Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices in industrial processing, specifically a rolling oil flat bed filtration device. Background Technology

[0002] During the rolling process of a cold rolling mill, the rolling oil is continuously circulated. During this process, impurities such as metal scraps, aluminum powder, and oil-aluminum compounds can become mixed in. If these impurities are not filtered out in time, they can clog the oil nozzles, create roller marks, and even affect product quality. Therefore, filtering the rolling oil is essential to maintain its cleanliness and performance.

[0003] Existing filtration systems separate impurities from rolling oil using the principle of solid-liquid separation. This is typically achieved by placing a filter basket inside the pipe. However, existing filter baskets do not fit tightly against the inner wall of the pipe, allowing some tiny debris to leak out through the gaps, affecting the filtration effect. Furthermore, cleaning the filter basket requires stopping the machine, reducing production efficiency.

[0004] The reason for this problem is that existing filtration devices, in order to ensure fluid flow and ease of removal and replacement, do not allow the filter basket to fit tightly against the inner wall of the cleaning pipe. Furthermore, the rolling oil causes the filter basket to move, resulting in some debris entering the conduit through the gap between the filter basket and the cleaning pipe during the filtration of the rolling oil, scratching or even clogging the machine parts. Therefore, we propose a new type of rolling oil flat bed filtration device to solve the above problems. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] This application provides a rolling oil flat bed filter device, which solves the problems of existing filter baskets not fitting tightly against the inner wall of the pipe, allowing some tiny debris to flow out through the gaps, affecting the filtration effect, and requiring the machine to be stopped when cleaning the filter basket, thus reducing production efficiency.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] This utility model discloses a rolling oil flat bed filtration device.

[0024] According to the appendix Figure 1-4 As shown, it includes a filter unit 1, which is composed of a feed pipe 11 and a guide pipe 12. Fixed filter mechanisms 2 are provided on both sides of the guide pipe 12. The fixed filter mechanism 2 includes a cleaning pipe 21, a filter basket 22 and a sealing positioning ring 23.

[0025] The operating principle of this device is as follows: Rolling oil is injected into the feed pipe 11 and guided into the conduit 12 by the three-way ball valve 3. The rolling oil then flows into the cleaning pipe 21 through the conduit 12. Impurities carried within the fluid are blocked by the filter basket 22 and, under the influence of gravity, fall to the bottom of the filter basket 22 and are collected. After filtration, the rolled oil flows into the machine through the other conduit 12, completing the filtration process. When the filter basket 22 needs to be replaced, the three-way ball valve 3 is rotated, guiding the rolling oil into the other conduit 12. Excess rolling oil then flows into the cleaning pipe 21 and drains through the drain port at its bottom. The outflow is collected. Remove the flange at the top of the cleaning tube 21. Pull the gripping blocks 2334 on both sides toward the central axis. The spring 2333 is tightened, causing the insertion rod 2332 to disengage from the inside of the cleaning tube 21. Remove the sealing positioning ring 23 entirely from the inside of the cleaning tube 21. Remove the filter basket 22 for cleaning or replacement. Place the cleaned or replaced filter basket 22 into the feed tube 11. Snap the sealing positioning ring 23 onto the top of the filter basket 22. Release the gripping blocks 2334. Under the reaction force of the spring 2333, the insertion rod 2332 is inserted into the inside of the cleaning tube 21, completing the fixation of the filter basket 22.

[0026] The filter basket 22 is located inside the cleaning tube 21, and the sealing positioning ring 23 is movably engaged with the top of the filter basket 22;

[0027] The inner wall of the sealing positioning ring 23 is provided with snap-fit ​​fasteners 233 on both sides, and the sealing positioning ring 23 is movably snapped with the cleaning tube 21 through the snap-fit ​​fasteners 233.

[0028] The sealing positioning ring 23 also includes a fixing ring 231 and a sealing strip 232; the fixing ring 231 is slidably connected to the inside of the cleaning tube 21, and the sealing strip 232 is fixedly connected to the outer wall of the fixing ring 231. The outer surface of the sealing strip 232 is in close contact with the inner wall of the cleaning tube 21. The fixing ring 231 is made of a rigid material, which enables it to effectively fix the position of the filter basket 22. The sealing strip 232 fills the gap between the filter basket 22 and the cleaning tube 21, which effectively improves the filtration quality and ensures that the debris carried inside the fluid will not enter the machine through the gap.

[0029] The snap-fit ​​fastener 233 includes a fixing block 2331 and a plug rod 2332; the fixing block 2331 is fixedly connected to the inner wall of the sealing positioning ring 23, the plug rod 2332 passes through the fixing block 2331, and one end of the plug rod 2332 is movably snapped into the interior of the cleaning tube 21. The snap-fit ​​fastener 233 also includes a spring 2333 and a gripping block 2334; the spring 2333 is wound around the outer surface of the plug rod 2332, the gripping block 2334 is fixedly connected to the other end of the plug rod 2332, one end of the spring 2333 is fixedly connected to the plug rod 2332, and the other end of the spring 2333 is fixedly connected to the other end of the plug rod 2332. One end is fixedly connected to the fixing block 2331. A three-way ball valve 3 is rotatably connected inside the connection between the feed pipe 11 and the guide pipe 12. The inner wall of the cleaning pipe 21 has a fixing hole. The filter basket 22 is fixed by the sealing positioning ring 23. The insert rod 2332 inside can be directly inserted into the inside of the fixing hole. The spring 2333 provides a pushing force to the insert rod 2332, so that it can be fixed inside the fixing hole, while also ensuring that the insert rod 2332 will not slip out of the fixing block 2331 and affect the fixing of the filter basket 22, thus ensuring the normal use of the device.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
