Description

Technical Field

[0001] The utility model belongs to the technical field of silicone rubber, and specifically relates to a filtering structure and a silicone rubber reaction device thereof. Background Art

[0002] In the preparation process of silicone rubber, dimethylcyclosiloxane is used as the main raw material, and methyl vinyl tetracyclosiloxane accounting for one-thousandth to four-thousandths of dimethylcyclosiloxane is added. Under the action of a catalyst, dimethylcyclosiloxane undergoes an open-chain polymerization reaction to generate high-molecular linear dimethylpolysiloxane, and methyl vinyl tetracyclosiloxane also undergoes an open-chain polymerization reaction to generate high-molecular linear methyl vinyl polysiloxane, thereby obtaining raw methyl vinyl silicone rubber.

The first stirring rod and the second stirring rod are symmetrically distributed with the main rod as the axis, and can fully stir the silicone rubber mixture.

[0005] However, before the reaction of silicone rubber, the raw materials need to be filtered. At present, most filtering is carried out by a simple filter screen. The filter screen will become blocked, resulting in a weakened filtering effect. At the same time, a large amount of raw materials accumulate on a single filter screen, resulting in the situation that due to the surface tension of the liquid (fluid), the liquid (fluid) will adhere to the surface of the filter screen, resulting in a low filtering effect.

[0006] In view of this, the present utility model is specifically proposed. Content of the Utility Model

The fastener includes but is not limited to a bolt. The raw materials are sent into the space formed by the partition in the filtering box 1 through the first feed pipe 11. The raw materials in the space formed by the partition are forced to move upward by the continuous force of the raw material entering and are filtered through the filtering pipe 3. The filtering pressure of a single filter screen is shared by the pipeline-type filtering method of multiple groups of filtering pipes 3. At the same time, the principle is filtered in a multi-threaded manner by the integration of multiple groups of filtering pipes 3, thereby improving the filtering efficiency.

At the same time, the plurality of groups of filter tubes 3 are integrated to perform multi-threaded filtration at the same time, thereby improving the filtration efficiency. At the same time, the buoyancy is provided for the cleaning plate 4 to move upward through the float 41, thereby driving the internal cleaning brush 42 to rub against the surface of the filter tube 3, thereby removing impurities in the filter tube 3, and then While achieving a high filtering effect, it prevents excessive accumulation of impurities in the filter tube 3, which would lead to a reduction in the filtering effect.
