Description

Technical Field

[0001] The utility model relates to the technical field of solid sulfur-containing silane coupling agent production, in particular to a feeding and conveying device for the production of a silicon 69 and carbon black mixture. Background Art

[0002] Silicon 69 is a sulfur-containing silane coupling agent that can significantly improve the wear resistance and anti-aging properties of rubber tires. Carbon black is a very important rubber filler with a high specific surface area and adsorption capacity, which can significantly enhance the hardness, wear resistance and oil resistance of rubber. Silicon 69 combined with carbon black can improve the dispersion of carbon black in rubber. Silicon 69 and carbon black can mutually enhance the cross-linking effect on rubber to form a more stable and uniform network structure, thereby improving the tensile strength, tear strength, wear resistance, etc. of rubber. At the same time, it can also reduce the viscosity of the rubber and improve the processing performance.

[0003] In the traditional silicon 69 and carbon black mixing process, carbon black mainly adopts the negative pressure feeding process. When carbon black is fed and fed, dust is easily generated on site, which has a great impact on the health of on-site workers. At the same time, the dust of carbon black will also cause the loss of raw materials. The silicon 69 and carbon black mixture adopts screw extrusion granulation and screw conveying. During the conveying process, due to the characteristics of the product itself, the inner wall of the pipeline is easy to stick to the material, causing the equipment pipeline to be blocked, and the production efficiency is low. The product after conveying is easy to be damaged by screw extrusion, which reduces the product quality. In addition, the coarse particles of silicon 69 and carbon black mixture generated in the production process cannot be handled, which increases the production cost. Utility Model Content

[0029] Reference Figure 1 A feeding and conveying device for the production of a silicon 69 and carbon black mixture comprises a carbon black unpacking machine 1. After the carbon black is unpacked, it is automatically transported to a mixer 4 through a first vacuum feeder 2 pipeline. At the same time, the vent at the upper end of the silo of the carbon black unpacking machine 1 is connected to an induced draft dust collector 11 through a pipeline to reduce the leakage of carbon black during the carbon black feeding process. The carbon black powder collected by the induced draft dust collector 11 will be returned to the system for continued use. Then the silicon 69 is discharged through a dripping tank and dripped into the mixer 4 to be mixed with the carbon black by an adjusting valve to automatically control the flow rate. The mixed silicon 69 and carbon black in the mixer 4 enter an agitator 5 for granulation. Then, multiple agitators 5 transport the granulated silicon 69 and carbon black to a silicon 69 and carbon black mixture buffer silo 7 through a second vacuum feeder 6. Then, the granulated silicon 69 and carbon black mixture in the buffer silo 7 enters a vibrating screen 8 through a high head difference for screening. Finally, the screened silicon 69 and carbon black mixture particles enter a finished product silo 10 for packaging.

[0030] Furthermore, the mixer 4 is below the first vacuum loader 2, and the outlet of the first vacuum loader 2 is provided with an automatic positioning docking cylinder device 12, and the feed port of the mixer 4 is provided with an automatic pneumatic docking butterfly valve 13.
