Description

Technical Field

[0001] The utility model relates to the technical field of suction devices, and particularly relates to a nylon monomer suction device. Background Technique

[0002] In the spinning process, the molten polymer is ejected through a spinneret and cooled to form primary fibers. Since the polymer contains a certain amount of monomers and oligomers, the monomers and oligomers precipitate in the high-temperature molten state to form smoke. In order to prevent the smoke from spreading in the workshop, a suction hood device is used to suck the precipitated monomers. The monomer suction pipe is used to generate negative pressure. After the monomer suction pipe is connected to the suction hood, the smoke passes through the suction hood and is sucked into the monomer suction pipe.

[0003] In the structure of the existing monomer suction pipe, a flushing water pipe is connected to the upper part of a sealed pipe, and the flushing water pipe flushes water downward, so that negative pressure is generated in the sealed pipe. The sealed pipe is connected to the suction hood through a smoke pipe. During suction, the smoke enters the smoke pipe through the smoke pipe. Driven by the water flow, most of the smoke moves downward, and a small part of the monomer smoke will condense into monomer polymers and adhere to the upper part of the sealed pipe. Over time, the monomer polymers will block the sealed pipe, resulting in a decrease in suction force. Since the top of the sealed pipe is welded, if the sealed pipe needs to be cleaned, the whole sealed pipe needs to be laid down, which is inconvenient for cleaning. Content of the Utility Model

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] The present utility model provides a Figures 1-3 nylon monomer suction device as shown, including a first pipe 1, and a second pipe 2 is fixedly connected to one side of the first pipe 1;

[0033] Furthermore, a sealing mechanism 3 is provided outside the first pipeline 1. The sealing mechanism 3 includes: a fixing ring 31, a sealing cover 32, a flushing pipe 33, a clamping component 34, and a sealing component 35. The fixing ring 31 is fixedly sleeved outside the first pipeline 1; the sealing cover 32 is sleeved outside the first pipeline 1, and the sealing cover 32 is threadedly inserted into the inner cavity of the fixing ring 31. By connecting the fixing ring 31 and the sealing cover 32, the first sealing gasket 351 can be tightly attached to the bottom end of the inner wall of the fixing ring 31, thus forming the first layer of seal; the flushing pipe 33 is slidably inserted into the top end of the sealing cover 32. When the flushing pipe 33 flushes water downward, a negative pressure can be formed in the inner cavity of the first pipeline 1, so that the second pipeline 2 can absorb the smoke; the clamping component 34 is arranged inside the fixing ring 31; the sealing component 35 is arranged on the sealing cover 32 to block the gaps between the sealing cover 32, the first pipeline 1, and the flushing pipe 33.

[0034] Specifically, the clamping component 34 includes: a clamping rod 341, a pull rod 342, a compression spring 343, a slider 344, and a disassembly ring 345. Clamping grooves are formed on both sides of the inner wall of the fixing ring 31, and clamping holes are formed on both sides of the sealing cover 32. One end of the clamping rod 341 is slidably inserted into the inner cavity of the clamping groove, and the other end of the clamping rod 341 is slidably inserted into the inner cavity of the clamping hole. An inclined surface is formed at the other end of the clamping rod 341; one end of the pull rod 342 is fixedly connected to the clamping rod 341, and the other end of the pull rod 342 is slidably inserted into the inner wall of the clamping groove; the compression spring 343 is sleeved outside the pull rod 342. One end of the compression spring 343 is fixedly connected to the inner wall of the clamping groove, and the other end of the compression spring 343 is fixedly connected to the clamping rod 341. The compression spring 343 is always in a compressed state, so as to provide a stable elastic force for the clamping rod 341, enabling the clamping rod 341 to be stably clamped with the clamping hole, facilitating the positioning of the sealing cover 32 and preventing the sealing cover 32 from loosening due to machine vibration. Sliding grooves are formed on both sides of the fixing ring 31, and the slider 344 is slidably inserted into the inner cavity of the sliding groove; the disassembly ring 345 is sleeved outside the fixing ring 31, and multiple sliders 344 are fixedly connected to the disassembly ring 345. Inclined surfaces are formed on both sides of the disassembly ring 345, and sliding grooves for the pull rod 342 to slide are formed on the inclined surfaces. The pull rod 342 can be extruded by using the sliding grooves on the inclined surfaces, so that the pull rod 342 pulls the clamping rod 341, causing the clamping rod 341 to disengage from the clamping hole. At this time, the sealing cover 32 can be disassembled.

[0035] Specifically, the sealing assembly 35 includes: a first sealing ring 351, a second sealing ring 352, and a third sealing ring 353. The first sealing ring 351 is embedded in the bottom of the sealing cover 32; the second sealing ring 352 is fixedly connected to the inner wall of the sealing cover 32. The cross-sectional width of the second sealing ring 352 is the same as the wall thickness of the first pipe 1. An inclined surface is provided at the top end of the second sealing ring 352, which can seal the gap between the sealing cover 32 and the first pipe 1 from the inside, making the sealing performance better. At the same time, it can also prevent water droplets from sliding down along the inner wall of the sealing cover 32 into the gap between the sealing cover 32 and the first pipe 1, affecting the use; the third sealing ring 353 is fixedly sleeved outside the flushing pipe 33, which can seal the gap between the flushing pipe 33 and the sealing cover 32.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
