Description

TECHNICAL FIELD

[0001] The application relates to the technical field of plastic recycling, in particular to a plastic waste recycling device for processing high-temperature-resistant materials. BACKGROUND

[0002] In the processing of high-temperature-resistant plastics such as phenolic resin, a large amount of waste containing conductor materials, insulating materials and other impurities will be generated. If these waste materials are directly discarded, not only will resources be wasted, but also the environment will be polluted. Therefore, how to efficiently recycle high-temperature-resistant plastic waste, especially to separate the conductor materials, insulating materials and phenolic resin, has become an important issue in the current plastic recycling field. Traditional plastic waste recycling methods mainly include mechanical separation, electrostatic separation and chemical treatment. However, these methods have the following problems when separating different components in high-temperature-resistant plastic waste: the conductor materials, insulating materials and phenolic resin in high-temperature-resistant plastic waste are usually mixed closely, and it is difficult to effectively separate them by using a screen or vibration separation, especially the separation effect of small particles is poor; conventional electrostatic separation technology has high requirements for the dielectric properties of materials, while the charge characteristics of phenolic resin, conductor and insulating material in high-temperature-resistant plastic waste are quite different, resulting in low separation precision and affecting the separation effect due to charge residues; some recycling methods use solvents to dissolve or chemically react to separate components, but the chemical resistance of phenolic resin is strong, ordinary solvents are difficult to separate efficiently, and may introduce secondary pollution. Therefore, it is urgent to develop an efficient and energy-saving high-temperature-resistant plastic waste recycling device that can accurately separate conductor materials, insulating materials and phenolic resin, and realize the rapid reforming of phenolic resin, so as to improve resource utilization and reduce environmental pollution.

Detailed Implementation

[0028] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0029] Example: Reference Figures 1-10 A recycling device for plastic waste used in the processing of high-temperature resistant materials includes a screening mechanism for separating conductor materials, phenolic resin and insulating materials in high-temperature resistant plastic waste. The screening mechanism includes a transformation box 101. The separation mechanism is equipped with a separation mechanism for separating phenolic resin that will become a soft solid. The separation mechanism is also equipped with a molding mechanism for remolding the separated phenolic resin. The screening mechanism includes an intermediate gear 108 and an upper bevel gear 107 rotatably mounted on the deterioration box 101; The separation mechanism includes a riser 219, on which four discharge pipes 203 are fixedly installed. A gear shaft 204 is rotatably installed on the uppermost discharge pipe 203, and an upper gear 205 and a lower gear 206 are fixedly installed on the gear shaft 204.

[0030] like Figures 2-4 As shown, the screening mechanism also includes a conductive support 102 fixedly installed on the deterioration box 101. A rotating drum 103 is rotatably installed on the conductive support 102. A rotating drum gear 104 is fixedly installed on the rotating drum 103. A side bevel gear 106 is rotatably installed on the deterioration box 101. A mating gear 105 is fixedly installed on the side bevel gear 106. The mating gear 105 meshes with the rotating drum gear 104. The rotating drum 103, the deterioration box 101, and the conductive support 102 are made of metal. The side bevel gear 106 meshes with the upper bevel gear 107. A lower transmission belt 109 is wound around the upper bevel gear 107 and the intermediate gear 108.

[0031] like Figures 2-4 As shown, two probe holders 110 are fixedly installed on the deterioration box 101, and multiple probes 111 are arranged below the probe holders 110.

[0032] like Figures 2-4 As shown, an uphill frame 113 is fixedly installed on the deterioration box 101. A blocking arc block 112 and a downhill frame 114 are fixedly installed on the uphill frame 113. The uphill frame 113 is located above the downhill frame 114, and the blocking arc block 112 is located above the uphill frame 113. The blocking arc block 112 is provided with two semi-circular arcs. The uphill frame 113 and the downhill frame 114 are made of insulating material.

[0033] The intermediate gear 108 rotates to drive the upper bevel gear 107 to rotate through the lower transmission belt 109, thereby driving the side bevel gear 106 and the butt gear 105 to rotate, thereby driving the rotating drum gear 104 and the rotating drum 103 to rotate, and the broken high-temperature-resistant material waste plastic, i.e. the plastic waste for processing of phenolic resin, is put into the rotating drum 103. High-voltage direct current is released through the probe 111 to make the air generate ion flow by electric power. The charge of the conductive material is instantaneously introduced into the ground through the rotating drum 103, the conductive support 102 and the degenerate box 101, and is not net charged. After the charge is discharged, the conductive material particles and the rotating drum 103 which are grounded generate same charge repulsion movement trajectory, so that the conductive material is bounced up and falls down while rotating with the rotating drum 103. Finally, the conductive material falls into the downhill frame 114 and is collected separately. The surface of the insulating material is adsorbed with static charge after the insulating material absorbs ions. The charge cannot be conducted away and is adsorbed on the inner wall of the rotating drum 103 by a strong electric field. Finally, when the rotating drum 103 moves to the blocking arc block 112 with the insulating material, the insulating material adsorbed on the surface of the rotating drum 103 is scraped off by the blocking arc block 112, so that the insulating material falls onto the uphill frame 113 and is collected separately. The main part of the phenolic resin to be recycled is partially charged, and the charge is not completely discharged, which generates mirror image attractive force, about 50-100 times of gravity, so that the phenolic resin slides out along the bottom of the rotating drum 103 into the degenerate box 101.

[0034] As shown in Figures 5-7 , the separating mechanism further comprises a closed cylinder 201 fixedly installed below the degenerate box 101. A lower horizontal pipe 202 is fixedly installed below the closed cylinder 201. The lower horizontal pipe 202 is fixedly installed with a vertical pipe 219. The vertical pipe 219 is rotatably installed with an inner convex gear 207 at the top. The inner convex gear 207 is slidably installed with a bidirectional threaded column 208. The bidirectional threaded column 208 is provided with a bidirectional external thread. The vertical pipe 219 is fixedly installed with an inner convex ball 209. The inner convex ball 209 slides in the bidirectional external thread of the bidirectional threaded column 208. The bidirectional threaded column 208 is fixedly installed with a lifting piece 220 below. The lifting piece 220 slides along the inner wall of the vertical pipe 219. The inner convex gear 207 is engaged with the upper gear 205.

[0035] As shown in Figures 5-7 , the discharge pipe 203 is slidably installed with a horizontal sliding column 210. The horizontal sliding column 210 is fixedly installed with a horizontal closing plate 212. The horizontal sliding column 210 is provided with a horizontal spring 211 between the horizontal sliding column 210 and the discharge pipe 203.

[0036] As shown in Figures 5-7 , the closed cylinder 201 is slidably installed with a one-way column 213. The one-way column 213 is fixedly installed with a closing piece 215. The closing piece 215 is provided with a vertical spring 214 between the closing piece 215 and the closed cylinder 201.

The outer mixing piece 216 and the inner mixing piece 217 are rotatably arranged in the modification box 101. The upper bevel gear 107 is fixedly installed with the outer mixing piece 216, and the intermediate gear 108 is fixedly installed with the inner mixing piece 217.

[0038] The intermediate gear 108 drives the inner mixing piece 217 to rotate. The intermediate gear 108 drives the upper bevel gear 107 and the outer mixing piece 216 to rotate through the lower transmission belt 109. The modification box 101 is filled with ethanol. The phenolic resin enters the modification box 101, and the phenolic resin reacts with the ethanol to become a soft solid and pass through the hole plate 218. Since the density of the soft solid of the phenolic resin is greater than that of the ethanol, the soft solid sinks in the closed cylinder 201. The closed piece 215 closes the closed cylinder 201 in the initial state. The inner convex gear 207 and the bidirectional threaded column 208 are driven to rotate by the upper gear 205. The bidirectional threaded column 208 and the lifting piece 220 are driven to screw up and down under the cooperation of the bidirectional threads of the inner convex ball 209 and the bidirectional threaded column 208. When the lifting piece 220 rises, the closed piece 215 and the one-way column 213 are pulled downward, and the vertical spring 214 is compressed. At this time, the horizontal sliding column 210 and the horizontal closing plate 212 do not move, so that the soft solid in the closed cylinder 201 enters the lower horizontal pipe 202 and the vertical pipe 219. When the lifting piece 220 rises to the uppermost end, since the bidirectional threaded column 208 is provided with bidirectional external threads, when the bidirectional threaded column 208 rises to the uppermost end, the inner convex gear 207 continues to rotate the bidirectional threaded column 208 and the lifting piece 220 begins to descend. The soft solid in the vertical pipe 219 is pressed downward by the lifting piece 220. The horizontal sliding column 210 and the horizontal closing plate 212 move outward, the horizontal spring 211 is compressed, the closed piece 215 and the one-way column 213 do not move, and the soft solid flows out from the discharge pipe 203 to the pressing box 301.

[0039] As shown in the figure, Figures 8-10 The forming mechanism includes a stand 303 fixedly installed on the pressing box 301. A motor 310 is fixedly installed on the stand 303. A motor gear 311 is fixedly installed on the motor shaft of the motor 310. A center gear 308 and an upper wheel 309 are rotatably installed on the stand 303 through a transmission shaft. The outer side of the upper wheel 309, the motor gear 311, the lower gear 206, and the intermediate gear 108 are wound with a main transmission belt 312. Three upper planetary gears 306 are rotatably installed on the stand 303. Lower planetary gears 307 are fixedly installed below the upper planetary gears 306.

The inner side of the half-tooth cylinder 305 is provided with teeth, and the outer side is provided with teeth within a range of one hundred and eighty degrees. The half-tooth cylinder 305 is engaged with the lower planetary gears 307.

[0040] As shown in the figure, Figures 8-10As shown, the stand 303 is fixedly installed with a lower convex ball 315, the pressing box 301 is provided with a slope, the pressing box 301 is slidingly installed with a lower pressing box 304, the lower pressing box 304 is provided with a heating pipe 316, the lower pressing box 304 is rotatably installed with a lower bidirectional threaded column 314, the lower bidirectional threaded column 314 is provided with a bidirectional external thread, the lower convex ball 315 slides in the bidirectional external thread of the lower bidirectional threaded column 314, the lower bidirectional threaded column 314 is fixedly installed with a stud gear 313, the stud gear 313 is engaged with the half-tooth cylinder 305, and the pressing box 301 is provided with a switch plate 302.

[0041] The soft solid flows to the lower side of the lower pressing box 304 through the slope in the pressing box 301, the motor 310 drives the motor gear 311 to rotate, the main transmission belt 312 drives the upper wheel 309, the lower gear 206 and the intermediate gear 108 to rotate, the lower gear 206 drives the upper gear 205 to rotate through the gear shaft 204, the upper wheel 309 drives the central gear 308 to rotate, the central gear 308 drives the upper planetary gear 306 and the lower planetary gear 307 to rotate, thereby driving the half-tooth cylinder 305 to rotate at a reduced speed, the half-tooth cylinder 305 drives the stud gear 313 and the lower bidirectional threaded column 314 to rotate intermittently, the lower convex ball 315 slides in the bidirectional external thread of the lower bidirectional threaded column 314, so that the lower bidirectional threaded column 314 and the lower pressing box 304 are lifted and lowered, the half-tooth cylinder 305 is engaged with the stud gear 313 once, so that the lower bidirectional threaded column 314 and the lower pressing box 304 are lifted or lowered once, then the half-tooth cylinder 305 is disengaged from the stud gear 313, when the lower pressing box 304 is lowered to the lowermost end, the lower pressing box 304 remains stationary, the heating pipe 316 heats the soft solid in the pressing box 301, and the soft solid is extruded by the lower pressing box 304, so that the phenolic resin is re-molded, and the residual ethanol is evaporated, then when the half-tooth cylinder 305 is engaged with the stud gear 313 again, the lower bidirectional threaded column 314 and the lower pressing box 304 are lifted to the uppermost end, the switch plate 302 is opened, and the molded phenolic resin is taken away, and the process is repeated.

[0042] The working principle of the plastic waste recycling device for processing high-temperature-resistant materials is as follows: the motor 310 drives the motor gear 311 to rotate, which drives the upper wheel 309, the lower gear 206 and the intermediate gear 108 to rotate through the main transmission belt 312, the lower gear 206 drives the upper gear 205 to rotate through the gear shaft 204, the upper wheel 309 drives the center gear 308 to rotate, the center gear 308 drives the upper planetary gear 306 and the lower planetary gear 307 to rotate, thereby driving the half-tooth cylinder 305 to rotate at a reduced speed, the half-tooth cylinder 305 drives the stud gear 313 and the lower double-thread column 314 to rotate intermittently, the intermediate gear 108 drives the upper bevel gear 107 to rotate through the lower transmission belt 109, thereby driving the side bevel gear 106 and the butt joint gear 105 to rotate, thereby driving the rotating drum gear 104 and the rotating drum 103 to rotate, the broken high-temperature-resistant material waste plastic, i.e., the plastic waste for processing phenolic resin, is put into the rotating drum 103, high-voltage direct current is released through the probe 111 to generate ion flow by air power, the charge of the conductor material is instantaneously introduced into the ground through the rotating drum 103, the conductive support 102 and the degenerate box 101, and no net charge is generated. After the charge is discharged, the conductive material particles and the rotating drum 103 generate same charge repulsive force motion trajectories, so that the conductive material is bounced up and falls while rotating with the rotating drum 103, and finally falls into the downhill frame 114 and is collected separately. After the insulating material absorbs ions, the surface is charged with static electricity, the charge cannot be conducted away, and is attracted to the inner wall of the rotating drum 103 by a strong electric field. Finally, when the rotating drum 103 moves to the blocking arc block 112 with the insulating material, the insulating material adsorbed on the surface of the rotating drum 103 is scraped off by the blocking arc block 112, so that the insulating material falls onto the uphill frame 113 and is collected separately. The phenolic resin part that needs to be recycled is mainly charged, the charge is not completely discharged, and mirror image attractive force is generated, which is about 50-100 times of gravity, so that the phenolic resin slides out along the bottom of the rotating drum 103 and into the degenerate box 101.The intermediate gear 108 drives the inner mixing piece 217 to rotate, and the intermediate gear 108 drives the upper bevel gear 107 and the outer mixing piece 216 to rotate through the lower transmission belt 109. The modification box 101 is filled with ethanol, and the phenolic resin enters the modification box 101, reacts with the ethanol, becomes a soft solid, and passes through the hole plate 218. Because the soft solid of the phenolic resin has a density greater than that of the ethanol, the soft solid sinks in the closed cylinder 201. The closing piece 215 is in an initial state to close the closed cylinder 201. The upper gear 205 drives the inner convex gear 207 and the bidirectional threaded column 208 to rotate. Under the cooperation of the inner convex ball 209 and the bidirectional threads of the bidirectional threaded column 208, the bidirectional threaded column 208 and the lifting piece 220 are driven to screw up and down. When the lifting piece 220 rises, the closing piece 215 and the one-way column 213 are pulled down, and the vertical spring 214 is compressed. At this time, the horizontal sliding column 210 and the horizontal closing plate 212 do not move, so that the soft solid in the closed cylinder 201 enters the lower horizontal pipe 202 and the vertical pipe 219. When the lifting piece 220 rises to the uppermost end, because the bidirectional threaded column 208 is provided with bidirectional external threads, when the bidirectional threaded column 208 rises to the uppermost end, the inner convex gear 207 continues to rotate the bidirectional threaded column 208 and the lifting piece 220 begins to descend, and the soft solid in the vertical pipe 219 is pressed downward through the lifting piece 220. The horizontal sliding column 210 and the horizontal closing plate 212 move outward, the horizontal spring 211 is compressed, the closing piece 215 and the one-way column 213 do not move, and the soft solid flows out of the discharge pipe 203 to the pressing box 301. The soft solid flows to the lower pressing box 304 through the slope in the pressing box 301. The lower bidirectional threaded column 314 and the lower pressing box 304 are lifted and lowered through the sliding of the lower convex ball 315 in the bidirectional external threads of the lower bidirectional threaded column 314. The half-tooth cylinder 305 makes the lower bidirectional threaded column 314 and the lower pressing box 304 rise or fall once every time the half-tooth cylinder 305 meshes with the screw column gear 313. Subsequently, the half-tooth cylinder 305 is disengaged from the meshing with the screw column gear 313. When the lower pressing box 304 descends to the lowermost end, the lower pressing box 304 remains stationary. The soft solid in the pressing box 301 is heated through the heating pipe 316, and the soft solid is extruded through the lower pressing box 304, so that the phenolic resin is reshaped again, and the residual ethanol is evaporated. Subsequently, when the half-tooth cylinder 305 meshes again, the lower bidirectional threaded column 314 and the lower pressing box 304 are driven to rise to the uppermost end, the switch plate 302 is opened, and the finished phenolic resin is taken away, so as to reciprocate.

[0043] The above merely provides the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art, according to the technical solution and the inventive concept of the present application, makes equivalent replacement or change within the technical scope of the present application, which should be covered within the protection scope of the present application.
