Abstract

FIELD: oil-fat industry. SUBSTANCE: device for extraction of oil from oil-containing material uses a receiving hopper, batch-weigher, housing with a moulder chamber with an auger shaft positioned in it with formation of an annular gap for outlet of oil cake and a mechanism for adjusting the oil-cake outlet annular gap; the housing is a composite construction for adjustable longitudinal movement of the housing part with the moulder chamber, and the mechanism for adjusting the oil-cake outlet annular gap is formed by the movable part of the housing with the moulder chamber and replaceable ring member with taper surface installed in the moulder chamber in the zone of oil-cake outlet. EFFECT: enhanced reliability, durability, capacity at simultaneous reduction of material costs. 1 dwg

Description

 The invention relates to the oil industry, and in particular to the production of oil from an oil-containing material.

 The closest in technical essence from the known is the technical solution for a device for extracting oil from oil-containing material [1] including a receiving hopper, a dispenser, a housing with a grain chamber with a screw shaft located in it with the formation of an annular gap for the exit of the cake and the mechanism for regulating the annular gap to exit the cake.

The main disadvantages of the known device are the following:
low reliability of the device, since in the process of extracting oil from the oil-containing material, the annular gap adjustment mechanism for the cake exit and the thread in the grain chamber along which the annular ring adjustment mechanism moves for the cake exit are subject to intense wear and clogging, which leads to frequent device failure for extracting oil from the oil-containing material and significant efforts on the handles of the mechanism for regulating the annular gap for the exit of the cake, preventing the operational reg lation of the annular gap, and reduces the quality of processed material;
low quality of processing and productivity, since it is necessary to stop the device to regulate the annular gap for the cake exit, otherwise, in the process of regulating the ring gap for the cake exit, the ring clearance adjustment mechanism for the cake exit with the screw shaft can turn, the ring gap adjustment mechanism can be turned by the screw shaft to exit cake and operator injury;
significant material costs for repairs, as the heavy duty of the structural elements (the mechanism for regulating the annular gap for the exit of the cake, the thread of the housing of the grain chamber) leads to intense wear.

 The technical result of the invention is to increase reliability, durability, performance while reducing material costs.

 The specified technical result is achieved by the fact that in the proposed device for extracting oil from an oil-containing material, including a receiving hopper, a dispenser, a housing with a grain chamber with a screw shaft located in it with the formation of an annular gap for the exit of the cake, and a mechanism for regulating the annular gap for the exit of the cake, the housing is made integral with the possibility of adjustable longitudinal movement of the housing part with the grain chamber, and the mechanism for regulating the annular gap for the exit of the cake is formed by a movable h The case is equipped with a grain chamber and a removable annular element with a conical surface mounted in the grain chamber in the exit zone of the cake.

 This embodiment of the proposed device in comparison with the prototype will improve the reliability of the device for extracting oil from the oil-containing material, since from the most stressed section of the claimed device for extracting oil from the oil-containing material, the ring clearance regulation mechanism for the cake exit and the thread in the grain chamber along which the mechanism moves regulation of the annular gap for the exit of the cake, subject to intense wear and clogging is spaced apart by changing its design which will improve the quality of processing and productivity, since the regulation of the annular gap for the exit of the cake can be performed on a working device for extracting oil from the oil-containing material, and with the possible contact of the interchangeable element with the conical surface mounted on the screw shaft and the interchangeable ring element with the conical surface installed in the grain chamber, and placed in the exit zone of the cake, will not lead to a screw shaft turning the ring clearance adjustment mechanism to exit the cake, and injuring the operator, and also will significantly reduce the cost of material resources for repair, since with wear, a replaceable element with a tapered surface mounted on the auger shaft and a replaceable ring element with a tapered surface installed in the grain chamber are replaced, and not the mechanism for regulating the annular gap for the exit of the cake as a whole and the housing of the grain chamber.

 The drawing shows a device for extracting oil from an oil-containing material, a section.

 A device for extracting oil from an oil-containing material, contains a receiving hopper 1, a dispenser 2, a housing 3 with a grain chamber 4 with a screw shaft 5 located therein with the formation of an annular gap 6 for the exit of the cake, the mechanism for regulating the annular gap for the exit of the cake, which is formed by the execution of the housing 3 Composite with the possibility of adjustable longitudinal movement of the housing part 7 with the grain chamber 4 and a removable annular element 8 with a conical surface 9 installed in the grain chamber and placed in the exit zone of the cake. A part of the housing 7 with the grain chamber 4 is mounted on the part of the housing 10 on the key 11 with the possibility of axial movement, and the movement of the grain chamber 4 with the part of the housing 7 along the part of the housing 10 is performed by rotating the nut 12, and in the nut 12 and at the ends of the parts of the housing 7 and 10 Threads of the right and left directions or of one direction with different pitch are made.

 A device for extracting oil from an oil-containing material works as follows.

 The oil-containing material through the receiving hopper 1 and the dispenser 2 enters the housing 3 and is fed into the grain chamber 4 by the screw shaft 5, where oil is extracted from the oil-containing material, while the oil flows out through slots in the grain chamber, and the cake is discharged through the annular gap 6. Required the pressure level in the grain chamber 4 is set by changing the size of the annular gap 6 by moving part of the housing 7 with the grain chamber 4 and a removable ring element with a conical surface 8 by turning the nut 12.
