Abstract
The utility model discloses a ring-shaped metering scale and belongs to a metering device. A housing (1), a power device, a rotating mechanism and a sensing device are comprised; the housing (1) is fixed on a machine frame (2) through at least two fulcrums, and a feed opening (3) and a discharge opening (4) are formed on the housing (1); the rotating mechanism is mounted inside the housing (1) and is fixedly connected with the output part of the power device; the rotating mechanism is formed by a plurality of fan-shaped blades (6) fixedly mounted on a rotor core shaft (5); and the sensing device and a counterweight device (7) are mounted on the side surface of the machine frame (2). Through arranging the fan-shaped blades in the housing along the horizontal direction, a fan-shaped accommodating cavity is formed inside the housing under the action of the fan-shaped blade structures, and pulverized coal matched with the accommodating cavity directly enters into the fan-shaped accommodating cavity through the feed opening on the housing, solving the extrusion and fluctuation problems of the pulverized coal in the housing and improving precision of the metering scale. In addition, with compact design of all parts and smaller volume, the metering scale is suitable for more occasions.
Description
Technical field
The utility model relates to a kind of measuring apparatus, a kind of ring balance weigher of saying so more specifically.
Background technology
In present building materials are produced, being used for coal powder metering in its rotary kiln combustion system all is spiral metering scale usually, its primary structure comprises spiral gate, screw feeder, spiral measurement sensory device and injection induction system composition, adopt this kind structure because there is defective in screw axis self, also can depart from about 5% to 10% of standard value even under normal situation, play the metering difference, though solved the problem of rotary kiln combustion system coal dust continuous measurement, but because its accuracy is relatively poor, cause the interior temperature difference of kiln big, influence cement clinker quality.Can not satisfy the demand of growing coal dust calcining industry, and traditional weighing balance complex structural designs, its volume is bigger, and is bigger to the limitation of its field of employment.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency, provides a kind of pinpoint accuracy and volume less a kind of ring balance weighing balance.
For solving above-mentioned technical matters, the utility model by the following technical solutions:
Ring balance weigher of the present utility model comprises housing, propulsion system, and rotating mechanism and sensing device, housing is fixed on the frame by at least two fulcrums, and its top is provided with charging aperture and discharging opening; Rotating mechanism is installed in the housing and with the output of propulsion system fixedlys connected, described rotating mechanism is to be made of a plurality of sectors that are fixed in the rotor mandrel, the side of frame is equipped with sensing device, and the opposite of sensing device is equipped with counter weight device.
Further technical scheme is: described sector level is fixed in the rotor mandrel.
Further technical scheme is: the discharging opening on the described frame also is connected with surge bunker.
Further technical scheme is: described propulsion system are made up of motor and speed reduction unit, and speed reduction unit is fixed on the output shaft of motor.
Further technical scheme is: described sensing device is made up of LOAD CELLS and speed pickup.
Further technical scheme is: described speed reduction unit is fixedlyed connected with rotor mandrel.
The utility model is all right: be provided with O-ring seal between described speed reduction unit and the rotor mandrel.
Compared with prior art, the beneficial effects of the utility model are: by in the housing along horizontally disposed sector, under the effect of sector structure, can form fan-shaped chamber volume in the inside of housing, the coal dust supporting with it directly enters fan-shaped chamber volume along the charging aperture on the housing, the extruding and the fluctuation of coal dust in the housing have been overcome, cooperate the degree of accuracy that has improved weigher with the LOAD CELLS of housing side, its each Component Design compactness of while, good airproof performance, volume is less, reach environmental requirement, be fit to more places and use.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 1 and Figure 2, ring balance weigher of the present utility model, comprise housing 1, propulsion system, rotating mechanism and sensing device 8, sensing device 8 is made up of LOAD CELLS and speed pickup, propulsion system preferentially are made up of motor 10 and speed reduction unit 11, and speed reduction unit 11 is fixed on the output shaft of motor 10, and housing 1 is fixed on the frame 2 by at least two fulcrums, and its top is provided with charging aperture 3 and discharging opening 4, and discharging opening 4 also is connected with surge bunker 9; Rotating mechanism is installed in the housing 1 and with the output of propulsion system fixedlys connected, described rotating mechanism is to be made of a plurality of sectors 6 that are fixed in the rotor mandrel 5, sector 6 preferential levels are fixed in the rotor mandrel 5, rotor mandrel 5 fixedlys connected with the output shaft of speed reduction unit 11, and between its rotor mandrel 5 and the speed reduction unit 11 O-ring seal is arranged, the side of frame 2 is equipped with sensing device 8 and counter weight device 7, sensing device 8 and two opposites of counter weight device 7 in frame 2.
The design of the rotor scale housing 1 center line outside has two fulcrums, and import and export 3 are arranged on the same center line of two fulcrums with discharging opening 4, constitutes ring texture.A plurality of sectors 6 that are fixed in the rotor mandrel 5 form fan-shaped chamber volume in housing 1 inside, and coal dust is evenly imported each sector shaped chamber by ration feeding machine.When coal dust enters the rotor scale, in housing 1, be interior half circular motion, produce the load pulling force that is proportional to material by housing 1 in the skew of the centre of gravity place of frame 2.LOAD CELLS provides electric signal with the material direct ratio with this pulling force signal to control system, and speed pickup is installed on the motor 10 by Frequency Converter Control, tach signal is also offered the control system that matches with the balance weighing balance, system carries out integral operation with these two signals, calculate PV value (flow), control to the frequency converter of balance weighing balance and ration feeding machine by system, PV value and SV (setting value) are consistent, charging aperture 3, discharging opening 4 is connected all with the connection of outside other equipment that employing is flexible coupling, and guarantees that measuring accuracy is not subjected to ectocine.
