Abstract

The utility model relates to a bent boult in the corn flour production equipment, in particular to a bent boult filter aid, which comprises a shell and a filter. The shell appears tube structure, wherein the filter is arranged longitudinally. The filter is connected to the feed duct through the flange on two sides. The filter and the liquid cavity formed by the shell are communicated through the water duct and the upper controlling valve and the lower liquid cavity of the bent boult. The bent boult filter aid is installed in the bent boult duct, which makes the pre-separation of feed liquid through the filter. Then, according to the need, the moisture capacity adjustment of feed liquid is accomplished through the control valve, which resolves the problem of the difficult control of the proportion of the feed and liquid in the production of corn flour production. Moreover, the filter aid has the advantage of convenient operation, easy control of craftwork target and has no need to increase the motivity.

Description

Curve shieve filter aid

Technical field:

The utility model relates to the song sieve in the cornstarch production equipment, particularly a kind of curve shieve filter aid.

Background technology:

In the cornstarch process, generally adopt bent sieve that the material in water material or the slurry, liquid are separated, as: drive corn with water and utilize the power of pump that water and corn are delivered on the compass screen surface of gravity curved screen, corn is slipped to from compass screen surface and soaks batch can or the balanced storehouse, water then stitches the feeder channel that leaches before suitable return duct flows back to pump from sieve, circulates again with water band material again.In the corn course of conveying, amount of water is very few to cause line clogging easily, and amount of water is excessive then can be made the corn belt dilutional hyponatremia on the gravity curved screen compass screen surface and influence production efficiency.Also have, in the countercurrent washing process of fiber, because starch contained in the fiber is fewer and feweri, dry is fewer and feweri on the compass screen surface of the bent sieve of build-up of pressure, compass screen surface slide water phenomenon often appears, especially the pressure curved sieve extracted on the machine of fiber is even more serious, extracts work to fiber and brings operational difficulty, makes the excessive waste that causes the energy of fiber moisture content after extracting.Have again, at the broken corn that takes off embryo when the pressure curved sieve since in the material with slurries too much, often occur that pin mill current of electric is too high, the moving pin of pin mill grinds inclined to one side phenomenon, simultaneously since in the fiber content of starch too high also work brings very big difficulty to fiber wash.

Summary of the invention:

Goal of the invention of the present utility model be intended to solve above-mentioned for material in the bent sieve institute feed liquid, liquid proportional can not fine control problem, and provide a kind of material proportion of controlling, can finish filtration work preferably, improve the curve shieve filter aid of every technic index.

The technical scheme that realizes the foregoing invention purpose is: this curve shieve filter aid comprises housing, chimney filter, this housing is tube structure, chimney filter vertically is set in it, this chimney filter is connected in the feeding pipeline by the flange at its two ends, the sap cavity that chimney filter and housing form by aqueduct and on control valve and bent sieve sieve sap cavity UNICOM down.

According to this curve shieve filter aid that this case provides, it is installed in the bent sieve feeding pipeline, by chimney filter feed liquid is separated in advance, then as required, carries out the water content of feed liquid by its control valve and regulates.When water content is too much, open control valve, then the isolated in advance moisture of chimney filter is directly transported to bent sieve water return pipeline, make material in the material that reaches on the bent sieve compass screen surface, liquid proportional controlled; When not needing to reduce the feed liquid water content, get final product closed control valve.Bent sieve is set up this filter aid, has thoroughly solved the problem that material that present cornstarch exists in producing, liquid proportional can not fine controls, and this filter aid have easy to operate, be easy to control technic index, need not increase advantage such as power.

Description of drawings:

Fig. 1 is the structural representation of the utility model when using on gravity curved screen.

Fig. 2 is the structural representation of the utility model when using on pressure curved sieve.

The specific embodiment:

Provide specific embodiment of the utility model below in conjunction with accompanying drawing.

Embodiment 1 is mounted in the curve shieve filter aid that uses on the gravity curved screen, it is made up of housing 1, chimney filter 2, flange 3, aqueduct 4, control valve 5, this housing 1 is tube structure, chimney filter 2 vertically is set in it, this chimney filter 2 is connected in the feeding pipeline 6 by the flange 3 at its two ends, the sap cavity that chimney filter 2 and housing 1 form by aqueduct 4 and on control valve 5 and bent sieve sieve sap cavity 8 UNICOMs down.During work, feed liquid enters bent sieve again by chimney filter 2 earlier, flow to compass screen surface 9 equably by overfall dam 11 then, the liquid in the feed liquid through compass screen surface infiltrate sieve down sap cavity 8 and by the water return pipeline 7 backspace pumps of lower end, chamber before the dnockout groove, the solid material in the feed liquid is then by falling into oversize material feed opening 10.When needs reduce water content in the feed liquid, then open control valve 5, make the isolated in advance moisture of chimney filter 2 directly transport to bent sieve water return pipeline 7, material, liquid proportional are effectively controlled in the feed liquid on the bent sieve compass screen surface 9 and reach.

Embodiment 2 is mounted in the curve shieve filter aid that uses on the pressure curved sieve, and it also is made up of housing 1, chimney filter 2, flange 3, aqueduct 4, control valve 5 equally, and each member connection structure and embodiment 1 are together.Pressure curved sieve is by the feed nozzle 12 of feeding pipeline 6 ends material spray on the song sieve compass screen surface 9, liquid in the feed liquid under pressure through compass screen surface enter sieve down sap cavity 8 and by the water return pipeline 7 backspace pumps of lower end, chamber before the dnockout groove, the solid material in the feed liquid is then by falling into oversize material feed opening 10.The method of material, liquid proportional and embodiment 1 are together in the adjusting feed liquid.

Claims

1, a kind of curve shieve filter aid, comprise housing, chimney filter, it is characterized in that this housing is tube structure, chimney filter vertically is set in it, this chimney filter is connected in the feeding pipeline by the flange at its two ends, the sap cavity that chimney filter and housing form by aqueduct and on control valve and bent sieve sieve sap cavity UNICOM down.
