Blade cooler and fiber filament preparation system

Abstract

The present invention discloses a blade cooler and a fiber filament preparation system. The preparation system includes a blade cooler, which includes a base, solid blades, an air supply mechanism, and an air outlet component. A cooling medium is introduced into a first channel of the base to cool all the solid blades. The coolant does not flow into the solid blades, and the solid blades do not experience water seepage. The air supply mechanism introduces gas into a second channel. This gas flows along the surface of the solid blades, adjusting the temperature of the solid blades to make the temperature of the solid blades uniform, thereby making the ambient temperature in the cooling area uniform. The air blown out from the air outlet can blow away volatiles at the roots of the glass fiber filaments. The volatiles rarely condense on the blades, thereby avoiding corrosion of the solid blades by the volatiles, protecting the solid blades, and thus extending the service life of the blade cooler.

Description

Technical Field

[0001] The present invention belongs to the technical field of cooling, and in particular relates to a cooling device and a fiber filament preparation system. Background Art

[0002] During the preparation of glass fiber yarns, a glass fiber solution is placed in a furnace body. A funnel-shaped drawing plate is provided at the bottom opening of the furnace body. Several wire outlet holes are provided on the plate. The glass fiber solution in the furnace body is formed into individual glass fiber yarns through the wire outlet holes of the plate. The root parts of the glass fiber yarns need to be cooled by a cooling device to cool and solidify the glass fiber yarn roots, thereby facilitating the drawing of the heads of the cooled fiber yarns to form glass fiber yarns of the required diameter.

[0003] In the prior art, a blade cooler is generally used to cool glass fiber filaments. The blade cooler includes a base and a plurality of cooling blades installed on one side surface of the base and spaced apart. A U-shaped hollow channel is provided in the cooling blade. An inlet channel and an outlet channel are provided in the base. The coolant enters the hollow channel of the blade through the inlet channel and flows in the blade. Then, the coolant flows to the outlet channel, thereby reducing the temperature of the blade and cooling the glass fiber filaments between two adjacent blades.

[0004] The blade cooler of this structure can cool the blade temperature by allowing the coolant to flow throughout the blade, thus meeting the requirements of the root forming process. However, the U-shaped hollow channel of the blade with this structure is complex to process and has high preparation costs. Moreover, as the use time increases, the hollow channel is prone to cracks, and the coolant leaks in the gaps, resulting in a short service life of the cooler. The cooler needs to be replaced regularly after each period of use. At the same time, the glass fiber volatiles condense on the surface of the blade after being cooled and remain on the blade. The glass volatiles themselves have corrosive components, which corrode the blade and shorten the blade's service life. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is that the blades of the existing blade cooler are prone to internal corrosion, cracks are easily formed on the blades, causing leakage, and glass volatiles corrode the blades, ultimately resulting in a short service life and low production efficiency of the blade cooler.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0047] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0048] Example 1

[0049] This embodiment provides a blade cooler, such as Figures 1 to 9 As shown, it includes a base 1, at least two solid blades 3, an air outlet component 4, an air supply mechanism 2 and a liquid supply mechanism 5.

[0050] Among them, Figure 9 As shown, the base 1 is provided with a first channel 11 and a second channel 12 which are independent of each other; the first channel 11 is for liquid circulation, and the second channel 12 is for gas circulation; the first end of any solid blade 3 is fixed on the base 1, and the second end extends outward as a free end; all solid blades 3 are arranged side by side and spaced apart, and a cooling area is formed between two adjacent solid blades 3; the air supply mechanism 2 is connected to the second channel 12; one end of the air outlet component 4 is provided on the base 1 and connected to the second channel 12, and the other end is provided with an air outlet 41; at least one air outlet component 4 parallel to it is distributed outside at least one side wall of each solid blade 3, and the second end extends outward from the air outlet 41 so that the air outlet 41 blows air to the side wall of the corresponding solid blade 3.

[0051] The blade cooler of this structure introduces a cooling medium into the first channel 11 of the base 1 to cool all the solid blades 3. The coolant will not flow into the solid blades 3, so there will be no water seepage in the solid blades 3 during the cooling process. At the same time, the air supply mechanism 2 introduces gas into the second channel 12. Since the air outlet 41 is located on the inner side of the second end of the solid blade 3, the gas in the second channel 12 blows the side wall of the solid blade 3 through the air outlet 41 of the air outlet component 4. This part of the gas flows along the surface of the solid blade 3, and on the one hand, adjusts the temperature of the solid blade 3, so that the temperature of the solid blade 3 is uniform and controllable, thereby making the ambient temperature in the cooling area uniform, so as to control the The glass fiber roots in the cooling area are evenly cooled, so that the glass fiber diameter is uniform and the fiber quality is significantly improved. On the other hand, part of the gas blown out from the air outlet 41 can also directly cool the glass fiber roots, accelerating the cooling of the glass fiber roots. This part of the wind blows away the volatiles at the glass fiber roots, and the volatiles rarely condense on the blades. Even if a small amount of volatiles condense on the blades, the wind blown out from the air outlet 41 can blow away the condenser staying on the blades, avoiding the corrosion of the solid blades 3 by the volatiles, protecting the solid blades 3, and thus extending the service life of the blade cooler, reducing the frequency of cooler replacement, and improving production efficiency.

[0052] Preferably, if Figure 1 As shown, a liquid inlet pipe 111 is sealed on the inlet of the first channel 11, a liquid outlet pipe 112 is sealed on the outlet of the first channel 11, and the outlet of the liquid supply mechanism 5 is sealedly connected to the liquid inlet pipe 111. As for the cooling medium, the cooling medium is generally selected from water, or other cooling media.

[0053] The liquid supply mechanism 5 includes a liquid storage tank, a pump body, a pressure detector, and a first controller. The two ends of the pump body are connected to the liquid storage tank and the liquid inlet pipe 111, respectively. The pump body draws the solution in the liquid storage tank into the liquid inlet pipe 111, and then transports it to the first channel 11 to cool the base 1. The solid blades 3 are cooled by heat conduction of the base 1. The solid blades 3 then conduct heat conduction with the ambient gas in the cooling area, thereby cooling the glass fiber roots. The pressure detector detects the pressure of the first channel 11. The first controller adjusts the output pressure of the cooling medium transported by the pump body to the required range based on the pressure of the pressure detector, thereby ensuring that the flow rate of the cooling medium transported in the first channel 11 is within the process requirement range and adjusting the cooling intensity of the solid blades 3 to be moderate.

[0054] As for the air supply mechanism 2, it includes a high-pressure gas storage tank, at least one air inlet pipe, a pressure reducing valve, a flow regulating valve and a second controller. Figure 1As shown, there are two air inlet pipes, one end of each of which is sealedly connected to the openings at both ends of the second channel 12, and the other end of each of which is sealedly connected to the outlet of the storage tank. A pressurizing valve and a flow regulating valve are provided at the outlet of the high-pressure gas storage tank. The airflow is first depressurized before passing through the flow regulating valve. A second controller is electrically connected to the flow regulating valve and the temperature detector. Based on the temperature of the solid blades 3 detected by the temperature detector, the second controller controls the pressure reducing valve to first reduce the pressure and then controls the opening of the flow regulating valve to adjust the air supply volume of the high-pressure gas storage tank. This adjusts the cooling temperature and cooling intensity of the solid blades 3, and thus the cooling intensity of the glass fiber filaments.

[0055] For example, the liquid supply mechanism 5 supplies a cooling medium into the first channel 11 of the base 1. The cooling medium cools the base 1 and the solid blades 3. If the temperature detector detects that the temperature of the solid blades 3 is too low, volatiles generated by the glass fiber roots will condense on the solid blades 3. Assuming that the airflow initially supplies hot air, the second controller first controls the pressure reducing valve to reduce the pressure based on the temperature signal from the temperature detector, and controls the opening of the flow regulating valve to increase the opening, thereby increasing the amount of hot air supplied. The hot air flows through the air outlet 41 onto the sidewalls of the corresponding solid blades 3, adjusting the temperature of the solid blades 3 so that the temperature of the solid blades 3 does not drop too low. The hot air is blown along the entire length of the solid blades 3, thereby regulating the temperature of the entire solid blades 3, thereby making the ambient temperature in the cooling area more uniform and facilitating the adjustment of the cooling intensity of the glass fiber roots. At the same time, the increased hot air volume increases the blowing force exerted on the volatiles in the glass fiber filaments, thereby blowing away the volatiles and preventing them from condensing on the solid blades 3.

[0056] On the contrary, if it is detected that the temperature of the solid blade 3 is high, assuming that the air supply mechanism initially supplies hot air, the second controller will control the opening of the flow regulating valve to decrease, reduce the amount of hot air supplied, and overall reduce the temperature at different positions of the solid blade 3, thereby reducing the ambient temperature in the cooling area more evenly.

[0057] Of course, the air supply mechanism can deliver hot air at a lower temperature or air at room temperature, depending on the ambient temperature within the cooling zone where the glass fiber filaments are located. For example, if the ambient temperature within the cooling zone is high, the air supply mechanism will deliver cold air at a lower temperature. This cold air is blown through the air outlet 41 in a direction toward one side surface of each corresponding solid blade 3, thereby lowering the temperature of the solid blade 3 and, in turn, the ambient temperature within the cooling zone.

[0058] Optimally, the above-mentioned air supply mechanism 2 also includes a heater to heat the external gas to the required temperature. The inlet of the high-pressure gas storage tank is sealed and connected to the outlet of the heating device. The heater is electrically connected to the second controller. The temperature detector also needs to detect the temperature of the gas in the intake pipe 121. The second controller controls whether the heater is turned on based on the temperature signal of the gas in the intake pipe 121 detected by the temperature detector.

[0059] like Figure 2 and Figure 3 As shown, one end of the air outlet component 4 extends in a straight line in the horizontal direction toward the other end; the length of the air outlet component 4 is less than the length of the corresponding solid blade, further ensuring that the gas blown out of the air outlet 41 of the air outlet component 4 is blown in parallel in the horizontal direction on the side surface of the corresponding solid blade 3, thereby adjusting the temperature of the solid blade 3.

[0060] In order to ensure that the gas blown out of the air outlet 41 of the air outlet component 4 can blow gas to the side wall of the corresponding solid blade 3, as shown in FIG. Figure 4 As shown, the air outlet components 4 are adjacent to or closely attached to a side wall of each corresponding solid blade 3 so that the air outlet components 4 blow a required amount of air onto a side surface of the solid blade 3 in a horizontal direction.

[0061] like Figure 4 As shown, at least one air outlet component 4 is distributed outside the two opposite side walls of each solid blade 3, that is, an air outlet component 4 is provided outside the two side walls of the solid blade 3, and the two air outlet components 4 adjust the temperature of one solid blade 3 at the same time, further improving the efficiency of blade temperature adjustment, and making the temperature at different positions of the solid blade 3 more uniform, thereby making the ambient temperature in the cooling area more uniform.

[0062] like Figure 3 As shown, at least two air outlet components 4 are evenly distributed in a row outside a side wall of the solid blade 3. That is, a row of air outlet components 4 is provided outside each side wall of each solid blade 3. The air outlet components 4 are evenly distributed in the height direction to synchronously adjust the temperature of the solid blade 3 at different heights, further ensuring a more uniform temperature at different positions of the solid blade 3, thereby making the ambient temperature in the cooling area more uniform, cooling the glass fiber roots more uniformly and with higher cooling intensity, and further dispersing volatiles at the glass fiber roots.

[0063] For example, Figure 3In the example, six air outlet components 4 are arranged in a row, blowing air onto the sidewall surface of one side of the solid blade 3. Of course, two or three air outlet components 4 can also be arranged in a row, with the specific number of air outlet components 4 being determined based on demand. Preferably, the height of a row of air outlet components 4 is slightly less than that of the solid blade 3, so that the row of air outlet components 4 can simultaneously blow air onto different heights of the same sidewall of the solid blade 3, achieving more uniform temperature adjustment and better cooling effect.

[0064] Or, as Figure 5 As shown, an air outlet component 4 is provided on one side surface of each solid blade 3 . At this time, optimally, the air outlet component 4 is distributed in the middle of the solid blade 3 .

[0065] For the air outlet component 4, if Figure 3 As shown, the air outlet component 4 is an air outlet pipe provided on the base 1. The base 1 is provided with a plurality of mounting holes connected to the second channel 12. One end of the air outlet pipe is inserted and fixed in the mounting holes, and the other end extends horizontally outward. Alternatively, the base 1 and the air outlet pipe are made of the same material, and one end of the air outlet pipe can be molded on the base 1 and connected to the second channel 12. Optimally, the air outlet pipe is a circular pipe, but it can also be a square pipe or any other shape.

[0066] Or, as Figure 7 As shown, the air outlet component 4 can also be an air outlet box. Preferably, the air outlet box is flat and distributed in a long strip shape in the height direction. The wind blown out from the air outlet 41 of the air outlet box can cover most areas of the solid blade 3 in height.

[0067] For the air outlet 41 of the air outlet box, if Figure 7 As shown, the air outlet 41 can be a single, long strip-shaped air outlet 41. Alternatively, Figure 8 As shown, there are two air outlets 41, and a partition is set in the inner cavity of the air outlet box to divide the air outlet 41 into two. Of course, the air outlet 41 can also be divided into three, four, etc., and the specific number of divisions is not limited.

[0068] Preferably, the thickness of the solid blade 3 can be selected from 1mm to 4mm, the height can be selected from 10mm to 20mm, and the length can be selected as needed. For example, the thickness can be 1mm, 2mm, 3mm, 4mm, etc., and the height can be 10mm, 12mm, 13mm, 15mm, 18mm, 19mm, 20mm. Alternatively, both the height and thickness can exceed the above ranges.

[0069] When the air outlet component 4 is an air outlet pipe, the inner diameter of the air outlet pipe can be preferably 0.5 mm to 2 mm, and the length can be designed as needed, but the length is less than the length of the solid blade 3. For example, the inner diameter can be 0.5 mm, 0.8 mm, 1.2 mm, 1.3 mm, 1.5 mm, 1.8 mm, 2 mm, etc., depending on actual needs.

[0070] When the air outlet component 4 is an air outlet box, the width of the air outlet box is also preferably 0.5mm-2mm, and the height can be selected from 3mm-20mm. For example, the height is 3mm, 5mm, 8mm, 10mm, 12mm, 13mm, 15mm, 18mm, 19mm, or 20mm. Alternatively, both the height and width may exceed the above ranges.

[0071] The sizes of the solid blades 3 and the air outlet component 4 need to be specifically designed according to the cooling temperature required in the cooling area and the air supply volume of the air supply mechanism 2 .

[0072] As a variation, in addition to the structure given above, the air outlet component 4 can also be an air outlet hole provided on the base 1.

[0073] As a variation, the air outlet component 4 can be arranged in the cooling area without being close to or adjacent to the side wall of the solid blade 3, and can be appropriately kept a certain distance away from the side wall of the solid blade 3, as long as the wind blown out from the air outlet 41 can be blown on one side surface of the solid blade 3.

[0074] Optimally, the first channel 11 is located below the second channel 12, that is, the gas flows in the second channel 12 above, and the cooling medium flows in the first channel 11 below. When the gas temperature is higher than the liquid temperature, the second channel 12 is above and the first channel 11 is below. Due to the low density of the gas, the gas flows in the second channel 12 near the top of the second channel 12; the cooling medium has a high density and flows in the first channel 11 near the bottom of the first channel 11. As a result, the heat exchange between the gas in the second channel 12 and the first channel 11 is relatively small, the heat loss is small, and most of the heat carried by the gas can act on the side wall surface of the solid blade 3. Of course, as a variation, the second channel 12 can be located below the first channel 11.

[0075] For the solid blade 3, preferably, the solid blade 3 is in the shape of a plate. There are many ways to fix the solid blade 3 to the base 1, preferably, as follows Figure 3 and Figure 7As shown, the top of the base 1 is provided with a notched slot, into which the first ends of the solid blades 3 are inserted in a one-to-one correspondence, with the second ends extending horizontally outward through the notch. Alternatively, other fixing methods can be used, such as welding the first ends of the solid blades 3 to the base 1, or providing mounting holes on the base 1, into which the first ends of the solid blades 3 are inserted and fixed.

[0076] Optimally, to accommodate on-site cooling of fiber roots from the bushing by the blade cooler, the tops of the solid blades 3 are higher than the top of the base 1, thus accommodating other structures at the fiber production site. Of course, if the on-site layout of the glass fiber production equipment changes, the tops of the solid blades 3 may also be lower than the top of the base 1.

[0077] Example 2

[0078] This embodiment provides a fiber preparation system, such as Figure 10 Shown, including

[0079] The bushing 6 is funnel-shaped, and a plurality of wire holes are provided at the bottom of the bushing;

[0080] In any one of the embodiments of the blade cooler provided in Example 1, the cooling area of ​​the blade cooler is distributed directly below the wire outlet hole.

[0081] For example, Figure 10 As shown, a plurality of nozzles 61 are provided at the bottom of the nozzle plate 6, each nozzle serving as a thread outlet, and the plurality of nozzles 61 form a plurality of thread outlets. The root 71 of the fiber filament 7 is located at the bottom of the nozzle, and the fiber filament 7 is located in the cooling area between two adjacent solid blades and is cooled.

[0082] The fiber filament preparation system of this embodiment includes a blade cooler of any one of the embodiments provided in Example 1, so that the fiber filaments are cooled evenly and with high cooling intensity and high cooling efficiency, and the volatile substances of the fiber filaments are blown away, thereby extending the service life of the solid blades 3 and the service life of the leak plate; it also improves product quality and production efficiency.

[0083] For example, when the air outlet component 4 is a blade cooler of an air duct and is used in a 1000-hole drawing plate or above, the fiber diameter variation coefficient of the raw silk with a fiber diameter of 9 microns is reduced by 15%-40%; the condensate removal time of the insert is more than doubled, and the life of the leak plate is extended by more than 15%.

[0084] When the air outlet component 4 is an air outlet box and used on an 800-hole drawing plate, the coefficient of variation of the fiber diameter of the raw yarn with a fiber diameter of 11 microns is reduced by 15%-35%. The condensate removal time of the insert is more than doubled, and the life of the plate is extended by more than 20%.

[0085] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
