Sugar industry emulsifying lime slurry centrifugal pump

Abstract

The invention relates to an emulsified hydrated lime centrifugal pump in the sugar industry, wherein the front section of a rotary shaft is positioned inside a pump body; the pump body is provided with a slurry inlet end and a slurry outlet end; the cavity of the pump body is provided inside with a primary stator and a primary rotor which are matched with each other; the primary rotor is of centrifugal type and is matched with the primary stator to form a particle shearing cutting edge; when hydrated lime is fed into the pump body, the centrifugal primary rotor rotates at a high speed and has the function of slurry pumping; meanwhile, the particles inside the hydrated lime are effectively divided by the particle shearing cutting edge; therefore, the hydrated lime is fully shorn and emulsified and then is pumped out from the slurry outlet end so as to be conveyed to a syrup pool. The emulsified hydrated lime centrifugal pump eliminates the phenomenon of serious post reaction in the prior art, thereby substantially improving the quality and the purity of sugar product.

Description

technical field [0001] The invention relates to a pump used in the sugar industry, in particular to a pump used for shearing and emulsifying lime slurry and delivering the slurry. Background technique [0002] In the general process of sugar production, lime disintegrators are used to crush lime into lime slurry, which is then transported by centrifugal pumps, mortars and other equipment. The biggest problem in this process is that the size of the processed lime slurry particles is usually within 1 ~2mm, the reaction between the lime slurry containing a large number of particles and the syrup is incomplete, and the post-reaction is more serious, so that the pH value of the syrup cannot be kept within the normal and stable range, resulting in unstable quality and purity of the product sugar. In the above-mentioned traditional process, the centrifugal pump, mortar and other equipment used only have the function of conveying and have no emulsifying and shearing function. Of cou...

Problems solved by technology

[0002] In the general process of sugar production, lime disintegrators are used to crush lime into lime slurry, which is then transported by centrifugal pumps, mortars and other equipment. The biggest problem in this process is that the size of the processed lime slurry particles is usually within 1 ~2mm, the reaction between the lime slurry containing a large number of particles and the syrup is not complete, that is, the post-reaction is more serious, so that the pH value of the syrup cannot be kept within the normal and stable range, resulting in unstable quality and purity of the product sugar

In the above-mentioned traditional process, the centrifugal pump, mortar and other equipment used only have the function of conveying and have no emulsifying and shearing function. Of course, it is impossible to eliminate a large number of particles in the lime slurry entering the syrup liquid, which constitutes a serious obstacle to the stability and improvement of product quality.
