Description
Technical field
The utility model belongs to boiler drying technology field more particularly to a kind of hot-air drying unit for boiler.
Background technique
Boiler is a kind of various fuel of utilization, electricity or other energy, and the liquid contained is heated to certain parameter, and
The externally equipment of output thermal energy.Modern industry boiler is usually provided with insulating layer inside it, for preventing scattering and disappearing for heat, but
Be that in the long-term use, insulating layer will appear cracking etc., need shutdown maintenance, built again on the insulating layer of boiler or
It after casting, needs to dry insulating layer, traditional drying mode is to protrude into boiler internal by combustor, then igniting pair
The insulating layer of boiler is dried, but since boiler is usually higher, this drying is simultaneously not thorough, nor uniformly.
Summary of the invention
In order to solve the problems in the existing technology, the purpose of the utility model is to provide a kind of hot winds for boiler
Drying unit.
In order to achieve the above-mentioned object of the invention, the utility model uses technical solution as described below:
A kind of hot-air drying unit for boiler, including blower and air duct, the air duct inside are equipped with wind pipe, wind
Cylinder and wind pipe are the hollow structure of open at both ends, and the left port of air duct is sealed by end plate, the wind pipe left end
It is provided with left annular seal plate on the outer surface of mouth, the periphery of the left annular seal plate is fixedly connected on the inner surface of air duct
On, a cavity is formed between left annular seal plate and the end plate, the left annular seal plate is equipped with several ventilation holes, air duct
Other port be provided with right annular seal plate, the inner headed face of right annular seal plate is fixedly connected on the surface of wind pipe
On, position is equipped with the mounting hole for installing burning oil gun among the air duct outer surface, and air duct outer surface front end is set
There is a connecting hole, the air outlet of the blower is connected by pipeline with connecting hole.
Further, the central axis of the wind pipe and air duct is located along the same line.
Further, the length of the wind pipe is greater than the length of air duct.
Further, the air duct and wind pipe are metal material.
Further, the mounting hole is located at the right side of left annular seal plate.
Due to the adoption of the above technical scheme, the utility model has following superiority:
When the utility model is used, the right output port of wind pipe is protruded into along boiler bottom, and by the oil gun of combustor
The mounting hole on air duct is protruded into, starts combustor and blower, circular passage of the wind between the wind pipe of air duct is moved to a left side
Annular seal plate, wind are heated when passing through oil gun, and the hot ventilation hole after heating enters cavity, and then hot wind is again along wind pipe stream
It is dynamic, and have port blowout from wind pipe, hot wind flows from bottom to top along boiler insulation layer, so that insulating layer can be heated
More uniformly, so that drying effect greatly improves.

Specific embodiment
The technical solution of the utility model is described in further detail with reference to the accompanying drawings and embodiments.
As shown in Figure 1, 2, a kind of hot-air drying unit for boiler, including blower 1 and air duct 2, inside the air duct 2
Equipped with wind pipe 3, air duct 2 and wind pipe 3 are the hollow structure of open at both ends, and the left port of air duct 2 is close by end plate 9
It seals, is provided with left annular seal plate 6, the periphery of the left annular seal plate 6 on the outer surface of 3 left port of wind pipe
It is fixedly connected on the inner surface of air duct 2, forms a cavity between left annular seal plate 6 and the end plate 9, the left annular is close
Sealing plate 6 is equipped with several ventilation holes 8, and the other port of air duct 2 is provided with right annular seal plate 4, right annular seal plate 4 it is interior
Disc is fixedly connected on the surface of wind pipe 3, and position is equipped with for installing burning oil gun among 2 outer surface of air duct
Mounting hole 5, the 2 outer surface front end of air duct is equipped with a connecting hole 7, and the air outlet of the blower 1 passes through pipeline and connecting hole 7
It is connected.
The central axis of the wind pipe 3 and air duct 2 is located along the same line.
The length of the wind pipe 3 is greater than the length of air duct.
The air duct 2 and wind pipe 3 are metal material.
The mounting hole 5 is located at the right side of left annular seal plate.
When the utility model is used, the right output port of wind pipe is protruded into along boiler bottom, and by the oil gun of combustor
The mounting hole on air duct is protruded into, starts combustor and blower, circular passage of the wind between the wind pipe of air duct is moved to a left side
Annular seal plate, wind are heated when passing through oil gun, and the hot ventilation hole after heating enters cavity, and then hot wind is again along wind pipe stream
It is dynamic, and have port blowout from wind pipe, hot wind flows from bottom to top along boiler insulation layer, so that insulating layer can be heated
More uniformly, so that drying effect greatly improves.
