Description

Technical Field

[0001] This utility model relates to the field of polyurea spraying technology, and in particular to a waste collection device for polyurea spraying. Background Technology

[0002] Polyurea is an elastomer material formed by the reaction of isocyanate components and amino compound components. It has a high melting point, high toughness, and good heat resistance, dyeability, and corrosion resistance. It is widely used in many fields. After spraying a single-component polyurea onto the surface of parts, it can effectively improve the performance of the parts in various aspects. The spraying is carried out by spray gun or disc atomizer, which disperses the polyurea into uniform and fine droplets with the help of pressure or centrifugal force. The coating method can be divided into air spraying, airless spraying, electrostatic spraying, and various derivatives of the above basic spraying forms. During the workpiece processing, a protective layer or color layer is formed by spraying.

[0003] During the polyurea spraying process, a large amount of dust is often generated. Usually, pads or dust covers are used to prevent the paint from contaminating the spraying environment. However, there is still a lot of dust in the air that pollutes the environment and seriously affects the health of operators. Therefore, it is necessary to collect and treat the dust. Summary of the Invention

[0004] In view of this, the present invention provides a waste collection device for polyurea spraying to solve the above-mentioned technical problems.

[0005] A waste collection device for polyurea spraying includes a first box and a second box connected to the first box. Both the first and second boxes are rectangular box-shaped structures with openings at both ends, and are connected and abut against each other at the open ends. The first box includes a first housing, a fixing strip around the first housing, an adsorption section inside the first box, and two air inlets between the first housing and the adsorption section. The adsorption section is a rectangular box inside the first housing, open on one side with the opening direction aligned with the axial direction of the first housing, and the opening of the adsorption section faces away from the end of the first housing where the fixing strip is located. The sidewall of the adsorption section abuts against two opposite sidewalls of the first housing and is spaced apart from the other two opposite sidewalls. The length of the adsorption section in the air inlet direction is the same as the length of the sidewall of the first housing in the air inlet direction. The air inlets are located between the adsorption section and the first housing. The second box includes a second housing, two ventilation sections inside the second housing, and an air outlet between the two ventilation sections. Each of the ventilation sections includes a baffle and an inclined plate connected to the baffle. The baffle is disposed at an opening in the second housing away from the first housing. The position of the baffle corresponds to the position of the air inlet. One end of the inclined plate is connected to the baffle connection, and the other end extends toward the adsorption section, and the distance from the end of the inclined plate connected to the baffle to the second housing is greater than the distance from the free end extending toward the adsorption section to the second housing.

[0006] Furthermore, the first and second boxes have the same area of ​​rectangular structure in cross-section along the opening direction.

[0007] Furthermore, the connection between the first box and the second box is made by means of a connecting latch, a fastener, or a pin.

[0008] Furthermore, the fixing strip is vertically disposed on the first housing and along one of the openings of the first housing, and extends in a direction away from the center of the first housing.

[0009] Furthermore, the fixing strip is integrally formed with the first housing.

[0010] Furthermore, the second housing has the same structure and dimensions as the first housing.

[0011] Furthermore, the shape and size of the baffle are consistent with the shape and size of the cross-section of the air intake.

[0012] Furthermore, a filter screen is also provided at the opening of the air outlet away from the first housing.

[0013] Compared with existing technologies, the waste collection device for polyurea spraying provided by this utility model, by setting up the adsorption section and the ventilation section, forms a tortuous gas flow channel when the device is placed on the air duct. When polyurea spraying waste is sucked in, the flow formed by the adsorption section and the ventilation section causes the spraying waste to be adsorbed on the surface of the flow channel and accumulated in the adsorption section, thereby realizing the collection of polyurea spraying waste. At the same time, the first shell and the second shell are spliced ​​together, which facilitates disassembly and cleaning of the waste inside. Attached Figure Description

[0017] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0018] like Figures 1 to 3 The diagram shows a structural schematic of the waste collection device for polyurea spraying provided by this utility model. The waste collection device for polyurea spraying includes a first housing 10 and a second housing 20 connected to the first housing 10. It is conceivable that the waste collection device for polyurea spraying also includes other functional modules such as an air outlet filter, a negative pressure fan, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0019] Both the first box 10 and the second box 20 are rectangular box-shaped structures with openings at both ends. They abut against each other and connect at the open ends to form a rectangular box-shaped structure with openings at both ends, used to collect spraying waste. Accordingly, the rectangular structures of the first box 10 and the second box 20 have the same area in cross-section along the opening direction. Furthermore, the connection between the first box 10 and the second box 20 can be made using connecting latches, snap-fit ​​fasteners, or other connecting components such as pins. This should be prior art known to those skilled in the art and is not the main content of this application; therefore, it is only briefly described here.

[0020] The first box body 10 includes a first shell 11, a fixing strip 12 arranged around the first shell 11, an adsorption part 13 arranged inside the first box body 10, and two air inlets 14 arranged between the first shell 11 and the adsorption part 13.

[0021] The first housing 11 may be made of materials such as PVC and bent into a rectangular box-shaped structure with openings at both ends to form the outer wall of the first box body 10.

[0022] The fixing strip 12 is vertically disposed on the first housing 11 and is disposed along one of the openings of the first housing 11, and extends in a direction away from the center of the first housing 11, and may be integrally formed with the first housing 11. In use, the first box 10 and the second box 20 are inserted into a chimney-shaped air duct, and the fixing strip 12 can abut against the edge of the air duct to fix and seal the gap.

[0023] The adsorption section 13 is a rectangular box disposed inside the first housing 11, with an opening on one side and the opening direction being consistent with the axial direction of the first housing 11. The opening of the adsorption section 13 faces away from the end of the first housing 11 where the fixing strip 12 is located. The sidewall of the adsorption section 13 abuts against two opposite sidewalls of the first housing 11 and is spaced apart from the other two opposite sidewalls, thereby forming two air inlets 14 on both sides of the adsorption section 13. The length of the adsorption section 13 in the air inlet direction is consistent with the length of the sidewall of the first housing 11 in the air inlet direction, so that the spraying waste sucked in by the air inlet 14 will not directly enter the adsorption section 13 from the air inlet 14.

[0024] The air intake 14 is located between the adsorption section 13 and the first housing 11, thereby forming an air duct for sucking up spraying waste residue.

[0025] The second housing 20 includes a second housing 21, two ventilation sections 22 disposed within the second housing 21, and an air outlet 23 located between the two ventilation sections 22.

[0026] The second housing 21 has the same structure and size as the first housing 11, so that the first housing 11 and the second housing 21 can be spliced ​​into a box-shaped structure when the device is in use.

[0027] Each of the ventilation sections 22 includes a baffle 221 and an inclined plate 222 connected to the baffle 221.

[0028] The baffle 221 is disposed at the opening of the second housing 21 away from the first housing 11. The shape and size of the baffle 221 are the same as the shape and size of the cross section of the air inlet 14, and the position of the baffle 221 corresponds to the position of the air inlet 14, so that the spraying waste entering from the air inlet 14 is blocked by the baffle 221.

[0029] One end of the inclined plate 222 is connected to the baffle 221, and the other end extends toward the adsorption part 13. The distance from the end of the inclined plate 222 connected to the baffle 221 to the second housing 21 is greater than the distance from the free end extending toward the adsorption part 13 to the second housing 21, thereby making the ventilation part 22 form an integral V-shaped structure.

[0030] The air outlet 23 is located between the two inclined plates 222 for gas flow. A filter screen or other filtration device may also be installed at the opening of the air outlet 23 away from the first housing 10 to filter waste at the outlet.

[0031] In use, the first box 10 and the second box 20 are spliced ​​together and inserted into a chimney-like air duct structure. The fixing strip 12 is clipped to the edge of the air duct. The air inlet 14 faces the workpiece to be sprayed with polyurea, and the air outlet 23 faces the suction device. During the spraying operation, the suction device continuously sucks in air, which causes a gas flow channel to be formed inside the device of this application. Suction is generated at the air inlet 14, which sucks in the dust-like waste material formed during polyurea spraying. Since the ventilation section 22 and the adsorption section 13 form a tortuous gas flow channel, a clump is formed inside the device. The waste material will clump together and be adsorbed in the adsorption section 13. Some waste material will be adsorbed in other parts of the gas flow channel, such as the air inlet 14 or the ventilation section 22. A small amount of waste material will be discharged from the air outlet 23.

[0032] Compared with the prior art, the waste collection device for polyurea spraying provided by this utility model, by setting the adsorption section 13 and the ventilation section 22, forms a tortuous gas flow channel when the device is placed on the air duct. When polyurea spraying waste is sucked in, the flow formed by the adsorption section 13 and the ventilation section 22 causes the spraying waste to be adsorbed on the surface of the flow channel and accumulated in the adsorption section 13, thereby realizing the collection of polyurea spraying waste. At the same time, the first shell 11 and the second shell 21 are spliced ​​together, which facilitates disassembly and cleaning of the internal waste.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
