The specific embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and operation principle, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present invention, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present invention structure expressed as Fig. 1 to Fig. 7, the present invention is a kind of board drying apparatus, comprises oven dry casing 1, frame 2 and heater 3, and plank 8 is dried.Oven dry casing 1 is long box component, and general length is tens meters extremely tens of rice, and the width of casing is several meters, and for example the scope of width is between 2 meters～4 meters.Tank surface preferably is provided with heat-resisting heat-insulation layer, reduces scattering and disappearing of the interior heat of casing.The two ends of casing are the opening of the narrow strip of level, and the opening of an end is the charging aperture of plank, and plank 8 is scattered in a row and enters; The other end then is a discharging opening.The charging and discharging mouth adopts flexible shielding plate, can easily it be pushed open when input and output material, will import and export sealing during nature, and its structure generally adopts the rubber curtain of suspension.The charging and discharging mouth is that horizontal direction is wide, and its width can make polylith plank 8 enter oven dry casing 1 side by side.Outside charging aperture, a platform contour with charging aperture should be set, to make things convenient for pushing of plank 8.Equally, outside discharging opening, the material-receiving device of an oven dry sheet material should be set also.
In addition, the side of oven dry casing 1 is provided with a plurality of peep holes, and peep hole is provided with the door that can open, when needing observation, opens and observes door, the working condition of oven dry and pressing in the inspection box.Oven dry casing 1 outer diverse location is provided with thermometer, and its temperature-sensitive head (being temperature sensor) is located in the casing.Effect is everywhere a real time temperature in the test box, so that regulate.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realization makes the oven dry of plank more even, better effects if; Improve the goal of the invention of the performance of plank in oven dry, the technical scheme that the present invention takes is:
As depicted in figs. 1 and 2, this board drying apparatus provided by the present invention, the oven dry casing 1 of drying plant wherein are provided with many to pressure roller 4 parallel to each other, arranged in pairs, form a row; The every pair of pressure roller is for arranging up and down, and described plank 8 is sandwiched in up and down between two pressure rollers 4, and motion under it drives.
Technique scheme has some advantages like this:
Owing to taked in oven dry, plank 8 to be carried out roll-in, dry at the volley, drying effect is better, each position oven dry on each plate and the plate evenly, the aridity of plank (otherwise or be called moisture content) is more even;
Plank is through the roll extrusion of pressure roller, and the structure of fibrous tissue of material is fine and close more, and intensity improves;
The surface of plank is reduced surface roughness by the pressure roller roll extrusion, has improved surface quality and surface strength, strengthens the wearability of plank;
Reduce the workload of scraping and process in follow-up surface, enhance productivity.
The multilayer plan of establishment of pressure roller:
Many also can formation up and down pressure roller 4 parallel to each other, arranged in pairs arranged more, increases the oven dry number of plies, thereby improves the quantity of drying plank simultaneously, enhances productivity, and heat energy is made full use of.
When multilayer is provided with pressure roller 4, can implement by the structure shown in Fig. 6 or Fig. 7.
The present invention has also proposed structure exemplifying embodiment more specifically to technique scheme, to realize and to improve above-described overall technological scheme better:
Many pressure roller is implemented by following two examples in the horizontal direction:
1, as shown in Figure 1, of the present invention many pressure roller 4 horizontal intervals are distributed in one plane.
If the internal stress of plank 8 is less, then can adopt the method for present embodiment to carry out.
2, as shown in Figure 4, of the present invention many to the distribution of pressure roller 4 horizontal intervals, a highly staggered dislocation is arranged between the adjacent pressure roller 4.
If the internal stress of plank 8 is bigger, then can adopt the method for present embodiment to carry out, plank 8 is through the changing of the relative positions up and down of pressure roller 4, and internal stress reduces greatly, improves the performance of plank 8, and its deflection after oven dry is reduced.Particularly the dislocation rolling under higher temperature makes the more thorough of its stress elimination, has avoided the residual stress that smoothing produces under the cold conditions.
The topology example of heater 3:
As shown in Figure 3, heater 3 of the present invention is a heating tube 5, and between pressure roller 4, be a plurality of " U " shape around.
The topology example of heating tube:
The example of pressure roller motion structure:
Described pressure roller 4 passes through an independent chain-drive mechanism transmission between every adjacent two couple.
The topology example of elasticity press mechanism 9:
The a pair of pressure roller of arranging up and down 4 of the present invention wherein on Shang Mian the pressure roller 4, is provided with elasticity press mechanism 9, makes when passing through plank 8 between two pressure rollers isostasy that bear on the surface of plank.
Consider the in uneven thickness of plank 8, just do not adopt the changeless structure of up-down rollers spacing, and the structure that should adopt two roller gaps to float.In order to keep the certain pressure to plank 8, so establish elasticity press mechanism 9 on the superincumbent pressure roller 4, its structure as shown in Figure 5.
Elastic pressure adjusting device in the elasticity press mechanism is provided with example:
Be provided with the elastic pressure adjusting device in the elasticity press mechanism 9 of the present invention, regulate the elastic pressure of elasticity press mechanism 9.Because different thicknesss of slab, the perhaps long-time back elasticity of using changes, and need carry out adaptive adjustment to the elastic force in the elasticity press mechanism 9.
The exemplifying embodiment that heater 3 is provided with:
The present invention also provides the sheet material furnace drying method that adopts with described board drying apparatus, and its technical scheme is:
In oven dry, adopt 4 pairs of planks of pressure roller 8 to carry out roll extrusion and drive, plank 8 is dried at the volley;
Meanwhile, exert pressure in the surface of 4 pairs of planks 8 of pressure roller, makes the fibr tissue of timber 8 fine and close more;
Tumbling is carried out on the surface of 4 pairs of planks 8 of pressure roller, makes the surface finishing of timber 8, reduces roughness;
4 pairs of planks 8 of pressure roller are under the thermal pressure effect, and its residual stress is eliminated in the smoothing that misplaces.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
