Abstract

The utility model relates to an energy-saving oven for drying solid materials or products, which comprises an oven body, a burner, a heat exchanger, a chimney, a drying rack, a temperature controller and a fan, wherein, the fan is used to accelerate the heat release of the heat exchanger and drive heated gas into the oven body, simultaneously, the fan is used to suck gas with residual heat in an air return pipe and the gas enters the heat exchanger and is reheated. The utility model is characterized in that the oven is also provided with a rotatable heat insulation chamber which is homocentric with the oven body and is provided with a heat insulation layer casing body, an annular drying passage is formed, and thus, heating is more concentrative, more uniform and faster. The utility model has the advantages of saving energy, reducing cost, improving drying quality and increasing production efficiency. Oil gas electric coal can be optionally chosen as energy sources by the oven.

Description

A kind of energy-saving baking box

The utility model relates to a kind of baking oven in order to drying solid material or goods, particularly a kind of usable oils, gas, electricity, the coal baking oven as the energy.

The utility model is the improvement to my application number is 00202553.1, name is called " a kind of Oil fuel dry box " patent, the weak point of this patent is that utilization of space is lower in the baking oven, particularly bigger baking oven, the periphery that general oven dry object all places staff to reach, middle body is then spacious idle, thereby has wasted quite a few heat energy.

The purpose of this utility model provides a kind of can further cutting down the consumption of energy, and it is the energy that the energy-saving baking box of interior dress heat-insulating room, this baking oven can be chosen oil, gas, electricity, coal wantonly.

The utility model is so to realize: a kind of energy-saving baking box in order to drying solid material or goods includes the casing, burner, heat exchanger, chimney, oven dry frame, temperature controller of heat-insulation layer and one in order to accelerate the heat exchanger heat release and to drive and send heated gas to enter casing, aspirate again simultaneously and contain the gas that has surplus heat in the muffler and reenter the blower fan that heat exchanger heats once more, be characterized in baking oven, also being equipped with a rotating heat-insulating room that thermal insulation layer housing arranged concentric with casing.

Burner can adopt oil burner, or gas burner, or the electric heating burner, or coal-fired combusting device.

Combustion chamber and heat exchanger can be loaded on the casing inner bottom part, also can be installed in the casing outer bottom.

Chimney is installed in outside the baking oven, also can be installed in the muffler.

The branch hot cell of a ring-type is equipped with in the bottom of drying channel, and the last plane in branch hot cell has the hot hole that send of star cloth.

The bottom of heat-insulating room has more than one steam vent.

Owing to installed heat-insulating room, form a ring-type drying channel in the baking oven casing, make the baking oven heating concentrated more, even, also improved programming rate, but so the utility model not only energy savings, reduce cost, improve dries quantity, also can enhance productivity.

Now be described further with following embodiment and accompanying drawing thereof.

Fig. 1 looks schematic diagram for the local vertical profile of baking oven.

Fig. 2 is the A-A cross-sectional schematic.

As shown in Figure 1, 2, baking oven comprises: have the casing 1 of heat-insulation layer, the combustion chamber 9 of bottom half burner 13 and heat exchanger 10 to be housed, to be loaded on casing outer blower fan 15 and muffler 2, to be loaded in the muffler and to stretch out chimney 3 and the oven dry frame 6 and the temperature controller at muffler top, a rotating heat-insulating room 4 that thermal insulation layer housing arranged concentric with casing also is housed in the baking oven of heat-insulation layer is arranged.So form a ring-type drying channel 5 around in baking oven, what the branch hot cell 8 that a ring-type is housed in the bottom of drying channel, the last plane in branch hot cell 8 had star cloth send hot hole 7.The bottom of heat-insulating room 4 has two steam vents, outside the straight-through baking oven, with plan safety.Oven dry frame 6 just is installed on the outer wall of heat-insulating room 4.Heat exchanger 10 is for by 14 diameters being the tubular surface formula heat exchanger that the radiating tube 11 of φ 3cm Boulez is formed, the flue 14 of drawing from heat exchanger 10 is connected with chimney 3, when the high-temperature gas that burning produces is flowed through radiating tube 11, under the blowing hard of blower fan 15, the radiating tube 11 and take away a large amount of heats from the radiating tube surface and obtain heating thereby a large amount of ambient atmos are flowed through, gas after the heating drives to send down at wind-force and enters branch hot cell 8 by pipeline, again by sending hot hole 7 input drying channels 5, dry object, the gas of having lowered the temperature in the casing then heats from the radiating tube 11 that fans entrance 12 blows to heat exchanger 10 once more at the suction lower edge of same blower fan 15 muffler 2, and so circulation endlessly.Chimney 3 is installed in the muffler 2 and stretches out the muffler top.When gas temperature in the casing reached the temperature of requirement control, temperature controller work made burner 13 burn-outs, and blower fan 15 then works on; When temperature in the casing was lower than the requirement temperature, temperature controller work made burner 13 ignition again, and gas heating in the casing to the requirement temperature, is continued so repeatedly until finishing drying work.
