Description

A temperature-controllable reverberatory furnace for lead smelting

technical field

The utility model relates to a smelting equipment, in particular to a temperature-controllable reverberatory furnace for lead smelting.

Background technique

At present, most temperature-controllable reverberatory furnaces for lead smelting use solid fuel as the heat source, and their furnace body structure is mainly composed of two parts: a combustion chamber and a smelting chamber with relatively independent spaces. The solid fuel in this reverberatory furnace is layered combustion, which requires workers to constantly stir the solid fuel to achieve as complete combustion as possible. This kind of reverberatory furnace has low thermal efficiency, high coal consumption and serious environmental pollution. In addition, temperature, an important parameter of smelting conditions, cannot be precisely controlled.

Contents of the invention

The utility model provides a temperature-controllable reverberatory furnace for lead smelting. The reverberatory furnace has high thermal efficiency, low coal consumption and little pollution, and can precisely control the smelting temperature. the

The technical scheme of the utility model is as follows:

A temperature-controllable reverberatory furnace for lead smelting, comprising a combustion chamber and a smelting chamber in a single space, characterized in that the combustion chamber is located on the upper part of the smelting chamber, the upper part of the combustion chamber has a flue, and the lower part is provided with A slag pit, the tail of the combustion chamber has a slag hole; the front end of the combustion chamber is sequentially connected with a pulverized coal injector, a pulverizer, a conveyor belt and a pulverizer; a temperature control device for controlling the temperature is set in the center of the upper part of the combustion chamber ; The positions of the combustion chamber, pulverized coal injector, pulverizer, conveyor belt and pulverizer are from low to high in turn. the

Because the utility model changes layered combustion into suspension combustion, the combustion is more complete, the thermal efficiency is high, and the energy consumption is low. The position of the device, pulverizer, conveyor belt and pulverizer is from low to high, which reduces power loss; in addition, the smelting temperature can be precisely controlled.

Detailed ways

Below in conjunction with specific accompanying drawing and embodiment the utility model is further described. the

A temperature-controllable reverberatory furnace for lead smelting provided by the utility model includes a combustion chamber 6 and a melting chamber 7 in a single space, the combustion chamber 6 is located on the upper part of the melting chamber 7, and the upper part of the combustion chamber 6 has The flue 8 is provided with a slag pit 9 at the bottom, and the tail of the combustion chamber 6 has a slag hole 10; the front end of the combustion chamber 6 is sequentially connected with a pulverized coal injector 5, a pulverizer 3, a conveyor belt 2 and a pulverizer 1 . A temperature control device 11 for controlling temperature is provided in the center of the upper part of the combustion chamber 6 . The positions of the combustion chamber 6, the pulverized coal injector 5, the pulverizer 3, the conveyor belt 2 and the pulverizer 1 are from low to high in sequence. the

When in use, the coal is first pulverized to below 15 mesh by the pulverizer 1, and then transported to the pulverizer 3 by the conveyor belt 2 to obtain 300 mesh coal powder. Combustion is carried out in the combustion chamber 6. Therefore, the combustion mode of this device is pulverized coal suspension combustion, the combustion is relatively complete, the thermal efficiency is high, and the pollution is small; From low to high in turn, so power consumption decreases.
