Description

Technical Field

[0001] This utility model relates to the field of plastic particle processing technology, and in particular to a dehumidification device for processing modified plastic particles. Background Technology

[0002] Modified plastic particles are high-performance materials produced by adding functional additives to general-purpose or engineering plastic matrices, such as modified polypropylene, modified ABS, modified PC ABS, modified reinforced nylon, flame-retardant PCABS, flame-retardant toughened nylon, and PE bonding resin, through physical or chemical modification. They possess excellent mechanical properties, heat resistance, corrosion resistance, and processing performance, and are widely used in various industrial fields such as automotive, electronics, construction, and packaging. Dehumidification is a crucial step in the production of modified plastic particles. Its purpose is to remove moisture from the raw materials to prevent defects such as bubbles, silver streaks, and reduced strength caused by moisture vaporization during subsequent high-temperature processing, thus affecting product quality and yield. Dehumidification equipment plays a vital role in the production process of modified plastic particles. As a core component of the pretreatment stage, its dehumidification efficiency and uniformity have a decisive impact on the quality stability and processing safety of the final product.

[0003] Utility model patent CN210389769U discloses a dehumidification device for processing plastic particles, including a main body, control panel, feed pipe, discharge pipe, stirring mechanism, dehumidification mechanism, moisture absorption mechanism, and circulation mechanism. This device fully disperses the plastic particles through a stirring and circulation system, and combines this with a low-temperature hot air introduction method for drying and dehumidification, avoiding the impact of high temperatures on the properties of the plastic particles and improving dehumidification efficiency. However, many shortcomings still exist in practical applications.

[0004] Especially during the dehumidification process of modified plastic particles, existing dehumidification equipment struggles to achieve uniform distribution of plastic particles within the drying chamber. This leads to severe particle accumulation and uneven heating in some areas, resulting in incomplete dehumidification or localized overheating. Furthermore, traditional equipment often uses heating components to directly contact the plastic particles for heating and drying. While this increases the drying speed, improper temperature control can easily cause the plastic particles to melt, clump, or even deteriorate, severely impacting material properties and subsequent processing quality. Therefore, to address the numerous shortcomings of existing technologies, there is an urgent need to propose an innovative dehumidification device for processing modified plastic particles. Utility Model Content

[0005] The purpose of this invention is to provide a dehumidification device for processing modified plastic particles, which solves the problem that existing dehumidification devices are unable to achieve uniform distribution of plastic particles in the drying chamber, resulting in severe particle accumulation and uneven heating in some areas, thus causing incomplete dehumidification or local overheating.

[0006] To achieve the above objectives, this utility model provides a dehumidification device for processing modified plastic particles, including a frame, and a support rod rotatably connected to the inner side of the frame, with a support cylinder sleeved on the support rod;

[0007] A drive motor is bolted to one side of the outer wall of the frame, and one end of the support rod passes through the side wall of the frame and is connected to the output shaft of the drive motor. The support cylinders are distributed in a mesh pattern. Both sides of the support cylinders are provided with arc-shaped air hoods that are fixedly connected to the inner wall of the frame. A hot air blower is bolted to one side of the outer wall of the frame, and one side of each of the two arc-shaped air hoods is connected to the outlet of the hot air blower. A heating plate is provided at the bottom of the support cylinder. A side frame is fixedly connected to one side of the frame, and a screw is rotatably connected to the inner side of the side frame. One end of the screw is connected to a nut seat by threaded engagement. One side of the nut seat is fixedly connected to one side of the heating plate. One end of the screw is connected to one end of the support rod by a belt winding.

[0008] Several agitator rods are fixedly connected to the bearing rod, and a cover plate is rotatably connected to one side of the bearing cylinder via a hinge.

[0009] One side of the frame is equipped with a connecting pipe, and both ends of the connecting pipe penetrate the side wall of the frame and are connected to one side of the two arc-shaped air outlets respectively. One end of the connecting pipe is connected to the outlet of the hot air blower through a connecting pipe.

[0010] One side of the nut seat is fixedly connected to a connecting rod, and one end of the connecting rod passes through the side wall of the frame via a movable groove, and one end of the connecting rod is fixedly connected to one side of the heating plate.

[0011] One end of the screw is rotatably connected to the inner wall of the side frame via a rotating shaft, and the other end of the screw passes through the side wall of the side frame via a bearing sleeve. One end of the bearing rod is rotatably connected to the inner wall of the frame via a rotating shaft, and the other end of the bearing rod passes through the side wall of the frame via a bearing sleeve.

[0012] Both the screw and the bearing rod are fitted with pulleys, and the two pulleys are connected by a belt winding around each other.

[0013] This utility model discloses a dehumidification device for processing modified plastic particles. By employing a rotating support cylinder structure, combined with the transmission between the drive motor and the support rod, it achieves dynamic circulation and thorough dispersion of the plastic particles during the drying process. This effectively prevents uneven heating and incomplete dehumidification caused by material accumulation, improving dehumidification efficiency and product quality consistency. Simultaneously, a ring-shaped hot air system formed by the arc-shaped air outlet and the hot air blower ensures that hot air is evenly blown onto the plastic particles around the rotation direction of the support cylinder, enhancing convective heat transfer and increasing the drying rate. The heating plate reciprocates via a linkage mechanism consisting of a nut seat, screw, and belt, allowing the heat generated by the heating plate to dynamically adjust its heating position according to the rotation rhythm of the support cylinder. This avoids melting and clumping problems caused by direct contact with the plastic particles, ensuring heating effectiveness while reducing the risk of material damage. Furthermore, the device is compact, operates stably, and is highly automated, possessing excellent temperature control adaptability and process flexibility. It is particularly suitable for the efficient and safe dehumidification needs of various types of modified plastic particles. Attached Figure Description

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 .

[0023] A dehumidification device for processing modified plastic particles includes a frame 1, and a support rod 3 is rotatably connected to the inner side of the frame 1, and a support cylinder 2 is sleeved on the support rod 3.

[0024] A drive motor 13 is fixedly connected to one side of the outer wall of the frame 1 by bolts, and one end of the support rod 3 passes through the side wall of the frame 1 and is connected to the output shaft of the drive motor 13. The support cylinder 2 is distributed in a mesh pattern. Both sides of the support cylinder 2 are provided with arc-shaped air outlet hoods 5 fixedly connected to the inner wall of the frame 1. A hot air blower 12 is fixedly connected to one side of the outer wall of the frame 1 by bolts, and one side of each of the two arc-shaped air outlet hoods 5 is connected to the outlet of the hot air blower 12. A heating plate 17 is provided at the bottom of the support cylinder 2. A side frame 6 is fixedly connected to one side of the frame 1, and a screw 7 is rotatably connected to the inner side of the side frame 6. One end of the screw 7 is connected to a nut seat 8 by threaded engagement. One side of the nut seat 8 is fixedly connected to one side of the heating plate 17. One end of the screw 7 is connected to one end of the support rod 3 by a belt 14.

[0025] First, the modified plastic particles that need to be dehumidified are put into the support cylinder 2, which has a mesh structure. The support cylinder 2 is rotatably connected to the frame 1 through the support rod 3 and is driven to rotate by the drive motor 13 fixedly connected to one side of the outer wall of the frame 1. After the drive motor 13 is started, the support rod 3 drives the support cylinder 2 to rotate synchronously, so that the plastic particles inside continuously roll and disperse under the action of centrifugal force and gravity, forming a uniform distribution state, avoiding the problem of uneven heating caused by accumulation in traditional equipment. Meanwhile, a hot air blower 12 is provided on one side of the outer wall of the frame 1. Its outlet is connected to two arc-shaped air outlet hoods 5 through a pipe. The arc-shaped air outlet hoods 5 are respectively set on both sides of the bearing cylinder 2 and fixedly connected to the inner wall of the frame 1. During the rotation of the bearing cylinder 2, the hot air generated by the hot air blower 12 is evenly blown onto the surface of the rotating plastic particles through the arc-shaped air outlet hoods 5, realizing efficient and uniform drying and dehumidification. In addition, a heating plate 17 is provided at the bottom of the bearing cylinder 2. The heating plate 17 forms a sliding transmission structure with the screw 7 in the side frame 6 through the nut seat 8. One end of the screw 7 is linked to the bearing rod 3 through the belt 14. When the bearing rod 3 rotates, the screw 7 is driven to rotate synchronously through the belt 14, thereby driving the nut seat 8 to move along the axial direction of the screw 7, and driving the heating plate 17 to move back and forth under the bearing cylinder 2, so that the heat generated by the heating plate 17 can be evenly distributed in the bottom area of ​​the bearing cylinder 2, avoiding the occurrence of local overheating or heating blind spots.

[0026] Furthermore, several stirring rods 18 are fixedly connected to the support rod 3, and a cover plate 4 is rotatably connected to one side of the support cylinder 2 via a hinge. After the plastic particles are loaded into the support cylinder 2, the feed inlet is sealed by the cover plate 4 to prevent material leakage during the drying process. At the same time, as the support rod 3 rotates and drives the support cylinder 2 to rotate, the stirring rods 18 rotate synchronously with the support rod 3, which plays an auxiliary role in stirring and dispersing the internal plastic particles, avoiding particle accumulation or poor flow, improving the uniformity of material heating and dehumidification efficiency, and achieving the effect of enhancing the dynamic circulation capacity of the material and improving the drying effect.

[0027] Furthermore, a connecting pipe 16 is provided on one side of the frame 1, and both ends of the connecting pipe 16 penetrate through the side wall of the frame 1 and are connected to one side of the two arc-shaped air outlet hoods 5 respectively. One end of the connecting pipe 16 is connected to the outlet of the hot air blower 12 through the connecting pipe 11. After the hot air blower 12 is started, the generated hot air enters the connecting pipe 16 through the connecting pipe 11 and is evenly distributed to the arc-shaped air outlet hoods 5 on both sides by the connecting pipe 16, so as to achieve annular air blowing coverage of the area around the bearing cylinder 2, ensuring uniform distribution of hot air, improving heat energy utilization, and achieving the effect of optimizing the hot air circulation path and improving drying uniformity.

[0028] Furthermore, a connecting rod 9 is fixedly connected to one side of the nut seat 8, and one end of the connecting rod 9 passes through the side wall of the frame 1 via the movable groove 10. The connecting rod 9 is also fixedly connected to one side of the heating plate 17. When the nut seat 8 moves axially along the screw 7, it drives the connecting rod 9 to slide in the movable groove 10, thereby pushing the heating plate 17 to move synchronously. This structure not only realizes the reciprocating motion function of the heating plate 17, but also ensures the stability and guiding accuracy of its running trajectory, avoiding the phenomenon of the heating plate 17 shifting or getting stuck during the movement, thus achieving the effect of enhancing the smooth operation and adjustment accuracy of the heating component.

[0029] Furthermore, one end of the screw 7 is rotatably connected to the inner wall of the side frame 6 via a rotating shaft, and the other end of the screw 7 passes through the side wall of the side frame 6 via a bearing sleeve. One end of the bearing rod 3 is rotatably connected to the inner wall of the frame 1 via a rotating shaft, and the other end of the bearing rod 3 passes through the side wall of the frame 1 via a bearing sleeve. This ensures that the screw 7 and the bearing rod 3 each have a stable rotational support structure, effectively reducing vibration and friction loss during operation, extending the service life of the equipment, and ensuring the stable operation of the belt drive system, thereby improving the overall structural stability and transmission efficiency.

[0030] Furthermore, pulleys 15 are fitted onto one end of the screw 7 and one end of the bearing rod 3, and the two pulleys 15 are connected by a belt 14. While the drive motor 13 drives the bearing rod 3 to rotate, the power is transmitted to the screw 7 through the linkage between the pulleys 15 and the belt 14, so that it rotates synchronously. This drives the nut seat 8 to move the heating plate 17 back and forth, realizing the linkage control between the heating component and the bearing cylinder 2, improving the automation and coordination of the equipment, and achieving the effect of optimizing the transmission layout and improving the collaborative work of the system.

[0031] In summary:

[0032] First, the modified plastic particles that need to be dried and dehumidified are loaded into the mesh-distributed bearing cylinder 2 through the cover plate 4, which is rotatably connected by a hinge on one side of the bearing cylinder 2. Then, the cover plate 4 is closed to prevent leakage of materials during the drying process. The drive motor 13, which is fixed to one side of the outer wall of the frame 1, is started. Its output shaft passes through the side wall of the frame 1 through the bearing sleeve and is connected to one end of the bearing rod 3. The bearing rod 3 is rotated, and the bearing cylinder 2 is sleeved on the bearing rod 3. During its rotation, the bearing cylinder 2 is rotated synchronously, so that the plastic particles inside are continuously tumbling and dispersed under the action of centrifugal force and gravity, forming a dynamic circulation state, avoiding the problem of uneven heating or incomplete drying caused by accumulation. Meanwhile, as the support rod 3 rotates, several agitator rods 18 fixed on it also rotate synchronously with the support rod 3, further stirring and dispersing the plastic particles in the support cylinder 2, enhancing the fluidity and uniformity of the material, and improving drying efficiency. A hot air blower 12 is provided on one side of the outer wall of the frame 1, and its outlet is connected to the connecting pipe 16 through the connecting pipe 11. The two ends of the connecting pipe 16 pass through the side wall of the frame 1 and are connected to two arc-shaped air outlet hoods 5 set on both sides of the support cylinder 2. When the hot air blower 12 is running, the hot air generated enters the connecting pipe 16 through the connecting pipe 11 and is evenly distributed to the two arc-shaped air outlet hoods 5, thereby achieving annular air blowing coverage of the area around the rotating support cylinder 2, ensuring that the hot air can be evenly blown onto the surface of all plastic particles, improving heat energy utilization and drying uniformity. In addition, a heating plate 17 is provided at the bottom of the bearing cylinder 2. The heating plate 17 is fixedly connected to the nut seat 8 via a connecting rod 9. The nut seat 8 is engaged with a screw 7 rotatably connected inside the side frame 6 via a threaded connection. One end of the screw 7 is rotatably connected to the inner wall of the side frame 6 via a rotating shaft, and the other end extends through the side wall of the side frame 6 via a bearing sleeve, with a pulley 15 sleeved at that end. At the same time, one end of the bearing rod 3 is also rotatably connected to the inner wall of the frame 1 via a rotating shaft, and the other end extends through the side wall of the frame 1 via a bearing sleeve, with a pulley 15 sleeved at the same end. The two pulleys... The components 15 are connected by a belt 14 to form a linkage transmission structure. When the drive motor 13 drives the bearing rod 3 to rotate, the screw 7 rotates synchronously through the transmission action of the pulley 15 and the belt 14. This drives the nut seat 8 to move along the axial direction of the screw 7, causing the connecting rod 9 and the heating plate 17 to slide in the movable groove 10. This enables the heating plate 17 to reciprocate below the bottom of the bearing cylinder 2, so that the heat generated can be evenly distributed in the bottom area of ​​the bearing cylinder 2, avoiding local overheating or the occurrence of heating blind spots, and further improving the drying effect and temperature control accuracy.By setting up a cooperative structure of rotating bearing cylinder 2, bearing rod 3, and stirring rod 18, the plastic particles are fully dispersed and dynamically circulated during the drying process, effectively avoiding uneven heating caused by material accumulation in traditional equipment, and improving dehumidification efficiency and product quality consistency. The arc-shaped air outlet hood 5, combined with the connecting pipe 16 and the hot air blower 12 to form a ring-shaped hot air system, allows hot air to be evenly blown around the surface of the plastic particles around the bearing cylinder 2, enhancing the convective heat transfer effect and improving the drying rate and heat energy utilization rate. The heating plate 17 is connected by a linkage mechanism consisting of nut seat 8, connecting rod 9, and screw 7. The device achieves reciprocating movement, resulting in more uniform heat distribution and avoiding melting and agglomeration problems caused by direct contact, thus reducing the risk of material damage. The linkage design between pulley 15 and belt 14 not only optimizes the transmission layout but also improves the system's coordination and automation. The overall device is compact, runs smoothly, and is easy to operate, with good temperature control adaptability and process flexibility. It is particularly suitable for the efficient and safe dehumidification needs of different types of modified plastic particles, providing a stable and reliable technical guarantee for the large-scale production of modern high-performance modified plastics, and has broad application prospects and promotional value.
