Abstract

The utility model relates to a collinear pipe type boiler, heating stove or tea stove. In the utility model, the inner of a furnace body comprises a combustion chamber and a convection beam tube chamber, the inner of the convection beam tube chamber is provided with a plurality of convection tubes which are parallelly arranged, and each convection tube is sheathed with an ash-removing ring in sliding fit mode; each ash-removing ring is respectively connected into integration on a plane by a connecting rod, and namely, an ash remover is formed; the ash remover is vertically fixed with a pushing rod which penetrates through a sleeve pipe and is led outside the furnace body. The utility model can remove the collecting dust and ashes of outside of tubes, improve the heat exchange efficiency and save fuels.

Description

Easy-to-clean ash collinear pipe type boiler

The utility model relates to a kind of collinear pipe type and burns vapour, the boiler of heating up water, water heater or drinking water boiler.

Heat up water or burn vapour with the collinear pipe type coal-burning boiler, carry out heat exchange, make water burn hot, boiled or burn till steam by the hot flue gas in the stove and the medium in the comb (as water etc.).After the collinear pipe type coal-burning boiler uses a period of time, comb has one deck dust stratification outward, can reach 20mm when the thickest, this moment is because of managing the effect of outer this lamination ash, make comb heat-transfer effect worse and worse, make that medium (water etc.) can not get deserved heat in the pipe, cause the cigarette temperature too high, emit in vain, wasted a large amount of coals.

The purpose of this utility model provides a kind of easy-to-clean ash collinear pipe type boiler, and the dust stratification on this stove can be removed outside the comb at any time guarantees that the medium in hot flue gas and the comb can carry out normal heat exchange, has improved the efficient of heat exchange, fuel saving.

The utility model is realized by the following formula mode.Include combustion chamber, convection current beam tube chamber in the body of heater of this easy-to-clean ash collinear pipe type boiler, in this convection current beam tube chamber, several convection tubes that are arranged in parallel are arranged, on described every convection tube all with the sheathed deashing ring of the mode that is slidingly matched, and described each deashing ring is all respectively by the connecting rod place of connecting into integral body in one plane, be dust remover, vertical fixing has push rod on this dust remover, this pull bar cover passes the sleeve pipe that is fixed on the described convection current beam tube locular wall, draws outside the described body of heater.

After this boiler uses a period of time, grasp pull bar, front and back push away, draw pull bar several times, can remove the dust stratification of convection tube on outer, guarantee that the heat exchange in the convection current beam tube chamber is normally carried out.

Described pull bar and sleeve pipe are respectively two, and the exposed end outside body of heater of described two pull bars links to each other by hand-held pole.Push away, draw with the hand operated hand-held pole, very convenient.

The internal diameter of described deashing ring is greater than the external diameter 3.6-4.4mm of described convection tube.Be that convection tube and deashing ring clear distance are about 2mm.Dust stratification on removing outside the convection tube like this generally is no more than about 2mm.

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment

As Fig. 1, Fig. 2, shown in Figure 3, this is a kind of collinear pipe type boiler, combuster 33 and convection current beam tube chamber 34 in this body of heater 32.Coal-feeding door 1 is arranged on body of heater 32, poke fire the door 2, deashing shutter 3, this collinear pipe type water heater in use, water enters the chuck 27 of body of heater 32 from water inlet 10, again from chuck 27 enters steel furnace grate tube 14 and the convection tube 12 the convection current beam tube chamber 34 under the combustion chamber 33.Simultaneously, drop into fuel from coal-feeding door 1, fuel is 33 internal combustion in the combustion chamber, and air can constantly enter from coal-feeding door 1.Imperfect combustion fuel and hot flue gas in second combustion chamber 35, enter fresh air by deashing shutter 3 by the outer wall of fire grate and steel furnace grate tube 14 in the combustion chamber 33, make the further burning in second combustion chamber 35 of imperfect combustion fuel.Hot flue gas enters in the convection current beam tube chamber 34 by the passage 36 of 34 of second combustion chamber 35 and convection current beam tube chambers, carries out discharging from throat 5 after the heat exchange with convection tube 12.Hot water in convection tube 12 and the steel furnace grate tube 14 flows out for using from delivery port 6.Lime-ash can be removed from deashing shutter 3 and shoot door 31.Because flue gas constantly passes through from the outer wall of convection tube 12, can make after after a while outside the pipe has one deck dust stratification, therefore can clear up dust stratification by dust remover.

As Fig. 5, shown in Figure 6, all sheathed deashing ring 21 on every convection tube 12, each deashing ring 21 is linked to be an integral body by connecting rod 24, becomes dust remover, and the exposed end outside body of heater that connects 23, two pull bars 23 of pull bar on the dust remover connects hand-held pole 29.As shown in Figure 4, fixed sleeving 40 on the envelope steel plate 26 in water jacket covering steel plate 25 on water jacket 27 and the water jacket, pull bar 23 can reciprocatingly slide in sleeve pipe 40.Boiler is under the normal operation situation, and deashing ring 21 is in the position on back spacing in the convection current beam tube chamber 34, position as shown in Figure 7, its position.When deashing, pulling pull bar 23 is moved pull bar 23 to position shown in Figure 8, and promptly deashing ring 21 is on the front limit, and push-and-pull can be removed convection tube 12 outer dust stratifications several times so repeatedly, and dust stratification is no more than about 2mm, has saved coal greatly.

Deashing ring of the present utility model can be steel loop.Connecting rod and pull bar can adopt reinforcing bar to make.

The foregoing description is a kind of collinear pipe type boiler that dust remover is housed, and the boiler of every employing vertical pipe, water heater or drinking water boiler can adopt dust remover of the present utility model, and therefore, protection domain of the present utility model is not limited to the foregoing description.Every boiler, water heater or drinking water boiler of the vertical pipe of dust remover of the present utility model of being equipped with is all in protection domain of the present utility model.

In sum, the dust stratification on easy-to-clean ash collinear pipe type boiler, water heater or drinking water boiler can be removed outside the comb at any time, the indoor heat exchange of assurance convection current beam tube is normally carried out, and improves the efficient of heat exchange, fuel saving.
