Abstract

The invention discloses an electric heating sintering furnace. The furnace comprises a furnace body, a circular bucket, a waste gas pumping device and an air pumping device. The furnace body is provided with a sintering cavity internally provided with an electric heating layer and a putting layer arranged at the inner bottom end of the furnace body and provided with multiple ventilation holes andmultiple hot air channels, the circular bucket is used for enabling waste gas generated by electric heating sintering of shell mold residual wax in the furnace body to be fed in from the interior of the furnace body via the hot air channels, the waste gas is continuously and circularly combusted, when the detection waste gas pressure in the furnace body is large, the waste gas pumping device is used for sucking in the waste gas in the furnace body, air is supplied through the air pumping device while the waste gas is sucked for helping waste gas combustion, when the sintering program is finished, a furnace door of the furnace body is opened, the waste gas pumping device presses the waste gas back to the hot air channels and feeds the waste gas into the furnace body to be combusted, waste gas combustion is complete, and the environment-friendly aim is achieved.

Description

technical field [0001] The invention relates to an electric heating sintering furnace, in particular to an electric heating sintering furnace which can solve the problem of incomplete combustion of a small amount of waste gas produced by sintering residual wax on shell molds, and make the waste gas burn completely so as to achieve the purpose of environmental protection. Background technique [0002] Generally, when there is some residual wax in the corners of the shell mold, the electric heat of the electric heating sintering furnace is currently used to burn the residual wax of the shell mold in the furnace at high temperature. Installing a set of waste gas treatment equipment outside the electric heating sintering furnace will increase the cost of the industry, or directly discharge air pollution, which is a problem that the industry is eager to solve. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electri...
