Description

The utility model relates to equipment of the oil and fat industry and can be used to extract oil from plant material.

Famous oil press FP (V. Maslikov. Technological equipment for the production of vegetable oils. M .. Food industry, -1974. P. 253) consisting of a bed, a horizontal grain drum consisting of four sections, inside of which there is a screw shaft with a set of pressing turns, cone-type adjusting mechanism with a movable cone, a power regulator made in the form of a vertical single-turn screw located in a vertical supply chute above the receiving turn of the screw shaft and drive.

The disadvantages of this press are: the need for special preparation of the pulp, which requires special life, as well as the complexity of the design of the adjusting mechanism of the cone type with a movable cone.

The closest known one is the AN-88H screw press extruder (Anderson's Catalog of the American company, 1991.) consisting of a bed horizontally located and interconnected with a grain drum and an extruder part with a steam supply system, inside from 11 to 1/06

Screw extruder

For which there is a pushek shaft with a set of extruder and pressing coils, dies for granulating the cake and located on the end of the fan drum and drive.

The disadvantages of the prototype is that the output of the squeezed material goes through a matrix with holes whose sizes and, accordingly, the pressure in the press cannot be changed on a working press.

The purpose of the utility model is to ensure the processing of oilseed material without special preparation with the ability to control the moisture-thermal mode of operation of the press, and the level of pressing pressure.

This goal is achieved by the fact that the screw press extruder includes interconnected grain cylinder with an adjusting device and an extruder part inside of which there is a screw shaft with extruder and pressure coils. The screw shaft through the coupling is connected to the drive. The extruder part consists of three collets connected in series, the first of which is equipped with a bearing assembly and a loading funnel, and the second and third are equipped with a water and steam supply system. The adjusting device is made in the form of a cone mechanism consisting of a cone located on the screw shaft and a movable sleeve with the possibility of movement in the axial direction using a screw mechanism.

The extruder part with a water and steam supply system allows grinding and moisture-heat treatment of the material directly in the press, eliminating a number of additional equipment. An adjusting device made in the form of a fixed cone and a movable sleeve simplifies the design of the device itself, and with the help of a changing gap to regulate the pressing pressure affecting the degree of compression of the pulp.

set out in the formula of the utility model allows you to achieve the desired result, namely to ensure the processing of oilseed material without special preparation with the ability to regulate the moisture-thermal mode of operation of the press, and the level of pressing pressure.

Figure 1 shows a schematic kinematic diagram of a screw press-extruder.

The screw press extruder consists of two main assembly units.

The first assembly unit is a drive that includes an electric motor 1, a V-belt drive 2, a gearbox 3.

The second assembly unit is a press unit. It has the following design: a shaft 4, on which a cone 5, a set of pressing coils b, and a set of extruder coils 7; the shaft is supported by a front bearing assembly 8, a rear bearing assembly 9, including a thrust bearing 10; the shaft 4 passes through the szkrudernoy chamber 11 with a loading funnel 12, as well as with knives 13 fixed therein, and a grain cylinder 14, at the output of which a movable sleeve 15 is connected to the screw mechanism 16.

The drive and the press unit are connected by a clutch 17.

Screw press extruder operates as follows. The shaft 4 of the press unit, rotating due to the transmission of torque by the clutch 17 from the electric motor 1 through the V-belt drive 2 and the gearbox 3, transports the oil material supplied through the feed funnel 12, the extruder chamber 11 and the grain cylinder 14. Oilseeds moving along the extruder turns 7 in the extruder the chamber 11 is subjected to grinding due to the action of shearing forces arising in the gap between the face of the rotating coil 7 and several stationary knives 13 installed in the plane perpendicular to the axis of the shaft 4 , and located evenly along the perimeter, meter of the extruder chamber. If it is necessary to heat and heat treat the material, the design of the extruder chamber 11 has moisture and steam inlets through special knives 13. After grinding, the oily material is fed into the fan cylinder 14 consisting of two successive stages, characterized by a reduced gap between the grain plates in the second stage, where the oil is squeezed due to pressure created by a consistent decrease in the free volume of the turns and by increasing the internal diameter of the pressing turns 6, as well as by controlled change the annular gap between the cone 5 and the movable sleeve 15 which is moved by a screw mechanism 16 by rotating hand wheel fastened to a screw mechanism. The pressed press oil leaves the pressing zone through the gaps between the grain plates of the grain cylinder 14, and the pressed material into the gap between the cone 5 and the movable sleeve 15. The front and rear bearing bearings 8 and 9 fix the horizontal position of the shaft 4. To prevent axial displacement of the shaft behind due to the reaction force of the material to its pressing, a thrust bearing 10 is installed in the design of the press assembly. The design of the coupling 17 compensates for possible misalignment of the shafts of the output shaft of the gearbox 3 and the shaft of the press assembly 4, and is a mechanical overload protection.
