BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a landing treatment apparatus, and more particularly, to a landing treatment apparatus for wet treatment of a landing material such as dyeing.

Conventional package dyeing apparatus includes a primary bleaching tank, which is a vertically oriented cylindrical vessel and contains a yarn to which dyeing is applied during the dyeing treatment. Yarn packages are typically loaded onto a suitable carrier which carries the yarn into the bleach bath. When the carrier is inside the bleach bath, the carrier (s) is connected to a circulation system of the dyeing apparatus that circulates the dye to ensure that the dye penetrates properly into the yarn package.

The height of the dyeing unit, along with the height of the main bleach, is related to the capacity of the dyeing unit. Thus, higher devices provide more capacity. Moreover, the required working height is typically twice the dyeing height, in order to provide the height required for loading and unloading by the package carrier. It will be appreciated that in factories with relatively low ceiling heights, it is inappropriate to use higher capacity devices. Thus, such a plant would require the purchase / use of several smaller capacity devices, which would increase operating costs compared to using a single larger capacity device.

Thus, vertical package dyeing devices are not suitable for use in some areas. Thus, a problem associated with vertical dyeing devices relates to methods of using larger capacity devices in limited space. A possible solution may be to provide a package dyeing device with the main bleach bath arranged horizontally. Such an arrangement effectively reduces the working height while substantially maintaining the desired larger capacity. However, in the horizontal arrangement, it was confirmed that the dye solution ratio of the horizontal package dyeing apparatus is higher than that of the existing vertical package dyeing apparatus. In addition, the pressure head distribution inside the package carrier loaded into the horizontal bleach bath is non-uniform due to the lateral flow entry configuration.

In order to reduce the dye liquid ratio, it is known to introduce a hollow container inside the main bleach bath. However, in the side flow entry configuration, the flow pattern through the carrier provides a flow directed into a plurality of straight passages before being dispensed into the yarn package, resulting in a non-uniform pressure distribution. As a result, a uniform distribution of dye occurs, so that the package color of the entrance side is lighter than that of the package far from the entrance side.

Thus, a problem associated with horizontal packages is how to modify the configuration to optimize the dye solution ratio and to improve the distribution of the dye in the skin or yarn to be treated.

Accordingly, a first aspect of the invention provides a bleaching tank arranged horizontally, structural means receivable within the bleaching tank, and fluid flow penetrating means for allowing fluid to flow into the bleaching material to be transported. Provided is a dispensing treatment apparatus comprising a carrier having a fluid flow reversing device connectable to both the bleach bath and the carrier to form a fluid flow of two modes through the bleach bath, the carrier and the landing material in use.

The fluid flow reversing device is preferably of the type disclosed in British Patent Application No. GB-A-2 384 287, the contents of which are incorporated herein by reference. Preferably, the fluid flow reversing device comprises a first conduit having a first arm and a second arm, and a second conduit disposed concentrically around the entire circumference of the first arm of the first conduit, the first conduit comprising: a first conduit; The arm intersects the second arm such that the interior is in fluid flow communication with the interior of the second arm, both the first arm and the second arm have openings at their respective ends, and the first end of the second conduit has an impeller ( impeller, the second end of the second conduit is closed, the first end of the first arm in the first conduit stops short of the closed second end of the second conduit, The second arm is arranged to extend through both sides of the second conduit, the valve positioned at the intersection of the first arm and the second arm of the first conduit for use in the flow of fluid through the second arm of the first conduit. Configured to control the direction.

The fluid flow reversal device facilitates inside-out and out-inside flow of dye liquor through the padding material. Thus, the combination of horizontal bleach bath, carrier and fluid flow reversing device improves fluid distribution through the landing material over prior art configurations.

In a preferred form of the invention, the bleach bath is cylindrical and may have a circular cross section. The bleach bath is a hollow structure and may have a cross-sectional shape of circular or any other suitable form.

Horizontal bleach baths may be suitable for loading one or more carriers therein. It is appropriate that more than one carrier be connected in series. One end of the carrier is operable to be connected with a reducer connectable to the fluid flow reversing device, and the other end of the carrier is connectable to another carrier. Alternatively, the other end may be blocked by the blocking member such that the fluid flow is controlled by the carrier. Preferably, the fluid flow reversing device is disposed at one end of the bleach bath. The fluid flow reversing device may connect the bleach bath to the circulation pump.

The inner space of the bleach bath may comprise a partition member for dividing this inner space into a dummy volume and a loading volume. The loading volume can be about the same shape and size as the carrier housed therein. The loading volume is the space in the main bleach tank that can be filled by the yarn package, and the dummy volume is the space in the bleach tank that cannot be filled by the yarn package due to the cross-sectional shape of the bleach bath.

A second aspect of the invention provides a base having a hollow structure formed by an upper passageway and a lower passageway, a plurality of perforated tubular members standing upright from the base and arranged in a staggered manner and a plurality of perforations installed upright from the base. Provided is a carrier for a land treatment apparatus including a column.

The distribution of staggered perforated tubes improves the spatial arrangement of the yarn package. The unperforated column may occupy an area of the carrier that is not occupied by the lander / yarn package. The construction of the perforated tube and the unperforated column further reduces the volume of treatment liquid used during wet processing such as dyeing. Moreover, the construction of the perforated tubes can provide improved flow and uniform pressure distribution inside the carrier to achieve a more uniform distribution of the dye.

Now, with reference to the accompanying schematic drawings, embodiments of the invention are given by way of example only.

Referring to FIG. 1, the surface treatment apparatus M / C includes a cylindrical main bleach tank 2 arranged horizontally. At one end of the bleach tank 2 there is a door 3 for transporting the landing material loaded on the carrier 1 and allowing access to the landing material. The other end of the bleach tank 2 is in the shape of a raised spherical dish, to which the fluid flow reversing device 4 and the pump 5 are connected. In the apparatus illustrated in FIG. 1, two carriers 1 are connected in series.

As illustrated in FIG. 2, the carrier 1 comprises a hollow rectangular base 8 provided by two hollow rectangular members 6 ′, 7 ′. The first hollow rectangular member 6 'is smaller than the other member 7', and the first hollow rectangular member 6 'is disposed inside the other member 7' so that the lower passage 6 and the upper passage 7 Form two passages. A plurality of perforated spindles 10 are installed standing up from the base 8. A single perforated spindle 10 is shown in FIG. 2 for clarity and a carrier with a plurality of perforated spindles is shown in FIGS. 1 and 3. In the upper passage 7, a plurality of hollow tubes 11 occupy a space provided between the upper portion of the first hollow rectangular member 6 'and the upper portion of the other hollow rectangular member 7'. The hollow tube 11 vertically interconnects the lower passage 6 and the top plate of the base 8. The number of support tubes 11 corresponds to the number of perforated spindles 10. Each spindle 10 is supported inside the hollow tube 11 with its lower end. The arrangement of the spindle 10 on the base is staggered as seen in the arrangement of the holes 23 in FIG. 2. The base 8 also includes a plurality of openings 23 ′ in the form of circular holes, allowing fluid flow between the upper passage 7 and the base 8. The number of holes 23 'typically matches the number of perforated spindles 10 and is also arranged in staggered form.

3 illustrates a carrier 1 on which a plurality of perforated spindles 10 are loaded. In addition, the carrier comprises a plurality of dummy pillars 14 arranged on the base 8 in areas not occupied by the perforated pillars 10 and the yarn package. The dummy pillars 14 are vertically aligned. The space occupied by the dummy pillar 14 has the effect of reducing the volume of the treatment liquid required to fill the bleach tank 2.

A hollow connector 13 ′ is connected to one end of the carrier, connecting the carrier 1 and the fluid flow reversing device 4 (FIG. 1). One end of the hollow connector 13 ′ has a rectangular shape corresponding to the cross-sectional shape of the carrier 1 base 8, and the other end of the hollow connector 13 ′ has a shape of a connection to the fluid reversing device 4. The cross section is round to match. At the other end of the carrier 1, the passages 6, 7 can be closed by an end plate 12 as shown in FIG. 3 or connected in series with another carrier 1 as shown in FIG. 1. . The last carrier 1 connected in series is attached to an adjacent carrier 1 at one end thereof, and an end plate 12 is provided at the other end thereof. Such a configuration allows fluid flow during operation to passages 6 and 7 and through passages 6 and 7 through a perforated spindle 10 carrying holes 23 'and a yarn package 9 on the base. Guaranteed to be limited to

The connector 13 'includes an outer connector and an inner connector forming a passage therebetween. The inner connector 15 is in direct fluid communication with the lower passage 6, while the outer canister 13 is in direct fluid communication with the upper passage 7.

Referring to FIG. 4, the main bleaching tank 2 is provided with a plurality of plate-shaped dividing members 16 which are located around the inner space and divide the inner space into individual loading volumes 19 and dummy volumes 21. It is a cylindrical vessel. The loading volume 19 is a space occupied by the carrier 1 loaded during operation, and the dummy volume 21 is a space for efficiently reducing the space not occupied during operation due to the shape of the carrier 1. The other partition member 18 occupies a part of the lower region of the bleach tank 2 to form a limited space without the processing liquid during the operation, thereby reducing the dye liquid ratio.

The dummy volume 21 and the loading volume 19 are in fluid communication by a hole 17 provided near the bottom of the divider.

The air inlet 20 is provided through the bleach tank wall in the region of the dummy volume 21 so that the compressed air is injected into the dummy volume 21. An air outlet 22 is provided in the bleach tank wall in the loading volume 19 region to release any excess air in the loading volume.

The wet treatment procedure, such as dyeing, using the above described land treatment apparatus (M / C) is as follows.

The yarn package 9 is placed on the perforated spindles carried on the carrier 1 (or each carrier). When the yarn package 9 is ready to be dyed, it is loaded into the bleach tank 2 and then the bleach bath is closed. The transfer of carrier (s) into the bleach bath can be provided by a friction reducing guide, such as a roller track (not shown).

After loading, the bleach bath 2 is filled with the treatment liquid to a predetermined level so that the yarn package 22 is partially submerged. Compressed air is then bleached through the air inlet 22 so that compressed air occupies the dummy volume 21 and pushes any processing liquid, such as dye, from the dummy volume 22 to the loading volume 19. (2) Push it into. As a result, the level of the processing liquid inside the loading volume 19 increases, so that the yarn package is completely submerged in the processing liquid. If the loading volume 19 is occupied by any excess air, the excess air is vented through the vent valve (not shown) and discharged through the air outlet 22.

The flow of treatment liquid such as dye is generated by the pump 5 and the fluid flow reversing device 4. The structure and form of the fluid flow reversing device may be as described in GB-A-2 348 287, the contents of which are incorporated herein by reference.

In the first mode of operation, the pump 5 and the fluid flow reversing device 4 enter a lower passage 6 of the carrier 1 base 8 with a treatment liquid, such as a dye, directed towards the inner connector 15. Is operated to generate an inside-out flow. The processing liquid then flows from the lower passage 6 into the support tube 11 to penetrate into the yarn package 9 from the inner side and flows to the perforated spindle 10. Excess treatment liquid is returned from the yarn package 9 through the loading volume of the bleach bath and through the holes 23 'to the upper passage 7 of the carrier. The returned fluid then passes from the upper passage 7 through the outer connector 13 and back to the fluid flow reversing device.

In the second mode of operation, the pump 5 and the fluid flow reversing device 4 go out into the upper passage 7 of the carrier 1 after a treatment liquid, such as a dye, is directed towards the outer connector 13. Operate to generate an inside flow. Next, the processing liquid flows from the upper passage 7 through the holes 23 'to the loading volume of the bleach tank 2 first to penetrate the yarn package 9 before entering the perforated spindle 10. The treatment liquid then passes through the lower passage 6 via the support tube 11 downward from the inside of the perforated spindle 10. The returned fluid then passes from the lower passage 6 through the inner connector 15 and back to the fluid flow reversing device.

The skin treatment apparatus according to the present invention has a lower dye solution ratio than the conventional horizontal package dyeing apparatus, and also uniformly distributes the dye to make the color of the dye uniform.
