Abstract

The utility model discloses a smoke discharging air duct for a rare earth burning furnace. The smoke discharging air duct comprises a smoke discharging air pipe arranged on the top of a furnace body and is characterized in that the smoke discharging air pipe comprises a first exhaust pipe and a second exhaust pipe; the first and second exhaust pipes have an inverted U-shaped structure respectively; air inlets of the first and second exhaust pipes are formed on the top of the furnace body, and air outlets of the first and second exhaust pipes are respectively formed at a feeding hole and a discharge hole of the furnace body. The first and second exhaust pipes have the inverted U-shaped structure, the air inlets of the first and second exhaust pipes are formed on the top of the furnace body and the air outlets of the first and second exhaust pipes are respectively formed at the feeding hole and the discharge hole of the furnace body, so that an aim of discharging smoke in the furnace is fulfilled, heat which is easily lost at the feeding hole and the discharge hole in the furnace is closed in the furnace, the heat loss in the furnace is small, and the aims of reducing waste, improving production environment and reducing production cost are further fulfilled.

Description

A kind of smoke duct of rare earth firing stove

Technical field

The utility model relates to rare earth firing stove field, is specifically related to a kind of smoke duct of rare earth firing stove.

Background technology

In Rare Earth Production industry, rare-earth products is in process of manufacture, incinerator is one of equipment that must use, existing incinerator is all generally rectangular structure, inner burner hearth is tunnel like structure, along being provided with calcination passage in the length direction of incinerator, at calcination passage periphery, be provided with heater, rare-earth products charging aperture from passage on metal conveyor belt enters, in passage, calcination is processed, reach after due performance, again from the discharging opening of passage out, the vertical exhaust duct that is provided with on body of heater, by drying the waste gas producing, upwards directly drain, and existing exhaust duct can be taken away a part of heat, simultaneously at the charging aperture of burner hearth passage and discharging opening a part of heat that also can scatter and disappear, adopt exhaust duct directly to drain drying the waste gas producing, so not only cause the waste of a lot of heat energy, the energy is not made full use of, cause the increase of enterprise's production cost, simultaneously easy contaminated environment, temperature in workshop is raise, cause workman's working environment to worsen, also further damaged workman's physical and mental health.

Utility model content

For solving the problems of the technologies described above, we have proposed a kind of smoke duct of rare earth firing stove, and to have reached when discharging fume in stove, thermal loss is few, cuts the waste, the object saving production cost.

For achieving the above object, the technical solution of the utility model is as follows:

A smoke duct for rare earth firing stove, comprises the smoke exhaust pipe of being located at body of heater top, it is characterized in that, described smoke exhaust pipe comprises first row airduct and second row airduct; Described first row airduct and second row airduct are inverted U structure, and its air inlet is all located at body of heater top, and its air outlet is located at respectively described body of heater charging aperture and discharging opening.

Preferably, the air inlet of described first row airduct and second row airduct interconnects by a blast pipe.

Preferably, described blast pipe is provided with smoke exhaust fan.

Pass through technique scheme, the utility model is by being all designed to described smoke exhaust pipe inverted U structure first row airduct and second row airduct, and its air inlet is all located at body of heater top, its air outlet is located at respectively described body of heater charging aperture and discharging opening, so not only reach the object to discharging fume in stove, simultaneously by stove easily from charging aperture and the shutoff of discharging opening dispersed heat in stove, realized when discharging fume in stove, furnace heat loss is few, further reached and cut the waste, improve production environment, and the object saving production cost.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is that the smoke duct of the disclosed a kind of rare earth firing stove of the utility model embodiment is located at the schematic diagram on incinerator;

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

The utility model provides a kind of smoke duct of rare earth firing stove, and to have reached when discharging fume in stove, thermal loss is few, cuts the waste, the object saving production cost.

Below in conjunction with embodiment and the specific embodiment, the utility model is described in further detail.

Embodiment.

As depicted in figs. 1 and 2, a kind of smoke duct of rare earth firing stove, comprises the smoke exhaust pipe of being located at body of heater 1 top, and described smoke exhaust pipe comprises first row airduct 2 and second row airduct 3; Described first row airduct 2 and second row airduct 3 are inverted U structure, and its air inlet is all located at body of heater 1 top, and its air outlet is located at respectively charging aperture 11 and the discharging opening 12 of described body of heater 1.

Wherein, the air inlet of described first row airduct 2 and second row airduct 3 interconnects by a blast pipe 4; In order to accelerate the smoke discharging effect in stove, described blast pipe 4 is provided with smoke exhaust fan 5.

In this example, because described smoke exhaust pipe is all designed to inverted U structure first row airduct 2 and second row airduct 3, and its air inlet is all located at body of heater 1 top, its air outlet is located at respectively charging aperture 11 and the discharging opening 12 of described body of heater 1, so not only reach the object to discharging fume in stove, simultaneously by stove easily from charging aperture 11 and discharging opening 12 dispersed heat shutoff in stove, thereby realized when discharging fume in stove, furnace heat loss is few, also further reached and cut the waste, improve production environment, and the object saving production cost.

Above-described is only the smoke duct preferred embodiment of a kind of rare earth firing stove of the present utility model; should be understood that; for the person of ordinary skill of the art; do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
