Description
Technical Field
The utility model relates to a metallurgical and chemical industry oxidation roasting electric furnace, in particular to a blast type oxidation roasting muffle furnace.
Background
Oxidizing roasting is a common material treatment process in the metallurgical and chemical processes, the oxidizing roasting is a roasting method for converting all or part of sulfides in materials into oxides, and sometimes, the oxidizing roasting is also carried out in order to volatilize impurities such as arsenic, antimony and the like in the materials.
The existing oxidation roasting is basically carried out in a rotary kiln and a muffle furnace. When the rotary kiln is used as oxidation equipment, the rotary body is easy to damage and high in maintenance cost, and the rotary body is not easy to clean when the rotary body is used for replacing materials for oxidation roasting. And traditional muffle furnace mainly divide into furnace body heat preservation district and temperature control system two parts, utilizes the temperature that temperature control system set for to carry out the calcination, and in current muffle furnace oxidation roasting system, the furnace body air is not enough, and oxidizing atmosphere is not enough, and the oxygen level is low, leads to material oxidation calcination insufficient, appears the low scheduling problem of oxidation degree effect easily. Therefore, it is necessary to design an oxidizing roasting muffle furnace with good oxidizing effect, high roasting efficiency, simple device and low cost.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a blast type oxidizing roasting muffle furnace.
In order to realize the purpose, the utility model discloses a technical scheme as follows:
a blast type muffle furnace for oxidizing and roasting comprises a furnace body, wherein a furnace chamber is designed in the furnace body, the front end of the furnace chamber is connected with a furnace door, the rear part of the furnace body is fixedly connected with an air inlet pipe, the air inlet pipe is connected to an air blower, the air inlet pipe extends into the furnace chamber, a burning pot is arranged on the bottom surface of the furnace chamber, and the burning pot is placed in a groove.
Furthermore, a thermocouple is arranged at the rear part of the furnace body, and an air inlet pipe is arranged at the rear part of the furnace body.
Further, the burning pot is placed in the middle of the bottom of the hearth.
Further, an exhaust port is designed above the furnace body and used for exhausting gas generated in the furnace body.
Furthermore, the air inlet pipe is a hollow pipe, and an air regulating valve is arranged on the air inlet pipe to regulate the size of air flow.
The utility model has the advantages that: the material is in the utility model discloses an among the muffle furnace oxidation calcination process, oxidizing atmosphere is sufficient, and the oxygen level is high, and the oxidation is effectual, and the calcination is efficient, and the device is simple, with low costs.
