Multigroup electric heating piece mounting groove, the peace of the clipping room away from more than bottom on electric heating piece mounting groove top are symmetrically arranged with the body of heater of both sides
Fill spacing；It is provided with multigroup combustion chamber to connect therewith on the lateral surface of body of heater, the bottom of body of heater is provided with base, in base
Cutting agency is provided with the middle part of the lower end of body of heater.
Preferably, the aperture of one-level elastic buffer net is more than two level elastic buffer net.
Preferably, the front of observation window is provided with thermometer.
Preferably, the level height of feed pipe is higher than the height of feed hopper bottom surface.
Preferably, feed pipe and flexible pipe and the secondary distributor being connected with flexible pipe are provided with more sets, and using flue axle as axle
It is uniformly distributed.
Relative to prior art, the beneficial effects of the utility model are：The main distributor of feed hopper bottom enables to thing
The whereabouts of material keeps uniformity, and the feed pipe and flexible pipe of feed hopper both sides can effectively avoid while keeping and feeding uniformity
The phenomenon of feed blocking occurs, the one-level elastic buffer net and two level elastic buffer net of body of heater enable to ore in sand form in dropping process
It is middle that complementary resilience occurs, rising expansion is carried out so as to accelerate it, electric heating piece mounting groove can carry out the heating of centralization,
Workload can be reduced in installation and later maintenance to a certain extent, observation window front can facilitate for convex safety glass
The heating state in body of heater is observed, the thermometer of front right part can conveniently observe the temperature change of lower portion of furnace body, be uniformly distributed
Temperature detection hole the temperature at different body of heater positions can be measured in time, in a word the utility model have charging uniformly,
Avoid feed blocking, installation and it is easy to maintenance, be easy to observation the advantages of.
