Abstract
The invention discloses a nitrogen protection sintering kiln, which comprises a high-temperature region and a pre-drying region, wherein the high-temperature region is connected with the pre-drying region; electric heating wires are arranged on the lateral lower part of the pre-drying region; a hot air recovery pipeline is arranged on the top of the high-temperature region and is communicated to the top of the pre-drying region. The nitrogen protection sintering kiln is simple in structure, and convenient to operate. Hot air exhausted as waste gas originally is recycled in other equipment needing to be heated through the hot air recovery pipeline, so that the heating efficiency is increased, and energy is saved.
Description
?
Technical field
The present invention relates to magnetic material manufacturing, be specifically related to a kind of nitrogen protective sintering kiln.
Background technology
In magnetic material manufacturing industry, use in a large number combustion of natural gas heating, coal combustion heating and electric-heating-wire-heating, at present in industry, no matter use which kind of combustion heating, the hot gas heat energy that heating produces is all used as waste gas discharge, and the hot gas heat energy that cannot make burning produce is recycled recycling.
Summary of the invention
The object of invention: the present invention, in order to solve the deficiencies in the prior art, provides a kind of nitrogen protective sintering kiln.
Technical scheme: a kind of nitrogen protective sintering kiln; comprise high-temperature region and prebake district; described high-temperature region is connected with prebake district, and the side lower part in described prebake district is provided with heating heating wire, and top, described high-temperature region is provided with hot gas recovery channel and is communicated to the top in prebake district.
As preferably, the number of described heating heating wire is 3 ~ 6.
Beneficial effect: a kind of nitrogen protective sintering kiln of the present invention, has feature simple in structure, easy to operate; by hot gas recovery channel; in the equipment that the hot gas recycling of being originally used as waste gas discharge need to be heated to other, improve the efficiency of heating surface, saved the energy.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
