Description

[0002] Liquor yellow water is a brown-yellow, slightly viscous liquid produced during the solid-state fermentation of liquor. It is an important by-product of the liquor fermentation process and has an important impact on the quality and flavor of the liquor. The state and composition changes of yellow water can also reflect whether the fermentation process is normal, and provide an important reference for the adjustment and optimization of the liquor production process.

DETAILED DESCRIPTION

[0020] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples of the specification. The following examples are only used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figure 1-Figure 8 As shown, this embodiment proposes a device and method for extracting yellow slurry water from solid-state fermentation of liquor, comprising an extraction mechanism 1, a filtering mechanism 2 is arranged in the middle of the extraction mechanism 1, and sweeping mechanisms 3 are evenly distributed on the inner periphery of the filtering mechanism 2; The filtering mechanism 2 includes an inner pump shell 21 and a limiting ring 214. The outer periphery of the inner pump shell 21 is evenly distributed with liquid outlets 22. The inner two sides of the liquid outlet 22 are rotatably connected to one end close to the inner pump shell 21, and a spring 24 is evenly distributed on the side of the blocking door 23 away from the inner pump shell 21. The ends of the two sides of the blocking door 23 away from the inner pump shell 21 are fixedly connected with scraping grooves 25, and the lower ends of the scraping grooves 25 are connected with collecting pipes 26. The outer periphery of the inner pump shell 21 is rotatably connected to a filter net shell 215, and the outer periphery of the lower end of the filter net shell 215 is fixedly connected with a gear ring 29, and the gear ring 29 is meshingly connected with a gear 210. The inside of the gear 210 is fixedly connected with a driving column 211, and driving grooves 212 are provided on both sides of the outside of the driving column 211. The inside of the driving groove 212 is slidably connected with limiting beads 213, and the outer periphery of the limiting beads 213 is rotatably connected to the middle parts of the inner two sides of the limiting ring 214.

[0022] In this embodiment, the collecting ports 27 are evenly distributed at the lower end of the filter mesh shell 215, and the inner bottom wall of the outer pump shell 11 is fixedly connected with a sewage collecting pipe 28.

[0023] In this embodiment, the ends of the spring 24 away from the baffle 23 are fixedly connected to the inner sides of the liquid outlet 22, the lower ends of the collecting tubes 26 are connected to the interior of the collecting port 27, and the upper ends of the extraction tubes 5 are connected to the interior of the inner pump casing 21.

[0024] In this embodiment, the lower ends of the limiting beads 213 are rotatably connected to the left side of the inner bottom wall of the outer pump housing 11 , and the outer periphery of the limiting ring 214 is fixedly connected to the inner bottom of the left opening at the lower end of the piston bowl 12 .

[0025] Specifically, when it is necessary to extract yellow slurry water, the electric push rod 16 is started, and the piston bowl 12 is driven to move upward through the cross bar 15 and the piston column 14. At this time, the cross bar 15 and the one-way valve at the lower end of the exhaust pipe 8 are opened, and the one-way valve inside the liquid outlet pipe 6 and the sewage pipe 7 are closed. The yellow slurry water inside the yellow slurry pool inside the fermentation tank is extracted into the inner pump shell 21 through the extraction pipe 5. At this time, the internal pressure of the inner pump shell 21 increases, so that the baffles 23 on both sides of the liquid outlet 22 are opened, and the yellow slurry water flows into the inside of the baffles 23, and enters the inner lower part of the outer pump shell 11 after being filtered by the filter mesh shell 215. When the piston bowl 12 descends, the cross bar 15 and the one-way valve at the lower end of the exhaust pipe 8 are closed, and the one-way valve inside the liquid outlet pipe 6 and the sewage pipe 7 are opened. The filtered yellow slurry water is discharged from the liquid outlet pipe 6, completing the filtration and extraction of the yellow slurry water.

[0026] In this embodiment, an extraction tube 5 is fixedly connected to the opening in the middle of the lower end of the extraction mechanism 1, a liquid outlet tube 6 is fixedly connected to the opening in the front lower end of the extraction mechanism 1, a sewage discharge pipe 7 is fixedly connected to the opening in the right middle of the lower end of the extraction mechanism 1, and an exhaust pipe 8 is fixedly connected to the opening in the front side of the upper end of the extraction mechanism 1.

[0027] In this embodiment, a base 4 is fixedly connected to the outer periphery of the lower end of the extraction mechanism 1, and a one-way valve is fixedly connected to the inside of the end of the extraction tube 5 away from the extraction mechanism 1 and the liquid outlet pipe 6, the sewage pipe 7 and the exhaust pipe 8 close to the extraction mechanism 1.

[0028] In this embodiment, the extraction mechanism 1 includes an outer pump shell 11, and the inner upper part of the outer pump shell 11 is slidably connected to a piston bowl 12, and the middle part of the upper end of the piston bowl 12 is fixedly connected to a piston column 14, and the upper end of the piston column 14 is fixedly connected to a cross bar 15, and both ends of the cross bar 15 are fixedly connected to electric push rods 16, and the outer periphery of the electric push rods 16 are fixedly connected to the upper ends of both sides of the outer pump shell 11, and the right side of the inner bottom wall of the outer pump shell 11 is fixedly connected to a limiting column 13, and the upper end outer periphery of the limiting column 13 is slidably connected to the right lower end opening of the piston bowl 12.

[0029] Specifically, when the piston bowl 12 descends, the limiting bead 213 slides in the inclined groove of the driving groove 212, and the limiting ring 214 drives the driving column 211 to rotate through the limiting bead 213 and the driving groove 212, and then drives the filter screen housing 215 to rotate through the gear 1 210 and the gear ring 29, so that the clean part of the filter screen housing 215 continues to rotate to the opening periphery of the liquid outlet 22, and the part of the filter screen housing 215 that has filtered the yellow slurry water rotates toward the sweeping mechanism 3. At the same time, the sludge residue on the inner periphery of the filter screen housing 215 is scraped off through the scraping groove 25 and falls to the inner lower part of the liquid outlet 22. The part is moved upward, and at the same time, the baffle door 23 is closed by a spring 24. The scraped sludge residue will be discharged into the interior of the sewage collecting pipe 28 through the collecting pipe 26 and the collecting port 27 due to the internal pressurization of the outer pump housing 11, and discharged through the sewage discharge pipe 7. When the piston bowl 12 rises, the limiting bead 213 slides in the straight groove of the driving groove 212, so that when the piston bowl 12 rises, the yellow slurry water can always be effectively filtered, and the filtration effect will not be deteriorated due to excessive sludge residue remaining in the filter mesh housing 215, thereby reducing the efficiency of extracting yellow slurry water.

[0030] In this embodiment, the sweeping mechanism 3 includes a rotating shaft 31 and a pull rod 310. There are eight rotating shafts 31, which are alternately distributed on the outer periphery of the inner pump housing 21 with the liquid outlet 22. The outer periphery of the rotating shaft 31 is fixedly connected with a sweeping roller 32, and the middle outer periphery of the sweeping roller 32 is rotatably connected with the pull rod 310. Both ends of the rotating shaft 31 are fixedly connected with a mounting ring 33, and ratchets 34 are evenly distributed inside the mounting ring 33. Both ends of the ratchet 34 on the side close to the rotating shaft 31 are fixedly connected with springs 2 35. The outer periphery of the mounting ring 33 is rotatably connected with gear 2 36, and ratchet teeth 37 are evenly distributed inside the gear 2 36. Gear 2 36 is meshed with racks 38, and both ends of the ratchet teeth 37 are slidably connected to the inside of the slide groove 39.

[0031] In this embodiment, the upper end of the pull rod 310 is fixedly connected to the outer periphery of the inner top wall of the piston bowl 12, and the end of the spring 35 close to the rotating shaft 31 is fixedly connected to the inside of the mounting ring 33.

[0032] In this embodiment, the rack 38 and the side of the slide groove 39 away from the rotating shaft 31 are fixedly connected to the two sides of the liquid outlet 22, and the ratchet pawls 34 are matched with the ratchet teeth 37.

[0033] Specifically, when the piston bowl 12 descends, the piston bowl 12 drives the rotating shaft 31 to descend through the sweeping roller 32, and the pawl 34 cooperates with the ratchet 37, so that the gear 2 36 drives the pawl 34 to rotate through the rack 38, and then drives the sweeping roller 32 to rotate through the rotating shaft 31, continuously sweeping and hooking the inside of the mesh of the filter screen shell 215, and dropping it into the inside of the collecting port 27, and then discharged through the sewage collecting pipe 28 and the sewage discharge pipe 7. When the piston bowl 12 rises, the pawl 34 and the ratchet 37 disengage and engage, so that the sweeping roller 32 will not reverse during the rising process, thereby avoiding the sludge residue remaining on the outside of the sweeping roller 32 from being thrown back into the mesh of the filter screen shell 215 due to centrifugal force, thereby achieving that in the process of extracting yellow slurry water, the mesh of the filter screen shell 215 can be continuously cleaned, further improving the filtering effect of the extracted yellow slurry water, completing the self-cleaning of the filter screen shell 215, and reducing the maintenance cost and frequency of the equipment.

[0034] A method for extracting yellow slurry water from solid-state fermentation of liquor, applied to any one of the above-mentioned yellow slurry water extraction devices for solid-state fermentation of liquor, characterized in that it comprises the following steps: S1. First, the electric push rod 16 is started to drive the piston bowl 12 to rise, the one-way valves at the lower ends of the extraction pipe 5 and the exhaust pipe 8 are opened, and the interior of the outer pump housing 11 is in a negative pressure state. The yellow slurry water is extracted from the extraction pipe 5 to the interior of the filter mechanism 2 for filtration, and then falls to the inner lower part of the outer pump housing 11; S2. When the piston bowl 12 descends, the one-way valves at the upper ends of the sewage pipe 7 and the liquid outlet pipe 6 are opened, and the filtered yellow slurry water is discharged and collected from the liquid outlet pipe 6. The filter mesh shell 215 rotates, and the sludge residue inside is scraped off by the scraping groove 25 and collected into the sewage collecting pipe 28. At the same time, the sweeping roller 32 moves downward and rotates to scrape off the sludge residue remaining inside the mesh of the filter mesh shell 215, and hooks it out, and enters the sewage collecting pipe 28 through the collecting port 27, and finally discharges the sludge residue through the sewage pipe 7.

[0035] Working principle: when it is necessary to extract yellow slurry water, start the electric push rod 16, and drive the piston bowl 12 to move upward through the cross bar 15 and the piston column 14. At this time, the cross bar 15 and the one-way valve at the lower end of the exhaust pipe 8 are opened, and the one-way valve inside the liquid outlet pipe 6 and the sewage pipe 7 are closed. The yellow slurry water inside the yellow slurry pool inside the fermentation tank is extracted into the inner pump shell 21 through the extraction pipe 5. At this time, the internal pressure of the inner pump shell 21 increases, so that the baffles 23 on both sides of the liquid outlet 22 are opened, and the yellow slurry water flows into the inside of the baffles 23, and enters the inner lower part of the outer pump shell 11 after being filtered by the filter mesh shell 215. When the piston bowl 12 descends, the cross bar 15 and the one-way valve at the lower end of the exhaust pipe 8 are closed, and the one-way valve inside the liquid outlet pipe 6 and the sewage pipe 7 is opened. The filtered yellow slurry water is discharged from the liquid outlet pipe 6, completing the filtering and extraction of the yellow slurry water. When the piston bowl 12 descends, the limiting bead 213 slides in the inclined groove of the driving groove 212, and the limiting ring 214 drives the driving column 211 to rotate through the limiting bead 213 and the driving groove 212, and then drives the filter screen shell 215 to rotate through the gear 1 210 and the gear ring 29, so that the clean part of the filter screen shell 215 continues to rotate to the opening periphery of the liquid outlet 22, and the part of the filter screen shell 215 that has filtered the yellow slurry water rotates toward the sweeping mechanism 3. At the same time, the sludge residue on the inner periphery of the filter screen shell 215 is scraped off through the scraping groove 25 and falls to the inner lower part of the liquid outlet 22, and at the same time, the baffle 23 is closed by the spring 1 24. The sludge residue scraped off will be discharged into the interior of the sewage collecting pipe 28 through the collecting pipe 26 and the collecting port 27 due to the internal pressurization of the outer pump housing 11, and discharged through the sewage discharge pipe 7. When the piston bowl 12 rises, the limiting bead 213 slides in the straight groove of the driving groove 212, so that when the piston bowl 12 rises, the yellow slurry water can always be effectively filtered, and the filtration effect will not be deteriorated due to excessive sludge residue remaining in the filter mesh housing 215, thereby reducing the efficiency of extracting yellow slurry water. When the piston bowl 12 descends, the piston bowl 12 drives the rotating shaft 31 to descend through the sweeping roller 32, and the ratchet 34 cooperates with the ratchet 37, so that the gear 2 36 drives the ratchet 34 to rotate through the rack 38. The sweep roller 32 is driven to rotate through the rotating shaft 31, and the mesh inside of the filter mesh shell 215 is continuously swept and hooked out, and the water falls into the inside of the collecting port 27, and then is discharged through the sewage collecting pipe 28 and the sewage discharge pipe 7. When the piston bowl 12 rises, the pawl 34 and the ratchet 37 are disengaged and engaged, so that the sweep roller 32 will not reverse during the rising process, thereby preventing the sludge residue remaining on the outside of the sweep roller 32 from being thrown back into the mesh of the filter mesh shell 215 due to the centrifugal force, thereby achieving that in the process of extracting yellow slurry water, the mesh inside the filter mesh shell 215 can be continuously cleaned, thereby further improving the filtering effect of the extracted yellow slurry water, completing the self-cleaning of the filter mesh shell 215, and reducing the maintenance cost and frequency of the equipment.
