Horizontal starch centrifugal sieve device

Abstract

The invention discloses a horizontal starch centrifugal screen device which comprises an enclosure, a feeding pipe and a backflush water pipe, wherein a conical screen basket is arranged in the enclosure; the enclosure is divided into a material feeding cavity and a material discharging cavity by the conical screen basket; a discharge opening of the feeding pipe extends to a part close to a cone bottom; the backflush water pipe is communicated with a backflush spray pipe; an online screen mesh cleaning device is arranged in the feeding cavity; the cleaning device consists of conical sandwich water tanks arranged in the conical screen basket at intervals and positive flushing water pipes arranged on the inner sides of the conical sandwich water tanks; the conical sandwich water tanks and the positive flushing water pipes are respectively sealed and extend out of the enclosure; spray nozzles are uniformly distributed on the surface, facing a screen mesh, of each conical sandwich water tank; a plurality of spray heads are uniformly distributed on the positive flushing water pipe; the spray heads are respectively sealed and penetrate through the conical sandwich water tanks; spray mouths of the spray heads are respectively and obliquely arranged towards the conical mouth direction of the conical screen basket. The horizontal starch centrifugal screen device disclosed by the invention has the advantages that online cleaning of the screen mesh of the horizontal starch centrifugal screen device is realized; the screen mesh is cleaned without stop, so that the aims of improving the working efficiency and reducing the production cost are achieved.

Description

technical field [0001] The invention relates to a starch centrifugal sieve, in particular to a horizontal starch centrifugal sieve device. Background technique [0002] In the starch production process, the starch centrifugal sieve is mainly used in the starch screening section to separate impurities in the starch slurry. Due to the influence of factors such as starch viscosity, particle size and impurities, it is easy to cause blockage of the screen, and the separation efficiency gradually decreases with the prolongation of production time. Although the currently used horizontal starch centrifugal sieve device itself is equipped with a back-flushing water pipe cleaning device, it can only delay the clogging of the screen to a certain extent and cannot fundamentally solve the problem of screen clogging, resulting in starch screening every A period of time will stop cleaning, greatly reducing production efficiency and increasing production costs.

Problems solved by technology

Due to the influence of factors such as starch viscosity, particle size and impurities, it is easy to cause blockage of the screen, and the separation efficiency gradually decreases with the prolongation of production time.

Although the currently used horizontal starch centrifugal sieve device itself is equipped with a back-flushing water pipe cleaning device, it can only delay the clogging of the screen to a certain extent and cannot fundamentally solve the problem of screen clogging, resulting in starch screening every After a period of time, it will be shut down for cleaning, which greatly reduces the production efficiency and increases the production cost
