Description
Technical field
The utility model relates to a kind of dismountable Wind cap for boiler, belongs to boiler combustion device field.
Background technology
Wind cap for boiler is arranged on the aerofoil of fluidized-bed combustion boiler bottom of combustion chamber, inside communicates with bellows, purposes is transported in the siege bed of material by boiler air-supply, air required when meeting boiler, by controlling the size of air output, be that the siege bed of material remains fluid boiling state, make coal burning thorough.But the damage that such structure is easy to make to block tiny meagre profit in the space of air-supply and causes Wind cap for boiler, also there is a lot of drawback in the structure of integration, develops demountable blast cap in time in the market, but still there is its disadvantage.Therefore, a kind of new technical scheme should be provided to solve the problem.
Summary of the invention
The utility model provides a kind of dismountable Wind cap for boiler.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of dismountable Wind cap for boiler, comprise blast pipe, blast cap outer cover and air vent, blast pipe is placed on the inside of blast cap outer cover, the upper end of blast pipe is provided with air vent, the inside of blast cap outer cover is provided with blast pipe, the connection, lower end of the centre of blast pipe and the inner side of blast cap outer cover is equipped with the screw thread of coupling mutually, and the lower end cover of the screw thread on blast pipe has sealing ring.
The related content of technique scheme is explained as follows:
In such scheme, the air vent that blast pipe upper end is provided with is two-row structure, and in cross-distribution.
In such scheme, the top of the blast pipe be provided with in blast cap outer cover is provided with gas storage groove, and gas storage groove is hemispherical.
Preferably, sealing ring is stainless steel wire metal o-ring.
Because technique scheme is used, the utility model compared with prior art has following advantages:
Because the utility model compact conformation is simple, utilize screw thread and sealing ring blast pipe and blast cap outer cover to be combined closely, convenient disassembly, adopt stainless steel wire to be the metal o-ring of material, sealing effectiveness is very excellent; Air vent is the two-row structure of cross-distribution, wind can be disperseed, and prevents the excessive damage caused device of air quantity; Be provided with hemispheric gas storage groove in the upper end of blast pipe, be also that component is excessive, too fast causes damage to device in order to prevent, play the effect of transition.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model schematic diagram.
In above accompanying drawing: 1, blast cap outer cover; 2, gas storage groove; 3, blast pipe; 4, screw thread; 5, blast pipe, 6, air vent, 7, sealing ring.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
As shown in Figure 1, a kind of dismountable Wind cap for boiler, comprise blast pipe 5, blast cap outer cover 1 and air vent 6, blast pipe 5 is placed on the inside of blast cap outer cover 1, the upper end of blast pipe 5 is provided with air vent 6, the inside of blast cap outer cover 1 is provided with blast pipe 3, the connection, lower end of the centre of blast pipe 5 and the inner side of blast cap outer cover 1 is equipped with the screw thread 4 of coupling mutually, the lower end cover of the screw thread 4 on blast pipe 5 has sealing ring 7, the air vent 6 that blast pipe 5 upper end is provided with is two-row structure, and in cross-distribution, the top of the blast pipe 3 be provided with in blast cap outer cover 1 is provided with gas storage groove 2, gas storage groove 2 is hemispherical.
Preferably, sealing ring 5 is stainless steel wire metal o-ring.
The utility model compact conformation is simple, and utilize screw thread 4 and sealing ring 7 blast pipe 5 and blast cap outer cover 1 to be combined closely, convenient disassembly, adopt stainless steel wire to be the metal o-ring of material, sealing effectiveness is very excellent; Air vent 6 is the two-row structure of cross-distribution, wind can be disperseed, and prevents the excessive damage caused device of air quantity; Be provided with hemispheric gas storage groove 2 in the upper end of blast pipe 3, be also that component is excessive, too fast causes damage to device in order to prevent, play the effect of transition.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
