Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a device for removing VOC from PC / ABS modified materials and drying the materials. Background Art

[0002] Low-odor PC / ABS material is a mixture of polycarbonate (PC) and acrylonitrile-butadiene-styrene copolymer (ABS) in a certain proportion. This mixed material not only has the high strength, high heat resistance, excellent impact resistance and UV resistance of PC, but also has the good processability, surface gloss and easy coloring of ABS. It is widely used to manufacture various interior parts, such as dashboards, center consoles, door panels, seat backs, etc. It can not only improve the strength and durability of these parts, but also enhance the aesthetics of the interior. However, since PC / ABS modified materials contain volatile organic compounds (VOCs), long-term exposure to VOCs may lead to lung cancer, leukemia, miscarriage, fetal malformation and growth retardation. Therefore, the volatile organic compounds contained in the granular PC / ABS modified materials must be heat-dried to remove them before use. The existing technology has the following problems:

[0003] Chinese patent document CN215849087U discloses a drying device for removing VOCs from modified PC / ABS materials. The device comprises a housing with a ceiling mounted on top, a driven placement layer mounted on the ceiling via an upper driven spring, and a fixing block, with the ends of the upper driven spring fixed to the ceiling and the driven placement layer via the fixing blocks. The purpose of this utility model is to provide a drying device that shakes and flips the material during heating to accelerate the volatilization of volatile substances.

[0004] Although the above-mentioned literature can oscillate while heating to achieve rapid volatilization, the passive placement layer and the active placement layer used to place the PC / ABS modified material particles cannot be removed, and the entire box can only be taken out by opening the door. As a result, it is inconvenient to unload the PC / ABS modified material that has been dried. It can only be collected slowly by manually reaching into the box. Not only is the speed slow and affects the next drying, but there may also be omissions and incomplete collection, resulting in certain waste. Utility Model Content

[0027] By starting the motor 142, the turntable 143 can be driven to rotate, thereby pulling the movable connecting rod 144 to move upward, thereby coordinating the movable connecting rod 144 with the movable connection of the pull rod 145, pulling the three tapered plugs 146 upward, and under the action of the limit plate 147 against the bottom of the charging funnel 12, the entire charging funnel 12 is driven upward, and the PC / ABS modified material particles are transported to the inner cavity of the drying tank 1 through the feeding pipe 3, and are guided and concentrated into the uppermost charging funnel 12 through the guide funnel 11. At this time, the charging funnel 12 is blocked by the tapered plug 146 and will not fall until it spreads to the discharge chute 121. The particles fall into the middle loading funnel 12, and then the discharge chute 121 opened in the middle loading funnel 12 is used to make the particles fall into the lower loading funnel 12, so that all three loading funnels 12 are filled with PC / ABS modified material particles. When discharging, the rotation of the turntable 143 can be stopped, and then the electric push rod 14 is started, and the T-shaped top plate 141 is used to drive the overall motor 142, the turntable 143, and the pull rod 145 to descend, so that the three conical plugs 146 and the limit plate 147 are lowered, and the seal on the bottom of the three loading funnels 12 is released, so that all the baked PC / ABS modified material particles fall out of the loading funnel 12 and are discharged.

[0028] like Figure 4 As shown, extension plates 122 are fixedly installed on the left and right sides of the three charging funnels 12, and compression springs 123 are fixedly installed on the tops of the extension plates 122.

[0029] The compression springs 123 on the top of the extension plates 122 on the left and right sides of the charging funnel 12 are connected to the fixed plate 15 for compression, so that under the rotation of the turntable 143, the extension plates 122 are driven to repeatedly squeeze and release the fixed plate 15, and bounce up and down reciprocatingly to achieve an oscillating effect.

[0030] like Figure 5 As shown, a discharging motor 21 is fixedly installed on the right side of the discharging base 2, and a discharging channel 22 is opened on the discharging base 2. The inner cavity of the discharging channel 22 is interconnected with the inner cavity of the drying tank 1. A discharging pipe 24 is fixedly connected to the left side of the discharging base 2.

[0031] The baked PC / ABS modified material particles pass through the discharge funnel 13 and are concentrated into the inner cavity of the discharge channel 22 opened in the discharge base 2. Then, the discharge motor 21 is started to drive the screw rod 23 in the discharge channel 22 to rotate, and the sealing cover 25 on the right side of the discharge pipe 24 is rotated to open, so that the PC / ABS modified material particles can be discharged through the discharge pipe 24, completing the discharge.

[0032] like Figure 6 、 Figure 7 As shown, a heater 16 is fixedly installed on the rear side of the drying tank 1, and an air outlet end of the heater 16 passes through the inner cavity of the drying tank 1. The air outlet mechanism 4 includes an L-shaped exhaust pipe 41. The vertical part of the L-shaped exhaust pipe 41 is fixedly connected to the top right side of the drying tank 1, and the horizontal part of the L-shaped exhaust pipe 41 is fixedly connected to a connecting box 42 on the right side. A fan 43 is fixedly installed on the top of the connecting box 42. An exhaust hose 44 is fixedly connected to the right side of the fan 43. The other end of the exhaust hose 44 is fixedly connected to a threaded ring 45. A limiting ring 46 is fixedly installed on the side of the outer wall of the threaded ring 45 close to the exhaust hose 44. The side of the outer wall of the exhaust hose 44 away from the limiting ring 46 is threadedly connected to the right side of the inner wall of the connecting box 42. An activated carbon adsorption cylinder 47 is fixedly connected to the left side of the threaded ring 45, and an L-shaped exhaust pipe 48 is fixedly connected to the left side of the fan 43.

[0033] Under the vibration of the charging funnel 12, the PC / ABS modified material particles in the charging funnel 12 are evenly contacted with the hot air input by the heater 16 in the drying tank 1, so that the VOC contained in the PC / ABS modified material particles is volatilized. Then, by starting the fan 43 on the top of the connecting box 42, the exhaust hose 44, the connecting box 42, and the L-shaped exhaust pipe 41 can be used to extract the gas containing VOC from the inner cavity of the drying tank 1, and the gas is adsorbed and filtered through the activated carbon adsorption cylinder 47, and then the clean air is discharged through the L-shaped exhaust pipe 48. When the activated carbon adsorption cylinder 47 needs to be cleaned, it is only necessary to rotate the limit ring 46 to rotate the threaded ring 45 threadedly connected to the inner wall of the connecting box 42 together with the activated carbon adsorption cylinder 47 to take out for cleaning.

[0034] The following is a detailed description of the working principle of the PC / ABS modified material VOC removal drying device.

[0035] like Figure 1-7As shown, by starting the motor 142, the turntable 143 can be driven to rotate, thereby pulling the movable connecting rod 144 to move upward, thereby cooperating with the movable connection between the movable connecting rod 144 and the pull rod 145 to pull the three tapered plugs 146 upward, and under the action of the limit plate 147 against the bottom of the charging funnel 12, the entire charging funnel 12 is driven upward, and the compression springs 123 on the top of the extension plates 122 on the left and right sides of the charging funnel 12 are connected with the fixed plate 15 for compression, so that under the rotation of the turntable 143, the extension plates 122 are driven to repeatedly squeeze and release the fixed plate 15, and bounce up and down reciprocatingly, which has an oscillating effect, and at the same time, the P The PC / ABS modified material particles are transported to the inner cavity of the drying tank 1 by the feed pipe 3, and are guided by the guide funnel 11 to be concentrated into the uppermost charging funnel 12. At this time, the charging funnel 12 is blocked by the conical plug 146 and will not fall until it spreads to the discharge trough 121. The particles will fall into the middle charging funnel 12, and then the discharge trough 121 opened by the middle charging funnel 12 will make the particles fall into the lower charging funnel 12, so that all three charging funnels 12 are filled with PC / ABS modified material particles. Then, under the vibration of the charging funnel 12, the PC / ABS modified material particles are evenly mixed with the drying material in the charging funnel 12. The hot air input from the heater 16 in the tank 1 comes into contact with the VOC contained in the PC / ABS modified material particles, thereby volatilizing the VOC contained in the PC / ABS modified material particles. Then, by starting the fan 43 on the top of the connecting box 42, the exhaust hose 44, the connecting box 42, and the L-shaped exhaust pipe 41 can be used to extract the gas containing VOC from the inner cavity of the drying tank 1, and pass it through the activated carbon adsorption cylinder 47 for adsorption and filtration, and then the clean air is discharged through the L-shaped exhaust pipe 48. When the activated carbon adsorption cylinder 47 needs to be cleaned, it is only necessary to rotate the limit ring 46 to rotate the threaded ring 45 threadedly connected to the inner wall of the connecting box 42 together with the activated carbon adsorption cylinder 47 to take it out for cleaning. The turntable 1 can be stopped when discharging. 43 rotates, and then starts the electric push rod 14, and uses the T-shaped top plate 141 to drive the overall motor 142, the turntable 143, and the pull rod 145 to descend, so that the three conical plugs 146 and the limit plate 147 descend, and the seal on the bottom of the three charging funnels 12 is released, so that the baked PC / ABS modified material particles pass through the discharging funnel 13 and enter the inner cavity of the discharging channel 22 opened in the discharging base 2, and then start the discharging motor 21 to drive the screw rod 23 in the discharging channel 22 to rotate, and rotate to open the sealing cover 25 on the right side of the discharging pipe 24, so that the PC / ABS modified material particles can be discharged through the discharging pipe 24, and the discharging is completed.

[0036] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are intended to be within the scope of protection of the present invention.
