Description

Technical Field

[0001] This utility model relates to the field of mercerizing machine technology, and in particular to a mercerizing machine with alkali recycling. Background Technology

[0002] Mercerizing is an important process in the textile industry. It involves treating fibers such as cotton and linen with alkaline solutions to improve their luster, strength, and dyeing performance. This process facilitates the penetration and binding of dye molecules, and the alkaline solution removes burrs and impurities from the fiber surface, thus improving the smoothness and uniformity of the fibers.

[0003] According to the search, Chinese patent CN219586372U provides an alkaline solution recycling type mercerizing machine. By setting a first extrusion roller on the recycling tank and a second extrusion roller on the mounting frame, the drive mechanism drives the two to rotate synchronously in opposite directions, so that the two apply extrusion force synchronously, so that the extrusion stress on the fabric is balanced, the alkaline solution is fully extruded and recycled, and the fabric is prevented from being damaged due to excessive stress.

[0004] However, during use, it was found that the device only recovers the alkali solution by squeezing. The alkali solution after use carries a large amount of fiber impurities and other contaminants. Direct squeezing recovery can easily cause fiber impurities and contaminants to accumulate, affecting the alkali soaking effect and efficiency, and even causing damage to the fabric during the mercerizing process, which is not conducive to the recycling of alkali solution. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an alkaline solution recycling mercerizing machine. Through dual filtration treatment using an alkali-resistant nanofiltration membrane and a reverse osmosis membrane, impurities, ions, microparticles, and dissolved solids in the alkaline solution are removed, improving the quality of the recycled alkaline solution, ensuring the cleanliness of the recycled alkaline solution, reducing the damage to fabrics caused by fiber impurities and pollutants, and lowering production costs and energy consumption.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an alkaline solution recycling mercerizing machine, including an alkali soaking tank, an alkali soaking trough at one end of the alkali soaking tank, an alkali removal trough at one end of the alkali soaking tank, a partition block fixed between the alkali soaking trough and the alkali removal trough, a treatment tank fixed on the outer wall of the alkali soaking tank, a cleaning component inside the treatment tank, and two alkali discharge pipes fixed on the treatment tank, one end of each of the two alkali discharge pipes being connected to the alkali soaking trough, and the other ends of each of the two alkali discharge pipes being located at the upper end of the treatment tank;

[0007] The lower end of the treatment tank is connected to a suction pipe, and multiple first filters are connected to the suction pipe. Each first filter is equipped with an alkali-resistant nanofiltration membrane. The concentrate end of the first filter is connected to a permeate pipe, and a second filter is connected to the permeate pipe. Each second filter is equipped with a reverse osmosis membrane, and the product water end of the second filter is connected to a pure water pipe.

[0008] Preferably, the cleaning assembly includes a filter screen, which is inserted into the treatment tank. The filter screen is inclined, and a guide block is installed on the top surface of the filter screen. A collection block is provided at the lower end of one side of the guide block. The bottom surface of the inner wall of the collection block is inclined, and a discharge port is opened on the outer wall of one end of the collection block. A perforated conveyor belt is installed on one side of the filter screen. Multiple paddles are fixedly arranged in a uniform structure on the outer wall of the perforated conveyor belt. The outer wall of the paddles is slidably connected to the outer wall of the filter screen.

[0009] The above technical solution uses a filter screen to intercept impurities and fibers in the alkaline solution.

[0010] Preferably, the inner wall of the perforated conveyor belt has two rotating shafts in a symmetrical structure. The outer peripheral walls of the two rotating shafts are respectively rotatably connected to the processing pool. Two blocks are fixed on the top surface of the processing pool. A servo motor is mounted on the outer wall of one of the blocks through a mounting base. The output shaft of the servo motor is coaxially connected to one of the rotating shafts.

[0011] The above technical solution uses a servo motor to drive one of the rotating shafts to rotate, causing the paddles on the perforated conveyor belt to slide against the outer wall of the filter screen, thus scraping away impurities on the filter screen.

[0012] Preferably, a first water pump is installed at the lower end of the treatment tank via a mounting base. The inlet of the first water pump is connected to the inside of the treatment tank, and the outlet of the first water pump is connected to a suction pipe.

[0013] The above technical solution involves using a first water pump to draw water into a suction pipe and then transporting it into multiple first filters.

[0014] Preferably, it also includes a waste liquid pipe, which is connected to the water production end of a plurality of first filters.

[0015] Preferably, the alkali soaking tank is connected to an L-shaped reflux pipe, one end of which is connected to an alkali output pipe, and the other end of which is connected to the concentrate end of a plurality of second filters.

[0016] Through the above technical solution, the concentrated water generated at the concentrated water end of the second filter is transported back to the alkali soaking tank through the alkali output pipe and the L-shaped return pipe, realizing the reuse of alkali, improving the recycling effect of alkali in the mercerizing process, and reducing the waste of alkali.

[0017] Preferably, a pure water tank is fixedly installed on the outer wall of the alkali leaching tank, and an inlet pipe is connected to the pure water tank. The other end of the inlet pipe is connected to multiple pure water pipes. A second water pump is installed at the upper end of the pure water tank. The second water pump is installed on the outer wall of the alkali leaching tank through a mounting base. The inlet end of the second water pump is connected to the lower end of the pure water tank, and the outlet end of the second water pump is connected to a distribution pipe.

[0018] Preferably, the distribution pipe is installed at the upper edge of the alkali leaching tank, and multiple alkali removal spray pipes are connected to the distribution pipe. The bottom surface of the alkali removal spray pipes is uniformly arranged and connected to multiple spray heads.

[0019] Through the above technical solution, the spray head at the bottom of the alkali removal spray pipe sprays pure water evenly onto the fabric to remove the residual alkali solution on the fabric.

[0020] The beneficial effects of this utility model are:

[0021] 1. Fabrics requiring mercerizing are placed in an alkali-soaking tank, where they come into contact with the alkali solution for mercerizing. The treated fabrics then enter an alkali removal tank for alkali removal and neutralization. During alkali soaking, the alkali solution is transported to the treatment tank via a drain pipe and undergoes initial cleaning by a cleaning assembly. The cleaned alkali solution is then transported through a suction pipe to multiple first filters, where it is filtered by an alkali-resistant nanofiltration membrane. This membrane traps impurities and ions in the alkali solution, producing concentrated alkali solution and permeate. The concentrated alkali solution and permeate then enter a second filter via a water permeate pipe, where they are further filtered by a reverse osmosis membrane. This removes tiny particles and dissolved solids from the permeate, producing pure water which is discharged to the outside via a pure water pipe. This dual filtration process using the alkali-resistant nanofiltration and reverse osmosis membranes removes impurities, ions, tiny particles, and dissolved solids from the alkali solution, improving the quality of the recycled alkali solution, ensuring its cleanliness, reducing damage to the fabric from fiber impurities and contaminants, and lowering production costs and energy consumption.

[0022] 2. When the alkali solution is pumped into the suction pipe by the first water pump and delivered to the inside of multiple first filters, the alkali solution inside the treatment tank flows and is intercepted by the filter screen to remove impurities and fibers. At the same time, a servo motor drives one of the rotating shafts to rotate, which in turn drives the perforated conveyor belt. During the rotation, the paddles on the perforated conveyor belt slide against the outer wall of the filter screen, scraping the impurities on the filter screen. This causes the impurities and fibers accumulated on the paddles to slide off the top surface of the guide block and into the collection block. Under the action of gravity, the impurities are discharged from the outlet to the outside, reducing the accumulation and clogging of impurities, improving cleaning efficiency, and facilitating the continuous interception of impurities in the alkali solution by the filter screen.

[0023] 3. The concentrated water after filtration by the first filter is discharged to the outside through the waste liquid pipe for collection and treatment. The concentrated water generated at the concentrated water end of the second filter is transported back to the alkali soaking tank through the alkali output pipe and the L-shaped return pipe, realizing the reuse of alkali, improving the recycling effect of alkali in the mercerizing process, and reducing the waste of alkali.

[0024] 4. The purified water produced after filtration by the second filter is transported to the pure water tank for storage through the inlet pipe. The purified water in the pure water tank is then transported to multiple alkali removal spray pipes through the distribution pipe by the second water pump. The spray head at the bottom of the alkali removal spray pipe sprays the purified water evenly onto the fabric, removing the residual alkali on the fabric, improving the alkali removal effect, and saving water resources.

One end of the two alkali discharge pipes 7 is connected to the alkali soaking tank 2, and the other end of the two alkali discharge pipes 7 is located at the upper end of the treatment tank 5.

[0035] The lower end of the treatment tank 5 is connected to a suction pipe 8, and multiple first filters 9 are connected to the suction pipe 8. An alkali-resistant nanofiltration membrane 10 is installed inside the first filter 9. The concentrate end of the first filter 9 is connected to a permeate pipe 11, and a second filter 12 is connected to the permeate pipe 11. A reverse osmosis membrane 13 is installed inside the second filter 12, and a pure water pipe 14 is connected to the product water end of the second filter 12.

[0036] The cleaning component 6 includes a filter screen 601, which is inserted into the treatment tank 5. The filter screen 601 is inclined, and a guide block 602 is installed on the top surface of the filter screen 601. A collection block 608 is provided at the lower end of one side of the guide block 602. The bottom surface of the inner wall of the collection block 608 is inclined, and a discharge port 609 is opened on the outer wall of one end of the collection block 608. A perforated conveyor belt 603 is installed on one side of the filter screen 601. Multiple levers 604 are fixed on the outer wall of the perforated conveyor belt 603 in a uniformly arranged structure. The outer wall of the levers 604 is slidably connected to the outer wall of the filter screen 601. The filter screen 601 intercepts impurities and fibers in the alkaline solution.

[0037] The inner wall of the perforated conveyor belt 603 has a symmetrical structure with two rotating shafts 605. The outer peripheral walls of the two rotating shafts 605 are rotatably connected to the treatment tank 5. Two blocks 606 are fixed on the top surface of the treatment tank 5. A servo motor 607 is mounted on the outer wall of one of the blocks 606 through a mounting base. The output shaft of the servo motor 607 is coaxially connected to one of the rotating shafts 605. The servo motor 607 drives one of the rotating shafts 605 to rotate, causing the paddle 604 on the perforated conveyor belt 603 to slide against the outer wall of the filter screen 601, scraping the impurities on the filter screen 601.

[0038] A first water pump 15 is installed at the lower end of the treatment tank 5 via a mounting base. The inlet end of the first water pump 15 is connected to the inside of the treatment tank 5, and the outlet end of the first water pump 15 is connected to the suction pipe 8. The water is pumped by the first water pump 15 to the suction pipe 8 and then transported to the inside of multiple first filters 9.

[0039] Working principle: First, the fabric that needs mercerizing is put into the alkali soaking tank 1 and comes into contact with the alkali soaking tank 2 containing alkali solution for mercerizing. The treated fabric then enters the alkali removal tank 3 for alkali removal and neutralization. During alkali soaking, the alkali solution is transported to the treatment tank 5 through the alkali discharge pipe 7 and preliminarily cleaned by the cleaning component 6. The cleaned alkali solution is then transported to multiple first filters 9 through the suction pipe 8 and filtered through the alkali-resistant nanofiltration membrane 10. The alkali-resistant nanofiltration membrane 10 intercepts impurities and ions in the alkali solution, producing concentrated alkali solution and permeate.

[0040] The concentrated alkali solution and permeate enter the second filter 12 through the permeate pipe 11, and are further filtered by the reverse osmosis membrane 13 to remove tiny particles and dissolved solids in the permeate. The resulting pure water is discharged to the outside through the pure water pipe 14. Through the dual filtration of the alkali-resistant nanofiltration membrane 10 and the reverse osmosis membrane 13, impurities, ions, tiny particles and dissolved solids in the alkali solution are removed, improving the quality of the recycled alkali solution, ensuring the cleanliness of the recycled alkali solution, reducing the damage of fiber impurities and pollutants to the fabric, and reducing production costs and energy consumption.

[0041] When the alkali solution is pumped into the suction pipe 8 by the first water pump 15 and delivered to the inside of multiple first filters 9, the alkali solution inside the treatment tank 5 flows and is intercepted by the filter screen 601. At the same time, the servo motor 607 drives one of the rotating shafts 605 to rotate, driving the perforated conveyor belt 603 to operate. During the rotation, the paddle 604 on the perforated conveyor belt 603 slides against the outer wall of the filter screen 601, scraping the impurities on the filter screen 601. The impurities and fibers accumulated on the paddle 604 slide down to the top surface of the guide block 602 and into the collection block 608. Under the action of gravity, the impurities are discharged to the outside from the discharge port 609, reducing the accumulation and clogging of impurities, improving cleaning efficiency, and facilitating the continuous interception of impurities in the alkali solution by the filter screen 601.

One end of the L-shaped return pipe 17 is connected to an alkali output pipe 18, and the other end of the alkali output pipe 18 is connected to the concentrated water end of multiple second filters 12. The concentrated water generated by the concentrated water end of the second filters 12 is transported back to the alkali soaking tank 1 through the alkali output pipe 18 and the L-shaped return pipe 17, realizing the reuse of alkali, improving the recycling effect of alkali in the mercerizing process, and reducing the waste of alkali.

[0043] A pure water tank 19 is fixedly installed on the outer wall of the alkali soaking tank 1. An inlet pipe 20 is connected to the pure water tank 19. The other end of the inlet pipe 20 is connected to multiple pure water pipes 14. A second water pump 21 is installed at the upper end of the pure water tank 19. The second water pump 21 is installed on the outer wall of the alkali soaking tank 1 through a mounting base.

The distribution pipe 22 is installed at the upper edge of the alkali soaking tank 1. Multiple alkali removal spray pipes 23 are connected to the distribution pipe 22. Multiple spray heads 24 are connected to the bottom surface of the alkali removal spray pipes 23 in a uniform arrangement. The spray heads 24 on the bottom surface of the alkali removal spray pipes 23 spray pure water evenly onto the fabric to remove the residual alkali solution on the fabric.

[0044] During use, the concentrated water (wastewater containing impurities and incompletely retained alkali solution) after being filtered by the first filter 9 is discharged to the outside for collection and treatment through the waste liquid pipe 16. The concentrated water generated at the concentrated water end of the second filter 12 (i.e., the wastewater containing a high concentration of alkali solution remaining after being filtered by the reverse osmosis membrane 13) is transported back to the alkali soaking tank 1 through the alkali solution output pipe 18 and the L-shaped return pipe 17, realizing the reuse of alkali solution, improving the recycling effect of alkali solution in the mercerizing process, and reducing the waste of alkali solution.

[0045] The purified water produced after filtration by the second filter 12 is transported to the pure water tank 19 for storage through the inlet pipe 20. The purified water in the pure water tank 19 is then transported to multiple alkali removal spray pipes 23 through the distribution pipe 22 by the second water pump 21.
