Description

Technical Field

[0001] The utility model relates to the technical field of fiber refiners and is a water washing device for a fiber refiner. Background Art

[0002] Viscose fiber is the full name of viscose fiber. It is a cellulose fiber obtained by extracting and reshaping the fiber molecules from natural wood cellulose using "wood" as the raw material. Its preparation process is as follows: plant cellulose is alkalized to form alkali cellulose, which is then reacted with carbon disulfide to form cellulose xanthate. The viscous solution obtained by dissolving it in a dilute alkali solution is called viscose. Viscose fiber is obtained after wet spinning and a series of treatment processes.

[0003] Viscose fiber is produced under constant temperature and humidity conditions. After viscose staple fibers are spun and formed, they must be thoroughly post-processed. At present, most domestic factories use the post-processing method of staple fibers, that is, after cutting the fiber strips, the fibers are spread on a long-net refiner, and the cotton-like fibers are driven by the metal mesh belt of the refiner to move forward continuously. When the fiber layer moves forward, the overflow leaching tank is mainly used to rinse the fibers running on the mesh belt to remove impurities. The refiner mainly relies on the leaching tank to evenly distribute the leaching liquid and flow out, so as to achieve the best leaching effect.

[0004] The Chinese patent document with the announcement number CN205669114U discloses a refining machine spray system, which includes a water tank, a spray tank, and a spray liquid distributor is arranged at the bottom of one end of the spray tank. The spray liquid distributor is a rectangular box, and the height of the spray liquid distributor is less than the height of the spray tank. The two ends of the spray liquid distributor are respectively provided with a spray liquid inlet and a spray liquid outlet, and the spray liquid inlet is connected to the lower opening of the water tank. The top surface of the spray liquid distributor is provided with a spray liquid outlet hole, and the opening of the spray tank is a zigzag opening. Since the opening of the above-mentioned spray tank is a zigzag opening, its distribution effect on the liquid flow is not continuous. After the elution liquid overflows, it will form a stream of liquid, and it is impossible to form a uniform and continuously distributed liquid waterfall. It is difficult for an overflow elution tank to evenly clean the fiber.

[0005] Typically, multiple levels of leaching tanks are set up at intervals along the metal mesh belt of the refiner so that uniform cleaning can be achieved through repeated liquid flows that overlap each other. However, multiple overflow cleaning tanks will inevitably consume more cleaning liquid, and it is difficult to determine whether the cleaning liquid flowing out of the zigzag opening can form a uniformly distributed flushing liquid on the fiber layer. In addition, the liquid flow flowing out of the overflow leaching tank mainly falls naturally due to gravity. After the above liquid flow enters the fiber layer, its penetration into the fiber layer is limited, making it difficult to effectively clean the bottom fibers (fibers on the side that contacts the metal mesh belt). Summary of the invention

[0006] The utility model provides a fiber refiner water washing device, which overcomes the deficiencies of the above-mentioned prior art and can effectively solve the problems that the multi-stage overflow leaching tanks in the existing refiner water washing device consume a large amount of cleaning liquid, and it is difficult to ensure that the overflowing cleaning liquid flow can continuously and evenly rinse the fibers; the penetration degree of the fiber layer is limited, and it is difficult to effectively clean the bottom fiber.

[0007] The technical solution of the utility model is achieved through the following measures: a fiber refining machine water washing device, including at least one stage of spray cleaning mechanism, the spray cleaning mechanism includes a spray manifold, a nozzle, a first liquid inlet pipe, a second liquid inlet pipe and a rotary joint, the lower part of the spray manifold is connected and installed with at least five nozzles with partially overlapping spray areas at front and rear intervals, the front end of the spray manifold is connected and installed together with the upper end of the first liquid inlet pipe, the lower end of the first liquid inlet pipe is connected and installed with a rotary joint that can make the spray manifold rotate left and right in the horizontal direction, and the lower end of the rotary joint is connected and installed with the second liquid inlet pipe.

[0008] The following are further optimizations and / or improvements to the above utility model technical solution:

[0009] The nozzle may be a fan-shaped nozzle, and the spray fan angle may be 0°-150°.

[0010] The spraying pressure of the above nozzle can be 1.5 kg / cm 2 Up to 7 kg / cm 2 .

[0011] The installation axes of the two adjacent nozzles may be staggered, and the installation axes of the two nozzles that are alternately arranged may be in the same plane.

[0012] The above-mentioned spray cleaning mechanism may also include a liquid inlet control valve, an overflow trough, a third liquid outlet pipe and a fourth liquid outlet pipe. An overflow trough with an opening facing upward is provided on the left side of the spray collecting pipe. The upper ends of the left and right walls of the overflow trough are provided with serrated grooves for guiding the outflow of the eluent. A third liquid inlet pipe inclined in a shape of lower back and higher front is provided on the upper side of the front end of the overflow trough. The upper end of the third liquid inlet pipe is connected and installed with a fourth liquid inlet pipe. The rear side of the upper part of the fourth liquid inlet pipe is fixedly installed together with the middle part of the front side of the overflow trough, and the lower part of the fourth liquid inlet pipe is connected and installed together with the second liquid inlet pipe; the middle parts of the second liquid outlet pipe and the fourth liquid outlet pipe are both provided with a liquid inlet control valve.

[0013] The above may also include a fiber refining machine, which includes a frame, a metal mesh belt, a liquid inlet manifold and a dewatering roller group. A metal mesh belt that can move continuously to the right is provided in the middle of the frame. At least one group of dewatering roller groups that can squeeze out moisture from the fiber layer are provided at intervals on the left and right of the frame corresponding to the position of the metal mesh belt. Two-stage spray cleaning mechanisms are fixedly installed at intervals on the left and right of the front end of the frame corresponding to the right position of each group of dewatering roller groups. A liquid inlet manifold is provided on the frame corresponding to the position below the metal mesh belt, and the liquid inlet end of each stage of the spray cleaning mechanism is connected to the liquid inlet manifold and installed together.

[0014] The utility model has a reasonable and compact structure and is easy to use. Through the spray manifold that can rotate left and right in the horizontal direction and the fan-shaped nozzles arranged at intervals in front and behind the spray manifold, the high-pressure cleaning liquid can be pressurized to form a high-pressure cleaning liquid spray, so that the cleaning liquid can penetrate into the underlying fiber layer and effectively remove the attachments on the surface of the underlying fibers; the spraying areas of the nozzles distributed on the spray manifold overlap to a certain extent, so that the sprayed high-pressure water mist can form a high-pressure water curtain that is compatible with the width of the metal mesh belt and is uniform and continuous, so that all fibers within the width range can be completely covered by one spray, and as the metal mesh belt moves forward, the fiber cloth on the metal mesh belt is completely, continuously and evenly washed, which greatly reduces the number of cleaning times and saves the use of cleaning liquid, thereby saving water and electricity and having higher economic benefits. At the same time, it can also reduce the number of spray mechanisms set up and save costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention is not limited by the following embodiments, and specific implementation methods can be determined according to the technical solution of the present invention and actual conditions.

[0020] In the present invention, for the convenience of description, the relative position relationship of each component is described according to the attached manual. Figure 1 The positional relationships such as front, back, top, bottom, left, and right are described according to the layout directions of the drawings in the specification.

[0021] The present invention is further described below in conjunction with the embodiments and drawings:

[0022] Embodiment 1: As attached Figure 1-3 As shown, the fiber refining machine water washing device includes at least one stage of spray cleaning mechanism, which includes a spray header 1, a nozzle 2, a first liquid inlet pipe 3, a second liquid inlet pipe 4 and a rotary joint 5. At least five nozzles 2 with partially overlapping spray areas are installed at intervals in the front and rear of the lower part of the spray header 1. The front end of the spray header 1 is connected and installed together with the upper end of the first liquid inlet pipe 3. The lower end of the first liquid inlet pipe 3 is connected and installed with a rotary joint 5 that can rotate the spray header 1 left and right in the horizontal direction. The lower end of the rotary joint 5 is connected and installed with the second liquid inlet pipe 4.

[0023] During use, at least one level of spray cleaning mechanism can be arranged at intervals along the metal mesh belt 11 of the long-net refiner, and then the cleaning liquid is pumped into the spray collection pipe 1 through the second liquid inlet pipe 4 and the first liquid inlet pipe 3 by a high-pressure pump, and then the high-pressure cleaning liquid is pressurized and sprayed on the fiber layer 14 through the nozzle 2. The droplet-shaped high-pressure cleaning liquid can impact and rinse the fiber layer 14 through pressure, and fully rinse the fibers so as to rinse away excess acidic impurities and other attachments contained in the fibers; the high-pressure cleaning liquid has good penetrability under the action of pressure, and can better penetrate the fiber layer 14, so that the bottom fiber can also be fully rinsed, effectively improving the fiber cleaning effect.

[0024] The spray header 1 can be rotated left and right in the horizontal direction by the rotary joint 5, and the angle between the spray header 1 and the advancing direction of the fiber layer 14 can be manually adjusted so that the spray header 1 can better rinse the fiber. The nozzles 2 with partially overlapping areas in the multiple spray regions 20 can make the sprayed high-pressure cleaning liquid completely cover the fiber layer 14 along the direction of the spray header 1 (i.e. the width of the metal mesh belt or the width of the fiber layer). During the advancement of the metal mesh belt 11, it is ensured that the fiber layer in the width direction can be rinsed by one spray, which greatly reduces the number of cleaning times and the amount of cleaning liquid used, thereby saving more water and electricity, and having higher economic benefits. At the same time, it can also reduce the number of spray mechanisms and save costs.

[0025] According to the requirements, the length of the spray header 1 is adapted to the width of the metal mesh belt, and the height between the spray header 1 and the fiber layer 14, the number of nozzles 2, the type of nozzles 2 and the spray angle can be adjusted according to the actual requirements; the spray header 1 and the nozzles 2 can be detachably installed to facilitate the replacement and maintenance of the nozzles 2; when the water contains impurities, a butterfly nozzle with a built-in brush (such as Figure 2 As shown), to avoid impurities affecting the spray flushing effect; the rotary joint 5 is a movable joint in the prior art that can enable two sections of rigid pipes to rotate continuously at a low speed. Its interior is supported by a rotating bearing, and the sealing between the joints is achieved by a special seal. It can be a straight rotary joint or a right-angle elbow rotary joint; the rotary joint 5 can also be realized by a motor in conjunction with a reciprocating swing mechanism in the prior art, so that the automatic swing of the spray header 1 can be controlled by a controller to achieve a better spray effect.

[0026] The above-mentioned fiber refiner washing device can be further optimized and / or improved according to actual needs:

[0027] Embodiment 2: As attached Figure 2 As shown, the nozzle 2 is a fan-shaped nozzle, and the spray fan angle is 0°-150°.

[0028] The fan-shaped nozzle in the prior art is a nozzle 2 with a fan-shaped spray shape. Its fan-shaped spray form makes the edge of the spray shape very clearly defined, and its finely processed guide plane can provide a uniform, high-impact spray so that the cleaning liquid has stronger penetration, thereby being able to better rinse and clean the bottom layer of fibers on the metal mesh belt 11, and better control the overlap of the spraying area to ensure that the fiber layer in the width direction can be completely flushed.

[0029] According to demand, in order to obtain a better spraying effect, the spray fan angle of the fan nozzle can be adjusted or replaced according to actual needs. For thicker and denser fiber layers 14, a 0° spray nozzle 2 can also be used to form a high-pressure liquid injection spray to completely and thoroughly clean the inside of the fiber.

[0030] In this embodiment, a standard fan-shaped nozzle can be used, which can produce a high-impact liquid column flow or fan-shaped spray, and the spray fan angle is α (jet angle) is 0°-110°, and the generated spray is evenly distributed, the droplet size is small to medium, and when several nozzles are required to produce overlapping spray, the characteristic gradually tapering spray edge makes the spray coverage area evenly distributed; this embodiment can also use a W-shaped wide-angle fan nozzle (such as Figure 1 As shown in the figure), the spray fan angle is 50°-130°, the flow distribution is uniform, and effective spray coverage can be formed at a lower pressure. The inside of the spray hole is smooth and unobstructed, with excellent anti-clogging performance and more energy saving.

[0031] Example 3: The spraying pressure of nozzle 2 is 1.5 kg / cm 2 Up to 7 kg / cm 2 .

[0032] During use, the flow specifications of nozzle 2 in the prior art are also varied. Under a pressure of 1.5-7 kg, the flow rate of nozzle 2 can quickly increase from 1 liter / minute to 75 liters / minute; since the cleaning liquid itself is pressurized, the cleaning liquid flow has stronger penetrating power after being pressurized and sprayed by nozzle 2, and can better rinse and wash the bottom fibers and quickly remove attachments on the fiber surface.

[0033] Embodiment 4: The installation axes of two adjacent nozzles 2 are staggered, and the installation axes of two alternately distributed nozzles 2 are in the same plane.

[0034] This setting is mainly based on the fact that the spraying area of ​​the nozzle 2 requires a certain degree of overlap, usually 25%-30%, but the overlap of the spraying area 20 will affect the impact force of the spray. Therefore, the installation position of the nozzle 2 can be adjusted to ensure that all fiber layers 14 in the width direction can be fully covered and rinsed at one time, while avoiding the overlap area affecting the spray impact force.

[0035] According to the needs, when the nozzle 2 selects a standard fan nozzle or other direct current nozzle, two groups of nozzles can be arranged at intervals on the left and right, and the spraying areas of each group of nozzles 2 do not overlap, while there is a certain overlap area 21 in the spraying areas between the two nozzles 2 on the left and right; when the nozzle 2 selects a W-shaped wide-angle fan nozzle, it is also possible to ensure that the showering area has a certain overlap without affecting the impact force of the spray by arranging two groups of nozzles 2 symmetrically on the left and right, or selecting two groups of nozzles 2 with different deflection angles, or selecting two groups of nozzles 2 with different lengths.

[0036] In this embodiment, a fan-shaped nozzle 2 with a spray fan angle of 100° can be selected. In order to avoid interference between the spray planes in the same plane, two adjacent nozzles 2 should be installed with their center lines staggered, and it is preferable that the nozzles 2 at alternate positions are in the same plane.

[0037] Embodiment 5: As attached Figure 1 , 3 As shown, the spray cleaning mechanism also includes a liquid inlet control valve 6, an overflow trough 7, a third liquid outlet pipe 8 and a fourth liquid outlet pipe 9. An overflow trough 7 with an opening facing upward is provided on the left side of the spray collecting pipe 1. The upper ends of the left and right walls of the overflow trough 7 are provided with serrated grooves for guiding the outflow of the eluent. A third liquid inlet pipe inclined in a shape of lower back and higher front is provided on the upper side of the front end of the overflow trough 7. The upper end of the third liquid inlet pipe is connected and installed with a fourth liquid inlet pipe. The rear side of the upper part of the fourth liquid inlet pipe is fixedly installed together with the middle part of the front side of the overflow trough 7, and the lower part of the fourth liquid inlet pipe is connected and installed together with the second liquid inlet pipe 4; the middle parts of the second liquid outlet pipe and the fourth liquid outlet pipe 9 are both provided with a liquid inlet control valve 6.

[0038] By configuring in this way, the device can have two working modes: a spray cleaning mode and an overflow cleaning mode.

[0039] During use, by adjusting the on / off status of the two liquid inlet control valves 6, the overflow cleaning mode and the spray cleaning mode can be quickly switched according to actual needs, thereby making the device more convenient to use and having a wider range of applications.

[0040] Embodiment 6: As attached Figure 1 , 3 As shown, it also includes a fiber refining machine, which includes a frame 10, a metal mesh belt 11, a liquid inlet manifold 12 and a dewatering roller group 13. A metal mesh belt 11 that can move continuously to the right is provided in the middle of the frame 10, and at least one group of dewatering roller groups 13 that can squeeze out moisture from the fiber layer 14 are provided on the left and right sides of the frame 10 corresponding to the position of the metal mesh belt 11. Two-stage spray cleaning mechanisms are fixedly installed on the left and right sides of the front end of the frame 10 corresponding to the right position of each group of dewatering roller groups 13, and a liquid inlet manifold 12 is provided on the frame 10 corresponding to the position below the metal mesh belt 11. The liquid inlet end of each stage of the spray cleaning mechanism is connected to the liquid inlet manifold 12 and installed together.

[0041] During use, the metal mesh belt 11 can carry the fiber layer 14 forward together. When the two rollers in the dewatering roller group 13 roll over the fiber layer 14, the fibers filled with water after spray cleaning can be quickly squeezed dry, so that some attachments on the fibers can be squeezed out along with the water, thereby accelerating the cleaning speed of the fibers and achieving the purpose of saving cleaning liquid; the liquid inlet manifold 12 can uniformly provide high-pressure cleaning liquid for the cleaning mechanism of the spray collection pipe 1.

[0042] As required, a fiber feeding port 15 is provided at the left end of the fiber refining machine to facilitate the insertion of fibers; in this embodiment, nine nozzles 2 are provided on the spray manifold 1 at front and rear intervals; four groups of dewatering roller groups 13 capable of squeezing out moisture from the fiber layer 14 are provided on the frame 10 at left and right intervals, and each group of dewatering roller groups 13 includes two dewatering rollers symmetrically distributed up and down along the metal mesh belt 11, and the active rollers of the dewatering rollers can be driven by a control motor; the four groups of dewatering roller groups 13 divide the refiner into four-level cleaning areas 19, namely a primary cleaning area 16, a secondary cleaning area 17, a tertiary cleaning area 18 and a fourth cleaning area 19, and two-level spray cleaning mechanisms are provided in each cleaning area at left and right intervals, and the fourth liquid inlet pipe of each spray cleaning mechanism is connected to the liquid inlet manifold 12.

[0043] The above technical features constitute the embodiments of the present utility model, which have strong adaptability and implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
