Embodiment:
Below in conjunction with drawings and Examples the present invention is further described.
As shown in the figure, this skew roller table double-deck furnace mainly comprises loading bay 4, discharge pedestal 1, upper strata live roll 5, lower floor's live roll 2, vacuum chamber 9, body of heater 12 and UTILIZATION OF VESIDUAL HEAT IN heat exchange chamber 14, and described UTILIZATION OF VESIDUAL HEAT IN heat exchange chamber 14 is provided with and stirs blower fan 11.Described upper strata live roll 5 is connected by cross roll road and horizontal roller and forms, be used to transmit upper strata charging basket 6, described upper strata live roll 5 all adopts the cross roll road of same angle at loading bay 4, vacuum chamber 9 and UTILIZATION OF VESIDUAL HEAT IN heat exchange chamber 14 places, and form a charging basket and transmit the cross roll road, changed the pattern of horizontal roller in the past.The gradient of upper strata live roll 5 should guarantee that charging basket can be to lower slip under the deadweight effect.When upper strata live roll 5 rotated, upper strata charging basket 6 can be climbed and be entered vacuum chamber, waste heat switch room.Except charging, discharging is by manually finishing, the F.F. of charging basket with stop, the lifting of Vacuum door, charging basket add heat transfer in two-deck oven, all finish by automatic control program.
Each section live roll in cross roll road independently fast implementation change, close down, action such as constant speed rotation, coordinate each action of control by programmable controller PLC, in the roller-way of slope, the transmission charging basket travelling speed in cross roll road and horizontal roller transmission speed keep synchronously, the charging discharging can not produced get stuck, the generation of situation such as retardance.Lower floor's live roll 2 is formed by connecting by horizontal roller, is used to transmit lower floor's charging basket 3.(also can be that the upper strata live roll adopts horizontal roller, lower floor's live roll 2 adopts cross roll road and horizontal roller to be connected).
Described loading bay 4 and discharge pedestal 1 adopt the two-layer structure of homonymy, body of heater 12 ends are provided with lift material platform 13, upper strata live roll 5, lift material platform 13 and lower floor's live roll 2 constitute the feeding loop, and upper strata live roll 5 and lower floor's live roll 2 are driven by two step-down gears.Described vacuum chamber 9 comprises vacuum chamber Qianmen 7 and vacuum chamber back door 10, and vacuum chamber Qianmen 7 is connected with lifting gear 8 respectively with vacuum chamber back door 10.Vacuum chamber back door 10 1 ends with double-layer furnace body 12 sealed attachment, guarantee the function of forvacuum, inflated with nitrogen and the vacuum air-locked of vacuum chamber.
Principle of work: on the basis of first and second two-deck oven,, begin to UTILIZATION OF VESIDUAL HEAT IN heat exchange chamber end in generation, be improved to the slope by the horizontal roller innovation and upload roller-way, furnace height is descended from loading bay with the upper strata charging transport roller way of two-deck oven.By calculating, the volume of waste heat switch room and vacuum chamber dwindles 1st/3rd, and is feasible.The basic concept of slope roller-way design is: guaranteeing that the load-bearing charging basket can not strengthen the inclined-plane gradient to greatest extent because of conducting oneself with dignity under the condition of roller-way slide down self-locking, makes vacuum chamber and furnace volume compression maximization.Vacuum chamber volume reduces, and the pumpdown time shortens, and inflated with nitrogen is that the nitrogen consumption descends; The volume of UTILIZATION OF VESIDUAL HEAT IN heat exchange chamber reduces, and cold and hot exchange is accelerated, and energy-saving effect improves.In addition, the two-deck oven height also descends to some extent, has brought convenience for operative employee's input and output material, and labour intensity descends.
Automatically the control working procedure is as follows: the annealing part loads onto layered material basket 6 → hang on loading bay 4 → lifting gear 8 startups → vacuum chamber Qianmens 7 and opens → upper strata live roll 5 soon commentaries on classics → upper strata charging basket 6 enter vacuum chamber 9 interior stop → vacuum chamber Qianmens 7 and close → vacuum chamber vacuumizes, inflated with nitrogen → vacuum chamber back door 10 lifting → upper strata charging baskets 6 enter horizontal roller section heating in the oblique roll segments of two-deck oven → UTILIZATION OF VESIDUAL HEAT IN heat exchange chamber → enter stove → by lift material platform → enter isothermal in lower floor's horizontal roller, in slow cooling → UTILIZATION OF VESIDUAL HEAT IN heat exchange chamber → vacuum chamber back door 10 lifting → vacuum chambers 9 stop → vacuum chamber back door 10 close → vacuum chamber Qianmen 7 lifting → lower floor's charging baskets 3 reach on the discharge pedestal 1 soon → upper strata charging basket 6 enters vacuum chamber 9 → vacuum chamber Qianmen 7 and close, and carries out the circulation second time.
Two-deck oven is owing to adopt slope roller-way novel structure, and vacuum chamber volume has dwindled 1/3rd, and nitrogen consumption has also reduced 1/3rd, and mechanism operates steadily, and operation is easy to implement reliable, and labour intensity reduces.
The reduction of UTILIZATION OF VESIDUAL HEAT IN chamber height, volume dwindles, and heat exchange is accelerated, and adds the hot air circulation that stirs blower fan 11, and utilization rate of waste heat has improved more than 5%, has saved energy consumption.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
