Problems solved by technology

If the solvent is not added in time when the viscosity is too high, the medicine will form hard lumps, which will affect the production of medicines. In severe cases, it is necessary to use tools to break the hard lumps before continuing to produce
In addition, if the viscosity is too high, the motor of the stirring pot will burn out, and the motor needs to be repaired and replaced, which will increase equipment costs and reduce production efficiency

Embodiment 1

[0028] This embodiment describes a detection and alarm circuit for a stirring pot for pharmaceutical production, such as figure 1 Shown: The circuit includes a power supply module, a signal module, a lower limit module, an upper limit module, a control module and an alarm module.

[0029] Among them, the signal module is used to detect the motor current of the stirring pot, and convert the information of the motor current into an initial voltage signal. The lower limit module and the upper limit module are respectively used for converting the initial voltage signal into a lower limit voltage signal and an upper limit voltage signal. The control module is used to compare the lower limit voltage signal and the upper limit voltage signal with the lower limit set value and the upper limit set value respectively, and control the on-off of the alarm module. The alarm module is used for alarming when the viscosity of the medicine is too high.

[0030]Specifically, the signal module...

Abstract

The invention provides a stirring pot detection alarm circuit for pharmaceutical production. The stirring pot detection alarm circuit is characterized by comprising a power supply module, a signal module, a lower limit module, an upper limit module, a control module and an alarm module, wherein the signal module is used for detecting the motor current of a stirring pot and converting the motor current into an initial voltage signal; the lower limit module and the upper limit module are used for converting the initial voltage signal into a lower limit voltage signal and an upper limit voltage signal respectively; the control module is used for comparing the lower limit voltage signal and the upper limit voltage signal with a lower limit setting value and an upper limit setting value respectively and controlling the switch-on and switch-off of the alarm module. The circuit can monitor the viscosity of pharmaceuticals in the stirring pot in real time, can improve the production efficiency and quality of the pharmaceuticals, is simple, reliable, low in cost, high in commonality and convenient to use, and can avoid disturbing influence.

Description

technical field [0001] The invention relates to the field of equipment for pharmaceutical production, and more specifically relates to a detection and alarm circuit for a stirring pot for pharmaceutical production. Background technique [0002] In the production process of pharmaceuticals, such as the production process of sulfa drugs, it is necessary to stir the chemical raw materials for a long time. Sulfa drugs include sulfamethazine, sulfamethazine sodium, sulfamethazine, sulfamethazine sodium, sulfamethazine, sulfamethazine sodium, sulfamethoxine, sulfamethoxazole, sulfamethoxazole sodium, Trimethoprim lactate, sulfamidine, crystalline sulfa, and more. [0003] Stirring can make the formula raw materials mix evenly and fully react. However, during the stirring process, the viscosity of the medicine keeps rising. When the viscosity is too high, workers need to add solvents for dilution to reduce the viscosity so that the stirring can continue normally. If the solvent ...
