Description

Lumber kiln

The utility model relates to a kind of lumber kiln.

At present, lumber kiln commonly used is divided into steam drying kiln and furnace-heated kiln two big classes substantially in the production.The steam drying kiln is to be thermophore with steam, by steam radiator, adds humid air in the heating kiln, and is that drying medium comes desiccated wood with hot humid air, and its shortcoming is to want supporting steam boiler with costliness, and the structure of kiln is also complicated, and investment is big; Furnace-heated kiln is to be the dry kiln of heat carrier with the furnace gas, and ubiquity: dry mass poor (mainly being inhomogeneous), and arid cycle is long, dangerously easily catches fire, and fuel consumes big various shortcomings such as (as the hot blast kilns); Subject matter is: 1, do not form reversible forced circulation air-flow.2, hot-blast stove is located at outside the kiln, and the hot blast that exchange produces blasts in the kiln with air blast, and its thermal efficiency is low, the burnup height.3, heat loss is big, is not easy to the deashing of boiler tube, also is unfavorable for building the disjunctor kiln of fork truck horizontally loaded type.

The purpose of this utility model is to provide a kind of lumber kiln.

The purpose of this utility model is achieved in that the kiln body adopts end wind type kiln body, promptly kiln is divided between the blower fan, heat exchange at anterior drying room and rear portion (being called for short between blower fan) at the rear portion of kiln or the perpendicular wind-guiding screen of an end (or wall), built-in or half built-in heat source furnace of a side lay between blower fan, the outlet flue of stove is connecting (having constituted the furnace gas radiator) such as rising smoke pipe, upper smoke box, decline smoke pipe, lower smoke box and chimneys; Another side between blower fan is equipped with the reversible axial flow blower of heatproof facing to the furnace gas radiator, and this blower fan is controlled by an automatic electric switch board, can carry out timing automatic commutation.When blower fan turned round, air-flow was blown over the furnace gas radiator, blowed to the material heap of drying room again, passed and was attracted to blower fan again after material is piled, and had finished the circulation of a transverse horizontal.Under this continuous air-flow circulation, heat exchange, the timber of heating, the effect of timber and cooling smoke pipe that dries up are also in generation constantly.

Owing to adopted such scheme, can use quite few investment, builds one or many Contiuum types, performance is suitable with the steam kiln, not only soon but also uniform; Quick heating, fuel saving; Little power consumption, cost are low; Working service is convenient, the better simply lumber kiln of structure.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the plane of first embodiment of the present utility model;

Fig. 2 is the I-I cutaway view of Fig. 1;

Fig. 3 is the II-II cutaway view of Fig. 1;

Fig. 4 is the plane of second embodiment of the present utility model.

The kiln body is a brick mix structure, the kiln body that belongs to the terminal fan type of vertical dress formula, side between the blower fan behind wind-guiding screen (wall) 9 in gate 7 is provided with built-in or half built-in thermal source cooking stove 1, the outlet flue of cooking stove 1 and rising smoke pipe join, the upper end of rising smoke pipe and upper smoke box 12 join, the upper end of decline smoke pipe also joins with upper smoke box 12, and the lower end of decline smoke pipe communicates with lower smoke box 13 again, and these smoke pipes group 2 and smoke box etc. have constituted the furnace gas radiator; After furnace gas (cigarette) comes out from the outlet flue of cooking stove, under the stack draught effect, along rising smoke pipe → upper smoke box → decline smoke pipe → lower smoke box → rising smoke pipe → upper smoke box → chimney → discharge atmosphere; Flue gas has heated smoke pipe and smoke box in this process.

Opposite side between blower fan facing to radiator, is equipped with the reversible axial flow blower 6 of heatproof, and this blower fan 6 can carry out the self-timing commutation by 4 controls of automatic electric switch board, thereby the air-flow that has formed the transverse horizontal Reversible Cycle passes material heap 8.When blower fan 6 runnings, air-flow is blown over the furnace gas radiator, heat exchange (also having cooled off smoke pipe etc. simultaneously) has taken place, produced hot humid air and as thermophore heat transferred by seasoned wood, simultaneously also being taken away by the seasoned wood vapor evaporated, thereby one has lifted to: heat exchange, the timber of heating, dry up the effect of timber and cooling smoke pipe.So constantly circulation has just reached the purpose of fast drying timber wood.

Upper smoke box 12 has the removable sky hole lid 10 that opens, and has day hole 11 corresponding to the kiln top roofing on the smoke box, day hole 11 by insulation day hole lid 10 lids close it.When smoke pipe needs deashing, can raise a day hole lid 10, tear open and open the upper smoke box lid, can carry out ash disposal up and down to smoke pipe.

Wall has transom window 3 behind the kiln body, in order to steam discharge and suction dry air.The keying in skylight is by handle, leverage, and manual adjustment is simple and practical.

Temperature in the kiln, humidity are measured by dried, wet-bulb thermometer, and the connection tank 5 that wet-bulb thermometer is used is housed in the kiln, have on its next door and observe wicket 14.Thermometer available pressure formula thermometer is the available heat resistance thermometer also.For improving the humidity in the kiln better, can in Ventilator Room, install water spray (mist) device 15 additional.

That shown in Figure 4 is second embodiment, it is the plane of fork truck horizontally loaded type kiln, its kiln body is arranged with vertical loading of kiln accent shown in Figure 1 and is turn 90 degrees, change has as shown in Figure 4 also all been done, (roof that transom window reaches between blower fan does not illustrate in the drawings) in positions such as gate, cooking stove, radiator, electrical control cubicles, thermometer tank, observation wicket.Its technique effect is with embodiment illustrated in fig. 1 identical.
