Description

Technical Field

[0001] This utility model belongs to the field of oil press technology, and in particular relates to a double-screw oil press that is easy to collect. Background Technology

[0002] The pressing of vegetable oilseeds can be divided into hot pressing and cold pressing. Crude oil produced by hot pressing undergoes solvent extraction and refining, resulting in solvent residue and the loss of most fat-soluble vitamins. Oil produced by cold pressing, on the other hand, retains its all-natural properties and preserves the physiologically active substances in the oil.

[0003] The oil presses currently in use still have some problems when pressing raw materials. Because the double helical rod inside the oil press is quite long, there are many oil outlets at the bottom of the oil press, so a long oil receiving device is required, which makes the oil receiving work troublesome. In addition, the filter screen used to separate crude oil and oil residue is prone to clogging after long-term use. Currently, the filter screen is fixed to the oil outlet of the oil press with screws, which makes disassembly and assembly cumbersome and brings trouble to cleaning the filter screen. Utility Model Content

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a double-screw oil press that facilitates oil collection, such as... Figure 1-4 As shown, the device includes a housing 1, a feed chute 2 mounted on the top of the housing 1, two sets of rollers 3 rotatably mounted on the inner wall of the housing 1, and spiral blades 4 mounted on the outer wall of the rollers 3. The spiral blades 4 mounted on the surface of the rollers 3 are staggered. A motor 5 is mounted on the outer wall of the housing 1, and the output shaft of the motor 5 is connected to the central shaft of the rollers 3. An oil outlet plate 6 is mounted on the lower side of the housing 1, and a filter screen 7 is mounted on the upper inner side of the oil outlet plate 6. The filter screen 7 is in contact with the edge of the spiral blades 4. The interior of the oil outlet plate 6 is hollow, and an oil collection trough 8 is mounted at the bottom center. A discharge chute 9 is opened on the lower right side of the housing 1. The housing 1 is supported and fixed by two sets of brackets 10, wherein the right bracket 10 is L-shaped and the surface... The device includes a collection box 11. When in use, the raw material enters the housing 1 through the feed chute 2. At this time, the motor 5 is started, and the output shaft of the motor 5 drives the two sets of rollers 3 to rotate. The spiral blades 4 on the surface of the two sets of rollers 3 squeeze the raw material. The squeezed crude oil falls from the mesh of the filter screen 7 into the oil outlet plate 6 and flows out from the oil collection trough 8 at the center of the oil outlet plate 6. The oil residue is pushed by the spiral blades 4 and discharged from the discharge chute 9 into the collection box 11. The device can separate and collect crude oil and oil residue separately through the oil outlet plate 6 and the collection box 11, thereby effectively improving the convenience of oil pressing. By setting the oil collection trough 8, crude oil can be discharged from a single oil outlet point, thereby improving the convenience of crude oil collection.

[0021] The oil outlet plate 6 is arc-shaped, and sliders 12 are installed on both the left and right sides of the oil outlet plate 6. The lower side of the housing 1 is provided with a sliding groove that matches the sliders 12. The oil outlet plate 6 is slidably connected to the housing 1 through the sliders 12. A pull block 13 is installed at the front end of the oil outlet plate 6. With the sliders 12, the oil outlet plate 6 is installed below the housing 1. The pull block 13 can be pulled to the left to pull the oil outlet plate 6 outward. This setting can improve the convenience of disassembling and assembling the oil outlet plate 6, thereby facilitating the cleaning of the inside of the oil outlet plate 6.

[0022] The bottom of the inner wall of the oil outlet plate 6 is inclined to the oil collection trough 8. By setting the inner wall of the oil outlet plate 6 to be inclined, crude oil residue in the inner wall of the oil outlet plate 6 can be avoided, thereby ensuring normal oil output.

[0023] A positioning block 14 is installed on the inner wall of the oil outlet plate 6. The filter screen 7 is placed above the positioning block 14. By setting the positioning block 14, the filter screen 7 is positioned by the positioning block 14. The positioning block 14 limits and fixes the filter screen 7. This method can improve the convenience of disassembling and cleaning the filter screen 7.

[0024] A heating device 15 is installed on the right outer wall of the housing 1. The heating port of the heating device 15 is connected to a resistance wire 16. The roller body 3 is set as a hollow structure and has a through groove at the right end. The resistance wire 16 is located inside the roller body 3 and does not contact the roller body 3. By setting the heating device 15, the heating device 15 heats the roller body 3 through the resistance wire 16. The oil yield of the raw material can be improved by heating.

[0025] A limiting block 17 is installed on the inner wall of the collection box 11. A gauze frame 18 is placed above the limiting block 17. A through groove is opened on the lower right side of the collection box 11 and a threaded cover 19 is installed on the outside. With the gauze frame 18 installed, the oil residue also contains some crude oil. When the oil residue falls into the collection box 11, the crude oil in the oil residue will fall from the surface of the gauze frame 18 into the bottom of the collection box 11. After the oil pressing is completed, the threaded cover 19 can be opened to draw out the crude oil.
