Technical Field

[0001] The utility model relates to the technical field of differential pressure flash evaporation equipment, in particular to differential pressure flash evaporation equipment for rapeseed oil pressing. Background Art

[0002] As we all know, during the production of rapeseed oil, the rapeseed needs to be dehydrated by flash evaporation first, and then pressed into oil. The boiling point of a substance increases with increasing pressure and decreases with decreasing pressure; the high-pressure and high-temperature fluid is decompressed to reduce its boiling point and enters the flash tank. At this time, the fluid temperature is higher than the boiling point under the pressure. The fluid boils and vaporizes rapidly in the flash tank, and the two phases are separated. The water in the rapeseed is rapidly vaporized to achieve the purpose of dehydrating the rapeseed.

[0003] When the existing differential pressure flash evaporation equipment is used to dehydrate rapeseed, it is easy for the rapeseed located at the outermost part to be quickly dehydrated and dried, while the rapeseed in the middle part cannot be fully dehydrated, which in turn affects the dehydration and drying effect of the rapeseed. Moreover, it takes a longer time to dehydrate the wet and clumped rapeseed, which affects the efficiency of rapeseed drying. Therefore, it is necessary to design a differential pressure flash evaporation equipment for rapeseed oil pressing. Utility Model Content

The top of the inner part of the tank body 1 is fixedly connected with the barrel 18, and the barrel 18 is located at the lower end of the feed hopper 6. The bottom end of the barrel 18 is fixedly connected with the filter plate 24, and the inner part of the filter plate 24 is rotatably connected with the rotating shaft 21. The circumferential surface of the rotating shaft 21 is fixedly connected with the flapping blade 22, and the flapping blade 22 is located in the barrel 18. The bottom end of the rotating shaft 21 is installed with a linkage assembly, and the rotating rod 10 is connected to the rotating shaft 21 through the linkage assembly, and the rotating rod 10 provides power for the rotating shaft 21 to operate through the linkage assembly. When working, the utility model can fully heat the rapeseed more evenly, and then improve the drying and dehydration effect and efficiency of the rapeseed under the mutual cooperation of the vacuum pump 4 and the compressor, so as to facilitate the subsequent pressing of the dehydrated and dried rapeseed into oil.

[0022] Furthermore, a temperature detector 20 and an air pressure detector 19 are fixedly connected to the top of the inner part of the tank body 1. When working, the temperature detector 20 and the air pressure detector 19 can detect the temperature and air pressure inside the tank body 1 respectively.

[0023] Furthermore, the first scraper 9 is fixedly connected to one end of the second stirring blade 12 close to the inner wall of the tank body 1, and the second scraper 14 is fixedly connected to one end of the third stirring blade 13 close to the inner wall of the discharge hopper 2. The first scraper 9 and the second scraper 14 are respectively attached to the tank body 1 and the discharge hopper 2. When working, the first scraper 9 and the second scraper 14 can scrape the inner walls of the tank body 1 and the discharge hopper 2 to prevent residual rapeseed from adhering to the inner walls of the tank body 1 and the discharge hopper 2.

[0024] Furthermore, the linkage assembly includes a ring gear 15 and a gear 23. The circumferential surface of the rotating rod 10 is fixedly connected with the ring gear 15, and the bottom end of the rotating shaft 21 is fixedly connected with the gear 23, and the gear 23 meshes with the ring gear 15. During operation, the rotating rod 10 rotates to drive the ring gear 15 to rotate, and at this time, with the cooperation of the gear 23, the rotating shaft 21 is driven to rotate, and then the flapping leaves 22 are driven to rotate. Therefore, with the cooperation of the rotating rod 10, the linkage assembly can provide power for the rotating shaft 21 and the flapping leaves 22 to rotate.

[0025] Further, a bearing seat is fixedly connected to the inner top of the tank body 1, and the rotating rod 10 passes through the bearing seat and is rotatably connected to the bearing seat. During operation, under the action of the bearing seat, the rotating rod 10 is rotated more smoothly.

[0026] Furthermore, the rotating shaft 21 extends upward into the feed hopper 6. During operation, when rapeseed is added along the feed hopper 6, the existence of the rotating rotating shaft 21 can reduce the probability of the feed hopper 6 being blocked due to feeding.

[0027] Furthermore, a plurality of supporting legs 17 are fixedly connected to the bottom end of the tank body 1. When working, under the action of the supporting legs 17, the tank body 1 can be supported on the ground more stably.

[0028] Working principle:

[0029] When in use, the motor 7 is controlled to operate, and the motor 7 drives the rotating rod 10 to rotate, and the rotating rod 10 drives the first stirring blade 11, the second stirring blade 12, the third stirring blade 13 and the gear ring 15 to rotate, and then the sealing plug 8 is pulled out, and the rapeseed is poured into the interior of the tank body 1 along the feed hopper 6, and the poured rapeseed slides along the barrel 18 and falls through the filter plate 24. For the rapeseed that is clumped together, the rotation of the gear ring 15 drives the gear 23 to rotate, and then drives the rotating shaft 21 and the beating blade 22 to rotate, and the beating blade 22 beats the clumped rapeseed to disperse it, and the dispersed rapeseed will pass through the filter plate 24 and fall, so that the rapeseed that falls into the tank body 1 is all dispersed rapeseed. After the feeding is completed, the sealing plug 8 is installed in the feed hopper 6, and then the rapeseed is fully stirred with the cooperation of the first stirring blade 11, the second stirring blade 12 and the third stirring blade 13. Stir and disperse, so that it is convenient to use the heating plate 16 to heat the rapeseed more evenly, and then turn on the air compressor 5 to compress the air, and enter the tank body 1 along the exhaust pipe, so that the air pressure inside the tank body 1 gradually rises, until the air pressure and temperature inside the tank body 1 reach the set value, turn on the vacuum pump 4, and use the suction pipe to extract the air inside the tank body 1 and discharge it to the outside. At this time, the moisture in the rapeseed will be instantly vaporized, and the vaporized moisture will be discharged through the vacuum pump 4. During the process of dehydrating and drying the rapeseed, it is constantly stirred by multiple stirring blades, so that the rapeseed can be more evenly and fully dehydrated and dried, thereby ultimately improving the drying and dehydration effect and efficiency of the rapeseed. For the rapeseed that has been dried, open the discharge valve 3 to discharge it from the discharge hopper 2, so that the dehydrated rapeseed can be squeezed into oil later.
