TECHNICAL FIELD

[0001] The utility model relates to filter equipment field, more specifically, it relates to a collagen solution's repeated filtration equipment. BACKGROUND

[0002] When collagen solution is used to prepare some products with extremely high purity requirements, such as high-precision biomedical reagents, key active ingredients in some high-end cosmetics, etc., even if the initial impurities are less, multiple filtrations (need to pass through different aperture filter screens to more comprehensively and thoroughly remove impurities of various particle sizes in the solution, improve the purity of the solution, but this also makes it difficult for a single device to repeatedly filter the collagen solution, so multiple filtrations are required). Because the performance and quality of these products are very sensitive to the purity of the solution, even trace amounts of impurities can affect the stability, efficacy or safety of the final product.

[0003] However, such multiple filtrations require the use of multiple pumps, multiple filter screens and multiple filter tanks (filtering in different tanks, then transferring to the next tank for the next step of filtration), which is very costly and occupies a lot of space. Moreover, when a single filter screen is clogged, it needs to be replaced, which seriously affects the filtration efficiency of the collagen solution. Therefore, the utility model provides a repeated filtration equipment for collagen solution.

[0004] Therefore, in order to solve the above technical problems, the present application provides a repeated filtration equipment for collagen solution. UTILITY MODEL CONTENT

DETAILED DESCRIPTION

[0024] As Figures 1-4 shown, the present application provides a repeated filtering equipment for collagen solution, which comprises an open-top filter tank 1, an outer side wall of the filter tank 1 is provided with a liquid outlet pipe 2 near the bottom, an opening part of the liquid outlet pipe 2 is provided with an electric three-way ball valve 3, two openings of the electric three-way ball valve 3 are connected with a liquid discharge pipe 4 and a circulating pipe 5 respectively, the liquid discharge pipe 4 and the circulating pipe 5 are both provided with a water pump 6, a rotating mechanism 8 for driving a plurality of filter screen assemblies 7 to rotate is installed beside the filter tank 1, so as to rotate the filter screen assemblies 7 to the top of the filter tank 1 in turn, at the same time, a water outlet part of the circulating pipe 5 is opposite to a top opening of the filter tank 1, the filter screen assembly 7 comprises an annular groove seat 701 and a metal filter screen 702 inside the annular groove seat 701.

[0025] In use, the first filter screen assembly 7 is rotated to the top of the filter tank 1 by the rotating mechanism 8, and the collagen solution is input from the top of the filter screen assembly 7, filtered by the metal filter screen 702 in the filter screen assembly 7, and then falls into the filter tank 1 due to gravity. At this time, the position of the valve core of the electric three-way ball valve 3 is switched by the controller, the liquid outlet pipe 2 is communicated with the circulating pipe 5, the water pump 6 on the circulating pipe 5 is opened, and the collagen solution is transported to the top of the filter screen assembly 7 again through the liquid outlet pipe 2 and the circulating pipe 5. Before this, different filter screen assemblies 7 are rotated to the top of the filter tank 1 in turn by the rotating mechanism 8 (it should be noted that the pore diameters of the metal filter screens 702 in different filter screen assemblies 7 are different). Thus, the solution can be repeatedly filtered by different filter screens. Compared with multiple filtering, the use of the pump and the tank is reduced, the cost is saved, and the space occupation is reduced. In addition, several filter screen assemblies 7 with the same metal filter screens 702 before and after can be arranged in the plurality of filter screen assemblies 7 as standby filter screen assemblies 7 (the metal filter screen 702 with a small pore diameter is prone to be blocked, and it is better to reserve a standby one). Thus, when the filter screen is blocked, the standby filter screen assembly 7 can be rotated to the top of the filter tank 1 immediately, and the blocked filter screen assembly 7 can be disassembled and processed, without the need to stop and replace, which is beneficial to improve the filtering efficiency of the collagen solution. After the filtering is completed, the position of the valve core of the electric three-way ball valve 3 is switched again by the controller, the liquid outlet pipe 2 is communicated with the liquid discharge pipe 4, the water pump 6 on the liquid outlet pipe 2 is opened, and the collagen solution in the filter tank 1 is discharged from the liquid discharge pipe 4 through the liquid outlet pipe 2, so that the collagen solution can be processed and processed in the next step.

The rotating mechanism 8 comprises a rotating rod 802 driven by a motor 801, and the outer side wall of the rotating rod 802 is fixedly connected with a connecting plate 803 around. The head of the connecting plate 803 is connected with the annular groove seat 701. That is, the rotation of the rotating rod 802 is driven by the motor 801, the connecting plate 803 is driven by the rotating rod 802, and the rotation of the filter screen assembly 7 is driven by the connecting plate 803. Thus, different filter screen assemblies 7 can be alternately rotated to the top of the filter tank 1.

[0027] In addition, the filter tank 1 and the bottom end of the base 9 are fixedly connected with the base 9. The top of the base 9 is further fixedly connected with a vertical plate 10. The head of the vertical plate 10 is fixedly connected with a bearing 11 for rotating and supporting the rotating rod 802. The rotating rod 802 is sleeved in the bearing 11 and is fixed with the inner ring part of the bearing 11. When the rotating rod 802 rotates, the inner ring of the bearing 11 rotates along the outer ring, so that the rotating rod 802 is rotatingly supported by the bearing 11, and the rotating rod 802 can stably rotate in the rated load range, so that the bending, deformation and damage of the rotating rod 802 due to excessive stress are avoided.

[0028] Further, the head of the connecting plate 803 is detachably connected with the annular groove seat 701 by screws, and the filter screen assembly 7 (including the annular groove seat 701) can be detached from the equipment by only detaching the screws; the top end of the base 9 is further provided with a backup power supply 12 for supplying power to the power-consuming components on the equipment when power is off, so as to ensure uninterrupted repeated filtration; in addition, the annular groove seat 701 is provided with a funnel 703 on each of the upper and lower sides, and the collagen solution can be shielded around by the upper and lower funnels 703, so as to avoid splashing when the collagen solution enters or exits the annular groove seat 701.
