Abstract
The utility model relates to drying matching equipment, in particular to a non-tube hot-blast stove which is widely used for drying various types of solid granular materials. The non-tube hot-blast stove is characterized in that partition plates are arranged between a cold blast channel and a hot blast channel, and a stove body is provided with cold blast inlets; and corresponding to the cold blast inlets, hot blast outlets are arranged on the stove body. Compared with the prior art, the utility model has the advantages that high-temperature and middle low-temperature hot blast can simultaneously output from a hot-blast stove, thereby avoiding a plurality of hot-blast stoves from being matched in order to output hot blast of different temperatures, the consumption of steel material is reduced, and hot blast output pipelines are reduced.
Description
Technical field
The utility model relates to dry corollary equipment, is specially a kind of pipe free hot-blast stove, is widely used in the drying of all kinds of solid granular materials.
Background technology
Chinese patent bulletin CN2338698 discloses design Wang Liming a kind ofly has a body of heater, be located at cold air duct and the hot-air channel in the body of heater and be folded in cold air duct and hot-air channel between the spiral smoke passage, described hot-air channel is a spirality channel, be provided with the radiated rib identical on the sidewall of burner hearth relying on the air channel rotation direction, this pipe free hot blast burner hearth heat exchange is abundant, favourable reduction fire box temperature increases the service life, and improves heat exchange efficiency.But when using this hot-blast stove dry solids class material, because of being dried the three phases of material in dry run, be warm-up phase constant-rate drying period, decreasing drying rate period, need the hot blast of different temperatures to carry out drying, and the hot-blast outlet of this pipe free hot-blast stove can only be exported the hot blast with a kind of temperature, can not satisfy this requirement of dry run needs different temperatures hot blast.
Summary of the invention
The purpose of this utility model is to provide a kind of hot-blast stove that two above different temperatures hot-blast outlets can be provided simultaneously.This hot-blast stove is exported the hot blast of different temperatures respectively in same body of heater, satisfied the requirement of drying process, simultaneously, adopts same body of heater heat exchange, has saved steel, the fireman of minimizing and hot blast conveying pipe road.
To achieve these goals, the technical solution adopted in the utility model is:
At same body of heater upper furnace body two cold wind imports are set, are provided with two hot-blast outlets with two corresponding bodies of heater of cold wind import.
The pipe free hot-blast stove is provided with dividing plate in cold air duct and the hot-air channel on same body of heater, dividing plate quantity is 1～5.
The body of heater of this many pipe frees hot-blast stove, be located at cold air duct and the hot blast in the body of heater and be folded in cold air duct and hot-air channel spiral smoke passage before, rely at described spirality hot-air channel and be provided with the radiated rib identical on the burner hearth sidewall with the air channel rotation direction.There is partition at cold air duct and hot-air channel middle part in body of heater (particular location is exported the temperature of hot blast as required and determined).Be respectively arranged with two cold wind imports and two hot-blast outlets on the body of heater.During work, the flue gas of burner hearth is introduced the spiral exhaust gases passes from the top, in the cold air of low temperature enter screw from the outermost layer cold air duct and spiral and move ahead, after the preliminary heating of exhaust gases passes, enter in the spirality hot-air channel of the inside layer, in two-sided heating situation, move ahead by spiraling, at last from outside body of heater, being arranged in the low temperature hot-blast outlet output at body of heater middle part to its spirality of lower edge from exhaust gases passes and burner hearth heat.
As a same reason, the cold air of high temperature enters from the outermost layer cold air duct, advance under the screw, after the preliminary heating of exhaust gases passes, pass exhaust gases passes from the bottom and enter hot-air channel, from flue gas by with the two-sided heating situation of burner hearth heat below spiral to its spirality channel of upper edge and to move ahead, at last from outside body of heater the high-temperature hot-air outlet output at body of heater middle part, high temperature, valve between the low temperature input channel, the temperature that can regulate high temperature, middle low temperature.
The utility model advantage compared with prior art is a high temperature, middle low temperature hot blast can be simultaneously from hot-blast stove output of mouth, avoided for the hot blast output of different temperatures can be arranged, need a plurality of hot-blast stoves to mate, reduced the consumption of steel, reduce the hot blast output channel simultaneously, its another advantage is to have reduced hot-blast stove quantity also just to have reduced operating personnel, reduces personal expenditures, can be widely used in the drying of materials such as all kinds of agricultural byproducts or food.

The specific embodiment
The utility model is described in further detail below in conjunction with the specific embodiment.In cold air duct and the hot-air channel dividing plate is set, body of heater is provided with the cold wind import, is provided with hot-blast outlet with the corresponding body of heater of cold wind import.
Described dividing plate quantity is 1.
Described cold wind import and hot-blast outlet quantity 2.
Body of heater 1, cold air duct 5, spiral smoke passage 11, hot-air channel 14 are all continued to use the prior art formation in Fig. 1.Constitute high temperature up and down, middle low-temperature zone with dividing plate 16.Cold wind input port 3 is respectively high temperature, middle low temperature air inlet, and dividing plate 15 is divided into upper and lower high temperature with the passage of heat, middle low-temperature space, hot-blast outlet 7 is respectively high temperature, middle low temperature outlet, adjusting valve 8 can be regulated high temperature, the temperature of middle low temperature and air quantity.
Claims (2)
1, pipe free hot-blast stove is characterized in that: at same body of heater upper furnace body two cold wind imports are set, are provided with two hot-blast outlets with two corresponding bodies of heater of cold wind import.
2, pipe free hot-blast stove according to claim 1 is characterized in that: described pipe free hot-blast stove is provided with dividing plate in cold air duct and the hot-air channel on same body of heater, dividing plate quantity is 1～5.
