Problems solved by technology

[0007] The technical problem to be solved in the present invention is that after the existing annealing furnace is closed after use, foreign objects (such as mosquitoes) may enter the smoke exhaust pipe of the annealing furnace, causing certain blockage in the smoke exhaust pipe, affecting the normal operation of the annealing furnace. Smoke exhaust; foreign matter may also enter the annealing furnace through the smoke exhaust pipe of the annealing furnace, and cause certain damage to the interior of the annealing furnace;

specific Embodiment approach

[0044] As a specific embodiment of the present invention, the folding assembly 4 includes:

[0045] Bend the tube 41,

[0046] One end of the bending pipe 41 is fixedly connected to the exhaust pipe 3, and the other end is fixedly connected to the furnace body 1; a section of the bending pipe 41 is sleeved in a section, and the wall of the bending pipe 41 is 15° from the axis. Included angle; the inner wall of one section of the bending tube 41 is connected with the outer wall of the adjacent section through high temperature resistant nylon;

[0047] recovery tank 42,

[0048] The top of the furnace body 1 is provided with a recovery groove 42; the side of the smoke exhaust pipe 3 away from the furnace body 1 is fitted with the side of the recovery groove 42 away from the smoke exhaust pipe 3;

[0049] tie rod 43,

[0050] The pull rod 43 is connected with the inner wall of the bending tube 41, and the pull rod 43 is made of memory metal;

[0051] After inspecting the inside...

Embodiment approach

[0070] As a specific embodiment of the present invention, the furnace body 1 and the lifting platform 5 are fixedly connected by bolts;

[0071] Since the furnace body 1 and the lifting platform 5 are fixedly connected by bolts, it is convenient for the staff to connect the lifting platform 5 with the furnace body 1. When the lifting platform 5 needs to be maintained, the staff can separate the lifting platform 5 from the furnace body 1, so that the When the staff performs maintenance on the lifting platform 5, the annealing furnace can still be annealed.

[0072] The specific workflow is as follows:

[0073] When the annealing furnace needs to be turned on, the staff inspects the inside of the furnace body 1 and closes the furnace door 2, ignites the gas in the annealing furnace, and the gas burns inside the furnace body 1. At this time, the exhaust pipe 3 is in a folded state , when the internal temperature of the furnace body 1 rises, the pull rod 43 made of memory metal i...

Abstract

The invention belongs to the technical field of annealing furnaces, and particularly relates to a large table type gas low-temperature annealing furnace. Comprising a furnace body, a furnace door, a smoke exhaust pipeline and a folding assembly, the furnace door is installed on the furnace body, the smoke exhaust pipeline is installed at the top of the furnace body, and the smoke exhaust pipeline communicates with the interior of the furnace body; one end of the folding assembly is fixedly connected with the smoke exhaust pipeline, the other end of the folding assembly is fixedly connected with the top of the furnace body, and the folding assembly is used for folding and recycling the smoke exhaust pipeline; the surface temperature of the pull rod is decreased along with the decrease of the temperature, at the moment, due to the decrease of the temperature, the pull rod resets and returns, the pull rod drives the bent pipe to bend, the bent pipe drives the fixedly connected smoke exhaust pipeline to be folded while bending, the smoke exhaust pipeline is folded into the recovery tank to be recovered, and the smoke exhaust pipeline is protected; and moreover, when the annealing furnace is not used, foreign matters (such as insects) are prevented from entering the furnace body through the smoke exhaust pipeline to cause certain damage to the interior of the furnace body, and the smoke exhaust pipeline is prevented from being blocked to a certain extent to influence normal smoke exhaust of the annealing furnace.

Description

technical field [0001] The invention belongs to the technical field of annealing furnaces, in particular to a large-scale desktop gas-fired low-temperature annealing furnace. Background technique [0002] Annealing furnace is one of the heat treatment equipment in the machinery industry. Its purpose is to soften the materials or workpieces that have been cast, forged, welded or machined, reduce hardness, improve plasticity and toughness, homogenize chemical composition, and remove residues. stress, or obtain the expected physical properties; [0003] It is a metal heat treatment process in which metal parts are slowly heated to a certain temperature in different heating furnaces, kept for a period of time, and then cooled at a suitable speed (usually natural cooling, sometimes controlled speed cooling); [0004] The desktop annealing furnace is an energy-saving periodic operation furnace. It adopts a full-fiber hearth structure and an ultra-energy-saving structure, and save...
