Description

Technical Field

[0001] The invention belongs to the field of plastic product production and processing equipment, in particular to a recycled plastic particle storage, drying and conveying system. Background Art

[0002] Recycled plastic particles, also known as recycled particles, are plastic raw materials made by recycling, cleaning, sorting and other pre-treatment of waste plastics, and then processing them through physical or chemical methods such as melt extrusion granulation and modification. After the recycled plastic particles are cut, in order to clean the dust generated during cutting, the recycled plastic particles are rinsed. At the same time, in order to prevent the recycled plastic particles from agglomerating, the wet recycled plastic particles need to be dried. In addition, the storage and dry transportation method can effectively prevent the recycled plastic particles from moisture, contamination and deterioration during storage and transportation, thereby improving the quality stability of the particles.

[0003] The patent with the announcement number CN115246178B discloses a storage, drying and transportation device for recycled plastic particles, including a machine body, in which are arranged: a water filter box, a drying box and a water collection box, the water filter box is used to remove excess water from plastic particles, the drying box is used to dry plastic particles, and the water collection box is used to store water from plastic particles; a water filter mechanism, the water filter mechanism is used to filter excess water from plastic particles; a flipping mechanism, the flipping mechanism is used to flip plastic particles to achieve dynamic heating and drying. The patent uses two cams to alternately offset two water filter plates respectively, and the two water filter plates are deflected in a wave shape, so that the plastic particles are thrown up and down to throw out the excess water in the plastic particles, so as to increase the drying rate of the plastic particles; the rotating rod drives the long frame to slide back and forth on the bracket, and the L-shaped rod drives the flipping rod to deflect up and down, flipping the falling plastic particles, so as to increase the drying rate of the plastic particles.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] Although the plastic particles can be tossed up and down by two water filter plates to shake out the excess water in the plastic particles and allow the water to pass through the through holes on the water filter plates to increase the drying rate of the plastic particles, after the recycled plastic particles are cleaned, the water attached to the surface will contain impurities such as dust. When the excess water in the plastic particles is shaken out, the impurities will also be shaken out, and the impurities may adhere to the wall of the through hole, causing the through hole to be blocked, affecting the passage of water and reducing the drying efficiency.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The recycled plastic granule storage, drying and conveying system described in the present invention is to put the plastic granules to be dried into the drying frame, then close the box cover, and use a hot air blower to make the hot air pass through the branch pipe and the long pipe and then be discharged from the air outlet to dry the plastic granules. At the same time, turn on the electromagnetic vibrator, and under the action of the spring damper, the drying frame vibrates, so that the plastic granules are tossed up and down to get rid of the surplus moisture.

[0021] 2. The storage, drying and conveying system of recycled plastic particles described in the present invention utilizes an anti-particle extrusion type flipping dredging mechanism, which can drive multiple dredging rods to pass through multiple through holes during the process of the water filter plate tossing the plastic particles. Under the action of the dredging rods and the through hole walls against each other, impurities attached to the through hole walls are pushed out, thereby achieving the removal of impurities attached to the through hole walls of multiple groups of through holes, avoiding the situation where impurities block the through holes, ensuring the normal passage of water, and improving the drying efficiency; and because the dredging rods are in the cavity formed by the concave plate and the drying frame when working, the dredging rods can be prevented from passing through the through holes. The plastic particles will be squeezed out of the through holes, ensuring that the plastic particles can be continuously above the water filter plate without being disturbed by the dredging rod. In addition, during the lateral movement of the concave plate, the paddle plate can be used to lift the plastic particles accumulated on one side of the concave plate and push them to the other side of the concave plate, thereby avoiding the situation in which the concave plate pushes the plastic particles in one direction when the concave plate moves laterally, resulting in the accumulation of plastic particles and the uneven drying of the plastic particles at the bottom layer. In addition, the push of the paddle plate can further promote the scattering of the plastic particles, which is beneficial to increase the wind-receiving area of ​​the plastic particles and further improves the drying efficiency.

[0022] 3. In the recycled plastic particle storage, drying and conveying system described in the present invention, when the concave plate moves laterally, the scraper will also move laterally under the action of the motor five driving the threaded rod four to rotate. When the dredging rod passes through the water filter plate and the lower end surface of the dredging rod is flush with the lower end surface of the water filter plate, the upper end of the scraper will form a scraping with the bottom of the dredging rod to scrape off the impurities attached to the bottom of the dredging rod, thereby realizing self-cleaning of the impurities attached to the bottom of the dredging rod and avoiding the impurities falling into the inner cavity of the concave plate again when the dredging rod is reset, thereby affecting the operation of the inner cavity components of the concave plate.

[0023] 4. The recycled plastic granule storage, drying and conveying system described in the present invention can be moved by holding the handle and using universal wheels to facilitate transportation. BRIEF DESCRIPTION OF THE DRAWINGS

Both ends of the threaded rod 4 25 are rotatably arranged on the drying frame 7.

[0047] Specifically, the recycled plastic particles, also known as recycled particles, are plastic raw materials that are remade by pre-processing waste plastics such as recycling, cleaning, and sorting, and then processed by physical or chemical methods such as melt extrusion granulation and modification. After the recycled plastic particles are cut, in order to clean the dust generated during cutting, the recycled plastic particles are rinsed. At the same time, in order to prevent the recycled plastic particles from agglomerating, the wet recycled plastic particles need to be dried. In addition, by storing, drying and transporting, the recycled plastic particles can be effectively prevented from being damp, polluted and deteriorated during storage and transportation, thereby improving the quality stability of the particles. When the existing recycled plastic particle storage, drying and transportation device is used, although the two water filter plates 10 can be used to toss the plastic particles up and down to throw out the surplus water in the plastic particles to increase the drying rate of the plastic particles, after the recycled plastic particles are washed, the water attached to the surface thereof will also contain impurities such as dust. When the surplus water in the plastic particles is thrown out, the impurities will also be thrown out, and the impurities may be attached to the hole wall of the through hole 23, thereby causing the through hole 23 to be blocked, affecting the passage of water and reducing the drying efficiency.

[0048] Therefore, in order to solve the above problems, when using this embodiment, the plastic particles to be dried are placed in the drying frame 7, and then the box cover 2 is closed, and the hot air blower 27 is used to make the hot air pass through the branch pipe 30 and the long pipe 5 and then be discharged from the air outlet 6 to dry the plastic particles. At the same time, the electromagnetic vibrator 28 is turned on, and under the action of the spring damper 11, the drying frame 7 is vibrated, so that the plastic particles are thrown up and down to throw out the surplus water. At the same time, the hot air blown out can improve the drying rate of the plastic particles.

[0049] At the same time, the motor 19 is turned on. Under the action of the motor 19 driving the threaded rod 18 to rotate, the concave plate 12 is moved horizontally to the left and right, so that the multiple dredging rods 15 are aligned with the multiple groups of through holes 23 in sequence. When the dredging rods 15 are aligned with the through holes 23, the motor 219 is started and drives the threaded rod 320 to rotate, so that the mounting plate 18 moves on the threaded rod 320 and the slide bar 17, so that the dredging rod 15 passes through the through holes 23. Under the action of the dredging rod 15 and the hole wall of the through hole 23, the impurities attached to the hole wall of the through hole 23 can be pushed out, and then the dredging rod 15 is reset, and then the concave plate 12 continues to move, so that the dredging rod 15 is aligned with the next group By repeating the above-mentioned actions, impurities attached to the hole walls of multiple groups of through holes 23 can be removed, thereby avoiding the situation where impurities block the through holes 23, ensuring the normal passage of water, and improving the drying efficiency; and, since the dredging rod 15 is in the cavity formed by the concave plate 12 and the drying frame 7 when working, the concave plate 12 will also use its edge to push the plastic particles when moving, so that the dredging rod 15 will not squeeze the plastic particles out of the through holes 23 when passing through the through holes 23, ensuring that the plastic particles can be continuously located above the water filter plate 10 without being disturbed by the dredging rod 15;

[0050] When the dredging rod 15 passes through the through hole 23, impurities will also be attached to its end. When the dredging rod 15 is reset, these impurities may fall into the inner cavity of the concave plate 12. When the number of impurities accumulated in the inner cavity of the concave plate 12 is too large, it will affect the operation of the inner cavity components of the concave plate 12. Therefore, when the concave plate 12 moves laterally, the scraper 24 will also move laterally under the action of the motor 5 26 driving the threaded rod 4 25 to rotate. When the dredging rod 15 passes through the water filter plate 10 and the lower end surface of the dredging rod 15 is flush with the lower end surface of the water filter plate 10, the upper end of the scraper 24 will form a scraping with the bottom of the dredging rod 15 to scrape off the impurities attached to the bottom of the dredging rod 15, thereby realizing the self-cleaning of the impurities attached to the bottom of the dredging rod 15, and avoiding the situation that when the dredging rod 15 is reset, the impurities fall into the inner cavity of the concave plate 12 again, thereby affecting the operation of the inner cavity components of the concave plate 12;

[0051] When the concave plate 12 moves horizontally to the left and right, the concave plate 12 will push the plastic particles in one direction. When the plastic particles are pushed in one direction, accumulation will occur. When the plastic particles are accumulated, the plastic particles at the bottom will not be dried evenly. Therefore, when the concave plate 12 moves horizontally, the angle between the paddle plate 13 on one side of the moving direction of the concave plate 12 and the end surface of one side of the concave plate 12 is ninety degrees, and the paddle plate 13 on the other side is parallel to the end surface of one side of the concave plate 12. When the plastic particles accumulate on one side of the concave plate 12, the motor 3 21 drives the threaded rod 2 16 to rotate, so that the slide plate 14 moves from bottom to top, so as to use the paddle plate 13 to push the plastic particles until the paddle plate 1 3 moves to the top, and then the motor 22 drives the paddle plate 13 to rotate to push the plastic particles in the opposite direction of the moving direction, so that the plastic particles can fall to the other side of the concave plate 12, and then repeat the above action, the accumulated plastic particles can be lifted and pushed to the other side of the concave plate 12 during the lateral movement of the concave plate 12, thereby avoiding the situation that when the concave plate 12 moves horizontally, the concave plate 12 pushes the plastic particles in one direction, thereby causing the plastic particles to accumulate and the plastic particles at the bottom cannot be dried evenly, and the push of the paddle plate 13 can further promote the scattering of the plastic particles, which is beneficial to increase the wind receiving area of ​​the plastic particles and further improve the drying efficiency;

[0052] Therefore, by utilizing the anti-particle extrusion type flipping dredging mechanism, the plurality of dredging rods 15 can be driven to pass through the plurality of through holes 23 during the process of the water filter plate 10 tossing the plastic particles. Under the action of the dredging rods 15 and the hole walls of the through holes 23 being opposed, the impurities attached to the hole walls of the through holes 23 are pushed out, thereby achieving the removal of impurities attached to the hole walls of the plurality of through holes 23, avoiding the situation where the through holes 23 are blocked by impurities, ensuring the normal passage of water, and improving the drying efficiency. In addition, since the dredging rods 15 are in the cavity formed by the concave plate 12 and the drying frame 7 when working, the dredging rods 15 will not squeeze the plastic particles out of the through holes 23 when passing through the through holes. The hole 23 ensures that the plastic particles can be continuously above the water filter plate 10 without being disturbed by the dredging rod 15, and the plastic particles accumulated on one side of the concave plate 12 can be lifted by the paddle plate 13 during the lateral movement of the concave plate 12, and pushed to the other side of the concave plate 12, thereby avoiding the situation in which the concave plate 12 pushes the plastic particles in one direction when the concave plate 12 moves laterally, resulting in the accumulation of plastic particles and the uneven drying of the plastic particles at the bottom layer. In addition, the push of the paddle plate 13 can further promote the scattering of the plastic particles, which is beneficial to increase the wind-receiving area of ​​the plastic particles and further improves the drying efficiency.

[0053] In this embodiment, Figure 1 As shown, a plurality of universal wheels 3 are provided on the lower end surface of the drying box 1, and handles 4 are fixedly connected to the front and rear ends of the lower side of the right end surface of the drying box 1;

[0054] Specifically, the entire drying box 1 can be moved by holding the handle 4 and utilizing the universal wheels 3 for easy transportation.

[0055] Working principle: Hold the handle 4 and use the universal wheel 3 to move the entire drying box 1 for easy transportation. Put the plastic particles to be dried into the drying frame 7, then close the box cover 2, use the hot air blower 27 to make the hot air pass through the branch pipe 30 and the long pipe 5 and then be discharged from the air outlet 6 to dry the plastic particles. At the same time, turn on the electromagnetic vibrator 28, and under the action of the spring damper 11, the drying frame 7 vibrates, so that the plastic particles are thrown up and down to throw out the surplus moisture. At the same time, with the hot air blown out, the drying rate of the plastic particles can be increased; at the same time, turn on the motor 9, and under the action of the motor 9 driving the threaded rod 8 to rotate, The concave plate 12 is moved horizontally to the left and right, so that the multiple dredging rods 15 are aligned with the multiple groups of through holes 23 in sequence. When the dredging rods 15 are aligned with the through holes 23, the motor 2 19 is started and drives the threaded rod 3 20 to rotate, so that the mounting plate 18 moves on the threaded rod 3 20 and the slide bar 17, so that the dredging rods 15 pass through the through holes 23. Under the action of the dredging rods 15 and the hole walls of the through holes 23 being abutted, the impurities attached to the hole walls of the through holes 23 can be pushed out, and then the dredging rods 15 are reset, and then the concave plate 12 continues to move, so that the dredging rods 15 are aligned with the next group of through holes 23, and the above actions are repeated to realize the removal of impurities attached to the hole walls of the multiple groups of through holes 23, thereby avoiding the occurrence of impurities blocking the through holes 23. 3, ensuring the normal passage of water and improving the drying efficiency; and, because the dredging rod 15 is in the cavity formed by the concave plate 12 and the drying frame 7 when working, the concave plate 12 will also use its edge to push the plastic particles when moving, so that the dredging rod 15 will not squeeze the plastic particles out of the through hole 23 when passing through the through hole 23, ensuring that the plastic particles can be continuously above the water filter plate 10 without being disturbed by the dredging rod 15; when the dredging rod 15 passes through the through hole 23, its end will also be stained with impurities, and when the dredging rod 15 is reset, these impurities may fall into the inner cavity of the concave plate 12. When the impurities accumulate in the concave plate 12, When there are too many cavities in the profile plate 12, the operation of the components in the cavity of the concave plate 12 will be affected. Therefore, when the concave plate 12 moves laterally, the scraper 24 will also move laterally under the action of the motor 5 26 driving the threaded rod 4 25 to rotate. When the dredging rod 15 passes through the water filter plate 10 and the lower end surface of the dredging rod 15 is flush with the lower end surface of the water filter plate 10, the upper end of the scraper 24 will form a scraping with the bottom of the dredging rod 15 to scrape off the impurities attached to the bottom of the dredging rod 15, thereby realizing the self-cleaning of the impurities attached to the bottom of the dredging rod 15, and avoiding the impurities falling into the cavity of the concave plate 12 again when the dredging rod 15 is reset, thereby affecting the operation of the components in the cavity of the concave plate 12.When the concave plate 12 moves horizontally to the left and right, the concave plate 12 will push the plastic particles in one direction. When the plastic particles are pushed in one direction, accumulation will occur. When the plastic particles are accumulated, the plastic particles at the bottom will not be dried evenly. Therefore, when the concave plate 12 moves horizontally, the angle between the paddle plate 13 on one side of the moving direction of the concave plate 12 and the end surface of one side of the concave plate 12 is ninety degrees, and the paddle plate 13 on the other side is parallel to the end surface of one side of the concave plate 12. When the plastic particles accumulate on one side of the concave plate 12, the motor 3 21 drives the threaded rod 2 16 to rotate, so that the slide plate 14 moves from bottom to top, so as to use the paddle plate 13 to push the plastic particles until the paddle plate 1 3 moves to the top, and then the motor 22 drives the paddle plate 13 to rotate to push the plastic particles in the opposite direction of the moving direction, so that the plastic particles can fall to the other side of the concave plate 12, and then repeat the above action, the accumulated plastic particles can be lifted and pushed to the other side of the concave plate 12 during the lateral movement of the concave plate 12, thereby avoiding the situation that when the concave plate 12 moves horizontally, the concave plate 12 pushes the plastic particles in one direction, thereby causing the plastic particles to accumulate and the plastic particles at the bottom cannot be dried evenly, and the push of the paddle plate 13 can further promote the scattering of the plastic particles, which is beneficial to increase the wind receiving area of ​​the plastic particles and further improve the drying efficiency. ;
