Abstract

A kind of energy-saving tray for stoves is the key energy-conservation parts on all kinds of cooking stoves.This energy-conservation pallet is owing to adding the diaphragm that has the gas outlet more than one deck on the pallet, its each other for be staggered, camber line shape is arranged or the annular concentric arrangement, this just forces thermal current repeatedly circuitous between pallet and heated object, carry out fully after the heat exchange, discharge the gas outlet from the outermost layer diaphragm again.This energy-conservation pallet is applicable to all kinds cooking stove, industry pot coal or heating boiler etc.

Description

Energy-saving tray for stoves

The present invention is the energy-conservation parts of a kind of cooking stove, particularly is applicable to a kind of key energy-conservation parts of various types of Civil energy-saving cooking stoves, Industrial Boiler, heating boiler, blast furnace or coke oven.

Existing coal stove is that a plane pallet is arranged at its top, and has added the rib of some bendings on dish, as the Energy-saving coal stove that Hefei fuel corporation etc. produces, usefulness be exactly this form pallet.But because short in the bottom run of heated object by the thermal current on this pallet, contact area is little, and the viscous flow time is short, and heat has scattered and disappeared soon.So the flow direction, flow velocity and the flow of thermal current are uncontrollable at all, so still have a large amount of heat energy to be underutilized.

Task of the present invention provides a kind of cooking stove novel energy-conserving pallet, it be by try to get to the heart of a matter and curved diaphragm constitute.It is characterized in that on the diaphragm 2 or leave gas outlet 3 therebetween.The arrangement of diaphragm 2 is, along trying to get to the heart of a matter 1 radially for one or more layers; Diaphragm 2 can be on chassis 1 and is staggered or arrangement of camber line shape or annular concentric arrangement; There are adjustable ring 4 or adjustment sheet 4 to be regulated on the gas outlet 3 of outermost diaphragm 2.Compared with prior art, it is repeatedly circuitous between the pallet and the bottom of a pan that diaphragm 2 on this novel energy-conserving pallet, gas outlet 3 and adjusting ring plate 4 have the thermal current of forcing, make the stroke lengthening of thermal current, so just increased the contact area and the holdup time in the thermal current and the bottom of a pan.Thereby make the flow direction, flow and the flow velocity of thermal current obtain effective control, and the heat waste reduction that radiation, convection current and conduction are caused, the thermal efficiency significantly improves (can save energy more than 58 percent).

Solution of the present invention can further be illustrated with following accompanying drawing:

Fig. 1 is a holding tray surface schematic diagram of the present invention.

Fig. 2 is the schematic diagram of the enforcement of pallet of the present invention on coal stove.

The schematic diagram that Fig. 3 implements on the flat aluminum pot of taper type for pallet of the present invention.

The schematic diagram that Fig. 4 implements on farmers''s kitchen range for pallet of the present invention.

Fig. 5 is the schematic diagram of concentric ring type energy-saving tray.

Among above-mentioned 1,2,3,4,5 each figure 1 are trying to get to the heart of a matter of pallet, the 2nd, and diaphragm, the 3rd, gas outlet, the 4th, adjustable ring, sheet.

Exemplary embodiments below in conjunction with accompanying drawing and all kinds cooking stove is further described the present invention:

The diaphragm arrangement architecture of accompanying drawing 1,2 is basic identical, so be that example is illustrated with Fig. 2.

Accompanying drawing 2 is the present invention's exemplary embodiments on coal stove.The thermal current that comes out during briquette fuel, the deflector 2 through trying to get to the heart of a matter on 1 is divided into several strands, and the total length of per share air-flow distance can be 150～300 centimetres, also can be longer.Carry out after the heat exchange in the per share air-flow and the bottom of a pan, is discharged by gas outlet 3.Handle on the discharging available adjustment ring 4 of capacity is further regulated.The total length of per share hot gas flow process only is 6～7 centimetres on commercially available " coal-saving stove " pallet." use the eared pot cooking on the coal-saving stove, eared pot contacts preferably the place and only is middle part, the bottom of a pan (area is about 154 square centimeters) with thermal current commercially available.The flow velocity of thermal current and flow are all uncontrollable, and thermal current is very fast to be scattered and disappeared, so efficient is very low.The novel energy-conserving pallet can force thermal current to contact with at the bottom of the whole cooker.Cast iron eared pot (31 centimetres of bores) with minimum calculates the contact area in the thermal current and the bottom of a pan:

S=2 π RH=1223 square centimeter

And thermal current is much longer at the bottom of a pan viscous flow time ratio commercially available " coal-saving stove ".So heat energy that this energy-conservation pallet has discharged when having utilized fuel combustion fully.

Prove with commercially available " coal-saving stove " and the coal stove contrast test that this energy-conservation pallet is housed: energy-saving tray can save energy more than 58.33%.Test is undertaken by laxative remedy, and two kinds of different coal stoves of pallet are respectively put into one kilogram of briquette, use the homotype eared pot, respectively put into 1.5 kilograms of cold water, result such as following table at every turn:

General domestic briquet stove, if add one as shown in Figure 1 planar shaped or ring-type the bottom of a pan shape energy-saving tray shown in Figure 2.But, as on this pallet with taper type or the flat aluminum pot of tubular, then energy-conservationly lack than eared pot.This is because aluminum pot top fails to wrap within the energy-saving tray.For energy-conservation, a taper type or tubular pallet can be added in addition, as shown in Figure 3 above the shape pallet of the ring-type the bottom of a pan.During use, earlier taper type or tubular pallet are placed on the middle top of the bottom of a pan shape pallet 1, the aluminum pot of respective model is being put into wherein, can block the hole of porous thermal current in the bonding part of two pallets with plant ash.

" fuel saving stove " that farmers' uses can be cast an energy-saving tray simultaneously when the casting cauldron.As accompanying drawing 4, this has very big realistic meaning to alleviating rural area fuel crunch contradiction.

Industrial Boiler and boiler for warming rooms also can add the spill energy-saving tray.But oval tubular crouches and puts formula, should shorten length, adds heavy caliber, changes vertical type into and is placed among the pallet.Implementation method can be with reference to the accompanying drawings 3, but Fig. 2, and two discrete pallets should be made an integral body in 3.Boiler can be tubular with the top of spill pallet, and encases all parts except that the boiler lid, and heat-insulating material and shell should be wrapped in the periphery of whole pallet.

Commercially available kerosene stove, liquefied gas furnace, electric furnace or other cooking stove all can add the novel energy-conserving pallet, with energy savings.

Iron company's blast furnace or coke-oven plant's coke oven can be transformed with reference to the present invention.

Diaphragm structure on the various energy-saving tray for stoves can be as the dendroid staggered structure of Fig. 1 to Fig. 4, and the distribution of diaphragm and structure also can be by single or several spiral yarn shaped arrangements.Shown in Figure 5 then is that concentric annular is arranged, and then can open one or more gas outlet (can stamp out one or more square hole) on each ring, and the gas outlet on adjacent two rings can be staggered, and also can correspondingly arrange.All be in order to force thermal current repeatedly circuitous, to reach purpose of energy saving in a word at pot bottom.

The material of various types of energy-saving trays and method for making can be used respectively according to different situations: the refractory material compacting; The potter's clay roasting; Urib founding; Aluminium alloy casting; Various metal materials are one time punching molded.The heat-insulating material of pallet periphery can be used asbestos, mica, pearl sand etc.The then available plant ash in rural area replaces.
