[0002] Liquid separation devices play a key role in the fermentation tanks of biochemical engineering. They are used to remove impurities and microorganisms in the fermentation liquid, purify the target product, ensure the stability and efficiency of the fermentation process, and promote the smooth progress of downstream processing procedures. They are an important technical means to improve the quality and output of biochemical products.

[0003] The existing separation device for fermentation liquid, in pursuit of maximum production efficiency, poses significant challenges to its core component, the filtration mechanism. As the separation operation continues, impurities and particles in the liquid will gradually accumulate at the filter holes, causing the filter holes to gradually become clogged. Frequent shutdowns for cleaning not only interrupt the production process, but also increase operating costs.

[0004] The existing continuous liquid separation device operates uninterruptedly, which causes the filter holes of the filter separation mechanism to be clogged and difficult to clean, affecting the efficiency of continuous liquid separation and the reliability of long-term separation operations.

[0055] When in use, under the operation of the horizontal screw rod 32, the high pressure generated at the other end of the horizontal tank 31 is partially received by the booster tank 5, and after the overall device has been running for a period of time, the first shut-off valve 42 is temporarily closed, and the second shut-off valve 54 is randomly opened to allow the high pressure to quickly enter the jacket 21. Due to the effect of the previous negative pressure, two pressure environments are formed inside and outside the stainless steel conical filter sleeve 22. After the high-pressure air enters, after the high-pressure air enters the jacket 21, this pressure difference will quickly act on the fermentation material in the filter holes of the stainless steel conical filter sleeve 22, forcing them to quickly return to the stainless steel conical filter sleeve 22, realizing a recoil effect, so that the blockages in the filter holes of the stainless steel conical filter sleeve 22 are cleared, thereby maintaining its good filtering performance and extending its service life.

[0056] like Figure 1-6 As shown, the present invention also includes that a commutator 7 is installed on the top of the sealing cover 201, the output end of the commutator 7 is connected to the shaft head of the main shaft 29, and a transmission shaft 8 is installed on the output end of the commutator 7, and the transmission shaft 8 is arranged on the sealing cover 201 through a bearing seat;

[0057] The driving mechanism includes a driving motor 6 and a transmission 61, and the driving motor 6 and the transmission 61 are installed on one side of the equipment frame 1, the input end of the driving motor 6 is connected to the shaft head of the transmission shaft 8 through a coupling, and the output end of the driving motor 6 is connected to the input end of the driving motor 6.

[0060] When the present invention is in use, the present application is assembled on the fermentation tank operation site of the biochemical industry, and the power supply components around the site provide power for the electrical mechanism in the present application. During assembly, the discharge end of the fermentation tank is connected to the rotary joint 2111 through a pipeline, and then the liquid discharge joint 41 and the solid discharge joint 214 are respectively connected to the pipelines and containers of the lower fermentation liquid and fermentation solid in the operation site. At the same time, the electrical components in the present application are connected to the central control host in the operation site, and the central control host in the operation site uniformly coordinates and controls the electrical appliances in the present application. During operation, the drive motor 6 works, and the drive motor 6 transmits the driving force to the transmission 61, and the transmission 61 transmits the driving force to the transmission shaft 8, and the transmission shaft 8 transmits the power to the commutator 7 and the lower sprocket 9 respectively. The commutator 7 drives the core sleeve 25 and the stainless steel conical filter sleeve 22 to rotate based on the main shaft 29, and the lower sprocket 9 transmits the transmission to the upper sprocket 36 of the horizontal screw rod 32 through the transmission chain. The discharge end of the fermentation tank sends the fermentation material from the feed conduit 212 to the inner bottom of the stainless steel conical filter sleeve 22 through the rotary joint 2111. Based on the centrifugal force generated by the stainless steel conical filter sleeve 22 under high-speed rotation, the liquid in the fermentation material passes through the filter holes of the stainless steel conical filter sleeve 22 into the jacket 21, and enters the negative pressure tank 4 through the first one-way valve 215. The fermentation liquid is pumped away by the next processing procedure of the fermentation liquid in the work site through the drainage joint 41 at the bottom of the negative pressure tank 4. At the same time, the conical structure of the stainless steel conical filter sleeve 22 and the first spiral blade 26 are used to pump the fermentation material away from the bottom of the negative pressure tank 4. Under the rotating centrifugal force in the stainless steel conical filter sleeve 22, the conical structure of the stainless steel conical filter sleeve 22 and the first spiral blade 26 will make the solid material in the fermentation material move upward continuously, so that the solid material gradually enters the core sleeve 25, and with the help of the second spiral blade 27 set in the opposite direction in the core sleeve 25, the fermentation solid material entering the core sleeve 25 is guided downward by the second spiral blade 27, and the solid material is thrown out to the bottom of the jacket 21 through the solid discharge port 210 below the core sleeve 25, so as to realize the active discharge of the solid material in the fermentation material, and the fermentation solid material continuously discharged from the core sleeve 25 can enter the solid discharge joint 214 through the discharge port 213, and be discharged to the outside through the solid discharge joint 214, so that the fermentation solid material after liquid filtration is discharged independently. During this period, the solid discharge joint 214 can be equipped with a discharge valve, and the solid discharge joint 2 14 can be directly connected to the solid material collection container for discharge, or the solid material can be discharged to the next processing process through a discharge pipe such as an auger. The driving force of the driving mechanism causes the horizontal screw rod 32 to rotate synchronously. The rotating horizontal screw rod 32 continuously pushes the air at one end of the horizontal tank 31 to the other end of the horizontal tank 31, so that a negative pressure is formed at one end of the horizontal tank 31, and a high pressure is formed at the other end of the horizontal tank 31. The negative pressure end of the horizontal tank 31 evacuates the negative pressure tank 4 through the air inlet joint 33 and the exhaust joint 43, so that a negative pressure state is formed between the jacket 21 and the stainless steel conical filter sleeve 22, so that the liquid in the fermented material rotating centrifugally in the stainless steel conical filter sleeve 22 can be separated from the fermented solid material more quickly, effectively improving the efficiency of liquid separation. Under the operation of the horizontal screw rod 32,After the high pressure is generated at the other end of the horizontal tank 31, the high-pressure air in the horizontal tank 31 is transported to the three-way reversing valve 51 through the air outlet joint 34, and the three-way reversing valve 51 sends the high-pressure air to the boosting tank 5. During this period, the air pressure in the boosting tank 5 is detected by the pressure sensor 52. After the air pressure in the boosting tank 5 exceeds the set value, the three-way reversing valve 51 cuts off the air supply to the boosting tank 5 and discharges the air to the exhaust gas treatment pipeline in the work site. After the overall device has been running for a period of time, the first shut-off valve 42 is temporarily closed and the first shut-off valve 42 is randomly opened. The second shut-off valve 54 is opened to allow high pressure to quickly enter the jacket 21. Due to the effect of the negative pressure in the early stage, two pressure environments are formed inside and outside the stainless steel conical filter sleeve 22. After the high-pressure air enters, this pressure difference will quickly act on the fermented materials in the filter holes of the stainless steel conical filter sleeve 22, forcing them to quickly return to the stainless steel conical filter sleeve 22, realizing the backwash effect, so that the blockages in the filter holes of the stainless steel conical filter sleeve 22 are cleared, thereby maintaining its good filtering performance and extending its service life;

[0061] Among them, the frequency of the recoil movement is set according to actual usage requirements.
