Description

Technical Field

[0001] The utility model relates to a sealing device, in particular to a sealing device for a single-nozzle nodulation cleaning hole of a flash smelting furnace. Background Technique

[0002] In the process of copper pyrometallurgy, the flash smelting technology mainly extracts copper matte powder into high-grade blister copper. During the flash smelting process, it is necessary to ensure that the powdery material falls evenly and stably in the central injector. However, affected by the change of material properties during the production process, nodules will appear under and around the bottom plate of the distributor. The nodules will cause uneven reaction and the problem of downward raw material in the production process. At the same time, the existence of nodules directly affects the efficient operation of the single nozzle of the smelting furnace and the furnace condition control. In the prior art, for the convenience of nodulation cleaning, a nodulation cleaning hole is opened in the surrounding water jacket under the bird's nest water jacket of the single nozzle, which is convenient for cleaning the nodules during the production process.

[0003] Among them, a sealing device is provided on the nodulation cleaning hole. However, the plug used in the existing sealing device has a short size, resulting in that the plug cannot fit the nodulation cleaning hole during use, which will cause nodules to form at the nodulation cleaning hole. And when more nodules are bonded, they will also be bonded to the plug together. When it is necessary to clean the nodules, it is difficult to take out the plug. If it cannot be solved in a short time, it will cause the phenomenon of stopping the material for cleaning, which will affect the overall production progress. Summary of the Invention

[0004] Aiming at the deficiencies that the plug has a short size, cannot fit the nodulation cleaning hole during use, has a poor sealing effect, and the nodules will also be bonded to the plug together, resulting in the plug being difficult to take out, the utility model provides a sealing device for a single-nozzle nodulation cleaning hole of a flash smelting furnace, which has a simple structure, can better fit the nodulation cleaning hole during use, and is convenient to take out.

[0005] To achieve the above object, the technical solution of the utility model is as follows:

[0006] A sealing device for a single-nozzle nodulation cleaning hole of a flash smelting furnace includes a pull rod, a handle, a plug and an iron seal ring made of carbon steel; one end of the pull rod is welded to the handle to form a T shape, and the other end is detachably connected to a cylindrical hollow plug; the top surface of the plug is connected with the iron seal ring; the iron seal ring is circular, the inner ring is connected with the pull rod in a matching manner, and the bottom surface is fixedly connected with the top surface of the plug.

[0007] The device components are made of carbon steel, with relatively high overall rigidity. The length of the pull rod can be selected according to actual operation requirements; the plug is detachable and can be matched with the pull rod, and the plug can be selected according to the size of the actual nodule-sealing hole, which is convenient for the sealing device to adapt to nodule-cleaning holes of different sizes; when in use, the worker holds the handle and manipulates the pull rod to insert the plug into the nodule-cleaning hole. After the plug is inserted, the cylindrical structure fits with the nodule-cleaning hole. At the same time, the iron seal ring above the plug fits with the surface around the nodule-cleaning hole, with a large contact area, realizing the sealing of the hole and avoiding the escape of smelting flue gas and the formation of nodules in the nodule-cleaning hole; then when cleaning the generated nodules, operate the pull rod to pull up the plug. If it is difficult to remove the plug at this time, it means that nodules have formed at the connection part between the iron seal ring of the plug and the surrounding water jacket, resulting in the connection of this part. At this time, hold both ends of the handle and rotate the device around the pull rod point, so that there is looseness between the iron seal ring and the plug and the surrounding water jacket, and the iron seal ring and the surrounding water jacket can be quickly separated. At this time, the plug can be easily taken out.

[0008] Further, the diameter of the plug is 100mm and the height is 150mm. The plug of this size can better fit the nodule-cleaning hole of the annular water jacket in use in the factory. Since the size of the plug fits the size of the hole, the problem that nodules will form in the nodule-cleaning hole and cause the plug to bond with the nodule-cleaning hole is solved.

[0009] Further, a groove for matching with the pull rod is provided at the top of the plug, and countersunk screws are provided on the side; a circular ring-shaped connection groove for matching with the countersunk screws is provided at the bottom of the pull rod. When in use, first insert the pull rod into the groove, and then tighten the countersunk screws. The countersunk screws pass through the plug and are inserted into the circular ring-shaped connection groove, so that the two are stably connected together, which is convenient for the use of the sealing device.

[0010] Further, internal threads are provided on the inner ring of the iron seal ring; external threads for matching with the internal screws are provided at the position where the pull rod is connected to the iron seal ring. The iron seal ring and the pull rod are tightened by clockwise rotation of the threads, and the connection between the two is more stable and reliable. When the sealing device is in use, the worker can rotate the handle clockwise to rotate without affecting the thread fit between the seal ring and the pull rod, which is convenient for taking out the plug.

[0011] Further, a heat-insulating and anti-slip sleeve is sleeved on the handle. The heat-insulating and anti-slip sleeve facilitates the holding and use of the device.

[0012] Further, a layer of fiberglass paper is sleeved on the periphery of the plug. The fiberglass paper on the periphery of the plug can make the plug fit closely with the nodule-cleaning hole, and the fiberglass paper is heat-resistant. Using it on the periphery of the plug can improve the sealing effect of the sealing device.
