Abstract

This utility model discloses a dehumidifying and drying device for plastic granules, including a frame. Two sets of double-ended threaded rods are rotatably connected to the frame. Each set of double-ended threaded rods is threadedly connected to two sets of connecting members. One or both ends of each set of connecting members are connected to a connecting rod. Each pair of connecting rods is connected to the same set of blocks.

Description

Technical Field

[0001] This utility model relates to the technical field of plastic granule processing, and in particular to a dehumidification and drying device for plastic granules. Background Technology

[0002] Plastic granules refer to small granular substances obtained by decomposing and processing various plastics. They are raw materials used for storing, transporting, and molding plastics in a semi-finished form. They can be divided into thermoplastic plastic granules and thermosetting plastic granules. Thermoplastic plastic granules have linear molecules, are plastic when heated, melt and then solidify upon cooling, and can be repeatedly heated and molded, such as polyethylene, polyvinyl chloride, and polystyrene. Thermosetting plastic granules have a linear molecular structure before initial curing; after initial curing, the linear molecules cross-link, forming a three-dimensional structure. This change is irreversible and cannot be repeatedly heated, such as polyurethane resin, phenolic resin, and melamine resin.

[0003] The existing announcement number is CN221697516U, which discloses a dehumidifying and drying device for plastic granules. Its technical solution includes a first container and a second container, each having a first extension cylinder and a second extension cylinder, with at least a portion of the first extension cylinder inserted into the second extension cylinder. The outer surface of the first extension cylinder has several protrusions and openings. It also includes a support and a linear module. A second support is fixed to a slide of the linear module, and a rotary drive device is mounted on the second support to drive the first container to rotate. This invention forms a sealed container with the first and second containers, and then drives the first container to move via the rotary drive device. Due to the connection between the protrusions and concave portions, the second container rotates synchronously, thereby achieving the turning over of the plastic granules inside the container, thus avoiding the accumulation of plastic granules and uneven drying and dehumidification.

[0004] While the plastic granules can be turned over by flipping the container to ensure even drying and dehumidification, and the material can be removed by separating the two sets of containers after the first container is moved by the linear module, the containers remain horizontal after separation. This requires workers to bend over or reach into the container to work, which involves a large range of motion. Furthermore, granules in the corners or edges of the container often need to be cleaned repeatedly to ensure they are completely removed, making the operation somewhat cumbersome. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dehumidification and drying device for plastic granules.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A dehumidifying and drying device for plastic granules includes a frame. Two sets of double-ended threaded rods are rotatably connected to the frame. Each set of double-ended threaded rods is threadedly connected to two sets of connecting members. One or both ends of each set of connecting members are connected to a connecting rod. Each pair of connecting rods is connected to the same set of blocks. Each pair of blocks is rotatably connected to a rod body. Each pair of rod bodies is rotatably connected to a housing. Each pair of housings is connected to a corresponding block. One end of each pair of housings is connected to a column. Multiple sets of plates are connected to the frame. Each set of plates has grooves formed by straight and curved sections. Multiple sets of columns are slidably connected to corresponding grooves. A pump is installed at one end of the frame. One end of the pump is connected to a first set of pipes, which is connected to a corresponding block and rotatably connected to a rod body. The outer walls of the two sets of rod bodies are respectively connected to a first cylinder and a second cylinder.

[0007] Preferably, the first cylindrical body is rotatably connected to the corresponding shell, the second cylindrical body is rotatably connected to the corresponding shell, one end of the frame is provided with an opening, one end of the second cylindrical body is provided with multiple sets of sliding grooves, one end of the first cylindrical body is connected with multiple sets of sliding blocks, the multiple sets of sliding blocks are respectively slidably connected to and engaged with the corresponding sliding grooves, one end of the frame is equipped with a vacuum pump, one end of the vacuum pump is connected with a pipe assembly, the pipe assembly is connected to the corresponding block, one end of the second cylindrical body is provided with multiple sets of holes, one set of holes is connected to the pipe assembly.

[0008] Preferably, one set of blocks is equipped with a motor one at one end, and the output end of the motor one is connected to the corresponding rod through a coupling. One end of each of the two sets of double-ended threaded rods is connected to a synchronous pulley, and the two sets of synchronous pulleys are connected to each other through synchronous belt transmission. One end of the frame is equipped with a motor two, and the output end of the motor two is connected to the corresponding double-ended threaded rod.

[0009] Preferably, a sliding groove is provided at one end and the other end of the frame, and a slider is connected to one end of each of the multiple sets of connectors, and the multiple sets of sliders are slidably connected to the corresponding sliding groove.

[0010] Preferably, one end of each of the multiple sets of sliders is an inclined surface that fits into the groove.

[0011] Preferably, sealing gaskets are adhered to the joints of the two sets of shells and the joints of cylinder one and cylinder two.

[0012] Preferably, each of the multiple sets of pores is embedded with a filter screen.

[0013] The beneficial effects of this utility model are as follows: 1. Through the cooperation between the set motor 2, double-headed threaded rod and the trough, after the material is dried, the motor 2 is started to drive one set of double-headed threaded rods to rotate, and through the synchronous pulley and synchronous belt, it drives another set of double-headed threaded rods to rotate together. The rotation of the two sets of double-headed threaded rods drives the connecting parts to move, and then through the cooperation of the connecting rod and the block, it drives the two sets of shells to separate. The movement of the two sets of shells drives the column to slide in the trough. When the column slides in the straight section of the trough, the two sets of shells remain horizontal and separate. After the inner cylinder 1 and cylinder 2 of the two sets of shells are completely separated, the column enters the arc section, and then drives the shell to rotate around the connecting rod as the center. The two sets of shells rotate towards the opening. After rotating a certain distance, the shells remain in an inclined state. Under the influence of gravity, the material slides down along the inclined cylinder 1 and cylinder 2 and falls from the opening to complete the collection. It has a wide range of applications to a certain extent. 2. Through the coordination of the pump body two, pipe assembly two, and orifice, the pump body one is started to draw in outside air, which is heated and then transported into the shell through pipe assembly one. Simultaneously, the motor one and pump body two are started. The motor one drives the cylinder two to rotate. With the cooperation of the slide groove two and the slider two, the cylinder two drives the cylinder one to rotate. The cylinder two and cylinder one cause the plastic granules to rotate and come into contact with the hot air, resulting in relatively uniform dehumidification and drying to a certain extent. After the pump body two starts, it extracts the humid air generated by the evaporation of moisture from the plastic granules inside the cylinder two and cylinder one through the orifice, thereby continuously reducing the humidity inside the cylinder to a certain extent and further accelerating the moisture evaporation process. As the cylinder two rotates, the multiple sets of orifices distributed on its surface intermittently connect with pipe assembly two during rotation. This intermittent connection design ensures that humid air can be smoothly discharged through pipe assembly two, while maintaining a relatively stable hot air pressure inside the cylinder during the non-connection phase, reducing heat loss and improving energy utilization efficiency to a certain extent.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1, referring to Figures 1 to 5 A dehumidifying and drying device for plastic granules includes a frame 1. The frame 1 is rotatably connected to two sets of double-ended threaded rods 2. Rotating the double-ended threaded rods 2 causes connecting parts 3 to move. Each set of double-ended threaded rods 2 is threadedly connected to two sets of connecting parts 3. Each set of connecting parts 3 has a connecting rod 4 at one or the other end. The connecting parts 3 drive blocks 5 to move via the connecting rods 4. Every two sets of connecting rods 4 are connected to the same set of blocks 5. Each set of blocks 5 is rotatably connected to a rod 6. Each set of rods 6 is rotatably connected to a housing 8. Each set of housings 8 is connected to a corresponding block 5. Moving the blocks 5 causes the two sets of housings 8 to separate. Each set of housings 8 has a column 9 connected to one or the other end. Multiple sets of plates 10 are connected to the frame 1. Each set of plates 10 has a groove 11, which is composed of straight sections and arc sections. The column 9... The sliding motion in the straight section keeps the shell 8 horizontal. When the column 9 slides in the arc section, it drives the shell 8 to rotate around the connecting rod 4, thus emptying the material. Multiple sets of columns 9 are slidably connected to the corresponding tanks 11. A pump body 12 is installed at one end of the frame 1. The model of the pump body 12 can be selected according to the actual situation. One end of the pump body 12 is connected to the pipe group 13. When the pump body 12 is started, outside air is drawn in, heated, and then transported to the cylinder through the pipe group 13. The pipe group 13 is connected to the corresponding block 5 and is rotatably connected to the rod 6. The outer walls of the two sets of rods 6 are respectively connected to the cylinder 20 and the cylinder 21. The connecting piece 3 is moved by the double-headed threaded rod 2. After moving a certain distance, the column 9 drives the shell 8 to rotate around the connecting rod 4, thus emptying the material. It has a wide range of applications to a certain extent.

[0018] In this embodiment, cylinder 1 20 is rotatably connected to the corresponding shell 8, and cylinder 21 is rotatably connected to the corresponding shell 8. One end of the frame 1 has an opening 17 through which material falls and is collected. One end of cylinder 21 has multiple sets of sliding grooves 22. When cylinder 21 rotates, the sliding grooves 22 and sliders 23 work together to rotate cylinder 1 20, thereby causing the material to tumble. One end of cylinder 20 is connected to multiple sets of sliders 23, which are respectively connected to the corresponding sliding grooves 22. 22 are slidably connected and fit together. One end of the frame 1 is equipped with a second pump body 24. The model of the second pump body 24 can be selected according to the actual situation. One end of the second pump body 24 is connected to a second pipe assembly 25. The second pipe assembly 25 is connected to the corresponding block 5. One end of the cylinder 21 has multiple sets of holes 27. One set of holes 27 is connected to the second pipe assembly 25. The second pump body 24 draws out the humid air generated during the drying of plastic granules through the second pipe assembly 25, so as to avoid excessive moisture in the cylinder and improve the drying efficiency to a certain extent. A set of blocks 5 is equipped with a motor 7 at one end. The model of motor 7 can be selected according to the actual situation. The output end of motor 7 is connected to the corresponding rod 6 through a coupling. Motor 7 drives rod 6 to rotate. Rod 6 drives cylinder 21 to rotate. Cylinder 21 drives cylinder 20 to rotate through the cooperation of slide groove 22 and slider 23. One end of each of the two sets of double-ended threaded rods 2 is connected to a synchronous pulley 14. The two sets of synchronous pulleys 14 are connected to each other through synchronous belt 15. A set of frames 1 is equipped with a motor 16 at one end. The model of motor 16 can be selected according to the actual situation. The output end of motor 16 is connected to the corresponding double-ended threaded rod 2. Motor 16 drives one set of double-ended threaded rods 2 to rotate and drives the other set of double-ended threaded rods 2 to rotate synchronously through the cooperation of synchronous pulley 14 and synchronous belt 15. Both ends of the frame 1 are provided with sliding grooves 18. Multiple sets of connecting parts 3 are each connected to a slider 19 at one end. These sliders 19 are slidably connected to their corresponding sliding grooves 18, providing guidance for the movement of the connecting parts 3. Multiple sets of sliders 23 have inclined surfaces at one end that fit into sliding grooves 22, providing guidance to some extent for the contact process between cylinder 20 and cylinder 21. Sealing gaskets 26 are adhered at the contact points of the two sets of shells 8 and between cylinder 20 and cylinder 21, enhancing the sealing performance to some extent. Filter screens 28 are embedded within multiple sets of orifices 27, preventing plastic particles from being extracted from the orifices 27 to some extent.

[0019] The working principle of this embodiment is as follows: During use, the plastic granules to be dried are placed in a sealed space consisting of cylinder 1 (20) and cylinder 2 (21). Motor 2 (16) drives the double-threaded rods 2 to rotate. Through the transmission of the synchronous pulleys 14 and 15, the two sets of double-threaded rods 2 rotate synchronously, causing the connecting piece 3 to move along the slide groove 18. Through the linkage of the connecting rod 4 and the block 5, the two sets of housings 8 are closed. At this time, the column 9 slides on the straight section of the groove 11, ensuring that cylinder 1 (20) and cylinder 2 (21) fit tightly together. The sealing gasket 26 at the fit ensures the airtightness of the space. Slider 2 (23) engages with slide groove 2 (22), further improving structural stability. Pump 1 (12) is started, and heated outside air is delivered into the cylinder through pipe assembly 1 (13), providing a hot airflow for drying the plastic granules. Simultaneously, motor 7 is started, and its output end drives rod 6 to rotate via coupling. With the sliding engagement of slider 23 and groove 22, rod 6 drives cylinder 20 and cylinder 21 to rotate synchronously, causing the internal plastic particles to continuously tumble and evenly contact the hot airflow, avoiding incomplete drying in certain areas. Pump 24 is started, evacuating air from the cylinder through pipe assembly 25. As cylinder 21 rotates, its multiple sets of perforations 27 intermittently connect with pipe assembly 25 during rotation. The filter screen 28 inside the perforations 27 prevents plastic particles from being sucked into pump 24. During this process, the humid air generated by the evaporation of moisture from the plastic particles is promptly extracted through the perforations 27 and pipe assembly 25, continuously reducing the humidity inside the cylinder and accelerating moisture evaporation. During the non-connected stage, the sealed structure maintains stable hot air pressure inside the cylinder, reducing heat loss. After drying is complete, motor 16 is started again to rotate in the opposite direction, causing the two sets of double-threaded rods 2 to move the connecting parts 3 in the opposite direction, gradually separating the shell 8. The column 9 first slides along the straight section of the trough 11. After the first cylinder 20 and the second cylinder 21 are completely separated, the column 9 enters the arc-shaped section of the trough 11, causing the shell 8 to rotate around the connecting rod 4 towards the opening 17 of the frame 1, ultimately maintaining an inclined state. Under the action of gravity, the plastic granules slide down along the inclined first cylinder 20 and second cylinder 21, and are discharged from the opening 17 to complete the collection. To a certain extent, this method is relatively convenient to operate and has wide applicability.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
