Description

Technical Field

[0001] This invention relates to the field of distillers' grains recycling and reuse technology, specifically to solid-liquid separation equipment for distillers' grains recycling and reuse. Background Technology

[0002] Distillers' grains (or lees) are the residue left after brewing alcohol from grains such as rice, wheat, and sorghum. Rich in crude protein, trace elements, and vitamins, they can be used as animal feed or processing raw materials. As a byproduct of brewing, fermentation with lactic acid bacteria improves palatability and nutritional utilization, making them suitable for cattle feed. Adding sodium bicarbonate helps regulate acidity and prevent rumen bloat. Modern technology converts them into biogas power generation, organic fertilizer, and biomass fuel. One method of biomass energy production is converting baijiu (Chinese liquor) lees into biomass fuel rods through drying and molding. Compared to coal, diesel, and natural gas, burning lees offers advantages such as higher calorific value (close to bituminous coal), higher boiler thermal efficiency, minimal environmental pollution from exhaust emissions, and lowest combustion costs, making it an ideal alternative to coal.

[0003] Currently, in the recycling and reuse of distiller's grains, solid-liquid separation is required. Existing technologies generally employ extrusion or pressing methods. However, distiller's grains often exhibit a large number of clumps before being poured in, and even after crushing, a certain amount of clumps remain, containing a significant amount of water. Consequently, the solid-liquid separation during extrusion is not thorough enough, requiring multiple processing steps or directly resulting in a high water content in the recycled distiller's grains, which causes inconvenience for subsequent processing and storage. Therefore, this invention proposes a solid-liquid separation device for the recycling and reuse of distiller's grains. Summary of the Invention

[0022] Please see Figures 1-6In this embodiment, a solid-liquid separation device for recycling and reusing distiller's grains is provided, including a pretreatment tank 1. A distiller's grains inlet 11 is provided on the rear side wall of the pretreatment tank 1. A swing drive mechanism 3 is installed at the top of the interior of the pretreatment tank 1, and a swing component 4 is installed on the swing drive mechanism 3. A sweeping component 41 is provided at the bottom of the swing component 4. A linkage rod 44 is movably connected to one side of the sweeping component 41 through a steering connector 43. A sliding sleeve 5 is rotatably hinged to the end of the linkage rod 44 away from the steering connector 43. A telescopic component 51 is rotatably installed on the sliding sleeve 5. A roller 52 is rotatably installed at the bottom of the telescopic component 51. A filter screen 12 is installed on the bottom wall of the pretreatment tank 1 at the lower surface of the roller 52. A horizontally arranged guide is fixedly installed on one side of the pretreatment tank 1. The guide rod 53 and the sliding sleeve 5 are slidably installed on the guide rod 53. The lower surface of the pretreatment box 1 is provided with a separation box 2. The separation box 2 is provided with a recovery liquid pipe 24 and a dry lees material collection door 26. After the lees enter the pretreatment box 1 from the lees inlet 11, the swing drive mechanism 3 drives the swing component 4 and the sweeping component 41 to swing and flatten the lees. At the same time, the sliding sleeve 5 and the roller 52 are driven to reciprocate along the guide rod 53 through the steering connector 43 and the linkage rod 44. The telescopic component 51 provides elastic pressure to make the roller 52 roll tightly against the filter screen 12, realizing the crushing of the clumped lees and the initial solid-liquid separation. The pretreated lees fall into the separation box 2 for deep solid-liquid separation. The liquid is recovered through the recovery liquid pipe 24 and the dry material is taken out through the dry lees material collection door 26.

[0023] In this embodiment, the swing drive mechanism 3 includes a drive rod 31 rotatably mounted on the pretreatment box 1, and the drive rod 31 is driven to rotate by a drive motor 33. A Z-shaped component 32 is provided on the drive rod 31, and a movable sleeve 45 is movably sleeved on the Z-shaped component 32. The bottom of the movable sleeve 45 is fixedly connected to the swing component 4. The drive motor 33 drives the drive rod 31 to rotate, causing the Z-shaped component 32 to rotate synchronously. The Z-shaped component 32 drives the movable sleeve 45 and the swing component 4 fixed thereto to generate [something] through its unique shape. The oscillation along a specific trajectory effectively drives the sweeping component 41 to work; the Z-shaped component 32 includes a first end rod 34, a second end rod 35, and a middle rod 36. The first end rod 34 and the second end rod 35 are respectively fixedly connected to the two ends of the middle rod 36. The drive rod 31 is horizontally arranged, and the first end rod 34 and the second end rod 35 are both inclinedly arranged on the drive rod 31. The movable sleeve 45 is movably sleeved on the outer surface of the middle rod 36. When the drive rod 31 rotates, the inclined arrangement of the first end rod 34 and the second end rod 35... This causes a change in the movement trajectory of the central rod 36, which in turn drives the movable sleeve 45 and the rotating swing component 4 to produce a compound swing, enhancing the uniformity and coverage of the sweeping. The steering connector 43 includes a first U-shaped component 431, a cross component 432, and a second U-shaped component 433. The first U-shaped component 431 is fixedly connected to the linkage rod 44, and the cross component 432 is movably connected between the first U-shaped component 431 and the second U-shaped component 433. An extension rod 4 is fixedly connected to the end of the second U-shaped component 433 away from the cross component 432. 34, and the extension rod 434 is rotatably connected to the top inner surface of the sweeping component 41. When the drive motor 33 drives the drive rod 31 to rotate, it can drive the Z-shaped component 32 to rotate synchronously. The rotating Z-shaped component 32 can cause the central rod 36 to change direction, thereby causing the movable sleeve 45, the rotating swing component 4, and the sweeping component 41 to swing. This swing is also accompanied by a small-amplitude circular motion, that is, the whole body makes a narrow elliptical trajectory motion, so as to effectively sweep the lees on the surface of the filter screen 12.

[0024] In this embodiment, the bottom of the sweeping component 41 is provided with brush bristles 42. The sweeping component 41 can be used to sweep the lees during the swinging process and prevent the lees from clogging the filter screen 12. In addition, the sweeping of the sweeping component 41 can spread the lees well on the surface of the filter screen 12, which can help the roller 52 to crush the lees and thus improve the pretreatment of the clumped lees.

[0025] In this embodiment, the telescopic component 51 includes a telescopic inner rod 54, an inner rod sleeve 55, and a spring 56. The telescopic inner rod 54 is slidably disposed inside the inner rod sleeve 55. One end of the spring 56 is connected to the telescopic inner rod 54. The spring 56 is used to provide elastic pressure to the telescopic inner rod 54, so that the roller 52 is tightly attached to the filter screen 12. When the roller 52 rolls repeatedly, it can increase the working length of the roller 52 and can be retracted in time to ensure the continuity and stability of the crushing effect.

[0026] In this embodiment, the separation chamber 2 is provided with a separation chamber 21, and a separation filter cartridge 23 is installed in the separation chamber 21. The separation filter cartridge 23 is driven to rotate by the separation motor 22. The pretreated lees enter the separation chamber 21 and the separation filter cartridge 23 is driven to rotate by the separation motor 22, and deep solid-liquid separation is carried out under the action of centrifugal force and extrusion.

[0027] In this embodiment, a rotary sealing seat 25 is rotatably installed at the bottom of the separating filter cartridge 23. The rotary sealing seat 25 can ensure that the separating filter cartridge 23 is driven to rotate, thereby separating the solid and liquid of the lees. At the same time, it can prevent the separated lees liquid from flowing back to the output shaft of the separating motor 22 and causing adverse effects on the separating motor 22, thus improving the reliability and service life of the equipment.

[0028] In this embodiment, the recovery liquid pipe 24 is located at the bottom of the separation tank 2 and is used to discharge the lees liquid in the separation chamber 21. There are multiple recovery liquid pipes 24. By setting multiple recovery liquid pipes 24, the liquid discharge speed can be accelerated, the liquid accumulation in the separation chamber can be prevented, and the solid-liquid separation efficiency can be ensured.

[0029] In this embodiment, the dry lees receiving door 26 is hinged to one side of the separation box 2 for taking out the dried lees. This setting makes it convenient for operators to take out the dry lees that have completed solid-liquid separation periodically or continuously. The structure is simple and easy to use.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
