Abstract

The utility model relates to a hollow combined fire grate device. The hollow combined fire grate device is characterized in that the hollow combined fire grate device is combined by a front air cavity, a rear air cavity, a left air pillow, a right air pillow, a front bracket, a rear bracket, and hollow grates; the front air cavity is connected with the front bracket; the rear air cavity is connected with the rear bracket; the hollow grates are arranged on the front and the rear brackets.

Description

Hollow combined fire grate device

A. the utility model relates to a kind of kiln combustibility that is used to improve, the composite set of the coal-saving of protection environment.Be applicable to pottery magnetic kiln, forge furnace, steel rolling furnace, annealing furnace of various burning coals etc.

B. the combustion system of existing various kilns all is that the naked light that adopts just burns basically at present, and promptly upper coal feeding is slagged tap down, and air enters the coal seam by fire grate bottom.No matter be nature air draught or air blast, all can not make the sufficient combustion oxygen supply, so fire coal can not fully burn, cause a large amount of unburnt charcoal ash particulate and hydrocarbon to discharge, cause waste on the one hand, main is to cause serious environmental to pollute.

C. task of the present utility model be exactly overcome existing kiln because of over-emitting black exhaust causes a large amount of pollutions and the coal-fired shortcoming of waste; and a kind of novel hollow combined fire grate device is provided, reach coal-saving, protect environment and keep the purpose of original natural air draught fire grate characteristics.

D. the purpose of this utility model is achieved through the following technical solutions: the hollow combined fire grate device of employing is to integrate nature air draught and mechanical air blast, natural wind is by the burning zone that enters burner hearth between the hollow fire grate between the gap, guarantee coal-fired oxygen supply, and the air blast of air blast enters from front wind cavity, enters rear wind cavity and left right wind pillow and after wind pillow again through hollow fire grate.Burning zone is gone into a wind in wind hole by hollow fire grate, for the burning in coal seam provides all air quantity of even abundance, fire coal is fully burned.Volatile matter in combustion process mainly is carbon compound and carbon particle, volatilization is flown away on kiln top (is exactly black smoke and the pollutant that is discharged in chimney and the environment as untimely processing) again under the high temperature secondary wind effect that is provided by the wind hole on the left right wind pillow, make carbon particle, carbon compound obtains abundant oxygen supply burning once more.

E. compare with existing kiln, the kiln that hollow fire grate device is installed has following characteristics:

Under the identical situation of grate area, the combustion thermal efficiency height.

Quick heating in the kiln shortens firing period, improves man-haur efficiency.

Fire coal can be fully burned, and over-emitting black exhaust is not economized on coal significantly, helps protecting environment.

F. concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the structure chart according to the hollow fire grate device that the utility model proposes, describe in detail below in conjunction with Fig. 1, according to the details of the concrete device that the utility model proposes and working condition as can be seen: hollow combined fire grate device is made up of front wind cavity (1), rear wind cavity (2), front rack (3), tail-bracket (4), left wind pillow (5), right wind pillow (6), after wind pillow (7), hollow stove (8) attachment screw (9) of symmetry.Fire coal is added on the hollow combined fire grate (8), air blast enters mechanical wind through hollow combined fire grate (8) from isobaric air compartment front wind cavity (1) and enters isobaric air compartment rear wind cavity (2), left wind pillow (5), right wind pillow (6), a wind of coal-fired layer is supplied with evenly sufficient air quantity by the wind hole of hollow fire grate (8), and fire coal is fully burned.Coal-fired in combustion process, discharge a large amount of volatile matters, mainly be carbon compound and carbon particle, floating on burner hearth, during through left wind pillow (5), right wind pillow (6), under an amount of high temperature secondary wind action that blows out in the left right wind pillow, make carbon compound and carbon particle be able to abundant burning, reaching the purpose of the joint cigarette that eliminates smoke.

Claims

1. hollow combined fire grate device, it is characterized in that combining by front wind cavity, rear wind cavity, left wind pillow, right wind pillow, front rack, tail-bracket and hollow fire grate, front wind cavity is connected with front rack, and rear wind cavity is connected with tail-bracket, and hollow fire grate is placed on the carriage of front and back.

2. hollow combined fire grate device according to claim 1 is characterized in that the left air-out oral pore on left wind pillow and the forward and backward wind chamber joins, and the right air-out oral pore in right wind pillow and forward and backward wind chamber joins, and makes it to constitute frame mounting.

3. hollow combined fire grate device according to claim 1 and 2 is characterized in that on the hollow fire grate and the inboard of left right wind pillow all is equipped with the exhaust vent of plurality of rows, to guarantee the supply of wind and secondary wind.
