Background technology
Solid flowmeter is measured as the continuously online load-bearing that sand etc. provides for the dry loose unpacked material of flow, its principle is to utilize momentum principle to detect the solid material weight such as bulk, graininess and powdery of whereabouts, existing Clashing-plate Type Solid Flowmeter adopts running gear, external vibration is large on the impact of measuring, if environment is severe, material sticks on check-out console, can be influential to measuring accuracy.
Summary of the invention
For above shortcomings part in prior art, the plate type solid electronic flow-meter that provides a kind of measuring accuracy high is provided the problem to be solved in the present invention.
The present invention adopts following technical scheme:
A kind of plate type solid electronic flow-meter, comprise housing, diversion trench, check-out console and device for measuring force, and wherein check-out console tilts to be placed in housing, and the upper end of check-out console is hinged in rotating shaft, and lower end is free end; Diversion trench is arranged at the upper end of housing, with check-out console, communicates; Device for measuring force is placed in the check-out console bottom surface back, and it is vertical with the check-out console bottom surface that the power of device for measuring force is transmitted bar.
Described device for measuring force comprises that power is transmitted bar, the power that is set in is transmitted the orienting sleeve on bar and transmits with power the sensor that bar is connected.
Described power is transmitted bar and is had force transmission shaft I and force transmission shaft II, and power is transmitted bar and contacted with the check-out console bottom surface by force transmission shaft II, by force transmission shaft I, with the power sensor, is connected, and force transmission shaft II mono-end is inserted in force transmission shaft I, by tightening nut, fixes.
Orienting sleeve and power are transmitted between bar and are provided with the O-ring seal sealing.
Check-out console and horizontal line angle α are 60 °-80 °.
Angle β between diversion trench and horizontal line is 60 °-80 °.
Described power sensor is beam type power sensor.
Principle of the present invention: material is Dinged in certain altitude mono-on Pour angular flux inbound traffics check-out console, check-out console is the hinged hang plate of an end, dynamometer is installed after check-out console, ergographic dynamometer link is perpendicular to check-out console, material is that the speed of fixing flows on check-out console in a stable device, get constant speed in electronic measurement. due to the effect of diversion trench, material is similar to tangential inflow check-out console, has reduced the impulsive force to check-out console. the relational expression of the normal pressure that material detects at the gravity of check-out console and sensor:
N=K*Mg*cosα
The M-quality of material.
α-check-out console and horizontal line angle are definite value.
K-leverage factor (being constant)
Visible quality of material is directly proportional to normal pressure, by detection power, through computing machine, calculates, and just can know instantaneous delivery and cumulative amount.
The present invention has following advantage and beneficial effect:
Be suitable for flow and the cumulative amount of the bulk solids material that on-line measurement freely falls, measuring accuracy is high, and the dynamic measurement precision is generally 0.5%, reaches as high as 0.25%, is the ideal product that replaces Clashing-plate Type Solid Flowmeter; After demarcation, can use for a long time, anti-interference, a little repair, can be used for the industry batching, and measuring raw materials, realize On-line Control, is widely used in the industries such as cement, coking, mine, petrochemical complex, port traffic, metallurgy, power plant, grain.
The present invention is simple in structure, without running gear, adopts beam type power sensor, external installation.The check-out console good stability, impact resistance is strong, and vibration is less on detecting impact, can under the condition severe at environment, work.Material sticks on check-out console, and accuracy of detection is had to certain influence, in sticking property, on stronger material, does not use as far as possible.Equipment occupation space is little, and the space of 1.5M left and right can be installed.
