Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 is the schematic diagram of the present invention.
In figure：Reactive tank 1, underflow opening 2, downflow weir 3, agitating paddle 4, ore pulp charge door 5, hydrochloric acid charge door 6, discharging opening 7,
Drain mouth 8, bleeding point 9, baffle plate 10.
Embodiment
As shown in figure 1, a kind of reaction of high order slot device of hydrochloric acid method preparing phosphoric acid, including reactive tank 1, underflow opening 2, overflow
Weir 3, agitating paddle 4, ore pulp charge door 5, hydrochloric acid charge door 6, discharging opening 7, mouth 8 and bleeding point 9 are drained, the reactive tank 1, which divides, is
Multistage, is separated by the baffle plate 10 and downflow weir 3 that are arranged alternately between reactive tanks 1 at different levels and each bottom of baffle plate 10 is provided with
Underflow opening 2；Agitating paddle 4 and bleeding point 9 are equipped with every first order reaction groove 1, first order reactive tank is provided with charge door, most
Rear stage reactive tank is provided with discharging opening 7 and drains mouth 8.
The charge door includes ore pulp charge door 5 and hydrochloric acid charge door 6, wherein, it is anti-that ore pulp charge door 5 is arranged on the first order
The top of groove is answered, hydrochloric acid charge door 6 is arranged on the middle and lower part of first order reactive tank.Material can be made after entering reactive tank in stirring
It is sufficiently mixed rapidly with lower, overflows to each area successively, ensure the enough reaction time.
The agitating paddle 4 is Double-layer stirring paddle.Lower floor's agitating paddle main function is mixed material, and upper strata agitating paddle main function is
Defoaming, can make reactant stir, be advantageous to react by Double-layer stirring paddle.
The reactive tank 1 is provided with steam heater and temperature regulating device.It is can be achieved by the two to each section of reactive tank
Reaction temperature carry out strict control and regulation, ensure that reaction temperature is optimal.
The reactive tank 1 is made up of the carbon brick line with rubber layer of internal layer and the rust steel layer of outer layer.Due to material chloride ion content compared with
Height, by setting carbon brick line with rubber layer and rust steel layer, effectively reactive tank can be prevented to be corroded, extend the service life of reactive tank.
