Embodiment
The total design of the utility model adds scraper plate at the transmitting terminal of radar level gauge, prevents dust to be stained with and hang and report by mistake.Two kinds of embodiments are introduced below in conjunction with accompanying drawing.
The first embodiment: as shown in Fig. 1 Fig. 2, the anti-error radar level gauge 2 of this dedusting comprises main frame 3 and transmitting terminal 4, is characterized in: the transmitting terminal 4 of described radar level gauge 2 is provided with a scraper plate 5 below.Composition graphs 3 Fig. 4 Fig. 5 is visible: one end of scraper plate 5 is connected with the rotating shaft 6 of setting, rotating shaft 6 is through axle sleeve 7 and the transmission of engine phase, the axis of axle sleeve 7 parallels with the axis of radar level gauge transmitting terminal 4, scraper plate 5 its coboundary in the rotation with rotating shaft 6 nuzzles up the transmitting terminal 4 of radar level gauge, namely with the friction of transmitting terminal 4 phase.Here the engine driving scraper plate 5 to rotate can be motor 8, and the power output shaft of motor 8 enters speed reduction unit 9, and speed reduction unit 9 switches through axle 6 downwards again, and rotating shaft 6 is through axle sleeve 7, and axle sleeve 7 is arranged on support 1.The main body of support 1 is a discoid plate face, middle installation radar level gauge 2.The main frame 3 of radar level gauge 2 is on support 1, and its transmitting terminal also claims antenna to be bell mouth shape, in the below of support 1.
During use as shown in Figure 6, anti-error for this dedusting radar level gauge is arranged on the suitable for reading of coal store 10 by support 1, and coaling machine 11 carries coal to coal store 10.Coal store 10 also may have the outlet exporting coal, because belonging to conventional structure, therefore does not draw.During work, motor 8 drives rotating shaft 6 and scraper plate 5 to slowly run, interval through transmitting terminal 4, the dust that transmitting terminal 4 is stained with extension can be wiped off, therefore radar level gauge would not have been reported by mistake.
The anti-error radar level gauge of dedusting that the second embodiment: Fig. 7 introduces, substantially identical with the structure of the first embodiment, also comprise frame 1 and radar level gauge 2, radar level gauge 2 comprises main frame 3 and transmitting terminal 4, the frame 1 of the side of radar level gauge 2.The transmitting terminal 4 of radar level gauge 2 is provided with a scraper plate 5 below.One end of scraper plate 5 is connected with the rotating shaft 6 of setting, rotating shaft 6 through axle sleeve 7 and the transmission of engine phase, scraper plate 5 in the rotation with rotating shaft 6 with the friction of transmitting terminal 4 phase.Difference is: the power driving scraper plate 5 to rotate here is not motor, but pneumatic motor 12.The form of pneumatic motor 12 is a lot, the wind-force pneumatic motor of to be a kind of with natural wind the be power exemplified in figure.As shown in the figure, this pneumatic motor 12 has a wind wheel 13, and wind wheel 13 drives air pump 14 by vertical shaft, and air pump 14 is connected with accumulator 16 by retaining valve 15, and accumulator 16 is relative with impeller 18 by constant pressure valve 17, and impeller 18 is arranged on the upper end of rotating shaft 6.
During work, wind wheel 13 rotates under the promotion of natural wind, air pump 14 is driven to fill air to accumulator 16 by vertical shaft, when the air pressure in accumulator 16 reaches setting value, spring-compressed in constant pressure valve 17 and opening, gases at high pressure are gone out, promote impeller 18 drive rotating shaft 6 and scraper plate 5 to rotate fast, radar level gauge make a start 4 dust force wipe off.Due to accumulator 16 exit after in pressure reduce rapidly, constant pressure valve 17 cuts out, and rotating shaft 6 stops operating.When the pressure in accumulator 16 increases to over constant pressure valve 17 set pressure again, repeat above-mentioned action.Because coal store 10 is all higher, the natural wind of upper end is all larger, is enough to the need of work meeting scraper plate 5.Particularly there is accumulator 16, certain pressure can have been stored, when the abatement of wind or short time do not have wind, also can continuous firing a period of time.Experiment proves, this step cleaning mode is very suitable for the operation of coal store radar level gauge, and does not need power consumption, and operating cost is very low, achieves beyond thought effect.
The third embodiment: as shown in Figure 8, on the basis of the second embodiment, adds a throttling valve 19 and a quantitative pot 20 between accumulator 16 and constant pressure valve 17.Here throttling valve 19 can adopt the simplest little ports valve, what make the gas slowly in accumulator 16 enters quantitative pot 20, when the pressure in quantitative pot 20 is greater than the opening pressure of constant pressure valve 17, acting can be gone out, promoting scraper plate 5 works in a moment, due to follow-up gas flow interruption, constant pressure valve 17 temporary close, scraper plate 5 completes one-time dedusting action.Just action next time can be carried out after the air pressure in quantitative pot 20 accumulates again.Due to the restriction of throttling valve 19, accumulator 16 carries the speed of gas very slow to quantitative pot 20, even if empty inside quantitative pot 20, the working pressure that reach next time also needs the longer time.Obviously, this mechanism can make to keep higher pressure reduction between accumulator 16 and quantitative pot 20, can the normal work of maintenance scraper plate of longer time after once storage pressure.
4th kind of embodiment: as shown in Figure 9, be provided with bristle 21 on the upside of scraper plate 5.Bristle 21 can be made with various resilient filament, the upper end of bristle 21 should higher than the end face 1-2mm of transmitting terminal 4, time bristle 21 turns over transmitting terminal 4, more bending namely by, so both can keep larger wiper pressure, the installation accuracy of scraper plate 5 can be reduced again, increase the serviceable life of scraper plate 5.
