Principle of work of the present utility model is:
The utility model is combined by two groups of symmetric each other split batch chargers of structure as seen from Figure 1, Figure 2.
The utility model adopts split type frame.All parts such as two material-feeding shovels and corresponding two cover transmission mechanisms, feed bin are separately fixed on two frames, and each frame lower respectively has a cover wheel assembly, links to each other with clutch coupling with universal joint in the middle of the two cover transmission mechanisms of equipment.Below set forth principle of work of the present utility model by being provided with of structure.
Transmission system: adopt frequency transformer that the rotating speed of alternating-current variable frequency motor is controlled, electric machine speed regulation scope 1:10 guarantees reciprocating frequence stepless speed regulation between 0.45-4.5r/min of material-feeding shovel operation.Cooperate glass liquid level nucleon instrument to realize the automatic control of charging capacity, the liquid surface height controlling precision can reach ± 0.25mm.Two cover driving terminals can guarantee by the combination of three clutch couplinges: 1) driven by a cover driving terminal, can realize two material-feeding shovel synchronous operations, prevent inclined to one side material effectively, and for this quantity-produced main equipment, can realize that driving terminal is standby each other.2) two material-feeding shovels also can be driven respectively by two driving terminals in case of necessity.Taked the electrical equipment control of multichannel protection in addition, reached two driving terminal interlock protections, prevented that the people from being the destruction of mishandle to equipment.
The pneumostop device: batch charger leaks material and not only influences the kiln hood operating environment, also easily causes the wearing and tearing and the blocked portion of equipment self.This device has solved this difficult problem effectively.Material scraping plate lifts when material-feeding platform travels forward by the drive of cylinder, falls when moving backward, both can prevent the leak-stopping material effectively, can reduce the wearing and tearing between material scraping plate and the material-feeding platform surface again.The adjusting screw(rod) on cylinder top can compensate the wearing and tearing of material scraping plate easily.
Material-feeding shovel: 10 ° ± 2 ° angles of two groups of relative horizontal planes inclinations of material-feeding shovel are provided with, when material-feeding shovel moves forward, the material that floats on the metal level in the pond that feeds intake is pushed away forward, and the trend that is pressed into liquid arranged, material in the feed bin is descended by action of gravity simultaneously, and is subjected to gatage to be controlled at material-feeding shovel table top upper berth generate one book layer.When material-feeding shovel moves backward, the pneumostop device at feed bin rear portion falls, simultaneously because the effect of material pressure in the feed bin, material on the material-feeding shovel is not with moving behind the material-feeding shovel, but and produce slippage between the material-feeding shovel, fall into successively in the pond that feeds intake, the continuous to-and-fro movement of material-feeding shovel makes admixtion continuously send into glass melter.The pond contacts because the front end of material-feeding shovel and 800 ℃ of pyritous feed intake, thereby to the very high requirement of resistance toheat proposition of pushing plate.Overseas equipment generally is provided with air-cooled or water-cooling system to improve the work-ing life of pushing plate at the pushing plate place, consider air cooling system noise, dust pollution and water-cooling system easy to leak and to problems such as water quality requirement height, the utility model adopts homemade high-quality Heat resisting cast steel as the pushing plate material, it is high temperature resistant can to reach 950 ℃, has cancelled cooling system.
Material-feeding shovel wheel holding mechanism, swing-bar mechanism and toggle: material-feeding shovel is done iterative motion under the drive of linkage assembly, and its bottom surface is supported by several support rollers.The swing bolt at support roller rear portion and nut make each support roller all can keep excellent contact with the material-feeding shovel bottom guide track in order to adjust the support roller height; Support roller has adopted self-lubricating plain bearing, its favorable mechanical performance can guarantee that wheel holding mechanism adds in high temperature, high-load and nothing under the operating mode of lubricant and run well, avoided not changeing, and produced the phenomenon of metal to-metal contact between the guide rail because of insufficient lubrication causes support roller.The length similar with wheel holding mechanism, that swing-bar mechanism intermediary screw-nut body is used to regulate fork, thus further the pitch angle of material-feeding shovel is controlled, adjust the length of fork and the absolute altitude of support roller simultaneously and can also control the absolute altitude of material-feeding shovel.Toggle drives the to-and-fro movement of material-feeding shovel, and three eccentric orfices on the disk are corresponding to three different crank length, and the length of material-feeding shovel stroke approximates the twice of crank length.
Bin stopper and regulating mechanism thereof: the aperture of bin stopper is an important parameter of batch charger, and its effect is the thickness of the control bed of material and prevents inclined to one side material.The lifting of gate drives by pinion and rack, because higher being not easy to of this place temperature operate, is located at the feed bin rear portion so driving handle changed, and transfers a torque to front end by a major axis.In order to reduce driving moment, improve the stressing conditions of major axis, increase primary gear speed reducing and itself and pinion and rack are merged into an independently rack-and-pinion case at front end again.For anti-locking mechanism is heated stuckly, all adopted self-lubricating plain bearing in the case, rack-and-pinion is brushing ability pyritous high-performance seizureproof agent more than 1000 ℃ before assembling, and the casing front also has the insulation plate protection.The place is provided with scale card at handle, is convenient to accurately regulating gate aperture of operator.Present many batch chargers are to come the regulating gate aperture in the side by the operating crank linkage assembly, and by contrast, this cover mechanism operation is more flexible, and the adjusting aperture is more accurate.
