No. 1 // Inventions. - 1997. - No. 16).

The disadvantages of this line include limited functionality.

The invention consists in the following.

The problem to which the claimed invention is directed is to obtain a complex granular organic-mineral fertilizer based on substandard waste of vegetative mass, products of threshing beans and licorice seeds and products of 2-4-year-old decomposition of pig manure from the liquid fraction in sedimentation tanks near pig farms, bird droppings, phosphorites and bischofite, extracted from the bowels of the Volgograd region, as well as waste from industrial enterprises of the city of Volgograd .

EFFECT: increased yield of field agricultural crops in irrigated and non-irrigated agriculture, preservation of soil fertility, reduction in the cost of agricultural production in the form of animal feed and grain for the population.

The specified technical result in terms of the technology for the production of granular fertilizers is achieved by the fact that in the known method for producing organomineral fertilizers, comprising mixing bird droppings with phosphorus, nitrogen and potassium components and supplementing with microelement additives, according to the invention, vegetative waste products are used as an organic filler threshing beans and substandard licorice seeds naked, and as phosphorus-containing components - double superphosphate from phosphorito howls of flour and sludge from the settlers of pig farms, a nitrogen-containing component - bird droppings of two to four years of decomposition, and as a potassium-containing component - manure from temporary storage areas near pig farms, and micronutrient additives are added in the form of ground and processed sludge from etching solutions and metallurgical waste and a solution of the natural bischofite mineral, supplemented with a binder material - paraffin-containing waste - of a refinery, while mixing is carried out for 20- 50 minutes, and a solution of the natural bischofite mineral and paraffin-containing wastes are fed into the mixer at a temperature of +60 ... + 90 ° С.

The effect and technical result in terms of the device is achieved by the fact that in order to obtain granular organic-mineral fertilizer, in which, during the technological process, kinematic and mechanical means of transporting the processed raw materials are installed in series, the droppings accumulator, a centrifuge connected by a pipeline for draining the liquid fraction with a drain accumulator , devices for mixing raw materials and drying them with hot air, raw materials storage bin and conveyor for dispensing finished products According to the invention, it is equipped with a grinder of vegetative mass, products of threshing beans and substandard licorice seeds and containers hydraulically connected with them with shut-off elements and pumps for supplying liquid-containing nozzles of paraffin-containing waste and a solution of natural sulfate bischofite mineral of the formula MgCl ₂ · 6H ₂ O and metering hoppers for separate dosed supply of phosphorite flour and complex powdered microelements from sludge from etching solutions and metallurgical waste production, while the mixer of organic fertilizer components by screw conveyors is kinematically connected with raw material storage bins in the form of 2–4-year-old poultry manure, sludge from settling tanks and 2-3-year-old pig manure and cattle manure of 2-year decomposition, a centrifuge and an extruder-granulator, with the latter conveyor belt connected to a drum dryer.

Due to the fibrous materials from the vegetative waste products in the production of perfumes, including creams, lotions, shampoos, and threshing products of beans and substandard seeds of licorice (Ural licorice, GG Korzhinsky licorice, etc.), crushed cattle manure is bound , litter of pigs, poultry excrement, mineral additives and obtaining moisture-resistant granules of the proposed complex fertilizer. Fillers of the proposed fertilizer contribute to soil formation processes and reduce wind, water, solar soil erosion.

The invention is illustrated by drawings.

Figure 1 presents the technological platform for the primary part-time runoff and litter of poultry and pigs and manure from cattle farms.

Figure 2-5 shows the site for part-time manure of cattle, sludge from sumps and litter from pig farms, from sumps to separate the liquid fraction of bird droppings.

Figure 6 schematically shows a plant for producing complex organic fertilizers based on poultry manure, pig manure and cattle bedding with the addition of ground phosphorite, bischofite brine and sludge from etching solutions.

Information confirming the possibility of implementing the claimed invention are as follows.

Pig droppings from farms 1 with a hydraulic wash are sent to sedimentation tanks 2 (see figure 1). In each sump, 2 pig droppings and process water are precipitated. Under the influence of gravitational forces, silt particles and suspensions settle in the bottom of the settling tank 2. As the water clarifies, the latter is sent to the pool 3. The sludge is discharged from the settling tanks 2 and stored in bales at sites 4 and 5. Sumps with silt at sites 4 and 5 each 2-3 months are interrupted and Bischofite brine is added to combat pathogenic microorganisms.

Litter and bedding from cattle farms 6 are transported by conveyor devices to platform 7, where they are stored. To obtain organic fertilizer from cattle manure in the summer, every 1-2 months it is interrupted, i.e. mix the upper, middle and lower layers, so that the entire mass of manure is involved in the course of the thermophilic anaerobic process.

Litter (dry) from poultry farms 8 is delivered either to platform 7, or litter (wet, wet) to platforms 9 and 10, where process water is removed from it. In specialized cattle fattening farms, pork or poultry production, only sites 4 (5, 7) or settling tanks 2 with sites 9 (10) are performed.

The production of complex organic-mineral fertilizers is organized in one of the large farms, as close as possible (minimally remote) and connected by a network of roads with a number of lying farms specializing in the feeding and raising of certain animal species and industrial enterprises.

From the nearest households, organic fertilizers of 2-4-year-old decomposition by vehicles are transported to specially prepared sites 11-14 for pre-processing manure of 2-3-year-old decomposition with an area of 4 hectares (see figure 2), dry bird droppings (figure 3) , the litter of pigs of 2-4-year-old decomposition with an area of 2 hectares (figure 4) and sedimentary chambers on an area of 1 hectare for the processing of sludge from the settlers of pig farms (figure 5).

As technological equipment 15, truck scales, a separator for separating coarse impurities from raw materials and a tractor loader PB-75 based on a caterpillar tractor DT-75M are located on site 11.

Area 12 (figure 3) with an area of 2 hectares is also fenced and equipped with separators 17 for the primary part-time work of chicken manure. Silos 18 are placed above the separators 17 for storing underworked raw materials.

Platform 13 (figure 4) has technological equipment for the separation and loading of pig droppings into vehicles.

Platform 14 (figure 5) with an area of 1 ha is equipped with centrifuges 19 for separating water from the sludge.

A method for producing granular organic-mineral fertilizer involves mixing manure with phosphorus, nitrogen, and potassium-containing components and supplementing with trace elements. As raw materials and initial components in the workshop for the production of granular organic fertilizers, these materials from sites 11-14 are delivered by vehicles. As a phosphorus-containing component, double superphosphate is used from phosphorite flour and sludge from the settlers of 2 pig farms 1, or from sites 4, 5, or from site 14. The characteristics of the phosphorites mined in the deposits of the Volgograd Region are shown in Table 1. Birdlike is used as the nitrogen-containing component litter of 2-4-year-old decomposition, delivered either from sites 7 (figure 1), or from site 12 (figure 3). The chemical composition of the processed bird droppings is presented in table 2.

As a potassium-containing component, litter from sites 4 and 5 of temporary storage near pig farms 1 was used.

Supplementation with trace elements is carried out in the form of ground and processed sludge pickling solutions and waste from metallurgical production and a solution of the natural mineral bischofite. The content of trace elements we have shown in tables 3 and 4.

Paraffin-containing waste from an oil refinery (Volgograd) was used as a binder material for components of organic fertilizers (manure, litter, silt). Before granulating the fertilizer components, they are treated with a solution of the natural bischofite mineral and paraffin-containing waste heated to 60-90 ° C. The treated mass in the mixer is stirred for 20-50 minutes. Submitted homogeneous mass is sent to an extruder granulator. Granules with a size of 5-10 mm are dried in a drum dryer at a temperature of a drying agent of 110-140 ° C. Granular fertilizers are packaged in kraft bags or corrugated packaging of 3-5-layer cardboard weighing 20-50 kg. Finished products are sent by road to the consumer.

The complex granular organomineral fertilizers obtained by the described method have a shelf life of up to 5 years and are easily applied to the soil by all types of available agricultural machines. The characteristics of fertilizers are given in table 5.

The installation (see Fig.6) for the production of granular organic-mineral fertilizers during the execution of the technological process contains sequentially installed and interconnected kinematic and mechanical means of transporting the processed raw materials, the litter drive 20, a centrifuge 21, connected by a pipe 22 to drain the liquid fraction to the drive 23 a drain, a device 24 for mixing the raw materials, a dryer 25 for drying it with hot air, a storage hopper 26 for the raw materials and a conveyor 27 for dispensing finished products 28.

It is equipped with a car lift 47 for unloading airborne vehicles, a pit 48 and a separator 49 for separating acceptable fractions and foreign materials before feeding the organic fertilizer components. Conveyor 50 removes the unseparated waste of organic fertilizers and litter outside the canopy for subsequent disposal.

Under the canopy, a grinder 51 of vegetative mass, threshing products and substandard licorice seeds equipped with an electromechanical drive is installed. As the latter, Volgar-5 or RCC-6 machines can be used. Chopper 51 is kinematically coupled to extruder granulator 43.

Installation for producing granular organic fertilizer works as follows.

Pre-worked components of organic fertilizers from platforms 11-13 by road and dump truck tractors (PTS-4, PTS-9, PSE-12B) are delivered to the heap pit 48. From the heap pit 48, organic fertilizers enter the separator cavity 49. Separator 49 from litter, non-ripened plant residues, stones, metal inclusions, dressing materials of hay and straw bales are separated. The conveyor 50 described impurities are removed outside the installation, first stored and then disposed of.

Separation products from under the separator 49 are separately transported to the storage hopper 26 to accumulate the reserve mass of 2–4-year-old chicken manure, 2–3-year-old pork manure, 2-year manure decomposition and cattle litter . From the storage bins 26 screw conveyors 38-40 components are fed into the device 24 for intensive mixing of the feedstock. When semi-dry or waterlogged bird droppings and / or sludge are delivered from settling tanks 2 located in the nearest pig farms 1, the raw materials are first fed to a drive 20, and then to a separator 21, and from there by a screw conveyor 41 to the device 24. When the drum of the device 24 is rotated, the components fertilizers from a centrifuge 21 and storage hoppers 26 are converted into a homogeneous, homogeneous mass. At the same time, with the continuous execution of the technological process, phosphorite flour and complex microelements from sludge from pickling solutions and metallurgical production wastes are supplied in strictly dosed quantities from batchers 36 and 37.

To create the initial wet raw material before the production of granules into the device 24 under a working pressure of 0.6-0.8 MPa from the tank 30 serves a heated brine of the natural bischofite mineral of the formula MgCl ₂ · 6H ₂ O with a density of 1.2-1.14 t / m ³ 30-120 kg per initial ton of raw materials. Bischofite is sprayed with a nozzle in the drum cavity of device 24. From tank 29 heated to a temperature of 60-90 ° C with a pump 32, paraffin-containing waste from an oil refinery is delivered through a pipe 34 to the cavity of device 24. The described waste is applied as a binding material to the continuously mixed components with a nozzle in a finely divided form. organic and mineral fertilizers. After 20-50 minutes, the processed mass from the device 24 by the screw conveyor 42 is sent to the extruder-granulator 43. At the same time, the ground mass of licorice waste is also fed therein in the production of seed material and raw materials from the vegetative mass for perfumery. Compressed granules with a size of 5 × 8 × 10 mm by conveyor belt 44 are continuously sent to the cavity of the drum dryer 25. Dust and exhaust gases are discharged from the dryer cavity 25 by a counter-directed agent of the furnace 45, which are sent to the cyclone 46 through the air duct. The purified air from the cyclone 46 is discharged outside the installation area, and the dust particles are re-fed to the device 24.

Dried granules from the cavity of the drum dryer 25 are fed to the conveyor 27 of the issuance of finished products 28.
