Description

The invention relates to agriculture and is intended mainly for use in personal subsidiary plots and farms.

Appointment of the device: the division of milk into fractions - cream and back in the summer-pasture period at non-electrified summer camps and in areas with unstable power supply.

A centrifugal milk separator is known, which includes a drum with a hermetically sealed partition forming a chamber for introducing a working fluid, or steam, or air into tubes with nozzles, while the stationary hollow axis has a pipeline for supplying the specified fluid, or steam, or air to the chamber (RU 2318608 C2, 11/12/2005, B04b 1/08, 9/06).

A gearless gas-driven milk separator is also known for separating suspensions and emulsions into fractions. This separator includes a separation drum and its drive. The latter consists of a typical gas turbine of a turbocharged diesel engine system. The energy of the exhaust gases comes from the exhaust manifold of the engine into the turbine nozzle and creates a torque on its blades. The turbine shaft is directly connected to the separator shaft by means of a coupling, due to which the turbine transmits rotation to the separation drum without any intermediary gears (RU 2350400 C2, 01.2006, B04b 9/06).

SUMMARY OF THE INVENTION

Separation of milk into fractions, achieved by rotating the separation drum, including a hermetically sealed partition, forming a chamber for introducing the working fluid, or steam, or air into the tubes with nozzles, while the stationary hollow axis has a pipeline for supplying the specified fluid, or steam, or air into the camera (prototype - patent RU 2318608 C2, 12.11.2005, B04b 1/08, 9/06).

Declared as the first prototype of the invention is a milk separator with a jet hydraulic drive. Hydraulic drive fluid for rotating the separator drum is supplied under pressure from the tractor hydraulic system via a high pressure hose into the cavity of the sealed chamber for injection into tubes with nozzles brought out of the sealed chamber at an angle of 90 ° in the horizontal plane. When operating pressure is reached, the drive fluid is ejected from the nozzles, creating a torque due to the action of reactive forces, which rotates the drum, in which milk is divided into fractions - cream and vice versa.

The disadvantage of the above separator is that to achieve the required speed of the separation drum, a high acceleration time is required, which is energy-intensive, reduces productivity and increases the duration of the primary processing of milk, which is not permissible for zootechnical reasons.

Declared as a second prototype of the invention is a milk separator with a gas turbine drive, which consists of a typical gas turbine of a turbocharged diesel engine. The energy of the exhaust gases comes from the exhaust manifold of the engine into the turbine nozzle and creates a torque on its blades. The turbine shaft is directly connected to the separator shaft by means of a coupling, due to which the turbine transmits rotation to the separation drum without any intermediary gears (RU 2350400 C2, 01.2006, B04b 9/06).

The disadvantage of the above separator is that to achieve the required speed of the separation drum, a high acceleration time is also required, which significantly increases the duration of the primary processing of milk and reduces productivity.

The objective of the present invention is to provide a high-performance separator for separating milk into fractions, which is structurally simple, requires minimal energy consumption and provides a minimum acceleration time until the drum reaches its rated speed when using a single energy source - a tractor.

The technical result of the invention consists in the possibility of rotation of the separator drum due to the use of a paired energy-driving device - a jet hydraulic drive and a gas turbine drive.

This technical result is achieved by the fact that in the proposed device, the separator drum with a sealed chamber and a reactive force generating mechanism is installed by means of a splined connection on the shaft of a gas turbine using compressed gas energy in its upper part, thus creating at the beginning of work during start-up and in the process work until the nominal speed is reached, the total torque for the rotation of the drum from the reactive force and from the gas turbine, which will reduce the acceleration time and ensure timely execution of primary processing of milk in the stream at all its technological stages in accordance with zootechnical requirements, as well as reduce energy costs in the initial period of operation of the separator.

The described device is illustrated in the drawing.

Figure 1 schematically shows a longitudinal section of a separator. The centrifugal milk separator includes a drum 1, containing a cover 2 and a base 3, equipped with a plate holder 4 with a package of plates 5 and a separating plate 6, a receiving and output device for milk and its fractions, including a tube 7 for inputting milk, a pressure disk 8 of the output of cream and pressure disk 9 output back. The cream is discharged into the receiving chamber through the nozzle 10, the return enters the receiving chamber through the nozzle 11. Below the base of the drum through a sealed partition 12, a sealed chamber 13 is formed for introducing the working fluid, or steam, or air into the tubes with nozzles 14 (Fig. 2) while the stationary part of the supporting device has a pipe 15 for supplying the specified liquid, or steam, or air into the chamber 13 through an internal hole in the upper part of the shaft 17. The lower part of the separator drum with a sealed chamber 13 is installed by ohm splined connection 16 on the shaft 17 of the gas turbine 18 with a device 19 for entry and exit of compressed gas 20.

The feed of milk into the drum for separation is carried out using a flexible pipe 21, the uniformity of supply is regulated by the float device 22.

The separator works as follows.

Through a flexible pipe 20, milk is supplied to the float device 21 of the receiving device to ensure a uniform flow of milk into the inner cavity of the drum 1.

Milk through the tube 7 is introduced into the cavity of the plate holder 4 and from it into the plate package 5, in which, during rotation, it is divided into cream and vice versa. In the inner cavity of the drum with the help of the separating plate 6, two flows are formed - the cream discharged from the drum using the pressure disk 8, and the return discharged using the pressure disk 9. The cream removed from the drum enters the receiving chamber through the pipe 10 and along the outlet inclined channel served in a container for cream, the return allocated from the drum enters the receiving chamber through the pipe 11 and is fed into the container for backflow through the outlet inclined channel. The design of the receiving and output device and the principle of dividing milk into fractions does not differ from existing standard separators.

The advantage of this milk separator with a drum, an airtight chamber and a mechanism for generating reactive forces connected structurally by means of a splined connection to the shaft of a gas turbine using compressed gas energy in its upper part is the formation of the total torque especially necessary at the beginning of operation during start-up and during the process work until the nominal speed of the drum from the reactive force and from the gas turbine is reached to reduce the acceleration time and ensure timely complements preprocessing milk flow at all process stages in accordance with the zootechnical requirements and cost reduction of energy during the initial period of operation of the separator and increase its productivity.
