Abstract
The invention relates to a novel transverse hot air circulation device, which is applied to heat treatment equipment which heats workpieces by transverse circulating hot air and of which the hearth has a certain amount of corrosive gas in a temperature range of convection heating. The novel transverse hot air circulation device comprises an upper hearth channel, a lower hearth channel, and a left hearth air duct and a right hearth air duct which are positioned on two sides. The upper part of the left hearth air duct is connected with an air inlet of a circulating fan; a fresh air supply port and a hearth exhaust gas outlet are formed on the left side of the left hearth air duct; and a heating element is arranged inside the upper hearth channel. The novel transverse hot air circulation device makes the hot air circularly and transversely pass through the workpieces, avoids the influence of a supporting bracket and a supporting plate on the uniformity of the hot air circulation because the hot air circularly passes through the workpieces vertically, and effectively solves the problems of uniformity of hot air circulation and heating uniformity simultaneously. Therefore, the hot air passes through the workpieces more uniformly.
Description
Technical field:
The present invention relates to a kind of novel transverse hot air circulation, be applicable to the TR of convective heating, utilize hot air circulation workpiece to be carried out having in heating of traverse cycle hot blast and the burner hearth HTFX of certain corrosive gases.
Background technology:
In middle low-temperature heat treatment equipment, utilize hot air circulation quite general to the application that workpiece heats.In the prior art; The wind direction of hot air circulation all is from bottom to top or from top to bottom; No matter be from bottom to top or from top to bottom; Because supporting workpiece all needs supporting bracket and supports supporting plate etc., supporting bracket affects to hot air circulation with the support supporting plate, but also has caused the homogeneity of hot air circulation and the homogeneity question of heating.
Summary of the invention:
In order to solve the problems of the technologies described above, the invention provides a kind of novel transverse hot air circulation.
The technical solution adopted for the present invention to solve the technical problems is: a kind of novel transverse hot air circulation comprises the upper furnace passage; Lower furnace portion passage and the burner hearth left air path, the burner hearth right air path that are positioned at both sides; Said burner hearth left air path top links to each other with the blast inlet of recirculation blower; Said burner hearth left air path left side is provided with additional mouthful and the relief outlet of burner hearth waste gas of fresh air, is provided with heating unit in the said upper furnace passage.
Further: said burner hearth left air path is provided with two left hot air circulation air deflectors at least.
Further: said burner hearth right air path is provided with two right hot air circulation air deflectors at least.
Further: be provided with the hot air circulation air deflector in the said upper furnace passage.
Further: said left hot air circulation air deflector, right hot air circulation air deflector or last hot air circulation air deflector are arc.
Further: be provided with a dividing plate between the additional mouth of said fresh air and the relief outlet of burner hearth waste gas.
Further: said dividing plate is an arc.
The present invention utilizes hot air circulation laterally to pass through workpiece; Avoided since the circulation of hot blast be during vertically through workpiece supporting bracket with support supporting plate to the inhomogeneity influence of hot air circulation; Simultaneously effectively solved the homogeneity of hot air circulation and the homogeneity question of heating, it is more even to make hot blast pass through workpiece.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Accompanying drawing is a structure iron of the present invention.
