Abstract
The online measuring device for mass flow rate of material of the utility model is used for powder material and solid particle material novel spring plate suspension impact plates and force-transferring in a machine conveying system. The utility model mainly comprises a diversion slot, an impact plate, a force-transferring spring plate, a pressure sensor, a set of weights, two sets of rolling bearings and a casing. The diversion slot is arranged on one side of the casing, the lower opening of which is opposite to the vertical suspending impact plate which is fixed by a suspending spring plate. The force-transferring spring plate, which is horizontally connected with the stress end points of the pressure sensor, is installed at the lower end of the impact plate. The signals detected by the pressure sensor are processed in a micro processing control unit through the cable. The zero point and the full point marks of flow rate measurement adopt a mode that one end of the thin wires of the rolling bearings supported by the supporting parts are connected with the pressure sensor and the other end is connected with the weights. The utility model has the advantages of high measuring precision, high reliability and good stability and is suitable for the measurement of solid particle material and powder material. In order to solve powder material online motion measurement in the industries of food, feedstuff, cement and chemical, a new device with high performance is provided.
Description
The utility model belongs to measurement mechanism, particularly a kind of novel material mass rate on-line measurement device that is used for granular material and solid particle material in mechanical induction system.
In many commercial processes, the mass flow on-line measurement is particularly important, it directly affects the operation conditions of material technology and the quality of product, begun since the impact flow meter of measuring flow of solid material comes out from the eighties, many producers have begun to use, but,, uses existing impact flow meter so being influenced only for measuring at solid particle material by its structure and dynamometry mode owing to the flowability difference of granular material and easily attached to punching and measuring body surface.
The purpose of this utility model is to overcome above-mentioned defective, and a kind of measuring accuracy height is provided, good reliability, and good stability, it not only is suitable for granule materials and measures and be applicable to the novel mass rate on-line measurement device that granular material is measured.
The technical solution of the utility model realizes as follows: a kind of novel material mass rate on-line measurement device, it mainly contains diversion trench, punching, the power transmission reed, pressure transducer, hang reed, fixture, counterweight, two suit rolling bearings and cabinet, diversion trench is loaded on cabinet one side, the lower port of its diversion trench is over against the punching that is hung the reed vertical hanging by fixture, the power transmission reed that is loaded on the punching lower end is connected with the stressed end points level of pressure transducer, send into little processing controls parts by the pressure transducer measured signal by cable and carry out data processing, adopt with the demarcation of full load the zero point of flow measurement and be connected with pressure transducer by thin cable one end on two suit rolling bearings of supporting members support, the other end is connected with counterweight, and diversion trench lower end runner is designed to inclined-plane or curve form in addition.
The upper port of above-mentioned diversion trench is equipped with the cowling panel of the certain angle that has a down dip; Described suspension reed can be that single-point, multiple spot or many groups hang the punching mode in addition.
Characteristics of the present utility model are: the horizontal component F2 that only surveys punching, measuring accuracy is not pulled the influence that material adheres to or the punching deadweight changes, the design of diversion trench and cowling panel constitutes the supplied materials that can adapt to various angles, height and variety of way, the pressure transducer force transferring part adopts flexible reed to connect, it is minimum that the influence that factors such as pressure transducer is installed, vibration are produced reduces to, its stable equipment operation, long service life, the reliability height, be suitable for the granular material that free flowable material comprises that free flowability is relatively poor or adhesion is stronger, more extensive.
Below in conjunction with drawings and Examples in detail the utility model is described in detail:
Accompanying drawing 1, structural representation of the present utility model;
Accompanying drawing 2, principle schematic of the present utility model.
Among the figure: 1 counterweight, 2 power transmission reeds, 3 pressure transducers, 4 punchings, 5 hang reed, 6 feeding mouths, 7 diversion trenchs, 8 discharging openings, 9 cabinets, 10 pairs of suit rolling bearings, 11 cowling panels, 12 little processing controls parts, 13 fixtures.
As shown in Figure 1, material is flowed into through cowling panel 11 bufferings by feeding mouth 6, passage be the diversion trench 7 of curve form material is glided strike with mass flow direction punching 4 at an angle on, material and punching 4 bump bounce-back backs flow into next procedure by discharging opening 8, material is when the water conservancy diversion notch of flowing through rushes at punching 4 when the time comes, the kinetic energy that material obtained of cross-sectional distribution roughly the same (as shown in Figure 2) punching 4 at this moment is subjected to one and the proportional impulsive force F of mass flow of materials, by hang reed 5 with vertical stress component with sponging, horizontal component F2 is delivered on the stress point of pressure transducer 3, the little processing controls parts 12 that are connected with pressure transducer 3 by cable calculate material instantaneous delivery and integrated flux again, the relation of pressure and mass rate then is a nonlinear function, and the error that calculates is minimum.Punching 4 is hung vertically on the fixture 13 by hanging reed 5, the swing that punching produces horizontal direction to the greatest extent when material impacts punching 4 like this, the stressed F1 of its vertical direction is then absorbed by fixture 13 by hanging reed 5, and pressure transducer 3 is surveyed and only is the power F2 of horizontal direction, the 3 one-tenth levels of power transmission reed 2 and pressure transducer that are vertically fixed on the punching 4 are connected, make horizontal force F2 effectively pass to pressure transducer 3, the influence of vibration that punching 4 is produced and vertical forces simultaneously reduces to minimum.The runner of diversion trench 7 is designed to curved surface or inclined-plane, has bigger horizontal direction momentum when making material flow out diversion trench 7, then make punching obtain big as far as possible horizontal component sword, the cowling panel 11 of diversion trench 7 settings suitable for reading can guarantee effectively that solid matter streams is not subjected to short transverse, the variable effect of the initial momentum that labile factors such as fluidised form are brought, guarantee the consistance of streams inlet initial velocity, adopt two suit rolling bearing 10 supporting thin cables one ends to hang structure that the counterweight other end with pressure transducer be connected with the demarcation of full scale point the zero point of flow control, make demarcation more simple and easy to do, guarantee precision and consistance.
The utility model is applicable to the mass flow measurement of solid material, opened up the new method of granular material flow with the punching on-line measurement, for providing volume little in the field production technologies such as grain, chemical industry, cement, the precision height, practicality is good, online granular material and solid particle material flow metering that price is low newly design, and have use value preferably, and can produce good economic benefits and social benefit.
