Description

Single handle control up-down rotary type furnace bottom

The utility model relates to the furnace bottom that uses on various hot-water heating stoves, the heating stove, more particularly is single handle control up-down rotary type furnace bottom.

At present, all there is following shortcoming in the furnace bottom of the various coal furnaces that people use: the neutral gear width that rises between the fire bars that leaks the slag draught effect immobilizes, promptly cannot regulate, in the process of lighting stove, need constantly clear up cinder, bulk cinder greater than the furnace bottom neutral gear, depending merely on the furnace bottom own activity does not go down clearly, must remove to collude cracked cinder to each neutral gear with fiery hook, collude less than the place just form the dead angle, because firmly make closely knit that the coal seam of burning becomes at the bottom of the travelling oven again easily, this all influences the ventilation of stove and is unfavorable for burning of coal.

The purpose of this utility model is exactly that a kind of furnace bottom of controlling its lifting and positive and negative rotation by single handle will be provided, this furnace bottom setting height(from bottom) is low, simple in structure, cost is low, easy to operate, under the situation that guarantees coal-fired normal combustion, can arbitrarily transfer the neutral gear width on the furnace bottom of wide upper strata, again can broken bulk cinder, guarantee the ventilation voids between the fire coal.

In order to achieve the above object, technical solution of the present utility model is: this furnace bottom comprises upper and lower two-layer, the centre of pallet is the upper strata furnace bottom, lower floor's furnace bottom be located at the upper strata furnace bottom below, lower floor's furnace bottom is held by cramp bar, the centralized positioning post passes upper strata furnace bottom, lower floor's furnace bottom and cramp bar successively, and the boss of the two ends of this cramp bar and pallet lower surface links; The interlaced setting of annular fire bars on the upper and lower layer furnace bottom, lower floor's furnace bottom is provided with broken post; Lower floor's furnace bottom is provided with the circular arc projection that can control its lifting and positive and negative rotation; Lower floor's furnace bottom is provided with transmission mechanism.

This transmission mechanism comprises rotating shaft and drive link, and this rotating shaft is located at the extension of the radially fire bars of lower floor's furnace bottom, and this drive link and rotating shaft form movingly.

This circular arc projection is positioned at the lower surface of lower floor's furnace bottom, this circular arc projection comprises and is positioned on the same circumference and the identical but two-part structure that relatively oppositely be provided with of structure, every partial arc shape projection comprises two sections, and wherein one section gradient is 40 °-80 °, and another section gradient is 1 °-5 °.

Because the upper strata furnace bottom maintains static and can support coal-fired normal combustion, and lower floor's furnace bottom can move up and down when being broken cinder rotating, promptly transfer the neutral gear width between the annular fire bars of wide upper strata furnace bottom, be convenient to the thorough removing of cinder, also increased the ventilation voids between the coal-fired layer, help burning of coal, this furnace bottom setting height(from bottom) is low, it is fast to be used on the hot-water heating stove backwater, structure and manufacturing process are simple, and cost is low, and be easy to operate, time saving and energy saving, single handle can be controlled the lifting and positive and negative the rotatablely moving of furnace bottom.

Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail:

Description of drawings: Fig. 1 is the partial sectional view of this furnace bottom

Fig. 2 is the A-A cutaway view of Fig. 1

Fig. 3 is the B-B cutaway view of Fig. 2

By Fig. 1,2,3 as can be known, this furnace bottom comprises upper strata furnace bottom 1 and lower floor's furnace bottom 2, the centre of pallet 7 is the upper strata furnace bottom, lower floor's furnace bottom by centralized positioning post 6 and cramp bar 5 be arranged on the upper strata furnace bottom below, lower floor's furnace bottom is held by cramp bar all the time, this centralized positioning post passes the centre of upper strata furnace bottom and lower floor's furnace bottom and the middle part of cramp bar successively, and the lower surface of this pallet 7 is provided with a pair of downward boss 7-1, and the two ends with cramp bar link respectively.Extension at the radially fire bars 2-4 of lower floor's furnace bottom is provided with rotating shaft 4, and this rotating shaft and drive link 3 form movingly.

Relatively be provided with on the lower surface of lower floor's furnace bottom 2 and be positioned on the same circumference and the identical but two parts circular arc projection 2-2 that oppositely be provided with of structure, every partial arc shape projection 2-2 includes 2 sections that are coupled to each other together, first section is that gradient is 1 °-5 ° a circular arc projection, this section effect is to make lower floor's furnace bottom 2 all the time near upper strata furnace bottom 1, to guarantee the broken cinder of broken when rotated post 2-1 of lower floor's furnace bottom and fire bars energy: second section is that gradient is the circular arc projections in 40 ° of-80 ° of scopes, the effect of this section is to make lower floor's furnace bottom fall below, and lean against on the cramp bar, make between the fire bars on the furnace bottom of upper strata the neutral gear width for maximum.Can clean out cinder better up hill and dale like this.The ultimate range that lower floor's furnace bottom moves down is 4-8cm.

Annular fire bars on the upper strata furnace bottom 1 and the interlaced setting of annular fire bars on lower floor's furnace bottom, be that neutral gear between annular fire bars and the lower floor annular fire bars on the furnace bottom of upper strata is corresponding, the best overlapped setting of radially fire bars on the upper and lower layer furnace bottom, lower floor's furnace bottom is provided with broken post upwards among the figure, this fragmentation post can be done positive and negative rotatablely moving and upper and lower moving in the neutral gear between the annular fire bars of upper strata furnace bottom, the cross section of this fragmentation post is prismatic, has sharp seamed edge.Certainly,, can increase the quantity of broken post, also broken post can be set on the furnace bottom of upper strata for the fire coal of easy caking.The height of broken post is a principle not burn, and the broken post of lower floor is higher than the broken post in upper strata, and the highest broken post generally exceeds about 2 centimeters of upper strata furnace bottoms, and this highly is the retention layer of coal-fired slag, can not burnt.Annular fire bars number on this furnace bottom can be determined according to the burner hearth internal diameter size of coal furnace.This fragmentation post and fire bars can be cast as one, and also can adopt resistant to elevated temperatures alloy material, and manufacturing is packed in above the furnace bottom more separately.

During use, with hand push or draw drive link, can make lower floor's furnace bottom in 0 ° of-180 ° of scope, realize doing along the upper and lower of centralized positioning post in the positive and negative rotation and move.This lower floor's furnace bottom is in positive and negative rotation with when moving up and down, and the circular arc projection of its lower surface contacts with cramp bar all the time.
