Description

Technical Field

[0001] The present invention belongs to the technical field of viscose staple fiber treatment, and particularly relates to a viscose staple fiber cooking device. Background Art

[0002] The post-treatment of viscose staple fiber is an important process in the production process of viscose fiber. The post-treatment mainly consists of a fiber feeding tank and a refining machine. The fiber feeding tank device mainly removes residual carbon disulfide (CS2), removes elemental sulfur on the fiber surface, removes the residual acid bath on the fiber, and flushes and evenly distributes the fiber through high-temperature washing and steam cooking of the fiber, effectively improving the looseness of the fiber, reducing yellow fibers, narrowing the color difference of the finished product, and facilitating subsequent processes such as water washing.

[0003] In the prior art, the fiber feeding tank is made of stainless steel and is provided with steam spray pipes at the bottom. The fiber is sent into the fiber feeding tank by acidic water, and the steam spray pipes at the bottom of the tank spray steam into the tank to keep the temperature in the tank at about 98°C, while loosening and flushing the fiber. However, during the flushing process of the staple fiber, it is easy to break and accumulate in the tank, affecting the subsequent incomplete flushing of the fiber and uneven laying of the cotton. After entering the refining process, it affects the water washing, desulfurization, bleaching, and oiling of the refining, resulting in uneven moisture regain and quality fluctuations of the finished product.

[0004] Therefore, the present invention proposes a viscose staple fiber cooking device to solve the problem in the prior art that relying on steam spray pipes to disperse the fiber easily causes the fiber to break and accumulate in the tank during the dispersion process, affecting the subsequent incomplete dispersion of the fiber and uneven laying of the cotton. By improving the design of the interior of the cooking tank and integrating the carding net structure and the diversion structure, the fiber is dispersed into the diversion structure and is orderly dispersed by the carding frame net structure, and at the same time, the broken fiber is intercepted to avoid blockage and accumulation, affecting the subsequent steam dispersion.

Detailed implementation manners

[0019] In order to clearly and completely describe the purpose, technical solution of the present invention and make the advantages more clear, the following further details the embodiments of the present invention with reference to the drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present invention.

[0020] Embodiment 1 Please refer to Figures 1 to 14, the present invention provides a technical solution: a viscose staple fiber cooking device, including a fiber feeding trough frame 1. Above the fiber feeding trough frame 1, there are a dispersion trough 3 and a cooking trough 4. The connection between the dispersion trough 3 and the cooking trough 4 is through. In this embodiment, the dispersion trough 3 and the cooking trough 4 are welded together. The fiber feeding trough frame 1 mainly serves to support the dispersion trough 3 and the cooking trough 4, making the height of the dispersion trough 3 higher than that of the cooking trough 4. At the bottom of the cooking trough 4, there is a sewage discharge and maintenance pipe. All the pipelines and rotating shaft components installed inside the dispersion trough 3 and the cooking trough 4 and the side walls of the dispersion trough 3 and the cooking trough 4 should use a sealing structure to maintain airtightness, which is a conventional setting and will not be elaborated in this embodiment. Inside the dispersion trough 3, there are a dispersion guide plate 33 and a distribution component 34. The dispersion guide plate 33 mainly serves as a guide, and the distribution component 34 mainly serves to disperse the passing fibers so that they can spread out and enter the cooking trough 4 for cooking. Inside the cooking trough 4, there is a fixing frame 43. On both sides of the cooking trough 4, there are steam input main pipes 42 fixedly installed respectively. On the upper surface of the bottom of the cooking trough 4, there are steam spray pipes 421 evenly fixedly installed. One end of each steam spray pipe 421 is fixedly connected to the bottom of the steam input main pipe 42 through a flange pipe. The steam input main pipes 42 on both sides of the cooking trough 4 are connected through connecting steam input pipes, and then the steam is distributed and conveyed to the steam spray pipes 421 laid at the bottom of the cooking trough 4 respectively. The number of steam spray pipes 421 can be customized according to production needs. In order to ensure the uniformity of cooking, the inlet steam branch pipes connecting the steam spray pipes 421 and the steam input main pipes 42 on both sides should be designed to be alternately arranged. Above the steam spray pipes 421, there are steam nozzles 422 evenly distributed. Similarly, the length of the steam spray pipes 421 and the distribution quantity of the steam nozzles 422 can also be customized according to production needs. The injection pipe angles of the steam nozzles 422 are distributed in a 60°90°60° staggered manner. On the upper surface of the cooking trough 4, there is a steam rising area cover 41 fixedly installed by bolts. On the top of the steam rising area cover 41, there is a carbon disulfide recovery pipe 411. The fixing frame 43 is arranged above the steam input main pipe 42, and the two side surfaces of the fixing frame 43 are fixedly connected to the inner wall surface of the cooking trough 4 respectively; the fixing frame 43 mainly covers above the steam spray pipes 421 and mainly serves to install the long guide fins 433. The long guide fins 433 are evenly spaced. The distribution rule of the long guide fins 433 should be staggered according to the distribution of the steam nozzles 422, so that the steam sprayed by the steam nozzles 422 can pass through the steam troughs 434 formed between the long guide fins 433, fully steam loosen the fibers, fully cook and remove the residual CS2, and cover the space above the cooking trough 4 through the steam rising area cover 41. The rising steam carrying carbon disulfide can be connected to the condensation recovery and separation workshop through the carbon disulfide recovery pipe 411 to effectively recover carbon disulfide, reduce environmental pollution and improve resource utilization rate.

[0021] Embodiment 2 Please refer to Figures 1 to 14, on the basis of the first embodiment, this embodiment further proposes that the dispersion guide plate 33 is inclined and fixedly installed on the inner side wall of the dispersion tank 3. A scouring and flow-blocking strip 331 is fixedly installed above the surface of the dispersion guide plate 33. The scouring and flow-blocking strip 331 has a structure with lower heights on both sides and a rounded convexity in the middle. Combing fins 332 are evenly distributed below the surface of the dispersion guide plate 33. The upper surface of the dispersion tank 3 is fixedly installed with a dispersion tank cover 31 through bolts. An input pipe 311 is fixedly installed at the top of the dispersion tank cover 31. A hot water inlet pipe 32 is fixedly installed on the outer side wall of the dispersion tank 3. Spray branch pipes 321 are evenly distributed on the inner side wall of the hot water inlet pipe 32. The spray branch pipes 321 penetrate the side wall of the dispersion tank cover 31. The middle part of the hot water inlet pipe 32 is connected to the hot water inlet pipe through a connecting pipe. The hot water is conveyed into the dispersion tank 3 through the spray branch pipes 321. With the guiding action of the dispersion guide plate 33, the fibers entering the dispersion tank 3 through the input pipe 311 are continuously carried into the cooking tank 4 by the water flow. A dispersion spray flat nozzle 322 is fixedly installed at one end of the spray branch pipe 321. In particular, installing the dispersion spray flat nozzle 322 on the spray branch pipe 321 can make the water flow eject and generate a certain flow-blocking impact with the scouring and flow-blocking strip 331, so that the fibers are washed away and flow and disperse to both sides along the scouring and flow-blocking strip 331, and the fibers are initially dispersed.

[0022] Embodiment Three Please refer to Figures 1 to 14, on the basis of Embodiment 2, this embodiment further proposes that the distribution component 34 includes a motor 341, a conveying roller 342, a crank-rocker assembly 343, and a swing distributor 344. The motor 341 is fixedly installed on the outer surface of the dispersion tank 3. The conveying roller 342 is rotatably installed in the middle of the side wall of the dispersion tank 3. The swing distributor 344 is arranged between the dispersion guide plate 33 and the conveying roller 342. One end of the rotating shaft of the conveying roller 342 penetrates through the side wall of the dispersion tank 3 and is fixedly connected to the output shaft of the motor 341. The lower surface of the swing distributor 344 is evenly distributed with distribution fins 3441, and the distribution fins 3441 and the combing fins 332 are staggered. The outer surface of the conveying roller 342 is evenly distributed with dart-shaped fins 3421. The crank-rocker assembly 343 includes a crank and a connecting rod. The crank is rotatably installed on the side wall of the dispersion tank 3. The surface of the crank is movably connected to the surface of the output shaft of the motor 341 through a belt or chain assembly. One end of the connecting rod is movably connected to one end of the crank, and the other end of the connecting rod is movably connected to the side surface of the swing distributor 344. In this embodiment, the motor 341 plays a role in driving the conveying roller 342, and at the same time drives the swing distributor 344 to swing left and right through the crank-rocker assembly 343. The swing distributor 344 swings the distribution fins 3441 at its bottom to act on the combing fins 332, and cooperates with the combing fins 332 in an interlaced manner to evenly distribute the fibers under the action of water flow. The fibers are dispersed and conveyed above the transition guide plate 35 through the dart-shaped fins 3421 by the rotation of the conveying roller 342. A transition guide plate 35 is arranged on one side of the conveying roller 342. The middle of the lower surface of the transition guide plate 35 is hinged to the upper surface of the bottom of the cooking tank 4. The upper surface of the transition guide plate 35 is evenly distributed with guide short fins 351. A spring support rod 352 is movably installed between the lower surface of the transition guide plate 35 and the upper surface of the bottom of the cooking tank 4. The guide short fins 351 on the upper surface of the transition guide plate 35 are inner-folded triangular plates, which can play a role in guiding the water flow and fibers. When the dart-shaped fins 3421 rotate past, one end of the transition guide plate 35 will be pressed down, and then the transition guide plate 35 will reset under the cooperation of the spring support rod 352, so that the transition guide plate 35 cooperates with the rotation of the dart-shaped fins 3421 to produce regular left and right swings, so that the water flow carries the fibers to be dispersed and conveyed to the fixing frame 43, which is convenient for the fibers to be fully steamed by steam.

[0023] Embodiment 4 Please refer to Figures 1 to 14, on the basis of Embodiment III, the present embodiment further proposes that a slot 431 corresponding to the diversion short fin 351 is opened on one side of the fixing frame 43 close to the transition diversion plate 35. A triangular tail slot frame 432 is movably installed on the other side of the fixing frame 43. Between the slot 431 and the triangular tail slot frame 432, long diversion fins 433 are evenly distributed. The long diversion fins 433 are fixedly installed obliquely downward on the cross bars on both sides of the fixing frame 43. In this embodiment, the fixing frame 43 mainly serves to support and install the long diversion fins 433. The positions of the slot 431, the long diversion fins 433 and the diversion short fin 351 correspond one by one, and the long diversion fins 433 are also of a triangular inner folding plate structure, and are laid obliquely downward at equal intervals above the fixing frame 43 to continue to divert the water flow carrying the fibers. Steam slots 434 are provided between the long diversion fins 433. The function of the steam slots 434 formed by the intervals of the long diversion fins 433 is to allow the steam sprayed by the steam nozzles 422 to pass through, cook the passing fibers, remove the residual CS2, remove the elemental sulfur and acid bath solution on the fiber surface. The position of the long diversion fins 433 corresponds to the position of the slot 431. A combing frame net 435 is rotatably installed above one side of the fixing frame 43. The combing frame net 435 is composed of multiple groups of spaced slats adapted to the steam slots 434. The multiple groups of spaced slats are evenly distributed obliquely downward at equal intervals along the inclined direction of the long diversion fins 433. Multiple groups of thin cross bars are fixedly installed obliquely between two groups of spaced slats. The thin cross bars are arranged above the steam slots 434. A slot adapted to the thin cross bars is provided on the side wall of the triangular tail slot frame 432. The combing frame net 435 forms a combing net through the spaced slats and the thin cross bars, mainly serving to cooperate with the steam sprayed by the steam nozzles 422 and the water flow when the fibers pass through, and to disperse and evenly comb the fibers, effectively improving the looseness of the fibers, reducing the yellow residue of carbon disulfide, reducing the color difference of the finished product, and at the same time, it can also intercept the broken fibers to avoid the accumulation of fiber clusters causing blockage of the steam nozzles 422 and affecting the subsequent cooking effect. The triangular tail slot frame 432 is mainly snap-fitted and movably installed at the tail of the fixing frame 43 to intercept the broken fibers and other impurities combed out. When the combing frame net 435 is normally installed, under the action of gravity, one end of the combing frame net 435 will press and snap onto the upper part of the triangular tail slot frame 432. Activity slots adapted to the triangular tail slot frame 432 are provided on both sides of the fixing frame 43. When it is necessary to clean the cooking tank 4, open the sewage inspection pipe at the bottom of the cooking tank 4, drain the water, then open the steam rising area cover 41 above to lift one side of the combing frame net 435 to turn it over, and then take out the impurities intercepted inside the triangular tail slot frame 432. Then pull out the triangular tail slot frame 432 and reset the combing frame net 435. Finally, turn over the triangular tail slot frame 432 and move it along the activity slot of the fixing frame 43 to use the triangular tail slot frame 432 as a combing and cleaning scraping tooth to clean the combing frame net 435, realizing multiple uses of one object.

[0024] Embodiment V Please refer to Figures 1 to 14 Based on Embodiment 4, this embodiment further proposes that an output tank 5 is fixedly installed on one side of the cooking tank 4. In this embodiment, the output tank 5 mainly functions to install the conveying component 2 of the refiner, and conveys the fibers loosened by steaming to the refiner through the conveying component 2 of the refiner for subsequent processing. A shaking plate 51 is movably installed on the upper surface of the bottom of the side of the output tank 5 close to the cooking tank 4. A cam driving component 52 is arranged below the shaking plate 51. The cam driving component 52 is mainly composed of a small motor installed outside the output tank 5, a rotating shaft rotatably installed at the bottom of the output tank 5, and a cam fixedly installed on the rotating shaft. Its main function is to intermittently lift the shaking plate 51 by driving the cam and the rotating shaft to rotate through the motor. At the same time, the fin structure on the upper surface of the shaking plate 51 and the fin structure of the steam baffle 441 are staggered to comb the fibers for the last time, so that they enter the conveying component 2 of the refiner in a loose state, improving the paving effect. A steam baffle mounting frame 44 is fixedly installed above the side of the cooking tank 4 close to the output tank 5 by bolts. A steam baffle 441 is fixedly installed below the steam baffle mounting frame 44 by bolts. There are two groups of steam baffle mounting frames 44. The surfaces of the steam baffle 441 and the shaking plate 51 are evenly distributed with the same fin structure as the distribution fins 3441. The fin structure on the upper surface of the shaking plate 51 is staggered with the fin structure of one group of the steam baffles 441. A square sealing strip is arranged at the connection between the cooking tank 4 and the output tank 5. A conveying component 2 of the refiner is arranged on one side of the output tank 5. The steam baffle mounting frame 44 mainly functions to install the steam baffle 441. The steam baffle 441 mainly functions to block the upper area of the output end of the cooking tank 4 to avoid steam leakage, achieving the purpose of effectively recovering carbon disulfide, and at the same time guiding the water flow carrying the fibers downward so that they can enter above the conveying component 2 of the refiner.

[0025] Embodiment 6 Please refer to Figures 1 to 14 Based on Embodiment 5, this embodiment further proposes a method for using a viscose staple fiber cooking device, including the following steps: Step 1, the fibers enter above the dispersion guide plate 33 through the input pipe 311. The hot water inlet pipe 32 sprays the water flow through the spray branch pipe 321 and the dispersion spray flat nozzle 322, so that the water flow sprays out and generates a certain blocking impact with the scouring blocking strip 331, so that the fibers are washed away and flow and disperse to both sides along the scouring blocking strip 331, and the fibers are preliminarily dispersed; Step 2: The motor 341 drives the conveying roller 342 to rotate and drives the swing distributor 344 to swing left and right through the crank rocker assembly 343. When the swing distributor 344 swings, the distribution fins 3441 at its bottom are interlaced with the combing fins 332. Under the action of water flow, the fibers are evenly distributed. As the conveying roller 342 rotates, the fibers are dispersed and conveyed to above the transition deflector 35 through the dart-shaped fins 3421. The transition deflector 35 cooperates with the rotation of the dart-shaped fins 3421 to produce regular left and right swings, so that the water flow carries the fibers and is dispersedly conveyed to the fixing frame 43 for subsequent full steam cooking. Step 3: The steam sprayed by the steam nozzle 422 can pass through the steam tank 434 formed between the long guiding fins 433 to fully steam and loosen the fibers, so that the residual CS2 is fully cooked and removed. The rising steam carrying carbon disulfide can be connected to the condensation recovery and separation workshop through the carbon disulfide recovery pipe 411 for effective recovery of carbon disulfide. The carding frame net 435 is composed of spacer strips and thin cross strips to form a carding net, which cooperates with the steam sprayed by the steam nozzle 422 and the action of water flow, flushes and evenly combs the fibers, effectively improving the looseness of the fibers, reducing the yellow residue of carbon disulfide, narrowing the color difference of the finished product, and at the same time can intercept the broken fibers to avoid the blockage of the steam nozzle 422 caused by the accumulation of fiber clusters and affect the subsequent cooking effect. Step 4: The water flow carrying the fibers is deflected downward by the steam baffle 441 so that it can enter above the refining machine conveying assembly 2. The cam drive assembly 52 drives the shaking plate 51 to intermittently lift. At the same time, the fin structures on the upper surface of the shaking plate 51 and the fin structure of the steam baffle 441 are interlaced to comb the fibers for the last time, so that they enter the refining machine conveying assembly 2 in a loose state, improving the paving effect. The fibers that have been steamed and loosened are conveyed to the refining machine through the refining machine conveying assembly 2 for subsequent processing.
