Description

PRESS AUGER MASDER

The utility model relates to equipment of the oil and fat industry of the food industry and is designed to extract oil from oil-containing seeds, such as sunflower, rapeseed, etc., in workshops for the production of vegetable oil of low power and can operate as an independent unit or as part of a technological line

Known press M8-M1Sh final extraction of oil, consisting of a housing, a seed cylinder and a composite shaft located in it, made of four sections, each of which consists of halves interconnected by clamps, tightened by tie rods. Between the half sections laid knives. To regulate the thickness of the cake coming out of the press, the press is equipped with a cone mechanism (Machines and equipment for workshops and enterprises of small capacity for processing agricultural raw materials. Catalog, part I, sections 1-1U, Domestic and foreign equipment, - M ,: Informationgrotech, 1992 , s, 242) about

IPC: VZV with a cylinder and a sleeve with a die (Machines, equipment, devices and automation equipment for the processing branches of the agro-industrial complex, Catalog Addition - M ,: Informationgrotech, 1993, Sv23.G), The disadvantages of this design are the insufficient quality of the pressed oil from due to the non-uniformity of the gap between the fans and screws and burning of grain in narrower spaces, as well as low productivity due to the need for frequent reconfiguration of the value of the output gap. The closest in number of essential features and technical nature to the claimed utility model is a screw oil separating press, developed by Sibselmash software, containing a receiving hopper, a housing with a grain cylinder, a shaft located in it with screws and a washer fixed to the shaft, as well as an adjusting nut fixed to case in the area of the feeding auger, (Press screw oil separator ПШМ-250, Technical description and operating instructions, E213-OO.OO.OOOTO, PO Sibselmash, Novosibirsk, 1995). The disadvantages of this design are the insufficient quality of the pressed oil due to the unevenness of the gap between the fans and screws and the low productivity due to the need for frequent adjustments. The technical result achieved by the implementation of the claimed utility model is to improve the quality of the pressed oil and the performance of this press. This technical result is achieved due to the fact that the press is a screw oil press containing a receiving hopper, a housing with a grain cylinder, a core located in it shaft

with screws and a washer fixed to the shaft, as well as an adjusting nut, the adjusting nut is fixed to the press outlet and forms a gap for the cake to exit with the washer, and the shaft is made up of two parts, the drive and the screw, with the possibility of moving the screw part relative to the axis of the drive part of the shaft moreover, the connection of the two parts of the shaft is made by means of an axis on the screw part entering the hole of the drive part of the shaft with a gap, as well as by means of a slot on the drive part and a groove in the screw part of the shaft,

The shaft of the presented utility model is made of two parts. One of them is a drive, located on the drive side and fixed in the housing with the possibility of rotation around its axis.

The drive part of the shaft has a bore for an axis located in the center of the screw part of the shaft and entering this hole with a gap.

For coupling and the possibility of simultaneous rotation of these two parts of the shaft, they are also connected using a slot on the drive part and a groove made in the screw part of the shaft,

Such a connection allows the screw part to freely move the bottom relative to the axis of the drive part. When filling the screw space with oil-containing raw materials, as well as the space between the screw turns and the grain plates, compaction and pressing, the processed mass exerts unequal pressure on different parts of the shaft. This causes a complex displacement of the screw part of the shaft, as a result of which the raw material flows at different speeds in different directions and in As a result, the screw part of the shaft acquires a position.

characterized by the same gap between the shaft and the grain cylinder on their surface.

With this shaft design, the location on the housing of the adjusting nut at the outlet of the squeezing screw is optimal, where it forms and adjusts the clearance for the cake to exit the press with the washer.

The combination of the described essential features leads to the establishment of uniform pressures on the surface of the screws and grain plates, and therefore a uniform distribution of temperatures in the working space

Under such modes of extraction, the raw material does not overheat and does not burn, which positively affects the quality of the pressed

With the ability of the presented design to self-adjust to the optimal modes of oil extraction, there is no need to adjust the size of the output gap, which significantly increases the performance of the press.

Shigv depicts an oil-press screw press, a general view, a longitudinal section.

The oil screw press contains a receiving hopper I, housing 2 with a grain cylinder 3 made in the form of a set of plates adjacent to each other, a shaft located in it made of two parts, a drive 4 located on the side of the drive 5 and a screw b on which are fixed the feeding screw 7, the grinding screw 8 and the working pressing screw 9, and the washer 10 at the output of the shaft. At the outlet of the press, an adjusting nut II is located on the housing 2, which forms a gap with the washer 10

to exit the cake, the connection of the shaft parts is made by means of the axis 12 on the screw part b, which enters the hole of the drive part 4, and also using the slot 13 on the drive part 4 and the groove 14 in the screw part b of the shaft. The squeezed oil flows through the plates of the grain cylinder 3 into the substituted container

The oil screw press works as follows. The oil contains oil; it passes through the receiving hopper I into the housing 2, where it is captured by the turns of the feeding screw 7, which moves into the grinding screw 8 and the working pressing screw 9. In the region of the grinding screw 8 and the working pressing press 9, the raw material is crushed and heat treated under pressure in the space between, with coils of screws .8.9 and a grain cylinder 3, the implementation of the shaft located in the grain cylinder 3 of two parts, the drive 4, installed on the side of the drive 5, and the screw b, on which the screws 7.8 are located and 9 s the union of which is carried out by means of the axis 12 on the screw part b, which enters the hole of the drive part 4, and also using the slot 13 on the drive part 4 and the groove 14 in the screw part b of the shaft, makes it possible to self-adjust the position of the screw part b of the shaft, providing uniform clearance wood chips by the surfaces of the screws and the grain cylinder 3, and hence the uniform pressure on the oil-containing material. Heating of seeds occurs due to the work of internal friction forces in the seeds and friction of the mass of raw materials on the screws 7.8.9 and grain strips. In the area of the grinding screw 8 and especially the pressing screw 9, the pores and the intracellular structure of the seeds are intensively opened, which is accompanied by intensive oil separation . The process of oil separation occurs at a temperature of 80-120-C,

The pressure in the working space and, accordingly, the degree of squeezing the oil from the seeds is regulated by changing the gap between the washer 10 and the adjusting nut II by rotating it. The cake is extruded after separation of the oil from the raw material, and the oil flows through the plate of the grain cylinder 3 into the installed container .

The performance of this screw oil press is about 200-250 kg / h; with the dimensions of the inner diameter of the grain cylinder 3, in mm - 140-0.5; shaft rotation frequency - in rpm - 450,
