Description

Dried orange peel essential oil filtering and purifying device Technical Field The utility model relates to the field of extraction of essential oil, in particular to an improvement of a tangerine peel essential oil filtering and purifying device. Background At present, residual peel pectin and the like are generally required to be removed by adopting modes such as precipitation and the like after the extraction of the tangerine peel essential oil is finished. This extraction requires a long standing time, and of course, filtration may be performed by some filtration means. When filtering, a filter screen is usually used for filtering, however, in the filtering process, because the dried orange peel powder is used in the extraction, the filtering time is not long, and the filtering holes on the filter screen are blocked by the dried orange peel powder, pectin and the like, so that the filtering efficiency is affected, and the filtering time of the dried orange peel essential oil is increased. The common countermeasure is that the dried orange peel essential oil is purified by multiple times of filtration with different filtration precision each time. The filtering and purifying efficiency is low and the filtering time is long. Disclosure of utility model In order to overcome the defects in the prior art, the utility model provides a tangerine peel essential oil filtering and purifying device. The utility model adopts the following technical scheme that the tangerine peel essential oil filtering and purifying device comprises a filtering tank, wherein the filtering tank is divided into an upper tank and a lower tank by a partition board, a filtrate outlet is formed in the partition board and is communicated with the upper tank and the lower tank, a filtering component and a scraping component are arranged in the upper tank, the edge of the filtering component is fixed on the inner wall of the upper tank, the scraping component is contacted with the filtering component and rotates to drive the edge of the scraping component to scrape the filtering component; The side wall of the lower tank is provided with a negative pressure hole, the negative pressure hole is communicated with a negative pressure component through a pipeline, and when the negative pressure component is started, the lower tank forms negative pressure. The filter component comprises a frame and a filter membrane, the edge of the filter membrane is fixed with the inner wall of the upper tank through the frame, the upper part of the filter membrane is used for placing essential oil stock solution, and the edge of the scraping component is abutted to the surface of the filter membrane. The scraping assembly comprises a scraping shaft, the scraping shaft extends along the axial direction of the upper tank and is in contact with the filter membrane, a scraping piece is sleeved on the scraping shaft, the scraping piece rotates along with the scraping shaft, and the edge of the scraping piece is in contact with the filter membrane. The scraping piece comprises a pair of scraping rods, the pair of scraping rods are fixedly connected to the scraping shaft, the scraping rods extend towards the inner wall of the upper tank, and one side, in contact with the filter membrane, of each scraping rod is provided with a scraping adhesive tape. The frame comprises a pressing plate, an annular table is arranged on the inner wall of the upper tank, the edge of the filter membrane is arranged on the annular table, and the pressing plate is abutted to the filter membrane and fixed with the annular table.
