Abstract
The utility model relates to a novel transverse hot blast circulating device, adapted to the convection heating temperature range. The novel transverse hot blast circulating device can performing the transverse circulating hot blast heating on the workpiece by using the hot blast circulating, and is a heat treatment device with the gas with the corrosivity in the hearth. The novel transverse hot blast circulating device comprises a hearth upper channel, a hearth lower channel, and a hearth left air channel and a hearth right air channel located at both sides, the upper portion of the hearth left wind channel is connected with an air inlet of a circulating fan, the left side of the hearth left air channel is provided with a fresh air supplement opening and a hearth exhaust gas outlet, and a heating element is arranged in the hearth upper channel. According to the utility model, the hot blast is used to transversely pass through the workpiece in a circulating way, the influence of the support and the support plate on the hot blast circulating uniformity when the hot blast vertically passes through the workpiece in the circulating way is prevented, at the same time, the hot blast circulating uniformity and the heating uniformity are good, thus the hot blast passes through the workpiece more uniformly.
Description
Technical field:
The utility model relates to a kind of novel transverse hot air circulation, is applicable to the temperature range of convective heating, utilizes hot air circulation workpiece to be carried out having in heating of traverse cycle hot blast and the burner hearth Equipment for Heating Processing 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 and support supporting plate affect to hot air circulation, but also have 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 utility model provides a kind of novel transverse hot air circulation.
The technical scheme that its technical problem that solves the utility model adopts 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, described burner hearth left air path top links to each other with the blast inlet of recirculation blower, described 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 described upper furnace passage.
Further: described burner hearth left air path is provided with two left hot air circulation air deflectors at least.
Further: described 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 described upper furnace passage.
Further: described 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 described fresh air and the relief outlet of burner hearth waste gas.
Further: described dividing plate is an arc.
The utility model utilizes hot air circulation laterally to pass through workpiece, avoided because the circulation of hot blast is a supporting bracket and support supporting plate to the inhomogeneity influence of hot air circulation during vertically by workpiece, 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.
