A corrosion-resistant modified plastic granule drying mechanism

Abstract

This utility model relates to the field of modified plastics processing technology, and in particular to a drying mechanism for corrosion-resistant modified plastic granules. The mechanism includes a mounting frame on which a first drying cylinder and a second drying cylinder are mounted. The inlet end of the first drying cylinder is connected to a feed pipe, and the outlet end of the first drying cylinder is connected to the second drying cylinder via a guide pipe. The outlet end of the second drying cylinder is equipped with a discharge hopper. By splitting the traditional single long drying cylinder into a first and second drying cylinder arranged vertically, and connecting and transferring materials through the guide pipe, the vertical space is used instead of the horizontal space while maintaining the total drying path length, significantly reducing the equipment's footprint. This solves the problems of large space occupation and limited installation of long drying cylinders. The two-stage drying design extends the residence time of materials within the equipment, allowing for more thorough drying of the corrosion-resistant modified plastic granules.

Description

Technical Field

[0001] This utility model relates to the field of plastic granule processing technology, and in particular to a drying mechanism for corrosion-resistant modified plastic granules. Background Technology

[0002] Modified plastics refer to plastic products made from general-purpose and engineering plastics through processes such as filling, blending, and reinforcement, which improve their properties such as flame retardancy, strength, impact resistance, and toughness. Modified plastic products are typically made by melting plastic granules and then shaping them into the desired form using molds. Modified plastic granules must be kept dry before melting; raw materials with excessive moisture content require drying treatment.

[0003] A plastic granule drying device, disclosed in CN216782347U, includes a support platform and a drying cylinder. A hollow drying cylinder is fixedly installed on the worktable of the support platform. The drying cylinder is horizontally inclined and fixed, with one end closed and the other open along its axial direction. An agitator is also installed inside the drying cylinder, extending along its axial direction, and is driven to rotate by a drive device. However, existing drying devices generally use longer drying cylinders to increase the drying time for plastic granules in order to improve the drying effect. However, longer drying cylinders result in a larger space occupation, affecting installation efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the long drying cylinder in the prior art leads to a large space occupation and affects the installation effect. It provides a corrosion-resistant modified plastic granule drying mechanism that uses a first drying cylinder and a second drying cylinder arranged vertically and a material guide pipe to connect and transfer materials. While ensuring the total drying path length, it uses vertical space to replace horizontal space, which greatly reduces the footprint of the equipment.

[0005] To achieve the above objectives, this utility model provides a corrosion-resistant modified plastic granule drying mechanism, including a mounting frame on which a first drying cylinder and a second drying cylinder are mounted. The feed end of the first drying cylinder is connected to a feed pipe, and the discharge end of the first drying cylinder is connected to the second drying cylinder through a guide pipe. The discharge end of the second drying cylinder is provided with a discharge hopper, and both the first and second drying cylinders are provided with a pushing and turning component.

[0006] As a further description of the above technical solution: the first drying cylinder includes an outer cylinder and an inner cylinder, and a heating wire is provided between the outer cylinder and the inner cylinder.

[0007] As a further description of the above technical solution: the pushing and turning component includes a pushing motor, the pushing motor is connected to the mounting frame, the driving end of the pushing motor is connected to the pushing shaft, and the pushing shaft is provided with multiple pushing blades.

[0008] As a further description of the above technical solution: the second drying cylinder is connected below the first drying cylinder, and the second drying cylinder has the same structure as the first drying cylinder.

[0009] As a further description of the above technical solution: the upper end of the feed pipe is connected to a feed hopper, a rotating shaft is installed inside the feed pipe, a feed rod is connected to the rotating shaft, and one end of the feed rod is connected to a feed motor.

[0010] As a further description of the above technical solution: both the first drying cylinder and the second drying cylinder are connected to an exhaust pipe, the exhaust pipe is connected to a guide pipe, and the outlet end of the guide pipe is connected to the purification box.

[0011] As a further description of the above technical solution: an activated carbon plate is connected inside the purification box, the activated carbon plate is connected to the frame, and the frame is detachably connected to the purification box.

[0012] As a further description of the above technical solution: both the first drying cylinder and the second drying cylinder are provided with reinforcing rods between themselves and the mounting frame.

[0013] The above technical solution has the following advantages or beneficial effects:

[0014] This invention splits the traditional single long drying cylinder into a first drying cylinder and a second drying cylinder arranged vertically. The material is transferred through a guide pipe. While ensuring the total drying path length, the vertical space is used instead of the horizontal space, which greatly reduces the equipment's footprint and solves the problems of large space occupation and limited installation of long drying cylinders. The two-stage drying design extends the residence time of the material in the equipment, which can be used to dry the corrosion-resistant modified plastic particles more thoroughly.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figure 1-4 As shown, the present invention discloses a corrosion-resistant modified plastic granule drying mechanism, including a mounting frame 1, on which a first drying cylinder 2 and a second drying cylinder 3 are mounted. The feeding end of the first drying cylinder 2 is connected to a feeding pipe 4, and the discharging end of the first drying cylinder 2 is connected to the second drying cylinder 3 through a guide pipe 5. The discharging end of the second drying cylinder 3 is provided with a discharge hopper 6. Both the first drying cylinder 2 and the second drying cylinder 3 are provided with a pushing and turning component 7.

[0025] In the technical solution of this utility model, the plastic granules added through the feed pipe 4 can be dried by the first drying cylinder 2 and the second drying cylinder 3. The plastic granules can be pushed to flow in the first drying cylinder 2 and the second drying cylinder 3 by the pushing and turning component 7. By splitting the traditional single long drying cylinder into the first drying cylinder 2 and the second drying cylinder 3 arranged vertically, and realizing the connection and transfer of materials through the guide pipe 5, the longitudinal space is used to replace the transverse space while ensuring the total drying path length, which greatly reduces the footprint of the equipment and solves the problem of large space occupation and installation restrictions of long drying cylinders. The two-stage drying design extends the residence time of materials in the equipment and can be more thoroughly dried for the characteristics of corrosion-resistant modified plastic granules.

[0026] like Figure 1 and Figure 2 As shown, the first drying cylinder 2 includes an outer cylinder 201 and an inner cylinder 202, and a heating wire 203 is provided between the outer cylinder 201 and the inner cylinder 202; by working the heating wire 203 provided between the outer cylinder 201 and the inner cylinder 202, the material flowing inside the inner cylinder 202 can be continuously and stably heated.

[0027] The second drying cylinder 3 is connected below the first drying cylinder 2, and the second drying cylinder 3 has the same structure as the first drying cylinder 2.

[0028] like Figure 1 and Figure 2 As shown, the pusher and turning assembly 7 includes a pusher motor 71, which is connected to the mounting frame 1. The drive end of the pusher motor 71 is connected to the pusher shaft 72, and multiple pusher blades 73 are provided on the pusher shaft 72. By driving the pusher shaft 72 and the pusher blades 73 to rotate through the pusher motor 71, the material is pushed forward and turned over, so that the material can fully contact the heat, avoid uneven drying in some areas, and improve the uniformity and efficiency of drying.

[0029] like Figure 1 and Figure 3 As shown, a feed hopper 8 is connected to the upper end of the feed pipe 4, and a rotating shaft 9 is installed inside the feed pipe 4. A feed rod 10 is connected to the rotating shaft 9, and one end of the feed rod 10 is connected to the feed motor 11. When the feed motor 11 works, it can drive the feed rod 10 to rotate, which can play a role in stirring and pushing the material entering the feed pipe 4, effectively preventing plastic particles from accumulating and clogging during the feeding process, and ensuring stable feeding.

[0030] like Figure 1 As shown, both the first drying cylinder 2 and the second drying cylinder 3 are connected to an exhaust pipe 12, which is connected to a guide pipe 13. The outlet end of the guide pipe 13 is connected to the purification box 14. The exhaust pipe 12 and the guide pipe 13 facilitate the introduction of the waste gas generated in the first drying cylinder 2 and the second drying cylinder 3 into the purification box 14.

[0031] like Figure 1 and Figure 4 As shown, an activated carbon plate 15 is connected inside the purification box 14. The activated carbon plate 15 is connected inside the frame 16, and the frame 16 is detachably connected to the purification box 14. The activated carbon plate 15 can purify the exhaust gas generated during the drying process, adsorbing odors and harmful substances in the exhaust gas. The purified gas is then discharged, reducing environmental pollution. The activated carbon plate 15 is installed inside the detachable frame 16, which is convenient for regular replacement or cleaning, ensuring the continuity of the purification effect.

[0032] like Figure 1 As shown, a reinforcing rod 17 is provided between the first drying cylinder 2 and the second drying cylinder 3 and the mounting frame 1; the reinforcing rod 17 enhances the stability of the installation of the first drying cylinder 2 and the second drying cylinder 3.

[0033] Working principle: The first drying cylinder 2 and the second drying cylinder 3 can dry the plastic granules added through the feed pipe 4. The pushing and turning component 7 can push the plastic granules to flow in the first drying cylinder 2 and the second drying cylinder 3. By splitting the traditional single long drying cylinder into the first drying cylinder 2 and the second drying cylinder 3 arranged vertically, and connecting and transferring materials through the guide pipe 5, the longitudinal space is used to replace the transverse space while ensuring the total drying path length. This greatly reduces the footprint of the equipment and solves the problem of long drying cylinders occupying a lot of space and having limited installation. The two-stage drying design extends the residence time of the material in the equipment and can be used to dry the corrosion-resistant modified plastic granules more thoroughly.
