The closest object, both in part of the method and in the part of the device for its implementation, is a method for producing complex organomineral fertilizer and a production line of mineral fertilizer and a production line for its implementation, in part of the method including dosing the components, mixing, grinding and sterilization by heating, mixed dry components simultaneously with sterilization, while the mixed components are heated with a gaseous coolant to a temperature of 70-80 ^o C and maintained at this temperature for at least 1 h, and after sterilization, sift, returning the screening to re-grinding.

A production line for producing complex organic-mineral fertilizer containing a dispenser, a chopper, a vibrating screen and a storage tank connected in series with transporting devices, in which, according to the invention, it has a gaseous heat carrier source connected by an air duct to the mixer internal cavity and forming a mixer-sterilizer with it, the sieve is made drum type, and the conveying devices are made in the form of screw conveyors (SU, patent 2080759, C1, IPC ⁶ A 01 C 3/00, C 05 F 3/00, C 05 G 1/10.

Karnyukhin (RU).-Application 96109636/13; Stated 05/06/1996; Publish. 10.06.1997, Bull. 16).

The disadvantages of this method include the fact that sterilization requires a gaseous coolant with a temperature of 70-80 ^o With exposure of each portion for at least 1 hour, and the fertilizers themselves contain a limited amount of essential nutrients for plants. The fertilizer preparation process is periodic. The resulting fertilizers have a powdery appearance. Drying the starting components to a moisture content of 14-18% is not economically justified. This proves the high cost of the resulting organic fertilizer. To obtain granular fertilizers, a filler of fibrous content is required. As the latter, meal of rhizomes and licorice root during extraction can be successfully used.

 The invention consists in the following.

 The problem to which the claimed invention is directed is to obtain a complex organic and mineral fertilizer balanced in terms of macro- and microelements content based on waste from primary processing and extraction of licorice root and decomposition products of cattle manure, chicken manure and pig excrement.

 EFFECT: increased yield of agricultural and fruit crops, conservation and improvement of soil fertility, prevention of pollution of soil, water bodies and atmospheric air, reduction of the cost of agricultural production.

The specified technical result in terms of fertilizer production technology is achieved by the fact that in the known method for producing complex organomineral fertilizer, which includes grinding, dosing the components, mixing, sterilizing, granulating, micronutrient sieving, sieving and regrinding the screening products, according to the invention, into two products four-year decomposition of litter and excrement of poultry, pigs and cattle add waste primary processing and extraction of licorice root determine the number of pathogenic microorganisms, sterilization of the individual components of the fertilizer is carried out bottoms extracting licorice root and natural mineral solution bishofit of formula MgCl ₂ • 6H ₂ O sulfate type 20-40% increase of required value by fine spray by continuously feeding the components into the sterilizer, and saturation macro - and trace elements in the form of crushed phosphorite and recycled sludge pickling solutions and waste metallurgical production is carried out by feeding components to granulator; decomposition products of cattle manure, pig droppings and poultry excrement are disinfected with bottoms of licorice root extraction and bischofite solution with a density of 1.2-1.4 t / m ^{3 at a} rate of 60-120; 140-180; 200-400 l / t of feedstock, respectively.

The specified technical result in terms of the device is achieved by the fact that in the production line for complex fertilizer containing a storage tank, a chopper, a drum-type separator, a dispenser, a gaseous heat carrier source connected by an air duct to the internal cavity of the drum dryer, and transporting devices in the form pipelines and screw conveyors, according to the invention, it is equipped with hoppers for dispensing waste primary processing of licorice root meal and containers for a liquid sterilizer, pump, pressure gauges, valves, a hydraulic network for feeding bischofite solution to sprayers, hoppers with dispensers for supplying macro- and microelements in the form of ground phosphorite and complex microelements from recycled sludge from etching solutions and waste metallurgical production, a granulator and additional storage tanks, hydraulically connected by pipelines with a storage tank and a bioreactor for waste treatment and mechanically connected screw conveyors with individual drum-type grinders-separators, each of which has a dispenser and is installed above the sterilizer, made in the form of a conveyor belt, while along the supply of components above the conveyor are placed sprayers for finely dispersed solution of natural bischofite mineral of the formula MgCl ₂ • 6H ₂ O for sterilization of components of organic fertilizer, while said belt conveyor is paired with a granulator.

 Due to the fact that the sterilization of the fertilizer components is carried out by fine-dispersed spraying of the bottom residue of licorice root extraction and the solution of the natural bischofite mineral, which excludes meso- and thermophilic digestion reactors from the fertilizer preparation technology, and the gaseous heat carrier is necessary only for drying the granules bound by meal fiber with dimensions 6-8 mm, to a moisture content of 14-18%. This achieves a reduction in the cost of produced organic fertilizer. The introduction of macro- and micronutrients in the form of powdered additives into the composition of organic fertilizers before granulation increases the nutritional value of the resulting organomineral fertilizer in granular form, convenient for application to the soil without polluting the environment.

 The invention is illustrated in the drawing, which shows a block diagram of a production line for complex organic fertilizer.

 Information for the implementation of the claimed complex invention are as follows.

 A method of obtaining a complex organomineral fertilizer using waste and licorice root extraction involves the following technological operations: grinding, dosing of components, mixing, sterilization, granulation, saturation with macro- and micronutrients, sieving and regrinding of screening products.

 As components of the proposed fertilizer, decomposition products of two to four years ago from cattle manure, pig droppings and bird excrement were used. They add the waste of primary processing of licorice root in the form of plant impurities, mineral litter, crushed parts of Karabash, vegetative parts, rotten roots and rhizomes of licorice and non-commodity parts, as well as licorice root meal after extraction. The ratio of the litter of poultry, pigs, cattle, primary waste and meal meal in equal proportions. In addition to these components, solid, semi-liquid, liquid organic fertilizers, manure, crop and crop residues, green manure can be successfully used to obtain the proposed organic fertilizer. The chemical composition of the mentioned fertilizers is presented in table 1. Table 2 shows the microelement composition of pig manure, which includes the excrement of cows, pigs, horses. The data presented indicate the presence of up to 20% of organic matter and trace elements vital for plants for nutrition and growth (Fe, Mn, Zn, Cu, B, Mo, etc.).

 The quantitative and qualitative composition of the starting components (manure from the farms according to the content of cattle (sample 1), litter of long-term decomposition chickens (sample 2) and fresh manure from pork from the pile) (sample 3) is carried out in table 3. This composition can be included dried wastewater sludge. The chemical composition of the latter is presented in table 4.

The amount of pathogenic microorganisms is determined in the products of two to four-year decomposition of litter and feces of poultry, pigs and cattle. Individual sterilization of organic fertilizer components is carried out by the bottom residue of licorice root extraction and a solution of natural sulfate bischofite mineral of the formula MgCl ₂ • 6H ₂ O, the ratio of these components is 1: 1. The average chemical composition of bischofite brine extracted in the fields of the Volgograd region is presented in table 5. Bischofite reserves are estimated at 200 billion tons. It was experimentally established that pathogenic microorganisms in the decomposition products of fresh cattle manure, pig droppings, and chicken excrement are completely disinfected with bischofite solution with a density of 1.2-1.4 t / m with norms per 1 ton of raw material, respectively 60-120, 140-180, 200-400 liters To increase the efficiency of processing and eliminate accidents and local untreated places, the doses are increased by 20-40% more than the required rate. Sterilization is carried out by finely dispersing a solution of bischofite and bottoms of extraction onto the surface of the crushed fraction of organic fertilizer and waste liquorice with continuous supply of components to the sterilizer.

 Saturation with macro- and microelements in the form of crushed phosphorite and recycled sludge from pickling solutions and metallurgical waste is carried out by feeding components to the granulator.

 The content of macronutrients in phosphorites mined in the Trekhostrovsky deposit of the Volgograd region, according to 2001, is presented in table 6. The chemical composition of complex mineral fertilizers using waste and extraction of licorice root, obtained on the basis of metallurgical slag and waste, spent pickling solutions, electrolytes of galvanic production and sludge of OJSC "Metallurgical Plant" Red October "(Volgograd) with subsequent granulation of the product are shown in table 7.

 Regulatory agronomic, environmental, sanitary-bacteriological and sanitary-parasitological requirements for complex organomineral fertilizer, created on the basis of decomposition products of manure, litter and excrement of chickens, pigs, cattle and natural bischofite minerals, phosphorites mined in deposits of the Volgograd region, are shown in table 8.

 After granulation due to the licorice root meal, the fertilizer obtained is dried in a drum dryer with a heated coolant to a moisture content of 14-18%. The dusty particles after sedimentation in a cyclone are recycled back to the granulator as a fertilizer component.

 The detailed chemical composition of the resulting organic fertilizer with waste licorice root is presented in table 9.

 The production line for producing complex fertilizer (see drawing) contains a storage tank 1, a chopper 2, a drum-type separator 3, a dispenser 4, a source of gaseous heat carrier 5 connected by an air duct 6 to the internal cavity of the drum dryer 7, and transporting devices in the form pipelines 8, 9 and 10 and screw conveyors 11, 12, 13 and 14 and a conveyor belt 15 for shipping the resulting product in the form of granules.

The line is equipped with containers 16 and 17 for placement of a liquid sterilization agent: container 16 is filled with the bottom residue of licorice root extraction into thick and dry extracts or glycyram. Capacity 17 is filled with brine of the natural mineral bischofite with a density of 1.2-1.4 t / m ³ . Tanks 16 and 17 are equipped with pumps 18, valves 19 and manometers 20, a hydraulic network in the form of pipelines 8, 9 for separate feeding of bottoms of licorice root extraction and bischofite brine into sprayers 21 and 22 mounted on rods 23 and 24.

 The line is equipped with bins 25 and 26 with dispensers 27 for supplying macro- and microelements from recycled sludge from pickling solutions and metallurgical waste and phosphorite flour extracted from deposits in the Volgograd region, granulator 28 and additional storage hopper 29 for collecting the initially worked-out mixture of organic waste and fertilizers from cattle, poultry and pig farms when applied to the surface of the irrigated and non-irrigated fields by the scattering method or by spreaders of organic fertilizers ROU-6 (ROU -8), or a converted 1-PMT-4.0 uniaxial mineral fertilizer spreader.

 A drum dryer 7 is connected by an air duct 30 to a centrifugal cyclone 31. In the upper part of the cyclone 31 there is a fan 32 with a drive and a pipe 33 for venting flue gases to the atmosphere. At the bottom of the cyclone 31, a dispenser 34 is placed and, by means of a screw transport 35, is connected to a conveyor 36 for preparing fertilizer components for granulation. Granulator 28 is connected by a conveyor belt 37 to a drum dryer 7.

 The line is equipped with metering hoppers 38 and 39 for supplying, respectively, licorice root meal and wastes of primary processing of licorice. To unload liquorice processing waste, car lifts 40 and 41 were mounted in front of the hoppers 38 and 39 for unloading the raw materials. For the processing of liquorice waste, a chopper 42 of non-standard roots, a Karabash and licorice stubble, and a mixer of 43 mineral litter and plant impurities were mounted behind the hopper 39. The hopper 38 and the mixer 43 screw conveyors 14 are connected to the conveyor 36.

 Dispenser 4 is kinematically connected with tanks 44, 45 and 46 for separate collection of semi-finished products for processing poultry excrement, pig droppings and cattle manure.

 In front of the storage tank 1, a third car lift 47 is mounted.

 The storage tank 1 is hydraulically connected to the pipeline 10 with a drive 48 and a hopper 49 drains. Semi-dry product from the bioreactor through the conveyor 50 is transferred to the granulator 28. In the network, a bioreactor 49 and a drain accumulator 48 are provided with a fecal pump 51.

 When performing the technological process, to expand the functionality of the line, a screw conveyor 52 is provided for direct delivery of one or another semi-finished product to the conveyor 36. The direction of supply of fertilizer components by conveyor 36 is shown in the drawing by an arrow.

 The technological line works as follows.

 Wastes of primary processing of licorice, meal and bottom residue during extraction of licorice root to the line are transported by road. Decomposition products of two to four-year decomposition of cattle, pigs and poultry manure from near-farm manure depots by road and dump tractor carts are delivered to their processing point. One production line serves several adjacent farms, a plant, licorice and feed farms, poultry farms, pig farms, cattle farms, etc.) By a car lift 47, the decomposition products of organic fertilizers and waste from licorice and meal are unloaded into a storage tank 1.

 The moisture content of the starting components can vary over a wide range. For this reason, excess moisture and effluent from organic fertilizers along concrete inclined walls due to gravitational forces flow down into the collectors below and through pipeline 10 by gravity to the 48 waste water collector. From the accumulator 48, the effluent by the fecal pump 51 is periodically fed to the bioreactor 49 for processing the effluents into solid fertilizers. In bioreactor 49, anaerobic methane-acid fermentation occurs. To accelerate the fermentation process, the bioreactor 49 is heated by the exhaust and flow gases of a drum dryer 7 or a heat source 5. The separated solid component from the bioreactor 49 is fed by a screw conveyor 50 to the granulator 28.

Fertilizer components in predetermined portions by screw conveyors 11, 12, 13 from the storage tanks 44, 45 and 46 are fed to the conveyor 36. Prior to this, foreign inclusions in the form of stones (pieces of brick, gravel, slate fragments, metal) are separated from the storage tank 1 and the separator 3 conveyor parts, knitting wire, wood chips and wood, etc.) are separated from the total mass and fed by conveyor 41 to the technological litter accumulator with subsequent disposal. From the separator 3 by the conveyor 52 or in metered portions in case of improper movement of the screw conveyors 11, 12, 13, the fertilizer components are laid in a thin layer on the surface of the conveyor 36. The direction of supply of components in the drawing is shown by an arrow. With the conveyor drive 36 turned on, the surface of the components of organic fertilizers and waste of licorice and licorice meal is dispersed in a thin layer at a dose of 60-120 l / t of cattle manure, at a rate of 140-180 l / t of pig droppings and a flow rate of 200-400 l / tons of bird excrement serves a sulfate-type bischofite solution with a density of 1.2-1.4 t / m ³ . Finely dispersed bischofite solution is conducted at a pressure of 0.03-0.05 MPa. Pressure control is carried out by pressure gauges, and fluid flow rate by valves 19. To exclude marriage and reliability of sterilization of components, the consumption rates of bischofite solution are increased by 20-40% more than the required value. Magnesium chloride hexahydrate (MgCl ₂ • 6H ₂ O) destroys microflora in organic components and saturates them with microelements. The content of the latter in bischofite solution is given by us in table 5.

This operation is duplicated by feeding the bottom residue of licorice root extraction from the tank 16. The layered laying of the fertilizer components on the surface of the conveyor belt 36 and their sterilization contribute to uniform volumetric processing of the components. The feedstock for producing granular organic fertilizer is sent by conveyor 36 to granulator 28 and at the same time macro- and microelements in the form of powder, ground phosphorus and complex microelements from recycled sludge of pickling solutions and metallurgical waste products are fed from hoppers 25 and 26. Un-dried components of fertilizers with an initial moisture content of up to 30-36% contribute to the production of complex fertilizer granules with sizes from 15 to 22 mm. Fertilizers in the form of raw granules are fed from granulator 28 to a drum dryer 7. A coolant with a temperature of 120-140 ^° C is supplied to dryer 7 from source 5. The spent drying agent from cyclone 31 enters the absorber, where the clarified fraction from bioreactor 49 is simultaneously fed.

 Granules with a moisture content of 14-18% from a drum dryer 7 are fed to a weighing device for further feeding by conveyor 15 to a bag sewing device or to a container for long-distance transportation.

 The effect of the proposed granular complex organomineral fertilizer on the yield, grain quality and disease susceptibility of winter wheat Triticum aestivim L, emend, Fiori et Paol of several varieties is presented in table 10. The effectiveness of the use of complex organomineral fertilizer for cultivating spikes under production conditions is shown in table 11. The soft winter wheat Triticum aestivim L, emend, Fioritt Paol varieties Don 93 with a bread sawfly, depending on the type of fertilizer applied for the main tillage, bring on table 12. The structural analysis of barley crops of variety Donetsk 8 on the fields of SPK Rodina in the Danilovsky district of the Volgograd region in the 2001 season using different types of fertilizers is described in table 13, and the comparative economic yield on a production field of 210 ha in the subsidiary of ZAO "Feed" Gorodische district - in table 14.

 The estimated cost of 1 ton of complex organic fertilizer in 2000 prices is presented by us in table 15.

 Thus, the data presented indicate the receipt of high-quality organomineral fertilizer without preliminary drying of components based on decomposition products of 2-4 years old cattle manure, pig and chicken litter.
