Description

Technical Field

[0001] The present invention relates to the technical field of waste plastic recycling, and particularly relates to a waste plastic recycling and reusing device for processing. Background Art

[0002] The recycling of waste plastics is an important environmental protection action, which can effectively reduce plastic pollution and provide reusable resources. There are currently two main recycling technologies. Physical recycling method: Waste plastics are processed through mechanical means such as crushing, cleaning, and melting, and then reprocessed into new plastic products. Specifically, the collected plastic waste usually needs to be cleaned and processed to remove surface dirt, residues, and other pollutants. This step ensures that the recycled plastics are clean and suitable for further processing. The cleaned plastic waste is usually sent to a special device for crushing or breaking. This step physically decomposes the waste plastics into smaller particles or blocks for subsequent processing and treatment. The crushed plastics are fed into a melting device, and the plastics are converted into plastic liquid by heating and melting for subsequent reuse in molding.

[0003] The invention with the application number CN202411089979.4 relates to the field of waste plastic recycling and treatment, specifically a waste plastic recycling and reusing integrated device, including a cleaning treatment barrel and a stirring rod installed in the middle of the cleaning treatment barrel. A plurality of cleaning components are symmetrically installed on the stirring rod. A sliding sleeve is slidably sleeved outside the stirring rod. The cleaning component includes a plurality of abutting rods evenly distributed along the axis of the sliding sleeve and installed outside the sliding sleeve. A cleaning plate is installed at the end of each abutting rod. The blocking component provided by this invention can press down the plastic waste floating on the water surface, so that the plastic waste is completely immersed in the water. By assisting the blocking with the rubbing action of the cleaning plate, the sundries on the plastic waste can be completely cleaned. At the same time, as the cleaning plate rotates with the stirring rod, there will be a circumferential displacement with the plastic waste, and the cleaning plate will also move reciprocally in the axial direction of the stirring rod, thereby further increasing the cleaning effect of the cleaning plate on the plastic waste.

[0004] However, there are a large number of water stains on the surface of the plastic parts after the plastic is cleaned in this patent, and subsequent processing cannot be directly carried out, and the processing efficiency is relatively slow.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0021] As Figures 1 to 11 shown, a waste plastic recycling and reuse device for processing of the present invention includes: an incinerator 1, a processing mechanism 2 for preprocessing waste plastics, a feeding conveyor belt 3 for conveying waste plastics, and a cleaning rack 4 for cleaning waste plastics during the conveying process.

[0022] The feeding conveyor belt 3 conveys the waste plastics towards the processing mechanism 2. During the conveying process, the cleaning rack 4 sprays water on the surface of the waste plastics for rinsing to remove impurities or oil stains on the surface of the waste plastics, so as to avoid affecting the recycling of the waste plastics. Then, after being crushed by the processing mechanism 2, the water is removed, and then it is conveyed to the incinerator 1 to heat the waste plastics and recover the heat energy generated during incineration.

[0023] However, due to the influence of the water stains on the surface of the rinsed waste plastics, the heating temperature of the incinerator 1 is not ideal, which in turn leads to a poor recycling effect. Therefore, in this application, the processing mechanism 2 is provided to remove the water stains on the surface of the waste plastics to ensure the effect of recycling and reusing the waste plastics.

[0024] The processing mechanism 2 includes: a crushing box 21, and a feeding hopper 22 fixedly installed on the crushing box 21; the feeding hopper 22 is composed of an aggregate box 221 and a feeding box 222. The feeding box 222 is fixedly installed on the crushing box 21, and the aggregate box 221 is fixedly installed on the feeding box 222; and, a baffle plate 23 that blocks the direct feeding of the waste plastics, a hydrophobic plate 24 that guides the water on the surface of the waste plastics outside the feeding hopper 22. The baffle plate 23 is rotatably installed on the aggregate box 221, the hydrophobic plate 24 is rotatably installed on the feeding box 222, and a discharge port 25 is opened on the crushing box 21; a chute 242 is opened on the hydrophobic plate 24, and hydrophobic holes are opened on the surface of the baffle plate 23.

[0025] When in use, the feeding conveyor belt 3 conveys the waste plastics into the aggregate box 221 and accumulates on the baffle plate 23. At this time, the water liquid flows through the hydrophobic holes to the hydrophobic plate 24 and then is discharged out through the drain port 2221, realizing the removal of the water stains on the surface of the waste plastics, ensuring the effect of recycling and reusing the waste plastics, and the waste plastics accumulate on the baffle plate 23 and then are uniformly fed, realizing the intermittent centralized feeding of the waste plastics, reducing the continuous load of the equipment, reducing equipment wear, and extending the service life of the equipment.

[0026] As a supplement, both the baffle plate 23 and the hydrophobic plate 24 are inclined. When the waste plastics accumulate on the baffle plate 23, the water stains flow faster along the inclined surface under the action of gravity, and the drainage effect is better.

[0027] In addition, a second power source 241 is fixedly installed on the hydrophobic plate 24. The second power source 241 is fixedly installed on the blanking box 222. A connecting rod 231 is rotatably connected to the baffle plate 23. A slider 232 is rotatably connected to the connecting rod 231. The slider 232 is slidably connected to the chute 242. After the waste plastic water treatment on the baffle plate 23 is completed, the second power source 241 pulls the hydrophobic plate 24 to rotate, causing the connecting rod 231 to drive the slider 232 to slide inside the chute 242, pushing out the water or impurities remaining in the chute 242, cleaning the chute 242, and preventing water stains or impurities from mixing with the waste plastic, which affects the recycling and reuse of the waste plastic. After the slider 232 finishes sliding, the second power source 241 continues to pull the hydrophobic plate 24, driving the baffle plate 23 to rotate through the connecting rod 231, and then opening the baffle plate 23. The waste plastic falls from the baffle plate 23 and enters the crushing box 21 for subsequent processing. The second power source 241 is preferably an electric telescopic rod.

[0028] Generally speaking, on the one hand, the baffle plate 23 can centrally collect the waste plastic and drain the water stains on the surface of the waste plastic during the collection process. On the other hand, when the baffle plate 23 is opened, the water stains on the chute 242 are synchronously cleaned when the waste plastic falls, preventing the water stains and impurities on the chute 242 from mixing with the waste plastic, which affects the recycling and reuse of the waste plastic.

[0029] A first power source 211 is fixedly installed on the crushing box 21. A crushing roller 212 is fixedly installed on the output shaft of the first power source 211. A first gear 213 is fixedly installed on the crushing roller 212. A second gear 214 is meshed with the first gear 213. A transmission shaft is fixedly installed on the second gear 214. A conveyor belt 215 is drivenly connected to the transmission shaft. Multiple groups of crushing rollers 212 are provided. The multiple groups of crushing rollers 212 are meshed and driven through the first gear 213. After the baffle plate 23 is opened, the waste plastic falls downward onto the crushing rollers 212. The first power source 211 drives the crushing rollers 212 to rotate, crushing multiple groups of waste plastic. At the same time, the first gear 213 drives the second gear 214 to rotate, causing the conveyor belt 215 to drive the crushed waste plastic to be conveyed to the incinerator 1 through the discharge port 25, and the incinerator 1 recycles and reuses the waste plastic to avoid waste of resources.

[0030] The first power source 211 is preferably a motor.

[0031] It should be noted that when the incinerator 1 incinerates the waste plastic, waste gas and waste residue will be generated. Directly discharging the waste gas to the outside seriously pollutes the external environment. Usually, a purification device is used to purify the flue gas, but the heat remaining in the flue gas is wasted, and the heat in the flue gas will also increase the load of the purification device.

[0032] Therefore, in this application, an exhaust port 11 is provided on the incinerator 1, a protective shell 111 is fixedly installed on the exhaust port 11, a heat exchange tube 112 penetrates through the protective shell 111, a drying tube 113 is used to dry the waste plastics, a gas distribution tube 114 is connected to the drying tube 113, and one end of the heat exchange tube 112 is connected to a gas source; the drying tube 113 is connected to the heat exchange tube 112.

[0033] Specifically, since the heat exchange tube 112 is coiled around the surface of the exhaust port 11, when the gas source sends gas into the heat exchange tube 112, it can exchange heat with the temperature of the exhaust port 11 and the waste smoke, so as to reduce the impact of the high-temperature waste smoke on the purification device and ensure the use effect of the purification device. The gas in the heat exchange tube 112 moves into the drying tube 113 and the gas distribution tube 114 to dry the washed waste plastics, so as to ensure the drying effect of the waste plastics.

[0034] The gas outlet end of the gas distribution tube 114 is connected to the aggregate box 221, which can blow-dry the waste plastics temporarily stored in the aggregate box 221 and improve the treatment effect of the water stains on the surface of the waste plastics.

[0035] And on the drying tube 113, there are provided: a fixed frame 1131 connected to the drying tube 113, a reciprocating lead screw 1132 slidably connected to the fixed frame 1131, a connecting member 1134 threadedly connected to the reciprocating lead screw 1132, and the connecting member 1134 is fixedly installed on the fixed frame 1131; an exhaust pipe 1135 is connected to the fixed frame 1131, one end of the reciprocating lead screw 1132 is fixedly installed with a support rod, a straight groove is provided on the support rod, and a blade 1133 is slidably connected to the straight groove. The blade 1133 is arranged inside the fixed frame 1131, the fixed frame 1131 is fixedly installed on the crushing box 21, both ends of the reciprocating lead screw 1132 are rotatably connected to a fixing plate 11321, and a blanking plate 11322 is fixedly installed on the fixing plate 11321. The blanking plate 11322 is rotatably installed on the blanking hopper 22.

[0036] The gas is sent into the fixed frame 1131 through the drying tube 113, and then discharged into the blanking box 222 through the exhaust pipe 1135. Utilizing the characteristic that the gas floats upward by itself, it starts to dry from the bottom of the waste plastics, and the drying effect is better. That is to say, after the gas is heat-exchanged, it dries the waste plastics from the side and the bottom through the drying tube 113 and the gas distribution tube 114 respectively, and the drying effect is better.

[0037] Specifically, the gas enters the fixed frame 1131, pushes the blade 1133 to drive the reciprocating lead screw 1132 to rotate. Under the action of the connecting piece 1134, the reciprocating lead screw 1132 moves axially, and pushes the blanking plate 11322 to swing. When the waste plastic is discharged, under the action of the blanking plate 11322, the waste plastic can be quickly and evenly guided to the crushing roller 212, so that multiple groups of crushing rollers 212 synchronously crush the waste plastic, reducing the load on the local crushing roller 212 and improving the crushing efficiency of the waste plastic. It should be noted that when the reciprocating lead screw 1132 moves, attention should be paid to the fact that the support rod is slidably connected to the fixed frame 1131 to prevent the reciprocating lead screw 1132 from shaking when it moves. After the gas pushes the blade 1133 to rotate, it is discharged through the exhaust pipe 1135 to blow-dry the waste plastic, and the use effect is good.

[0038] As a further extension of the present application, a pressure relief port is provided on the exhaust pipe 1135. A piston 11352 is slidably connected to the exhaust pipe 1135. A lifting rod 11353 is fixedly installed on the piston 11352, and a push block 11354 is fixedly connected to the lifting rod 11353.

[0039] When the gas is discharged through the exhaust pipe 1135, it pushes the piston 11352 to drive the lifting rod 11353 to move upward, so that the push block 11354 pushes the baffle 23 to shake. When the piston 11352 moves past the pressure relief port 11351, the gas is discharged through the pressure relief port 11351, causing the piston 11352 and the lifting rod 11353 to move downward, and then driving the push block 11354 to move up and down to bridge the baffle 23, shaking off the moisture on the waste plastic, further improving the treatment effect of the moisture on the surface of the waste plastic, and the use effect is good.

[0040] Generally speaking, when the waste gas discharged from the incinerator 1 is cooled by the heat exchange tube 112, on the one hand, the heated gas after heat exchange is blown from the bottom and side of the waste plastic to the waste plastic to remove the moisture on the surface of the waste plastic. On the other hand, when the gas enters the inside of the fixed frame 1131, it drives the blade 1133 to rotate, causing the reciprocating lead screw 1132 to drive the blanking plate 11322 to swing, making the blanking of the waste plastic more uniform. When the gas is discharged from the exhaust pipe 1135, the push block 11354 knocks on the baffle 23, further improving the treatment effect of the moisture on the surface of the waste plastic, and the use effect is good.
