Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a detachable gas collecting and exhausting structure. Background Art

[0002] In industrial production, pipe boxes are one of the common equipment used to store and transport fluid media. In order to ensure that the fluid medium in the pipe box can flow smoothly and prevent safety problems caused by gas accumulation, it is necessary to design a gas collecting and exhaust structure. When the water side of the tube-side pipe box of the traditional steam-water heat exchanger needs to be exhausted, in addition to the drain outlet pipe, an exhaust pipe and a corresponding exhaust structure inside the corresponding pipe box are also required. The general exhaust structure is that the exhaust duct is connected to the exhaust pipe, and the exhaust pipe can only be set below the partition plate. The exhaust duct cannot pass through the partition plate, so that the exhaust pipe is set above the pipe box, which is not convenient for exhaust. Therefore, it is of great significance to develop a gas collecting and exhaust structure with a simple structure, easy to disassemble and clean. Utility Model Content

It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the utility model, and the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] This embodiment discloses a detachable gas collecting and exhausting structure, which is installed inside the pipe box 12 and is used to collect and exhaust the gas in the pipeline. Figure 1-Figure 4 As shown, it includes a base plate 1, an extended pipe section 2, an exhaust pipe section 3, and an exhaust pipe 4, wherein the base plate 1 is a rectangular metal plate fixed to the bottom of the pipe box 12 along the length direction of the pipe box 12, and a plurality of air inlet holes 5 are opened on the base plate 1, and these holes allow gas to enter the gas collecting structure from the bottom of the pipe box 12.

[0026] The extension pipe section 2 is made of stainless steel and is buckled on the top of the bottom plate 1. Similarly, the exhaust pipe section 4 is made of stainless steel and is buckled on the top of the bottom plate 1. The extension pipe section 2 and the exhaust pipe section 4 are docked and matched with each other to form a gas collection space for collecting water vapor and other gases. An exhaust hole 6 is provided on the top of the exhaust pipe section 4, one end of the exhaust pipe 4 is connected to the exhaust hole 6, and the other end of the exhaust pipe 4 is connected to the upper part of the pipe box 12, and the other end of the exhaust pipe 4 is connected to the outside. The gas gathered in the extension pipe section 2 and the exhaust pipe section 4 can be discharged to the outside of the pipe box 12 through the exhaust pipe 4.

[0027] During operation, first, the base plate 1 is installed inside the pipe box 12 along the length direction of the pipe box 12. An air inlet 5 is provided at the bottom of the base plate 1 to guide water vapor into the system. The bottom of the extension pipe section 2 and the bottom of the exhaust pipe section 4 3 are buckled on top of the base plate 1 to form a closed space, which is conducive to the collection and transmission of gas. The extension pipe section 2 and the exhaust pipe section 4 3 are docked with each other, and the positions of these two parts can be replaced with each other, which increases the flexibility of the structure. An exhaust hole 6 is provided at the top of the exhaust pipe section 4 3, which allows gas to be discharged from the system. One end of the exhaust pipe 4 is connected to the exhaust hole 6, and the other end is interconnected with the upper part of the pipe box 12, and ensures that this end is connected to the external environment. This design can effectively guide the gas from the inside of the pipe box 12 to the external environment.

[0028] In some optional implementations, in order to adapt to pipe boxes 12 of different lengths, multiple groups of extended pipe sections 2 are required to be provided. The length of the extended pipe sections 2 can be adjusted according to the length of the pipe box 12, and the multiple groups of extended pipe sections 2 are respectively connected to each other or to the exhaust pipe 4 sections 3.

[0029] In some optional embodiments, the top of the extension pipe segment 2 and the top of the exhaust pipe segment 4 3 are both arc-shaped tops that gradually bulge toward the middle on both sides. The design of the arc-shaped top can not only improve the structural strength of the extension pipe segment 2 and the exhaust pipe segment 4 3, but also allow the gas to better gather at the center of the top, thereby improving the efficiency of gas collection and exhaust.

[0030] In some optional embodiments, in order to connect the exhaust pipe 4 with the exhaust pipe section 4 3, a boss 7 is provided on the top of the exhaust pipe section 4 3, the upper surface of the boss 7 is a plane, the exhaust hole 6 is provided on the plane, and the exhaust pipe 4 is connected to the exhaust hole 6 through the plane. Since the exhaust pipe 4 is connected to the exhaust pipe section 4 3 on the plane, the connection can be made more convenient and the initial sealing of the connection can be improved.

[0031] In some optional embodiments, in order to improve the stability of the connection between the extension pipe segment 2 and the extension pipe segment 2 and the extension pipe segment 2 and the exhaust pipe segment 4 3, connecting flanges 8 are provided at both ends of the extension pipe segment 2 and the exhaust pipe segment 4 3, and the extension pipe segment 2 and the exhaust pipe segment 4 3 are threadedly connected to each other through the connecting flanges 8.

[0032] In some optional embodiments, since the extension pipe segment 2 and the exhaust pipe segment 4 3 are relatively heavy, a crane is required to lift them during the installation process. In order to facilitate the connection with the lifting cable, a lifting lug 11 is provided at the top of the extension pipe segment 2 and the top of the exhaust pipe segment 4 3. The lifting lug 11 is connected to the cable to facilitate the lifting of the extension pipe segment 2 and the exhaust pipe segment 4 3.

[0033] In some optional embodiments, since the structure needs to be installed in pipe boxes 12 of different specifications, the distances between pipe boxes 12 of different specifications and exhaust pipe section 4 section 3 will be different. In order to adapt to different distances, the exhaust pipe 4 is configured to be a first tube body 40 and a second tube body 41. One end of the first tube body 40 is connected to the exhaust pipe section 4 section 3, the other end of the first tube body 40 is connected to one end of the second tube body 41, and the other end of the second tube body 41 is connected to the pipe box 12. Specifically, the first tube body 40 and the second tube body 41 are connected by threads. During the installation process, the second tube body 41 is rotated to change the matching length of the first tube body 40, thereby controlling the total length of the first tube body 40 and the second tube body 41. By controlling the total length of the first tube body 40 and the second tube body 41, the purpose of adapting to pipe boxes 12 of different specifications is achieved.

[0034] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
