Description

Technical Field

[0001] The invention relates to the technical field of preparation of xylooligosaccharide feed additives, in particular to a self-cleaning reciprocating crushing component based on pre-processing of xylooligosaccharide feed additives. Background Art

[0002] Antibiotics are widely used in feed as growth promoters, but long-term use of antibiotics can easily lead to serious consequences, such as drug resistance, drug residues and deterioration of livestock product quality. The emergence of probiotics solves the potential hazards of antibiotics, but for various reasons, the effect of probiotics is very unstable, so people began to develop safe green feed additives that can replace antibiotics. Oligosaccharide feed additives are one of the hot topics in current research. Foreign countries have applied oligosaccharides to the feed industry. Xylooligosaccharides are a type of oligosaccharide substance with strong functionality. Xylooligosaccharides 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, and improving the body's resistance. At the same time, they can also improve animal immunity, improve livestock and poultry growth performance, and reduce animal serum cholesterol. Therefore, it is common to add xylooligosaccharides to feed; In the prior art, the raw material for preparing feed-grade xylooligosaccharides is mainly corn cobs. In some areas, feed-grade xylooligosaccharides are prepared from agricultural and forestry wastes such as straw and branches and agricultural processing wastes such as rice husks and sugarcane bagasse. The main preparation methods include crushing, physical and chemical pretreatment, acid-base neutralization, enzymatic hydrolysis, desalting, decolorization and concentration. The obtained xylooligosaccharides still need to be added with a large amount of auxiliary materials such as maltodextrin, corn starch and B-cyclodextrin to be further made into feed additives. For the crushing treatment at the initial stage of preparation, it is necessary to obtain raw materials with a specified particle size, add water and mix. Usually, the materials crushed by the crusher need to be dry screened and filtered. The dust is large and the equipment needs to be shut down for cleaning, which affects the crushing and preparation rate of the entire raw material. To this end, we proposed a self-cleaning reciprocating crushing component based on the pre-processing of xylo-oligosaccharide feed additive. Summary of the invention

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See also Figure 1-6 , the present invention provides a technical solution: Example 1: To obtain xylooligosaccharides, the material containing lignocellulose is usually crushed and filtered, the filtered mixed liquid is subjected to high-temperature hydrothermal hydrolysis, the cooled mixed liquid is filtered, and then the subsequent treatment is performed to obtain xylooligosaccharides, such as Figure 1 The crushing shell 1 shown can reciprocately crush the material containing lignocellulose, and can actively filter to obtain the residual liquid of the material with a particle size of 5-100 meshes. Compared with crushing first and then transferring, dissolving and filtering, the centralized processing equipment improves the efficiency of preparing xylooligosaccharides; A feed inlet 2 is symmetrically arranged at the top of the crushing shell 1. Figure 3 As shown, the end of the feed port 2 is connected to the barrel box 508 of the rotating filter press mechanism 5, and a plurality of annular cutters 6 are evenly distributed on the inner wall of the barrel box 508, wherein the structure of the annular cutter 6 is as shown in FIG. Figure 5 As shown, the annular cutter 6 is located on the outer wall of the barrel box 508 and is also sleeved with a spring 7. A fixed cover 11 is fixed on the inner wall of the top of the crushing shell 1. The fixed cover 11 is located on the outer side of the annular cutter 6. The inner wall of the fixed cover 11 is evenly fixed with a stopper 12 by spot welding, and the stopper 12 abuts against the outer sphere of the annular cutter 6. Through the rotation of the barrel box 508 and the abutment of the spring 7, the annular cutter 6 continuously opens and closes in the barrel box 501 to cut the material in the falling process. The section of the stopper 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 of the stopper 12, the entire rotary filter press mechanism 5 rotates toward one side. At the same time, the side lengths of the stoppers 12 from top to bottom are different. The width of the top stopper 12 is the smallest, and the width of the bottom stopper 12 is the largest. The overall distribution is in the shape of an inverted pyramid, which is convenient for the falling and cutting of materials. An electric push rod 8 is fixedly connected to the top of the crushing shell 1, and a limiting column plate 9 is slidably arranged in the entire barrel box 508. One end of the electric push rod 8 is connected to the limiting column plate 9, and the limiting column plate 9 is driven by the electric push rod 8 to move up and down in the barrel box 508 to control the movement of the cut materials. At the same time, a feeding pipe 10 is arranged in the limiting column plate 9. By introducing water or gas into the feeding pipe 10, the mixing and repeated cutting of the cut materials are completed. During ventilation, the rising air flow is used to drive the materials to move in the barrel box 508 for active cutting. The cut materials are mixed with liquid and finally discharged onto the pressing plate 505 in the barrel box 501.

[0017] Embodiment 2: For obtaining fine broken materials, barrel box 1 501 and barrel box 2 508 are connected through channel 509, and barrel box 2 508 located on one side of channel 509 is provided with slidingly mounted pressing plate 1 505 and pressing plate 2 507, and a lifting pipe 504 is also installed at the bottom of barrel box 1 501, one side of the lifting pipe 504 passes through barrel box 1 501 and is fixed to pressing plate 1 505, and a lifting rod 506 is slidably connected in the lifting pipe 504, and one end of the lifting rod 506 is fixed to pressing plate 2 507, so that the movement of pressing plate 1 505 and pressing plate 2 507 is controlled by the movement of lifting pipe 504 and lifting rod 506, so as to perform the pressing and filtering operation on the materials; An annular filter plate 503 is installed on the outer surface of the barrel box 501, and an 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 from the crushing shell 1 along the annular flow cylinder 14. A disc 3 is fixed on the outer periphery of the barrel box 501 and located inside the crushing shell 1. A motor 4 is fixed on the top of the disc 3. The barrel box 501 sleeved with a gear sleeve 502 is driven to rotate by the rotation of the motor 4, so that the entire rotating filter press mechanism 5 is rotated in the crushing box, and the outer wall of the barrel box 501 is connected to the disc 3. The material residue after the filter press is continuously accumulated and finally thrown into the disc 3 by the action of centrifugal force, and finally discharged from the crushing shell 1 along the annular flow cylinder 13 connected to the disc 3, and the collected residue is put back into the feed port 2 through the pre-placed receiving tray, and reciprocating crushing is performed to avoid material waste; For the rotation of the barrel box 501, a fixed limiting sleeve 17 is sleeved on the fixed platform 15 located at the bottom support, and a limiting sleeve 16 is movably connected to the fixed platform 15 on the top of the limiting sleeve 17. At the same time, a motor 18 is fixed to the side wall of the fixed platform 15 by bolts. The gear on the output end of the motor 18 is meshed and connected with the gear sleeve 19 on the limiting sleeve 16. The limiting sleeve 16 is driven to rotate by the operation of the motor 18, thereby adjusting the section track of the limiting groove 20 on the outer wall of the limiting sleeve 16 and the upper limit groove 21 of the limiting sleeve 17; Combination Figure 3 and Figure 6 It can be seen that Figure 3 The protrusion on the middle lifting tube 504 abuts against the limiting groove 20 and is the highest point on the limiting groove 20. At this time, the pressing plate 505 located in the barrel box 501 moves upward, and the protrusion on the lifting rod 506 contacts the bottom of the limiting groove 21, causing the lifting rod 506 to pull the pressing plate 2 507 located in the barrel box 501 to move downward, and finally realize the joint extrusion work of the pressing plate 1 505 and the pressing plate 2 507. Figure 6 In the material pressing section shown in the figure, when the barrel box 1 501 continues to rotate, the pressing plate 1 505 moves downward, and the entire pressing plate 2 507 moves upward. 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 pressing plate 1 505 and the pressing plate 2 507. During the continuous extrusion and feeding process, the material residues accumulated on the pressing plate 1 505 increase and thicken. At this time, it is necessary to discharge these unscreened material residues; At this time, the motor 14 stops driving the barrel box 1501 to rotate. In contrast, the motor 218 on the fixed platform 15 drives the limit sleeve 16 to rotate 180 degrees. At this time, the upper limit slot 120 of the limit sleeve 16 and the upper limit slot 21 of the limit sleeve 217 change their fluctuation trend, such as Figure 6As shown in the second mode, after the barrel box 1 501 rotates, the pressing plate 1 505 and the pressing plate 2 507 are pushed upward at the same time, so that the material residue accumulated on the pressing plate 1 505 is located at the outlet side of the side wall of the barrel box 1 501. After the barrel box 1 501 rotates, the centrifugal force generated throws the material residue out. The barrel box 1 501 continues to rotate, and the pressing plate 1 505 and the pressing plate 2 507 squeeze again, and the residue is squeezed for the second time, and finally the residue is discharged, and then the entire limit sleeve 16 is controlled to reset; By controlling the limiting sleeve 16 to rotate on the fixed platform 15, and then coordinating the barrel box 501 to rotate on the top of the fixed platform 15, the whole process from material crushing and extrusion to material distribution is realized, thereby improving the overall rate of the oligoxylose preparation process.

[0018] The working process and principle of the present invention are as follows: Put the biomass raw material containing lignocellulose into the feed port 2, start the motor 1 4 on the drum 3, and the motor 1 4 drives the entire drum box 1 501 and the drum box 2 508. After the annular cutter 6 on the side wall of the drum box 2 508 contacts the stopper 12 on the inner wall of the fixed cover 11, it starts to cyclically cut the biomass raw material entering from the feed port 2, and then continuously passes water and air into the drum box 2 508 through the feed pipe 10, so as to achieve cutting and mixing at the same time; After the cutting and mixing time is reached, the electric push rod 8 pushes the limiting column plate 9 to descend, and the mixed liquid comes to the space between the first pressing plate 505 and the second pressing plate 507 along the channel 509. The lifting tube 504 moves in the limiting groove 10 on the limiting sleeve 16 and cooperates with the lifting rod 506 in the limiting groove 21 on the limiting sleeve 2 17 to realize the pressing of the first pressing plate 505 and the second pressing plate 507, and squeeze the residual liquid in the mixture and press it into the second annular flow tube 14 from one side of the annular filter plate 503; For the residue left on the pressing plate 505, the motor 18 controls the limiting sleeve 17 to turn 180 degrees, so that the pressing plate 505 and the pressing plate 507 rotate and lift the residue at the same time, and the centrifugal force generated by the rotation throws the residue from the outer wall of the barrel into the annular flow cylinder 13, and finally discharged from the crushing shell 1, and after being collected, it is put back into the feed port 2 for cyclic crushing treatment.
