Abstract

The utility model relates to a bag type distillers' grains solid and liquid separator, which is composed of the parallel combination of a plurality of cloth filter bags. The filter bags are made by tailor-made filtering mediums. The bag type distillers' grains solid and liquid separator can guarantee steady flow constant pressure filtering, and easily forms a filtering layer. Grains which are smaller than filtering medium holes are trapped, so filtering liquid is clear. The suspended matter content is below 500 mg/L, and the water content of lees mud is below 80%. The utility model has the advantages of reliable continuous filtration, high capability, less investment, small occupation area, low energy consumption, less treating cost price, simple operation, convenient machine loading, low freight and no pollution. The utility model can replace large-sized stillage filters and enrichment facilities, does not need factory buildings, and relieves the labor intensity of loading.

Description

Bag type distillers' grains solid and liquid separator

The utility model belongs to the solid-liquid separation technique field.

A large amount of vinasse waste liquids is discharged in alcohol and liquor production, contains a large amount of suspension-vinasse in the waste liquid.Dewatering whole stillage does not still have good method so far, and vinasse filter with large-scale filtering ponds in most breweries, and its shortcoming is floor space big (generally taking up an area of tens mu).Vinasse entrucking labour intensity is big, and it is too many to take a lot of work, the freight charges height.The distiller's grains liquor suspension content does not still reach pollution emission standard.Poor slurry pollutes the road surface in the transportation, influences health.Also have only a few producer to separate vinasse waste liquid suspension with centrifuge, clearance is below 80%, and poor mud water content does not still reach discharge standard more than 80%.And equipment investment is big, the rotary drum serious wear, and treatment cost height, noise be more than 95 decibels, the consuming electric power height.

This is suitable for novel purpose and provides a kind of pocket type vinasse solid-liquid separator, the Separation of Solid and Liquid of the liquid that can be pickled with grains or in wine reliably continuously.The content that separates back clear liquid suspension is lower than discharge standard 500PPM(500mg/L).Poor mud water content is lower than 80%.This equipment can be worked continuously automatically, and separating power is big, and the energy resource consumption of equipment own is low.Can replace equipment such as large-scale filtering ponds and concentration tank.This equipment is operated, management is all simple and convenient, and occupation of land face is few, does not also need factory building.The vinasse that are suitable for especially not needing to dry are administered.Alleviate the filtration burden for simultaneously the poor mud of press filtration water.Divide the condition of having created for further draining poor muddy water.

The principle of pocket type vinasse solid-liquid separator: the filter medium of bag group is special filter screen.Utilize vinasse granule size difference too big, can form the natural filtration layer, under the condition that voltage stabilizing is filtered, liquid does not produce impact, and the vinasse particle littler than mesh still is trapped.So can reach the high and low purpose of poor mud moisture content of the suspended substance removal rate of vinasse waste liquid, see accompanying drawing.

The design feature of pocket type vinasse solid-liquid separator: (1) filter bag group 5 is made up of numerous filter bags, and each filter bag all is upright, and has same velocity of rotation.Rotating speed soon, can require the levelling transmission device according to dehydration slowly.All having a spiral shell auger 13 constantly to rotate in each filter bag shifts the poor mud in the filter bag in the poor mud pipe 7 of storage onto.Revolve auger 12 by the mud snail that goes out to be pickled with grains or in wine and release poor mud, can handle or add merit deeply.

(2) the poor liquid of being sent here by feed pipe 1 is introduced into poor liquid distributing pipe 2, and poor liquid is assigned in each filter bag in bag filter group 5.Bag inner filtration pressure big and little can cut down 6 according to the levelling of the reading on the Pressure gauge 4 overflow, and unnecessary feed liquid is returned the original place by overflow pipe 3.Guaranteed the voltage stabilizing filtration.

What of the poor mud water content of (3) coming out can be cut down 9 by the mud that goes out to be pickled with grains or in wine and align.Support 8, baffle plate 11.

The clear liquid that each filter bag is separated is flowed out by purified liquor outlet pipe 10.Other processes, and the part clear liquid can reuse.The secondary stock that this equipment also can be used for papermaking reclaims.

Claims

1, a kind of pocket type vinasse solid-liquid separator, it is characterized in that (1) this equipment is formed by garden tubular filter bag group 5 vertical installations, (2) each garden tube filter bag in the bag filter group 5, all there is one screw auger 13 vertically is installed, constantly rotate, dense poor mud in the bag is shifted onto in the poor mud pipe 7, and released by the mud auger 12 that goes out to be pickled with grains or in wine.

2, solid-liquid separator according to claim 1 is characterized in that: cut down 6 by Pressure gauge 4 and overflow pressure regulation, align the filter pressure in the filter bag, reach the requirement that voltage stabilizing is filtered.

3, solid-liquid separator according to claim 1 is characterized in that: control out the content that poor muddy water divides by aligning the size that poor mud cuts down 9 openings.
