[0002] ASA plastic granules are graft copolymers of acrylate rubber and acrylonitrile and styrene. They are often used to manufacture plastic shells. Drying is a key process in their production.

[0003] Existing drying equipment uses agitation to accelerate the drying of materials, but some materials still have poor flowability during drying, resulting in low efficiency and particularly poor uniformity in drying. Utility Model Content

The output end of the electric push rod is connected to a lifting plate, and the top of the lifting plate is connected to a drying plate. The drying plate is connected to the inner wall of the drying cylinder.

[0007] The top of the drying tray is connected to a connecting cylinder, the bottom of the connecting cylinder has a flow hole, and the top of the connecting cylinder is connected to a scattering tray.

[0008] Preferably, a motor is connected to the bottom of the discharge cylinder, and a rotating shaft is driven to the output end of the motor.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Please see Figures 1 to 7 A uniformly dried ASA plastic granules drying device includes a drying cylinder 1 and a support frame 2 connected to the outside of the drying cylinder 1. A discharge cylinder 4 is connected to the bottom of the drying cylinder 1. The lower part of the drying cylinder 1 is conical, so when the material reaches the lower part of the drying cylinder 1, it will be affected by the conical surface and fall to the discharge cylinder 4, and then be discharged through the spiral blades 10. Through holes are opened on both sides of the drying cylinder 1 and the support frame 2. A fixed frame 6 is connected in the through holes. The interior of the fixed frame 6 is open, and a groove is opened on one side of the fixed frame 6. An electric push rod 701 is set in the groove, and the connecting line of the electric push rod 701 is arranged through the internal space of the fixed frame 6. It should be noted that the fixed frame 6 passes through the support frame 2 and the drying cylinder 1, so that the connecting line is connected to the external equipment through the fixed frame 6. At the same time, the fixed frame 6 does not affect the sealing of the drying cylinder 1, so that the internal temperature of the drying cylinder 1 can be kept relatively stable when the drying cylinder 1 is working. A dynamic flow component 7 is connected to one side of the fixed frame 6.

[0026] The dynamic flow assembly 7 includes an electric push rod 701, which is externally connected to the inside of the fixed frame 6. The output end of the electric push rod 701 is connected to a lifting plate 702, and the top of the lifting plate 702 is connected to a drying plate 703. The drying plate 703 is connected to the inner wall of the drying cylinder 1.

[0027] The top of the drying tray 703 is connected to a connecting cylinder 704, the bottom of the connecting cylinder 704 is provided with a flow hole 705, and the top of the connecting cylinder 704 is connected to a scattering tray 706.

[0028] When drying materials, the output end of motor 8 drives the rotating shaft 9 to rotate, which causes the rotating shaft 9 to drive the spiral blades 10 to rotate forward, which will transport the materials on the drying tray 703 to the scattering tray 706 through the connecting cylinder 704. The top of the scattering tray 706 is an outward sloping surface, so the materials will slide and scatter on the scattering tray 706 and then onto the drying tray 703 for reciprocating motion.

[0029] It should be further added that the top of the drying tray 703 is a sloping surface that collapses towards the center. Therefore, after the material falls onto the drying tray 703, it will continue to roll towards the center on the drying tray 703, and then roll again to the spiral blade 10, so as to realize the material's repeated rolling and scattering.

[0030] It is important to note that because of the flow hole 705 at the bottom of the connecting cylinder 704, the material is conveyed by the spiral blades 10 only when it rolls towards the center on the drying tray 703.

[0031] Furthermore, during the rolling and scattering process described above, the material will be lifted by the electric push rod 701, thus achieving the throwing of the material. Specifically, the output end of the electric push rod 701 pushes the lifting plate 702 to rise and fall, causing the lifting plate 702 to drive the drying plate 703 to rise and fall, thereby achieving the throwing of the material by lifting the drying plate 703.

[0032] Therefore, when drying materials, the drying device also throws, rolls, and scatters the materials, which greatly improves the fluidity of the materials during drying, thereby improving the drying efficiency and the uniformity of drying.

[0033] It should be noted that when the spiral blade 10 rotates forward, the material is conveyed upward, so the material will not fall into the middle of the drying tray 703.

[0034] A motor 8 is connected to the bottom of the discharge cylinder 4. A rotating shaft 9 is connected to the output end of the motor 8. The rotating shaft 9 is rotatably connected to the inner bottom surface of the drying cylinder 1. A spiral blade 10 is connected to the outside of the rotating shaft 9.

[0035] The spiral blade 10 is located inside the discharge cylinder 4, and the spiral blade 10 is located in the middle of the fixed frame 6, the drying tray 703, and the scattering tray 706.

[0036] The top of the drying cylinder 1 is connected to the feed shell 3. The material to be dried is added to the drying cylinder 1 through the feed shell 3. The discharge cylinder 4 is connected to the discharge pipe 5 on one side.

[0037] When the material needs to be discharged after drying, the output end of the motor 8 reverses to drive the rotating shaft 9 and the spiral blade 10 to reverse. At this time, the spiral blade 10 will convey the material on the drying tray 703 downwards. When the material is conveyed to the bottom of the drying tray 703, the material will fall onto the discharge cylinder 4 on the conical surface.

[0038] At this time, the reverse rotation of the spiral blade 10 will transport the material at the discharge cylinder 4 to the discharge pipe 5 for discharge.

[0039] The support frame 2 has two fixed plates 11 on its external connection. The two fixed plates 11 are symmetrically distributed, and a hot air blower 12 is connected to the top of each of the two fixed plates 11.

[0040] One end of the hot air blower 12 is connected to an air conveying pipe 13, which passes through the drying cylinder 1. One end of the air conveying pipe 13 is connected to an air outlet 14. When the material is drying, the hot air blower 12 is powered on, and the heating wire inside it is powered on and heats up, exchanging heat with the cold air to raise the air temperature. The hot air blown out by the hot air blower 12 is transported to the air outlet 14 through the air conveying pipe 13, and the hot air is blown out into the drying cylinder 1 through the air outlet 14. It should be noted that the air outlet 14 is facing the bottom of the drying tray 703 and blows hot air out towards the drying tray 703 to further improve the drying efficiency of the material.

[0041] The hot air blower 12 is already a very mature technology and is a well-known technology. Those skilled in the art can and should understand its specific functions and structure, so it will not be elaborated on here.

[0042] When using this utility model:

[0043] First, the material to be dried is added to the drying cylinder 1 through the feed shell 3. When the material is drying, the hot air blower 12 is powered on, and the heating wire inside it is powered on and heats up, exchanging heat with the cold air to raise the temperature of the air. The hot air blown out by the hot air blower 12 is transported to the air outlet 14 through the air duct 13, and hot air is blown out of the interior of the drying cylinder 1 through the air outlet 14.

[0044] Secondly, during material drying, the output end of motor 8 drives the rotating shaft 9 to rotate, which in turn drives the spiral blades 10 to rotate forward, conveying the material on the drying tray 703 to the scattering tray 706 through the connecting cylinder 704. The top of the scattering tray 706 is an outward sloping surface, so the material slides and scatters on the scattering tray 706 onto the drying tray 703 for repeated cycles. The top of the drying tray 703 is a sloping surface that collapses towards the center, so after the material falls onto the drying tray 703, it continues to roll towards the center on the drying tray 703, and then rolls again to the spiral blades 10, thus realizing the repeated rolling and scattering of the material.

[0045] Then, during the rolling and scattering process described above, the material will be lifted by the electric push rod 701, thus achieving the throwing of the material. Specifically, the output end of the electric push rod 701 pushes the lifting plate 702 to rise and fall, causing the lifting plate 702 to drive the drying plate 703 to rise and fall, thereby achieving the throwing of the material by lifting the drying plate 703.

[0046] Finally, when the material needs to be discharged after drying, the output end of the motor 8 reverses to drive the rotating shaft 9 and the spiral blades 10 to reverse. At this time, the spiral blades 10 will convey the material on the drying tray 703 downwards. When the material is conveyed to the bottom of the drying tray 703, the material will fall onto the discharge cylinder 4 on the conical surface. At this time, the spiral blades 10 reverse to convey the material at the discharge cylinder 4 to the discharge pipe 5 for discharge.
