Description

Technical Field

[0001] The utility model relates to the technical field of lead-zinc pyrometallurgy, in particular to an auxiliary disassembly and assembly tool for a sintering machine ignition furnace. Background Technique

[0002] The sintering machine ignition furnace is one of the important equipment for smelting lead and zinc by the ISP process. Its main function is to use producer gas as fuel to ignite the sintering machine ignition material layer. Its structure is a cuboid made of high-strength steel plate except for the bottom, lined with heat-insulating refractory materials, and there are two rows of air and gas ring pipes and ignition burners at the top. During normal production, since the ignition temperature of the ignition furnace is as high as about 1000 degrees Celsius, lead-zinc sulfide ore reacts with oxygen at high temperature to produce sulfur dioxide flue gas. The high-temperature and high-acid flue gas will cause burning and corrosion to the furnace body and accessories of the ignition furnace. Therefore, the entire ignition furnace needs to be replaced at regular intervals. Since the top and both sides of the ignition furnace hood are a series of auxiliary process equipment and facilities such as a shuttle-type feeder and a bunker, when replacing the ignition furnace, the crane in the workshop cannot lift the huge ignition furnace and accessories out or into the hood as a whole. Therefore, employees can only disassemble the ignition furnace from the two rows of air and gas ring pipes and ignition burners at the upper part in turn through tools such as chain hoists and electric and gas welding in the narrow ignition furnace hood and then move it out of the hood, and then move the newly made replacement into the hood for assembly. Due to the large weight of the equipment and the narrow installation space, the labor intensity of employees is very high in this disassembly and installation method, and it is easy to occur extrusion accidents, with relatively large potential safety hazards. Content of the Utility Model

[0003] The purpose of the utility model is to provide an auxiliary disassembly and assembly tool for a sintering machine ignition furnace to solve the problems raised in the above background technique.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] An auxiliary disassembly and assembly tool for a sintering machine ignition furnace includes a track located between the ignition furnace and the maintenance operation plane. One end of the track is on the sintering machine trolley directly below the ignition furnace, and the other end of the track is fixedly installed on the maintenance operation plane. A track trolley for carrying the ignition furnace is slidably arranged on the track, and a traction component is fixedly arranged at one end of the track trolley, and the traction component is used to traction the reciprocating movement of the track trolley on the track.

[0006] The traction component includes a steel wire rope and a pulley block. The steel wire rope is fixedly installed at one end of the track trolley, and a pulley block adapted to the steel wire rope is fixedly arranged at one end of the maintenance operation plane far away from the ignition furnace.

[0007] Baffles for restricting the movement of the track trolley are arranged at both ends of the track.

[0008] The track includes two relatively arranged steel rails, and several connecting rods are welded between the two steel rails. The baffle is welded and installed at both ends of the two steel rails.

[0009] The track trolley is welded by two steel rails and several load-bearing wheels.

[0010] The maintenance operation plane is composed of several load-bearing brackets, and the load-bearing brackets are fixedly arranged on the lower surface at one end of the track.

[0011] The load-bearing bracket is made by welding channel steel.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0013] By building a simple track trolley and track, the present utility model breaks through the space limitation of the factory building and the cover body, realizes the overall demolition and installation of the ignition furnace and its accessories, and shortens the demolition and installation period from the previous 7 days to 2 days. It eliminates the safety hazard that employees may be squeezed when demolishing and installing accessories such as the ignition furnace air duct and gas ring pipe in the narrow space of the cover body, reduces the difficulty of demolition and installation, and alleviates the labor intensity of the staff.
