Description

Technical Field

[0001] This invention relates to the field of feed production technology, specifically to a feed production raw material fermentation device. Background Technology

[0002] Feed fermentation is a highly efficient and environmentally friendly biological treatment technology. Through the action of microorganisms, it can significantly improve the nutritional value, palatability, and digestibility of feed, while enhancing animal immunity, reducing feed contamination and spoilage. Fresh materials contain some bacteria and pathogens, and fermenting materials with fermenting agents can kill these bacteria and pathogens, thereby improving the safety of animal feed.

[0003] For example, Chinese Patent No. CN117866739B discloses a clean feed fermentation device and its usage method, including a fermentation tank with a cover installed on its upper side and a feed pipe fixedly installed on the lower side of the cover; a partition plate fixedly installed inside the fermentation tank, with a receiving plate movably connected inside the fermentation chamber for supporting the clean feed; a movable plate movably connected inside the fermentation tank, with grooves evenly distributed on its outer periphery and multiple inclined holes evenly distributed inside the movable plate; and a vertical pipe fixedly installed at the lower end of the movable plate, communicating with the inclined holes and connected to the output end of an external air pump. By vibrating the receiving plate used to receive the fermentation mixture during the fermentation process, the fermentation mixture is kept loose, facilitating sufficient contact between the microorganisms and oxygen, thus achieving efficient fermentation.

[0004] However, when feed ingredients are fermented in the above way, the moisture in the ingredients will sink downwards under the action of gravity. This results in a decrease in the moisture content at the top of the ingredients while the moisture content at the bottom of the ingredients is too high. The uneven distribution of moisture content in the ingredients may reduce the activity of microorganisms in the fermentation tank, thereby reducing the overall fermentation efficiency. In addition, the flat top of the pile has a small contact area with the air, which is not conducive to the aerobic fermentation of the ingredients. Summary of the Invention

[0005] The purpose of this invention is to provide a raw material fermentation device for feed production, so as to solve at least one technical problem existing in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a raw material fermentation device for feed production, comprising a fermentation tank fixedly installed on the ground by a bracket, a top cover fixedly installed on the top of the fermentation tank, and fixing blocks fixedly installed on both sides of the fermentation tank, wherein an annular cavity is formed in the fixing block, the top of the cavity is connected to the top of the fermentation tank, and the bottom of the cavity is connected to the lowest point inside the fermentation tank.

[0007] It also includes a detection component, which is used to detect the moisture content at the top of the material pile inside the fermenter;

[0008] It also includes a turning component, which is used to turn the raw material at the bottom of the fermenter to the top of the pile when the detection component detects that the pile of material in the fermenter is about to stratify, and to make the pile of material form a cone-shaped top.

[0009] Preferably, the turning assembly includes a conveyor belt rotatably installed inside the fixed block, and a conveyor trough connected to the cavity inside the fixed block is fixedly installed on the inner wall of the fermenter. Both of the two conveyor troughs have openings at their close ends, and the openings are positioned at an angle downwards.

[0010] Preferably, the detection component includes a piston rod installed in a perforation in the center of the top cover and capable of vertical reciprocating adjustment. An elastic water-absorbing ring is fixedly installed on the outer wall of the piston rod. Multiple sets of capillaries are provided on the inner wall of the elastic water-absorbing ring. Conductive carbon black is provided inside the piston rod and contacts and abuts against the capillaries. The conductive carbon black is connected to an external power circuit through a wire embedded in the piston rod.

[0011] Preferably, two sets of fixing rods are fixedly installed on the top surface of the top cover, a fixing frame is fixedly installed on the outer wall of the fixing rod, a fixing cylinder is fixedly connected to the inner wall of the fixing frame, a sliding piston plate is installed inside the fixing cylinder, the bottom end of the piston plate is fixedly connected to the top end of the piston rod, an annular cavity is opened inside the piston rod, a fine hole communicating with the annular cavity is opened on the top surface of the piston plate, and the fixing cylinder above the piston plate is connected to an external air supply device.

[0012] Preferably, a threaded rod is rotatably mounted between the fixed frame and the top cover, and a movable plate that is slidably mounted on the outer wall of the piston rod is fixedly mounted on the outer wall of the fixed rod. The movable plate has a threaded groove that meshes with the threaded rod.

[0013] Preferably, the bottom end of the conductive carbon black is higher than the bottom end of the elastic absorbent ring, and the cross-section of the inner wall of the annular cavity where the conductive carbon black and the bottom end of the elastic absorbent ring are in contact is arc-shaped.

[0014] Preferably, a triangular-section base plate is fixedly installed at the bottom of the fermenter, and the bottom ends of both sides of the base plate are respectively connected to the annular cavities in the two fixed blocks.

[0015] Preferably, a baffle is vertically slidably installed in the communication between the fermentation tank and the bottom of the annular cavity in the fixed block, and an electromagnet is fixedly installed in the inner wall of the fermentation tank above the baffle. The top of the baffle is provided with a magnetic block that can attract or repel the electromagnet.

[0016] Preferably, the top cover is fixedly connected to the top of the fermenter via a flange connection.

[0017] Preferably, the bottom plate surface is provided with a one-way air supply hole.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] I. This invention, through the cooperation between the detection component and the turning component, can turn the material pile in the fermentation tank in a timely manner when stratification is about to occur. This allows the material with higher moisture content at the bottom to be turned over to the top material with lower moisture content. While ensuring the moisture content of the material at the top, it avoids the bottom material having too high a moisture content, which would reduce the air density and cause the material at the bottom of the pile to ferment in an anaerobic environment. This would lead to the proliferation of anaerobic bacteria, which would lower the pH value at the bottom of the material and damage the breeding environment of aerobic bacteria, preventing the material from undergoing sufficient aerobic fermentation.

[0020] Second, this invention uses a motor-driven conveyor to transport raw materials from the bottom of the pile to the top, and then discharges them through conveyor troughs on both sides. This allows raw materials with high moisture content to be squeezed and collided with each other during the descent. After crushing large pieces of raw materials, the raw materials fall onto the surface of the pile and form a conical top. This not only allows the raw materials to be further crushed and layered as they roll along the cone surface, but also increases the surface area of ​​the top of the pile to increase the contact area between the raw materials and oxygen, thereby further improving the aerobic fermentation efficiency of the raw materials in the fermenter.

[0021] Third, this invention utilizes the reciprocating sliding of the piston plate within the fixed cylinder to drive changes in air pressure, thereby enhancing the water absorption capacity of the piston rod during its descent to inspect the top of the material pile. Simultaneously, as the piston rod rises, hot air is blown into the annular cavity to dry the conductive carbon black and the elastic water-absorbing ring. This allows the piston rod to repeatedly inspect the material pile. Furthermore, the expansion and contraction of the elastic water-absorbing ring helps the moisture-containing raw materials adhering to its outer wall detach from the ring. After the raw materials adhering to the outer wall of the elastic water-absorbing ring are dried under the action of the hot air, the expansion and contraction of the ring cause cracks in the dried material, making it easier for it to detach from the outer wall of the ring. This prevents the raw materials from clogging the ring and causing the conductive carbon black to become desensitized to the moisture content of the raw materials. Attached Figure Description

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 8 The present invention provides a technical solution: a raw material fermentation device for feed production, including a fermentation tank 1 fixedly installed on the ground by a bracket, a top cover 3 fixedly installed on the top of the fermentation tank 1, and fixing blocks 2 fixedly installed on both sides of the fermentation tank 1. An annular cavity is opened in the fixing block 2, the top of the cavity is connected to the top of the fermentation tank 1, and the bottom of the cavity is connected to the lowest point inside the fermentation tank 1.

[0033] It also includes a detection component, which is used to detect the moisture content at the top of the material pile inside fermenter 1;

[0034] It also includes a turning component, which is used to turn the raw material at the bottom of the fermenter 1 to the top of the pile when the detection component detects that the pile in the fermenter 1 is about to stratify, and to make the pile form a cone-shaped top.

[0035] In use, the raw materials are first poured into the fermentation tank 1 through the inlet on the top cover 3. The raw materials are then allowed to stand and fermentation begins. The detection component continuously monitors the raw materials in the fermentation tank 1. If the detection component detects that the moisture content of the material pile in the fermentation tank 1 is not insufficient (i.e., no stratification or impending stratification), the fermentation can continue until complete. Then, the fermented feed materials are removed through the outlet on the inner wall at the bottom of the fermentation tank 1, completing the fermentation process. The fermentation tank 1 is then cleaned, and the above process is repeated to produce feed materials in batches. If the detection component detects that the moisture content of the material pile in the fermentation tank 1 is insufficient, the fermentation process can continue. If the moisture content at the top of the material pile drops below a preset value, it indicates that the material pile is about to separate into layers. To ensure that the moisture content in the material pile in fermenter 1 remains uniform, the material pile can be turned over by the turning component. This allows the raw materials with higher moisture content at the bottom of the pile to be turned back to the top, and the moisture at the top gradually settles under the action of gravity, thus wetting the raw materials with low moisture content. This redistributes the moisture in the entire material pile evenly, improves the activity of microorganisms in fermenter 1, and achieves the purpose of increasing the overall fermentation rate. Furthermore, the cone-shaped top of the material pile increases the contact area between the top surface of the material pile and oxygen in the air, further improving the fermentation efficiency.

[0036] In this way, through the cooperation between the detection component and the turning component, the raw material pile in fermenter 1 can be turned in time when it is about to stratify. This turns the raw material with higher moisture content at the bottom to the top of the raw material with lower moisture content. While ensuring the moisture content of the raw material at the top, it avoids the bottom from having too high moisture content, which would reduce the air density and cause the raw material at the bottom of the pile to ferment in an anaerobic environment. This would lead to the proliferation of anaerobic bacteria, which would lower the pH value at the bottom of the raw material and damage the breeding environment of aerobic bacteria, preventing the raw material from undergoing sufficient aerobic fermentation.

[0037] Furthermore, the turning assembly includes a conveyor 11 rotatably installed inside the fixed block 2, and a conveyor trough 15 connected to the cavity inside the fixed block 2 is fixedly installed on the inner wall of the fermentation tank 1. Both conveyor troughs 15 have openings at their close ends, and the openings are positioned at an angle downwards.

[0038] A specific implementation of the turning component is provided based on the above embodiments. See details below. Figure 2 When an external drive structure (such as a motor) drives the conveyor 11 to rotate, the spiral fins on the conveyor 11 can draw the raw material from the bottom of the fermenter 1 upwards and discharge it from the two conveying troughs 15 respectively. See details. Figure 8When the raw materials at the bottom are conveyed to the conveying trough 15 and discharged from the opening, the raw materials on both sides collide and are squeezed due to their opposing transport directions. This causes the raw materials that are squeezed and mixed together to break up due to the impact, keeping the raw materials in a loose state. This not only makes it easier for the raw materials to absorb moisture, but also allows a large amount of air to be mixed into the raw materials to aid fermentation. After the raw materials on both sides collide and fall to the top of the pile, due to the high moisture content and the large friction between them, the raw materials can accumulate on the top of the pile. After accumulating to a certain height, they will roll outwards under the influence of gravity until they form a pile. Figure 8 The cone-shaped top shown in the diagram allows newly fallen raw materials to roll along the surface of the cone after its formation, further dispersing the raw material blocks into a layered aggregate state, thereby increasing the fluffiness of the raw materials and thus increasing the fermentation rate.

[0039] In this way, the conveyor 11 driven by the motor transports the raw materials from the bottom of the pile to the top of the pile, and then discharges them through the conveyor troughs 15 on both sides. This allows the raw materials with high moisture content to squeeze and collide with each other during the descent. After crushing the large pieces of raw materials, the raw materials fall onto the surface of the pile and form a conical top. This not only allows the raw materials to be further crushed and layered as they roll along the cone surface, but also increases the surface area of ​​the top of the pile to increase the contact area between the raw materials and oxygen, thereby further improving the aerobic fermentation efficiency of the raw materials in the fermenter 1.

[0040] Furthermore, the detection assembly includes a piston rod 9 installed in a perforation in the center of the top cover 3 and capable of vertical reciprocating adjustment. An elastic water-absorbing ring 18 is fixedly installed on the outer wall of the piston rod 9. Multiple sets of capillaries 20 are provided on the inner wall of the elastic water-absorbing ring 18. Conductive carbon black 19 is provided inside the piston rod 9 and contacts and abuts against the capillaries 20. The conductive carbon black 19 is connected to an external power circuit through a power wire 17 embedded in the piston rod 9.

[0041] As can be seen from the above implementation method, when the external structure drives the piston rod 9 to slide back and forth inside the fermentation tank 1, see the specific details. Figure 7(Point a in the figure is the cone-shaped surface at the top of the material pile). When the piston rod 9 slides down to insert into the material pile a certain distance, it can absorb the moisture in the raw material through the elastic water-absorbing ring 18. The moisture in the elastic water-absorbing ring 18 enters the conductive carbon black 19 through the capillary tube 20, which reduces the resistance and increases the conductivity of the conductive carbon black 19 after absorbing the water. The ammeter is in the same electrical circuit as the conductive carbon black 19. If the ammeter value is not lower than the preset value, it indicates that there is no obvious stratification of the moisture in the material pile. If the ammeter value is lower than the preset value, it indicates that the moisture at the top of the material pile has decreased too much and the moisture has obviously settled. At this time, the turning component can be driven to turn the material pile, turning the moisture-rich material at the bottom to the top of the material, so that the moisture in the material can be redistributed, avoiding the top of the material from being too dry, which would reduce the activity of microorganisms and cause the material to ferment incompletely and unevenly.

[0042] In this way, the piston rod 9 is intermittently driven downward by the external drive structure to be inserted into the material pile. Through the cooperation between the elastic water absorption ring 18 and the conductive carbon black 19, it is possible to intermittently detect whether there is a significant drop in the moisture content at the top of the material pile. The material pile is then turned over in time by the turning component to ensure that the fermentation rate and microbial activity in the fermenter 1 are kept at the best level, so as to improve the fermentation rate and fermentation quality.

[0043] It is worth mentioning that, since the top of the material pile is conical, the moisture deposition is most obvious at the top of the pile. Inserting the piston rod 9 into the material pile along the top of the cone can not only allow the detection component to detect changes in the moisture content of the material pile in advance, but also help improve the detection accuracy of the detection component, so as to ensure that the monitoring results of the raw materials can accurately reflect the moisture deposition status of the raw materials.

[0044] Furthermore, two sets of fixing rods 4 are fixedly installed on the top surface of the top cover 3. A fixing frame 5 is fixedly installed on the outer wall of the fixing rod 4. A fixing cylinder 8 is fixedly connected to the inner wall of the fixing frame 5. A sliding piston plate 14 is installed inside the fixing cylinder 8. The bottom end of the piston plate 14 is fixedly connected to the top end of the piston rod 9. An annular cavity 16 is opened inside the piston rod 9. A fine hole communicating with the annular cavity 16 is opened on the top surface of the piston plate 14. The fixing cylinder 8 above the piston plate 14 is connected to the external air supply equipment.

[0045] As can be seen from the above embodiments, when the piston plate 14 slides up and down reciprocally within the fixed cylinder 8, see the details below. Figure 4 When the piston plate 14 and piston rod 9 slide downwards together, the air pressure in the fixed cylinder 8 above the piston plate 14 decreases, and a negative pressure is generated in the annular cavity 16 through the fine holes on the top surface of the piston plate 14. This allows the piston rod 9, inserted into the top of the material pile, to draw water from the material pile through the elastic water-absorbing ring 18, and then into the conductive carbon black 19 through the capillary tube 20. See details. Figure 7At this time, the elastic absorbent ring 18 contracts inward under suction, causing the capillary 20 to fit tightly against the conductive carbon black 19, further improving the accuracy of the test results. When the piston plate 14 and piston rod 9 slide upward together, the air pressure in the fixed cylinder 8 above the piston plate 14 rises, and airflow is slowly blown into the annular cavity 16 through the fine holes on the top surface of the piston plate 14. The airflow in the annular cavity 16 dries the conductive carbon black 19 and the elastic absorbent ring 18. See details... Figure 4 At this time, the elastic water-absorbing ring 18 expands outward, so that the capillary 20 completely detaches from the surface of the conductive carbon black 19, thus avoiding the capillary 20 from blocking the surface of the conductive carbon black 19 and causing moisture residue on the surface of the conductive carbon black 19, which would result in distorted test results.

[0046] In this way, the piston plate 14 slides up and down in the fixed cylinder 8, causing changes in the air pressure inside the fixed cylinder 8. This increases the water absorption capacity of the piston rod 9 when it descends to detect the top of the material pile. When the piston rod 9 rises, it blows air into the annular cavity 16 to dry the conductive carbon black 19 and the elastic water-absorbing ring 18. This allows the piston rod 9 to repeatedly detect the material pile. The expansion and contraction of the elastic water-absorbing ring 18 helps the water-containing raw material adhering to the outer wall of the elastic water-absorbing ring 18 to detach from the elastic water-absorbing ring 18. After the raw material adhering to the outer wall of the elastic water-absorbing ring 18 dries under the action of the airflow, the expansion and contraction of the elastic water-absorbing ring 18 can cause the dried raw material to crack, making it easier to detach from the outer wall of the elastic water-absorbing ring 18. This prevents the raw material from clogging the elastic water-absorbing ring 18 and causing the conductive carbon black 19 to become desensitized to the moisture content of the raw material.

[0047] In order to avoid the airflow from contaminating the microbial community in the fermenter 1, the external air supply equipment can provide sterilized clean airflow into the fixed cylinder 8, and the fixed cylinder 8 is equipped with a heating device to heat the clean airflow, so as to improve the drying capacity of the conductive carbon black 19 and the elastic water-absorbing ring 18.

[0048] Furthermore, a threaded rod 6 is rotatably installed between the fixed frame 5 and the top cover 3, and a movable plate 7 is fixedly installed on the outer wall of the piston rod 9 and slidably installed on the outer wall of the fixed rod 4. The movable plate 7 has a threaded groove that meshes with the threaded rod 6.

[0049] The above embodiment provides a specific implementation method for driving the piston rod 9 to reciprocate. See details below. Figure 1 When an external drive structure (such as a motor) drives the threaded rod 6 to rotate, the threaded rod 6 can drive the moving plate 7 to slide up and down along the outer wall of the fixed rod 4 through the threaded groove in the moving plate 7, thus completing the up and down reciprocating movement of the piston rod 9. The reciprocating screw can increase the stability of the piston rod 9 during movement.

[0050] Furthermore, the bottom end of the conductive carbon black 19 is higher than the bottom end of the elastic water-absorbing ring 18, and the cross-section of the inner wall of the annular cavity 16 that is in contact with the bottom end of the conductive carbon black 19 and the elastic water-absorbing ring 18 is arc-shaped.

[0051] As can be seen from the above embodiments, by making the bottom end of the conductive carbon black 19 higher than the bottom end of the elastic water-absorbing ring 18, and the cross-section of the inner wall of the annular cavity 16 that is in contact with the bottom end of the conductive carbon black 19 and the elastic water-absorbing ring 18 is arc-shaped (see details). Figure 4 This completely eliminates dead corners within the annular cavity 16. It prevents the hot airflow from generating eddies in the annular cavity 16 after passing over the conductive carbon black 19, which would cause the hot airflow velocity to decrease and thus reduce the drying efficiency. At the same time, it also prevents dead corners within the annular cavity 16 from providing residual space for moisture absorbed by the elastic water-absorbing ring 18, ensuring that the moisture evaporates completely and avoids affecting subsequent test results.

[0052] Furthermore, a triangular-section base plate 10 is fixedly installed at the bottom of the fermenter 1, and the bottom ends of both sides of the base plate 10 are respectively connected to the annular cavities in the two fixing blocks 2. Furthermore, the surface of the base plate 10 is provided with a one-way gas delivery hole.

[0053] As can be seen from the above embodiments, by setting the cross-section of the bottom plate 10 to be triangular, the raw materials can slide down to the lowest points on both sides after being piled on the surface of the bottom plate 10, ensuring that all the raw materials can be turned over when the conveyor 11 rotates, avoiding the presence of raw materials that cannot be turned over at the bottom of the fermentation tank 1, improving the uniformity of the material pile. Furthermore, since the surface of the bottom plate 10 is provided with one-way air supply holes, an oxygen supply device can also be installed in the space below the bottom plate 10 to provide hydrolyzed oxygen to the raw materials at the bottom of the material pile, preventing the fermentation efficiency and quality at the bottom of the material pile from decreasing.

[0054] Furthermore, a baffle 12 is vertically slidably installed in the connection between the bottom of the annular cavity of the fermentation tank 1 and the fixed block 2. An electromagnet 13 is fixedly installed in the inner wall of the fermentation tank 1 above the baffle 12. A magnetic block that can attract or repel the electromagnet 13 is provided at the top of the baffle 12.

[0055] As can be seen from the above implementation method, when the detection component detects that the moisture content in the pile is evenly distributed, the electromagnet 13 can push the baffle 12 down to seal the connection between the bottom of the annular cavity in the fermentation tank 1 and the fixed block 2, and continue to rotate the conveyor 11 to completely drain the raw material in the annular cavity in the fixed block 2, so as to prevent the raw material remaining in the fixed block 2 from creating a fermentation environment different from that in the fermentation tank 1, and changing the fermentation environment in the fermentation tank 1 during the subsequent turning. When the detection component detects that the moisture content in the pile has deposited or stratified, the electromagnet 13 can pull the baffle 12 up to release the seal between the fermentation tank 1 and the fixed block 2.

[0056] Furthermore, the top cover 3 is fixedly connected to the top of the fermenter 1 via a flange connection.

[0057] As can be seen from the above implementation method, the top cover 3 is fixedly connected to the top of the fermentation tank 1 through a flange connection, so that the top cover 3 can be opened directly during feeding or unloading, and feeding or unloading can be done quickly respectively.

[0058] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed directly based on existing technical knowledge without any doubt. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0059] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
