The specific embodiment

As depicted in figs. 1 and 2, a kind of bituminous coal continuous burning water pipe hot-water boiler is made up of body of heater 22, water courage 23, heating intake-outlet, fire grate and outlet flue 1.The body of heater upper surface is half garden shape, and the body of heater upper surface is provided with the relief tube 19 that communicates with water courage upper end, can make body of heater not have the operation of pressure, and body of heater has higher security when not having the operation of pressure.The in-furnace hanging chamber 26 that is positioned at the fire grate upper end is tilting, and it is front furnace 32 and rear hearth 27 that tilting in-furnace hanging chamber is cut apart in the body of heater.The infundibulate that rear hearth is big up and small down has the exhausting effect, is beneficial to the abundant burning of coal.Front furnace communicates with the rear hearth lower end, the coal that adds in the front furnace from last stoking door 6 can only be for helping the auxilliary heat of penetrating coal-fired on the fire grate to heat like this, its fuel gas and dust be the high-temperature region of process rear hearth lower end downwards, just can enter outlet flue, thereby greatly reduce body of heater smoke evacuation dust quantity, and prolong the body of heater endotherm area, increase substantially heat utilization efficiency, the rear hearth upper end outlet flue that communicates, body of heater side and top are the water courage with adding between the layer 3.Outlet flue passes water courage upper end and communicates with the rear hearth upper end, is provided with mouth door 18 in the outlet flue, and the mouth door is by being positioned at outer handle 5 of outlet flue and guide rod 2 control unlatching sealing outlet flues, to pass in and out air capacity in the burner hearth before and after the control.

Rear hearth upper end is interval with perpendicular puts water pipe 24 and horizontal water pipe 25, perpendicular water courage intercommunication of putting water pipe and horizontal water pipe two ends and in-furnace hanging chamber both sides and upper end and corresponding position, and fire grate is by rigid grate 28 and reciprocating typely constituted from the deashing fire grate.

Describedly perpendicular put water pipe and horizontal water pipe is tilting, be beneficial to the water circulation.The described rigid grate that is positioned at the rear hearth lower end is tilting.

Described back and forth from the deashing fire grate, fire grate 29 is coupling with body of heater, the fire grate lower end laterally is provided with fire grate axial trough 33, the fire grate axial trough is enclosed within on the balance staff 30, the balance staff lower end connects the fixed axis 11 that is positioned at its lower end by fork 34, the two end axles of fixed axis is connected on the body of heater of burner hearth lower end, is positioned on the outer end fixed axis of body of heater to be connected with deashing handle 10.Shown in Figure 2 is by being provided with two fire grate axial troughs in lateral separation, fire grate lower end, and at this moment, two fire grate axial troughs are enclosed within respectively on two balance staffs, and two balance staff lower ends connect two fixed axis 11,31 that are positioned at its lower end respectively by fork.The two end axles of two fixed axis is connected on the body of heater of correspondence of burner hearth lower end, is positioned on the fixed axis 11 of the outer end of body of heater to be square shaft, is connected with the deashing handle on the square shaft.Back and forth can cooperate the preceding rigid grate that is positioned at front and back end it on and the back lower end of rigid grate 28 from the deashing fire grate, rigid grate and the utility model lower end are deashing chamber, and the body of heater of deashing chamber side is provided with shoot door 13, is beneficial to coal ash is removed deashing chamber.One wing furnace body of fire grate upper end is provided with fire door 7 and

side ort

14,9, also is used for deashing and stoking.Wing furnace door 17 is established in the body of heater upper end, is used to observe deashing.During deashing, to hold the deashing handle rocks back and forth, the deashing handle drives fixed axis 11 makes it come back rotation in 40 degree～140 degree scopes, also driving fork when fixed axis comes back rotation swings back and forth, and balance staff is also moved around in 40 degree～140 degree scopes, and moving forward and backward thereby drive fire grate, the fixed axis that fire grate drives the rear end more in like manner rotates, the fire grate that moves around and shake falls in the deashing chamber coal ash, finishes deashing.

Described heating delivery port 21 is lower than water courage upper end water layer 20 height.The heating delivery port is positioned at and adds layer upper end.And the water supply courage top that communicates, heating water inlet 15,8 phase water flowing courage bottoms.Described body of heater side and adding is interval with the

blind rivet

4,16 that anti-sealing courage rises outward between the layer.Body of heater bottom establishes bearing 12, to stablize body of heater.

During use, cold water self-heating water inlet enters water courage and perpendicular water pipe and the tilting and in-furnace hanging chamber of horizontal water pipe put, and flows out body of heater to the radiator hot-water supply from the heating delivery port again behind the burner hearth heat before and after absorbing.For the coal in the burner hearth is fully burnt and burning as early as possible, can all open the mouth door, it is outdoor that then burner hearth interior air in front and back directly enters the quick discharge of outlet flue, promptly produces the drawing fires effect, otherwise, can control burning of coal speed in the burner hearth.

In a word, the utlity model has the counter-burning type function, can save coal 50%, smokeless and dust emissions than traditional hot-water heating stove, free from environmental pollution, and volume is little, simple in structure, cost of manufacture and price is low, quick combustion, heat utilization efficiency highly improve 5%, body of heater does not have the operation of pressure that higher security is arranged, and uses the stoking deashing convenient and prolong 30% service life.Can promote the use of.
