Abstract

The utility model discloses an L-lactic acid flocculated clarified liquor filter, which comprises an outer shell and a filter element, which are fastened and connected into a whole through bolts and nuts. The clarified liquor obtained after flocculation and sedimentation of the L-lactic acid fermentation liquor contains a few fine biomass particles, after entering the outer shell from a liquor inlet valve of the filter, the fine biomass particles are separated inside the shell by filter screens outside the filter element and gradually sink into a lower cone; clear filtrate enters the filter element and is discharged into the next procedure of concentration through a clear filtrate outlet valve; after a period of running, the filter screens are blocked by the biomass particles and need washing and cleaning, at the moment, a clarified fermentation liquor inlet valve and the clear filtrate outlet valve are closed and a bottom blow-off valve and a clear water inlet valve are opened to wash the filter screens with high pressure clear water along the reverse direction from the interior of the filter element, so that biomass particles can be discharged from the blow-off valve along with water. By adopting a backwash method with high pressure clear water, the filter does not need to be dismounted, is convenient to operate and has the advantages of high washing speed and good effect.

Description

L-lactic acid flocculate and clarify liquid filter
Technical field;
The utility model relates to L-lactic acid and extracts refining plant, directly relates to a kind of L-lactic acid flocculate and clarify liquid filter.
Background technology
China from last century end the biofermentation that begins one's study produce L-lactic acid, realized suitability for industrialized production at present.To fermentation technique with extract purification techniques and still furtheing investigate, strive seeking fermentation conversion rate height, extract yield is high, the purified product quality is high process production techniques and device.Wherein the L-lactic fermentation liquid is behind flocculating setting; Clarified solution is discharged from the subsider overflow; Get into the L-lactic acid clarified solution feed tube of the utility model then; Wherein still contain part biological amount fine particles and influence concentrated making with extra care of step down, need to adopt L-lactic acid flocculate and clarify liquid filter further to remove this part biomass particulate.And filter screen is prone to stop up in the existing L-lactic acid flocculate and clarify liquid filter running, needs regularly to shut down to change.
Summary of the invention:
The purpose of the utility model just provides a kind of new L-lactic acid flocculate and clarify liquid filter, and it can effectively solve, and filter screen is prone to stop up in the existing L-lactic acid flocculate and clarify liquid filter running, need regularly to shut down the problem of changing.
The purpose of the utility model is achieved in that L-lactic acid flocculate and clarify liquid filter, has shell body, filter core, and the main part of shell body is the cylinder that is welded into by the stainless steel coiled sheet, the upper end welded flange; Lower end welding cone, the side perforate welding L-lactic acid flocculate and clarify liquid feed tube on cylinder top, and the feed liquor valve is installed; The welding blow-off pipe in the cone lower end, and blowoff valve is installed, filter core is the cylinder that is welded into the stainless steel coiled sheet that is uniformly distributed with boring; The steel plate welded seal is used in the bottom, and welded flange lid in upper end is with the two-layer cylinder periphery that is wrapped on of 200 mesh filter screens; The perforate welding L-lactic acid cleaner liquid outlet in the blind flange centre, and liquid valve is installed, shell body and filter core are fastenedly connected with bolt and nut; The intermediate cryptographic packing, perforate welding backflushing water intake pipe on blind flange, and be installed into water valve.
Adopt the L-lactic acid flocculate and clarify liquid filter of the utility model, can realize the high pressure clear water from the inner back flush filter core of filter core, easy to operate, cleaning speed is fast, need not regularly to shut down to change filter screen.
Description of drawings:
Accompanying drawing illustrates the structural representation of the utility model, below in conjunction with accompanying drawing the utility model is described further.
The specific embodiment:
Accompanying drawing is the structural representation of the utility model L-lactic acid flocculate and clarify liquid filter, has shell body 1 and filter core 2, connects to form one with bolt and nut 17.
The main part of said shell body 1 is the cylinder 3 that uses thickness to be welded into as the stainless steel coiled sheet of 8mm, and 0.8 meter of diameter is high 1.5 meters.The cone 4 that the lower end welding is welded into the thick stainless steel coiled sheet of 8mm, 45 ℃ of taperings are high 0.5 meter.Cylinder 3 upper ends weldering flange 9, perforate welding L-lactic acid flocculate and clarify liquid feed tube 5 is φ 108 * 3mm stainless steel tube apart from 0.2 meter, flange 9 bottoms; Feed liquor valve 6 is installed in the outer end; Welding blow-off pipe 7 is φ 76 * 3mm stainless steel tube in cone 4 lower ends, and blowoff valve 8 is installed in the lower end.
Said filter core 2 is to be uniformly distributed with the cylinder 10 that the stainless steel coiled sheet of boring is welded into thickness 6mm, and 0.5 meter of diameter is high 1 meter; Periphery is with on 200 order stainless steel filtering nets, 11 two-layer parcels and the stationary cylinder 10, and the lower end seals with corrosion resistant plate, upper end welded flange lid 12; At blind flange 12 centre perforate welding L-lactic acid cleaner liquid outlets 15; Be φ 108 * 3mm stainless steel tube, and cleaner liquid liquid valve 16 is installed, perforate welding backflushing water intake pipe 13 at 0.3 meter of blind flange 12 partial centers; Be φ 57 * 3mm stainless steel tube, and be installed into water valve 14.
After the flange 9 of said shell body 1 and filter core 2 overlapped with blind flange 12, fastening with bolt and nut 17, the centre folded up asbestos board sealing gasket 18.
Operation principle:
Clarified solution behind the L-lactic acid flocculating setting; Contain the tiny biomass particle of part, get into filter housing body 1 inside from L-lactic acid flocculate and clarify liquid feed tube 5, the biomass particle is isolated in shell body 1 inside by ultra-fine filter screen 11; Progressively be deposited in the lower cone body 4; Cleaner liquid penetrates filter screen 11 and perforate cylinder 10 entering filter cores 2 inside, and the liquid valve 16 from L-lactic acid cleaner liquid outlet 15 is discharged entering concentrated refining step of step down, and this moment, blowoff valve 8 and backwashing water water intaking valve 14 were closed.
After filtering operation a period of time, the biomass fine particle can stop up filter screen 11, promptly need wash filter screen; Close L-lactic acid flocculate and clarify liquid inlet valve 6 and cleaner liquid outlet valve 16 this moment, at first opens cone bottom blowoff valve 8, will accumulate biomass suspension and discharge; And then open backwashing water water intaking valve 14, around the clear water of high pressure 0.4MPa rushes at from filter core 2 inner counter, wash away the fine particle that stops up on the filter screen 11; Blowoff valve 8 is discharged from the bottom, after the flushing, closes water intaking valve 14 and blowoff valve 8 immediately; Open feed liquor valve 6 and cleaner liquid liquid valve 16, recover normal filtration.
