[0005] In order to overcome the shortcomings of the existing technology, the present invention provides a fermentation equipment for producing biological organic fertilizer. In the existing technology, waste feces fermentation adopts a traditional extrusion method, which cannot efficiently dehydrate the feces waste, and the dehydrated wastewater cannot be recycled. The fermentation reaction stirring adopts a traditional motor-driven stirring method, which has low working efficiency and poor stirring effect. Dehydration, stirring and fermentation are carried out separately, which affects the fermentation efficiency.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A fermentation device for producing bio-organic fertilizer, comprising:

[0008] The feces dehydration cylinder has a feeding port arranged obliquely on the outside of the feces dehydration cylinder, a spiral extrusion mechanism arranged inside the feces dehydration cylinder, and three supporting legs arranged obliquely on the bottom of the feces dehydration cylinder, and silicone heads are arranged at the bottom of the three supporting legs;

[0010] The electromagnetic stirring mechanism is connected to the bottom end of the electric field sterilization mechanism;

[0011] The waste liquid recovery mechanism is located below the feces dehydration cylinder and is connected to the electromagnetic stirring mechanism.

[0012] Preferably, the spiral extrusion mechanism includes a servo motor, which is installed on the top of the feces dehydration cylinder. A rotating shaft is installed on the output shaft of the servo motor. The rotating shaft is vertically rotated and installed on the feces dehydration cylinder through a bearing. A feeding spiral blade and a compression spiral blade are welded and installed on the outer side of the rotating shaft from top to bottom. A plurality of dehydration holes are opened on the feeding spiral blade and the compression spiral blade. The pitch of the feeding spiral blade is 300 mm and the length is 120 cm. The pitch of the compression spiral blade is gradually reduced to 150 mm and the length is reduced to 80 cm.

[0013] The servo motor drives the rotating shaft to rotate, and the rotating shaft drives the feeding spiral blade and the compression spiral blade to rotate. The feces are first transported by the compression spiral blade. When it moves to the position of the feeding spiral blade, the pitch is shortened to compress the feces. The compressed feces are discharged through the curved guide tube. The dehydration hole is set for water leakage. The wastewater flows into the collection tank through the waste liquid collection pipe. A segmented spiral blade design is adopted (the pitch of the feeding spiral blade is 300mm, and the pitch of the compression spiral blade decreases to 150mm). Combined with the pressure gradient increased to 2MPa / m, the feces are compressed and dehydrated step by step.

[0014] Preferably, the electric field sterilization mechanism includes two fixed plates, which are symmetrically welded to the outside of the feces dehydration cylinder. A negative electrode plate and a positive electrode plate are installed on the inner sides of the two fixed plates respectively. The top side of the feces dehydration cylinder is connected to a curved material guide pipe, which is located between the negative electrode plate and the positive electrode plate.

[0015] An electric field is formed between the negative plate and the positive plate through power supply, thereby achieving the purpose of efficient sterilization.

[0016] Preferably, the electromagnetic stirring mechanism includes a hexagonal column, three oblique support legs are fixedly installed on the bottom of the hexagonal column, electromagnetic plates are installed on the six outer sides of the hexagonal column, and the six electromagnetic plates are combined into a honeycomb hexagonal structure. A heating coil is embedded in the bottom of the hexagonal column, and a stirring tank is provided at the top of the hexagonal column. The inner wall of the stirring tank is provided with an arc surface to facilitate the discharge of feces. The bottom of the hexagonal column is connected to a discharge pipe, and a discharge solenoid valve is installed on the discharge pipe.

[0017] Preferably, a top cover is installed on the top of the hexagonal column, the top center position of the top cover is connected to the bottom of the curved material guide tube, a sealing ring is fixedly installed on the bottom of the top cover, the sealing ring is sealed with the inner wall of the stirring tank, a thermostat is installed on the top of the top cover, the sensor head of the thermostat is located below the top cover, a fermentation inlet is provided on the top of the top cover, six screw grooves are opened on the top of the hexagonal column, six bolt rods are installed on the top cover, and the bolt rods are adapted to the screw grooves.

[0018] Preferably, the waste liquid recovery mechanism includes a collection tank, which is located below the feces dehydration cylinder. The bottom of the feces dehydration cylinder is connected to a waste liquid collection pipe, which is connected to the collection tank. A filtering unit is provided in the collection tank. A transverse support plate is fixedly installed on the top of the collection tank, and a water supply pump is installed on the top of the transverse support plate. The inlet of the water supply pump is connected to a water suction pipe, which extends to the interior of the feces dehydration cylinder. The outlet of the water supply pump is connected to a water supply pipe, which is installed on the outside of the hexagonal column and is connected to the interior of the stirring tank.

[0019] Preferably, the filtration unit comprises a filtration frame, which is installed inside the collection tank, and a stainless steel filter screen, an activated carbon filter screen and an ultrafiltration membrane are fixedly installed in the filtration frame in sequence.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] First, the segmented spiral blade design (the pitch of the feed spiral blade is 300mm, and the pitch of the compression spiral blade decreases to 150mm) achieves step-by-step compression and dehydration of feces, achieving good dehydration effect. The spiral blades have dehydration holes to balance drainage efficiency and anti-clogging.

[0022] Second, piezoelectric field dynamic sterilization technology forms a non-contact high-voltage electric field (inside the curved material guide tube) through positive and negative plates, replacing traditional high-temperature or chemical sterilization. The sterilization is environmentally friendly and has no chemical residues. The sterilization process temperature is ≤50°C, avoiding thermal decomposition and loss of organic matter.

[0023] Third, the three-dimensional electromagnetic stirring fermentation technology uses a honeycomb hexagonal electromagnetic plate to drive the ferroferric oxide particles to form a three-dimensional spiral stirring field. The electromagnetic field frequency is adjustable (50-200Hz), and the particle movement speed reaches 2m / s, improving stirring uniformity by 40% compared to mechanical stirring. It is contactless and wear-free.

[0024] Fourth, the three-stage filtration (stainless steel mesh + activated carbon + ultrafiltration membrane) is linked with the water supply pump to realize the resource utilization of wastewater.

[0025] In summary, the present invention achieves technological breakthroughs in dehydration, sterilization, stirring, waste liquid recycling and other links through mechatronic design, and is highly efficient, environmentally friendly and economical, and is suitable for large-scale organic fertilizer production.

[0040] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific examples, but the following examples are only preferred embodiments of the present invention, not all. Based on the examples in the embodiments, other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention. The experimental methods in the following examples, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following examples, unless otherwise specified, can be obtained from commercial channels.

[0041] Example 1

[0042] like Figures 1-10 As shown, the present invention provides a fermentation equipment for producing biological organic fertilizer, including a feces dehydration cylinder 1, an electric field sterilization mechanism 2 and an electromagnetic stirring mechanism 4. A feeding port 12 is obliquely provided on the outer side of the feces dehydration cylinder 1, a spiral extrusion mechanism 11 is provided inside the feces dehydration cylinder 1, and three supporting legs 13 are obliquely provided at the bottom of the feces dehydration cylinder 1. The bottoms of the three supporting legs 13 are all provided with silicone heads. The electric field sterilization mechanism 2 is connected to the top side of the feces dehydration cylinder 1, and the electromagnetic stirring mechanism 4 is connected to the bottom end of the electric field sterilization mechanism 2.

[0043] like Figure 8 、 Figure 9 As shown, in this embodiment, the spiral extrusion mechanism 11 includes a servo motor 111, which is installed on the top of the feces dehydration cylinder 1. A rotating shaft 112 is installed on the output shaft of the servo motor 111. The rotating shaft 112 is installed on the feces dehydration cylinder 1 for vertical rotation through a bearing. A feeding spiral blade 113 and a compression spiral blade 114 are welded on the outer side of the rotating shaft 112 from top to bottom. A plurality of dehydration holes 115 are provided on the feeding spiral blade 113 and the compression spiral blade 114. The pitch of the feeding spiral blade 113 is 300 mm and the length is 120 cm. The pitch of the compression spiral blade 114 is reduced to 150 mm and the length is reduced to 80 cm.

[0044] The servo motor 111 drives the rotating shaft 112 to rotate, and the rotating shaft 112 drives the feeding spiral blade 113 and the compression spiral blade 114 to rotate.

[0047] like Figure 1-Figure 5 As shown, in this embodiment, the electric field sterilization mechanism 2 includes two fixed plates 21, which are symmetrically welded to the outside of the feces dehydration cylinder 1. A negative electrode plate 23 and a positive electrode plate 24 are respectively installed on the inner sides of the two fixed plates 21. The top side of the feces dehydration cylinder 1 is connected to a curved material guide tube 22, which is located between the negative electrode plate 23 and the positive electrode plate 24. An electric field is formed between the negative electrode plate 23 and the positive electrode plate 24 when power is supplied to the positive electrode plate 24, thereby achieving the purpose of efficient sterilization.

[0048] Specifically, the main frequency is 2450MHz±50MHz (penetration depth 20-27cm) + auxiliary frequency is 915MHz (penetration depth 50-60cm);

[0049] Sterilization rate: The electric field strength is designed to be 15kV / cm, and the sterilization rate is ≥99.9% (pathogens such as Escherichia coli and Salmonella).

[0050] Energy consumption comparison: sterilization energy consumption is only 0.5kW·h / m 3 , compared with steam sterilization (2.5kW·h / m 3 )Save 80%.

[0051] Environmental protection: No chemical residue, sterilization process temperature ≤ 50℃, avoiding thermal decomposition loss of organic matter.

[0052] like Figure 6 、 Figure 7As shown, in this embodiment, the electromagnetic stirring mechanism 4 includes a hexagonal column 42, three oblique support legs 43 are fixedly installed at the bottom of the hexagonal column 42, and electromagnetic plates 41 are installed on the six outer sides of the hexagonal column 42. The six electromagnetic plates 41 are combined into a honeycomb hexagonal structure, and a heating coil 49 is embedded in the bottom of the hexagonal column 42. A stirring tank 45 is opened on the top of the hexagonal column 42, and the inner wall of the stirring tank 45 is provided with an arc surface 451 to facilitate the discharge of feces. The bottom of the hexagonal column 42 is connected to a discharge pipe 410, and a discharge electromagnetic valve 411 is installed on the discharge pipe 410. A top cover 44 is installed on the top of 42, and the top center position of the top cover 44 is connected to the bottom of the curved material guide tube 22. A sealing ring 441 is fixedly installed on the bottom of the top cover 44, and the sealing ring 441 is sealed with the inner wall of the stirring tank 45. A thermostat 48 is installed on the top of the top cover 44, and the sensor head of the thermostat 48 is located below the top cover 44. A fermentation input port 442 is provided on the top of the top cover 44. Six screw grooves 46 are opened on the top of the hexagonal column 42, and six bolt rods 47 are installed on the top cover 44, and the bolt rods 47 are adapted to the screw grooves 46.

[0053] Specifically, before use, ferroferric oxide particles are added into the stirring tank 45. The ferroferric oxide particles have a particle size of 10 nm ± 2 nm and are coated with polyethyleneimine (PEI) coating to prevent agglomeration.

[0054] Electromagnetic Matrix Design:

[0055] Magnetic pole array: six electromagnetic plates 41 combined in a hexagonal honeycomb arrangement, with a single pole power density of 500W / m 2 ;

[0056] Frequency-phase coordinated control: 0.1-100Hz frequency range, adjustable phase difference (0-360°), achieving precise control of three-dimensional eddy current field;

[0057] Lorentz force dominates: electromagnetic field induces internal current of magnetic fluid (current density>1×10 4 A / m 2 ), generating body force (formula: F = J × B) to drive the flow;

[0058] Magnetic viscosity effect: When the magnetic field strength is greater than 0.5T, the magnetic fluid exhibits solid-like properties (viscosity increases 100 times), achieving shear crushing function;

[0059] By directly acting on the magnetic fluid with an electromagnetic field, traditional mechanical transmission losses are avoided (energy conversion efficiency > 92%). The electromagnetic matrix divides the power supply into sections, forming a local high-intensity magnetic field (gradient > 10T / m) in the reactor.

[0060] Achieve a "magnetic knife" effect to directionally cut fiber clusters (such as straw debris and feces);

[0061] The magnetic fluid forms a spiral upward flow (Reynolds number Re>5000), eliminating the dead corner of fermentation;

[0062] The magnetic fluid movement cuts the magnetic flux lines, and the superconducting coil (Nb3Sn wire, critical magnetic field 12T) recovers the electrical energy. The energy recovery rate is greater than 35%, and the power supply self-sufficiency rate can reach 40%.

[0063] Magnetic fluid circulation cooling: external micro heat pipe (thermal conductivity 4000W / m·K) to remove Joule heat;

[0064] The inner wall of the stirring tank 45 is coated with a diamond-like carbon film (DLC, friction coefficient < 0.05) to prevent material adhesion;

[0065] Self-cleaning mechanism of magnetic fluid: High-frequency magnetic field (>50Hz) induces nanoparticle vibration, peeling off surface deposits.

[0066] Working method: When in use, turn on the power supply and PLC controller, add waste feces into the feces dehydration cylinder 1 through the feeding port 12, the servo motor 111 drives the rotating shaft 112 to rotate, and the rotating shaft 112 drives the feeding spiral blade 113 and the compression spiral blade 114 to rotate. The feces are first conveyed by the compression spiral blade 114. When it moves to the position of the feeding spiral blade 113, the pitch of the spiral blade shortens to compress the feces. The compressed feces is discharged through the curved guide tube 22. The dehydration hole 115 is provided for water leakage;

[0067] By energizing and cooperating with the positive plate 24 and the negative plate 23, a high-voltage electric field is formed between the two, which is used to sterilize the feces inside the curved guide tube 22, with good sterilization effect. The sterilized feces falls into the stirring tank 45. Before use, ferroferric oxide particles are added into the stirring tank 45, and the six electromagnetic plates 41 are energized to generate an electromagnetic field, so that a three-dimensional spiral electromagnetic field is formed inside the stirring tank 45. Multiple ferroferric oxide particles move at high speed along with the three-dimensional spiral electromagnetic field to stir the feces, and the contactless stirring improves the stirring effect. Fermentation bacteria are added into the stirring tank 45 through the fermentation inlet 442 for fermentation. The stirring time and interval time are set. After the fermentation is completed, the sealing ring 441 is opened, and the fermented organic fertilizer is discharged through the discharge pipe 410.

Figure 3 、 Figure 4 As shown, in order to better realize the present invention, the following setting is particularly adopted: in this embodiment, a waste liquid recovery mechanism 3 is further provided below the feces dehydration cylinder 1, and the waste liquid recovery mechanism 3 is connected to the electromagnetic stirring mechanism 4.

[0070] like Figure 1-Figure 4 As shown, in this embodiment, the waste liquid recovery mechanism 3 includes a collection tank 31, which is located below the feces dehydration cylinder 1. The bottom of the feces dehydration cylinder 1 is connected to a waste liquid collection pipe 38, which is connected to the collection tank 31. A filter unit 33 is provided in the collection tank 31. A transverse support plate 32 is fixedly installed on the top of the collection tank 31, and a water supply pump 35 is installed on the top of the transverse support plate 32. The inlet of the water supply pump 35 is connected to a water suction pipe 34, which extends to the interior of the feces dehydration cylinder 1. The outlet of the water supply pump 35 is connected to a water supply pipe 36, which is installed on the outside of the hexagonal column 42 and connected to the interior of the stirring tank 45. The filter unit 33 includes a filter frame 331, which is installed in the interior of the collection tank 31. A stainless steel filter screen 332, an activated carbon filter screen 333 and an ultrafiltration membrane 334 are fixedly installed in the filter frame 331 in sequence.

[0071] Specifically, wastewater flows into the interior of the collection tank 31 through the waste liquid collection pipe 38. The filter unit 33 is used to filter the wastewater. The stainless steel filter mesh 332 is used for preliminary filtration of the wastewater. The activated carbon filter mesh 333 is used for adsorption filtration of the wastewater. The ultrafiltration membrane 334 is used for fine filtration of the wastewater. The suction pipe 34 is located in the area after the wastewater is filtered. When fermentation and water replenishment are needed, the water replenishment pump 35 works to suck the filtered wastewater through the suction pipe 34 and introduce it into the water replenishment pump 35 through the water supply pipe 36 for water replenishment and fermentation.

[0072] More specifically, the filtration accuracy is: ultrafiltration membrane 334 pore size 0.01 μm, COD removal rate ≥ 90%, SS (suspended solids) ≤ 10 mg / L.

[0073] Water saving rate: the wastewater reuse rate reaches 85%, and the water consumption per ton of organic fertilizer is reduced to 0.3m 3 (Traditional craft 1.2m 3 ).

[0074] Anti-clogging design: The filter frame 331 is detachable, the stainless steel mesh 332 has a pore size of 1mm, the activated carbon layer is 50mm thick, and the dirt holding capacity is increased by 3 times.
