Abstract

The utility model discloses a novel leakproof ventilation adjustable flap grate, which is suitable for incinerators of solid waste materials. The leakproof ventilation adjustable flap grate is characterized in that cross sections of each flap of the grate are L-shaped; a plurality of flaps are overlapped successively, so as to prevent not burned enough small grains of the waste material and residual liquids from lower leakage. A narrow side of the flap is provided with notches, so as to achieve good ventilation, and the solid waste is enabled to burn completely. Each flap can be enabled to swing by the mechanical linkage effect; the aim of flapping the waste material can be obtained, and the ash removal work can be completed.

Description

Leakproof ventilation drop in leaf fire grate

The utility model discloses the leakproof ventilation drop in leaf fire grate in a kind of solid waste incineration stove.

Existing solid waste incineration stove fire grate has four kinds; One, dull and stereotyped fire grate, its characteristics: can prevent that insufficient burnt granule discarded object from falling, but ventilation condition is bad, is difficult for grilling thoroughly, fuel consumption is big, and efficiency of combustion is low.Two, fixed grate fire grate, its characteristics: aeration is good, can improve efficiency of combustion, but raffinate and insufficiently burnt granule discarded object easily drop to grey chamber, and influence treatment effect.Three, hand moving grate, its characteristics: can utilize handle to rotate and change the fire grate direction, stir discarded object, simultaneously can adjust the fire grate slit, with the control air quantity, reach the purpose that improves firing efficiency, but it can not avoid insufficient burnt granule discarded object and raffinate to leak down.Four, stoker fired grate, its characteristics: by the stoker fired grate operation, discarded object is evenly imported, and had the good ventilation performance, but it can not prevent that still insufficient burnt granule discarded object and raffinate from leaking down.

The purpose of this utility model, be to overcome contradiction on the present fire grate structure, if promptly ventilation condition is good, will cause under raffinate and the insufficient burnt granule discarded object and leak, if good leak-proof effect, can cause improper ventilation again, and the utility model provides a kind of solution this contradiction scheme, designed a kind of novel anti-leakage ventilation drop in leaf fire grate.

Following accompanying drawing is described the utility model embodiment.

Fig. 1 is this structural front view.

Fig. 2 is the burning duty of A-A cutaway view in this structural front view.

Fig. 3 is the turnover panel structural representation.

Fig. 4 is the deashing duty of this structure A-A cutaway view.

This structure (see figure 1) is made up of curb girder (1), front end fixed head (2), several turnover panels (3), rear end fixed head (4), active pin shaft (5), connecting rod parts such as (6).

The turnover panel structure is seen Fig. 3, and there is rotating shaft (7) at its two ends, and there is pull bar lug (8) at a back.

This architectural feature is several turnover panels (3), and turnover panel two ends rotating shaft (7) and two curb girders (1) are hinged, and back of turnover panel has pull bar lug (8), and is hinged by bearing pin (5) and connecting rod (6).Wherein several turnover panels (3) are the critical pieces of this structure, it is characterized in that each turnover panel cross section is L-shaped, and the narrow one side of each turnover panel is jagged for ventilation, and breach quantity can have one or several.

When burning, all several turnover panels (3) all are in the overlap joint state, see Fig. 1, to prevent leakage under solid waste and the raffinate.And front end fixed head (2) and rear end fixed head (4) are set prevent to leak under the rear and front end, two curb girder cross sections take the shape of the letter U and also can prevent leakage both sides solid waste and raffinate under.

In the time of need stirring solid waste, only need spur pull bar (6) a little,, finish several turnover panels (3) and stir simultaneously, reach the purpose of stirring solid waste by parallel double crank mechanism interlock effect.

Burn when finishing, only need pulling pull bar (6) to extreme position, see Fig. 4, by parallel double crank mechanism interlock effect, make all perks fully of several turnover panels (3), two adjacent turnover panel gaps increase to maximum, to reach the deashing purpose.

Claims

1. incineration furnace grate of forming by several turnover panels (3), curb girder (1), connecting rod (6), active pin shaft (5) etc., it is characterized in that several turnover panels (3) two ends rotating shafts (7) and two curb girders (1) are hinged, and back of turnover panel has pull bar lug (8), and is hinged by active pin shaft (5) and connecting rod (6).

2. several turnover panels of incineration furnace grate according to claim 1 (3) is characterized in that each turnover panel cross section is L-shaped.

3. several turnover panels of incineration furnace grate according to claim 1 and 2 (3) is characterized in that the narrow one side of each turnover panel is jagged.
