Description

Technical Field

[0001] The utility model relates to the technical field of filtration, in particular to a filtration device for oleic acid processing. Background Technique

[0002] After the hydrolysis of oil and fat, mixed fatty acids and glycerol are obtained. The mixed fatty acids mainly include stearic acid, palmitic acid and oleic acid. It is necessary to separate these three fatty acids to obtain higher-purity oleic acid. The principle is to filter using the different melting points and boiling points of the three acids. First, the mixed fatty acids are frozen into a paste and then placed inside a filter press. When the temperature reaches 15 °C, oleic acid changes from a solid state to a liquid state and is separated.

[0003] The existing filtration equipment only filters the same kind of oleic acid. The heated oleic acid is filtered through a filter press to obtain the required oleic acid, and the remaining crystals are discharged from the filter press for the next process. The remaining oleic acid crystals are reheated until they melt and then enter the filter press for filtration. The process is relatively cumbersome and the filtration efficiency is relatively low.

[0004] Therefore, we propose a filtration device for oleic acid processing. Content of the Utility Model

[0005] The purpose of the utility model is to provide a filtration device for oleic acid processing to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A filtration device for oleic acid processing, including a filter press, a bracket is fixedly connected to the side of the filter press, a conductive slide rail is fixedly connected to the outer surface of the upper end of the filter press, a conductive slider is slidably connected to the surface of the conductive slide rail, and a filter plate for filtering oleic acid is provided at the lower end of the conductive slider;

[0007] A bumping component is arranged on the outer surface of the upper end of the bracket. When the filtration is completed, the filter plate slides along the bracket. At this time, the bumping component makes the moving filter plate bump up and down to shake off the filter residue adhering to the surface.

[0008] A liquid discharge component is arranged at the lower end of the filter plate, which can automatically switch the liquid discharge position according to the temperature of the filtered material, saving the liquid discharge time.

[0009] Among them, the bumping component includes a blocking block, the blocking block is designed with an inclined structure and is fixedly connected to the outer surface of the upper end of the bracket, a fixing block is fixedly connected to the corresponding position of the filter plate and the blocking block, and a flipping block is connected to the position of the fixing block away from the filter plate.

[0010] Among them, the flipping block is rotatably connected to the edge of the fixing block through a rotating shaft, and an elastic band is fixedly connected between the flipping block and the filter plate.

[0011] Among them, a telescopic tube is fixedly connected to the outer surface of the upper end of the filter press plate. A telescopic block is sleeved inside the telescopic tube, and the upper end of the telescopic block is fixedly connected to a conductive slider.

[0012] Among them, the liquid discharge assembly includes an electric heating ring, which is fixedly connected to the annular inner surface of the filter press plate. A pipe I communicating with the inside of the filter press plate is fixedly connected to the outer surface of the lower end of the filter press plate. One end of the pipe I away from the filter press plate is slidably connected to a pipe III.

A guide groove is formed on the annular inner surface of the pipe II, and a guide block fixed to the pipe III is slidably connected inside the guide groove.

[0015] The utility model has at least the following beneficial effects:

[0016] By setting the liquid discharge assembly, after the separation of liquid oleic acid by the filter press plate is completed, the remaining oleic acid crystals inside the filter press plate can be heated by the electric heating ring to make the remaining oleic acid crystals reach the melting point. By changing the temperature, the spring expands when heated and pushes the pipe III to gradually move away from the pipe I along the pipe II under the guidance of the guide block. At this time, the pipe III crosses the partition inside the liquid discharge groove and aligns with the other area of the liquid discharge groove separated by the partition.

Specific implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-6 , the present utility model provides a technical solution: a filtering device for oleic acid processing, including a filter press 1, a support 10 is fixedly connected to the side of the filter press 1, a conductive slide rail 11 is fixedly connected to the outer surface of the upper end of the filter press 1, a conductive slider 12 is slidably connected to the surface of the conductive slide rail 11, and a filter plate 13 for filtering oleic acid is provided at the lower end of the conductive slider 12;

[0026] A bump assembly 3, the bump assembly 3 is provided on the outer surface of the upper end of the support 10. After the filtering is completed, the filter plate 13 slides along the support 10. At this time, the bump assembly 3 makes the moving filter plate 13 bump up and down, shaking off the filter residue adhering to the surface;

[0027] A liquid discharge assembly 2, the liquid discharge assembly 2 is provided at the lower end of the filter plate 13, and can automatically switch the liquid discharge position according to the temperature of the filtered material, saving the liquid discharge time.

[0028] The bump component 3 includes a blocking block 33 which is designed with an inclined structure and is fixedly connected to the outer surface of the upper end of the bracket 10. A fixing block 30 is fixedly connected to the corresponding position of the filter pressing plate 13 and the blocking block 33. A turning block 31 is connected to the position of the fixing block 30 away from the filter pressing plate 13. After the filter pressing plate 13 completes the filter pressing, it slides along the direction of the electric slide rail 11 under the control of the electric guide block 27. At this time, the fixing block 30 and the turning block 31 will contact the blocking block 33 with an inclined structure design and move upward along the blocking block 33 until they cross the blocking block 33. At this time, the slowly rising filter pressing plate 13 loses contact with the blocking block 33 and suddenly moves downward, colliding with the bracket 10, causing the filter pressing plate 13 itself to vibrate and shake off the filter residue on the surface, thus facilitating the cleaning of the filter pressing plate 13.

[0029] The turning block 31 is rotationally connected to the edge of the fixing block 30 through a rotating shaft. A elastic band 32 is fixedly connected between the turning block 31 and the filter pressing plate 13. When the filter pressing plate 13 is ready for filter pressing, it will gather close to one side of the filter press 1. The turning block 31 will contact the blocking block 33. The blocking block 33 forces the turning block 31 to turn and stretches the elastic band 32. At this time, the contact between the turning block 31 and the blocking block 33 will not affect the movement of the filter pressing plate 13. Through the above structure, only the movement of the filter pressing plate 13 after the filter pressing is completed will form an oscillation of the filter pressing plate 13 through the blocking block 33.

[0030] A telescopic tube 35 is fixedly connected to the outer surface of the upper end of the filter pressing plate 13. A telescopic block 34 is sleeved inside the telescopic tube 35. The upper end of the telescopic block 34 is fixedly connected to the conductive slider 12. The telescopic tube 35 and the telescopic block 34 cooperate to provide guiding and limiting for the filter pressing plate 13.

[0031] The liquid discharging component 2 includes an electric heating ring 14 which is fixedly connected to the annular inner surface of the filter pressing plate 13. A pipe one 23 communicating with the inside of the filter pressing plate 13 is fixedly connected to the outer surface of the lower end of the filter pressing plate 13. One end of the pipe one 23 away from the filter pressing plate 13 is slidably connected to a pipe three 29. A liquid discharging groove 20 is fixedly connected to the outer surface of the bracket 10 at the corresponding position of the pipe three 29. A partition 21 is fixedly connected to the inner surface of the liquid discharging groove 20. A liquid discharging port 22 is opened at the end of the liquid discharging groove 20. The electric heating ring 14 can keep the oleic acid crystals being filtered warm or change the temperature, so that the oleic acid crystals gradually melt with the temperature change, completing the mutual separation between different oleic acids and improving the filtering efficiency. When the filter pressing plates 13 are pressed tightly against each other, the solenoid valve inside the filter pressing plate 13 opens the pipe one 23. At this time, the liquid oleic acid inside the filter pressing plate 13 will flow along the pipe one 23 and the pipe three 29 towards the liquid discharging groove 20, and the oleic acid is collected through the liquid discharging groove 20.

[0032] A pipe two 24 is provided between the pipe one 23 and the pipe three 29. The pipe two 24 is fixedly connected to the end of the pipe one 23. The pipe three 29 is located inside the pipe two 24. A spring 25 that extends when heated is fixedly connected between the pipe three 29 and the pipe one 23. The spring 25 is made of shape memory alloy. The inner surfaces of the pipe one 23 and the pipe three 29 are both sleeved with a conduit 26. The conduit 26 is fixedly connected to the pipe one 23. After the liquid oleic acid at a certain temperature is discharged completely, the temperature of the oleic acid crystal inside the pressure filter plate 13 is increased through the electric heating ring 14 to melt the oleic acid crystal originally in a crystal state. At this time, since the temperature of the pressure filter plate 13 gradually rises, the temperature is gradually conducted to the surface of the spring 25. The spring 25 will push the pipe three 29 to slide inside the pipe two 24 after being heated, thereby increasing the length of the entire pipe one 23 and the pipe three 29. At this time, the pipe three 29 crosses the partition 21 inside the liquid discharge groove 20 and aligns with another area separated by the partition 21 inside the liquid discharge groove 20. By changing the temperature, the telescopic amount of the pipe three 29 is controlled, so as to achieve the purpose of discharging different oleic acids separately and improve the filtration efficiency.

[0033] The upper end of the pipe two 24 is fixedly connected with a heat conduction pipe 241. The upper end of the heat conduction pipe 241 is fixedly connected to the electric heating ring 14. A guide groove 28 is formed on the annular inner surface of the pipe two 24. A guide block 27 fixedly connected to the pipe three 29 is slidably connected inside the guide groove 28. The heat conduction pipe 241 is filled with liquid water for heat absorption. The liquid water is also in the cavity between the pipe two 24 and the conduit 26 to exchange heat with the spring 25, increasing the stability of this structure.
