[0026] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.
[0027] Embodiment: A high temperature conical filter, such as Figure 1-Figure 4 As shown, it includes a barrel 1 and a flange 2.
[0028] The cylinder body 1 is a conical cylinder, with an opening at the end with a larger diameter and a cylinder bottom at the end with a smaller diameter. The conical structure is conducive to the precipitation of solid particles and their concentration at the bottom of the cylinder, which is convenient for subsequent cleaning operations and maintenance. The cylinder body 1 and the cylinder bottom are both composite mesh components composed of several layers of mesh, which can be graded for different particle sizes. At the same time, the multi-layer mesh increases the filtering area and the ability to intercept impurities, which helps to extend the service life of the filter and improve the filtering accuracy.
[0029] The longitudinal cross-sectional area of the flange 2 gradually increases from one end of the flange 2 to the other end of the flange 2, forming a tapered structure, the taper of which is consistent with the taper of the inner wall of the open end of the barrel 1. The outer wall of the smaller end of the flange 2 is fixedly connected to the inner wall of the open end of the barrel 1, ensuring a smooth transition and good sealing at the connection between the flange 2 and the barrel 1, thereby reducing the risk of leakage during operation of the equipment. At the same time, the outer wall of the end of the flange 2 is used to support the inner net of the barrel 1, so as to achieve the purpose of improving the connection effect between the inner net of the barrel 1 and the flange 2.
[0030] A flow guide hole 3 is provided inside the flange 2, and the flow guide hole 3 extends from one end of the flange 2 to the other end of the flange 2, and one end of the flow guide hole 3 is connected to the inside of the cylinder body 1, and the other end of the flow guide hole 3 is a natural gas inlet for receiving high-temperature natural gas to be filtered, so that the natural gas can evenly enter the filtering area in the cylinder body 1 from the other end of the flange 2 through the flow guide hole 3.
[0031] For example, in order to improve the stability of the connection between the barrel 1 and the flange 2. In this embodiment, the flange 2 is further optimized, and a first connecting groove 4 is added to the outer wall of one end of the flange 2. Figure 2 or Figure 4 As shown, the first connection groove 4 extends from one end of the flange 2 to the other end of the flange 2. And the groove wall of the first connection groove 4 gradually moves away from the guide hole 3 from one end of the flange 2 to the other end of the flange 2, so that the groove wall of the first connection groove 4 has a conical structure with the same taper as the inner wall of the opening end of the barrel 1. Figure 1 or Figure 3 As shown, the groove wall of the first connecting groove 4 and the inner wall of the open end of the barrel 1 can be mechanically connected (such as welding or nesting) to form a sealed and strong joint surface, thereby enhancing the stability and sealing performance of the overall structure.
[0032] Likewise, if Figure 1 or Figure 3 As shown, the bottom of the first connection groove 4 is also mechanically connected (for example, by welding or nesting) to the end surface of the open end of the barrel body 1, thereby improving the connection stability and sealing performance between the barrel body 1 and the flange 2.
[0033] For example, in order to further improve the mechanical strength of the connection between the flange 2 and the barrel 1. Figure 1 or Figure 3 As shown, in this embodiment, the bottom of the first connecting groove 4 and the end face of the open end of the barrel 1 are welded continuously and evenly by welding processes such as argon arc welding and gas shielded welding to ensure the formation of a firm and sealed welded joint. On the one hand, the flange 2 is tightly connected to the barrel 1 by welding, which significantly enhances the mechanical strength between the two, so that the entire filter remains stable when subjected to pressure, high temperature and material impact, and is not prone to deformation or breakage. On the other hand, the seamless connection formed by welding greatly improves the sealing of the connection part, effectively preventing leakage problems that may occur in high temperature and high pressure working environments, and ensuring the safe operation of the equipment.
[0034] For example, in order to further improve the mechanical strength of the connection between the flange 2 and the barrel 1. In this embodiment, Figure 1 or Figure 3 As shown, the welding surface between the bottom of the first connecting groove 4 and the end surface of the opening end of the barrel 1 also includes an end of the groove wall of the first connecting groove 4 close to the bottom of the first connecting groove 4.
[0035] During the implementation, when the flange 2 is docked with the open end of the barrel 1, it is necessary not only to ensure that the bottom of the first connecting groove 4 and the end face of the open end of the barrel 1 are accurately fitted, but also to ensure that the part of the first connecting groove 4 groove wall near the bottom of the groove is also in close contact with the inner wall of the barrel 1. During the welding operation, in addition to continuous and firm welding of the bottom of the first connecting groove 4 and the end face of the open end of the barrel 1, the welding material between the bottom of the first connecting groove 4 and the end face of the open end of the barrel 1 and the part of the first connecting groove 4 groove wall near the bottom of the groove are fully welded to form a continuous and reliable welding area. On the one hand, through such a welding method, the welding points and welding area of the welding material at the welding position 9 are increased, the rigidity and stability of the entire connection structure are improved, and the impact force generated by the material flow and the vibration stress during the operation of the equipment can be effectively resisted. On the other hand, expanding the welding range to the wall of the first connecting groove 4 reduces the risk of leakage, ensures that the equipment has good sealing performance under high temperature and high pressure environment, and avoids safety problems or reduced efficiency caused by leakage.
[0036] For example, in order to improve the stability of the filter when connected, in this embodiment, the high temperature conical filter is added with a connecting ring 5. Figure 1 , Figure 2 , Figure 3 or Figure 4As shown, the connecting ring 5 is directly connected to the larger diameter end (i.e., the other end) of the flange 2, and is designed as one piece with the flange 2 or fixed by reliable fixing methods such as welding, bolting, etc. A certain space is left between the side wall of the connecting ring 5 close to the smaller end of the flange 2 and the outer wall of the flange 2, forming a second connecting groove 6, which is convenient for placing a gasket in the process of connecting the high-temperature conical filter.
[0037] The second connecting groove 6 facilitates the user to place gaskets on both side walls of the connecting ring 5 when connecting the high-temperature conical filter, so as to improve the stability of the filter when connected.
[0038] For example, in order to further improve the mechanical strength of the connection between the flange 2 and the body 1, in this embodiment, the connection ring 5 of the high temperature conical filter is integrated with the first connection groove 4 of the flange 2. Figure 3 and Figure 4 As shown, the connecting ring 5 is installed or integrally formed on the large diameter end (the other end) of the flange 2, and its side wall close to the small diameter end (one end) of the flange 2 actually constitutes the bottom part of the first connecting groove 4. At this time, the first connecting groove 4 is also the second connecting groove 6.
[0039] That is to say, when the connecting ring 5 and the flange 2 are combined, not only a hand-held portion is provided for the user to hold and move the filter, but also a functional first connecting groove 4 is formed. The design of the first connecting groove 4 ensures the effective docking and fixation between the open end of the barrel 1 and the flange 2, and due to the presence of the connecting ring 5, the strength of the docking point is enhanced.
[0040] Through this structure, on the one hand, by combining the connecting ring 5 with the bottom of the first connecting groove 4, the number of parts and the assembly process are simplified, and the integrity and stability of the equipment are improved. On the other hand, as a part of the first connecting groove 4, the connecting ring 5 increases the welding or fixing area, making the connection between the flange 2 and the barrel 1 more firm and reliable, and the pressure resistance and durability are improved.
[0041] For example, after the barrel 1 and the flange 2 are welded, the welding position 9 needs to be polished and leveled to reduce the risk of abrasion of the side wall of the connecting ring 5 near the flange 2 during the polishing process. Figure 1 and Figure 3 As shown, the ring 7 is sleeved around the outer wall of the flange 2, and the ring 7 and the flange 2 are connected together by welding or integral molding. And the ring 7 is located between the connecting ring 5 and the barrel 1.
[0042] The side wall of the ring 7 close to the barrel 1 constitutes the bottom of the first connecting groove 4. During the welding process, the flange 2 and the barrel 1 are welded and fixed with the ring 7 as an intermediate transition layer, which effectively disperses the welding stress and ensures the flatness and sealing of the weld. At the same time, after welding, when the outer wall is polished to ensure a smooth surface, the presence of the ring 7 makes the connecting ring 5 have a certain distance from the welding position 9 of the ring 7 and the barrel 1, thereby achieving the purpose of reducing the risk of damage to the connecting ring 5 caused by wear during the polishing process.
[0043] The second connecting groove 6 formed between the outer wall of the ring 7 and the side wall of the connecting ring 5 close to the flange 2 reserves a mounting position for the gasket when connecting the high-temperature conical filter.
[0044] Through this structure, on the one hand, the design of the ring 7 makes the welding process more refined, which is conducive to improving the quality and stability of the welded joint and reducing the risk of leakage. On the other hand, the protection of key components such as the connecting ring 5 by the ring 7 reduces unnecessary wear, thereby extending the service life of the entire filter.
[0045] For example, in order to reduce the risk of damage to the user by the connecting ring 5 during the user's use of the high temperature conical filter, in this embodiment, the side wall edge of the connecting ring 5 close to the flange 2 is provided with a chamfer 8, such as Figure 1 , Figure 2 , Figure 3 or Figure 4 As shown, the size and shape of the chamfer 8 meet the requirements of ergonomics, making it more comfortable for the user to hold the device without causing discomfort or scratches to the hand due to sharp edges. In other words, the edge of the connecting ring 5 is processed and is no longer a right angle or an acute angle, but adopts a circular arc transition or a bevel transition to form a smooth, non-right angle edge structure.
[0046] Through this structure, on the one hand, the chamfer 8 can eliminate sharp edges, reduce the risk of cuts or scratches during operation, and ensure the personal safety of the user. On the other hand, the chamfer 8 can provide a smoother contact surface, making the grip more comfortable and reducing hand fatigue during long-term use.
[0047] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
