DETAILED DESCRIPTION

[0039] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0040] like Figures 1 to 5 As shown, a fish oil decolorizing stirring tank comprises a stirring tank body 1 and a sleeve shaft 4 rotatably arranged on the upper surface of the stirring tank body 1. The fish oil decolorizing stirring tank also comprises:

[0041] A top bracket 2 is fixed to the upper surface of the mixing tank body 1.

[0042] The stirring shaft 7 disposed on the lower surface of the stirring tank body 1 is rotated, the top end of the stirring shaft 7 passes through the sleeve shaft 4, and the top end of the stirring shaft 7 is rotatably connected to the top bracket 2.

[0043] At least three crank arms 5 are fixed on the sleeve shaft 4.

[0044] A stirring strip 6 is fixed to the bottom end of the crank arm 5.

[0045] The inner bracket 8 is fixed in the stirring tank body 1, and the inner bracket 8 is annular as a whole, and the curved arm 5 is located above the inner bracket 8, and the curved arm spans the inner and outer sides of the inner bracket 8, so that the stirring strips 6 and the stirring shaft 7 are located on the inner and outer sides of the inner bracket 8. When the fish oil is stirred, the flow and rotation directions of the fish oil outside and inside the inner bracket 8 are opposite, thereby improving the collision mixing uniformity and efficiency between the fish oil and the pigment adsorbent, and improving the efficiency and effect of fish oil decolorization.

[0046] A plurality of pull shafts 9 are slidably sleeved on the inner bracket 8.

[0047] A tension spring 10 is slidably mounted on the upper end of the tension shaft 9, and two ends of the tension spring 10 are respectively fixed on the tension shaft 9 and the inner bracket 8.

[0048] The upper limit block 11 arranged at the bottom end of the pull shaft 9 is rotated.

[0049] The lower limit block 12 disposed on the lower surface of the mixing tank body 1 is rotated.

[0050] A transmission assembly 3 is used for linkage between the sleeve shaft 4 and the stirring shaft 7.

[0051] A driving motor 17 is used to drive the stirring shaft 7 to rotate.

[0052] In this embodiment, the transmission assembly 3 includes:

[0053] The upper gear 32 is fixedly sleeved on the top end of the stirring shaft 7.

[0054] The lower gear 33 is fixedly sleeved on the top end of the sleeve shaft 4.

[0055] The double-toothed shaft 31 disposed on the upper surface of the mixing tank body 1 is rotated.

[0056] The transmission teeth 34 disposed between the double-toothed shaft 31 and the lower gear 33 are rotated.

[0057] The output shaft of the driving motor 17 drives the stirring shaft 7 to rotate. The rotating stirring shaft 7 transmits power through the upper gear 32, the double-toothed shaft 31, the transmission gear 34 and the lower gear 33, so that the driving motor 17 indirectly drives the sleeve shaft 4 to rotate, thereby realizing the reverse rotation of the stirring shaft 7 and the sleeve shaft 4. In addition, the number of teeth at the top and bottom of the double-toothed shaft 31 is set to different gear ratios, so that the rotation speeds of the stirring shaft 7 and the sleeve shaft 4 are different, and the fish oil in the stirring tank body 1 flows in two directions and collides with each other, thereby improving the mixing uniformity of the fish oil and the pigment adsorbent and the stirring and mixing efficiency.

[0058] In this embodiment, the two sides of the transmission tooth 34 are respectively meshed with the tooth surfaces of the lower gear 33 and the bottom end of the double-toothed shaft 31, and the tooth surface of the top end of the double-toothed shaft 31 is meshed with the upper gear 32. Due to the rotation characteristics of the two adjacent gears in opposite directions, the upper gear 32 and the double-toothed shaft 31 are directly transmitted, while the lower gear 33 and the double-toothed shaft 31 are transmitted via the transmission tooth 34. Therefore, the rotation directions of the sleeve shaft 4 and the stirring shaft 7 are opposite, so that the flow direction of the fish oil in the stirring tank body 1 is in two opposite directions, so that the fish oil and the pigment adsorbent added therein can be fully collided and mixed, thereby improving the mixing uniformity of the fish oil and the Serford adsorbent, and improving the mixing and stirring efficiency between the two, and improving the effect and efficiency of fish oil decolorization.

[0059] In this embodiment, the fish oil decolorization stirring tank also includes:

[0060] The dye adsorbent plate 15 is provided between the upper limit block 11 and the lower limit block 12 .

[0061] The upper limit plug block 14 and the lower limit plug block 16 are respectively fixed to the upper and lower surfaces of the pigment adsorbent plate 15, the upper limit plug block 14 is plugged into the limit slot 13 provided on the lower surface of the upper limit block 11, and the lower limit plug block 16 is plugged into the limit slot 13 provided on the upper surface of the lower limit block 12. When the pigment adsorbent plate 15 needs to be replaced, the pigment adsorbent plate 15 is first lifted vertically upward so that it pushes the pull shaft 9 upward and stretches the tension spring 10 until the lower limit plug block 16 on the pigment adsorbent plate 15 is disengaged from the limit slot 13 on the lower limit block 12, and then quickly pulled out diagonally downward The pigment adsorbent plate 15 can be removed. During installation, the upper limit plug block 14 on the pigment adsorbent plate 15 is first inserted into the limit slot 13 on the lower surface of the upper limit block 11, and then the pigment adsorbent plate 15 is lifted vertically upward so that it pushes the pull shaft 9 upward and lengthens the tension spring 10, and then the lower limit plug block 16 is aligned with the limit slot 13 on the lower limit block 12 and inserted therein, and the replacement operation of the pigment adsorbent plate 15 can be completed. Under the premise of not affecting the rotation effect of the pigment adsorbent plate 15, the replacement efficiency of the pigment adsorbent plate 15 is improved and the difficulty of the replacement operation is reduced.

[0062] In this embodiment, the inner bracket 8 is located between the stirring bar 6 and the stirring shaft 7, and the inner bracket 8 is located below the curved arm 5. Such a design can separate the fish oil into two concentric areas when the fish oil is stirred, and make the flow directions of the fish oil in the two areas opposite, so that the pigment adsorbent plate 15 swings under the impact of fish oil in different flow directions, thereby increasing the contact probability between the fish oil and the pigment adsorbent plate 15, and can improve the mixing uniformity of the fish oil and the color adsorbent, thereby improving the efficiency and effect of fish oil decolorization.

[0063] In this embodiment, the cross-section of the pigment adsorbent plate 15 is S-shaped, and the pigment adsorbent plates 15 are equidistantly distributed outside the stirring shaft 7 along the circumferential direction. By surrounding the stirring shaft 7 with a plurality of pigment adsorbent plates 15, the stirring shaft 7 and the stirring strip plate 6 are separated, so that when the fish oil is stirred, the flowing fish oil impacts the S-shaped pigment adsorbent plate 15, causing it to swing to a certain extent in the fish oil, thereby increasing the contact probability between the fish oil and the pigment adsorbent plate 15, and improving the efficiency and effect of fish oil decolorization.

[0064] The above description is only the preferred embodiment of the utility model, and the parts not described in the utility model can be implemented by adopting or drawing on existing technologies. Of course, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples. The changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the utility model should also fall within the protection scope of the utility model.
