Problems solved by technology
[0002] In the prior art, centrifugal circulation fans are used in the hot air circulation tempering furnaces for heat treatment of metals, and the wind direction is from top to bottom. After such circulation, the gas discharged from the centrifugal circulation fans still has a relatively high temperature. Leading to a serious shortage of temperature internal circulation, wasting energy and reducing economic benefits

The invention relates to a novel hot-air internal circulation tempering furnace which comprises a charging table, a furnace body, a discharging table, and a conveyor belt located inside the tempering furnace; the charging table and the discharging table are located at two sides of the furnace body respectively; the furnace body comprises a furnace shell; an internal furnace is disposed inside the furnace shell; the internal furnace is divided into two layers with a air-guiding channel in the middle; a heating element is disposed in the air-guiding channel; a fan is disposed above the internal furnace; an air outlet of the fan is disposed inside the internal furnace; an air inlet of the fan is connected to the air-guiding channel; the air-guiding channel is communicated with the inner of the internal furnace at the bottom of the internal furnace. With the adoption of a structure which can realize hot-air internal circulation, the used hot air is reheated by the heating element, and the heated air is blown again to a workpiece surface so as to realize the three-time utilization of hot air; through circulation and repetition, residual temperature can be used for many times.
Description
technical field [0001] The invention relates to a low-temperature tempering furnace for metal heat treatment, in particular to a novel hot air internal circulation tempering furnace. Background technique [0002] In the prior art, centrifugal circulation fans are used in the hot air circulation tempering furnaces for heat treatment of metals, and the wind direction is from top to bottom. After such circulation, the gas discharged from the centrifugal circulation fans still has a relatively high temperature. As a result, the temperature internal circulation is seriously insufficient, which wastes energy and reduces economic benefits. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of hot air internal circulation tempering furnace that can change the serious shortage of internal circulation. [0004] The technical solution adopted by the present invention to solve its technical problems is: a new type o...
