Description

Technical Field

[0001] The utility model relates to a filtering device, in particular to a filtering device during the transmission of valine extraction liquid. Background Art

[0002] During the preparation of valine extraction liquid, valine is extracted from various natural food materials. Through specific extraction techniques, valine can be separated from these food materials and formed into valine extraction liquid through cultivation and fermentation.

[0003] When the valine fermentation broth is completed, in order to remove impurities, improve the purity and quality of the extraction liquid, and ensure the output of subsequent processing, it is necessary to filter the impurities in the fermentation broth to facilitate subsequent processing. Before filtration, the fermentation extraction liquid is transported through a pipeline. When the extraction liquid of the valine fermentation broth is transported to the next filtration station, since the extracted fermentation liquid contains a large amount of bacterial proteins, pigments, etc., there are many solid particles or viscous substances. These impurities will accumulate in the filtering device, resulting in blockage of the filtering device, thereby reducing the flux of the osmosis system in the filtering system, slowing down the passing speed of the filtrate, prolonging the filtering time of the post-treatment solution, and greatly affecting the filtering, processing and treatment efficiency of the extraction liquid.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1: A filtering device during the transmission of valine extract, as Figures 1-3 shown, including a shell 1, a liquid inlet joint 2, a liquid outlet joint 3, a filter cartridge 4, a filter membrane 5, a liquid outlet pipe 51 and a slag discharge pipe 6. The inside of the shell 1 is a sealed hollow setting. The left and right sides of the upper part of the shell 1 are respectively provided with a liquid inlet joint 2 and a liquid outlet joint 3. The liquid inlet joint 2 and the liquid outlet joint 3 are both communicated with the inside of the shell 1. The shell 1 is installed on the pipeline for transmitting valine extract through the liquid inlet joint 2 and the liquid outlet joint 3, so as to connect the liquid in the transmission pipeline into the shell 1. A slag discharge pipe 6 is provided on the right side of the lower part of the shell 1. The left part of the slag discharge pipe 6 penetrates into the inside of the shell 1 and is located between the filter cartridge 4 and the inner bottom of the shell 1;

[0024] Among them, as Figure 3 and Figure 5As shown in the figure, a filter cartridge 4 is provided inside the housing 1. The upper part of the filter cartridge 4 is fixedly connected to the upper part of the inner side of the housing 1. A number of notches are provided on the wall of the filter cartridge 4, and filter membranes 5 are arranged in the notches of the filter cartridge 4. A gap is left between the outer edge of the wall of the filter cartridge 4 and the inner wall of the housing 1. When the liquid enters the housing from the liquid inlet connector, the liquid in the housing will be blocked by the filter membrane 5 on the filter cartridge 4. At this time, impurities with larger particles will be blocked outside the filter cartridge 4, and the filtered liquid will enter the filter cartridge 4 through the pores of the filter membrane 5. A liquid outlet pipe 51 communicating with the liquid outlet connector 3 is arranged inside the filter cartridge 4, and the lower pipe orifice of the liquid outlet pipe 51 is located at the lower part of the inner side of the filter cartridge 4. A pump body should be arranged at one end of the infusion pipeline connected to the liquid outlet connector 3 to provide power for the liquid transmission. Start the pump body, and extract the filtered liquid in the filter cartridge 4 through the liquid outlet pipe 51 and transmit it outward. Through the filtering device installed on the valine extraction liquid conveying pipeline, the extraction liquid transmitted to the filtering station is preliminarily filtered, and bacteria, proteins, etc. with larger particles in the extraction liquid are blocked, which can reduce the maintenance frequency of subsequent filtering equipment blocked by large particle impurities, reduce the operation cost, and ensure the filtrate flux of the subsequent filtering station; after a period of time, the impurities blocked outside the filter cartridge 4 will be deposited at the lower part of the housing 1. Intermittently open the slag discharge pipe 6 to discharge the waste liquid containing slag in the housing 1.

[0025] Example 2: On the basis of Example 1, as Figures 1-4 shown, it further includes a separator 7, a liquid extraction pump 71 and a return pipe 72. A separator 7 for filtering and separating the waste liquid containing slag is provided on the slag discharge pipe 6. A liquid extraction pump 71 for extracting the liquid filtered by the separator 7 is installed at the rear of the separator 7. The input end of the liquid extraction pump 71 penetrates into the separator 7, and the output end of the liquid extraction pump 71 is connected with a return pipe 72. The upper part of the return pipe 72 penetrates into the housing 1. The liquid filtered and separated in the separator 7 is returned to the housing 1 through the liquid extraction pump 71 for secondary filtering, avoiding the loss caused by the valine mixed in the slag discharge waste liquid being discharged with the waste liquid, effectively reducing the loss of valine in the waste liquid, and ensuring the output of the extraction liquid.

[0026] In a specific embodiment: As Figures 1-3As shown in the figure, it further includes a cleaning pump 9, a clean water inlet pipe 91 and a backwash pipe 92. A cleaning pump 9 for online cleaning of the filter membrane 5 is installed on the top of the housing 1. The input end of the cleaning pump 9 is provided with a clean water inlet pipe 91 connected to an external clean water container, and the output end of the cleaning pump 9 is provided with a backwash pipe 92. The backwash pipe 92 vertically penetrates into the interior of the filter cartridge 4, and a number of liquid outlet fine holes are evenly opened on the backwash pipe 92. By providing the cleaning pump 9 and the backwash pipe 92, a backwashing mechanism is provided on the filtering device. During the filtering process, clean water is intermittently pumped into the filter cartridge 4 through the cleaning pump 9 and is ejected at a high speed through the liquid outlet fine holes of the backwash pipe 92, generating a large impact force to clean the impurities adhered to the filter cartridge 4 and the filter membrane 5 online. The clean water is directly discharged through the liquid outlet pipe 51 without stopping for maintenance, keeping the filter membrane 5 unobstructed, thereby maintaining the filtering effect and improving the stability of the device during use.

[0027] In a specific embodiment: As Figures 1-5 shown in the figure, it further includes an air inlet pipe 10. The air inlet pipe 10 connecting to an external high-pressure source penetrates through the lower part of the housing 1, and the upper part of the air inlet pipe 10 penetrates into the lower part of the filter cartridge 4. During filtration, liquid will seep into the filter cartridge 4. At this time, by connecting an external air source through the air inlet pipe 10, the gas discharged from the air inlet pipe 10 forms bubbles in the filtrate of the filter cartridge 4, causing the liquid in the filter cartridge 4 to flow crosswise. The flowing liquid impacts the filter membrane 5, causing the impurities adhered to the outside of the filter membrane 5 to fall off, effectively preventing the filter membrane 5 from being blocked and polluted.

[0028] In a specific embodiment: The filter membrane 5 is a flexible membrane with good anti-pollution performance. Compared with conventional rigid membranes, the flexible membrane can effectively solve the problem of membrane scaling, reduce the frequency of cleaning and maintenance. At the same time, during filtration, it has high strength and flexibility, and when used under high pressure, no additional energy consumption is required to maintain the structural integrity of the membrane.

[0029] In a specific embodiment: The lower part of the housing 1 is made of a transparent material that allows operators to directly observe the filtration process and the usage condition of the filter membrane 5. Through the transparent material, the filtration state and the pollution condition of the filter element can be observed, so as to judge whether it is necessary to replace and adjust components.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
