Description

Technical Field

[0001] The utility model relates to the technical field of distillation devices, in particular to a distributed distillation device. Background Art

[0002] Distillation is a separation process that utilizes the different volatilities of components in a mixture to separate them. In the production of pharmaceutical intermediates, the raw materials, intermediates, and crude products processed are almost always mixtures, and most of them are homogeneous systems. For further processing and use, these mixtures often need to be separated into relatively pure or nearly pure substances. Distillation is one of the important methods for separating homogeneous liquid mixtures.

[0003] After searching, in the prior art, publication number CN219815323U discloses a new type of distillation equipment, including a distillation tank body, the top of the distillation tank body is fixedly connected to an electric push rod, the output end of the electric push rod is fixedly connected to a scraper with one end extending to the inner side of the distillation tank body, the bottom of the distillation tank body is fixedly connected to a collecting box, the inner side of the collecting box is slidably connected to an impurity box with one end extending to the front side of the collecting box, and the bottom of the distillation tank body is fixedly connected to a cleaning pipe connected to the inner side of the impurity box. The device discharges the drug raw materials into the inner side of the distillation tank body through the feed pipe, and then starts distillation. After the distillation is completed, the drug liquid can be discharged into the discharge box for collection by starting the electromagnetic valve on the outside of the discharge pipe; after the distillation is completed, water is injected into the inner side of the distillation tank body through the feed pipe, and then the electric push rod is started to extend and retract to drive the scraper to move up and down. The scraper moves up and down on the inner side of the distillation tank body to scrape off impurities on its inner wall. After scraping clean, the impurities can be discharged into the impurity box for collection by opening the electromagnetic valve on the outside of the cleaning pipe; by holding the handle on the front side of the impurity box and pressing the movable rod, the movable rod drives the slider to move backward, the spring is forced to contract, and at the same time, the clamping rod slides downward on the inner side of the slide groove and retracts into the interior of the impurity box, so that the impurity box can be taken out and its interior can be cleaned.

[0004] However, the device and the prior art still have the following defects:

[0005] Although the existing distillation device can distill the raw materials and clean the inside of the device, it can only separate one component and cannot be used for distributed distillation of multiple components. When multiple components need to be extracted, the raw materials need to be distilled multiple times, which has poor functionality and low practicality. Utility Model Content

[0041] Working principle: First, pour the raw materials into the lower cylinder 1, select the number of upper cylinders 2 according to the type of ingredients to be extracted, and assemble the upper cylinder 2 and the lower cylinder 1 together through the connector 3. After the assembly is completed, connect the wires of each electronic component, and turn on the power of the device.

The first component will remain in the bottom upper cylinder 2, that is, the extraction of the first component is completed, and the remaining components are extracted in turn. After the required components are extracted, the solenoid valve 3 is opened, and the components are discharged separately through the drain pipe 8, thereby realizing distributed distillation of the device. When cleaning the device, only the connector 3 needs to be disassembled, which is very convenient to use.
