Description

The present invention relates to agriculture and is intended for the mechanization of animal husbandry and processing of manure.

Known machines for keeping pigs, in which they make a heat-insulating layer in the floor, heat the floors and remove manure through the channels of the manure removal system into storage lagoons (KTO-F-10, etc.). At the same time, there is a significant environmental degradation and loss of nutrients from manure (Lagoons - manure storage, leaflet, Agropromizdat, No. 5, 2008).

Flexible tanks for storing liquid manure from AVOMOSR are also known (Leaflet of West, 2009). The disadvantage of these devices is that they only serve to store farm effluents, and for the subsequent processing of effluents into environmental components (biogas, fertilizers) they must be transported to devices for its implementation.

There was a need to create a technological system for keeping animals, in the machines of which animals are kept, and in flexible tanks used to collect, accumulate and store liquid manure, it is being processed into biogas and fertilizers.

The technical result is to improve the ecological condition of livestock farms, accelerating and cheapening the process of processing liquid manure into biogas and fertilizers.

The technical result is achieved by the fact that the technological system for keeping animals and processing farm effluents, including machines for keeping animals, containing a gate on the front wall, a feeder on the rear wall and a drinker on the side wall; dung channels and a tank for collecting slurry, is additionally equipped with a gas tank; the machines are installed on the concrete floor between the manure channels, the manure channels are biased towards the pumping station; as a tank for collecting slurry, it uses flexible tanks made of high-strength fabrics and coated with heat-insulating materials and installed directly on the floor of the machines, while the flexible tank is both a drive for storing slurry and a reactor for biogas and fertilizer with a gas tank - flexible tanks are connected to pump station and gas holder through flexible hoses and equipped with purge valves, electrotenes and gate valves; a hydrant is installed above the flexible tanks, and animals placed in the machines carry out the mixing of slurry.

Placing the machines on the concrete floor between the manure channels will make it easy to remove manure and reduce the distance of its transportation to the tank for collecting slurry, which will not only reduce the harmful effects on the environment, but also accelerate the process of processing farm effluents.

The slope of the manure canals towards the pumping station will speed up the processing of farm effluents without additional costs.

The use of flexible L-shaped tanks made of high-strength fabrics and coated with heat-insulating materials will make it possible to use them not only as a drive for storing slurry, but also as a reactor for biogas and fertilizing with a gas tank, which will reduce the cost and speed up the process of their production.

Placing flexible L-shaped tanks directly on the floor of the machines will make it possible to reduce the cost of processing farm effluents by reducing the distance of their transportation to the processing site.

The purge valves of the flexible L-shaped tanks are designed to start the anaerobic process, which will speed up the process of disposal of farm effluents.

The use of electrotenes inside flexible L-shaped reservoirs will allow maintaining the mesophilic process of wastewater processing at a given temperature in automatic mode, which helps to accelerate and reduce the cost of processing farm wastewater.

The supply of flexible tanks with gate valves will speed up the process of unloading the final product, which will reduce the cost of its production.

Equipping the technological system with an additional gas tank will allow storing biogas allocated during the fermentation of farm effluents and use it for its intended purpose, which will reduce the cost of utilizing farm effluents.

The use of animals housed in machines for mixing slurry in and thermal energy of the body of animals for heating biomass in flexible tanks will reduce the cost of processing farm effluents.

The technological system of flexible drains for keeping animals and processing drains of farms includes machines 1 for keeping animals, installed on the concrete floor of the room and located between the manure channels 8, 10. Manure channels 8 have a slope towards the pumping station 11. Directly located on the floor are L-shaped tanks 2, 3 for collecting, storing and processing farm effluents into biogas and fertilizer. Flexible tanks 2, 3 are made of high-strength fabrics and coated with heat-insulating materials. Flexible reservoirs 2, 3 are connected to the pumping station 11 and gas holder 12 by means of flexible hoses 13, 14. Flexible reservoirs 2, 3 are provided with purge channels 15, 16 with electrotenes and valves. A hydrant is installed above the flexible tanks 2, 3. Machine tools 1 for animals contain wickets 6 on the front wall, a feeder 18 on the rear wall and a drinker 17 on the side wall.

The technological system for keeping animals and processing farm effluents works as follows.

Animals (pigs) are driven into the machines 1 through wickets 16 and placed on flexible tanks 3. The feed is poured into feeders 18, water is fed to drinking bowls 17. As manure accumulates on flexible tank 3, it is washed with water from the hydrant into the manure channels 10, of which slurry enters the pump unit 11. From the pump unit 11, slurry is pumped through hoses into flexible tanks 2, 3 daily. After filling the tank 2,3 include electroten installed inside the flexible tanks, and heated slurry to 35 ° C. Through the purge valves 15, 16 of the flexible tanks, the exhaust gases of the internal combustion engine are purged, the air is displaced from the flexible tanks and anaerobic conditions for processing slurry are created. Animals moving along the surface of the flexible tank 3 mix the biomass in it, thereby providing optimal conditions for the fermentation and release of biogas. Dedicated biogas through flexible hoses 13, 14 enters the gas tank 12 and the side walls, and then it is used for its intended purpose. After fermentation is completed, after 15-23 days, slurry processed into fertilizer is unloaded through valves 7 and transferred to the consumer for intended use. Tanks 3, 2 are again filled with slurry and the process of processing farm effluents is repeated.

Thus, waste-free processing of farm effluents is carried out, which will improve the ecological state of livestock farms, speed up and reduce the cost of processing liquid manure into biogas and high-quality fertilizers.

The technological system for keeping animals and processing farm wastewater was manufactured and tested at the Rassvet industrial holding, GNU SKNIIZH at STF-1 in 2010.
