Abstract
The utility model relates to a wood drying furnace which is composed of a furnace chamber and a steam vaporizing device. The utility model is characterized in that the furnace chamber is a trapeziform furnace chamber. The bottom of the furnace chamber is provided with a primary air inlet furnace grating, and one side of a furnace door is provided with a secondary air inlet furnace grating. The inner side of the furnace chamber is provided with a sandwich-layer water tank which can be an annular water jacket with three surfaces. The sandwich-layer water tank is connected with the steam vaporizing device. The upper part of the steam vaporizing device is provided with a preheating water tank, a water inlet valve and a safety valve; the lower part of the steam vaporizing device is provided with a water outlet valve and a steam nozzle. Water enters the preheating water tank and enters the sandwich-layer water tank to be boiled, and vaporized water is ejected from the steam nozzle. The furnace chamber is provided with two furnace gratings to take in air from two directions, so the oxygen increasing effect is obvious, and the material which is not easy to be combusted such as wood chips, wood dust and coal can be combusted quickly and thoroughly. A furnace wall is provided with the sandwich-layer water tank, so the oxidation of the furnace wall is reduced, and the service life of the wood drying furnace is prolonged. Meanwhile, the utility model uses water steam as a medium for drying wood, so the wood has no crack, no deformation and no discoloration. The utility model is an ideal heat source for drying wood.
Description
The utility model relates to a kind of drying device, refers more particularly to the drying oven in a kind of timber drying device.
The present more domestic device that is used for timber stoving, from the angle of saving the energy, reducing cost, mostly adopt burning to produce heat energy, resemble Chinese patent ZL93224125.5 a kind of utility model is provided, it is characterized in that burner hearth is designed to down four rhombuses as drying source; Water sprays from the water spout that is installed in burner hearth, smoke box or radiating tube top, meets burner hearth, smoke box or the radiating tube vaporization of high temperature, is pressed in the baking oven by ventilating fan.Yet owing to burner hearth is single air intake grate, grate more easily takes place in combustion process is caused in the burner hearth the not enough incomplete combustion that causes of oxygen supply by resistance, in this external combustion process, because high temperature directly contacts with hearth wall, the oxidized and phenomenon of burning in furnace wall at high temperature easily takes place; Cold water is directly ejection from water spout, has reduced the room temperature of heat-exchange device, and some heat steam is run away, and has reduced the heat energy utilization rate.
The purpose of this utility model is to provide a kind of can improve burner hearth internal combustion situation, can protect the furnace wall effectively, and the device that heat exchanger effectiveness is improved.
For this reason, the utility model provides a kind of timber drying oven, comprise burner hearth and steam vapourizing unit, described chamber design is burner hearth in echelon, its bottom is except that being equipped with air intake grate, in fire door one side the secondary air grate is housed also, the burner hearth inboard is designed to the interlayer water tank, and the interlayer water tank is connected with the steam vapourizing unit.
An air intake grate correspondence in the described trapezoidal burner hearth is shutter once, and secondary air grate correspondence has the secondary air door.
Described interlayer water tank is three ring-shaped water jackets, and water jacket top is connected with the steam vapourizing unit.
Described steam vapourizing unit top is provided with preheating water tank, water intaking valve, safety valve, and the below is provided with outlet valve, steam nozzle.Water enters the boiling of interlayer water tank at last behind the preheating water tank, vaporization is after the ejection of steam nozzle.Above device, ventilating fan is housed, will will force to send in the baking oven through the hot-air and the steam of radiating tube exchange.
Because burner hearth adopts the two air intakes of two grates, oxygenation effect is obvious, makes rapid burning of nonflammable materials such as wood chip, wooden chaff, coal and burning thoroughly; The furnace wall is provided with the interlayer water tank, and oxidation is reduced in the protection furnace wall, thereby increases the service life; Owing to, make the unlikely cracking of timber, distortion, variable color, be the desirable thermal source of kiln dried wood simultaneously with the medium of steam as kiln dried wood.
Below with reference to accompanying drawing the utility model is described in detail.
Fig. 1 is the utility model front schematic view.
Fig. 2 is that the A of Fig. 1 is to generalized section.
As shown in Figure 1 and Figure 2, fuel such as wood chip, wooden chaff, coal enter trapezoidal burner hearth 1 and burn from fire door 5, and hot flue gas, is discharged from smokejack 14 after quilt is managed the external cooling air heat exchange by stainless steel radiating tube 13.When kiln dried wood, open water intaking valve 9, the water among the preheating water tank 8 enters in the interlayer water tank 4 by water pipe, under the burning of high-temperature burner hearth, the water in the interlayer water tank 4 is vaporized into steam very soon, through 12 ejections of steam nozzle, sent in the baking oven by ventilating fan Final 16 system, make timber preheating in the baking oven.For preventing that the water in the interlayer water tank 4 from causing water directly to spray from steam nozzle 12 because of water level is too high, the spy is provided with outlet valve 11, with the adjusting water level, and shows from water gauge 15; For to prevent that the steam in the interlayer water tank 4 is too saturated, the spy is provided with safety valve 10 with regulation and control in addition.Ventilating fan 16 forces to press to the drying oven bottom with natural air, carries out being admitted to baking oven by the drying oven bottom after the heat exchange with several stainless steel radiating tubes 13, interlayer water tank 4 and trapezoidal burner hearth 1 in the way, realizes the timber dewatering drying.
