Description

Technical Field

[0001] This utility model relates to the field of polypropylene production and processing equipment, specifically a modified polypropylene heating and mixing device. Background Technology

[0002] Polypropylene is a thermoplastic resin obtained by polymerizing propylene. It is a white, waxy material that is transparent and lightweight, with a melting point as high as 167°C.

[0003] In the production and processing of modified polypropylene, it is typically mixed in a molten state with other ingredients, requiring heated mixing equipment. However, current modified polypropylene heating and mixing equipment mostly employs a single heating module and stirring structure, limiting the stirring and flow patterns, hindering rapid heat diffusion, resulting in low heating and homogenization efficiency and poor uniformity. Therefore, this paper proposes a modified polypropylene heating and mixing device to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a modified polypropylene heating and mixing device to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a modified polypropylene heating and mixing device, comprising a heat-radiating steel pipe, a material-homogenizing spiral blade, and an electromagnetic heating induction coil. Four heat-radiating steel pipes arranged in a ring are each equipped with a material-homogenizing spiral blade, and two symmetrically positioned material-homogenizing spiral blades have the same spiral direction. Each heat-radiating steel pipe contains an electromagnetic heating induction coil, and gear one and gear two located on the heat-radiating steel pipe are meshed and connected for transmission. Gear two is mounted on the shaft end of a motor. The top end of the heat-radiating steel pipe is rotatably connected to the opening of a ceramic cap via a bearing.

[0006] Preferably, the heat-radiating steel pipe is rotatably installed at the corresponding part of the ring frame.

[0007] Preferably, four protruding plates are provided at the annular hole on the inner side of the ring frame, and each protruding plate is fixedly connected to the corresponding motor.

[0008] Preferably, the ceramic cover has ventilation holes distributed on its surface, and one side of the ceramic cover is fixedly connected to the corresponding part of the ring frame via an L-shaped block.

[0009] Preferably, a ceramic terminal block is provided in the middle of the ceramic cover.

[0010] Preferably, the transmission ratio between gear two and gear one is 1:2.

[0011] Compared with the prior art, the advantages of this utility model are as follows: by driving the heat radiation steel pipe connected by gear two and gear one through four motors, two sets of material equalization spiral blades with different spiral directions are rotated, achieving the effect of multi-directional synchronous mixing of materials, increasing the diversity of material mixing and flow direction, and at the same time, the electromagnetic heating induction coil heats the heat radiation steel pipe, which can not only heat the materials, but also prevent the materials from stagnating by means of the rotation of the material equalization spiral blades, ensuring the uniformity of the overall heating of the materials, and the heating and mixing speed is fast.

[0020] Please see Figure 1-3 As shown, a modified polypropylene heating and mixing device includes a heat-radiating steel pipe 1, a uniform material spiral blade 2, and an electromagnetic heating induction coil 6. The four heat-radiating steel pipes 1 arranged in a ring are each equipped with a uniform material spiral blade 2, and the spiral directions of two uniform material spiral blades 2 located in symmetrical positions are consistent. An electromagnetic heating induction coil 6 is provided inside each heat-radiating steel pipe 1, and a gear 3 and a gear 4 located on the heat-radiating steel pipe 1 are meshed and connected to each other for transmission. The gear 4 is installed on the shaft end of a motor 7, and the top end of the heat-radiating steel pipe 1 is rotatably connected to the cover opening of a ceramic cover 8 through a bearing 5.

[0021] The heat radiation steel pipe 1 is rotatably installed at the corresponding position of the ring frame 10. The ring frame 10 can ensure the support for the rotation of the heat radiation steel pipe 1.

[0022] Four protruding plates are provided at the annular holes on the inner side of the ring frame 10, and each protruding plate is fixedly connected to the corresponding motor 7 so as to distribute and install the corresponding motors 7.

[0023] The ceramic cover 8 has ventilation holes 810 distributed on its surface, and one side of the ceramic cover 8 is fixedly connected to the corresponding part of the ring frame 10 through an L-shaped block 11. The ventilation holes 810 can prevent the thermal expansion of the heat radiation steel pipe 1 from causing it to burst.

[0024] Furthermore, a ceramic terminal block 9 is provided in the middle of the ceramic cover 8.

[0025] Furthermore, the transmission ratio between gear 4 and gear 3 is 1:2.

[0026] Compared with the existing ones, the difference is that: the heat radiation steel pipe 1, which is driven by four motors 7 and connected by gear 2 4 and gear 1 3, rotates, causing two sets of uniform material spiral blades 2 with different spiral directions to rotate, achieving the effect of multi-directional synchronous mixing of materials, increasing the diversity of material mixing and flow directions. At the same time, the electromagnetic heating induction coil 6 heats the heat radiation steel pipe 1, which can heat the materials and prevent material stagnation by means of the rotation of uniform material spiral blades 2, ensuring the uniformity of overall heating of materials, and the heating and mixing speed is fast.
