Description

Technical Field

[0001] The utility model relates to the technical field of copper smelting, and particularly relates to a dust cleaning device for a spherical flue and a hopper in copper smelting. Background Art

[0002] In the industrial production of copper smelting, the flue gas generated during the furnace smelting process contains a large amount of soot, and these soot need to be removed by dust removal equipment during the flue gas treatment process. The dust removal equipment usually includes a flue and a hopper, which are important components in the flue gas treatment system. The flue is responsible for guiding the flow of flue gas, while the hopper collects the soot in the flue gas. However, during the actual installation and use process, since the hopper needs to be installed on the structural beam or the horizontal section of the flue, soot is likely to accumulate at these positions, resulting in the problem of internal ash accumulation.

[0003] Internal ash accumulation will not only increase the maintenance cost and labor intensity of the equipment, but also reduce the cross-sectional area of the flue and the hopper due to excessive ash accumulation, affecting the negative pressure of the system, and further leading to poor smoke exhaust. This situation will seriously affect the continuity and stability of copper smelting industrial production, and may even cause safety accidents. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a dust cleaning device for a spherical flue and a hopper in copper smelting, which can efficiently clean ash, make the flue smoke exhaust smoothly, improve the stability of copper smelting, is simple to operate, and reduces the manual labor intensity, so as to solve the technical problem that when the existing flue discharges flue gas, ash accumulation points are likely to occur, resulting in a smaller cross-sectional area of the flue, affecting the negative pressure of the system, and further leading to poor smoke exhaust, affecting the stability of copper smelting or causing safety accidents.

[0005] In order to solve the above technical problems, the following solutions are adopted in the utility model:

[0006] A dust cleaning device for a spherical flue and a hopper in copper smelting, which is used to clean the inside of the flue, includes a cycloidal pinwheel speed reducer, a bearing seat, a sealing gland flange, a dust cleaning plate and a transmission shaft; the transmission shaft penetrates through the flue; the bearing seat includes bearing seat A and bearing seat B, which are respectively installed at both ends of the transmission shaft to support and limit both ends of the transmission shaft; the output end of the cycloidal pinwheel speed reducer is connected to the transmission shaft to drive the transmission shaft to rotate; there are two sealing gland flanges, which are respectively installed at the hopper openings at both ends of the flue; the dust cleaning plate is installed on the transmission shaft, and the width thereof matches the inside of the flue. The width of the dust cleaning plate is adjusted according to the installation height of the speed reducer and the distance from the lower part of the ash accumulation point. The cycloidal pinwheel speed reducer drives the transmission shaft to rotate, and then drives the dust cleaning plate to rotate to clean the ash accumulation point of the flue. The whole is externally connected to a controller and a power supply.

[0007] Further, the cycloid pinwheel speed reducer is provided with a speed reducer support; the top end of the speed reducer support is connected to the cycloid pinwheel speed reducer. The speed reducer support and the cycloid pinwheel speed reducer are fixedly connected by bolts, and the height of the cycloid pinwheel speed reducer is adjusted to a position parallel to the ash hopper openings at both ends of the flue, which is convenient for driving the transmission shaft to rotate.

[0008] Further, the sealing gland flange includes flange A, flange B and connecting bolts; flange B is fixedly connected to the ash hopper opening of the flue; flange A is connected to flange B through the connecting bolts. Flange B is welded at the ash hopper opening of the flue, and flange A is connected to flange B through connecting bolts to seal the penetration part of the transmission shaft and prevent flue gas from escaping from the penetrated part of the flue.

[0009] Further, the sealing gland flange is provided with a gasket; the gasket is located between flange A and flange B. The gasket is placed between the two flange plates to play a sealing role and further reduce the occurrence of flue gas leakage.

[0010] Further, the connecting bolts are provided with packing sealing materials. The packing sealing materials are filled in the space inside the flange opening matching the connecting bolts. When the connecting bolts are tightened, the packing materials will be compressed and closely attached to the surface of the connecting bolts, thereby forming an effective sealing layer to prevent flue gas from leaking from the connection.

[0011] Further, the ash cleaning plate is provided with reinforcing rib plates; there are several reinforcing rib plates, which are evenly distributed on the ash cleaning plate. The ash cleaning plate is intermittently welded with reinforcing rib plates, which can improve the overall strength of the ash cleaning plate and prevent the ash cleaning plate from breaking when rotating to clean the soot.

[0012] The working principle of the present utility model is as follows:

[0013] During use, the cycloid pinwheel speed reducer is installed on one side of the flue ash hopper housing through the speed reducer support and connected to the transmission shaft. The cycloid pinwheel speed reducer is started to drive the transmission shaft to rotate, and then drive the ash cleaning plate to rotate to clean the ash accumulation points in the flue. The soot cleaned falls into the lower ash hopper and is transported to the silo pump through the scraper conveyor connected to the ash hopper, and then pneumatically transported to the top ash bin of the furnace and used as the raw material for the furnace to return to the furnace. The flange A, flange B and gasket of the sealing gland flange can seal the penetration part of the transmission shaft and prevent flue gas from escaping from the penetrated part of the transmission shaft of the flue. The bearing seats are installed on both sides of the flue ash hopper to support the transmission shaft and ensure the concentricity and smooth operation of the transmission shaft.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. The automatic dust cleaning of the utility model is realized by driving the dust cleaning plate on the transmission shaft to rotate through a cycloidal pinwheel speed reducer, effectively solving the problem of ash accumulation inside the flue, improving production continuity and safety. The automatic operation reduces the intensity of manual operation, and the overall installation and operation are simple.

[0016] 2. The cycloidal pinwheel speed reducer of the utility model is fixed on the speed reducer support by bolts, which is convenient to adjust the height to be parallel to the ash hopper opening of the flue, facilitating the driving of the transmission shaft to rotate. The combination of the bearing seat can ensure the concentricity and running stability of the transmission shaft.

[0017] 3. The flange B of the sealing gland flange of the utility model is welded at the ash hopper opening of the flue. The flange A is connected to the flange B through connecting bolts. With the use of packing sealing materials and gaskets, it effectively prevents the escape of flue gas and improves the sealing performance of the system.

[0018] 4. The dust cleaning plate of the utility model is designed with intermittent reinforcing rib plates, which improves the strength and durability of the dust cleaning plate, avoids fracture during rotation, and ensures the dust cleaning efficiency and long-term stable operation of the equipment.
