Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic production, in particular to a high-efficiency drying machine for plastic particles. Background Art
[0002] Plastic particles are the common name for plastic particles. They are the raw materials for storing, transporting and processing plastics in the form of semi-finished products. Plastics are a type of polymer material. Ethylene, propylene, vinyl chloride, styrene, etc. can be produced from petroleum. Under certain conditions, the molecules of these substances can react with each other to form compounds with large molecular weights. When plastic materials are processed in the next step, they often need to be dried first.
[0003] At present, most of the existing plastic particle dryers dry the plastic particles by blowing hot air into the lower part of the drying cylinder through a pipeline, forming a gradient distribution of hot air from bottom to top, temperature from high to low, and humidity from low to high, so that the lower plastic particles are dried first, forming a continuous drying and feeding process with the lower part discharging and the upper part feeding. However, due to the large capacity of the equipment, the plastic particles are in a relatively static state before drying and feeding, resulting in a long drying time. Since the blown hot air diffuses from point to surface and from bottom to top, the resistance is large, the temperature distribution is uneven, and the uniformity of the drying quality is not high. Plastic particles with high moisture content near the hot air pipeline or outlet are prone to agglomeration, resulting in poor feeding. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figure 1-4 The utility model provides a technical solution: a high-efficiency dryer for plastic particles, including a shell 1, a feed port 2, a motor 3, a sieve plate 4, a fan 5, a motor 6, a guide plate 7, a ventilation fan 8, a guide plate 9, a sliding groove 10, a spring 11, an air bag 12, a support tube 13, an air pipe 14, a fan 15, a gear 16, a tooth chain 17, and a discharge port 18.
[0027] The plastic particle high-efficiency dryer is provided with a screening plate 4, which can prevent the plastic particles from accumulating and agglomerating at the feed inlet 2, specifically:
[0028] A feed port 2 is installed through the upper surface of the housing 1, a motor 3 is installed on the upper surface of the inner wall of the housing 1, and a sieve plate 4 is connected to the lower surface of the motor 3, a fan 5 is fixedly installed on the lower surface of the sieve plate 4, the sieve plate 4 is set in a circular shape, and a fan-shaped hole is opened on the surface of the sieve plate 4, and the part of the surface of the sieve plate 4 without the fan-shaped hole is set in a convex arc shape;
[0029] The high-efficiency dryer for plastic particles is used for drying plastic particles. First, the motor 1 3 arranged on the upper surface and the side surface of the inner wall of the shell 1 is turned on, and the motor 2 6 is turned on. Then, the plastic particles are put in from the feed port 2. The plastic particles fall to the sieve plate 4 through the feed port 2. At this time, the sieve plate 4 starts to rotate. Since the surface of the sieve plate 4 is provided with fan-shaped holes, the plastic particles fall downward from the fan-shaped holes under the rotation of the sieve plate 4. Due to the rotation of the sieve plate 4, the plastic particles will not accumulate and can fall downward evenly. A fan 2 15 is arranged above the sieve plate 4. The fan 2 15 rotates, and the air flow blows the particles on the sieve plate 4 through the air inlet on the side surface of the shell 1, so as to preliminarily dry the plastic particles and prevent the plastic particles from agglomerating.
[0030] The plastic particle high-efficiency dryer cools the plastic particles quickly and efficiently through the cooperation of the fan 15, the guide plate 1 7 and the guide plate 2 9, specifically:
[0031] A motor 26 is installed on the side interlayer of the shell 1, and the motor 26 is connected to a guide plate 17, one end of the guide plate 17 is fixedly installed on the inner wall side surface of the shell 1, and a ventilation fan 8 is connected to the side surface of the motor 26. A guide plate 29 is arranged below the guide plate 17, and three springs 11 are installed at equal intervals on the lower surface of the upper end of the guide plate 29, and the spring 11 is installed inside the sliding groove 10, and the guide plate 29 is slidably installed inside the sliding groove 10, and the sliding groove 10 is installed on the inner wall side surface of the shell 1, and an air bag 12 is installed on the lower surface of the other end of the guide plate 29, and the lower end of the air bag 12 is installed on the upper surface of the support tube 13, and an air pipe 14 is installed inside the support tube 13, one end of the air pipe 14 is connected to the lower surface of the air bag 12, and the other end of the air pipe 14 passes through the side surface of the sliding groove 10. A fan 2 15 is installed at a corresponding position below the sliding groove 10, and the other end of the fan 2 15 passes through the inner wall side surface of the shell 1 and the interlayer, and a gear 16 is installed at this end of the fan 2 15, and the gear 16 is meshed with a toothed chain 17, and the upper end of the toothed chain 17 is also meshed with a gear 16. A discharge port 18 is installed on the lower surface of the shell 1, and the guide plate 1 7 and the guide plate 2 9 are both set to a downward inclined state, and the guide plate 1 7 and the guide plate 2 9 are both provided with electric heating wires. The opening of the sliding groove 10 is inlaid with the guide plate 2 9 and the spring 11, and the air pipe 14 passes through the inside of the support tube 13 and extends upward to the side surface of the sliding groove 10. There are three support tubes 13, and the lower surface of the shell 1 is connected to the discharge port 18, and the lower surface of the shell 1 is in an inclined state toward the discharge port 18.
[0032] When the particles continue to fall downward and reach the guide plate 7, a heating wire is arranged inside the guide plate 7, so the plastic particles are dried by heat on the guide plate 7, and a fan 5 is installed on the lower surface of the sifting plate 4. Driven by the sifting plate 4, the fan 5 also starts to rotate, so that the fan 5 drives the airflow blown in by the fan 2 15 to blow downward, and at the same time, the plastic particles are also dried, and the air above the guide plate 7 flows to make the internal heat uniform. Then the plastic particles continue to fall downward onto the guide plate 2 9, and the guide plate 2 9 slides downward under the gravity of the plastic particles. A spring 11 is installed on the lower surface of the upper end of the guide plate 2 9, so under the action of the spring 11, the guide plate 2 9 slides upward, and the upper end of the guide plate 2 9 is embedded in the sliding groove 10, which can play a role in the guide plate 2 9 The limiting effect is to prevent the guide plate 29 from sliding off. An air bag 12 is installed at the lower end of the guide plate 29. When the guide plate 29 is downward, the air bag 12 is pressed at the same time, so that the air flow flows through the air pipe 14 installed inside the support tube 13, and the air flow is ejected from the top of the guide plate 29. The air flow above the guide plate 29 can achieve a better drying effect on the plastic particles. A fan 2 15 is arranged below the sliding groove 10. The fan 2 15 is connected to the fan 2 15 arranged above the sieve plate 4 through a tooth chain 17, so the fan 2 15 starts to rotate and blows the air below the guide plate 29 to avoid heat accumulation. At this time, the ventilation fan 8 on the inner wall side surface of the outer shell 1 discharges the hot steam inside the dryer to the outside to keep the inside dry, and then the plastic particles fall down to the bottom of the outer shell 1 and are discharged through the discharge port 18.
[0033] Working principle: When using the high-efficiency plastic particle dryer, the sieve plate 4 is used to prevent the particles from piling up and agglomerating, and the internal air circulates under the action of the fan 1 5 and the fan 2 15, so that the internal temperature is uniform, thereby increasing the overall practicality.
[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
