Description

Technical Field

[0002] With the rapid development of modern industrial technology, spray powder processing technology and products are changing with each passing day. More and more spray powder products have been widely used in various fields of people's lives, bringing convenience to people. Spray powder is one of the most widely used decorative materials nowadays, with various colors. Spray powder spraying can not only increase the beauty of the product, but also play a protective role. Compared with paint, it has the advantages of low cost and good effect. A large amount of dust is easily generated during the production process of spray powder. The dust is discharged into the air and causes pollution to the environment. If inhaled, it will also cause damage to the human body. In order to reduce these hazards and increase the recycling rate and reduce production costs, a dust recovery device is needed.

[0003] The dust recovery equipment in the prior art usually uses an exhaust fan to extract the dust in the spray box, and then recycles it after simple filtration. However, during the spraying work, there is a situation where the floating dust is nodulated with each other, resulting in dust of different particle sizes. The direct use of dust of different particle sizes after unified collection will affect the quality of the next spraying. At the same time, dust will also adhere to the inner wall of the electrostatic spray box during recycling, causing waste. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0027] The electrostatic spraying cabinet 1 has a top opening 101, an electrostatic spraying device is provided on one side of the electrostatic spraying cabinet 1, and an exhaust fan 102 is provided on the other side, and the exhaust fan 102 is communicated with a dust recovery box.

[0028] like Figure 3 The filter assembly 2 shown includes an upper cover 201 and a filter group 202. The filter group 202 is fixed under the upper cover 201 and inserted from the opening 101 on the top of the electrostatic spray cabinet 1. The filter group 202 is composed of a plurality of longitudinal filters. The filter holes of the plurality of longitudinal filters have different diameters, and the filter hole diameter decreases from large to small in the direction from the electrostatic spray equipment to the exhaust fan 102.

[0029] The bottom of each filter in the filter group 202 is in close contact with the bottom of the inner cavity and the side walls of the electrostatic spraying cabinet top 1, so that the erosion dust on one side of the electrostatic spraying equipment is recovered and filtered under the action of the exhaust fan 102. After long-term use, the filter group 202 will inevitably leave different particles of dust on the surface of the filter group 202 and the bottom of the electrostatic spraying cabinet 1. In order to recover this part of the dust, a dust collection tank 103 with the same number of filters as the filter group 202 is set at the bottom of the inner cavity of the electrostatic spraying cabinet 1. Each filter is inserted into the corresponding dust collection tank 103 and is in close contact with the inner wall of the dust collection tank 103 on the side of the exhaust fan 102. In this way, dust of corresponding particle size falls into the corresponding dust collection tank 103 under the action of gravity. On this basis, a movable door 104 is set on the box wall of the electrostatic spraying cabinet 1, so that the dust in different dust collection tanks 103 can be recovered after opening. Example

[0030] In order to remove the dust attached to the electrostatic spraying cabinet 1, this embodiment provides a cleaning component 3 based on the embodiment 1, such as Figure 4 The embodiment shown in the figure includes a handle 301, a connecting arm 302, a wall brush 303 and a guide rod 304; the connecting arm 302 is two, each connecting arm 302 includes an L-shaped rod 3021 and a wall rod 3022, one end of the L-shaped rod 3021 is connected to the handle 301 and the other end is connected to the wall rod 3022, the L-shaped rod 3021 is mounted on the guide rod 304, the wall brush 303 is arranged on the wall rod 3022, and the wall brush 303 is in close contact with the inner wall of the electrostatic spraying cabinet top 1. In order to prevent the wall brush 303 from colliding with the electrostatic spraying equipment in a movable manner, the electrostatic spraying equipment and the workpiece to be sprayed extend into the electrostatic spraying cabinet 1 from one side of the movable door 104 and the opposite side thereof, so that the electrostatic spraying equipment, the workpiece to be sprayed and the wall brush are parallel to each other and do not interfere with each other.

[0031] As a supplement to the above embodiment, the handle 301 is rotatably connected to the two connecting arms 302, and a slot 1011 is provided on the side of the opening 101 for the handle 301 to extend out. The width of the filter group 202 is smaller than the width between the two connecting rods of the handle 301, so the insertion of the filter group 202 will not be affected by simply laying the handle 301 down. In order to prevent the dust inside the electrostatic spray cabinet top 1 from overflowing from the slot 1011, a pressing plate 2011 is provided at the bottom of the upper cover to match the handle 301 and the slot 1011, thereby ensuring the sealing between the opening 101, the handle 301, and the upper cover 201.

[0032] When cleaning is needed, take out the filter assembly 2, open the movable door 104 to recover the dust in each dust collection tank 103, turn the handle 301 vertically, and pull the handle 301. Driven by the connecting arm 302 and the guide rod 304, the wall brush 303 moves along the inner wall, thereby cleaning the inner walls on both sides of the electrostatic spray cabinet top 1. In order to ensure the stability of the cleaning assembly 3 when pulling the handle, a guide groove 3023 matching the guide rod 304 can be set under the L-shaped rod 3021.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
