CN2392087Y - Integrated furnace chamber charging hopper structual component for garbage incineration furnace - Google Patents

Abstract

The utility model relates to a component of a garbage incineration furnace. The utility model is provided with a hopper of a feeding mechanism and a hearth body fixedly connected with the hopper. The hopper has a split-type structure, and the hopper is formed by fixedly connecting the upper part of the hopper, which is positioned above the hopper, and the lower part of the hopper, which is positioned below the hopper in the manner of obturation. The lower part of the hopper, which is made of heat resisting cast iron members, is provided with connecting ribs, the connecting ribs are arranged above the discharge hole at the lower part of the hopper, and the connecting ribs serving as inserts are fixed in a jack arch suspension girder in the front side of the front vault of the hearth body. While in use, the utility model can provide better air tightness for the garbage incineration furnace.

Description

The integral type burner hearth hopper construction part of domestic waste incineration

The utility model relates to a kind of parts of domestic waste incineration.

The hopper of existing its feeding mechanism of incinerator is made by the general steel plate of homogenous material, and the connected mode of this hopper and furnace chamber body is, the connector at the charging aperture place by being preset in hearth body is fixedlyed connected with hopper.But because of incinerator when the disposal of refuse, under the high temperature, the thermal coefficient of expansion of burner hearth and hopper differs bigger, easily make the connecting portion of burner hearth and hopper produce the slit, thereby make the airtight performance of incinerator relatively poor, the flue gas that incinerator is in operation produce produces herein and opens circuit, spreads to the garbage disposal workshop, has produced new pollution.

The purpose of this utility model is, the seal that can make domestic waste incineration when a kind of the use is provided is integral type burner hearth hopper construction part preferably.

The technical scheme that realizes the utility model purpose is, this structural member has the hopper of feeding mechanism and the hearth body of fixedlying connected with hopper, its design feature is, hopper is a split-type structural, hopper is made of with airtight the fixedlying connected in hopper bottom that is positioned at the below the hopper top that is positioned at the top, the hopper bottom that heat radiating type is strengthened heat-resisting cast iron spare formation is provided with dowel, dowel is arranged on the top of hopper bottom discharging opening, and dowel is fixed on as inserts in the jack arch overarm of preceding vault front side of hearth body.

The inclination alpha of vault and horizontal plane is 18～23 degree before the above-mentioned hearth body.

The utlity model has positive effect: (1) is close because of the thermal coefficient of expansion of heat-resisting cast iron and hearth body, so under the effect of the heat that waste incineration produced, the connecting portion of hopper and hearth body still keeps original annexation, thereby makes the seal of incinerator that certain guarantee arranged.(2) after vault before the furnace cavity and horizontal plane were provided with certain inclination angle, the heat radiation that incineration firing is sent reflexed to the rubbish baking zone morely, thus can accelerate rubbish at the rate of drying of baking zone, reduce the generation that produces toxic and harmful.

Drawing of the present utility model is described as follows:

Fig. 1 is a kind of schematic perspective view of the utility model hopper.

Fig. 2 is a kind of structural representation of the present utility model.

Fig. 3 is hopper and the interconnective partial enlarged drawing of hearth body among Fig. 2.

The utility model will be further described below in conjunction with drawings and Examples.

See Fig. 1, hopper 41 is a split-type structural.Make the hopper top 411 of shape as shown in the figure with the Q235A steel plate through operations such as blanking, welding, strengthen heat-resisting cast iron with heat radiating type and make hopper bottom 412 through cast, by securing member with hopper top 411 and hopper bottom 412 airtight being fixed together.Hopper bottom 412 is provided with dowel 412-1, and dowel 412-1 is arranged on the top of hopper bottom 412 discharging openings.

See Fig. 2, the dowel 412-1 of hopper bottom 412 hangs oneself from a beam in the jack arch of preceding vault 32 front sides of cast hearth body 3 and was fixed therein as inserts in 31 o'clock.

See Fig. 3, vault 32 is 20 degree with the inclination alpha of horizontal plane before the hearth body 3.

Claims (2)

1, a kind of integral type burner hearth hopper construction part of domestic waste incineration, have the hopper (41) of feeding mechanism (4) and the hearth body (3) of fixedlying connected with hopper (41), it is characterized in that, hopper (41) is a split-type structural, hopper (41) is by hopper top (411) that is positioned at the top and the airtight formation of fixedlying connected in hopper bottom (412) that is positioned at the below, the hopper bottom (412) that heat-resisting cast iron spare constitutes is provided with dowel (412-1), dowel (412-1) is arranged on the top of hopper bottom (412) discharging opening, and dowel (412-1) is fixed on as inserts in the jack arch overarm (31) of preceding vault (32) front side of hearth body (3).

2, the integral type burner hearth hopper construction part of domestic waste incineration according to claim 1 is characterized in that, the preceding vault of hearth body (3) (32) is 18～23 degree with the inclination alpha of horizontal plane.
