Description

The invention relates to devices for batch production of medicinal feed, as well as vitamin, thermolabile and mineral additives, and can be used on livestock and poultry farms.

The well-known "Method for the preparation of feed mixtures" (AS No. 1050152, 06/22/1983). Feed-drug mixture is prepared as follows. On a laboratory balance, the calculated dose of the drug and its equal portion of the filler, which is compound feed or crushed grain, are weighed. The resulting primary premix is poured into a small dose mixer, into which 10 kg of filler is loaded and mixed in a fluidized state for 3-4 minutes. The resulting working premix is poured into a large dose mixer, 40 kg of filler are loaded into it, and the components are mixed for 4-5 minutes. The mixture is unloaded in containers and fed to sick animals.

However, the large differences in the physicomechanical properties of the preparations (in the form of powder, tablets, granules, liquid) and the filler (compound feed, crushed grain), it is not possible to achieve a given level of uniformity of mixing (95-98%). It was revealed that “the homogeneity of mixing drugs with food is 93.5%” (Protocol No. 7-9-86 (2321010) of the state periodic tests of the installation of preparation of feed mixtures UKS-1 Ж 10.1.09.1986. State Agricultural Committee of the USSR Department for Mechanization and electrification). In addition, all the units of the installation work separately, openly, and the pouring of the processed mixture from one mixer to another is carried out manually, which is dangerous for the health of staff and possible loss of expensive drugs to the environment.

The well-known "Installation for the preparation of premixes and feed mixtures (Patent RU 2289974, C1, Ф23 No. 17/00, 06/21/2005). The installation includes two vertical mixers in communication with each other, equipped with mixing working bodies. The mixer for premixes is a centrifuge in the form of a truncated cone, its mixing working body looks like a scapula, and the mixer for feed mixtures is made in the form of a truncated cone with a screw guide and a screw blade. The premix mixer mixes the components poorly, since under the action of centrifugal forces they are pressed against the drum wall and rotate with it; the mixer for feed mixtures, made in the form of a truncated cone with a screw guide only transports the mass from the bottom up, and at large distances between the wall of the hull and the working body, intensive mixing does not occur. The above installation does not fully correspond to the declared purpose.

The well-known “Method for the preparation of feed mixtures” (RU 2635365 C1 11/13/2017 Bull.№32), including obtaining the primary premix by grinding and mixing in a grinder-mixer for primary premixes and preparing the premix by mixing the primary premix with filler in the mixer of feed mixtures in fluidized bed mode. It is known that the shredder-mixer (laboratory mill) does not provide fine grinding during the chaotic movement of the shredded mass (preparation and filler) where the principle of destruction of the material penetrates at low speeds.

The objective of the proposed invention is to create a method for the production of medicinal feed, providing high uniformity of mixing and the safety of staff.

The problem is achieved in that in a method for the production of medicinal feed, which includes receiving the primary premix by mixing and grinding the medicinal product and a portion of the filler in a laboratory mill for 50-60 with the preparation of the premix by co-grinding and mixing the resulting primary premix with a portion of the filler in the grinder -mixer for 60-70 s, while a continuous, steady supply of mixed components into the working area of the crusher-mixer with a rotating rotor they are due to continuous movement from the bottom-up of the mixture of components along the inner cylindrical and spherical surfaces of the chamber of the crusher-mixer, and from top to bottom - along the inner surfaces of two truncated cones located inside the crusher-mixer, communicated with small diameters with an angle of inclination of the forming cones to the horizontal plane α = 45 °, then mixing the resulting premix with a portion of the filler for 100-120 s in a ball mixer in the fluidized bed mode created by a blade fixed to the rotor shaft on lonno to the horizontal plane at an angle of 30 ° to obtain medicinal feed, and laboratory mill, mill-mixer and a ball mill for the production of medicinal feed sealingly interconnected.

The need to increase the uniformity of the mixture is caused by veterinary requirements (Alben - instructions, method of use // [Electronic resource]. URL: // www.zoozilla.org/drugs/drug/Alben): more effective drugs are used and their ratio with fillers increases - 1 : 500; 1: 1000; 1: 1500, which is presented in the table.

The multiplicity of mixing the drug Alben with feed

It is known that the most stressful and critical parts and components of airplanes, missiles, ships, etc. are currently made from composite materials (M. L. Kerber, V. M. Vinogradov, G. S. Golovkin “Polymer composite materials”; St. Petersburg. , 2008., 560 S.).

This is achieved by co-grinding the polymer composition to the smallest particles and simultaneously mixing, followed by heating and pressing, where intermolecular forces already act between the polymer components. The installation in the upper part of the crushing chamber of a structure of two truncated cones communicated with small diameters with an angle of inclination of the forming cones to the horizontal plane α = 45 ° is caused by the need for forced continuous supply of simultaneously crushed and mixed components into the grinding zone - between the ends of hammers and corrugated decks around its perimeter. The angle of inclination of the forming cones to the horizontal plane is selected according to the table (Recommendations on the use of machinery and equipment for preparing compound feeds on farms, Moscow Kolos 1977, p. 6) Slope angle of loose compound feeds and meal - 42 °. For reliable operation, the angle α is adopted with a margin of 45 °. The installation angle of the flat blade in the mixer at an angle of 30 ° to the horizontal plane is established experimentally. The essence of the invention is illustrated in the drawing - scheme "Method for the production of medicinal feed".

A method for the production of medicinal feed includes three stages of mixing and contains a laboratory mill 1 with a hinged lid 2 at the bottom of the cylindrical body 3, a scourge 5 is fixed on the drive shaft 4, in the lower part there is an unloading device 6 with a valve 7. For unloading the primary premix into the mixer crusher 8 in the upper part of its body 9 there is a receiving device 10 with a 1 G valve, and inside the body there is a structure of two truncated cones 12 communicated with small diameters, with an angle of inclination of the forming cones to the horizontal plane α = 45 °; in the lower part of the coaxial design of the truncated cones there is a rotor shaft 13 with disks 14 with rotary hammers 15 on the axes 16, and a corrugated deck 17 is installed in the lower part along the entire circumference of the rotor, an unloading device 18 with a valve 19 is located in the bottom of the crusher-mixer; includes a mixer 20, a truncated ball housing 21 with an upper receiving device 22 and a valve 23; at the bottom of the ball housing on the drive shaft 24 is fixed obliquely to a horizontal plane at an angle of 30 °, the blade 25, which cuts off a quarter of the capacity of the ball. An unloading device 26 with a valve 27 and a container 28 for packing medicinal feeds is installed at the bottom of the ball housing.

Method for the production of medicinal feed is carried out in the following sequence. Loading of all three nodes is performed with the drives turned off. In the laboratory mill 1 and the open hinged lid 2, in the cylindrical housing 3 with the shutter 7 closed, the rate of the drug and the filler is filled, the hinged lid is closed and the electric drive is turned on, the shaft 4 and the scourge 5 mounted on it are rotated, while the impact scourge grinds the preparation and filler by action for 50-60 seconds; the mixture (primary premix) with the open valve 7 through the discharge device 6 and the loading device 10 of the crusher-mixer 8 into the housing 9 with the open valve 11 is fed into the crusher-mixer; a portion (1.5-2 kg) of the filler is poured into it. When the upper valve 11 and the lower 19 are closed, the crusher-mixer is switched on. When the shaft of the rotor 13 is rotated, the disks 14 with hammers 15 on the axles 16 are rotated; the crushed components together and simultaneously fall into the gap between the ends of the hammers and the corrugations of the deck 17.

Within 60-70 seconds, the dose of the primary premix and filler are jointly ground to a fine grinding, moreover, by the method of denting one component into another, forming a uniform mass (premix) due to the molecular adhesion of the drug and filler. Forced continuous supply of the processed mass to the grinding zone is carried out using a design of two truncated cones 12.

It is known (Syrovatka V.I. “Machine technologies for preparing compound feeds on farms” M. 2010 Federal State Unitary Enterprise “Printing House” of the Russian Agricultural Academy p. 206-207) that when the rotor rotates in the center of the crusher - mixer, a vacuum is created from the axis, and pressure is applied to the deck. The neutral line runs 2/3 of the shaft axis. Therefore, the processed material under pressure rises along the vertical cylindrical wall and the spherical surface of the crusher body upward and under the influence of vacuum it is twisted downward along the axial line, where the upper truncated cone forms a flow and forcibly directs it to deck 17 to the grinding zone.

At the end of the grinding cycle (60-70 seconds), the electric drive of the crusher-mixer is turned off, the open valves 19 and 23, closed 27, through the discharge device of the crusher-mixer 18 and the upper receiving device 22 of the mixer 20, the premix is loaded into the ball housing 21. When the valve is closed 23, the shaft 24 and the flat blade 25 are driven. Upon completion of the mixing cycle (100-120 seconds) open valves 27 and 23 through the unloading device 26 therapeutic feed is unloaded in a container 28.

Laboratory grinder, crusher-mixer, ball mixer and container capacity are interconnected hermetically by nozzles.

Preparation of the secondary premix mixture by the method of simultaneous simultaneous grinding and mixing with the filler will allow to achieve uniformity (uniformity) of mixing the medicinal product with the filler 95%.
