Abstract

The utility model discloses a residual starch recovery plant in a process of skimming liquid by using a scraper. A starch milk slurry tank is additionally arranged below a sedimentation tank; the bottom of the sedimentation tank is connected with the starch milk slurry tank through a pipeline; a starch milk backflow pipeline mounted at the upper edge of the bottom of the sedimentation tank is connected with a hose; a starch milk slurry tank channel is arranged on the hose; a lateral wall washing pipeline is mounted on the tank bottom of the sedimentation tank along a lateral wall; a tank bottom washing pipeline is mounted at the bottom of the sedimentation tank; a feeding pipeline is mounted at the bottom of the starch milk slurry tank; a three-way valve is mounted at the back section of the feeding pipeline; and the remained valve ports of the three-way valve are connected with a gathering pipeline of the lateral wall washing pipeline and the tank bottom washing pipeline. The residual starch recovery plant provided by the utility model has the beneficial effects as follows: the concentration of starch slurry in the sedimentation tank is obviously reduced, so that the mobility is obviously increased; the time of recovering residual strum is greatly shortened due to the arrangement of the starch milk slurry tank; and the working efficiency of the sedimentation tank is improved.

Description

Scraper is cast aside remaining recovery of starch device in the liquid

Technical field

The utility model relates to a kind of scraper and casts aside remaining recovery of starch device in the liquid.Described scraper is cast aside liquid and is meant the production waste liquid that generates when in the starch based products production, using scraper to carry out the processed of milk of starch.

Background technology

In starch and modified starch production, most of producer all carries out the processed of milk of starch at the use scraper at present, and remaining starch sedimentation in slurry tank that scraper is cast aside in the liquid is collected.Because it is that the starch emulsion on top layer forms during by the scraper spinning that scraper is cast aside liquid; Starch granules degree wherein is very little, and crushed particles is many, after in slurry tank, stopping for a long time; Supernatant is discharged by riser, forms dense starch slurry but starch granules is settled down to pot bottom.This underflow mobile very poor causes the discharging time long, influenced scraper and cast aside the collection effciency of liquid starch, and then restricted the production efficiency of whole production line.If address this problem, can further reduce the manufacturing cost of starch and modified starch.

Summary of the invention

The goal of the invention of the utility model is to provide a kind of scraper to cast aside remaining recovery of starch device in the liquid.Adopt this device can shorten the recovery time of starch, improve the slurry tank working efficiency.

The technical scheme of the utility model is: this device comprises and has conical jar of end slurry tank, below slurry tank, sets up a milk of starch underflow jar, and the butterfly valve of slurry tank bottom is connected with milk of starch underflow jar through the blowing pipeline; On the upper edge outer wall at the bottom of the slurry tank jar, the milk of starch reflux pipeline is housed, on the milk of starch reflux pipeline ball valve is housed, milk of starch reflux pipeline bottom is with hose connection; Flexible pipe is provided with two passes, and one is to lead to trench, and another gets into milk of starch underflow jar; On jar upper edge, the end sidewall of slurry tank, the sidewall flushing line is housed, flushing line at the bottom of being equipped with jar in the bottom of slurry tank is equipped with ball valve respectively on two flushing lines, and flushing pipeline at the bottom of the tail end of sidewall flushing line is incorporated into jar constitutes and converges pipeline; Feed-stock pipeline is equipped with in the bottom of milk of starch underflow jar; Ball valve, starch pump and falling film type tensimeter are housed on feed-stock pipeline; The back segment of feed-stock pipeline is equipped with a T-valve, and the residue valve port of T-valve is connected with jar pipeline that converges of end flushing line with the sidewall flushing line.

The beneficial effect of the utility model is owing to set up milk of starch underflow jar and many flushings, reflux pipeline; Reduced the concentration of starch slurry in the slurry tank significantly; Its flowability is enlarged markedly; The recovery time of remaining starch has been shortened in the setting of milk of starch underflow jar greatly, has improved the slurry tank working efficiency.

Embodiment

Example 1

As shown in Figure 1, this device comprises the slurry tank 1 that has the conical jar end, and feed-pipe 2 probes into tank body from the top of slurry tank 1, on slurry tank 1 top sidewall, is provided with upflow tube 3.

Below slurry tank 1, have additional a milk of starch underflow jar 4, the butterfly valve 5 of slurry tank 1 bottom is connected with milk of starch underflow jar 4 through blowing pipeline 6.On the upper edge outer wall at the bottom of the slurry tank jar, milk of starch reflux pipeline 7 is housed, ball valve 8 is housed on the milk of starch reflux pipeline 7, milk of starch reflux pipeline 7 bottoms are connected with flexible pipe 9.Flexible pipe 9 is provided with two passes, and one is to lead to trench, and another gets into milk of starch underflow jar 4.

On the sidewall of the jar upper edge, the end of slurry tank 1, sidewall flushing line 10 is housed; Flushing line 11 at the bottom of being equipped with jar in the bottom of slurry tank 1; Article two, on the flushing line ball valve 8 is housed respectively, flushing pipeline 11 at the bottom of the tail end of sidewall flushing line 10 is incorporated into jar constitutes and converges pipeline 16.

Feed-stock pipeline 12 is equipped with in the bottom of milk of starch underflow jar 4; The back segment that ball valve 8, starch pump 13 and falling film type tensimeter 14 feed-stock pipelines 12 are housed on feed-stock pipeline 12 is equipped with a T-valve 15, and the residue valve port of T-valve 15 is connected with jar pipeline 16 that converges of end flushing line 11 with sidewall flushing line 10.

Example 2

The design's actually operating method: the butterfly valve 5 of closing bottom at the bottom of 1 jar of the slurry tank; Scraper is cast aside liquid and is pumped into slurry tank 1 by feed-pipe 2; Wait to cast aside liquid pump intact after, starch sedimentation 2 hours is put into trench with flexible pipe 9; Open ball valve 8 clear liquid is disposed to trench fully, then flexible pipe 9 is inserted milk of starch underflow jar 4.
