Abstract

The utility model discloses a bituminous coal heating stove, mainly comprising a stove body, a water sheath arranged inside the stove body and a smoke channel. The smoke channel is divided into the horizontal smoke channel and the vertical smoke channel. A smoke gathering chamber is arranged between the horizontal smoke channel and the vertical smoke channel. The communicated water sheath is arranged between the stove shell and the horizontal smoke channel, the vertical smoke channel and the smoke gathering chamber. A smoke return pipeline is arranged between a ventilation ash storage chamber and the smoke gathering chamber. The utility model adopts the design of adding the numbers of the horizontal smoke channel and the vertical smoke channel, thereby greatly increasing the heat absorbing area of the water sheath and improving heat efficiency. The smoke return pipeline arranged between a ventilation ash storage chamber and the smoke gathering chamber is added, therefore, the hot air circulates among the hearth, the horizontal smoke channel and the smoke return pipe when the gathering cover is in close or semi-close state. The hot air further helps to combust on one hand, while on the other hand, the combusting particle in the stove gas is further combusted, thereby improving the using rate of fuel for application in north rural area in particular.

Description

The bituminous coal heating stove

Technical field

The utility model relates to a kind of stove and accessory, refers in particular to a kind of civilian bituminous coal heating stove.

Background technology

Raising along with people's living standard, the particularly continuous increase of per capita income of rural residents, the peasant that having solved has enough to eat and wear strives for a relatively comfortable life has paid attention to the quality of life of oneself gradually, solving the heating problem is northern peasant's active demand, the heating facility also develops towards the direction that stove and accessory adds heating installation from fire pot, wall with flues, heated kang gradually, various stove and accessorys are emerging as the spring bamboo behind the elephanta thereupon also, yet existing stove and accessory mostly is anthracite or the big tiny fragments of stone, coal, etc. and designs production, special few at the stove and accessory of bituminous coal characteristic, and bituminous coal is welcome by the peasant extensively owing to it is inflammable, with low cost; Existing stove and accessory primary structure mostly is one or several water jacket greatly and absorbs heat from burner hearth, install refractory layer, the outer filling insulation layer of water jacket in the burner hearth additional, the water jacket design is also arranged around the flue, this class design jacket structure for water complexity, the general Foundry Production that adopts, the yield rate low production cost is higher, the thermal efficiency is low, contains harmful substance especially in a large number and enters the atmosphere pollution environment with dense smoke.

Summary of the invention

The utility model provides a kind of thermal absorptivity height, good management, free of contamination environment-friendly type heating stove, to overcome the deficiencies in the prior art.

The utility model is achieved in that this bituminous coal heating stove, mainly comprise body of heater, have lower intake water sleeve flue, described body of heater is divided into inner furnace and outer stove skin, between inner furnace and the outer stove skin is the water storage water jacket, the flue inner chamber is divided into two parts up and down by fire grate, and top is that lower furnace portion is the ventilation Dust Storage Room; Described flue is divided into horizontal flue and vertical flue, horizontal flue with vertically be provided with the flue gas collecting chamber between flue, be the water jacket that communicates between level, vertical flue, flue gas collecting chamber and the stove skin; Be provided with the smoke backflow pipeline between ventilation Dust Storage Room and the flue gas collecting chamber.

The utility model also has following structure:

Described vertical flue is four, and the top of four flues is the flue collecting hood, is equiped with on the trunk line of collecting hood and closes plate.

Described horizontal flue is three.

Described smoke backflow pipeline is two.

The obtained technological progress of the utility model is: increase horizontal flue and the vertically design of flue quantity owing to adopt, the endotherm area of water jacket is increased greatly, the thermal efficiency improves; Ventilate simultaneously and set up the smoke backflow pipe between Dust Storage Room and the flue gas collecting chamber, when being in, the collecting hood trunk line closes or during semi-closed state, hot gas circulates between burner hearth, horizontal flue, smoke backflow pipe, hot-air is further combustion-supporting on the one hand, a not combustion further burning in the furnace gas on the other hand improves the utilization rate of fuel.

Description of drawings

Accompanying drawing 1 is a structure cutaway view of the present utility model;

Accompanying drawing 2 is A-A structure cutaway views of the present utility model;

Wherein, 1 is return duct; 2 is bituminous coal; 3 is horizontal flue; 4 is vertical flue; 5 is the flue collecting hood; 6 is the upper water-out mouth; 7 are following water inlet; 8 ventilation Dust Storage Rooms; 9 flue gas collecting chambers; 10 burner hearths.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail:

This bituminous coal heating stove as shown in Figure 1, 2, mainly comprise body of heater, have intake-outlet water sleeve flue, body of heater is divided into inner furnace and outer stove skin, between inner furnace and the outer stove skin is the water storage water jacket, the flue inner chamber is divided into two parts up and down by fire grate, top is that lower furnace portion is the ventilation Dust Storage Room, and the ventilation Dust Storage Room is equipped with fire door and is convenient to bank up a fire; The fire door place is provided with three flues and is divided into the flue gas collecting chamber that horizontal flue leads to rear side, and the top of flue gas collecting chamber communicates with four vertical flues, horizontal flue, vertically is the water jacket that communicates between flue, flue gas collecting chamber and the stove skin; Ventilation Dust Storage Room below be provided with the flue gas collecting chamber between the smoke backflow pipeline that communicates, when the plate of flue collector is in sealing or when semiclosed, hot gas circulates between burner hearth, horizontal flue, smoke backflow pipe, hot-air is further combustion-supporting on the one hand, a not combustion further burning in the furnace gas on the other hand improves the utilization rate of fuel.
