Problems solved by technology

The liquid dispensing device is widely used in the pharmaceutical processing industry. The traditional liquid dispensing device is mainly composed of a tank and a stirring device. It is necessary to prepare various required raw liquids in a certain proportion and then pour them into the liquid dispensing device for configuration. The use of this type of liquid dispensing device configuration is not only inaccurate in controlling the ratio of the raw liquid, but also has a single structure and is inconvenient to operate, so it is not suitable for large-scale pharmaceutical processing flow operations
[0003] The existing publication number is CN203777977U, a liquid dispensing tank for pharmaceutical processing, comprising a tank body and a frame installed at the bottom of the tank body, and feed ports and discharge ports respectively located at the upper and lower ends of the tank body. The tank is equipped with a mixing chamber and a liquid storage chamber, and a liquid opening is provided between the two chambers, and a liquid valve is provided on the liquid opening. In addition, there are flow valves on each feed nozzle, a controller and ingredient extraction place on the outside of the tank, and a liquid level detector in the liquid storage bin; the device structure is simple, and the liquid mixing efficiency is relatively high. Poor, and the flow statistics of the liquid are not accurate enough, which may easily cause liquid dosing errors and affect the subsequent pharmaceutical processing

Description

technical field [0001] The invention relates to the technical field of pharmaceutical processing equipment, in particular to a liquid dispensing device for processing pharmaceutical intermediates. Background technique [0002] Pharmaceutical intermediates are actually some chemical raw materials or chemical products used in the process of pharmaceutical synthesis. Such chemical products do not require a pharmaceutical production license and can be produced in ordinary chemical factories, as long as they reach a certain level , which can be used in the synthesis of medicines. The liquid dispensing device is widely used in the pharmaceutical processing industry. The traditional liquid dispensing device is mainly composed of a tank and a stirring device. It is necessary to prepare various required raw liquids in a certain proportion and then pour them into the liquid dispensing device for configuration. The use of this type of liquid dosing device is not only inaccurate in con...
