Description

one

The invention relates to the meat industry, namely to devices for separating meat from bone.

The purpose of the invention is to reduce metal consumption and simplify the design.

Fig, 1 shows a schematic press, a general view; Fig, 2 - the same, side view in section; in fig. 3 - loading chamber and press chamber, in section.

The horizontal hydraulic press for separating the bone from the bone comprises a frame 1, a support frame 2 mounted on a cantilever, a cylindrical pressing chamber 3 j loading chamber 4, a hydraulic drive 5. The power frame 2 is made in the form of a tubular body, and a pressing chamber 3 and loading chamber 4 are located inside the body in its cantilever part, and the opposite end of the tubular body is mounted by the cylinder 6 of the hydraulic actuator 5. On the cylinder 6 there is a device for fixing the pipe body against rotation and axial movement The displacement is a filling valve 7. Inside the cantilever part of the tubular body, there is also a support ring 8, a damper 9 driven by a hydraulic cylinder 10 with a set of concentric end filter rings 11. In addition, the press contains a lift 12, a chopper 13 with a hopper 14, nozzles 15 and 16 for removing pressed molded mass . Frame 1 is an all-welded construction, the vertical and horizontal walls of which form four compartments. The upper left and lower right compartments are hydraulic tanks A and B. In the holes two vertical CTBHOi of the lower left compartment B there is a tubular body. An electric motor 17 with a pump installation 18 immersed in a hydraulic tank B is strengthened on the horizontal wall of compartment G. The pressing chamber 3 consists of a holder 19 and a set of radial filter rings 20. Inside the cylinder 6 of the hydraulic drive 5 there is a piston 21 with a piston cavity E. Rod 22 piston 21 is guided in sleeves 23 and 24 mounted in a housing. In the screw cap 25 of cylinder 6, the piston rod 26 of the hydraulic accelerator cylinder 26 is replaced;

it in the cavity D of the piston 21 and having a rod cavity P. Fixing the body against rotation and axial movement is carried out using a sleeve 28 concentrically mounted on the filling valve 7 and in the hole of the horizontal wall of the bed 1. The sleeve 28 is sealed with rings 29 and 30. At the end of the rod 22, a pressing head 31 with an end face m, having a set of concentric end filter rings 32, is fixed. A valve 9 having an opening I is driven by a hydraulic cylinder 10 connected to the main lines and an oil pipe. The hydraulic cylinder 10 is mounted on the housing with the help of studs 33 and nuts 34. The burt L is the stop for the piston 21. With the extreme forward position of the head 31, the end face M of the head coincides with the plane H of the valve 9.

Horizontal hydraulic press for separating bone from bone

25 works as follows.

When supplying the working fluid from the pumping unit 18 to the cavity D of the accelerating cylinder, the piston 21 quickly moves to the left, the head 31 captures 4 portions of crushed raw material from the loading chamber and moves it into the pressing chamber 3. At the same time, the filling valve 7 opens at the expense of the discharge that has occurred in the cavity E, and the working fluid from the tank A enters the cavity E under the action of atmospheric pressure, and then the working fluid is pumped from the tank B via the hydraulic distributor 18 to the cavity E. 6, as a result of which the pressure builds up in it, the filling valve 7 is closed, and

45 working stroke pressing. Wherein

head 31 s winters in the chamber volume zavy.wfTOM 3 portion of crushed m juice raw material and multiplies in it high pressure (up to 80 MPa),

50 as a result of which the separation of maca from the bone occurs. The separated sleep mass in the pasty state is pushed out through the filter rings 11, 17 and 32 and is discharged into

from the trolley through the pipes 15 and 16. When pressed, the piston 21 stops, the working fluid is pumped by the pump unit 18 to the hydraulic line G of the hydraulic cylinder 10, Za30

the slider 9 opens, its opening and is installed against chamber 3 The working fluid is again fed into the cavity D of the accelerating cylinder, the piston 21 is quickly moved to the left, and the bone residue is pushed out through the opening 9 of the valve 9 and the opening K of the housing into the trolley. At the end of the push-in process, the piston 21 stops, abutting against the hull shoulder of the body, which ensures the extreme front position of the end face M of the head 31 flush with the cavity H of the valve 9, the working fluid is fed into the main line O. of the hydraulic cylinder 10, and the valve 9 closes. fluid is supplied to the cavity P of the accelerating cylinder, as well as to the main line P of the filling valve 7. The valve 7 opens and the liquid from the cavity E of the cylinder 6 is squeezed out into the tank A. A smooth return of the piston 21 to its initial position occurs, and a new portion of the crushed fine raw material enters the empty space of the loading chamber 4. Then the cycle is repeated.

The implementation of the proposed design allows for ease of maintenance of the press and sanitization, rational placement

the elements of the press inside the tubular body, as well as the simpler implementation of a number of assemblies, reduce the metal structure, simplify its design and preserve the necessary rigidity, which ensures reliable operation of the press to separate the bone from the bone.
