Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of viscose filament continuous spinning equipment, and in particular relates to an acid inlet balance barrel suitable for a high-speed continuous spinning machine. Background Art
[0002] The continuous spinning machine is a high-efficiency spinning machine that integrates spinning, washing, oiling, drying and winding. It is the main machine model for viscose fiber production at present.
[0003] The main function of the acid inlet balance barrel on the continuous spinning machine is to stabilize the acid bath level in each area of the machine, thereby ensuring the same degree of reaction at each spindle position.
[0004] The acid bath enters the balance barrel from the end of the acid inlet pipe, and then flows out from the outlet after passing through the baffle in the balance barrel. By adjusting the height of the inner barrel, the liquid level of the acid bath reaction box on the machine can be adjusted. The excess acid bath overflows from the top of the inner barrel and is discharged from the overflow outlet into the acid return pipe.
[0005] When the acid bath flows upward through the baffle, the bubbles in the acid bath are discharged from the acid bath, reducing the situation of spinning ends broken due to the acid bath bubbles being transported to the spindle position. However, with the continuous development of spinning technology, the spinning speed is required to be continuously improved, and the demand for acid baths has also increased. During high-speed spinning, due to the increase in the flow rate of the acid bath, the bubbles caused by the impact of the acid bath and the bubbles in the acid bath accumulate at the bend before the outlet. Since the acid bath flows downward at this point, the bubbles cannot smoothly emerge from the acid bath liquid surface. When accumulated to a certain extent, large bubbles are formed and enter various positions with the acid bath, affecting the spinning process and even causing spinning ends to break.
[0006] The technical solution is to optimize and transform the structure of the balance barrel so that even in the high-speed spinning state, the bubbles generated by the acid bath during the flow process can still be effectively discharged from the acid bath, reducing or avoiding the acid bath bubbles entering various locations and affecting the spinning process. Utility Model Content
[0007] The utility model aims to solve the problem in the prior art that in a continuous spinning machine at high speed spinning, bubbles generated in the acid bath during the flow process still appear to be discharged from the acid bath and then enter various production areas at the back end, thus affecting the spinning forming process.
[0008] In order to achieve the above-mentioned invention object, the technical solution of the utility model is as follows:
[0009] An acid inlet balance barrel suitable for a high-speed continuous spinning machine comprises an acid bath pipe provided with a baffle, an inner tube and an outer tube, the outer tube is provided with an overflow outlet, the acid bath pipe is provided with an inlet end, an outlet end and a connecting end, the connecting end is relatively fixedly connected to the outer tube, the inner tube arranged inside the outer tube is movably connected to the connecting end, the relative height between the inner tube and the acid bath pipe is adjustable, an exhaust pipe is arranged in the acid bath pipe, the bottom of the exhaust pipe is placed between the baffle and the outlet end, and the outlet of the exhaust pipe extends out of the inner tube.
[0010] Furthermore, the exhaust pipe is fixed to the inner wall of the inner tube through a hanging piece.
[0011] Furthermore, the exhaust pipe is fixed to the inner wall of the inner tube by welding.
[0012] Furthermore, the inner cylinder and the connecting end of the acid bath tube are connected by threads.

During the upward flow of the acid bath through the baffle, the bubbles in the acid bath can be discharged from the acid bath, thereby reducing the spinning breakage caused by the acid bath bubbles being transported to the spindle position. Even in high-speed spinning, due to the increase in the flow velocity of the acid bath, the bubbles caused by the impact of the acid bath and the bubbles in the acid bath will accumulate at the baffle and the front bend of the outlet end arranged in the acid bath tube. At this time, by arranging the exhaust pipe here, it can be ensured that the acid bath bubbles can be effectively discharged from the acid bath, thereby avoiding the problem of bubbles entering various positions with the acid bath, affecting the spinning forming process, and causing the spinning breakage, thereby ensuring the product quality.
[0016] 2. In the utility model, the exhaust pipe can be fixed to the inner wall of the inner tube by a hanging part, or fixed to the inner wall of the inner tube by welding, and the entire acid inlet balance barrel device has a simple structure, which is also convenient for direct optimization on the original balance barrel, thereby realizing further utilization of the equipment and reducing the cost of the equipment.
[0017] 3. In the present invention, the connecting end of the inner cylinder and the acid bath tube is connected by a threaded connection, which is convenient for adjusting the relative height of the inner cylinder. At the same time, such a structure is also convenient for online adjustment of the relative height of the inner cylinder and the outer cylinder.

[0023] The present invention is further described in detail below in conjunction with the embodiments, but the implementation manner of the present invention is not limited thereto.
[0024] Example 1
[0025] An acid inlet balance barrel suitable for a high-speed continuous spinning machine comprises an acid bath tube 1 provided with a baffle plate 2, an inner tube 3 and an outer tube 4, the outer tube 4 is provided with an overflow outlet 4.1, the acid bath tube 1 is provided with an inlet end 1.1, an outlet end 1.2 and a connecting end 1.3, the connecting end 1.3 is relatively fixedly connected to the outer tube 4, the inner tube 3 arranged inside the outer tube 4 is movably connected to the connecting end 1.3, the relative height between the inner tube 3 and the acid bath tube 1 is adjustable, an exhaust pipe 5 is arranged in the acid bath tube 1, the bottom of the exhaust pipe 5 is placed between the baffle plate 2 and the outlet end 1.2, and the outlet of the exhaust pipe 5 extends out of the inner tube 3.
[0026] Preferably, the exhaust pipe 5 may be a round tube, a square tube or a pipe of other shapes, and the exhaust pipe 5 is slightly longer than the maximum extension length of the inner tube 3 .
[0027] This embodiment is the most basic implementation method. Figure 1 The acid bath liquid enters the acid inlet balance barrel from the inlet end 1.1 of the acid bath tube 1, and then flows out from the outlet end 1.2 after passing through the baffle plate 2 in the acid bath tube 1. The liquid level of the acid bath reaction box on the machine can be adjusted by adjusting the height of the inner tube 3. The excess acid bath liquid overflows from the top of the inner tube 3, enters the chamber formed by the inner tube 3 and the outer tube 4, and then is discharged from the overflow outlet 4.1 of the outer tube 4 to the outside of the acid inlet balance barrel.
[0028] During the upward process of the acid bath by the baffle 2, the bubbles present in the acid bath are discharged from the acid bath, which reduces the spinning breakage caused by the acid bath bubbles being transported to the spindle position. But with the continuous improvement of the spinning speed, the acid bath demand increases. During high-speed spinning, due to the increase of the acid bath flow rate, the bubbles caused by the acid bath impact and the bubbles in the acid bath are accumulated at the baffle 2 and the front bend of the outlet end 1.2 arranged in the acid bath pipe 1. By arranging the exhaust pipe 5 here, it is conducive to the acid bath bubbles to be effectively discharged from the acid bath, and it is avoided that there is too much accumulation of bubbles here, and large bubbles are formed to enter each position with the acid bath, which affects the spinning forming process and causes the problem of spinning breakage. Make the equipment under high-speed state, it can also run stably to ensure product quality.
[0029] Preferably, the exhaust pipe 5 is fixed to the inner wall of the inner tube 3 by a hanging piece, or the exhaust pipe 5 is fixed to the inner wall of the inner tube 3 by welding.
[0030] The structure of the acid inlet balance barrel is ingenious and simple, and is easy to promote and use, or to quickly optimize and transform the existing traditional balance barrel without affecting normal production and use. The optimization speed is fast, the cost is low, and the effect is obvious.
[0031] Example 2
[0032] The difference between this embodiment and embodiment 1 is that the inner cylinder 3 is connected to the connecting end 1.3 of the acid bath tube 1 through a thread 6. Figure 3 On the one hand, the relative height adjustment between the inner cylinder 3 and the outer cylinder 4 can be realized, and on the other hand, such a structure can realize online adjustment of the relative height of the inner cylinder 3 without affecting the production progress.
[0033] Example 3
[0034] This embodiment is a further optimization of the embodiment 1, and the difference is that the overflow outlet 4.1 is connected to the recovery device 8 through the acid return pipe 7 to achieve the recovery and utilization of the acid bath liquid.
[0035] refer to Figure 2 , 3, the acid bath enters the acid inlet balance barrel from the inlet end 1.1 of the acid bath tube 1, and then flows out from the outlet end 1.2 after passing through the baffle 2 in the acid bath tube 1. By adjusting the height of the inner tube 3, the liquid level of the acid bath reaction box on the machine can be adjusted. The excess acid bath overflows from the top of the inner tube 3, enters the chamber formed by the inner tube 3 and the outer tube 4, and then is discharged from the overflow outlet 4.1 of the outer tube 4, and then flows back to the recovery device 8 through the acid return pipe 7, that is, the surplus acid bath returns to the acid bath system, realizing the effective utilization of the acid bath. During the upward flow of the acid bath through the baffle 2, the bubbles in the acid bath are discharged from the acid bath, reducing the spinning breakage caused by the acid bath bubbles being transported to the spindle position. However, with the continuous improvement of the spinning speed, the demand for acid bath increases. During high-speed spinning, due to the increase in the flow rate of the acid bath, the bubbles caused by the impact of the acid bath and the bubbles in the acid bath are accumulated at the baffle 2 and the outlet end 1.2 front bend arranged in the acid bath tube 1. By arranging the exhaust pipe 5 here, it is beneficial for the acid bath bubbles to be effectively discharged from the acid bath, avoiding the excessive accumulation of bubbles here, forming large bubbles that enter various positions with the acid bath, affecting the spinning process, and causing the problem of spinning breakage.
