Description

Technical Field

[0001] This utility model relates to the field of powder coating technology, specifically a dust removal device for a powder coating booth. Background Technology

[0002] Powder coating refers to the process of uniformly spraying powder coating onto the surface of a workpiece using the principle of electrostatic adsorption, followed by high-temperature curing to form a protective or decorative coating. Powder coating of workpiece surfaces is usually carried out in a powder coating booth, and is combined with a powder recovery system equipped in the booth to recover the powder, thereby achieving the effect of reuse and avoiding powder spillage that pollutes the environment and causes explosions or other safety hazards.

[0003] Chinese utility model patent CN202221314989.X discloses a powder spraying booth. It uses an exhaust fan to draw dust from inside the booth into a dust collection box through a first ventilation duct. Airflow exits through an outlet, and dust particles in the airflow are filtered and retained in the dust collection box, thus cleaning the dust inside the booth and preventing it from escaping into the outside air and polluting the surrounding environment. While the dust is primarily adsorbed through the outlet, the accumulation of dust and grime towards the outlet relies mainly on airflow. This makes it difficult to remove large or fallen particles. Furthermore, the large space results in low cleaning efficiency, leading to a gradual increase in dust accumulation on the floor during processing, which can be easily stirred up again, affecting the powder spraying environment and posing safety hazards. Utility Model Content

[0022] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0023] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0024] Reference Figures 1-2 , Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is another structural schematic diagram of the present invention. A powder spraying booth cleaning device includes: a booth body 1, into which the product to be powder sprayed is transported, and then the workpiece is powder sprayed manually or by automated equipment; a cleaning seat 2 is disposed inside the booth body 1 and located at the bottom; a powder collecting surface 21 is provided on the side of the cleaning seat 2 near the inner cavity of the booth body 1; the powder collecting surface 21 is inclined from the outside to the center, so that the dust falling on the powder collecting surface 21 can automatically roll down along the powder collecting surface 21 towards the center; a conveying pipe 22 is provided inside the cleaning seat 2; one end of the conveying pipe 22 is located at the center of the powder collecting surface 21, and the other end of the conveying pipe 22 extends outside the cleaning seat 2; and the conveying pipe 22 is connected to an exhaust device, so that the conveying pipe 22 is under negative pressure, thereby drawing out the dust falling to the center of the powder collecting surface 21 by the conveying pipe 22, thereby achieving the effect of powder cleaning.

[0025] This dust removal device for the powder spraying booth features a dust collection surface that slopes from the outside to the center. This allows dust to automatically collect along the dust collection surface and be drawn outwards through the conveying pipe located in the center of the booth after falling onto the floor. This effectively cleans the dust inside the booth, avoiding the problems associated with traditional powder spraying booths that lack the ability to collect dust, leading to increased dust accumulation on the floor, easy stirring, and negative impacts on the spraying environment, thus posing safety hazards.

[0026] An air inlet 11 is provided on the side of the chamber 1 away from the dust collection seat 2, and a blower can be installed at the air inlet 11 to blow air into the chamber 1, so that the dust scattered in the air can be subjected to downward pressure and fall quickly onto the dust collection surface 21, thereby improving the dust removal efficiency.

[0027] Furthermore, the blowing position, force, and direction of the air inlet 11 can be adaptively controlled according to the area of ​​the chamber 1 and the setting of the processing position.

[0028] A support member 12 is connected to the side of the inner cavity of the chamber 1 near the powder cleaning seat 2. The surface of the support member 12 is covered with a grid plate 3, which is laid horizontally. This allows the floor of the chamber 1 to be leveled, ensuring that the floor is horizontal when the workpiece is powder sprayed. The grid plate 3 with holes ensures that the dust falls automatically to the powder collection surface 21 through the holes, ensuring the powder cleaning efficiency. It also prevents workpieces or large foreign objects from falling into the conveying pipe 22 and clogging it, which would affect subsequent powder cleaning and ensure the service life.

[0029] Reference Figures 3-4 , Figure 3 This is a schematic diagram of the powder suction component of this utility model; Figure 4 This utility model Figure 2 Enlarged schematic diagram of the structure at point A. A dust removal device for a powder spraying booth also includes a dust suction component 4. The dust suction component 4 is connected to one end of the conveying pipe 22 located at the center of the dust collection surface 21. The end of the dust suction component 4 away from the dust removal seat 2 has a turning part 41, and the turning part 41 turns the gas drawn by the conveying pipe 22 into a horizontal direction. This allows the vertical upward direction of the gas drawn by the conveying pipe 22 to be changed to a horizontal direction by blocking it, and the gas is drawn in a ring shape. This ensures that the dust can be drawn by the conveying pipe 22 after falling along the dust collection surface 21 to the center of the dust removal seat 2, without any dead corners in the dust removal process.

[0030] The powder suction component 4 has a mounting part 42 at one end near the conveying pipe 22, and the mounting part 42 has a through hole in the middle to connect the conveying pipe 22 with the outside. This ensures that the powder suction component 4 will not block the conveying pipe 22 after it is installed in the center of the powder cleaning seat 2, and also ensures the turning ability of the turning part 41 to turn the extracted gas. The powder suction component 4 has a connecting part 43 in the middle, and the connecting part 43 is in the shape of a vertical plate, so that the turning part 41 and the mounting part 42 can be connected to ensure that the powder suction component 4 is a whole.

[0031] The connecting part 43 is thin and twisted at a certain angle, so that when the gas is extracted, the flowing air can impact the connecting part 43, and under the action of the connecting part 43 twisting at a certain angle, the connecting part 43 rotates, thereby causing the dust suction component 4 to rotate as a whole. Then, under the action of centrifugal force, the dust falling on the upper surface of the turning part 41 is thrown onto the dust collection surface 21, thereby further ensuring that there are no dead corners in the dust removal.

[0032] The side of the turning part 41 away from the mounting part 42 is conical, which allows dust falling on the surface of the turning part 41 to slide off along the turning part 41 even when it encounters a small centrifugal force, thus improving the dust removal quality.

[0033] A bearing is provided at the connection between the mounting part 42 and the conveying pipe 22, which reduces the friction that the powder suction part 4 needs to overcome to rotate and improves the rotation efficiency.

[0034] The grid plates 3 are multiple and arranged side by side, so that when it is necessary to replace or maintain the powder suction component 4, the powder collection surface 21 and the conveying pipe 22, one grid plate 3 can be removed for replacement and maintenance.
