Abstract
The utility model relates to a timber drying device-a super far infrared timber dryer, comprising an operating chamber and a drying chamber. The drying chamber is provided with an inner door and an outer door the two double layer doors; an insulating layer is provided between an outer shell and an inner shell; the top surface of the drying chamber is provided with a vent hole, and a regulating board is provided above the vent hole; the inner wall surfaces of both sides of the drying chamber are in turn increased with installation plate type super far infrared heating elements; the bottom surface of the drying chamber is provided with a pipe type super far infrared heating element and a track; a timber-loading car can slide on the track. The super far infrared timber dryer has short drying period with favorable quality, the texture of the timber does not change after drying with easy manufacturing, and the qualification rate is over 98 percent. The super far infrared timber dryer has low cost, and the drying cost is 1/2 of common fire kilns; the super far infrared timber dryer is safe and convenient to open and stop, and easy to control with rapid and simple operation without additionally installing a boiler.
Description
One, technical field:
The utility model relates to timber drier.
Two, background technology:
The difficulty of timber stoving is that timber variety is assorted, size is big, quantity is many, moisture content is high, and yielding, cracking, shrinkage and warpage, and dries quantity is difficult to assurance.
Large-scale timber dryer is to use steaming process, the volume of stove is big, output is high, can reach the deep layer plank and obtain to optimize the purpose of conducting heat in advance with the moist steam heating, in a single day quality accident appears in dry run, can also squirt and remedy, therefore mostly using steam drying timber, the shortcoming of this method both at home and abroad is that investment is huge, build the boiler room, operational administrative is all very complicated, and the thermal efficiency is low, generally about 30%.
Small-sized drying oven is used fiery pit, wall with flues, vexed kiln and smother-klin etc. always, and arid cycle is long especially, the thermal efficiency is low, difficult quality guarantee.Recently China has developed the hot-blast stove of waste wood piece, chips fuel, but these waste wood pieces and art bits also can be made into particieboard or fiberboard.
Three, summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of super far infrared timber dryer is provided, and is simple and reasonable, cost is low, oven dry cycle weak point, good drying effect, safe and reliable.
The technical scheme that the utility model is adopted for achieving the above object is: super far infrared timber dryer, constitute by operating room and drying chamber, door and external door two storied gate in drying chamber has, be heat-insulation layer between shell body and the inner housing, end face is provided with steam vent, and adjustable plate is equipped with in the steam vent top, the both sides internal face increases from top to bottom successively installs board-like super far infrared heating, pipe type ultra far infrared heating element is equipped with in the bottom surface, and track is housed, and kiln truck can slide in orbit.
Described drying chamber both sides internal face is installed the board-like super far infrared heating of three rows, and quantitative proportion is 1: 2: 3 from top to bottom.
Wire netting is equipped with in described kiln truck bottom.
Described board-like super far infrared heating is the carborundum radiant panel, and the tubular type heating element heater is the metal electric heating pipe.
Through long-term scientific experiment and engineering practice, super far infrared timber drying oven has been compared following advantage with above-mentioned conventional method:
(1) oven dry cycle weak point, general be 1/5～1/3 of steam drying stove arid cycle only with 40～50h, is 1/16 of general coal pit.
(2) quality is good, and is wooden constant after doing, and is easy to processing, and qualification rate is more than 98%.
(3) cost is low, and the oven dry cost is 1/2 of a general fiery kiln.
(4) safety, coal pit or be that fuel all easily catches fire, and sealing around the utility model with the wood chip, moist anoxic in the stove, radiant panel surface temperature are below 400 ℃, and wire netting is arranged at the bottom of dress logging car, prevents that wood chip, bark from dropping on the radiator, all can safety operation.
(5) small investment, go up detective, build a small-sized super far infrared timber dryer for building 1/2 of coal pit drying oven expense, do not need to build in addition boiler, open, stop conveniently, simple to operate, be easy to control.
Four, description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A cutaway view of Fig. 1.
Five, the specific embodiment:
Super far infrared timber dryer has fixed and portable two kinds.Be fixed super far infrared timber dryer as shown in Figure 1 and Figure 2, constitute by operating room 1 and drying chamber 3, door 5 and external door 6 two storied gates in drying chamber is provided with, the furnace chamber volume is generally 2000 * 2000 * Lmm, L is a longitudinal length in the stove, often selects 5m, 7m, 13m for use.Shell body 11 adopts brick one-tenth, angle iron frame, inner housing 12 adopts aluminium sheet to play the reflector effect, be heat-insulation layer 2 between shell body 11 and the inner housing 12, heat-insulation layer 2 is full of heat-insulation and heat-preservation material expanded perlite, thickness is generally greater than 200mm, end face is provided with steam vent 4, discharges moisture naturally, and the steam vent diameter will be through calculating, calculate according to maximum capacity, above steam vent 4, be provided with adjustable plate 10, close usefulness when heating up, so not only conserve energy but also from the humidification augmentation of heat transfer in order to stove, the raising speed section is at the end opened steam vent and is discharged moisture naturally.Because the effect of free convection, hot gas rises naturally, three row's carborundum radiant panels 7 are hung in both sides, and radiant panel is of a size of 250 * 140mm, the 500W48 piece, the most beneath row's wiring is 220V, also because of the top too high measure of taking that easily heats up, as select for use and be the 220VH power supply, radiant panel of these three rows just require to descend most row's dress at most, go up most the minimum of row's dress, the ratio that quantity is installed from top to bottom is 1: 2: 3.24 ∮ 18 * 1260mm of sole arrangement, heat pipe 9 in the 800W metal, and pipe can prevent that the dirt covering from also preventing to catch fire, the bottom surface also is provided with light rail 8, be that kiln truck advances the track of releasing, the kiln truck bottom has wire netting, in order to avoid bark, wood chip piece fall on radiator to catch fire.
The both sides radiator selects for use the SiC plate comparatively suitable, because it is slower that this radiator heats up, more superior than SiC plate radiator as quartz-tube radiator with baking vanish, according to material characteristics, consider to be carried out the selection of radiation and formulate drying process most important by the dehydration characteristics of dried object.
