Description

Technical Field

[0001] The invention relates to the field of viscose filtration, in particular to a high-efficiency filtration and recovery device for impurities in viscose production. Background Art

[0002] Cellulose sulfonate forms viscose after dissolving. The viscose needs to be left for a period of time to form qualified viscose that meets the spinning process. This process is called maturation. The viscose will inevitably solidify into gel particles during storage, affecting the quality of the viscose and reducing its spinnability. Therefore, a tank filter is set behind each barrel to filter out the gel particles and reduce the filtering pressure on the subsequent KKF filter.

[0003] The patent application publication number is CN218553221U, which discloses a viscose filtering and recovery device. After the plasticized water enters the filter chamber, as the water level rises to the filter layer formed by the fiber filaments, the plastic particles are intercepted by the fiber filaments in the filter layer. After being filtered, the plasticized water enters the recovery chamber from the overflow port for recycling. The device has a simple structure, a large filtering capacity, a strong dirt interception ability, and the fiber filaments are inexpensive, which reduces the cost of using the equipment.

[0004] In the prior art, during the filtration stage of viscose, the filtration system is relatively simple and the filtration quality is poor. It is only for overall filtration without filtering at various positions and different parts, resulting in the filtration failing to achieve the desired effect and also causing a waste of some raw materials.

The filtering capacity can be enhanced through different types of filtering mechanisms at various positions to form a new type of high-efficiency filtering system, which improves the filtering quality without changing the filtering time.

[0021] When filter barrel 1 3 rotates, the limiting ring 38 can drive filter barrel 2 5 to rotate accordingly, so that filter barrel 1 3 and filter barrel 2 5 can move synchronously during the filtering process, avoiding the need to install another motor 34 when starting the rotation of filter barrel 2 5, and accordingly saving the installation of motor 34, so that filter barrel 2 5 can move with the movement of filter barrel 1 3, so that filter barrel 1 3 and filter barrel 2 5 can move synchronously when working, avoiding the energy consumption of additional power source, and significantly reducing the overall energy consumption.

[0022] Embodiment 2, on the basis of embodiment 1, a cavity is opened inside the mounting frame 32, a round brush 37 is fixedly connected to the outer wall of the mounting frame 32, a nozzle 36 is fixedly connected to the outer wall of the mounting frame 32, the outer wall of the nozzle 36 is in movable contact with the inside of the round brush 37, and a water pipe 35 is fixedly connected to the outer wall of one side of the mounting frame 32.

[0023] While replacing the filter barrel 1 3, the filter barrel 2 5 is cleaned more intensively, which avoids the need to arrange separate time for cleaning the filter barrel 2 5, saves overall maintenance time, and improves work efficiency. Accordingly, water is sprayed through the water nozzle 36 to increase the cleaning effect, ensure the cleanliness of the surface of the filter barrel 2 5, maintain good filtering performance, and ensure the filtering quality of the entire system. By strengthening cleaning rather than frequent replacement, resources are used rationally and waste is reduced.

[0024] Embodiment three, on the basis of embodiment two, the outer wall on one side of baffle four 310 is fixedly connected to the shell 4, cleaning brushes 41 are fixedly connected to both sides of the outer wall at the bottom of the shell 4, cleaning brushes 42 are fixedly connected to the interior above the shell 4, a strip groove 46 is opened in the lower middle position of the interior of the shell 4, the interior of the shell 4 is connected with the outer wall of the water pipe 35, a slag discharge pipe 44 is rotatably connected to the middle position of the interior of the filter barrel 3, a slide groove 43 is opened on the outer wall at the top of the slag discharge pipe 44, and a baffle two 45 is slidably connected to the interior of the slide groove 43.

[0025] By setting the cleaning brush 1 41 and the cleaning brush 2 42, it is prevented that impurities still adhere to the inner wall of the filter barrel 1 3 and the filter barrel 2 5 after the filter barrel 1 3 and the filter barrel 2 5 rotate one circle. Accordingly, the filter barrel 1 3 and the filter barrel 2 5 can be cleaned while rotating, so that the filtering effect of the filter barrel 1 3 and the filter barrel 2 5 is always maintained in the best state, which improves the overall filtering effect, prevents the filter barrel 1 3 and the filter barrel 2 5 from being blocked due to the accumulation of impurities, and ensures the continuity of the production process by removing impurities in time.

[0026] Embodiment 4, on the basis of embodiment 3, the interior of the mounting shell 2 is fixedly connected with a sealing gasket 22, the interior of the sealing gasket 22 is movably connected with a plate and frame filter frame 27, the outer wall on the top of the mounting shell 2 is fixedly connected with a temporary storage shell 23, the middle position inside the plate and frame filter frame 27 is movably contacted with an isolation plate 271, the outer walls on both sides of the isolation plate 271 are fixedly connected with filter cloth 272, the outer wall on one side of the filter cloth 272 is movably contacted with a circular ring, the outer wall of the circular ring is fixedly connected to the inner wall of the plate and frame filter frame 27, and the outer wall on the other side of the filter cloth 272 is movably contacted with a metal mesh 273.

[0027] By installing a plate and frame filter frame 27 inside the shell 2, when the viscose passes through the plate and frame filter frame 27, small particles in the viscose can be filtered through the isolation plate 271 and the filter cloth 272, thereby improving the quality of the viscose. By adding a metal mesh 273 to the plate and frame filter frame 27, the damage to the single filter cloth 272 can be reduced while the filtering effect is improved.

[0028] Embodiment 5, on the basis of embodiment 4, the interior of the temporary storage shell 23 is movably connected with the outer wall of the plate and frame filter frame 27, the interior of the mounting shell 2 is slidably connected with a pull rod 28, the outer wall at the top of the pull rod 28 is slidably connected with the interior of the temporary storage shell 23, the outer wall at the top of the pull rod 28 is rotatably connected with a limit block 29, the outer wall at the bottom of the limit block 29 is movably contacted with the outer wall at the top of the plate and frame filter frame 27, the interior of the temporary storage shell 23 is movably connected with a baffle 1 24, the outer wall at the top of the baffle 1 24 is provided with a slide groove 3 25, the interior of the temporary storage shell 23 is located inside the slide groove 3 25 and is fixedly connected with a stopper 26, and the outer wall of the stopper 26 is slidably connected with the interior of the slide groove 3 25.

[0029] By pushing the pull rod 28 to its original position, the plate and frame filter frame 27 can be replaced, avoiding the complicated replacement structure that takes a long time to replace the plate and frame filter frame 27. Accordingly, the plate and frame filter frame 27 is replaced by pulling the pull rod 28, thereby saving the replacement time of the plate and frame filter frame 27. At the same time, the two plate and frame filter frames 27 are tightly fitted during the replacement process, which will not affect the filtering of the viscose by the plate and frame filter frame 27 during replacement, thereby reducing the downtime of the device.

[0030] Embodiment 6, on the basis of embodiment 5, a circular groove is opened inside the plate and frame filter frame 27, and a baffle plate 3 63 is movably contacted inside the circular groove. The outer walls on the opposite sides of the two baffle plates 3 63 are fixedly connected by a push rod 61, and the outer wall of the push rod 61 is slidably connected to the inside of the plate and frame filter frame 27. A reset spring 62 is movably inserted into the outer wall of the push rod 61, and the outer wall of the plate and frame filter frame 27 is movably contacted with the limit frame 6, and the outer wall at the bottom of the limit frame 6 is movably contacted with the outer wall at the top of the push rod 61.

[0031] When the plate and frame filter frame 27 is moved out from the interior of the mounting shell 2, the limit frame 6 can be pushed to one side of the plate and frame filter frame 27 so that the limit frame 6 leaves the top of the push rod 61. Then, under the action of the return spring 62, the baffle plate three 63 can be driven to move toward the interior of the plate and frame filter frame 27, thereby releasing the interception of the metal mesh 273 by the baffle plate three 63, and the metal mesh 273 and the isolation plate 271 can be taken out from the interior of the plate and frame filter frame 27 for easy replacement or maintenance.

[0032] In actual use, when working, first, the glue enters the interior of the filter barrel 3 through the feed pipe 33, and the motor 34 is started. Then, through the rotation of the motor 34, the bracket 31 can drive the filter barrel 3 to rotate accordingly, and the glue entering the interior of the filter barrel 3 is initially filtered, and the solidified glue particles are intercepted. Since the filter barrel 3 rotates during operation, the contact position between the glue and the filter barrel 3 can be continuously changed, thereby avoiding local blockage of the filter barrel 3. Accordingly, the rotation of the filter barrel 3 improves the filtering effect of the glue, so that the filter barrel 3 intercepts the solidified glue particles that stick to the filter barrel 3 and rotates with the filter barrel 3, so that the position where the filter barrel 3 contacts the glue always maintains efficient filtration.

[0033] It should be noted that the opening at one end of the filter barrel 3 is not a complete opening but a half opening, and one end of the feed pipe 33 extends into a part of the interior of the filter barrel 3. In the case of a half opening, the baffle on one side of the filter barrel 3 intercepts the internal glue to prevent the glue from flowing out of the opening of the filter barrel 3. Secondly, the glue inside the filter barrel 3 will not exceed the half-open position.

[0034] The viscose filtered by the filter barrel 1 3 can directly enter the interior of the filter barrel 2 5, and the filter barrel 2 5 performs secondary filtration on the viscose, thereby increasing the cleanliness of the viscose. The filter holes of the filter barrel 2 5 are smaller than the filter mesh holes of the filter barrel 1 3, thereby avoiding the contamination of the viscose with some impurities that cannot be completely removed by filtering by the filter barrel 3 alone. Accordingly, through a multi-pass filtration method, the removal of impurities in the viscose is improved to ensure the cleanliness of the viscose.

[0035] After the limiting ring 38 is driven by the filter barrel 1 3 to be inserted into the interior of the groove 39, the connection between the limiting ring 38 and the groove 39 fixes the filter barrel 2 5 and the filter barrel 1 3. At this time, under the rotation of the filter barrel 1 3, the limiting ring 38 can drive the filter barrel 2 5 to rotate accordingly, so that the filter barrel 1 3 and the filter barrel 2 5 can move synchronously during the filtration process, avoiding the need to install another motor 34 when starting the rotation of the filter barrel 2 5, and correspondingly saving the installation of the motor 34, so that the filter barrel 2 5 moves with the movement of the filter barrel 1 3, so that the filter barrel 1 3 and the filter barrel 2 5 can move synchronously. It can perform synchronous movement during operation, which prevents the energy consumption of additional power sources and significantly reduces the overall energy consumption. At the same time, since there is active contact between filter barrel 1 3 and filter barrel 2 5, they can be separately disassembled, which is convenient for the operator to perform separate cleaning and maintenance processes for each component, avoiding the need to replace the entire filter barrel when one of the filter barrels is damaged, thereby reducing the replacement cost accordingly. Since there is a non-rigid connection between filter barrel 1 3 and filter barrel 2 5, the wear caused by direct hard contact is effectively reduced during operation, the service life of each component is extended, and the equipment maintenance cost and frequency are reduced.

[0036] By using the shell 4 provided between the filter barrel 1 3 and the filter barrel 2 5, when the filter barrel 1 3 and the filter barrel 2 5 drive the impurities adhering to the inner wall to rotate the position of the shell 4, the filter barrel 1 3 and the filter barrel 2 5 can be cleaned by using the cleaning brush 2 42 and the cleaning brush 1 41 provided on the shell 4. By inserting the cleaning brush 1 41 into the filter mesh of the filter barrel 1 3, the impurities on the inner wall of the filter barrel 1 3 can be cleaned, and the cleaned impurities enter the inside of the slag discharge pipe 44 through the baffle 2 45, and then when the cleaning brush 2 42 scrapes the inner wall of the filter barrel 2 5, the impurities are driven by the filter barrel 2 5 to rotate to the highest point of the filter barrel 2 5, and the impurities fall into the inside of the shell 4 under the scraping of the cleaning brush 2 42, and then pass through the strip groove 46 provided at the bottom of the shell 4, so that the impurities are discharged through the strip groove 46 The impurities are collected and processed by the setting of the tank body 12, so that the impurities can be reused for a second time, which not only reduces the waste of resources but also reduces the production cost. The setting of the cleaning brush 1 41 and the cleaning brush 2 42 can prevent the impurities from adhering to the inner walls of the filter barrel 1 3 and the filter barrel 2 5 after the filter barrel 1 3 and the filter barrel 2 5 rotate one circle. Accordingly, the filter barrel 1 3 and the filter barrel 2 5 can be cleaned while rotating, so that the filtering effect of the filter barrel 1 3 and the filter barrel 2 5 is always maintained in the best state, thereby improving the overall filtering effect, preventing the filter barrel 1 3 and the filter barrel 2 5 from being blocked due to the accumulation of impurities, and ensuring the continuity of the production process by removing impurities in time.

[0037] The movable covers at both ends of the tank body 1 are movably connected to the tank body 1. When the movable covers at both ends of the tank body 1 are removed, the filter barrel 1 3 and the filter barrel 2 5 inside the tank body 1 can be removed from the inside of the tank body 1, so as to facilitate the replacement or maintenance of the filter barrel 3 and the filter barrel 2 5. After the filter barrel 3 is removed from the inside of the tank body 1, the water pipe 35 is now connected to the water source. At this time, after the movable cover with the motor 34 is removed from the tank body 1, due to the connection between the motor 34 and the bracket 31, the motor 34 can drive the bracket 31 to slide out of the inside of the tank body 1. Since the movement of the bracket 31 can drive the filter barrel 3 to move accordingly, during the separation process of the filter barrel 3 from the inside of the tank body 1, the mounting frame 32 can drive the round brush 37 to clean the filter barrel 2 5 The filter barrel 25 is cleaned, and then water enters the interior of the mounting frame 32 through the water pipe 35, and is finally sprayed onto the filter barrel 25 from the nozzle 36, thereby increasing the cleaning effect of the filter barrel 25. Since the filter barrel 25 is a secondary filter of the viscose, the impurities intercepted are relatively less than those of the filter barrel 1 3, so the replacement frequency of the filter barrel 25 is less than that of the filter barrel 1 3. While replacing the filter barrel 1 3, the filter barrel 25 is cleaned more effectively, thereby preventing the need to arrange a separate time to clean the filter barrel 25, saving overall maintenance time, and improving work efficiency. Accordingly, water is sprayed through the water nozzle 36 to increase the cleaning effect, thereby ensuring the cleanliness of the surface of the filter barrel 25, maintaining good filtering performance, and ensuring the filtering quality of the entire system. By strengthening cleaning rather than frequent replacement, resources are used rationally and unnecessary waste is reduced.

[0038] Then, the spare filter barrel 3 and the movable cover are inserted into the interior of the tank body 1, and the replaced filter barrel 3 can be cleaned or repaired. By replacing the two filter barrels 3, the downtime of the device can be reduced.

[0039] It should be noted that when the filter barrel 3 is replaced again, it means that the entire device is in a non-working state. At this time, there is no glue inside the tank body 1, the tank body 2 11 and the tank body 3 12. At this time, the two filtering structures inside the mounting shell 2 are taken out to create a gap inside the mounting shell 2, so that the water inside the tank body 1 passes through the inside of the connecting pipe 13 and is finally discharged from the mounting shell 2. A valve is provided on the outer wall of the connecting pipe 13 close to the side of the tank body 2 11.

[0040] It should be noted that: after the filter barrel 3 is taken out from the interior of the tank body 1, through the sliding connection between the baffle 2 45 and the slide groove 1 43, when the inner wall of the filter barrel 3 contacts the baffle 2 45, the baffle 2 45 can be driven to move accordingly, preventing the baffle 2 45 from causing obstruction when the filter barrel 3 is disassembled.

[0041] The viscose that has been processed through the filter barrel 2 5 enters the interior of the tank body 2 11 through the connecting pipe 1 13. When the viscose passes through the connecting pipe 1 13, it will be filtered again through the interior of the mounting shell 2. At the same time, the waste material processed inside the tank body 3 12 needs to be filtered through the mounting shell 2 when it is discharged through the connecting pipe 2 14 for secondary use. This avoids the situation where the viscose filtering system is relatively single and there is no filtering for each position and different parts. Accordingly, the viscose is filtered before entering the next process, thereby improving the filtering quality while keeping the filtering time unchanged.

[0042] By installing a plate and frame filter frame 27 inside the shell 2, when the viscose passes through the plate and frame filter frame 27, small particles in the viscose can be filtered through the isolation plate 271 and the filter cloth 272, thereby improving the quality of the viscose. By adding a metal mesh 273 to the plate and frame filter frame 27, the damage to the single filter cloth 272 can be reduced while the filtering effect is improved.

[0043] The operator pulls the baffle plate 24 at the bottom of the installation shell 2 out to one side of the installation shell 2, and then the operator pulls the pull rod 28. When the pull rod 28 moves downward, the limit block 29 can drive the plate-frame filter frame 27 inside the temporary storage shell 23 to move downward, so that the plate-frame filter frame 27 inside the temporary storage shell 23 pushes the plate-frame filter frame 27 inside the installation shell 2 downward. When the plate-frame filter frame 27 inside the installation shell 2 is completely moved out of the interior of the installation shell 2, the plate-frame filter frame 27 inside the temporary storage shell 23 can be moved to the By going to the inside of the mounting shell 2 and pushing the pull rod 28 to its original position, the plate and frame filter frame 27 can be replaced, avoiding the complicated replacement structure that takes a long time to replace the plate and frame filter frame 27. Accordingly, the plate and frame filter frame 27 is replaced by pulling the pull rod 28, thereby saving the replacement time of the plate and frame filter frame 27. At the same time, the two plate and frame filter frames 27 are closely fitted during the replacement process, which will not affect the filtering of the adhesive by the plate and frame filter frame 27 during replacement, thereby reducing the downtime of the device.

[0044] By moving the pull rod 28 to one side of the limit frame 6 , the limit frame 6 can be limited when it is working, so as to prevent the limit frame 6 from moving during work, thereby increasing the stability of the limit frame 6 accordingly.

[0045] It should be noted that: by pulling out the baffle 24 on the temporary storage shell 23 to one side of the temporary storage shell 23, and then rotating the limit block 29 90 degrees to be flush with the pull rod 28, the spare plate and frame filter rack 27 can be inserted into the interior of the temporary storage shell 23, and then the limit block 29 is restored to its original position, so as to facilitate the placement of the spare plate and frame filter rack 27.

[0046] When the plate and frame filter frame 27 is moved out from the interior of the mounting shell 2, the limit frame 6 can be pushed to one side of the plate and frame filter frame 27 so that the limit frame 6 leaves the top of the push rod 61. Then, under the action of the return spring 62, the baffle plate three 63 can be driven to move toward the interior of the plate and frame filter frame 27, thereby releasing the interception of the metal mesh 273 by the baffle plate three 63, and the metal mesh 273 and the isolation plate 271 can be taken out from the interior of the plate and frame filter frame 27 for easy replacement or maintenance.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
