Description

Technical Field

[0001] The utility model relates to the field of reaction kettles, in particular to a reaction kettle for preparing cable materials. Background Art

[0002] Cable materials are the main raw materials for manufacturing cables. They are used to manufacture the insulation layer, sheath layer and other parts of the cables. Cable materials mainly include the following: insulation materials, sheath materials, and conductor materials. The insulation material is polyvinyl chloride, which is a common insulation material. When polyvinyl chloride is produced, it needs to be heated in a reactor and mixed with other additives. A heating jacket is often used for heating.

[0003] When the heating jacket is used, the inner wall of the reactor and the center of the reactor have different temperatures at different locations due to their different distances from the heating source, which causes the polyvinyl chloride to be heated unevenly and even to become sticky.

[0004] Therefore, it is necessary to propose a reactor for preparing cable materials to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a reactor for preparing cable materials, so as to solve the problem that the inner wall and the center of the reactor have different temperatures at different positions due to different distances from the heating source, which leads to uneven heating of polyvinyl chloride and even the occurrence of paste when the polyvinyl chloride is heated.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reactor for preparing cable materials, comprising a reactor body and a reaction tank arranged inside the reactor body for carrying the cable materials, wherein two stirring blades for stirring the cable materials are rotatably arranged inside the reaction tank, and a reverse material blade is fixedly arranged at the end of the stirring blade, and the reverse material blade is arranged obliquely;

[0007] A stirring rod is rotatably provided inside the reaction tank, and a plurality of transmission rods are fixedly provided outside the stirring rod, and one end of the transmission rod at the lower end is fixedly connected to one end of a corresponding stirring blade;

[0008] A fixing sleeve is arranged in the reaction tank, the outer side of the fixing sleeve is also fixedly connected to one end of the stirring blade, and a dispersion plate is fixedly arranged on the upper end of the fixing sleeve.

[0009] Preferably, a spiral blade is fixedly provided on the outer side of the stirring rod, and a feed slope is provided on the end of the spiral blade.

[0010] Preferably, the transmission rod at the upper end is fixedly connected to the inner wall of the fixing sleeve.

[0011] Preferably, the upper end of the dispersion plate is inclined.

[0012] Preferably, one end of the transmission rod is configured in a conical shape.

[0013] Preferably, an output device is fixedly provided at the upper end of the reactor body, the output end of the output device is fixedly connected to one end of a stirring rod, a plurality of connecting joints are provided on the outside of the reaction tank, a heating jacket is also provided on the outside of the reaction tank, a display meter is provided on the outside of the reactor body, and a plurality of support frames are fixedly provided on the outside of the reactor body.

[0014] Technical effects and advantages of the utility model:

[0015] 1. Through the shape setting of the reverse material blade, when the stirring rod stirs and accelerates the mixing of the cable material, the material close to the inner wall of the reaction tank can be moved closer to the inside of the reaction tank, preventing the material from being on the inner wall of the reaction tank for a long time, causing the problem of uneven heating temperature of materials at different positions;

[0016] 2. By setting the spiral blades, the material in the center of the reaction tank can make room for the material coming back, so that the material can flow and the material in the center of the reaction tank and near the inner wall can be mixed to ensure that the materials at different positions are heated evenly and the materials at two locations are double treated.

A plurality of support frames 3 are fixedly provided on the outside of the reactor body 1, which are convenient for placing the reactor body 1. Two stirring blades 5 for stirring the cable material are rotatably provided inside the reaction tank 101, and the stirring blades 5 are arranged in an arc shape. A reverse material blade 6 is also fixedly provided at the end of the stirring blade 5, and the reverse material blade 6 is arranged in an inclined manner, which is convenient for bringing the material toward the middle of the stirring rod 4;

[0025] A stirring rod 4 is rotatably provided inside the reaction tank 101, and the output end of the output device 102 is fixedly connected to one end of the stirring rod 4. A plurality of transmission rods 10 are fixedly provided outside the stirring rod 4, and one end of the transmission rod 10 at the lower end is fixedly connected to one end of the corresponding stirring blade 5;

[0026] A fixing sleeve 8 is provided in the reaction tank 101 , and a dispersion plate 12 is fixedly provided on the upper end of the fixing sleeve 8 . The upper end of the dispersion plate 12 is inclined to facilitate the materials to directly approach the inner wall of the reaction tank 101 .
