Description

Technical Field

[0001] This application relates to the technical field of organic fertilizer production equipment, and in particular to an organic fertilizer fermentation aeration device. Background Technology

[0002] Organic fertilizer fermentation is a technology that uses microorganisms to decompose organic matter to produce fertilizer. It is suitable for treating organic materials such as livestock and poultry manure, straw, and kitchen waste.

[0003] Organic fertilizer fermentation is generally aerobic, and the oxygen supply is the main factor affecting the fermentation rate. In current technology, aeration devices are typically placed at the bottom of the fermentation tank, aerating upwards. If the fermentation tank is large and there is a large amount of raw material, this single aeration direction can easily lead to uneven oxygen distribution within the raw material, creating anaerobic zones. This not only produces unpleasant odors but also results in incomplete decomposition of the organic fertilizer, thus affecting its fertilizer efficiency. Utility Model Content

[0005] This application provides an organic fertilizer fermentation aeration device, including: a fermentation tank, a bottom aeration unit, and a side aeration unit; The bottom aeration unit includes a first high-pressure oxygen supply pump, a first air inlet main pipe, and multiple first aeration pipes. The air inlet in the middle of the first air inlet main pipe is connected to the outlet of the first high-pressure oxygen supply pump. One end of each of the multiple first aeration pipes is connected to the first air inlet main pipe. Multiple grooves are opened parallel to each other along the length of the bottom of the fermentation tank. The multiple first aeration pipes pass through the side wall of the fermentation tank and are embedded in the multiple grooves. Multiple first aeration cuts are opened on the top wall of the multiple first aeration pipes. The side aeration unit includes a second high-pressure oxygen supply pump, a second main air inlet pipe, multiple second aeration pipes, and an electric telescopic rod. The second high-pressure oxygen supply pump is located on the outside of the side of the fermentation tank. The middle air inlet of the second main air inlet pipe is connected to the outlet of the second high-pressure oxygen supply pump via a hose. One end of each of the multiple second aeration pipes is connected to the second main air inlet pipe. The fixed end of the electric telescopic rod is set at the same height as the second main air inlet pipe via a fixed bracket, and the telescopic end of the electric telescopic rod is connected to the middle of the side wall of the second main air inlet pipe. Side wall through holes are opened on the side wall of the fermentation tank near the side aeration unit, corresponding to the multiple second aeration pipes. Multiple second aeration slits are opened on the top wall of the multiple second aeration pipes.

[0006] Optionally, multiple first aeration pipes and multiple second aeration pipes are arranged vertically in the horizontal direction.

[0007] Optionally, multiple lateral aeration units are symmetrically arranged along the axial centerline of the fermentation tank, and the multiple symmetrically arranged lateral aeration units are staggered in the vertical direction.

[0008] Optionally, the side aeration unit is also connected to a traction structure, including an upper hanging lug, a telescopic spring, and a lower hanging lug; The upper hanging lug is fixedly connected to the side wall of the fermentation tank, and the lower hanging lug is fixedly connected to the top center of the second air intake pipe. The two ends of the telescopic spring are respectively hinged to the upper and lower hanging lugs.

[0009] Optionally, a baffle ring is provided on the outer periphery of the side wall through hole. The outer diameter of the baffle ring is fixedly connected to the outer periphery of the side wall through hole, and the inner diameter of the baffle ring is in contact with the outer periphery of the second aeration pipe.

[0010] Optionally, the aeration device is also equipped with a drainage unit, including multiple first aeration pipes, a drain valve, a drain pipe and a water collection tank. The diameter of the multiple first aeration pipes gradually decreases from the end closest to the first high-pressure oxygen supply pump to the end furthest from the first high-pressure oxygen supply pump, and the axial center lines of the multiple first aeration pipes are in the horizontal direction. Multiple first aeration pipes are equipped with drain valves at the bottom of one end near the first high-pressure oxygen supply pump. The outlet end of the drain valve is connected to the drain pipe and the water collection tank in sequence.

[0011] Optionally, a temperature sensor is installed inside the fermentation tank.

[0012] The organic fertilizer fermentation aeration device provided in this application achieves uniform aeration during the organic fertilizer fermentation process, and has the following advantages compared with the prior art: (1) By setting up bottom aeration units and side aeration units, when there are a lot of fermentation raw materials or the compost height is high, aeration is achieved simultaneously through the bottom aeration units and side aeration units, so that the organic fertilizer can be fully aerobic fermented, which helps the organic fertilizer to be completely decomposed, and thus improves the fertilizer efficiency of the organic fertilizer. The side aeration units are equipped with electric telescopic rods, which can be pushed out at any time when in use and retracted in time when not in use, avoiding the side aeration units from staying in the fermentation tank for a long time and affecting the use of other turning machines, discharge equipment, etc., making the operation of the device more convenient.

[0013] (2) By setting up a traction structure, horizontal assistance is provided for the side aeration unit during use. When the electric telescopic rod is turned on, the telescopic end of the electric telescopic rod extends and pushes the second air intake main pipe into the fermentation tank, thereby pushing multiple second aeration pipes horizontally into the fermentation tank. The second air intake main pipe is elastically connected to the fermentation tank by a telescopic spring, which prevents the second air intake main pipe from tilting downward under the action of gravity when moving horizontally, thus preventing the side aeration unit from shaking during the pushing process. The traction structure always has an upward traction force on the second air intake main pipe, thereby ensuring that the second air intake main pipe will not fall off when pushed forward or pulled back.

[0014] (3) By setting up a baffle ring, the organic fertilizer adhering to the outer periphery of the second aeration pipe is scraped off. When the side aeration unit is pulled out of the fermentation tank, the fermentation raw materials in the fermentation tank will not be carried out of the fermentation tank, thus ensuring the cleanliness of the second aeration pipe.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0019] like Figure 1 , Figure 2As shown, this application provides an organic fertilizer fermentation aeration device, including: a fermentation tank 1, a bottom aeration unit and a side aeration unit; The bottom aeration unit includes a first high-pressure oxygen supply pump 210, a first air inlet main pipe 220, and a plurality of first aeration pipes 230. The middle air inlet of the first air inlet main pipe 220 is connected to the outlet of the first high-pressure oxygen supply pump 210. One end of the plurality of first aeration pipes 230 is connected to the first air inlet main pipe 220. A plurality of grooves are provided parallel to each other along the length direction at the bottom of the fermentation tank 1. The plurality of first aeration pipes 230 pass through the side wall of the fermentation tank 1 and are embedded in the plurality of grooves. A plurality of first aeration cuts 231 are provided on the top wall of the plurality of first aeration pipes 230. The side aeration unit includes a second high-pressure oxygen supply pump 310, a second air inlet main pipe 320, multiple second aeration pipes 330, and an electric telescopic rod 340. The second high-pressure oxygen supply pump 310 is located on the outside of the side of the fermentation tank 1. The middle air inlet of the second air inlet main pipe 320 is connected to the outlet of the second high-pressure oxygen supply pump 310 through a hose 311. One end of the multiple second aeration pipes 330 is connected to the second air inlet main pipe 320. The fixed end of the electric telescopic rod 340 is set at the same height as the second air inlet main pipe 320 through a fixed bracket 350, and the telescopic end of the electric telescopic rod 340 is connected to the middle of the side wall of the second air inlet main pipe 320. Side wall through holes 110 are opened on the side wall of the fermentation tank 1 near the side aeration unit, corresponding to the multiple second aeration pipes 330. Multiple second aeration cuts 331 are opened on the top wall of the multiple second aeration pipes 330.

[0020] Specifically, in order to uniformly aerate the fermentation raw materials during the organic fertilizer fermentation process, the fermentation aeration device provided in this application is equipped with a bottom aeration unit and a side aeration unit. When there are a lot of fermentation raw materials or the compost height is high, aeration is achieved simultaneously through the bottom aeration unit and the side aeration unit, so that the organic fertilizer can fully undergo aerobic fermentation, which helps the organic fertilizer to fully decompose and improves the fertilizer efficiency.

[0021] The bottom aeration unit includes a first high-pressure oxygen supply pump 210, a first air inlet main pipe 220, and multiple first aeration pipes 230. The first high-pressure oxygen supply pump 210 is located outside the fermentation tank 1. By turning on the first high-pressure oxygen supply pump 210, high-pressure air is provided. The air passes through the first air inlet main pipe 220, then through the multiple first aeration pipes 230, and enters the fermentation raw material through multiple first aeration incisions 231, enabling the fermentation raw material to undergo aerobic fermentation. The end of the first aeration pipe 230 away from the first high-pressure oxygen supply pump 210 is in a closed state.

[0022] Multiple grooves are parallel to each other along the length of the bottom of the fermentation tank 1. Multiple first aeration pipes 230 pass through the side wall of the fermentation tank 1 and are embedded in the multiple grooves. Furthermore, the height of the grooves and the first aeration pipes 230 are the same. This avoids the first aeration pipes 230 being too high and affecting subsequent processes (such as turning the raw materials by a turning machine, or the discharge equipment colliding with the first aeration pipes 230 at the bottom of the fermentation tank 1 during discharge). At the same time, it avoids the first aeration pipes 230 being too low, causing organic fertilizer to fall into the gap between the first aeration pipes 230 and the grooves.

[0023] The side aeration unit includes a second high-pressure oxygen supply pump 310, a second main air inlet 320, multiple second aeration pipes 330, and an electric telescopic rod 340. The second main air inlet 320, multiple second aeration pipes 330, and the electric telescopic rod 340 are all horizontally arranged. When aeration is required from the side aeration unit, high-pressure air is supplied by the second high-pressure oxygen supply pump 310. The air flows through the second main air inlet 320. Simultaneously with activating the second high-pressure oxygen supply pump 310, the electric telescopic rod 340 is activated. The telescopic end of the electric telescopic rod 340 extends and pushes the second main air inlet... Pipe 320 moves towards the fermentation tank 1, causing multiple second aeration pipes 330 to enter the fermentation tank 1 horizontally. Air enters the fermentation raw material through the second air inlet pipe 320, multiple second aeration pipes 330, and finally through multiple second aeration inlets 331. This allows the fermentation raw material in the upper and middle parts of the fermentation tank 1 to undergo aerobic fermentation simultaneously with the fermentation raw material at the bottom, improving the uniformity of oxygen supply and promoting the uniformity of aerobic fermentation of organic fertilizer. There are no anaerobic zones, no foul odors are produced, and this ensures that the organic matter in the organic fertilizer is completely decomposed, thus guaranteeing the fertilizer efficiency. The end of the second aeration pipe 330 away from the second high-pressure oxygen supply pump 310 is in a closed state.

[0024] After aeration is complete, the electric telescopic rod 340 is activated again to retract, pulling the multiple second aeration pipes 330 back outside the fermentation tank 1. This electric telescopic rod 340 allows the side aeration units to be pushed out at any time when in use and retracted in time when not in use, avoiding the side aeration units from staying in the fermentation tank 1 for a long time and affecting the use of other turning machines and discharge equipment, making the operation of the device more convenient.

[0025] This application achieves uniform aeration during the organic fertilizer fermentation process through the aforementioned scheme. By setting up bottom and side aeration units, when there is a large amount of fermentation raw material or the compost height is high, simultaneous aeration through both units ensures uniform aeration of the organic fertilizer. This allows for sufficient aerobic fermentation, promoting complete decomposition and improving its fertilizer efficiency. The side aeration units, equipped with electrically operated telescopic rods, can be extended when in use and retracted when not in use, preventing them from remaining in the fermentation tank for extended periods and interfering with the operation of other equipment such as turners and discharge devices, thus making the operation of the device more convenient.

[0026] Optionally, the multiple first aeration pipes 230 and the multiple second aeration pipes 330 are arranged vertically in the horizontal direction for easy operation.

[0027] Optionally, multiple lateral aeration units are symmetrically arranged along the axial centerline of the fermentation tank 1, and the multiple symmetrically arranged lateral aeration units are staggered in the vertical direction.

[0028] Specifically, when the organic fertilizer is at a relatively high height, the side aeration units are arranged symmetrically on both sides, further improving the uniformity of aeration. At the same time, the side aeration units are staggered vertically to avoid collisions between the multiple second aeration pipes 330 on both sides, which is conducive to the efficient and stable operation of the device.

[0029] like Figure 3 As shown, optionally, the side aeration unit is also connected to a pulling structure, including an upper lifting lug 410, a telescopic spring 420 and a lower lifting lug 430. The upper hanging lug 410 is fixedly connected to the side wall of the fermentation tank 1, and the lower hanging lug 430 is fixedly connected to the top center of the second air intake pipe 320. The two ends of the telescopic spring 420 are respectively hinged to the upper hanging lug 410 and the lower hanging lug 430.

[0030] Specifically, the pulling structure provides horizontal assistance when using the side aeration unit. When the electric telescopic rod 340 is activated, its telescopic end extends and pushes the second air intake main pipe 320 towards the fermentation tank 1, thereby pushing multiple second aeration pipes 330 horizontally into the fermentation tank 1. A telescopic spring 420 elastically connects the second air intake main pipe 320 to the fermentation tank 1, preventing it from tilting downwards under gravity during horizontal movement and causing swaying during the side aeration unit's movement. The pulling structure always exerts an upward pulling force on the second air intake main pipe 320, ensuring it will not fall off when pushed forward or pulled back.

[0031] like Figure 4 As shown, optionally, a baffle ring 120 is provided on the outer periphery of the side wall through hole 110. The outer diameter of the baffle ring 120 is fixedly connected to the outer periphery of the side wall through hole 110, and the inner diameter of the baffle ring 120 is in contact with the outer periphery of the second aeration pipe 330.

[0032] Specifically, the baffle ring 120 is located at one end of the side wall through hole 110 inside the fermentation tank 1. When the multiple second aeration pipes 330 are horizontally withdrawn from the fermentation tank 1, the inner diameter of the baffle ring 120 acts as a scraper, scraping off the organic fertilizer adhering to the outer periphery of the second aeration pipes 330. With this setting, when the side aeration unit is pulled out of the fermentation tank 1, the fermentation raw materials in the fermentation tank 1 will not be carried out of the fermentation tank 1, ensuring the cleanliness of the second aeration pipes 330.

[0033] Furthermore, the retaining ring 120 can be made of metal or rubber.

[0034] like Figure 5 As shown, optionally, the aeration device is also provided with a drainage unit, including multiple first aeration pipes 230, a drain valve 510, a drain pipe 520 and a water collection tank 530. The diameter of the multiple first aeration pipes 230 gradually decreases from the end near the first high-pressure oxygen supply pump 210 to the end away from the first high-pressure oxygen supply pump 210, and the axial center lines of the multiple first aeration pipes 230 are in the horizontal direction. A drain valve 510 is provided at the bottom of one end of the first aeration pipe 230 near the first high-pressure oxygen supply pump 210. The outlet end of the drain valve 510 is connected to the drain pipe 520 and the water collection tank 530 in sequence.

[0035] Specifically, after aeration ends, when the first high-pressure oxygen supply pump 210 is stopped for a short period of time, a negative pressure environment will be temporarily formed in multiple first aeration pipes 230. This will draw a small amount of water vapor produced by fermentation into the first aeration pipes 230 and form water accumulation. Over time, this will corrode the pipes and will also hinder subsequent aeration. By setting up a drainage unit to drain this water, the fermentation efficiency of the organic fertilizer can be improved.

[0036] The diameter of the first aeration pipe 230 in the drainage unit gradually decreases from the end closest to the first high-pressure oxygen supply pump 210 to the end furthest from the first high-pressure oxygen supply pump 210, and the axial center lines of the multiple first aeration pipes 230 are horizontal. This arrangement makes the bottom of the first aeration pipe 230 an inclined surface. After aeration, the water in the first aeration pipe 230 flows from the end furthest from the first high-pressure oxygen supply pump 210 to the end closest to the first high-pressure oxygen supply pump 210. Simultaneously, a drain valve 510 is installed at the bottom of the first aeration pipe 230 near the first high-pressure oxygen supply pump 210. Opening the drain valve 510 allows the accumulated water to be collected in the water collection tank 530 through the drain pipe 520, ensuring that there is no water accumulation in the first aeration pipe 230 and preventing pipe corrosion. Furthermore, the drain valve 510 is a solenoid valve.

[0037] Furthermore, the diameter of the first aeration pipe 230 gradually decreases from the end closest to the first high-pressure oxygen supply pump 210 to the end furthest from the first high-pressure oxygen supply pump 210. This arrangement is beneficial for the air at the end of the first aeration pipe 230 to have better power to enter the fermentation raw materials during the aeration process, thereby promoting the power of the incoming air and the uniformity of aeration.

[0038] Furthermore, the gap between the first aeration pipe 230 and the groove in the fermentation tank 1 is filled with a metal plate to prevent organic fertilizer from entering the gap.

[0039] Optionally, a temperature sensor 6 is installed inside the fermentation tank 1.

[0040] Specifically, temperature sensor 6 is used to detect the temperature of the organic fertilizer in fermentation tank 1 in real time, so as to remind the operator whether to aerate the fermentation tank 1. When the temperature detected by temperature sensor 6 reaches the first preset temperature value, the first high-pressure oxygen supply pump 210 and the second high-pressure oxygen supply pump 310 are turned on for aeration. When the temperature detected by temperature sensor 6 reaches the second preset temperature value, the first high-pressure oxygen supply pump 210 and the second high-pressure oxygen supply pump 310 are turned off. The first preset temperature value is lower than the second preset temperature value.

[0041] The technical solution of this application will be illustrated in detail below with specific embodiments.

[0042] The operating procedure of the organic fertilizer fermentation aeration device in this embodiment is as follows: When the temperature detected by temperature sensor 6 reaches the first preset temperature (45-50℃), aeration is required. The first high-pressure oxygen pump 210 is activated to provide high-pressure air. The air passes through the first air intake main pipe 220, then through multiple first aeration pipes 230, and enters the fermentation material through multiple first aeration inlets 231, allowing the fermentation material to undergo aerobic fermentation. High-pressure air is also provided by the second high-pressure oxygen pump 310. The air passes through the second air intake main pipe 320, and simultaneously with the activation of the second high-pressure oxygen pump 310, the electric telescopic rod 340 is activated. The telescopic end of the electric telescopic rod 340 extends and pushes the second air intake main pipe 320 into the fermentation tank 1, causing multiple second aeration pipes 330 to enter the fermentation tank 1 horizontally. Air then enters the fermentation material through the second air intake main pipe 320, multiple second aeration pipes 330, and finally through multiple second aeration inlets 331, thus allowing the fermentation material in the upper and lower parts of the fermentation tank 1 to undergo aerobic fermentation simultaneously with the fermentation material at the bottom. Multiple first aeration pipes 230 and multiple second aeration pipes 330 are arranged vertically in the horizontal direction.

[0043] When the temperature detected by temperature sensor 6 reaches the second preset temperature value (60-65℃), aeration is completed. First, turn off the first high-pressure oxygen supply pump 210, then start the electric telescopic rod 340 to retract and pull the multiple second aeration pipes 330 back outside the fermentation tank 1, and then turn off the second high-pressure oxygen supply pump 310.

[0044] After shutting down the first high-pressure oxygen supply pump 210 and the second high-pressure oxygen supply pump 310, open the drain valve 510 to collect the accumulated water into the water collection tank 530 through the drain pipe 520, ensuring that there is no water accumulation in the first aeration pipe 230.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
