Description

Technical Field

[0001] The utility model relates to the field of chitosan oligosaccharide production, in particular to a purification device for chitosan oligosaccharide production. Background Art

[0002] Chitosan oligosaccharide is the only alkaline polysaccharide with positive charge in nature, with good water solubility and biological activity; it has a low molecular weight, a water solubility greater than 99%, and a human absorption rate of nearly 100%, so it is widely used in the medical field (chitosan oligosaccharide has significant effects in improving immunity, inhibiting cancer cell growth, and promoting mineral absorption), the agricultural field (chitosan oligosaccharide as a plant growth regulator can promote plant growth) and the food field (chitosan oligosaccharide as a food additive); the production process of chitosan oligosaccharide includes raw material decapping, deproteinization, decolorization and enzymatic hydrolysis. After the enzymatic hydrolysis process is completed, the corresponding chitosan oligosaccharide stock solution will be generated. In order to improve the purity of chitosan oligosaccharide, after the enzymatic hydrolysis is completed, corresponding purification equipment is usually required to filter out impurities in the stock solution.

[0003] The commonly used filtration methods are divided into activated carbon adsorption, ultrafiltration and chromatography, among which ultrafiltration is the most widely used. People usually add chitosan oligosaccharide stock solution to the filter device inside the purification tank, and filter impurities through the ultrafiltration membrane on the outer wall of the filter device. In order to ensure the activity of the chitosan oligosaccharide stock solution, the stirring shaft of the stirring device is usually used to continuously stir the chitosan oligosaccharide stock solution in the filter device to prevent impurities from clogging the filter holes, while ensuring the activity of the stock solution and preventing the stock solution from solidifying in the filter device. Finally, the finished chitosan oligosaccharide will flow out from the discharge port at the bottom of the purification tank.

[0004] Although the existing purification device can effectively filter out impurities in the chitosan oligosaccharide stock solution, the impurities in the filter device are difficult to discharge. In order to ensure its stability, the filter device is usually fixed on the purification tank, and because the stirring shaft of the stirring device is directly inserted into the bottom surface of the filter device, this makes the cleaning of the filter device extremely difficult. If you want to remove the filter device, you must disassemble the stirring device. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the filtering device of the existing purification device for chitosan oligosaccharide production is difficult to be directly disassembled and cleaned after the purification is completed.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: a purification device for chitosan oligosaccharide production, comprising a purification tank, a filtering device is provided inside the purification tank, a stirring device is provided on one side of the filtering device, the stirring device comprises a stirring shaft and a driving motor for driving the stirring shaft, the filtering device is a detachable structure, a height adjustment device is provided on one side of the stirring device for controlling the height of the stirring device, the height adjustment device comprises a detachable T-shaped discharge pipe at the outer wall end of the stirring shaft and several telescopic devices located below the thick column end of the T-shaped discharge pipe, the thin column end of the T-shaped discharge pipe passes through the top shell cover of the purification tank, the stirring shaft passes through the thick cylindrical surface of the T-shaped discharge pipe, and a replacement door is provided on one side of the purification tank.

[0007] As an improvement, the thin cylindrical end of the T-shaped discharge pipe is connected to the central through hole of the top shell cover of the purification tank through an anti-wear gasket, and the stirring shaft is connected to the central through hole of the thick cylindrical surface of the T-shaped discharge pipe through a bearing.

[0008] As an improvement, the bottom surface of the telescopic device and the top shell cover of the purification tank, the output shaft of the telescopic device and the drive motor are connected to both sides of the thick column end of the T-shaped discharge pipe through a bolt structure.

[0009] As an improvement, the filtering device includes a material storage tank and a filter membrane attached to the side of the material storage tank, and the side of the material storage tank is provided with a plurality of filter holes.

[0010] As an improvement, the interior of the purification tank is provided with a material trough fixing frame located at the bottom surface of the material storage trough, and the interior of the material trough fixing frame is provided with a polygonal limiting column, and the polygonal limiting column passes through the bottom surface of the material storage trough.

[0011] As an improvement, the storage trough and the inner wall of the purification tank cavity are connected to the trough fixing frame through a bolt structure.

[0012] As an improvement, a fixed support frame is provided below the purification tank, and a stop valve is provided on one side of the discharge port below the purification tank.

[0013] As an improvement, a feed port is provided on one side of the thin column end of the T-shaped discharge pipe.

[0014] The advantages of the present invention over the prior art are that the fixing device of the stirring device is set as a height-adjustable fixing device, so that after the processing of the filtering device is completed, the relative position of the stirring shaft and the filtering device can be changed by simply adjusting the telescopic degree of the telescopic device. This makes the disassembly of the filtering device unaffected by the stirring shaft, and facilitates the disassembly of the filtering device. In order to facilitate the removal and placement of the filtering device, a corresponding replacement door is opened on the side wall of the purification tank to facilitate the replacement of the filtering device.
