Description

Technical Field

[0001] The invention belongs to the technical field of sesame oil processing equipment, in particular to a sesame oil stirring and oil-extracting device based on a water substitution method. Background Art

[0002] The process of stirring sesame oil to extract oil by the water substitution method is mainly based on the hydrophilicity of protein and the hydrophobicity of oil. The colloidal state of the oil is destroyed by adding water to achieve oil-water separation. The main principle is to first grind the sesame seeds into a paste, add hot water to the sesame paste, and then use a stirring stick to stir it evenly so that the oil layer is suspended on the upper layer of the liquid. The upper oil layer can then be taken out.

[0003] After the existing sesame oil stirring device stirs the sesame oil to produce an oil layer and collects it, the residual crude oil at the bottom will fall down for filtration, so that the internal sesame residue is filtered and blocked at the top. However, since the material is filtered in one direction when it is discharged, a large amount of sesame residue accumulates and blocks the filter screen, affecting the filtration of the crude oil. Therefore, it needs to be improved. Summary of the Invention

[0035] Through the operation of the driving mechanism 9, the end of the driving mechanism 9 can drive the two rectangular frames 803 to move back and forth in opposite directions, so that the linkage arm 804 is deflected, and then the lifting assembly 7 can be driven as a whole to push the filter frame 5 upward, or downward, the filter frame 5 is lowered by its own gravity, so that the sesame residue on the top of the filter frame 5 is evenly distributed by shaking it up and down.

[0036] like Figure 2 As shown, the stirring mechanism 2 includes a stirring drum 201, a stirring assembly 202 and a feeding pipe 203;

[0037] The mixing drum 201 is fixedly installed at the top of the inner cavity of the box body 1 , the stirring assembly 202 is arranged in the middle of the inner cavity of the mixing drum 201 , and the feeding pipe 203 is fixedly connected to the middle of the top end of the box body 1 .

[0038] The above solution is adopted: by providing a stirring component 202, when the operator starts the stirring component 202, the sesame seeds and water inside the stirring drum 201 can be stirred to produce sesame oil.

[0039] like Figure 2 As shown, the oil outlet mechanism 4 includes a hydraulic cylinder 401, a movable torque tube 402, a connecting torque tube 403 and an oil storage tank 404;

[0040] The hydraulic cylinder 401 is arranged inside one side of the mixing drum 201, the movable rectangular tube 402 is fixedly installed at the output end of the hydraulic cylinder 401, the connecting rectangular tube 403 is arranged in the inner cavity of the box body 1, and the connecting rectangular tube 403 is located at the bottom end of the movable rectangular tube 402, and the oil storage tank 404 is arranged on one side of the box body 1 and is located below the outer side of the connecting rectangular tube 403.

[0042] like Figure 1 and Figure 4 As shown, a discharge pipe 6 is fixedly connected to the bottom of one side of the box body 1 , an observation window 12 is fixedly installed in the middle of the front of the box body 1 , and the rear end of the observation window 12 is fixedly connected to the surface of the mixing drum 201 .

[0043] With the above solution, the operator can observe the oil layer height in the mixing drum 201 through the observation window 12 .

[0044] like Figure 2 and Figure 3 As shown, the lifting assembly 7 includes a fixed box 701, a lifting column 702 and a movable block 703;

[0045] The fixed box 701 is fixedly installed in the middle of the bottom end of the box body 1, and the lifting column 702 is movably installed in the inner cavity of the fixed box 701, and the top end of the lifting column 702 passes through the box body 1 and extends to the bottom surface of the filter frame 5. The movable block 703 is arranged on one side of the lifting column 702, and the outer side of the top end of the movable block 703 is hinged to the bottom end of the linkage arm 804.

[0046] With the above solution, by providing the lifting column 702 , when the linkage arm 804 deflects, the movable block 703 and the lifting column 702 can be driven to move up and down as a whole.

[0047] like Figure 3 and Figure 8 As shown, the driving mechanism 9 includes a driving motor 901, a rotating plate 902 and a driving shaft 903;

[0048] The driving motor 901 is fixedly installed on one side of the fixed box 701, the rotating plate 902 is fixedly sleeved on the output end of the driving motor 901, and the rotating plate 902 is located outside the rectangular frame 803, and the driving shaft 903 is fixedly installed inside the two ends of the rotating plate 902, and the end of the driving shaft 903 extends to the inner cavity of the rectangular frame 803.

[0049] With the above solution, when the driving motor 901 is running, the rotating plate 902 can be driven to rotate, so that the driving shaft 903 slides inside the rectangular frame 803, thereby driving the rectangular frame 803 to move toward or away from each other.

[0050] like Figure 4 As shown, a movable door 10 is hingedly connected to the surface of the box body 1 and is located on the front of the filter frame 5 . The front of the filter frame 5 and the front of the movable door 10 are both provided with slots.

[0051] With the above solution, when the operator needs to take out the filter frame 5, he can first pull the notch of the movable door 10 to drive the movable door 10 to flip open, and then pull the notch on the front side of the filter frame 5 to pull out the filter frame 5 as a whole.

[0052] like Figure 6 As shown, the interior of the box body 1 is provided with a buffer mechanism 11 located on both sides of the bottom of the filter frame 5. The buffer mechanism 11 includes a fixing plate 1101, a support plate 1102 and a buffer assembly 1103;

[0053] The fixing plate 1101 is fixedly installed at the bottom of the inner cavity of the box body 1, and the fixing plate 1101 is located on both sides of the bottom of the filter frame 5. The support plate 1102 is movably installed at the top of the inner cavity of the fixing plate 1101. The buffer assembly 1103 is arranged between the fixing plate 1101 and the support plate 1102;

[0054] The buffer assembly 1103 includes a second limiting rod 11031 , a moving block 11032 , a buffer scissors fork 11033 and an elastic member 11034 ;

[0055] The second limiting rod 11031 is arranged on both sides of the inner end of the support plate 1102 and the buffer assembly 1103, and the buffer scissors 11033 is hinged to the inner side of the moving block 11032. The moving block 11032 is elastically connected to the fixed plate 1101 and the inner side of the support plate 1102 through the elastic member 11034.

[0056] Adopting the above scheme: through the pulling force of the elastic member 11034, the movable blocks 11032 can be pulled toward each other, and when passing through the top of the filter frame 5 upward, the movable blocks 11032 will be smoothly pulled toward each other, so that the buffer scissors 11033 can move to drive the fixed plate 1101 to move upward as a whole.

[0057] like Figure 6 As shown, the inner wall of the elastic member 11034 is slidably connected to the surface of the second limiting rod 11031.

[0058] With the above solution, through the design of the second limiting rod 11031 , the sliding of the moving block 11032 can be limited, and the elastic member 11034 can be limited synchronously when it is extended or retracted.

[0059] The working principle and use process of the present invention:

[0060] First, sesame seeds and water can be added into the interior of the mixing drum 201 through the feed pipe 203, and then the stirring component 202 can be started to stir the sesame seeds and water inside, thereby producing sesame oil, and the oil layer of the sesame oil will float to the top. At this time, the height of the oil layer can be observed through the observation window 12, so as to drive the hydraulic cylinder 401 to drive the movable torque tube 402 to move up and down as a whole to the appropriate position, and finally the oil layer can be smoothly introduced into the internal storage of the oil storage tank 404 through the movable torque tube 402 and the connecting torque tube 403.

[0061] Afterwards, the discharge valve pipe 3 can be driven to open, so that the remaining crude oil and sesame residue fall into the top of the filter frame 5 for filtration. The crude oil will be filtered smoothly through the filter frame 5 and discharged from the discharge pipe 6. When a large amount of sesame residue is accumulated on the top of the filter frame 5, the drive motor 901 can be started, so that the output end of the drive motor 901 drives the rotating plate 902 and the drive shaft 903 to rotate, so that the drive shaft 903 slides inside the rectangular frame 803, thereby driving the rectangular frame 803 to move back and forth toward and away from each other, and then the movable block 703 and the lifting column 702 can be driven up and down through the linkage arm 804.

[0062] The lifting column 702 will push the filter frame 5 upward, and the tension of the elastic member 11034 will be released, thereby pulling the two moving blocks 11032 toward each other, so that the buffer scissors 11033 can move smoothly to push the support plate 1102 as a whole to move upward, so as to maintain the supporting effect of the support plate 1102 and the connecting plate 13 on the filter frame 5. When the lifting column 702 moves downward as a whole, the bottom of the filter frame 5 will lose support, and will move downward through its own gravity and press down the support plate 1102, thereby driving the moving blocks 11032 to move away from each other through the buffer scissors 11033, thereby compressing the elastic member 11034. The elastic force of the elastic member 11034 can buffer the filter frame 5 as a whole downward to avoid a sudden drop. Finally, the filter frame 5 can be moved up and down as a whole to shake and distribute the accumulated sesame residue on the top evenly.

[0063] Finally, when stirring and removing oil, the movable door 10 notches can be clicked to drive the movable door 10 to flip open, and then the filter frame 5 side notches are clicked to extract the filter frame 5 so that the sesame residue on the filter frame 5 top is processed.
