Description

Technical Field

[0001] This utility model relates to the technical field of rinsing in the chemical fiber industry, specifically an overflow rinsing complete set of equipment, which is particularly suitable for viscose, Lyocell and vinylon staple fiber refining machines and carbon fiber felt rinsing machines. Background Technology

[0002] In the chemical fiber industry, the post-processing of viscose, Lyocell, and vinylon staple fibers is a crucial step before the finished fiber product, with the refining machine being one of the key unit machines. The refining machine is used to process the chopped staple fibers through washing, desulfurization, bleaching, and oiling, giving the fibers good whiteness and spinnability. Carbon fiber felt pre-oxidation is another important step in carbon fiber felt processing, with the rinsing machine being one of the key unit machines. The rinsing machine is used to remove impurities from the surface of the raw carbon fiber felt and precipitates such as metal salts from the pre-oxidized felt through solvent cleaning. Both the refining machine and the rinsing machine contain a vital component—the rinsing and washing device. The rinsing and washing device performs the washing, bleaching, and oiling processes on the fiber materials, and its effectiveness directly affects the physical and mechanical properties of the finished product and the quality of the finished fiber.

[0003] Currently, existing rinsing devices can be broadly categorized into two types. The first type involves a rinsing support mounted side-mounted on the rinsing machine frame. The front-to-back position of the rinsing device cannot be adjusted, and its height can only be fine-tuned. Furthermore, due to structural limitations, online adjustment is not possible, resulting in uneven rinsing water distribution. The second type simply involves opening rinsing holes in a circular tube or using nozzles for rinsing. This also results in uneven rinsing water distribution and significant impact on the material layer. In summary, current rinsing devices, due to structural limitations, cannot adjust the rinsing position and height online, making operation and maintenance inconvenient. More importantly, the uneven distribution of the rinsing solution and the significant impact on the material layer not only lead to poor rinsing results but also damage the material layer, directly affecting the physical and mechanical properties of the finished product and the quality of the finished fiber. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the existing technology by providing an overflow-type rinsing device. This invention allows the rinsing solution to be evenly rinsed onto the material layer after two overflows, completing the solvent cleaning of the material. This significantly reduces the impact of the rinsing solution on the material layer, minimizing its impact on uniformity, preventing damage to the material layer, and improving the fiber rinsing effect. Furthermore, this invention allows for online adjustment of the rinsing position, height, and width, greatly improving the uniformity of the rinsing solution distribution, enhancing the rinsing effect, ensuring the quality of the finished fiber, and increasing the convenience and versatility of the rinsing operation. Simultaneously, this invention allows for convenient and quick removal of residual impurities from the rinsing solution, and easy and quick disassembly of the rinsing tank for maintenance and upkeep. It also boasts advantages such as ease of operation, convenient use, and easy maintenance.

[0005] The objective of this utility model can be achieved through the following technical solutions: This utility model discloses an overflow-type rinsing assembly comprising several rinsing tank components arranged in parallel front to back within the process area between two sets of pressure rollers of a rinsing machine, and fixed at both ends to the rinsing machine frame by adjusting bolts. These components allow for a staggered, two-stage overflow arrangement. The rinsing liquid undergoes two deceleration and equalization processes within the rinsing tank components before overflowing down and uniformly rinsing the material layer, thus completing the solvent cleaning of the material. This significantly reduces the impact of the rinsing liquid on the material layer, minimizing its impact on the uniformity of the material layer, preventing damage and disruption to the material layer, and improving fiber quality. The rinsing effect is improved. During operation, the rinsing position, rinsing height, and rinsing width can be adjusted online. Specifically, by using adjusting bolts connected to the elongated adjusting holes on the top surface of the rinsing machine frame, the front and rear positions of the rinsing tank assembly can be adjusted, thus achieving online adjustment of the rinsing position. The adjusting bolts can also be used to adjust the height of the rinsing support and rinsing tank assembly, thus achieving online adjustment of the rinsing height. Furthermore, the adjusting bolts can be used to adjust the bottom slope of the rinsing tank assembly, facilitating the smooth discharge of residues from the rinsing solution. The rinsing tank assembly includes a rinsing bracket consisting of a U-shaped chute, support legs fixed to the bottom of both ends of the U-shaped chute, and a hanging plate fixed below the bottom of the U-shaped chute and flush with the side wall; a rinsing tank embedded in the inner cavity of the U-shaped chute; and secondary overflow components fixedly supported at the bottom of both ends of the U-shaped chute along its length and attached to the side walls of the U-shaped chute. (This invention utilizes rinsing tanks and secondary overflow components arranged at different heights to allow the rinsing liquid to overflow and uniformly rinse the material layer after passing through two deceleration and uniform flow stages, thereby completing the solvent cleaning of the material. This can greatly reduce the impact of the rinsing liquid on the material layer, reduce the impact on the uniformity of the material layer, avoid damage to the material layer, and improve the fiber rinsing effect.) The rinsing tank includes a quasi-rectangular structure with a sloping bottom and dovetail grooves on both sides of the open top. A liquid receiving tank (directly opposite the inlet pipe, serving as the channel for the rinsing liquid to flow from the inlet pipe into the rinsing tank) is vertically positioned within the inlet cavity of the rinsing tank base. A pressure relief plate, formed by bending and fastening pressure relief holes on its top surface, is arranged side-by-side within the rinsing tank base and connects to the bottom cavity of the receiving tank, creating three channels of different lengths. (The pressure relief plate is bent and fastened to form three channels of different lengths; the rinsing liquid is filtered through the pressure relief holes, resulting in a clean rinsing process.) The liquid overflows upwards and flows towards the dovetail section, while the rinsing liquid carrying residue flows along the inclined channel on the bottom surface to the drain end, and then is discharged from the rinsing tank through the drain valve. Positioning horizontal tie rods are spaced apart on the open end of the rinsing tank base and fixed to both side walls of the rinsing tank base (used to strengthen the connection rigidity of the open end of the rinsing tank). A drain valve is installed at the bottom of the drain end face of the rinsing tank base (opening the drain valve allows the residual rinsing liquid flowing to the drain end to be discharged from the rinsing tank in a timely manner). A handle is fixed to the drain end wall of the rinsing tank base (on one side). On the one hand, pulling the handle allows the rinsing tank to slide along its length within the U-shaped groove of the rinsing support, adjusting the overflow width of the rinsing tank online to ensure that the rinsing liquid completely covers the width of the material layer to be rinsed, avoiding any missed areas. On the other hand, pulling the handle also allows the rinsing tank to be easily and conveniently removed from the U-shaped groove of the rinsing support for easy subsequent maintenance. Several sets of gradually decreasing height support columns are fixedly installed below the sloping bottom surface of the rinsing tank base, extending longitudinally from the inlet end to the outlet end of the rinsing tank base. (The sloping bottom surface is used to support the base of the rinsing tank, ensuring the slope of the tank bottom so that the rinsing liquid carrying residue can flow smoothly to the drain end and be discharged from the rinsing tank in a timely manner); A row of overflow holes is opened at intervals along the longitudinal direction on the outer side of the dovetail groove at both ends of the upper opening of the rinsing tank base (to perform the initial overflow of the rinsing liquid, and to decelerate and uniformly flow the rinsing liquid). Each overflow hole group consists of an upper inverted trapezoidal hole, a middle oblong hole, and a bottom oblong hole (so that the rinsing liquid of different flow rates can be evenly distributed and flow stably). The secondary overflow assembly includes a rhombohedral tank with a parallelogram cross-section and an open top (used for secondary overflow of the rinsing liquid—that is, first receiving the rinsing liquid overflowing from the overflow hole group of the dovetail grooves on both sides of the open end of the upper rinsing tank base, then the received rinsing liquid slides down the sloping bottom of the rhombohedral tank to the outer wall, and then overflows down after being decelerated and uniformly distributed through the secondary overflow holes, finally uniformly rinsing the material layer to complete the solvent cleaning of the material), and several triangular support frames (used for supporting and fixing the rhombohedral tank) spaced along the longitudinal direction below the sloping bottom of the rhombohedral tank; all four side walls of the rhombohedral tank are vertically upward. The inner wall is fitted to the upper end of the side wall of the U-shaped chute. A row of secondary overflow holes is opened at intervals along the longitudinal direction on the outer wall (to allow secondary overflow of the rinsing liquid, further slow down the flow rate of the rinsing liquid, so that the rinsing liquid forms a water curtain effect, improves the uniformity of rinsing, reduces the impact of the rinsing liquid on the material layer, and reduces the impact on the uniformity of the material layer); at the corresponding connection positions of the bottom of all triangular support frames and the bottom of the hanging connecting plate, there are long slot bolt holes that can adjust the height of the secondary overflow component (the long slot bolt holes are used with bolts to further adjust the height of the secondary overflow component, so as to realize online adjustment of the rinsing height).

[0006] In this utility model, the bottom surface of the support leg seat is provided with bolt holes for installing adjusting bolts; the top surface of the washing machine frame is machined with a long slot adjustment hole for installing adjusting bolts and for adjusting the front and rear positions of the washing support and the washing tank (this utility model uses adjusting bolts in conjunction with the long slot adjustment hole on the top surface of the washing machine frame to adjust the front and rear positions of the washing tank assembly, that is, to realize online adjustment of the front and rear positions of the washing).

[0007] In this invention, the symmetry axes of the upper inverted trapezoidal hole, the middle oblong hole, and the bottom oblong hole of each overflow hole group are arranged vertically collinearly, and the cross-sections are arranged from largest to smallest as upper inverted trapezoidal hole, middle oblong hole, and bottom oblong hole (so that the rinsing liquid of different flow rates can achieve uniform distribution and stable flow).

[0008] In this invention, the lengths of the rinsing tank and the rhomboid trough are both less than the length of the U-shaped chute (ensuring smoother sliding of the rinsing tank along the inner cavity of the U-shaped chute; ensuring more stable mounting of the secondary overflow assembly on the rinsing support); at the same time, the length of the rhomboid trough is not less than the width of the felt blanket transported on the conveyor network (ensuring that the felt blanket can be completely rinsed by the rinsing liquid in the width direction, ensuring thorough solvent cleaning of the felt blanket without dead corners); the width of the conveyor network is greater than the width of the felt blanket (ensuring smooth and flat transport of the felt blanket).

[0009] The number of rinsing tank components described in this utility model is 2 to 3 sets (to ensure thorough solvent cleaning of materials without dead angles); the number of adjusting bolts in each set of rinsing tank components is 4 (stable and symmetrical, with balanced force).

[0010] The design principle of this utility model is as follows: In operation, this invention utilizes staggered rinsing tanks and a secondary overflow assembly to ensure the rinsing liquid undergoes two deceleration and equalization processes before overflowing downwards to evenly rinse the material layer, completing the solvent cleaning process. This significantly reduces the impact of the rinsing liquid on the material layer, minimizing its impact on uniformity, preventing damage to the material layer, and improving the fiber rinsing effect. More specifically, the rinsing liquid flowing from the upper inlet pipe first falls into a receiving tank built into the inner cavity of the rinsing tank substrate inlet end; then, it enters from the bottom of the cavity into three channels of different lengths formed by the bending and fastening of pressure relief plates; next, the rinsing liquid in the three channels is filtered through pressure relief holes, and the rinsing liquid containing residue flows along the inclined channels at the bottom to the drain end, and is promptly discharged from the rinsing tank through the opened drain valve, while the clean rinsing liquid overflows upwards and flows towards the dovetail section for further cleaning. The first overflow occurs when the clean rinsing solution flows down along the overflow hole group on the dovetail grooves at both ends of the open end of the rinsing tank base. The overflow hole group slows down and evens out the flow of the rinsing solution. Then, the rinsing solution flowing down from the overflow hole group falls onto the secondary overflow component below for secondary overflow. That is, the received rinsing solution slides down the sloping bottom of the rhomboid tank to the outer wall, and then overflows down again after being slowed down and evenly distributed by the secondary overflow hole. Finally, it is evenly rinsed onto the material layer to complete the solvent cleaning of the material.

[0011] This invention utilizes the combination of adjusting bolts and elongated slotted bolt holes to achieve online adjustment of the rinsing position and rinsing height. The sliding of the rinsing tank within the U-shaped chute enables online adjustment of the rinsing width. This not only significantly improves the uniformity of the rinsing solution distribution and enhances the rinsing effect, ensuring the quality of the finished fiber, but also strengthens the convenience and versatility of the rinsing operation. Furthermore, the invention employs three drainage channels formed by pressure relief plates of varying lengths, in conjunction with a drain valve, to conveniently and quickly remove residual impurities from the rinsing solution. The rinsing tank can also be easily disassembled for maintenance and upkeep via a handle. It boasts advantages such as ease of operation, convenient use, and easy maintenance.

[0012] Meanwhile, this invention allows for online adjustment of the rinsing position, rinsing height, and rinsing width during operation. This not only significantly improves the uniformity of the rinsing solution distribution and enhances the rinsing effect, ensuring the quality of the finished fiber, but also strengthens the convenience and versatility of the rinsing operation. More specifically, this invention utilizes adjusting bolts that engage with the elongated groove adjustment holes on the top surface of the rinsing machine frame to adjust the front and rear positions of the rinsing tank assembly, thus achieving online adjustment of the rinsing position. Furthermore, by using adjusting bolts and the elongated groove bolt holes at the bottom of the triangular support frame, the height of the rinsing support and rinsing tank assembly can be adjusted, achieving online adjustment of the rinsing height. Pulling the handle allows the rinsing tank to slide along its length within the U-shaped groove of the rinsing support, adjusting the overflow width of the rinsing tank online to ensure that the rinsing solution completely covers the width of the material layer to be rinsed, preventing any missed rinsing areas.

[0013] Furthermore, when this utility model requires maintenance, the rinsing tank can be easily and conveniently moved out of the U-shaped slide of the rinsing bracket simply by pulling the handle, which facilitates subsequent maintenance and has the advantages of being easy to operate, convenient to use, and easy to maintain.

[0014] The beneficial technical effects of this utility model are as follows: This invention enables the rinsing solution to be evenly rinsed onto the material layer after two overflows, thus completing the solvent cleaning of the material. This significantly reduces the impact of the rinsing solution on the material layer, minimizing its impact on uniformity and preventing damage to the material layer, thereby improving the fiber rinsing effect. Furthermore, this invention allows for online adjustment of the rinsing position, height, and width, greatly improving the uniformity of the rinsing solution distribution, enhancing the rinsing effect, ensuring the quality of the finished fiber, and increasing the convenience and versatility of the rinsing operation. Simultaneously, this invention allows for the convenient and quick removal of residual impurities from the rinsing solution, and the rinsing tank can be easily removed for maintenance and upkeep via a handle. It also boasts advantages such as ease of operation, convenient use, and easy maintenance. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-6 As shown, this utility model discloses an overflow-type rinsing assembly comprising several rinsing tank components A arranged in parallel front to back within the process area between two sets of pressure rollers 6 of the rinsing machine, and fixed at both ends to the frame 5 of the rinsing machine via adjusting bolts 4. These components enable a staggered, two-stage overflow arrangement. The rinsing liquid undergoes two deceleration and equalization processes within the rinsing tank components A before overflowing down and uniformly rinsing the material layer, thus completing the solvent cleaning of the material. This significantly reduces the impact of the rinsing liquid on the material layer, minimizing its impact on the uniformity of the material layer and avoiding... This invention avoids damage to the material layer and improves fiber washing effect. The adjusting bolt 4, used in conjunction with the elongated groove adjusting hole 5-1 on the top surface of the washing machine frame 5, allows for adjustment of the front and rear positions of the washing tank assembly A, enabling online adjustment of the front and rear positions. The adjusting bolt 4 also allows for adjustment of the height of the washing support 3 and the washing tank assembly A, enabling online adjustment of the washing height. Furthermore, the adjusting bolt 4 can be used to adjust the bottom slope of the washing tank assembly A, facilitating the smooth discharge of residues from the washing solution. The rinsing tank assembly A includes a rinsing bracket 3 consisting of a U-shaped chute 3-1, support legs 3-2 fixed at the bottom of both ends of the U-shaped chute, and a hanging connecting plate 3-3 fixed below the bottom of the U-shaped chute 3-1 and flush with the side wall; a rinsing tank 1 embedded in the inner cavity of the U-shaped chute; and a secondary overflow assembly 2 fixedly supported at the bottom of both ends of the U-shaped chute along its length and attached to the side walls of the U-shaped chute. (This utility model utilizes the staggered arrangement of rinsing tanks and secondary overflow assembly to allow the rinsing liquid to undergo two deceleration and uniform flow processes before overflowing down to uniformly rinse the material layer, thus completing the solvent cleaning of the material. This can greatly reduce the impact of the rinsing liquid on the material layer, reduce the impact on the uniformity of the material layer, avoid damage and destruction of the material layer, and improve the fiber rinsing effect.) The rinsing tank 1 includes a rinsing tank base 1-1 with a rectangular parallelepiped structure, a sloping bottom, and dovetail grooves on both sides of the open top. A liquid receiving tank 1-2 is vertically installed in the inner cavity of the inlet end of the rinsing tank base (directly opposite the liquid inlet pipe, serving as the channel for the rinsing liquid to flow out of the liquid inlet pipe and into the rinsing tank 1). A pressure relief hole 1-3-1 is opened on the top surface. After being bent, the pressure relief plate 1-3 is bent and fastened side by side in the inner cavity of the rinsing tank base and connected to the bottom cavity of the liquid receiving tank to form three channels of different lengths. (The pressure relief plate 1-3 is bent and fastened to form three channels of different lengths; after the rinsing liquid is filtered through the pressure relief hole 1-3-1, the clean rinsing liquid overflows upwards.) The outflow overflows towards the dovetail section, while the rinsing liquid carrying residue flows along the inclined channel on the bottom surface to the drain end, and is then discharged from the rinsing tank 1 through the drain valve 1-5. Positioning horizontal tie rods 1-4 are spaced apart on the open end of the rinsing tank base and fixed to the side walls of the rinsing tank base (used to strengthen the connection rigidity of the open end of the rinsing tank 1). A drain valve 1-5 is installed at the bottom of the drain end face of the rinsing tank base (opening the drain valve 1-5 allows the residual rinsing liquid flowing to the drain end to be discharged from the rinsing tank 1 in a timely manner). A handle 1-6 is fixed to the drain end wall of the rinsing tank base 1-1 (on the one hand, by pulling the handle 1-...). 6 can drive the rinsing tank 1 to slide along the length direction within the U-shaped slide 3-1 of the rinsing support 3, and adjust the overflow width of the rinsing tank 1 online to ensure that the rinsing liquid can completely cover the width of the material layer to be rinsed, avoiding the formation of rinsing leakage areas; on the other hand, by pulling the handle 1-6, the rinsing tank 1 can be easily and conveniently moved out of the U-shaped slide 3-1 of the rinsing support 3 for subsequent maintenance), and is fixedly supported below the sloping bottom surface of the rinsing tank base 1-1, and is provided with several sets of gradually decreasing height support columns 1-7 (used to support the rinsing tank base 1-1) arranged along the longitudinal direction from the inlet end to the drain end of the rinsing tank base 1-1. The sloping bottom ensures the slope of the bottom of the rinsing tank base 1-1, facilitating the smooth flow of the rinsing liquid carrying residues to the drain end, and thus timely discharge from the rinsing tank 1); an overflow hole group 1-1-1 is opened at intervals along the longitudinal direction on the outer side of the dovetail groove at both ends of the upper open end of the rinsing tank base 1-1 (to perform the initial overflow of the rinsing liquid, and to slow down and uniformly flow the rinsing liquid). Each overflow hole group 1-1-1 consists of an upper inverted trapezoidal hole 1-1-1-1, a middle oblong hole 1-1-1-2, and a bottom oblong hole 1-1-1-3 (so that rinsing liquids of different flow rates can achieve uniform distribution and stable flow). The secondary overflow assembly 2 includes a rhombohedral tank 2-1 with a parallelogram cross-section and an open top (used for secondary overflow of the rinsing liquid—that is, first receiving the rinsing liquid overflowing from the overflow hole group 1-1-1 of the dovetail grooves on both sides of the open top of the upper rinsing tank base 1-1, then the received rinsing liquid slides down the sloping bottom of the rhombohedral tank 2-1 to the outer wall, and then overflows down after being decelerated and uniformly distributed through the secondary overflow hole 2-1-1, finally uniformly rinsing the material layer to complete the solvent cleaning of the material), and several triangular support frames 2-2 (used for supporting and fixing the rhombohedral tank 2-1) spaced along the longitudinal direction below the sloping bottom of the rhombohedral tank; the four side walls of the rhombohedral tank 2-1 are all vertically oriented The inner sidewall is attached to the upper end of the sidewall of the U-shaped chute 3-1. A row of secondary overflow holes 2-1-1 is opened at intervals along the longitudinal direction on the outer sidewall (to allow secondary overflow of the rinsing liquid, further slow down the flow rate of the rinsing liquid, so that the rinsing liquid forms a water curtain effect, improves the uniformity of rinsing, reduces the impact of the rinsing liquid on the material layer, and reduces the impact on the uniformity of the material layer). At the corresponding connection positions of the lower bottom of all triangular support frames 2-2 and the lower bottom of the hanging connecting plate 3-3, there are long slot bolt holes 2-2-2 that can adjust the height of the secondary overflow component (the long slot bolt holes 2-2-2 are used with bolts, and can further adjust the height of the secondary overflow component 2 to realize online adjustment of the rinsing height).

[0023] In this utility model, the bottom surface of the support leg 3-2 is provided with bolt holes for installing the adjusting bolt 4; the top surface of the washing machine frame 5 is machined with a long groove adjusting hole 5-1 for installing the adjusting bolt 4 and for adjusting the front and rear positions of the washing support and the washing tank (this utility model uses the adjusting bolt 4 and the long groove adjusting hole 5-1 on the top surface of the washing machine frame 5 to adjust the front and rear positions of the washing tank assembly A, that is, to realize the online adjustment of the front and rear positions of the washing).

[0024] In this invention, the upper inverted trapezoidal hole 1-1-1-1, the middle oblong hole 1-1-1-2, and the bottom oblong hole 1-1-1-3 of each overflow hole group 1-1-1 are arranged vertically collinearly along their axes of symmetry, and their cross-sections are arranged from largest to smallest as follows: upper inverted trapezoidal hole 1-1-1-1, middle oblong hole 1-1-1-2, and bottom oblong hole 1-1-1-3 (so that the rinsing liquid of different flow rates can achieve uniform distribution and stable flow).

[0025] In this invention, the lengths of the rinsing tank 1 and the rhomboid groove 2-1 are both less than the length of the U-shaped chute 3-1 (ensuring that the rinsing tank 1 slides more smoothly along the inner cavity of the U-shaped chute 3-1; ensuring that the secondary overflow component 2 is hung more stably on the rinsing bracket 3); at the same time, the length of the rhomboid groove 2-1 is not less than the width of the felt blanket 8 transported on the conveyor network 7 (ensuring that the felt blanket 8 can be completely rinsed by the rinsing liquid in the width direction, ensuring that the solvent cleaning of the felt blanket 8 is thorough and without dead corners); the width of the conveyor network 7 is greater than the width of the felt blanket 8 (ensuring that the felt blanket 8 is transported smoothly and flat).

[0026] The number of rinsing tank components A in this utility model is 2 to 3 sets (to ensure thorough solvent cleaning of materials without dead angles); the number of adjusting bolts 4 in each set of rinsing tank components A is 4 (stable and symmetrical, with balanced force).

[0027] The specific usage of this utility model is as follows: In operation, this invention utilizes staggered rinsing tanks and a secondary overflow assembly to ensure the rinsing liquid undergoes two deceleration and equalization processes before overflowing downwards to evenly rinse the material layer, completing the solvent cleaning of the material. Specifically, the rinsing liquid flowing from the upper inlet pipe first falls into the receiving tank 1-2, which is built into the inner cavity of the inlet end of the rinsing tank base. Then, it enters from the bottom of the cavity into three channels of different lengths formed by the bending and fastening of pressure relief plates 1-3. Next, the rinsing liquid in the three channels is filtered through pressure relief holes 1-3-1. The rinsing liquid containing residue flows along the inclined channels at the bottom to the drain end and is promptly discharged from the rinsing tank 1 through the opened drain valve 1-5. The clean rinsing liquid overflows upwards to the dovetail section for the first overflow, meaning the clean rinsing liquid flows along... Overflow holes 1-1-1 on the dovetail grooves at both ends of the open end of the rinsing tank substrate 1-1 overflow down, slowing down and uniformizing the rinsing liquid. Each overflow hole group 1-1-1 consists of an upper inverted trapezoidal hole 1-1-1-1, a middle oblong hole 1-1-1-2, and a bottom oblong hole 1-1-1-3, so that rinsing liquids of different flow rates can be evenly distributed and flow stably. Then, the rinsing liquid overflowing from the overflow hole group 1-1-1 falls onto the secondary overflow component 2 below for secondary overflow. That is, the received rinsing liquid slides down the sloping bottom of the rhomboid groove 2-1 to the outer wall, and then overflows down after being slowed down and uniformized again by the secondary overflow hole 2-1-1. Finally, it is evenly rinsed onto the material layer to complete the solvent cleaning of the material. This process, with the material being uniformly rinsed through the rinsing tank and the secondary overflow component, effectively cleans the material with solvent. This significantly reduces the impact of the rinsing solution on the material layer, minimizes its impact on uniformity, prevents damage to the material layer, and improves the fiber rinsing effect.

[0028] Meanwhile, this utility model can also adjust the rinsing position, rinsing height, and rinsing width online during operation. Specifically, by using the adjusting bolt 4 in conjunction with the long groove adjusting hole 5-1 on the top surface of the rinsing machine frame 5, the front and rear positions of the rinsing tank assembly A can be adjusted, thus achieving online adjustment of the front and rear positions of the rinsing. With the help of the adjusting bolt 4 and the long groove bolt hole 2-2-2 at the bottom of the triangular support frame 2-2, the height of the rinsing support 3 and the rinsing tank assembly A can be adjusted, thus achieving online adjustment of the rinsing height. By pulling the handle 1-6, the rinsing tank 1 can slide along the length direction in the U-shaped sliding groove 3-1 of the rinsing support 3, thus adjusting the overflow width of the rinsing tank 1 online, ensuring that the rinsing liquid can completely cover the width of the material layer to be rinsed, and avoiding the formation of rinsing leakage areas.

[0029] Furthermore, when this utility model requires maintenance, simply pulling the handles 1-6 will easily and conveniently remove the rinsing tank 1 from the U-shaped slide 3-1 of the rinsing bracket 3, facilitating subsequent maintenance.
