Description

The timber stoving machine

The utility model relates to a kind of timber stoving machine.

At present, adopt the timber stoving machine of scoot as thermal source, in order to guarantee the timber stoving quality,, often add a steam oven in addition except burner hearth, make the difficult proportioning of regulating temperature and humidity of drying equipment like this, and dry out nondiscolouring, do not split, indeformable timber, key is to grasp the proportioning and the oven dry hydrofuge of temperature and humidity, this timber stoving machine operation commonly used is numerous and diverse, dry mass is wayward, and heat energy utilizes insufficient; Mostly be indoor installation again, can not remove in the strange land, this work brings very big inconvenience to the drying of wood.

The utility model is intended to propose a kind of drying operation handy and safe, can ensures the quality of products again, but and the wood dryer of energy savings.

The timber stoving machine that the utility model proposes, mainly by preceding casing, rear box, air inlet pipe, dehumidification tube and row's steam pipe are formed, before it is characterized in that, rear box is hermetic type, the rear box bottom has passage to link to each other with preceding lower box, burner hearth is arranged in the rear box, heat exchanger and circulation steam generator, the burner hearth of inverted cone bench-type is in the middle and lower part of rear box, on burner hearth, settle the circulation steam generator, the burner hearth both sides are heat exchangers, one row's axial-flow type scavenger fan is set respectively on heat exchanger top, the internal upper part of rear box has one deck inner insulating layer, and preceding casing is provided with the placing of material frame, also is provided with fan blade and blade shaft fixed support.

The structure of circulation steam generator is that a water tank is set on burner hearth, places some U type water service pipes in burner hearth.

Because the timber stoving machine that the utility model proposes has said structure, the burner hearth of inverted cone stage body, it is faster to burn, more thorough, can make full use of thermal source, reach energy-conservation effect, settle the circulation steam generator on burner hearth, some U type water service pipes of placing in the burner hearth can produce steam and capable of circulation to water tank, make vaporific efficient higher, complete machine is only used a burner hearth, just can produce hot blast and steam simultaneously, and the operation control of dryer is oversimplified, no matter the size of combusting firepower, steam and hot blast temperature all are directly proportional, and meet the essential condition of the drying of wood, and the axial flow ventilating fan was used for hot gas and steam the past, the passage that the rear box bottom links to each other, deliver to the timber heap and promote circulative convection, the past come-up of the air that temperature is high, what temperature was low sinks, and promotes rate of drying, set air inlet pipe and dehumidification tube, by convective sources reason and atmospheric density principle, reach the dried purpose of entering the row of wetting, make timber can reach uniform moisture content.Such timber stoving machine operation handy and safe, can ensure the quality of products again, but and energy savings.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the structural representation of case before the utility model embodiment;

Fig. 3 is the structural representation of the utility model embodiment rear cabinet.

With reference to Fig. 1, Fig. 2 and Fig. 3, the timber stoving machine that the utility model proposes, mainly by preceding casing 1, rear box 2, air inlet pipe 3, dehumidification tube 4 and row's steam pipe 5 are formed, before it is characterized in that, rear box is hermetic type, rear box 2 bottoms have passage to link to each other with preceding casing 1 bottom, burner hearth 6 is arranged in the rear box 2, heat exchanger 7 and circulation steam generator 8, the burner hearth 6 of inverted cone bench-type is in the middle and lower part of rear box 2, on burner hearth 6, settle circulation steam generator 8, burner hearth 6 both sides are heat exchangers 7, one row's axial-flow type scavenger fan 9 is set respectively on heat exchanger 7 tops, the internal upper part of rear box has one deck inner insulating layer 10, be provided with placing of material frame 13 in the preceding casing 1, also be provided with fan blade 11 and blade shaft fixed support 12; The structure of circulation steam generator 8 is that a water tank 15 is set on burner hearth 6, in burner hearth, place some U type water service pipes 14, because the timber stoving machine that the utility model proposes has said structure, the burner hearth of inverted cone stage body, it is faster to burn, more thorough, can make full use of thermal source, reach energy-conservation effect, on burner hearth, settle the circulation steam generator, some U type water service pipes of placing in the burner hearth, can produce steam and capable of circulation to water tank, make vaporific efficient higher, complete machine is only used a burner hearth, just can produce hot blast and steam simultaneously, the operation control of dryer is oversimplified, no matter the size of combusting firepower, steam and hot blast temperature all are directly proportional, and meet the essential condition of the drying of wood, and the axial flow ventilating fan was used for hot gas and steam the past, the passage that the rear box bottom links to each other, deliver to the timber heap and promote circulative convection, the past come-up of the air that temperature is high, what temperature was low sinks, and promotes rate of drying, set air inlet pipe and dehumidification tube, by convective principles and atmospheric density principle, reach the dried purpose of entering the row of wetting, make timber can reach uniform moisture content.Such timber stoving machine operation handy and safe, can ensure the quality of products again, but and energy savings.
