Abstract

The utility model provides a hot-air steam wood drying device, whose structure is characterized in that: the furnace hearth is designed in a ladder shape, the surrounding of the furnace hearth are all provided with blade type heat insulation liner, the furnace bridge uses a mesh plate, the blade type heat insulation liner have a plurality of strip-shaped, which is aslant fixed. An air channel is formed between the furnace wall and the blade type heat insulation liner in the structure, and the air channel is connected with the air discharging pipe, which supplied air to the combustion chamber to support the combustion, so the combustion is sufficient, the thermal efficiency is raised. Meanwhile, because of the blade type heat insulation liner, the temperature of the furnace hearth and the liner is lower, the high temperature corrosion of the furnace wall is effectively reduced. In addition, the blade type heat insulation liner is assembled, which is easy to maintain. The advantages of the utility model are that: rational design, simple structure, small energy, high thermal efficiency, rapid drying, the wood after drying is not deformation, cracks or discoloration, the steam production device is simple and practical, as the fuel is rice bran and wood shaving, the cost of wood drying is low, the utility model is most suitable to be used in small and medium-sized wood processing enterprises.

Description

A kind of hot blast steam timber drying device
Technical field:
The utility model relates to a kind of timber dewatering drying and burning equipment, especially a kind of hot blast steam timber drying device.
Background technology:
The discarded object wood chaff wood shavings of wood-working factory are a lot, with wooden chaff wood shavings is that fuel is obviously than being that fuel is more economical with new bavin, therefore, with the electricity is the method for drying wood of the energy, as micro-wave drying method, and infrared drying, also has the RCG15 type heat pump removal moisture drying of Beijing Coolers Factory manufacturing etc., concerning vast wood-working factory, because of its equipment complexity, costliness, energy consumption is big, cost is high seldom adopts.One of the timber initial stage heating steam that is dried makes in the timber inside and outside moisture content and humidity keep balance, and then dewaters that this is to guarantee not ftracture behind the drying of wood, and is indeformable, nondiscolouring, and can quick-drying key technology.As the QMI Steam Heating Wood Vacuum Drying Plant that Xi'an chemical makes, the Lin worker of Northeast Forestry University is the CLI type crosswind machine aluminium inner casing Steam Heating double track wood drying kiln that design is produced, because need boiler that the vapour source is provided, equipment cost is very high.The YRMH presteaming type hot air circulation timber stoving machine that at present the most suitable is Chengdu, Sichuan Taurus board, Shuande, Guangdong big good two beneficial board drying equipment Co., Ltd produces, its advantage is to be fuel with Xin Chai and timber processing waste, and burner hearth utilizes heat insulation liner plate, combustion-supporting airduct is formed, and water spray is produced steam above radiating tube, has reduced energy consumption and equipment cost, but chamber structure is too narrow, new bavin requires to cut off earlier 30~40cm batten just can enter the burner hearth burning, and electric energy increases, and labour intensity is big.The timber processing waste is wooden chaff wood shavings, many very difficult burnings in heat insulation liner plate in the burner hearth and grate.Lacked and flow at the bottom of the grate, fired not on firely, do not reached drying requirement, and be that the timber cost of fuel oven dry is also very high with new bavin.
Summary of the invention:
The purpose of this utility model provides a kind of burner hearth quick heating, sufficient combustion, and it is little to consume energy, and it is good to dry by the fire the lumber quality that, economical and practical hot blast steam timber drying device.
Architectural feature of the present utility model is: chamber design all is equipped with the heat insulation liner plate of vane type all around in echelon in the burner hearth, grate adopts sieve tray.The heat insulation liner plate of vane type is some strips, is to tilt fixing.
This structure forms ventilating duct between furnace wall and the heat insulation liner plate of vane type, and ventilating duct communicates with exhaust duct, to the combustion chamber blowing-in and combustion-supporting, makes sufficient combustion, improves the thermal efficiency.Because the heat insulation liner plate effect of vane type has reduced burner hearth and liner plate temperature, effectively alleviated the high temperature corrosion of furnace wall simultaneously.In addition, the heat insulation liner plate of vane type is for being assemblied to form, for ease of maintenaince.
The utility model has the advantages that: reasonable in design, simple in structure, it is very little to consume energy, thermal efficiency height, flash baking, timber after the oven dry is indeformable, do not ftracture, nondiscolouring, and it is simple and practical to produce steam unit, owing to be to do fuel with wooden chaff wood shavings, the kiln dried wood cost is low, and the most suitable middle-size and small-size wood processing enterprise uses.
Description of drawings:
Fig. 1 is the utility model furnace binding schematic diagram.
Fig. 2 is the body of heater side view.
Fig. 3 is heat insulation liner plate cutaway view.
Fig. 4 is heat insulation liner plate side view.
Fig. 5 is the inner vertical view of burner hearth.
Shown in the figure: 1, steam chest 2, burner hearth 3, fire door 4, ventilating duct 5, following grey cleaning door case 6, sieve tray 7, heat insulation liner plate 8, exhaust duct 9, valve for air exhaust switch 10, radiating tube 11, radiating tube deashing case 12, chimney 13, blower fan.
The specific embodiment:
The utility model is designed to a trapezoidal burner hearth, inboard wall of burner hearth adopts the heat insulation liner plate of vane type, it at the bottom of the heat insulation liner plate sieve tray, there have two blast pipes to carry out the secondary air draft at the bottom of the sieve tray to be combustion-supporting, this burner hearth quick heating, the burning extremely abundant, the thermal efficiency is high, the hot flue gas of producing is discharged chimney after by the radiating tube heat exchange, a steam chest is equipped with in the burner hearth top, temperature is up to 200~300 ℃, the globule drips to the burner hearth steam chest and is vaporized into water vapour immediately, and the blower fan above radiating tube will exchange heating air and water vapour through radiating tube and force to be pressed in the baking oven.
Steam chest 1 is located at burner hearth 2 tops, and burner hearth 2 is designed to trapezoidal, and the heat insulation liner plate 7 of vane type all is installed in the burner hearth 2 all around, and the heat insulation liner plate of vane type is that the some rectangular plates of refractory material are to tilt to fix shape such as shutter.Can change, the bottom grate adopts sieve tray 6, and heat insulation liner plate and sieve tray form the stove internal portioning layer, form ventilating duct 4 between itself and the furnace wall, the heat insulation liner plate leaf of vane type leaf is ventilated, and ventilating duct 4 is communicated with under the furnace bottoms grey cleaning door case 5 and communicates with exhaust duct 8, and valve switch 9 is housed on the exhaust duct 8.
When burner hearth was worked, combustion air entered furnace wall ventilating duct 4 from exhaust duct 8, made secondary blast by furnace wall ventilating duct 4 to heat insulation liner plate 7 in burner hearth again, realized cooling combustion-supporting and furnace wall and liner plate.Snakelike radiating tube 10 turnings of the logical chimney 12 in top are interval with radiating tube deashing case 11, and the hot flue gas of production is discharged chimney 12 from radiating tube 10 behind heat radiation case 11, and the blower fan 13 of radiating tube top is pressed into baking oven with hot blast steam.
