Description

  The present invention relates to a pretreatment device for fiber material. In particular, a fiber provided with a liquid agent circulation device having a liquid agent supply device for transferring the liquid agent into the working area, a collection tray for the liquid agent that has not been absorbed, and a pump device for transferring the liquid agent from the storage container to the liquid agent supply device The present invention relates to a material pretreatment apparatus.

  An example of a pretreatment device in which fiber materials existing in the form of yarns arranged adjacent to each other are prepared for sizing agent application will be described below.

  In “pre-wetting”, water is basically used as a liquid agent, and this water is applied to the fiber material. The fiber material is guided through the work area. This work area is composed of, for example, a plurality of cylinders or drums in which fiber materials are arranged. Also, an excessive amount of solution is used to achieve complete wetting of the fiber material. That is, not all of the water is absorbed by the fiber material, but a portion of the water drops into the collection dish. However, the water dripping into the collection dish is accompanied by loose parts of the fiber material and is contaminated thereby. Further, at this time, for example, loose parts such as fluff are mixed in the collection dish, and it is difficult to reuse the liquid agent in the collection dish. For this reason, in general, the liquid agent in the collection dish requires relatively time-consuming purification or filtration.

  This invention is made | formed in view of said problem, The objective is to provide the pre-processing apparatus for fiber materials which can further utilize the liquid agent which became excessive easily.

  The problem is that, in the pretreatment device of the type mentioned at the beginning, this collecting plate overflows via an outflow part that branches off from the collecting plate at a predetermined distance downward from the upper edge of the collecting plate. The overflow pipe may include an overflow portion, and the overflow portion may be achieved by a configuration in which the overflow portion is combined with the storage container.

  In the configuration described above, the contaminant introduced to the liquid agent can be regarded as being composed of floating particles. That is, it can be assumed that this contaminant remains on the surface of the liquid agent. However, the liquid below this surface is clean enough to be used again. In other words, when the portion below the surface of the liquid agent is diverted from the collection dish, the diverted liquid agent does not contain floating contaminated particles and can be used continuously.

  The overflow pipe has a drain outlet at the upper end thereof, and this drain outlet is arranged at the same height as the upper edge of the collecting tray. And it is preferable to comprise so that a communicating pipe may be formed with this overflow pipe and a collection tray. In the communication pipe, the liquid agent is always at the same height (relative to the vertical direction). If the liquid is continuously supplied to the collecting tray, the liquid will overflow sooner or later. When the liquid overflows, floating contaminant particles are mixed beyond the upper edge of the collection dish. As a result, it is possible to prevent an excessive amount of contaminant particles from accumulating in the collection dish. On the other hand, the liquid agent coming out of the overflow pipe is taken out from a region below the surface of the liquid agent in the collection dish, and thus does not contain these contaminant particles.

  Moreover, it is preferable that an overflow pipe | tube has an overflow pipe | tube edge part which can adjust height. The overflow pipe end defines the height of the drainage port with respect to the vertical direction. The height-adjustable overflow tube end allows the position of the drain to be changed somewhat relative to the height position of the upper edge of the collection tray. At that time, the drainage port is basically maintained at the same height as the upper edge of the collection dish. However, by adjusting the height of the end of the overflow tube, the amount of liquid that can flow out beyond the upper edge of the collection dish can be controlled, in other words. That is, if the end of the overflow tube is set to be slightly higher than the upper edge of the collection dish, the amount of liquid flowing out of the collection dish beyond the upper edge of the collection dish will be increased accordingly, In response, a large proportion of pollutants will also escape. On the other hand, if the overflow pipe end is set somewhat lower, the amount of liquid that flows out of the collection tray beyond the upper edge of the collection tray will be reduced accordingly, and therefore the contaminants that flow out accordingly will also be reduced. Less. However, at this time, less “lost” solution is also present. Depending on the height setting of the end of the overflow pipe, the liquid agent circulation device can be adjusted to different types of fiber materials. In other words, if there is a fiber material that contains more pollutants than another fiber material and contains a lot of pollutants, the height of the overflow pipe end will be higher than that of a fiber material that contains less pollutants. Is positioned.

  Moreover, it is preferable that an overflow pipe is equipped with the screw bush at the upper end part. In the case of the configuration including the screw bush as described above, the height position of the end portion of the overflow pipe can be adjusted by rotating the screw bush on the overflow pipe. This adjustment can be made very delicately because the bush is screwed to the overflow tube.

  Moreover, it is preferable that the collection dish is provided with a floor portion, and the outflow portion is arranged on the floor portion. According to this configuration, as long as the liquid is in the collection dish, it is actually impossible for floating contaminant particles to reach together in the overflow tube. Since the liquid agent is always taken out from the floor region, so to speak, continuous circulation of the liquid agent can be achieved in the collection dish.

  Moreover, the overflow pipe | tube may be comprised so that it may be arrange | positioned on the outer side of a collection tray. By comprising in this way, it becomes easy to collect the liquid agent which flows out from an overflow pipe, and to supply to a storage container.

  Further, the collection tray may include a dish overflow portion, and the dish overflow portion may be configured to be coupled to the contaminant removal device. The dish overflow section receives liquid that has flowed beyond the upper edge of the collection dish and is therefore filled with contaminant particles. These contaminant particles can then be removed from the liquid by the contaminant removal device.

  Further, the contaminant removing device may include a filter device, and the filter device may be configured to be coupled to the storage container. This filter device is a simple device for removing contaminant particles from the liquid agent. At the outlet of the filter device, the liquid agent is purified to the extent that it can be supplied again to the liquid agent supply device, and can be reused.

  Preferably, the storage container may be configured to include an inflow portion having a liquid level adjuster (Fuellstandsregelung) and a first volume flow sensor. According to this configuration, it is possible to approximately determine how much liquid agent has reached the fiber material. And since the ratio of the liquid agent supplied from the collection dish via the overflow pipe can be taken into consideration, the liquid level adjusting unit ensures that too much liquid agent is not replenished in the storage container. be able to. That is, the volume flow sensor can determine how much liquid is replenished.

  In this case, it is preferable that the dish overflow portion is configured to include the second volume flow sensor. By providing this second volume flow sensor, it is possible to determine the proportion of the liquid agent that flows out beyond the upper edge of the collection dish. Then, the ratio of the liquid agent is subtracted from the volume flow rate determined to reach the storage container via the inflow portion. In that case, this difference is basically the amount of liquid absorbed by the fiber material.

  The present invention also relates to a liquid agent circulating apparatus for use in the fiber material pretreatment apparatus as described above.

  The pretreatment device for fiber material according to the present invention is configured as described above, and has an effect that the excess liquid agent can be further utilized easily.

BRIEF DESCRIPTION OF THE DRAWINGS It is the schematic which shows embodiment of this invention and shows the principal part structure of the pre-processing apparatus for fiber materials. FIG. 2 is an enlarged detail view of the fiber material pretreatment device shown in FIG. 1.

  Hereinafter, based on a preferred example, a configuration of a fiber material pretreatment apparatus (hereinafter, pretreatment apparatus) 1 according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows a pretreatment device 1 as used in the form of a prewetting device for a fiber material 2. The fiber material 2 here is provided in the form of yarns arranged adjacent to each other. By the way, prewetting is used for preparation of sizing agent application, for example. When performing this prewetting, the fiber material 2 is supplied through the first drum 3. The first drum 3 forms a nip (working area) 5 together with the second drum 4 and is guided so that the fiber material 2 passes through the nip 5. Similarly, the second drum 4 and the third drum 6 form a nip 7, and the fiber material 2 is guided through this nip (working area) 7. A first injection spray device (liquid supply device) 8 is disposed at the inlet of the nip 5, and a second injection spray device (liquid agent supply device) 9 is disposed at the inlet of the second nip 7. A liquid agent 11 is supplied from a storage container 12 to the two spraying devices 8 and 9 by a pump (pump device) 10. For this purpose, the pump 10 is coupled to the spraying devices 8, 9 via the conduit 13.

  The storage container 12 includes a liquid level adjustment unit 14. The liquid level adjusting unit 14 is connected to the maximum sensor 15 and the minimum sensor 16. In addition, the liquid level adjusting unit 14 is configured so that the liquid level of the liquid 11 in the storage container 12 is always between the upper limit value set by the maximum sensor 15 and the lower limit value set by the minimum sensor 16. The injection valve (liquid level adjusting unit) 17 in the (inflow unit) 18 is operated.

  A first volume flow sensor 19 is provided on the surface or inside of the water pipe 18. The first volume flow sensor 19 calculates the volume flow rate of the liquid 11 supplied to the storage container 12.

  A slightly excessive liquid 11 is applied to the fiber material 2. For this reason, all the liquid agents 11 cannot be absorbed by the fiber material 2. Then, the remaining liquid agent 11 that is not absorbed by the fiber material 2, that is, the excess liquid agent 11 flows downward or is dripped downward, and is collected in the collection dish 20.

  The collection tray 20 has an outflow portion 21 disposed on the floor portion 22 of the collection tray 20. The outflow part 21 is coupled to an overflow pipe 24 disposed outside the collection tray 20 via a pipe line 23.

  Further, the collection dish 20 includes an upper edge 25. The liquid 11 that has flowed out of the collection tray 20 beyond the upper edge 25 similarly reaches the inside of the dish overflow portion 26 having at least one outflow portion 27. The outflow portion 27 is connected to the outflow pipe 28. Then, the second volume flow sensor 29 obtains the volume flow rate of the liquid 11 flowing out from the dish overflow portion 26 through the outflow pipe 28.

  As shown in FIG. 2, the overflow pipe 24 includes an overflow pipe end 30. The overflow pipe end 30 is arranged so as to be at the same height as the upper edge 25 of the collection tray 20 (relative to the vertical direction). Here, the “same height” should not be understood as a mathematically exact meaning. This is because a bush (screw bush) 31 screwed to the upper end of the overflow pipe 24 is disposed at the overflow pipe end 30 of the overflow pipe 24. In this regard, the thread 32 is illustrated schematically. When the bush 31 is rotated with respect to the overflow pipe 24, the height position of the overflow pipe end 30 changes. And this overflow pipe end part 30 will touch a drain outlet.

  The liquid agent flowing out beyond the overflow pipe end 30 reaches the overflow part 33 connected to the storage container 12.

  Further, the collection tray 20 and the overflow pipe 24 form a communication pipe system (communication pipe). In such a system, the liquid agent 11 becomes the same height everywhere. This same height is shown in FIG.

  The liquid agent that has reached the collection tray 20 without being absorbed by the fiber material 2 can leak out of the collection tray 20 again in two ways. That is, a part of the liquid agent 11 flows out beyond the upper edge 25 of the collection dish 20. In this process, at least some of the floating contaminant particles are also flowed together over the upper edge 25 and into the dish overflow portion 26. The other liquid agent part is discharged through the overflow pipe end 30 of the overflow pipe 24. The discharged liquid agent portion is generated from the area of the floor portion 22 of the collection tray 20. Since the liquid 11 guided from the area of the floor portion 22 of the collection tray 20 does not contain floating contaminant particles, it can be reused. Therefore, the liquid agent 11 is collected by the overflow portion 33 and returned to the storage container 12. From there, it can be supplied again to the spraying devices 8 and 9 by the pump 10.

  By the way, the ratio of the liquid agent part that flows out beyond the upper edge 25 of the collection dish 20 and the liquid agent part that flows out through the overflow pipe end 30 of the overflow pipe 24 is adjusted by the setting of the overflow pipe end 30. Can do.

  For example, when the overflow pipe end 30 is positioned at a position that is somewhat higher than the upper edge 25 of the collection tray 20 in the vertical direction (for example, a position that is about 1 mm or 2 mm higher), most of the liquid 11 is collected in the collection tray 20. Spills over the upper edge 25. On the other hand, when the overflow pipe end 30 is positioned at a position lower than the upper edge 25 of the collection tray 20, that is, at a low height, most of the liquid agent 11 flows out beyond the overflow pipe end 30.

  This setting can be performed according to the fiber material 2. In the case of a fiber material 2 that is heavily contaminated, or in which the contaminant particles are easily separated, the end of the overflow pipe is less than in the case of the fiber material 2 that is less contaminated, or the fiber material 2 that hardly separates the contaminant particles. The unit 30 is set to be high.

  The amount of the liquid 11 that has been reduced to the fiber material 2 can be accurately determined by the two volume flow sensors 19 and 29. In order to determine the amount of the liquid agent 11, it is only necessary to determine the difference between the volume flow rate of the liquid agent 11 flowing through the water pipe 18 and the volume flow rate of the liquid agent 11 flowing through the outflow pipe 28.

  Further, at least a part of the liquid agent 11 flowing out through the outflow pipe 28 can be processed so that it can be reused. In order to perform this process, the outflow line 28 is coupled to a contaminant removal device 35 having a filter device, for example. In the case of this configuration, the pollutant removal device 35 is coupled to the storage container 12 via a conduit 36. Further, a volume flow sensor 37 is disposed inside or on the surface of the conduit 36. And in order to obtain | require the injection | throwing-in amount to the fiber material 2 of the liquid agent 11, although it is necessary to add an above-described difference to the volume flow rate calculated | required by the volume flow sensor 37, this calculation can be performed easily.

  The illustrated liquid agent circulation device, which includes a storage container 12, a pump 10, an injection spray device 8, 9 (or another liquid agent supply device), a collection dish 20, and an overflow pipe 24, is attached with floating contaminant particles. Naturally, it can also be used in another problem in which the solution 11 or some other solution to be circulated. In any case, the liquid 11 is taken out from the lower region of the collection dish 20 where the liquid is not contaminated. And this taken-out liquid agent part can be returned to the storage container 12 again.

  In the configuration described above, only the floating contaminant particles are removed, so that another liquid component can remain in the liquid. If the fiber material 2 is formed, for example, by strands containing lignin or pigment, when the contaminants are washed away from the fiber material 2 by the solution 11, these lignin or pigment are supplied again.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope shown in the claims. That is, embodiments obtained by combining technical means appropriately modified within the scope of the claims are also included in the technical scope of the present invention.
