Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and in particular to a dust removal device for powder coating processing. Background Technology

[0002] Powder coating processing involves mixing various raw materials in a mixing device, then melting, shearing, and dispersing the mixture using a melt extruder. After cooling and pressing into sheets, the mixture is crushed, ground into powder using an air jet mill, and then the particle size is controlled by cyclone separation and sieving. Qualified powder is collected, packaged, and inspected. During the process of pouring the powder raw materials into the coating processing equipment, some powder will be scattered in the air. It is necessary to install a dust removal device next to the coating processing equipment to absorb the scattered powder and prevent it from being inhaled by the operators, thus affecting their health.

[0003] When the opening of the coating processing equipment is large and the suction port of the dust removal device is small, excessive suction will suck in the powder that has not yet dispersed, resulting in waste. Insufficient suction will not be able to completely remove the dispersed powder, affecting the dust removal effect. Therefore, this application provides a dust removal device for powder coating processing to meet the needs. Utility Model Content

[0004] This utility model provides a dust removal device for powder coating processing to solve the problems of waste caused by excessive suction force and insufficient suction force affecting dust removal effect.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A dust removal device for powder coating processing includes a suction dust collector and a suction pipe, wherein the suction pipe is installed at the air inlet of the suction dust collector, and further includes:

[0007] The shielding mechanism includes two splicing plates, which together form a cover to shield the feed inlet of the powder coating processing equipment. The splicing joint of the two splicing plates is provided with a feed inlet and a suction inlet, and a suction pipe is installed inside the suction inlet.

[0008] Preferably, a splicing funnel is fixed at the feed inlet of the splicing plate, and two splicing funnels form a feed hopper.

[0009] Preferably, a semi-circular ring is fixed at the suction port of the splicing plate, and the two semi-circular rings are attached to the surface of the suction tube and fixed by bolts.

[0010] Preferably, the splicing panel is hollow.

[0011] Preferably, the bottom of the splicing plate is provided with a slope, which is used to guide the scattered material to flow towards the suction port.

[0012] Preferably, the bottom of the splicing plate is fixed with a splicing baffle. The two splicing baffles are inclined and the inclination direction of the two splicing baffles is opposite to the inclination direction of the inclined plane. The two splicing baffles form a V shape and are used to block the material falling from the feed port from flowing to the suction port.

[0013] Preferably, the surface of the splicing baffle is fixed with a number of protrusions, which are arranged vertically.

[0014] Preferably, the side of the splicing plate is integrally formed with a ring, and the bottom of the ring is fixed with a splicing L-shaped sealing ring. The side of the splicing L-shaped sealing ring is fixed to the side of the splicing plate. The vertical part of the L-shaped sealing ring is curved, and the inside of the L-shaped sealing ring has a cavity. In use, the horizontal part of the L-shaped sealing ring contacts the top of the opening of the powder coating processing equipment, and the vertical part of the L-shaped sealing ring contacts the inner wall of the powder coating processing equipment.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, by setting up splicing plates, two splicing plates are combined into a cover during use. The splicing plates are connected by splicing to avoid the large suction head at the end of the suction pipe. The cover covers the opening of the paint processing equipment. The material is poured into the paint processing equipment from the feed inlet. The cover blocks the scattered powder, preventing the powder from scattering out of the paint processing equipment. At this time, the suction dust collector is started. The suction dust collector can absorb and remove the scattered powder with a small suction force, which can not only avoid the waste of powder, but also ensure the dust removal effect.

[0017] By setting up an inclined plane, the drifting powder can be guided, making it easier for the drifting powder to enter the suction pipe from the suction port, thus ensuring the dust removal effect.

[0018] By setting up splicing baffles, the feed inlet and suction outlet are separated, preventing suction from affecting the material discharge. Secondly, the inclined splicing baffles can guide the airflow, preventing the splicing baffles from directly blocking the scattered powder from entering the suction outlet, thus ensuring the dust removal effect.

[0019] By setting up L-shaped sealing rings, the sealing between the splicing plate and the coating processing equipment can be improved, preventing powder from drifting out from the gaps and ensuring the effectiveness of dust extraction.

[0020] By setting a cavity, when the top of the coating processing equipment presses against the horizontal part of the L-shaped sealing ring, the gas in the cavity of the horizontal part of the L-shaped sealing ring will be squeezed into the cavity of the vertical part of the L-shaped sealing ring. At this time, the vertical part of the L-shaped sealing ring will expand outward and fit against the inner wall of the coating processing equipment, thereby further improving the sealing performance. The vertical part of the L-shaped sealing ring is set with a curved surface, and the bottom of the curved surface is far away from the inner wall of the coating processing equipment, which makes it easy for the L-shaped sealing ring to be inserted into the coating processing equipment and avoids jamming between the L-shaped sealing ring and the coating processing equipment.

[0026] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of this utility model.

Detailed Implementation

[0027] The dust removal device for powder coating processing provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can also use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0028] like Figures 1-4As shown in the figure, an embodiment of the present invention provides a dust removal device for powder coating processing, including a suction dust collector 1 and a suction pipe 2. The suction pipe 2 is installed at the air inlet of the suction dust collector 1, and further includes:

[0029] The shielding mechanism 3 includes two splicing plates 4, which together form a cover to shield the feed inlet of the powder coating processing equipment. A feed inlet 8 and a suction inlet 9 are located at the joint of the two splicing plates 4. A suction pipe 2 is installed inside the suction inlet 9. The suction dust collector 1 generates negative pressure through the suction pipe 2. The cover formed by the two splicing plates 4 can completely cover the feed inlet of the processing equipment, confining the dust generated when the powder coating is poured into a closed space, preventing dust from spreading to the workshop environment, and significantly reducing the risk of operators inhaling dust. The feed inlet 8 is used for material input, and the suction inlet 9 is connected to the suction pipe 2. The connection allows dust in the enclosed space to be sucked into the dust collector 1, reducing powder waste and preventing dust from adhering to the equipment surface and increasing cleaning costs. The two splicing plates 4 are fixedly connected by bolts. At the bottom of the suction pipe 2, there is a suction head with a diameter larger than that of the suction pipe 2. The splicing plates 4 adopt a splicing connection to avoid the suction head. The splicing plates 4 do not need to be disassembled before installation and removal of the suction head, making the installation and removal of the splicing plates 4 more convenient. The splicing design also makes it easy to adjust the specifications of the splicing plates 4 according to different sizes of powder coating processing equipment, with strong adaptability. At the same time, it is easy to disassemble and does not affect the daily maintenance of the equipment.

[0030] like Figure 1 As shown in this embodiment, a splicing funnel 5 is fixed at the feed inlet 8 of the splicing plate 4. The two splicing funnels 5 form a feed hopper. The feed hopper formed by the two splicing funnels 5 is inverted cone shape, which can guide the powder coating to fall into the feed inlet of the processing equipment, avoid the material from spilling on the surface of the cover when it is poured, and further reduce dust generation.

[0031] like Figure 1 As shown in this embodiment, a semi-circular ring 12 is fixed at the suction port 9 of the splicing plate 4. The two semi-circular rings 12 are attached to the surface of the suction pipe 2 and fixed by bolts. The two semi-circular rings 12 are clamped by bolts and can be tightly attached to the surface of the suction pipe 2 to form a sealed connection, preventing dust from leaking from the gap between the suction port 9 and the suction pipe 2, and ensuring dust collection efficiency.

[0032] like Figure 3 and Figure 4 As shown in this embodiment, the splicing plate 4 is hollow. The hollow structure can significantly reduce the weight of the splicing plate 4, making it easier for operators to handle, assemble and disassemble, and reducing labor intensity.

[0033] like Figure 2As shown in this embodiment, the bottom of the splicing plate 4 is provided with a slope 13. The slope 13 is used to guide the scattered material to flow towards the suction port 9. The slope 13 guides the scattered dust towards the suction port 9, further improving the dust removal effect.

[0034] like Figure 2 As shown in this embodiment, a splicing baffle 6 is fixed to the bottom of the splicing plate 4. The two splicing baffles 6 are set at an angle, and the angle of the two splicing baffles 6 is opposite to the angle of the inclined surface 13. The two splicing baffles 6 form a V shape. The two splicing baffles 6 are used to block the material falling from the feed inlet 8 from flowing to the suction port 9. The V-shaped splicing baffles 6 can form a barrier between the feed inlet 8 and the suction port 9, effectively preventing the normally falling powder coating from being sucked into the suction pipe 2, avoiding material waste. The angle of the baffle is opposite to that of the inclined surface 13, so it can block the material without hindering the drifting dust from flowing along the inclined surface 13 to the suction port 9.

[0035] like Figure 2 As shown in this embodiment, the surface of the splicing baffle 6 is fixed with several protrusions 7. The several protrusions 7 are arranged vertically. The vertical protrusions 7 can further prevent the powder from being sucked into the suction pipe 2, while not affecting the airflow. The protrusions 7 can also disrupt the airflow direction, causing the scattered dust to form a temporary retention on the surface of the baffle, causing the powder to fall back into the equipment and improving the powder utilization rate.

[0036] like Figure 4 As shown in this embodiment, a circular ring is integrally formed on the side of the splicing plate 4, and a splicing L-shaped sealing ring 10 is fixed to the bottom of the circular ring. The side of the splicing L-shaped sealing ring 10 is fixed to the side of the splicing plate 4. The vertical part of the L-shaped sealing ring is curved, and a cavity 11 is opened inside the L-shaped sealing ring. In use, the horizontal part of the L-shaped sealing ring contacts the top of the opening of the powder coating processing equipment, and the vertical part of the L-shaped sealing ring contacts the inner wall of the powder coating processing equipment. The splicing L-shaped sealing ring 10 is made of highly elastic rubber material, which can fill the gap between the splicing plate 4 and the processing equipment, prevent dust from leaking from the gap, and ensure the sealing effect. The horizontal part contacts the top of the equipment, while the vertical part contacts the inner wall of the equipment, forming a "double seal" for a more comprehensive seal. The curved design of the vertical part guides the sealing ring to smoothly insert into the equipment, avoiding hard contact with the inner wall that could cause jamming or damage. At the same time, the curved surface increases the contact area with the inner wall, improving the sealing effect. The internal cavity 11 has elastic deformation capability. When the top of the equipment presses against the horizontal part, the gas in the cavity 11 flows towards the vertical part, causing the vertical part to expand outward and further conform to the inner wall of the equipment, compensating for minor unevenness of the inner wall and resulting in a better sealing effect. The splicing design is assembled synchronously with the splicing plate 4, eliminating the need for additional sealing steps and making operation convenient.

[0037] Working principle: Two splicing plates 4 are spliced ​​together to form a cover, aligning the feed inlet 8 and suction inlet 9 at the splicing point. One end of the suction pipe 2 is installed at the air inlet of the suction dust collector 1, and the other end is placed between the semicircular rings 12 at the suction inlets 9 of the two splicing plates 4. The two semicircular rings 12 are fixed with bolts so that the semicircular rings 12 fit against the surface of the suction pipe 2. At the same time, the splicing funnels 5 at the feed inlets 8 of the two splicing plates 4 form a feed hopper, and the splicing baffle 6 at the bottom forms a V-shape, and the inclination direction of the splicing baffle 6 is opposite to the inclination direction of the bottom slope 13 of the splicing plate 4.

[0038] The assembled cover is placed over the feed inlet of the powder coating processing equipment, so that the L-shaped sealing ring 10 at the bottom of the side ring of the splicing plate 4 fits the equipment. The horizontal part of the L-shaped sealing ring 10 contacts the top of the equipment opening, and the vertical part is inserted into the equipment and contacts the inner wall. When the top of the equipment presses the horizontal part of the L-shaped sealing ring 10, the gas in the cavity 11 of the horizontal part of the L-shaped sealing ring 10 is squeezed into the cavity 11 of the vertical part of the L-shaped sealing ring 10, causing the vertical part of the L-shaped sealing ring 10 to expand outward, further improving the sealing performance.

[0039] Start the suction dust collector 1 and pour the powder coating into the feed hopper composed of spliced ​​funnels 5. The material enters the processing equipment through the feed inlet 8. During the process, some of the scattered powder is blocked by the cover and flows towards the suction port 9 under the guidance of the bottom slope 13 of the spliced ​​plate 4. The spliced ​​baffle 6 blocks the material from flowing to the suction port 9 and guides the airflow. The protrusion 7 is used to block the powder from continuing to flow to the suction port 9. The suction dust collector 1 sucks in the scattered powder from the suction port 9 through the suction pipe 2 to complete the dust removal.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
