Abstract

The invention discloses a starch emulsion defoaming pump which comprises a pump body. The pump body is provided with a first cavity and a second cavity which are respectively and internally provided with a primary impeller and a secondary impeller, the primary impeller is provided with an outer shell and a hub, six radial big blades are evenly arranged between the outer surface of the hub and the inner wall of the outer shell, the rotary central line of the big blades and the central line of the hub form a horizontal eccentric distance of 12.8mm and a vertical the eccentric distance of 1.8mm, the middle of each big blade is respectively provided with a small blade which forms an included angle of 125 degrees with the big blade, and the right end part of the outer shell is evenly provided with twelve subsidiary blades along the axial direction. The primary impeller is provided with the six big blades at inclined angles, a small blade is attached to each big blade, and the twelve subsidiary blades are arranged at the tail end of each big blade. When the starch emulsion defoaming pump is in use, deforming is firstly carried out by the big blades and the small blades attached to the big blades and then carried out by the subsidiary blades, therefore, the wheel defoaming rate reaches over 80 percent.

Description

technical field [0001] The invention relates to a pump, in particular to a starch emulsion defoaming pump. Background technique [0002] Generally, the extraction process of potato starch is as follows: first, it is cleaned and stone-extracted, and then it is thoroughly crushed by a high-efficiency rasp mill to become a potato emulsion, and then the potato emulsion is sent to the extraction unit consisting of a centrifugal sieve and a hydrocyclone. In the above production process, the potato starch emulsion after passing through the centrifugal sieve produces a large amount of foam in the flow, which seriously affects the separation effect of the hydrocyclone. Add foam breaking and defoaming processes between the "centrifugal sieve", that is, the starch emulsion containing a large amount of foam after preliminary separation through the "centrifugal sieve", first of all it must be broken (the small bubbles in the huge foam mass are broken to make the foam Concentration) and ...
