Abstract
The utility model relates to a steam exhaust type veneer leveling dryer, which is the special equipment for drying veneers in the manufacturing process of plywoods, and includes a machine frame, driving devices, a movable heating plate, medium heating plates, a fixed heating plate and a heat medium conveying system, wherein the driving devices are installed at the bottom of the machine frame; the movable heating plate is installed on the driving devices; and steam exhaust passages are arranged on the movable heating plate, the medium heating plates and the fixed heating plate. In the utility model, as the steam exhaust passages are arranged on all the heating plates, the veneer is pressed and dried, so that water content in the veneer is removed and the veneer is leveled, as a result, the warpage and cracking of the veneer are avoided, and the energy consumption is little; all the heating plates adopt double-circuit heat medium circulation, the temperature difference at different parts on the heating plates is low, the dried veneer has uniform water content; and all the heating plates are formed through welding thick-walled square pipe profiles, so that the processing is easy, the structure of the complete machine is simple, and the manufacturing cost is low.
Description
Technical field
The utility model belongs to leveling drying machine technical field, particularly relates to a kind of steam discharge formula veneer leveling drying machine, specifically, is veneer drying special equipment in the plywood production process.
Background technology
Both at home and abroad, veneer drying is used guipure (roller) drying machine of cross-ventilation heat exchange mode usually at present.Board using poplar board, China fir veneer to speed is given birth to can not reach desirable effect with above-mentioned drying machine.The veneer poor flatness that chain-belt conveyer veneer drier is dry, buckling deformation, energy consumption is high, and investment cost is high, and floor space is big.The veneer that roller dryer is dry, easy to crack, drying time is long, device structure is complicated, the cost height.Some producer adopts common multi-daylight press dried single board, for making veneer moisture rapid evaporation, need repeatedly open steam discharge during dried single board; Carry out the type of respiration drying, not only energy consumption is high, and productivity ratio is low; And heating platen has only a thermal medium closed circuit; Because of Path too long, cause on the same heating platen temperature difference big, cause the dried single board moisture content inhomogeneous.
The utility model content
To the technical problem of above-mentioned existence, for solving existing veneer drying poor flatness, moisture content is uneven, energy consumption is high, investment is big technological deficiency, the utility model provides a kind of steam discharge formula veneer leveling drying machine.
The utility model solves the technical scheme that its technical problem adopted:
The utility model comprises frame, drive unit, movable heating plate, middle heating plate, fixed heated plate and thermal medium induction system; Said frame bottom is equipped with drive unit; Movable heating plate is installed on the drive unit, is equipped with exhaust passage on said movable heating plate, middle heating plate and the fixed heated plate.
Said each heating plate is welded by a plurality of heavy wall square tube section bars, forms exhaust passage between adjacent square tube, and each square tube is built-in with the thermal medium pipeline.The built-in thermal medium pipeline of said each heating plate is respectively thermal medium input pipe and thermal medium efferent duct, and the thermal medium of importing every heating plate forms the thermal medium closed circuit of two parallel connections in heating plate.Described drive unit is at least two hydraulic cylinders or jack.
The utlity model has following advantage:
1. the utility model is a steam discharge contact heat drying veneer, and heating plate is provided with exhaust passage, and down dry and discharge water divides heat to flatten veneer in compacting to make veneer, veneer not warpage, do not ftracture, less energy consumption.
2. heating plate is the circulation of double loop thermal medium in the utility model, and different parts has a narrow range of temperature on the heating plate, and dry back veneer moisture content is even.
3. heating plate is welded with heavy wall square tube section bar in the utility model, handling ease, and complete machine structure is simple, low cost of manufacture.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model heating board structure sketch map;
Fig. 3 is the utility model heating plate thermal medium circulation sketch map.
Among the figure: 1. frame, 2. hydraulic cylinder, 3. movable heating plate, 4. locating piece, 5. backstay, 6. in the middle of heating plate, 7. fixed heated plate, 8. square tube, 9. exhaust passage, 10. input pipe, 11. efferent ducts, 12,12 '. the thermal medium closed circuit.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further detailed description.
Embodiment: like Fig. 1, shown in Figure 2; The utility model comprises frame 1, drive unit (this example adopts hydraulic cylinder 2), movable heating plate 3, fixed heated plate 7, middle heating plate 6 and thermal medium induction system; Said frame 1 bottom is equipped with at least two hydraulic cylinders 2 (this example is two); Movable heating plate 3 is installed on the hydraulic cylinder 2; Heating plate 12 is provided with four locating pieces 4 in the middle of corresponding every on frame 1, and heating plate 6 is provided with four backstays 5 in the middle of each, and middle heating plate 6 places on the locating piece 4 through backstay 5; Fixed heated plate 7 is fixed on frame 1 top board, is equipped with exhaust passage 9 on said movable heating plate 3, middle heating plate 6 and the fixed heated plate 7.Drive unit wherein also can adopt jack.
As shown in Figure 3, said each heating plate is welded by heavy wall square tube section bar 8, has certain strength and stiffness, forms exhaust passage 9 between each square tube.Said every heating plate is provided with thermal medium input pipe 10 and thermal medium efferent duct 11, and thermal medium gets into each heating plate through the thermal medium induction system, the thermal medium of importing every heating plate in heating plate, form the thermal medium closed circuit 12,12 of two parallel connections '.
The utility model adopts steam discharge contact pressurized, heated dried single board, and hot plate directly contacts veneer and conducts heat, and the thermal efficiency is high also can effectively discharge the water vapour in the veneer through exhaust passage, makes its veneer heat leveling rate of drying fast, boosts productivity the minimizing energy consumption.Dried veneer is smooth, good planeness, moisture content are even.
