Description

Technical Field

[0001] The present application relates to the technical field of drying equipment, and in particular to a rapid drying device for plastic particles. Background Art

[0002] With the rapid development of the plastics industry, plastic particles are the basic raw materials for the production of plastic products. Their quality and processing efficiency directly affect the performance and production cost of the final product. During the production process, plastic particles often contain a high amount of moisture, which not only reduces their processing performance, but may also cause problems such as bubbles and cracks in the products. Therefore, effective drying of plastic particles is an indispensable part of the production of plastic products.

[0003] In the prior art, during the drying process, plastic particles of different diameters and sizes may exist, and the ratio of the surface area to volume of particles of different diameters is different, resulting in smaller particles drying faster and larger particles drying slower; resulting in uneven final drying effect, small particles may be over-dried, and large particles may still contain more moisture; in order to ensure that all particles can reach the required dryness level, the drying time may need to be extended, which will increase energy consumption and costs. Summary of the invention

[0063] like Figure 2 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown, the discharging assembly 85 includes a sealing plate four 851, which is in the shape of a circular plate. The sealing plate four 851 slides vertically on the bottom of the bracket 4, and a plurality of through holes four 852 are provided at the top of the bracket 4 corresponding to the inner cavities of the drying box one 81, the drying box two 82 and the drying box three 83. The through holes four 852 extend in the vertical direction, and a sealing plug 853 is vertically inserted in the through holes four 852. The bottom end of the sealing plug 853 is fixedly arranged on the top of the sealing plate four 851; driving parts for driving the sealing plate four 851 to move are provided on the opposite sides of the bracket 4, and the sealing plate four 851 is provided with a plurality of through holes five 854 along the vertical direction.

[0064] like Figure 2 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown, during the operation of each drying box, each sealing plug 853 is inserted into each through hole four 852, and each drying box is in a sealed state. When the plastic particles in each drying box are dried, the staff can drive the sealing plate four 851 away from the top of the bracket 4 through the driving member, and the sealing plate four 851 can simultaneously drive each sealing plug 853 away from each through hole four 852. At this time, the dried plastic particles in each drying box can be discharged through each through hole four 852, thereby reducing the difficulty of discharging the plastic particles; the set through hole five 854 can speed up the discharge of the plastic particles.

[0065] like Figure 2 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7As shown, the driving member is a cylinder 11, which is installed on the side wall of the bracket 4, and the piston rod on the cylinder 11 is vertically arranged, and two connecting rods 12 are fixedly arranged on the side wall of the sealing plate 4 851, and a fixing block 13 is fixedly arranged at the bottom end of the piston rod of the cylinder 11, and the connecting rod 12 is penetrated and rotatably connected in the fixing block 13, and a torsion spring 14 is sleeved on the connecting rod 12, and the two ends of the torsion spring 14 are respectively fixedly connected to the fixing block 13 and the connecting rod 12; a gear 7 15 is sleeved and fixed on the connecting rod 12, and racks 2 16 are vertically fixedly arranged on the opposite side walls of the bracket 4, and the gear 7 15 is meshed with the racks 2 16.

[0066] like Figure 2 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown, the staff first turns on the cylinder 11, and the piston on the cylinder 11 can drive the connecting rod 12 and the sealing plate 4 851 to move away from the top of the bracket 4; when the sealing plate 4 851 drives the sealing plug 853 to move to a position away from the through hole 4 852, the rack 2 16 can drive the gear 7 15 to rotate, and the gear 7 15 can drive the connecting rod 12 and the sealing plate 4 851 to rotate, and the torsion spring 14 is twisted until the sealing plate 4 851 rotates to a tilted state. At this time, the plastic particles remaining on the sealing plate 4 851 can slide down under the action of their own gravity, thereby reducing the plastic particles remaining on the sealing plate 4 851 and facilitating sealing. Plug 853 blocks the through hole four 852 again; thereafter, when the plastic particles in each drying box have completely flowed out, the cylinder 11 can again drive the sealing plate four 851 to drive the sealing plug 853 to move toward the through hole four 852. At this time, the rack two 16 can drive the gear seven 15 to rotate in the opposite direction, and the gear seven 15 can drive the connecting rod 12 and the sealing plate four 851 to rotate in the opposite direction until the sealing plate rotates to a horizontal state. At this time, each sealing plug 853 corresponds to each through hole four 852 one by one, and at the same time, the torsion force of the torsion spring 14 can keep the sealing plate four 851 in a horizontal state at all times, so that each sealing plug 853 can be easily reinserted into each through hole four 852.

[0067] The implementation principle of the embodiment of the present application is as follows: the staff first puts the wet plastic particles into the filter barrel 1 2 through the feed pipe 6, and then drives the filter barrel 1 2 and the filter barrel 2 3 to rotate through the first drive component 5. Since the diameter of the filter holes on the filter barrel 2 3 is smaller than the diameter of the filter holes on the filter barrel 1 2, after a period of filtration, there will be plastic particles with larger diameters in the filter barrel 1 2, and plastic particles with smaller diameters in the filter barrel 2 3. The plastic particles in the material barrel 1 and outside the filter barrel 2 3 have the smallest diameter; thereafter, the staff discharges the classified plastic particles into the drying mechanism 8 through the discharge mechanism 7, and then the drying mechanism 8 dries the classified plastic particles. The drying mechanism 8 can use corresponding suitable temperatures for drying plastic particles of different diameters, thereby improving the drying effect of the plastic particles and reducing energy loss and cost.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
