Description

Technical Field

[0001] This utility model relates to the field of fluid transmission and control technology, specifically to a ventilation pipe structure inside a processing equipment. Background Technology

[0002] In modern industrial production, the efficient operation of processing equipment is crucial to a company's production efficiency and economic benefits. As a vital component of processing equipment, the performance of the venting pipe structure directly impacts the equipment's stable operation and working efficiency. However, most existing venting pipe structures use a single pipe for connection, a design with several shortcomings. First, the single-pipe structure is cumbersome to install, increasing the complexity and time cost of equipment assembly. Second, venting pipes may become clogged due to impurities or other reasons during use, and the existing single-pipe design lacks a convenient cleaning mechanism, requiring the processing equipment to be shut down and the venting pipe disassembled and cleaned when a blockage occurs. This not only affects the normal operation of the processing equipment but also significantly reduces the company's production efficiency. Furthermore, frequent disassembly and installation can cause wear and tear on the venting pipe and its connecting components, further shortening the equipment's lifespan. Therefore, designing a venting pipe structure that simplifies the installation process, facilitates cleaning and maintenance, and can quickly resolve blockages without affecting normal equipment operation has become an urgent technical challenge. This utility model proposes an innovative solution based on the above problems, aiming to improve the overall performance and operating efficiency of processing equipment by optimizing the venting pipe structure design. Utility Model Content

[0003] This invention addresses the problems of complex installation, inconvenient cleaning, and equipment shutdown required when a single vent pipe is blocked in existing technologies. It proposes a new vent pipe structure for processing equipment. By optimizing the vent pipe's structural design, flexible switching of gas flow and convenient maintenance are achieved, thereby significantly improving the operating efficiency and reliability of the processing equipment.

[0004] This utility model provides a ventilation pipe structure for a processing equipment, including a fixed pipe, a first connecting pipe, a second connecting pipe, ventilation fittings, and threaded end caps. The fixed pipe serves as the basic part of the entire ventilation pipe structure, used to connect other components and form the main gas flow path; the first and second connecting pipes are respectively connected to the fixed pipe, forming two independent gas flow paths; the ventilation fittings are located at both ends of the fixed pipe, used to connect with other equipment or pipelines to realize gas input or output; the threaded end caps are installed at the ends of the ventilation fittings, serving to seal and protect the internal structure, and facilitating disassembly and maintenance.

[0005] Furthermore, the vent pipe structure also includes a first fixing ring, a second fixing ring, a first piston, a second piston, a first spring, a second spring, a first limiting rod, and a second limiting rod. The first fixing ring and the second fixing ring are respectively installed on the first connecting pipe and the second connecting pipe to fix the corresponding piston assemblies; the first piston and the second piston slide within the first connecting pipe and the second connecting pipe respectively to control the flow direction and flow rate of the gas; the first spring and the second spring are respectively installed behind the first piston and the second piston to provide a restoring force to the pistons, allowing them to return to their initial positions when not subjected to external force; the first limiting rod and the second limiting rod respectively limit the movement range of the first piston and the second piston to prevent them from disengaging or exceeding their predetermined stroke.

[0006] Specifically, the vent pipe structure also includes a sleeve, a docking cylinder, an elastic retaining ball, a pressing ring, a third spring, and a limiting plate. The sleeve is mounted on the second connecting pipe to accommodate the docking cylinder and facilitate quick connection between the two. The docking cylinder cooperates with the sleeve to connect the second connecting pipe and the fixing pipe. The elastic retaining ball is installed inside the docking cylinder and engages with a groove on the inner wall of the sleeve to achieve stable locking between the docking cylinder and the sleeve. The pressing ring is installed on the outside of the docking cylinder for manual unlocking, facilitating quick disassembly and installation. The third spring is installed between the pressing ring and the docking cylinder to provide a restoring force for the pressing ring. The limiting plate restricts the movement range of the pressing ring to prevent it from dislodging.

[0007] Furthermore, the design of the first and second connecting pipes allows the two gas flow paths to be independent and switchable. When one vent pipe becomes blocked, the other vent pipe can still allow normal gas flow through the sliding action of the first or second piston. Specifically, S1: The first piston slides backward within the first connecting pipe, compressing the first spring, while the first limiting rod restricts its sliding range; S2: The second piston maintains its initial position within the second connecting pipe, with the second spring providing a restoring force; S3: By pressing the ring, the elastic retaining ball disengages from the retaining groove on the inner wall of the sleeve, separating the connecting cylinder from the sleeve, thereby achieving rapid disassembly of the second connecting pipe.

[0008] The design of the elastic ball and the slot enables rapid connection and separation of the docking cylinder and the sleeve. The specific implementation is as follows: S1: Under external force, the pressing ring moves axially along the docking cylinder, compressing the third spring; S2: Due to the movement of the pressing ring, the elastic ball retracts inward, disengaging from the slot on the inner wall of the sleeve; S3: When the external force is removed, the third spring pushes the pressing ring back to its original position, and the elastic ball pops out again and engages with the slot, completing the locking process. This design not only simplifies the disassembly and installation of the vent pipe but also improves maintenance efficiency.

[0009] Specifically, the sliding motion of the first and second pistons is precisely controlled by the restoring force of the springs. Specifically, the sliding range of the first piston within the first connecting tube is limited by a first limiting rod, ensuring that it will not dislodge or exceed its predetermined stroke due to excessive external force; the sliding range of the second piston within the second connecting tube is limited by a second limiting rod, similarly ensuring the stability of its movement. Furthermore, the elastic coefficients of the first and second springs are precisely calculated to provide sufficient restoring force while preventing the pistons from failing to slide properly due to excessive elasticity.

[0010] Furthermore, both ends of the vent fitting are equipped with threaded end caps to facilitate cleaning and maintenance of the vent fitting's interior. Specifically, S1: Unscrew the threaded end caps to expose the internal space of the vent fitting; S2: Use a cleaning tool to clean the interior of the vent fitting; S3: After cleaning, tighten the threaded end caps again to complete the seal. This design not only simplifies the cleaning process but also effectively avoids the problem of internal scale buildup caused by long-term use.

[0011] This utility model achieves the following technical effects through the above-mentioned technical solution: First, the dual-vent pipe design solves the problem of easy clogging and inconvenient cleaning of a single vent pipe in the prior art. When one vent pipe is blocked, the other vent pipe can still work normally without shutting down the processing equipment, thus significantly improving the operating efficiency of the equipment. Second, the design of the elastic ball and groove cooperation enables quick connection and separation of the connecting cylinder and the sleeve, facilitating the disassembly and cleaning of the vent pipe and further improving maintenance efficiency. Third, the design of the first piston, the second piston, and their matching springs ensures precise control of gas flow while avoiding unexpected actions caused by external interference. Finally, the reasonable layout of the components makes the overall structure more compact and suitable for the internal space constraints of various processing equipment.

[0012] In summary, this utility model provides a highly efficient, reliable, and easy-to-maintain venting pipe structure for processing equipment, which has significant industrial application value. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model provides a ventilation pipe structure for a processing equipment, the specific implementation of which is described in conjunction with the attached diagram. Figure 1 To be continued Figure 4 A detailed explanation is provided. This venting pipe structure is designed to solve the problems of complex installation, inconvenient cleaning, and equipment shutdown required when blocked in existing technologies. Through the design of dual venting pipes and the cooperation of various functional components, flexible switching of gas flow paths and convenient maintenance are achieved.

[0022] like Figure 1 As shown, the core components of the entire venting pipe structure include a fixed pipe 1, a first connecting pipe 2, a second connecting pipe 9, a vent fitting 19, and a threaded end cap 20. The fixed pipe 1 serves as the foundation of the venting pipe structure, connecting other components and forming the main gas flow path. The first connecting pipe 2 and the second connecting pipe 9 are connected to the fixed pipe 1 respectively, forming two independent gas flow paths. The vent fitting 19 is located at both ends of the fixed pipe 1, used for connecting with other equipment or pipelines to achieve gas input or output. The threaded end cap 20 is installed at the end of the vent fitting 19, serving to seal and protect the internal structure, and facilitating disassembly and maintenance. Through this design, the venting pipe structure allows the other vent to continue operating normally even if one vent is blocked, without requiring the shutdown of the processing equipment.

[0023] Furthermore, such as Figure 2As shown, the vent pipe structure also includes a first fixing ring 3, a second fixing ring 10, a first piston 4, a second piston 11, a first spring 5, a second spring 12, a first limiting rod 6, and a second limiting rod 13. The first fixing ring 3 and the second fixing ring 10 are respectively installed on the first connecting pipe 2 and the second connecting pipe 9 to fix the corresponding piston assemblies. The first piston 4 and the second piston 11 slide within the first connecting pipe 2 and the second connecting pipe 9, respectively, to control the flow direction and flow rate of the gas. The first spring 5 and the second spring 12 are respectively installed behind the first piston 4 and the second piston 11 to provide a restoring force to the pistons, allowing them to return to their initial positions when no external force is applied. The first limiting rod 6 and the second limiting rod 13 respectively limit the movement range of the first piston 4 and the second piston 11, preventing them from dislodging or exceeding their predetermined stroke. This design ensures precise control of the gas flow while avoiding unexpected actions caused by external interference.

[0024] In particular, such as Figure 3 As shown, the vent pipe structure also includes a sleeve 7, a docking cylinder 8, an elastic retaining ball 14, a pressing ring 16, a third spring 17, and a limiting plate 18. The sleeve 7 is installed on the second connecting pipe 9 to accommodate the docking cylinder 8 and facilitate quick connection between the two. The docking cylinder 8 cooperates with the sleeve 7 to connect the second connecting pipe 9 to the fixing pipe 1. The elastic retaining ball 14 is installed inside the docking cylinder 8 and cooperates with the retaining groove 15 on the inner wall of the sleeve 7 to achieve stable locking between the docking cylinder 8 and the sleeve 7. The pressing ring 16 is installed on the outside of the docking cylinder 8 for manual unlocking, facilitating quick disassembly and installation. The third spring 17 is installed between the pressing ring 16 and the docking cylinder 8 to provide a restoring force for the pressing ring 16. The limiting plate 18 restricts the movement range of the pressing ring 16 to prevent it from dislodging. Through the above design, quick connection and separation of the docking cylinder 8 and the sleeve 7 are achieved, simplifying the disassembly and installation process of the vent pipe and improving maintenance efficiency.

[0025] During operation, if one vent pipe becomes blocked, the other vent pipe can still allow normal gas flow through the sliding action of the first piston 4 or the second piston 11. The specific operating principle is as follows: The first piston 4 slides backward within the first connecting pipe 2, compressing the first spring 5, while the first limiting rod 6 restricts its sliding range. The second piston 11 maintains its initial position within the second connecting pipe 9, with the second spring 12 providing the reset force. Through the operation of the pressing ring 16, the elastic ball 14 disengages from the groove 15 on the inner wall of the sleeve 7, separating the docking cylinder 8 from the sleeve 7, thus achieving rapid disassembly of the second connecting pipe 9. Under external force, the pressing ring 16 moves axially along the docking cylinder 8, compressing the third spring 17. The elastic ball 14 retracts inward due to the movement of the pressing ring 16, disengaging from the groove 15 on the inner wall of the sleeve 7. When the external force is removed, the third spring 17 pushes the pressing ring 16 back to its original position, and the elastic ball 14 pops out again and engages with the groove 15, completing the locking process. This design not only simplifies the disassembly and installation of the ventilator, but also improves maintenance efficiency.

[0026] The sliding motion of the first piston 4 and the second piston 11 is precisely controlled by the restoring force of the springs. The sliding range of the first piston 4 within the first connecting pipe 2 is limited by the first limiting rod 6, ensuring that it will not dislodge or exceed its predetermined stroke due to excessive external force. The sliding range of the second piston 11 within the second connecting pipe 9 is limited by the second limiting rod 13, similarly ensuring the stability of its movement. The elastic coefficients of the first spring 5 and the second spring 12 are precisely calculated to provide sufficient restoring force while preventing the pistons from failing to slide properly due to excessive elasticity.

[0027] Both ends of the vent fitting 19 are equipped with threaded end caps 20, facilitating cleaning and maintenance of the interior of the vent fitting. The specific cleaning process is as follows: Unscrew the threaded end caps 20 to expose the internal space of the vent fitting 19. Use a cleaning tool to clean the interior of the vent fitting 19. After cleaning, tighten the threaded end caps 20 again to complete the seal. This design not only simplifies the cleaning process but also effectively avoids the problem of internal scale buildup caused by long-term use.

[0028] Through the above technical solution, this utility model achieves the following technical effects: First, the dual-vent pipe design solves the problem of easy blockage and inconvenient cleaning of a single vent pipe in the prior art. When one vent pipe is blocked, the other vent pipe can still work normally without shutting down the processing equipment, thus significantly improving the operating efficiency of the equipment. Second, the cooperative design of the elastic ball 14 and the slot 15 enables quick connection and separation of the docking cylinder 8 and the sleeve 7, facilitating the disassembly and cleaning of the vent pipe and further improving maintenance efficiency. Third, the design of the first piston 4, the second piston 11, and their matching springs ensures precise control of gas flow while avoiding unexpected actions caused by external interference. Finally, the reasonable layout of the components makes the overall structure more compact and suitable for the internal space constraints of various processing equipment.

[0029] The internal ventilation pipe structure of the processing equipment provided by this utility model is characterized by high efficiency, reliability, and ease of maintenance. It is suitable for various application scenarios in the field of fluid transmission and control, and is especially suitable for industrial environments requiring high reliability and high maintenance efficiency. Through the description of the above specific embodiments, those skilled in the art can clearly understand the technical solution of this utility model and can adjust and optimize it according to actual needs to meet the application requirements of different scenarios.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
