Description

The utility model relates to agriculture, in particular to devices for making liquid enrichment additives in dry feeds on livestock farms and complexes.

A device for mixing dry feed and liquid additives [Pat. No. 2336690 Russia, MPK A01K 5/00, BI No. 30, 10.27.2008], consisting of a hopper for dry feed with a discharge neck, inside of which a discharge screw is installed. In the lower part of the discharge neck, a grid is installed under which a humidification chamber with nozzles is located. A mixing chamber is installed under the humidification chamber, inside of which there is a mixing auger with an unloading chute and an adjustment flap, as well as a liquid additive supply system.

The disadvantages of the known device are the complexity and necessity of manufacturing a design of high accuracy.

A device for mixing dry feed and making fat additives [Pat. No. 2297780 Russia, IPC A23N 17/00, BI No. 12, 04/27/2007], consisting of a mixing chamber having a loading hatch and an unloading chute, a two-way mixing auger enclosed in the upper and lower casings fixed in the mixing chamber in the middle part 8-10 mixing blades are radially mounted on the mixing auger, and 4-6 mixing blades in the lower part. The mixing auger is driven from the gear. In addition, the mixing chamber in the upper part is tangentially connected by a feed line to a device for making fat additives having an adjusting screw.

The disadvantages of this device are the high complexity of the manufacture of the structure, the high energy intensity of the mixture formation, the adherence of fat particles to the feed pipe, and the inability to use the device in continuous mode.

Known installation for heat treatment of grain and animal feed [US Pat. No. 2280396 Russia, IPC A23N 17/00, BI No. 21 07/27/2006], which contains a cylindrical working chamber with a truncated-conical base, ring-shaped electric heating elements mounted on the outer cylindrical surface of the chamber, thermal insulation of the working chamber, protective cover, enclosing thermally insulating working chamber. A loading lock is placed on the top cover of the working chamber along the central axis, and nozzles for injecting water and other liquid additives are placed in a circle around the radius of the cylindrical part of the chamber from the central axis. Inside the working chamber, a rotating shaft with one to three tiers of inclined blades mounted on it and two to four fixed flow swirls is mounted to form an actively mixed fluidized bed of the product and circulation of hot air inside the layer. On the outside of the bottom, the working chamber is equipped with a device for receiving and supplying fresh low-pressure steam to the layer of the processed product, in the lower part the working chamber is equipped with an unloading lock.

The disadvantage of this device is the inability to use it in continuous mode.

Of the known analogues, the feed mixer is the closest in technical essence [A. No. 1611427 USSR, B01F 7/02, BI No. 45 07.12.90], which includes a housing with a cover with loading and unloading windows, two shafts, mixing working elements, a vertical partition, a drive including an electric motor, a belt drive, a gearbox and a gear .

The disadvantage of this device is the inability to introduce liquid components.

The objective of the utility model is to improve the quality of mixing the feed components during continuous operation of the mixer, to obtain a high-quality mixture with low humidity depending on a given recipe, ease of construction, low energy consumption of the mixture.

To perform this task, a system of nozzles is located under the housing cover along the axis of one feed mixer shaft from the side of the loading window, and chokes are installed in front of each nozzle to equalize the pressure and adjust their performance, while the device has a fluid supply system that includes two consumable containers with sensors for upper and lower liquid levels, valves, filters, hydrodynamic mixer, pressure reducing valve, flow meter and pressure gauge.

The proposed utility model is illustrated by the following drawings:

Figure 1 shows a General view of a device for introducing liquid mixtures into dry feed;

Figure 2 shows a section aa of figure 1;

Figure 3 shows a section bB of figure 2.

A device for introducing liquid mixtures into dry feed consists of: two containers 1 and 2 for liquid components with sensors for the upper 3 and lower 4 liquid levels, a pipeline 9 on which two valves 5, two filters 6, a hydrodynamic mixer 7 with a pump 8 for mixing of two liquids, a safety valve 10, a flow meter 11, a pressure gauge 12, and also nozzles 13, before which throttles 14 are installed on the pipe 9 to equalize the pressure and adjust the performance of the nozzles, while the nozzles 13 for supplying liquid additives Laga along the shaft 17 from the loading gate 20 to the dry components, which are mounted in the lid of the mixer 15; and also consists of a feed mixer, which includes a housing 16 with a cover 15, with a loading window 20 for dry components and an unloading window 19. Inside the housing 16, shafts 17 and 25 with mixing bodies 18 are mounted 18. A partition 24 is installed between the shafts in the mixing chamber , dividing the internal cavity of the mixer into two parts with the formation of a passage 26 between them on the opposite side from the windows and the end of the housing, which divides the mixer into two parts: the zone for introducing liquid additives and mixing them with the dry components of the mixture and the zone stirring. At the end of the shafts and in the direction of travel at the end walls, the turns of the screw of the reverse winding 21 are mounted; the device also has a drive 23 connected to the shafts via a gear 22.

A device for introducing liquid mixtures into dry feeds works as follows: two liquids from tanks 1 and 2 through filters 6 enter a hydrodynamic mixer 7, where they are mixed and pressurized to nozzles 13, which are located under the mixer cover, and the feed mixer is turned on and through the loading window 20 dry feed components arrive, which are carried away by the mixing bodies 18 located along the helix on the shaft 17 and move with simultaneous mixing and movement along the mixer body . Further, in the aisle zone 26, the fodder mass by the turns of the screw of the reverse winding 21 installed along the longitudinal axis of the shaft 17 is transferred to the shaft 25, changes the direction of movement to the opposite, where it mixes better, and it moves in the direction of the discharge window.

The proposed utility model will allow using the mixer in continuous operation, as well as improving the quality of finished products.
