Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic drying equipment, in particular to a plastic particle drying equipment with constant temperature control to enhance storage stability. Background Technique
[0002] During the production, storage and subsequent processing of plastic particles, their water content has a crucial impact on product quality. Excessive water content may cause problems such as bubbles, deformation, and performance degradation in plastic products. Therefore, drying is an indispensable link.
[0003] In the traditional plastic particle drying process, at the initial feeding, a large number of plastic particles are prone to agglomerate due to excessive humidity. Then, they maintain an agglomerated state when entering the next link. The moisture inside the agglomerated particles is difficult to effectively evaporate, resulting in an extended drying time and low overall drying efficiency. The uneven drying situation may cause some particles to be incompletely dried, affecting the quality of subsequent plastic processing products. If the excess hot air generated during the drying process cannot be discharged in time, it will form a humid and hot environment in the drying chamber, reducing the water evaporation rate, affecting the drying efficiency, and may also cause the plastic particles to reabsorb moisture, thereby affecting the drying effect and resulting in unstable internal drying temperature. Content of the Utility Model
[0004] The purpose of the utility model is to solve the problem that during the traditional plastic particle drying process, due to excessive humidity during feeding, the particles are prone to agglomerate, resulting in unstable heating temperatures between the particles.

[0012] Further, a funnel is arranged inside the bottom end of the discharge box, and the bottom end of the funnel faces the upper end of the material storage box. The dried plastic particles fall from the bottom end of the drying chamber into the discharge box.

The return baffle 94 is provided at the upper end inside the drying chamber 91. The top end of the discharging box 10 is fixedly connected to the bottom end of the drying component 9.
[0023] As Figure 1 and Figure 4 shown in the figure, the feeding component 2 includes a feeding port 21, a drying fan 22 and a wind shield 23. The bottom end of the feeding port 21 is provided at the top end of the feeding inner box 8. The wind shield 23 is provided at the side wall of the air inlet component 3. The wind shield 23 is provided at the top end of the feeding port 21. The drying fan 22 is provided between the feeding port 21 and the drying fan 22. Plastic particles enter the feeding inner box 8 through the feeding port 21. The wind shield 23 at the top end of the feeding port 21 can play a certain protective role to prevent foreign impurities from entering the feeding channel. The drying fan 22 is provided between the feeding port 21 and the drying fan 22. The drying fan 22 can preliminarily dry or disperse the entering plastic particles to prevent particle agglomeration and enable the particles to enter the next link more evenly.
[0024] As Figure 1 , Figure 2 and Figure 4 shown in the figure, the air inlet component 3 includes an air inlet fan 31, an air inlet pipe 32 and an air inlet 33. The air inlet fan 31 is provided at the top of the feeding component 2. The air inlet pipe 32 is provided outside the feeding component 2.

The air inlet fan 31 provides power for the entry of air and promotes the air to flow along the air inlet pipe 32.
[0025] As Figure 1 , Figure 3 , Figure 4As shown in the figure, the moisture exhaust component 4 includes a wind hood 41, an air outlet duct 42, and a moisture exhaust fan 43. The inner side of the wind hood 41 is covered and connected to the outer side of the left side of the housing 1. The top end of the air outlet duct 42 is fixedly connected to the outer side of the wind hood 41. The moisture exhaust fan 43 is arranged at the bottom end of the air outlet duct 42. The humid air enters the air outlet duct 42 after passing through the wind hood 41.

[0026] As Figures 1 - 3 shown in the figure, the top end of the drying chamber 91 is fixedly connected to the bottom end of the feeding inner box 8, and the bottom end of the drying chamber 91 is fixedly connected to the top end of the discharge box 10. The outer end of the air permeable hole 92 faces the side wall of the housing 1. The air permeable holes 92 on the side wall of the drying chamber 91 ensure that air can be exchanged inside and outside the drying chamber 91. When the air sent by the air inlet component 3 enters the drying chamber 91, the hot air fully contacts the plastic particles, promoting the evaporation of the moisture in the plastic particles. The return baffle 94 arranged at the upper end inside the drying chamber 91 plays a role in changing the air flow direction or preventing the particles from being carried out excessively by the air flow, enabling the particles to have sufficient residence time in the drying chamber 91 for drying. As the moisture in the plastic particles evaporates, the humidity in the drying chamber 91 increases. The inner side of the wind hood 41 is covered and connected to the outer side of the left side of the housing 1, which can effectively collect the humid air discharged from the drying chamber 91.
[0027] As Figure 1 , Figure 2 and Figure 5 shown in the figure, a funnel 11 is arranged inside the bottom end of the discharge box 10. The bottom end of the funnel 11 faces the upper end of the material receiving box 6. The funnel 11 inside the bottom end of the discharge box 10 guides the dried plastic particles to the material receiving box 6, completing the entire drying and discharging process.
[0028] Working principle: As Figures 1 - 5 shown in the figure, the plastic particles enter the feeding inner box 8 through the feeding port 21. The wind shield 23 at the top end of the feeding port 21 can play a certain protective role to prevent foreign impurities from entering the feeding channel.
[0029] A drying fan 22 is arranged between the feeding port 21 and the drying fan 22. The drying fan 22 can preliminarily dry or disperse the entering plastic particles to prevent particle agglomeration and enable the particles to enter the next link more evenly.
[0030] Air enters the air inlet pipe 32 from the air inlet 33. The air inlet fan 31 provides power for the entry of the air, promoting the air to flow along the air inlet pipe 32.
[0031] A filter layer is arranged inside the feeding inner box 8. The entering air is pre-treated for dehumidification and filtration and then conveyed to the drying component 9.
[0032] In the drying chamber 91, the heating element 93 heats the front and rear sides of the drying chamber 91, raising the temperature inside the drying chamber 91. Due to the use of constant temperature control, there are components such as temperature sensors around the drying chamber 91 to monitor the temperature to ensure that the temperature remains at the set constant temperature value, enhancing the storage stability of the plastic particles;
[0033] The ventilation holes 92 on the side wall of the drying chamber 91 ensure that air can be exchanged inside and outside the drying chamber 91; when the air sent by the air inlet assembly 3 enters the drying chamber 91, the hot air comes into full contact with the plastic particles, promoting the evaporation of moisture in the plastic particles;
[0034] The baffle 94 provided at the upper end inside the drying chamber 91 serves to change the air flow direction or prevent the particles from being overly carried out by the air flow, enabling the particles to have sufficient residence time in the drying chamber 91 for drying;
[0035] As the moisture in the plastic particles evaporates, the humidity inside the drying chamber 91 increases. The inner side of the wind hood 41 is connected to the outside of the left side of the housing 1, effectively collecting the moist air discharged from the drying chamber 91;
[0036] The moist air enters the air outlet duct 42 after passing through the wind hood 41, and the dehumidifying fan 43 provides power for the discharge of the moist air, discharging the moist air from the bottom end of the air outlet duct 42 outside the equipment;
[0037] The dried plastic particles fall from the bottom end of the drying chamber 91 into the discharge box 10;
[0038] The funnel 11 on the inner side of the bottom end of the discharge box 10 guides the dried plastic particles to the storage box 6, completing the entire drying and discharging process;
