Description

Technical Field

[0001] This utility model belongs to the field of plastic particle drying technology, and specifically relates to a plastic particle dryer. Background Technology

[0002] Plastic pellets are a common name for plastic granules. They are raw materials for storing, transporting, and processing plastics in a semi-finished form. Plastics are a type of polymer material, and plastic materials often need to undergo drying pretreatment before further molding.

[0003] Most existing plastic particle dryers dry plastic particles by blowing hot air into the lower part of the machine through pipes. The hot air diffuses from bottom to top and from point to surface. Since the plastic particles are in a relatively static state and the gaps between them are small, the upward flow of hot air is subject to great resistance, which not only causes uneven drying but also results in a long drying time.

[0004] Therefore, a plastic particle dryer is proposed. Summary of the Invention

[0005] This invention provides a plastic particle dryer, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides a plastic particle dryer, including a drying cylinder; an outer edge of the cylinder located near the top of the outer wall of the drying cylinder; an electric push rod located at the top of the outer edge of the cylinder; a lifting ring fixed to the output end of the electric push rod; a plurality of electromagnetic blocks axially and equally spaced on the inner wall of the lifting ring; a hollow sphere located inside the drying cylinder; an iron ring located on the outer wall of the hollow sphere; an air outlet located on the outer wall of the hollow sphere near the outer side of the iron ring; an air inlet pipe located on the outer wall of the drying cylinder; and a corrugated hose located on the inner wall of the drying cylinder near the air inlet pipe, with one end of the corrugated hose rotatably connected to the bottom of the hollow sphere.

[0007] Furthermore, an air inlet pipe is provided on the outer wall of the drying cylinder near the lower part of the first air inlet pipe, and a cylinder cover is provided on the top of the drying cylinder, with an exhaust pipe provided on the top of the cylinder cover.

[0008] Furthermore, the drying cylinder is made of non-magnetic heat-resistant plastic, and a discharge valve is provided at the bottom of the drying cylinder;

[0009] By adopting the above technical solution, the non-magnetic drying cylinder can avoid the electromagnetic block and the drying cylinder from attracting each other, and the drying of plastic particles inside the drying cylinder can be achieved by utilizing its own heat resistance.

[0010] Furthermore, one outer wall of the electromagnetic block is attached to the outer wall of the drying cylinder, and the electromagnetic block generates magnetism after being energized. The electromagnetic block and the iron ring are connected by magnetic attraction.

[0011] By adopting the above technical solution, the electromagnetic block is attracted to the iron ring by magnetic attraction, and the iron ring is moved axially along the inner wall of the drying cylinder by the cyclic switching of several electromagnetic blocks, thereby causing the hollow ball to move inside the drying cylinder.

[0012] Furthermore, both the hollow sphere and the air intake pipe are connected to a corrugated hose;

[0013] By adopting the above technical solution, hot air is ensured to flow and circulate inside the air inlet pipe and the corrugated hose, thereby allowing the hot air to enter the hollow sphere and be ejected from all directions through the air outlet on the hollow sphere.

[0014] Furthermore, both the exhaust pipe and the intake pipe are connected to the drying cylinder;

[0015] By adopting the above technical solution, hot air can be guaranteed to enter and exit the drying cylinder.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention utilizes controllable magnetic adsorption to enable hollow spheres to move horizontally and vertically within the drying cylinder. This movement not only disturbs the tightly packed plastic particles, increasing the gaps between them and facilitating the entry and flow of hot air while reducing airflow resistance, but also ensures that the hot air ejected from the hollow spheres contacts the plastic particles at different horizontal and vertical positions within the drying cylinder more evenly. This guarantees uniform and thorough drying of the plastic particles and avoids heat loss caused by the upward flow of hot air, thus improving the drying effect and efficiency.

[0018] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Reference Figure 1-4This utility model provides a plastic particle dryer, including a drying cylinder 1. An outer edge 2 is located near the top of the outer wall of the drying cylinder 1. Three electric push rods 3 are axially and evenly spaced at the top of the outer edge 2. A lifting ring 4 is fixedly connected to one output end of each of the three electric push rods 3. A plurality of electromagnetic blocks 5 are axially and evenly spaced on the inner wall of the lifting ring 4. A hollow sphere 6 is located inside the drying cylinder 1. An iron ring 7 is located near the middle of the outer wall of the hollow sphere 6. One outer wall of each electromagnetic block 5 is in contact with the outer wall of the drying cylinder 1, and the electromagnetic block 5 generates magnetism when energized. The electromagnetic block 5 and the iron ring 7 are magnetically attracted together. The magnetic attraction force causes the electromagnetic block 5 to attract the iron ring 7. By cyclically switching the energized electromagnetic blocks 5 on and off, the iron ring 7 moves axially along the inner wall of the drying cylinder 1, thereby causing the hollow sphere 6 to move axially within the drying cylinder. The internal movement of the drying cylinder 1 is as follows: an air outlet 8 is provided on the outer wall of the hollow sphere 6 near the outer side of the iron ring 7; an air inlet pipe 9 is provided on one side of the outer wall of the drying cylinder 1; and a corrugated hose 10 is provided on one side of the inner wall of the drying cylinder 1 near one end of the air inlet pipe 9. The hollow sphere 6 and the air inlet pipe 9 are connected to the corrugated hose 10 to ensure that hot air flows inside the air inlet pipe 9 and the corrugated hose 10, thereby allowing hot air to enter the hollow sphere 6 and be sprayed out in all directions through the air outlet 8 on the hollow sphere 6. One end of the corrugated hose 10 is rotatably connected to the bottom of the hollow sphere 6. The drying cylinder 1 is made of non-magnetic heat-resistant plastic cylinder, and a discharge valve is provided at the bottom of the drying cylinder 1. By using the non-magnetic drying cylinder 1, the electromagnetic block 5 can be prevented from attracting each other to the drying cylinder 1, and the heat resistance of the cylinder itself can be used to dry the plastic particles inside the drying cylinder 1.

[0027] An air inlet pipe 11 is provided on the outer wall of the drying cylinder 1 near the lower part of the first air inlet pipe 9, and a cylinder cover 12 is provided on the top of the drying cylinder 1. An exhaust pipe 13 is provided on the top of the cylinder cover 12. Both the exhaust pipe 13 and the second air inlet pipe 11 are connected to the drying cylinder 1 to ensure that hot air enters and exits the drying cylinder 1. Hot air enters at one end of both the first air inlet pipe 9 and the second air inlet pipe 11. The hot air is drawn by an external air pump and heated by an external heating wire. The plastic particles inside the drying cylinder 1 are dried by the hot air.

[0028] The specific implementation method is as follows: When drying plastic particles, the plastic particles are filled inside the drying cylinder 1, the cylinder cover 12 is closed, and hot air is pumped into the corrugated hose 10 and the drying cylinder 1 through the first air inlet pipe 9 and the second air inlet pipe 11 in sequence. With the corrugated hose 10 connected, the hot air enters the interior of the hollow sphere 6 and is sprayed out to the surroundings through the air outlet 8 on the outer wall of the hollow sphere 6. The hot air is dried by contacting the plastic particles inside the drying cylinder 1.

[0029] During the drying process, several electromagnetic blocks 5, which are axially distributed on the control lifting ring 4, are turned on and off in sequence. Through the magnetic attraction between the electromagnetic blocks 5 and the iron ring 7, a magnetic force is generated to attract the iron ring 7 to move axially along the inner wall of the drying cylinder 1. The hollow ball 6 moves synchronously and changes its horizontal position inside the drying cylinder 1. While disturbing the plastic particles inside the drying cylinder 1, the hollow ball 6 allows the hot air to contact the plastic particles more evenly, so that the hot air can fully enter the gaps between the plastic particles and improve the drying efficiency of the plastic particles.

[0030] After the hollow ball 6 moves axially along the inner wall of the drying cylinder 1, the electric push rod 3 drives the lifting ring 4 to move upward through its output end on one side. As the lifting ring 4 moves upward, the adsorbed hollow ball 6 moves upward synchronously. This allows the plastic particles at different heights inside the drying cylinder 1 to be dried, achieving thorough drying.

[0031] During the drying process, the air containing moisture is discharged through the exhaust pipe 13.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
