[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-2 This utility model provides an embodiment of a quick-change flange joint for a multi-density material distribution pipeline in a silo. The flange 1 is the core connecting component of the entire quick-change flange joint. A sealing gasket 2 is installed on the outer side of the axial center of its left surface. Through cooperation with another mating flange, the sealing gasket 2 achieves a sealed connection, ensuring the airtightness of the material transfer process within the silo. A disassembly and assembly component 3 is installed at the axial center of the right surface, facilitating quick disassembly and assembly with pipelines and other components, thereby enabling rapid pipeline replacement. An auxiliary component 4 is installed on the outer side of the left surface near the sealing gasket 2, further enhancing the reliability of the connection and the sealing effect. The flange 1 has a sealing gasket 2 on the outer side of the left surface of the flange 1 at the center of the shaft. When the quick-connect flange is connected to other components, it plays a key sealing role, effectively preventing leakage of materials in the hopper during the transfer process, ensuring the cleanliness of the production environment and the integrity and accuracy of material transfer, and avoiding potential safety hazards or equipment damage caused by material leakage. The flange 1 has a disassembly assembly 3 on the right surface of the flange 1 at the center of the shaft, and an auxiliary assembly 4 on the outer side of the left surface of the flange 1 near the sealing gasket 2.
[0024] Reference Figures 2-4The disassembly assembly 3 includes an installation cylinder 31, which is fixedly installed at the center of the right surface of the flange 1. The installation cylinder 31 provides an installation base and support for other components in the subsequent disassembly assembly 3, forming a tubular structure that facilitates docking with pipes and other components. It achieves a sealed connection with the connecting pipe 36 through the sealing ring 32 on its inner wall, ensuring the sealing of the internal material transmission channel. The sealing ring 32 is embedded in the inner wall of the installation cylinder 31. When the connecting pipe 36 is inserted into the installation cylinder 31, it fits tightly with the connecting pipe 36, further enhancing the sealing performance at the connection and preventing material leakage from the gap between the installation cylinder 31 and the connecting pipe 36, thus ensuring the sealing reliability of the entire material transmission system. A fixing collar 33 is fixedly installed on the outer wall of the installation cylinder 31. The fixing collar 33 serves to connect and fix the handle 35, and at the same time provides limit and support for the installation of the connecting pipe 36, ensuring that the connecting pipe 36 can be stably installed in the installation cylinder 31 and make good contact with the sealing ring 32 to achieve a sealing effect.
[0025] Reference Figures 2-4 Mounting seats 34 are fixedly installed at both ends of the outer wall of the fixing collar 33. The mounting seats 34 are used to hinge the handle 35, providing a fulcrum and fixed base for the handle 35, allowing the handle 35 to rotate flexibly around the mounting seat 34, thereby realizing the quick clamping or loosening operation of the connecting pipe 36, facilitating the disassembly and replacement of the pipe. The handle 35 is hinged inside the mounting seat 34. By operating the handle 35, the connecting pipe 36 can be quickly fixed and disassembled. When it is necessary to connect the pipe, rotate the handle 35 to make it cooperate with the fixing collar 33 to clamp the connecting pipe 36, ensuring that the connecting pipe 36 is properly secured. The connection between the cylinders 31 is tight and the seal is reliable. When the pipe needs to be disassembled, the connecting pipe 36 can be quickly released by turning the handle 35 in the opposite direction. The operation is simple and quick, which greatly improves the efficiency of pipe replacement. The inner wall of the fixing collar 33 is detachably connected to the connecting pipe 36. The outer surface of the connecting pipe 36 is set with an arc-shaped structure. The connecting pipe 36 is fixed in the inner wall of the cylinder 31 by the sealing ring 32. The connecting pipe 36 is inserted into the cylinder 31 and fixed by the handle 35 to achieve quick connection with the flange 1, thereby connecting the silo with other pipes or equipment and ensuring smooth material transmission. Its arc-shaped structure design helps to increase the contact area and sealing effect with the sealing ring 32, enhancing the reliability and sealing of the connection.
[0026] Reference Figures 2-4The auxiliary component 4 includes a storage slot 41, which is located outside the positioning slot 43. The storage slot 41 is used to place the hollow cylinder 47, providing installation space and support for the hollow cylinder 47, allowing it to be stably positioned in a predetermined location. The storage slot 41 is compatible with the cross-sectional area of the inner wall of the hollow cylinder 47, ensuring that the hollow cylinder 47 will not shake or shift after insertion, thus guaranteeing the stability of the entire auxiliary component 4 structure. This effectively supports and positions the sealing gasket 2, enabling it to maintain a stable position and shape under stress, thereby improving sealing performance. Multiple positioning slots 43 are provided on the left surface of the flange 1. The positioning slots 43 are used to engage with the sealing gasket 2. The components work together to position the gasket 2, ensuring it is accurately installed in the predetermined position and preventing displacement or shifting during use, thus ensuring the reliability of the sealing effect. Auxiliary grooves 42 are provided on both the upper and lower sides of the left surface of the flange 1 near the storage groove 41. These auxiliary grooves 42 provide installation space and range of motion for the telescopic rod 44 and other connected components. The bottom surface of the inner wall of the auxiliary groove 42 is fixedly connected to the telescopic rod 44, which provides support and guidance for the pad 46, allowing the pad 46 to move stably within the auxiliary groove 42 along the direction of the telescopic rod 44.
[0027] Reference Figures 2-4The telescopic end of the telescopic rod 44 is elastically connected to a pad 46 via a spring 45. The top end of the spring 45 is fixedly connected to the lower surface of the pad 46, and the bottom end of the spring 45 is fixedly connected to the telescopic end of the telescopic rod 44. The spring 45 serves as an elastic support and a reset function. When an external force is applied to the sealing gasket 2, the spring 45 is compressed, causing the gasket 46 to move the hollow cylinder 47 downwards, thereby adjusting the stress state of the sealing gasket 2 and making it fit more tightly with the mating parts, enhancing the sealing effect. When the external force disappears, the elastic force of the spring 45 causes the gasket 46 to return to its original position, ensuring that the sealing gasket 2 can quickly return to its initial sealing state, ensuring that the entire sealing system is always in good working condition. A circular groove is provided at the axis of the gasket 46, and the cross-sectional area of the circular groove of the gasket 46 is adapted to the cross-sectional area of the positioning groove 43. The gasket 46 is connected to the placement groove 41 through the cooperation of the hollow cylinder 47, so that when the gasket 46 is subjected to external force and adjusted by the extension and retraction of the spring 45 and the telescopic rod 44, it can drive the hollow cylinder 47 to move accordingly, thereby enabling the sealing gasket 2 to flexibly adapt to changes in force, maintain sealing performance, and Furthermore, the gasket 46, positioning groove 43, and other components in the auxiliary assembly 4 cooperate with each other to form a complete auxiliary support and sealing system, ensuring the stability and sealing reliability of the flange 1 during connection. A hollow cylinder 47 is fixedly installed at the axial center of the lower surface of the gasket 46. The cross-sectional area of the inner wall of the storage groove 41 is compatible with the cross-sectional area of the inner wall of the hollow cylinder 47. The hollow cylinder 47 is connected through the inner wall of the storage groove 41. The hollow cylinder 47 not only provides a stable support point for the gasket 46, enabling it to move smoothly in the auxiliary groove 42, but also further enhances the positioning effect of the sealing gasket 2 through its cooperation with the storage groove 41, ensuring that the sealing gasket 2 always maintains the correct position and shape during operation, effectively preventing material leakage from the periphery of the sealing gasket 2, and improving the sealing performance and connection stability of the entire quick-connect flange joint.
[0028] Working principle:
[0029] In the disassembly and assembly assembly 3, the mounting cylinder 31 is fixedly installed at the center of the right surface of the flange 1, and a sealing ring 32 is embedded in its inner wall. When the connecting pipe 36 is inserted into the mounting cylinder 31, the sealing ring 32 fits tightly with the connecting pipe 36, further enhancing the sealing performance of the connection and preventing material leakage. The fixing collar 33 is fixedly installed on the outer wall of the mounting cylinder 31, and the mounting seats 34 at both ends of its outer wall are hinged with handles 35. By operating the handles 35, the connecting pipe 36 can be quickly fixed and disassembled. When it is necessary to connect the pipe, turn the handle 35 to make it cooperate with the fixing collar 33 to clamp the connecting pipe 36, ensuring that the connection between the connecting pipe 36 and the mounting cylinder 31 is tight and the seal is reliable. When it is necessary to disassemble the pipe, turn the handle 35 in the opposite direction to quickly release the connecting pipe 36. The operation is simple and quick, which greatly improves the efficiency of pipe replacement.
[0030] An auxiliary component 4 is provided on the left surface of flange 1 near the outer side of gasket 2. This auxiliary component 4 further enhances the reliability of the connection and the sealing effect, and provides auxiliary support and positioning for gasket 2. A storage groove 41 is provided on the outer side of positioning groove 43 for placing hollow cylinder 47, providing installation space and support for hollow cylinder 47. Multiple positioning grooves 43 are provided on the left surface of flange 1 to cooperate with components such as gasket 2, providing positioning for gasket 2 and preventing gasket 2 from malfunctioning during use. In case of displacement or offset, to ensure the reliability of the sealing effect, a telescopic thin rod 44 is fixedly connected to the bottom surface of the inner wall of the auxiliary groove 42. The telescopic end of the rod is elastically connected to a pad 46 via a spring 45. A circular groove is opened at the axis of the pad 46, and its cross-sectional area is adapted to the cross-sectional area of the positioning groove 43. A hollow cylinder 47 is fixedly installed at the axis of the lower surface of the pad 46. The cross-sectional area of the inner wall of the storage groove 41 is adapted to the cross-sectional area of the inner wall of the hollow cylinder 47. The hollow cylinder 47 is connected through the inner wall of the storage groove 41.
[0031] When an external force is applied to the sealing gasket 2, the spring 45 is compressed, causing the gasket 46 to move the hollow cylinder 47 downwards, thereby adjusting the stress state of the sealing gasket 2 and making it fit more tightly with the mating parts, enhancing the sealing effect. When the external force disappears, the elasticity of the spring 45 causes the gasket 46 to reset, ensuring that the sealing gasket 2 can quickly return to its initial sealing state, ensuring that the entire sealing system is always in good working condition. Through the synergistic effect of the components in the auxiliary assembly 4, the positioning effect of the sealing gasket 2 is further enhanced, ensuring that the sealing gasket 2 always maintains the correct position and shape during operation, effectively preventing material leakage from the periphery of the sealing gasket 2, and improving the sealing performance and connection stability of the entire quick-change flange joint.
