Cyclone separator for starch washing

Abstract

The invention provides a cyclone separator for starch washing. The cyclone separator for starch washing comprises a cyclone separator cylinder, raw material inlets and a distribution plate, wherein the upper parts of the front end surface and the rear end surface of the cyclone separator cylinder are each fixedly connected with a group of raw material inlets; a group of overflow ports is fixedly connected to the top part of the cyclone separator cylinder; a group of heavy medium underflow ports is fixedly connected to the bottom part of the cyclone separator cylinder; and a group of reflux inlets is connected to the right sides of the heavy medium underflow ports. The distribution plate is arranged in the cyclone separator cylinder so as to distinguish bottom media, heavy media enter the next stage, and light media or non-obviously separated media are re-input into the raw material inlets through the reflux inlets so as to be washed, so that the purity of outlet parts of the heavy medium underflow ports is improved, a washing effect and a separating effect of a single cyclone separator are improved, the number of the cyclone separators in a washing and separating system group is reduced, the washing and separating process is simplified, and the space occupied by the equipment is reduced.

Description

technical field [0001] The invention belongs to the technical field of separation equipment, and more specifically relates to a cyclone separator for starch washing. Background technique [0002] In the starch production process, it is necessary to wash the starch to remove impurities such as gluten and potato dregs in the starch. Cyclone separators are often used in the washing of starch. Cyclone separators generally use the starch granules in the material to circulate in the swirling flow. The centrifugal sedimentation in the tube and the floating effect of the liquid (or fiber) realize the separation of materials. [0003] Based on the above, combined with the discovery of equipment in the prior art, the washing effect of a single cyclone separator in the existing cyclone separator is limited and cannot meet the production needs. In order to improve the washing effect in production, it is usually necessary to combine multiple sets of cyclone separators Connections are us...

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides a cyclone separator for starch washing, to solve the problem that the existing cyclone separator has a limited washing effect of a single cyclone separator and cannot meet the production needs. In order to improve the washing effect in production, it is usually It is necessary to connect and combine multiple sets of cyclone separators. Usually, there are 12-stage, 18-stage and other multi-stage connection methods. The entire washing and separation group system is huge, taking up a large space in production, and the production process is complicated.
