Description
Technical field
The utility model belongs to technical field of burner, is specifically related to the used new and effective coal powder burner of a kind of road building business.
Background technology
At present, China has multiple at the used burner of road building business basically, comparatively just general with combustion gas (natural gas) burner, oil burner and coal burner, gas burner is subjected to the restriction of local resources, can't use in the place without natural gas, day by day soaring along with fuel price, coal burner is more popular with users with convenient, the cheap use cost of its buying.Existing coal powder burner is comprised of coal pulverizer, conveying coal pipe, burner, oil-firing system and several parts of control system on the market.Ignite before this burner operation, need manually with torch fuel oil to be lighted, the fuel oil coal dust that ignites, because the ature of coal difference of China various places is larger, uses the manual firing, ignition success rate is lower, danger is higher simultaneously, and often appearance need to repeatedly light a torch, and operates extremely inconvenient.And easily cause localized burn in the existing coal burner use procedure, the burner hearth life-span is short, burns insufficient, and flame partially fire is serious, the scarfing cinder difficulty, and slagging scorification is serious.For solving the problem of local slagging scorification scaling loss, burner hearth adopts the mode of rotation to avoid local long-time heat damage, but the basic reasons of its slagging scorification scaling loss is ventilation to be arranged unreasonable, coal dust firing is insufficient, flame appearance skew causes, and the mode that only changes the rotation burner hearth can not fundamentally solve the problem of slagging scorification scaling loss.
Summary of the invention
The defects that exists for solving prior art, the purpose of this utility model is to provide a kind of compact conformation, and coal dust firing is abundant, and ature of coal adaptability is good, long service life, igniting is new and effective coal powder burner easily.
For achieving the above object, the technical solution adopted in the utility model: this new and effective coal powder burner, has underframe, burner hearth, stable burning room, wind powder governor motion, blower fan, igniter and electric control system, burner hearth places on the underframe, stable burning room's part embeds in the hearth body, stable burning room connects wind powder governor motion and igniter, it is characterized in that: described wind powder governor motion inwardly is provided with outer direct current air channel successively from skin, eddy flow wind passage, interior direct current air channel, coal dust air channel and central tube, blower fan and above-mentioned outer direct current air channel, eddy flow wind passage and interior direct current air channel are connected; The port of export in described outer direct current air channel is provided with the direct current blade of long distance, be provided with the wide-angle swirl vane that the wind rotation is blown out in the described eddy flow air channel, the exit position in described interior direct current air channel evenly is provided with a plurality of direct current blades, described central tube is taper in the exit position, described coal dust ducting outlet evenly arranges a plurality of camber blades, the taper of the inner edge of described camber blades and central tube end coincide, described central tube is positioned at the center in coal dust air channel, and pass the coal dust air channel, can be radially mobile in the coal dust air channel.
The port of export in described coal dust air channel has the air outlet of taper contraction section, straight length and toroidal.
Described stable burning room, wind powder governor motion and blower fan are fixed on the moving frame, and the bottom of moving frame is provided with road wheel, and road wheel is placed in the track on the underframe, and the driving mechanism ground-engaging wheel moves forward and backward.
Described burner hearth is provided with rotating driving device, and described rotating driving device has two rolling rings that are positioned on the hearth housing and the idler pulley that supports rolling ring, and each rolling ring is supported by two idler pulleies, and driving mechanism drives the idler pulley rotation.
Adopt the beneficial effect of technique scheme: the port of export in the outer direct current air channel of this new and effective coal powder burner is provided with the direct current blade of long distance, form powerful direct current wind at inboard wall of burner hearth, can retrain the diffusion of flame, reduce the temperature of inboard wall of burner hearth, avoid flame scaling loss inboard wall of burner hearth, the slag that produces in the burner hearth can be blown out burner hearth, avoid slag to be bonded on the inboard wall of burner hearth, prolong the service life of burner hearth.Be provided with the wide-angle swirl vane that the wind rotation is blown out in the described eddy flow air channel, be formed centrally the recirculating zone of coal dust firing in the wind of High Rotation Speed, regulate simultaneously the air quantity in outer direct current air channel, interior direct current air channel and coal dust air channel according to the quality of ature of coal, can expand or reduce diameter and the length of recirculating zone, adapt to from the low multiple ature of coal of assigning to high volatile of waving.When the burning high-volatile bituminous coal, increase the wind speed in outer direct current air channel, with the length of compression recirculating zone, suitably reduce the eddy flow air channel volume, direct current air channel flow in strengthening makes flame reach best steady combustion state and makes second-time burning more abundant, and has kept the best length of flame; Low when waving minute bituminous coal or anthracite when using, reduce outer direct current air channel volume, to expand diameter and the length of recirculating zone, increase the eddy flow air channel volume, reduce interior direct current air channel volume, make flame reach best steady combustion state, burn more abundant, and keep the best length of flame.Described coal dust ducting outlet evenly arranges a plurality of camber blades, and the rotation of coal dust wind makes coal dust can fully mix with air, and central tube can be radially mobile in the coal dust air channel, quality according to ature of coal, regulate central tube and camber blades fit clearance, the length that also can regulate flame, igniting is convenient.The stable burning room bottom is provided with walking mechanism, the length of flame during according to coal dust firing, can regulate stable burning room and stretch into the length of burner hearth, be equivalent to increase the combustion space of burner hearth, make burning more abundant, thereby reduced the formation of slag, and slag is light and soft shape, and powerful outer direct current wind can directly blow out burner hearth with the slag ash, can not form the phenomenon of slag bonding burner hearth, even a small amount of slag is arranged, cleaning is also convenient.The port of export in described coal dust air channel has the air outlet of taper contraction section, straight length and toroidal, has similar Venturi tube structure, coal dust is mixed more even with air, is beneficial to abundant burning.Therefore compared with prior art, have compact conformation, coal dust firing is abundant, and ature of coal adaptability is good, long service life, and the easily characteristics of lighting a fire can satisfy the various heat requests that add in the road building business.
