Description

[0002] In the context of the rapid development of the textile and new material industries, lyocell fiber, as a kind of semi-synthetic fiber with excellent performance, is highly favored. It is made of natural cellulose such as wood pulp and cotton pulp through physical regeneration and forming processing. It not only has characteristics such as high strength, high modulus and high water absorption, but also has a soft and shiny hand feeling and appearance. It is widely used in the fields of textiles, clothing, medical supplies and sanitary materials.

[0003] In the process of lyocell fiber production, the solvent filtering link plays a key role in fiber quality and production stability. The industry generally uses filters to purify the solvent. Although this filtering method can meet the basic separation needs, in the continuous production process, the filter holes are easily blocked by impurity fibers, gel particles and other impurities, which leads to a decrease in filtering efficiency and insufficient solvent flow, affecting the forming quality of lyocell fiber and the production continuity. The workers need to regularly stop the machine, disassemble the filter and clean and maintain it. Not only is the operation process complicated and labor-intensive, but frequent shutdowns also lead to reduced production line efficiency and increased energy consumption, which restricts the economic benefits and production capacity of the enterprise.

The imported fiber solvent can be filtered by the processing module 2, and the processed solvent can be introduced into the next process for treatment through the mounting pipe 203. In the process of treatment, the position of the processing assembly 22 can be adjusted by the adjusting assembly 205, so that the inside of the single adjusting shell 2208 can be used for filtering treatment, and the inside of the other adjusting shell 2208 can be used for discharging impurity fibers.

[0030] In one embodiment of the present application, Figure 2 As shown, the mounting assembly may include a connection housing 201 , a controller 202 , a mounting tube 203 and a mounting housing 204 .

The controller 202 is arranged on one side of the connecting shell 201.

[0032] Specifically, the treated solvent can be introduced into the interior of the installation tube 203 through the installation shell 204 , and the treated solvent can be input into the next step for processing through the installation tube 203 .

[0033] In one embodiment of the present application, Figures 2-4 As shown, the processing assembly 22 may include a fixed shell 2201 , a partition 2206 , two adjustment shells 2208 , a rotating shaft 2211 and two spiral blades 2212 .

[0034] Among them, the fixed shell 2201 is fixedly connected to the inner wall of the connecting shell 201, the partition 2206 is slidably connected to the inner wall of the fixed shell 2201, and the two adjusting shells 2208 are respectively fixedly connected to the two sides of the partition 2206 and are symmetrically distributed. The surface of the adjusting shell 2208 is provided with evenly distributed filter holes 2210, and the rotating shaft 2211 is arranged at the axis center of the partition 2206, and the two ends respectively pass through the two adjusting shells 2208 and are rotatably connected to the inner wall of the adjusting shell 2208. The two spiral blades 2212 are both fixedly connected to the surface of the rotating shaft 2211 and are respectively located inside the two adjusting shells 2208. The diameter of the adjusting shell 2208 is smaller than the diameter of the partition 2206, and the spiral directions of the two spiral blades 2212 are opposite.

[0035] Specifically, the solvent to be processed can be introduced into the interior of the regulating shell 2208, and under the action of the filter hole 2210, the solvent can pass through normally, while the fiber impurities are retained in the interior of the regulating shell 2208, and the spiral blade 2212 can be driven to rotate synchronously through the rotating shaft 2211. During the rotation of the spiral blade 2212, the retained impurities can be gradually transported away from the partition 2206.

[0036] In one embodiment of the present application, Figures 2-4 As shown, the surface of the fixed shell 2201 is slidably connected with two symmetrically distributed slip rings 2202, and the opposite ends of the two slip rings 2202 are fixedly connected with baffles 2203. The end of the adjusting shell 2208 away from the partition 2206 is fixedly connected to the surface of the adjacent baffle 2203, and the surface of one of the baffles 2203 is provided with a motor 2204. One end of the rotating shaft 2211 is fixedly connected to the output shaft surface of the motor 2204. The surface of the adjusting shell 2208 is provided with a discharge cavity connected to the inner side of the slip ring 2202, and the surface of the slip ring 2202 is provided with a through hole 2213.

[0037] Specifically, the impurities transported by the spiral blades 2212 can be discharged through the discharge cavity and the through hole 2213, and the setting of the motor 2204 can drive the rotating shaft 2211 to rotate by starting the motor 2204, thereby realizing the transportation of the impurity fibers. In the process of transporting impurities, the spiral blades 2212 can squeeze the impurity fibers and further squeeze out the solvent in the impurity fibers. The setting of the baffle 2203 can prevent the impurity fibers from being directly pushed out, and can ensure that the impurity fibers can only be discharged through the discharge cavity and the through hole 2213. In addition, by setting the slip ring 2202, the position of the slip ring 2202 can be adjusted, thereby changing the synchronous movement of the baffle 2203 connected thereto. In this process, the adjustment shell 2208 and the partition 2206 are used to drive the slip ring 2202 and the baffle 2203 on the other side to move synchronously.

[0038] In one embodiment of the present application, Figures 2-4As shown, the top of the fixed shell 2201 is provided with two symmetrically distributed inlet ports 2205, and the bottom of the fixed shell 2201 is fixedly connected with two symmetrically distributed conduits 2209, the other end of the conduit 2209 being in communication with the mounting shell 204.

[0039] Specifically, the filtered solvent can be introduced into the inside of the mounting shell 204 through the conduit 2209, and finally introduced into the next process for processing through the mounting pipe 203.

[0040] In an embodiment of the present application, as shown in Figures 2-4 , the top of the adjusting shell 2208 is fixedly connected with two symmetrically distributed inlet pipes 2207, the upper end of the inlet pipe 2207 being in communication with the inlet port 2205.

[0041] Specifically, the inlet pipe 2207 is used to introduce untreated solvent into the inside of the adjusting shell 2208, and the inner hole of the inlet pipe 2207 is provided with a waist-shaped hole, which ensures that the inlet pipe 2207 can normally introduce solvent into the inside of the adjusting shell 2208 during the movement of the adjusting shell 2208.

[0042] In an embodiment of the present application, as shown in Figures 2-4 , the both sides of the partition plate 2206 are provided with mounting grooves, the inside of the mounting groove is provided with a pressure sensor 2215, and the surface of the pressure sensor 2215 is provided with a diaphragm 2214.

[0043] Specifically, as the impurities in the adjusting shell 2208 increase, the difficulty of filtering the solvent will gradually increase, and as the filtering difficulty increases, the pressure in the adjusting shell 2208 will gradually increase, so that the diaphragm 2214 exerts pressure on the pressure sensor 2215, and when the pressure sensor 2215 detects that the pressure exceeds the threshold value, the signal is transmitted to the controller 202.

[0044] In an embodiment of the present application, as shown in Figure 1 , Figure 2 and Figure 6 , the collection assembly 21 can include a collection shell 2101, an outlet pipe 2103, a sealing block 2104, and a connecting rod 2105.

[0045] The collecting shell 2101 is arranged on the surface of the connecting shell 201, and the top of the collecting shell 2101 is provided with a connecting port 2102, one end of a discharge pipe 2103 is threadedly connected with the inner wall of the connecting port 2102, the upper end of the discharge pipe 2103 penetrates through the connecting shell 201 and the slip ring 2202 and is connected with the through hole 2213, a sealing block 2104 is slidingly connected with the inner wall of the collecting shell 2101, a connecting rod 2105 is fixedly connected with the bottom of the sealing block 2104, and the lower end of the connecting rod 2105 penetrates through the collecting shell 2101 and is fixedly connected with a push block 2106.

[0046] Specifically, the impurity fibers discharged through the discharge cavity and the through hole 2213 can be discharged through the discharge pipe 2103, and under the flow guiding of the discharge pipe 2103, the impurity fibers are injected into the inside of the collecting shell 2101 for storage, and as the amount of the impurity fibers injected into the inside of the collecting shell 2101 increases, the sealing block 2104 is pressed and pushed downward along the collecting shell 2101.

[0047] In an embodiment of the present application, as shown in Figure 5 The adjusting assembly 205 can include a sliding shell 2051, a push rod 2053, an electric push rod 2056 and a communicating shell 2057.

[0048] The communicating shell 2057 is fixedly connected with the inner wall of the connecting shell 201, and the upper end of the communicating shell 2057 penetrates out of the connecting shell 201, the sliding shell 2051 is slidingly connected with the inside of the communicating shell 2057, the top of the sliding shell 2051 is provided with a communicating port 2052, the sliding shell 2051 is connected with the feeding pipe 1 through the communicating port 2052, the electric push rod 2056 is arranged on one side of the communicating shell 2057, the output shaft of the electric push rod 2056 penetrates through the communicating shell 2057 and is fixedly connected with the surface of the sliding shell 2051, the push rod 2053 is fixedly connected with the other side of the communicating shell 2057, and the other end of the push rod 2053 penetrates out of the communicating shell 2057 and is fixedly connected with the surface of the adjacent baffle 2203, the bottom of the communicating shell 2057 is provided with two discharge holes 2055 which are connected with the inlet 2205, and the bottom of the sliding shell 2051 is provided with two symmetrical butt joints 2054, one of which is connected with the adjacent discharge hole 2055.

[0049] Specifically, when the pressure sensor 2215 detects that the pressure exceeds the threshold value, a signal is transmitted to the controller 202, the controller 202 starts the electric push rod 2056 to push the sliding shell 2051 to move, in the process, the communication state of the butt joint 2054 and the discharge hole 2055 can be changed, and in the process, the push rod 2053 connected with the baffle 2203 can be driven by the sliding shell 2051 to move synchronously, thereby achieving the effect of changing the position of the adjusting shell 2208.

[0050] The communication port 2052 can guide the solvent in the feed pipe 1 into the interior of the sliding shell 2051, the solvent in the interior of the sliding shell 2051 is discharged through the communication of the docking hole 2054 and the discharge hole 2055, and finally guided into the interior of the adjusting shell 2208 through the guide inlet 2205 and the guide pipe 2207 for processing.

[0051] By changing the communication state of the docking hole 2054 and the discharge hole 2055, and by changing the position of the adjusting shell 2208, the interior of one of the adjusting shells 2208 can be used for the filtering treatment of the solvent, and the communication state of the adjusting shell 2208 and the through hole 2213 is cut off by the fixed shell 2201, so that the impurity fibers are not discharged through the through hole 2213, and the interior of the other adjusting shell 2208 is not used for processing the solvent at this time, and the movement of the sliding ring 2202 connected thereto can no longer block the communication state of the through hole 2213 and the discharge cavity by the fixed shell 2201, at this time the interior of the collection shell 2101 connected thereto can be guided into the storage through the through hole 2213 and the guide pipe 2103.

[0052] In one embodiment of the present application, as shown in Figure 1 and Figure 5 The auxiliary assembly 3 can include an injection pipe 301, a filter screen 302, and a one-way valve 303.

[0053] The injection pipe 301 is in communication with the surface of the feed pipe 1, the filter screen 302 is detachably arranged in the interior of the injection pipe 301, the one-way valve 303 is arranged in the interior of the injection pipe 301 and located between the feed pipe 1 and the filter screen 302, and the outer diameter of the collection shell 2101 is equal to the inner diameter of the opening of the injection pipe 301 away from the feed pipe 1.

[0054] Specifically, since one end of the guide pipe 2103 is threadedly connected with the inner wall of the connecting port 2102, the collection shell 2101 can be separated from the guide pipe 2103 by rotating and detaching, and the collection shell 2101 is inserted into the interior of the injection pipe 301, the stored impurity fibers of the collection shell 2101 are discharged under the action of the connecting rod 2105 by pushing the push block 2106, and in this process most of the impurity fibers can be extruded by the inner wall of the collection shell 2101, so that the residual solvent in the impurity fibers is extruded and discharged through the connecting port 2102 along with part of the impurity fibers, and part of the impurity fibers can be intercepted by cooperating with the filter screen 302, and the solvent can be extruded and pushed to pass through the one-way valve 303 and be guided back into the interior of the feed pipe 1, realizing the recycling of the residual solvent.

[0055] Specifically, the overall working process of the present application is as follows: Solvent introduction stage: the filtered lyocell fiber solvent enters the sliding shell 2051 of the adjusting assembly 205 through the feed pipe 1, is introduced into the inside of the adjusting shell 2208 on one side of the processing assembly 22 through the cooperation of the communication port 2052, the butt joint hole 2054 and the discharge hole 2055, the guide inlet 2205 and the guide pipe 2207.

[0056] Filtering treatment stage: the filter holes 2210 on the surface of the adjusting shell 2208 intercept the impurity fibers in the solvent, the filtered clean solvent passes through the filter holes 2210, enters the mounting shell 204 through the guide pipe 2209, and is transported to the next process through the mounting pipe 203 and the connecting flange 101.

[0057] Blockage detection and adjustment stage: when the impurity fibers accumulated in the adjusting shell 2208 cause the pressure to rise, the pressure sensors 2215 (sensing pressure through the diaphragm 2214) on both sides of the partition plate 2206 transmit signals to the controller 202, the controller starts the electric push rod 2056 to push the sliding shell 2051 to move, switches the communication state of the butt joint hole 2054 and the discharge hole 2055, and moves the processing assembly 22 as a whole through the push rod 2053, so that the original filtering side adjusting shell 2208 switches to the cleaning position, and the other side adjusting shell 2208 switches to the filtering position, realizing alternating operation.

[0058] Impurity discharge and collection stage: in the cleaning position of the adjusting shell 2208, the motor 2204 drives the rotating shaft 2211 to rotate, and the impurity fibers are pushed to the discharge cavity through the spiral blade 2212 (reverse spiral), and then are sent into the collection shell 2101 of the collection assembly 21 through the through hole 2213 of the slip ring 2202 and the discharge pipe 2103, and the impurity pushing sealing block 2104 moves downward to store.

[0059] Residual solvent recovery stage: the collection shell 2101 is disassembled and connected to the injection pipe 301 of the auxiliary assembly 3, the pushing block 2106 is pushed to make the sealing block 2104 move upward to extrude the impurity fibers, and the residual solvent passes through the filter screen 302 and the one-way valve 303 to return to the feed pipe 1, realizing solvent recycling.

[0060] In summary, the lyocell fiber solvent filtering device of the embodiment of the application can realize self-cleaning of the filter holes without stopping through alternating operation, and the residual solvent in the impurity fibers is recovered by cooperating the collection assembly and the auxiliary assembly, which improves the filtering efficiency and the utilization rate of the solvent.
