Abstract

The utility model relates to a multifunctional power saving range with the smokeless combustion of bituminous coal, which belongs to a range used in a dining room and is characterized in that two burning chambers are designed, namely a main burning chamber and a secondary burning chamber. The combustible gas which is not sufficiently burnt in the main burning chamber runs downward along a return flue (10) by the natural pumping force of a chimney; the combustible gas which mixes with the supplementary air through a fume pore canal passes through a lower fire grate (3) and goes into the secondary burning chamber (5); finally, the combustible gas mixes with the unburned red coke dreg loosened from the main burning chamber to achieve the sufficient combustion. When used for cooking, the utility model can generate boiling water and hot water simultaneously, which is very convenient. The utility model has the characteristics of high thermal efficiency, good effect of smoke and dust removal, etc.

Description

Multi-function power saving cooker with bituminous coal smokeless combustion

The utility model belongs to the cooking stove that a kind of dining room is used.

At present, bituminous coal smokeless combustion stove and accessory, generally the mode that all adopts backfire or positive and negative burning to combine reaches smoke abatement and dust control, and has obtained obvious effects.But ubiquitous shortcoming is: the intensity of fire of top, coal seam is not enough, and is unfavorable to cooking stir-fry.The employing multiple hearth firing method that also has in the coal burner hearth down the burner hearth burning that the red coal tong of after-flame volatile matter is gone into upper coal feeding, to reach the purpose of the strong and smokeless combustion of firepower.But increased operation sequence, improved labour intensity.

Task of the present utility model provides a kind of multifunctional stove of the bituminous coal smokeless combustion that smoke medicining dust-removing effect is good, firepower is strong, the thermal efficiency is high, easy to operate of normal burning double grate.

Solution of the present utility model is two combustion chambers of design, i.e. main combustion chamber and secondary combustion chamber, as shown in Figure 1 and Figure 2.Now elaborate in conjunction with the accompanying drawings.This kitchen range is made up of kitchen range shell ［ 1 ］, main combustion chamber ［ 9 ］, secondary combustion chamber ［ 5 ］, upper fire-grating ［ 8 ］, lower fire grating ［ 3 ］, air inlet ［ 7 ］, shutter ［ 4 ］, active clapboard ［ 6 ］, inner bag ［ 11 ］, middle courage ［ 12 ］, outer courage ［ 13 ］, air-returen flue ［ 10 ］, water boiler ［ 15 ］, hot water circuit case ［ 16 ］, boiling water storage bin ［ 22 ］, sedimentation dirt pocket ［ 24 ］, heat-insulation layer ［ 14 ］, chimney ［ 17 ］.Main combustion chamber is made of inner bag ［ 11 ］ and middle courage ［ 12 ］.Inner bag ［ 11 ］ is respectively circulating line up and down, gangs up with 6-14 root pipe welding between up and down, and circulating line is equipped with out respectively up and down, water inlet pipe is communicated with the formation boiling water circulatory system with the middle part and the bottom of water boiler ［ 15 ］.In courage ［ 12 ］ be cylindrical shape intermediate water sleeve pipe, the bottom is welded with water inlet pipe and is communicated with hot water circuit case ［ 16 ］, circulating line etc. is put down under extension downwards of its outer wall and the inner bag, inwall extends downwards, is fixed on the kitchen range base plate.Outer courage ［ 13 ］ is the cylindrical shape intercalated water sleeve, gangs up with 4-6 root pipe and middle courage, and top is welded with outlet pipe and is communicated with the hot water circuit case.Each connecting pipe is formed one with middle courage, outer courage, hot water circuit case three, constitutes hot water cyclesystem.Leave the space between middle courage and the outer courage, constitute air-returen flue ［ 10 ］.Upper fire-grating ［ 8 ］ is divided into the promising main air inlet ［ 7 ］ that burns chamber ［ 9 ］ air feed, air inlet is divided into active clapboard ［ 6 ］, when its role is to main combustion chamber pine stove, earlier active clapboard is extracted into and gives allocation, make unburnt breeze fall into the quadrate secondary combustion chamber ［ 5 ］ that middle courage inwall bottom is built into refractory brick, mud, with being about to active clapboard involution original position, main combustion chamber and secondary combustion chamber are isolated, form two each spontaneous combustions of burner hearth.The positive design of secondary combustion chamber has the shutter ［ 4 ］ that can twitch up and down, so that regulate air quantity and get rid of slag.Water boiler is interior hollow-cylindrical, the steam chest of suitable height is reserved on top, produce the small amount of steam supply and report the device ［ 18 ］ that boils, the steam chest downside is installed boiling water output channel ［ 21 ］, its water source is by the pressure feed of hot water circuit case by running water, and the inflow size keeps blast of whistle to be as the criterion with the newspaper that is installed in the water boiler top device ［ 18 ］ that boils.Hot water circuit case ［ 16 ］ is interior circle, outer oval intercalated water sleeve.Inner cylinder double as flue is connected with chimney ［ 17 ］.The top side is equipped with the hot water delivery pipe road, by tap water pressure output hot water.Establish a sedimentation dirt pocket ［ 24 ］ below the water boiler, boiling water storage bin, hot water circuit case, gravity inertial sedimentation dust-cleaning principle is adopted in this chamber, and promptly the circulation expansion cross section makes the grit natural subsidence in the flue gas.And can enlarge heat exchange area, and prolong heat-exchange time, fume afterheat is fully used.

The utility model realizes that the scheme of bituminous coal smokeless combustion is the not clean-burning combustible gas of main combustion chamber, natural draft by chimney, under air-returen flue ［ 10 ］, pass through smoke hole road ［ 2 ］ with additional air, pass lower fire grating ［ 3 ］ and enter secondary combustion chamber ［ 5 ］, mix with the eased off unburnt red breeze of main combustion chamber, make it completing combustion.A grit part of being taken out of by the main chamber flue gas sinks in air-returen flue or sinks for red burnt obstruct of secondary combustion chamber; A part is along with flue gas sinks naturally through floss hole ［ 25 ］ the bigger sedimentation dirt pocket ［ 24 ］ in cross section that circulates.

The utility model is equipped with water meter ［ 26 ］ in total water inlet place, is equipped with thermometer ［ 19 ］ on hot water delivery pipe road ［ 20 ］, can make temperature adjustable, and flow is controlled to be counted, and can supply shower.

The utility model can be made series of products with different demands according to user number.

The utility model can produce boiling water, hot water, and realize the bituminous coal smokeless combustion through on probation in the cooking, smoke medicining dust-removing effect is good, and firepower is strong, and thermal efficiency height is operated also very convenient.
