Description

Technical Field

[0001] This utility model mainly relates to the field of aeration equipment technology, specifically an aeration pipe for composting. Background Technology

[0002] In the composting process, the activity of microorganisms directly affects composting efficiency and maturation quality, while a sufficient and uniform oxygen supply is a key condition for maintaining microbial activity. As the core component for transporting oxygen in the composting system, the structural design of the aeration pipe directly relates to the uniformity of oxygen supply, ease of installation, and long-term stability.

[0003] Existing aeration pipes for composting are generally conventional circular pipes. During installation, they are prone to rolling, which can cause the aeration holes to deflect and affect the aeration effect. In addition, the existing aeration pipes have complicated connection methods. Traditional aeration pipes often use flange connections or glue bonding, which require professional tools and a long operation time during installation. Furthermore, they are difficult to maintain and disassemble later, making them unsuitable for the flexible adjustment needs of composting sites. The inconvenience of installation and disassembly affects the efficiency of operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an aeration pipe for composting, achieved through the following technical solution:

[0005] An aeration pipe for composting includes an aeration pipe with quick-connect fittings screwed to both ends, and a plurality of evenly distributed aeration holes on the top surface of the aeration pipe.

[0006] Furthermore, the quick-connector includes:

[0007] A connecting pipe, wherein the connecting pipe is disposed outside the aeration pipe;

[0008] External threaded connectors are rotatably installed at both ends of the connecting pipe, and internal threads are provided at both ends of the inner wall of the aeration pipe. The corresponding external threaded connectors are threadedly installed at both ends of the aeration pipe.

[0009] A sealing connection assembly is provided at the connection between the connecting pipe and the external threaded joint.

[0010] Furthermore, the sealing connection assembly includes:

[0011] The connecting plate is integrally fixedly installed on the periphery of both ends of the connecting pipe. An annular limiting groove is opened on one side inside the external threaded joint. The connecting plate is located in the corresponding annular limiting groove and slides in cooperation with it.

[0012] A sealing ring is provided between the external threaded joint and the connecting pipe.

[0013] Furthermore, a first groove is provided on one side of the inner wall of the external threaded connector, and a second groove is provided on both sides of the outer periphery of the connecting pipe, which is opposite to the first groove. A sealing ring is installed between the first groove and the opposite second groove.

[0014] Furthermore, both the first and second slots are trapezoidal structures, and the inner and outer rings of the sealing ring are matched with the first and second slots.

[0015] Furthermore, it also includes a cap that can be threadedly connected to an external threaded connector, and the cap has a sealing gasket inside.

[0016] Furthermore, a hexagonal mounting head is integrally fixedly installed on the outer end of the cover.

[0017] Compared with the existing technology, the beneficial effects of this utility model are:

[0018] 1. The aeration pipe adopts a regular hexagonal cross-section design, which can be stably placed on the ground during installation, avoiding the aeration holes from shifting due to rolling, and ensuring uniform gas discharge; the evenly distributed aeration holes make the gas distribution in the composting area more balanced, effectively improving oxygen supply efficiency, promoting the uniformity and efficiency of the composting fermentation process, and providing a stable environment for microbial activity.

[0019] 2. The quick-connect coupling uses external threads to engage with the internal threads of the aeration pipe, enabling rapid assembly and disassembly. The annular limiting groove and connecting plate design in the sealing connection assembly restricts axial displacement while allowing the external threaded connector to rotate freely, preventing the connection from disengaging. The matching structure of the trapezoidal groove and the sealing ring enhances the sealing effect through lateral support, effectively preventing gas leakage, ensuring oxygen supply efficiency, and simplifying the maintenance process.

[0020] 3. The threaded connection design of the cap and the external threaded connector, together with the sealing gasket, achieves a reliable seal on the unused port to prevent gas leakage; the hexagonal mounting head makes it easy to tighten or loosen the cap with tools, improving operational efficiency; the modular structure supports flexible expansion or independent use of the aeration pipe, adapting to the needs of different composting scenarios, while reducing installation and maintenance costs.

Detailed Implementation

[0027] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0028] Example: An aeration pipe for composting

[0029] like Figure 1-5 As shown, an aeration pipe for composting has the following specific structure:

[0030] The aeration pipe 10 has quick-connect fittings 20 screwed to both ends. The top surface of the aeration pipe 10 has several evenly distributed aeration holes 101. The cross-section of the aeration pipe (10) is a regular hexagonal structure.

[0031] The working principle described above is as follows:

[0032] As the core aeration component, the aeration pipe 10 transmits external gas through its internal channels to the aeration holes 101 on the top surface, and then evenly discharges it into the composting environment from the aeration holes 101. The quick-connect fittings 20 at both ends can be quickly connected to external pipelines or other aeration pipes to achieve rapid construction of the gas passage. Furthermore, the hexagonal structure of the aeration pipe 10 can improve the stability of the aeration pipe 10 during installation, ensuring that it is placed stably on the ground and will not roll around, causing the aeration holes 101 to shift.

[0033] The evenly distributed aeration holes 101 ensure uniform gas distribution in the composting area and improve the oxygen supply effect of composting; the screw connection design of the quick connector 20 simplifies the installation and disassembly process and improves the assembly efficiency of the aeration pipe.

[0034] The quick-connector 20 includes:

[0035] Connecting pipe 201, wherein the connecting pipe 201 is disposed outside the aeration pipe 10;

[0036] External threaded connector 202, the two ends of the connecting pipe 201 are respectively rotatably installed with external threaded connector 202, the two ends of the inner wall of the aeration pipe 10 are respectively provided with internal threads, and the two ends of the aeration pipe 10 are respectively threadedly fitted with the corresponding external threaded connector 201.

[0037] A sealing connection component 30 is provided at the connection between the connecting pipe 201 and the external threaded joint 202.

[0038] The external threaded connector 202 engages with the internal thread on the inner wall of the aeration pipe 10 to achieve a fixed connection between the connecting pipe 201 and the aeration pipe 10. The connecting pipe 201, as an intermediate connector, can be connected to external pipelines through the external threaded connectors 202 at both ends. The sealing connection assembly 30 can prevent gas from leaking from the connection between the connecting pipe 201 and the external threaded connector 202. The sealing connection assembly 30 ensures the airtightness of gas transmission and avoids a decrease in oxygen supply efficiency caused by gas leakage.

[0039] The sealing connection assembly 30 includes:

[0040] Connecting plate 301, annular connecting plates 301 are integrally fixedly installed on the periphery of both ends of the connecting pipe 201, and annular limiting groove 203 is opened on one side inside the external threaded joint 202. The connecting plates 301 are respectively located in the corresponding annular limiting groove 203 and slide in cooperation with it.

[0041] A sealing ring 302 is provided between the external threaded joint 202 and the connecting pipe 201.

[0042] The connecting plates 301 at both ends of the connecting pipe 201 are embedded in the annular limiting grooves 203 of the external threaded joint 202. Without affecting the rotation of the external threaded joint 202, they restrict the axial displacement of the connecting pipe 201 and the external threaded joint 202, preventing them from separating. The sealing ring 302 fills the gap between the external threaded joint 202 and the connecting pipe 201, blocking the gas leakage path and further enhancing the sealing of the connection, reducing the risk of gas leakage.

[0043] A first groove 204 is provided on one side of the inner wall of the external threaded connector 202, and a second groove 303 is provided on both sides of the outer periphery of the connecting pipe 201, which is opposite to the first groove 204. A sealing ring 302 is installed between the first groove 204 and the opposite second groove 303. The sealing ring 302 is installed in the annular space formed by the first groove 204 and the second groove 303. When the external threaded connector 202 and the connecting pipe 201 rotate relative to each other or are subjected to external force, the first groove 204 and the second groove 303 together limit the sealing ring 302, preventing the sealing ring 302 from shifting or falling off.

[0044] Both the first slot 204 and the second slot 303 are trapezoidal structures, and the inner and outer rings of the sealing ring 302 are matched with the first slot 204 and the second slot 303. The trapezoidal first slot 204 and the second slot 303 match the inner and outer rings of the sealing ring 302. During assembly, the sealing ring 302 can naturally embed into the trapezoidal slot, and the inclined surface of the trapezoid will exert a certain squeezing effect on the sealing ring 302, making the sealing ring 302 tightly fit against the inner wall of the slot. When subjected to gas pressure, the lateral support force of the trapezoidal structure can further enhance the sealing effect of the sealing ring 302.

[0045] It also includes a cap 40, which can be threadedly connected to the external threaded connector 202, and the cap 40 has a sealing gasket 401 inside. When one end of the aeration pipe 10 does not need to be connected to an external pipeline, the cap 40 is connected to the external threaded connector 202 by threads. Under the pressure of tightening the threads, the sealing gasket 401 inside the cap 40 comes into close contact with the port of the external threaded connector 202, blocking the gas leakage channel at that port.

[0046] A hexagonal mounting head 402 is integrally fixed to the outer end of the cover 40. The hexagonal mounting head 402 is integrally fixed to the cover 40. When installing or removing the cover 40, a wrench or other tool can be used to clamp the hexagonal mounting head 402, and torque can be applied to drive the cover 40 to rotate, thereby tightening or loosening the threads of the external threaded connector 202.

[0047] In explaining this utility model, it should be noted that the terms indicating location are only for ease of description and understanding, and are not intended to limit the installation location of specific technical features. Other possible installation methods are not excluded.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
