Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and more specifically, to a microwave dryer based on a self-circulating structure of plastic particles. Background Technology

[0002] Plastic granules are raw materials for storing, transporting, and processing plastics in a semi-finished form. Plastics are a type of polymer material. The molecules of these substances can react with each other under certain conditions to form compounds with very large molecular weights. Before processing, plastic granules need to be dried. Only dried plastic granules can be used for processing.

[0003] A search revealed that patent publication number CN220062421U discloses a microwave high-efficiency heating and drying machine for plastic materials. The machine includes a main body with a drying cylinder fixedly connected inside. The outer wall of the drying cylinder is equipped with drying components. A microwave heating device heats the plastic granules inside the drying cylinder, and a fan extracts the hot air for drying. The dried hot air then air-dries the plastic granules. This combination of two drying methods enhances the drying efficiency of the plastic granules, making the drying process more efficient and meeting consumer needs. The desiccant can be replaced by pulling out the storage box, and the presence of a desiccant allows for air drying, enhancing its practicality. During the development of this utility model, the inventors discovered the following problems with the existing technology:

[0004] However, when the device is in use, the placement box is slidably connected to the inner wall of the slide, and there is no limiting structure to limit the placement box. This may result in a large gap between the placement box and the slide, causing the flowing gas to leak out and affecting the drying effect of the desiccant placed in the placement box on the flowing gas.

[0005] Therefore, a microwave dryer based on a self-circulating plastic particle structure is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a microwave dryer based on a plastic particle self-circulation structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a microwave dryer based on a self-circulating structure of plastic particles, comprising a device body, an air supply pipe at the top of the device body, an installation cylinder on the air supply pipe, two movable cylinders slidably connected to the air supply pipe at both ends of the installation cylinder, a plurality of slots equally spaced on the outer side wall of one end of the two movable cylinders, a plurality of locking blocks equally spaced on the outer side wall of both ends of the installation cylinder, which engage with the slots, a locking component between one of the movable cylinders and the installation cylinder, a first filter component fixedly installed at one end of the installation cylinder, a second filter component screwed onto the other end of the installation cylinder, and a desiccant placed between the first filter component and the second filter component.

[0008] Preferably, a rotating rod for adjusting the rotation of the second filter assembly is welded onto the second filter assembly.

[0009] Preferably, the locking assembly includes a locking block, a fixing seat, and a locking bolt. The locking block is welded to the outer wall of the mounting cylinder, and a limit hole is formed on the locking block. The fixing seat is welded to the outer wall of the movable cylinder, and a locking bolt is threaded through the surface of the fixing seat. One end of the locking bolt passes through the limit hole formed on the locking block.

[0010] Preferably, the front surface of the equipment body is hinged to an inspection door, a drying cylinder is installed inside the inspection door, a rotating shaft is rotatably connected inside the drying cylinder, a stirring rod is installed on the outer wall of the rotating shaft, and a material plate is connected to one end of the stirring rod.

[0011] Preferably, the two ends of the air supply pipe are connected to the side wall of the drying cylinder, and the bottom side wall of the drying cylinder is provided with a discharge pipe, one end of which passes through the bottom wall of the equipment body.

[0012] Preferably, an exhaust fan is installed on the air supply pipe and on one side of the mounting cylinder, and the exhaust fan is fixedly installed on the top of the equipment body by bolts.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] Compared with existing technologies, this design achieves a limiting connection for the mounting cylinder by engaging the slot on the movable cylinder with the locking block fixedly connected to the mounting cylinder. Simultaneously, the locking bolt, which is bolted through the fixed base, engages with the limiting hole on the locking block, further locking the mounting cylinder in this limiting connection. This structure effectively limits and fixes the mounting cylinder, preventing it from shaking on the gas delivery pipeline and causing gas leakage. Furthermore, it allows for quick disassembly of the mounting cylinder, facilitating the replacement of the desiccant inside. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] As attached Figures 1 to 4 The microwave dryer shown is based on a self-circulating structure of plastic particles. It includes a device body 1, an air supply pipe 2 at the top of the device body 1, an installation cylinder 3 on the air supply pipe 2, two movable cylinders 4 slidably connected to the air supply pipe 2 and at both ends of the installation cylinder 3, a number of slots 5 are evenly spaced on the outer wall of one end of the two movable cylinders 4, a number of locking blocks 6 are evenly welded to the outer wall of both ends of the installation cylinder 3 and engage with the slots 5, a locking component is provided between one movable cylinder 4 and the installation cylinder 3, a first filter component 10 is fixedly installed at one end of the installation cylinder 3, and a second filter component 11 is screwed to the other end of the installation cylinder 3. The second filter component 11 includes a filter screen and an annular filter frame outside the filter screen. A rotating rod 12 for rotating and adjusting the second filter component 11 is welded to the annular filter frame of the second filter component 11, an internal thread is provided on the inner wall of one end of the installation cylinder 3, and an external thread that engages with the internal thread is provided on the outer side of the annular filter frame of the second filter component 11, and a desiccant 13 is placed between the first filter component 10 and the second filter component 11.

[0022] When installing and using the mounting cylinder 3, the desiccant 13 can be placed inside the mounting cylinder 3 first. Then, the second filter assembly 11 is rotated by the rotating rod 12 to screw the second filter assembly 11 into the mounting cylinder 3. Then, the mounting cylinder 3 is placed on the air supply pipe 2. Next, the two movable cylinders 4 on the air supply pipe 2 are moved. It should be noted that when the mounting cylinder 3 is placed on the air supply pipe 2, the locking blocks 6 at both ends of the mounting cylinder 3 are aligned with the locking slots 5 opened on the movable cylinder 4. Then, the mounting cylinder 3 is rotated so that the locking blocks 6 on the outer sides of both ends of the mounting cylinder 3 rotate to the end of the locking slots 5 opened on the movable cylinder 4. Finally, the mounting cylinder 3 is locked by the locking assembly set between the movable cylinder 4 and the mounting cylinder 3. Example 2

[0023] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0024] In a preferred embodiment, the locking assembly includes a locking block 7, a fixing seat 8, and a locking bolt 9. The locking block 7 is welded to the outer wall of the mounting cylinder 3, and a limit hole is formed on the locking block 7. The fixing seat 8 is welded to the outer wall of the movable cylinder 4, and the locking bolt 9 is threaded through the surface of the fixing seat 8. One end of the locking bolt 9 moves through the limit hole formed on the locking block 7. Furthermore, when locking the mounting cylinder 3 with the limit setting, the locking bolt 9 on the fixing seat 8 can be rotated first, and then one end of the locking bolt 9 is inserted into the limit hole formed on the surface of the locking block 7, thereby preventing the mounting cylinder 3 from rotating later and improving the stability of the connection of the mounting cylinder 3.

[0025] In a preferred embodiment, an inspection door 14 is hinged to the front surface of the equipment body 1. A drying cylinder 15 is installed inside the inspection door 14. A heating assembly is installed inside the inspection door 14 and below the drying cylinder 15 to heat and dry the plastic granules inside the drying cylinder 15. A feeding port for feeding plastic granules into the drying cylinder 15 is provided on the rear side wall of the drying cylinder 15. A rotating shaft 16 is rotatably connected inside the drying cylinder 15. A stirring rod 17 is installed on the outer wall of the rotating shaft 16. One end of the stirring rod 17 is connected to a material plate 18. Both ends of the air supply pipe 2 are connected to the side wall of the drying cylinder 15. The drying cylinder 15 is connected to a discharge pipe 19 on its bottom side wall. One end of the discharge pipe 19 passes through the bottom wall of the equipment body 1. Finally, an exhaust fan 20 is installed on the air supply pipe 2 and located on one side of the mounting cylinder 3. The exhaust fan 20 is fixed to the top of the equipment body 1 by bolts. In use, a heating component is used to heat and dry the plastic particles in the drying cylinder 15. At the same time, a motor installed at one end of the rotating shaft 16 drives the rotating shaft 16. Then, the rotating shaft 16 drives the stirring rod 17 and the material plate 18 to rotate, which agitates the plastic particles in the drying cylinder 15 and improves the drying efficiency of the plastic particles.

[0026] The working process of this utility model is as follows: First, the motor set at one end of the rotating shaft 16 drives the rotating shaft 16. Then, the rotating shaft 16 drives the stirring rod 17 and the material plate 18 to rotate, which turns the plastic particles in the drying cylinder 15 and improves the drying efficiency of the plastic particles. At the same time, the exhaust fan 20 draws out the air containing moisture in the drying cylinder 15 through the air supply pipe 2. After being dried and filtered by the desiccant 13 in the installation cylinder 3, it is discharged back into the drying cylinder 15 through the air supply pipe 2, forming a cycle, which accelerates the removal of moisture in the drying cylinder 15 and improves the drying efficiency.

[0027] When the mounting cylinder 3 needs to be installed and used, the desiccant 13 can be placed inside the mounting cylinder 3 first. Then, the second filter assembly 11 is rotated by rotating rod 12 to screw the second filter assembly 11 into the mounting cylinder 3. Then, the mounting cylinder 3 is placed on the air supply pipe 2. Next, the two movable cylinders 4 on the air supply pipe 2 are moved. It should be noted that when the mounting cylinder 3 is placed on the air supply pipe 2, the locking blocks 6 at both ends of the mounting cylinder 3 are aligned with the locking slots 5 opened on the movable cylinders 4. Then, the mounting cylinder 3 is rotated so that the locking blocks 6 on the outer sides of both ends of the mounting cylinder 3 rotate into the slots 5 opened on the movable cylinders 4. At the end of the slot 5, the locking bolt 9 on the fixed seat 8 is rotated, and then one end of the locking bolt 9 is inserted into the limiting hole opened on the surface of the locking block 7, thereby preventing the installation cylinder 3 from rotating later and improving the stability of the connection of the installation cylinder 3. This structure can limit and fix the installation cylinder 3, prevent the installation cylinder 3 from shaking on the gas supply pipe 2, causing the flowing gas to flow out, and can quickly disassemble the installation cylinder 3, thereby facilitating the replacement of the desiccant 13 inside the installation cylinder 3. The above is the working principle of a microwave dryer based on a self-circulating structure of plastic particles.
