Abstract

The utility model relates to a high efficient coal-saving hot-air stove which has the advantages of high thermal efficiency, simple installation method, small volume, light weight, low cost and strong practicability. The utility model is provided with a stove body, an ash chamber and a grate. The lower part of the side wall of the stove body is also respectively welded with a fire blowing wind pipe and a heat blowing wind pipe from bottom to top, the fire blowing wind pipe is communicated with a hearth, and the heat blowing wind pipe is communicated with an inner cavity of the stove body. The other side of the side wall outside the stove body opposite to the heat blowing wind pipe is welded with a hot wind outlet, and the inner cavity of the stove body is welded with two groups of half spiral type clamping belts which have opposite positions. Both ends of each group of clamping belt are respectively positioned on the positions approaching an opening of the heat blowing wind pipe and the hot wind outlet corresponding to the opening of the heat blowing wind pipe.

Description

The high-efficient coal-saving hot-blast stove

The utility model relates to a kind of high-efficient coal-saving hot-blast stove.

Existing coal stove for heating mainly is made of body of heater, water jacket, grey chamber, add the coal combustion in the body of heater inner combustion chamber after, with the water jacket heating, again through outlet pipe to external radiator.The problem of its existence is: 1, and the installation method complexity must externally be organized radiators more; Heat transfer is slow, the thermal efficiency is low, earlier with the water jacket heating, hot water in the water jacket is delivered in the radiator behind the coal combustion again; 3, owing to water jacket is set in body of heater and water jacket will be heated, therefore, the body of heater volume is big, Heavy Weight, cost are higher relatively.

The purpose of this utility model is to provide a kind of thermal efficiency height, installation method is simple and volume is little, in light weight, high-efficient coal-saving hot-blast stove that cost is low, practical.

The utility model is achieved in that it has a body of heater, bell is arranged on body of heater, outlet flue, fire door, the ashes door, the grey indoor fire grate that is fixed with in the body of heater bottom, its special character is to be welded with blow the fire airduct and blowing hot-air pipe from the bottom to top respectively in the sidewall of the furnace body bottom, the said airduct that blows the fire communicates with burner hearth, said blowing hot-air pipe communicates with the body of heater inner chamber, be welded with a left side that communicates with furnace sandwich on body of heater lateral wall top respectively with blowing hot-air pipe correspondence position, right hot-blast outlet, be welded with in furnace sandwich that dibit is put relatively and rightabout distributes the semi-spiral formula carry secretly, said every group of two ends of carrying secretly lay respectively near blowing hot-air pipe and the hot-blast outlet position corresponding with it.

According to above-mentioned high-efficient coal-saving hot-blast stove, said fire grate is two groups, and every group of fire grate be welded on the pole, and said pole is inserted on the sidewall of grey chamber, and its bared end is fastened on the quadrangle reel cage.

According to above-mentioned high-efficient coal-saving hot-blast stove, on said blow the fire airduct and the blowing hot-air pipe sluice gate is arranged respectively, airduct and blowing hot-air Guan Shangyu sluice gate correspondence position are separately installed with flashboard blowing the fire.

High-efficient coal-saving hot-blast stove according to above-mentioned is equipped with the outlet flue windscreen on outlet flue.

The utility model has the advantages that: spread out of for hot blast, thermal efficiency height, conduct heat fast, economize on coal; Radiator need not be installed, easily install; Simple in structure, volume is little, in light weight, cost is low; Practical, except that heating, also can cook, heat up water, extremely susceptible to user acceptance.

The drawing explanation:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an A-A cutaway view among Fig. 1;

Fig. 3 is a B-B cutaway view among Fig. 1;

Fig. 4 carries structural representation secretly.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

As shown in the figure, the utility model has a body of heater 2, above body of heater 2 sidewalls, pipe 15 is installed, on pipe 15, be fitted with bull stick 14, on bull stick 14, be set with outlet flue windscreen 16, at body of heater 2 tops bell 13 is installed, be welded with grey chamber 6 in the bottom of body of heater 2, on body of heater 2 and grey chamber 6, be separately installed with fire door 19 and ashes door 18, supreme blow the fire airduct 8 and the blowing hot-air pipe 11 of being welded with respectively under body of heater 2 lower sidewall mountains, the said airduct 8 that blows the fire communicates with the burner hearth (combustion chamber) of body of heater 2 bottoms, said blowing hot-air pipe 11 communicates with the interlayer 3 of body of heater 2, on blow the fire airduct 8 and blowing hot-air pipe 11, have blowing sluice gate 10, on blow the fire airduct 8 and blowing hot-air pipe 11 outer walls, be welded with flashboard support 9, at flashboard support 9 soil the blowing flashboard 7 corresponding with the sluice gate 10 of drying is installed, be welded with a left side that communicates with interlayer 3 on body of heater 2 lateral wall tops respectively with blowing hot-air pipe 11 correspondence positions, right hot-blast outlet 12,1, a said left side, right hot-blast outlet 12,1 lays respectively at the central axis both sides of body of heater 2, half (week) spiral that is welded with two groups of rightabouts distributions in interlayer 3 carries 17 secretly, carry 17 secretly and constitute for said every group by 3-5, each carries 17 two ends secretly respectively near a warm-air pipe 11 and a left side corresponding with it, right hot-blast outlet 12,1, sidewall in grey chamber 6 is fitted with group fire grate 4, every group of fire grate 4 is welded on the pole 4, said pole 4 is inserted on 6 sidewalls of grey chamber, its bared end is fastened on the quadrangle reel cage 5, and a rocking handle 5 is arranged on the said reel cage 5.

When mounted, earlier body of heater 2, stove tube, hair-dryer, air-out pipeline are installed, said hair-dryer is connected on the mouth of pipe of blow the fire airduct 8 and blowing hot-air pipe 11 by threeway.After stove fire is lighted, earlier the flashboard 7 on the airduct 8 that blows the fire is opened, stove fire is blown prosperous with hair-dryer; Then, airduct 8 upper flashboards that blow the fire are shut again, opened blowing hot-air pipe 11 upper flashboards again, wind is delivered in the interlayer 3, become hot blast after carrying 17 secretly through two groups, send through left and right hot-blast outlet 12,1 respectively, hot blast can deliver to that each is indoor by the discharge duct of installing.When keeping temperature as need, hair-dryer can shut down, and shuts windscreen 16 on the outlet flue 15.When clearing the ashes from a stove, rocking handle 5 can be shaken, then fire grate 4 upsets, ashes can be turned down in the ash entrance chamber 6, clean out then.
