Description

Technical Field

[0001] The present application relates to the technical field of waste heat steam boilers, and in particular to a furnace drum for a waste heat steam boiler. Background Art

[0002] Waste heat steam boiler utilizes waste heat in flue gas discharged from heating furnace, fuel gasification device, etc. to heat water to a certain temperature to generate high-temperature steam. It is mainly composed of three parts: heat pipe soft water heater, heat pipe furnace barrel, and heat pipe economizer. The heat pipe adopts longitudinal fins and annular fins in a forked arrangement. The heat pipe transfers heat between flue gas and water to generate saturated steam. At present, in order to facilitate the lifting of heat pipe furnace barrels, ear plates are often welded on them. However, due to the excessive weight of the heat pipe furnace barrel, the ear plates are prone to fall off from the furnace barrel during the lifting process, causing the furnace barrel to fall, reducing the lifting safety of the furnace barrel and bringing a bad user experience to the user. Utility Model Content

[0003] In order to make up for the above shortcomings, the present application provides a furnace barrel for a waste heat steam boiler, which aims to improve the current problem of welding ear plates on the heat pipe furnace barrel for the convenience of lifting it. However, due to the excessive weight of the heat pipe furnace barrel, the ear plates are prone to fall off from the furnace barrel during the lifting of the furnace barrel, causing the furnace barrel to fall, thereby reducing the safety of lifting the furnace barrel.

[0006] The guide plate is slidably inserted in the support block, the slider is fixed on the outer wall of the guide plate, and the slider is also slidably arranged on the support block. The threaded rod thread passes through the slider, and the end of the threaded rod is threaded on the support block.

[0007] In one embodiment of the present application, a plurality of ear plates are provided on one side of the furnace body, and the plurality of ear plates are distributed in a triangular structure.

[0008] In one embodiment of the present application, it further includes a reinforcing rib, one side of which is fixed to the outer wall of the furnace body, and one side of which is fixed to the outer wall of the ear plate.

[0009] In one embodiment of the present application, a plurality of thread grooves are linearly and equidistantly provided on the support block, and the thread grooves are arranged in two rows.

[0010] In one embodiment of the present application, a special-shaped hole is opened on the support block, the guide plate is slidably inserted in the special-shaped hole, and the sliding block is also slidably set on the special-shaped hole.

[0011] In one embodiment of the present application, a polygonal groove is provided on the threaded rod, and the polygonal groove is a hexagonal groove.

[0012] The beneficial effects of the present application are as follows: a furnace drum for a waste heat steam boiler obtained by the present application through the above-mentioned design, when in use, multiple hooks are respectively installed on multiple ear plates, and then the furnace drum body is lifted by a lifting device, and multiple ear plates disperse the weight of the furnace drum body to ensure that the weight of the furnace drum body will not be concentrated on one ear plate, so that the ear plate is not easy to fall off, and when one ear plate falls off, the other ear plates can also play a lifting role to ensure that the furnace drum body will not fall off. In addition, reinforcing ribs are installed between the ear plates and the furnace drum body to make the ear plates more firmly fixed on the furnace drum body. When the furnace drum body needs to be installed, the base is moved according to the structure of the installation platform, and the distance between the base and the support block is adjusted so that the lower surface of the base is close to the installation platform. The upper surfaces of the drum are fitted together, and after adjustment, hold the base and rotate the threaded rod to make the end of the threaded rod enter the threaded groove to fix the base. The furnace body can be lowered to install it. The waste heat steam boiler uses a furnace with multiple ear plates installed thereon. The multiple ear plates disperse the weight of the drum body to ensure that the weight of the drum body will not be concentrated on one ear plate, so that the ear plate is not easy to fall off. When one ear plate falls off, the other ear plates can also play a lifting role to ensure that the drum body will not fall, thereby improving the lifting safety of the drum. In addition, the distance between the base and the support block can be adjusted according to the structure of the mounting platform, which is convenient for installing and fixing the drum body. It is more applicable and brings better use experience to users. BRIEF DESCRIPTION OF THE DRAWINGS
