Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field related to spinning production, in particular to an exhaust device for a water-washing pipeline in high-speed continuous spunbond production. Background Art
[0002] Viscose continuous spinning is an advanced process for the efficient production of viscose filaments. Its notable feature is that it can achieve continuous production. The spinning speed can reach 120-160 meters per minute, which is 20-60 meters per minute higher than the traditional process. It is particularly suitable for large-scale industrial production. The viscose filaments produced by this process not only have excellent moisture absorption and air permeability, but also have high strength, perfectly combining the comfort of natural fibers and the durability of synthetic fibers. In addition, the physical and chemical indicators of its filaments are more stable, and the finished product joints are fewer, which further improves the product quality. In the production process, in order to ensure the continuity and moisturization of the fiber, the water washing link is crucial. During the water washing process, the washing water needs to be accurately transported to the washing tank to ensure the cleanliness of the fiber and the quality of subsequent processing. During the water washing, in order to ensure the quality of the water washing, it is necessary to add monobasic acid to the water washing tank, but it still has the following disadvantages in actual use:
[0003] In the process of high-speed continuous spinning washing pipeline water discharge, when the water is discharged directly, after there are certain bubbles in the water, a cavity will be formed at the water discharge position. There is a large impact when the water is discharged, which can easily cause the water in the washing tank to splash out. The monobasic acid in the water will cause pollution to the surrounding working environment and affect the safety of the working environment;
[0004] Secondly, during the exhaust process of the water washing pipeline, the operator needs to determine the exhaust time and know that during exhaust, it is easy for the cleaning water to spray out due to excessive exhaust. If the exhaust time is too short, it will require multiple operations. It is not convenient to determine whether the water washing pipeline needs to be vented and whether the exhaust is completed. Utility Model Content
[0005] The utility model aims to provide an exhaust device for a water washing pipeline in high-speed continuous spunbond production. By arranging a conveying chamber, a feeding chamber and a transfer chamber, the utility model solves the problem that the water outlet of the high-speed continuous spinning water washing pipeline has no exhaust, which easily causes the water in the washing tank to splash out due to the conveying impact caused by bubbles, and it is not convenient to determine whether the water washing pipeline needs to be exhausted and whether the exhaust is completed.
[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0007] The utility model discloses an exhaust device for a water-washing pipeline in high-speed continuous spunbond production, comprising a conveying chamber, a feeding chamber and a transfer chamber. A vertical conveying frame is fixedly connected to the peripheral side of the feeding chamber, a side of the conveying frame away from the feeding chamber is fixedly connected to the conveying chamber, an exhaust pipe is fixedly connected to the upper part of the peripheral side of the conveying chamber, a top of the exhaust pipe is fixedly connected to the transfer chamber, a movable rod is fixed in the transfer chamber, a float is movably connected to the peripheral side of the movable rod, and when working, cleaning water is conveyed through the conveying chamber, bubbles in the cleaning water rise and are conveyed to the transfer chamber through the exhaust pipe, and then are conveyed into the cleaning water through the feeding chamber, and the cleaning water is transferred through the transfer chamber.
[0008] Furthermore, the bottom centers of the delivery chamber and the feed chamber are fixedly connected with an output pipe, the peripheral side of each output pipe is fixed with an electric control valve, and the bottom end of each output pipe is fixedly connected with a connecting piece, and the delivery chamber and the feed chamber transport the cleaning water to the water delivery pipeline connected to the connecting piece through the output pipe.
[0009] Furthermore, the lower part of the exhaust pipe is arranged obliquely, and the upper part of the exhaust pipe is arranged vertically. When the exhaust pipe is working, the bubbles in the cleaning water are transported to the transfer chamber through the exhaust pipe.
[0010] Furthermore, an input pipe is fixedly connected to the upper part of the peripheral side of the feed chamber, and the input pipe is arranged obliquely. The input pipe is arranged on the peripheral side of the feed chamber away from the transfer chamber, and the feed chamber inputs the cleaning water into the feed chamber through the input pipe.
[0011] Furthermore, an observation window is fixed through one side of the transfer chamber, and the observation window is arranged close to the movable rod. The movable rod is vertically fixed in the transfer chamber and arranged close to the observation window. The movable rod is arranged on one side of the exhaust pipe from a top-down perspective. When the transfer chamber is working, the operator can observe the float position in the transfer chamber through the observation window.
[0012] Furthermore, an air outlet pipe is fixedly connected to the center of the top of the transfer chamber, and a second electric-controlled valve is fixed on the periphery of the air outlet pipe, and the air outlet pipe is controlled to be on and off by the second electric-controlled valve.
[0013] The utility model has the following beneficial effects:
[0014] The utility model solves the problem that the outlet of the high-speed continuous spinning water washing pipeline has no exhaust gas, which easily causes the water in the washing pool to splash out due to the conveying impact caused by bubbles by arranging a conveying chamber, a feeding chamber and a transfer chamber. The cleaning water is conveyed to the feeding chamber through an input pipe, and the water is conveyed to the conveying chamber through a conveying frame, and is connected to the joint on the output water pipeline through two connecting pieces. At this time, the cleaning water in the conveying chamber and the feeding chamber is conveyed to the output water pipeline through the output pipe. In the conveying process, the bubbles of the cleaning water float in the conveying chamber and the feeding chamber. After floating, the bubbles are conveyed to the conveying chamber, and the top height of the conveying chamber is higher than the top height of the feeding chamber. The bubbles rise in the conveying chamber to the exhaust pipe, and are conveyed to the transfer chamber through the exhaust pipe, which effectively prevents the bubbles from entering the water outlet position of the high-speed continuous spinning water washing pipeline, ensures the continuity of water conveyance, and prevents the splashing of water caused by the bubble section in the water conveyance.
[0015] The utility model solves the problem of inconvenient determination of whether high-speed continuous spinning water washing pipeline needs to be vented and whether the venting is completed by arranging a conveying chamber, a feeding chamber and a transfer chamber. When the gas collected in the conveying chamber is conveyed to the transfer chamber through the exhaust pipe, the liquid level in the transfer chamber gradually decreases, and the position of the float on the movable rod is observed through the observation window on the transfer chamber. The float drops to the lower part of the transfer chamber. After the gas content in the transfer chamber increases to a certain level, the electric control valve 2 is opened. At this time, the water in the conveying chamber is conveyed to the transfer chamber through the exhaust pipe, and then the air is pushed up to the air outlet pipe in the transfer chamber. The air is discharged through the air outlet pipe, and the position of the float is observed through the observation window. When the float rises to the upper part of the transfer chamber, the electric control valve 2 is closed to stop the venting of the air outlet pipe, so as to more conveniently determine whether the high-speed continuous spinning water washing pipeline needs to be vented and whether the venting is completed.
