Abstract
The utility model discloses a kind of combustion furnace and assist air channel, comprise burner hearth, described burner hearth comprises upper furnace and lower hearth, be fixedly connected with by flange between described upper furnace and lower hearth, burner hearth inside is provided with ventilating board in the position of Flange joint, ventilating board is evenly equipped with air vent, bypass pipe is provided with between the outside of upper furnace and the outside of lower hearth, bypass pipe is provided with two, be symmetrically set in the both sides of burner hearth, described bypass pipe comprises the upper pipe be interconnected, intervalve and lower pipe, the lower end being close to flange is located at by lower pipe, the top of flange is located at by upper pipe, be welded and fixed between upper pipe and upper furnace, to be welded and fixed between pipe and lower hearth down.The advantage that the utility model has and good effect are: adopt auxiliary air channel, can make to ventilate in combustion furnace more smooth and easy, and can prevent ventilates has some setbacks and the furnace sandwich that causes builds the pressure, prolonging combustion stove service life, make oxygenating more abundant, are beneficial to burning.
Description
Technical field
The utility model belongs to burner installation field, especially relates to a kind of combustion furnace and assists air channel.
Background technology
Combustion furnace generally passes through delivering oxygen from top to bottom, realizes upper and lower homogenous combustion.Flange layer in prior art in combustion furnace is evenly equipped with logical oxygen hole, oxygen from logical oxygen hole upwards delivering oxygen, but due to logical oxygen hole less, often ventilate and have some setbacks, furnace sandwich can be caused to build the pressure, decay combustion furnace service life.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of combustion furnace and assists air channel, can solve the problem.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: air channel assisted by a kind of combustion furnace, comprise burner hearth, described burner hearth comprises upper furnace and lower hearth, be fixedly connected with by flange between described upper furnace and lower hearth, burner hearth inside is provided with ventilating board in the position of Flange joint, ventilating board is evenly equipped with air vent, bypass pipe is provided with between the outside of upper furnace and the outside of lower hearth, bypass pipe is provided with two, be symmetrically set in the both sides of burner hearth, described bypass pipe comprises the upper pipe be interconnected, intervalve and lower pipe, the lower end being close to flange is located at by lower pipe, the top of flange is located at by upper pipe, be welded and fixed between upper pipe and upper furnace, to be welded and fixed between pipe and lower hearth down.
Further, described upper pipe and lower pipe are parallel to each other, intervalve perpendicular to upper pipe, upper pipe, between intervalve and lower pipe by being welded and fixed.
Further, the length of described intervalve is 2.5 times of upper length of tube.
Further, described bypass pipe is stainless steel.The service life of bypass pipe can be extended.
The advantage that the utility model has and good effect are: adopt auxiliary air channel, can make to ventilate in combustion furnace more smooth and easy, and can prevent ventilates has some setbacks and the furnace sandwich that causes builds the pressure, prolonging combustion stove service life, make oxygenating more abundant, are beneficial to burning.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of described ventilating board;
Description of reference numerals:
1-upper furnace; 2-lower hearth; 3-flange; 4-ventilating board; 5-air vent; The upper pipe of 6-; 7-intervalve; Manage under 8-.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As Fig. 1, shown in 2, air channel assisted by a kind of combustion furnace, comprise burner hearth, burner hearth comprises upper furnace 1 and lower hearth 2, be fixedly connected with by flange 3 between upper furnace 1 and lower hearth 2, the inner position connected at flange 3 of burner hearth is provided with ventilating board 4, ventilating board 4 is evenly equipped with air vent 5, bypass pipe is provided with between the outside of upper furnace 1 and the outside of lower hearth 2, bypass pipe is provided with two, be symmetrically set in the both sides of burner hearth, described bypass pipe comprises the upper pipe 6 be interconnected, intervalve 7 and lower pipe 8, the lower end being close to flange 3 is located at by lower pipe 8, the top of flange 3 is located at by upper pipe 6, be welded and fixed between upper pipe 6 and upper furnace 1, be welded and fixed between lower pipe 8 and lower hearth 2.
Upper pipe 6 and lower pipe 8 are parallel to each other, intervalve 7 perpendicular to upper pipe 6, upper pipe 6, between intervalve 7 and lower pipe 8 by being welded and fixed.
The length of intervalve 7 is 2.5 times of upper pipe 6 length.
Bypass pipe is stainless steel.The service life of bypass pipe can be extended.
During use, oxygen infusion is on ventilating board 4, because air vent 5 easily blocks, ventilation has some setbacks, and oxygen can flow to bypass pipe along ventilating board 4, and oxygen is flow to upper furnace 1 from lower hearth 2 by bypass pipe, can prevent ventilates has some setbacks and the furnace sandwich caused builds the pressure, prolonging combustion stove service life, make oxygenating more abundant, be beneficial to burning.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
