Description

Technical Field

[0001] The utility model relates to the technical field of tube plate cleaning, in particular to a cleaning device for tube plates. Background Art

[0002] A tube sheet is a fitting with holes drilled on a circular steel plate that are slightly larger than the outer diameter of the tube. It is mainly used to fix tubes and seal media in heat exchangers. During the use of the tube sheet, rust, sediment, dirt and oxide impurities may accumulate on the surface. These impurities not only affect the appearance of the tube sheet, but may also affect the subsequent process. Therefore, it is often necessary to use a cleaning device to grind off the impurities. The cleaning device is generally equipped with a grinding wheel for grinding impurities. Through grinding, these impurities can be effectively removed, making the tube sheet surface flatter and smoother.

[0003] The cleaning device has limited working stations and can generally only grind a single tube sheet. Within a limited time, the number of tube sheets cleaned is small, which reduces the efficiency of the cleaning device. After the tube sheet is polished, the staff needs to manually move the tube sheet and unload it, which is quite physically demanding. Therefore, it is particularly important to design a cleaning device for the tube sheet. Utility Model Content

Example 2:

[0023] Based on the first embodiment, Figure 1 and Figure 4As shown, one side of the two arc-shaped plates 10 is fixedly connected to one side of the two L-shaped blocks 9, respectively. The outer surfaces of the two tube sheet members 3 are in contact with the inner surfaces of the two arc-shaped plates 10, respectively. A blanking box 12 is provided inside the two L-shaped frames 11. The interiors of the two blanking boxes 12 are filled with sponges. One side of the two U-shaped plates 14 is provided with multiple abutment rods 13. The utility model provides a cleaning device for tube sheets, which is provided with a belt 7, a pulley, an L-shaped block 9 and an L-shaped frame 11. The two pulleys are driven by the belt 7. As the first screw rod 4 rotates, the second screw rod 5 is driven to rotate, and the threads opened on the surfaces of the two are opposite, so that the convex plate 8 threaded therewith can be driven to move in the opposite direction.

[0024] Working principle: Tube sheet is a kind of accessory with holes slightly larger than the outer diameter of the tube drilled on a circular steel plate. It is mainly used to fix the tubes and seal the medium in the heat exchanger. During the use of the tube sheet, rust, sediment, dirt and oxide impurities may accumulate on the surface. These impurities not only affect the appearance of the tube sheet, but also may affect the subsequent process. Therefore, it is often necessary to use a cleaning device to grind the impurities. The cleaning device is generally equipped with a grinding wheel for grinding the impurities. By grinding, these impurities can be effectively removed, making the tube The plate surface is more flat and smooth. The use of two curved plates 10 to push the tube sheet 3 not only increases the station for tube sheet cleaning, but also can actively unload the polished tube sheet 3. After the two tube sheet 3 are placed on both sides of the cleaning seat 1, the outer surface of the tube sheet 3 and the inner surface of the curved plate 10 are in contact with each other. The curved plate 10 can push the tube sheet 3. Then, the staff can start the servo motor 6. After starting the servo motor 6, it will drive the first screw rod 4 to rotate synchronously. Under the action of the belt 7, the second screw rod 5 As it rotates, the two convex plates 8 can move relative to each other, driving the L-shaped block 9 to move, and also driving the curved plate 10 to move. The curved plate 10 gradually pushes the tube sheet 3 located on the side to the bottom of the grinding wheel 2, so as to facilitate comprehensive grinding and cleaning of the surface of the tube sheet 3, and then continues to push the tube sheet 3 outward. After the bottom surface of the tube sheet 3 and the surface of the cleaning seat 1 are suspended in the air, they will fall downward under the action of inertia, and then fall into the interior of the blanking box 12 for collection. The U-shaped plate 14 increases the range of blocking the tube sheet 3, avoiding the tube sheet 3 from being blocked. When the plate 3 is unloaded, it falls to the outside and is damaged. The two pulleys are driven by the belt 7. As the first screw 4 rotates, the second screw 5 is driven to rotate, and the threads opened on the surfaces of the two are opposite, so they can drive the convex plate 8 with which they are threaded to move in the opposite direction. The L-shaped frame 11 and the U-shaped plate 14 are connected by multiple abutment rods 13, and the sponge can reduce the impact of the tube plate 3 on the inner surface of the blanking box 12 when unloading, thereby preventing the surface of the tube plate 3 and the blanking box 12 from being dented, and improving the efficiency of the cleaning device.
