Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to a rapid drying device for plastic particles. Background Technology

[0002] A rapid drying device for plastic particles is a piece of equipment specifically designed for plastic particles. Its core function is to effectively remove moisture or other volatile substances contained in plastic particles in a short time through specific technical means, so as to meet the requirements of raw material dryness in plastic processing (such as injection molding, etc.).

[0003] A search revealed Chinese patent application CN202222150950.5, which proposes a rapid drying device for plastic particles. The device includes a drying chamber and a hot air blower. The top of the drying chamber has symmetrically arranged feeding ports. An internal support mechanism, including a support frame and a connecting rotating rod, is located inside the drying chamber. A plastic particle ventilation drying cylinder is installed inside the drying chamber. A ventilation pipe is externally sealed to the hot air blower, and air distribution pipes are fixed to both sides of the ventilation pipe. The end of the air distribution pipe furthest from the ventilation pipe penetrates the interior of the drying chamber. This design, through the combined arrangement of the drying chamber, support frame, connecting rotating rod, and plastic particle ventilation drying cylinder, allows the plastic particle ventilation drying cylinder to quickly expel internal water stains as the connecting rotating rod moves, thereby accelerating moisture removal and increasing the drying speed of the plastic particles. The movement of the plastic particle ventilation drying cylinder also promotes the movement of the internal plastic particles, preventing prolonged accumulation and clumping. The drying chamber provides external protection to prevent water splashing.

[0004] In the aforementioned prior art, the drying process mainly involves using a drying and ventilation device installed at the top to dry the support structure inside the drying chamber. Although this method has a certain drying effect, the drying and ventilation is done by blowing hot air into the drying chamber through pipes, resulting in a small area of ​​hot air blowing. Drying is mainly achieved through the automatic dispersion of hot air, which leads to low drying efficiency. Utility Model Content

A toothed ring 22 is fixedly connected to the outer side of the upper end of the filter screen rotating cylinder 21, and a shell 23 is rotatably sleeved on the outer side of the toothed ring 22. The lower end of the shell 23 is rotatably connected to the drying barrel 1. A motor 24 is inserted into the inner side of one end of the drying barrel 1. The lower end of the motor 24 is fixedly connected to the drying barrel 1, and a gear 25 is fixedly connected to the output shaft of the motor 24. One end of the gear 25 is meshed with the gear ring 22. An air intake component 3 is provided on the outer side of one end of the drying barrel 1. A blower component 4 is provided on the inner side of the end of the air intake component 3 away from the drying barrel 1, and a heating component 5 is provided on one end of the blower component 4. An air guide component 6 is provided on the inner side of the end of the drying barrel 1 close to the air intake component 3, and a flow guide component 7 is provided on the inner side of one end of the drying barrel 1. An exhaust component 8 is provided on the inner side of the end of the drying barrel 1 close to the flow guide component 7. By cooperating with the rotating component 2 and the air intake component 3, the drying area can be increased, thereby effectively improving the drying efficiency of the plastic particles inside the drying barrel 1 and thus increasing the drying speed.

[0020] like Figure 1 As shown, the air intake assembly 3 includes a protective cover 31 fixedly connected to the outer side of one end of the drying barrel 1, and a first filter screen 32 is inserted inside the end of the protective cover 31 away from the drying barrel 1. The first filter screen 32 has a first fastening bolt 33 threadedly engaged at both ends, and the first fastening bolt 33 is threadedly engaged inside the protective cover 31 at the end near the protective cover 31.

[0021] like Figure 3 As shown, the blower assembly 4 includes a first bracket 41 fixedly connected to the inner side of the protective cover 31 away from the drying barrel 1, and multiple sets of fans 42 are fixedly connected to the outer side of the middle end of the first bracket 41. After the fans 42 are started, the air inside the protective cover 31 flows to form an airflow. After the airflow flows, the outside air enters the protective cover 31 through the filtration of the first filter screen 32.

[0022] like Figure 3 As shown, the heating assembly 5 includes a heating plate 51 fixedly connected to the inner side of the protective cover 31 near the drying barrel 1, and a power supply 52 is electrically connected to the upper end of the heating plate 51. The lower side of the power supply 52 is fixedly connected to the protective cover 31. The operation of the heating plate 51 is controlled by the power supply 52 so as to heat the passing airflow.

[0023] like Figure 3As shown, the air guide assembly 6 includes a baffle 61 fixedly connected to the inner side of the drying barrel 1 near the protective cover 31, and a high-temperature resistant plate 62 fixedly connected to the baffle 61 near the protective cover 31. The airflow is guided by the baffle 61 and the high-temperature resistant plate 62, and the guided airflow enters the interior of the drying barrel 1 and rotates along the outer end of the drying barrel 1.

[0024] like Figure 4 As shown, the flow guiding assembly 7 includes a second bracket 71 fixedly connected to the inner side of the drying barrel 1 away from the control box 13, and a flow guiding plate 72 fixedly connected to the second bracket 71 away from the drying barrel 1. When the airflow reaches the flow guiding plate 72 after rotating once inside the drying barrel 1, a portion of it passes through the flow guiding plate 72 and is discharged from the second filter screen 81 under the support of the second bracket 71.

[0025] like Figure 4 As shown, the exhaust assembly 8 includes a second filter screen 81 inserted into the inner side of the drying barrel 1 near the second bracket 71, and the two ends of the second filter screen 81 are threaded with second fastening bolts 82. The second fastening bolts 82 are threaded into the drying barrel 1 at the end near the drying barrel 1. The airflow in the drying barrel 1 is discharged from the drying barrel 1 through the second filter screen 81. The second filter screen 81 can be removed by unscrewing the second fastening bolts 82.

[0026] Working principle: When drying plastic particles, the plastic particles to be dried are first injected into the filter drum 21 through the feed inlet 11. Then, under the support of the protective cover 31 and the first bracket 41, the fan 42 is started. After the fan 42 starts, the air inside the protective cover 31 flows to form an airflow. After the airflow flows, the outside air enters the protective cover 31 through the filtration of the first filter 32. Then, the airflow is guided by the baffle 61 and the high-temperature resistant plate 62. The guided airflow enters the drying drum 1 and rotates along the outer end of the drying drum 1. Then, under the protection of the outer shell 23, the motor 24 is started. After the motor 24 starts, the output shaft drives the gear 25 to rotate, so that the gear 25 meshes with the gear ring 22, causing the gear ring 22 to drive the filter drum 21 to rotate. After the filter drum 21 rotates, the water attached to the surface of the plastic particles inside is thrown out, thus cooperating with the airflow to dry the filter drum 21. The plastic particles inside the drying drum 1 are dried. At the same time, the heating plate 51 is controlled by the power supply 52 to heat the airflow. After the airflow rotates once inside the drying drum 1, it reaches the guide plate 72. With the support of the second bracket 71, part of the airflow passes through the guide plate 72 and is discharged from the second filter screen 81, while the other part passes over the guide plate 72 and the baffle 61 and mixes with the airflow that enters later. This continuously dries the plastic particles inside the filter screen drum 21. The water thrown out by the rotating filter screen drum 21 is discharged through the water outlet 14. After drying, the discharge port 12 can be opened to discharge the dried plastic particles from the drying drum 1. Then, the first fastening bolt 33 can be unscrewed to remove the first filter screen 32, and the second filter screen 81 can be unscrewed to remove the second fastening bolt 82, so as to clean and replace the first filter screen 32 and the second filter screen 81.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
