Description
Technical field
The utility model relates to a kind of device of chemical fertilizer production, and particularly a kind of hot-blast stove can completely cut off the combined hot airduct of flame.
Background technology
Hot-blast stove is by the device of blast heating to required temperature, and its advantage is that heat-exchange temperature is high, and heat utilization efficiency is high, is widely used in the preparation of chemical products and medicine and dry field.But there is following shortcoming in the application in hot-blast stove at present, after hot-blast stove is temperature required to Drying by air heat in combustion chamber, flame in combustion chamber can enter into Drying together along with hot-air (hot blast), this flame can by chemical fertilizer production material melting, equipment is cohered, time has been grown and can cause heavy corrosion to feed opening, causes burner stove tail excessive temperature differentials, affects production quality and the production efficiency of product.
Summary of the invention
The purpose of this utility model is, provides a kind of hot-blast stove can completely cut off the combined hot airduct of flame.The utility model has isolated flame, avoids flame that material is dissolved, and avoids material to stick on equipment, avoids equipment corrosion and avoids burner stove tail excessive temperature differentials to improve product quality, production efficiency and maintain easily the feature of cleaning.
The technical solution of the utility model: a kind of hot-blast stove can completely cut off the combined hot airduct of flame, comprises the first main body, and the first main body is connected with the second main body; The inwall of the first described main body is provided with the first fireguard, and the outer wall of the first main body is provided with the first link slot, and the outer wall of the first main body is also provided with the first contiguous block; The inwall of the second described main body is provided with the second fireguard, and the outer wall of the second main body is provided with the second link slot, and the outer wall of the second main body is also provided with the second contiguous block; The first described link slot is connected with the second contiguous block, and the first contiguous block is connected with the second link slot; The first described fireguard and the second fireguard are dislocatedly distributed; The first described fireguard and the second fireguard are all in foliaceous.
Aforesaid hot-blast stove can completely cut off in the combined hot airduct of flame, and the first air intake diameter of the first described main body is greater than the first outlet air end diameter; Second air intake diameter of the second described main body is greater than the second outlet air end diameter.
Compared with prior art, the utility model is respectively equipped with the first fireguard and the second fireguard in first main body and the second main body inner wall of warm-air pipe, and the first fireguard and the second fireguard are dislocatedly distributed, the cavity of the warm-air pipe of the first main body and the second main body composition is made to be divided into the space of folding shape, flame along with hot blast folding shape space in flow, flame is constantly blocked by fireguard, consumes in this process, until flame is blocked completely, consumes; By the effectively isolated flame of this structure, avoiding flame to enter and make material melting in Drying and cohere on equipment and then make equipment corrosion, avoiding the situation affecting the quality of product because corroding the burner stove tail excessive temperature differentials that causes simultaneously.Fireguard is arranged to the curved surface of blade type by the utility model, and hot blast is reduced in the flow resistance of warm-air pipe; The diameter of the first air intake and the second air intake is set to the diameter being greater than the first outlet air end and the second outlet air end simultaneously, thus make the diameter of the air inlet of warm-air pipe (being combined by the first air intake and the second air intake) be greater than the diameter of air outlet (being combined by the first outlet air end and the second outlet air end), hot blast is allowed to form draught head at air inlet and air outlet, cause hot blast flow velocity faster, to this increase the drying efficiency of product, thus enhance productivity.Warm-air pipe is divided into the first main body and the second main body by the utility model, when needs cleaning with when safeguarding, first link slot is separated with the second contiguous block, first contiguous block is separated with the second link slot, thus make the first main body and the second body portion from, can clear up respectively the first main body and the second main body and safeguard, this structure makes the cleaning of warm-air pipe and safeguards more convenient.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
Embodiment.Hot-blast stove can completely cut off a combined hot airduct for flame, forms as Figure 1-4, comprises the first main body 1, first main body 1 and be connected with the second main body 2; The outer wall that the outer wall that the inwall of the first described main body 1 is provided with the first fireguard 3, first main body 1 is provided with the first link slot 4, first main body 1 is also provided with the first contiguous block 5; The outer wall that the outer wall that the inwall of the second described main body 2 is provided with the second fireguard 6, second main body 2 is provided with the second link slot 7, second main body 2 is also provided with the second contiguous block 8; The first described link slot 4 is connected through bolt 16 with the second contiguous block 8, and the first contiguous block 5 is connected through bolt 16 with the second link slot 7; The first described fireguard 3 and the second fireguard 6 are dislocatedly distributed; The first described fireguard 3 and the second fireguard 6 are all in foliaceous.
During work, coal-fired in the combustion chamber 14 of body of heater 13, add hot-air, the hot-air after heating forms warm-air pipe that hot blast combines gained by the first main body 1 and the second main body 2 and enters Drying 15 pairs of materials and dry; In warm-air pipe, first fireguard 3 and the second fireguard 6 are dislocatedly distributed and form folding shape space, hot blast flows in folding shape space with flame, in flow process, flame is constantly blocked by the first fireguard 3 and the second fireguard 6, consumes, and final flame is blocked completely, is consumed, and reaches the object of isolated flame.First fireguard 3 and the second fireguard 6 are arranged to the curved surface of blade type, and hot blast is reduced in the flow resistance of warm-air pipe.When needs cleaning with when safeguarding warm-air pipe, first link slot 4 is separated with the second contiguous block 8, first contiguous block 5 is separated with the second link slot 7, thus the first main body 1 is separated with the second main body 2, can clear up respectively the first main body 1 and the second main body 2 and safeguard.
First air intake 9 diameter of aforesaid first main body 1 is greater than the first outlet air end 10 diameter; Second air intake 11 diameter of the second described main body 2 is greater than the second outlet air end 12 diameter.By this structure, make the diameter of the air inlet of warm-air pipe be greater than the diameter of air outlet, allow hot blast form draught head at air inlet and air outlet, cause hot blast flow velocity faster, drying efficiency is higher.
