Description
Technical Field
The present invention relates to a cooling device in textile machinery, and more particularly, to a cooling device for cooling synthetic fibers using a cooling liquid.
Background
WO0138620A1 discloses a method for cooling a twisted yarn. After the yarn is heated by the heating device, the yarn is cooled by the water cooling device located at the downstream side of the heating device, and then the yarn enters the twisting device. The method utilizes a metering pump to convey the cooling liquid in a cooling liquid tank to a water cooling device, and uses an exhaust device to exhaust the steam after cooling yarns to a condensing device, and the condensed cooling liquid is conveyed to the cooling liquid tank.
Regarding how to treat the cooling liquid and the steam, it is clearly disclosed in the patent claims and the description of WO0138620A1 that the steam generated after the cooling liquid is heated by the hot yarn is led along the exhaust duct into the condensing device under the effect of the exhaust device and the remaining part of the cooling liquid is led along with the yarn into the twisting device. Therefore, the remaining amount of the cooling liquid needs to be controlled as much as possible within a certain range to avoid excessive accumulation in the water cooling device and excessive adhesion of the yarn. For this reason, this patent document itself proposes to dose the coolant by means of a metering pump driven by a drive. In this solution, however, the supply of the cooling liquid needs to be monitored additionally, for a long time, and feedback is provided to the metering pump so that the metering pump can adjust the delivered amount of the cooling liquid accordingly.
Disclosure of Invention
Accordingly, in order to improve the shortcomings of the prior art on the basis of the prior art, the present invention provides a cooling device for a textile machine for cooling synthetic fibers using a cooling liquid. The technical scheme adopted by the invention and the technical effects brought by the technical scheme are fully described below.
The first aspect of the present invention is a cooling device for cooling synthetic fibers by a coolant in a textile machine, comprising a plurality of cooling elements for cooling synthetic fibers by a coolant, a coolant supply device for distributing the coolant to the plurality of cooling elements, and a coolant collection device for collecting the coolant remaining after cooling the synthetic fibers, wherein the coolant collection device has at least one intermediate pipe which communicates with the plurality of cooling elements to collect the remaining coolant, and the intermediate pipe communicates with a suction pipe of a suction device.
During the cooling of the heated yarn by the cooling liquid, a part of the cooling liquid is evaporated into steam which is pumped away from the cooling element through the suction pipe of the suction device. The remainder of the cooling liquid flows from the cooling element to the at least one intermediate conduit. The cooling liquid and the cooling liquid vapor are separated and collected separately. The flow of the remaining cooling liquid is more positive under the suction air flow of the suction device, and the cooling liquid and impurities in the cooling liquid can be prevented from blocking the intermediate pipe and the connecting pipe between the intermediate pipe and the cooling element.
According to a second technical scheme adopted by the invention, a connecting end of the middle pipeline connected with the suction pipeline and an outflow end of the middle pipeline are positioned at opposite ends of the middle pipeline.
The intermediate conduit allows the collected coolant to dwell briefly and flow out of the outflow end of the intermediate conduit to downstream devices for further collection. The design of the connection end and the outflow end being arranged at opposite ends of the intermediate pipe makes the intermediate pipe have more reasonable space for connecting the intermediate pipe with the pipes between the plurality of cooling elements, and does not cause problems when the connection end and the outflow end are arranged at the same end, i.e. the connection end is blocked first because the outflow speed of the cooling liquid from the outflow end is slower, the liquid level of the cooling liquid in the cooling elements rises.
According to a third technical scheme adopted by the invention, the connecting end of the suction pipeline is higher than the outflow end of the middle pipeline, and the middle pipeline is arranged at an inclined angle of 1-5 degrees relative to the horizontal plane.
This inclined arrangement allows the coolant to maintain a tendency to flow toward the outflow end without significantly increasing the vertical space of the intermediate pipe.
According to a fourth technical scheme adopted by the invention, the cooling liquid collecting device is provided with a total collecting pipeline communicated with outflow ends of a plurality of intermediate pipelines, and the total collecting pipeline is communicated with a cooling liquid tank of the cooling liquid supplying device.
The cooling liquid is fed from the cooling liquid tank to the cooling element, and the cooling liquid tank remaining after cooling the yarn flows back to the cooling liquid tank, so that the cooling liquid is recycled.
The fifth technical solution adopted by the present invention is that the cooling liquid collecting device has a total collecting pipe communicating with the outflow ends of the plurality of intermediate pipes, and a cooling liquid collecting tank communicating with the total collecting pipe.
Unlike the fourth solution described above, the total collecting pipe conveys the remaining coolant to a coolant collecting tank that is independent of the coolant tank. This makes it possible to further process the collected cooling liquid afterwards. For example, when the oil content in the cooling liquid is low, the oil amount is increased thereto, or when the impurity content in the cooling liquid is high, further filtration is performed.
According to a sixth aspect of the present invention, the coolant supply device has the coolant tank, a reservoir connected to the coolant tank by a reservoir pump, a total distribution pipe connected to the reservoir at one end, and a supply pump connected to the total distribution pipe and the plurality of cooling elements by branch pipes, respectively.
The liquid storage tank pump conveys the cooling liquid in the cooling liquid tank to the liquid storage tank, and the cooling liquid is temporarily stored in the liquid storage tank. The total distribution pipe supplies the cooling liquid to the respective cooling elements through the branch pipes and a supply pump disposed on each of the branch pipes, respectively.
According to a seventh technical scheme of the invention, a delivery pump for delivering the cooling liquid in the cooling liquid collecting box to the cooling liquid box is arranged on a connecting pipeline of the cooling liquid box and the cooling liquid collecting box. If necessary, the coolant in the coolant collection tank after further processing is fed to the coolant tank as a coolant supply source, forming a circulation of coolant from supply to collection to supply.
Based on the concept of the aforementioned second technical means, the structure of the intermediate duct is designed as an eighth technical means of the present invention, namely, between the connection end of the suction duct and the outflow end of the intermediate duct, the plurality of cooling elements being respectively communicated with the intermediate duct through separate collecting ducts along the length direction of the intermediate duct.
The cooling device is particularly suitable for false twisting deformation machines in the textile machinery field, and a ninth technical aspect of the invention is therefore a false twisting deformation machine with a plurality of treatment stations, wherein the treatment stations have a heating device comprising a plurality of heating devices and a cooling device comprising a plurality of cooling elements, and the cooling device is constructed according to any one of the first to eighth technical aspects.
According to a tenth aspect of the present invention, the plurality of cooling elements are divided into a plurality of cooling element groups, each cooling element group is connected to one of the plurality of intermediate pipes, and the plurality of intermediate pipes are connected to the total collecting pipe to achieve the regional collection of the cooling liquid.

Detailed Description
In textile machines that require cooling of the yarn, common cooling modes are classified into passive cooling, which uses the contact of the yarn and the metal to transfer heat to the metal for heat dissipation, and forced cooling, which mainly uses cooling air or cooling liquid for forced cooling of the yarn. The passive cooling method requires a longer cooling length and the forced cooling method requires a shorter cooling length, but requires an additional device for supplying the cooling medium. The principle of cooling the yarn with a cooling liquid is described in WO0138620A1 or EP3312321, in particular EP3312321 describes in detail the specific structure of the cooling element.
The invention provides an improvement on a cooling device for cooling yarns by using cooling liquid in a forced cooling mode. The cooling liquid can be formed by mixing common distilled water and spinning oil, or other chemical components can be added according to different yarn types. The cooling device of the present invention mainly comprises a plurality of cooling elements for cooling synthetic fibers by using a cooling liquid, a cooling liquid supply device for distributing the cooling liquid to the plurality of cooling elements, and a cooling liquid collection device for collecting the cooling liquid remained after cooling the synthetic fibers. Fig. 1 schematically shows a schematic structure of a cooling apparatus of the present invention. In this embodiment, the number of the plurality of cooling elements is three, and the cooling principles and the internal structures thereof are respectively 11.1, 11.2 and 11.3, and reference is made to the prior art with publication number EP 3312321. The cooling disclosed is in such a way that the cooling liquid flows under the transport of the pump over the open cavity surfaces inside the vertically arranged cooling element, the heated yarn being cooled in contact with the cooling liquid when passing through said cavity. And part of the cooling liquid is evaporated into steam under the action of the high-temperature yarn, and the other part of the cooling liquid flows out of the lower end of the cooling element along the vertical direction.
Fig. 1 shows in particular a schematic view of the cooling device with an intermediate duct cooperating with a set of cooling elements for collecting the cooling fluid. In the embodiment shown in fig. 1, the coolant supply device mainly comprises a coolant tank 1, a reservoir pump 3, a reservoir 4, a reservoir connection pipe 4.1, a main distribution pipe 5, a branch pipe 6, a supply pump 7 and branch pipes 8.1, 8.2, 8.3, the connection of which will be described in detail below; the above-mentioned coolant collecting device mainly includes branch collecting pipes 12.1-12.3, an intermediate pipe 10, a return pipe 13, a main collecting pipe 14, and a coolant collecting tank 16, and their connection relationships will be described in detail below. The cooling liquid tank 1 contains a certain amount of cooling liquid, and known distilled water and spin finish can be mixed in advance to form a desired cooling liquid. The cooling liquid tank 1 is communicated with the liquid storage tank 4 through a liquid storage tank connecting pipeline 4.1. The liquid storage tank connecting pipeline 4.1 is provided with a first filter element 2 and a liquid storage tank pump 3 which are sequentially separated from each other, and the first filter element 2 is positioned between the cooling liquid tank 1 and the liquid storage tank pump 3. The cooling liquid passes through the first filter element 2 to filter impurities in the cooling liquid before being delivered to the liquid reservoir 4 by the liquid reservoir pump 3. The liquid storage tank 4 is connected with one end of the total distribution pipeline 5. The main distribution line 5 communicates via a branch line 6 with a feed pump 7, which feed pump 7 is connected via branch lines 8.1, 8.2, 8.3 to the cooling elements 11.1, 11.2, 11.3, respectively. The coolant is fed from the reservoir 4 to the cooling elements 11.1, 11.2, 11.3 by the feed pump 7, wherein the feed pump 7 is preferably a gear pump and the branch pipes 8.1, 8.2, 8.3 are preferably flexible pipes which facilitate bending deformations. The supply quantity of the supply pump 7 can be controlled in such a way that the cooling fluid enters the cooling elements 11.1, 11.2, 11.3 in the form of drops. The yarn advancing at high speed is cooled after contact with the cooling liquid, a part of the heated cooling liquid evaporates into gas, and flows out of the open cooling elements 11.1, 11.2, 11.3, and the other part of the steam enters the branch collecting pipes 12.1, 12.2, 12.3 respectively communicated with the lower ends of the plurality of cooling elements 11.1, 11.2, 11.3 along with the yarn advancing at high speed. The remaining cooling liquid flows in the vertical direction into the sub-collecting pipes 12.1, 12.2, 12.3 arranged in the vertical direction. The lower ends of the branch collecting pipes 12.1, 12.2 and 12.3 are communicated with the middle pipe 10, and the connecting positions of the branch collecting pipes are distributed along the length direction of the middle pipe 10.
The remainder of the cooling liquid and the steam flow through the sub-collection pipes 12.1, 12.2, 12.3 and then enter the intermediate pipe 10 which communicates with the suction device 19. The suction device 19 has a suction fan 9 and a suction duct 18, the interior of the suction duct 18 generating suction in the direction indicated by the dashed arrow under the action of the suction fan 9. One end of the middle pipe 10 is a connection end 20 which is communicated with the suction pipe 18 of the suction device 19, namely the right side end of the middle pipe 10 in fig. 1. The other end of the intermediate pipe 10 is an outflow end 21 for remaining cooling liquid to continue flowing in the direction of the solid arrow, i.e., the left end of the intermediate pipe 10 in fig. 1. The connection end 20 of the intermediate pipe 10 connected to the suction pipe 18 and the outflow end 21 of the intermediate pipe 10 are located at opposite ends of the intermediate pipe 10, and the intermediate pipe 10 is inclined such that the connection end 20 is higher than the outflow end 21. Preferably, the intermediate pipe 10 has an inclination angle with respect to the horizontal in the range of 1 ° -5 °.
When the suction device 19 performs suction operation, the steam inside the intermediate pipe 10 and the branch collecting pipes 12.1, 12.2, 12.3 is sucked and discharged, and the suction operation can effectively prevent impurities in the cooling liquid from blocking the relatively thin branch collecting pipes 12.1, 12.2, 12.3, so that the flow of the cooling liquid along the solid arrow direction is quickened. In addition, when the coolant in the intermediate pipe 10 flows out from the outflow end slowly, the coolant will accumulate in the intermediate pipe 10 and will not block the connection end 20 at the farther end in a short time.
The remaining cooling liquid flowing out of the outflow end 21 of the intermediate pipe 10 flows through the return pipe 13 into the main collecting pipe 14. The total collecting pipe 14 is connected to a coolant collecting tank 16 for intensively storing the remaining coolant. The total collecting pipe 14 is disposed obliquely so that a portion distant from the coolant collecting tank 16 as a whole is slightly higher than a portion close to the coolant collecting tank 16. In order to be filtered before the remaining impurities of the cooling liquid enter the cooling liquid collecting tank 16, a second filter element 15 is provided on the total collecting pipe 14 close to the cooling liquid collecting tank 16.
In order to form a closed loop, the coolant collection tank 16 communicates with the coolant tank 1. A transfer pump 17 is used to transfer the coolant collected in the coolant collection tank 16 into the coolant tank 1 to reuse the coolant.
Fig. 2 is a schematic view of a false twist texturing machine for cooling yarn using the cooling apparatus described above. The following description follows the order in which the yarns are processed. The yarn 28.1-28.6 is drawn from the thread position 22.1-22.6 by the active transport action of the first transport device 27.1-27.6. In this embodiment, the first conveying means 27.1 to 27.6 are designed as a nip structure, and the yarn is conveyed between two opposing rollers.

The false twisting devices 24.1-24.6 are positioned at the downstream side of the cooling elements 11.1.1, 11.2.1, 11.3.1, 11.1.2, 11.2.2, 11.3.2 for false twisting the yarn. The yarns 28.1-28.6 acquire crimp characteristics under the combined action of the heat treatment devices 23.1-23.6, the cooling elements 11.1.1, 11.2.1, 11.3.1, 11.1.2, 11.2.2, 11.3.2 and the false twist treatment devices 24.1-24.6. Subsequently, the yarn enters the respective second conveying means 25.1-25.6, which are of similar construction to the first conveying means 27.1-27.6, and the conveying speed of the second conveying means 25.1-25.6 is faster than the conveying speed of the first conveying means 27.1-27.6, thus providing a stretching effect to the yarn. Finally, the yarns are wound up on the respective winding devices 26.1 to 26.6. The cooling elements 11.1.1, 11.2.1, 11.3.1, 11.1.2, 11.2.2, 11.3.2 are divided into two groups A, B. The cooling elements of group a comprise three cooling elements 11.1.1, 11.2.1, 11.3.1 and the cooling elements of group b comprise three cooling elements 11.1.2, 11.2.2, 11.3.2. The cooling elements of group a are provided with a feed pump 7.1 and the cooling elements of group B are provided with a feed pump 7.2.

The following description is directed to differences from fig. 1 only. The branch lines 6.1, 6.2, which are connected to the main distribution line 5, are connected to the respective distributed feed pumps 7.1, 7.2. The cooling fluid remaining in the cooling elements 11.1.1, 11.2.1, 11.3.1 flows via the respectively assigned sub-collecting lines 12.1.1, 12.2.1, 12.3.1 to the intermediate line 10.1 and, after the outflow, via the return line 13.1 to the main collecting line 14. The cooling fluid remaining in the cooling elements 11.1.2, 11.2.2, 11.3.2 flows via the respective associated sub-collecting line 12.1.2, 12.2.2, 12.3.2 to the intermediate line 10.2 and, after the outflow, via the return line 13.2 to the main collecting line 14.
The connection ends 20.1, 20.2 of the intermediate lines 10.1, 10.2 opposite the outflow ends 21.1, 21.2 thereof for connection to the return lines 13.1, 13.2 are connected to the suction lines 18.1, 18.2 of the suction device 19, respectively. The suction lines 18.1 and 18.2 communicate with a common suction fan 9. The connecting ends 20.1, 20.2 of the intermediate pipes 18.1, 18.2 are each higher than the outflow ends 21.1, 21.2.
