Abstract

The utility model discloses an afterheat recycling device for a forging furnace, comprising a furnace body, a furnace door, a heat insulation tank and a water using area, wherein the furnace body is provided with a furnace door fixing orifice; the furnace door is fixed by a bolt pin and comprises a furnace door frame and a heat conduction plate arranged in the furnace door frame; an S-shaped heat resisting metal guide pipe is paved in the heat conduction plate; the metal guide pipe is extended out from a hinge at one side of a heat conduction plate; the upper end of the metal guide pipe is provided with a water inlet; the lower end of the metal guide pipe is provided with a first water outlet pipe; and cooling water enters the heat conduction plate of the furnace door from the water inlet and is discharged from the first water outlet pipe. The upper end of a heat insulation tank is provided with a three-way valve and two parallel ports, wherein one port is conducted to a second water outlet pipe; the other port is toward the lower end and is conducted to the heat insulation tank; and the second water outlet pipe and a heat water pipe are connected to the water using area. In the working process, the afterheat recycling device for the forging furnace carries away heat accumulated on the furnace door to prevent the furnace door from being burned out in the long-time high temperature operation, thus improving the durability of the furnace door. Circulating water is used for living quarters after being heated, thus realizing the energy conservation.

Description

Forge furnace residual heat recovery device

Technical field

The utility model relates to the boiler fitting apparatus field, specifically forge furnace residual heat recovery device.

Background technology

Existing fire door mostly is the solid hermetically enclosed formula structure of irony, and in the course of the work, a large amount of heats can be transmitted on the fire door, and long-time hot operation can burn out fire door, must frequently change; Simultaneously, workman's bathing pool hot water of forge plant adopts burning hot iron piece to put into the cold water heating more, and is dangerous and cumbersome.

Summary of the invention

In view of the defective that prior art exists, the technical solution main purpose that the utility model adopts is to provide a kind of forging of heat conduction fire door of heating, and improves the durability of fire door.

For achieving the above object, the utility model forge furnace residual heat recovery device is characterized in that: comprise body of heater, and fire door, the insulation jar, the Water District constitutes.The fire door fixing hole is arranged on the body of heater, by the fixing fire door of pin, fire door is made up of firedoor frame and the heat-conducting plate that is installed in the firedoor frame, S type shop heating resisting metal conduit in the heat-conducting plate, metal catheter stretches out from heat-conducting plate hinge on one side, and the upper end is a water inlet, and the lower end is first outlet pipe, cooling water enters from water inlet in the heat-conducting plate of fire door, discharges from first outlet pipe.There is triple valve a described insulation jar upper end, two parallel ports, and an end feeds second outlet pipe, and an end is in the lower end feeds the insulation jar, and second outlet pipe and hot-water line are connected to the Water District.

After adopting such scheme, compared with prior art have following beneficial effect: the utility model is taken away the heat accumulative total on the fire door in the course of the work, avoids long-time hot operation to burn out fire door, improves the durability of fire door.After being heated, recirculated water is used for the living area water, energy-saving and emission-reduction.
