Description

Technical Field

[0001] The present invention relates to the technical field of plastic production equipment, and particularly to a plastic recycling granulation equipment with intelligent temperature control function. Background Art

[0002] Plastic waste is difficult to degrade naturally. If not properly treated, it will cause environmental pollution and waste of resources. Against the background of the improvement of environmental awareness and the increasing shortage of resources, the concept of circular economy has been gradually promoted and practiced, which has led to the rapid development of plastic recycling granulation equipment and its wide application in the manufacturing industry, solving the problem of recycling and reusing plastic waste.

[0003] In the prior art, for plastic recycling and reuse, waste plastics need to be first cleaned and dried, then the dried waste plastics are crushed, and then other treatments are carried out. Therefore, multiple devices are required to cooperate for plastic recycling and reuse, which increases energy consumption. Moreover, since the cleaning, drying, and crushing processes of waste plastics are mostly not carried out in the same device, when treating waste plastics, the waste plastics need to be transported to each device for treatment, which consumes a lot of time for transportation, thus reducing the recycling and reuse efficiency of waste plastics.

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] See also Figures 1-8As shown in the figure, a plastic recycling granulation device with intelligent temperature control function includes a base 1; the top end of the outer wall of the base 1 is fixedly connected with a box body 2 through a group of columns; a feed inlet 3 is arranged at the top end of the outer wall of the box body 2; a discharge pipe 4 is arranged at the bottom end of the outer wall of the box body 2; a water outlet pipe 5 is arranged on one side of the outer wall of the box body 2, and valves are arranged in the water outlet pipe 5, the feed inlet 3 and the discharge pipe 4; a drying device 6 is arranged on one side of the outer wall of the box body 2; an air duct 7 is arranged at the output end of the drying device 6, and one end of the outer wall of the air duct 7 extends into the box body 2; a sealing plate 8 is arranged in the box body 2; a switching mechanism is arranged on one side of the outer wall of the sealing plate 8, and the sealing plate 8 is opened and closed through the switching mechanism; a crushing mechanism is arranged in the box body 2, and the crushing mechanism is located below the sealing plate 8; the top end of the outer wall of the box body 2 is fixedly connected with a motor 9 through a fixing block; a rotating shaft 10 is arranged at the output end of the motor 9, and the bottom end of the outer wall of the rotating shaft 10 extends into the box body 2; a group of stirring plates 11 are fixedly connected to the outer side wall of one end of the rotating shaft 10 located in the box body 2; the switching mechanism and the crushing mechanism are both driven by the motor 9. By putting waste plastics into the box body 2 from the feed inlet 3, at this time the waste plastics fall onto the sealing plate 8. Then water, chemicals, etc. are put into the box body 2. Then the motor 9 drives the rotating shaft 10 to rotate, thereby driving the stirring plates 11 to rotate, so that the waste plastics are subjected to a cleaning process. When the waste plastics are cleaned, the valve at the water outlet pipe 5 is opened to drain the water. Then the waste plastics are dried through the drying device 6. At this time, the waste plastics have completed the two processes of cleaning and drying. And when the waste plastics are cleaned and dried, the sealing plate 8 is opened through the switching mechanism, and then the waste plastics are crushed by the crushing mechanism, so that the device completes the cleaning, drying and crushing processes of waste plastics through a single motor 9, thereby reducing energy consumption while omitting the transportation process and improving the recycling efficiency of waste plastics.

[0031] The switch mechanism includes a toggle plate 12; the sealing plate 8 includes a left plate 801 and a right plate 802; first through grooves 13 are provided on opposite sides of the outer wall of the box body 2, and the outer side walls of the left plate 801 and the right plate 802 are respectively slidably connected to the inner side walls of a pair of first through grooves 13; a second through groove 14 is provided on one side of the outer wall of the left plate 801; an arc block 15 is fixedly connected to one side of the inner wall of the second through groove 14 through a first spring; a rotating rod 16 is rotatably connected to one side of the outer wall of the box body 2 through a connecting block; a sprocket 17 is fixedly connected to the top of the outer wall of the rotating rod 16 and the outer side wall of the rotating shaft 10, and a pair of sprockets 17 are connected by a chain 18; one end of the outer wall of a group of toggle plates 12 is fixedly connected to the outer side wall of the rotating rod 16, and the toggle plates 12 match the arc block 15, and the rotating shaft 10 is driven to reverse by the motor 9, so that the rotating shaft 10 drives the rotating rod 16 through the sprocket 17 and the chain 18. The reverse rotation rod 16 drives the toggle plate 12 to reverse, and the reversed toggle plate 12 will encounter the plane of the arc block 15. At this time, the toggle plate 12 continues to rotate, driving the arc block 15 to move, so that the arc block 15 drives the left plate 801 to move. At this time, the sealing plate 8 is opened, and the waste plastic falls off. When the rotating rod 16 drives the toggle plate 12 to rotate forward, the toggle plate 12 will encounter the arc surface of the arc block 15. At this time, the arc block 15 will shrink and will not drive the left plate 801 to move, so that when the waste plastic is cleaned, the sealing plate 8 is in a sealed state. After the waste plastic is cleaned and dried, the left plate 801 is moved, the sealing plate 8 is opened, and the waste plastic falls off. While the cleaning and drying are completed in the box body 2 of the device, it also makes it convenient for the waste plastic to carry out further processes, and there is no need to take out and transport the waste plastic, thereby reducing the time for taking out and transporting the waste plastic, and further improving the recycling efficiency of the waste plastic.

[0032] The crushing mechanism includes a crushing roller 19; one ends of the outer walls of a pair of crushing rollers 19 are rotatably connected to one side of the inner wall of the box body 2; one ends of the outer walls of the pair of crushing rollers 19 are fixedly connected with a first rotating rod 20 and a second rotating rod 21 respectively, and one ends of the outer walls of the first rotating rod 20 and the second rotating rod 21 penetrate through the box body 2; the outer side walls of one ends of the first rotating rod 20 and the second rotating rod 21 located outside the box body 2 are fixedly connected with a first gear 22, and the pair of first gears 22 are meshed with each other; one end of the outer wall of the first rotating rod 20 is fixedly connected with a second bevel gear 23; one side of the outer wall of the box body 2 is rotatably connected with a first round rod 24 through a first square block; the outer top end of the first round rod 24 and the outer side wall of the rotating shaft 10 are fixedly connected with a second sprocket 25, and the pair of second sprockets 25 are connected through a second chain 26; the bottom end of the outer wall of the second round rod is fixedly connected with a third bevel gear 27, and the third bevel gear 27 is meshed with the second bevel gear 23. By the rotation of the rotating shaft 10, the first round rod 24 is driven to rotate through the second sprocket 25 and the second chain 26. The first round rod 24 drives the second bevel gear 23 and the first rotating rod 20 to rotate through the third bevel gear 27. The first rotating rod 16 drives the second rotating rod 21 to rotate through the pair of first gears 22, so that the pair of crushing rollers 19 rotate towards the center position, and then the waste plastics are crushed, completing the rough crushing process of the waste plastics, making the cleaning, drying and rough crushing processes of the waste plastics relatively simple.

[0033] One side of the inner wall of the box body 2 is rotatably connected with a third rotating rod 31 and a fourth rotating rod 32; a group of crushing blades 33 are fixedly connected to the outer side walls of the third rotating rod 31 and the fourth rotating rod 32, and the two groups of crushing blades 33 are distributed alternately; one ends of the outer walls of the third rotating rod 31 and the fourth rotating rod 32 penetrate through the box body 2; the outer side walls of one ends of the third rotating rod 31 and the fourth rotating rod 32 located outside the box body 2 are fixedly connected with fifth gears 34, and the pair of fifth gears 34 are meshed with each other; one ends of the outer walls of the third rotating rod 31 and the second rotating rod 21 are fixedly connected with third sprockets 35, and the pair of third sprockets 35 are connected through a third chain 36. By the rotation of the second rotating rod 21, the third rotating rod 31 is driven to rotate through the third sprocket 35 and the third chain 36. The third rotating rod 31 drives the fourth rotating rod 32 to rotate through the pair of fifth gears 34, thereby driving the two groups of crushing blades 33 to rotate rapidly. Since the radius of the third sprocket 35 at the second rotating rod 21 is larger than the radius of the third sprocket 35 at the third rotating rod 31, the rotating speed of the crushing blades 33 is relatively fast, so that the waste plastics after the rough crushing process are further crushed by the two groups of crushing blades 33, completing the fine crushing process of the waste plastics, thus facilitating the next process, further reducing the volume of the waste plastics, making it more convenient for them to be melted, and thus improving the melting efficiency of the waste plastics.

[0034] At the top of the outer wall of the base 1, a melting and extrusion shell 37 is fixedly connected through a first support plate; the bottom end of the outer wall of the discharge pipe 4 is fixedly connected to the outer side wall of the melting and extrusion shell 37, and the discharge pipe 4 is connected to the melting and extrusion shell 37; on one side of the inner wall of the melting and extrusion shell 37, a screw body 38 is rotatably connected, and one end of the outer wall of the screw body 38 penetrates through the melting and extrusion shell 37; on one end of the outer walls of the screw body 38 and the fourth rotating rod 32, a fourth sprocket 39 is fixedly connected, and a pair of fourth sprockets 39 are connected through a fourth chain 40; a heating system is provided inside the melting and extrusion shell 37; at the top of the outer wall of the base 1, a cooling water tank body 41 is fixedly connected through a second support plate, and the cooling water tank body 41 matches the melting and extrusion shell 37; intelligent temperature control systems are provided inside both the cooling water tank body 41 and the melting and extrusion shell 37. Due to the rotation of the fourth rotating rod 32 driving the screw body 38 to rotate through the fourth sprocket 39 and the fourth chain 40, when the waste plastic is finely crushed and falls to the bottom of the box body 2, at this time, by opening the valve at the discharge pipe 4, the waste plastic falls into the melting and extrusion shell 37. At this time, the heating system heats the waste plastic, and the intelligent temperature control system is responsible for monitoring the temperature change to keep the temperature in a suitable range. When the waste plastic melts, the rotation of the screw body 38 drives the molten waste plastic to move forward until it is extruded from the melting and extrusion shell 37. At this time, the waste plastic is melted into a long strip shape. At this time, the long strip-shaped waste plastic is placed in the cooling water tank body 41 to quickly cool and form the waste plastic, completing the hot melt forming process of the waste plastic. Because there is also an intelligent temperature control system inside the cooling water tank body 41, it is convenient to monitor the temperature inside the cooling water tank body 41 and adjust the temperature.

[0035] On one side of the outer wall of the left plate 801, a first rack 28 is fixedly connected through a second connecting plate; on one side of the outer wall of the right plate 802, a second rack 29 is fixedly connected through a third connecting plate; on one side of the outer wall of the box body 2, a fourth gear 30 is rotatably connected through a second round rod, and both the second gear and the first rack 28 are meshed with the fourth gear 30. When the left plate 801 moves, the left plate 801 drives the first rack 28 to move through the second connecting plate. Because the first rack 28 is meshed with the fourth gear 30, the movement of the first rack 28 drives the fourth gear 30 to rotate. Because the fourth gear 30 is also meshed with the second rack 29, the rotation of the fourth gear 30 drives the second rack 29 to move, so that the second rack 29 drives the right plate 802 to move, causing the left plate 801 and the right plate 802 to move towards the center or towards both sides simultaneously, so that the left plate 801 and the right plate 802 are opened simultaneously or sealed simultaneously, increasing the opening gap of the sealing plate 8 and increasing the dropping speed of the waste plastic.

[0036] One side of the outer wall of the discharge pipe 4 is rotatably connected with a sixth rotating rod 42, and one end of the outer wall of the sixth rotating rod 42 penetrates through the discharge pipe 4; a gear eight 43 is fixedly connected to one end of the outer wall of the sixth rotating rod 42 and the outer side wall of the screw body 38, and a pair of gears eight 43 are meshed with each other; a set of cutting blades 44 is fixedly connected to the outer side wall of the sixth rotating rod 42, and the cutting blades 44 are matched with the cooling water tank body 41. The screw body 38 drives the sixth rotating rod 42 to rotate through a pair of gears eight 43, so that the sixth rotating rod 42 drives a set of cutting blades 44 to rotate. Because the cutting blades 44 are matched with the cooling water tank body 41, when the cooled and solidified plastic strip moves out of the cooling water tank body 41 by a certain length, the cutting blades 44 cut it, so that the plastic strip is cut into granular form, completing the granulation process of waste plastics.

[0037] Embodiment 2:

[0038] Please refer to Figure 6 and Figure 9 As shown, one side of the outer wall of the box body 2 is rotatably connected with an eighth rotating rod 45 through a fifth square plate; sprockets eight 46 are fixedly connected to the outer side walls of the eighth rotating rod 45 and the rotating rod 16, and a pair of sprockets eight 46 are meshed with each other through a chain eight 47; the top end of the outer wall of the box body 2 is fixedly connected with a sliding plate 49; one side of the outer wall of the sliding plate 49 is slidably connected with a screening shell 50; one side of the outer wall of the screening shell 50 is hinged with a connecting rod 51; the bottom end of the outer wall of the eighth rotating rod 45 is fixedly connected with an adjusting gear 52; the bottom end edge of the outer wall of the adjusting gear 52 is rotatably connected with an adjusting rod 53, and the bottom end of the outer wall of the adjusting rod 53 is rotatably connected to the top end of the outer wall of the connecting rod 51. The rotation of the rotating rod 16 drives the eighth rotating rod 45 to rotate through the sprockets eight 46 and the chain eight 47, so that the eighth rotating rod 45 drives the adjusting gear 52 to rotate, the rotation of the adjusting gear 52 drives the adjusting rod 53 to move, the movement of the adjusting rod 53 drives the connecting rod 51 to move, and the connecting rod 51 will change its angle when moving. However, because the connecting rod 51 is hinged to the screening shell 50, the connecting rod 51 moves while changing its angle, thereby driving the screening shell 50 to move, and the screening shell 50 moves back and forth, generating shaking and vibration, so as to screen the plastic particles in the screening shell 50, thereby removing unqualified particles or leaving unqualified particles, thus completing the screening process of plastic particles, making the device more efficient, fast, and facilitating the recycling and reuse of waste plastics.

[0039] When the present invention is in use, the waste plastics are put into the box body 2 from the feed inlet 3. At this time, the waste plastics fall onto the sealing plate 8. Then, water, chemicals, etc. are put into the box body 2, and then the motor 9 drives the rotating shaft 10 to rotate, thereby driving the stirring plate 11 to rotate, so as to carry out the cleaning process on the waste plastics. When the waste plastics are cleaned, the valve at the water outlet pipe 5 is opened to drain the water, and then the waste plastics are dried by the drying device 6. At this time, the waste plastics have completed the two processes of cleaning and drying.

[0040] After the waste plastic is cleaned and dried, the motor 9 drives the rotating shaft 10 to reverse, so that the rotating shaft 10 drives the rotating rod 16 to reverse through the first sprocket 17 and the first chain 18, and the reversed rotating rod 16 drives the dialing plate 12 to reverse. The reversed dialing plate 12 will encounter the plane of the arc-shaped block 15. At this time, the dialing plate 12 continues to rotate, driving the arc-shaped block 15 to move, so that the arc-shaped block 15 drives the left plate 801 to move. At this time, the sealing plate 8 opens, and the waste plastic drops. When the rotating rod 16 drives the dialing plate 12 to rotate forward, the dialing plate 12 will encounter the arc surface of the arc-shaped block 15. At this time, the arc-shaped block 15 will contract and will not drive the left plate 801 to move. When the waste plastic is cleaned, the sealing plate 8 is in a sealed state. After the waste plastic is cleaned and dried, it is reversed to move the left plate 801, and the sealing plate 8 opens, so that the waste plastic drops.

[0041] When the left plate 801 moves, the left plate 801 drives the first rack 28 to move through the second connecting plate. Since the first rack 28 meshes with the fourth gear 30, the movement of the first rack 28 drives the fourth gear 30 to rotate. Since the fourth gear 30 also meshes with the second rack 29, the rotation of the fourth gear 30 drives the second rack 29 to move, so that the second rack 29 drives the right plate 802 to move, so that the left plate 801 and the right plate 802 move towards the center or move towards both sides at the same time, so that the left plate 801 and the right plate 802 open at the same time, or are sealed at the same time.

[0042] When the waste plastic drops from the sealing plate 8, the waste plastic drops between a pair of crushing rollers 19. At this time, the rotation of the rotating shaft 10 drives the first round rod 24 to rotate through the second sprocket 25 and the second chain 26. The first round rod 24 drives the second bevel gear 23 and the first rotating rod 20 to rotate through the third bevel gear 27. The first rotating rod 16 drives the second rotating rod 21 to rotate through a pair of first gears 22, so that a pair of crushing rollers 19 rotate towards the center position, and then the waste plastic is crushed, completing the rough crushing process of the waste plastic.

[0043] When the waste plastic drops between a pair of crushing rollers 19 after completing the rough crushing process, the rotation of the second rotating rod 21 drives the third rotating rod 31 to rotate through the third sprocket 35 and the third chain 36. The third rotating rod 31 drives the fourth rotating rod 32 to rotate through a pair of fifth gears 34, so as to drive the two groups of crushing blades 33 to rotate rapidly. Since the radius of the third sprocket 35 at the second rotating rod 21 is larger than the radius of the third sprocket 35 at the third rotating rod 31, the rotation speed of the crushing blades 33 is relatively fast, so that the waste plastic after completing the rough crushing process is further crushed by the two groups of crushing blades 33, completing the fine crushing process of the waste plastic, thus facilitating the next process.

[0044] When the fourth rotating rod 32 rotates, the rotating sprocket four 39 of the fourth rotating rod 32 and the chain four 40 drive the screw body 38 to rotate. When the waste plastic is finely crushed and falls to the bottom of the box body 2, at this time, by opening the valve at the discharge pipe 4, the waste plastic falls into the melting and extrusion shell 37. At this time, the heating system heats the waste plastic, and the intelligent temperature control system is responsible for monitoring the temperature change to keep the temperature in a suitable range. When the waste plastic melts, the rotation of the screw body 38 drives the molten waste plastic to move forward until it is extruded from the melting and extrusion shell 37. At this time, the waste plastic is melted into a long strip shape. At this time, the long strip-shaped waste plastic is placed in the cooling water tank body 41 to quickly cool and form the waste plastic, completing the hot melt forming process of the waste plastic. Because the cooling water tank body 41 also has an intelligent temperature control system, it is convenient to monitor and adjust the temperature in the cooling water tank body 41.

[0045] When the screw body 38 rotates, the screw body 38 drives the sixth rotating rod 42 to rotate through a pair of gears eight 43, so that the sixth rotating rod 42 drives a group of cutting blades 44 to rotate. Because the cutting blades 44 match the cooling water tank body 41, when the cooled and solidified plastic strip moves out of the cooling water tank body 41 by a certain length, the cutting blades 44 cut it, and the plastic strip is cut into granular shape, completing the granulation process of the waste plastic.

[0046] When the plastic strip is cut into granular shape, the plastic particles fall into the screening shell 50. At this time, the rotation of the rotating rod 16 drives the eighth rotating rod 45 to rotate through the sprocket eight 46 and the chain eight 47, so that the eighth rotating rod 45 drives the adjusting gear 52 to rotate, and the rotation of the adjusting gear 52 drives the adjusting rod 53 to move, and the movement of the adjusting rod 53 drives the connecting rod 51 to move. When the connecting rod 51 moves, its angle will change. However, because the connecting rod 51 is hinged to the screening shell 50, the connecting rod 51 moves while changing its angle, thereby driving the screening shell 50 to move, and the screening shell 50 moves back and forth, generating jitter and vibration, so that the plastic particles in the screening shell 50 are screened, thereby removing unqualified particles or leaving unqualified particles, thus completing the screening process of the plastic particles.

[0047] Because this device completes the processes of cleaning, drying, coarse crushing, fine crushing, hot melt forming, granulation, screening, etc. of waste plastic through a single motor 9, this device not only saves energy, but also eliminates the need to transport the waste plastic, thus saving transportation time and improving the recycling efficiency of waste plastic. And because this device works continuously, the recycling of waste plastic is more convenient, fast and practical.
