Description

Technical Field

[0001] This utility model belongs to the field of continuous pressing technology for fermented liquor residue, specifically relating to a continuous pressing, dehydration, and recovery device for fermented liquor residue. Background Technology

[0002] The continuous pressing, dehydration, and recovery system for fermentation residues is a specialized piece of equipment designed for the continuous and automated pressing, dehydration, and resource recovery of fermentation residues generated in the brewing industry (such as baijiu, beer, and alcohol production). Its core function is to remove moisture from the residues through mechanical pressing, reducing subsequent processing costs (such as transportation and resource utilization), while simultaneously achieving waste liquid recovery or compliant discharge, meeting environmental protection and resource recycling requirements.

[0003] Specifically, in the actual operation of continuous pressing, dewatering, and recovery units for distillery lees fermentation residues, traditional wastewater treatment methods have revealed significant drawbacks. Most traditional units use a unified sedimentation method to treat wastewater generated during the pressing process. While this method is simple, it struggles to address the complex characteristics of distillery lees wastewater. During pressing, the wastewater often carries a large amount of foam (such as residual microorganisms from fermentation and incompletely decomposed organic matter foam) and fine particulate impurities (including broken fiber fragments and starch granules). When this mixed wastewater is uniformly transported to the sedimentation tank, it easily adheres and accumulates on the inner wall of the pipes. Over long-term operation, stubborn blockages gradually form inside the pipes, significantly reducing wastewater transport efficiency and potentially causing pipe rupture or equipment shutdown due to sudden pressure increases. Furthermore, the unified sedimentation treatment method fails to achieve effective solid-liquid separation. Foam floats on the water surface, forming a barrier layer that prevents the lower wastewater from contacting the air and inhibits the natural sedimentation process. Meanwhile, fine particles, due to their density being close to that of water, are difficult to settle quickly in static sedimentation, resulting in a significant decrease in the wastewater treatment efficiency in the sedimentation tank and making it difficult for the effluent quality to meet discharge standards. Utility Model Content

[0004] The purpose of this invention is to provide a continuous pressing, dewatering, and recovery device for fermented grain residue. This addresses the problem in existing technologies where, during pressing, the wastewater often contains a large amount of foam (such as residual microorganisms from fermentation and incompletely decomposed organic matter foam) and fine particulate impurities (including broken fiber fragments and starch granules). When this mixed wastewater is transported to the sedimentation tank, it easily adheres and accumulates on the inner wall of the pipes. Over long-term operation, stubborn blockages gradually form inside the pipes, significantly reducing wastewater transport efficiency and potentially causing pipe rupture or equipment shutdown due to sudden pressure increases.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous pressing, dehydration and recycling device for fermentation residue of distiller's grains, including a pressing and dehydration support and a pressing roller installed inside the pressing and dehydration support, wherein a liquid collection tank is connected to the inner side of the pressing and dehydration support near the pressing roller.

A stainless steel impact plate is installed on the side of the sedimentation tank near the eccentric turntable.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This invention involves continuously pressing and dewatering the fermentation residue of distiller's grains using a pressing roller. During this process, the wastewater produced falls into a collection tank. The connecting plates on both sides of the filter plate connect with the connecting seats on the side of the collection tank. Pressing the flip plate triggers a return spring, causing it to rotate along the axis. Simultaneously, the inner fitting plate of the flip plate engages with the connecting groove on the surface of the connecting plate, ensuring stable filter plate installation. The wastewater from pressing the fermentation residue is then filtered through the filter plate, allowing foam and particulate impurities to be filtered onto the filter plate surface. A pusher cylinder is then activated, driving a pusher plate to push the foam and particulate impurities onto the filter plate surface and into the collection tank. This facilitates pre-filtration during wastewater recovery, preventing blockages in the pipes and improving wastewater recovery efficiency. Attached Figure Description

[0024] A filter plate 4 is connected to the surface of the liquid collection tank 3. A pushing cylinder 5 is connected to the side of the pressing and dewatering support 1 near the filter plate 4. A slag pushing plate 6 is connected to the output end of the pushing cylinder 5. A collection tank 7 is connected to the other side of the pressing and dewatering support 1. A docking plate 8 is connected to both sides of the filter plate 4. A docking seat 9 is connected to the side of the liquid collection tank 3 near the docking plate 8. A rotating shaft 10 is connected to the outer wall of the docking seat 9. A flipping plate 11 is connected to the surface of the rotating shaft 10. A return spring 12 is connected to the inner side of the flipping plate 11. A fitting plate 13 is connected to the top of the inner wall of the flipping plate 11.

[0025] Preferably, the surface dimensions of the slag pusher plate 6 are adapted to the surface dimensions of the filter plate 4, and the filter plate 4 forms a fitting structure through the openings on the surfaces of the mating plate 8 and the mating seat 9.

[0026] In practical use, the lees residue is evenly fed into the pressing chamber by the feeding system. The rotating screw shaft pushes the residue towards the outlet. The screw pitch gradually decreases, the volumetric compression ratio increases, and the pressing force on the residue increases continuously. The water is discharged through the screen, the discharged waste liquid is collected in the collection tank 3, and the residue is discharged from the discharge port. The moisture content can be reduced to 60% to 80%.

[0027] Preferably, the rotating shaft 10 and the flip plate 11 form a rotatable connection structure, and the bottom end of the flip plate 11 and the return spring 12 form an elastic connection structure. In actual use, by rotating the flip plate 11, the return spring 12 on the inner side of the flip plate 11 is easily compressed, and the mating plate 13 is easily moved in linkage.

[0028] Preferably, the mating plate 8 has a mating groove on the side near the fitting plate 13, and the fitting plate 13 and the mating groove on one side of the mating plate 8 form a fitting structure. In actual use, by fitting the fitting plate 13 into the mating groove on one side of the mating plate 8, the filter plate 4 is quickly and stably installed.

[0029] Preferably, the bottom surface of the collection tank 3 is connected to a drain pipe 14, the bottom end of the drain pipe 14 is connected to a sedimentation tank 15, and one end of the bottom surface of the sedimentation tank 15 is connected to a discharge pipe 16. The bottom surface of the inner wall of the sedimentation tank 15 is an inclined surface structure. In actual use, the inclined sedimentation tank 15 ensures the effect of solid impurity flow and cleaning, thereby improving the quality of solid separation.

[0030] Preferably, a water pump box 17 is connected to one side of the sedimentation tank 15, a water pump pipe 18 is connected to the surface of the water pump box 17, the other end of the water pump pipe 18 is fitted into the interior of the sedimentation tank 15, and a water outlet pipe 19 is connected to the surface of the water pump box 17. In actual use, by using the water pump inside the water pump box 17, water can be easily extracted from the interior of the sedimentation tank 15 through the water pump pipe 18, thereby improving the solid-liquid separation effect.

[0031] Preferably, a servo motor 20 is connected to the outer wall of the sedimentation tank 15 via a bracket. The output end of the servo motor 20 is connected to an eccentric turntable 21. A stainless steel impact plate 22 is installed on the side of the sedimentation tank 15 near the eccentric turntable 21. In actual use, the discharge pipe 16 is connected to a suction pump, and then the servo motor 20 is started to drive the eccentric turntable 21 to rotate. At this time, the eccentric turntable 21 continuously impacts and vibrates the sedimentation tank 15, which facilitates the vibration cleaning of solid impurities on the inclined surface of the inner wall of the sedimentation tank 15.

[0032] Working principle: First, during the continuous pressing and dehydration of the fermentation residue by the press roller 2, the wastewater generated after pressing falls into the collection tank 3. During this process, the connecting plates 8 on both sides of the filter plate 4 connect with the connecting seats 9 on the side of the collection tank 3. At this time, pressing the flip plate 11 compresses the return spring 12. Due to the elastic structure of the return spring 12, the flip plate 11 rotates along the rotating shaft 10. At the same time, the fitting plate 13 on the inner side of the flip plate 11 fits into the connecting groove on the surface of the connecting plate 8, ensuring the stable installation of the filter plate 4. At this time, the wastewater after pressing the fermentation residue is filtered through the filter plate 4, so that the foam and particulate impurities are filtered onto the surface of the filter plate 4. Then, the push cylinder 5 is activated, which drives the slag pusher 6 to filter... The surface of plate 4 pushes the foam and particulate impurities into the collection tank 7, facilitating pre-filtration during wastewater recycling and preventing blockages in the pipes, thus improving wastewater recycling efficiency. Additionally, when the pre-filtered wastewater from the fermentation residue pressing enters the sedimentation tank 15 through the drain pipe 14, it undergoes sedimentation. At this point, the water pump box 17 is activated, and the sedimented water is extracted through the water pump pipe 18. Simultaneously, the servo motor 20 is activated, driving the eccentric turntable 21 to rotate. The eccentric turntable 21 continuously collides with the impact plate 22 on the outer wall of the sedimentation tank 15, ensuring the extraction and cleaning of solid impurities inside the sedimentation tank 15.
