Description

The invention relates to feed production, and in particular to a line for the preparation of feed molasses and effective easily digestible liquid feed (feed pastes) from various mixtures of plant and animal products, trace elements, protein, fat, vitamin and mineral additives that are used for growing young animals and supplementary nutrition of adult farm animals, and can be used for the preparation of feed from cereals, legumes, vegetables, and coarse-stem crops that go to the diet of agricultural enterprises egg animals, as well as pigs on subsidiary, farm and collective farms.

Known installation for the preparation of multi-component feed according to the author's certificate of the USSR No. 1371684, class. A23N 17/00, publ. 02/07/1988, which includes a container for the initial product, a pump, a compensation tank with primary and secondary pressure control devices, a flow switch, a disperser installed between the flow switch and an additional valve, a hydrodynamic resistance simulator made in the form of an inverted cup, overflow pipe, separator with two exits and a highway.

This installation has a complex and time-consuming design, at the same time carries out the preparation of feed only at the initial stage.

A known line for the preparation of feed from coarse plant materials according to patent RU No. 2091040, class. A23K 1/12, publ. 09/27/1997, which includes a chopper, processing device, phase separator, mixers, batchers, hoppers for collecting the final product, connected by a piping system to a pump, a closed system for cyclic processing of raw materials, a dispersant with circulation tanks that are connected to the dispersant through a multi-position valve the system.

The disadvantage of this analogue is the presence of complex systems for connecting devices in the line, which negatively affects the reliability of its operation, in addition, the functionality of the line is limited, due to the fact that the dispersant can process only pre-shredded crops.

The closest technical solution to the claimed device for the combination of essential features is the installation for the preparation of liquid feed (Russian patent No. 2261621 class. A23K 1/14, publ. 10.10.2005), which includes a hopper for preliminary mixing of the original feed (grain, crushed plants, food waste, etc.) with water, inlet and outlet pipelines, shut-off valve, mixing chamber, grinding and heating, nozzles, rotor, large and small blades, drain valve, electric motor and control devices.

The device operates as follows. The hopper is filled with water to a certain level, to which the feed components are added, in the required proportion, then the shut-off valve is opened and the electric motor is started. The feed mixture passes through the inlet pipe through the inlet pipe to the grinding chamber. The mixture passes through the channels of the mixed section of the rotating rotor, is subjected to hydrodynamic, cavitation and thermal effects, and then, passing the channels of the rotor and stator, is sent through the outlet pipe to the hopper. A similar cycle of the feed preparation process is repeated many times. Repeated circulation of the feed mixture through the chamber in a closed loop leads to a gradual decrease in the particle size of the mixture, structural changes, decrease in fiber content, the destruction of toxic fungi and its gradual heating. The resulting feed has high quality, softness, good digestibility due to structural transformations of the feedstock and is suitable for feeding young animals.

The disadvantages of the known installation for the preparation of feeds are: not effective retention of feed components in suspension in water and clogging of the inlet pipe and pipeline that have settled on the bottom of the grain; the absence of traps in the system, which, with high grain hardness and the presence of inseparable small stones and sand particles in it, will lead to accelerated formative-cavitation wear of the mating surfaces, and then a sharp decrease in the installation efficiency, up to emergency situations.

The objective of the complex proposed for patenting is to create a simple line in operation of a prototype free from defects.

The technical result consists in creating a simple operation line with enhanced functionality, by creating conditions for the operation of each unit, both individually and in a single technological process at the same time two of its units.

The use of the complex allows you to reduce energy, material and labor costs by combining several technological processes in the preparation of feed, to destroy mold and preserve vitamins and minerals.

The claimed technical result is achieved by the fact that in the installation for preparing liquid feed, which includes a container for pre-mixing, connected by suction and pressure pipelines, respectively, with the inlet and outlet nozzles of the grinder connected to the drive, thus forming a closed circulation loop for processing feed, according to the claimed solution, the chopper is made in the form of a dispersing pump, while the number of containers for mixing is set to at least two, and the number of pumps is dispersants - at least two, and, tanks for pre-mixing are connected to pump-dispersants through a system of suction and pressure pipelines equipped with control valves, with the possibility of creating a single technological process for preparing liquid feed or autonomous conditions for the operation of each tank separately, and the installation additionally contains traps located on the branches of the suction pipe in front of the inlet nozzles of the dispersing pump.

The complex provides uniform fine grinding, mixing, homogenization and heating of organic and mineral materials with low mechanical strength in a liquid carrier medium. The main purpose of the installation is the preparation of feed molasses and effective easily digestible liquid feed (feed pastes) from various mixtures of plant and animal products, trace elements, protein, fat, vitamin and mineral additives that are used for growing young animals and supplementary nutrition of adult farm animals in auxiliary , farms and collective farms.

The complex is a batch process equipment and is serviced by one operator. The choice of liquid feed formulation is determined by the consumer depending on the type and age of the animals, their feeding season. The complex is designed for operation in closed heated rooms in temperate and cold climates. Productivity of the complex is 3.5 t / shift. The complex uses tap drinking water.

Mixer tanks serve as reservoirs for loading and mixing portions of raw materials by hydroflow, preparation and storage of the finished product. Mixer tanks are welded tanks with top loading and lower conical discharge. To control the filling of the working fluid, a water meter is installed. The working bodies of the complex are dispersing pumps based on serial pumping units.

The principle of the complex is multiple circulation of the mixture through tanks and dispersing pumps. In this case, grinding, mixing and volumetric heating of the mixture of starting materials and liquid in the system "tank-mixer-pump-dispersant-tank-mixer" and the enzymatic conversion of the mixture into readily available simple sugars takes place. The temperature mode is controlled by a thermometer. The cooking process is completed in accordance with the technological regulations for the preparation of feed.

The complex is mounted from ready-made blocks (mixing tanks, dispersing pumps, pipeline circuit) directly at the installation site.

Before starting the cooking process, it is necessary to conduct complex testing and running the complex on water, for which

- close the drain taps located at the bottom of each of the three mixing tanks;

-sequentially pour into each of the three mixing tanks the maximum working volume of water with the temperature required for a particular process;

- turn on the dispersing pump in the work, dispersing pumps 6 are driven by motors;

- making sure that the pumps are operating in normal mode, and the shut-off and pipe valves are technically serviceable, continue the process until the water temperature reaches 50 ° C,

- open the drain cock and drain the water into the sewer.

Complex for the preparation of liquid feed is as follows.

Mixer tanks are filled with the required amount of water and grain, approved in the feed formulation. Before filling, it is necessary to make sure that there are no mixers, tools, or debris in the mixer tanks, pumping units, technological site, service area, passageways and evacuation routes. Close the drain cock and fully open all control valves. The required amount of water is poured into the first mixing tank in accordance with the approved feed formulation. Turn on the dispersant pump and check the circulation of the liquid in the mixer tank. Turn on the boot device - auger and sequentially load the original components of the feed. The percentage of dry feed loaded into the mixer tank, not more than 30% of the volume. The size of the pieces of dry feed loaded into the mixer tank is determined by the design of the dispersing head and should be no more than 10 mm. During the operation of the complex, the temperature of heating the liquid feed is controlled. Feed paste is ready when the temperature reaches 41 ° C, feed syrup - 60 ° C. The finished product is drained using any dispersing pump through a drain valve. After emptying the mixer tank, turn off the dispersant pump, close the drain valve and pour the required amount of water into the mixer tank to prepare the next batch of liquid feed. The duration of the liquid feed preparation cycle, at the maximum load of the installation, is not more than 2.5 hours. Power consumption and current strength, at maximum load, not more than 45.0 / 63-66 kW / A. The particle size fraction of the feed paste is not more than 0.5 mm. The design provides for the autonomous operation of one of the tanks or all mixing tanks at the same time, depending on the required amount of feed. The autonomous operation of the complex is achieved by closing or opening the corresponding control valves installed on the branches of the pressure and suction pipelines, which ensure the circulation of the mixture from the dispersing pumps to the mixing tanks and back to the dispersing pumps. To obtain the maximum effect, it is advisable to use the entire volume of the complex. Then there is repeated circulation through the working bodies of the dispersant pumps.

When temperatures reach 50-60 ° C, the process of preparing the processed volume is completed and after cooling, the mass is fed to livestock feed. The resulting feed has high quality, softness, good digestibility due to structural transformations of the feedstock and is suitable for feeding young animals.

The use of the complex in agriculture will reduce energy, material and labor costs by combining several technological processes in the preparation of feed, destroy molds and preserve vitamins and minerals.
