Description

Technical Field

[0001] The invention relates to the technical field of feed production, in particular to a raw material fermentation device for feed production. Background Art

[0002] Feed fermentation is an 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 the immunity of animals and reducing feed contamination and deterioration. Fresh materials may contain some bacteria and pathogens. Using fermentation agents to ferment materials can kill these bacteria and pathogens, thereby improving the safety of animal material feeding.

[0003] For example, Chinese patent number CN117866739B discloses a clean feed fermentation device and a method of using the same, including a fermentation tank, a cover body installed on the upper side, and a feed pipe fixedly installed on the lower side of the cover body; a partition plate fixedly installed inside the fermentation tank, located inside the fermentation chamber and movably connected to a receiving plate for supporting clean feed; and a movable plate movably connected inside the fermentation tank, the outer sides of the movable plate are evenly provided with grooves, the inside of the movable plate is evenly provided with a plurality of inclined holes, and a vertical pipe fixedly installed at the lower end of the movable plate, the inside of the vertical pipe is connected to the inclined holes, and the vertical pipe is connected to the output end of the external air pump. During the fermentation process, the receiving plate used to receive the fermentation mixture is vibrated to ensure the loose state of the fermentation mixture, so as to facilitate the full contact between the strain and oxygen and achieve efficient fermentation.

[0004] However, when the feed raw materials are fermented in the above manner, the moisture in the raw materials will settle downwards under the action of gravity, causing the moisture content at the top of the raw materials to decrease while causing the moisture content at the bottom of the raw materials to be excessive. The uneven distribution of moisture content in the raw materials may lead to reduced microbial activity in the fermentation tank, thereby reducing the overall efficiency of the fermentation. In addition, the contact area between the flat top of the pile and the air is small, which is not conducive to aerobic fermentation of the raw materials. Summary of the invention

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

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

[0017] Preferably, a one-way air delivery hole is provided on the surface of the bottom plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention can timely turn the raw material pile in the fermentation tank when stratification is about to occur through the cooperation between the detection component and the compost turning component, so that the raw material with a higher water content at the bottom is turned over above the raw material with a lower water content at the top. While ensuring the water content of the raw material at the top, it avoids the reduction of air density due to excessive water content at the bottom, so that the raw material at the bottom of the pile is fermented in an anaerobic environment, the anaerobic bacteria reproduce in large quantities, reduce the pH value at the bottom of the raw material, damage the reproduction environment of the aerobic bacteria, and make it impossible for the raw material to be fully aerobically fermented.

[0020] 2. The present invention drives the conveying dragon to transport the raw materials at the bottom of the pile to the top of the pile through a motor, and then discharges them through the conveying troughs on both sides, so that the raw materials with higher water content can squeeze and collide with each other during the descent, and form a conical pile top on the surface of the pile after the large pieces of raw materials are squeezed and crushed. Not only can the raw materials be further broken and stratified in the process of rolling along the cone surface, but the contact area between the raw materials and oxygen can also be increased by increasing the surface area of ​​the pile top, thereby further improving the aerobic fermentation efficiency of the raw materials in the fermentation tank.

[0021] 3. The present invention drives the air pressure change in the fixed cylinder when the piston plate slides back and forth up and down in the fixed cylinder, thereby improving the water absorption capacity of the piston rod when it descends to detect the top of the material pile, and blows a hot air flow into the annular cavity when the piston rod rises to dry the conductive carbon black and the elastic water-absorbing ring, so that the piston rod can repeatedly detect the material pile, and the expansion and contraction of the elastic water-absorbing ring can help the water-containing raw materials adhered to the outer wall of the elastic water-absorbing ring to separate from the elastic water-absorbing ring. When the raw materials adhered to the outer wall of the elastic water-absorbing ring are dried under the action of the hot air flow, the expansion and contraction of the elastic water-absorbing ring can cause the dry raw materials to crack, making it easier to separate from the outer wall of the elastic water-absorbing ring, thereby avoiding clogging of the elastic water-absorbing ring by the raw materials, causing the conductive carbon black to be desensitized to the water content in the raw materials.

DETAILED DESCRIPTION

[0031] 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.

[0032] See also Figures 1 to 8 The present invention provides a technical solution: a raw material fermentation device for feed production, comprising a fermentation tank 1 fixedly mounted on the ground by a bracket, a top cover 3 fixedly mounted on the top of the fermentation tank 1, fixed blocks 2 fixedly mounted on both sides of the fermentation tank 1, an annular cavity is opened in the fixed 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 in the fermentation tank 1;

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

[0034] It also includes a pile turning component, which is used to turn the raw materials 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 be stratified, and form a conical pile top.

[0035] When the device is in use, the raw materials are first poured into the fermentation tank 1 through the feed inlet opened on the top cover 3, and then the raw materials are left to stand to start fermentation, and the raw materials in the fermentation tank 1 are continuously detected by the detection component. If the detection component detects that the material pile in the fermentation tank 1 is not lacking in moisture, that is, no stratification or imminent stratification occurs, the material pile can be fermented completely, and the fermented feed raw materials can be taken out through the discharge port opened on the inner wall of the bottom end of the fermentation tank 1 to complete the fermentation of the feed raw materials. Then, the fermentation tank 1 is cleaned and the above process is repeated to carry out batch fermentation production of the feed raw materials. If the detection component detects that there is no moisture in the fermentation tank 1, the fermentation tank 1 can be used for batch fermentation production. When the moisture content at the top of the pile drops below a preset value, it indicates that the pile is about to be stratified. To ensure that the moisture in the pile in the fermenter 1 remains uniform, the pile can be turned by the pile turning assembly, so that the raw materials with higher moisture content at the bottom of the pile are turned to the top again, and the moisture on the top gradually settles under the action of gravity, so as to wet the raw materials lacking in water content, so that the moisture of the whole pile is evenly redistributed, thereby improving the activity of microorganisms in the fermenter 1, so as to achieve the purpose of improving the overall fermentation rate. In addition, the conical top of the pile can increase the contact area between the top of the pile and the oxygen in the air, thereby further improving the fermentation efficiency.

[0036] In this way, through the cooperation between the detection component and the compost turning component, the raw material pile in the fermentation tank 1 can be turned in time when stratification is about to occur, so that the raw material with a higher water content at the bottom is turned over to the top of the raw material with a lower water content at the top. While ensuring the water content of the raw material on the top, it is avoided that the air density is reduced due to excessive water content at the bottom, so that the raw material at the bottom of the pile is fermented in an anaerobic environment, the anaerobic bacteria multiply in large numbers, reduce the pH value at the bottom of the raw material, damage the breeding environment of the aerobic bacteria, and make it impossible for the raw material to be fully aerobically fermented.

[0037] Furthermore, the compost turning assembly includes a conveying trough 11 rotatably mounted in the fixed block 2, and a conveying trough 15 connected to the cavity in the fixed block 2 is fixedly mounted on the inner wall of the fermentation tank 1. The two conveying troughs 15 are each provided with an opening at one end close to each other, and the opening position is set obliquely downward.

[0038] According to the above embodiment, a specific embodiment of a compost turning assembly is provided. Figure 2 When the external driving structure (such as a motor) drives the conveying sluice 11 to rotate, the raw materials at the bottom of the fermentation tank 1 can be drawn upward through the spiral fins on the conveying sluice 11 and discharged from the two conveying troughs 15 respectively. Figure 8When the raw materials at the bottom are transported to the conveying trough 15 and discharged from the opening, the raw materials on both sides are squeezed and collided due to their transport directions, so that the raw materials that are squeezed and mixed together can be broken by the collision, so that the raw materials remain fluffy, which is not only easy to absorb moisture, but also allows a large amount of air to be mixed into the raw materials to help fermentation. When the raw materials on both sides collide with each other and fall to the top of the pile, the raw materials are rich in moisture and have a large friction force between them, so that the raw materials can be piled up on the top of the pile, and after being piled to a certain height, they are affected by gravity and roll around until they form a pile like Figure 8 After the cone top is formed, the newly fallen raw materials will roll along the surface of the cone top, thereby further dispersing the raw material blocks into a state of layered aggregation, further improving the fluffiness of the raw materials and thereby increasing the fermentation rate.

[0039] In this way, the conveying dragon 11 is driven by a motor to convey the raw materials at the bottom of the pile to the top of the pile, and then discharged through the conveying troughs 15 on both sides, so that the raw materials with higher water content can squeeze and collide with each other during the descent, and the large pieces of raw materials are squeezed and crushed so that the raw materials fall to form a conical pile top on the surface of the pile, which can not only make the raw materials further broken and stratified in the process of rolling along the conical surface, but also increase the contact area between the raw materials and oxygen by increasing the surface area of ​​the pile top, thereby further improving the aerobic fermentation efficiency of the raw materials in the fermentation tank 1.

[0040] Furthermore, the detection component includes a piston rod 9 which is installed in a through hole opened in the center of the top cover 3 and can be adjusted vertically back and forth. An elastic water absorption ring 18 is fixedly installed on the outer wall of the piston rod 9. A plurality of capillaries 20 are provided on the inner wall of the elastic water absorption ring 18. A conductive carbon black 19 which is in contact with and abuts against the capillaries 20 is provided in the piston rod 9. The conductive carbon black 19 is connected to an external power circuit through a power line 17 buried in the piston rod 9.

[0041] According to the above embodiment, when the external structure drives the piston rod 9 to slide back and forth in the fermentation tank 1, the Figure 7(A in the figure is the conical surface at the top of the pile), when the piston rod 9 slides downward to insert into the pile for a distance, the water in the raw material can be absorbed through the elastic water absorption ring 18, and the water in the elastic water absorption ring 18 enters the conductive carbon black 19 through the capillary 20, so that the conductive carbon black 19 after water absorption reduces its resistance and improves its conductivity, which can be measured by an ammeter in the same energized circuit as the conductive carbon black 19. If the value in the ammeter is not lower than the preset value, it indicates that there is no obvious stratification of the water in the pile. If the value in the ammeter is lower than the preset value, it indicates that the water at the top of the pile is reduced too much and the water has obviously settled. At this time, the turning component can be driven to turn the raw material pile, and the water-rich raw material at the bottom of the raw material is turned to the top of the raw material, so that the water in the raw material can be redistributed to avoid the top of the raw material being too dry, resulting in reduced microbial activity, and insufficient and uneven fermentation of the raw material.

[0042] In this way, the piston rod 9 is intermittently driven downward to be inserted into the material pile through the external driving structure, and 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 trend or phenomenon of a substantial decrease in the water content at the top of the material pile, and the material pile is turned in time through the turning assembly to ensure that the fermentation rate and microbial activity in the fermenter 1 are maintained in the best state, so as to achieve the purpose of improving the fermentation rate and fermentation quality.

[0043] It is worth mentioning that since the top of the pile is cone-shaped, the moisture deposition condition is most obvious at the top of the pile. Inserting the piston rod 9 into the pile along the top of the cone can not only enable the detection component to detect the change in the moisture content in the pile in advance, but also help to 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 condition in the raw materials.

[0044] Furthermore, two groups 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 slidable piston plate 14 is installed in 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 in the piston rod 9, a fine hole connected to the annular cavity 16 is opened on the top surface of the piston plate 14, and the fixing cylinder 8 above the piston plate 14 is connected to the external air supply equipment.

[0045] According to the above embodiment, when the piston plate 14 slides back and forth up and down in the fixed cylinder 8, Figure 4 When the piston plate 14 and the piston rod 9 slide downward together, the air pressure in the fixed cylinder 8 above the piston plate 14 will drop, and negative pressure will be generated in the annular cavity 16 through the fine holes on the top surface of the piston plate 14, so that the piston rod 9 inserted into the top of the pile can absorb the water in the pile through the elastic water absorption ring 18, and enter the conductive carbon black 19 through the capillary 20. For details, see Figure 7At this time, the elastic water-absorbing ring 18 is sucked inward and shrinks, so that the capillary 20 and the conductive carbon black 19 are closely attached to each other, further improving the accuracy of the test result. When the piston plate 14 and the piston rod 9 slide upward together, the air pressure in the fixed cylinder 8 above the piston plate 14 rises, and the air flow is slowly blown into the annular cavity 16 through the fine holes on the top surface of the piston plate 14, and the conductive carbon black 19 and the elastic water-absorbing ring 18 are dried by the air flow in the annular cavity 16. For details, see Figure 4 At this time, the elastic water-absorbing ring 18 expands outward, causing the capillary 20 to completely separate from the surface of the conductive carbon black 19, thereby preventing the capillary 20 from blocking the surface of the conductive carbon black 19 and causing moisture to remain on the surface of the conductive carbon black 19, thereby distorting the detection result.

[0046] In this way, the air pressure in the fixed cylinder 8 is changed by the piston plate 14 sliding back and forth up and down in the fixed cylinder 8, thereby improving the water absorption capacity of the piston rod 9 when it descends to detect the top of the material pile, and blowing air into the annular cavity 16 to dry the conductive carbon black 19 and the elastic water-absorbing ring 18 when the piston rod 9 rises, so that the piston rod 9 can repeatedly detect the material pile, and the expansion and contraction of the elastic water-absorbing ring 18 can help the water-containing raw material adhered to the outer wall of the elastic water-absorbing ring 18 to separate from the elastic water-absorbing ring 18. When the raw material adhered to the outer wall of the elastic water-absorbing ring 18 is dried under the action of the airflow, the expansion and contraction of the elastic water-absorbing ring 18 can cause the dry raw material to crack, making it easier to separate from the outer wall of the elastic water-absorbing ring 18, thereby avoiding the raw material clogging the elastic water-absorbing ring 18 and causing the conductive carbon black 19 to be desensitized to the water content in the raw material.

[0047] In order to prevent the airflow from contaminating the bacterial flora in the fermentation tank 1, the external air supply equipment can provide sterilized clean airflow to the fixed cylinder 8, and a heating device is provided in the fixed cylinder 8 to heat the clean airflow, so as to improve the drying capacity of the conductive carbon black 19 and the elastic water absorption ring 18.

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

[0049] According to the above embodiment, a specific embodiment of driving the piston rod 9 to slide back and forth is provided. Figure 1 When an external driving structure (such as a motor) drives the threaded rod 6 to rotate, the threaded rod 6 can drive the movable plate 7 to slide up and down along the outer wall of the fixed rod 4 through the threaded groove in the movable plate 7, thereby completing the up and down reciprocating movement of the piston rod 9, and the stability of the piston rod 9 during movement can be increased through the form of a reciprocating screw.

[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 inner wall cross-section of the annular cavity 16 that is in contact with the bottom ends of the conductive carbon black 19 and the elastic water-absorbing ring 18 is arc-shaped.

[0051] According to the above embodiment, the bottom end of the conductive carbon black 19 is higher than the bottom end of the elastic water-absorbing ring 18, and the inner wall section 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 Figure 4 ) can completely eliminate the dead corners in the annular cavity 16, and avoid the hot air flow from blowing through the conductive carbon black 19 to generate eddy currents in the annular cavity 16, which causes the hot air flow velocity to decrease and thus reduces the drying efficiency. At the same time, it can also avoid the dead corners in the annular cavity 16 providing residual space for the water absorbed by the elastic water absorption ring 18, thereby ensuring that the water is completely evaporated to avoid affecting the subsequent test results.

[0052] Furthermore, a bottom plate 10 with a triangular cross section is fixedly installed at the bottom end of the fermentation tank 1, and the bottom ends of both sides of the bottom plate 10 are respectively connected to the annular cavities in the fixing blocks 2 on both sides. Furthermore, a one-way air transmission hole is provided on the surface of the bottom plate 10.

[0053] According to the above embodiment, by setting the cross-section of the bottom plate 10 to be triangular, the raw materials can be accumulated on the surface of the bottom plate 10 and then slide to the lowest points on both sides, ensuring that all the raw materials can be turned over when the conveying dragon 11 rotates, avoiding the residual raw materials that cannot be turned over at the bottom of the fermentation tank 1, thereby improving the uniformity of the pile. Moreover, since the surface of the bottom plate 10 is provided with a one-way air supply hole, an oxygen supply device can also be arranged in the space below the bottom plate 10 to provide hydrolysis oxygen to the raw materials at the bottom of the pile, thereby avoiding the fermentation efficiency and quality at the bottom of the pile from decreasing.

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

[0055] According to the above embodiment, when the detection component detects that the moisture content in the material pile is evenly distributed, the baffle 12 can be pushed downward by the electromagnet 13 to seal the connection between the fermentation tank 1 and the bottom end of the annular cavity in the fixed block 2, and the conveying dragon 11 can be continued to rotate to completely discharge the raw materials in the annular cavity in the fixed block 2, so as to avoid the residual raw materials in the fixed block 2 from producing a fermentation environment different from that in the fermentation tank 1 through fermentation, and changing the fermentation environment in the fermentation tank 1 in the subsequent turning of the pile. When the detection component detects that the moisture content in the material pile is deposited or stratified, the baffle 12 can be pulled upward by the electromagnet 13 to release the blockage between the fermentation tank 1 and the fixed block 2.

[0056] Furthermore, the top cover 3 is fixedly connected to the top of the fermentation tank 1 through a flange connection.

[0057] According to the above embodiment, the top cover 3 is fixedly connected to the top of the fermentation tank 1 through a flange connection, so the top cover 3 can be directly opened when feeding or unloading, so as to quickly feed or unload respectively.

[0058] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0059] 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.
