Description

Technical Field

[0001] This invention relates to the field of composting technology, specifically to an auxiliary aeration device for composting brewing waste and its usage method. Background Technology

[0002] Composting is the process of producing organic fertilizer using microorganisms. The waste residue generated during the brewing process still contains a large amount of organic matter. Directly discarding it would waste resources and pollute the environment. Therefore, the waste residue can be further fermented through composting to produce organic fertilizer.

[0003] Currently, when producing organic fertilizer from large amounts of waste residue, it is difficult to turn the compost. In order to ensure a normal aerobic fermentation process, a large amount of air needs to be introduced into the organic fertilizer to compensate for the poor air circulation caused by the difficulty of turning the compost and to ensure a normal fermentation process.

[0004] The current ventilation method is pipe ventilation. When the waste residue is piled up, after a certain period of time, several sets of holes are made in the compost pile by manual cutting. External air enters the compost pile through the holes to replenish the air. However, as the compost pile deforms during the continuous fermentation process, the ventilation holes will shrink and become smaller, and cannot be retained for a long time. Therefore, workers need to make holes multiple times, which is a complicated process and labor-intensive.

[0005] To address these issues, we propose an auxiliary aeration device for brewing waste composting and its usage method. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this invention provides an auxiliary aeration device and method for using brewing waste compost. This device can solve the problem that as the compost pile deforms during the fermentation process, the ventilation holes will continuously shrink and become smaller, making it impossible to retain them for a long time. Therefore, it requires workers to open the holes multiple times, which is a complicated process and labor-intensive.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an auxiliary aeration device for composting brewing waste and a method of use, comprising several sets of aeration conduits, two aeration conduits being connected end to end by a flexible connection assembly to form a connected air channel, the end of the bottom aeration conduit being threadedly connected to an air outlet, and the end of the top aeration conduit being connected to an external air supply device.

[0011] As a preferred embodiment of the present invention, the protective sleeve includes a sleeve body, a spring groove and a spring. The sleeve body is sleeved on the outside of the flexible connection assembly and nested with the outside of the two sets of ventilation ducts. Several sets of spring grooves are opened on both ends of the inner wall of the sleeve body, and a spring is provided inside each set of spring grooves.

[0012] As a preferred embodiment of the present invention, a limiting ring is provided on the outer surface of the end of the ventilation duct to cooperate with the sleeve body, and the diameter of the limiting ring is larger than the diameter of the sleeve body.

[0014] As a preferred embodiment of the present invention, a sealing gasket is fitted at the threaded connection of the air outlet end.

[0015] The present invention also provides a technical solution, a brewing waste composting auxiliary aeration device and its usage method, the specific steps of which are as follows:

[0016] A. Connect the ventilation duct and flexible connection assembly;

[0017] A1. Prepare several sets of ventilation tubing and flexible connection components;

[0023] C. Install a limiting ring on the outer surface of the end of the ventilation duct that mates with the sleeve body to restrict the range of motion of the sleeve body;

[0024] D. Connect the ventilation tube and the air outlet, and prepare several sets of air outlets;

[0025] D1. Place sealing gaskets on the threaded connection ports at both ends of the air outlet.

[0026] D2. Connect the upper end of the outlet end with the sealing gasket to the end of the bottom air duct through the threaded connection port.

[0037] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0038] 1. In this invention, the ventilation duct and the flexible connection assembly can form a fixed ventilation channel, which will not be affected by compost deformation, thus avoiding the problem that manual openings will disappear with the composting process and reducing labor costs.

[0039] 2. In this invention, the flexible connection component can provide a flexible connection between ventilation ducts of different depths.

[0049] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0050] Example 1

[0051] like Figure 1-3 As shown in the figure, this embodiment proposes an auxiliary aeration device for brewing waste composting, including several sets of aeration pipes 1. The two ends of the aeration pipes 1 are connected by a flexible connecting component 2 to form a connected air guiding channel. The end of the bottom aeration pipe 1 is threadedly connected to an air outlet 4, and the end of the top aeration pipe 1 is connected to an external air supply device. The external air source continuously supplies air to the air outlet 4 buried in the composting raw material through the air guiding channel formed by the aeration pipes 1 and the flexible connecting component 2.

[0052] The ventilation duct 1 has internal threads at both ends. The ventilation duct 1 is connected to the flexible connection component 2 by threads. The flexible connection component 2 includes a rubber hose 21 and two sets of connecting joints 22. The two sets of connecting joints 22 are fixed to the ends of the rubber hose 21 respectively. The surface of the connecting joints 22 has external threads. The connecting joints 22 are threaded to the ventilation duct 1. The flexible connection component 2 can provide flexible connection between ventilation ducts 1 at different depths. Ventilation ducts 1 at different burial depths can be displaced to a certain extent with the shrinkage of the material pile, avoiding the problem that the one-piece ventilation duct 1 is easily squeezed and bent. At the same time, through the splicing design, it can be adjusted according to the actual use depth.

[0053] A protective sleeve 3 is fitted over the outside of the flexible connection component 2. Both ends of the protective sleeve 3 are nested with the outside of the two sets of ventilation ducts 1. Space is left at the nesting point between the protective sleeve 3 and the ventilation ducts 1 for the ventilation ducts 1 to move, so that the ventilation ducts 1 of different depths can be displaced to a certain extent as the material is compressed. At the same time, the protective sleeve 3 protects the flexible connection component 2. The protective sleeve 3 includes a sleeve body 31, a spring groove 32 and a spring 33. The sleeve body 31 is fitted over the outside of the flexible connection component 2 and nested with the outside of the two sets of ventilation ducts 1. Several sets of spring grooves 32 are opened on both ends of the inner wall of the sleeve body 31. A spring 33 is provided inside each set of spring grooves 32. The spring 33 can maintain the distance between the sleeve body 31 and the flexible connection component 2 by contacting the outer wall of the ventilation duct 1. This prevents one side of the sleeve body 31 from tilting excessively to one side under the push of the material, so that the compost material can enter the inside of the sleeve body 31 through the gap caused by the tilt.

[0054] A limiting ring 11 that mates with the sleeve body 31 is provided on the outer surface of the end of the ventilation duct 1. The diameter of the limiting ring 11 is larger than the diameter of the sleeve body 31. The presence of the limiting ring 11 restricts the range of motion of the protective sleeve 3. The protective sleeve 3 can only move between the two sets of limiting rings 11 in opposite directions of the two sets of ventilation ducts 1. While leaving space for the protective sleeve 3 to move, it also prevents the protective sleeve 3 from slipping off the set position of the flexible connection component 2, ensuring the normal protection of the flexible connection component 2 by the protective sleeve 3.

[0055] Both the upper and lower ends of the air outlet 4 are provided with threaded connection ports for connecting to the ventilation duct 1. By setting interfaces at both the upper and lower ends, multiple sets of air outlet 4 can be combined to better adapt to different compost depths. Several gas distribution rods 5 are inserted into the outer surface of the air outlet 4. The gas distribution rods 5 can better distribute and disperse the gas entering the air outlet 4, expanding the airflow delivery area. A sealing gasket 6 is fitted at the threaded connection port of the air outlet 4. When the ventilation duct 1 is threadedly connected to the air outlet 4, it will come into contact with the sealing gasket 6. The sealing gasket 6 seals the connection by deformation, preventing the wastewater generated during fermentation from entering. At the same time, the elastic force generated by the deformation applies a reaction force to the ventilation duct 1, so that the threaded connection between the ventilation duct 1 and the air outlet 4 always maintains a tight engagement, preventing the connection from loosening.

[0056] Example 2

[0057] Multiple sets of ventilation ducts 1 connected by flexible connector assembly 2 can be used independently without the outlet end 4, such as Figure 4 As shown, a brewing waste composting auxiliary aeration device includes several sets of aeration ducts 1. The two ends of the aeration ducts 1 are connected by a flexible connecting component 2 to form a connected air guiding channel. The surface of the aeration ducts 1 is opened with several sets of through holes to form a vertical air guiding channel.

[0058] Example 3

[0059] like Figure 5 As shown, the two ventilation ducts 1 are connected end to end by a flexible connecting component 2 to form a connected air channel. The end of the bottom ventilation duct 1 is threadedly connected to an air outlet 4. The bottom of the air outlet 4 is further threadedly connected to a new set of air channels. The bottom of the new set of air channels is also provided with an air outlet 4.

[0060] In the specific use of this invention, the specific steps are as follows: connect the ventilation duct 1 and the flexible connection component 2, prepare several sets of ventilation duct 1 and flexible connection component 2, and connect several sets of ventilation duct 1 through rubber hoses 21 with connecting joints 22 at both ends to form a ventilation channel;

[0061] Connect the flexible connection component 2 and the protective sleeve 3, prepare several sets of protective sleeves 3, fit the sleeve body 31 onto the outside of the flexible connection component 2, and at the same time connect the springs 33 in several sets of spring grooves 32 at both ends of the inner wall of the sleeve body 31 to the outer wall of the ventilation duct 1 to form a space for the ventilation duct 1 to move.

[0062] A limiting ring 11 that mates with the sleeve body 31 is installed on the outer surface of the end of the ventilation duct 1 to limit the range of motion of the sleeve body 31.

[0063] Connect the ventilation duct 1 and the air outlet 4. Prepare several sets of air outlets 4. First, put sealing gaskets 6 on the threaded connection ports at the upper and lower ends of the air outlet 4. Then, connect the upper end of the air outlet 4 with the sealing gaskets 6 to the end of the bottom ventilation duct 1 through the threaded connection port. Finally, insert several sets of air rods 5 on the outer surface of the air outlet 4.

[0064] Prepare for ventilation connection. Check the connections of ventilation duct 1, flexible connection assembly 2, protective sleeve 3, and outlet end 4. Bury the connected outlet end 4 inside the compost material. Connect the end of the top ventilation duct 1 to the external air supply device to supply air. The external air source continuously supplies air to the outlet end 4 buried in the compost material through the air guide channel formed by ventilation duct 1 and flexible connection assembly 2. The gas entering the outlet end 4 is distributed and dispersed within the compost material through several component air rods 5, completing the ventilation connection.

[0065] When aerating a small compost pile, prepare several sets of aeration pipes 1 with through holes on their surfaces. The aeration pipes 1 are connected end to end by flexible connecting components 2 to form a continuous aeration channel, thus constituting a vertical aeration capacity.

[0066] When aerating a large compost pile, the end of the bottom aeration duct 1 is threadedly connected to an air outlet 4. The bottom of the air outlet 4 is further threadedly connected to a new set of aeration channels. The bottom of the new set of aeration channels is also equipped with an air outlet 4, forming a multi-level aeration capacity.

[0067] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
