Agitating test device

Abstract

The invention provides an agitating test device, belongs to the technical field of pharmaceutical chemicals, and the agitating test device is used for solving the problems that the existing agitating test has no special device, is more inconvenient and has inaccurate detection result and large errors. The agitating test device comprises a supporting frame and a vertically-arranged agitating input shaft; the agitating input shaft is positioned on the supporting frame; the lower end part of the agitating input shaft is fixedly connected with a connecting piece which is fixedly connected with a ventilating agitating rod assembly; the supporting frame is fixedly connected with a motor; the rotary shaft of the motor is connected with the upper end of the agitating input shaft; and the agitating test device further comprises an air inlet mechanism, an air flow detection element and a rotary speed control unit; the air inlet mechanism is provided with an air inlet pipe and can be communicated with the ventilating agitating rod assembly; the air flow detection element can detect an air flow state in the air inlet mechanism; and the rotary speed control unit can control the high and low rotary speeds of the motor. The agitating test device has the advantages of simplicity and convenience for operation, labor-saving property, accurate detected data result and smaller errors.

Description

technical field [0001] The invention belongs to the technical field of medicine and chemical industry, and relates to a test and detection equipment for medicine and chemical industry, in particular to a stirring test device. Background technique [0002] In the process of modern industrial production, physical or chemical reactions are often required between substances. The physical and chemical reactions of substances are generally carried out in the reaction kettle. During the reaction, the medium participating in the reaction needs to be stirred to make it fully mixed and improve the efficiency of the reaction. Regarding the reaction substances composed of gas and liquid or gas, liquid and solid, the traditional stirring method usually adopts heterogeneous stirring and self-priming stirring. During the stirring process of heterogeneous stirring, the size of the contact area of ​​the gas and liquid phase directly affects the reaction rate, which easily leads to gas dispe...

Problems solved by technology

Therefore, before production, it is necessary to test and detect the critical value of the stirring speed of each reactor at different liquid level heights. At present, there is no stirring test device specially used to detect the critical value of the stirring speed. Judging by the naked eye, if small bubbles are formed in the stirred liquid, it means that it has formed self-absorption. At this time, the stirring speed is a critical value, and the detection result is not accurate, the error is large, and the detection is also inconvenient
