Description

Technical Field

[0001] The invention relates to the technical field of oxygen supply devices for agricultural microbial fertilizer fermentation, in particular to an oxygen supply device for agricultural microbial fertilizer fermentation. Background Art

[0002] The production of agricultural microbial fertilizers (such as rhizobium fertilizers and photosynthetic bacterial fertilizers) relies on the fermentation process of aerobic microorganisms. Aerobic microorganisms continuously consume oxygen during their metabolic processes to decompose organic matter, reproduce, and synthesize metabolites (such as active enzymes and auxins). Insufficient oxygen supply can lead to stagnant microbial growth, prolonged fermentation cycles, and even the production of anaerobic metabolic byproducts (such as organic acids), which can affect fertilizer activity and quality.

[0003] Patent publication number CN218989126U discloses an oxygen supply device for agricultural microbial fertilizer fermentation, comprising a fermentation chamber and an oxygen supply mechanism, the oxygen supply mechanism being movably mounted within the fermentation chamber and comprising an oxygen conduction unit, a transmission unit, and a circulation unit, all of which are disposed within the oxygen supply mechanism.

Agricultural microbial fertilizers are highly dependent on ambient humidity during fermentation, and the humidity of indoor air is far from sufficient to meet the fermentation requirements.

[0014] The present invention provides an oxygen supply device for agricultural microbial fertilizer fermentation. It has the following beneficial effects: 1. The present invention is provided with a humidifying device. A water storage tank is provided inside the oxygen making box. Air is drawn into the connecting pipe through the air extraction device, and the connecting pipe is inserted into the water, so that the air directly enters the water when it is drawn into the oxygen making box, so that the outer wall of the gas molecules wraps the water molecules and disperses from both sides, thereby humidifying the gas in the oxygen making box and avoiding the problem of using a humidifier to directly spray water mist, which easily causes the water mist to enter the oxygen supply pipe and breed bacteria. In combination with the slide rail, the sliding block, the support spring, the return spring, the stop block, the extrusion block, the fixed spring, the return spring and the triangular block, the connecting pipe is completely attached to the oxygen making box after the water storage tank is completely attached to the oxygen making box. It automatically pops up, solving the problem that the internal humidity of the existing oxygen supply device is low during oxygen supply, which is not suitable for bio-fertilizer fermentation; after the water inside the water tank evaporates, the humidity is detected by the humidity sensor, and in conjunction with the cylinder, controller and triangle plate, the water tank is automatically pushed out after the water evaporates, and the connecting pipe is automatically retracted, thereby preventing the staff from being unable to monitor the horizontal surface inside the water tank in real time, resulting in a decrease in humidity after the water evaporates, and at the same time preventing the connecting pipe from being stuck inside the oxygen generator, affecting the removal of the water tank, solving the problem that the horizontal surface inside the water tank is difficult to monitor directly.

[0015] 2. The present invention is provided with a turbulent device. When air is drawn in through the exhaust device, the connecting pipe is cooperated to directly draw air into the water surface. The airflow drives the water flow to generate, drives the turbine to rotate around the fixed rod, disturbs the water surface, and breaks up the bubbles, thereby increasing the contact area between air and water, accelerating the diffusion of water vapor molecules, and solving the problem that after the airflow is directly passed into the water surface, the air is easily overflowed directly through the bubbles, resulting in poor air humidification effect; while humidifying the mixed gas in the oxygen making box, the fixed plate, the motor and the rotating rod are cooperated to drive the fan to rotate, thereby further sending the mixed gas of air and oxygen in the oxygen making box into the oxygen supply pipe, avoiding the situation that only oxygen but no air enters the oxygen supply pipe due to the greater density of oxygen than air, and solving the problem that direct oxygen supply easily leads to a high oxygen concentration inside the oxygen supply pipe, which is not suitable for bio-fertilizer fermentation.

[0016] 3. The present invention is provided with a control device. When the motor is started, the sliding sleeve, the sliding rod and the wave groove drive the sealing plate to slide up and down, so that the sealing plate intermittently closes the connection between the oxygen supply pipe and the oxygen production box, slowing down the rate of transmission of the mixed gas in the oxygen production box to the oxygen supply pipe, and increasing the contact time of oxygen and bio-fertilizer fermentation, thereby improving the utilization rate of oxygen and solving the problem of continuous supply of oxygen leading to reduced utilization rate; while the sealing plate slides up and down, it also drives the sliding plate to slide up and down, and cooperates with the limit plate, the moving block and the limit block to make the knocking block repeatedly knock on the inside of the oxygen production box, so that the oxygen production box drives the water storage tank to vibrate, thereby promoting the broken bubbles to rise from the water surface, improving the efficiency of bubble overflow, and solving the problem of slow rising of bubbles from the water surface, resulting in uneven mixing of oxygen and air.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1-8 One embodiment of the present invention is: an oxygen supply device for agricultural microbial fertilizer fermentation, including an oxygen supply fermentation box 1, an oxygen supply pipe 2 is fixed to the inner wall of the oxygen supply fermentation box 1, an air outlet 3 is opened on the upper surface of the oxygen supply fermentation box 1, an oxygen production box 4 is fixed to the upper surface of the oxygen supply fermentation box 1, the oxygen production box 4 is connected to the oxygen supply pipe 2, a push-pull box 5 passes through the oxygen supply fermentation box 1, and the penetration is slidably connected, a humidifying device for changing the humidity in the air is provided in the oxygen production box 4, and an exhaust device 9 is fixed to the upper surface of the oxygen production box 4, wherein the exhaust device 9 is connected to the oxygen production box 4.

[0021] Among them, the humidifying device includes a water tank 61, a humidity sensor 62, a cylinder 63, a controller 64, a slide rail 65, a sliding block 66, a support spring 67, a connecting pipe 68, a reset spring 69, a stopper 610, an extrusion block 611, a fixed spring 612, a return spring 613, a triangular block 614 and a triangular plate 615. The water tank 61 passes through the side wall of the oxygen production box 4 and is slidably connected at the penetration point. Water is poured into the water tank 61, and sodium peroxide is placed in the water tank 61 to prepare oxygen. The humidity sensor 62 is fixedly connected to the bottom surface of the inner wall of the water tank 61, the cylinder 63 is fixedly connected to the upper surface of the oxygen supply fermentation box 1, and the controller 64 is fixedly connected to the side wall of the cylinder 63. The humidity sensor 62 and the controller 64 are electrically connected. When After the water in the water tank 61 evaporates, the humidity sensor 62 detects that the surrounding humidity has become low and sends an electrical signal to the controller 64. After receiving the electrical signal, the controller 64 controls the cylinder 63 to start, pushing the water tank 61 to slide outward and push the water tank 61 out. The controller 64 is electrically connected to the cylinder 63, the slide rail 65 is fixedly connected to the inner wall of the water tank 61, the sliding block 66 is slidably connected to the inner wall of the slide rail 65, and the support spring 67 is fixedly connected to the bottom surface of the sliding block 66. When the water tank 61 is not pushed into the oxygen generator 4, the support spring 67 is always in a compressed state, and the end of the support spring 67 away from the sliding block 66 is fixedly connected to the bottom surface of the slide rail 65, the connecting pipe 68 is fixedly connected to the side wall of the sliding block 66 away from the slide rail 65, and the return spring 69 is fixed. When the water tank 61 is connected to the side wall of the slide rail 65 and the water tank 61 is not pushed into the oxygen generator 4, the return spring 69 is always in a compressed state, and the stopper 610 is fixedly connected to the end of the return spring 69 away from the slide rail 65. When the extrusion block 611 slides downward, the stopper 610 is no longer pushed by the extrusion block 611, and at the same time, it is subjected to the elastic force of the return spring 69 and slides in the direction away from the slide rail 65, disengaging from the connecting pipe 68. The stopper 610 is slidably connected to the inner wall of the water tank 61. When the connecting pipe 68 is no longer limited by the stopper 610, the support spring 67 is no longer limited, pushing the sliding block 66 to slide upward, driving the connecting pipe 68 to move upward and communicate with the exhaust device 9. The exhaust device 9 draws air in and directly passes it into the water tank 6 through the connecting pipe 68. 1, the drawn air is humidified, the extrusion block 611 is slidably connected to the inner wall of the water storage tank 61, the fixed spring 612 is fixedly connected to the bottom surface of the extrusion block 611, the elastic coefficient of the fixed spring 612 is twice that of the return spring 69, the inclined surface of the extrusion block 611 is slidably connected to the inclined surface of the stopper 610, and the elastic force of the return spring 613 slides downward to the extrusion block 611, pushing the extrusion block 611 to slide downward, squeezing the fixed spring 612, and the return spring 613 is fixedly connected to the upper surface of the inner wall of the water storage tank 61, and the elastic coefficient of the return spring 613 is twice that of the fixed spring 612. The triangular block 614 is fixedly connected to the end of the return spring 613 away from the water storage tank 61, pushing the water storage tank 61 back into the oxygen generator 4,The water tank 61 slides against the inside of the oxygen generator box 4. When the side wall of the water tank 61 slides to the triangular block 614, its side wall slides against the inclined surface of the triangular block 614, pushing the triangular block 614 to slide upward, compressing the return spring 613. When the water tank 61 slides until the side wall fits against the side wall of the oxygen generator box 4, the triangular block 614 is no longer pushed by the side wall of the water tank 61, and at the same time slides downward by the elastic force of the return spring 613, and the triangular plate 615 is fixed. The humidifying device is connected to the upper surface of the inner wall of the water storage tank 61. The water storage tank 61 is set inside the oxygen production box 4. The air is sucked into the connecting pipe 68 through the air extraction device 9. The connecting pipe 68 is inserted into the water. When the air is sucked into the oxygen production box 4, it directly enters the water. The outer walls of the gas molecules wrap around the water molecules and are released from both sides, thereby humidifying the gas in the oxygen production box 4. This avoids the problem of using a humidifier to directly spray water mist, which easily causes the water mist to enter the oxygen supply pipe 2 and breed bacteria. In combination with the slide rail 65, the sliding block 66, the support spring 67, the return spring 69, the stopper 610, the extrusion block 611, the fixing spring 612, the return spring 613 and the triangular block 614, the connecting pipe 68 automatically pops up after the water storage tank 61 is completely attached to the oxygen generator 4, thereby solving the problem that the internal humidity of the existing oxygen supply device is low during oxygen supply, which is not suitable for biofertilizer fermentation. After the water inside the water tank 61 evaporates, the humidity is detected by the humidity sensor 62, and in conjunction with the cylinder 63, the controller 64 and the triangular plate 615, the water tank 61 is automatically pushed out after the water evaporates, and the connecting pipe 68 is automatically retracted. This prevents the staff from being unable to monitor the horizontal surface inside the water tank 61 in real time, resulting in a decrease in humidity after the water evaporates. At the same time, it prevents the connecting pipe 68 from getting stuck inside the oxygen generator box 4, affecting the removal of the water tank 61, and solves the problem that the horizontal surface inside the water tank 61 is difficult to monitor directly.

[0022] When this embodiment is working: water is poured into the water tank 61, and sodium peroxide is placed in the water tank 61, and the water tank 61 is pushed back into the oxygen generator box 4. The water tank 61 slides in contact with the interior of the oxygen generator box 4. When the side wall of the water tank 61 slides to the triangular block 614, its side wall slides with the inclined surface of the triangular block 614, pushing the triangular block 614 to slide upward, compressing the return spring 613. When the water tank 61 slides to the side wall that fits the side wall of the oxygen generator box 4, the triangular block 614 is no longer pushed by the side wall of the water tank 61, and is simultaneously pushed by the return spring The elastic force of 613 slides downward, and when it slides to the extrusion block 611, it pushes the extrusion block 611 to slide downward, squeezing the fixed spring 612. At this time, the stopper 610 is no longer pushed by the extrusion block 611, and is simultaneously affected by the elastic force of the return spring 69, sliding in the direction away from the slide rail 65, breaking away from the connecting pipe 68. The connecting pipe 68 is no longer limited by the stopper 610, and the supporting spring 67 is no longer limited, pushing the sliding block 66 to slide upward, driving the connecting pipe 68 to move upward, connecting with the exhaust device 9, and exhausting air. The device 9 draws air in and directly passes it into the water in the water tank 61 through the connecting pipe 68 to humidify the drawn air. When the water in the water tank 61 evaporates, the humidity sensor 62 detects that the surrounding humidity has become low and sends an electrical signal to the controller 64. After receiving the electrical signal, the controller 64 controls the cylinder 63 to start, pushing the water tank 61 to slide outward and push the water tank 61 out. The water tank 61 slides against the side wall of the oxygen generator 4, driving the connecting pipe 68 to move. When the connecting pipe 68 moves to the triangle plate 615, its top edge is aligned with the triangle plate 615. The side wall of the water tank 61 slides, the triangular plate 615 pushes the connecting pipe 68 to move downward, driving the sliding block 66 to slide downward, compressing the support spring 67. At the same time, the side wall of the water tank 61 pushes the triangular block 614 to slide upward and then disengage. The extrusion block 611 is no longer pushed by the triangular block 614, and is reset by the elastic force of the fixed spring 612. Its inclined surface slides with the inclined surface of the stop block 610, pushing the stop block 610 to slide to the top of the connecting pipe 68, and at the same time compressing the reset spring 69, so that the stop block 610 limits the connecting pipe 68.

[0023] See also Figures 1-8On the basis of the above embodiment, in another embodiment of the present invention, a turbulence device for enhancing the mixing of air and water is provided in the humidifying device, and the turbulence device includes a fixing rod 71, a turbine 72, a fixing plate 73, a motor 74, a rotating rod 75 and a fan 76. The fixing rod 71 is fixedly connected to the bottom surface of the inner wall of the water storage tank 61, and the fixing rod 71 passes through the turbine 72, and the penetration is rotatably connected. The air extraction device 9 draws air into the water through the connecting pipe 68, and the air flow is sprayed on the outer wall of the turbine 72, driving the turbine 72 to rotate around the fixing rod 71, thereby affecting the water flow. Disturbance, the fixed plate 73 is fixedly connected to the side wall of the inner wall of the oxygen generator 4, the motor 74 is fixedly connected to the inner wall of the fixed plate 73, the motor 74 is electrically connected to the controller 64, and the controller 64 controls the motor 74 to turn off when receiving the electrical signal of the humidity sensor 62. When the water storage tank 61 is filled with water again, the humidity sensor 62 transmits an electrical signal to the controller 64, and the controller 64 controls the motor 74 to start. The rotating rod 75 is fixedly connected to the output end of the motor 74. When the motor 74 starts, the rotating rod 75 is driven to rotate. The fan 76 is fixedly connected to the rotating rod 75. The rod 75 is away from one end of the motor 74. When the rotating rod 75 rotates, it drives the fan 76 to rotate as well. The fan 76 rotates and is connected to the inner wall of the bottom end of the oxygen production box 4. The fan 76 rotates to further send the oxygen in the oxygen production box 4 into the oxygen supply pipe 2. When the air is drawn in through the exhaust device 9, the turbulence device cooperates with the connecting pipe 68 to directly draw the air under the water surface. The air flow drives the water flow to drive the turbine 72 to rotate around the fixed rod 71, disturbing the water surface and breaking up the bubbles, thereby increasing the contact area between the air and the water, accelerating the diffusion of water vapor molecules, and solving the problem of water vapor molecules. The invention solves the problem that after the air flow is directly introduced into the water surface, the air is likely to overflow directly through the bubbles, resulting in poor air humidification effect; while humidifying the mixed gas in the oxygen production box 4, the fixed plate 73, the motor 74 and the rotating rod 75 drive the fan 76 to rotate, thereby further sending the mixed gas of air and oxygen in the oxygen production box 4 into the oxygen supply pipe 2, avoiding the situation that only oxygen but no air enters the oxygen supply pipe 2 due to the greater density of oxygen than air, and solving the problem that direct oxygen supply easily leads to a high oxygen concentration in the oxygen supply pipe 2, which is not suitable for bio-fertilizer fermentation.

[0024] The interior of the oxygen generator 4 is provided with a control device for intermittent oxygen supply. The control device includes a sliding sleeve 81, a sealing plate 82, a sliding rod 83, a wave groove 84, a limit plate 85, a sliding plate 86, a moving block 87, a knocking block 88 and a limit block 89. The rotating rod 75 passes through the sliding sleeve 81 and is slidably connected at the penetration point. When the motor 74 drives the rotating rod 75 to rotate, the rotating rod 75 also drives the sliding sleeve 81 to rotate. The sealing plate 82 is fixedly connected to the outer wall of the upper end of the sliding sleeve 81. When the sliding sleeve 81 slides up and down, the sealing plate 82 is driven to rotate. The sealing plate 82 slides up and down. When the sealing plate 82 slides up, the connection port of the oxygen box 4 and the oxygen supply pipe 2 is exposed. When the sealing plate 82 slides down, the connection port of the oxygen box 4 and the oxygen supply pipe 2 is closed, so that the oxygen box 4 intermittently supplies oxygen to the oxygen supply pipe 2. The sliding rod 83 is fixedly connected to the outer wall of the sliding sleeve 81. The rotation of the sliding sleeve 81 drives the sliding rod 83 to rotate. The wave groove 84 is opened on the inner wall of the bottom end of the oxygen box 4. The end of the sliding rod 83 away from the sliding sleeve 81 is slidably connected to the inner wall of the wave groove 84. When the sliding rod 83 rotates, it fits the wave groove. The wave groove 84 slides, and the sliding sleeve 81 slides up and down along the wave groove 84. The limit plate 85 is fixedly connected to the bottom surface of the inner wall of the oxygen making box 4. The sliding plate 86 is slidably connected to the side wall of the limit plate 85. The sliding plate 86 is set in a shape with a middle protrusion and two ends drooping. When the sealing plate 82 slides upward, it pushes the sliding plate 86 to slide upward along the limit plate 85. The moving block 87 passes through the sliding plate 86 and is slidably connected at the penetration point. The knocking block 88 is fixedly connected to the side wall of the moving block 87 away from the sliding plate 86, and the sliding plate 86 drives the moving The block 87 and the knocking block 88 move upward, the limit block 89 is fixedly connected to the inner wall of the oxygen production box 4, and the side of the moving block 87 away from the sliding plate 86 is slidably connected to the limit block 89. The sliding plate 86 is set in a shape with a convex middle and drooping ends. Therefore, when the moving block 87 moves to the convex part of the limit block 89, it is squeezed by the limit block 89 and slides into the sliding plate 86. When the moving block 87 moves to the concave part of the limit block 89, it slides in the direction away from the sliding plate 86 due to gravity, driving the knocking block 88 to knock on the inner wall of the oxygen production box 4; When the motor 74 is started, the control device cooperates with the sliding sleeve 81, the sliding rod 83 and the wave groove 84 to drive the sealing plate 82 to slide up and down, so that the sealing plate 82 intermittently closes the connection between the oxygen supply pipe 2 and the oxygen production box 4, slowing down the rate at which the mixed gas in the oxygen production box 4 is transmitted to the oxygen supply pipe 2, increasing the contact time between oxygen and bio-fertilizer fermentation, thereby improving the utilization rate of oxygen and solving the problem of reduced utilization rate caused by continuous oxygen supply; When the sealing plate 82 slides up and down, it also drives the sliding plate 86 to slide up and down. In cooperation with the limit plate 85, the moving block 87 and the limit block 89 make the knocking block 88 repeatedly knock on the inside of the oxygen generator box 4, so that the oxygen generator box 4 drives the water storage tank 61 to vibrate, thereby promoting the broken bubbles to rise from the water surface, improving the efficiency of the bubble overflow, and solving the problem that the bubbles rise slowly from the water surface, resulting in uneven mixing of oxygen and air.

[0025] When this embodiment is working: the exhaust device 9 draws air into the water through the connecting pipe 68, and the air flow is sprayed on the outer wall of the turbine 72, driving the turbine 72 to rotate around the fixed rod 71, disturbing the water flow. When the controller 64 receives the electrical signal from the humidity sensor 62, it also controls the motor 74 to turn off. When the water storage tank 61 is filled with water again, the humidity sensor 62 transmits an electrical signal to the controller 64, and the controller 64 controls the motor 74 to start. The motor 74 starts and drives the rotating rod 75 to rotate. When the rotating rod 75 rotates, it drives the fan 76 to rotate as well, further delivering the air in the oxygen production box 4 into the oxygen supply pipe 2.

[0026] When the motor 74 drives the rotating rod 75 to rotate, the rotating rod 75 also drives the sliding sleeve 81 to rotate. When the sliding sleeve 81 rotates, it drives the sliding rod 83 to rotate around the central axis of the rotating rod 75. The end of the sliding rod 83 away from the sliding sleeve 81 is slidably connected with the wave groove 84 provided on the inner wall of the bottom end of the oxygen generator box 4. When the sliding sleeve 81 drives the sliding rod 83 to rotate, the sliding rod 83 also slides in accordance with the wave groove 84. Therefore, the sliding rod 83 drives the sliding sleeve 81 to slide up and down along the wave groove 84. When the sliding sleeve 81 slides up and down, it drives the sealing plate 82 to slide up and down. When the sealing plate 82 slides upward, the connection port between the oxygen generator box 4 and the oxygen supply pipe 2 is exposed. When the sealing plate 82 slides downward, the connection between the oxygen generator box 4 and the oxygen supply pipe 2 is closed, so that the oxygen generator box 4 intermittently supplies oxygen to the oxygen supply pipe 2. When the sealing plate 82 slides upward, it pushes the sliding plate 86 to slide upward along the limit plate 85. The sliding plate 86 drives the moving block 87 and the knocking block 88 to move upward. The sliding plate 86 is set in a shape with a middle protrusion and drooping ends. Therefore, when the moving block 87 moves to the protrusion of the limit block 89, it is squeezed by the limit block 89 and slides into the sliding plate 86. When the moving block 87 moves to the recessed position of the limit block 89, it slides in the direction away from the sliding plate 86 due to gravity, driving the knocking block 88 to knock on the inner wall of the oxygen generator box 4.
