[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0020] Example 1

[0021] See attached Figure 1-Figure 2 As shown, the utility model provides a spiral conveying extraction device, including a vertical spiral conveyor 1 and an inclined spiral conveyor 2 arranged at an angle of 45°, which can reduce the height and floor space of the equipment. Among them, the vertical spiral conveyor 1 includes a feed barrel 1a and a raw material inlet arranged at its top, and the raw material enters the feed barrel 1a through the raw material inlet. The top of the feed barrel 1a is fixedly installed with a first reduction motor 1c, and the output end of the first reduction motor 1c is fixedly connected to the vertical spiral propeller 1d in the feed barrel 1a, and the top of the feed barrel 1a is provided with an extraction liquid outlet 1e; the inclined spiral conveyor 2 includes an extraction barrel 2a connected to the bottom of the feed barrel 1a, the top of the extraction barrel 2a is fixedly installed with a second reduction motor 2b, and the output end of the second reduction motor 2b is fixedly connected to the inclined spiral propeller 2c rotatably arranged in the extraction barrel 2a, and the top of the extraction barrel 2a is provided with a solvent inlet 2d.

[0022] During operation, the raw material enters the feed barrel 1a through the raw material inlet, and under the action of the first reduction motor 1c, the vertical screw propeller 1d is driven to continuously transport the raw material through the feed barrel 1a to the extraction barrel 2a. At the same time, the solvent (extraction liquid) enters the extraction barrel 2a through the solvent inlet 2d, and under the drive of the second reduction motor 2b, the extraction liquid and the raw material are fully immersed, so that the extraction liquid and the raw material are continuously countercurrently extracted in the extraction barrel 2a.

[0023] In the process of continuous extraction of raw materials and extracting liquid, the conveying speed of the vertical screw conveyor 1 is controlled by the first reduction motor 1c, so that the vertical screw conveyor 1 pushes the raw materials into the extraction cylinder 2a at a uniform speed, and performs reverse extraction with the extracting liquid in the extraction cylinder 2a. The extracted raw materials, under the action of the second reduction motor 2b, drive the oblique screw propeller 2c to discharge the raw material residue from the residue outlet 6 at the top of the extraction cylinder 2a, and the discharged raw material residue collects the residual liquid under the action of the squeezer. In addition, a drain port 7 is also provided at the bottom of the extraction cylinder 2a, which can be used to collect the remaining liquid inside the extraction cylinder 2a or to clean the residue. During cleaning, cleaning water is introduced through the feed port on the feed cylinder 1a and the solvent inlet 2d respectively to clean the inside of the feed cylinder 1a and the extraction cylinder 2a, and the residual liquid after cleaning is discharged together through the drain port 7, which is convenient and efficient to clean.

[0024] like Figure 1As shown, in order to prevent the inclined screw propeller 2c from bringing out the solvent or the extract through the raw material slag during the discharge of the raw material slag from the slag outlet 6 at the top of the extraction cylinder 2a, and in order to quickly collect the extract in the extraction cylinder 2a from the extract outlet 1e, the vertical screw propeller 1d and the inclined screw propeller 2c include a transmission shaft 8 fixedly connected to the output ends of the first reduction motor 1c and the second reduction motor 2b respectively, and the transmission shaft 8 is provided with a spiral hole plate 9, and the spiral blade surface of the spiral hole plate 9 is provided with an axial through hole. The spiral hole plate 9 on the inclined screw propeller 2c can filter the liquid in the process of the raw material slag being discharged from the slag outlet 6 at the top of the extraction cylinder 2a; the vertical screw propeller 1d can make the extract in the extraction cylinder 2a smoothly pass through the spiral hole plate 9 and be collected from the extract outlet 1e.

[0025] It should be noted that the vertical height of the solvent inlet 2d is greater than the height of the extraction liquid outlet 1e, so that the liquid phase can flow naturally.

[0026] Example 2

[0027] In order to improve the extraction efficiency of the raw material and the solvent in the extraction cylinder 2a. The outer wall of the feed cylinder 1a is provided with a first jacket 3, the top of the first jacket 3 is provided with a first steam inlet pipe 3a connected to the interior thereof, and the bottom of the first jacket 3 is provided with a first steam condensate outlet 3b connected to the interior thereof; the outer wall of the extraction cylinder 2a is provided with a second jacket 4, the top of the second jacket 4 is provided with a second steam inlet pipe 4a connected to the interior thereof, and the bottom of the second jacket 4 is provided with a second steam condensate outlet 4b connected to the interior thereof.

[0028] The first jacket 3 and the second jacket 4 respectively form a heating chamber with the outer wall of the feed cylinder 1a and the extraction cylinder 2a. Steam enters the jacket through the first steam inlet pipe 3a and / or the second steam inlet pipe 4a, and the steam changes from steam to liquid in the first jacket 3 and the second jacket 4 to release heat. The released heat can heat the raw materials or solvents in the feed cylinder 1a and the extraction cylinder 2a by heat transfer, thereby improving the extraction effect in the reverse extraction process. The converted liquid is discharged through the first steam condensate outlet 3b and the second steam condensate outlet 4b respectively.

[0029] like Figure 2 As shown, in order to prevent the steam from being not completely liquefied during the liquefaction process, the present application provides at least one retention chamber 5 on the inner wall of the first steam inlet pipe 3a and / or the second steam inlet pipe 4a, and the retention chamber 5 can delay the time for the steam to reach the first steam condensate outlet 3b and the second steam condensate outlet 4b, so that the steam can have enough time to liquefy and release heat in the first jacket 3 and the second jacket 4.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
