Description

Technical Field

[0001] The utility model belongs to the technical field of supercritical extraction, and in particular relates to a pretreatment device for supercritical extraction. Background Art

[0002] Before supercritical extraction, the raw materials need to be ground to ensure the dissolution rate of the raw materials in the supercritical fluid during supercritical extraction. However, the existing pretreatment device for supercritical extraction has a complex structure and high maintenance cost, which increases the operating cost of supercritical extraction. Therefore, we propose a pretreatment device for supercritical extraction to solve the above problems and facilitate market promotion and application.

[0003] Chinese patent CN 217331814 U discloses a pretreatment device for supercritical extraction, including a processing component, a feed cover, a mounting plate, a drive motor, a magnetic suction component, a discharge door, an electric control cabinet and a button switch; the processing component and the drive motor are arranged so that the raw material enters the processing box through the feed cover, and the drive motor is powered on and operated by the button switch, the drive motor drives the first grinding roller to rotate, the first grinding roller drives the driven gear and the second grinding roller to rotate through the driving gear, the raw material is ground by the first grinding roller and the second grinding roller, so that the particle size of the raw material meets the requirements of supercritical extraction, the structure is simple, the maintenance cost is low, and the operating cost of supercritical extraction is reduced; the magnetic suction component is arranged so that when the raw material passes through the magnetic rod, the magnetic rod absorbs the magnetic impurities in the raw material, so as to achieve the purpose of removing the magnetic impurities in the raw material and improve the cleanliness of the raw material.

[0004] The inventors found that in this application, only the direct adsorption method of magnetic rods was used. Although it was able to remove magnetic impurities in the raw materials to a certain extent, the contact between the magnetic rods and the materials was limited, which could easily lead to some magnetic impurities not being adsorbed in time. At the same time, once too many impurities were adsorbed on the magnetic rods, it would easily lead to a decrease in the adsorption effect of the magnetic rods, resulting in a decrease in the efficiency of removing magnetic impurities.

[0005] Therefore, the existing structure and defects are studied and improved, and a pretreatment device for supercritical extraction is provided, in order to achieve a more practical purpose. Utility Model Content

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] Example 1, please refer to Figure 1 , Figure 2 and Figure 4A pretreatment device for supercritical extraction includes a treatment box 1, a feed hopper 11 is provided at the upper end of the treatment box 1, rotatable and symmetrically distributed grinding rollers 16 are provided in the treatment box 1, and a guide plate for feeding materials into the grinding rollers 16 is provided above the grinding rollers 16. A rotatable conveyor belt 2 is provided in the treatment box 1, one end of the conveyor belt 2 is located below the feed hopper 11, and a plurality of uniformly distributed and fixedly connected magnetic bars 26 are provided in the conveyor belt 2. A separation brush 18 for separating impurities from the conveyor belt 2 is provided on one side of the treatment box 1, and a collection box 12 for collecting impurities after separation is provided in the treatment box 1 below the separation brush 18.

[0033] The addition of the conveyor belt 2 can make the material evenly fed into the grinding roller 16, ensuring the grinding efficiency. At the same time, the combination of the conveyor belt 2 and the magnetic rod 26, the magnetism of the magnetic rod 26 can adsorb the magnetic impurities in the material, so that the impurities and the material are separated in time, and the cleanliness of the raw materials is improved; the addition of the separation brush 18 and the collection box 12 can use the separation brush 18 to separate the magnetic impurities from the conveyor belt 2 in time, and the collection box 12 collects them, effectively preventing excessive magnetic impurities and causing poor impurity separation efficiency.

[0034] See also Figure 3 , Figure 4 and Figure 5 In this embodiment, an elastic belt 25 is wrapped around the outside of the conveyor belt 2, and the two sides of the elastic belt 25 are fixedly connected to the two sides of the conveyor belt 2 respectively. A plurality of evenly distributed and through-type adjustment holes 24 are provided on both sides of the conveyor belt 2. A symmetrically distributed and synchronously rotatable adjustment disk 23 is provided in the conveyor belt 2 above the collecting box 12. The adjustment disk 23 is provided with a plurality of fixedly connected adjustment teeth 22 meshing with the adjustment holes 24.

The two ends of the fixing rods 27 are respectively located directly below the corresponding adjustment holes 24, and the adjustment teeth 22 push the fixing rods 27 to move downward.

[0035] The design of the elastic band 25, the adjustment disk 23, the adjustment hole 24, the adjustment tooth 22 and the fixed rod 27 can utilize the meshing between the adjustment hole 24 and the adjustment tooth 22 to make the conveyor belt 2 rotate while driving the adjustment disk 23 to rotate automatically, so that the adjustment teeth 22 can enter the corresponding adjustment holes 24 in sequence. As the adjustment teeth 22 are inserted into the adjustment holes 24, the adjustment teeth 22 can squeeze the fixed rod 27 to move downward, thereby driving the elastic band 25 to separate from the conveyor belt 2 through the fixed rod 27 and away from the magnetic rod 26, so that the magnetic impurities can automatically fall into the collection box 12 after losing the adsorption of the magnetic rod 26, thereby realizing the automatic separation of magnetic impurities. Combined with the separation brush 18, it can effectively improve the separation efficiency of magnetic impurities and conveyor belt 2 and reduce the residual magnetic impurities.

[0036] In this embodiment, a rotatably connected adjusting shaft is provided in the processing box 1, and the adjusting disk 23 is rotatably connected to the adjusting shaft.

[0037] See also Figure 5 In this embodiment, the separation brush 18 is located in the processing box 1 at one end of the feed hopper 11, and the separation brush 18 is arranged at the end of the conveyor belt 2. A through-type collecting groove is provided on one side of the processing box 1, and the collecting box 12 is slidably connected in the collecting groove.

[0038] See also Figure 5 In this embodiment, smoothing teeth 19 for smoothing materials are provided above the conveyor belt 2 , and the smoothing teeth 19 are fixedly connected to the inner wall of the processing box 1 .

[0039] The addition of the smoothing teeth 19 can make the material more evenly distributed on the conveyor belt 2, so that the magnetic impurities can be better adsorbed by the magnetic rods 26.

[0040] See also Figure 1 and Figure 2 In this embodiment, the conveyor belt 2 is provided with symmetrically distributed conveyor rollers 21 for driving the conveyor belt 2 to rotate. The conveyor rollers 21 are rotatably connected to the processing box 1. A first motor 14 is provided on one side of the processing box 1 for driving one of the conveyor rollers 21 to rotate.

[0041] See also Figure 1 and Figure 2 In this embodiment, a second motor 13 for driving the grinding roller 16 to rotate is provided on one side of the processing box 1.

[0042] See also Figure 5 In this embodiment, a discharge port 151 is provided at one side of the bottom of the processing box 1, a rotatable baffle plate 15 is provided at the discharge port 151, and an inclined discharge plate is provided below the grinding roller 16, and the discharge plate is connected to the discharge port 151.

[0043] When using this application:

[0044] (1) The material is fed into the processing box 1 through the feed hopper 11, and the material first falls onto the conveyor belt 2. As the conveyor belt 2 moves toward one end, when passing through the smoothing teeth 19, the smoothing teeth 19 can smooth the material on the conveyor belt 2, so that the material is more evenly distributed on the conveyor belt 2, and at the same time, the contact probability between the magnetic impurities and the magnetic rod 26 can be increased;

[0045] (2) When the material moves to one end along with the conveyor belt 2, the material automatically falls to the guide plate 17, is sent into the grinding roller 16 through the guide plate 17, is ground by the grinding roller 16, and is discharged through the discharge port 151;

[0046] (3) After the material is separated from the conveyor belt 2, the magnetic impurities are adsorbed by the magnetic rod 26 and are fixed on the conveyor belt 2. As the conveyor belt 2 moves to the top of the collection box 12, when it moves to the adjusting tooth 22, the adjusting tooth 22 can be inserted into the adjusting hole 24, and the fixing rod 27 below the adjusting hole 24 is squeezed, so that the fixing rod 27 drives the elastic belt 25 to separate from the conveyor belt 2. In this way, the gravity of the magnetic impurities can be greater than the adsorption force of the magnetic rod 26 by moving the magnetic impurities away from the magnetic rod 26, so that the magnetic impurities automatically fall into the collection box 12. When the adjusting tooth 22 is separated from the adjusting hole 24, the elastic force of the elastic belt 25 can make the elastic belt 25 automatically adhere to the outer surface of the conveyor belt 2, and at this time, the magnetic impurities have been separated;

[0047] (4) When the conveyor belt 2 moves to the separation brush 18, the separation brush 18 wipes the surface of the conveyor belt 2 again to make the surface of the conveyor belt 2 cleaner.
