Description

Technical Field

[0001] The utility model relates to the technical field of rubber auxiliaries production, in particular to an automatic feeding device for producing rubber auxiliaries. Background Technique

[0002] The origin of rubber auxiliaries dates back to the vulcanization of natural rubber. After more than eighty years of research, it was not until the 1920s and 1930s that the rubber auxiliaries basically formed a system with the industrialization of the basic varieties of vulcanization accelerators, 2-mercaptobenzothiazole and its sulfenamide derivatives, as well as p-phenylenediamine antioxidants. During the stable period of rubber auxiliaries, the output of the two main types of organic auxiliaries, vulcanization accelerators and antioxidants, was approximately 4% of the raw rubber consumption.

[0003] In the rubber injection agent production equipment, there is a feeding mechanism. For example, in a rubber auxiliaries production equipment with the patent publication number CN117323887A, through the arranged mixing component, nitrogen is filled into the dilute sulfuric acid in the liquid material tank through a gas guide pipe to generate bubbles in the dilute sulfuric acid liquid, and then the pressure in the liquid material tank is adjusted through a pressure valve to make the liquid material tank in a high-pressure state. At this time, the dilute sulfuric acid bubbles will be discharged from the micropores of the spray pipe. At the same time, sodium nitrite is sent into the mixing tank from the material guide cylinder. The dilute sulfuric acid bubbles are composed of dilute sulfuric acid. When the dilute sulfuric acid bubbles contact sodium nitrite, a primary mixing occurs. The water droplets after the rupture of the dilute sulfuric acid contact sodium nitrite again for a secondary mixing, which can ensure the full contact of the dilute sulfuric acid bubbles and sodium nitrite, shorten the reaction oxidation time, and improve the work efficiency.

[0004] Since the feeding device of this device is a powder box, its feeding accuracy is difficult to control and its practicability is poor. Content of the Utility Model
