Description

The pitch thawing furnace

Technical field

The utility model relates to a kind of pitch thawing apparatus.

Background technology

Pitch is widely used material during building operation and material of construction are produced, as build roof water-proof and handle, the sticking paper production of oil etc., the pitch that construction and production unit are bought all is blocky, the pitch of the shape of determining will be heated during use can construct after melting and produce use.It is to adopt metal trough or big iron pan directly to endure with burning mostly that the bituminous device is melted in general working-yard, the thawing apparatus that also has is cooking stove to be set simply make the thawing furnace that one constitutes by iron plate under the pot body, itself and the big iron pan of aforesaid use are directly endured the difference that does not have in essence with burning, poor stability during this thawing device for asphalt uses, its open pot body and burning make bitumen flue gas and combustion product gases directly discharge serious environment pollution.For overcoming the shortcoming that this pitch melts, I also once disclosed a kind of pitch melter in the CN9823717 patent.

The utility model content

The purpose of this utility model provides a kind of safe, energy-conservation, free of contamination pitch thawing furnace easy to use.

Technical pattern of the present utility model includes shell 1, be arranged on the thawing drum 2 in the shell 1, melt drum loam cake 3, on loam cake 3, offer pitch feeding door 31a, 31b, offer discharge port 20 in the bottom of melting drum 2, loam cake 3 is provided with the agitator that is driven by the motor transmission, stir melting the pitch that melts in the drum 2 by paddle, form end heating chamber 4 between the bottom of thawing drum 2 and the bottom of shell 1, be provided with roasting kiln 5 in the front side of shell 1, on the lower wall of the front side of shell 1, offer the flue 45 of 51 of connection end heating chamber 4 and roasting kiln 5 combustion chambers, middle and lower part in melting drum 2 offers heat exchange smoke pipe 21a, 21b, hot flue gas in the end heating chamber 4 enters heat exchange smoke pipe 21a by flue 10,21b is discharged by smoke outlet 15 again, for eliminating the poisonous bitumen flue gas that asphalt melting produced, on upper end of melting drum 2 or loam cake 3, offer lead to roasting kiln 5 fire grates 52 bottom furnace chambers 53

draw gas flue

8a, 8b makes bitumen flue gas eliminate through fire grate 52 and combustion chamber 51 heating flames.Be provided with device for abatement of smoke and dust 9 for eliminating flue dust at the rear side of shell 1,

The utility model is rational in infrastructure, the heat utilization efficiency height, and good heat preservation performance, easy to operate, use flexibly, closed thawing, poisonous bitumen flue gas can not be excessive, and is free from environmental pollution, is furnished with the wet type device for abatement of smoke and dust, and no flue dust is discharged, but the qualified discharge flue gas.Roasting kiln 5 places and melts outside the drum 2; not only fire savety is good; and carry out heating and melting by end heating chamber 4 and heat exchange smoke pipe 21a, the 21b that melts under the drum 2; safety in utilization is good, is not easy to produce to overdo, and is convenient to operation control; the promptly anti-thawing drum 2 of the body skin of sealing exposes the high temperature appearance; the fender Working environment is improved, can reach the heat preservation energy-saving effect simultaneously to melting 2 safeguard protections of drum again.
