Description

The invention relates to a device for disintegrating the biomass of microorganisms in the production of physiologically active substances as a biostimulant additive in animal feed to reduce their consumption and can be used in wastewater treatment plants, preferably in agriculture.

The purpose of the invention is the increase in stele, nor disintegration .. ,,

In FIG. 1 shows a longitudinal section through the device of B-C-D in FIG. 2; in FIG. 2 is a section AA in FIG. 1; in Fig.3 - the same section; in FIG. 4 is a section through a channel between wedge-shaped inserts; in FIG. 5 is a flow chart of the production of physiologically active substances for supplementation in animal feed.

A device for disintegrating the biomass of microorganisms comprises a horizontal cylindrical body 1 with a profiled toothed inner surface of the wall 2 and with nozzles 3 for supplying the disintegrable biomass and 4 of the disintegrant, and a horizontally mounted working disk 5 with a gear edge 6, on the upper surface of which vertical projections 7 are arranged uniformly around the circumference. On which wedge inserts 8 of elastic material are mounted, with the formation of tapering between their side surfaces to the periphery of the channels 9 for the passage of disintegrable biomass and having vertical grooves 10 and protrusions 11 in these channels on their surface to create a pressure differential along the biomass. Profiled toothed surface of the wall 2 of the housing 1 and insert 8 is made of a composite material including particles

12 abrasive, while the surface of the wall 2 is toothed, the surface of the inserts 8 on the edge b of the working disk 5 and the vertical grooves 10c with the protrusions 11 on the surface of the inserts 8 in the channels 9 between the inserts 8 have a triangular cross-sectional shape in cross section.

A device for disintegrating biomass by a microorganism operates in the installation at 13, and includes a sand trap 14, an arc trap 15, filtering centrifuges 16 and 17, a biogenerator 18, including chambers 19 arranged successively along the height, separated by perforated 20 and solid 21 horizontal partitions forming blast chambers 22 with nozzles 23. Chambers 19 are interconnected by nozzles 24 and equipped with a nozzle for immobilizing microorganisms in the form of flexible threads 25. The upper chamber 19 is made with pat a compartment 26 of an air outlet and a branch pipe 27 for supplying sewage, and a lower chamber 19 with a branch pipe 28 for removing biologically purified water with a biomass of microorganisms into a chamber 29 for processing biomass into a commercial product. The installation includes a fermenter 30 and a digester 31.

A device for disintegrating the biomass of microorganisms in a plant operates as follows.

Preferably, sewage from an agricultural farm, such as a pig farm, enters a sand trap 14 for separating heavy suspensions and an arc separator 15 for separating the lungs; additional separation of suspensions is carried out in a centrifuge 16. Suspensions from a sand trap 14 and an arc sieve 15 are sent to a solid phase fermenter 30. and from the filtering centrifuge 16 to the digester 31. For the wastewater freed from suspensions, the nutrient elements are adjusted, and the wastewater from the nozzle 27 enters the biogenerator 18 into its chamber 19, where, by air purging, we supply passing through the nozzle 23 and flowing out through the perforated partition 20 from the blasting chamber 22, the biomass of microorganisms grows on the biogenic components of the effluents in the presence of flexible threads 25 as immobilization for microorganisms. The effluents sequentially flow through the nozzles from the overlying chambers 19 to the underlying ones with exhausted power elements microorganisms settled on flexible threads 25. The sewage from the biogenerator 18 through the pipe 28 with the biomass suspended in them enters the centrifuge 17 to separate it and. The disintegrated biomass through the pipe 3 enters the channels 9 narrowing towards the periphery between the wedge inserts 8 located on the vertical protrusions 7 of the working disk 5. In the channels 9, microorganisms disintegrate by pressure drops between the channels 10 and the protrusions 11 and erosion by particles

abrasive 12 of the composite material of insert 8. Additional disintegration is carried out by hydrodynamic action and erosion of microorganisms between the profiled gear surface of the wall 2 of the housing 1 and the gear edge 6 of the inserts 8. The disintegrate is discharged along the tangential branch pipe 4. Excess disintegrate enters the chamber 29, for example, a sterilizer, for subsequent use as a feed additive. Processing biomass into disintegrate makes nucleic acids, enzymes, vitamins and trace elements, which are biostimulants for improving absorption of the rest of the feed, more accessible for animals and birds to digest.
