Description

Technical Field

[0001] The utility model relates to the field of plastic particle drying, in particular to plastic particle drying equipment with a vertical air flow track. Background Art

[0002] Plastic pellet drying equipment is a kind of equipment specially used to remove moisture from plastic pellets. During the production process, plastic pellets may contain a certain amount of moisture due to various reasons. This moisture may not only affect the processing performance and product quality of plastic pellets, but also cause damage to production equipment. Therefore, using plastic pellet drying equipment to dry plastic pellets is an important part of ensuring the quality of plastic products and production efficiency.

[0003] A Chinese patent with publication number CN108582569B discloses a comprehensive drying device for plastic particles, including a dryer shell, a video monitoring device and a controller. A water collecting tank is arranged on one side of the dryer shell. When water vapor meets the cold large hollow disc and small hollow disc, condensed water will be generated, thereby causing accumulated water in the large hollow disc and the small hollow disc. It is not ruled out that the accumulated water will affect the normal passage of steam, thereby affecting the thermal conductivity of the bottom of the large hollow disc and the small hollow disc. The accumulated water generated by condensation is introduced into the water collecting tank for collection, and the accumulated water can be pumped to the nozzle by a water pump at a later stage for spraying, thereby cleaning the internal facilities of the dryer shell, which not only solves the problem of accumulated water affecting thermal conductivity, but also realizes the reuse of wastewater.

[0004] The comprehensive drying equipment for plastic particles in the above patent cannot provide a smooth gas flow trajectory during the drying process. The unstable gas flow trajectory reduces the drying efficiency of the plastic particles, affecting the subsequent processing and use of the plastic particles. Utility Model Content

[0005] The purpose of the utility model is to provide a plastic particle drying device with a vertical air flow trajectory. The restriction of the restriction bar can make the drying frame in a rotating state drive the internal particles to rotate, and the rotation makes the plastic particles accumulate in the recessed cavity. The accumulation is convenient for the liquid to be thrown out and the plastic particles to be dried. In addition, the high-temperature gas is vertically guided through the transmission pipe to provide a vertical air flow trajectory, thereby improving the drying efficiency of the plastic particles and solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present utility model provides the following technical solution: A plastic particle drying device with a vertical air flow trajectory, including a housing. One side of the lower end inside the housing is provided with a heating fan. In the middle of the housing is provided a drying frame. A transmission cavity is circumferentially arranged at the upper end of the drying frame. A transmission ring is arranged inside the transmission cavity. A connecting ring is circumferentially arranged inside the transmission ring, and the outer part of the connecting ring is rotationally connected to the internal rotation slot of the housing. Inside the drying frame, limiting strips are evenly distributed circumferentially. A transmission pipe is longitudinally arranged inside the limiting strips. The lower ends of the circumferentially distributed transmission pipes penetrate through the drying frame and extend to the lower end outside the drying frame.

[0007] Preferably, the limiting strips are fixedly welded to the lower end inside the drying frame. A concave cavity is arranged between two adjacent limiting strips. A drainage filter screen is arranged at the position of the concave cavity inside the drying frame.

[0008] Preferably, the lower ends of the circumferentially distributed drying frames are hermetically connected through a connecting pipe. The middle position of the lower end of the connecting pipe is rotationally connected to the air outlet position of the heating fan.

One side of the lower end of the liquid storage frame is hermetically connected to the upper end of the liquid extraction pump.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The present utility model extracts external gas through a heating fan, heats it and then transmits it. It flows through the connecting pipe and the transmission pipe to the inside of the drying frame. During the rotation of the drying frame, the high-temperature gas is discharged from the first exhaust pipe and the second exhaust pipe connected to the transmission pipe.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] In order to solve the problem that the existing comprehensive drying equipment for plastic particles cannot provide a smooth gas flow trajectory during the drying process, and the non-fixed gas flow trajectory causes a decrease in the drying efficiency of plastic particles, affecting the subsequent processing and use of plastic particles, the following technical solutions are provided in this embodiment:

[0023] A plastic particle drying equipment with a vertical air flow trajectory, including an outer shell 1. On one side of the lower end inside the outer shell 1, a heating fan 2 is provided. Through the heating fan 2, external gas can be extracted and the gas can be heated and transported to the inside of the drying frame 10. On the other side of the lower end inside the outer shell 1, a liquid extraction pump 3 is provided. The liquid extraction pump 3 can extract the liquid accumulated and thrown out at the lower end inside the liquid storage frame 6, and actively extract the liquid inside the liquid storage frame 6 to avoid the liquid accumulation affecting the rotation of the drying frame 10 and the drying of plastic particles. For exampleFigure 1 As shown, a drying frame 10 is provided in the middle inside the housing 1, and the plastic particles to be dried can be directly put into the inside of the drying frame 10;

[0024] In this embodiment, a baffle 4 is provided at the upper end outside the drying frame 10, and the front and rear ends on one side of the baffle 4 are respectively rotatably connected to the upper end of the housing 1, as Figure 1 and Figure 2 shown, the rotation of the baffle 4 can wrap or expose the upper end of the drying frame 10;

[0025] In this embodiment, limiting strips 11 are evenly distributed around the inside of the drying frame 10, and the limiting strips 11 are welded and fixed to the lower end inside the drying frame 10, as Figure 2 and Figure 4 shown, a concave cavity 18 is provided between two adjacent limiting strips 11. During the rotation of the drying frame 10, the plastic particles will move and accumulate towards the periphery of the drying frame 10. During the accumulation process, due to the limitation of the limiting strips 11, the plastic can stay inside the concave cavity 18. A drainage filter screen is provided at the position of the concave cavity 18 inside the drying frame 10, and the liquid on the surface of the plastic particles will be directly thrown out, so that the liquid can be discharged from the filter screen at the position of the concave cavity 18;

[0026] In this embodiment, a transmission pipe 12 is longitudinally provided inside the limiting strip 11. The lower ends of the surrounding transmission pipes 12 penetrate through the drying frame 10 and extend to the lower end outside the drying frame 10. The lower ends of the surrounding drying frames 10 are hermetically connected through a connecting pipe 13, as Figure 1 and Figure 2 shown, the external gas can be transmitted towards the inside of the drying frame 10 after being heated by the heating fan 2 and transmitted through the connecting pipe 13 and the transmission pipe 12;

[0027] In this embodiment, first exhaust pipes 16 are provided on both sides outside the transmission pipe 12 and penetrate through the limiting strip 11, as Figure 4 、 Figure 5 and Figure 6 shown, second exhaust pipes 17 are provided on both sides of the transmission pipe 12 facing the middle position of the drying frame 10 and penetrate through the limiting strip 11. After the high-temperature gas is transmitted through the transmission pipe 12, it can be discharged from the first exhaust pipes 16 and the second exhaust pipes 17, actively making the high-temperature gas move towards the concave cavity 18. The first exhaust pipes 16 and the second exhaust pipes 17 are aligned with the concave cavity 18. Through the first exhaust pipes 16 and the second exhaust pipes 17 aligned with the concave cavity 18, the high temperature can directly contact the plastic particles accumulated in the concave cavity 18;

[0028] In this embodiment, a transmission cavity 9 is disposed around the upper end of the drying frame 10. A transmission ring 8 is arranged inside the transmission cavity 9. Tooth grooves 14 are disposed around the outside of the transmission ring 8, and the tooth grooves 14, the transmission ring 8, and the drying frame 10 are fixedly welded in sequence. As shown in Figure 2 , Figure 3 and Figure 4 shown, on one side outside the tooth grooves 14, a gear 15 is provided, and the outside of the gear 15 is meshed and connected with the outside of the tooth grooves 14. By rotating the gear 15, the drying frame 10 can be driven to rotate through the tooth grooves 14, so that the drying frame 10 drives the plastic particles inside to rotate, realizing the centrifugal dehydration of the plastic particles.

[0029] In this embodiment, the middle position at the lower end of the connecting pipe 13 is rotatably connected to the air outlet position of the heating fan 2. As shown in Figure 2 shown, the rotation of the drying frame 10 can drive the connecting pipe 13 to rotate through the transmission pipe 12. The rotation of the connecting pipe 13 above the heating fan 2 will not prevent the heating fan 2 from transmitting high-temperature gas. At the upper end of the center of the gear 15, a motor 5 for output is provided, and the output shaft of the motor 5 can directly drive the gear 15 to rotate, so that the rotation of the gear 15 can drive the drying frame 10 to rotate.

[0030] In this embodiment, as shown in Figure 2 shown, a connecting ring 7 is disposed around the inside of the transmission ring 8, and the outside of the connecting ring 7 is rotatably connected to the internal rotation slot of the housing 1. Through the rotation slot connection, the connecting ring 7 can be embedded into the inside of the housing 1. By rotating the connecting ring 7 inside the housing 1, the drying frame 10 can be suspended inside the housing 1 and tightly rotated.

[0031] In this embodiment, a liquid storage frame 6 is disposed around the outside of the drying frame 10, and the upper end of the liquid storage frame 6 is fixedly welded to the lower end inside the housing 1. One side at the lower end of the liquid storage frame 6 is hermetically connected to the upper end of the liquid extraction pump 3. As shown in Figure 1 and Figure 2 shown, the rotation of the drying frame 10 can throw out the liquid, and the liquid can be stored inside the liquid storage frame 6, stored inside the liquid storage frame 6 and extracted and discharged by the liquid extraction pump 3.

[0032] Working principle: When using the device to dry the plastic particles put into the device interior, the plastic particles to be dried are put into the interior of the drying frame 10 from the position wrapped by the baffle 4. After putting them in, start the motor 5. The start of the motor 5 can drive the gear 15 to rotate. The rotation of the gear 15 drives the transmission ring 8 to rotate through the tooth groove 14. The rotation of the transmission ring 8 is restricted by the connecting ring 7 in the housing 1, which enables the drying frame 10 to rotate in the liquid storage frame 6. The rotation of the drying frame 10 can drive the plastic particles inside to accumulate at the concave cavities 18 on both outer sides of the limiting strip 11. Start the heating blower 2. The heating blower 2 can extract the external gas and heat and transport the gas into the connecting pipe 13. The gas in the connecting pipe 13 is shunted and transported to the inside of the limiting strip 11 through the transmission pipe 12. The transmission pipe 12 inside the limiting strip 11 is again shunted and transported to the concave cavity 18 through the first exhaust pipe 16 and the second exhaust pipe 17, so that the high-temperature gas can directly contact the plastic particles accumulated in the concave cavity 18. The liquid thrown out by the drying frame 10 will flow into the interior of the liquid storage frame 6, and the liquid flowing into the interior of the liquid storage frame 6 will be extracted and discharged by the liquid extraction pump 3.
