Abstract
The utility model relates to a solid flowmeter in a falling body type, which is composed of a feed-falling pipe, a box body of the flowmeter, and a meter of a microcomputer. A flow rate signal and a weight signal which are collected by two kinds of sensors are sent to the meter of a microcomputer for treatment by the method that the end part of an impeller shaft and the lower surface of a bearing seat are respectively provided with a speed-measuring sensor and a weight sensor, and an impeller is arranged in the box body of a flowmeter; thereby, the purpose of accurately measuring the flow of solid material can be achieved. The utility model has the advantages of high measuring precision, reliable work, cheaper price (just about the 60 percent of the selling price of a flowmeter in a punching plate type), etc. compared with the existing solid flowmeter.
Description
The utility model relates to a kind of falling body type solid flowmeter.
Existing swash plate type solid flowmeter is usually used in measuring the quantity of cement life, grog, but exists because of the unfounded drawback of metering behind the pipeline obstruction.
The purpose of this utility model is to provide a kind of measuring accuracy height, be easy to install, the solid flowmeter of reliable operation, to overcome above shortcoming.
Falling body type solid flowmeter of the present utility model is made up of material blanking tube 1, flowmeter casing 2, microcomputer instrucment 7, it is characterized in that being provided with impeller 3 in the described flowmeter casing 2, impeller 3 is installed on the impeller shaft 4, the end of impeller shaft 4 is provided with tachogenerator 5, impeller shaft 4 is installed on the bearing seat 8, be provided with gravity sensor 6 below the bearing seat 8, be connected for leading between tachogenerator 5 and gravity sensor 6 and the microcomputer instrucment 7.
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model blade wheel structure diagrammatic side view.
Referring to Fig. 1 and Fig. 2 as can be known; material blanking tube 1; flowmeter casing 2; impeller 3; impeller shaft 4; impeller shaft bearing 8; tachogenerator 5; gravity sensor 6; microcomputer instrucment 7; when solid material (particle or powder) when material blanking tube 1 falls; material drops on the right half side blade of impeller 3; cause impeller 3 to rotate toward the clockwise direction; make device be proportional to the photoimpact of wheel speed in tachogenerator 5 outputs of impeller shaft 4 ends; meanwhile; the material gravity that drops on the impeller 3 passes on the gravity sensor 6 by impeller shaft bearing 8; make gravity sensor 6 produce and export the electric quantity signal that is proportional to material quantity; after this rate signal and gravitational cue are delivered to microcomputer instrucment 7 and are carried out computing and handle; just produced the displayed value that characterizes mass flow; this displayed value can be by manufacturing technique requirent; both can be the instantaneous delivery value, also can be the continuous integration value.
The utility model is compared with existing solid flowmeter, has following advantage:
1, certainty of measurement is higher: the Sensor section of this flowmeter, and except the weight letter of having gathered material The flow velocity signal of material also gathered in extra, and these two kinds of signals are delivered to the microcomputer instrucment computing and locate Reason is so effectively avoided the error count phenomenon that occurs because of outlet somewhere clogged up with material.
2, reliable operation: this flowmeter all can be by presetting to what of the size of flow or cumulant High and low place value is sent the audible and visible alarm signal, and alert notes, also can be according to technical process Demand is sent associated external equipment and is opened, stops control signal.
3, price is lower: the price of swash plate type flowmeter is about 20,000 yuan in the market, and the price of this flowmeter only be its about 60%.
Claims (2)
1, a kind of falling body type solid flowmeter, form by material blanking tube (1), flowmeter casing (2), microcomputer instrucment (7), it is characterized in that: be provided with impeller (3) in the described flowmeter casing (2), impeller (3) is installed on the impeller shaft (4), the end of impeller shaft (4) is provided with tachogenerator (5), impeller shaft (4) is installed on the bearing seat (8), be provided with gravity sensor (6) below the bearing seat (8), be connected for lead between tachogenerator (5) and gravity sensor (6) and the microcomputer instrucment (7).
2, by the described falling body type solid flowmeter of claim 1, the blade that it is characterized in that described impeller (3) is respectively at a distance of 45 °.
