Description
Technical Field
[0001] The utility model relates to the technical field of plastic recycling, in particular to a plastic recycling and crushing device. Background Art
[0002] Plastic is a polymer compound made of synthetic resin as the main component, with or without other additives. It is widely used because of its lightness, durability, low cost, easy molding and wide range of applications. However, the mass production and consumption of plastics have led to serious environmental problems, especially the treatment and recycling of plastic waste has become a global challenge. Plastics are not easy to degrade. If they are discarded or improperly handled, they will cause long-term pollution to land, water sources and oceans. Therefore, the recycling and reuse of plastics has become particularly important. Plastic crushing and recycling is a key step in the plastic recycling process, which can be roughly divided into primary crushing, cleaning, secondary crushing and drying. Because there are relatively more steps, multiple large-scale equipment is required in the process of crushing and recycling plastics, which will increase the requirements for site area and increase the space cost during production. Utility Model Content
[0003] In order to overcome the problem that there are relatively more steps in the process of crushing and recycling plastics, multiple devices with larger floor space are needed, which will increase the requirements for site area and thus increase the space cost during production.
[0004] The technical solution of the utility model is: a plastic recycling and crushing device, comprising a segmented crushing component, a segmented stir-frying component, and a segmented drainage component; the lower end of the segmented crushing component is provided with a segmented stir-frying component for drying the secondary crushed plastic; the segmented stir-frying component is provided with a segmented drainage component for accelerating the drying process and removing moisture.
[0005] Preferably, the segmented crushing component is used for secondary crushing of the plastic, the segmented stir-frying component is used for drying the secondary crushed plastic, and the segmented drainage component is used to accelerate the drying process and remove moisture. The segmented design, the combination of crushing and the vertical direction of the low-pressure drying equipment, allows the equipment to quickly dry plastic fragments in a continuous and uninterrupted operation process, and greatly reduces the equipment's demand for site area.
[0006] Preferably, the segmented crushing assembly includes an outer frame, a crushing chamber, a first rotating shaft, a second rotating shaft, a fixed plate, a crushing blade, a gear, a motor, and a first draw plate; three crushing chambers are opened in the outer frame; the crushing chamber is connected to the first rotating shaft for common rotation; the front end of the first rotating shaft is connected to the second rotating shaft for rotation; and the inner walls of the front and rear ends of the crushing chamber are fixed with fixed plates. After the first first draw plate is opened, the plastic is poured into the first crushing chamber. The first and second rotating shafts driven by the motor and gears will perform secondary crushing on the plastic that has been initially crushed and cleaned through the crushing blades. After the wet fragments fall into the first dehumidification chamber and fill to half the height of the first dehumidification chamber, the first draw plate is pushed back to close the dehumidification chamber, and the subsequent plastic is poured into the second crushing chamber for batch processing.
[0007] Preferably, three groups of crushing blades are fixedly connected to the first rotating shaft and the second rotating shaft; gears are fixedly connected to one side of the first rotating shaft and the second rotating shaft, and the two gears are meshed with each other; the other side of the first rotating shaft is rotatably connected to a motor through a coupling; and the lower end of the crushing chamber is slidably connected to a first pumping plate.
[0008] Preferably, the segmented stir-frying assembly includes a dehumidification chamber, a third rotating shaft, a synchronous belt, a paddle, a heating plate, and a second draw plate; a dehumidification chamber is provided at the lower end of each first draw plate; a third rotating shaft is connected to the dehumidification chamber for common rotation; a synchronous belt is connected to one side of the third rotating shaft for rotation, and the upper end of the synchronous belt is connected to the first rotating shaft for rotation. When the first rotating shaft rotates, the third rotating shaft is rotated by the synchronous belt, so that the plastic fragments in the dehumidification chamber are turned over by the paddle, and the plastic fragments are heated by the heating plate at the same time.
[0009] Preferably, three groups of paddles are fixedly connected to the third rotating shaft, and each group of paddles is provided with four paddles; a heating plate is fixedly connected to one side of the paddle and the bottom end of the dehumidification chamber; and a second draw plate is slidably connected to the lower end of the dehumidification chamber.
[0010] Preferably, the segmented drainage assembly includes a cryogenic plate, heat dissipation fins, a fan, a water collecting cover, a first valve, a second valve, an exhaust pipe, and an exhaust pump; a cryogenic plate is provided above the rear end of the dehumidification chamber; heat dissipation fins are fixedly connected to the outer side of the cryogenic plate; and a fan is provided at the upper end of the heat dissipation fins. The exhaust pump extracts air from the three dehumidification chambers through the exhaust pipe to reduce the pressure inside the dehumidification chamber, but when the first exhaust plate at the upper end or the second exhaust plate at the lower end of a dehumidification chamber is extracted, the second valve at the front end of the dehumidification chamber is closed. Because the boiling point of the liquid will drop in a low-pressure environment, after the air in the dehumidification chamber is extracted, the plastic fragments in the dehumidification chamber are heated by the heating plate and turned over by the paddle, and the moisture on the surface will evaporate rapidly, and the evaporated water vapor will float upward due to its own heat. Because a large number of heat-absorbing fins are fixed on the cryopanel and there is a fan for cooling the cryopanel and the heat-absorbing fins, the upwardly floating water vapor will quickly absorb heat after contacting the cryopanel and be condensed into low-temperature droplets, which will slide down the front surface of the cryopanel and flow into the water collecting hood to complete the drying of the plastic fragments and the dehumidification of the dehumidification chamber. Then, the second drawer is pulled out to pour out the dried plastic fragments in the dehumidification chamber, and the condensed water in the water collecting hood can be discharged after the first valve is opened.
[0011] Preferably, the rear end of the dehumidification chamber is fixedly connected to a water collecting cover connected to the dehumidification chamber; the lower end of the water collecting cover is connected to a first valve; the front end of the dehumidification chamber is connected to a second valve; the front ends of the second valves are commonly connected to an exhaust pipe; and the end of the exhaust pipe is connected to an exhaust pump.
[0012] Beneficial effects of the utility model:
[0013] 1. By setting up a batch processing mechanism, a vacuum drying mechanism and a vertical combination structure, this drying device saves more site area compared to the traditional conveyor belt drying device. By combining the secondary crushing device and the drying device in a vertical direction, the site area occupied by the equipment can be further greatly reduced. The segmented design structure and batch processing method enable the equipment to process plastics continuously.
[0014] 2. After pulling open the first draw plate, pour the plastic into the first crushing chamber. The first rotating shaft and the second rotating shaft driven by the motor and the gear will perform secondary crushing on the plastic that has been initially crushed and cleaned through the crushing blade. After the wet fragments fall into the first dehumidification chamber and fill to half the height of the first dehumidification chamber, push the first draw plate back to close the dehumidification chamber, and then pour the subsequent plastic into the second crushing chamber for batch processing, so that the secondary crushing device and the drying device are vertically combined with each other to greatly reduce the site area occupied by the equipment;
[0015] 3. When the first rotating shaft rotates, the third rotating shaft rotates through the synchronous belt, so that the plastic fragments in the dehumidification chamber are turned over by the paddle, and the plastic fragments are heated by the heating plate at the same time, and the vacuum pump extracts the air in the three dehumidification chambers through the vacuum pipe to reduce the pressure inside the dehumidification chamber. However, when the first pumping plate at the upper end or the second pumping plate at the lower end of a dehumidification chamber is drawn out, the second valve at the front end of the dehumidification chamber is closed. Because the boiling point of the liquid will drop in a low-pressure environment, after the air in the dehumidification chamber is drawn out, the plastic fragments in the dehumidification chamber are heated by the heating plate and turned over by the paddle, and the moisture on the surface of the plastic fragments will evaporate rapidly. The evaporated water vapor floats upward due to its own heat, and because of the low pressure A large number of heat-absorbing fins are fixed on the temperature plate, and there is a fan for dissipating heat from the low-temperature plate and the heat-absorbing fins. Therefore, when the upward floating water vapor contacts the low-temperature plate, it will quickly absorb heat and be condensed into low-temperature droplets, which will slide down the front end surface of the low-temperature plate and flow into the water collecting hood to complete the drying of the plastic fragments and dehumidification of the dehumidification chamber. Subsequently, the second drawer plate is pulled out to pour out the dried plastic fragments in the dehumidification chamber, and the condensed water in the water collecting hood can be discharged after opening the first valve. Compared with the traditional conveyor belt drying device, this drying device saves more site area, and the equipment can continuously process plastics through the segmented design structure and batch processing method.

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0022] See also Figure 1-2The utility model provides an embodiment: a plastic recycling crushing device, comprising a segmented crushing component 1, a segmented stir-frying component 2, and a segmented drainage component 3; the lower end of the segmented crushing component 1 is provided with a segmented stir-frying component 2 for drying the secondary crushed plastic; the segmented stir-frying component 2 is provided with a segmented drainage component 3 for accelerating the drying process and removing moisture. The segmented crushing component 1 is used for secondary crushing of plastics, the segmented stir-frying component 2 is used for drying the secondary crushed plastics, and the segmented drainage component 3 is used for accelerating the drying process and removing moisture. The segmented design, the combination of crushing and the vertical direction of the low-pressure drying equipment, allows the equipment to quickly dry plastic fragments in a continuous and uninterrupted operation process, and greatly reduces the equipment's demand for site area. The segmented crushing assembly 1 includes an outer frame 101, a crushing chamber 102, a first rotating shaft 103, a second rotating shaft 104, a fixing plate 105, a crushing blade 106, a gear 107, a motor 108, and a first draw plate 109; three crushing chambers 102 are opened in the outer frame 101; the first rotating shaft 103 is connected to the crushing chamber 102 for common rotation; the front end of the first rotating shaft 103 is connected to the second rotating shaft 104 for rotation; fixing plates 105 are fixedly connected to the inner walls of the front and rear ends of the crushing chamber 102. After the first first draw plate 109 is pulled open, the plastic is poured into the first crushing chamber 102. The first rotating shaft 103 and the second rotating shaft 104 driven by the motor 108 and the gear 107 will perform secondary crushing of the plastic that has been initially crushed and cleaned through the crushing blade 106. After the wet fragments fall into the first dehumidification chamber 201 and fill to half the height of the first dehumidification chamber 201, the first draw plate 109 is pushed back to close the dehumidification chamber 201, and then the subsequent plastic is poured into the second crushing chamber 102 for batch processing. Three groups of crushing blades 106 are fixedly connected to the first rotating shaft 103 and the second rotating shaft 104; gears 107 are fixedly connected to one side of the first rotating shaft 103 and the second rotating shaft 104, and the two gears 107 are meshed with each other; the other side of the first rotating shaft 103 is rotatably connected to the motor 108 through a coupling; the lower end of the crushing chamber 102 is slidably connected to the first draw plate 109. The segmented stir-frying assembly 2 includes a dehumidification chamber 201, a third rotating shaft 202, a synchronous belt 203, a paddle 204, a heating plate 205, and a second draw plate 206; the lower end of the first draw plate 109 is provided with a dehumidification chamber 201; the dehumidification chamber 201 is connected to the third rotating shaft 202 for common rotation; one side of the third rotating shaft 202 is connected to the synchronous belt 203 for rotation, and the upper end of the synchronous belt 203 is connected to the first rotating shaft 103 for rotation. When the first rotating shaft 103 rotates, the third rotating shaft 202 is rotated through the synchronous belt 203, so that the plastic fragments in the dehumidification chamber 201 are turned over by the paddle 204, and the plastic fragments are heated by the heating plate 205 at the same time.Three groups of paddles 204 are fixedly connected to the third rotating shaft 202, and each group of paddles 204 is set to four; a heating plate 205 is fixedly connected to one side of the paddle 204 and the bottom end of the dehumidification chamber 201; and a second drawer plate 206 is slidably connected to the lower end of the dehumidification chamber 201.
[0023] See also Figure 3-4 In this embodiment, the segmented drainage assembly 3 includes a cryopanel 301, a heat dissipation fin 302, a fan 303, a water collecting cover 304, a first valve 305, a second valve 306, an exhaust pipe 307, and an exhaust pump 308; a cryopanel 301 is arranged above the rear end of the dehumidification chamber 201; the heat dissipation fin 302 is fixedly connected to the outer side of the cryopanel 301; and a fan 303 is arranged on the upper end of the heat dissipation fin 302. The vacuum pump 308 extracts the air in the three dehumidification chambers 201 through the vacuum pipe 307 to reduce the pressure inside the dehumidification chamber 201. However, when the first pumping plate 109 at the upper end or the second pumping plate 206 at the lower end of a dehumidification chamber 201 is pumped out, the second valve 306 at the front end of the dehumidification chamber 201 is closed. Because the boiling point of the liquid will drop in a low-pressure environment, after the air in the dehumidification chamber 201 is pumped out, the plastic fragments in the dehumidification chamber 201 are heated by the heating plate 205 and turned by the paddle 204, and the moisture on the surface of the plastic fragments will evaporate rapidly, and the evaporated water vapor will float upward due to its own heat. Because a large number of heat-absorbing fins 302 are fixedly connected to the cryopanel 301, and there is a fan 303 for dissipating heat from the cryopanel 301 and the heat-absorbing fins 302, when the upward floating water vapor contacts the cryopanel 301, it will quickly absorb heat and be condensed into low-temperature droplets, which will slide down the front surface of the cryopanel 301 and flow into the water collecting cover 304 to complete the drying of the plastic fragments and the dehumidification of the dehumidification chamber 201. Then, the second drawer 206 is pulled out to pour out the dried plastic fragments in the dehumidification chamber 201, and the condensed water in the water collecting cover 304 can be discharged after the first valve 305 is opened. The rear end of the dehumidification chamber 201 is fixedly connected to a water collecting cover 304 connected to the dehumidification chamber 201; the lower end of the water collecting cover 304 is connected to a first valve 305; the front end of the dehumidification chamber 201 is connected to a second valve 306; the front end of the second valve 306 is commonly connected to an exhaust pipe 307; the end of the exhaust pipe 307 is connected to an exhaust pump 308.
[0024] When working, the first first draw plate 109 is pulled open to pour the plastic into the first crushing chamber 102, and the first rotating shaft 103 and the second rotating shaft 104 driven by the motor 108 and the gear 107 will perform secondary crushing on the plastic that has been initially crushed and cleaned through the crushing blade 106, and after the wet fragments fall into the first dehumidification chamber 201 and fill to half the height of the first dehumidification chamber 201, the first draw plate 109 is pushed back to close the dehumidification chamber 201, and then the subsequent plastic is poured into the second crushing chamber 102 for batch processing, thereby combining the secondary crushing device and the drying device in a vertical direction to greatly reduce the site occupied by the equipment;
[0025] When the first rotating shaft 103 rotates, the third rotating shaft 202 is rotated through the synchronous belt 203, so that the plastic fragments in the dehumidification chamber 201 are turned over by the paddle 204, and the plastic fragments are heated by the heating plate 205 at the same time, and the air pump 308 extracts the air in the three dehumidification chambers 201 through the air extraction pipe 307 to reduce the pressure inside the dehumidification chamber 201, but when the first extraction plate 109 at the upper end or the second extraction plate 206 at the lower end of a certain dehumidification chamber 201 is extracted, the second valve 306 at the front end of the dehumidification chamber 201 is closed, because the boiling point of the liquid will decrease in a low-pressure environment, so after the air in the dehumidification chamber 201 is extracted, the plastic fragments in the dehumidification chamber 201 are heated by the heating plate 205 and turned over by the paddle 204, and the moisture on the surface thereof will evaporate rapidly;
[0026] The evaporated water vapor floats upward due to its own heat. Because a large number of heat absorbing fins 302 are fixedly connected to the cryopanel 301, and there is a fan 303 for dissipating heat to the cryopanel 301 and the heat absorbing fins 302, the upward floating water vapor will quickly absorb heat after contacting the cryopanel 301, and will be condensed into low-temperature droplets, which will slide down the front end surface of the cryopanel 301 and flow into the water collecting cover 304 to complete the drying of the plastic fragments and the dehumidification of the dehumidification chamber 201. Subsequently, the second drawer 206 is pulled out to pour out the dried plastic fragments in the dehumidification chamber 201, and the condensed water in the water collecting cover 304 can be discharged after opening the first valve 305. This allows the drying device to save more site area compared to the traditional conveyor belt drying device, and the equipment can continuously process plastics through the segmented design structure and batch processing method.
[0027] Through the above steps, a batch processing mechanism, a vacuum drying mechanism and a vertical combination structure are set up, so that the drying device can save more site area compared with the traditional conveyor belt drying device, and the secondary crushing device and the drying device are combined with each other in the vertical direction, which can further greatly reduce the site area occupied by the equipment, and the segmented design structure and batch processing method enable the equipment to continuously process plastics.
