When working, the utility model can effectively control the exhaust emission. The asphalt processing device has the advantages of high heat efficiency and energy saving.

Description

The asphalt melting stove

The utility model relates to a kind of bituminous processing units.

In construction project, house repairing, the fields such as production of pipeline corrosion protection, linkrusta need be dissolved pitch and done raw material.Mostly use iron case or cauldron to burn when dissolving pitch now, pitch volatilizes a large amount of glance coals when being dissolved, the waste gas that produces when adding coal burning, severe contamination environment, waste energy.China's utility application numbers 88202745 discloses a kind of harmless province coal-tar pitch stove, the technical essential of this scheme is that upper and lower double-layer grate is set on the boiler, by apparatus for deivation glance coal is introduced lower floor's fire grate and burn cracking, glance coal significantly reduces after burning cracking, simultaneously because glance coal has combustion-supporting effect, it is remarkable to economize the coal effect, but this scheme still can not solve the pollution problem of coal smoke.

The purpose of this utility model provides a kind of purifying pitch cigarette and coal smoke simultaneously, and the asphalt melting stove of save energy.

For achieving the above object, asphalt melting stove of the present utility model adopts the structure of two cover combustion chambers and melting tank, wherein a cover combustion chamber and melting tank are as roasting kiln, another set of as process furnace, maintain red-hot coal ashes in the combustion chamber of process furnace, fill out coal in the combustion chamber of roasting kiln, sealed pot cover is all arranged at the melting tank top of every stove, sealed pot cover is provided with the flue that communicates with the combustion chamber bottom, and the glance coal that produces during with molten asphalt is introduced burner hearth and burned cracking.Utilize the burner hearth bottom secondary combustion of the flue on the top, combustion chamber that is located at roasting kiln with the waste gas introducing process furnace of coal burning generation simultaneously, the waste gas after secondary combustion is discharged by the flue on the top, combustion chamber that is located at process furnace.

After adopting such scheme, the glance coal that roasting kiln and process furnace produce is introduced in separately the burner hearth and burns, and the coal smoke that roasting kiln produces is introduced into secondary combustion in the burner hearth of process furnace, and objectionable impurities greatly reduces in the waste gas of discharge, simultaneously because the combustion-supporting effect of glance coal can be saved the coal consumption.

Further specify the utility model below in conjunction with drawings and Examples

Fig. 1 is a structure principle chart of the present utility model;

Fig. 2 is flue structure schematic diagram of the present utility model (rear view of Fig. 1);

Fig. 3 is the utility model A-A sectional view.

Fig. 1, asphalt melting stove shown in Figure 2 comprises stove A and stove B, stove A and stove B have combustion chamber and melting tank separately, cover sealed pot cover 1 on the melting tank, sealed pot cover 1 is provided with the flue 2 that communicates with the combustion chamber bottom, there is pitch pipeline 12 to link to each other between the melting tank of stove A and stove B, the top, combustion chamber of stove A is provided with the flue 3 that links to each other with the flue 2 of stove B, the top, combustion chamber of stove B is provided with the flue 4 that links to each other with the flue 2 of stove A, there is flue 5 to link to each other between flue 3 and the flue 4, flue 5 is provided with smoke outlet 8, resistance cigarette lock 6 synchronously is installed on flue 3 and the flue 5, with respect to synchronous resistance cigarette lock 6, the opposing party of smoke outlet 3, resistance cigarette lock 7 synchronously is installed on flue 4 and the flue 5.

During use, have pipeline to communicate between the melting tank of stove A and stove B, can with stove A or stove B one of them as roasting kiln, another is as process furnace.Suppose that stove A is as roasting kiln, stove B is as process furnace, make in the burner hearth of stove B and maintain red-hot coal ashes, in the burner hearth of stove A, fill out coal, the glance coal that produces when pitch is heated burns cracking by the burner hearth bottom that sealed pot cover 1 and flue 2 are introduced into the combustion chamber, the coal smoke that the combustion chamber of stove A produces enters in the flue on the top, combustion chamber that is arranged on stove A, can enter flue 3 or flue 5 respectively by this flue, to hinder cigarette lock 6 synchronously and open this moment, resistance cigarette lock 7 cuts out synchronously, this coal smoke can only be entered in the flue 2 of stove B by flue 3, with the burner hearth bottom secondary combustion that enters stove B after glance coal that stove B produces mixes, waste gas through secondary combustion enters in the flue that is arranged on top, stove B combustion chamber, can enter flue 4 or flue 5 respectively by this flue, but, hinder cigarette lock 7 synchronously and close because synchronous resistance cigarette lock 6 is opened, so waste gas can only enter flue 5, and by smoke outlet 8 discharges.Owing to do not fill out coal in the burner hearth of process furnace, and just maintain red-hot coal ashes, stove B can not be always uses as process furnace, when the coal among the stove B will after-flame, and the position that can switch synchronous resistance cigarette lock 6,7 simultaneously, being about to hinder cigarette lock 6 synchronously closes, resistance cigarette lock 7 is opened synchronously, and this moment, stove B was as roasting kiln, and stove A is as process furnace, fill out coal in stove B, so constantly wheel changes jobs.

In order to strengthen smoke discharging effect, at smoke outlet 8 places induced draft fan is installed in the present embodiment.

As shown in Figure 3, be heated evenly, improve heating efficiency in order to make the pitch in the melting tank.In the present embodiment flue 3 and flue 4 equal some pass its melting tank inside separately, and for the ease of cleaning flue inside, before stove A and stove B, be provided with smoke box 9, to smoke box 9 flue 1O is set by top, combustion chamber, to the body of heater rear portion flue 11 is set by smoke box 9, flue 11 is in body of heater rear portion and flue 3 and flue 5 or flue 4 and flue 5 connections.
