Description

Technical Field

[0001] This invention relates to the field of organic fertilizer production technology, and more specifically, to a dual-chamber adaptive fermenter for organic fertilizer. Background Technology

[0002] Organic fertilizer is a type of fertilizer derived from plant and animal residues and processed using specific techniques. It is rich in organic matter and nutrients required by crops. One of its core production steps is aerobic fermentation in a fermentation tank. During this process, microorganisms decompose organic materials, transforming them into stable, harmless, and easily absorbed humus. At the same time, heat is generated to kill pathogens and weed seeds. Scientifically controlled fermentation is the key to ensuring that organic fertilizer is efficient, safe, and of excellent quality.

[0003] To improve the fermentation efficiency and uniformity of organic fertilizer, modern fermentation tanks are often designed with integrated aeration mixing systems. Specifically, the mixing shaft and mixing blades are equipped with dedicated ventilation channels and exhaust holes, which can evenly deliver air (aeration) to the depth of the material while mixing, thereby effectively providing oxygen for aerobic microorganisms, significantly accelerating and improving the fermentation process. During fermentation, the organic material will produce a large amount of water vapor and a small amount of ammonia and other waste gases under the action of microorganisms. These gases rise naturally and are eventually discharged through the exhaust pipe at the top of the tank.

[0004] However, in actual operation, it was found that this top-down overall exhaust method has a structural challenge: the material at the bottom of the fermenter bears the pressure of all the material above, resulting in a more compact material pile with smaller gaps. Although the agitator is working continuously, due to the significant differences in the looseness of the material at the top and bottom and the distance from the exhaust port, the steam and exhaust gas generated at the bottom face greater resistance and have a longer path to escape upwards. This causes the hot and humid gas and exhaust gas in the bottom area to easily remain in the compact material layer, resulting in repeated and excessive hot and humid fumigation of the local material. This uneven gas environment may not only affect the activity of the microbial community at the bottom, causing uneven fermentation, but may also affect the quality of the final fertilizer due to local anaerobic or excessive hot and humid conditions. Summary of the Invention

[0005] This invention provides a dual-chamber adaptive fermenter for organic fertilizer, which solves the problems mentioned in the background art by using a vertical pipe with an air inlet, namely: greater resistance to the upward escape of steam and waste gas and uneven fermentation.

[0006] To achieve the above objectives, a dual-chamber adaptive fermentation tank for organic fertilizer includes a tank body with a hollow shaft installed inside. Stirring blades are installed on the outer wall of the hollow shaft. A longitudinally arranged vertical pipe is provided inside the tank body, connected to the hollow shaft and located within the gap between two adjacent stirring blades. Multiple equally spaced air inlets are provided on the outer wall of the vertical pipe, with the diameter of the air inlets gradually decreasing from the lower part to the upper part of the vertical pipe. The air inlets are located on the side of the vertical pipe opposite to the direction of rotation of the stirring blades. An exhaust pipe is connected to the top of the vertical pipe. A telescopic part is provided at the top of the hollow shaft, which drives the vertical pipe to intermittently move closer to or away from the inner wall of the tank body.

[0007] In the above technical solution, the telescopic part includes a crossbar fixedly connected to the top side wall of the hollow shaft, a slide table slidably mounted on the crossbar, the vertical tube connected to the slide table, and a telescopic device parallel to the crossbar installed on the top of the vertical tube. The telescopic end of the telescopic device is fixedly connected to the slide table and is used to drive the vertical tube to reciprocate laterally.

[0008] Based on the above, a groove is provided on the side of the vertical tube facing away from the direction of rotation of the stirring blades, and a conical head is provided on the other side of the vertical tube. The air inlet is located in the groove. The two sides of the vertical tube facing the hollow shaft and the tank are arc-shaped to reduce the resistance during the movement of the vertical tube.

[0009] Secondly, the vertical tube is slidably mounted on the slide table, and an L-shaped frame is connected to the top of the slide table. A spring is installed between the top of the vertical tube and the L-shaped frame. The slide table is provided with a lifting part that intermittently lifts the vertical tube. The lifting part includes a rotating shaft fixedly connected to the slide table. An inclined rocker arm is fixedly installed on the rotating shaft. A limiting plate is fixedly connected to the vertical tube. When the rocker arm is tilted downward, the other end of the rocker arm lifts the limiting plate upward, so as to make the vertical tube reciprocate up and down while stirring.

[0010] Furthermore, a piston rod is fixedly connected to the upper part of the L-shaped frame, and the lower end of the piston rod is sleeved inside the upper port of the vertical pipe. When the vertical pipe moves upward, the piston rod is pushed towards the inner bottom of the vertical pipe and blocks the port of the exhaust pipe to realize the automatic unblocking of the air intake.

[0011] Furthermore, the hollow shaft has an inner hole in its inner wall and an upper annular gas collecting groove communicating with the inner hole. The output end of the exhaust pipe extends into the upper annular gas collecting groove. The lower end of the hollow shaft has a lower annular gas collecting groove communicating with the lower end of the inner hole. The outer wall of the hollow shaft is connected to a lower pipe communicating with the lower annular gas collecting groove, which facilitates the recovery and utilization of the temperature of the exhaust gas.

[0012] Therefore, by setting up a rotatable independent vertical pipe with its air inlet directly penetrating into the material layer, targeted exhaust can be achieved for the tightly compacted material at the bottom of the tank. This significantly shortens the exhaust gas escape path at the bottom, thereby improving the microenvironment of bottom fermentation and enhancing overall uniformity.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. In this dual-chamber adaptive fermentation tank for organic fertilizer, a rotatable independent vertical pipe is installed in the stirring zone. Its air inlet directly penetrates the material layer. In particular, the larger diameter air inlet at the bottom of the vertical pipe allows for targeted venting of the tightly compacted material at the bottom of the tank. This significantly shortens the escape path of exhaust gas from the bottom, directly alleviating the retention and excessive fumigation of humid and hot gases at the bottom, thereby improving the fermentation microenvironment at the bottom and enhancing overall uniformity.

[0015] 2. In this dual-chamber adaptive fermentation tank for organic fertilizer, the vertical pipe not only revolves with the stirring, but also undergoes intermittent lateral displacement through the telescopic mechanism. This expands the working area of ​​the air inlet in the tank from a fixed point to a dynamically changing three-dimensional space, which can periodically stir and penetrate material layers of different densities, promoting the overall uniform exchange and discharge of gas in the tank.

[0016] 3. In this dual-chamber adaptive fermentation tank for organic fertilizer, by placing the air inlet on the backflow side of the vertical pipe and equipping it with a filter screen, combined with the unique arrow-shaped cross-section and groove design of the vertical pipe, a local low-pressure zone is naturally formed during stirring, reducing the adhesion of raw materials. When the vertical pipe rises and falls periodically, the internal piston structure can temporarily close the exhaust pipe, causing the air pressure inside the pipe to rise and the gas to be ejected from the air inlet in the opposite direction, realizing automatic clearing of blockages, ensuring continuous and stable exhaust capacity, and guaranteeing the fermentation effect during long-term operation.

[0028] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0029] Because the material at the bottom of the tank is more tightly compressed, the resistance to the escape of exhaust gas is greater and the path is longer, which can easily lead to the retention of hot and humid gases and cause excessive fumigation of local materials. This not only affects the activity of microorganisms at the bottom and causes uneven fermentation, but may also cause local anaerobic or excessive hot and humid conditions, which can damage the quality of the finished fertilizer.

[0030] Therefore, in view of the above-mentioned problems, the present invention provides a dual-chamber adaptive fermentation tank for organic fertilizer, with reference to... Figures 1-3As shown, the tank 1 includes a hollow shaft 2 installed inside. The top and bottom of the tank 1 are respectively provided with a feed inlet and a discharge outlet. The outer wall of the hollow shaft 2 is equipped with stirring blades 3. The bottom of the tank 1 is provided with a drive source for driving the hollow shaft 2 to rotate. The drive source is a hydraulic device or a motor. The tank 1 is provided with a vertically arranged vertical pipe 6, which is parallel to the hollow shaft 2 and connected to the hollow shaft 2. The vertical pipe 6 is located in the gap between two adjacent stirring blades 3. The outer wall of the vertical pipe 6 is provided with multiple air inlets 7 arranged at equal intervals. The diameter of the multiple air inlets 7 gradually decreases from the bottom to the top of the vertical pipe 6. The air inlets 7 are provided with a filter screen for filtering raw materials. The air inlets 7 are opened on the side of the vertical pipe 6 opposite to the direction of rotation of the stirring blades 3. The top of the vertical pipe 6 is connected to an exhaust pipe 12. The top of the hollow shaft 2 is provided with a telescopic part, which is used to drive the vertical pipe 6 to intermittently move closer to or away from the inner wall of the tank 1.

[0031] During production, the organic fertilizer raw materials are placed in the tank 1. When the hollow shaft 2 drives the stirring blades 3 to stir, it will synchronously drive the vertical pipe 6 connected to it to rotate in the tank 1. During the stirring process, some of the steam and waste gas generated by the raw materials can directly enter the pipe through the air inlet 7 opened on the side wall of the vertical pipe 6, and then be discharged through the exhaust pipe 12 at the top of the vertical pipe 6.

[0032] The main advantage of this design is that the rotating vertical pipe 6 significantly expands the effective working area of ​​the air inlet 7 inside the tank. This not only enhances the overall mixing effect of the material, but also ensures the exhaust efficiency, effectively reducing the accumulation of steam and exhaust gas at the bottom of the tank 1, thereby improving the fermentation quality of organic fertilizer.

[0033] In addition, the diameter of the multiple air inlets 7 is designed to gradually decrease from the bottom to the top of the vertical pipe 6. This structure allows the tightly packed material at the bottom of the tank with small gaps to achieve a more similar exhaust efficiency to the looser material at the top of the tank with larger gaps, thereby alleviating the problem of poor exhaust at the bottom.

[0034] To prevent raw materials or liquids from directly entering the vertical pipe 6 through the air inlet 7 and causing blockage, in actual production, raw materials with lower moisture content, such as straw or other pre-dried raw materials, should be given priority.

[0035] During the exhaust process, the intermittent movement of the telescopic part causes the vertical pipe 6 to move intermittently closer to or further away from the inner wall of the tank 1. This gives the air inlet 7 on the vertical pipe 6 a larger dynamic working range, thereby further improving the overall exhaust efficiency and stirring effect.

[0036] Reference Figure 3 and Figure 4The telescopic part includes a crossbar 4 fixedly connected to the top side wall of the hollow shaft 2. A slide table 13 is slidably installed on the crossbar 4. The vertical tube 6 is connected to the slide table 13. A telescopic device 15 parallel to the crossbar 4 is installed on the top of the vertical tube 6. The telescopic device 15 is an electric telescopic rod or a hydraulic cylinder. The telescopic end of the telescopic device 15 is fixedly connected to the slide table 13.

[0037] When it is necessary to control the vertical pipe 6 to move back and forth laterally, the slide table 13 can be driven by the telescopic device 15 to slide back and forth along the crossbar 4. The movement of the slide table 13 can synchronously drive the vertical pipe 6 connected to it, so as to realize its lateral back and forth movement inside the entire tank 1.

[0038] Reference Figure 5 and Figure 6 The vertical tube 6 has a groove 8 on the side facing away from the direction of rotation of the stirring blade 3. The other side of the vertical tube 6 has a conical head 10. The air inlet 7 is located in the groove 8. The two sides of the vertical tube 6 facing the hollow shaft 2 and the tank 1 are arc-shaped surfaces 11, which makes the axial cross-section of the vertical tube 6 resemble an arrow.

[0039] When the vertical tube 6 is stirring and moving laterally inside the tank 1, its conical head 10 structure helps to reduce the fluid resistance encountered during the rotation and stirring process. At the same time, the arc-shaped surface 11 provided on the surface of the vertical tube 6 can effectively reduce the resistance encountered during its lateral movement, making the movement smoother.

[0040] In addition, during the stirring process, the groove 8 on the surface of the vertical tube 6 makes it easy to form a relatively stable hollow area in the groove, making it difficult for the raw material to quickly fill the groove 8. This design can effectively prevent the raw material from accumulating and blocking at the port of the air inlet 7, thereby ensuring that the exhaust channel remains unobstructed and maintaining efficient exhaust performance.

[0041] Reference Figure 6 and Figure 9 As shown, the vertical tube 6 is longitudinally slidably mounted on the slide table 13. An L-shaped frame 22 is connected to the top of the slide table 13. A spring 14 is installed between the top of the vertical tube 6 and the L-shaped frame 22. The slide table 13 is provided with a lifting part that intermittently lifts the vertical tube 6. The lifting part includes a rotating shaft 23 fixedly connected to the slide table 13. An inclined rocker plate 24 is fixedly installed on the rotating shaft 23. A limiting plate 25 is fixedly connected to the vertical tube 6. When the rocker plate 24 is tilted downward, the other end of the rocker plate 24 lifts the limiting plate 25 upward. The inner top of the tank body 1 is connected to a plurality of circumferentially distributed protrusions 5. When the rocker plate 24 rotates with the hollow shaft 2, the plurality of protrusions 5 will take turns pressing the tilted end of the rocker plate 24.

[0042] During the stirring process of the vertical pipe 6 revolving around the hollow shaft 2 with the slide table 13, the slide table 13 will drive the rocker plate 24 to revolve together. The raised end of the rocker plate 24 always moves in a circular motion against the inner top of the tank body 1. When the rocker plate 24 moves to the position corresponding to the protrusion 5 on the inner wall, its raised end is subjected to the downward pressing action of the protrusion 5, causing the other end of the rocker plate 24 to tilt upward, thereby pushing the limiting plate 25 to rise upward. The limiting plate 25 drives the vertical pipe 6 to move upward. This lifting and lowering motion increases the vertical air intake range of the air inlet 7, and also causes the head 10 to generate a shearing force in the raw material that helps to crush the material.

[0043] When the rocker arm 24 passes the current protrusion 5, the vertical pipe 6 moves downward to return to its original position under the reset action of the spring 14. Thus, the multiple protrusions 5 arranged circumferentially on the inner wall of the tank 1 enable the vertical pipe 6 to reciprocate up and down on the slide table 13. This periodic up and down not only further expands the overall working area of ​​the air inlet 7, but also intermittently reduces the raw material resistance encountered by the vertical pipe 6 during revolution, making the operation smoother and more efficient.

[0044] Reference Figure 6 As shown, a piston column 26 is fixedly connected to the upper part of the L-shaped frame 22. The outer wall of the piston column 26 is provided with a sealing ring that matches the inner wall of the vertical pipe 6. The lower end of the piston column 26 is sleeved in the upper port of the vertical pipe 6. When the vertical pipe 6 moves upward, the piston column 26 is pushed towards the inner bottom of the vertical pipe 6 and blocks the port of the exhaust pipe 12.

[0045] When the vertical pipe 6 is raised, the piston rod 26 is inserted into the vertical pipe 6 and blocks the port of the exhaust pipe 12. This creates a closed space inside the vertical pipe 6, and the air pressure increases accordingly. The pressurized gas is discharged outward through the air inlet 7, thereby realizing the function of automatically clearing the air inlet 7 by utilizing the internal air pressure, effectively ensuring the continuous unobstructed flow and functionality of the air inlet 7.

[0046] Reference Figure 7 As shown, a plurality of equally spaced baffles 9 are fixedly connected in the groove 8, and the plurality of baffles 9 are respectively located above the air inlet 7.

[0047] When the vertical pipe 6 moves upward, the baffle 9 fixed on the vertical pipe 6 rises along with it. During the upward movement, the baffle 9 blocks and pushes away the organic fertilizer material located above the air inlet 7, thereby forming a relatively obvious hollow area below the baffle 9. This hollow area reduces the pressure and adhesion of the material to the air inlet 7, providing more favorable space conditions for high-pressure gas to be discharged from the air inlet 7, blowing away and clearing the blocked material, thus enhancing the automatic clearing effect.

[0048] Reference Figure 4 and Figure 8As shown, the hollow shaft 2 has an inner hole 17 in its inner wall and an upper annular gas collecting groove 16 communicating with the inner hole 17 in its inner wall. The output end of the exhaust pipe 12 extends into the upper annular gas collecting groove 16. The lower end of the hollow shaft 2 has a lower annular gas collecting groove 20 communicating with the lower end of the inner hole 17. The outer wall of the hollow shaft 2 is connected to a lower pipe 21 communicating with the lower annular gas collecting groove 20. The top of the hollow shaft 2 is connected to an end cap 18 communicating with the top of the inner hole 17. The outer wall of the end cap 18 is connected to an upper pipe 19 located above the tank body 1. Valves are installed on both the upper pipe 19 and the lower pipe 21.

[0049] When exhausting gas through exhaust pipe 12, the valve on upper pipe 19 is opened, and exhaust gas and steam will first be discharged into upper annular gas collection groove 16, then enter end cover 18 through inner hole 17, and finally be discharged from tank 1 through upper pipe 19.

[0050] Conversely, when it is necessary to reduce heat loss within tank 1, the valve on the lower pipe 21 can be opened. At this time, exhaust gas and steam will enter the lower annular gas collection groove 20 through the inner hole 17, and finally be discharged from tank 1 through the lower pipe 21. During this process, the high-temperature airflow will flow through the inner wall of the hollow shaft 2, and the heat it carries can preheat the air inside the hollow shaft 2, thereby effectively reducing the overall heat loss of the system.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
