Abstract

The utility model relates to a round extruder used in oil mill, in particular to a round extruder used in oil mill for screw pushing extrusion, pertaining to the press suitable for special use. The utility model consists of a round extruder body, anomalous grooves, a key groove and an oil groove; 8 anomalous grooves are evenly distributed in the inner hole of the round extruder body and form convex and concave points. The round extruder continuously compresses the oil material through that when the squeeze screw of the oil mill rotates in the round extruder of the oil mill, the space capacity formed by the squeeze screw and the round extruder is reduced gradually; then the oil is extruded out from the oil material and flows out along the oil groove so as to finish the squeezing. The round extruder can make the screw oil mill carry out three-class squeezing in the squeezing chamber, solving the problem that the prior oil mill needs to repeatedly squeeze the material so as to extrude the oil out from the oil material. The utility model makes the whole oil mill have small volume and low energy consumption.

Description

Circle row

Technical field:

The circle row who uses in a kind of oil press, the circle row who uses in particularly a kind of screw oil expeller belongs to the forcing press field that is specially adapted for specific use.

Background technology:

The circle row of screw oil expeller, it is the vital part of forming the oil extruder thorax, it directly influences the oil yield of oil press and the height of dry cake residual oil rate, the circle row that oil press adopted who uses on the existing market and sell, because the influence of factors such as the planform of its endoporus and size, make that the interior gun pressure power of oil press is little, the thorax wall can not form pressed zone well after the spiral shell outer surface cooperates with pressing, make that oil plant extruding force in expressing process is not enough, must squeeze repeatedly raw material, therefore, existing oil press not only oil yield is low, the dry cake residual oil rate height yields poorly, and energy consumption is big.

Summary of the invention:

Technical problem to be solved in the utility model is: provide a kind of can making to press spiral shell three grades of squeezings of implementation in pressing thorax, improve the interior gun pressure power of oil press, make thorax wall and press for extracting juice spiral shell outer surface form a plurality of diminishing pressed zone, and only need raw material is carried out disposable squeezing, just oil can be drained from oil plant, and make machine volume little, energy savings, the circle row of screw oil expeller stably of turning round.

The technical scheme in the invention for solving the above technical problem is: this circle row is made up of circle row main body 1, special-shaped groove 6 and oil groove 7, eight special-shaped grooves 6 are on the inner hole wall of circle row main body 1, have a keyway 8 on the outer surface of circle row main body 1, it is characterized in that: be shaped on concave point 4 and salient point 5 on the special-shaped groove 6, the two ends of circle row main body 1 are shaped on boss 2,3 respectively, have oil groove 7 on the boss 2, spacing between the boss 2,3 is 18mm, diameter between the concave point 4 is 85mm, and the diameter between the salient point 5 is 81.5mm.

The utility model compared with prior art and has following beneficial effect:

1. this circle row is diminishing with the sectional area that presses the space that spiral shell forms in pressing thorax, makes the material indusium gradually reduce, and pushes away press for extracting juice spiral shells at different levels by force, and form multistage squeezing.

2. because the interior space of thorax sectional area diminishes gradually, make that the material embryo of the interior front of thorax is faster than the material embryo translational speed of back, by its speed difference, improved the pressure of thorax in the oil press, and, improved pressing temperature by the phase mutual friction between the oil plant.

3. use this circle to come under the volume situation of thorax in the same oil press, can make oil plant carry out three grades of squeezings, gun pressure power in increasing increases oil yield, reduces dry cake residual oil rate.

4. use this circle row that machine volume is diminished, solved the rural area, particularly the mountain area oil plant relatively disperses, and oil plant is not limit the problem that can process at any time.

Description of drawings:

Accompanying drawing 1 is circle row's front view;

Accompanying drawing 2 is circle row's right view.

Specific embodiments:

This circle row is made up of circle row main body 1, special-shaped groove 6 and oil groove 7, and special-shaped groove 6 is on the inner hole wall of circle row main body 1, and the outer surface of circle row main body 1 has a keyway 8, and circle row main body 1 is contained in its press for extracting juice cage, and fixes in radial direction by keyway 8.The two ends of circle row main body 1 are shaped on boss 2 and 3 respectively, have oil groove 7 on the boss 2, and eight special-shaped grooves 6 on the endoporus of circle row main body 1 are arc surface, are formed with concave point 4 and salient point 5 on the arc surface.When the press for extracting juice spiral shell of oil press rotates in circle row endoporus, because the space that circle row and press for extracting juice spiral shell form holds trifoliate orange and diminishes gradually, thereby carry out compression to oil plant, owing on the arc surface concave point 4 and salient point 5 are arranged, oil plant can inside stir, and oil plant is owing to be compressed, thereby the grease in the oil plant is squeezed out, and along 7 outflows of the oil groove on the boss 2, and finish expressing process.

Make oil press complete machine size little in order to guarantee that this circle row can reach, the press for extracting juice breech pressure is big, realize the purpose of three grades of squeezings, the optimal way of this circle row part-structure size is: the external diameter of circle row body 1 is 118mm, spacing between the boss 2 and 3 is 18mm, diameter between the concave point 4 is 85mm, and the diameter between the salient point 5 is 81.5mm.

Claims

A kind of circle row, it is made up of circle row main body 1, special-shaped groove 6 and oil groove 7, have a keyway 8 on the outer surface of circle row main body 1, it is characterized in that: be shaped on eight special-shaped grooves 6 on the inner hole wall of circle row main body 1, be shaped on concave point 4 and salient point 5 on the special-shaped groove 6, the two ends of circle row main body 1 are shaped on boss 2 and 3 respectively, have oil groove 7 on the boss 2, spacing between the boss 2 and 3 is 18mm, and the diameter between the concave point 4 is 85mm, and the diameter between the salient point 5 is 81.5mm.
