The purpose of the present invention is in view of the deficienciess of the prior art, providing a kind of three cartridge type sodium borohydride process units.
Technical scheme：It is of the present invention solve the problems, such as used by technical scheme be：A kind of three cartridge type sodium borohydride process units,
The reactor for being used to generate sodium borohydride including an active motor and three；Described active motor is arranged in a mounting seat；
And controller is additionally provided with mounting seat and can control active motor rotating speed start and stop；The screw rod of described active motor is pacified straight up
Dress, and driving gear is installed on screw rod；Agitator is provided with three reactors, the shaft end of agitator reaches reactor
Upper end, and driven gear is installed in shaft end；Three reactors are placed around active motor, and three reactor agitators
The driven gear of shaft end is respectively provided with to be meshed with the driving gear of active motor.
Preferably, being provided with feed pipe on three reactors, flow control is provided with the feed pipe
Meter, described flow control meter communicate with controller.
Preferably, exhausting pipeline is additionally provided with three reactors, and three exhausting pipelines are connected to a heat exchanger
On；And it is sequentially installed with temperature sensor and magnetic valve on three exhausting pipelines；Described temperature sensor and controller phase
Communication, and magnetic valve is controlled by the controller switch.
Preferably, external diameter of the external diameter of described driving gear more than driven gear, and the external diameter of three driven gears
Identical, described three reactors circular array placement centered on active motor.
Beneficial effect：The invention has the advantages that：
(1) process units of sodium borohydride of the invention drives a set of agitator different from a traditionally stirring motor
Design, but is separately provided an active motor, sets three reactors, and the agitator in three reactors is installed by axle portion
Driven gear drive stirring, three driven gears are meshed with driving gear, therefore an active motor being separately provided
The agitator in three reactors can be driven to stir simultaneously, increase production efficiency in the case of cost-effective；
(2) present invention is gradually dropped trimethylborate, temperature after reactor chemically reacts in the feed pipe of each reactor
When degree steeply rises, temperature sensor detection temperature on exhausting pipeline, when reaching designated value, controller controls the electricity of exhausting pipeline
Magnet valve reduces the temperature in reactor, and the heat in exhausting pipeline is entered eventually into heat exchanger, is heated with needs outer
Connect equipment and carry out heat exchange, reach the purpose of recovery heat；Controller can control the flow control meter on feed pipe again simultaneously
The instillation speed of trimethylborate is controlled, the temperature in reactor is reached normal value, to ensure the production efficiency of sodium borohydride.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is Fig. 1 top view.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is furture elucidated, and the present embodiment is with technical solution of the present invention
