Description

Technical Field

[0001] This utility model relates to the field of gas transmission technology, and in particular to a gas pressure regulating and transmission device. Background Technology

[0002] Urban gas is an essential component of a complete set of modern facilities for building modern cities. Developing urban gas can significantly improve the efficiency of heat energy utilization. It is not only a necessity for the modernization of cities, but also an important measure to save energy consumption, protect the urban environment, and improve people's living standards.

[0003] A Chinese patent, CN221958689U, discloses a gas pressure regulating and conveying device. This device effectively filters impurities and particulate matter in the gas, such as dust, sand, and corrosive substances. If these impurities are not filtered out, they may damage or clog the device and other equipment. Filtering out these impurities reduces wear and tear on the device and other equipment, extends their service life, and ensures stable and safe operation. However, the spacing between the multiple filter elements cannot be adjusted. If the spacing is too large, it may affect the filtration effect; if the spacing is too small, it may increase the filter resistance and reduce the gas flow. Adjusting the position of the multiple filter elements is also inconvenient. Therefore, this patent proposes a gas pressure regulating and conveying device to solve these problems. Utility Model Content

[0004] This utility model provides a gas pressure regulating and conveying device, including a filter frame, a gas pressure regulating and conveying device body, an outlet pipe and an inlet pipe. The outlet pipe and the inlet pipe are respectively connected to the front and rear sides of the filter frame, and the gas pressure regulating and conveying device is connected to the rear side of the inlet pipe. It also includes a movable frame, multiple U-shaped frames and multiple filter elements. The movable frame is slidably disposed in the filter frame, the multiple U-shaped frames are spaced apart in the movable frame, and the multiple filter elements are respectively disposed in the multiple U-shaped frames. An adjustment mechanism is provided on the right side of the movable frame to adjust the spacing between the multiple U-shaped frames.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] like Figure 1-3 As shown, the present invention proposes a gas pressure regulating and conveying device, including a filter frame 1, a gas pressure regulating and conveying device body, an outlet pipe 2 and an inlet pipe 3. The outlet pipe 2 and the inlet pipe 3 are respectively connected to the front and rear sides of the filter frame 1, and the gas pressure regulating and conveying device is connected to the rear side of the inlet pipe 3. It also includes a movable frame 5, multiple U-shaped frames 6 and multiple filter elements 7. The movable frame 5 is slidably disposed in the filter frame 1, the multiple U-shaped frames 6 are spaced apart in the movable frame 5, and the multiple filter elements are respectively disposed in the multiple U-shaped frames 6. An adjustment mechanism is provided on the right side of the movable frame 5 to adjust the spacing between the multiple U-shaped frames 6.

[0021] In this invention, the filter frame 1 is located on the front side of the gas pressure regulating and conveying device body and is connected to it by an air inlet pipe 3. Gas enters the filter frame 1 from the gas pressure regulating and conveying device body through the air inlet pipe 3 and is then filtered. During filtration, the spacing between the multiple U-shaped frames 6 is adjusted from the outside of the movable frame 5, thereby adjusting the spacing between the multiple filter elements 7. A reasonable spacing setting can reduce the flow resistance of gas between the filter layers and reduce energy consumption. When the spacing is too small, gas flow may be obstructed, resulting in increased filtration resistance. Appropriately increasing the spacing can reduce this resistance and allow gas to pass through the filtration system more smoothly.

[0022] In an optional embodiment, sliding rods 51 are slidably provided on both the front and rear sides of the movable frame 5, and sliders are connected to opposite sides of the two sliding rods 51.

[0023] It should be noted that by setting the slide bar 51 and the movable frame 5, the movable frame 5 can be removed from the right side of the filter frame 1, and then the filter element 7 can be replaced.

[0024] In an optional embodiment, the adjustment mechanism includes two fixed plates 81, a limiting rod 82, multiple movable plates 83, multiple connecting rods 84, a folding frame 85, and a drive assembly. The two fixed plates 81 are spaced apart and connected to the front side of the movable frame 5. The limiting rod 82 is connected between the two fixed plates 81. The multiple movable plates 83 are slidably sleeved on the limiting rod 82 and are respectively connected to multiple U-shaped frames 6 through multiple connecting rods 84. The folding frame 85 is disposed on the multiple movable plates 83, and the drive assembly is disposed on the right fixed plate 81.

[0025] In an optional embodiment, the drive assembly includes a fixing member 86 and a threaded rod 87. The fixing member 86 is connected to the right side of the movable frame 5. One end of the threaded rod 87 is rotatably connected to the rear side of the fixing member 86, and the other end extends to the rear side of the right-side fixing plate 81. The rightmost movable plate 83 is threadedly connected to the threaded rod 87.

[0026] In an optional embodiment, the front side of the movable frame 5 is provided with a sliding window that is adapted to the size of the plurality of connecting rods 84.

[0027] It should be noted that when adjusting the spacing between multiple U-shaped frames 6, the frame door is first opened, the threaded rod 87 is turned to drive the rightmost moving plate 83 to move, the folding frame 85 drives the other multiple moving plates 83 to move simultaneously, and the connecting rod 84 drives the multiple U-shaped frames 6 to move, thereby changing the spacing between multiple filter elements 7.

[0028] In an optional embodiment, a frame door is provided on the right side of the filter frame 1, and a collection hopper 4 is provided at the bottom of the filter frame 1.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
