Description
Technical field
The present invention relates to the method and apparatus of the synthetic threads in a kind of continuous processing heat exchange chamber, yarn wherein to be processed directly contacts with heat exchange medium, heat exchange chamber has yarn inlet and yarn outlet, the sealing device that is filled with sealing medium is set respectively on yarn inlet and yarn outlet, and the sealing device has the sealing medium input channel near output yarn or input yarn.
Background technology
EP0624208B1 discloses a kind of like this device.This heat exchanger is made heater earlier and is used, and then uses as cooling device.Under different situations, once Jia Re fluid directly contacts with yarn with the fluid of once cooling.For this reason, its fluid is arranged in the heat exchange chamber that its fluid flows through.This heat exchange chamber has aperture substantially in a tubular form and at its two ends, and its yarn passes wherein and drawn after passing this heat exchange chamber again.
The shortcoming of this cooling device or heater is, can stop to add hot fluid or cooling fluid is discharged from yarn inlet or yarn outlet.In order to address this problem, prior art (DE-OS2430741) discloses different sealing devices, as cartridge type sealing, lip seal and labyrinth sealing, because simple in structure being widely used.In addition, for example open a kind of like this labyrinth sealing of EP760874 (being WO95/32325).This labyrinth sealing comprises a plurality of throttlings chamber, and they communicate with each other by small through hole, and its size just in time can be passed yarn.In order to play sealing function, at each outer end input compressed air of labyrinth sealed.Its compressed air also can be replaced by steam or superheated steam.
Though the sealing that has such particularly gaseous medium highly significant, sealing medium also will enter heat exchange chamber and contact with the heat exchange medium that is made of liquid such as water herein, can produce foam.If use the sealing medium of gaseous state and liquid heat exchange medium to occur this problem especially easily.
This heat exchanger for horizontal type structure is unimportant, and its reason is that foam generally all forms on liquid level, and, because the parallel distribution with yarn of effect of liquid, therefore, the heat exchange that directly contacts formation by yarn and heat exchange medium is constantly successfully carried out.But heat exchanger that needs as a rule or cooler are not to be horizontally disposed with, but vertically are provided with or arbitrarily are obliquely installed.Like this, can form foam regions in the upper end of heat exchanger, this can cause heat exchange effect to reduce greatly and needs obviously increase the processing distance.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of sealing device of heat exchanger yarn port is provided, and can not influence the efficient of heat exchanger.
The objective of the invention is method by claim 1 and claim 11,15 and 17 device is realized.
Design of the present invention is, because sealing medium such as air and all gaseous mediums can produce very strong insulating effect, if sealing medium and the yarn that passes heat exchange chamber can be separated, just can obviously improve the efficient of heat exchanger.This does not depend on that fully sealing medium does not enter heat exchange chamber and mixing, but sealing medium and yarn will be separated, and makes heat exchange medium to yarn generation effect, thus, obtains stablizing rational heat exchange ratio.
US-PS3783649 has described a kind of fluid seal apparatus, and it attempts to prevent that sealing medium from entering heat exchange chamber and preventing mixes in its chamber with heat exchange medium.In this system, fluid itself is as sealing device and forming the fluid sealing before the material import and export in heat exchange chamber.Fluid, water for example with the communication port of very high velocity flow to heat exchange chamber, wherein, is determined the fluid-encapsulated outlet and the communication port of fabric by the speed of the sealing medium that flows out from annular seal space, its communication port is in outlet or the inlet back or the preceding connection of heat exchange chamber.As long as fluid-encapsulatedly can not remain in a standstill owing to static pressure produces certain, the fluid-encapsulated spill cavity with fabric and air-dry here or discharge that just flows into.As can be seen, for keeping this balance between the pressure release of heat exchange chamber and sealing medium or between its speed, need carry out Pressure control, its expense is bigger; In addition, shared place and the manufacturing thereof of described fluid sealing system needs very big expense.
The present invention and main different being of described prior art: in common sealing device, charge into sealing medium in as labyrinth sealing, and sealing medium itself does not form sealing device.Apparatus structure of the present invention, simple to operate, and the pressure adjusting is difficult for ging wrong.In addition, its heat exchange operation is controllable.
DE-OS2002349 discloses the method and apparatus of sealing adjacent chambers, be contained in wherein that gaseous medium in its chamber is sucked out and in groove or head piece zone to enter same chamber again with respect to the less angle in material road.This known method is difficult for stoping the formation of foam, and this is owing to along with entering of heat exchange medium can produce jet action, suck uncontrollable air and produce foam with liquid mixing by its jet action meeting.
Prevent that by sealing device being charged into sealing medium and before heat exchange chamber, exporting sealing medium it from not entering annular seal space fully and also can not contacting with the yarn that passes heat exchange chamber fully thus.
By being also advantageous in that of yarn mouth heat outputting exchange media, do not need to regulate exactly sealing medium and heat exchange medium.In all cases, its heat exchange medium must be to discharge from heat exchange chamber.In principle, the heat exchange medium/sealing medium of mixing discharges from heat exchange chamber, makes sealing medium separate with yarn in heat exchange chamber.
For simplicity, heat exchange medium is discharged with sealing medium, then heat exchange medium is separated with sealing medium also and can utilize heat exchange medium again.
Make sealing medium be with the other method that the yarn that passes heat exchange chamber separates, though sealing medium enters heat exchange chamber, but prevent that by certain high pressure heat exchange medium from discharging from heat exchange chamber, and the sealing medium that will enter heat exchange chamber separates with yarn, thereby stops the insulating effect to heat exchange medium.
The another method that sealing medium is separated with the yarn that passes heat exchange chamber is, heat exchange medium imports on the yarn of heat exchange chamber inside, strengthening direct contact, and by flowing the sealing medium that passes heat exchange chamber separated with yarn.
By entering and the formation of foam of monitoring sealing medium, can obtain certain froth zone as required, and shortening heat exchange distance thus, thereby can adapt to different operating conditions and change as the speed of service at yarn in simple mode the time.
According to the method that is adopted, its heat exchanger has the output channel of sealing medium, and it is arranged near the yarn mouth of heat exchange chamber.According to its effect, its sealing device comprises the labyrinth sealing with throttling chamber.Feeding between the throttling chamber near yarn outlet or yarn inlet by its input channel, preventing that sealing medium from leaking, and output channel near drawing in the throttling chamber of heat exchange chamber, can output so that sealing medium and heat exchange medium expand.In order to discharge the sealing medium that enters heat exchange chamber the guide plate that passes yarn is set in heat exchange chamber, and makes the sealing medium of importing by separating with yarn.
Contact with the direct of the yarn that passes heat exchange chamber in order to guide heat exchange medium and to improve, in heat exchange chamber, narrowed portion centrally is set with yarn, wherein before narrowed portion and the input channel and the output channel of heat exchange medium are set afterwards, make heat exchange medium by flowing through its narrowed portion in the opposite direction with the side of yarn operation.
The sealing medium of discharging from the throttling chamber that is set directly at before or after the heat exchange chamber enters heat exchange chamber, but has a segment distance apart from the yarn mouth, thus, prevent that sealing medium from entering the yarn port area, the sealing medium that enters heat exchange chamber from output channel separates like this with yarn, promptly avoids influencing its heat exchange.The major advantage of the heat exchanger of this structure is, can also control, change its cooling length thus with the formation of simple mode control foam.
The structure of the heat exchange chamber of all embodiments is special by this way to interrelate with controlled cooling distance valuably, and for example for the heat exchange chamber of vertical setting, the yarn of operation and the horizontal plane of cooling fluid are crossing.

The specific embodiment
By a heat exchanger embodiments of the invention are described, it uses as cooler in the deformation technique of synthetic threads, yarn wherein to be processed with very high speed as passing its cooler with the speed of service more than the per minute 2000m.It requires to have very high cooling effect, for example in a short period of time yarn is cooled to 50 ℃ approximately from 200 ℃ approximately.Use the water that directly contacts with yarn as cooling agent.Utilize air to give sealing device 2 aeratings.Certainly, in corresponding technology be the employed heat exchanger of corresponding purpose, also can use other heat exchange medium or sealant.The heat exchanger of handling synthetic threads by an embodiment being used to of describing also can no problem be used to handle fabric filler rod or film.
Heat exchanger as cooler illustrated in fig. 1 has matrix 6 and cover plate 60.Its heat exchanger is discerptible, promptly makes that by unloading lower cover 60 yarn of operation comes out on the matrix 6, can successfully draw like this and wear its yarn F.According to corresponding target, on the heat exchanger that vertically is provided with, a floss hole 14 is set, so that before opening heat exchange chamber 1, can discharge its cooling medium.
Its heat exchanger comprises the heat exchange chamber 1 with yarn inlet 12 and yarn outlet 11.In order to prevent the leakage of cooling liquid, before yarn inlet 12 and sealing device 2 is set respectively after yarn outlet 11, for simplicity, its sealing device 2 is made of the labyrinth sealing with throttling chamber 23, and yarn F passes its throttling chamber 23 from the top down.Its sealing device 2 adds sealing medium by input channel 21, as air.Its sealing medium is input between the two first throttle chambeies that its yarn F passes when yarn enters heat exchanger, and after output channel 22 enters its heat exchange chamber 1 again from last throttling chamber 23 before the yarn inlet 12.Its cooling medium also can enter its inlet before 12 last throttling chamber 23 or export first throttle chamber 23 after 11, up to it being detained there by its sealing medium.
Its heat exchange chamber 1 has the inlet 15 of cooling medium, and described cooling medium flows through its heat exchange chamber 1.Through enter the mouth 12 and outlet 11 its cooling mediums discharge from its heat exchange chamber 1 and be pooled to inlet 12 before and throttling chamber 23 after the outlet 11, enter disengagement chamber 4 with sealing medium through output channel 22, its disengagement chamber also can hold standby cooling medium.Like this, heat exchange medium can not mix in heat exchange chamber 1 with sealing medium, makes can not produce foam in heat exchange chamber 1.Because cooling medium and sealing medium at first with its inlet 12 or export in the 11 adjacent throttling chambeies 23 and contact with each other, make air and mixing at first of water carry out outside heat exchange chamber 1.In case particularly the initial stage in its operation produces foam in heat exchange chamber 1, they can be discharged through steam vent 17 when valve 18 is opened.When heat exchange chamber 1 was horizontally disposed with, its steam vent 17 was arranged on the cover plate 60 for this reason.When heat exchange chamber 1 vertically is provided with, by the horizontal plane of its outlet and its its cooling agent of valve regulated, to regulate desirable cooling distance.
The circulation of cooling medium is controlled by pressure-regulating device 42 by pump 41.Equally, sealing medium feeds two sealing devices 2 by pressure-regulating device 24 controls and input channel 21.By cooling medium and sealing medium are guided to the throttling chamber 23 that two media pressure is reduced, do not need to regulate accurately the pressure balance of two media.The size of the pressure of its cooling medium should be able to produce desirable circulation, and the sealing medium under the certain pressure effect makes throttling chamber 23 and output channel 22 work.Two media expands and flow back under atmospheric pressure in its collection container 4, and cooling medium and air separation in its collection container are eliminated foam.Simultaneously, the cooling medium of heat exchange chamber 1 through enter the mouth 15 be transfused to again before, its cooling medium here also will be cooled.
Fig. 2 shows the perspective view of its matrix, and it has heat exchange chamber 1 and sealing device 2, and they have the interface that is communicated with input channel 21 and the output channel 22,14 and 17 of Fig. 1.
Fig. 3 shows another embodiment of heat exchanger, and wherein its yarn F moves equally from the top down.Be transfused to sealing device 2 through input channel 21 sealing mediums such as air, here it is a kind of labyrinth sealing and has 4 throttling chambeies 23, the yarn outlet 11 of sealing heat exchange chamber 10 and yarn inlet 12.In this embodiment, the output channel of sealing medium is not set, and for the cooling medium that flows into heat exchange chamber 10 by input channel 15 is provided with an output channel 16, so that cooling medium is flow through from heat exchange chamber 10.Sealing medium, is discharged from the yarn port 11 and 12 of heat exchange chamber 10 to prevent cooling medium through input channel 21 its sealing devices 2 of input by such pressure.Particularly, upwards to the cooling medium pressurization of liquid, can in heat exchange chamber 10, produce undesirable foam at yarn outlet 11 cooling mediums for vertical structure.In addition, the air pressurized that makes progress that plays insulating effect can hinder the heat exchange between yarn F and the cooling medium.For this reason, a V-arrangement guide plate 13 is set directly at the yarn traffic direction and before yarn outlet 11, makes compressed air upwards also avoid yarn F thus to side deflection.Its V-arrangement guide plate 13 has a narrow path that yarn F is passed through on its angle, compressed air can here not rise.Because traffic direction and the compressed-air actuated reverse movement of yarn F also can not be mingled with yarn.Against the traffic direction of yarn F, compressed air is avoided yarn F and is deflected into the side by the effect of guide plate 13.Compressed air that rises and issuable foam are discharged through output channel 16 with cooling medium.The same with the embodiment of Fig. 1, the mixture of handling cooling medium and sealing medium is separation of air and water, cools off and sends back in the loop.Here its sealing medium also can discharge or form the controlled horizontal plane of a cooling medium and form a variable cooling distance thus by exhaust outlet 17.
Fig. 4 shows the another embodiment of theme of the present invention.Two sealing devices 2 charge into the sealing medium that is preferably air through input channel 21.Cooling medium is discharged by output channel 16 through input channel 15 inputs and from heat exchange chamber 10 again.At the yarn inlet 12 same compressed air of bringing yarn into heat exchange chamber 10 and avoiding rising yarn F is produced insulating effect for fear of its cooling medium, from the yarn 12 throttling chambeies 23 that are provided with previously that enter the mouth sealing medium is imported heat exchange chamber 10 through output channel 25 and 25 ', and with yarn inlet 12 away from, make compressed air avoid yarn F and rise to the wall of heat exchange chamber 10 from the side.In addition, also improved cooling effect by such device.
Fig. 5 shows another embodiment of heat exchanger of the present invention.Yarn moves from bottom to top, yet its inverted running also is no problem.As described above the same, its sealing device 2 is provided with the input channel 21 of sealing medium equally and charges into air as sealing medium.It also can be provided with output channel 22 among Fig. 1 or the output channel 25 and 25 ' among Fig. 4.Also can expect and adopt the guide plate 13 in Fig. 3 embodiment.And the special feature of the present embodiment is, its heat exchange chamber 100 is divided into chamber 100 ', 100 by narrowed portion 19 " and 100 .Wherein cooling medium is discharged and pass through output channel 16 through input channel 15 inputs, makes cooling medium flow through its heat exchange chamber 100 in the opposite direction with the side of yarn operation.
As can be seen, its yarn forms air ring also with the twisted cooling medium that imposes on by the twist configuration of operation.Cooling medium is expressed to the fringe region of heat exchange chamber 100 under action of centrifugal force, and the unlifting pressure cooling medium is in the middle part with yarn F, and its yarn contacts with rising pressurized seal medium.In order to form this influence, narrowed portion 19 is set thus, make yarn F centrally remain on the middle part of heat exchange chamber 100.Its narrowed portion 19 also plays and strengthens the effect that this position cooling medium flows, thereby makes the air that rises separate with yarn F by the cooling medium of forced flow.From this embodiment, also can find out, can obviously improve cooling effect.
By sealing medium is separated with the yarn F that passes heat exchange chamber, obviously improved cooling effect.Its effect improves 40%.In addition, the water and air of cooler needs reduces.Particularly in non-horizontal structure, shortened cooling length by high cooling effect.The obvious raising of heat exchange chamber efficient is not based on there being air in heat exchange chamber, water is not with pressure at least flows.Yarn no longer contacts with band means of press seals medium, makes directly to contact with heat exchange medium all the time when yarn passes heat exchange chamber.Simultaneously, seal its heat exchange chamber, prevent the leakage of cooling medium by the sealing medium that charges into.The common ground of all described embodiments is that when yarn passed heat exchange chamber, sealing medium separated with yarn F, and promptly or sealing medium does not enter its chamber, or its sealing medium separates with yarn in this chamber.Can adopt each above-mentioned embodiment, also can carry out different combinations in useful mode the one or more of above-mentioned embodiment.
In addition, in possible range of the present invention, by being regulated, the pressure of sealing medium and/or cooling medium forms a foam formation chamber of determining, to dwindle useful especially cooling distance.Like this, make the cooling and the speed of service that slows down adapt in simple mode.To this, can adopt Fig. 5 compartment, only work by cooling medium in two chambeies wherein, and the 3rd chamber holds foam or the air that does not in fact play cooling effect.For this reason, in this case, can also give chamber 100 " and chamber 100 ' configuration cooling medium input channel 15 " and 15 ', make cooling medium flow through one, two or all three chambeies selectively.
From described embodiment as can be known, sealing medium applies high pressure through input channel 21 to sealing device 2.And further be characterised in that, form negative pressure in output channel 22, make sealing device 2 be in negative pressure state.The cooling medium that comes out from yarn mouth 11 and 12 is soon away from outlet and get back to the cooling circuit.Can remove input channel 21, strengthen the swabbing action in the throttling chamber 23 like this, prevent to leak.Particularly leave yarn outlet 11 places of the heat exchange chamber 1 that soaks into cooling medium at yarn, with cooling medium, air sealing device is pressurizeed, be all can produce same effect by high pressure or negative pressure, the very fast drying of the yarn that promptly from cooling medium, comes out.
