The utility model mainly comprises a casing, a blast pipe, an air duct, a smoke tube, a furnace door and a fire bar; wherein, a first casing, a second casing, a third casing and a fourth casing are respectively arranged in sequence from outside to inside on a bottom board; under the fourth casing the fire bar is positioned and one side of the fourth casing is provided with the furnace door; one side of the third casing is equipped with an air duct; both ends of a heat-transfer pipe are respectively connected with the tops of the third and the fourth casings; one side of the second casing is provided with the smoke tube; heating pipes are distributed in the gap between the side walls of the second and the third casings with the air inlets arranged in the space between the first and the second casings and the air outlets in the space between the third and the fourth casings; one side of the first casing is equipped with the blast pipe.

Description

Hot-blast stove
Affiliated technical field
The utility model relates to a kind of hot-blast stove, is a kind of stove that adds hot-air specifically.
Background technology
Existing hot-blast stove is varied, as the hot-blast stove to mine down-hole and plant and other field heat air delivery, need the certain mass requirement be arranged to the hot blast of carrying, and make the air after the heating not contaminated.Chinese patent CN2077096U discloses a kind of hot-blast stove, and its structure can make the air after the heating not contaminated.But the vertical airduct of this utility model places in the burner hearth, and service life is short; In addition, air is directly discharged after importing annular wind chamber into by vertical airduct, so the heat exchanger time of air is short, and efficient is low.
Summary of the invention
The purpose of this utility model provides a kind of long service life, the hot-blast stove that the thermal efficiency is higher.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of hot-blast stove, comprise housing, blast pipe, discharge pipe, chimney, fire door, fire grate etc., be respectively first housing, second housing, the 3rd housing and the 4th housing on the base plate from outside to inside; The 4th housing below is provided with fire grate, and a side is provided with fire door; The 3rd housing one side is provided with discharge pipe; The heat-transfer pipe two ends connect the 3rd housing and the 4th case top respectively; Second housing, one side is provided with chimney; Heat pipe is distributed in the space between second housing and the 3rd housing sidewall, and the air inlet of heat pipe leads in the space between first housing and second housing, and the gas outlet of heat pipe leads in the space between the 3rd housing and the 4th housing; First housing, one side is provided with blast pipe.
Described heat pipe is " U " type bend pipe.
Be lined with refractory material in described the 4th housing.
The beneficial effects of the utility model are that heat pipe is not set directly in the burner hearth, so increase service life; Therefore air will heat through the second heating chamber between a heating clamber, second housing and the 3rd housing between first housing and second housing and three heating clambers between the 3rd housing and the 4th housing, and to compare the efficiency of heating surface higher with background technology.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
Fig. 1, shown in Figure 2, the 3rd housing (2) and the 4th housing (7) are welded on the base plate (10), heat-transfer pipe (1) two ends pass the top of the 3rd housing (2) and the 4th housing (7) respectively, and are one with the 3rd housing (2) and the 4th housing (7) welded top respectively.The gas outlet of heat pipe (3) feeds in the space between the 3rd housing (2) and the 4th housing (7), and is welded on the 3rd housing (2).Second housing (5) bottom is welded on the base plate (10), and the air inlet of heat pipe (3) leads in the space between first housing (4) and second housing (5), and it is welded on second housing (5) top.First housing (4) is a shell, and its bottom is welded on the base plate (10).The outlet of blast pipe (12) is led in the space between first housing (4) and second housing (5), and be welded on first housing (4).The air inlet of discharge pipe (11) is led in the space between the 3rd housing (2) and the 4th housing (7), and be welded on the 3rd housing (2).The import of chimney (13) is led in the space between second housing (5) and the 3rd housing (2), and be welded on second housing (5).Fire door (6) is led in the 4th housing (7), and its internal orifice is welded on the 4th housing (7).At last known common refractory (9) is served as a contrast in the 4th housing (7), place upper fire-grating (8).Blast pipe (12), discharge pipe (11), chimney (13) and fire door (6) are with all housing walls that passed seal welding all.After above-mentioned installation, get final product operate as normal.The course of work is as follows: coal-fired burner hearth internal combustion in the 4th housing (7) also produces the hot gas that contains coal smoke in a large number, heat energy outwards transmits by the 4th housing (7) wall, hot gas also by flowing in the space of heat-transfer pipe (1) between the 3rd housing (2) and second housing (5), is discharged by chimney (13) at last simultaneously.Place that the heat pipe (3) in the space absorbs a large amount of heats between the 3rd housing (2) and second housing (5), and will manage in the space of importing into after interior cold air heats between the 3rd housing (2) and the 4th housing (7), cold air after the heating once heats again at this, at last hot gas is discharged from discharge pipe (11).Cold air enters in the space between first housing (4) and second housing (5) by blast pipe (12), at last the thermal process that is subjected to that enters postorder by the air inlet that places the heat pipe (3) in this space.The above-mentioned course of work repeatedly is heated cold air, and efficient is higher.The air that is heated is carried out to isolate with the hot gas that contains coal smoke and is passed through, and guarantees that the hot-air that produces is not contaminated.
