Abstract

The utility model relates to an oil heating furnace for a forging process. The oil heating furnace for a forging process has the advantages of safe gasification, less furnace smoke for combustion, and high thermal efficiency. A feeding inlet is arranged on one end of the furnace body. A feeding outlet is arranged on the other end of the furnace body. A horn-shaped through hole whose opening is arranged inwards is arranged on one side face of the furnace body. A suspension bracket is also fixed on the side face of the furnace body and is positioned above the through hole. A sliding rail is respectively arranged on both sides of the suspension bracket. A burner which is one type of BT14G, BT26G, BT34G, BT40G produced by Italy is hung and connected to the sliding rail through an arranged roller and a connected pull rod and is rightly opposite to the through hole. The burner is electrically connected with a control box. The heating furnace is used for forging metal pieces and heating.

Description

The fuel oil forge furnace

The utility model relates to oil burner.

Because selection, configuration and the relevant structural design of burner is reasonable inadequately, there is the burner poor performance in existing forging fuel oil heating and causes gasification of fuel oil incomplete, and the result is that fuel consumption is big, discharges a large amount of flue gases during burning and causes environmental pollution.This class oil burner also must dispose large blower, has so not only increased occupation area of equipment, has also increased work noise, and cost of equipment is increased.Nobody is appropriate to be selected and rationally reequiped the good burner of gasification performance, is applied to forge furnace, fuel utilization ratio is greatly improved and alleviates environmental pollution significantly.

The purpose of this utility model is to provide a kind of fuel utilization ratio height, and it is comparatively complete to burn, the fuel oil forge furnace that exhaust smoke level is few.

The technical solution of the utility model fuel oil forge furnace is to establish the charging aperture other end in body of heater one end to establish discharging opening corresponding to the burner hearth two ends, the body of heater side has the through hole of uncovered loudspeaker tubular inwardly, this through hole internal orifice is corresponding to residing fovea superior bow top in the burner hearth, its special character is, the residing body of heater of said through hole side, be fixed with hanger, install Italy on the hanger and produced BT14G, BT26G, BT34G, one of BT40G model comprise combustion head, its combustion head of the burner of the oil suction mouth of pipe and the oil return mouth of pipe is right against through hole, this burner can move according to hanger, and moving direction is axially consistent with through hole.

The utility model fuel oil forge furnace because the burner that Italy produces BT14G, BT26G, one of BT34G, BT40G model is installed, is greatly improved the stove combustibility.Said this burner once had the burning of human in miniature boiler, but did not use on forge furnace.The utility model mainly is to select to have disposed this burner, and its control section has been done appropriate improvement, and this heating furnace has been made in global design, has obtained beyond thought good result.On probation show that this heating furnace fuel combustion is complete, almost do not have visible stove cigarette to discharge during burning, thereby saved fuel oil, alleviated environmental pollution again significantly.Try out and show that compare with existing fuel oil forge furnace, this heating furnace can be saved fuel oil about 30 percent.Owing to transformed electrical control part, make this furnace operation easy to use, reliable besides.

Below in conjunction with description of drawings embodiment of the present utility model.

Fig. 1 is the utility model fuel oil forge furnace contour structures schematic diagram;

Fig. 2 is this heating furnace transverse sectional view;

Fig. 3 is this heating furnace combustion controlling circuit schematic diagram.

Embodiment 1 fuel oil forge furnace, mount body of heater 2 on the grate 9, body of heater 2 one ends are established charging aperture device fire door 6 on it, body of heater 2 other ends are established discharging opening, this charging aperture and discharging opening are corresponding to the burner hearth two ends, the body of heater side has the through hole 12 of uncovered loudspeaker tubular inwardly, this through hole internal orifice is corresponding to residing fovea superior bow top 11 in the burner hearth, through hole corresponding position, body of heater side is provided with Italy and produces BT14G, BT26G, BT34G, one of BT40G model comprise combustion head 4-1, the burner 4 of oil suction mouth of pipe 4-2 and oil return mouth of pipe 4-3, this is connected with pull bar above burner, the pull bar top is provided with on the slide rail that roller mount falls within fixing hanger 3 both sides, body of heater side.The oil suction mouth of pipe 4-2 of burner and oil return mouth of pipe 4-3 connect respectively through fuel sucking pipe 10 and oil return pipe 1 and lead in oil tank, are connected with filter 7 and prime filter 8 on the fuel sucking pipe.Burner 4 is electrically connected with control cabinet, and wherein control circuit as shown in Figure 3.

1G is an air switch among Fig. 3, and SB1, SB3 are normally closed switch, and SB2, SB4, SB5 are normal open switch, and 1C is together with 1C1,122, and 2C is a relay together with 2C1,2C2.When starting shooting after the 1G closure,, make 1C1 adhesive conducting, blower fan M work through 1C by switch S B2 energising; 1C2 conducting simultaneously treats down that the step starts.By switch S B4, make the 2C2 adhesive through 2C, oil pump FV work; 2C1 conducting simultaneously makes 1C1 when SB3 does not turn-off oil pump FV, can not be turn-offed and the blowing-out machine by SB1, assurance can only be after stopping oil pump just possible blowing-out machine.When driving oil pump by SB4 by SB5 initial igniter TR ignition.During shutdown, after pump switch SB3 is closed in elder generation, could Blowing stopper switch S B1.
