Description

Technical Field

[0001] The utility model relates to the technical field of aeration pipelines, in particular to an aeration device used in solid waste fermentation equipment. Background Art

[0002] Solid waste fermentation equipment is a mechanical device specially used to treat solid waste, especially organic solid waste. This equipment is mainly used to convert agricultural waste (such as livestock and poultry manure), kitchen waste, food processing residues, garden waste and other solid waste containing organic matter into valuable products such as fertilizer, biogas or biomass energy through aerobic or anaerobic fermentation processes.

[0003] The aeration device plays a key role in solid waste fermentation equipment, especially for aerobic fermentation processes. The main principle is that the aeration device is connected to an external air supply device to force air into the materials in the fermentation tank or fermentation tank. In the aerobic fermentation process, oxygen is an essential component for microorganisms to perform aerobic respiration. The aeration device disperses the air into fine bubbles so that it can be more effectively dissolved in the wet environment of the waste.

[0004] When bubbles rise in the fermentation material, oxygen can diffuse rapidly and contact with microorganisms, providing the microorganisms with what they need for biological oxidation reactions. This process not only accelerates the decomposition rate of organic matter, but also promotes the proliferation and metabolic activity of microbial populations, ultimately achieving effective conversion of organic waste, generating carbon dioxide, water, and valuable by-products (such as fertilizer or biomass energy). At the same time, aeration also helps mix materials, ensuring that microorganisms in various parts of the fermentation tank have sufficient oxygen supply, maintaining the stable operation of the entire fermentation system.

[0005] However, the aeration amount of the current aeration device varies depending on the distance from the air source, that is, the aeration is uneven, and thus the requirement for aeration uniformity in the solid waste fermentation process cannot be met.

[0006] Utility model patent CN219413833U discloses "a perforated aeration pipe device with holes and leaks", which rotates the handle to drive the screw to rotate, so that the screw pushes the arc bar to move, so that the arc bar pushes the support rod to move, so that the support rod controls the movement of the baffle, so that the baffle moves, and at the same time the baffle compresses the spring so that the baffle can cover the corresponding holes on the mesh plate, and the aeration amount of the mesh plate can be adjusted at this time. However, this aeration device requires manual adjustment of the aeration amount, which wastes manpower and material resources, and it is not easy to control the uniformity of the aeration amount.

[0007] Therefore, there is an urgent need for an aeration device that can automatically adjust the aeration volume so that the aeration volume can be more uniform regardless of the distance from the air source. Utility Model Content

[0021] Preferably, the aeration components on the same branch pipe have the same structure and orientation.

[0022] (III) Beneficial effects

[0023] The beneficial effects of the utility model are:

[0024] 1. The utility model is an aeration device for solid waste fermentation equipment. By setting a pipe cover and an elastic member, when the air supply equipment supplies air to the aeration assembly, wind enters from the air inlet and enters from the air inlet pipe to each branch pipe. Since the aeration pipe is located at different positions on each branch pipe, the wind speed in the aeration pipe at each position of the branch pipe is different, that is, the aeration volume of each aeration pipe is different. Through the cooperation of the pipe cover and the elastic member, after the wind enters the aeration pipe, due to the different air volumes of each aeration pipe and the different expansion and contraction amounts of the elastic member, the pipe cover is driven to move along the axis of the aeration pipe by different distances, so that the pipe cover blocks The number of aeration holes on the aeration pipe is different, that is, the aeration amount of each aeration pipe is different. The aeration pipe close to the wind source has a relatively large wind impact force, a large aeration amount, and a large extension of the elastic member, so that the pipe cover blocks a large number of aeration holes, that is, the number of exposed aeration holes is relatively small; on the contrary, the aeration pipe far from the wind source has a reduced wind volume, a relatively small wind impact force, a small aeration amount, and a small extension of the elastic member, so that the pipe cover blocks a small number of aeration holes, that is, the number of exposed aeration holes is relatively large, thereby realizing automatic adjustment of the aeration amount of the aeration pipe by the aeration component, so that the aeration amount of the aeration pipe at different positions is uniform.

[0025] 2. The utility model is an aeration device used in solid waste fermentation equipment. By setting a wind shield, a connecting rod and a shielding ring, the wind shield can fit with one end of the aeration pipe. When wind enters the aeration pipe for aeration, due to the strong wind force, a part of the wind impacts the wind shield, so that the wind shield drives the connecting rod and the shielding ring to move along the axis of the aeration pipe, and the elastic member limits the moving distance of the shielding ring, and also gives the wind shield to the direction of the aeration pipe. The rebound force, to prevent the wind shield, the connecting rod and the shielding ring from moving too far away from the aeration pipe; the shielding ring shields the aeration holes to achieve the effect of changing the number of aeration holes and changing the aeration volume of the aeration pipe. By setting a plurality of connecting rods, the connection between the shielding ring and the wind shield can be strengthened, so that the stability of the pipe cover is stronger.

[0026] 3. The utility model is an aeration device used in solid waste fermentation equipment. By setting a limit block on the outer wall of the aeration tube, it can limit the shielding ring to prevent the impact force of the wind from being too large and exceeding the stretching range of the elastic member, causing the elastic member to break, and then causing damage to the device; and by setting the position of the limit block between two adjacent rows of aeration holes, it can always ensure that there are multiple rows of aeration holes that are not blocked, avoiding the shielding ring from blocking all the aeration holes, resulting in the aeration tube being unable to be aerated. By providing a plurality of limit blocks and forming a circumferential array around the axis of the aeration tube, the stability of the limit block's limiting effect on the shielding ring can be improved. At the same time, when multiple limit blocks limit the shielding ring, the force applied by the shielding ring to the limit block can also be more uniform, avoiding the shielding ring from being offset, causing the shielding ring to be deformed, etc.

[0027] 4. The aeration device used in the solid waste fermentation equipment of the utility model can prevent waste from entering the aeration pipe from the aeration hole by setting an anti-blocking net. What's more, it may cause the aeration pipe to be blocked, thereby making the aeration pipe unable to be aerated.

[0028] 5. The utility model is an aeration device used in solid waste fermentation equipment. By setting the anti-blocking net as a mesh structure, it has higher stability, greater strength, wear resistance, and long service life. Moreover, the mesh structure can better block waste and prevent waste from clogging the aeration holes.

[0029] 6. The utility model is an aeration device used in solid waste fermentation equipment. By setting the anti-blocking net in a vertical rod shape, it has the advantages of high strength, high bearing capacity and high porosity. Moreover, the vertical rod-shaped anti-blocking net can also improve the strength of the connecting rod, which can share the force between the connecting rod and the wind shield and the shielding ring.

[0030] 7. The utility model is an aeration device for solid waste fermentation equipment. By setting the elastic member as a double-hook spring, it has the advantages of firm connection, easy installation, bidirectional load, flexible adjustment and space saving. By setting the first mounting member and the second mounting member, the two ends of the double-hook spring can be hooked on the first mounting member and the second mounting member respectively, so that the double-hook spring can be detachably installed in the aeration pipe, thereby realizing elastic support for the pipe cover. By making the structure and orientation of the aeration components on the same branch pipe the same, the aeration volume of the aeration pipe at each position is uniform.

On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0039] Embodiment 1

[0040] like Figure 1-5 As shown, an aeration device 4 used in a solid waste fermentation device of the present embodiment includes an air inlet pipe 1, an air supply device connected to and communicated with the air inlet 1a of the air inlet pipe 1, and a plurality of parallel branch pipes 2 communicated with the air outlet of the air inlet pipe 1, one end of the branch pipe 2 away from the air inlet pipe 1 is closed or a plugging cap 3 is provided at the end of the branch pipe 2 away from the air inlet pipe 1 to close each branch pipe 2, and a plurality of aeration components 4 are arranged on each branch pipe 2 along the axial direction at intervals.

[0041] Specifically, the aeration assembly 4 includes an aeration tube 41 connected and communicated with the branch tube 2, a tube cover 44 movably sleeved on the outer wall of the aeration tube 41, and an elastic member 43 placed in the aeration tube 41; a plurality of aeration holes 42 are provided on the outer wall of the aeration tube 41 in a matrix, that is, a plurality of aeration holes 42 are evenly distributed on a number of lines parallel to the axis of the aeration tube 41, and these lines are evenly distributed on the circumferential outer wall of the aeration tube 41, thereby forming a matrix-like arrangement; the elastic member 43 elastically supports the tube cover 44, and the elastic member 43 can automatically expand and contract according to the air volume in the branch tube 2 to drive the tube cover 44 to move along the axis of the aeration tube 41, thereby covering a corresponding number of aeration holes 42 to change the aeration volume of the aeration tube 41. It should be noted that the corresponding number of aeration holes 42 here is not the number calculated by the calculation formula, but the number of aeration holes 42 covered by the tube cover 44 on the aeration tube 41 at different positions is different. By providing the pipe cover 44 and the elastic member 43, when the air supply device performs air supply aeration on the aeration assembly 4, the wind enters from the air inlet 1a, and enters from the air inlet pipe 1 to each branch pipe 2. Since the aeration pipe 41 is located at different positions on each branch pipe 2, the wind speed in the aeration pipe 41 at each position of the branch pipe 2 is different, that is, the aeration amount of each aeration pipe 41 is different. Through the cooperation of the pipe cover 44 and the elastic member 43, after the wind enters the aeration pipe 41, due to the different air volumes of each aeration pipe 41, the expansion and contraction amounts of the elastic member 43 are different, thereby driving the pipe cover 44 to move along the axis of the aeration pipe 41 by different distances, so that the pipe cover 44 blocks the aeration holes 42 on the aeration pipe 41 The number of aeration holes 42 is different, that is, the aeration amount of each aeration tube 41 is different. The aeration tube 41 close to the wind source has a relatively large impact force of the wind, a large aeration amount, and a large extension of the elastic member 43, so that the number of aeration holes 42 blocked by the tube cover 44 is large, that is, the number of exposed aeration holes 42 is relatively small; on the contrary, the aeration tube 41 far from the wind source has a reduced wind volume, a relatively small impact force of the wind, a small aeration amount, and a small extension of the elastic member 43, so that the number of aeration holes 42 blocked by the tube cover 44 is small, that is, the number of exposed aeration holes 42 is relatively large, so that the aeration assembly 4 automatically adjusts the aeration amount of the aeration tube 41, so that the aeration amount of the aeration tube 41 at different positions is uniform. Preferably, the structure and orientation of the aeration assembly 4 on the same branch pipe 2 are the same, so that the aeration amount of the aeration tube 41 at each position is uniform.

[0042] Furthermore, if Figure 2-Figure 3 and Figure 5As shown, the pipe cover 44 includes a wind shield 441, a connecting rod 442 and a shielding ring 443; wherein, the two ends of the connecting rod 442 are respectively connected to the opposite outer walls of the wind shield 441 and the shielding ring 443 and the two ends of the connecting rod 442 are respectively located at the outer edges of the wind shield 441 and the shielding ring 443, and there is a gap between the connecting rod 442 and the aeration pipe 41; the outer wall where the wind shield 441 and the connecting rod 442 are connected can fit with the end of the aeration pipe 41 away from the branch pipe 2, the shielding ring 443 is located at the end of the aeration pipe 41 close to the branch pipe 2 and the inner wall of the shielding ring 443 is always in contact with the outer wall of the aeration pipe 41, so that the shielding ring 443 can shield the aeration hole 42. By providing the wind shield 441, the connecting rod 442 and the shielding ring 443, the wind shield 441 can be fitted with one end of the aeration tube 41, so that when wind enters the aeration tube 41 for aeration, due to the strong wind force, a part of the wind impacts the wind shield 441, so that the wind shield 441 drives the connecting rod 442 and the shielding ring 443 to move along the axis of the aeration tube 41, and the elastic member 43 limits the moving distance of the shielding ring 443, and also gives the wind shield 441 a rebound force toward the aeration tube 41, so as to prevent the wind shield 441, the connecting rod 442 and the shielding ring 443 from moving too far and leaving the aeration tube 41; the shielding ring 443 shields the aeration holes 42, so as to achieve the effect of changing the number of aeration holes 42 and changing the aeration amount of the aeration tube 41. Preferably, a plurality of connecting rods 442 are provided and the plurality of connecting rods 442 are circumferentially arranged around the axis of the aeration tube 41, which can enhance the connection between the shielding ring 443 and the wind shield 441, thereby making the tube cover 44 more stable. Each connecting rod 442 is located between two adjacent rows of aeration holes 42 along the axis of the aeration tube 41 to avoid the connecting rod 442 blocking the aeration hole 42 and affecting the aeration amount of the aeration hole 42.

[0043] Furthermore, the elastic member 43 is a double-hook spring, which has the advantages of firm connection, easy installation, bidirectional load, flexible adjustment and space saving; a first mounting member 5 is installed on the inner wall of the connection point between the aeration pipe 41 and the branch pipe 2, and a second mounting member 6 is installed on the side wall of the wind shield 441 facing the branch pipe 2. The two ends of the double-hook spring are respectively hooked on the first mounting member 5 and the second mounting member 6, so that the double-hook spring can be detachably installed in the aeration pipe 41, thereby realizing elastic support for the pipe cover 44.

[0044] Furthermore, a limit block 45 is installed on the outer wall of the aeration tube 41, which can limit the blocking ring 443, prevent the impact force of the wind from being too large, exceeding the stretching range of the elastic member 43, causing the elastic member 43 to break, and then causing damage to the device; the limit block 45 is located between two adjacent rows of aeration holes 42 arranged circumferentially around the axis of the aeration tube 41, which can ensure that there are always multiple rows of aeration holes 42 that are not blocked, and prevent the blocking ring 443 from blocking all the aeration holes 42, resulting in the aeration tube 41 being unable to be aerated. Preferably, the limit block 45 is provided with a plurality of limit blocks 45 and the plurality of limit blocks 45 are arranged circumferentially around the axis of the aeration tube 41, which can improve the stability of the limit block 45 on the blocking ring 443. At the same time, when the plurality of limit blocks 45 limit the blocking ring 443, the force applied by the blocking ring 443 to the limit block 45 can also be more uniform, avoiding the displacement of the blocking ring 443, causing the deformation of the blocking ring 443, etc.

[0045] Furthermore, the pipe cover 44 also includes an anti-blocking net 444; the two ends of the anti-blocking net 444 are respectively connected to the outer walls of the opposite sides of the wind shield 441 and the shielding ring 443 and the anti-blocking net 444 is located at multiple aeration holes 42, which can prevent waste from entering the aeration pipe 41 from the aeration holes 42. What's more, it may cause the aeration pipe 41 to be blocked, thereby causing the aeration pipe 41 to be unable to be aerated.

[0046] Preferably, the anti-blocking net 444 is a mesh structure and is located between the plurality of connecting rods 442 and the aeration tube 41 or between every two adjacent connecting rods 442, and one side wall of the anti-blocking net 444 is in contact with the outer wall of the aeration tube 41; the plurality of connecting rods 442 located at the limit block 45 can pass through the limit block 45, and the anti-blocking net 444 located at the limit block 45 can bypass the limit block 45 to avoid interference between the anti-blocking net 444 and the limit block 45. By setting the anti-blocking net 444 as a mesh structure, it has higher stability, greater strength, wear resistance, and longer service life. Moreover, the mesh structure can better block waste materials and prevent waste materials from clogging the aeration holes 42.

[0047] Through the above structure, the working principle of an aeration device 4 used in a solid waste fermentation device in this embodiment is:

[0048] like Figure 1 As shown, the device is assembled and installed on each branch pipe 2 with equal intervals and the same direction, and then the air supply device is connected and communicated with the air inlet 1a of the air intake pipe 1. The air supply device here can be an air supply device such as a blower; the air supply device is driven to supply air to the air intake pipe 1, and the air enters the multiple branch pipes 2 one by one from the air intake pipe 1.

[0049] The air volume of the aeration pipe 41 close to the wind source is relatively large, and the impact force generated by the wind is relatively large. The wind thus has a relatively large impact force on the wind shield 441, causing the wind shield 441 to move a long distance in the direction away from the aeration pipe 41. Due to the connection of the connecting rod 442, the shielding ring 443 moves with the movement of the wind shield 441, thereby shielding the aeration hole 42, thereby changing the aeration volume of the aeration pipe 41 close to the wind source; and the air volume of the aeration pipe 41 far from the wind source is divided by the aeration pipe 41 close to the wind source. Therefore, when the wind flows through the aeration pipe 41 that is farther away, the wind volume is relatively reduced, thereby reducing the wind volume in the aeration pipe 41 that is farther away from the wind source, and the impact force of the wind is relatively reduced, which makes the impact force of the wind on the wind shield 441 reduced, thereby reducing the distance that the wind shield 441 moves in the direction away from the aeration pipe 41. Alternatively, the impact force of the wind is too small, causing the wind shield 441 to remain motionless, thereby making the aeration volume of the aeration pipe 41 that is farther away from the wind source relatively large, so as to even out the aeration volume of each aeration pipe 41.

[0050] Embodiment 2

[0051] Different from the first embodiment, Figure 4 As shown, the anti-blocking net 444 in this embodiment includes a plurality of vertical rods 4441 and the plurality of vertical rods 4441 are circumferentially arrayed around the axis of the aeration tube 41; the plurality of vertical rods 4441 are located between the aeration tube 41 and the plurality of connecting rods 442 or each portion of the plurality of vertical rods 4441 is located between every two adjacent connecting rods 442; the outer walls of the plurality of vertical rods 4441 are in contact with the outer wall of the aeration tube 41 and the plurality of vertical rods 4441 and the connecting rods 442 located at the stop block 45 can pass through the stop block 45. By setting the anti-blocking net 444 in the shape of the vertical rods 4441, it has the advantages of high strength, high bearing capacity and high permeability, and the anti-blocking net 444 in the shape of the vertical rods 4441 can also improve the strength of the connecting rod 442, and can share the force between the connecting rod 442 and the wind shield 441 and the shielding ring 443.
