Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle processing, in particular to a modified plastic particle drying device. Background Technique

[0002] Modified plastic particles are obtained by physically or chemically modifying basic plastic particles. By adding functional additives, changing the molecular structure or introducing special groups, the modified plastic particles can significantly improve key performance indicators such as heat resistance, cold resistance, mechanical strength, and abrasion resistance. At the same time, the modified plastic particles also have good processing performance and environmental protection performance, and can meet the diverse and environmentally sustainable requirements of modern industry for material properties. During the production of modified plastic particles, they need to be cleaned and then dried.

[0003] For example, Chinese Patent Publication No. CN217210142U discloses a plastic particle drying device for the production of modified foamed plastics, including a barrel body. A fixed ring is fixedly connected to the outside of the barrel body. Four uniformly distributed support columns are slidably connected in the fixed ring. The top of the support column is fixedly connected with a movable ring. The barrel body is slidably connected in the movable ring. The bottom of the support column is fixedly connected with a support leg. A spring is sleeved on the outside of the support column. A discharge pipe is fixedly connected to the bottom of the barrel body. In the utility model, a ring pipe is designed in the barrel body. The ring pipe is connected to a gas source through an air inlet pipe and then discharged through the air holes on two shunt pipes, thereby drying the materials in the mesh barrel. Then, the motor drives the rotation of the rotating shaft, and the rotating shaft drives the connecting rod and the stirring plate on the connecting rod to rotate, so that the materials in the mesh barrel are stirred, and the materials are evenly dried, improving the drying rate of the materials.

[0004] However, when the device stirs and dries the plastic particle materials through the stirring plate, the dispersibility of the plastic particle materials is insufficient, resulting in uneven contact between the plastic particles and the hot air, and uneven heating of the plastic particles, which affects the drying efficiency and drying quality. At the same time, when taking materials, the discharge pipe is prone to blockage, making it inconvenient to take materials and the material taking effect is poor.

[0028] The present utility model will be further described below in conjunction with embodiments

[0029] Please refer to Figure 1-7, the utility model provides a modified plastic particle drying device, which includes a drying box 4. One end of the drying box 4 is set as an opening. A cover plate 5 is hinged on the opening end of the drying box 4. A connecting pipe 15 communicating with the inside of the drying box 4 is fixed on the side surface of the cover plate 5. An air conveying hose 16 is rotatably connected in the connecting pipe 15 through a bearing. An exhaust port is opened on the side wall of the drying box 4, and a net plate is installed in the exhaust port. One end of the drying box 4 far away from the opening end is fixed with a joint rod 7 arranged coaxially with the connecting pipe 15. One end of the joint rod 7 far away from the drying box 4 is connected with a connecting rod 8. A connecting component 3 is arranged between the joint rod 7 and the connecting rod 8. A support plate 9 is arranged on one side of the drying box 4. One end of the connecting rod 8 far away from the joint rod 7 is rotatably connected with the support plate 9 and fixed with a large gear 10. A motor 11 is fixed on the side surface of the support plate 9. A small gear 14 meshing with the large gear 10 is fixed on the output end of the motor 11. A material scattering component 1 is arranged inside the drying box 4, and a cleaning component 2 is arranged at one end of the drying box 4; when in use, the plastic particle raw materials to be dried are put into the inside of the drying box 4 through the opening end of the drying box 4, and then the opening end of the drying box 4 is covered by closing the cover plate 5. The air conveying hose 16 is externally connected to a hot air blower. The hot air blower and the motor 11 are started to work. The hot air blower conveys the hot air into the inside of the drying box 4 through the air conveying hose 16 and the connecting pipe 15 to dry the plastic particle raw materials. The air containing water vapor is discharged through the exhaust port. The plastic particle raw materials are blocked by the net plate to prevent the plastic particle raw materials from falling out of the inside of the drying box 4. At the same time, the output end of the motor 11 drives the small gear 14 to rotate, so as to drive the connecting rod 8 to rotate through the cooperation of the small gear 14 and the large gear 10. The connecting rod 8 drives the joint rod 7 and the drying box 4 to rotate, so that the plastic particle raw materials inside the drying box 4 continuously roll. At the same time, through the arranged material scattering component 1, the plastic particle raw materials are evenly separated and the plastic particle raw materials are evenly diffused and rolled, effectively improving the even distribution of the plastic particle raw materials inside the drying box 4, making the raw materials evenly heated, and increasing the drying efficiency of the raw materials; when the plastic particle raw materials are dried, the cover plate 5 is opened, the opening end of the drying box 4 is opened, and the fixed connection between the joint rod 7 and the connecting rod 8 is released through the connecting component 3, so that the drying box 4 can be tilted downward, the opening end of the drying box 4 faces downward, and the raw materials inside the drying box 4 are automatically unloaded through the opening end of the drying box 4 to complete the material taking. The material taking is convenient and the material taking efficiency is effectively improved; when the material scattering component 1 needs to be cleaned after drying, the air conveying pipe of the air pump is connected to the cleaning component 2, the air pump sucks the outside air and compresses and conveys it into the inside of the cleaning component 2, and the cleaning component 2 evenly and finely sprays the airflow with a certain air pressure onto the material scattering component 1 to fully clean the material scattering component 1 and avoid the blockage of the material scattering component 1. The cleaning is convenient.

[0030] Further, as Figure 5 and Figure 6As shown, it is worth specifically stating that the bulk material component 1 includes a partition 101 fixed to the inner side wall of the drying oven 4. There are multiple partitions 101, and the multiple partitions 101 are distributed in a mutually perpendicular and staggered manner. The internal space of the drying oven 4 is divided into multiple chambers 102 by the multiple partitions 101. A plurality of equally spaced through holes 103 are formed on the side surface of the partition 101; during specific operation, the output end of the motor 11 drives the small gear 14 to rotate, thereby driving the connecting rod 8 to rotate through the cooperation of the small gear 14 and the large gear 10. The connecting rod 8 drives the joint rod 7 and the drying oven 4 to rotate, causing the plastic granule raw materials inside the drying oven 4 to continuously tumble. When the plastic granule raw materials inside the drying oven 4 are tumbling, the plastic granule raw materials are separated by the multiple partitions 101, and at the same time, the plastic granule raw materials leak into the multiple different chambers 102 through the multiple through holes 103, thereby evenly separating the plastic granule raw materials and making the plastic granule raw materials evenly spread and roll, effectively improving the even distribution of the plastic granule raw materials inside the drying oven 4, making the raw materials evenly heated, and increasing the efficiency of raw material drying.

[0031] Further, as shown in Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, it is worth specifically stating that the cleaning component 2 includes a ventilation cavity 201 formed at one end inside the drying oven 4. A notch 204 is formed on the side wall of the drying oven 4, and an insertion plate 202 located inside the ventilation cavity 201 is inserted into the notch 204. A blowing hole 206 communicating with the ventilation cavity 201 is formed on the inner side wall of the drying oven 4. There are multiple blowing holes 206, and the multiple blowing holes 206 are equally spaced. A joint sleeve 205 communicating with the ventilation cavity 201 is fixed on the outer side wall of the drying oven 4; when drying the plastic granule raw materials, the insertion plate 202 is inserted into the ventilation cavity 201 to close the blowing hole 206. When it is necessary to clean the through hole 103 after drying is completed, the insertion plate 202 is pulled out from the ventilation cavity 201, so that the blowing hole 206 is opened. The joint sleeve 205 is provided with internal threads. By threadedly connecting the air delivery pipe of the air pump into the joint sleeve 205, the air pump sucks in the outside air and compresses and conveys it into the ventilation cavity 201, and the air flow with a certain air pressure is evenly and finely ejected onto the through hole 103 through the multiple equally spaced blowing holes 206 to fully clean the through hole 103 and avoid blockage of the through hole 103, and the cleaning is convenient.

[0032] Further, as shown in Figure 6 and Figure 7 As shown, it is worth specifically stating that a handle 203 is fixed at the middle of one end of the insertion plate 202, and a rubber sleeve is fitted and sleeved on the surface of the handle 203; during specific operation, the handle 203 is provided to facilitate the installation and removal of the insertion plate 202, which is convenient for operation.

[0033] Further, as shown in Figure 1 and Figure 3 it is worth specifically stating that the connecting component 3 includes a joint plate 304 fixed to one end of the joint rod 7 away from the drying box 4. A rotating seat 301 rotatably connected to the joint plate 304 is fixed to one end of the joint rod 7 close to the connecting rod 8. A locking bolt 302 is threadedly connected to the side surface of the rotating seat 301, and a threaded hole adapted to the locking bolt 302 is provided on the side surface of the joint plate 304. After the plastic granule raw material is dried, the cover plate 5 is opened to open the opening end of the drying box 4. By screwing out the locking bolt 302, the fixed connection between the joint rod 7 and the connecting rod 8 is released, so that the joint rod 7 and the connecting rod 8 can rotate relative to each other, thereby enabling the drying box 4 to tilt downward, making the opening end of the drying box 4 face downward, and the raw material inside the drying box 4 is automatically discharged through the opening end of the drying box 4, completing the material taking. The material taking is convenient and the material taking efficiency is effectively improved.

[0034] The working process of this solution is as follows: When in use, the plastic granule raw material to be dried is put into the drying box 4 through the opening end of the drying box 4, and then the cover plate 5 is closed to cover the opening end of the drying box 4. The air supply hose 16 is externally connected to a hot air blower, and the hot air blower and the motor 11 are started to work. The hot air blower conveys the hot air into the drying box 4 through the air supply hose 16 and the connecting pipe 15 to dry the plastic granule raw material. The air containing water vapor is discharged through the exhaust port. The plastic granule raw material is blocked by the mesh plate to prevent the plastic granule raw material from falling out of the drying box 4. At the same time, the output end of the motor 11 drives the small gear 14 to rotate, so as to drive the connecting rod 8 to rotate through the cooperation of the small gear 14 and the large gear 10. The connecting rod 8 drives the joint rod 7 and the drying box 4 to rotate, so that the plastic granule raw material inside the drying box 4 continuously tumbles. When the plastic granule raw material inside the drying box 4 tumbles, the plastic granule raw material is separated by a plurality of partition plates 101, and at the same time, the plastic granule raw material leaks into a plurality of different chambers 102 through a plurality of through ports 103, thereby evenly separating the plastic granule raw material and making the plastic granule raw material evenly spread and roll, effectively improving the evenness of the plastic granule raw material dispersed inside the drying box 4, making the raw material evenly heated. After the plastic granule raw material is dried, the cover plate 5 is opened to open the opening end of the drying box 4. By screwing out the locking bolt 302, the fixed connection between the joint rod 7 and the connecting rod 8 is released, so that the joint rod 7 and the connecting rod 8 can rotate relative to each other, thereby enabling the drying box 4 to tilt downward, making the opening end of the drying box 4 face downward, and the raw material inside the drying box 4 is automatically discharged through the opening end of the drying box 4, completing the material taking;

[0035] When drying the plastic pellet raw materials, the plug board 202 is inserted into the ventilation cavity 201, and the blowing holes 206 are closed through the plug board 202. When it is necessary to clean the through port 103 after drying is completed, the plug board 202 is pulled out from the ventilation cavity 201, so that the blowing holes 206 are opened. The joint sleeve 205 is provided with internal threads. By screwing the air delivery pipe of the air pump into the joint sleeve 205, the air pump sucks the external air and compresses and conveys it into the ventilation cavity 201, and the air flow with a certain air pressure is evenly and finely ejected onto the through port 103 through a plurality of equally spaced blowing holes 206 to fully clean the through port 103.

[0036] Further, as Figure 1 and Figure 2 shown, it is worth specifically stating that the bottom end of the support plate 9 is fixed with a bottom plate 12, and screw holes 13 are opened on the top side of the bottom plate 12. There are a plurality of screw holes 13 and the plurality of screw holes 13 are symmetrically distributed; during specific work, the bottom plate 12 is fixedly installed by installing bolts in the screw holes 13.

[0038] In summary: the output end of the motor 11 drives the small gear 14 to rotate, thereby driving the connecting rod 8 to rotate through the cooperation of the small gear 14 and the large gear 10. The connecting rod 8 drives the joint rod 7 and the drying box 4 to rotate, so that the plastic pellet raw materials inside the drying box 4 continuously tumble. At the same time, through the provided material scattering component 1, the plastic pellet raw materials are evenly separated and evenly diffused and rolled, effectively improving the uniformity of the plastic pellet raw materials scattered inside the drying box 4, making the raw materials evenly heated, and increasing the efficiency of raw material drying; when the plastic pellet raw materials are dried, the cover plate 5 is opened, the opening end of the drying box 4 is opened, and the fixed connection between the joint rod 7 and the connecting rod 8 is released through the connecting component 3, so that the drying box 4 can be tilted downward, making the opening end of the drying box 4 face downward, and the raw materials inside the drying box 4 are automatically discharged through the opening end of the drying box 4 to complete the material taking. The material taking is convenient and the material taking efficiency is effectively improved; when it is necessary to clean the material scattering component 1 after drying is completed, the air delivery pipe of the air pump is connected to the cleaning component 2, the air pump sucks the external air and compresses and conveys it into the cleaning component 2, and the cleaning component 2 evenly and finely ejects the air flow with a certain air pressure onto the material scattering component 1 to fully clean the material scattering component 1, avoiding the blockage of the material scattering component 1, and the cleaning is convenient.
