Continuous extracting equipment and method for extracting medical stone by equipment

Abstract

The invention discloses continuous extracting equipment and method for extracting medical stone by the equipment. The continuous extracting equipment comprises a water inlet tube, a working extractingunit and an extracting solution discharging tube, and further comprises a standby extracting unit, wherein the water inlet tube, the working extracting unit and the extracting solution discharging tube are connected continuously; the working extracting unit comprises at least one extracting devices which are connected in series; the standby extracting unit comprises at least one extracting device, each extracting device comprises an extracting column and a detecting device, each extracting column is filled with an extracting raw material, and each detecting device is used for detecting expected parameters of an extracting solution which flows out of the corresponding extracting column; and when the number of the expected parameters detected by the detecting devices in the working extracting unit is lower than a preset value, each extracting device including the corresponding detecting device stops working, and the extracting devices in the standby extracting unit are connected to thetail end of the working extracting unit during operation. The equipment does not need to stop, but continuous product can be realized, the method for extracting the medical stone by the equipment is simple and efficient, and meanwhile, the stability of products is ensured.

Description

technical field [0001] The invention relates to an extraction device, in particular to a continuous extraction device and a method for extracting medical stones using the device. Background technique [0002] In the prior art, the preparation of mineral water by using medical stone usually adopts the soaking method, and the mass transfer process is improved and the yield is increased by using small-sized medical stone raw stone powder or granules and stirring. This method is generally intermittent operation. Whenever the dissolution effect of medical stone fails to meet the requirements, it needs to be stopped for replacement, resulting in suspension of production. For example, the Chinese utility model patent with the application number of 201220478448.0 discloses the online extraction of medical stone beneficial elements using extraction tanks and filter tanks. Since the raw materials used in each extraction tank of this utility model are different, there is bound to be re...

Problems solved by technology

This method is generally intermittent operation. Whenever the medical stone dissolution effect does not meet the requirements, it needs to be stopped for replacement, resulting in suspension of production.

For example, the Chinese utility model patent with the application number of 201220478448.0 discloses the online extraction of medical stone beneficial elements using extraction tanks and filter tanks. Since the raw materials used in each extraction tank of this utility model are different, there is bound to be replacement. When the filter material is suspended, the production line is suspended, and because the characteristics of the filter material in each extraction tank are different, the replacement cycle is also different, and there is also a lack of corresponding monitoring methods, which cannot guarantee the stability of the final product quality
