DETAILED DESCRIPTION

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0020] Example 1, as Figures 1 to 5 As shown, an alkali refining device for cottonseed oil includes an alkali refining tank 1, an oil outlet pipe 2, and a heater 3. The alkali refining tank 1 has an alkali refining chamber inside. The oil outlet pipe 2 is installed at the bottom of the alkali refining tank 1, and the heater 3 is installed on the outer wall of the alkali refining tank 1. It also includes a baffle plate 4, an oil filling pipe 5, an alkali solution pipe 6, a shaft pipe 7, multiple through holes 8, and multiple stirring blades 9. The baffle plate 4 is horizontally installed in the upper part of the alkali refining chamber of the alkali refining tank 1, dividing the alkali refining chamber into an upper and lower part. The oil filling pipe 5 and the alkali solution pipe 6 are installed at the top of the alkali refining tank 1, with their output ends extending into the upper part of the alkali refining chamber of the alkali refining tank 1. The lower part of the shaft pipe 7 passes through the top of the alkali refining tank 1 and the baffle plate 4, extending into the lower part of the alkali refining chamber of the alkali refining tank 1. The tube 7 is rotatably connected to the top of the alkali refining tank 1 and the partition 4. The tube 7 is hollow inside, and multiple through holes 8 are provided on the side wall of the tube 7. The multiple through holes 8 are located above and below the partition 4, respectively. Multiple stirring blades 9 are installed on the outer wall of the tube 7. It also includes a motor 10, a driving wheel 11, a driven wheel 12 and a transmission belt 13. The motor 10 is installed on the alkali refining tank 1. The output shaft of the motor 10 is concentrically mounted on the driving wheel 11. The driven wheel 12 is concentrically mounted on the upper end of the tube 7. The transmission belt 13 is fitted on the driving wheel 11 and the driven wheel 12. It also includes an upper blade 22. The upper blade 22 is installed on the outer wall of the tube 7. The upper blade 22 is located in the upper part of the alkali refining chamber of the alkali refining tank 1 and above the partition 4.

[0021] During operation, cottonseed oil is fed into the upper part of the alkali refining chamber of the alkali refining tank 1 through the oiling pipe 5, and alkali solution is fed into the upper part of the alkali refining chamber of the alkali refining tank 1 through the alkali solution pipe 6. The motor 10 drives the drive wheel 11 to rotate, and the drive wheel 11 drives the driven wheel 12 and the shaft tube 7 to rotate through the transmission belt 13. When the shaft tube 7 rotates, it drives the upper blade 22 to rotate. The upper blade 22 stirs the cottonseed oil and alkali solution above the partition 4, so that the cottonseed oil and alkali solution are initially mixed on the partition 4. The mixture enters the shaft tube 7 through the through hole 8 above the partition 4, and is transported through multiple through holes 8 below the partition 4. The mixture is introduced into the lower part of the alkali refining chamber of the alkali refining tank 1. The shaft tube 7 drives multiple stirring blades 9 to rotate, and the multiple stirring blades 9 thoroughly mix the mixture. The heater 3 heats the mixture in the alkali chamber of the alkali refining tank 1, causing the mixture to undergo an alkali refining reaction. After the alkali refining reaction is completed, the valve of the oil outlet pipe 2 is opened to discharge the alkali-refined cottonseed oil. Compared with the existing technology, the cottonseed oil and alkali are initially mixed in the upper part of the alkali refining chamber, and then mixed and alkali-refined in the lower part of the alkali refining chamber. The mixture is transported through the shaft tube 7, and the size of the multiple stirring blades 9 is not limited, thereby improving the stirring effect.

[0022] Example 2, as Figures 1 to 5 As shown, based on Embodiment 1, it also includes an inner tube 14, a rotating shaft 15, and a handwheel 16. The inner tube 14 is rotatably installed inside the shaft tube 7. A slot is provided on the inner tube 14. The rotating shaft 15 is installed at the upper end of the inner tube 14. The upper end of the rotating shaft 15 extends out of the top end of the shaft tube 7. The handwheel 16 is installed at the top end of the rotating shaft 15. The handwheel 16 is located above the shaft tube 7. It also includes a lever 17 and a slot 18. The middle part of the lever 17 is hinged to the handwheel 16. Multiple slots 18 are provided around the upper circumference of the shaft tube 7. The lower end of the lever 17 is inserted into the slot 18.

[0023] Rotating the shaft 15 by handwheel 16 causes the inner tube 14 and the shaft tube 7 to rotate relative to each other, aligning the slots of the inner tube 14 with the multiple through holes 8. This allows the interior of the shaft tube 7 to communicate with the outside through the slots and through holes 8. At this time, the cottonseed oil and alkali solution above the partition 4 can be conveyed to the lower part of the partition 4 through the shaft tube 7. Rotating the shaft 15 again by handwheel 16 causes the slots of the inner tube 14 to be misaligned with the multiple through holes 8, blocking the multiple through holes 8 of the shaft tube 7. At this time, the cottonseed oil and alkali solution above the partition 4 cannot be conveyed to the lower part of the partition 4 through the shaft tube 7. This allows the cottonseed oil and alkali solution above and below the partition 4 to be initially mixed and fully mixed, improving the mixing effect. Moreover, while the alkali refining chamber at the bottom of the alkali refining tank 1 is being fully mixed, the upper part of the alkali refining chamber of the alkali refining tank 1 is fed again for initial mixing, realizing dual-station mixing alkali refining.

[0024] The lower end of the push rod 17 is inserted into the clamping groove 18, so that the hand wheel 16 is locked relative to the shaft tube 7 through the push rod 17. When the relative angle between the inner tube 14 and the shaft tube 7 needs to be adjusted, the upper part of the push rod 17 is pressed inward, so that the lower part of the push rod 17 moves outward and is separated from the clamping groove 18. At this time, the hand wheel 16, the rotating shaft 15 and the inner tube 14 can be rotated to facilitate adjustment.

The wave shape two is engaged and matched with the wave shape one and is sealed. The side wall of the piston insertion rod 19 is provided with the limiting block 20. The limiting block 20 is slidingly connected with the limiting groove of the inner wall of the lower end of the shaft tube 7. The tension spring 21 is sleeved on the piston insertion rod 19. The upper end of the tension spring 21 is connected with the shaft tube 7. The lower end of the tension spring 21 is connected with the piston insertion rod 19. The elastic force of the tension spring 21 pulls the piston insertion rod 19 upward.

[0026] The elastic force of the tension spring 21 pulls the piston insertion rod 19 upward. When the slotted opening of the inner tube 14 is aligned with the plurality of through holes 8, the wave shape two of the upper end of the piston insertion rod 19 is engaged with the wave shape one of the inner tube 14, so as to seal and close the lower end port of the inner tube 14. When the slotted opening of the inner tube 14 is staggered with the plurality of through holes 8, so that the side wall of the inner tube 14 blocks the plurality of through holes 8, the vertex of the wave shape two of the upper end of the piston insertion rod 19 is connected with the low point of the wave shape one of the inner tube 14, so as to move the piston insertion rod 19 downward, thereby opening the lower end port of the inner tube 14. The opening of the shaft tube 7 is also opened, so as to enable the residual cottonseed oil and alkali solution in the shaft tube 7 to be discharged through the lower end port of the inner tube 14 and the opening of the shaft tube 7, thereby reducing the residue.

[0027] As shown in Example 3, Figures 1 to 6As shown, the alkali refining device for cottonseed oil of the utility model, when working, firstly motor 10 drives driving wheel 11 to rotate, driving wheel 11 drives driven wheel 12 and shaft tube 7 to rotate through transmission belt 13, shaft tube 7 drives upper blade 22 and multiple stirring blades 9 to rotate, cottonseed oil is input to the upper portion of alkali refining chamber of alkali refining tank 1 through oil feeding pipe 5, alkali liquor is input to the upper portion of alkali refining chamber of alkali refining tank 1 through alkali liquor pipe 6, upper blade 22 stirs cottonseed oil and alkali liquor to preliminarily mix on baffle 4, then through hand wheel 16 to rotate shaft 15, make shaft 15 drive inner tube 14 relatively rotate with shaft tube 7, make the slot of inner tube 14 align with multiple through holes 8, mixed solution enters the inside of shaft tube 7 through through hole 8 above baffle 4, and is input to the lower portion of alkali refining chamber of alkali refining tank 1 through multiple through holes 8 below baffle 4, then mixed solution conveying is completed, through hand wheel 16 to rotate shaft 15, make shaft 15 drive inner tube 14 relatively rotate with shaft tube 7, make the slot of inner tube 14 stagger with multiple through holes 8, close multiple through holes 8, multiple stirring blades 9 mix the mixed solution sufficiently, heater 3 heats the mixed solution in the alkali liquor chamber of alkali refining tank 1, makes the mixed solution carry out alkali refining reaction, finally, after alkali refining reaction is completed, the valve of oil outlet pipe 2 is opened, and the cottonseed oil after alkali refining can be discharged.
