Abstract

A gang screw coal feed combustion apparatus belongs to the technical field of combustion heating equipments. A furnace grate comprises a plurality of mutually contactless screw poles which can be driven to rotate. One ends of a plurality of screw poles are stretched out of a furnace body from a furnace door, and the ends can be connected with a speed reduction motor. During combustion heating, lump coal, crushed coal or coal ash mud is placed on the part of the furnace grate which is stretched out of the furnace body from the furnace door. After the screw poles composing the furnace grate rotates, under the push of the spiral matters on the screw poles, solid fuel is gradually fed onto the furnace grate inside the furnace from the furnace door and burns inside the furnace. The rotary screw poles are difficult to have coal scale, which helps the coal cinder, coal scale and coal ash fall into an ash falling chamber. As a coal conveying mechanism and a waste clearance mechanism are ingeniously integrated with the furnace grate, the utility model has the advantages of simple structure, low manufacturing cost, uniform coal feeding, no coal jam, convenient operation, great labor intensity reducing and clean environment keeping.

Description

Grate type helical coal feeding and burning device

Technical field

The utility model belongs to the burning heating equipment technical field.

Background technology

The burning heater that with the coal is fuel is widely used in each industrial circle, as is used for tobacco first baking, food processing etc.The body of heater of such burner comprises the burner hearth of fire door, grate, grate top and the ash-falling chamber of grate below, and wherein grate is made of parallel or crossing trellised many fixed grates.During heating flame, the workman needs with instruments such as scoops lump coal, broken coal or coal ash mud to be held in fire door is sent into stove on the grate, and adds coal-fired frequently and dredge with instruments such as cleeks and disclose grate, to remove coal ash, cinder, coal dirt.Big and the many contaminated environment of flying dust of existing apparatus labour intensity.

The utility model content

The purpose of this utility model provides a kind of grate type helical coal feeding and burning device, and is not only simple in structure, and easy to use, labour intensity is little, clean environment firendly.

The body of heater of the utility model device comprises the burner hearth of fire door, grate, grate top and the ash-falling chamber of grate below, it is characterized in that: grate is made of many that the are not in contact with one another screw rods that can drive rotation, and an end of said many screw rods stretches out outside the body of heater from fire door.

Many screw rods can be connected with the rotating interlock plate of a band handle from the end that fire door stretches out outside the body of heater, turning handle just can rotate whole screw rods by interlock plate, but the utility model device preferred construction is that many screw rods are stretched out end and reducing motor driving coupling outside the body of heater from fire door.Can be end and a reducing motor driving coupling of each root screw rod, also can be the end and a more powerful reducing motor driving coupling of whole screw rods.Reducing motor can adopt direct current or alternating current generator, and rotating speed is preferably per minute 15～30 to be changeed.

If the hand of spiral of the screw rod of a side is opposite with the hand of spiral of the screw rod of opposite side in the grate, can avoid like this that coal gathers partially on grate one side in the defeated coal process.

The utility model device when heating burning, lump coal, broken coal or coal ash mud are held on above that part of outside fire door stretches out body of heater of grate.After constituting the screw rod rotation of grate, under the promotion of spiral thing on the screw rod, solid fuel is just sent into above the grate of furnace interior branch, in the stove internal combustion gradually through fire door.The screw rod of rotation also is difficult for knot coal dirt, helps cinder, coal dirt, coal ash to fall into ash-falling chamber.If all the other end of screw rods also stretches out from a back door of body of heater outside the body of heater to a slag removing chamber, outside the combustion residue release body of heater that then Xuan Zhuan screw rod can also be bigger with cinder, coal dirt etc. and fall into slag removing chamber.According to the needs of use occasion and heating process, screw rod can intermittently rotate, and also can rotate continuously.For example if the utility model device is used for the tobacco first baking room, then screw rod can rotate 1～2 minute, stopped a period of time then and rotated, so repeatedly operation.

Coal conveyor structure in the burner, waste material are removed mechanism to the utility model and grate is fused into one dexterously, have low cost of manufacture simple in structure, deliver coal evenly, can not block coal, easy to use, reduce labor intensity and advantage such as clean environment firendly greatly.

The specific embodiment

See following examples.

Embodiment 1: see Fig. 1～3.This device is used for the tobacco first baking room.Body of heater comprises the burner hearth 2 of fire door 1, grate, grate top and the ash-falling chamber 3 of grate below.Said grate is made of 8 screw rods 4 that can drive rotation of level and equidistant parallel.All an end of screw rods 4 stretches out outside the body of heater from fire door 1, and the other end stretches out from the back door 5 of body of heater outside the body of heater to slag removing chamber 6.The end of every screw rod 4 is each and 6V DC speed-reducing 7 driving coupling (not expression respectively among the figure) respectively.Grate is provided with coal bunker 8 from the top that fire door 1 stretches out outside the body of heater.9 is side shield among the figure, and 10 is bottom baffle.8 screw rods 4 are arranged in the plane.In the grate side hand of spiral and the opposite side of totally 4 screw rods 4 hand of spiral of totally 4 screw rods 4 is opposite, can avoid like this that coal gathers at grate on one side partially in the defeated coal process.

Embodiment 2: see Fig. 4, screw rod 11 is arranged in the cancave cambered surface, and all the other are with embodiment 1.
