Abstract
The utility model discloses a rotary powder material flow meter, comprising an electromotor, a transmission shaft, a torque sensor, a feeding hopper and a measuring dial, wherein, the feeding hopper and the measuring dial are arranged in a sealed housing; a feed inlet is arranged at the upper part of the housing and a discharge port is arranged at the lower part of the housing. The electromotor and the torque sensor are arranged at the outside of the housing. The measuring dial is driven to revolve at high speed by the transmission shaft under the drive of the electromotor. The utility model has the advantages of high precision, compact structure and good tightness. The utility model is suitable for chemical industry, building materials industry, etc.
Description
The utility model relates to a kind of metering outfit of continuous coverage powder material flow, a kind of swinging powder material flowmeter of more specifically saying so.
The continuous measurement of powder material normally adopts impulse flow meter, belt conveyer scale, weightless scale, spiral electronic scales etc.Impulse flow meter is to drop to the flow that the impulsive force that produces on the shock plate is measured powder by measuring powder, and other three is a meterage in weighting equipment.Because powder material has good fluidity, unit weight changes greatly, characteristics such as easy airborne dust, and therefore, the airborne dust that these equipment have is bigger, easily dashes material; The precision in continuous measurement that has is not high; The influence that is subject to the process conditions variation that has needs frequent adjusting and verification.
Characteristics such as the purpose of this utility model is to provide a kind of swinging powder material flowmeter, when realizing powder material high precision continuous measurement, has no dust pollution, and is simple in structure, and volume is little, and is reliable and stable.
The purpose of this utility model is achieved through the following technical solutions.
A kind of swinging powder material flowmeter, include motor, housing, the casing upper half branch has feeder hopper, transmission shaft is installed in the housing, measuring disk is installed on the transmission shaft, is positioned at the feeder hopper below, and measuring disk comprises top board and chassis, there is blanking port at the top board center, there is round table-like baffling awl at the center chassis place, and the guide blade of radially evenly arranging is arranged between top board and the chassis, and the torque sensor two ends link with motor shaft extension and transmission shaft respectively.
Feeder hopper is truncated cone-shaped, and lower ending opening is over against the blanking port at top board center, and the guide blade is 6～12.
In the utility model, material enters housing by charging aperture, and under the effect of feeder hopper, the blanking port that passes the measuring disk top board enters measuring disk, and vertical drop is to the baffling awl that is positioned at the measuring disk center chassis.Measuring disk is turned round with constant angular velocity under the driving of motor by transmission shaft.Under action of centrifugal force, the material that enters measuring disk is along the guide blade measuring disk that speeds away.Leave the material of measuring disk and fall in the housing, discharging opening draws off through the bottom.Torque sensor sends measuring-signal to display instrument, and display instrument shows the instantaneous delivery and the integrated flow of material.
The utility model has been used Coriolis inertial force, and its principle is, the object of any motion in uniform rotation system all is subjected to the effect of Coriolis inertial force, when relative velocity for radially the time, Coriolis force is tangentially.The vector expression of Coriolis inertial force is Fc=-2m ω * υ ', and m is a quality in the formula, and ω is an angular velocity, and υ ' is a relative velocity.When measuring disk is turned round with constant angular velocity, material along the guide blade in measuring disk to outside the material that moves just uniform rotation system, do radial motion, therefore, material also is subjected to the effect of tangential Coriolis inertial force when being subjected to radial centrifugal force and reverse friction force effect.The moment that this inertial force produces makes measuring disk transmission shaft generation change in torque.According to moment of torsion and moment, the relation of moment and Coriolis inertial force.The mass rate that can derive moment of torsion and material is proportional.Can obtain the mass rate of material by the change in torque of measuring transmission shaft.Therefore, the utility model is measured as the basis with quality of material.
The utility model compact conformation, volume is little, and metering process is finished in housing, and there is not dust pollution question in good airproof performance, and the continuous measurement precision is better than 0.5%.Can be widely used in the batching and the metering of powder material in the industrial processs such as chemistry, cement, the metering outfit that also can be used as in the powder material sales process in bulk is used.

Below in conjunction with accompanying drawing,, the utility model is further described by embodiment
Embodiment:
Referring to Fig. 1, Fig. 2, Fig. 3.The utility model has housing 2, measuring disk 7, and transmission shaft 12, feeder hopper 3, torque sensor 11 has charging aperture 1 and discharging opening 10 on the housing 2.Torque sensor 11 and motor 8 are positioned at housing 2 outer tops, and are bearing on the housing 2.The two ends of torque sensor 11 link with motor 8 shaft extensions and transmission shaft 12 respectively.Transmission shaft 12 is by bearing seat 13,14 supportings, and measuring disk is positioned at housing 2, is fixed on the transmission shaft 12.Measuring disk is made up of top board 4, chassis 5, guide blade 9 and baffling awl 6.Top board 4 and chassis 5 equal diameters, the top board center has blanking port 15.Guide blade 9 has 12, is radially to be evenly arranged between top board 4 and the chassis 5, and top board 4 and chassis 5 are fused, and makes and forms 12 material channels in the measuring disk.Baffling awl 6 is positioned at 5 centers, chassis, is round table-like.Feeder hopper is reverse frustoconic, and the upper end is fixed on top in the housing 2, and lower ending opening is over against the blanking port 15 at measuring disk top board 4 centers.
