Description

Technical Field

[0001] The present application relates to the technical field of organic fertilizer fermentation, and in particular to an aeration device and an aeration system. Background Art

[0002] Animal husbandry and agricultural production activities will generate a large amount of livestock and poultry waste and other industrial and agricultural organic waste. In order to treat these organic wastes harmlessly, utilize them as resources, and make them into organic fertilizers, these wastes need to be aerobically fermented, that is, aerobically fermented in a fermentation tank.

[0003] During the fermentation process, the fermentation tank needs to be continuously supplied with oxygen to maintain the normal metabolic activities of the microorganisms in the mailing waste and ensure the stability and efficiency of the fermentation effect. For this purpose, an aeration device is usually installed at the bottom of the fermentation tank to evenly distribute the air into the fermentation tank through multiple aeration devices. In actual applications, some aeration ports of the aeration device may be blocked due to accumulation of organic waste or other impurities. Multiple aeration ports are connected to the same air pipe. One or several of the multiple aeration ports are blocked. The air flow rate in the air pipe is constant. For movable aeration ports (the size of the aeration ports can increase with the increase of the air pressure inside the air pipe), when the internal air pressure of the air pipe increases, the size of the unblocked aeration ports increases accordingly, and the air in the air pipe will preferentially pass through the unblocked aeration ports. The increase in air pressure inside the air pipe is small, which may cause the aeration area corresponding to the unblocked aeration ports to be in an over-aerated state. The blocked aeration ports are difficult to flush out the debris blocking themselves when the internal air pressure of the air pipe is low, forming a vicious cycle in which more and more debris accumulates at the blocked aeration ports, resulting in a slower fermentation rate and poorer fermentation effect in the aeration area corresponding to the blocked aeration ports, which ultimately leads to uneven aeration effect in various areas of the fermentation tank and reduced aeration efficiency of the entire aeration system. Utility Model Content

[0004] The purpose of the present application is to provide an aeration device and an aeration system to solve the above problems. The aeration device can reduce the risk that the aeration port is difficult to flush open after being blocked, so that the fermentation process of organic waste in the area corresponding to the aeration port proceeds normally.

[0005] In a first aspect, the present application provides an aeration device for releasing air in a pipeline into a fermentation tank, the aeration device comprising a plurality of aeration mechanisms, the plurality of aeration mechanisms being evenly arranged along the extension direction of the pipeline, the aeration mechanisms comprising a fixed component and a movable component; the fixed component being fixedly mounted on the pipeline, and the fixed component being connected to the pipeline, the fixed component being provided with a first aeration port; the movable component being movably mounted on the inner side of the fixed component, the movable component being provided with a second aeration port; wherein the first aeration port and the second aeration port are at least partially connected, the partial space between the fixed component and the movable component being an active cavity, the movable component being configured to move along the length direction of the fixed component when the internal pressure of the active cavity reaches a certain threshold, and in the length direction of the fixed component, the second aeration port facing one end of the pipeline is not lower than the first aeration port.

[0006] In the technical solution of the embodiment of the present application, the aeration device includes a plurality of aeration mechanisms, and the plurality of aeration mechanisms are evenly arranged along the extension direction of the pipeline, that is, in the extension direction of the pipeline, the interval between every two adjacent aeration mechanisms in the plurality of aeration mechanisms is equal, and each aeration mechanism can input air corresponding to the organic waste in an area of ​​a fixed size, so that the organic waste in the area can obtain relatively sufficient oxygen, thereby carrying out continuous and efficient fermentation activities;

[0007] The fixed component is fixedly installed on the pipeline, and the fixed component is connected to the pipeline, and the fixed component is provided with a first aeration port; the movable component can be movably installed on the fixed component, the movable component is connected to the fixed component, and the movable component is provided with a second aeration port; wherein the first aeration port and the second aeration port are at least partially connected, the fixed component and the movable component enclose an active cavity, the size of the active cavity changes with the movement of the movable component, and the movable component is configured to move along the length direction of the fixed component when the internal pressure of the active cavity reaches a certain threshold (the threshold mentioned in this application is the value when the air pressure pushes the active component to move, not a fixed value). As the movable component moves, the connection area between the second aeration port and the first aeration port will increase or decrease. In the initial state, the pressure in the active cavity of the pipeline and each aeration mechanism is equal, the first aeration port is completely connected to the second aeration port (that is, the connection is the largest), when the connection between the first aeration port and the second aeration port of any one or more of the multiple aeration mechanisms is blocked by organic waste. Due to the reduction of the pressure relief outlet, the air pressure in the pipeline increases, which drives the air pressure (i.e., the internal pressure) in the sealed cavity of the unblocked aeration mechanism to increase, thereby pushing the movable component to move in the direction away from the pipeline along the length direction of the fixed component, so that the size of the connection between the first aeration port and the second aeration port is reduced, and the amount of gas that can pass through the connection is reduced, thereby further increasing the air pressure in the pipeline, driving the air pressure in the active cavity of the blocked aeration mechanism to increase, and the force of the gas in the active cavity of the blocked aeration mechanism acting on the organic waste blocking the connection between the first aeration port and the second aeration port of the aeration mechanism increases until the organic waste at the connection is flushed open, and the gas in the active cavity can quickly pass through the connection between the first aeration port and the second aeration port, reducing the air pressure in the pipeline and the active cavity of each aeration mechanism, so that the aeration device provided by the present application can operate normally, reducing the risk of the organic waste in the corresponding area not being able to obtain sufficient oxygen and reducing the fermentation efficiency due to the aeration mechanism being blocked for a long time;

[0008] In the length direction of the fixed component, the second aeration port is not lower than the first aeration port at one end of the pipeline, so that when the movable component moves due to excessive air pressure in the pipeline and the movable cavity, the size of the connection between the first aeration port and the second aeration port gradually decreases, thereby reducing the amount of air released from the connection between the first aeration port and the second aeration port, and steadily increasing the air pressure inside the pipeline and each aeration mechanism.

[0009] In some embodiments, there are multiple first aeration ports, and the multiple first aeration ports are arranged on the fixed component around the length direction of the fixed component as the axis; there are multiple second aeration ports, and the multiple second aeration ports are arranged on the movable component around the length direction of the fixed component as the axis, and one second aeration port is connected to one or more first aeration ports.

[0010] In the technical solution of the embodiment of the present application, the number of the first aeration ports and the second aeration ports are both multiple, and the multiple first aeration ports and the multiple second aeration ports are all arranged around the length direction of the fixed component as the axis. On the one hand, the aeration mechanism can discharge air in all directions on a plane perpendicular to the length direction of the fixed component, and the organic waste surrounding the aeration mechanism can receive sufficient oxygen, thereby increasing the coverage area of ​​the operation of a single aeration mechanism, so that a small number of aeration mechanisms can meet the oxygen conditions required for the fermentation of more organic wastes, thereby reducing the number of aeration mechanisms required to be arranged in a unit space and reducing the use cost of the aeration device; on the other hand, the aeration mechanism can discharge air in all directions on a plane perpendicular to the length direction of the fixed component. When a part of the first aeration port or the second aeration port of a certain aeration mechanism is blocked by organic waste, the first aeration port and the second aeration port of another part of the aeration mechanism can continue to operate, so that the fermentation process of the surrounding organic waste can continue;

[0011] A second aeration port is connected to one or more first aeration ports, and the size or number of the first aeration ports connected to each second aeration port can be adjusted by actively rotating the movable component, thereby changing the amount of air released by the aeration mechanism per unit time to meet the fermentation requirements of organic waste of different compositions or quantities.

[0012] In some embodiments, the movable component includes a top wall and a side wall, one end of the side wall is connected to the top wall, the side wall extends toward the pipe along the length direction of the fixed component, the side wall is adapted to the shape of the inner wall of the fixed component and the side wall is close to the inner wall of the fixed component, and the second aeration port is arranged on the side wall.

[0013] In the technical solution of the embodiment of the present application, the movable component includes a top wall and a side wall, the second aeration port is arranged on the side wall, and the top wall can enclose an movable cavity of variable size with the inner wall of the fixed component, so as to adjust the position of the second aeration port inside the fixed component, and when blockage occurs, the size of the connection between the first aeration port and the second aeration port can be timely reduced, so that the air pressure in the pipeline and the movable cavity is timely increased, and the organic waste blocking the connection between the first aeration port and the second aeration port is flushed away, so that the blocked aeration mechanism can continue to operate normally;

[0014] On the one hand, as the blockage time increases, the amount of organic waste accumulated at the blockage will gradually increase, and the side wall is adapted in shape to the inner wall of the fixed component and the side wall is in close contact with the inner wall of the fixed component, thereby reducing the risk of air passing through between the side wall and the inner wall of the fixed component, causing the rate of increase or decrease of the air pressure in the active cavity to slow down, so that the air pressure in the active cavity can be increased in time to quickly flush out the organic waste blocking the connection between the first aeration port and the second aeration port, thereby reducing the risk that the connection between the first aeration port and the second aeration port is difficult to flush out due to the excessive amount of organic waste blocking the connection; on the other hand, the side wall is adapted in shape to the inner wall of the fixed component and the side wall is in close contact with the inner wall of the fixed component, thereby reducing the gap between the side wall and the inner wall of the fixed component, thereby reducing the risk of organic waste entering between the side wall and the inner wall of the fixed component and affecting the normal activity of the active component.

[0015] In some embodiments, the fixing assembly includes a main body and a cover body, the main body has a first opening extending along the length direction of the fixing assembly, and the cover body is used to close the first opening; the aeration mechanism also includes a limiting assembly, the limiting assembly includes a limiting rod and a limiting plug, the top wall is provided with a through hole for the limiting rod to pass through, one end of the limiting rod is connected to the side of the cover body facing the first opening, and the other end of the limiting rod is connected to the limiting plug, and the limiting plug is located in the movable cavity; the through hole and the limiting rod are sealed.

[0016] In the technical solution of the embodiment of the present application, the fixed component includes a main body and a cover body, and the main body and the cover body are designed as separate parts, which is convenient for disassembling the fixed component to maintain and adjust its internal structure and the movable component limiting component located on the inner side of the fixed component; the limiting component includes a limit rod and a limit plug, one end of the limit rod is connected to the side of the cover body facing the first opening, and the other end of the limit rod is connected to the limit plug, the limit plug is located in the active cavity, and the size of the limit plug is larger than the size of the through hole. When the aeration device provided by the present application is not in a working state, the movable component can move along the limit rod until it is hung by the limit plug. On the one hand, it prevents the movable component from moving to the position where the fixed component is connected to the pipeline and blocking it. On the other hand, it prevents the movable component from moving at a faster speed along the length direction of the fixed component and colliding with the position where the fixed component is connected to the pipeline when the air pressure in the active cavity decreases rapidly after the pipeline stops supplying gas, thereby reducing the risk of damage to the movable component and the fixed component due to collision.

[0017] In some embodiments, the length direction of the limiting rod is parallel to the length direction of the fixing component; in the length direction of the fixing component, the dimension between the cover body and the limiting plug is H1, the dimension between the limiting plug and the top wall is H2, and the dimension of the top wall is h, satisfying H1>H2+h.

[0018] In the technical solution of the embodiment of the present application, the length direction of the limit rod is parallel to the length direction of the fixed component. The limit rod can reduce the risk of the top wall deviating from the length direction of the fixed component or tilting when moving by limiting the movable direction of the top wall; in the length direction of the fixed component, the dimension between the cover body and the limit plug is H1, the dimension between the limit plug and the top wall is H2, and the dimension of the top wall is h. When H1>H2+h is satisfied, there is a gap between the top wall and the cover body, and the movable cavity can adjust its size in time according to the air pressure inside itself, so that the blocked aeration mechanism can promptly flush out the organic waste blocking itself.

[0019] In some embodiments, the limiting component further includes an elastic member, both ends of which are respectively connected to the cover body and the top wall, and a dimension of the elastic member in the length direction of the fixing component is H3, satisfying H3≤H1+h.

[0020] In the technical solution of the embodiment of the present application, the limiting component also includes an elastic member, and the two ends of the elastic member are respectively connected to the cover body and the top wall, and the two ends of the elastic member can be respectively abutted against the cover body and the top wall. On the one hand, when the aeration device provided by the present application is not in a working state, the elastic member can press the top wall against the limit plug, thereby reducing the risk that the movable component moves by itself and causes its own position to deviate from the standby state and cannot return to its position when starting operation; on the other hand, the larger the elastic coefficient of the elastic member, the greater the elastic force applied by the elastic member on the movable component, and the greater the air pressure in the movable chamber required for the movable component to move and push the elastic member to contract. When the aeration device works normally, the greater the air pressure in the active chamber, the faster the rate at which the gas in the active chamber passes through the connection between the first aeration port and the second aeration port. In summary, the rate at which the aeration mechanism outputs gas can be adjusted by replacing elastic members with different elastic coefficients to meet the aeration requirements under different working environments; the dimension of the elastic member in the length direction of the fixed component is H3, and when H3≤H1+h is satisfied, the elastic member is in a contracted state and can continuously apply elastic force to the top wall.

[0021] In some embodiments, a convex ring is disposed on the surface of the cover body facing the main body, and the convex ring extends into the main body and fits with the inner wall of the main body.

[0022] In the technical solution of the embodiment of the present application, the cover body is provided with a convex ring, which extends into the main body and is adapted to the inner wall of the main body. On the one hand, the cooperation between the convex ring and the inner wall of the main body can increase the connection stability between the cover body and the main body and reduce the risk of the two separating by themselves; on the other hand, when connecting the main body and the cover body, the cooperation between the convex ring and the main body can achieve rapid positioning and connection of the main body and the cover body, reducing the operational difficulty when installing the main body and the cover body.

[0023] In some embodiments, the number of limiting components is plural.

[0024] In the technical solution of the embodiment of the present application, when the inner wall of the main body is cylindrical, the side wall that fits the inner wall of the main body is also cylindrical, the side wall is coaxial with the inner wall of the main body, and the number of limiting components is multiple, which can limit the rotation of the side wall of the movable component relative to the inner wall of the main body, thereby reducing the risk of the connection between the second aeration port and the first aeration port increasing or decreasing due to the self-rotation of the side wall, which is inconsistent with the current working environment.

[0025] In a second aspect, the present application provides an aeration system for inputting air into a fermentation tank containing organic waste, the aeration system comprising an air intake pump, an air pipe and the aeration device of the first aspect; the air intake pump is arranged on the outside of the fermentation tank; one end of the air pipe is connected to the air intake end of the air intake pump, and the other end of the air pipe extends to the inside of the fermentation tank, the air pipe is arranged close to the bottom of the fermentation tank, and the air pipe can be covered by the organic waste in the fermentation tank; the aeration device is arranged on the air pipe, and the aeration device is arranged on the inside of the fermentation tank.

[0026] In the technical solution of the embodiment of the present application, the aeration system includes an air intake pump, an air pipe and the aeration device mentioned above. The air intake pump inputs air into the air pipe, and releases the air into the fermentation tank through the aeration device on the air pipe to meet the fermentation needs of organic waste. Under normal circumstances, when air flows in a curved pipe, the flow rate of the air at the bend of the pipe will slow down. The air pipe is arranged straight in the fermentation tank, so that the air entering the air pipe can continue to flow at a high speed, thereby reaching various parts of the air pipe more quickly, reducing the risk of uneven air pressure in various parts of the air pipe causing excessive air pressure in local areas to damage the air pipe.

[0027] In some embodiments, there are multiple air intake pumps and multiple air pipes, and the multiple air intake pumps correspond one-to-one to the multiple air pipes. The air pipes extend along a first direction in the fermentation tank, and the multiple air pipes are arranged in the fermentation tank along a second direction. The multiple aeration mechanisms of the multiple air pipes are evenly distributed in the fermentation tank in an array, and the first direction is perpendicular to the second direction.

[0028] In the technical solution of the embodiment of the present application, the air pipe extends along a first direction in the fermentation tank, and multiple air pipes are arranged in the fermentation tank along a second direction. Multiple aeration mechanisms of the multiple air pipes are evenly distributed in the fermentation tank in an array, so that organic waste in each area of ​​the fermentation tank can have corresponding aeration mechanisms to input air, thereby improving the overall fermentation efficiency of organic waste in the fermentation tank.

[0047] The present application is further described below in conjunction with the accompanying drawings, but the protection scope of the present application is not limited to the following description.

[0048] like Figure 2 to Figure 9 As shown, the present application provides an aeration device 1 for releasing air in a pipeline into a fermentation tank 2, the aeration device 1 comprises a plurality of aeration mechanisms 10, the plurality of aeration mechanisms 10 are evenly arranged along the extension direction of the pipeline, the aeration mechanism 10 comprises a fixed component 100 and a movable component 101; the fixed component 100 is fixedly installed on the pipeline, and the fixed component 100 is communicated with the pipeline, and the fixed component 100 is provided with a first aeration port 1000; the movable component 101 can be movably installed on the inner side of the fixed component 100, and the movable component 101 is provided with a second aeration port 1010; wherein the first aeration port 1000 and the second aeration port 1010 are at least partially communicated, the partial space of the fixed component 100 between the pipeline and the movable component 101 is an active cavity 102, the movable component 101 is configured to move along the length direction of the fixed component 100 when the internal pressure of the active cavity 102 reaches a certain threshold, and in the length direction of the fixed component 100, the second aeration port 1010 is not lower than the first aeration port 1000 toward one end of the pipeline.

[0049] The pipeline mentioned in the present application is a pipeline for inputting air into the fermentation tank 2. The fixed component 100 may include a first tube 1003 and a main body 1001. The axis of the first tube 1003 is parallel to the axis of the pipeline. The first tube 1003 is connected to the pipeline. One end of the main body 1001 is connected to the first tube 1003. The movable component 101 can be movably arranged on the inner side of the main body 1001, and the first aeration port 1000 is arranged on the main body 1001.

[0050] The waste organic matter mentioned in this application includes but is not limited to livestock and poultry manure, hair and other waste materials left over from agricultural and animal husbandry industrial activities that can be used for organic fertilizer fermentation.

[0051] The size of the first aeration port 1000 may be larger than that of the second aeration port 1010 ; or, the size of the first aeration port 1000 may be equal to that of the second aeration port 1010 ; or, the size of the first aeration port 1000 may be smaller than that of the second aeration port 1010 .

[0052] When the movable component 101 moves along the length direction of the fixed component 100 , the staggered portion between the first aeration port 1000 and the second aeration port 1010 can be blocked by the movable component 101 , and the staggered portion between the second aeration port 1010 and the first aeration port 1000 can be blocked by the fixed component 100 .

[0053] The aeration device 1 includes a plurality of aeration mechanisms 10, which are evenly arranged along the extension direction of the pipeline, that is, in the extension direction of the pipeline, the interval between every two adjacent aeration mechanisms 10 in the plurality of aeration mechanisms 10 is equal, and each aeration mechanism 10 can input air into the organic waste in a region of a fixed size, so that the organic waste in the region can obtain relatively sufficient oxygen, thereby carrying out continuous and efficient fermentation activities;

[0054] The fixed component 100 is fixedly installed on the pipeline, and the fixed component 100 is connected to the pipeline, and the fixed component 100 is provided with a first aeration port 1000; the movable component 101 can be movably installed on the fixed component 100, and the movable component 101 is connected to the fixed component 100, and the movable component 101 is provided with a second aeration port 1010; wherein the first aeration port 1000 and the second aeration port 1010 are at least partially connected, and the fixed component 100 and the movable component 101 enclose an active cavity 102, and the size of the active cavity 102 changes with the movement of the movable component 101, and the movable component 101 is configured to move in the active cavity 102. When the internal pressure of the fixed component 100 reaches a certain threshold value (the threshold value mentioned in this application is the value when the air pressure pushes the movable component 101 to move, not a fixed value), it moves along the length direction of the fixed component 100. As the movable component 101 moves, the connecting area between the second aeration port 1010 and the first aeration port 1000 will increase or decrease. In the initial state, the pressure in the active chamber 102 of the pipeline and each aeration mechanism 10 is equal, and the first aeration port 1000 is completely connected with the second aeration port 1010 (that is, the connecting point is the largest). When any one or more of the first aeration ports 1000 and 1010 of the plurality of aeration mechanisms 10 are connected, the connecting area between the second aeration port 1010 and the first aeration port 1000 will increase or decrease. When the connection of the second aeration port 1010 is blocked by organic waste, the air pressure in the pipeline increases due to the reduction of the pressure relief outlet, which drives the air pressure (i.e., the internal pressure) in the sealed cavity of the aeration mechanism 10 that is not blocked to increase, thereby pushing the movable component 101 to move along the length direction of the fixed component 100 in the direction away from the pipeline, so that the size of the connection between the first aeration port 1000 and the second aeration port 1010 is reduced, and the amount of gas that can pass through the connection is reduced, thereby further increasing the air pressure in the pipeline, driving the air pressure in the active cavity 102 of the blocked aeration mechanism 10 to increase, and the blocked aeration mechanism 10 is released. The force of the gas in the active cavity 102 of the aeration mechanism 10 on the organic waste blocking the connection between the first aeration port 1000 and the second aeration port 1010 of the aeration mechanism 10 increases until the organic waste at the connection is flushed away, and the gas in the active cavity 102 can quickly pass through the connection between the first aeration port 1000 and the second aeration port 1010, thereby reducing the air pressure in the pipeline and the active cavity 102 of each aeration mechanism 10, so that the aeration device 1 provided in the present application can operate normally, reducing the risk of the organic waste in the corresponding area not being able to obtain sufficient oxygen and reducing the fermentation efficiency due to the aeration mechanism 10 being blocked for a long time;

[0055] In the length direction of the fixed component 100, the second aeration port 1010 is not lower than the first aeration port 1000 toward one end of the pipeline, so that when the movable component 101 moves due to excessive air pressure in the pipeline and the movable chamber 102, the size of the connection between the first aeration port 1000 and the second aeration port 1010 gradually decreases, thereby reducing the amount of air released from the connection between the first aeration port 1000 and the second aeration port 1010, and steadily increasing the air pressure inside the pipeline and each aeration mechanism 10.

[0056] In some embodiments, a filter screen is provided at the first aeration port 1000 and / or the second aeration port 1010, and the filter screen can block organic waste from entering the aeration mechanism 10 or causing blockage inside the pipe connected to the aeration mechanism 10, so that the aeration device 1 can continue to operate normally.

[0057] According to some embodiments of the present application, Figure 5 As shown, there are multiple first aeration ports 1000, which are arranged on the fixed component 100 with the length direction of the fixed component 100 as the axis; there are multiple second aeration ports 1010, which are arranged on the movable component 101 with the length direction of the fixed component 100 as the axis, and one second aeration port 1010 is connected to one or more first aeration ports 1000.

[0058] The number of the first aeration ports 1000 may be two, three, four, five, six, seven, eight, nine, ten or more.

[0059] The number of the second aeration ports 1010 may be two, three, four, five, six, seven, eight, nine, ten or more.

[0060] When the size and shape of the first aeration port 1000 are the same as the size and shape of the second aeration port 1010, one first aeration port 1000 can be connected to one second aeration port 1010 and the positions can correspond; when the size of the first aeration port 1000 is larger than the size of the second aeration port 1010, one first aeration port 1000 can be set corresponding to multiple second aeration ports 1010; when the size of the first aeration port 1000 is smaller than the size of the second aeration port 1010, one second aeration port 1010 can be set corresponding to multiple first aeration ports 1000.

[0061] The number of the first aeration ports 1000 and the second aeration ports 1010 are both multiple, and the multiple first aeration ports 1000 and the multiple second aeration ports 1010 are all arranged around the length direction of the fixed component 100 as the axis. On the one hand, the aeration mechanism 10 can exhaust air in all directions on a plane perpendicular to the length direction of the fixed component 100, and the organic waste surrounding the aeration mechanism 10 can receive sufficient oxygen, thereby increasing the coverage area of ​​a single aeration mechanism 10, so that a smaller number of aeration mechanisms 10 can meet the fermentation needs of more organic waste. The required oxygen conditions are achieved, thereby reducing the number of aeration mechanisms 10 required to be arranged in a unit space and reducing the use cost of the aeration device 1; on the other hand, the aeration mechanism 10 can discharge air in all directions on a plane perpendicular to the length direction of the fixing component 100. When a part of the first aeration port 1000 or the second aeration port 1010 of a certain aeration mechanism 10 is blocked by organic waste, the first aeration port 1000 and the second aeration port 1010 of another part of the aeration mechanism 10 can continue to operate, so that the fermentation process of the surrounding organic waste can continue;

[0062] A second aeration port 1010 is connected to one or more first aeration ports 1000, and the size or number of the first aeration ports 1000 connected to each second aeration port 1010 can be adjusted by rotating the movable component 101, thereby changing the amount of air released by the aeration mechanism 10 per unit time to meet the fermentation requirements of organic waste of different compositions or quantities.

[0063] According to some embodiments of the present application, Figure 7 and Fig. 9 As shown, the movable component 101 includes a top wall 1011 and a side wall 1013, one end of the side wall 1013 is connected to the top wall 1011, the side wall 1013 extends toward the pipeline along the length direction of the fixed component 100, the side wall 1013 is adapted to the shape of the inner wall of the fixed component 100 and the side wall 1013 is tightly attached to the inner wall of the fixed component 100, and the second aeration port 1010 is arranged on the side wall 1013.

[0064] When the internal air pressure of the active chamber 102 is maximum, the size of the active chamber 102 is maximum. In the length direction of the fixed component 100, the end of the side wall 1013 away from the top wall 1011 is closer to the pipeline than the first aeration port 1000, so that the area other than the part where the first aeration port 1000 is connected to the second aeration port 1010 can be blocked by the active component 101.

[0065] The movable component 101 includes a top wall 1011 and a side wall 1013. The second aeration port 1010 is arranged on the side wall 1013. The top wall 1011 can enclose an movable cavity 102 of variable size with the inner wall of the fixed component 100, so as to adjust the position of the second aeration port 1010 inside the fixed component 100. When blockage occurs, the size of the connection between the first aeration port 1000 and the second aeration port 1010 can be reduced in time, so that the air pressure in the pipeline and the movable cavity 102 can be increased in time, and the organic waste blocking the connection between the first aeration port 1000 and the second aeration port 1010 can be flushed away, so that the blocked aeration mechanism 10 can continue to operate normally.

[0066] On the one hand, as the blockage time increases, the amount of organic waste accumulated at the blockage will gradually increase. The side wall 1013 is adapted to the shape of the inner wall of the fixed component 100 and the side wall 1013 is close to the inner wall of the fixed component 100, which reduces the risk of air passing through the side wall 1013 and the inner wall of the fixed component 100, resulting in a slowdown in the rate of increase or decrease of the air pressure in the active chamber 102, so that the air pressure in the active chamber 102 can be increased in time, thereby quickly removing the blockage of the first aeration port 1000 and the second aeration port 1010. The organic waste at the connection is flushed open, reducing the risk of the connection between the first aeration port 1000 and the second aeration port 1010 being difficult to flush open due to an excessive amount of blocked organic waste; on the other hand, the side wall 1013 is adapted to the shape of the inner wall of the fixed component 100 and the side wall 1013 is tightly attached to the inner wall of the fixed component 100, reducing the gap between the side wall 1013 and the inner wall of the fixed component 100, reducing the risk of organic waste entering between the side wall 1013 and the inner wall of the fixed component 100 and affecting the normal activity of the movable component 101.

[0067] According to some embodiments of the present application, Figure 3 to Figure 9 As shown, the fixing assembly 100 includes a main body 1001 and a cover body 1002, the main body 1001 has a first opening 1004 extending along the length direction of the fixing assembly 100, and the cover body 1002 is used to close the first opening 1004; the aeration mechanism 10 also includes a limiting assembly 102, the limiting assembly 102 includes a limiting rod 1020 and a limiting plug 1021, the top wall 1011 is provided with a through hole 1012 for the limiting rod 1020 to pass through, one end of the limiting rod 1020 is connected to a side of the cover body 1002 facing the first opening 1004, and the other end of the limiting rod 1020 is connected to the limiting plug 1021, and the limiting plug 1021 is located in the active cavity 102; the through hole 1012 and the limiting rod 1020 are sealed. Connection.

[0068] The cover 1002 and the main body 1001 may be detachably connected.

[0069] The size of the cover 1002 may be greater than or equal to the size of the first opening 1004 .

[0070] The limiting plug 1021 can be a nut, and the end of the limiting rod 1020 away from the cover body 1002 is provided with a thread for adapting to the limiting plug 1021; or, the limiting plug 1021 can be an annular structural part, the limiting plug 1021 is sleeved on the limiting rod 1020, and the limiting plug 1021 and the limiting part are interference fit.

[0071] The fixing assembly 100 includes a main body 1001 and a cover body 1002. The main body 1001 and the cover body 1002 are designed to be separated, so that the fixing assembly 100 can be disassembled to maintain and adjust its internal structure and the movable assembly 101 located inside the fixing assembly 100 and the limiting assembly 102; the limiting assembly 102 includes a limiting rod 1020 and a limiting plug 1021, one end of the limiting rod 1020 is connected to a side of the cover body 1002 facing the first opening 1004, and the other end of the limiting rod 1020 is connected to the limiting plug 1021, and the limiting plug 1021 is located in the movable cavity 102, and the size of the limiting plug 1021 is The movable component 101 is larger than the size of the through hole 1012. When the aeration device 1 provided in the present application is not in a working state, the movable component 101 can move along the limiting rod 1020 until it is hung by the limiting plug 1021. On the one hand, it can prevent the movable component 101 from moving to the position where the fixed component 100 is connected to the pipeline to block it. On the other hand, it can prevent the movable component 101 from moving at a fast speed along the length direction of the fixed component 100 and colliding with the position where the fixed component 100 is connected to the pipeline when the air pressure in the active chamber 102 decreases rapidly after the pipeline stops supplying gas, thereby reducing the risk of damage to the movable component 101 and the fixed component 100 due to collision.

[0072] According to some embodiments of the present application, Figure 7 and Fig. 9 As shown, the length direction of the limiting rod 1020 is parallel to the length direction of the fixing component 100; in the length direction of the fixing component 100, the dimension between the cover body 1002 and the limiting plug 1021 is H1, the dimension between the limiting plug 1021 and the top wall 1011 is H2, and the dimension of the top wall 1011 is h, satisfying H1>H2+h.

[0073] When H1=H2+h, the top wall 1011 contacts the cover body 1002, and the cover body 1002 limits the movement of the top wall 1011. On the one hand, the size of the active cavity 102 is constant, and the function of adjusting the size of the connection between the first aeration port 1000 and the second aeration port 1010 is lost. On the other hand, the gas pressure inside the active cavity 102 directly acts on the cover body 1002 through the top wall 1011, and there is a risk of damage to the cover body 1002 and the top wall 1011 pushing the cover body 1002 away from the main body 1001, causing air leakage.

[0074] The length direction of the limiting rod 1020 is parallel to the length direction of the fixing component 100. The limiting rod 1020 can reduce the risk of the top wall 1011 deviating from the length direction of the fixing component 100 or tilting when moving by limiting the movable direction of the top wall 1011; in the length direction of the fixing component 100, the dimension between the cover body 1002 and the limiting plug 1021 is H1, the dimension between the limiting plug 1021 and the top wall 1011 is H2, and the dimension of the top wall 1011 is h. When H1>H2+h is satisfied, there is a gap between the top wall 1011 and the cover body 1002, and the movable cavity 102 can adjust its size in time according to the air pressure inside itself, so that the blocked aeration mechanism 10 can promptly flush out the organic waste blocking itself.

[0075] According to some embodiments of the present application, Figure 5 , Figure 7 and Fig. 9 As shown, the limiting component 102 further includes an elastic member 1022, both ends of which are respectively connected to the cover body 1002 and the top wall 1011, and the dimension of the elastic member 1022 in the length direction of the fixing component 100 is H3, satisfying H3≤H1+h.

[0076] The elastic member 1022 may be, but is not limited to, a spring.

[0077] When H3>H1+h, in the length direction of the fixed component 100, the top wall 1011 is farther away from the cover body 1002 than the limiting plug 1021. On the one hand, when the aeration device 1 is not in working state, the movable component 101 is suspended on the elastic member 1022, and the elastic member 1022 is in a stretched state for a long time, and the elasticity will gradually weaken. On the other hand, the elastic member 1022 cannot limit the direction of movement of the movable component 101, and there is a risk that the movable component 101 deviates from the length direction of the fixed component 100 during movement.

[0078] The limiting component 102 also includes an elastic member 1022, and the two ends of the elastic member 1022 are respectively connected to the cover body 1002 and the top wall 1011. The two ends of the elastic member 1022 can respectively abut against the cover body 1002 and the top wall 1011. On the one hand, when the aeration device 1 provided by the present application is not in a working state, the elastic member 1022 can press the top wall 1011 against the limiting plug 1021, thereby reducing the risk that the movable component 101 moves on its own and causes its position to deviate from the standby state and cannot return to its original position when the operation starts; on the other hand, the larger the elastic coefficient of the elastic member 1022, the greater the elastic force exerted by the elastic member 1022 on the movable component 101, and the movable component 101 moves The greater the air pressure in the active chamber 102 required to dynamically push the elastic member 1022 to contract, the faster the rate at which the gas in the active chamber 102 passes through the connection between the first aeration port 1000 and the second aeration port 1010 when the aeration device 1 works normally. In summary, the rate at which the aeration mechanism 10 outputs gas can be adjusted by replacing elastic members 1022 with different elastic coefficients to meet the aeration requirements in different working environments; the dimension of the elastic member 1022 in the length direction of the fixed component 100 is H3. When H3≤H1+h is satisfied, the elastic member 1022 is in a contracted state and can continuously apply elastic force to the top wall 1011.

[0079] According to some embodiments of the present application, Figure 5 , Figure 7 and Fig. 9 As shown, a convex ring 1005 is provided on the surface of the cover 1002 facing the main body 1001 , and the convex ring 1005 extends into the main body 1001 and fits with the inner wall of the main body 1001 .

[0080] A seal may be provided between the protruding ring 1005 and the inner wall of the main body 1001 .

[0081] The cover body 1002 is provided with a convex ring 1005, which extends into the main body 1001 and is adapted to the inner wall of the main body 1001. On the one hand, the cooperation between the convex ring 1005 and the inner wall of the main body 1001 can increase the connection stability between the cover body 1002 and the main body 1001 and reduce the risk of the two separating on their own; on the other hand, when connecting the main body 1001 and the cover body 1002, the cooperation between the convex ring 1005 and the main body 1001 can realize the rapid positioning and connection of the main body 1001 and the cover body 1002, thereby reducing the operational difficulty when installing the main body 1001 and the cover body 1002.

[0082] According to some embodiments of the present application, Figure 7 and Fig. 9 As shown, there are plural limiting components 102 .

[0083] When the inner wall of the main body 1001 is cylindrical, the side wall 1013 that fits the inner wall of the main body 1001 is also cylindrical, and the side wall 1013 is coaxial with the inner wall of the main body 1001. The number of limiting components 102 is multiple, which can limit the rotation of the side wall 1013 of the movable component 101 relative to the inner wall of the main body 1001, thereby reducing the risk of the connection between the second aeration port 1010 and the first aeration port 1000 increasing or decreasing due to the self-rotation of the side wall 1013, which is inconsistent with the current working environment.

[0084] According to some embodiments of the present application, Figure 1 As shown, the present application provides an aeration system for inputting air into a fermentation tank 2 filled with organic waste, the aeration system comprising an air intake pump 3, an air pipe 4 and the aeration device 1 described above; the air intake pump 3 is arranged on the outside of the fermentation tank 2; one end of the air pipe 4 is connected to the air intake end of the air intake pump 3, and the other end of the air pipe 4 extends to the inside of the fermentation tank 2, the air pipe 4 is arranged close to the bottom of the fermentation tank 2, and the air pipe 4 can be covered by the organic waste in the fermentation tank 2; the aeration device 1 is arranged on the air pipe 4, and the aeration device 1 is arranged on the inside of the fermentation tank 2.

[0085] The air delivery pipe 4 mentioned in the aeration system is the same component as the pipeline mentioned above.

[0086] The gas pipe 4 can be a hose. When the air pressure inside a local area of ​​the gas pipe 4 is high, the volume of the hose in this area can expand within a certain range, thereby reducing the volume of the internal space of the gas pipe 4 in this area, reducing the air pressure inside the gas pipe 4 in this area, and reducing the risk of damage to the gas pipe 4 due to uneven pressure in various internal areas; alternatively, the material of the gas pipe 4 can be metal, which has higher strength, and the gas pipe 4 is not easily damaged by the higher air pressure inside itself.

[0087] The aeration system includes an air intake pump 3, an air pipe 4 and the aeration device 1 mentioned above. The air intake pump 3 inputs air into the air pipe 4, and the air is released into the fermentation tank 2 through the aeration device 1 on the air pipe 4 to meet the fermentation needs of organic waste. Under normal circumstances, when air flows in a curved pipe, the flow rate of the air at the bend of the pipe will slow down. The air pipe 4 is arranged straight in the fermentation tank 2, so that the air entering the air pipe 4 can continue to flow at a high speed, thereby reaching various parts of the air pipe 4 more quickly, reducing the risk of uneven air pressure in various parts of the air pipe 4 causing excessive air pressure in local areas to damage the air pipe 4.

[0088] In the following embodiments, a plurality of relay pumps are evenly arranged along the extension direction of the gas pipeline 4 , and the relay pumps can accelerate the flow rate of the gas at various locations in the gas pipeline 4 , so that the gas can reach various locations of the gas pipeline 4 and the aeration device 1 more quickly.

[0089] According to some embodiments of the present application, Figure 1 As shown, there are multiple air intake pumps 3 and multiple air pipes 4, and the multiple air intake pumps 3 correspond one to one with the multiple air pipes 4. The air pipes 4 extend along a first direction X in the fermentation tank 2, and the multiple air pipes 4 are arranged in the fermentation tank 2 along a second direction Y. The multiple aeration mechanisms 10 of the multiple air pipes 4 are evenly distributed in the fermentation tank 2 in an array, and the first direction X is perpendicular to the second direction Y.

[0090] The X direction shown in the figure is a first direction.

[0091] The Y direction shown in the figure is the second direction.

[0092] The air pipe 4 extends along the first direction X in the fermentation tank 2, and multiple air pipes 4 are arranged in the fermentation tank 2 along the second direction Y. The multiple aeration mechanisms 10 of the multiple air pipes 4 are evenly distributed in the fermentation tank 2 in an array, so that organic waste in each area of ​​the fermentation tank 2 can have corresponding aeration mechanisms 10 to input air, thereby improving the overall fermentation efficiency of the organic waste in the fermentation tank 2.

[0093] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
