Abstract
The invention relates to a bottom valve of a crystallizing tank. A flashboard of the bottom valve is used for plugging the feeding opening of the crystallizing tank and the surface of the flashboard is changed from a flat surface to be gradually oblique towards the periphery with a bulging in the center, like a cone or hemisphere. Therefore, the surface of the flashboard does not hold crystal when the bottom valve is opened to feed after crystallization, the operation is simple and the quality of the crystallized products is improved.
Description
Technical field
The present invention relates to a kind of bottom valve of crystallizing tank.
Background technology
For guaranteeing product quality, before doing crystalline product, people can carry out preliminary treatment to crystal solution, remove the impurity in the crystal solution as far as possible.In fact, preprocessing process is difficult to impurity is eliminated.Toward contact is remaining small amount of impurities arranged in the crystal solution.And crystallization process itself also is one further to purify, the process of refined product purity.
In the product crystallization process, there is the impurity that partly remains in the crystal solution to be mixed in the crystallization unavoidably and separates out together.But the impurity that these are separated out is not even distribution, often concentrates in a small amount of " crystalline solid ".In most cases, assembling " crystalline solid " of impurity, proportion is bigger, is deposited on the crystallizing tank bottom.And the crystallization on upper strata in the crystallizing tank, the purity height, quality is good.This phenomenon called after " the assembly effect of crystallization ".
Present problem is, on the bottom valve of crystallizing tank.Flashboard format surface in order to feed opening at the bottom of blocking jar is the plane.Because the feed opening diameter of crystallizing tank is bigger.As enamel pot commonly used, volume is 500 liters, and 1000 liters enamel pot, feed opening diameter are 80mm; Volume is 2000 liters, and 3000 liters enamel pot, feed opening diameter are 100mm; Volume is 5000 liters a enamel pot, and the feed opening diameter is 125mm.Certainly, the flashboard diameter of bottom valve correspondingly.So big one flat plate is blocked feed opening, slowly opens bottom valve during blowing earlier, and a small amount of particle of assembling impurity of bottom settlings is emitted in attempt,, be trapped on the flat board those and assembling the bad separation of material of impurity, have to bring in the product, and reduce the purity of product by it.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of bottom valve of crystallizing tank is provided, and the crystallizing tank with this bottom valve can effectively separate impurity with product, improves product purity.
For solving above technical problem, the present invention takes following technical scheme:
A kind of bottom valve of crystallizing tank, it has the flashboard of the feed opening that is used for the shutoff crystallizing tank, the shape that particularly, the surface of described flashboard is center projections, progressively tilt to circumference.
Described flashboard can be taper shape or hemispherical.
Because the enforcement of above technical scheme, the present invention compared with prior art has following advantage:
The present invention utilizes the assembly effect of crystallization, flashboard is designed to center projections, and progressively the shape that tilts to circumference is like this, arrived the crystallization terminal point, when opening the bottom valve blowing, at first slowly open flashboard, " crystalline solid " particle of assembling impurity of bottom settlings will be owing to the effect of gravity, slide along curved surfaces, wait until recrystallization or do other processing, thereby effectively impurity is separated, refilter the measured crystalline product of purity height, matter that separates the upper strata.By the ingenious design of flashboard, solved separating of impurity and product in the crystalline product.
Description of drawings
The present invention will be further described in detail below in conjunction with accompanying drawing and concrete embodiment.
Fig. 1 is the structural representation of the flashboard of embodiment 1;
Fig. 2 is the structural representation of the flashboard of embodiment 2;
Wherein: 1, flashboard.
The specific embodiment
Embodiment 1:
As shown in Figure 1, have the flashboard 1 of the feed opening that is used for the shutoff crystallizing tank according to the bottom valve of the crystallizing tank of present embodiment, the surface of this flashboard 1 is a hemispherical.
Embodiment 2:
As shown in Figure 2, have the flashboard 1 of the feed opening that is used for the shutoff crystallizing tank according to the bottom valve of the crystallizing tank of present embodiment, the surface of this flashboard 1 is conical.
Because among the present invention, the surface of flashboard 1 changes center projections into by the plane, the shape that tilts to circumference progressively, as cone, or hemisphere, just can not hold back material.Material will be owing to the effect of gravity, slides along smooth cone surface (or hemisphere face), so, just can will assemble the particle separation of impurity more up hill and dale, thereby removing impurities obtains the crystalline product of high-quality.
Claims (1)
1. crystallizing tank, its bottom valve has the flashboard (1) of the feed opening that is used for the shutoff crystallizing tank, it is characterized in that: described flashboard (1) is a hemispherical.
