Technical Field
[0001] This application relates to the field of paint production technology, and in particular to a paint exhaust gas collection device. Background Technology
[0002] Paint is a chemical mixture that can firmly cover the surface of an object, serving as a protective, decorative, marking, and other special-purpose coating. The paint production process mainly includes six core steps: batching, dispersion, grinding, paint mixing, filtration, and packaging, involving raw material selection, physical mixing, and chemical processing.
[0003] In related technologies, paint will generate a large amount of volatile organic compounds (VOCs) during the mixing and blending process. These gases not only pollute the environment but also harm human health. Utility Model Content
[0004] The purpose of this application is to address the aforementioned problems in the prior art by proposing a paint exhaust gas collection device.
[0005] This application can be achieved through the following technical solution: a paint exhaust gas collection device, including a gas collection hood installed above the processing barrel, an exhaust gas discharge pipe connected to the gas collection hood, and an exhaust fan installed in the exhaust gas discharge pipe. The gas collection hood is provided with baffles around its perimeter, and the baffles are arranged around the processing barrel.
[0006] In the above technical solution, the exhaust gas generated during the paint mixing process can be drawn away to another place by the exhaust fan through the gas collection hood and exhaust pipe. If splashing occurs during the paint mixing process, the baffle can prevent the splashed paint from splashing onto the workshop floor.
[0007] Furthermore, several outer retaining rings and several inner retaining rings are installed on the outer wall of the gas collecting hood. The outer retaining rings and several inner retaining rings are arranged around the axis of the gas collecting hood. The baffle is composed of several inner baffles and several outer baffles, which are overlapped. A through rod is inserted through both the inner baffles and the outer baffles. The outer retaining rings or inner retaining rings are used to engage the through rods.
[0008] In the above technical solution, the inserting rod is inserted into the inner or outer baffle, and then the inserting rod is snapped into the elastic retaining ring. The inner and outer baffles are then installed. The adjacent inner and outer baffles have overlapping areas, which allows the exhaust gas to be better collected at the position directly below the gas collection hood.
[0009] Furthermore, a magnet 1 and a magnet 2 are respectively installed on each of the two length sides of the inner baffle and the outer baffle, and the magnet 1 can attract the magnet 2.
[0010] In the above technical solution, magnet one can attract magnet two, which can further improve the collection effect of exhaust gas under the gas collection hood.
[0011] Furthermore, the gas collection hood includes a housing connected to the exhaust pipe, a mounting ring surrounding the housing, and a telescopic sleeve rod located at the top of the housing. The mounting ring is installed on the telescopic end of the telescopic sleeve rod, and the inner sidewall of the mounting ring can abut against the outer sidewall of the housing. Both the outer retaining ring and the inner retaining ring are located on the mounting ring.
[0012] In the above technical solution, when the lowest point of the inner baffle and the outer baffle is lower than the upper point of the processing barrel, the processing barrel is directly pushed horizontally to move it away from directly below the gas collection hood. The paint on the inner wall of the processing barrel is easy to stick to the inner baffle or the outer baffle. By setting the mounting ring, when it is necessary to move the processing barrel away from below the gas collection hood, first manually lift the mounting ring upward so that the lowest point of the inner baffle and the outer baffle is higher than the processing barrel, and then move the processing barrel away from below the gas collection hood.
[0013] Furthermore, both the outer and inner retaining rings are attached to the gas collection hood using tear-off adhesive.
[0014] In the above technical solution, when the outer or inner retaining ring breaks, the adhesive can be peeled off to facilitate the disassembly and replacement of the outer and inner retaining rings.
[0015] Furthermore, it also includes a baffle ring installed on the mounting ring, on which multiple suction pipes are installed, the suction pipes being used to draw out exhaust gas between the inner baffle, the outer baffle, and the mounting ring.
[0016] In the above technical solution, since the inner baffle and the outer baffle are stacked, there will be gaps between the outer baffle and its two adjacent inner baffles and the mounting ring during installation. By setting a baffle ring, the exhaust pipe installed on the baffle ring can remove the exhaust gas in the gaps between the two inner baffles, the outer baffle and the mounting ring, further reducing the probability of exhaust gas overflow.
[0017] Furthermore, the through rod includes a rod body that passes through the inner or outer baffle and two limiting blocks that are correspondingly located at both ends of the rod body along its length, with the inner or outer baffle located between the two limiting blocks.
[0018] In the above technical solution, the limiting block can limit the inner and outer baffles to prevent the inner or outer baffles from detaching from the rod.
[0019] Furthermore, the limiting block is threadedly connected to the rod body.
[0020] In the above technical solution, the limiting block is threadedly connected to the rod body, which facilitates the installation of the limiting block.
[0021] In summary, this application has the following technical effects: the exhaust gas generated during the paint mixing process can be drawn away to another location by the exhaust fan through the gas collection hood and exhaust pipe; if splashing occurs during the paint mixing process, the baffle can prevent the splashed paint from easily splashing onto the workshop floor.

Evacuation pipe; Detailed Implementation
[0026] Reference Figure 1 One embodiment of this application provides a paint exhaust gas collection device, including a gas collection hood 1 disposed above a processing bucket. The gas collection hood 1 includes a housing 11 and an mounting ring 12 surrounding the housing 11. The housing 11 is connected to an exhaust gas discharge pipe 2, and an exhaust fan 3 is installed inside the exhaust gas discharge pipe 2. The housing 11 can collect exhaust gas, and the exhaust fan 3 can suck the exhaust gas generated by the paint in the processing bucket to another location through the housing 11. Three telescopic sleeves 13 are installed at the top of the housing 11, and the three telescopic sleeves 13 are arranged around the axis of the housing 11. The telescopic ends of the telescopic sleeves 13 are equipped with mounting rings 12. The cross-section of the mounting rings 12 is right-angled, and the inner sidewall of the mounting rings 12 can abut against the vertical outer sidewall of the housing 11.
[0027] Reference Figure 1 , 2Several outer retaining rings 5 and several inner retaining rings 6 are installed on the outer wall of the mounting ring 12. The outer retaining rings 5 and several inner retaining rings 6 are all arranged around the axis of the cover 11. The outer retaining rings 5 and the inner retaining rings 6 are made of elastic material. The outer retaining rings 5 and the inner retaining rings 6 are alternately arranged. The outer retaining rings 5 and the inner retaining rings 6 are both attached to the mounting ring 12 with peelable adhesive. The outer retaining rings 5 and the inner retaining rings 6 each include a mounting block and a snap ring formed on the mounting block. The mounting block is attached to the mounting ring 12 with peelable adhesive. The mounting block of the outer retaining ring 5 is longer than the mounting block of the inner retaining ring 6. The peelable adhesive can be nano-residue-free double-sided tape that can be purchased directly. A baffle 4 is provided around the mounting ring 12. The baffle 4 is arranged around the processing barrel. The baffle 4 includes several inner baffles 41 and several outer baffles 42. The several inner baffles 41 and several outer baffles 42 are all arranged around the axis of the mounting ring 12. The outer baffles 42 are located on the side of the inner baffles 41 away from the axis of the cover 11. Both the inner baffle 41 and the outer baffle 42 are elongated strips. A through rod 7 is provided at the top of both the inner baffle 41 and the outer baffle 42. The through rod 7 includes a rod body 71 that passes through the top of the inner baffle 41 or the outer baffle 42 and two limiting blocks 72 that are threadedly connected to the rod body 71. A locking ring is used to lock the rod body 71 in place. The two limiting blocks 72 are threadedly connected to the two ends of the rod body 71 in the length direction. The limiting blocks 72 can limit the movement of the inner baffle 41 or the outer baffle 42 to prevent the inner baffle 41 or the outer baffle 42 from detaching from the rod body 71. The inner baffle 41 and the outer baffle 42 can slide up and down with the mounting ring 12.
[0028] When the lowest point of the inner baffle 41 and the outer baffle 42 is lower than the upper point of the processing barrel, the processing barrel is directly pushed horizontally to move it away from directly below the gas collection hood 1. The paint on the inner wall of the processing barrel is easy to stick to the inner baffle 41 or the outer baffle 42. By setting the mounting ring 12, when it is necessary to move the processing barrel away from below the gas collection hood 1, first manually lift the mounting ring 12 upward so that the lowest point of the inner baffle 41 and the outer baffle 42 is higher than the processing barrel, and then move the processing barrel away from below the gas collection hood 1.
[0029] Reference Figure 1 , 2A magnet 8 and a magnet 9 are installed on each of the two length sides of the inner baffle 41 and the outer baffle 42 respectively. Magnet 8 can attract magnet 9. Both magnet 8 and magnet 9 can be rubber magnets, thereby reducing the possibility of exhaust gas overflowing from between the inner baffle 41 and the outer baffle 42. A baffle ring 10 is also installed at the top of the mounting ring 12. The baffle ring 10 has a right-angle cross-section. The top surface of the inner wall of the baffle ring 10 can abut against the top of the outer baffle 42. The vertical inner wall of the baffle ring 10 can abut against the surface of the outer baffle 42 away from the cover 11. Since the inner baffle 41 and the outer baffle 42 are overlapped, there is a gap between the outer baffle 42 and its two adjacent inner baffles 41 and the mounting ring 12 during installation. Multiple exhaust pipes 14 are installed on the baffle ring 10. An exhaust fan is connected to the exhaust pipe 14. The exhaust pipe can draw the exhaust gas generated in the gap between the two inner baffles 41, the outer baffle 42 and the mounting ring 12 to another place.
[0030] The working principle of this embodiment is as follows: the exhaust gas generated during the paint mixing process can be drawn away to another place by the exhaust fan 3 through the gas collection hood 1 and the exhaust pipe 2. If splashing occurs during the paint mixing process, the baffle 4 can prevent the splashed paint from splashing onto the workshop floor.
[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
