Coal plays the role of vital, conduct under normal conditions as a kind of fossil fuel in the development of the mankind
For fuel, directly to burn for main energy harvesting means, with the continuous progress of science and technology, fire coal decomposes further utilization and obtains
Substantially develop, but many middle-size and small-size coal consumption users still use more original direct combustion type, it is usually this
The equipment that fire coal takes energy is called coal furnace, and coal furnace is generally divided into combustion chamber, blast channel and for containing the medium pot of water etc., fires
The fire coal that ignites in room is burnt, large quantity of air is blasted by blast channel to improve burning degree, then cinder after fired coal combustion is residual
When being left to a certain degree, progress cleaning work, but the cinder temperature still with higher that these needs are cleared up, have certain
Utilisable energy, if not taking appropriate barrier measures that will cause damages to ambient enviroment and operator, therefore, for this
The recycling of a little waste heats will reduce the energy consumption of coal furnace.
Summary of the invention
The object of the present invention is to provide a kind of Enevgy-saving coal-fired furnaces, cannot recycle and make to solve waste heat in the prior art
At the higher problem of energy consumption.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of Enevgy-saving coal-fired furnace, including combustion chamber, blast channel and medium pot, medium pot are arranged right above combustion chamber, blast channel
The lower part of position connection combustion chamber, the rear end lower of the combustion chamber are equipped with Heat Room, and Heat Room rear portion is equipped with cinder containing box, institute
The cinder channel that Heat Room includes heat exchanging chamber He is threaded through in the heat exchanging chamber is stated, cinder one end of the channel is connected to combustion chamber, another
End connection cinder containing box, the Heat Room is interior to be laid with heat exchanger tube around cinder channel outer wall, and heat exchanger tube one end is connected to medium
Pot, the other end are connected to medium supply apparatus.
The front lower portion of the combustion chamber is equipped with scraper plate, and scraper plate is vertically arranged in bottom of combustion chamber, and scraper plate is equipped with mandril,
Mandril stretches out combustion chamber.
The mandrel ends connect hydraulic mechanism, and hydraulic mechanism includes hydraulic cylinder, and the cylinder ends connect mandril.
The cinder channel is by 180 ° of Y-direction anticlockwise of shape, and small end connection combustion chamber, and big end connection cinder is received
Receive case.
Cinder collecting pipe is equipped between the cinder channel and cinder containing box.
The cinder containing box is equipped with water mist mechanism, and water mist mechanism includes nozzle and water pump.
The beneficial effects of the present invention are:
1. the Heat Room that the present invention is arranged can accommodate the cinder for carrying a large amount of thermal energy being just discharged, cinder is logical by cinder
For remaining thermal energy by the Absorption of Medium in heat exchanger tube, heat exchanger tube send the medium being heated to medium pot when road, realizes coal
Remaining thermal energy is re-used while slag cools down, and reduces whole energy consumption.
2. the cinder of combustion chamber lower part easily can be blown into cinder channel by the scraper plate that the present invention is arranged, people is avoided
The security risk that work operation generates, has ensured the safe operation of worker.
3. the cinder channel by 180 ° of Y-direction anticlockwise of shape that the present invention is arranged can by early period be sent into cinder into
Row segmentation, then enables in the middle part of cinder that the part of easy heat radiation can not transfer heat to heat exchanger tube readily yet, increases heat exchange
Effect improves energy recovery efficiency.
4. cinder collecting pipe and water mist mechanism that the present invention is arranged can reduce flying upward for dust, working environment is protected
And personnel health.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of Enevgy-saving coal-fired furnace of the present invention.
In figure: 1. medium pots；2. combustion chamber；3. blast channel；4. cinder channel；41. Heat Room；42. heat exchanger tube；5. coal

Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
The specific embodiment of Enevgy-saving coal-fired furnace of the invention is as shown in Figure 1, a kind of Enevgy-saving coal-fired furnace, including combustion chamber 2, drum
Air duct 3 and medium pot 1, the setting of medium pot 1 is right above combustion chamber 2, the lower part of blast channel 3 connection combustion chambers 2, the burning
The rear end lower of room 2 is equipped with Heat Room 41, and 41 rear portion of Heat Room is equipped with cinder containing box 6, and the Heat Room 41 includes heat exchanging chamber
With the cinder channel 4 being threaded through in the heat exchanging chamber, 4 one end of cinder channel is connected to combustion chamber 2, and the other end is connected to cinder containing box
6, cinder channel 4 is by 180 ° of Y-direction anticlockwise of shape, and small end connection combustion chamber 2, big end connection cinder containing box 6, coal
It is equipped with cinder collecting pipe 5 between slag channel 4 and cinder containing box 6, is laid in the Heat Room 41 around 4 outer wall of cinder channel
Heat exchanger tube 42,42 one end of heat exchanger tube are connected to medium pot 1, and the other end is connected to medium supply apparatus；Cinder containing box 6 is equipped with water mist
