Abstract

The utility model discloses a novel rotary converter which comprises a hearth, an air inlet pipe and a vent pipe, wherein a furnace bridge is arranged in the hearth, a support plate is fixedly connected with the outlet end of the air inlet pipe and connected with the vent pipe through an inner bearing and an outer bearing, which are mounted on the support plate; the upper part of the vent pipe extends into the hearth and is fixed with the bottom of the hearth; an air baffle is arranged at the outlet end of the pipe body of the vent pipe extending into the hearth; vent holes are circumferentially distributed on the side wall of the pipe body of the vent pipe; air introduced via the air inlet pipe flows out through the vent holes and fully contacts with a fuel positioned above the furnace bridge, resulting in complete combustion of the fuel, so that the heating temperature in the hearth is risen to rapidly heat metal members. Accordingly, the fuel loss is reduced, the production cost is lowered, the energy consumption is reduced, and a promotional value is obtained..

Description

A kind of Novel rotary converter

Technical field

The utility model relates to the metal smelt technical field, relates in particular to a kind of remarkable enhancing burner hearth internal combustion temperature, improves the Novel rotary converter of metal material materials and parts firing rate.

Background technology

Traditional rotary converter is usually around its body of heater axis rotation, in its burner hearth by constantly providing sufficient air to fuel, thereby satisfy various metal material materials and parts are carried out the fire box temperature requirement of high-temperature heating, but the rotary converter ubiquity fuel that adopts at present extensively with air-supplied contact insufficient, can not give full play to the heat that fuel combustion can discharge, thereby make metal material materials and parts firing rate slow, cause object longer heat time heating time, fuel expends even more serious, has increased the production cost burden.

The utility model content

In order to overcome the existing technological deficiency of above-mentioned suspender, it is a kind of simple in structure, easy for installation that the purpose of this utility model is to provide, and significantly strengthens burner hearth internal combustion temperature, improves the Novel rotary converter of metal material materials and parts firing rate.

In order to achieve the above object, the utility model is achieved through the following technical solutions: the utility model is a kind of Novel rotary converter, comprise burner hearth, blast pipe and ventilation duct, wherein be provided with grate in the burner hearth, the blast pipe port of export is fixedly connected with supporting plate, and connects with ventilation duct by inner bearing and the outer bearing that is installed on the supporting plate, the top of ventilation duct probes into burner hearth, and fix with burner hearth bottom, the body port of export in ventilation duct probes into burner hearth is provided with deep bead, and tube wall circumferentially is furnished with air vent.The ventilation duct port of export seals the mouth end by deep bead, and at the ventilation duct tube wall that probes into burner hearth air vent is set, the air that blast pipe is introduced is dispersed by air vent, and fully contact with the fuel of the burning of grate top, make fuel be able to abundant burning, thereby improve heating-up temperature in the burner hearth, be able to Fast Heating metal material materials and parts, reduce fuel consumption, save production cost.

As optimization, described blast pipe is L-shaped, and its underpart corner part is fixed on the base plate, and by reinforcement and bottom plate connecting, strengthens the steadiness of structure.

As optimization, the upper opening of described burner hearth is provided with gear fire cover plate, and its inwall is provided with refractory material, can to play in the burner hearth insulation, minimizing heat waste booster action.

Compared with prior art, the beneficial effects of the utility model are: the utility model is controlled the flow direction of air stream and the distribution in burner hearth by the air outlet that changes ventilation duct, thereby reach the purpose that improves the fuel combustion degree, and then heating-up temperature in the raising burner hearth, be conducive to improve the firing rate of metal material materials and parts, reduce heat time heating time, reduced expending of fuel, saved production cost.The utility model is simple in structure, and is easy for installation, is convenient to be suitable for, and has higher promotional value for energy-saving consumption-reducing.

Description of drawings

The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model top view.

Mark among the figure: burner hearth 1, blast pipe 2, ventilation duct 3, supporting plate 4, inner bearing 5, outer bearing 6, grate 7, deep bead 8, air vent 9, base plate 10, reinforcement 11, gear fire cover plate 12, flame retardant coating 13.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

As shown in Fig. 1 and Fig. 2, the utility model comprises burner hearth 1, blast pipe 2 and ventilation duct 3, wherein be provided with grate 7 in the burner hearth 1, and be positioned at burner hearth 1 top, provide the fuel of heat for placing to burn, blast pipe 2 is L-shaped, be positioned at the device bottom, its underpart corner part is fixed on the base plate 10, and by reinforcement 11 and bottom plate connecting, all be connected to a fixed by the mode of welding between blast pipe 2 and base plate 10 and reinforcement 11 and blast pipe 2 and the base plate, be fixedly connected with supporting plate 4 at blast pipe 2 top port of export outer walls, and connect with ventilation duct 3 by inner bearing 5 and the outer bearing 6 that is installed on the supporting plate 4, and the top of ventilation duct 3 probes in the burner hearth 1, and be fixedly connected with burner hearth 1 bottom, are connected with outer bearing and being connected of ventilation duct 3 by inner bearing 5, can realize that the burner hearth 1 that ventilation duct 2 and top connect can rotate along the device axis.The port of export of the body in ventilation duct 3 probes into burner hearth 1 is provided with deep bead 8 with the sealing of ventilation duct 3 ports of export, then circumferentially is furnished with air vent 9 at the tube wall that probes into burner hearth 1 part.Be provided with gear fire cover plate 12 at the upper opening of burner hearth 1, its inwall is provided with flame retardant coating 13, can to play in the burner hearth 1 insulation, minimizing heat waste booster action.

When the utility model is in running status, place the fuel that is in fired state on the grate 7, and the entrance point of blast pipe 2 injects the air that supplies fuel combustion by air-blast device, by the guiding air of blast pipe 2 to ventilation duct 3, because ventilation duct 3 ports of export seal the mouth end by deep bead 7, and at ventilation duct 3 tube walls that probe into burner hearth 1 air vent 9 is set, discharged by air vent 9 by the air that blast pipe 2 is introduced, disperse, increased the fuel contact area with the burning of grate 7 tops, make fuel be able to abundant burning, thereby heating-up temperature in the raising burner hearth, be able to Fast Heating and place fuel metal material materials and parts, shortened the heat time heating time of metal material materials and parts, reduced fuel consumption, saved production cost.
