Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of xylo-oligosaccharide feed additive preparation, in particular to a self-cleaning reciprocating crushing assembly based on xylo-oligosaccharide feed additive pre-processing. BACKGROUND

[0002] Antibiotics are widely used in feed as growth promoters, but long-term use of antibiotics can cause serious consequences, such as drug resistance, drug residues, and decreased quality of livestock products. The emergence of probiotics has solved the potential hazards of antibiotics, but due to various reasons, the effect of probiotics is very unstable, so people have begun to develop safe green feed additives to replace antibiotics.

[0003] Oligosaccharide feed additives are one of the current research hotspots. Oligosaccharides have been applied to the feed industry abroad. Xylo-oligosaccharides are a class of functional oligosaccharides. Xylo-oligosaccharides have the functions of improving the digestive tract flora of livestock and poultry, promoting the growth of beneficial bacteria in the digestive tract, inhibiting the reproduction of harmful microorganisms, improving the body's resistance, improving the immune function of animals, improving the growth performance of livestock and poultry, and reducing animal serum cholesterol. Therefore, xylo-oligosaccharides are often added to feed.

[0004] In the prior art, the raw material for preparing feed-grade xylo-oligosaccharides is mainly corn cob. In some areas, agricultural and forestry wastes such as straw and branches, and agricultural processing wastes such as rice husk and sugarcane residue are used as raw materials to prepare feed-grade xylo-oligosaccharides. The main preparation methods include crushing, physical and chemical pretreatment, acid-base neutralization, enzymatic hydrolysis, desalting, decolorization, and concentration processes. In addition, a large amount of malt dextrin, corn starch, and B-cyclodextrin are added to further prepare feed additives. For the initial crushing process, the raw material of a specified particle size is required, and water is mixed. The crushed material needs to be dry-screened and filtered. The large amount of dust requires cleaning the equipment during shutdown, which affects the overall crushing and preparation rate of the raw material.

Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the application.

[0030] Referring to Figures 1-6 , the present application provides a technical solution:

[0031] Embodiment 1: For the acquisition of xylo-oligosaccharide, the lignocellulose-containing material is usually crushed and filtered, and the filtered mixed solution is subjected to high-temperature hydrothermal hydrolysis reaction, and the mixed solution after cooling is subjected to filtration treatment, so as to be subjected to subsequent treatment to obtain xylo-oligosaccharide, such as Figure 1 The crushing shell 1 can reciprocally crush the lignocellulose-containing material and can actively filter and obtain a particle size of 5-100 mesh material residue liquid. Compared with the prior art of crushing first and then transferring and dissolving and filtering, the centralized treatment equipment improves the preparation efficiency of xylo-oligosaccharide;

[0032] A feed inlet 2 is symmetrically arranged at the top of the crushing shell 1, as shown in Figure 3 The feed inlet 2 is in communication with the cylinder box two 508 of the rotary pressure filtration mechanism 5 at the end, and a plurality of annular cutters 6 are uniformly distributed on the inner wall of the cylinder box two 508, wherein the structure of the annular cutter 6 is as shown in Figure 5 The annular cutter 6 is further sleeved with a spring 7 on the outer wall of the cylinder box two 508, a fixed cover 11 is fixed on the inner wall of the top of the crushing shell 1, the fixed cover 11 is located outside the annular cutter 6, the inner wall of the fixed cover 11 is uniformly fixed with a stop block 12 through spot welding, and the stop block 12 is in abutment with the spherical body outside the annular cutter 6. Through the rotation of the cylinder box two 508 and the abutment of the spring 7, the annular cutter 6 continuously opens and closes in the cylinder box one 501 to cut the material falling in the process;

[0033] The cross section of the stop block 12 on the inner wall of the entire fixed cover 11 is similar to a triangle, and one side is in contact with the arc surface of the fixed cover 11. Due to the shape limitation of the stop block 12, the entire rotary pressure filtration mechanism 5 rotates to one side. The side lengths of the stop blocks 12 from top to bottom are different, the width of the top stop block 12 is the smallest, the width of the bottom stop block 12 is the largest, and the overall shape is inverted pyramid shape, which is convenient for the falling and cutting of the material;

[0034] An electric push rod 8 is fixedly connected to the top of the crushing shell 1, and a limiting column plate 9 slides in the entire cylinder box two 508. One end of the electric push rod 8 is connected with the limiting column plate 9. The electric push rod 8 drives the limiting column plate 9 to move up and down in the cylinder box two 508 to control the movement of the cut material. A material pipe 10 is arranged in the limiting column plate 9. Water or gas is introduced into the material pipe 10 to complete the mixing and repeated cutting of the cut material. When the air is introduced, the rising airflow carries the material to move in the cylinder box two 508 for active cutting. For the cut material, liquid is introduced for mixing, and finally discharged onto the pressure plate one 505 in the cylinder box one 501.

[0036] The annular filter plate 503 is installed on the outer surface of the barrel box 501, the annular flow cylinder 14 is fixedly sleeved on the outer periphery of the annular filter plate 503, the mixed liquid flowing out of the annular filter plate 503 is finally discharged out of the crushing shell 1 along the annular flow cylinder 14, the disc cylinder 3 is fixed on the outer periphery of the barrel box 501 and located in the crushing shell 1, the motor 4 is fixed on the top of the disc cylinder 3, the barrel box 501 sleeved with the gear sleeve 502 is driven to rotate by the motor 4, so that the whole rotating pressure filter mechanism 5 is rotated in the crushing box, the outer wall of the barrel box 501 is communicated with the disc cylinder 3, the material residues after pressure filtration are continuously accumulated, and finally are thrown into the disc cylinder 3 by the action of the centrifugal force, and finally are discharged out of the crushing shell 1 along the annular flow cylinder 13 connected with the disc cylinder 3, the collected residues are re-placed into the feeding port 2 by the previously placed material receiving disc, and are repeatedly crushed, so that the material waste is avoided;

[0038] Combining Figure 3 and Figure 6 It can be known that Figure 3 the protrusion on the lifting pipe 504 abuts against the highest point of the limiting groove 20, at this time, the pressing plate 505 in the barrel box 501 moves upward, the protrusion on the lifting rod 506 contacts the bottom of the limiting groove 21, the lifting rod 506 pulls the pressing plate 507 in the barrel box 501 to move downward, and finally the combined extrusion work of the pressing plate 505 and the pressing plate 507 is realized, like Figure 6The illustrated in the material section, and when the barrel one 501 continues to rotate, the pressure plate one 505 moves down at this time, and the whole pressure plate two 507 moves up at the same time, the electric push rod 8 pushes the limiting column plate 9 to descend, and the cut material is discharged between the pressure plate one 505 and the pressure plate two 507, and in the process of continuous extrusion, the accumulated material residues on the pressure plate one 505 increase and thicken, and at this time, the un-screened material residues need to be discharged;

[0039] At this time, the motor one 4 stops driving the barrel one 501 to rotate, and the motor two 18 on the fixed table 15 drives the limiting sleeve one 16 to rotate by 180°, at this time, the limiting groove one 20 on the limiting sleeve one 16 and the limiting groove two 21 on the limiting sleeve two 17 change the trend of rising and falling, like Figure 6 The mode two is shown, at this time, the barrel one 501 rotates, pushing the pressure plate one 505 and the pressure plate two 507 to move up at the same time, so that the material residues accumulated on the pressure plate one 505 are located on the side wall outlet side of the barrel one 501, and through the rotation of the barrel one 501, the centrifugal force generated by the rotation of the barrel one 501 can throw out the material residues, and the barrel one 501 continues to rotate, and the pressure plate one 505 and the pressure plate two 507 are extruded again to perform secondary extrusion on the residues, and finally the residues are discharged, and then the whole limiting sleeve one 16 is reset;

[0040] By controlling the rotation of the limiting sleeve one 16 on the fixed table 15, and cooperating with the rotation of the barrel one 501 on the top of the fixed table 15, the whole process of material crushing and extrusion to material distribution can be realized, and the overall rate of xylose oligomer preparation process is improved.
