan is connected to an exhaust pipe, and the end of the extraction pipe is provided with a flexible sealing ring. The extraction of paint mist is achieved through the fan, which can accelerate the recovery of paint mist and also recover gas.

[0010] Furthermore, several fixing rods are inserted into several paint mist collection plates to position the paint mist collection plates and prevent them from shifting.

[0011] Furthermore, the sealing ring is connected to a flow guide, which can deliver the paint mist to the outer casing, making it convenient for two outer casings to be used together.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) Space is reserved between several paint mist collection plates. During the flow of paint mist, it continuously impacts the paint mist collection plates. Paint mist in the air will collide with and adhere to the paint mist collection plates, realizing multiple collection of paint mist. The reserved space will not excessively affect the flow of paint mist, and the paint mist collection efficiency will not be significantly reduced during long-term use.

[0014] (2) After the paint mist collection plate collects a large amount of paint mist, the paint will flow downward to the bottom of the outer box. This avoids the paint being too thick and blocking the flow of paint mist. By making full use of the paint mist collection plate, more paint mist can be captured, which can extend the replacement cycle of the paint mist collection plate.

[0015] (3) Two accelerator plates can reduce the flow space of paint mist and increase the air flow speed. Due to inertia, the paint mist can better collide with the collection surface. The air rebounds from the collection surface and continues to flow. Multiple collection surfaces can efficiently collect paint mist. Attached Figure Description

[0021] 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 protection scope of the present utility model.

[0022] Example:

[0023] Please see Figure 1-4 This utility model provides a technical solution: an automatic paint mist recovery device, including an outer box 5. The outer box 5 is provided with several paint mist collecting plates 11. The paint mist collecting plates 11 can be made of glass fiber. A plastic mesh frame is set on the glass fiber to shape the glass fiber. The outer box 5 is provided with a filter plate 10 located on the right side of the paint mist collecting plates 11. The filter plate 10 can be a labyrinth filter paper. Paint mist that is not collected by the paint mist collecting plates 11 is blocked by the filter plate 10. The paint mist collecting plates 11 are in a repeatedly bent shape with a bending angle of 90 degrees to 120 degrees. The paint mist collecting plates 11 have several collecting surfaces 12. During the bending and flowing process of the paint mist, the paint mist will hit the collecting surface 12 each time it bends, thus achieving effective collection of the paint mist.

[0024] The air intake pipe 7 is provided in several parts and is connected to the outer casing 5. The air intake pipe 7 is provided with several accelerator plates 8 inside. The positions of the accelerator plates 8 correspond to the paint mist collection plates 11. The two surfaces of the accelerator plates 8 are concave in the middle to narrow the flow channel of paint mist to the two paint mist collection plates 11, thereby increasing the flow speed of air and paint mist, so that the paint mist collides with the collection surface 12 quickly and improves the paint mist collection efficiency.

[0025] In this embodiment, as Figure 2 As shown, the lower surface of the outer box 5 is provided with a protective pad 9. The protective pad 9 can prevent the outer box 5 from being worn and can also prevent the outer box 5 from getting damp when the ground is wet.

[0026] In this embodiment, as Figure 1 As shown, the outer casing 5 is provided with a sealing ring 6. The sealing ring 6 is located around the air intake pipe 7. The sealing ring 6 is elastic. When the air guide 14 expands the sealing ring 6, it improves the sealing performance of the connection between the outer casing 5 and the air guide 14.

[0027] In this embodiment, as Figure 1 As shown, the outer casing 5 is connected to an extraction pipe 3, the extraction pipe 3 is connected to a fan 2, the fan 2 is connected to an exhaust pipe 1, and the air discharged from the exhaust pipe 1 with a certain temperature and humidity can be reused.

[0028] In this embodiment, as Figure 1 As shown, the end of the extraction tube 3 is provided with a flexible sealing ring 4. The flexible sealing ring 4 can deform when in contact with the outer box 5, thereby reducing the gap between the outer box 5 and the extraction tube 3 and achieving a good sealing effect.

[0029] In this embodiment, as Figure 3 As shown, several fixing rods 13 are inserted into several paint mist collection plates 11. The fixing rods 13 can position the multiple paint mist collection plates 11 and prevent the paint mist collection plates 11 from shifting.

[0030] In this embodiment, as Figure 4 As shown, the sealing ring 6 is connected to a flow guide shroud 14, which collects the air containing paint mist inside the spray booth, and the paint mist is then diverted into the outer casing 5.

[0031] Specifically, when in use, after the fan 2 is started, the fan 2 draws in air, and the air containing paint mist in the spray booth flows from the guide shroud 14 to the air inlet pipe 7. Several air inlet pipes 7 divert the paint mist, so that the paint mist flows evenly into the outer box 5. When the air containing paint mist flows through the accelerator plate 8, the accelerator plate 8 reduces the air flow diameter, increases the flow speed of air and paint mist, and makes the paint mist directly hit the collection surface 12.

[0032] Because the two adjacent paint mist collecting plates 11 have bent flow channels, the paint mist continuously collides with the collecting surface 12 during the paint mist flow process. While ensuring the flow of paint mist, it achieves efficient collection of paint mist. Long-term use will not cause clogging problems, ensuring the stability of paint mist collection efficiency. A small portion of paint mist that is not collected by the collecting surface 12 is blocked by the filter plate 10, thus achieving paint mist collection. After the air flows through the filter plate 10, it enters the extraction pipe 3. The fan 2 sends the air out from the exhaust pipe 1. The exhaust air can be adjusted by the constant temperature and humidity equipment and then flow back into the spray booth for reuse, realizing the recycling of air.

[0033] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
