Description

Technical Field

[0001] The utility model relates to the field of yeast separation, in particular to a filtering and cleaning device in a yeast separation system. Background Art

[0002] Yeast separators are widely used in industries such as beer brewing, fermentation, and food processing, primarily to separate yeast cells from liquids. In these applications, yeast solutions often contain large amounts of solid particles and impurities, which can easily clog the nozzles during the separation process, affecting both the separation efficiency and the proper functioning of the equipment.

[0003] Existing yeast separators are prone to nozzle clogging during use. The main reasons are as follows: Liquid impurities: Yeast solutions often contain large amounts of solid particles, fibers, proteins, and other impurities, which can easily accumulate as they pass through the nozzle, leading to nozzle clogging. Fluid characteristics: Highly viscous or easily solidifying liquids tend to form a gel-like substance at low temperatures, further exacerbating nozzle clogging. Operating conditions: Long-term continuous operation and improper cleaning and maintenance can also increase the risk of nozzle clogging. Utility Model Content

[0026] like Figures 1-3 As shown, a filtering and cleaning device in a yeast separation system includes a yeast tank 1, a delivery pump 2 and a yeast separator 3. The delivery pump 2 is connected to the yeast tank 1 and the yeast separator 3 through a pipeline. The pipeline between the delivery pump 2 and the yeast separator 3 is at least two parallel delivery branches 4.

[0027] Two control valves 5 are provided on the delivery branch pipe 4, and a filter tube 6 and a cleaning tube 8 are provided between the two control valves 5. A filter cartridge 10 is fixed in the filter tube 6, and a flushing tube 12 at the end of the cleaning tube 8 is located inside the filter tube 6 for backwashing the filter tube 6 from inside the filter tube 6.

[0028] At least two parallel delivery branches 4 can be used in a backup mode. When the active filter cartridge 10 is seriously clogged and needs to be cleaned or replaced, the backup delivery branch 4 is switched to, and high-pressure cleaning liquid is introduced into the clogged filter cartridge 10 to flush the inside of the filter cartridge 10, flushing impurities attached to the outside of the filter cartridge 10 and emptying them, thereby extending the service life of the filter cartridge 10.

[0029] Normal operating mode: Yeast solution is transferred from yeast tank 1 to yeast separator 3 via transfer pump 2. The pipelines between transfer pump 2 and yeast separator 3 are at least two parallel delivery branches 4. Each delivery branch 4 is equipped with two control valves 5, one of which is in operation and the other in standby mode. A filter cartridge 10 within filter tube 6 on the active delivery branch 4 filters the yeast solution.

[0030] Cleaning Mode: When the active filter cartridge 10 becomes severely clogged and requires cleaning or replacement, control valve 5 switches to the standby delivery branch 4. After this switch, the clogged filter cartridge 10 ceases operation, and the standby filter cartridge 10 begins operation. High-pressure cleaning fluid is introduced into the clogged filter cartridge 10, backwashing it from within the filter tube 6 via the cleaning pipe 8 and flushing pipe 12. This backwashing process removes impurities adhering to the exterior of the filter cartridge 10 and discharges them from the system through the drain pipe. Once cleaned, the filter cartridge can be put back into service or replaced.

[0031] The one-for-one backup design ensures continuous system operation, preventing the entire production process from being interrupted by a single filter cartridge blockage. The backwash design effectively removes impurities from the filter cartridge 10, extending its service life. By switching the control valve 5, the filter cartridge can be easily cleaned or replaced, reducing maintenance time and costs. Regular cleaning and maintenance effectively extend the service life of the filter cartridge 10 and other equipment.

[0032] Preferably, a reversing valve is provided between both ends of the delivery branch pipe 4 and the main pipe to control the flow direction of the liquid. The reversing valve switches different pipelines to ensure the continuity of the process.

[0033] Preferably, a dirt collecting barrel 9 is fixed at the bottom of the front end of the filter tube 6, and a cover is fixed at the outlet of the bottom of the dirt collecting barrel 9. The dirt collecting barrel 9 is arranged at the front end to collect the impurities filtered out, and the impurities washed down by backwashing are also concentrated in the dirt collecting barrel 9. The impurities can be emptied by opening the cover.

[0034] Preferably, a connecting pipe 7 is provided between the tail end of the filter tube 6 and the control valve 5, a fixing ring 13 is fixed to the end of the filter cartridge 10, and the fixing ring 13 is sealed and fixed between the filter tube 6 and the connecting pipe 7 by flanges and bolts, and the cleaning pipe 8 is fixed in the connecting pipe 7. The filter tube 6, the fixing ring 13 and the connecting pipe 7 are fixedly connected by flanges and bolts. The U-shaped filter component of the filter cartridge 10 and the fixing ring 13 at the end, the filter component, constitute the support member and the filter layer, and the support member can support the filter layer. The flushing pipe 12 at the end of the cleaning pipe 8 is located inside the filter cartridge 10 and can backwash the filter layer to extend its service life.

[0035] Preferably, one end of the cleaning pipe 8 passes through one side of the connecting pipe 7 and is fixedly connected, and the flushing pipe 12 at the other end is coaxially arranged with the connecting pipe 7.

[0036] A positioning ring 11 is provided between the outside of the flushing pipe 12 and the connecting pipe 7 , and the positioning ring 11 is used to fix the flushing pipe 12 and the connecting pipe 7 so that they are coaxially arranged.

[0037] The cleaning pipe 8 is connected to the pump and the water tank through a pipeline. The cleaning liquid in the water tank is compressed and transported to the flushing pipe 12 by pumping and sprayed out, thereby flushing the filter cartridge 10.

[0038] One end of the cleaning pipe 8 passes through one side of the connecting pipe 7 and is fixedly connected to ensure the stability of the connection. The flushing pipe 12 at the other end is coaxially arranged with the connecting pipe 7 to ensure that the injection direction of the cleaning liquid is accurate.

[0039] The flushing pipe 12 is located inside the filter tube 6, coaxially arranged with the connecting pipe 7, and fixed by a positioning ring 11. The nozzle design of the flushing pipe 12 should ensure that the cleaning liquid can be evenly sprayed into the interior of the filter cartridge 10 to improve the cleaning effect.

[0040] The positioning ring 11 is arranged between the outside of the flushing pipe 12 and the connecting pipe 7 to ensure that the flushing pipe 12 and the connecting pipe 7 are coaxially arranged and prevent the flushing pipe 12 from deviating.

[0041] The pump and water tank provide cleaning liquid, which is compressed and pumped to the flushing pipe 12 for spraying. The selection of the pump should take into account the flow rate and pressure requirements to ensure that the cleaning liquid can effectively flush the filter cartridge 10.

[0042] The backwash design effectively removes impurities from the filter cartridge 10, extending its service life. The locating ring 11 ensures that the flushing pipe 12 is coaxial with the connecting pipe 7, enhancing cleaning efficiency. Impurities are collected in the collection canister 9 and can be emptied by opening the cover, making operation simple and convenient. The two-in-one backup design ensures continuous system operation, preventing the entire production process from being interrupted by a single filter cartridge blockage. Regular cleaning and maintenance effectively extend the service life of the filter cartridge 10 and other equipment.
