Description
Technical field
The utility model is related to the air-cooled nozzle of boiler sand dust, especially suitable for being used during Fibreboard Production.
Background technology
In present Fibreboard Production process, generated sand dust can be used as biomass to provide boiler auxiliary fuel and use,
Sand dust sprays into Boiler Furnace chamber inner combustion by sand dust nozzle, but existing sand dust nozzle is using water-cooling pattern, the high temperature foot in boiler
To burn out the water cooling jacket wall of stainless steel, lead to leak, be unable to reach the effect of cooling, moreover, the sand dust of ejection is in stove
Chamber inner combustion is insufficient, and utilization rate is low.
The patent No. 201410695783X that State Patent Office authorizes discloses a kind of high temperature resistant feed nozzle, and feature exists
In：Its composition includes：Nozzle, it is characterised in that：The nozzle is connect with connecting flange, the connecting flange respectively with it is additional
Jacket water inlet duct, outer layer oxygen intake pipeline, nozzle head cooling water inlet pipeline, nozzle head cooling water outlet pipe
Road, the connection of external jacket cooling water outlet pipeline, the external jacket cooling water outlet pipeline pass through connecting flange and material inlet
Pipeline connects, and the material inlet pipeline is gone out by connecting flange respectively at internal layer cooling water inlet pipeline, internal layer cooling water
Mouth pipeline connection, the internal layer cooling water outlet pipeline are connect with central oxygen inlet duct, and deficiency is that this structure is still led to
It crosses water cycle and realizes from inside and carry out cooling heat dissipation to nozzle, be used for a long time easily leakage, when maintenance is time-consuming, influences to produce.
Invention content
The task of the utility model is to propose a kind of sand dust nozzle keep away from boiler burner hearth, good cooling results, and service life is long
The air-cooled nozzle of boiler sand dust.
The task of the utility model be done in such a way that it is characterized in that：Pipeline, pipeline external port peace are embedded in burner hearth
Equipped with flange, flange is fixed with the installation of sand dust nozzle, and the sand dust nozzle is made of air-cooled set, spiral spout, helical blade, institute
It states and is provided with air-cooled set outside spiral spout, helical blade is uniformly installed in air-cooled set, air-cooled set is docked with the Single port of air compartment,
The other end of air compartment is connected by pipeline with wind turbine, and blade is equipped in spiral spout, and sand dust nozzle input terminal is equipped with sand
Dirt delivery pipe is docked with feed bin.Blade lean is installed.It is installed in the helical blade and spiral spout installed in the air-cooled set
Blade direction of rotation it is opposite.
The utility model has the following effects that：The technical program saves existing water cooling mode structure, using wind turbine
Sand dust is conveyed into burner hearth from the spiral spout of jet pipe front end with air compartment, therefore the service life of sand dust jet pipe can be extended, so as to drop
Low production cost.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；Fig. 2 is the vertical view of spiral spout；Fig. 3 is the structure of spiral spray pipe
Schematic diagram.
Drawing explanation：1st, pipeline, 2, air-cooled set, 3, burner hearth, 4, spiral spout, 5, helical blade, 6, flange, 7, sand dust it is defeated
Send pipe, 8, air compartment, 9, wind turbine, 10, blade.
Specific embodiment
Embodiment is described in detail with reference to the figures above, as depicted in figs. 1 and 2, pipeline, 1 outer end of pipeline are embedded in burner hearth 3
Mouth is equipped with flange 6, and flange is fixed with the installation of sand dust nozzle, and the sand dust nozzle is by air-cooled set 2, spiral spout 4, helical blade
5 are formed, and air-cooled set 2 is provided with outside the spiral spout, and helical blade 5, air-cooled set and air compartment 8 are uniformly equipped in air-cooled set 2
Single port docking, the other end of air compartment is connected, and blade 10 is equipped in spiral spout by pipeline 1 with wind turbine 9, and blade inclines
Tiltedly installation, sand dust nozzle input terminal are equipped with sand dust delivery pipe 7 and are docked with feed bin, and wind turbine is by wind through pipeline to air compartment, wind
Wind in room is blown out by being acted on Sloped rotating by helical blade 5 after air-cooled set 2.
The blade direction of rotation installed in the helical blade and spiral spout installed in the air-cooled set is opposite.
The helical blade quantity is preferably 8, and blade preferred amount is 4.
It can to sum up obtain, the utility model is by being provided with air-cooled set 2, spiral spout 4, helical blade 5, air compartment 8, wind turbine 9
With blade 10, the shortcomings that prior art sand dust nozzle external application water(-cooling) jacket cools down is overcome, easily makes to burn out cooling jacket wall, causes to leak
Water, shut-down are replaced, are wasted time, influencing the problem of manufacturing schedule.
During work, the sand dust in feed bin inputs sand dust nozzle, and when by spiral spout via sand dust conveyance conduit, by
The dihedral vane effect uniformly installed in spiral spout, along inclined direction rotation spray.Meanwhile wind is blasted air compartment by wind turbine, and
By being acted on after air-cooled set by the helical blade uniformly installed in air-cooled set, along inclined direction blow out.It is sprayed out of spiral spout
Sand dust and the wind that is blown out out of air-cooled set due to direction on the contrary, more fully burning in burner hearth is sprayed into after being sufficiently mixed.
