Description

Technical Field

[0001] This utility model relates to a decolorization device for the biological production of succinic acid, belonging to the field of succinic acid production technology. Background Technology

[0002] The biological production of succinic acid is a green process that utilizes microbial fermentation to convert renewable carbon sources (such as glucose, starch, and cellulose hydrolysate) into succinic acid. Compared with traditional petroleum-based production, it has advantages such as being environmentally friendly, using sustainable raw materials, and producing high-purity products.

[0003] In the biological production of succinic acid, decolorization is an essential purification step. Decolorization removes pigments, some residual organic matter, colloids, and trace impurities from the feed solution, thereby improving the purity and grade of the product.

[0004] Traditional succinic acid decolorization typically employs activated carbon fixed beds, where the feed solution relies on gravity or low-pressure pumping to pass through the fixed bed. This method suffers from slow flow rate, long residence time, and low efficiency. Furthermore, traditional fixed beds are prone to channeling, short-circuiting, or uneven resistance due to bed compaction, resulting in incomplete decolorization of some materials and inconsistent decolorization effects.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This invention addresses the shortcomings of the prior art by providing a decolorization device for the biological production of succinic acid, which can solve the problems of low decolorization efficiency and long time, as well as the problems of uneven decolorization and unstable effect.

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] A decolorization device for the biological production of succinic acid includes a shell. A driving disc and a driven disc are symmetrically arranged vertically in the upper part of the shell's inner cavity. Multiple activated carbon filter elements are sequentially nested between the driving and driven discs from the inside out, with the number of filter elements increasing sequentially from the inside out. The driving and driven discs are connected to multiple connecting rods distributed circumferentially. The top of the driving disc is fixedly connected to a driving shaft, and the bottom of the driven disc is fixedly connected to a driven shaft. The axes of the driving and driven shafts are collinear.

[0009] Furthermore, the drive shaft is hollow inside, and the top of the drive shaft is connected to the feed pipe via a rotary joint.

[0010] Furthermore, the two ends of the connecting rod are provided with flanges that are connected to the driving disc and the driven disc.

[0011] Furthermore, both the active and driven discs have multiple annular protrusions on their opposing inner sides, which enable the positioning and installation of the activated carbon filter element.

[0012] Furthermore, a feed hole is provided at the center of the active disc, which connects the inner cavity of the active shaft to the innermost cavity of the activated carbon filter element.

[0013] Furthermore, the drive shaft passes vertically through the hollow motor and the bearing housing.

[0014] Furthermore, the hollow motor is fixed to the cover plate on the top of the housing.

[0015] Furthermore, the bearing housing is fixed to the support frame, and the support frame is fixed to the cover plate on the top of the housing.

[0016] Furthermore, the driven shaft is rotatably mounted inside the bracket, which is fixed to the inner wall of the housing.

[0017] Furthermore, a discharge pipe is provided at the bottom of the inner cavity of the shell, and a discharge valve is installed on the pipe.

[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0019] This invention utilizes centrifugal force for forced filtration, which accelerates the filtration speed, shortens the decolorization cycle, and improves production efficiency.

[0020] The activated carbon filter element in this invention adopts a nested design, with multi-stage series penetration and centrifugal force-driven uniform radial flow, ensuring that all liquids must pass through each filter element layer for full adsorption, significantly improving the uniformity and consistency of the decolorization effect.

[0021] This invention employs upper and lower double bearing support and a collinear axis design to provide excellent rigidity and dynamic balance performance, effectively suppressing vibration and ensuring stable operation under high speed and heavy load.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0027] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0028] like Figures 1-3 As shown in the figure, this utility model provides a decolorization device for the biological production of succinic acid, including a shell 1. The upper part of the inner cavity of the shell 1 is equipped with an active disk 3 and a driven disk 4 symmetrically arranged in the vertical direction. Multiple activated carbon filter elements 6 are installed between the active disk 3 and the driven disk 4, arranged sequentially from the inside to the outside. The number of activated carbon filter elements 6 increases sequentially from the inside to the outside. The active disk 3 and the driven disk 4 are connected to multiple connecting rods 5 distributed in a circle.

[0029] The top of the active disk 3 is fixedly connected to the active shaft 8, and the bottom of the driven disk 4 is fixedly connected to the driven shaft 15. The axes of the active shaft 8 and the driven shaft 15 are collinear.

[0030] The connecting rod 5 has flanges at both ends that are connected to the active disk 3 and the driven disk 4. The connecting rod 5 fixes the active disk 3 and the driven disk 4 together and presses the activated carbon filter element 6 into place.

[0031] Both the active disk 3 and the driven disk 4 have multiple annular protrusions 7 on their opposing inner sides. The annular protrusions 7 are used to position and install the activated carbon filter element 6.

[0032] The drive shaft 8 is hollow inside, and a feed hole 14 is provided at the center of the drive disc 3. The feed hole 14 connects the inner cavity of the drive shaft 8 with the innermost cavity of the activated carbon filter element 6.

[0033] The drive shaft 8 is vertically inserted into the hollow motor 9 and the bearing housing 10. The hollow motor 9 is fixed to the cover plate 2 on the top of the housing 1, and provides power for the rotation of the drive shaft 8. The specific structure of the hollow motor 9 is prior art and will not be described in detail here.

[0034] The bearing seat 10 is fixedly connected to the support frame 11, and the support frame 11 is fixedly connected to the cover plate 2 on the top of the housing 1.

[0035] The top of the drive shaft 8 is connected to the feed pipe 13 via a rotary joint 12, and the feed pipe 13 can transport the material to be decolorized into the rotating drive shaft 8.

[0036] The driven shaft 15 is rotatably mounted inside the bracket 16, and the bracket 16 is fixed to the inner wall of the housing 1.

[0037] The bottom of the inner cavity of the shell 1 is provided with a discharge pipe, and a discharge valve 17 is installed on the pipe.

[0038] The specific working principle of this utility model is as follows:

[0039] The hollow motor 9 drives the drive shaft 8 to rotate, which in turn drives the multiple activated carbon filter elements 6 between the drive disk 3 and the driven disk 4 to rotate. At the same time, the succinic acid material to be decolorized is sequentially conveyed from the feed pipe 13 to the drive shaft 8 and the innermost activated carbon filter element 6. Under the action of centrifugal force, the material passes through each activated carbon filter element 6 in sequence, adsorbing the pigment in the material layer by layer. After decolorization, the material is collected at the bottom of the inner cavity of the shell 1 and finally discharged through the discharge valve 17.

[0040] The top of the active disc 3 is fixedly connected to the active shaft 8, and the bottom of the driven disc 4 is fixedly connected to the driven shaft 15. The active shaft 8 is rotatably installed in the bearing seat 10, and the driven shaft 15 is rotatably installed in the bracket 16. By rotating the active disc 3, activated carbon filter element 6 and driven disc 4 from both the top and bottom, the overall structure formed by the active disc 3, activated carbon filter element 6 and driven disc 4 remains stable during rotation.

[0041] By providing flanges at both ends of the connecting rod 5 that connect to the active disc 3 and the driven disc 4, the connecting rod 5 fixes the active disc 3 and the driven disc 4 together while pressing the activated carbon filter element 6, which facilitates the installation and subsequent replacement of the activated carbon filter element 6.

The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
