Feeding device for conveying white carbon black raw material into kettle

Abstract

The invention discloses a feeding device for conveying a white carbon black raw material into a kettle. The feeding device comprises a reaction kettle which is positioned in a pit, wherein a belt type conveying device is arranged on the ground nearby the pit; a sliding groove is obliquely formed between the belt type conveying device and the reaction kettle; the belt type conveying device comprises a conveying belt which is annularly arranged; the conveying belt comprises a conveying belt body and conveying belt stop edges which are arranged on two sides of the conveying belt body; the conveying belt body and the conveying belt stop edges on the two sides of the conveying belt body form a conveying belt with a U-shaped section; one end of the sliding groove is positioned below the conveying belt, and the other end of the sliding groove is lapped to a charging hole of the reaction kettle; a crushing device and a vibration device are arranged on the sliding groove. The feeding device for conveying the white carbon black raw material into the kettle is high in efficiency, stable and reliable, and has the time-saving and labor-saving effect.

Description

technical field [0001] The invention relates to the field of transportation, in particular to a feeding device for feeding white carbon black raw materials into a kettle. Background technique [0002] White carbon black, also known as hydrated precipitated silica, is a white amorphous fine powder, and has a series of advantages such as high temperature resistance, non-combustibility, and good electrical insulation. It is mainly used as a reinforcing agent for rubber and is an important silicon It is an inorganic functional powder material. Most of them are prepared by traditional precipitation method in China. They use sodium silicate (sodium silicate) solution and sulfuric acid as raw materials, adjust the pH value at a certain temperature to obtain silica precipitation, and then press the slurry from the reactor. The filter is filtered and washed to remove sodium sulfate and impurities, and then the obtained filter cake is liquefied into a paste slurry by high-speed stirr...

Problems solved by technology

[0003] In order to facilitate transportation and storage, the commonly used agaricine is a solid particle produced by a dry process, which is dissolved in a reactor at a certain temperature and pressure and transformed into a liquid agaricine of the required specification. In the existing process, the reaction Adding sodium hydroxide to the kettle is done manually. This traditional feeding method requires a lot of labor, time-consuming, labor-intensive, high cost and low efficiency.
