Extraction device with function of separating and screening phenolic harmful substances

Abstract

The invention relates to the field of extraction devices with function of separating and screening phenolic harmful substances, in particular to an extraction device with function of separating and screening phenolic harmful substances. The device comprises a storage mechanism, a mounting mechanism, a fixing mechanism, a main body mechanism and a sealing mechanism. An operator pulls the fixing mechanism, so that the storage mechanism is fixed and limited when the fixing mechanism slides in the main body mechanism, the situation that the operator inhales a solvent into the mouth and the nose by mistake to cause poisoning in the extraction process is prevented, the health of the operator is protected to a certain extent, and the use effect of the extraction device is favorably improved. When the storage mechanism and the main body mechanism are fixed, the storage mechanism abuts against the sealing mechanism, so that a solvent in the storage mechanism flows into the main body mechanism through a gap part between the storage mechanism and the sealing mechanism, the device can conveniently extract the solvent, and meanwhile, the step that an operator needs to repeatedly add the solvent is also prevented, and the use efficiency of the device is improved to a certain extent.

Description

technical field [0001] The invention relates to the field of extraction devices with separation and sieving of phenolic harmful substances, in particular to an extraction device with separation and sieving of phenolic harmful substances. Background technique [0002] Phenol is referred to as phenol for short, also known as carbolic acid, slightly acidic (corrosive), can volatilize at room temperature, emit a special pungent odor, and turn pink in the air. Low concentrations of phenol can denature proteins, while high concentrations can precipitate proteins. It has a strong corrosive effect on the skin and mucous membranes, and can also inhibit the central nervous system or damage the liver and kidney functions. Aqueous solutions are more easily absorbed through the skin than pure phenol, while emulsions are more easily absorbed. Most of the inhaled phenol stays in the lungs and will be excreted soon after stopping exposure. [0003] However, when the traditional extractio...

Problems solved by technology

[0003] However, when the traditional extraction device is separating harmful substances, the solvent is directly exposed to the air. The operator may inhale the harmful substances into the mouth and nose during the operation, which poses a certain safety hazard and is not conducive to protecting the operation to a certain extent. The health of personnel; in addition, in the process of extraction, the operator also needs to add solvent repeatedly, the operation steps are cumbersome and not conducive to improving the work efficiency of the operator, and to a certain extent, it is also not conducive to improving the efficiency of the extraction device
