Description
Technical Field
[0001] This utility model relates to the field of water return from internal cooling rollers, and in particular to a water return device and system based on internal cooling rollers. Background Technology
[0002] Currently, domestic metallurgical plants and mines lack effective control measures for water ingress into the bearing housings of internal cooling rollers. In field operations, the common approach is to add a seal or step to one end of the roller shaft to alleviate the water ingress problem. However, even after adopting this measure, the effect is still unsatisfactory, and water ingress into the bearing housings of internal cooling rollers still exists, which can easily lead to bearing damage and roller shaft jamming, resulting in unnecessary downtime and increased production costs.
[0003] To address the above problems, the inventors have designed a water return device and system based on an internal cooling roller. Utility Model Content
[0004] To address the aforementioned technical problems, a water return device and system based on an internal cooling roller is provided. This invention is ingeniously designed and has a simple structure, effectively solving the water ingress problem in the bearing housing of the internal cooling roller, ensuring the service life of the bearings and roller shaft, and meeting on-site application requirements. The technical means employed in this invention are as follows:
[0005] In a first aspect, a water return device based on an internal cooling roller includes a water collection mechanism; the water collection mechanism includes a water collection cylinder, a roller bearing seat, and a water pipe seat. The water collection cylinder is a cylindrical structure with its axis parallel to a horizontal plane. The roller bearing seat is an annular structure. The inner diameter of the roller bearing seat is smaller than the inner diameter of the water collection cylinder but larger than the outer diameter of the roller bearing of the internal cooling roller. The outer diameter of the roller bearing seat is larger than or equal to the outer diameter of the water collection cylinder. The inner diameter of the water pipe seat is smaller than the inner diameter of the water collection cylinder but larger than or equal to the outer diameter of the water pipe of the internal cooling roller. The outer diameter of the water pipe seat is larger than or equal to the outer diameter of the water collection cylinder. The roller bearing seat and the water pipe seat are coaxially mounted on both ends of the water collection cylinder. The device also includes a water blocking mechanism and a water return mechanism. The water-blocking mechanism includes a water-blocking plate, which is a circular ring structure. The inner diameter of the water-blocking plate is smaller than the inner diameter of the water collecting cylinder and larger than the outer diameter of the inner cooling roller shaft. The outer diameter of the water-blocking plate is equal to the inner diameter of the water collecting cylinder. The water-blocking plate is coaxially installed inside the water collecting cylinder. The water return mechanism includes a first water return pipe and a second water return pipe. One end of the first water return pipe is located above the other end, and one end of the second water return pipe is located above the other end. The top end of the first water return pipe is connected to the portion of the bottom surface of the water collecting cylinder located between the roller shaft seat and the water-blocking plate. The top end of the second water return pipe is connected to the portion of the bottom surface of the water collecting cylinder located between the water pipe seat and the water-blocking plate.
[0006] Furthermore, it also includes an exhaust observation mechanism; the exhaust observation mechanism includes an exhaust observation hole, which is a cylindrical through hole with its axis perpendicular to the horizontal plane; the exhaust observation hole is opened on the top surface of the water collecting cylinder, on the part between the water pipe seat and the baffle plate.
[0007] In a second aspect, a water return system based on an internal cooling roller includes an internal cooling roller; the internal cooling roller includes a roller body, a roller shaft, a bearing, a bearing seat, and a water pipe. The roller body is a cylindrical structure with its axis parallel to a horizontal plane. The roller shaft is a cylindrical structure with its outer diameter equal to the inner diameter of the roller body. The bearing is an annular structure with its inner diameter equal to the outer diameter of the roller shaft. The bearing seat is an annular structure with its inner diameter equal to the outer diameter of the bearing. The water pipe is a cylindrical structure with its outer diameter smaller than the inner diameter of the roller shaft. The roller shaft is coaxially and continuously installed inside the roller body. The bearing is coaxially sleeved outside the roller shaft. The bearing seat is coaxially sleeved outside the bearing. One end of the water pipe is coaxially installed inside the roller shaft. The system also includes a water return device based on an internal cooling roller as described in any one of the first aspects. In the water return device based on an internal cooling roller, both the roller shaft seat and the baffle plate are coaxially sleeved outside the roller shaft. In the water return device based on an internal cooling roller, the water pipe seat is coaxially sleeved outside the other end of the water pipe.
[0008] This utility model has the following advantages:
[0009] 1. In this utility model, the roller shaft of the inner cooling roller is coaxially passed through the roller shaft seat and the baffle plate, and the water pipe of the inner cooling roller is coaxially passed through the water pipe seat. During the actual operation of the inner cooling roller, the cooling water will flow out through the gap between the roller shaft and the water pipe and collect in the water collecting cylinder in the part between the baffle plate and the water pipe seat. At this time, the baffle plate can block the cooling water from flowing to the roller shaft seat, thereby preventing the cooling water from entering the bearing seat through the roller shaft seat. The cooling water in the water collecting cylinder will be discharged to the outside of the water collecting cylinder through the first return water pipe and the second return water pipe, thereby ensuring that too much cooling water will not accumulate in the water collecting cylinder, further preventing the cooling water from entering the bearing seat through the roller shaft seat.
[0010] 2. In this utility model, the gas inside the water collecting cylinder can be discharged to the outside of the water collecting cylinder through the exhaust observation hole to avoid excessive pressure inside the water collecting cylinder; in addition, the staff can observe the liquid level of the cooling water inside the water collecting cylinder through the exhaust observation hole.
