Description

Technical Field

[0001] The utility model relates to the technical field of hot roller cooling, in particular to a hot roller cooling device. Background Art

[0002] In the production process of polyester industrial yarn, in order to give the fiber good bundling, smoothness and antistatic properties, to reduce the generation of lint and broken ends, to improve the spinnability of the fiber, and to ensure the dyeing uniformity and post-processing properties of the fiber, the fiber tow needs to be oiled before entering the hot roller.

[0003] The fiber bundle with oil on the surface is stretched and shaped by high-temperature, high-speed hot rollers (where the hot roller temperature is 220~260℃ and the spinning speed is 2700~6000m / min). At this time, the volatilization of the oil will leave oil stains on the hot rollers. The presence of oil stains not only deteriorates the heat transfer effect between the filament bundle and the hot roller, but also increases the friction. The poor heat transfer effect will increase the dry heat shrinkage of the filament bundle, affect the quality and performance of the product, and be detrimental to post-processing production. At the same time, under high-speed rotation, the increased friction can easily cause the single filament to break and wrap around the hot roller, resulting in lint and broken ends. During the production process, the hot roller must be cleaned regularly every 8~24 hours to remove the oil stains on the hot roller and lint caused by friction.

[0004] The current cleaning process is as follows: first, wrap the hot roller with a cooling cloth soaked in deionized water. This step needs to be repeated several times to cool the hot roller to below 100°C. Then, scrub the surface of the hot roller with alkaline solution, and then scrub the hot roller clean with deionized water. Because the ambient temperature is high when the hot roller is cooled, a large amount of water vapor is generated, which is difficult for workers to endure for a long time, resulting in a high job mobility problem. There is an urgent need for a device to reduce the temperature of the hot roller and reduce the intensity of employees' work. Utility Model Content

[0006] The utility model provides a hot roller cooling device, comprising a cooling jacket, the cooling jacket consisting of at least two flange rings and an intermediate sleeve, a spray pipe being provided on the upper portion of the sleeve, a plurality of spray ports being equidistantly provided on the bottom of the spray pipe, and a water collecting tank being provided on the lower portion of the sleeve.

[0007] Preferably, the spray pipe and the water collecting tank are respectively provided with a first threaded interface and a second threaded interface, and one end of the first threaded interface is connected to the water outlet of the circulation pump through a connecting pipe.

[0016] Compared with the prior art, the present invention provides a hot roller cooling device:

[0017] 1. The utility model uses a circulating pump to draw deionized water from the water tank and inject it into the spray pipe on the upper part of the cooling jacket of the hot roller. The water is sprayed onto the surface of the cooling hot roller through the spray port. A small part of the deionized water evaporates at high temperature and takes away the heat energy, while most of it is collected in the return water tank at the lower part of the cooling jacket and flows back to the water tank.

DETAILED DESCRIPTION

[0031] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0032] Please refer to Figures 1-9 The embodiment of the utility model provides a hot roller cooling device, including a cooling jacket, which is composed of at least two flange rings 2 and an intermediate sleeve 1. A spray pipe 8 is provided on the upper part of the sleeve 1, and a plurality of spray ports 9 are equidistantly provided at the bottom of the spray pipe 8. A water collecting tank 4 is provided at the lower part of the sleeve 1.

[0033] Specifically, the sleeve 1, flange ring 2 and spray pipe 8 are all made of stainless steel. The sleeve 1 is bent from stainless steel. There are four flange rings 2, two in a group, which are respectively connected to the two ends of the sleeve 1. The flange ring 2 and the sleeve 1 are fixed by welding. The flange ring 2 is 30mm wide. A DN15mm spray pipe 8 is welded to the front flange. A row of 2mm spray ports 9 are evenly opened at the bottom of the spray pipe 8.

[0034] Furthermore, since the stainless steel bending parts are relatively heavy as a whole and the diameter of the circle is designed to be 8mm larger than the size of the hot roller, when they are put on the hot roller, they hit the hot roller when they are not parallel and tilted, which poses a risk of damaging the surface coating of the hot roller. The middle stainless steel bending material can be replaced by silicone cloth, which not only makes it convenient for staff to operate, but also avoids damage to the surface of the hot roller.

[0035] The spray pipe 8 and the water collecting tank 4 are respectively provided with a first threaded interface 81 and a second threaded interface 41. One end of the first threaded interface 81 is connected to the water outlet of the circulation pump 12 through a connecting pipe 10, and the second threaded interface 41 is connected to the water inlet of the water storage tank 11 through a connecting pipe 10. The water outlet of the water storage tank 11 is connected to the water inlet of the circulation pump 12 through a connecting pipe 10, and the circulation pump 12 is connected to the external power supply 13.

[0036] Specifically, the first threaded interface 81 and the second threaded interface 41 are both three-point internal threads. When in use, after the hot roller stops, the hot roller cooling jacket is put on the hot roller, the cooling jacket is connected to the cooling pipeline, and the circulating pump 12 is turned on. The circulating pump 12 draws deionized water from the water tank 11 and injects it into the spray pipe 8 on the upper part of the hot roller cooling jacket, and sprays it onto the surface of the cooling hot roller through the spray port 9. A small part of the deionized water evaporates at high temperature and takes away heat energy, and most of it is collected in the return water tank at the bottom of the cooling jacket and flows back to the water tank 11. In this way, the surface temperature of the hot roller is continuously reduced. Generally, the surface temperature of the hot roller with a temperature of 250°C can be reduced to below 100°C in 3 minutes, thereby improving the cooling efficiency of the hot roller and reducing the labor burden.

[0037] A long slot 7 is provided on the upper portion of the sleeve 1 , and guard plates 71 are fixedly connected to both sides of the long slot 7 . A spray pipe 8 is arranged in the long slot 7 and fixedly connected to the flange ring 2 .

[0038] Specifically, the spray pipe 8 is welded and fixed to the flange ring 2. The provision of the guard plate 71 can prevent the cooling water from splashing and can also protect the spray pipe 8 to prevent the spray pipe 8 from being hit during movement and causing the welding to become loose.

[0039] The flange rings 2 are connected to both ends of the sleeve 1. The flange rings 2 at both ends are fixed with silicone rings 3 by several bolts 6. The silicone ring 3 is installed between the two flange rings 2 and has a thickness of 1mm, which can ensure the sealing of the connection between the flange rings 2.

[0040] A handle 5 is fixedly connected to both sides of the flange ring 2 at one end. The staff moves the cooling jacket through the handle 5 to put the cooling jacket on the hot roller or remove it from the hot roller.

[0041] A cleaning mechanism is provided on one side of the spray pipe 8, and the cleaning mechanism includes a cleaning brush 14 and several guide rods 16. The cleaning brush 14 is arranged in the long groove 7, and several guide rods 16 are fixedly connected to one side of the cleaning brush 14. The guide rod 16 slides through the guard plate 71 on one side and the end is fixedly connected to the connecting rod 15. A spring 17 is sleeved on each guide rod 16, and the two ends of the spring 17 are fixedly connected to the guard plate 71 and the connecting rod 15 respectively.

[0042] Specifically, the initial position of the cleaning brush 14 is located on one side of several spray ports 9. Before each spraying, the connecting rod 15 is pushed to drive the guide rod 16 and the cleaning brush 14 to move, so that the cleaning brush 14 cleans the spray port 9. Then the cleaning brush 14 is reset under the elastic force of the spring 17. Repeating this several times can ensure that the spray port 9 is not blocked by debris, ensure that each spray port 9 discharges water normally, effectively avoid debris clogging the spray port 9, and ensure the cooling effect.

[0043] In summary, the working principle of a hot roller cooling device according to an embodiment of the present invention is as follows:

[0044] Push the connecting rod 15 to drive the guide rod 16 and the cleaning brush 14 to move, so that the cleaning brush 14 cleans the spray port 9. Then the cleaning brush 14 is reset under the elastic force of the spring 17. Repeat this several times to ensure that the spray port 9 is not blocked by debris and that each spray port 9 has normal water discharge.

[0045] After the hot roller stops, put the hot roller cooling jacket on the hot roller, connect the water inlet and return pipes on the hot roller cooling jacket, connect the other end of the water inlet pipe to the water outlet of the circulation pump 12, the water inlet of the circulation pump 12 is connected to the water outlet at the bottom of the water tank 11, and the other end of the return pipe of the hot roller cooling jacket is connected to the water inlet at the upper part of the water tank 11. Turn on the power 13 to make the circulation pump 12 work. The circulation pump 12 draws deionized water from the water tank 11 and injects it into the spray pipe 8 on the upper part of the hot roller cooling jacket, and sprays it onto the surface of the cooling hot roller through the spray port 9. A small part of the deionized water evaporates at high temperature and takes away the heat energy, and most of it is collected in the return water tank at the bottom of the cooling jacket and returned to the water tank 11. This continuous circulation reduces the surface temperature of the hot roller. Generally, the surface temperature of the hot roller with a temperature of 250°C can be reduced to below 100°C in 3 minutes.

[0046] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
