Abstract

The utility model provides a steam hot wind wood drying device. The steam hot wind wood drying device comprises a drying box and a steam air heater provided with an air blower, a diversion partition board is transversely arranged at the upper portion in the drying box, a cavity above the diversion partition board serves as a heating chamber, a cavity below the diversion partition board serves as a drying chamber, ventilating air channels are reserved between the left side and the right side of the diversion partition board and the lateral walls of the drying box, the heating chamber is communicated with the drying chamber through the ventilating air channels, an axial flow fan capable of laterally blowing air is arranged in the heating chamber, an air supplying pipe of the steam air heater is connected with the heating chamber, an air return pipe of the steam air heater is connected with the drying chamber, and moisture removal devices are arranged on the left side and the right side of the top of the drying box. The steam hot wind wood drying device has the advantages that the method that hot air is input from the bottom is changed into the method that the hot air is input from the top, so that air flow can be reversibly circulated in the vertical direction, longitudinal direction and horizontal direction, wood is more uniformly dried, and drying efficiency and quality are improved.

Description

Steam hot wind timber drier

Technical field

The utility model relates to a kind of steam hot wind timber drier.

Background technology

Traditional drying of wood mode is that to adopt under the sun airing to carry out natural drying, but this mode rate of drying is slow, and can take larger space, and drying efficiency is low.Although have now some timber driers, mostly adopt bottom to enter the mode of hot blast.Bottom is entered hot blast and is tended to cause bottom timber to be heated for a long time, the long charing that also even can cause timber of heated time, and the timber of other parts can not fully be heated, thus make the timber in drying baker can not get thermally equivalent and dry.Affect drying efficiency and the quality of timber.

Summary of the invention

For solving above technical deficiency, the utility model provides a kind of reasonable in design, the steam hot wind timber drier that drying efficiency and quality are higher.

The utility model is realized by following measures:

A kind of steam hot wind timber drier of the present utility model, comprises drying baker and with air blast

Steam heat wind furnace, described drying baker internal upper part is horizontally arranged with diaphragm, diaphragm top cavity is heating clamber, the cavity of diaphragm below is drying chamber, between the limit, the left and right sides of described diaphragm and the sidewall of drying baker, leave ventilation air duct, described heating clamber is connected by ventilation air duct with drying chamber, in heating clamber, be provided with can left and right blowing axial flow blower, the ajutage of described steam heat wind furnace connects heating clamber, the backwind tube of steam heat wind furnace connects drying chamber middle part, and the left and right sides, described drying baker top is provided with humidity-discharging device.

In above-mentioned heating clamber, middle part is vertically provided with heating clamber is divided into the two-part supporting clapboard in left and right, and described axial flow blower is arranged on supporting clapboard.

The casing of above-mentioned drying baker is followed successively by color steel, glass wool thermal insulation board and aluminium sheet from outside to inside.

The beneficial effects of the utility model are: hot blast mode is entered in traditional bottom and be improved to top and enter hot blast, make upper and lower, longitudinal, the horizontal Reversible Cycle of air-flow, humiture distributes more even, and timber stoving is more even, has improved drying efficiency and quality.

Accompanying drawing explanation

Fig. 1 is perspective view of the present utility model.

Fig. 2 is cross-sectional view of the present utility model.

Wherein: 1 drying baker, 2 steam heat wind furnaces, 3 ajutages, 4 backwind tubes, 5 diaphragms, 6 axial flow blowers, 7 supporting clapboards, 8 heating clambers, 9 ventilation air ducts, 10 drying chambers.

The specific embodiment

As shown in Figure 1, 2, a kind of steam hot wind timber drier of the present utility model, comprises drying baker and with the steam heat wind furnace 2 of air blast, in drying baker 1, puts timber.Steam heat wind furnace 2 is as existing firing equipment, comprise the parts such as combustion chamber, thermal energy conversion chamber, steam raising plant, auxiliary combustion equipment, blower fan, chimney, fuel can adopt sawdust, wood shavings, leftover pieces and coal etc., carries high-temperature hot-air or steam, thereby make the drying of wood to drying baker 1.

Drying baker 1 internal upper part is horizontally arranged with diaphragm 5, diaphragm 5 top cavitys are heating clamber 8, the cavity of diaphragm 5 belows is drying chamber 10, between the limit, the left and right sides of diaphragm 5 and the sidewall of drying baker 1, leave ventilation air duct 9, heating clamber 8 is connected by ventilation air duct 9 with drying chamber 10, in heating clamber 8, be provided with can left and right blowing axial flow blower 6, the ajutage 3 of steam heat wind furnace 2 connects heating clamber 8, the backwind tube 4 of steam heat wind furnace 2 connects drying chamber 10, and drying baker 1 left and right sides, top is provided with humidity-discharging device.Humidity-discharging device comprises moisture exhausting port, connecting stay wire, gear arm-tie.For axial flow blower 6 is fixed, the interior middle part of heating clamber 8 is vertically provided with heating clamber 8 is divided into the two-part supporting clapboard 7 in left and right, and axial flow blower 6 is arranged on supporting clapboard 7.The casing of drying baker 1 is followed successively by color steel, glass wool thermal insulation board and aluminium sheet, high insulating effect from outside to inside.

When running well, fuel is fully burning in the combustion chamber of steam heat wind furnace 2, produce heat energy, under the effect of air blast, high temperature gas flow enters between blower fan 8 by air blast by ajutage 3, and axial flow blower 6 forward or reverse blow hot blast and flow to the left or to the right, from ventilation air duct 9, are blown into drying chamber 10, horizontal between the timber that hot-air flow is put in drying chamber 10, horizontal Reversible Cycle, thus make timber stoving more even.Then air-flow is assembled and returns to steam heat wind furnace 2 by backwind tube 4 to drying chamber 10 middle parts, continues heating repeatedly, thereby has reclaimed a large amount of heats, and air blast integrates return air and air blowing function, has reduced significantly oven dry cost, has shortened the oven dry cycle.The steam raising plant of steam heat wind furnace 2, can produce a large amount of atmospheric steams simultaneously, can steam be sent in hothouse according to the requirement of drying process in good time, and timber is sprayed to steaming.

The above is only the preferred embodiment of this patent; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the art of this patent principle; can also make some improvement and replacement, these improvement and replacement also should be considered as the protection domain of this patent.
