Filtering and settling device for ultrasonic extracting machine set

Abstract

The invention discloses a filtering and settling device for an ultrasonic extracting machine set. A filter pipe extends spirally from top to bottom; at least one filter element is arranged in the filter pipe; a liquid collecting device is arranged at the upper end of the filter pipe; a pipe opening at the lower end extends to one end of a settling pond; the settling pond is divided into an upper settling chamber and a lower liquid containing chamber by a filter plate arranged in the settling pond; a filter mesh is arranged above the filter plate, is bent, and is perpendicular to the filter plate; the direction of a protrusion end of the filter mesh is directed at the lower end of the filter plate. By the spiral filter pipe in which the filter element is arranged, a diversion effect is achieved, the flowing path of a filtrate is extended, and the filtering time of the filtrate is increased; the filtrate is further filtered by the bent filter mesh arranged on the filter plate in a flowing process on the filter plate; according to the device, multilayer filtering is realized; the filtrate settles in the liquid containing chamber; the filtering effect is good; the impurities are few.

Description

technical field [0001] The invention relates to the field of biomechanics, in particular to a filter and sedimentation device used in an ultrasonic extraction unit. Background technique [0002] Ultrasound is a sound wave with a frequency higher than 20,000 Hz. It has good directionality, strong penetrating ability, and is easy to obtain concentrated sound energy. It can travel far in water and can be used for distance measurement, speed measurement, cleaning, welding, gravel, and sterilization. Wait. [0003] When the ultrasonic waves propagate in the liquid, due to the violent vibration of the liquid particles, small cavities will be generated inside the liquid. The rapid expansion and closure of these small cavities will cause violent collisions between the liquid particles, resulting in a pressure of thousands to tens of thousands of atmospheres. The violent interaction between the particles will cause the temperature of the liquid to rise suddenly, which plays a very ...

Problems solved by technology

[0004] Ultrasonic extraction is to use the multi-level effects such as strong cavitation effect, mechanical vibration, disturbance effect, high acceleration, emulsification, diffusion, crushing and stirring effect produced by the above-mentioned ultrasonic radiation pressure to increase the frequency and speed of material molecular motion, increase Solvent penetration, so as to accelerate the target components into the solvent, and promote the extraction process. At present, ultrasonic extraction technology has been used to extract natural products from Eucommia ulmoides to produce Eucommia rubber and other products. In the extraction technology, filtration is an important link in the extraction process. At present, the existing sedimentation equipment has a single sedimentation method, which cannot achieve multi-layer filtration and sedimentation. The filtration is not thorough enough, there are many impurities, and the sedimentation efficiency is low. Some centrifugal filtration sedimentation devices are used to filter sedimentation with high quality, but the equipment is expensive and the cost is relatively high. High, not suitable for industrial mass production
