Description

Direct-fired dehydrator

Technical field

This utility model relates to dehydrator field, is specifically related to a kind of natural gas or the direct-fired drying of liquefied gas drying Machine.

Background technology

Existing Thallus Laminariae is dried and is used Boiler Steam drying and air stove drying, the steaming that i.e. steam boiler produces Vapour, becomes steam into condensed water by radiator, blows radiator with blower fan, and cold wind is become hot blast to carry out drying.

This drying mode has been used up how many years, and this drying mode there is the problem that 1, steam is by dissipating Hot device becomes the temperature of condensed water and is up to 80 spend more, and this part high temperature water reuse is limited；2, steam boiler is used to pollute ring Border；3, for drying, steam boiler is dried is heating indirectly, and the thermal efficiency reaches 70%-80%, adds the cost of product；4, make With steam boiler costly, such as maintenance expense, the electricity charge, water rate, fireman's expense etc..

Utility model content

Burned flame is changed into hot blast by the purpose of this utility model exactly, it is provided that the thermal source of drying, prevents burning Flame enters in material and is burnt out by material.

This utility model be the technical scheme is that to include drying materials room, blower fan 1, burning for achieving the above object Mixing chamber and burner 4, burning mixing chamber includes shutter 2, waste heat air inlet 3, inner bag 5, burning hot blast changeover bobbin 6 and insulation Layer 7, burning mixing chamber two ends connecting fan 1 and burner 4 respectively, inner bag 5 is arranged on inside burning mixing chamber, and heat-insulation layer 7 sets Putting outside burning mixing chamber, play heat insulation effect, shutter 2 is arranged on the burning mixing chamber side of burner 4 lateral location On wall, constantly increasing new empty wind toward burning mixing chamber, shutter 2 size is adjustable, it is ensured that dry intake, waste heat air inlet 3 tops being arranged on burning mixing chamber, return to burning mixing from drying materials room hot blast out again through waste heat air inlet 3 Room, burning hot blast changeover bobbin 6 is arranged on the inside of burning mixing chamber and is connected with burner 4, and burning hot blast changeover bobbin 6 is used for collecting Middle heat, makes burner 4 directly heat the air in burning hot blast changeover bobbin 6 and be directly sent directly into by hot blast by blower fan 1 Drying materials room, improves the thermal efficiency of burning blender.

The distance of described burner 4 and blower fan 1 is more than 900mm, enters drying materials room with fire resistant by blower fan 1 and lights Material.

The caloric value of described burner 4 is 400,000 kilocalories, and described burner 4 also includes temperature controller, and control mode is Two-stage nitration fire.

Described shutter 2 is two, and is separately positioned on the sidewall of burning mixing chamber of 4 liang of side positions of burner.

Heat-insulation layer 7 material is the aluminum silicate insulation material of heatproof.

Direct-fired dehydrator of the present utility model instead of original steam kettle Kiln seasoned tradition drying mode, decreases Pollute environment, and because using direct-fired drying mode, improve product than the original indirect drying mode using steam boiler Energy 30%, saves the cost of drying, as without boiler electricity, water, maintenance expense etc., it is not necessary to build boiler room simultaneously, it is not necessary to artificial Control, all realize automatization and dry.

Detailed description of the invention

As Figure 1-3, direct-fired dehydrator of the present utility model, including drying materials room, blower fan 1, burning mixing chamber With burner 4, burning mixing chamber includes shutter 2, waste heat air inlet 3, inner bag 5, burning hot blast changeover bobbin 6 and heat-insulation layer 7, combustion Burning mixing chamber two ends connecting fan 1 and burner 4 respectively, inner bag 5 is arranged on inside burning mixing chamber, and heat-insulation layer 7 is arranged on combustion Outside burning mixing chamber, playing heat insulation effect, shutter 2 is arranged on the burning mixing chamber sidewall of burner 4 lateral location, no Disconnected increases new empty wind toward burning mixing chamber, and shutter 2 size is adjustable, it is ensured that drying intake, waste heat air inlet 3 is arranged on The top of burning mixing chamber, returns to the mixing chamber that burns, burning from drying materials room hot blast out again through waste heat air inlet 3 Hot blast changeover bobbin 6 is arranged on the inside of burning mixing chamber and is connected with burner 4, and burning hot blast changeover bobbin 6 is used for concentrating heat, Burner 4 is made to directly heat the air in burning hot blast changeover bobbin 6 and directly by blower fan 1, hot blast is sent directly into drying materials Room, improves the thermal efficiency of burning blender.

Work process:

First, burner 4 is lighted a fire, and burner 4 burned flame becomes at burning mixing chamber through burning hot blast changeover bobbin 6 Hot blast, burning mixing chamber has two shutters 2, constantly increases new empty wind toward burning mixing chamber, is become by burning mixing chamber Become hot blast, finally by blower fan 1, the high-temperature hot-air of burning mixing chamber is delivered to drying materials room, material drying.

Burner 4 also sets up temperature controller, and temperature controller automatically controls burner 4 by the hot blast temperature detected Big fire and little fire, temperature controller sets upper and lower bound as required, automatically stops when the temperature detected reaches the upper limit Big fire, changes little fire into and burns away, and homogeneous temperature declines, and when temperature reaches lower limit, burner 4 lights big fire, temperature automatically Rising, until reaching the upper limit, so circulating work, it is ensured that drying materials.

During work, the outer surface of the heat-insulation layer 7 outside burning mixing chamber has not a particle of heat.

Advantage of the present utility model is as follows:

1, instead of original steam kettle Kiln seasoned tradition drying mode, decrease pollution environment；

2, because using direct-fired drying mode, production capacity is improved than the original indirect drying mode using steam boiler 30%；

3, the cost dried is saved, as without boiler electricity, water, maintenance expense etc., it is not necessary to build boiler room, it is not necessary to artificial Control, all realize automatization and dry.
