Description

Technical Field

[0001] This utility model relates to the technical field of natural gas dehydrogenation devices, and in particular to a small-scale natural gas dehydrogenation device. Background Technology

[0002] When natural gas is extracted, it is at a high temperature and humidity, and its internal composition is complex with a high hydrocarbon content, which is not conducive to long-distance transmission and storage. Therefore, it is necessary to perform dehydrocarbonization on natural gas to enable its long-distance transmission and storage. Application No.: CN202321866281.X discloses a small natural gas dehydrocarbonization device, including a main structure, a dehydrocarbonization mechanism, and an auxiliary mechanism. The dehydrocarbonization mechanism is located above the main structure, and the auxiliary mechanism is located inside the main structure... The gas outlet and gas inlet pipes in this patent lack shielding. When left unused for a long time, dust and debris can easily enter the gas inlet and gas outlet pipes, increasing the cleaning burden. Therefore, we have introduced a small natural gas dehydrocarbonization device. Utility Model Content

A pushing device is fixedly connected to the upper front part of the dehydrocarbonization operation box. An inlet pipe is fixedly connected to the upper front part of the dehydrocarbonization operation box. A first-stage sealing device is installed on the outer surface of the inlet pipe. An outlet pipe is fixedly connected to the upper rear part of the dehydrocarbonization operation box. A second-stage sealing device is installed on the outer surface of the outlet pipe. All four corners of the lower end of the device body are equipped with casters with brakes. The first-stage sealing device and the second-stage sealing device have the same structure.

[0006] Preferably, the first sealing device includes a support member, which is an "L"-shaped structure.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A small-scale natural gas dehydrogenation device includes a dehydrogenation operation box 1, a device body 2 connected to the lower end of the dehydrogenation operation box 1, a pushing device 4 fixedly connected to the upper front end of the dehydrogenation operation box 1, an inlet pipe 6 fixedly connected to the upper front end of the dehydrogenation operation box 1, a first sealing device 5 installed on the outer surface of the inlet pipe 6, an outlet pipe 8 fixedly connected to the upper rear end of the dehydrogenation operation box 1, a second sealing device 7 installed on the outer surface of the outlet pipe 8, and universal wheels 3 with brakes installed at the four corners of the lower end of the device body 2. The first sealing device 5 and the second sealing device 7 have the same structure.

[0025] In this embodiment, the first sealing device 5 includes a support member 51, which has an "L"-shaped structure. The upper end of the support member 51 is movably connected to a connecting block 53 via a rotating shaft. The connecting block 53 also has an "L"-shaped structure. A spring piece 52 is fixedly connected to the upper front end of the connecting block 53, and a dustproof plate 54 is fixedly connected to the rear end of the connecting block 53. The support member 51 is fixedly connected to the outer surface of the air inlet pipe 6. The spring piece 52 is inclined. The diameter of the connecting block 53 is the same as the diameter of the air inlet pipe 6, and the connecting block 53 contacts the upper end of the air inlet pipe 6.

[0026] Through the above solution, the support member 51 is movably connected to the connecting block 53 via a rotating shaft, ensuring both a stable connection and flexible rotation. The spring piece 52 at the front end of the connecting block 53 utilizes its own elastic restoring force to keep the connecting block 53 and its rear dustproof plate 54 in a constant position when no external force is applied—that is, always above the air intake pipe 6, effectively forming a barrier.

[0027] In this embodiment, the pushing device 4 includes two connecting rods 41. The outer surfaces of the two connecting rods 41 are each provided with a through-hole 43. The front ends of the outer surfaces of the two connecting rods 41 are fitted with movable tubes 45. The outer surfaces of the two movable tubes 45 are each provided with a plurality of adjusting holes 42. Limiting bolts 44 are inserted and connected to the two movable tubes 45. The front ends of the two movable tubes 45 are fixedly connected to a push rod 46. The two connecting rods 41 are fixedly connected to the front end of the dehydrocarbonization operation box 1.

[0028] By adjusting the sliding position of the two movable tubes 45 on the connecting rod 41, the overall position of the push rod 46 can be flexibly adjusted. This not only enhances the positional adaptability of the push rod 46, but also greatly improves its flexibility of use, allowing the push rod 46 to be adjusted according to different work requirements or space constraints.

[0029] It should be noted that this utility model describes a small natural gas dehydrogenation device, in which the support 51 is movably connected to the connecting block 53 via a rotating shaft, ensuring that the two can be both stably connected and flexibly rotated. The spring plate 52 at the front end of the connecting block 53 utilizes its own elastic restoring force to push the connecting block 53 and its rear dustproof plate 54 to remain in a constant position when no external force is applied—that is, always above the air intake pipe 6. This effectively forms a barrier, preventing external dust and impurities from entering the air intake pipe 6, ensuring the cleanliness and operating efficiency of the air intake system. A movable tube 45 is fitted onto the outer surface of each of the two connecting rods 41. These two movable tubes 45 are structurally independent, but their front ends are connected by a push rod 46. Users can easily adjust the sliding position of the two movable tubes 45 on the connecting rods 41 to flexibly adjust the overall position of the push rod 46. This not only enhances the positional adaptability of the push rod 46 but also greatly improves its flexibility of use, allowing the push rod 46 to be precisely positioned to the optimal operating position according to different work requirements or space constraints.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
