Embodiment
As shown in Figure 1, 2, the utility model is a kind of retort furnace angular adjustment apparatus, in Fig. 2, can also see edge wheel 7 and roller 8, upper surface at overflow groove housing 2 is equipped with at least four tops adjustment suspension systems 3, each top is adjusted suspension system 3 and all is connected with the suspension basis 4 (for example hang the basis and be girder steel fixed but that have the certain level adjustment capability) of overflow groove housing 2 tops, thereby overflow groove housing 2 is sling; And passive lower unit 5 is equipped with at least four bottom setting devices 6 below overflow groove housing 2, thereby overflow groove housing 2 is supported.
As shown in Figure 1, 2, specifically be separately installed with four tops at four angles at overflow groove housing 2 upper surfaces and adjust suspension system 3, and be separately installed with four bottom setting devices 6 at four angles of lower unit 5 upper surfaces.Four tops are adjusted suspension system 3 and are adopted helical riser, cylinder, hydro-cylinder, leading screw or lever hoisting appliance, and four bottom setting devices 6 adopt helical riser, cylinder, hydro-cylinder, leading screw or lever hoisting appliance.
Embodiment 1:
For slope adjusting device, carried out preliminary explaining in the following embodiments, but it does not limit the protection domain of patent.
At first, in installation process, carry out respectively independent adjustment for the level of overflow groove housing 2 and the level of lower unit 5, guarantee the basal level of this two portions equipment.As shown in Figure 3, in the utility model, create a qualified temperature field by overflow groove housing 2 carrying overflow grooves 1 and for it.Four jiaos of overflow groove housing 2 are separately installed with a top and adjust suspension system 3, top is adjusted suspension system 3 and is rigidly connected with suspension basis 4, (namely can rotate around arbitrary axis at tie point and adopted universal the connection between upper suspension setting device 3 and the overflow groove housing 2, but displacement that can only be limited), so just formed a firm connection.
Use this device can reach two targets:
Target one: reduce the manufacturing accuracy requirement for each several parts such as overflow groove housing 2 and overflow grooves 1.Because the upper suspension setting device in four bights can independently moving.In installation process, undertaken accurate adjusting separately by the upper suspension setting device for four bights, can guarantee after installation work is complete 1 of overflow groove with respect to the horizontal plane levelness good on both direction.
Target two: carry out trickle adjustment for the overflow parameter in the operational process, the erosion for overflow groove 1 compensates for the error in the manufacturing processed and long-time condition of high temperature lower-glass liquid.Can not finish manufacturing according to the qualified data of theory fully in the manufacturing processed, and this trickle acceptable defective is probably along with the prolongation of working time, defective is constantly amplified, and causes the decline of overflow quality.
At this moment, in the situation that overflow groove 1 quality own does not reach capacity, can link and adjust the upper suspension setting device of adjacent corners, so that the processing parameters such as inclination angle of overflow groove 1 obtain compensation to a certain degree.As shown in Figure 3, two upper suspension setting devices of overflow groove 1 minor face are adjusted in simultaneously interlock, can compensate the inhomogeneous erosion that overflow groove 1 is gone up along its length; Two upper suspension setting devices on overflow groove 1 long limit are adjusted in simultaneously interlock, can compensate the inhomogeneous erosion on overflow groove 1 broad ways.Concrete equalising means is as follows:
As shown in Figure 3, because overflow groove 1 length direction is identical with the inflation method of width, only enumerate in the present embodiment the adjustment example of overflow groove 1 width.
When the overflow parameter of overflow groove 1 width is bad.The serious uneven situation of glass metal that the right and left overflow can occur, when the most serious, the single face cutout can appear, can't guarantee that like this sheet glass of producing has good surface quality, at this moment, can carry out the inclination of certain angle to overflow groove 1, as shown in Figure 3, the method that adopts is two tops adjustment suspension systems 3 that link simultaneously and adjust one side, so that about produce the difference of altitude that value is x, because the spacing y of two point of tangent has unique fixed value after the equipment design construction is complete, the offset angle that produces so in this case is: a=arctg (x/y).
In the system that lifting is accurately controlled, for example in the system that the lifting distance that adopts PLC or other industrial control unit each top to be adjusted suspension system 3 is accurately controlled, can set its parameter, can set input value is parasang (such as mm), and also can set the input unit is angle (such as degree).On output valve, also can set equally its displayed value and be distance or angle value.
Identical with compensation way on above-mentioned overflow groove 1 width for the compensation of the angle of inclination of overflow groove 1 length direction.After over-compensation, can improve the overflow quality of glass metal, prolonged to a certain extent the duration of service of overflow groove 1 simultaneously, reduced production cost.
As shown in Figure 3, adopt and use the same method, when having adjusted overflow groove housing 2 angles, can obtain the angle that lower unit 5 tilts, because the spacing of lower unit 5 point of tangent is known, also can calculate corresponding adjustment size, and in time follow-up is adjusted, namely pass through to adjust the lifting distance between four bottom setting devices 6, thereby avoid the not good detrimentally affect for producing of lower unit 5 levels.Clearly, this moment overflow groove housing 2 with lower unit 5 between adopted the soft sealing means that is connected.
