Description

Technical Field

[0001] The utility model belongs to the field of filtering devices, and in particular relates to a filtering and concentrating device for producing high-purity fish maw collagen small molecule peptides. Background Art

[0002] The collagen decomposition liquid (i.e., fish maw collagen peptide solution) produced by enzymatic hydrolysis using fish maw as raw material has different molecular weight distributions of collagen peptides. Currently, membrane separation is mostly used for purification to obtain the required collagen small molecule peptides. However, the membrane surface is easily contaminated and clogged by impurities during use, resulting in a decrease in membrane screening efficiency, a significant reduction in product purification speed, and a reduction in work efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a filtration and concentration device for producing high-purity fish maw collagen small molecule peptides, so as to solve the technical problem that most of the current methods use membrane separation to purify the required collagen small molecule peptides, but the membrane surface is easily contaminated and clogged by impurities during use, resulting in a decrease in membrane screening efficiency, a significant reduction in product purification speed, and a decrease in work efficiency.

[0004] To achieve the above-mentioned purpose, the specific technical scheme of the filtration and concentration device for producing high-purity fish maw collagen small molecule peptides in the utility model is as follows:

[0005] A filtering and concentrating device for producing high-purity fish maw collagen small molecule peptides, comprising a main shell; the main shell is cylindrical in shape and hollow inside; a tube shaft is rotatably arranged inside the main shell; the tube shaft is hollow; one end of the tube shaft extends to the outside of the main shell and is provided with a filtrate outlet; a plurality of disks are equidistantly arranged on the outside of the tube shaft; filter membranes are provided on both sides of the disks; a plurality of connecting holes are provided in the disks and communicate with the inside of the tube shaft; a liquid inlet is provided on the upper part of one side of the main shell; a liquid outlet is provided on the side of the main shell away from the liquid inlet; and a solution to be filtered is pressurized and introduced into the main shell through the liquid inlet.

[0006] Furthermore, the end of the tube axis away from the filtrate outlet is sealed.

[0007] Furthermore, one end of the tube shaft relative to the filtrate outlet extends to the outside of the main shell and is connected to a driving shaft.

[0008] Furthermore, the diameter of the disc is smaller than the inner diameter of the main shell.

[0009] Furthermore, the disc is provided with an elastic support on the inner side of the filter membrane.

[0010] The utility model discloses a filtering and concentrating device for producing high-purity fish maw collagen small molecule peptides, which has the following advantages: by arranging filter membranes on both sides of the disc, during the process of filtering the solution to be filtered, the filter membranes on both sides of the disc filter the solution to be filtered at the same time, and the filtration efficiency is high. Compared with the commonly used single membrane filtration, the double-sided filter membrane structure of the disc provides twice the filter membrane area in the same unit volume, and can contact with more solutions at the same time, thereby increasing the filtration efficiency; the tube axis is driven to rotate by the driving shaft, and the multiple discs rotate with the tube axis at the same time. During the rotation of the disc, the filter membranes arranged on both sides thereof perform filtering work at the same time, and the impurities filtered out from the surface of the filter membrane are thrown outward by the centrifugal force brought by the rotation of the disc, and then separated from the filter membrane and the disc, and cannot be blocked and adhered to the surface of the filter membrane, thereby avoiding the filter membrane being blocked by impurities, so that the membrane flux is not attenuated, improving the stability of continuous filtration, and increasing the overall filtration efficiency of the device during long-term use.

[0015] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of the filtration and concentration device for producing high-purity fish maw collagen small molecule peptides in conjunction with the accompanying drawings.

[0016] like Figure 1-3 As shown, the utility model is a filtering and concentrating device for producing high-purity fish maw collagen small molecule peptides, comprising a main shell 1; the main shell 1 is cylindrical in shape and hollow inside; a tube shaft 2 is rotatably arranged in the main shell 1; the tube shaft 2 is hollow; one end of the tube shaft 2 extends to the outside of the main shell 1 and is provided with a filtrate outlet 3; a plurality of disks 4 are equidistantly arranged on the outside of the tube shaft 2; filter membranes 5 are provided on both sides of the disk 4; a plurality of connecting holes 6 are provided in the disk 4 and are connected to the inside of the tube shaft 2; a liquid inlet 7 is provided on the upper part of one side of the main shell 1; a liquid outlet 8 is provided on one side of the main shell 1 away from the liquid inlet 7; the solution to be filtered is pressurized and introduced into the main shell 1 through the liquid inlet 7, and the diameter of the disk 4 is smaller than the inner diameter of the main shell 1.

[0017] Combine Figure 1-3 As shown, when in use, the collagen decomposition liquid to be filtered produced by enzymatic hydrolysis (i.e., fish maw collagen peptide solution) is introduced into the main shell 1 from the liquid inlet 7 through external pressurization, and the main shell 1 is filled with the solution to be filtered. The solution to be filtered contacts the filter membrane 5 set on the disc 4, and the required collagen small molecule peptide passes through the filter membrane 5 and reaches the disc 4, and then enters the tube shaft 2 through the connecting hole 6, and is finally discharged from the filtrate outlet 3 of the tube shaft 2. The filtered solution can be discharged from the main shell 1 through the liquid outlet 8. In the process of filtering the solution, the filter membranes 5 on both sides of the disc 4 simultaneously filter the contacted solution to be filtered, and the filtration efficiency is high. Compared with the commonly used single membrane filtration, the double-sided filter membrane 5 structure of the disc 4 provides twice the filter membrane 5 area in the same unit volume, and can contact with more solutions at the same time, thereby increasing the filtration efficiency.

[0018] The end of the tube shaft 2 away from the filtrate outlet 3 is sealed, and the end of the tube shaft 2 relative to the filtrate outlet 3 extends to the outside of the main shell 1 and is connected to a driving shaft 9. The tube shaft 2 is driven to rotate by the driving shaft 9, and multiple discs 4 rotate with the tube shaft 2. During the rotation of the disc 4, the filter membranes 5 arranged on both sides thereof perform filtering work at the same time, and the impurities filtered out of the surface of the filter membrane 5 are thrown to the outside by the centrifugal force brought about by the rotation of the disc 4, and then separated from the filter membrane 5 and the disc 4, and cannot be blocked or adhered to the surface of the filter membrane 5, thereby avoiding the filter membrane 5 being blocked by impurities, preventing the membrane flux from attenuating, improving the stability of continuous filtration, and increasing the overall filtration efficiency of the device during long-term use. It can also reduce the cleaning of the surface of the filter membrane 5 and reduce the workload.

[0019] The disc 4 is provided with an elastic support 10 on the inner side of the filter membrane 5. In order to increase the filtration efficiency of the filter membrane 5, the solution to be filtered will be pressurized during the process of being introduced through the liquid inlet 7, so that the required collagen small molecule peptides in the solution can pass through the filter membrane 5 faster, thereby increasing the filtration efficiency. The pressurized solution will exert a greater pressure on the filter membrane 5. The elastic support 10 can form a support for the filter membrane 5 to prevent the filter membrane 5 from being damaged by the pressure of the larger solution.

Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention.
