Description
Technical field
The present invention relates to a kind of reaction kettles, particularly relate to a kind of staggered form circulation stirring chemical reaction kettle.
Background technique
Reaction kettle is comprehensive reaction vessel, the design according to reaction condition to reaction kettle structure function and configuration attachment.From
Charging-reaction-discharging of beginning can complete pre-set reaction step with higher the degree of automation, to anti-
The important parameters such as temperature, pressure, mechanics control (stirring, air blast etc.), reactant/product concentration during answering carry out stringent
Regulation.
Reaction kettle is a kind of chemical plant commonly consersion unit, and it is anti-to stir mainly to drive agitating shaft by motor
Object is answered to react it sufficiently to obtain required substance.With the continuous hair of chemical field, life of the people to chemical products
The precision of finished product and chemical products all improves higher requirement, and corresponding people are to the important equipment reaction kettle in chemical reaction
Higher requirements are also raised.Currently used reaction kettle realizes that long-time constant temperature is kept the temperature by way of heating, for existing
After reaction kettle has reacted, reaction kettle also has a biggish temperature, present processing mode be essentially all directly be allowed to cool and
It is not used, causes the waste of the energy.
Reaction kettle is the reflection container of the mixed function of heating, evaporation, cooling and the low high speed of realizing that technique requires,
In, the mixing of solid-liquid material frequently encounters in chemical industry with the problem of reacting, since solid particle is bigger, it is difficult to it mixes,
It affects the efficiency that solid is mixed with liquid and causes mixing uneven.
In the prior art, the aperture segment in large container is in side wall, and during use, a large amount of residuals are arranged at bottom
Liquid, because of the problem in design, bottom is difficult to clear up.Its is inconvenient for use, cleaning is inconvenient, and cost of labor is caused to rise.Its

This, liquid can enter from the side of reaction tank 1, be sufficiently stirred effect through the first paddle 4 and the second paddle 5, then from another
The outlet end 6 of side flows out.Also, it, can be by the liquid for being not easy to stir of bottom deposit due to the effect of the water circulating pump of bottom 8
Body drives, to realize the staggered form circulation of entire reaction tank 1.
Above description, to be followed based on above-mentioned staggered form according to staggered form circulation stirring chemical reaction kettle of the present invention
Ring stirs chemical reaction kettle, workflow are as follows:
Step 1: liquid is entered from the outlet end 6 of 1 top side of reaction tank in spherical filter 2；
Step 2: after the liquid of 2 pairs of filter entrance is filtered, liquid enters opening for 1 top of reaction tank through 2 bottom of filter
In mouthful；
Step 3: being in the first paddle 4 and the second paddle 5 of V shape structure by two into the liquid of reaction tank 1
It is sufficiently stirred；
Step 4: two water outlets 9 through 8 two sides of water circulating pump are discharged after bottom liquid is sucked by water circulating pump 8, again with the
Liquid after one paddle 4 and the stirring of the second paddle 5 realizes cross-circulation；
Step 5: the outlet end 6 of the reacted 1 bottom other side of pond of liquid after above-mentioned steps are sufficiently mixed is discharged, and completes to stir
Mix reaction process.
Staggered form circulation stirring chemical reaction kettle according to the present invention has the following characteristics that
(1) it uses top to enter liquid mode, and liquid can be broken up after filtering, tentatively mixed；
It is in V shape structure between (2) first paddles 4 and the second paddle 5, can be realized sufficient stirring action；
(3) water circulating pump 2 of bottom setting can stir bottom liquid, follow again with the first paddle 4 and the realization of the second paddle 5
Ring；
(4) water circulating pump 8 is two export structures, and recirculated water can be discharged in two directions, uniformly follow so as to realize
Ring effect.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention, it is all
