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: [0001] The invention relates to a new type of horizontal hot air circulation device, which is suitable for the temperature range of convection heating. The heat treatment equipment utilizes the hot air circulation to heat workpieces with horizontal circulating hot air and there is certain corrosive gas in the furnace. Background technique: [0002] The use of hot air circulation to heat workpieces in medium and low temperature heat treatment equipment is quite common. In the prior art, the wind direction of hot air circulation is from bottom to top or from top to bottom, no matter from bottom to top or from top to bottom, because supporting workpieces all need support brackets and support pallets, etc., support brackets and support brackets The plate has a certain influence on the hot air circulation, and also causes the uniformity of the hot air circulation and the uniformity of heating. Invention content: [0003] In order to solve the above technical p...
