Description

Technical Field

[0001] The present application relates to the technical field of feed additive production, and in particular to a feed additive for promoting intestinal health of livestock and poultry and a preparation method thereof. Background Art

[0002] At present, more and more unfavorable factors are constantly threatening the health of livestock and poultry, leading to the occurrence of diseases. Once livestock and poultry are sick, the production efficiency of breeders will be reduced. Therefore, ensuring the health of livestock and poultry is a prerequisite for ensuring efficient production. The intestine is an important part of the animal body. Intestinal health determines the overall function and productivity level of livestock and poultry. Improving intestinal structure and function is of great significance to the development of healthy breeding. A stable intestinal environment, a complete intestinal structure and a relatively balanced intestinal microecological system are the basis of animal intestinal health. The intestine separates various substances in the intestine from the internal environment of the animal body through its special structure. While effectively digesting and absorbing nutrients, it can also prevent the invasion of harmful substances in the intestinal cavity; various complex regulatory mechanisms and signal pathways are used between the barriers of the intestinal mucosa to form a defense barrier to jointly fight against the invasion of harmful substances such as bacteria and viruses on the body. Through the mucosal barrier, the intestine can effectively prevent harmful substances such as bacteria and endotoxins in the intestinal cavity from entering the tissues or blood circulation of poultry, protecting the healthy growth of livestock and poultry. However, under adverse external conditions (such as heat stress, harmful gas stimulation, nutrient deficiency, etc.), intestinal microorganisms, endotoxins, etc. break through the intestinal barrier, leading to intestinal mucosal lesions, reduced digestive enzyme activity, and microbial flora disorders, which seriously endanger the health and production performance of livestock and poultry.

[0003] In the related art, a Chinese patent with a publication number of CN108077600A proposes a feed additive and preparation method for promoting intestinal health of livestock and poultry, and adopts cetylpyridinium chloride to modify montmorillonite to load carvacrol. The montmorillonite modified by cetylpyridinium chloride increases the interlayer spacing, specific surface area and hydrophobicity of montmorillonite, and greatly enhances the adsorption rate of carvacrol. Montmorillonite has good biocompatibility and gastrointestinal mucosal affinity, has a controlled release effect on the loaded carvacrol, can more effectively exert the antibacterial, anti-inflammatory, antioxidant and other effects of carvacrol, and has a combined synergistic and synergistic effect on antibacterial activity. The feed additive of the present invention has the characteristics of strong antibacterial effect and bacteria not easy to produce drug resistance, can effectively inhibit the proliferation of harmful bacteria in the intestinal tract of livestock and poultry, improve the height of intestinal villi and intestinal barrier function, benefit the secretion of digestive enzymes and the digestion of feed nutrients, promote the intestinal health of livestock and poultry, and can improve the production performance of livestock and poultry.

[0004] With respect to the above-mentioned related technologies, the inventors believe that there are the following defects: in the process of producing feed additives for promoting intestinal health of livestock and poultry, the final filter cake needs to be dried. If it contains moisture, it will cause problems with the powder obtained in the subsequent crushing process, such as agglomeration. However, since the filter cake is a layered solid, when it is dried, its outer surface is dried while its inner part is not. Summary of the invention

DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-5 This application is described in further detail. Embodiment 1

[0020] The present application discloses a method for preparing a feed additive for promoting intestinal health of livestock and poultry. Figure 1-Figure 5 A method for preparing a feed additive for promoting intestinal health of livestock and poultry comprises the following steps: S1. Add water to montmorillonite and sodium chloride and stir evenly to prepare a suspension slurry with a concentration of 10% to 20%, sodiumize at room temperature, and re-form the slurry with a concentration of 15% to 40% with water; S2, slowly adding cetylpyridinium chloride to the ore slurry in step S1 under stirring, and continuously stirring at room temperature for a certain period of time; S3, slowly adding carvacrol to the slurry of step S2 under stirring, and continuously stirring at room temperature for a certain period of time; S4, the reaction liquid of step S3 is dehydrated, and the obtained filter cake is dried; after drying, the inside of the filter cake needs to be inspected to see whether it is completely dried; Reference Figure 1-Figure 3, S5, crushing, to obtain a feed additive for promoting intestinal health of livestock and poultry; in S4, the inside of the filter cake is sampled and tested by a detection device, the detection device includes a sampling inspection mechanism, a testing mechanism for testing whether there is water, and a cleaning mechanism for cleaning the sampling inspection mechanism; the sampling inspection mechanism includes a frame 1, a bracket 2 lifted and arranged on the frame 1, a sampling inspection cylinder 3 rotatably arranged on the bracket 2, and a rotating component for controlling the rotation of the sampling inspection cylinder 3, the bottom end of the sampling inspection cylinder 3 is open, and the other end is closed, the length of the sampling inspection cylinder 3 is greater than the thickness of the filter cake, after the length of the sampling inspection cylinder 3 is greater than the filter cake, the sampling inspection cylinder 3 can take samples from all positions of the center of the filter cake, and thus can not only perform dryness inspection on the surface of the filter cake, but also conduct internal inspection on the filter cake. Drying detection is carried out. In the initial state, the sampling tube 3 opens downward and is directly opposite to the center of the filter cake. The lifting and lowering of the bracket 2 is achieved by an electric push rod or a cylinder. The rotating assembly is controlled by a rotating motor 4. The sampling tube 3 and the bracket 2 are rotatably connected with a rotating shaft. The output end of the rotating motor 4 is connected to the end of the rotating shaft, and the rotating shaft is located at the end of the sampling tube 3 close to the bottom closure. First, the sampling tube 3 is rotated to a position where the opening faces downward, and the bracket 2 moves downward. When the sampling tube 3 moves toward the filter cake, the sample enters the sampling tube 3. When the sampling tube 3 moves to the bottom end of the filter cake, the bracket 2 and the sampling tube 3 are moved upward until they are separated from the filter cake. The rotating motor 4 is then used to control the rotation of the sampling tube 3, and the open end of the sampling tube 3 is rotated to the top to complete the sampling work.

[0021] The testing mechanism includes an extrusion cylinder 5, an extrusion frame 6 rotatably arranged on the bracket 2, an extrusion rod 7 lifted and lowered on the extrusion frame 6, an extrusion disk 8 fixed at the bottom end of the extrusion rod 7, and an identification component arranged in the extrusion cylinder 5. One end of the extrusion cylinder 5 is open and connected to the open end of the sampling cylinder 3. A filter screen 9 is fixedly connected to the opening of the extrusion cylinder 5. The filter screen 9 is used to block the sample from entering the extrusion cylinder 5 and ensure that water can enter the extrusion cylinder 5. Similarly, an outlet is provided at the bottom end of the extrusion cylinder 5, and a solenoid valve is provided at the outlet. When the detection is completed, the water in the extrusion cylinder 5 needs to be released. The extrusion frame 6 is located above the sampling cylinder 3. The rotation of the extrusion frame 6 is realized by the extrusion motor, and the lifting and lowering of the extrusion rod 7 can be realized by an electric push rod or a cylinder. The extrusion disk 8 is adapted to the shape of the sampling cylinder 3, and can enter the extrusion cylinder 5 and squeeze water out of the sample in the extrusion cylinder 5. The identification component is used to detect whether there is water in the sample.

[0022] Reference Figure 1-Figure 3The identification component includes a test paper 10, a winding portion for winding the test paper 10, a color sensor 14, and a buzzer 15 electrically connected to the color sensor 14. The test paper 10 is movably arranged in the extrusion cylinder 5. The color sensor 14 is directly opposite to the test paper 10 and close to the bottom wall of the extrusion cylinder 5. The area of ​​the test paper 10 is larger than the area of ​​the filter screen 9 so that the squeezed water can fall onto the test paper 10. The winding portion includes two winding motors 12, a plurality of winding ropes 11, and two winding rollers 13. The winding rollers 13 are respectively located on both sides of the extrusion cylinder 5. The winding motor 12 is used to control the rotation of the winding rollers 13. In this embodiment, the test paper 10 uses cobalt chloride test paper. The cobalt chloride test paper turns red when it comes into contact with water, and then it can be judged whether there is water in the sample. The plurality of winding ropes 11 and multiple test papers 10 are arranged at intervals. When the extrusion cylinder 5 starts to release water, the winding rope 11 is located in the extrusion cylinder 5. When detection is required, the test paper 10 is located in the extrusion cylinder 5. The color sensor 14 and the buzzer 15 are controlled and connected through a PLC controller; when sampling is completed, the sampling cylinder 3 is rotated to the opening facing upward, that is, facing the extrusion disk 8, and the test paper 10 is pulled to the bottom of the filter screen 9. The sample in the sampling cylinder 3 is squeezed out of water by controlling the extrusion rod 7 and the extrusion disk 8. If the sample is not dried, water is squeezed into the extrusion cylinder 5 at this time, and the test paper 10 changes color after encountering water. The color sensor 14 recognizes that the test paper 10 changes color, and the color sensor 14 triggers the buzzer 15 to make a sound, proving that the filter cake is not dried.

[0023] The testing mechanism also includes a testing rod 16 slidably arranged on the frame 1, an absorbent paper 17 fixedly sleeved on the end of the testing rod 16, and a reciprocating portion for realizing the reciprocating movement of the testing rod 16. The moving direction of the testing rod 16 is along the horizontal direction. The side wall of the sampling tube 3 is provided with a testing hole 18 adapted to the testing rod 16. When the sampling tube 3 is rotated to the opening facing upward, the testing rod 16 is directly opposite to the testing hole 18. The testing rod 16 is away from the position of the sampling tube 3 in the initial position, thereby avoiding the testing rod 16 from affecting the normal operation of the sampling tube 3. In this embodiment, the absorbent paper 17 can of course also use the detection principle of the cobaltous chloride test paper 10 and the color sensor 14. However, the main function of the absorbent paper 17 in this embodiment is that the filter cake cannot squeeze out water, but its interior is in a humid state. At this time, when the sample is pressed in the sampling tube 3, the absorbent paper 17 can still absorb water for the sample in the humid state. The color depth of the absorbent paper 17 in the dry and humid states is different, and only the staff needs to observe.

[0024] The reciprocating part includes a reciprocating electric push rod 28, which is used to control the movement of the test rod 16. When the sampling tube 3 completes sampling and the sampling tube 3 is rotated to an opening facing upward, the end of the test rod 16 is facing the test hole 18, and the reciprocating electric push rod 28 moves the test rod 16 toward the test hole 18. The test rod 16 moves into the test hole 18 and the test rod 16 does not extend out of the test hole 18, and the absorbent paper 17 can just abut against the sample, and the test rod 16 can also play the effect of blocking the test hole 18 to prevent water from being squeezed out of the test hole 18. When the sample begins to be squeezed, the absorbent paper 17 on the test rod 16 is always in contact with the sample. As samples at different positions are squeezed, the absorbent paper 17 contacts samples at different positions, and then the absorbent paper 17 can be fully in contact with the wet sample to determine whether the sample is wet, thereby greatly improving the detection accuracy.

[0025] Reference Figure 1-Figure 3 The cleaning mechanism includes a loosening component for breaking up the sample after extrusion, a drying component for drying the sample, and a scraper component for cleaning the inner wall of the sampling tube 3. The loosening component includes a loosening frame 19 that is lifted and arranged on the extrusion frame 6, a loosening motor 20 fixed on the loosening frame 19, and a loosening leaf 21 that is rotatably arranged on the loosening frame 19. The loosening motor 20 controls the rotation of the loosening leaf 21. The loosening frame 19 and the extrusion rod 7 are respectively located at the two ends of the extrusion frame 6. The lifting and lowering of the loosening frame 19 is also achieved by an electric push rod or a cylinder. The loosening leaf 21 is spiral in this embodiment to facilitate the extrusion. After the test is completed, the extrusion frame 6 is controlled to rotate. After the extrusion motor controls the extrusion frame 6 to rotate 180°, the loosening leaves 21 are opposite to the opening of the sampling tube 3. The opening size of the sampling tube 3 is larger than the size of the loosening leaves 21. At this time, the loosening frame 19 is controlled to descend and the loosening leaves 21 are moved into the sampling tube 3. After the loosening motor 20 controls the loosening leaves 21 to rotate, the samples in the sampling tube 3 are broken up. At this time, it is convenient for the samples to fall from the sampling tube 3. After the loosening leaves 21 are moved to a position away from the sampling tube 3, the sampling tube 3 is controlled to rotate and the opening of the sampling tube 3 is facing downward, and the samples fall from the sampling tube 3.

[0026] The scraper assembly includes a scraper 22 slidably arranged in the sampling tube 3 and a driving part for controlling the reciprocating motion of the scraper 22. The scraper 22 is located close to the extrusion tube 5 in the initial state. The driving part includes two guide rails 23 and a slide rod 24. The two guide rails 23 are respectively fixed at two opposite positions in the sampling tube 3. The two ends of the slide rod 24 are respectively sleeved and slid on the two guide rails 23. The guide rails 23 and the slide rod 24 are made of conductive materials, and the two guide rails 23 are respectively connected to external power sources with opposite positive and negative poles. The scraper 22 is arranged in a ring shape, and the slide rod 24 is also arranged in a circular arc shape. The thickness of the scraper 22 gradually decreases toward the inside of the sampling tube 3, so that the inner wall of the sampling tube 3 can be scraped for sampling. Since the guide rails 23 and the slide rod 24 are both located in the sampling tube 3, the scraper 22 and the extrusion disk 8 are both selected in corresponding shapes to fully adapt to the inner wall of the sampling tube 3.

[0027] In this embodiment, a positive and negative power supply is connected to the same end of the two guide rails 23, and then another positive and negative power supply is connected to the other end of the guide rail 23, and the two ends of the same guide rail 23 are respectively connected to power supplies of different electrodes, so that the reciprocating motion of the slide bar 24 can be realized. In the initial state, the scraper 22 is located close to the extrusion cylinder 5, so when the scraper 22 is unloaded, it is located above the sampling cylinder 3, and when the scraper 22 needs to move, a power supply is turned on at this time, so that the power flows on the two guide rails 23 and the slide bar 24, and the two guide rails 23, the slide bar 24 and the external DC power supply form a closed loop. According to the flow direction of the current and the installation By using the Ampere rule, the directions of the magnetic flux lines of the two guide rails 23 and the slide bar 24 within the range of the energized power supply side can be obtained. Then, by using the left-hand rule, it can be obtained that the direction of the Ampere force exerted on the slide bar 24 is parallel to the guide rail 23 and points to the opening of the sampling tube 3. That is, when the guide rail 23 is energized, the slide bar 24 is acted upon by the Ampere force and moves on the guide rail 23 toward the opening of the sampling tube 3, thereby driving the slide bar 24 and the scraper 22 to move. When the scraper 22 needs to move to the initial position, this power supply can be turned off and another power supply can be turned on. At this time, the movement direction of the slide bar 24 is toward the direction away from the extrusion tube 5, thereby moving the scraper 22 to the initial position.

[0028] Reference Figure 1-Figure 5The drying assembly includes two drying semi-rings 25, a heating element 26, a control unit for controlling the movement of the drying semi-rings 25, and a connecting unit for connecting the drying semi-rings 25 and the sliding rod 24. The two drying semi-rings 25 are adapted to the sampling tube 3. The heating element 26 is arranged in the drying semi-rings 25. The thickness of the drying semi-rings 25 is greater than the thickness of the scraper 22. The two drying semi-rings 25 are adsorbed by two first electromagnets 31. The heating element 26 can be selected from electric heating wires in this embodiment. The control unit includes a control electric push rod 27 and a second electromagnet 32. The second electromagnet 32 ​​and the pair The drying half ring 25 should be adsorbed, and the drying half ring 25 is slidably set on the frame 1. Therefore, the drying half ring 25 is also away from the movement path of the sampling tube 3 in the initial position to avoid affecting the normal operation of the sampling tube 3. When the drying half ring 25 needs to be dried, the electric push rod 27 is controlled to move the drying half ring 25 toward the direction of the sampling tube 3. When the two drying half rings 25 abut, the two drying half rings 25 are adapted to the outer wall of the sampling tube 3. After the drying half rings 25 are in contact, the first electromagnet 31 is energized and the second electromagnet 32 ​​is de-energized. At this time, the two drying half rings 25 are combined together.

[0029] The connecting part includes two magnet blocks 29 and a partition 30. The magnet block 29 is fixed in the sliding rod 24. The sampling tube 3 is provided with a partition for installing the partition 30. Another magnet block 29 is fixed on the inner wall of any drying semi-ring 25. The two magnet blocks 29 are respectively located on both sides of the partition 30 and adsorbed to each other. The drying semi-ring 25 moves with the scraper 22. The partition 30 is made of a material that is convenient for the two magnet blocks 29 to adsorb to each other. The corresponding drying semi-ring 25 is provided with a mounting hole, and the corresponding magnet block 29 is installed in the mounting hole. When the two drying semi-rings 25 are combined together, the two magnet blocks 29 adsorb to each other, thereby realizing the combination of the drying semi-rings 25 and completing the effect of connecting the scraper 22 to the drying semi-ring 25. Since the thickness of the drying semi-ring 25 is greater than the thickness of the scraper 22, the heating element 26 in the drying semi-ring 25 dries the sample on the movement path of the scraper 22. The dried sample is convenient for the scraper 22 to scrape, thereby ensuring the cleanliness of the sampling tube 3.

[0030] The implementation principle of a method for preparing a feed additive for promoting intestinal health of livestock and poultry in an embodiment of the present application is as follows: first, the sampling tube 3 is rotated to a position where the opening faces downward, and the bracket 2 moves downward. When the sampling tube 3 moves toward the filter cake, the sample enters the sampling tube 3. When the sampling tube 3 moves to the bottom end of the filter cake, the bracket 2 and the sampling tube 3 are moved upward until they are separated from the filter cake, and then the rotating motor 4 is used to control the rotation of the sampling tube 3, and the open end of the sampling tube 3 is rotated upward to complete the sampling work.

[0031] When sampling is completed, the sampling tube 3 is rotated to the point where the opening faces upward, that is, facing the squeezing plate 8, and the test paper 10 is pulled under the filter screen 9. The sample in the sampling tube 3 is squeezed out of water by controlling the squeezing rod 7 and the squeezing plate 8. If the sample is not dried, the water is squeezed into the squeezing tube 5. The test paper 10 changes color after encountering the water. The color sensor 14 recognizes that the test paper 10 changes color, and the color sensor 14 triggers the buzzer 15 to sound, proving that the filter cake is not dried; the test rod 16 moves to the test hole 18 and the test is The test rod 16 does not extend out of the test hole 18, and the absorbent paper 17 can just abut against the sample, and the test rod 16 can also block the test hole 18 to prevent water from being squeezed out of the test hole 18. When the sample begins to be squeezed, the absorbent paper 17 on the test rod 16 is always in contact with the sample. As the samples at different positions are squeezed, the absorbent paper 17 contacts with the samples at different positions, and then the absorbent paper 17 can be fully in contact with the wet sample to determine whether the sample is wet, thereby greatly improving the detection accuracy.

[0032] When the two drying half rings 25 are combined together, the two magnet blocks 29 are attracted to each other, thereby achieving the effect of combining the drying half rings 25 and connecting the scraper 22 to the drying half ring 25. Since the thickness of the drying half ring 25 is greater than the thickness of the scraper 22, the heating element 26 in the drying half ring 25 dries the sample on the movement path of the scraper 22. A power supply is turned on to make the power flow on the two guide rails 23 and the slide bar 24. The two guide rails 23, the slide bar 24 and the external DC power supply form a closed loop. According to the direction of current flow and Ampere's law, the direction of the magnetic flux lines of the two guide rails 23 and the slide bar 24 within the range of the energized power supply side can be obtained, and then the left-hand rule can be used to obtain that the direction of the Ampere force exerted on the slide bar 24 is parallel to the guide rail 23 and points to the opening of the sampling tube 3. That is, when the guide rail 23 is energized, the slide bar 24 is acted upon by the Ampere force and moves on the guide rail 23 toward the opening of the sampling tube 3, thereby driving the slide bar 24 and the scraper 22 to move, so that the dried sample is easy to be scraped by the scraper 22, thereby ensuring that the inside of the sampling tube 3 is clean.
