Description

The heating stove of fire-tube type

The utility model relates to a kind of structure of simple room heater heating stove.

Along with the raising of people's living standard, very big variation has appearred in the heating mode of family, and a kind of heating system that provides hot water to form Natural Circulation by small-sized coal stove in vogue at present promptly claims simple room heater.It has many good qualities, and warms oneself jointly as its each chamber of energy centralized operation, the Room, can improve the health condition shape of directly warming oneself with single small coal largely.This heating stove before all is water jacket or pancake coil to be housed to draw coal-fired heat in stove, because the structure problem of burner hearth and water jacket, it is not high the thermal efficiency often to occur, and the heat in fire coal and the flue gas is not fully absorbed and runs away, and causes the loss of the energy.

The purpose of this utility model is to release a kind of heating stove with novel burner hearth and flue structure, to improve the thermal efficiency, considers simultaneously extensively to adapt to several coal types commonly used, makes every effort to accomplish wide adaptability, easy to operate.

By as above design, the fire-tube type heating stove that this programme provided comprises shaft, heat-insulation layer, bell, fire grate, ash hole, smokejack, water jacket, furnace lining and intake-outlet, its concrete feature is: it also has a removably honeycomb briquette tile, compound water jacket, cover puts a chimney on the stove and make the fire draw, fire-suppressing cover, last fire sealing cover and following fire sealing cover, its compound water jacket comprises hearth water sleeve and fire tube water jacket two parts, hearth water sleeve is the long and narrow annular space that surrounds burner hearth, the fire tube water jacket is the annular space that many fire tubes are passed in a centre, its external diameter is identical with the external diameter of hearth water sleeve, the mutual UNICOM of two parts water jacket, it is a leak free airtight container, the top of water jacket picks out water pipe, the bottom taps into water pipe, its fire-suppressing cover diameter greater than the internal diameter of fire tube water jacket less than each inward flange of arranging good fire tube, removably the external diameter of honeycomb briquette tile is less than the internal diameter of fire tube water jacket, and the height of tile should be less than the lower limb of fire tube water jacket to the distance between the fire grate, and the external diameter of following fire sealing cover should be equal to or slightly less than the external diameter of tile.

Fire tube in this programme in the fire tube water jacket is obliquely installed, and its angle of inclination is the angle in vertical direction with ± 50 °.The quantity of fire tube is between 2～150.Its last fire sealing cover is made up of lid and swivel plate, the external diameter of lid is greater than the outward flange of arranging many good fire tubes, covered a circular arc slotted hole, its swivel plate is a T shape plate, bearing pin and lid by a upper end band drop handle link, swivel plate and bearing pin are in active relationship, and the transverse arm part of its swivel plate can all cover the circular arc slotted hole.Its cover that puts a chimney on the stove and make the fire draw is a circle cover that 90 ° of limits of upset are arranged suitable for reading, and its height and tile height sum are equal to or slightly less than fire tube water jacket upper surface to the distance between the fire grate, and the external diameter at its circle cover flange place is equal to or slightly less than the internal diameter of fire tube water jacket.

Adopt this programme can embody following superiority: when 1. using the pipe-line system of heating and the water jacket in the stove to be full of water, in burner hearth, coal is lighted, hearth water sleeve is directly drawn coal-fired heat, when using fire-suppressing cover, it can be blocked the suitable for reading of fire tube water jacket, its flue gas and flare must pass through fire tube, water in the fire tube water jacket can further absorb the heat in flue gas and the flare, therefore its thermal efficiency is significantly improved, add fire tube and be obliquely installed, the fire tube of inclination can obtain washing away strongly of flare, and it is abundant to absorb heat, through the test of energy-saving monitoring center, Tianjin, its thermal efficiency is up to 87.8%; 2. this programme is provided with removably coal watt, load onto this watt when burning the honeybee coal and be convenient to the honeycomb briquette location, when making meal with honeycomb briquette, add the cover that puts a chimney on the stove and make the fire draw, flare is upwards straight-through, firepower is concentrated when being convenient to the cooking use, when burning coal briquette or coal cinder, remove tile, burner hearth strengthens, firepower is more prosperous, the applicable various coal types of this stove; 3. this stove is designed to series of products, can be divided into 9 grades, can satisfy the appropriate needs of different heating areas, unlikelyly causes energy waste; 4. this programme is reasonable in design, and series specification is complete, is convenient to make in batches promote the use of.

Fig. 1, Fig. 2 are the structural representations of the heating stove of this programme fire-tube type, and Fig. 2 is the vertical view of Fig. 1.

Fig. 3, Fig. 4 are the structural representations of going up fire sealing cover, and Fig. 4 is the vertical view of Fig. 3.

Fig. 5 is to use the schematic diagram when putting a chimney on the stove and make the fire draw cover.

The embodiment of existing accompanying drawings this programme.Shaft (10) is the cylinder barrel shaped that steel plate is welded into, the furnace roof squarely, the top fire door has bell (2), there is smokejack (1) at the rear portion, ash hole (13) is arranged at the bottom, in fire grate (12) is arranged, its compound water jacket is also made with the steel plate welding, it is made of hearth water sleeve (8) and fire tube water channel (5) and communicates with one another, also have the furnace lining (19) of seat clay at the water jacket inner edge, the heat-insulation layer (11) of rock wool is arranged between water jacket and the shaft, the top of water jacket picks out water pipe (14), the bottom of water jacket taps into water pipe (9), removably honeycomb briquet stove coal watt (7) is arranged in stove, the fire tube (4) of many inclinations is arranged in the fire tube water jacket, its angle of inclination is between ± 50 °, the quantity of fire tube is decided on the size of stove, between 2～150.Coal watt when burning honeycomb briquette installs the cover (15) that puts a chimney on the stove and make the fire draw again additional when making meal with honeycomb briquette, remove coal watt when burning coal briquette or coal cinder.Cover fire-suppressing cover (3) at ordinary times, flare must approach fire tube (4), covers fire sealing cover when banking up a fire, and adds a cover down fire sealing cover (6) when banking up a fire for a long time again, can make burning velocity reduce to very slow and do not put out a fire.This programme is provided with the fire tube structure, and heating surface area strengthens, so thermal efficiency height.Fire sealing cover is made up of the bearing pin (18) of lid (20), swivel plate (17) and band drop handle on it, has covered the circular arc slotted hole, and swivel plate can all cover the circular arc slotted hole, can regulate and keep the suitable area of air vent when banking up a fire arbitrarily.
