Description

Technical Field

[0001] The utility model relates to the technical field of paramenthane hydrogen peroxide production, and more specifically, to a cleaning device for paramenthane hydrogen peroxide production. Background Art

[0002] P-menthane hydrogen peroxide is a chemical substance, which is mainly used as an initiator for organic polymerization reactions, such as an initiator for styrene-butadiene rubber, a cross-linking agent for unsaturated polyesters, and is also used to prepare fragrances, etc. When producing p-menthane hydrogen peroxide, a reactor is often used to mix and react it, and the reactor needs to be cleaned after use.

[0003] After searching, the utility model patent with announcement number CN215466813U discloses a cleaning device for producing menthane with hydrogen peroxide, including a reactor, support legs and a sealing cover. A cleaning structure is arranged on the top of the reactor, and the cleaning structure includes a connecting rod. The surface of the connecting rod is engaged with the reactor, and the bottom of the connecting rod is slidably connected to two moving blocks. A first screw is rotatably inserted into the side wall of the connecting rod. By setting up a cleaning structure, the patent makes it convenient to fix the device on the top of the reactor and to clean reactors of different sizes. Mechanized cleaning saves labor and has a fast cleaning speed.

[0004] However, the above patents still have the following shortcomings: it is not convenient to continuously spray water into the reactor during cleaning, and water can only be injected into the reactor first, and then the device is used for cleaning, which affects the convenience of cleaning; after cleaning the reactor, it is not convenient to dry the residual water stains in the reactor.
