Abstract

The utility model relates to a moveable squeezing into type coal feeder, which relates to the coal supply device of the coal-burning equipment with fixing grates and stokers. The existing manual coal feeding and smoke removing technique effects are different owing to different people and are difficult to stabilize; a fixing coal feeder is arranged on the front part of a furnace, and the stoker operation can be influenced. The utility model uses the moveable feeder to squeeze the coal into the middle part of a fuel bed, and thus, the liberation velocity of the volatile matter of the coal can be controlled under the condition of limited heating. Besides, the coal can firstly combust in reverse under the covering of a burning red coal bed, and then, the coal can obtain conventional positive combustion. When anyone presses a button, the utility model can realize coal feeding without black smoke; besides, the utility model has stabler and more reliable effect matching with kiln improvement. After coal feeding, the utility model is also convenient for conventional stoking operations of prying the fire, poking the ash, stabilizing the furnace, discharging the slag, etc. The utility model is mainly used for technical improvement of smoke removal of industrial furnaces. A plurality of coal feeding openings can share one coal feeder, and thus, the utility model has the advantages of very little equipment investment and running cost. In generally, the user can earn the investment for about half year.

Description

Removable extruding type firing machine

(1), technical field: the utility model relates to the coal supply device of the manual stoker's of fixed grate coal combustion equipment.The fuel supply field that belongs to combustion apparatus.

(2), background technology: China has millions of handwarmer kilns (manual stoker's stove) now, under the pressure of the pressure of environmental protection, for solving a coal paroxysmal black smoke difficult problem that causes because of " grate firing vicious circle cycle ", occurs many technical schemes in recent years.Such as: " no black smoke hand throw coal Industrial Stoves (ZL96220513.3) " but oke exhaust blackness Da Lingeman O level but be difficult to stablize because of the quality of fireman's operation; Many firing machines based on artificial stoker also appearred.But because of it is fixedly mounted on the stokehold, influence sled fire, open hearth, ash poking, stoker such as slag tap operate and are difficult to keep normal combustion.

(3), summary of the invention: the utility model is bigger at the human factor influence that hand burns, and fixedly firing machine then influences problem such as stoker's operation and the new solution that proposes.It is characterized in that: firing machine can move.

The utility model is than the beneficial effect of prior art: anyone can realize not having the black smoke coal once pressing a button.This firing machine can be removed behind the coal, and the fireman can prize fire, open hearth, ash poking as before easily and stoker's operation such as slag tap.

(4), the specific embodiment: will push coal and be mechanically anchored on the dolly, dolly can move on smooth ground or track.The transmission mechanism of firing machine can adopt machine driving and belt transmission, when adopting hydraulic pressure or strength transmission, forcing press can also be separated with propelling movement coal mechanism, only moves a propelling movement coal mechanism and gets final product.Propulsive thrust with respect to pushing coal is provided with level or tilting back brace behind the machine.By the back brace that can stretch or can fold, back thrust is guided in firm back wall or the ad hoc back stake.Artificial or through the coal hopper gate, coal is put in the firing machine.Press push button, the push rod on the machine drives to cut somebody's hair coal is advanced in the stove.When coal is got at the middle part of fuel bed side, the coal of newly getting into becomes a whole group that is clipped in the fuel bed centre.Because of above have the red carbon layer that is burning topped, the coal of newly adding is heated by the top and the conduction of side red carbon layer mainly, from outward appearance to inner essence successively is heated and the fugitive constituent that progressively discharges, must pass through red carbon layer and just can enter furnace cavity.When the fugitive constituent of coal passes, under conditions such as high temperature, sufficient oxygen, stirring and time enough, be easy to realize the completing combustion of flame, thereby avoided the generation of black smoke that it is more reliable and stable that cooperation changes its effect of kiln from the slit of red charcoal piece.Got rid of the influence of human factor to oke exhaust blackness; Coal advances the position of burner hearth to may be selected in the facade space that fire grate is above, coal filling hole is following, and a special-purpose coal feed point that has the fire grate function when matching with the firing machine outlet also can newly be installed.Stoker's operations such as firing machine is removed after adding coal, and the fireman can carry out conventional sled fire, open hearth, ash poking, slag tap.When coal feed point is arranged on the stove side or the back side, but also can set up the door of switch on the mouth.

Enter the explanation in step in conjunction with the accompanying drawings: accompanying drawing is removable extruding type firing machine and coal schematic diagram.Push coal mechanism and be installed on the cabinet 5, cabinet is equipped with wheel 65 times; The back thrust that produces when pushing coal passes to the back wall by back brace 4 or the back pile is subjected to.Coal is through being subjected to coal bunker 1 to enter firing machine, after starting push button, push rod 3 with cut somebody's hair 2 forward impelling, coal is got into the position of fuel bed middle part coal 8 in the stove firmly, have red carbon layer 7 topped above, utilize the anti-principle of burning to realize black-smoke free combustion.Cinder 9 after burning is discharged through the slit of fire grate 10.

Claims

1, a kind of removable extruding type firing machine is subjected to coal bunker, transmission mechanism, propelling movement coal mechanism, and it is characterized in that: the firing machine bottom is equipped with the wheel that can roll;

2, removable extruding type firing machine as claimed in claim 1 is characterized in that: can the whole machine installation wheel, or power section fixed, only wheel partly is installed pushing coal mechanism;

3, removable extruding type firing machine as claimed in claim 1 is characterized in that: transmission mechanism is hydraulic drive or strength transmission, also can be machine driving and belt transmission;

4, removable extruding type firing machine as claimed in claim 1 is characterized in that: coal is pushed the into position of burner hearth, a coal feed point that matches with the firing machine outlet can or newly be installed in the facade space between fire door and the fire grate.
