Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, specifically to a modified polymer material mixing and drying device. Background Technology
[0002] Modified polymer materials are based on polymer materials, and their original properties are altered through physical and chemical methods to meet the specific needs of various fields. They are widely used in numerous industries such as electronics, automotive, and aerospace. Their production process often involves a mixing stage, followed by drying to remove moisture and ensure the material's quality and performance stability. The uniformity of drying is crucial for modified polymer material mixtures. Uneven drying, resulting in excessive localized moisture, will negatively impact the molding process, causing defects such as bubbles and cracks in the finished product. Furthermore, it will reduce the material's mechanical properties and aging resistance, severely limiting product quality and lifespan.
[0003] Rotary drum dryers are a common type of traditional drying equipment. However, they have significant drawbacks when processing modified polymer mixtures. These dryers rely primarily on the rotation of the drum to tumble and lift the material within a fixed circumference. In this process, the material only moves in a circular motion within a plane perpendicular to the drum's axis, lacking effective horizontal agitation. This results in incomplete horizontal mixing, leading to significant differences in drying performance across different areas and failing to meet the stringent requirements for uniform drying of modified polymer mixtures. Utility Model Content
[0004] (I) Technical Issues
[0005] The present invention aims to solve the problem of uneven drying when the existing drum dryer processes the modified polymer material mixture, and provides a modified polymer material mixture drying device.
[0006] (II) Technical Content

[0008] Furthermore, the drying drum has several evenly distributed ventilation holes on its side, a material inlet on its side, and a sealing door at the material inlet.
[0009] Furthermore, the drive mechanism includes a motor fixedly mounted on the rear side of the housing, a drive wheel fixedly mounted on the drive shaft of the motor, a driven wheel fixedly mounted on one end of the drying drum, and a belt connecting the drive wheel and the driven wheel.
[0010] Furthermore, the transmission assembly includes a pulley one fixedly mounted at the end of the spiral stirrer, and a pulley two rotatably mounted on the support frame. The pulley one and the pulley two are connected by a belt two. A gear one is fixedly mounted on the outer side of the pulley two. A motor two is fixedly mounted on the support frame.

[0012] Furthermore, the height of the lifting plate is less than the distance from the bottom of the spiral agitator to the inner side of the drying drum.
[0013] (III) Technical Effects
[0014] Compared with existing technologies, the advantages of this invention are as follows: By installing a spiral agitator and lifting plates inside the drying drum, the lifting plates lift the material when the drum rotates, while the spiral agitator simultaneously and powerfully stirs the material horizontally. This ensures the material is fully agitated in both vertical and horizontal directions, preventing uneven mixing in the horizontal direction and guaranteeing uniform heating and dehydration of the material in all parts, thus ensuring stable material properties. The hot air blower and hot air nozzles work together to deliver hot air into the drying drum from multiple angles on the top and rear sides. Combined with the dynamic mixing of the material from all directions, this increases the contact area and frequency between the material and the hot air, accelerating moisture evaporation, shortening drying time, and improving production efficiency.

[0027] Combined with appendix Figure 1 To be continued Figure 8 A modified polymer material mixing and drying device includes a box body 1, with a hinged door on the front. A discharge port 21 is located on the bottom surface of the box body 1, and an exhaust valve 22 is located on the top of the box body 1. Drying rollers 2 are rotatably mounted on the left and right side walls inside the box body 1. The rollers 2 are open at both ends and extend outside the box body 1. Several evenly distributed ventilation holes 8 are provided on the sides of the drying rollers 2. A material inlet 9 is located on the side of the drying rollers 2, and a sealing door 10 is located at the material inlet 9. Hot air nozzles 3 are fixedly mounted on the top and rear sides of the inner wall of the box body 1. A hot air blower 7 is fixedly mounted on the rear side of the box body 1. The air outlet of the fan 7 is connected to the hot air nozzle 3. A drive mechanism for driving the drying drum 2 to rotate is fixed on the outer side of the housing 1. Support frames 4 extending into the inside of the drum 2 and close to the bottom are fixed on both the left and right sides of the housing 1. A spiral stirrer 5 is rotatably connected between the bottoms of the two support frames 4. A transmission component for driving the spiral stirrer 5 to rotate is matched between the end of one of the support frames 4 and the spiral stirrer 5. Multiple lifting plates 6 are fixed on the inner wall of the drying drum 2. The height of the lifting plates 6 is less than the distance from the bottom of the spiral stirrer 5 to the inner side of the drying drum 2.
[0028] In this embodiment, as a preferred technical solution, the driving mechanism includes a motor 11 fixedly disposed on the rear side of the housing 1, a drive wheel 12 fixedly disposed on the drive shaft of the motor 11, a driven wheel 13 fixedly disposed at one end of the drying drum 2, and a belt 14 connecting the drive wheel 12 and the driven wheel 13.
[0029] In this embodiment, as a preferred technical solution, the transmission assembly includes a pulley 15 fixedly disposed at the end of the spiral stirrer 5, and a pulley 16 rotatably disposed on the support frame 4. The pulley 15 and the pulley 16 are connected by a belt 17. A gear 18 is fixedly disposed on the outer side of the pulley 16. A motor 19 is fixedly disposed on the support frame 4. A gear 20 is fixedly disposed on the drive shaft of the motor 19. The gear 18 and the gear 20 mesh with each other.
[0030] The working principle of this modified polymer material mixing and drying device is as follows: A hot air blower 7 generates hot air, which is then delivered through the air outlet to a hot air nozzle 3 fixedly connected to the rear side and top inner wall of the housing 1. The hot air nozzle 3 sprays hot air into the drying drum 2 at multiple angles. The drive mechanism is activated, i.e., the motor 11 rotates, driving the drive wheel 12 on the drive shaft to rotate. This, via the belt 14, causes the driven wheel 13 at one end of the drying drum 2 to rotate accordingly. The drying drum 2 begins to rotate, and the lifting plates 6 on its side lift the material as the drum rotates, causing the material to tumble vertically and increasing the contact area with the hot air. At the same time, the motor 19 on the support frame 4 starts, and the gear 20 on the drive shaft rotates, which drives the gear 18 fixed on the outer side of the pulley 16 that meshes with it to rotate. This causes the pulley 15 connected by the belt 17 to drive the spiral agitator 5 to rotate. The spiral agitator 5 stirs the material in the horizontal direction, so that the material is fully mixed in the horizontal direction. By controlling the forward and reverse rotation of the motor 19, the rotation direction of the spiral agitator 5 is controlled. Under the action of hot air and dual dynamic stirring, the moisture in the material evaporates quickly, and the water vapor is discharged through the vent 8 and finally discharged from the box 1 through the exhaust valve 22 on the top of the box 1.
[0031] The usage process of the modified polymer material mixing and drying device of this utility model is as follows:
[0032] 1. Preparation stage: Check whether all components of the equipment are normal, ensure that the hot air blower 7, motor 11, motor 2 19 and other equipment can operate normally, and open the sealing door 10.
[0033] 2. Feeding: Pour the modified polymer mixture that needs to be dried into the drying drum 2 through the material inlet 9. After filling to the appropriate amount, close the sealing door 10 and the box door.
[0034] 3. Drying Start-up: Turn on the hot air blower 7, adjust it to the appropriate hot air temperature and wind speed, start the motor 11 to make the drying drum 2 start rotating, then start the second motor 19 to drive the spiral agitator 5 to rotate and start the drying operation. During the process, continuously change the forward and reverse rotation of the second motor 19 to control the left and right tumbling of the material.
[0035] 4. Monitoring and Adjustment: During the drying process, by observing the water vapor discharged from the exhaust valve 22 and the equipment operating status, the temperature, wind speed and motor speed of the hot air blower 7 are adjusted in a timely manner to ensure smooth drying.
[0036] 5. Drying complete: When the material reaches the drying requirements, turn off motor 19, motor 11 and hot air blower 7 in sequence, open the box door and sealing door 10, rotate the drying drum 2 so that the material inlet 9 faces downward, the material inlet is also the material outlet, the material falls into the box, open the discharge port 21 to discharge the dried material, and complete the entire drying process.
