Description

Technical Field

[0001] This invention relates to the field of organic fertilizer technology, specifically to a device for producing fast-acting liquid fertilizer from agricultural and livestock organic waste. Background Technology

[0002] Devices for producing fast-acting liquid fertilizer from agricultural and livestock organic waste often use plastic fermentation tanks or seepage-proof fermentation pools that integrate raw material input, closed anaerobic fermentation, simple solid-liquid separation, and biogas slurry static activation. Pre-treated livestock and poultry manure, crop straw, fruit and vegetable residues, and other agricultural and livestock organic waste produced by farmers are added, and the anaerobic degradation is completed in the absence of air to produce biogas for farmers' cooking. After simple filtration and sedimentation separation, the fermentation liquid can be mixed to obtain fast-acting liquid fertilizer, thereby achieving the purpose of applying fast-acting fertilizer to crops.

[0003] Current equipment for producing fast-acting liquid fertilizer from agricultural and livestock organic waste often cannot treat suspended impurities in the fermentation liquid inside the tank. The large amount of impurities in the fermentation liquid can easily clog pipes and valves, requiring the addition of complex external filtration equipment, which is cumbersome. At the same time, as the liquid fertilizer is continuously extracted and the liquid level in the tank continues to drop, the extraction port will be exposed above the liquid surface in advance, and a large amount of liquid fertilizer at the bottom cannot be extracted. The large amount of residual liquid at the bottom of the tank affects the production efficiency of liquid fertilizer. In addition, the extraction port is easily blocked by material residue during the fermentation process, resulting in poor liquid extraction in the later stage.

[0004] To address the above problems, a device for producing fast-acting liquid fertilizer from agricultural and livestock organic waste is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a device for producing fast-acting liquid fertilizer from agricultural and livestock organic waste. By using this device, the problems mentioned above can be solved, such as the inability to effectively treat suspended solid impurities in the tank, the easy blockage of pipelines by impurities in the fermentation liquid, the need to add complex external filtration equipment, and the large amount of liquid fertilizer residue in the tank after fermentation and the low utilization rate of raw materials.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for producing fast-acting liquid fertilizer from agricultural and livestock organic waste, comprising a fermentation tank and an exhaust pipe connected above the fermentation tank, an exhaust pipe connected to one side of the exhaust pipe, an exhaust pipe connected to one side of the fermentation tank, a gas storage tank connected to one side of the fermentation tank, a liquid passage pipe connected to one side of the fermentation tank, a control valve installed in the middle of the liquid passage pipe, and an exhaust pipe connected to a liquid storage tank. The storage tank is connected to a mixing tank on the side away from the fermentation tank. The front end of the mixing tank is connected to a drip irrigation pipe. The storage tank and the mixing tank are connected by a servo pump. The fermentation tank is equipped with a liquid extraction mechanism. The stirring mechanism and the liquid extraction mechanism are connected through each other, and the stirring mechanism can rotate at the center of the liquid extraction mechanism.

[0007] Furthermore, the stirring mechanism includes a geared motor installed on the top of the fermentation tank, and the output end of the geared motor is rotatably connected to a rotating shaft. A limit slider is fixed on one side of the rotating shaft, and a lifting shaft is sleeved on the lower outer side of the rotating shaft. Several stirring blades are fixed on the outer circumference of the lifting shaft.

[0008] Furthermore, the liquid taking mechanism includes a mounting sleeve rotatably mounted on a lifting shaft, and mounting bases are fixed on both sides of the mounting sleeve. Limiting rails are provided on both sides of the mounting base, and the limiting rails are fixed to the inner surface of the fermenter. A limiting block is fixed on one side surface of the mounting base. An active cavity is opened inside the mounting sleeve, and a fixing ring is provided above the inside of the active cavity, and the fixing ring is fixed to the lifting shaft.

[0009] Furthermore, a second mounting sleeve is provided above the first mounting sleeve. The second mounting sleeve is rotatably connected to the lifting shaft, and a mounting top frame is fixed on both sides of the second mounting sleeve. A cover plate is installed on the upper surface of the mounting base. Several sets of connecting frames are provided between the mounting top frame and the mounting base. The connecting frames and the cover plate are rotatably connected to the lifting shaft. A limit plate is fixed on one side of the surface of the connecting frame. A filter screen is fixedly connected between the mounting top frame and the connecting frame, between two connecting frames, and between the connecting frame and the cover plate. A protruding plate is fixed on one side of the upper surface of the mounting top frame.

[0010] Furthermore, a rotating screw is rotatably mounted in the middle of the lifting shaft, and a driven gear is externally threaded onto the upper part of the rotating screw. A driving gear is meshed with one side of the driven gear, and a baffle plate is provided on one side of the mounting base.

[0011] Furthermore, the mounting base includes a liquid guide pipe connected to the liquid passage pipe, and the input end of the liquid guide pipe is connected to a liquid inlet, and several sets of liquid inlets are provided on the mounting base.

[0012] Furthermore, a limiting groove is formed on one end surface of the mounting base, and the cover plate can slide within the limiting groove.

[0013] Furthermore, a sliding frame is slidably mounted on the surface of the mounting base, and a sliding column is fixed on one side of the sliding frame, and a support spring is fixed on one side of the sliding column. The sliding column is elastically connected to the mounting base through the support spring.

[0014] Furthermore, one end of the sliding frame is fixed with an inclined head, and several extrusion rods are fixed vertically on the inner surface of the fermenter.

[0015] Furthermore, several sets of brush holders are fixed in the middle of the sliding frame, and the number of brush holders matches the number of liquid inlets. Several sets of triangular blocks are fixed at the bottom of the sliding frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention features a liquid collection mechanism consisting of a built-in folding fan-shaped expandable filter screen. During the fermentation stage, the filter screen is retracted without interfering with anaerobic fermentation and material stirring. After fermentation, it can be expanded to form a fully covered circular filter surface. As the entire mechanism slowly moves downward, it continuously intercepts and settles residual solid impurities, greatly improving the solid-liquid separation efficiency in the tank. The resulting liquid fertilizer has a higher purity, preventing impurities from clogging the liquid pipe and control valve from the source, eliminating the need for complex external filtration equipment, and simplifying the entire fertilizer production process.

[0017] 2. The present invention features a liquid inlet structure that moves synchronously with the liquid level, combined with an openable and closable cover. During fermentation, the cover closes the liquid inlet to prevent material residue from clogging the liquid absorption part. When extracting the fertilizer liquid, the cover opens, and the liquid absorption port automatically adapts to the liquid level as the liquid level drops. This maximizes the extraction of fermentation liquid from the tank, significantly reduces liquid fertilizer residue, reduces the loss of agricultural and livestock organic waste raw materials, and effectively improves the overall yield of liquid fertilizer.

[0018] 3. During the downward movement of the liquid collection mechanism of this invention, the squeezing rod, in conjunction with the spring, drives the sliding frame to reciprocate. The brush frame continuously cleans the liquid inlet to prevent micropore blockage. The bottom triangular block simultaneously pushes the bottom fermented mud to form a liquid collection pit, collecting the residual fertilizer liquid at the bottom for easy extraction. The entire set of stirring, spreading, filtering, blockage clearing, and liquid collection actions are integrated and linked, requiring minimal manual intervention. It combines the dual advantages of filtration and anti-blockage and residual liquid recovery, improving the continuous and stable operation capability of the equipment. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] To address the technical challenge of requiring complex external filtration equipment due to the high level of impurities in the fermentation broth that easily clogs pipes when treating suspended solids inside the tank, the following preferred technical solution is provided: like Figures 1-9 As shown, a device for producing fast-acting liquid fertilizer from agricultural and livestock organic waste includes a fermentation tank 1 and an exhaust pipe 10 connected above the fermentation tank 1. The fermentation tank 1 is a conventional sealed anaerobic fermentation device. Pre-treated agricultural and livestock organic waste and water can be added into the fermentation tank 1 for anaerobic fermentation. The exhaust pipe 10 can vent the biogas produced during fermentation. After anaerobic fermentation for a period of time, the fermentation tank 1 can produce fast-acting fertilizer juice that can be applied to crops. One side of the exhaust pipe 10 is connected to a gas storage tank 2. The exhaust pipe 10 can pass the biogas produced into the conventional gas storage tank 2 for collection, thereby realizing multiple uses of agricultural and livestock organic waste after fermentation. A stirring mechanism 3 is installed on the top of the fermentation tank 1. The stirring mechanism 3 uses a servo motor to stir the inside of the fermentation tank 1, which helps to ensure the fermentation effect of the agricultural and livestock organic waste in the tank. After fermentation for a period of time, the stirring mechanism 3 is stopped by the existing principle controller outside the tank. Then, the liquid fertilizer juice produced by fermentation in the fermentation tank 1 can be separated by the natural sedimentation of the material. The existing principle controller is not shown in the figure. A liquid passage pipe 4 is connected to one side of the fermentation tank 1, and a control valve 6 is installed in the middle of the liquid passage pipe 4. The output end of the liquid passage pipe 4 is connected to a storage tank 7. The storage tank 7 is connected to the liquid passage pipe 4 by an internal suction pump. When the controller opens the control valve 6 after fermentation in the fermentation tank 1, the liquid fertilizer juice produced by fermentation can be passed into the storage tank 7 for collection through the liquid passage pipe 4. The storage tank 7 is connected to a mixing tank 8 on the side away from the fermentation tank 1. The front end of the mixing tank 8 is connected to a drip irrigation pipe 9. The storage tank 7 and the mixing tank 8 are connected by a servo pump 20 based on existing principles. The opening and closing of the servo pump 20 is controlled by a controller. Water can be added to the mixing tank 8 from the outside. The liquid fertilizer stored in the storage tank 7 can be pumped into the mixing tank 8 and mixed and diluted with water. Then, it can be transported to the drip irrigation system of the planting area through the drip irrigation pipe 9 for irrigation, thereby achieving the purpose of applying fast-acting fertilizer to crops. The fermenter 1 is equipped with a liquid collection mechanism 5, and the stirring mechanism 3 is connected to the liquid collection mechanism 5. The stirring mechanism 3 can rotate in the center of the liquid collection mechanism 5. The liquid collection mechanism 5 is a fan-shaped, expandable filter structure. During normal fermentation, the liquid collection mechanism 5 is closed together, which does not hinder the stirring of materials, oxygen supply and microbial fermentation reaction. After fermentation, the liquid collection mechanism 5 can be fully expanded in conjunction with the stirring mechanism 3 to form a fully covered circular filter surface. At the same time, after the liquid collection mechanism 5 is expanded, it can move slowly down in the tank in conjunction with the stirring mechanism 3. During the downward movement of the liquid collection mechanism 5, it intercepts the residue and solid fermentation impurities in the fermentation liquid. The solid impurities in the fermentation liquid can be continuously blocked and settled downward, thereby improving the efficiency of liquid fertilizer separation after fermentation in the fermenter 1. This avoids the problem of directly releasing liquid fertilizer with a high impurity content, which can easily cause blockage of the liquid pipe 4 and control valve 6. It can also reduce the use of external complex filtration equipment. Furthermore, the liquid-absorbing part of the liquid-collecting mechanism 5 is connected to the liquid-passing pipe 4. During normal fermentation, the liquid-collecting mechanism 5 is closed, and the liquid-absorbing part of the liquid-collecting mechanism 5 is always in a closed state. This prevents the residue from contaminating and clogging the liquid-absorbing part of the liquid-collecting mechanism 5 during normal fermentation of agricultural and livestock organic waste. This makes the subsequent flow of liquid fertilizer juice smoother and avoids impurities clogging the filter screen and contaminating the valve in advance during fermentation, which would be difficult to clean in a timely and effective manner and thus affect the flow of liquid fertilizer. At the same time, when the liquid-collecting mechanism 5 moves down to block and settle solid impurities in the fermentation liquid, it can also continuously adjust the position of the liquid-absorbing part of the liquid-collecting mechanism 5 downward. As the liquid level continues to drop after the liquid fertilizer is extracted from the tank, the downward-moving liquid-absorbing part can automatically adapt to the change in liquid level, ensuring the effectiveness of liquid fertilizer extraction, reducing the residue of liquid fertilizer in the tank, increasing the liquid fertilizer yield, and reducing raw material fermentation loss.

[0023] The stirring mechanism 3 includes a geared motor 31 installed on the top of the fermentation tank 1, and the output end of the geared motor 31 is rotatably connected to a rotating shaft 32. The geared motor 31, which is controlled by a controller, can drive the rotating shaft 32 to rotate inside the fermentation tank 1 by means of a gearbox. A limit slider 33 is fixed on one side of the rotating shaft 32, and a lifting shaft 34 is sleeved on the lower outer side of the rotating shaft 32. Several stirring blades 35 are fixed on the outer circumference of the lifting shaft 34. When the rotating shaft 32 rotates, the limit slider 33 can synchronously drive the lifting shaft 34 and the stirring blades 35 to rotate, which helps to ensure the fermentation effect of agricultural and livestock organic waste in the fermentation tank 1.

[0024] like Figures 3-7 As shown, the liquid taking mechanism 5 includes a mounting sleeve 51 rotatably mounted on the lifting shaft 34, and mounting bases 52 are fixed on both sides of the mounting sleeve 51. Limiting rails 30 are provided on both sides of the mounting bases 52, and the limiting rails 30 are fixed to the inner surface of the fermentation tank 1, which can restrict the position of the mounting bases 52, so that the mounting bases 52 can only move up and down along the limiting rails 30, and will not rotate with the lifting shaft 34. A limiting block 59 is fixed on one side surface of the mounting bases 52. The limiting block 59 can elastically extend and retract on the mounting bases 52. Under normal fermentation conditions, the limiting block 59 can support the mounting bases 52 and the components on them on the limiting rails 30, preventing the mounting bases 52 from moving down randomly during normal fermentation.

[0025] The installation sleeve 51 has an internal movable cavity 512, and a fixing ring 511 is provided at the top of the movable cavity 512. The fixing ring 511 is fixed on the lifting shaft 34. During normal fermentation, the fixing ring 511 is at the top of the movable cavity 512.

[0026] Mounting sleeve 2 53 is provided above mounting sleeve 1 51. Mounting sleeve 2 53 is rotatably connected to lifting shaft 34, and mounting top frame 54 is fixed on both sides of mounting sleeve 2 53. Cover plate 58 is installed on the upper surface of mounting base 52. Several sets of connecting frames 55 are provided between mounting top frame 54 and mounting base 52. Both connecting frames 55 and cover plate 58 are rotatably connected to lifting shaft 34. Limiting plate 56 is fixed on one side of the surface of connecting frame 55. Limiting plate 56 can restrict the rotation and opening direction of mounting top frame 54 and connecting frame 55, so that mounting top frame 54 and connecting frame 55 can only be opened by rotating counterclockwise along lifting shaft 34. At the same time, when storing, it can also ensure that mounting top frame 54 and connecting frame 55 are folded together and will not exceed their original position.

[0027] A barrier filter 57 is fixedly connected between the top mounting frame 54 and the connecting frame 55, between the two connecting frames 55, and between the connecting frame 55 and the cover plate 58. The top mounting frame 54, connecting frame 55, cover plate 58, and base mounting frame 52 form a structure similar to the ribs of a folding fan, while the barrier filter 57 in the middle forms the fan surface. Figure 4 and Figure 5 As shown, during normal fermentation, the fan ribs and fan surface are gathered together, which does not hinder the mixing of materials, oxygen supply and microbial fermentation reaction. A protruding plate 510 is fixed on one side of the upper surface of the mounting frame 54.

[0028] A rotating screw 36 is rotatably mounted in the middle of the lifting shaft 34, and a driven gear 37 is externally threaded onto the upper part of the rotating screw 36. A driving gear 38 is meshed with one side of the driven gear 37. The driving gear 38 is driven by the top servo motor and controlled by the controller, which can drive the driven gear 37 to rotate. This allows the driven gear 37 to move up and down with the rotating screw 36 through the threaded engagement between the driven gear 37 and the rotating screw 36. Thus, the rotating screw 36 can also drive the lifting shaft 34 to move up and down together with the stirring blade 35 along the rotating shaft 32 under the restriction of the limiting slider 33.

[0029] After mixing, one set of mixing blades 35 is positioned parallel above the mounting frame 54. After fermentation, the lifting shaft 34 and mixing blades 35 are moved downwards, causing the mixing blades 35 to adhere to the upper surface of the mounting frame 54. The fixing ring 511 also moves to the bottom of the movable cavity 512. At this time, the reduction motor 31 slowly drives the mixing blades 35 to rotate 180 degrees counterclockwise. The mixing blades 35 then use the convex plate 510 to drive the mounting frame 54 to rotate counterclockwise, thus unfolding the opening barrier filter 57. Figure 7 and Figure 9As shown, when the stirring blade 35 rotates 180 degrees, the mounting top frame 54, connecting frame 55, and barrier filter 57 of the left and right sets of fan ribs and fan surface structures will be fully opened, while the mounting base frames 52 on both sides remain stationary. This allows the mounting top frame 54 to rotate 180 degrees and be positioned just above the other set of mounting base frames 52, thereby forming a circular filter screen. At the same time, when storing the filter screen, the stirring blade 35 rotates clockwise, which pushes the mounting top frame 54, connecting frame 55, and barrier filter 57 to fold and retract.

[0030] A baffle plate 50 is provided on one side of the mounting base 52. The baffle plate 50 can seal the gap between the mounting base 52 and the barrier filter screen 57 after it is unfolded, so that the liquid suction part on the mounting base 52 can be above the filter surface of the barrier filter screen 57, ensuring that the subsequent extraction is filtered liquid fertilizer. At the same time, the gaps on the side of the baffle plate 50 and other parts are small, and their impact on the overall filtration of the barrier filter screen 57 is negligible. After the filter screen is unfolded into a circular surface, the lifting shaft 34 and the stirring blade 35 continue to move downward. At this time, the mounting top frame 54 and the mounting base 52 are respectively above the stirring blade 35. The fixed ring 511 pushes the overall circular filter screen downward, allowing the liquid taking mechanism 5 to simultaneously intercept residues and solid fermentation impurities in the fermentation liquid during the downward movement. This allows solid impurities in the fermentation liquid to be continuously blocked and settled downward, thereby improving the efficiency of solid sedimentation and liquid fertilizer separation after fermentation in the fermentation tank 1. This helps to shorten the liquid fertilizer acquisition time. At the same time, the liquid fertilizer obtained from the upper layer after overall blocking and sedimentation has a higher purity, avoiding the direct discharge of liquid fertilizer with a high impurity content, which can easily cause blockage of the liquid pipe 4 and control valve 6. It also reduces the use of external complex filtration equipment.

[0031] To address the technical challenges of high residual liquid fertilizer content and low raw material utilization after fermentation, the following preferred technical solutions are provided: like Figures 1-11 As shown, the mounting base 52 includes a liquid guide pipe 521 connected to the liquid pipe 4. The liquid guide pipe 521 is a flexible and corrosion-resistant hose that can adapt to the lifting and lowering of the mounting base 52. The input end of the liquid guide pipe 521 is connected to a liquid inlet 522, and several sets of liquid inlets 522 are provided on the mounting base 52. The mounting base 52 has a hollow structure. Using the liquid inlet 522 and the liquid guide pipe 521, the liquid fertilizer filtered by the above-mentioned barrier filter 57 can be circulated and finally drawn into the storage tank 7 for collection. At the same time, a fine-pore filter screen is fixed on the liquid inlet 522, which can perform secondary filtration on the incoming liquid fertilizer, thereby ensuring the cleanliness of the finally collected liquid fertilizer and reducing the use of external complex filtration equipment.

[0032] A limiting groove 60 is formed on one end surface of the mounting base 52, and the cover plate 58 can slide within the limiting groove 60. Figure 8 As shown above, when the filter screen 57 is fully extended, the cover plate 58 will open off the mounting base 52 in a staggered manner, but will not completely leave the surface of the mounting base 52. At this time, the liquid inlet 522 on the surface of the mounting base 52 will be exposed, so that the filter screen 57 will only expose the liquid inlet 522 when it is fully extended. When the cover plate 58 is closed during normal fermentation, the liquid inlet 522 is always in a closed state, which can prevent the material residue from contaminating and clogging the exposed liquid inlet 522 in advance during fermentation, thus making the liquid fertilizer flow more smoothly. At the same time, the liquid inlet 522, which moves down with the mounting base 52, can automatically adapt to changes in liquid level, ensuring the effect of liquid fertilizer extraction, reducing the residue of liquid fertilizer in the tank, increasing the liquid fertilizer yield, and reducing raw material fermentation loss.

[0033] To address the technical problem of the condensate inlet being prematurely blocked by residue during fermentation and resulting in poor condensate extraction in the later stages, the following preferred technical solution is provided: like Figures 2-11 As shown, a sliding frame 523 is slidably mounted on the surface of the mounting base 52, and a sliding column 524 is fixed on one side of the sliding frame 523. A support spring 525 is fixed on one side of the sliding column 524, and the sliding column 524 is elastically connected to the mounting base 52 through the support spring 525. The sliding column 524 and the mounting base 52 slide in a sealed manner, so that the support spring 525 will not come into contact with the fermentation material.

[0034] One end of the sliding frame 523 is fixed with an inclined head 526. Several extrusion rods 40 are fixed vertically on the inner surface of the fermentation tank 1. Both the extrusion rods 40 and the inclined head 526 are made of wear-resistant material. During normal fermentation, the mounting base 52 is located above the extrusion rods 40. As described above, when the filter screen 57 is fully extended and slowly moves downward, the extrusion rods 40 will continuously and slowly extrude through the inclined head 526, causing the sliding frame 523 to move left and right along the surface of the mounting base 52 under the action of the support spring 525.

[0035] Several sets of brush holders 527 are fixed in the middle of the sliding frame 523, and the number of brush holders 527 matches the number of liquid inlets 522. The bottom brush surface of the brush holder 527 is attached to the surface of the mounting base 52. When the sliding frame 523 moves left and right, it will synchronously drive the brush holders 527 to move back and forth from the surface of the liquid inlet 522. This will create a continuous brushing effect on the surface of the liquid inlet 522 when the mounting base 522 moves down, thereby further preventing the possibility of liquid fertilizer clogging the liquid inlet 522 and ensuring smooth liquid inflow into the liquid inlet 522. The bottom of the sliding frame 523 is fixed. There are several sets of triangular blocks 528, which can also move left and right synchronously with the sliding frame 523. When the triangular blocks 528 come into contact with the settled fermented mud, they can push and squeeze the fermented mud, so that the fermented mud at the bottom of the mounting base 52 can be pushed out into a pit, allowing the fermented liquid that has not been absorbed from the surface of the fermented mud to flow into the pit. Then the mounting base 52 slowly moves down into the pit, and the liquid inlet 522 is used to suck away the fermented liquid that has flowed into the pit, thereby maximizing the extraction of fermented liquid, reducing the residue of liquid fertilizer in the tank, and improving the yield of liquid fertilizer.
