Air outlet and return device on aging furnace

Technical Field

The utility model relates to an air-out air return device on ageing furnace.

Background

The aging furnace is one of the main boiler modes of the current mechanical processing consumption, and the equipment can always present maintenance atmosphere in consumption, so that the workpiece can be ensured to have good surface accuracy after being finished, and the toughness and the rigidity of the workpiece are effectively ensured. Based on these advantages, aging ovens are currently used in social consumption, and the demand is increasing year by year. The traditional aging oven generally adopts an air guide sleeve to enter and exit air, and the air guide sleeve is generally fixed at two ends of a charging trolley of the aging oven or placed on an oven door. The circulating air in the furnace often can not form effective laminar air in the furnace, and the turbulent flow phenomenon is serious.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provide an air-out and air-returning device on an aging furnace, which can ensure that the circulating wind energy in the furnace forms effective laminar wind in the furnace and reduce the turbulent phenomenon; the air outlet of each part of the circulating air in the aging furnace corresponds to the return air, and all the circulating air passes through the furnace at equal intervals, so that the accurate temperature control of each point in the furnace is realized. And can also avoid local high temperature phenomenon during direct combustion type heating.

In order to realize the purpose, the technical scheme of the utility model a design air-out air return device on ageing furnace, including the guide plate subassembly that a plurality of groups set up side by side, every guide plate subassembly of group includes the same but the different bent plate of size of two piece at least shapes and sets up the perforated plate in the studio wind gap, and the upper end of bent plate is located the studio wind gap department of heating, and the lower extreme of bent plate is located studio wind gap department. Guide plate components are additionally arranged at the air outlet and the air return inlet of the air guide sleeve, and are designed symmetrically front and back, so that the outlet air of each part of the circulating air in the aging furnace corresponds to the return air, all the circulating air passes through the furnace at equal intervals, and the accurate temperature control of each point in the furnace is realized. Each baffle assembly may also be formed from two or more C-shaped curved plates of the same shape but of different sizes.

The further technical proposal is that a plurality of ventilation holes are arranged on the perforated plate.

The further technical proposal is that the curved plate comprises at least two transverse plates and at least two vertical plates between the transverse plates which are integrated; each group of guide plate components comprises at least one small-size bent plate close to the aging furnace body and one large-size bent plate far away from the aging furnace body.

The further technical scheme is that the mounting plate of the porous plate is fixed to the small-size curved plate in an adaptive mode, the porous plate is fixed to the mounting plate through screws, the mounting plate is evenly arranged in four corners and a middle area of the working chamber and connected with the small curved plate, and the porous plate can be flexibly mounted and dismounted.

The further technical proposal is that the guide plate components are arranged in parallel and cover the working chamber air port and the heating chamber air port; the small-size bent plate and the large-size bent plate in each group of guide plate assemblies are transversely arranged along the aging furnace body.

The utility model has the advantages and the beneficial effects that: the circulating wind energy in the furnace can be ensured to form effective laminar wind in the furnace, and the turbulent flow phenomenon is reduced; the air outlet of each part of the circulating air in the aging furnace corresponds to the return air, and all the circulating air passes through the furnace at equal intervals, so that the accurate temperature control of each point in the furnace is realized. After the device is added, although the wind resistance is increased, the device is helpful for mixing cold air and hot air, and can also avoid the local high temperature phenomenon during direct-combustion heating.
