Mixing in the production process of the clinical moving medicines such as sense six is anti-, the anxious pin of variola, cephalo, skin medicine, need to use lavo-ofloxacin hydrochloride.Lavo-ofloxacin hydrochloride is applicable to the infection such as infection in respiratory system, urinary system infection contamination, genital system infection, skin soft-tissue infection, enteric infection.In the technique of synthetic hydrochloric acid lavo-ofloxacin, there is stirring, the process that simultaneously also will heat.Existing technique adopts manual operation more, in stirring, also will heat, and not only stir speed (S.S.) is inhomogeneous, and heating and temperature control comparatively bothers, inefficiency, and waste a large amount of human costs, can not meet the demand of lean production.
Utility model content
The utility model provides a kind of synthetic agitating heater of clinical moving medicinal hydrochloric acid lavo-ofloxacin, have and stir and heating function, and can show and control stir speed (S.S.), heating-up temperature, and be designed with batching and drip mouth and solution outlet, can carry out therein multistep reaction, not only control synthesis condition, also improved combined coefficient.
In order to realize the purpose of this utility model, intend adopting following technology:
The synthetic agitating heater of clinical moving medicinal hydrochloric acid lavo-ofloxacin, comprise stirred vessel (1), it is characterized in that: the outer heat insulation surrounding layer (2) that is provided with of described stirred vessel (1), heat insulation surrounding layer (2) and stirred vessel (1) outer wall form the steam chest (3) of sealing, stirred vessel (1) top is provided with insulation cover (4), and stirred vessel (1) bottom is provided with solution discharge pipe (7); One end of described steam chest (3) is provided with steam inlet duct (5), and the other end is provided with exhaust duct aperture (6); Described stirred vessel (1) inside is provided with temperature sensor (13) and runs through the dwang (9) of insulation cover (4), dwang (9) upper end connection of rotating motor (12), rotary electric machine (12) connects lower end and is fixed with gangbar (10), under gangbar (10), be fixed with stirring rod (11), temperature sensor (13) is connected respectively controller (14) with rotary electric machine (12).
Further, described steam inlet duct (5) is provided with air inlet switch (8).
Further, described insulation cover (4) is provided with batching and drips mouthful (16).
Further, described solution discharge pipe (7) is provided with draining switch (17).
Further, described controller (14) is also connected to display unit (15).
Further, described air inlet switch (8) connects controller (14).
Further, described draining switch (17) connects controller (14).
The beneficial effects of the utility model are:
1, by the rotation of controller control motor, thereby make the rotation of dwang controlled, thereby it is controlled to realize stirring, particularly stir speed (S.S.) is controlled;
2, gather the temperature in stirred vessel by temperature sensor, feed back to controller, by controller control air inlet switch, thus steam regulation air inlet degree, and then realize the control of heating-up temperature;
3, be designed with batching and drip mouth and solution outlet, can carry out therein multistep reaction;
4, the utility model has not only been controlled synthesis condition, has also improved combined coefficient.
Brief description of the drawings
Fig. 1 shows the utility model structural representation.
Detailed description of the invention
As shown in Figure 1, the synthetic agitating heater of clinical moving medicinal hydrochloric acid lavo-ofloxacin, comprises stirred vessel (1).
The outer heat insulation surrounding layer (2) that is provided with of stirred vessel (1), heat insulation surrounding layer (2) and stirred vessel (1) outer wall form the steam chest (3) of sealing, one end of steam chest (3) is provided with steam inlet duct (5), the other end is provided with exhaust duct aperture (6), steam inlet duct (5) is provided with air inlet switch (8), and air inlet switch (8) connects controller (14).
Stirred vessel (1) top is provided with insulation cover (4), and insulation cover (4) is provided with batching and drips mouthful (16).
Stirred vessel (1) bottom is provided with solution discharge pipe (7), and draining switch (17) connects controller (14).
Stirred vessel (1) inside is provided with temperature sensor (13) and runs through the dwang (9) of insulation cover (4), dwang (9) upper end connection of rotating motor (12), rotary electric machine (12) connects lower end and is fixed with gangbar (10), under gangbar (10), be fixed with stirring rod (11), temperature sensor (13) is connected respectively controller (14) with rotary electric machine (12).
