Description

Technical Field

[0001] This utility model relates to the field of cooling technology for roller bearings of tempered glass heating furnaces, and in particular to a cooling device for ceramic roller support bearings of tempered glass heating furnaces. Background Technology

[0002] Tempered glass heating furnaces are crucial equipment in the tempered glass production process. These furnaces heat the glass internally via ceramic rollers supported by bearings on an outer bearing frame plate. During operation, heat is transferred outwards through the through-holes in the ceramic rollers and insulating bricks. This can cause excessive temperature rise in the supporting bearings, leading to lubrication loss, bearing failure, and ultimately, bearing seizure. This prevents the ceramic rollers from operating, easily causing scratches on the glass surface or even roller breakage, thus disrupting the normal operation of the tempered glass heating furnace. Utility Model Content

[0003] The purpose of this invention is to provide a cooling device for the ceramic roller support bearing of a tempered glass heating furnace, which is reliable in installation, low in cost, and has a good cooling effect.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a cooling device for the support bearing of ceramic roller conveyor of tempered glass heating furnace, including a vortex tube cooler fixedly installed relative to the roller conveyor frame. One end of the vortex tube cooler is connected to an air inlet pipe for conveying compressed air, and the other end of the vortex tube cooler is connected to the middle of a gas distribution pipe. Both ends of the gas distribution pipe are closed along its length. A plurality of nozzles are provided on one side of the gas distribution pipe. The plurality of nozzles are evenly spaced along the length of the gas distribution pipe. One end of each of the plurality of nozzles is connected to the side wall of the gas distribution pipe, and the other end of each of the plurality of nozzles is directed toward the support bearings of a plurality of adjacent rollers, so that the plurality of nozzles can cooperate to blow the cooling gas of the vortex tube cooler onto the surface of the plurality of support bearings.

[0005] Preferably, the vortex tube cooler is mounted on a support, which is placed on the roller conveyor frame.

[0006] Based on the above technical solution, the beneficial effects of this utility model are: This invention utilizes a vortex tube cooler for cooling, and then blows cold air simultaneously onto multiple support bearings through a distribution pipe and nozzles. The vortex tube cooler only requires the introduction of compressed air to convert it into both cold and hot air streams. The generated cold air stream is directed through the distribution pipe to cool the bearings, while the hot air stream is exhausted into the air. It is reliably installed, inexpensive to use, provides excellent cooling, increases bearing lifespan, and prevents lubrication failure due to excessive temperature rise in the support bearings of the ceramic roller conveyor, which could lead to bearing seizure and prevent the ceramic roller conveyor from rotating. It also prevents scratches on the glass surface and breakage of the ceramic roller conveyor, effectively ensuring the normal operation of the tempered glass heating furnace. Attached Figure Description

[0007] Figure 1 This is a three-dimensional schematic diagram of the present invention; Figure 2 for Figure 1 A sectional view; Figure 3 This is a front view of the vortex tube cooler and the gas distribution pipe.

[0008] The markings in the diagram are: 1. Roller frame, 2. Roller shaft, 3. Support bearing, 4. Inlet pipe, 5. Vortex tube cooler, 6. Air distribution pipe, 7. Nozzle, 8. Support. Detailed Implementation

[0009] Referring to the attached diagram, the specific implementation method is as follows: like Figure 1-3 As shown, a cooling device for the ceramic roller support bearing of a tempered glass heating furnace includes a vortex tube cooler 5 fixedly installed relative to the roller frame 1. Specifically, the vortex tube cooler 5 is mounted on a support 8, which is placed on the roller frame 1. One end of the vortex tube cooler 5 is connected to the air inlet pipe 4, and the other end is connected to the middle of the air distribution pipe 6.

[0010] Compressed air can be input into the vortex tube cooler 5 through the intake pipe 4. The vortex tube cooler 5 can convert the compressed air into cold air and hot air, and can guide the generated cold air into the air distribution pipe 6, while drawing out the hot air and discharging it into the air.

[0011] like Figure 1-3 As shown, both ends of the gas distribution pipe 6 are closed along its length. Three nozzles 7 are provided on one side of the gas distribution pipe 6. The three nozzles 7 are evenly spaced along the length of the gas distribution pipe 6. One end of each of the three nozzles 7 is connected to the side wall of the gas distribution pipe 6. The other ends of the three nozzles 7 are respectively directed toward the support bearings 3 of the three adjacent rollers 2, so that the three nozzles 7 can cooperate to blow the cooling gas of the vortex tube cooler 5 toward the surface of the three support bearings 3.

[0012] This embodiment is reliably installed, has low operating costs, and provides excellent cooling. Based on the length of the ceramic roller conveyor in the tempered glass heating furnace, multiple cooling devices can be easily installed on both sides of the roller conveyor to ensure that all supporting bearings on both sides are cooled by airflow. This increases bearing life and prevents excessive temperature rise in the supporting bearings of the ceramic roller conveyor, which could lead to lubrication failure, bearing seizure, and the inability of the ceramic roller conveyor to rotate. It also prevents scratches on the glass surface and breakage of the ceramic roller conveyor, effectively ensuring the normal operation of the tempered glass heating furnace.

[0013] In this invention, the specific length of the air distribution pipe 6 can be flexibly set according to the cooling effect of the bearings. That is, the air distribution pipe 6, which in the embodiment has three nozzles 7, can be lengthened, and the number of nozzles 7 can be increased accordingly. One air distribution pipe 6 can simultaneously blow air through four or five nozzles 7, thus cooling a larger number of support bearings 3. In this case, the cooling airflow temperature is lower and the flow rate is higher closer to the middle of the air distribution pipe 6 where it connects to the vortex tube cooler 5, resulting in a stronger cooling effect. Conversely, the cooling airflow temperature is higher and the flow rate is lower closer to the sides of the air distribution pipe 6. This means that the cooling effect of the nozzles 7 near the sides of the air distribution pipe 6 on the support bearings 3 is relatively reduced. Therefore, the length of the air distribution pipe 6 and the number of nozzles 7 need to be set according to the actual situation.
