Description

Chimney-free grain drying boiler

The utility model relates to a kind of no chimney grain drying boiler that is used to dry grain.

It is reported, be used to dry the boiler of grain at present, generally be to heat the smoke exhaust pipe that is located in pot body, and the heat that smoke exhaust pipe sheds sent into grain drier by air blast by heating furnace.This boiler has by the smoke exhaust pipe of dry combustion method is fragile and breaks, and makes coal smoke and coal ash enter grain drier internal contamination grain, and needs to be provided with than weak points such as chimney stack and consumption coals.

The purpose of this utility model is in order to overcome the deficiency of above-mentioned prior art, provide a kind of reasonable in design, simple in structure, cost is low, have smoke elimination, dedusting, efficient, economize on coal, the no chimney grain drying boiler of long service life.

Technical solution of the present utility model is, in order to realize economizing on coal, eliminate smoke, improving the purpose of the thermal efficiency, designed and a kind ofly be furnished with the interior cover of the tuyere that has a down dip and be provided with the mouth of delivering coal that has suitable for reading that the overcoat of blast pipe constitutes by internal perisporium, the bottom has the peviform body of heater of slag-drip opening and slag-drip opening opening and closing element.But its opening and closing element plate or plug or door.Purpose in order to realize directly drying grain and removing flue dust becomes top to have air-vent the pot system, and the bottom has dust-exhausting port and erects the pot body that is equipped with some curved dedusting sheets with hot-wind inlet and the internal perisporium that the pot wall is tangent line.In order to improve dust removing effects, the middle part in the pot body is perpendicular to be equipped with some of being axially disposed within on the center-pole and to put at the opposite dedusting sheet of the dedusting bending tablet direction of internal wall pot body with erecting.The black smoke that is produced when getting rid of the coal initial combustion has exhaust opening at the top of pot body, and is provided with removable cover at the exhaust opening place.For the ease of removing flue dust, be hung with the well-bucket of sealing dust-exhausting port at the dust-exhausting port place of pot body bottom.In order to help the flue dust sedimentation water can be housed in well-bucket.Its peviform body of heater is installed in and is positioned at pot combustion chamber of body heat wind porch, and is provided with ajutage at the hot-wind inlet place.

The utility model compared with the prior art, one, because the body of heater that internal perisporium is furnished with the tuyere that has a down dip has been housed in heating clamber, Gu this can make coal be able to abundant burning, and eliminated black smoke.After tested, 0.5～0 grade of its oke exhaust blackness lingemann grade economizes on coal 30～40%, and ignition temperature can reach 1200 ℃, and slag contains charcoal 2.6%.In addition,, not only reduced the carbon deposit in the pot, helped conducting heat and having cancelled chimney owing to eliminated black smoke.Two, be hung with the well-bucket that water is housed owing to the pot body that is provided with the dedusting sheet in the pot system has been become, and at the dust-exhausting port place of pot body, therefore help dedusting.

Below in conjunction with accompanying drawing, describe a specific embodiment of the present utility model in detail.

Fig. 1 is a structural representation of the present utility model.

Referring to Fig. 1, a pot body 3 is that the top has exhaust opening 36, and upper lateral part has an air-vent 35, and what the following side had two symmetries is the hot-wind inlet 33 of tangent line with the pot wall, and the bottom has the cylindrical shape pot body of dedusting mouth 9.The bottom of pot body 3 is conical.36 places are welded with smoke exhaust pipe 37 at exhaust opening.At the axle bed 2 that is welded with suitable for reading of smoke exhaust pipe 37, and be equipped with by 38 removable covers that affect 1 of restricting by axostylus axostyle.Be welded with the induced duct 34 that is connected with grain drier at air-vent 35 places.Be welded with 12 curved plates 7 perpendicular the putting of the internal perisporium of pot body 3.Middle part in pot body 3 is fixed with perpendicular axially being welded on the center-pole 56 and putting at the opposite dedusting sheet 6 of dedusting sheet 7 bending directions of pot body 3 inwalls with erecting of putting by being welded in bearing support 4 on pot body 3 inwalls.On the shell wall at dust-exhausting port 9 places, be welded with bearing support 12 and sleeve pipe 13,18.In sleeve pipe 13, be inserted with crank 19.In sleeve pipe 18, be inserted with and prevent crank 19 rotating inserted links 20.There is the rope 16 that has suspension hook 17 in system at the two ends of crank 19.Suspension hook 17 hangs on the hanger 14 of two symmetries of well-bucket 15.Well-bucket 15 combines with dust-exhausting port 9 with the forward and backward of crank 19 or breaks away from.Be equipped with combustion chamber 8 and the ajutage 32 that has deliver coal mouth 10 and slag-drip opening 11 at hot-wind inlet 33 places of two symmetries.By bearing support 23 spill that has suitable for reading that is furnished with the interior cover 27 of the tuyere 28 that has a down dip and is provided with that the overcoat 26 of upper and lower blast pipe 25 is welded into by internal perisporium is installed and delivers coal mouthfuls 30 in combustion chamber 8, the bottom has the peviform body of heater 21 of circular row cinder notch 29 and slag-drip opening opening and closing element 22.The angle of inclination of its tuyere 28 is 36 °.Its opening and closing element 22 is oval plates.At the outer wall of interior cover 27, the inwall of overcoat 26 be welded with respectively each other overlap joint every inner panel 24.8 outer wall is built in the combustion chamber insulating brick 31.
