The main effect of tar is that materials such as coke powder, silit, clay are combined, and plays the effect of bond.In the process of producing stemming, must accurately measure the flow of tar, make the proportion speed of tar in stemming, thereby guarantee the quality of stemming, keep the normal operation of producing.The measure portion of the oval gear flowmeter that uses at present is made up of two intermeshing oval gears, axle and housings etc.When fluid passes through oval gear flowmeter, because resistance produces pressure reduction, oil pump is produced infringement, how quality of coke tar difference slag just makes oval gear block in addition, and flowmeter can't normally be measured; Next is that oval gear flowmeter, definite value appearance can't verifications, and precision can't guarantee that these have all influenced the normal operation of producing.Therefore it is very necessary designing a kind of volume control device of tar accurately.
The utility model content
The utility model technical matters to be solved provides a kind of device that has highly reliable, high precision, advantage such as applied widely, can adapt to the tar flow control of the interrupted metering of liquid of vicidity.
The technical scheme that solves the problems of the technologies described above is:
A kind of tar volume control device; It is made up of operation and relay board, tar metering control instrument, control fuel tap, LOAD CELLS, flexible connecting member, tar bucket and draining valve; The tar bucket is connected with LOAD CELLS through flexible connecting member; The signal output part of LOAD CELLS is connected with the tar metering control instrument, and the tar jar is through pipeline road and control the oil-in that fuel tap is connected to the tar bucket, and the oil-out of tar bucket is connected to pug mill through pipeline road and draining valve; The control end of control fuel tap and draining valve respectively with operation and relay board on relay be connected, the tar metering control instrument is connected with operation and relay board.
Above-mentioned tar volume control device is parallel with two control fuel taps at the tar jar in the pipeline road of tar bucket, their control end respectively with operation and relay board on relay be connected.
Above-mentioned tar volume control device, the tar jar in the pipeline road of tar bucket, the tar bucket has manual ball valve respectively in the pipeline road of pug mill.
The usefulness of the utility model is: measuring process focusing oil flow non-resistance, and harmless to oil pump, can adapt to current industrial production quality of coke tar situation complicated and changeable, can not carry out smoothly thereby guarantee to produce because of quality of coke tar influences measuring accuracy.The utility model is easy to use, be convenient to maintenance, low cost, high precision, high-level efficiency; Verification is convenient; Can also be applied to the metering of the bigger flowable material of other toughness, overcome the problem that former flowmeter in-situ can't verification, have good social prospect and economic outlook.
