Description

Technical Field

[0001] This invention belongs to the field of acid bath technology, specifically relating to a device for increasing the stability of acid bath composition. Background Technology

[0002] In viscose fiber production, the acid station's task is to continuously supply acid baths with the correct composition and temperature to the spinning process, ensuring normal fiber production while recovering acid baths that have flowed back from the spinning machine.

[0003] In existing technology, the recycled acid from spinning enters the degassing system (vacuum suction), the degassed acid enters the bottom tank pump's acid inlet main pipe, a small portion of the degassed acid is pumped into the mixing tank by the mixing pump, and after being mixed evenly with added sulfuric acid and zinc sulfate, it enters each bottom tank separately. Most of the degassed acid is mixed with the acid from the bottom tank and the evaporated recycled acid and then enters the bottom tank pump, is filtered and enters the high-level tank, and the degassed acid directly enters the main pipe. The degassed acid pipe is modified by modifying a bottom tank as a degassed acid buffer tank. After modification, the impact caused by the degassed acid directly entering the main pipe can be effectively reduced. A degassed acid outlet (with a socket pipe) is added to the top of the bottom tank, an overflow outlet is opened on the side and connected to the bottom tank pump's inlet main pipe, and an exhaust outlet is opened at the top and connected to the exhaust main pipe.

[0032] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The top of the auxiliary component is movably inserted into the surface of the bottom groove 1, and the bottom of the auxiliary component is movably inserted into the surface of the limiting component. Move the handle on one side of the magnet block 20 towards the mounting block 15 so that the bottom rod 21 exits from the limiting hole 2.

This allows the pressure plate 12 and rubber strip 13 to 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 limiting hole 27. After the top end of the limiting rod 16 disengages from the slot 19, the connecting pipe 10 and the abutment ring 11 can be removed from the bottom groove 1. Finally, remove the sealing ring 9 from one end of the abutment ring 11 to replace the sealing ring 9. This makes it easy to replace the sealing ring 9 and also makes it easy to install and remove the connecting pipe 10.

The auxiliary assembly comprises a limit rod (16), a limit block (17), a magnet block (20), a bottom rod (21) and a rotating plate (22), a mounting block (15) is integrally formed on the side surface of the side plate of the abutment ring (11) away from the sealing ring (9), the limit rod (16) is a circular rod, the limit block (17) is fixedly arranged on the outer annular surface of the limit rod (16), the limit block (17) is a pentagonal plate-shaped structure, a pentagonal limit groove (18) is formed on the surface of the mounting block (15), the limit block (17) is movably inserted into the limit groove (18), the magnet block (20) is fixedly connected to the bottom surface of the limit rod (16), the top of the limit rod (16) is movably inserted into a clamping groove (19), the clamping groove (19) is formed on the outer annular surface of the edge groove (6), a magnet (33) is mounted on the side plate of the abutment ring (11) close to the magnet block (20), and 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 annular surface of the connecting pipe (10), and the sealing ring (9) is placed in the accommodating groove (7), the baffle plates (8) limit the sealing ring (9) to prevent the sealing ring (9) from detaching from the accommodating groove (7). Meanwhile, one end of the connecting pipe (10) is movably inserted into the overflow port (5), at this time, the abutment ring (11) is located in the edge groove (6), and the rubber strip (13) is in contact with the outer annular surface of the sealing ring (9), so as to realize extrusion on the sealing ring (9), so that the inner annular surface of the sealing ring (9) is fully in contact with the outer annular surface of the connecting pipe (10), achieving a good sealing effect; the rubber strip (13) can fill the gap between the pressure plate (12) and the sealing ring (9), ensuring sufficient contact between the sealing ring (9) and the connecting pipe (10).

[0036] In Example 3, based on Example 2, the bottom rod 21 and the integrated rod 22 are circular rods. The bottom rod 21 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 integrated plate 26. The rotating plate 22 is rotatably connected to the outer ring surface of the bottom rod 21. Five sets of limiting holes 27 are opened. The multiple sets of limiting holes 27 are distributed in a circumferential array about the center of the limiting rod 26, and five sets are opened on the other two adjacent surfaces of the integrated plate 26. The bottom surface of the auxiliary ring 23 is fixedly connected to the limiting hole 27 and the auxiliary plate 34. The auxiliary plate 34 has an "L" shaped plate structure. Two sets 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 sets of sliding plates 35. The side of the auxiliary ring 23 near the abutment ring 11 is fixedly connected to the abutment plate 24. The abutment plate 24 has an arc-shaped plate structure. One end of the abutment 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 of the two symmetrical plates of the abutment ring 11. There are two sets of abutment plates 24, and the two sets of abutment plates 24 are symmetrically distributed about the center of the auxiliary ring 23.

[0037] In this invention, the top end of the limiting rod 16 is movably inserted into the slot 19, which can limit the connection tube 10 and the abutment ring 11 as a whole. The bottom rod 21 is movably inserted into the limiting hole 27, which can limit the auxiliary ring 23. At the same time, the abutment plate 24 on one side of the auxiliary ring 23 presses against 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 tube 10 and the overflow port 5. After the sealing ring 9 has been used for a period of time, move the handle on the side of the magnet block 20 towards the mounting block 15 to disengage the bottom rod 21 from the limiting hole 27 until the bottom end of the bottom rod 21 is in the top groove 25. At this point, the limiting block 17 will also disengage from the limiting groove 18. Then, rotate the magnet block 20 to rotate the limiting block 17 72 degrees. Because the bottom rod 21 and the magnet block 20 are not on the same axis, the rotation of the bottom rod 21 will cause the rotating plate 22 to push against the auxiliary plate 34 (towards the abutment ring 11). The pushed auxiliary plate 34 will cause the auxiliary ring 23 to move a certain distance towards the abutment ring 11 (please refer to...). Figure 14A spring plate is fixedly connected between one side of the sliding plate 35 and the side of the groove for sliding. The spring plate supports the sliding plate 35, ensuring that the two sets of sliding plates 35 can always clamp the rotating plate 22 between them, ensuring that the rotating plate 22 can support the auxiliary plate 34 when the bottom rod 21 rotates. 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 turned to make the limiting block 17 re-insert into the limiting groove 18. At this time, the side of the limiting block 17 fits the side of the limiting groove 18 in a matching state. The bottom rod 21 The bottom end is also inserted into a corresponding set of limiting holes 27 to limit the auxiliary ring 23. After the auxiliary ring 23 is limited, the handle on one side of the magnet block 20 is released, and the magnet block 20 will be in a reset state. The magnet block 20 in the reset state is attracted to the magnet 33, so the limiting rod 16 will not move easily. The auxiliary ring 23 after moving a certain distance also causes the abutment 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 a period of use.

[0038] In Embodiment 4, based on Embodiment 3, the supporting member includes a supporting plate 32, which has an arc-shaped plate structure. A positioning rod 14 is fixedly connected to the surface of the central plate of the abutment ring 11. The positioning rod 14 is located between the two side plates of the abutment ring 11. The supporting plate 32 is sleeved on the outer ring surface of the positioning rod 14, and the side surface of the supporting plate 32 is in movable contact with the two side plates of the abutment ring 11. The limiting component includes a rotating rod 28, a supporting block 29, a connecting rod 30, and an integral plate 26. The rotating rod 28 is a "T"-shaped rod, and the integral plate 26 is fixedly connected to... The outer ring surface of the rotating rod 28 is connected to the outer ring surface, the integral plate 26 is rotatably connected to the side of the auxiliary ring 23, one end of the rotating rod 28 is rotatably connected to the side plate of the abutment ring 11 near the auxiliary ring 23, the top holding block 29 is a "T" shaped plate, the top holding block 29 is fixed to one end of the rotating rod 28, the three side plates of the top holding block 29 are of different lengths, one side plate of the top holding block 29 is in movable contact with the inner ring surface of the top holding plate 32, there are two sets of top holding blocks 29, the connecting rod 30 is fixed between the two sets of top holding blocks 29, and the connecting rod 30 passes through the positioning rod 14.

[0039] In this invention, by moving the handle on one side of the magnet block 20 towards the mounting block 15, the bottom rod 21 is disengaged from the limiting hole 27 until the bottom end of the bottom rod 21 is located in the top groove 25. Then, the rotating rod 28 is rotated 90 degrees to rotate the integrated plate 26. Next, the handle on one side of the magnet block 20 is moved to insert the bottom end of the bottom rod 21 into the corresponding limiting hole 27 on the adjacent surface of the integrated plate 26. This completes the overall limiting of the rotating rod 28 and the top holding block 29. After the limiting is completed, the handle on one side of the magnet 20 is released. When the magnet 20 is in the reset state, and the length of each side plate of the top holding block 29 is different, when the rotating rod 28 rotates and drives the longer side plate of the top holding block 29 to rotate, the top holding plate 32 will move along the top direction of the positioning rod 14, thereby increasing the distance between the two symmetrical side plates of the abutment ring 11. The side plate with the pressure plate 12 fixed will undergo a certain deformation and move closer to the sealing ring 9, thereby making the pressure plate 12 and the rubber strip 13 squeeze 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 limiting hole 27. Since the limiting hole 27 is a through hole, when the rotating rod 28 is limited, the bottom end of the bottom rod 21 only needs a short distance to be inserted into the limiting hole 27. Therefore, after the top end of the limiting rod 16 is disengaged from the 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 is disengaged from the slot 19, the connecting tube 10 and the abutment ring 11 can be removed from the bottom groove 1. Finally, remove the sealing ring 9 from one end of the abutment ring 11 to replace the sealing ring 9. The whole process is convenient for replacing the sealing ring 9 and for disassembling the connecting tube 10, saving time and effort.

[0040] The working principle and usage process of this invention: The top end of the limiting rod 16 is movably inserted into the slot 19, which can limit the connection tube 10 and the abutment ring 11 as a whole. The bottom rod 21 is movably inserted into the limiting hole 27, which can limit the auxiliary ring 23. At the same time, the abutment plate 24 on one side of the auxiliary ring 23 presses against the sealing ring 9, ensuring that one side of the sealing ring 9 can fully fit with one side of the placement groove 7, ensuring good sealing at the connection between the connection tube 10 and the overflow port 5. After the sealing ring 9 has been used for a period of time, the handle on the side of the magnet block 20 is moved towards the mounting block 15, so that the bottom rod 21 is disengaged from the limiting hole 27 until the bottom end of the bottom rod 21 is located in the top groove 25. At this time, the limiting block 17 also moves out of the limiting hole 27. After disengaging from the slot 18, the magnet 20 is rotated, causing the limiting block 17 to rotate 72 degrees. Because the bottom rod 21 and the magnet 20 are not on the same axis, the rotation of the bottom rod 21 will cause the rotating plate 22 to push against the auxiliary plate 34 (towards the abutment ring 11). The pushed auxiliary plate 34 will cause the auxiliary ring 23 to move a certain distance towards the abutment ring 11. The bottom end of the bottom rod 21 rotates in the top slot 25. Finally, the handle on one side of the magnet 20 is turned to make the limiting block 17 re-insert into the limiting slot 18. At this time, the side of the limiting block 17 fits against the side of the limiting slot 18, and the bottom end of the bottom rod 21 is also inserted into the corresponding set of limiting holes 27, completing the limiting of the auxiliary ring 23; and after moving a certain distance The auxiliary ring 23 also causes the abutment 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 a period of use. By moving the handle on one side of the magnet block 20 closer to the mounting block 15, the bottom rod 21 is disengaged from the limiting hole 27 until the bottom end of the bottom rod 21 is located in the top groove 25. Then, rotating the rotating rod 28 ninety degrees causes the integrated plate 26 to rotate. Next, moving the handle on one side of the magnet block 20 causes the bottom end of the bottom rod 21 to insert into the corresponding limiting hole 27 on the adjacent surface of the integrated plate 26. This completes the overall limiting of the rotating rod 28 and the top holding block 29. Because the length of each side plate of the top holding block 29 is unequal, the rotation of the rotating rod 28 causes the longer side plate of the top holding block 29 to move... When rotating, the top plate 32 moves along the top of the positioning rod 14, thereby increasing the distance between the two symmetrical side plates of the abutment ring 11. The side plate with the pressure plate 12 fixed will deform to move closer to the sealing ring 9, thereby making the pressure 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 limiting hole 27. Since the limiting hole 27 is a through hole, when the rotation rod 28 is limited, the bottom end of the bottom rod 21 is inserted into the limiting hole 27 only a short distance away. Therefore, after the top end of the limiting rod 16 is disengaged from the 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 of the limiting rod 16 disengages from the slot 19, the connecting pipe 10 and the abutment ring 11 can be removed from the bottom groove 1. Finally, the sealing ring 9 can be removed from one end of the abutment ring 11 for replacement. This makes it easy to replace the sealing ring 9 and disassemble the connecting pipe 10, saving time and effort. The sealing ring 9 is fitted onto the outer ring surface of the connecting pipe 10 and placed in the placement groove 7. The baffle 8 limits the sealing ring 9 to prevent it from detaching 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 abutment 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, compressing the sealing ring 9 and ensuring that the inner ring surface of the sealing ring 9 is in full 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 pressure plate 12 and the sealing ring 9, ensuring that the sealing ring 9 and the connecting pipe 10 are in full contact.
