Description

Technical Field

[0001] This utility model belongs to the technical field of mixing and stirring devices, specifically a mixing and stirring device for halogen-free flame-retardant cable materials. Background Technology

[0002] Mixing and stirring devices are key equipment in industrial production used to achieve uniform mixing, dispersion, or reaction of materials. Through the rotation or reciprocating motion of the stirring components, the original physical state of the materials is broken, and materials of different components, particles, or phases are fully contacted, penetrated, and fused, thereby eliminating the concentration difference, temperature difference, or composition difference between materials and forming a homogeneous mixture.

[0003] During operation, the blades rotate in the same direction, and the material easily forms a unidirectional circulation with the blades. The small difference in relative motion speed between adjacent blades leads to weakened shearing force, making it difficult to effectively break up material agglomerates or separate sticky particles. At the same time, the unidirectional stirring force is difficult to form a complex flow field, and the material tends to accumulate locally, failing to fully participate in mixing, thus reducing the overall stirring and shearing efficiency. In addition, the stirring and shearing system and the heating system lack linkage control, and cannot be turned on or off synchronously according to the material state, resulting in a fragmented operation process. This not only prolongs the production cycle but may also affect the material mixing quality due to improper parameter matching, making it difficult to meet the needs of efficient continuous production and reducing the integration of the device. Therefore, this application proposes a mixing and stirring device for halogen-free flame-retardant cable materials. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a mixing and stirring device for halogen-free flame-retardant cable materials, which effectively solves the problems of low mixing and shearing efficiency and low integration of the mixing and stirring device.

[0008] Preferably, the bottom of the motor is fixedly installed with multiple fixed columns that are fixedly connected to the fixed cylinder, and the rotating tube and the transmission rod are each fitted with a fan that is fixedly connected to the rotating tube and the transmission rod.

[0009] Preferably, the upper end of the fixed cylinder is fixedly installed with a through-hole that penetrates the fixed cylinder, and a connecting cylinder that is fixedly installed on the fixed cylinder opposite to the through-hole.

[0010] Preferably, a filter plate is fixedly installed on the connecting cylinder, a heater is fixedly installed inside the connecting cylinder opposite to the filter plate, and an air outlet is fixedly installed at the bottom of the fixed cylinder, penetrating the fixed cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a stirring mechanism, and utilizing the cooperation between the motor, rotating parts, blades, and scrapers, the output end of the motor drives the rotating rod to rotate.

A transmission rod 8, which is rotatably connected to the fixed cylinder 1, is rotatably connected inside the rotating tube 18. The transmission rod 8 passes through the stirring cylinder 17 and is rotatably connected to it. Rotating components capable of driving the rotating rod 6, transmission rod 8, and rotating tube 18 to rotate synchronously are installed on the rotating rod 6, transmission rod 8, and rotating tube 18. The rotating components include a bevel gear 7 fixedly connected to the rotating rod 6. The rotating rod 6 passes through the bevel gear 7. A driven gear 9 fixedly connected to the transmission rod 8 and rotating tube 18 is sleeved on the transmission rod 8 and rotating tube 18. The driven gear 9 meshes with the bevel gear 7.

[0022] Multiple blades 13 are fixedly installed on the transmission rod 8 and the rotating tube 18, and multiple scrapers 14 are fixedly installed on the transmission rod 8 and the rotating tube 18, which slide against the inner wall of the mixing drum 17. Multiple fixed columns 5 are fixedly installed at the bottom of the motor 4 and are fixedly connected to the fixed cylinder 1. The fixed columns 5 can ensure the stability of the motor 4.

A heater 20 is fixedly installed inside the connecting cylinder 12 and is opposite to the filter plate 11. An air outlet 16 is fixedly installed at the bottom of the fixed cylinder 1.

[0023] During operation, halogen-free flame-retardant cable material (hereinafter referred to as material) is poured into the feed inlet 10. The material enters the mixing drum 17 through the feed inlet 10. The motor 4 and heater 20 are turned on. The output end of the motor 4 drives the rotating rod 6 to rotate. The rotating rod 6 drives the bevel gear 7 to rotate. The bevel gear 7 drives the two driven gears 9 connected to it to rotate in different directions. The two driven gears 9 drive the rotating tube 18 and the transmission rod 8 to rotate in different directions. The rotating tube 18 and the transmission rod 8 drive the blades 13 on the rotating tube 18 and the transmission rod 8 to rotate in different directions. The blades 13 rotating in different directions will cut and mix the material. Compared with the blades 13 rotating in the same direction, the blades 13 rotating in different directions will generate greater shearing force, thereby improving the efficiency of material cutting and mixing.

Then the air will flow out from the air outlet 16 at the bottom of the fixed cylinder 1. The shearing and heating operations can be started or stopped at the same time, which improves the integration of the device.

[0025] Working principle: During operation, halogen-free flame-retardant cable material (hereinafter referred to as material) is poured into the feed inlet 10. The material will enter the mixing drum 17 through the feed inlet 10. When the motor 4 and heater 20 are turned on, the output end of the motor 4 will drive the rotating rod 6 to rotate. The rotating rod 6 will drive the bevel gear 7 to rotate. The bevel gear 7 will drive the two driven gears 9 connected to it to rotate in different directions. The two driven gears 9 will drive the rotating tube 18 and the transmission rod 8 to rotate in different directions. The rotating tube 18 and the transmission rod 8 will drive the blades 13 on the rotating tube 18 and the transmission rod 8 to rotate in different directions. The blades 13 rotating in different directions will shear the material. Compared with the blades 13 rotating in the same direction, the blades 13 rotating in different directions will generate greater shearing force, thereby improving the material shearing efficiency. In addition, the rotating tube 18 and the transmission rod 8 will drive the scraper 14 on the rotating tube 18 and the transmission rod 8 to rotate. The rotation of the scraper 14 will scrape off the material adhering to the inner wall of the mixing drum 17, avoiding the material remaining in the mixing drum 17 and affecting the shearing work.

[0026] Simultaneously, the rotating tube 18 and the transmission rod 8 can drive the fan 19, which is fixedly connected to the rotating tube 18 and the transmission rod 8, to rotate in opposite directions.

The air will flow into the fixed cylinder 1 from the filter plate 11 near the heater 20. After heat exchange is completed at the heater 20 (the heater 20 can be an electric heating rod), it heats the stirring cylinder 17, thereby heating the material inside the stirring cylinder 17. Then the air will flow out from the air outlet 16 at the bottom of the fixed cylinder 1. The shearing, mixing and heating operations can be started or stopped at the same time, which improves the integration of the device.
