[0002] In the production of viscose fiber, the task of the acid station is to continuously supply an acid bath with qualified composition and temperature to the spinning process, while ensuring the normal operation of silk production and recovering the acid bath flowing back from the spinning machine.

[0003] In the prior art, the spinning return acid enters the degassing system (vacuum suction), the degassed falling acid enters the main pipe of the bottom tank pump, a small part of the degassed falling acid is pumped into the mixing tank by a dispensing pump, and after being mixed evenly with the added sulfuric acid and zinc sulfate, it enters each bottom tank respectively. Most of the degassed falling acid is mixed with the acid discharged from the bottom tank and the evaporation return acid and then enters the bottom tank pump, and then enters the high-level tank after filtration. The degassed falling acid directly enters the main pipe; the degassed falling acid pipe is transformed, and a bottom tank is transformed into a degassing falling acid buffer tank. After the transformation, the impact caused by the degassed falling acid directly entering the main pipe can be effectively reduced. At the degassed falling acid inlet (adding a socket pipe) at the top of the bottom tank, an overflow port is opened on the side and connected to the main pipe of the bottom tank pump inlet, and an exhaust port is opened at the top and connected to the exhaust main pipe.

[0033] Embodiment 1. Please refer to Figures 1 to 14 , the present invention provides a technical solution: a device for increasing the stability of the acid bath composition, including a bottom tank 1. A receiving pipe 2 is fixedly connected to the inner bottom of the bottom tank 1. Four groups of overflow holes 3 are opened on the side surface of the bottom of the receiving pipe 2.

When the handle on one side of the magnet block 20 is toggled towards the mounting block 15 until the bottom rod 21 disengages from the limiting hole 27 and the bottom end of the bottom rod 21 is located in the top groove 25, first, the limiting of the auxiliary ring 23 is completed. The auxiliary ring 23 also drives the pressing plate 24 to fit more tightly with the sealing ring 9, strengthening the sealing performance of the sealing ring 9 and preventing the sealing effect from decreasing after the sealing ring 9 is used for a period of time. Second, the limiting of the rotating rod 28 and the holding block 29 as a whole is completed, so that the distance between the two side plates of the resisting ring 11 that are symmetrical to each other is enlarged, and the side plate fixed with the pressing plate 12 will deform to a certain extent and approach the sealing ring 9, so that the pressing plate 12 and the rubber strip 13 press the sealing ring 9 more tightly, achieving a better sealing effect. When the handle on one side of the magnet block 20 is toggled until the bottom end of the bottom rod 21 moves to the bottom of the limiting hole 27 and the top end of the limiting rod 16 disengages from the clamping groove 19, the connecting pipe 10 and the resisting ring 11 can be detached from the bottom tank 1. Finally, the sealing ring 9 is removed from one end of the resisting ring 11, and the sealing ring 9 can be replaced. The whole is convenient for replacing the sealing ring 9 and is also convenient for installing and disassembling the connecting pipe 10.

[0034] Embodiment 2. On the basis of Embodiment 1, an annular side groove 6 and a placement groove 7 are formed on the outer ring surface of the bottom groove 1. The side groove 6 and the placement groove 7 are connected through. A baffle 8 is fixedly connected at the junction of the side groove 6 and the placement groove 7. And the sealing ring 9 is located in the placement groove 7. One side of the sealing ring 9 is in contact with one side of the baffle 8. There are two groups of baffles 8, and the two groups of baffles 8 are symmetrically distributed about the center of the placement groove 7. The side groove 6 and the placement groove 7 are concentric with the overflow port 5. The abutting ring 11 is an annular plate-like structure with a "C"-shaped cross-section. The central plate of the abutting ring 11 is fixedly connected to the outer ring surface of the connecting pipe 10. One side plate of the abutting ring 11 close to the sealing ring 9 is an elastic plate. The abutting ring 11 is located on the surface of the side groove 6. A pressing plate 12 is fixedly connected to the side surface of one side plate of the abutting ring 11 close to the sealing ring 9. The pressing plate 12 is an arc-shaped plate. The pressing plate 12 is movably inserted between the outer ring surface of the sealing ring 9 and the surface of the placement groove 7. A rubber strip 13 is fixedly connected to the inner ring surface of the pressing plate 12. The rubber strip 13 is in movable contact with the outer ring surface of the sealing ring 9. There are four groups of pressing plates 12, and the four groups of pressing plates 12 are circumferentially arranged in an array about the center of the abutting ring 11. The auxiliary assembly includes a limiting rod 16, a limiting block 17, a magnet block 20, a bottom rod 21, and a rotating plate 22. An installation block 15 is integrally formed on the side surface of one side plate of the abutting ring 11 away from the sealing ring 9. The limiting rod 16 is a circular rod. The limiting block 17 is fixed on the outer ring surface of the limiting rod 16. The limiting block 17 is a pentagonal plate-like structure. A pentagonal limiting groove 18 is formed on the surface of the installation block 15. The limiting block 17 is movably inserted into the limiting groove 18. The magnet block 20 is fixedly connected to the bottom surface of the limiting rod 16. The top of the limiting rod 16 is movably inserted into a card slot 19. The card slot 19 is formed on the outer ring surface of the side groove 6. A magnet 33 is installed on one side plate of the abutting ring 11 close to the magnet block 20. The magnet block 20 and the magnet 33 attract each other.

[0035] In the present invention, the sealing ring 9 is sleeved on the outer ring surface of the connecting pipe 10, and the sealing ring 9 is placed in the placement groove 7. The baffle 8 limits the sealing ring 9 to prevent the sealing ring 9 from disengaging from the placement groove 7. At the same time, one end of the connecting pipe 10 is movably inserted into the overflow port 5. At this time, the abutting ring 11 is located in the side groove 6, and the rubber strip 13 is in contact with the outer ring surface of the sealing ring 9, realizing the extrusion of the sealing ring 9, so that the inner ring surface of the sealing ring 9 is fully in contact with the outer ring surface of the connecting pipe 10, achieving a better sealing effect; the rubber strip 13 can fill the gap between the pressing plate 12 and the sealing ring 9 to ensure full contact between the sealing ring 9 and the connecting pipe 10.

[0036] Embodiment 3. On the basis of Embodiment 2, the bottom rod 21 and the integral rod 22 are circular rods. The bottom rod 21 is fixed to the bottom of the magnet block 20. The bottom rod 21 is a circular rod and is fixed to the bottom of the magnet block 20. The bottom rod 21 passes through the top groove 25 and is movably inserted into the limiting hole 27. The top groove 25 is a circular cylindrical groove. The limiting hole 27 is opened on the surface of the integral plate 26. The rotating plate 22 is rotatably connected to the outer ring surface of the bottom rod 21. Five groups of limiting holes 27 are opened. The multiple groups of limiting holes 27 are circumferentially arrayed about the center of the limiting rod 26. And five groups of limiting holes 27 are opened on the other two adjacent surfaces of the integral plate 26. The bottom surface of the auxiliary ring 23 is fixedly connected with an auxiliary plate 34. The auxiliary plate 34 is an "L"-shaped plate structure. Two groups of sliding plates 35 are symmetrically slidably connected to one side of the auxiliary plate 34. And the rotating plate 22 is located between the two groups of sliding plates 35. One side of the auxiliary ring 23 close to the abutting ring 11 is fixedly connected with an abutting plate 24. The abutting plate 24 is an arc-shaped plate structure. One end of the abutting plate 24 passes through the through hole 31 and contacts one side of the sealing ring 9. The through hole 31 is opened on the side surfaces of the two symmetric side plates of the abutting ring 11. Two groups of abutting plates 24 are fixed. The two groups of abutting plates 24 are symmetrically distributed about the center of the auxiliary ring 23.

[0037] In the present invention, the top end of the limiting rod 16 is movably inserted into the clamping groove 19, so that the connection pipe 10 and the abutting ring 11 as a whole can be limited. The bottom rod 21 is movably inserted into the limiting hole 27, and the bottom rod 21 can limit the auxiliary ring 23. At the same time, the abutting plate 24 on one side of the auxiliary ring 23 presses the sealing ring 9, ensuring that one side of the sealing ring 9 can be fully attached to one side of the placement groove 7, and ensuring good sealing at the connection between the connection pipe 10 and the overflow port 5; After the sealing ring 9 has been used for a period of time, pull the handle on one side of the magnet block 20 in the direction close to the mounting block 15, so that the bottom rod 21 disengages from the limiting hole 27 until the bottom end of the bottom rod 21 is located in the top groove 25, and the limiting block 17 also disengages from the limiting groove 18. Then rotate the magnet block 20 so that the limiting block 17 rotates 72 degrees. Because the bottom rod 21 and the magnet block 20 are not coaxial, the rotation of the bottom rod 21 will drive the rotating plate 22 to hold the auxiliary plate 34 (in the direction close to the abutting ring 11). The held auxiliary plate 34 will drive the auxiliary ring 23 to move a certain distance in the direction close to the abutting ring 11 (please refer to Figure 14, a resilient plate is fixedly connected between one side of the sliding plate 35 and one side of the groove for its sliding. The resilient plate applies a holding effect on the sliding plate 35, which can ensure that the two sets of sliding plates 35 can always clamp the rotating plate 22 therebetween. When the bottom rod 21 rotates, the rotating plate 22 can push against the auxiliary plate 34). The bottom end of the bottom rod 21 rotates in the top groove 25. Finally, the handle on one side of the magnet block 20 is toggled to insert the limiting block 17 back into the limiting groove 18. At this time, the side surface of the limiting block 17 fits with the side surface of the limiting groove 18 in an adapted state. The bottom end of the bottom rod 21 is also inserted into a corresponding set of limiting holes 27 to complete the limiting of the auxiliary ring 23. After completing the limiting of the auxiliary ring 23, the handle on one side of the magnet block 20 is released, and the magnet block 20 will return to its reset state. The reset magnet block 20 is attracted to the magnet 33. Therefore, the entire limiting rod 16 will not move easily; and the auxiliary ring 23 after moving a certain distance also drives the abutting plate 24 to fit more tightly with the sealing ring 9, strengthening the sealing performance of the sealing ring 9 and preventing the sealing effect of the sealing ring 9 from decreasing after being used for a period of time.

[0038] Embodiment 4, on the basis of Embodiment 3, the holding member includes a holding plate 32. The holding plate 32 is in an arc-shaped plate structure. A positioning rod 14 is fixedly connected to the central plate surface of the abutting ring 11. The positioning rod 14 is located between the two side plates of the abutting ring 11. The holding plate 32 is sleeved on the outer ring surface of the positioning rod 14, and the side surface of the holding plate 32 is in movable contact with the two side plates of the abutting ring 11. The limiting assembly includes a rotating rod 28, a holding block 29, a connecting rod 30, and an integral plate 26. The rotating rod 28 is in a "T"-shaped rod. The integral plate 26 is fixedly connected to the outer ring surface of the rotating rod 28. The integral plate 26 is rotatably connected to the side surface of the auxiliary ring 23. One end of the rotating rod 28 is rotatably connected to one side plate of the abutting ring 11 close to the auxiliary ring 23. The holding block 29 is in a "T"-shaped plate. The holding block 29 is fixed at one end of the rotating rod 28. The lengths of the three side plates of the holding block 29 are not equal. One side plate of the holding block 29 is in movable contact with the inner ring surface of the holding plate 32. There are two sets of holding blocks 29 fixed. The connecting rod 30 is fixed between the two sets of holding blocks 29. The connecting rod 30 penetrates through the positioning rod 14.

[0039] In the present invention, when the handle on one side of the magnet block 20 is toggled towards the mounting block 15 until the bottom end of the bottom rod 21 disengages from the limiting hole 27 and reaches the top groove 25, the rotating rod 28 is rotated by ninety degrees to drive the integral plate 26 to rotate. Then, the handle on one side of the magnet block 20 is toggled again to insert the bottom end of the bottom rod 21 into the corresponding limiting hole 27 on the adjacent surface of the integral plate 26, thereby completing the limitation of the entire rotating rod 28 and the holding block 29. After the limitation is completed, the handle on one side of the magnet 20 is released, and the magnet 20 returns to its original state. Since the length of each side plate of the holding block 29 is unequal, when the rotating rod 28 rotates to drive the longer side plate of the holding block 29 to rotate, the holding plate 32 will move along the top direction of the positioning rod 14, thereby expanding the distance between the two symmetric side plates of the abutting ring 11. The side plate fixed with the pressing plate 12 will undergo a certain deformation and approach the sealing ring 9, so that the pressing plate 12 and the rubber strip 13 squeeze the sealing ring 9 more tightly, achieving a better sealing effect; The handle on one side of the magnet block 20 is toggled until the bottom end of the bottom rod 21 moves to the bottom of the limiting hole 27. Since the limiting hole 27 is a through hole, when the limitation of the rotating rod 28 is completed, only a short distance of the bottom end of the bottom rod 21 is inserted into the limiting hole 27. Therefore, after the top end of the limiting rod 16 disengages from the card slot 19, the remaining space in the limiting hole 27 is sufficient to accommodate the bottom end of the bottom rod 21. After the top end of the limiting rod 16 disengages from the card slot 19, the connecting pipe 10 and the abutting ring 11 can be removed from the bottom groove 1. Finally, the sealing ring 9 is removed from one end of the abutting ring 11, and the sealing ring 9 can be replaced. The whole is convenient for replacing the sealing ring 9, and at the same time convenient for disassembling the connecting pipe 10, and it is time-saving and labor-saving.

[0040] Working principle and usage process of the present invention: The top end of the limit rod 16 is movably inserted into the card slot 19, so as to limit the connection pipe 10 and the abutting ring 11 as a whole. The bottom rod 21 is movably inserted into the limit hole 27, and the bottom rod 21 can limit the auxiliary ring 23. At the same time, the abutting plate 24 on one side of the auxiliary ring 23 presses the sealing ring 9, ensuring that one side of the sealing ring 9 can fully fit with one side of the placement groove 7, and ensuring good sealing at the connection between the connection pipe 10 and the overflow port 5; After the sealing ring 9 has been used for a period of time, move the handle on one side of the magnet block 20 towards the mounting block 15, so that the bottom rod 21 disengages from the limit hole 27 until the bottom end of the bottom rod 21 is located in the top groove 25. At this time, the limit block 17 also disengages from the limit groove 18. Then rotate the magnet block 20 to make the limit block 17 rotate 72 degrees. Because the bottom rod 21 and the magnet block 20 are not coaxial, the rotation of the bottom rod 21 will drive the rotating plate 22 to hold the auxiliary plate 34 (towards the direction of the abutting ring 11). The held auxiliary plate 34 will drive the auxiliary ring 23 to move a certain distance towards the direction of the abutting ring 11. The bottom end of the bottom rod 21 rotates in the top groove 25. Finally, move the handle on one side of the magnet block 20 to insert the limit block 17 back into the limit groove 18. At this time, the side surface of the limit block 17 fits with the side surface of the limit groove 18 in an adapted state, and the bottom end of the bottom rod 21 is also inserted into a corresponding set of limit holes 27 to complete the limitation of the auxiliary ring 23; After moving a certain distance, the auxiliary ring 23 also drives the abutting plate 24 to fit more tightly with the sealing ring 9, strengthening the sealing performance of the sealing ring 9 and preventing the sealing effect from decreasing after the sealing ring 9 has been used for a period of time; Move the handle on one side of the magnet block 20 towards the mounting block 15, so that the bottom rod 21 disengages from the limit hole 27 until the bottom end of the bottom rod 21 is located in the top groove 25. Then rotate the rotating rod 28 by 90 degrees to drive the integral plate 26 to rotate. Then move the handle on one side of the magnet block 20 to insert the bottom end of the bottom rod 21 into the limit hole 27 corresponding to the adjacent surface of the integral plate 26, and the limitation of the rotating rod 28 and the holding block 29 as a whole can be completed. Due to the unequal length of each side plate of the holding block 29 itself, when the rotating rod 28 rotates to drive the longer side plate of the holding block 29 to rotate, the holding plate 32 will move along the top direction of the positioning rod 14, so that the distance between the two side plates of the abutting ring 11 that are symmetrical to each other expands, and the side plate fixed with the pressing plate 12 will deform to a certain extent and move closer to the sealing ring 9, so that the pressing plate 12 and the rubber strip 13 press the sealing ring 9 more tightly, achieving a better sealing effect; Move the handle on one side of the magnet block 20 until the bottom end of the bottom rod 21 moves to the bottom of the limit hole 27. Because the limit hole 27 is a through hole, when the limitation of the rotating rod 28 is completed, only a short distance of the bottom end of the bottom rod 21 is inserted into the limit hole 27. Therefore, after the top end of the limit rod 16 disengages from the card slot 19, the remaining space in the limit hole 27 is sufficient to accommodate the bottom end of the bottom rod 21;After the top end of the limit rod 16 disengages from the card slot 19, the connecting pipe 10 and the abutting ring 11 can be removed from the bottom groove 1. Finally, the sealing ring 9 is removed from one end of the abutting ring 11, and the sealing ring 9 can be replaced. Overall, it is convenient to replace the sealing ring 9, and at the same time, it is convenient to disassemble the connecting pipe 10, which is time-saving and labor-saving. The sealing ring 9 is sleeved on the outer ring surface of the connecting pipe 10, and the sealing ring 9 is placed in the placement groove 7. The baffle 8 limits the sealing ring 9 to prevent the sealing ring 9 from disengaging from the placement groove 7. At the same time, one end of the connecting pipe 10 is movably inserted into the overflow port 5. At this time, the abutting ring 11 is located in the side groove 6, and the rubber strip 13 is in contact with the outer ring surface of the sealing ring 9, realizing the extrusion of the sealing ring 9, so that the inner ring surface of the sealing ring 9 is fully in contact with the outer ring surface of the connecting pipe 10, achieving a better sealing effect. The rubber strip 13 can fill the gap between the pressing plate 12 and the sealing ring 9 to ensure full contact between the sealing ring 9 and the connecting pipe 10.;
