Description

Technical Field

[0001] This utility model relates to the field of yeast wastewater treatment technology, and in particular to an integrated yeast wastewater treatment machine based on the synergistic effect of ozone oxidation and fiber filtration. Background Technology

[0002] Yeast (such as brewer's yeast and baker's yeast) is a single-celled fungus widely used in food, brewing, and medicine. Its industrial production process mainly revolves around "strain cultivation → large-scale propagation → isolation and purification," with the core being the provision of suitable nutrients (carbon source, nitrogen source, etc.) and environment (temperature, pH, oxygen) to promote the large-scale proliferation of yeast cells.

[0003] Yeast production generates high-concentration, recalcitrant, and dark-colored organic wastewater (such as fermentation residue and rinsing water). This wastewater requires decontamination before discharge. Ozone oxidation and fiber filtration can be used in tandem to treat this wastewater. First, ozone is introduced into the wastewater, breaking down unsaturated bonds (such as aromatic compounds and conjugated double bonds) and degrading large organic molecules (such as yeast metabolites, pigments, and proteins), significantly reducing the wastewater's chemical oxygen demand (COD) and color. The pre-treated wastewater is then pumped into another chamber equipped with a fiber-based filter membrane to remove suspended solids, colloidal particles, and some residual organic matter, further reducing turbidity and COD. However, in traditional equipment, the ozone injection pipe has limited height and is typically fixed at the bottom of the equipment, preventing proper mixing of ozone with the wastewater and affecting the purification effect. Summary of the Invention

[0004] Therefore, it is necessary to provide an integrated yeast wastewater treatment machine based on the synergy of ozone oxidation and fiber filtration, which can effectively improve the mixing uniformity of ozone and wastewater, in order to address the above-mentioned technical problems.

[0005] The integrated yeast wastewater treatment machine based on the synergy of ozone oxidation and fiber filtration provided by this utility model includes a reaction vessel and a feed inlet opened on the top of the reaction vessel. The feed plate is movably hinged and installed inside the feed inlet; Multiple through holes are provided at the bottom of the reactor. A sealing ring is fixedly installed inside the through hole; The aeration pipe is movably disposed inside the sealing ring, and its exterior is tightly fitted to the inner wall of the sealing ring. Multiple air holes are formed on the upper surface of the aeration pipe. The lifting assembly is located at the bottom of the reactor and drives the aeration pipe to move up and down reciprocally.

[0006] In one embodiment, the lifting assembly includes a rotating cylinder, which is rotatably mounted at the bottom of the reactor, below the through hole. The inner wall of the rotating cylinder is provided with a curved groove, and a limit rod is fixedly provided on the side wall of the aeration pipe. The end of the limit rod away from the aeration pipe is slidably engaged with the curved groove.

[0007] In one embodiment, the plurality of rotating cylinders are connected by a first belt drive.

[0008] In one embodiment, a movable cylinder is movably disposed through the middle of the reactor, the bottom of the movable cylinder movably penetrates the inner wall of the bottom of the reactor, and multiple movable rods are movably disposed outside the movable cylinder, with multiple stirring rods fixedly installed in a linear array outside the movable rods.

[0009] In one embodiment, the bottom of the movable cylinder is connected to the outer wall of one of the rotating cylinders via a second belt drive.

[0010] In one embodiment, a fixed rod is movably disposed through the center of the movable cylinder, a first bevel gear is fixedly sleeved on the outside of the fixed rod, a second bevel gear is fixedly disposed at the end of the movable rod located inside the movable cylinder, the second bevel gear meshes with the first bevel gear for transmission, a positioning plate is fixedly sleeved on the top outside of the fixed rod, and the positioning plate is fixedly connected to the inner wall of the reactor.

[0011] In one embodiment, the number of movable rods is set to multiple, arranged in a linear array from top to bottom along the movable cylinder, and the number of the first bevel gears is the same as the number of layers of the movable rods.

[0012] The aforementioned integrated yeast wastewater treatment machine based on the synergy of ozone oxidation and fiber filtration can change the height of the aeration pipe and air holes in the reactor through the lifting component, so that ozone can be mixed with wastewater at different depths, thereby improving the wastewater purification quality.

[0021] The following is combined with Figures 1-6 This invention describes an integrated yeast wastewater treatment machine based on the synergistic effect of ozone oxidation and fiber filtration.

[0022] like Figures 1-5 As shown, in one embodiment, the integrated yeast wastewater treatment machine based on the synergy of ozone oxidation and fiber filtration includes a reaction vessel 1, a feed plate 2, a sealing ring 3, an aeration pipe 4, and a lifting assembly 5.

[0023] The reactor 1 has a feed inlet 101 at the top, and a feed plate 2 is hinged inside the feed inlet 101. A sealing ring 3 is installed in a through hole 102 at the bottom of the reactor 1 to prevent wastewater from overflowing. An aeration pipe 4 is movably installed inside the sealing ring 3 and has multiple air holes 41 at the top. The lifting assembly 5 can move the aeration pipe 4 up and down relative to the sealing ring 3 to adjust the position of the air holes 41 inside the reactor 1.

[0024] Specifically, the feed plate 2 is opened, and wastewater generated during yeast production is added to the reactor 1 through the feed port 101. After the addition is complete, the feed plate 2 is closed. The bottom of the aeration pipe 4 is connected to an air pipe, one end of which is connected to the ozone generating device. The air pipe is a flexible pipe. When the ozone generating device is turned on, ozone gas enters the aeration pipe 4 through the air pipe and is discharged through the air hole 41. The discharge through multiple air holes 41 can increase the contact area between ozone and wastewater. The sealing ring 3 can ensure that wastewater does not overflow through the through hole 102. The lifting component 5 can drive the aeration pipe 4 to move up and down along the sealing ring 3. The height of the air hole 41 in the reactor 1 will also change. This allows ozone to mix with wastewater at different depths, improving the uniformity of ozone-wastewater mixing.

[0025] See Figures 2-5 As shown, in this embodiment, the lifting assembly 5 includes a rotating cylinder 51, which is rotatably installed at the bottom of the reactor 1, below the through hole 102. A curved groove 52 is provided on the inner wall of the rotating cylinder 51, and a limiting rod 53 is fixedly provided on the side wall of the aeration pipe 4. The end of the limiting rod 53 away from the aeration pipe 4 slides and fits against the curved groove 52.

[0026] Specifically, after ozone is discharged into the wastewater through the vent 41, the rotating drum 51 is rotated. The rotation of the rotating drum 51 will drive the curved groove 52 to rotate. Since the curved groove 52 is in sliding contact with the limiting rod 53, the rotating drum 51 will drive the limiting rod 53 and the aeration pipe 4 to move up and down once after rotating one revolution and then return to the initial position. The height of the vent 41 changes, and the ozone and wastewater are mixed more evenly.

[0027] See Figure 1 and Figure 3 As shown, in this embodiment, multiple rotating cylinders 51 are connected by a first belt 6.

[0028] Specifically, the rotation of one rotating drum 51 can be driven by the first belt 6 to enable multiple rotating drums 51 to rotate synchronously together, and multiple aeration pipes 4 can move up and down back and forth, which can further improve the mixing uniformity of ozone and wastewater.

[0029] See Figure 2 and Figure 6 As shown, in this embodiment, a movable cylinder 7 is movably connected through the middle of the reactor 1, and the bottom of the movable cylinder 7 movably connects through the bottom inner wall of the reactor 1. Multiple movable rods 8 are movably connected outside the movable cylinder 7, and multiple stirring rods 9 are fixedly installed in a linear array outside the movable rods 8.

[0030] Specifically, while ozone is being introduced, the motor of the movable cylinder 7 is started. The rotation of the movable cylinder 7 will drive multiple movable rods 8 to revolve together, and the stirring rod 9 will also rotate together. During the rotation of the stirring rod 9, the wastewater will be agitated. The stirring rod 9 will break the static state of the water and form local turbulence. On the one hand, the turbulence will shear the ozone bubbles, breaking larger bubbles into smaller bubbles and increasing the gas-liquid contact area. On the other hand, the stirring can make the wastewater in the reactor 1 circulate, preventing ozone bubbles from concentrating in local areas, allowing undissolved ozone to come into contact with more wastewater, and reducing the "short circuit" phenomenon (bubbles escape before fully reacting).

[0031] See Figure 3 As shown, in this embodiment, the bottom of the movable cylinder 7 is connected to the outer wall of one of the rotating cylinders 51 by a second belt 10.

[0032] Specifically, through the transmission action of the second belt 10, while the movable cylinder 7 rotates and drives the movable rod 8 and the stirring rod 9 to stir the wastewater, it also drives one of the rotating cylinders 51 to rotate. Through the action of the first belt 6, the other rotating cylinders 51 also rotate synchronously, which can simultaneously realize the stirring rod 9 to stir the wastewater and change the ozone filling height.

[0033] See Figure 2 and Figure 6 As shown, in this embodiment, a fixed rod 11 is movably and through the center of the movable cylinder 7. A first bevel gear 12 is fixedly sleeved on the outside of the fixed rod 11. A second bevel gear 13 is fixedly sleeved at the end of the movable rod 8 located inside the movable cylinder 7. The second bevel gear 13 meshes with the first bevel gear 12 for transmission. A positioning plate 14 is fixedly sleeved on the top outside of the fixed rod 11. The positioning plate 14 is fixedly connected to the inner wall of the reactor 1.

[0034] Specifically, the rotation of the movable cylinder 7 will drive the movable rod 8 and the stirring rod 9 to revolve synchronously. The movable rod 8 and the second bevel gear 13 rotate around the fixed rod 11 and the first bevel gear 12, while the fixed rod 11 and the first bevel gear 12 remain stationary. The positioning plate 14 provides support for the fixed rod 11. During the rotation of the second bevel gear 13, it will mesh with the first bevel gear 12 and thus rotate on its own axis. The rotation of the second bevel gear 13 will drive the movable rod 8 to rotate relative to the movable cylinder 7, thereby causing the stirring rod 9 to rotate on its own axis while revolving with the movable cylinder 7. This can further improve the stirring effect on the wastewater and make the ozone and wastewater mix more evenly.

[0035] See Figure 6 As shown, in this embodiment, multiple movable rods 8 are arranged in a linear array from top to bottom along the movable cylinder 7, and the number of first bevel gears 12 is the same as the number of layers of movable rods 8.

[0036] Specifically, multiple movable rods 8 are arranged in a circular array at the same height outside the movable cylinder 7. Multiple movable rods 8 and stirring rods 9 are arranged at multiple heights from top to bottom. The number of first bevel gears 12 is the same as the number of layers. That is, during the rotation of the movable cylinder 7, multiple layers of movable rods 8 and stirring rods 9 will rotate on their own, which can promote the uniformity of mixing wastewater and ozone.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
