Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of food and medicine and chemical industry liquid filtration, and specifically relates to an efficient and stable extract liquid filter. BACKGROUND

[0002] In the field of food, medicine and chemical industry, the filtering quality and efficiency of the extract liquid play a key role in the final quality of the product and the production efficiency. With the development of the industry, the performance requirements for the extract liquid filter are becoming increasingly stringent.

[0003] Most of the traditional extract liquid filters are basket type filters. This type of filter has inherent defects. Its filtering principle is relatively simple, and it usually relies on a single filter medium and a relatively simple structure design to achieve the preliminary filtering function. In actual application, the basket type filter is prone to incomplete filtering. Since the filtering precision of the filter medium is limited, the trapping capacity for some small particle impurities and dissolved impurities is insufficient, so that part of the impurities can penetrate the filter layer and enter the subsequent production link, which not only affects the purity and quality stability of the product, but also may cause damage to the subsequent processing technology and equipment.

[0004] Moreover, the basket type filter is prone to clogging. In the long-term filtering process, impurities will gradually accumulate on the surface of the filter medium. Since it lacks an effective self-cleaning mechanism, as the impurities continue to accumulate, the filtering channel will become narrower and narrower until it is completely clogged. Once clogging occurs, not only will the filtering efficiency decrease sharply, but the entire filtering process will also be forced to stop, which requires a lot of time and manpower for cleaning and maintenance, seriously affecting the continuity of production and economic benefits.

[0005] In addition, for some specific extract liquids, such as heat-sensitive solutions in chemical synthesis, temperature is one of the key factors affecting the filtering effect. However, the traditional basket type filter lacks effective temperature control means. When the environmental temperature is low, the viscosity of the extract liquid may increase significantly, and the solute may even crystallize and precipitate, which will greatly increase the difficulty of filtering and even clog the filter medium, making the filtering process unable to proceed normally. On the contrary, if the temperature is too high, the effective components in some heat-sensitive extract liquids may degrade or denature, thereby seriously reducing the quality of the product. This filtering problem caused by temperature factors is difficult to solve effectively in traditional filters, limiting their application in the production of some high-end products that are sensitive to temperature.

[0006] In summary, the traditional basket type extract liquid filter has many shortcomings in filtering effect, anti-clogging performance and temperature adaptability, and it is difficult to meet the urgent needs of the modern food and medicine and chemical industry for efficient, stable and high-quality filtration. There is an urgent need for a new extract liquid filter with better comprehensive performance to solve these problems.
