Technical Field

[0001] The utility model relates to the technical field of fish oil processing, in particular to a leaching type fish oil falling film reaction device. Background Art

[0002] The elution type fish oil falling film reactor is an industrial equipment used to process fish oil, which usually involves purifying and refining the fish oil through a specific process. This device is designed to increase the purity of certain beneficial components in fish oil, such as EPA and DHA, which are very important for human health.

Therefore, the new type of fish oil purification uses active enzyme technology, but it has not yet been matched with an efficient and applicable reaction device. In particular, the usual falling film device is difficult to ensure the uniformity of the fish oil film when the fish oil is on the falling film device. Utility Model Content

[0022] like Figure 1-4 As shown, a liquid collecting chamber is provided in the base 11, which is characterized in that: a sieve plate 12 is fixedly connected in the liquid collecting chamber, a plurality of sieve holes 13 are provided on the sieve plate 12, a falling film cover 16 is fixedly connected to the inner circumferential surface of the sieve plate 12, the sieve plate 12 divides the liquid collecting chamber into a first cavity 14 and a second cavity 15, a dividing block 19 is fixedly connected to the end of the falling film cover 16 away from the base 11, a liquid inlet cylinder 18 is sleeved on the outer circumferential surface of the dividing block 19, the liquid inlet cylinder 18 is rotatably connected to the dividing block 19, a third cavity 17 is provided in the falling film cover 16, a rotating spindle 22 is rotatably connected in the dividing block 19, the rotating spindle 22 runs through the third cavity 17, a first gap 20 is provided between the liquid inlet cylinder 18 and the dividing block 19, a second gap 21 is provided between the liquid inlet cylinder 18 and the falling film cover 16, a driving assembly is fixedly connected to one end face of the rotating spindle 22 close to the liquid inlet cylinder 18, and a cleaning assembly is fixedly connected to one end of the rotating spindle 22 close to the base 11.

[0023] The arrangement of the first slit 20 and the second slit 21 ensures that the fish oil stock solution maintains a thin film state when it flows onto the falling film cover 16 on which lipase is arranged.

[0024] A sleeve 25 is fixedly mounted on the outer circumferential surface of the rotating main shaft 22 located in the third cavity 17, and a plurality of telescopic blocks 26 are fixedly connected to the outer circumferential surface of the sleeve 25. An electric lamp 27 is slidably connected to the telescopic blocks 26. The telescopic blocks 26 are arranged on the outer circumferential surface of the sleeve 25 with an arc equilaterally centered on the rotating main shaft 22. It is worth noting that the telescopic blocks 26 and the electric lamps 27 are both prior art.

[0025] The driving assembly includes an impeller main shaft 23 and a plurality of blades 24. The impeller main shaft 23 is fixedly connected to an end face of the rotating main shaft 22 close to the partition block 19. One end of the blade 24 is fixedly connected to the outer cylindrical surface of the impeller main shaft 23, and the other end of the blade 24 is fixedly connected to the liquid inlet cylinder 18.

[0026] The cleaning assembly includes a swing arm 28 and a brush head 29. An annular groove 30 is provided along the sieve hole 13 at one end of the sieve plate 12 close to the second cavity 15. One end of the swing arm 28 is fixedly connected to the outer cylindrical surface of the rotating main shaft 22, and the other end of the swing arm 28 is fixedly connected to the brush head 29. The brush head 29 is slidably connected to the annular groove 30. A plurality of sieve holes 13 are penetrated through the sieve plate 12 with the rotating main shaft 22 as the axis and have an equal arc. The diameter of the sieve hole 13 is equal to the width of the annular groove 30.

[0027] When the fish oil falling film reaction is performed in this scheme, first, the distance between the electric lamp 27 and the sleeve 25 is adjusted by the telescopic block 26 and the electric lamp 27 is started to illuminate the falling film cover 16, and the fish oil stock solution is poured into the liquid cylinder 18, and the fish oil stock solution flows to the surface of the falling film cover 16 along the first slit 20 and the second slit 21.

[0028] When the fish oil stock solution is poured into the liquid cylinder 18, the fish oil stock solution impacts the blades 24, generating thrust on the blades 24, so that the blades 24 drive the impeller main shaft 23 to rotate, and the impeller main shaft 23 drives the rotating main shaft 22 to rotate around itself as the axis core, and the rotating main shaft 22 drives the telescopic block 26 and the electric lamp 27 to rotate around the rotating main shaft 22 as the axis core through the sleeve 25, so that the electric lamp 27 can illuminate the falling film cover 16 more evenly.

[0029] Then, the fish oil stock solution undergoes a photocatalytic reaction under light exposure on the falling film cover 16 , enters the first cavity 14 , and then enters the second cavity 15 through the sieve hole 13 . The sieve hole 13 filters the sediment produced by the photocatalytic reaction of the fish oil stock solution, and the fish oil flows out from the liquid outlet 31 .

[0030] Finally, since the rotating main shaft 22 drives the swing arm 28 to rotate around the rotating main shaft 22 as the axis, the swing arm 28 drives the brush head 29 to slide along the annular groove 30, thereby pushing out the sediment blocking the sieve hole 13, ensuring that the fish oil flows from the first cavity 14 into the second cavity 15.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
