Vertical continuous tempering furnace

Abstract

The invention discloses a vertical continuous tempering furnace which comprises a furnace body, wherein a heating zone and a cooling zone are arranged in the furnace body; charging and discharging ports are formed between the heating zone and the cooling zone; an air supply channel is formed in the inner side wall of the heating zone; heating pipes, a circulating fan and filters are arranged on the furnace body; a drive sprocket and a tensioner sprocket are arranged in the furnace body; the drive sprocket is connected with a drive motor; a circulating chain is connected between the drive sprocket and the tensioner sprocket; hanging baskets are connected onto the circulating chain; an air conditioning refrigeration unit is arranged at the top of the furnace body and communicated with a cooling air inlet; and a cooling exhaust fan is arranged on the cooling zone. The vertical continuous tempering furnace is energy-saving; the temperature uniformity and stability are good with adoption of an upper feeding and lower returning type air supply structure on the furnace body, a one-way cycle operation manner is adopted, and the equipment occupation area is reduced due to height increase; and meanwhile, an air conditioning is adopted to cool a workpiece, the workpiece temperature is reduced to be lower than 40 DEG C during workpiece discharging, and the workpiece temperature during workpiece taking is reduced.

Description

technical field [0001] The invention relates to the field of tempering equipment, in particular to a vertical continuous tempering furnace. Background technique [0002] After the assembly of the lamp, in order to eliminate the internal stress generated during assembly, the continuous tempering furnace is generally used for stress relief treatment at present. The entrance and exit closed door is designed, and the heating adopts air supply from both sides of the bottom and return air from the top. This type of tempering furnace has a low capacity, and after the workpiece is taken out after tempering, the temperature of the workpiece is high, so it cannot directly enter the next process, and must wait. It can enter the next process after cooling. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a vertical continuous tempering furnace with simple structure, convenient operatio...
