[0002] In the field of food processing and bioenergy conversion, distiller's grains, as a by-product, are increasingly valued for their effective treatment and resource utilization. Traditionally, distiller's grains are mostly treated by simple drying or directly used as agricultural fertilizers, which is not only inefficient but also limits the exploration of their potential value. In recent years, with the advancement of technology, the refined treatment technology of distiller's grains, especially crushing and screening technology, has gradually become the key to increasing its application scope and economic value. The crushed distiller's grains can be more fully used in feed production, biomass energy preparation, and extraction of high value-added ingredients, such as functional polysaccharides, dietary fiber, etc.

[0003] Most of the wine lees crushing equipment on the current market have the following shortcomings: only one crushing box and one crushing cutter head are used, and there are no two rollers to squeeze and link each other, resulting in low crushing efficiency and imprecise crushing particle size control, which makes it difficult to meet the specific particle size requirements of different application scenarios. Therefore, we propose a wine lees crushing device and screening structure. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown, a wine lees crushing device provided by an embodiment of the utility model includes a main box body 3, a feeding port 5 is provided on the upper part of the main box body 3, a first crushing box body 13 is fixedly connected to the upper side of the interior of the main box body 3, two crushing rollers 19 are rotatably connected to the interior of the first crushing box body 13, and an annular blade is welded to the outer side of the crushing roller 19, a motor for driving the crushing roller 19 to rotate is fixedly connected to the rear side of the first crushing box body 13, a first discharge port 18 is opened on the left and right sides of the first crushing box body 13, a second crushing box body 14 is provided at the lower part of the first crushing box body 13, the upper diameter of the second crushing box body 14 is larger than the lower diameter, a driving motor 17 is fixedly connected to the lower side of the bottom of the second crushing box body 14, and the upper end of the output shaft of the driving motor 17 passes through the bottom of the second crushing box body 14 and is welded to a crushing cutter head 2.

[0022] By welding an annular blade on the outside of the crushing roller 19, efficient shearing and crushing of the wine lees is achieved. The design of the annular blade not only increases the crushing contact area and improves the crushing efficiency, but also ensures the uniformity of the particle size of the crushed material through continuous cutting action. This design is particularly effective for materials such as wine lees that contain a lot of fiber, reducing the possibility of fiber winding equipment, reducing maintenance frequency, and improving the ability of the equipment to operate continuously.

[0023] By setting the second crushing box 14 at the bottom of the first crushing box 13, a two-stage crushing structure is formed. After the double crushing rollers 19 in the first crushing box 13 complete the initial crushing, the material falls into the second crushing box 14 by gravity for further refinement. The conical design of the second crushing box 14 is not only conducive to material aggregation and promotes uniform crushing, but also enhances the contact opportunity between the material and the crushing blade 2 through top-down flow, further reducing the particle size. This cascade design improves the crushing accuracy and efficiency, and meets the diverse requirements of crushing fineness in different application fields.

[0024] Two strip baffles 12 are welded to the upper part of the main box body 3 , and the strip baffles 12 are welded to the first crushing box body 13 .

[0025] The upper part of the second pulverizing box 14 is welded to the inner wall of the main box 3 , a second discharge port is opened on the right side of the second pulverizing box 14 , and a discharge hose 7 is fixedly connected to the right side of the second pulverizing box 14 .

[0026] The welding of the upper part of the second crushing box 14 and the inner wall of the main box 3 ensures the stability of the structure, and the second discharge port opened on the right cooperates with the fixed discharge hose 7 to achieve rapid and smooth discharge of the crushed product. The conical design of the second crushing box 14 is conducive to the flow of materials from top to bottom, promoting uniform crushing. At the same time, the hose connection method simplifies the discharge process, reduces residues, facilitates cleaning and maintenance, and improves the continuity and efficiency of the overall operation.

[0027] The top of the feeding port 5 is connected with a cover plate 4 via a rotating shaft, and a magnet block is embedded inside the cover plate 4. The feeding port 5 is an iron layer body.

[0028] The cover plate 4 connected to the top of the feeding port 5 by a rotating shaft is not only convenient for operators to open and close, but the magnet block embedded inside can adsorb the feeding port 5 of the iron layer, which is suitable for industrial environments with frequent opening and closing.

[0029] A switch 1 is provided on the right side of the main box body 3, a strip plate 15 is welded to the front side of the main box body 3, and an inspection door 6 is connected to the strip plate 15 by bolts.

[0030] The design of the front welded strip plate 15 and the bolted inspection door 6 provides a convenient passage for regular inspection and maintenance of the equipment. The internal components can be inspected and repaired without complicated disassembly, which reduces the difficulty and cost of maintenance and improves the maintainability of the equipment.

[0031] In addition, the utility model also discloses a screening structure, including a wine lees crushing device, and also includes a screening shell 8, the upper part of the screening shell 8 is connected to an upper cover, the lower part of the screening shell 8 is connected to a lower cover, a plurality of screening barrels 16 are arranged inside the screening shell 8, the lower part of the screening shell 8 is connected to a bottom plate 11 through a spring rod 10, and a vibration motor 9 is fixedly connected to the right side of the screening shell 8.

[0032] The plurality of sieve barrels 16 disposed inside the screening housing 8 realizes multi-stage screening of the material. Different sieve barrels 16 can be configured with sieves of different apertures according to the required particle size requirements, so as to complete different coarse and fine classifications at one time, thereby improving the screening efficiency and flexibility, and meeting the specific requirements of different application fields for the particle size of distiller's grains, such as feed processing requires a coarse particle size, while fermentation and hydrogen production prefers fine powder.

[0033] The vibration motor 9 fixedly connected to the right side of the screening housing 8 is the key driving component of the screening structure. The introduction of the vibration motor 9 realizes the periodic vibration of the screening housing 8 and the screen barrel 16 inside it, enhances the jumping movement of the material on the screen, promotes the effective separation between particles, improves the screening efficiency and screening quality, and solves the problems of low efficiency and easy clogging of traditional static screening.

[0034] When in use, the operator puts the lees into the main box 3 through the feeding port 5, and the double crushing rollers 19 installed therein are equipped with annular blades on the outside, which rotate at high speed under the drive of the motor to perform preliminary crushing on the materials. This design not only improves the crushing efficiency, but also ensures the uniformity of crushing.

[0035] The materials after preliminary crushing automatically fall into the second crushing box 14 at the bottom. The conical design of the box helps the materials to concentrate and move further toward the crushing cutter head 2, and is driven by another drive motor 17 for deep crushing. This two-stage crushing design not only improves the crushing fineness, but also naturally screens through the conical structure to prepare for subsequent screening.

[0036] The crushed lees then enter the screening structure. Multiple screen barrels 16 inside the screening housing 8 are graded according to the particle size requirements. The vibration motor 9 drives the housing to vibrate, so that the material jumps on the screen and passes through the screen. Large particles remain above the screen and fine powder passes through the screen. The crushed lees are collected through the discharge hose 7 connected to the second discharge port on the right side for subsequent processing or transportation.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
