Abstract
A kind of flow control for high position tank dropping and supervisory system, flow control and supervisory system comprise pressure-type liquidometer (2), electromagnetic flowmeter (3), pneumatic control valve (4) and PLC (5), the discharge port of high position tank (1) is communicated with the material feeding mouth of material pot 7 by pipeline (6), pressure-type liquidometer (2), electromagnetic flowmeter (3) and pneumatic control valve (4) are arranged on pipeline (6) respectively successively, and pressure-type liquidometer (2), electromagnetic flowmeter (3) are connected with PLC (5) respectively with pneumatic control valve (4).The utility model advantage is: the control mode using pressure-type liquidometer, flowmeter, air brake valve and PLC to combine, realize instantaneous flow and flux cumulating value accurate control.
Description
Technical field
The utility model relates to Chemical Manufacture processing and supplementary equipment field, is specifically related to a kind of flow control for high position tank dropping and supervisory system.
Background technique
At present, on existing domestic chemical production line, the mode of flow control when dripping material by high position tank in reactor has following several approach: one, with a common ball valve, manually calculate flow with manual time-keeping, then regulate ball valve to control the mode of flow; Two, mounting glass rotameter, by the mode of range estimation rotameter flow indication, the mode of manual tune ball valve carries out flow control.Not only flowed fluctuation is more for these two kinds of methods, and the flow calculating out also have larger error.Control mode more just carries out ball valve control cursorily, and flow accuracy is the highest can only reach 5%, and this brings great interference to the stability in production process.
Model utility content
The purpose of this utility model is exactly have following several approach for the mode that current flux controls: one, with a common ball valve, manually calculate flow with manual time-keeping, then regulates the mode of ball valve control flow; Two, mounting glass rotameter, by the mode of range estimation rotameter flow indication, the mode of manual tune ball valve carries out flow control.Not only flowed fluctuation is more for these two kinds of methods, and the flow calculating out also have larger error.Control mode more just carries out ball valve control cursorily, and flow accuracy is the highest can only reach 5%, and this brings the deficiency of interference greatly to the stability in production process, and provides a kind of flow control for high position tank dropping and supervisory system.
The utility model comprises high position tank, it also has flow control and supervisory system, flow control and supervisory system comprise pressure-type liquidometer, electromagnetic flowmeter, pneumatic control valve and PLC, the discharge port of high position tank is communicated with the material feeding mouth of material pot by pipeline, pressure-type liquidometer, electromagnetic flowmeter and pneumatic control valve are arranged on pipeline respectively successively, and pressure-type liquidometer, electromagnetic flowmeter are connected with PLC respectively with pneumatic control valve.
The utility model advantage is: the control mode using pressure-type liquidometer, flowmeter, air brake valve and PLC to combine, realize instantaneous flow and flux cumulating value accurate control.

Fig. 1 is the utility model structural representation.
Fig. 2 is utility model works functional-block diagram.
Embodiment
As shown in Figure 1, 2, the utility model comprises high position tank 1, it also has flow control and supervisory system, flow control and supervisory system comprise pressure-type liquidometer 2, electromagnetic flowmeter 3, pneumatic control valve 4 and PLC 5, the discharge port of high position tank 1 is communicated by the material feeding mouth of pipeline 6 with material pot 7, pressure-type liquidometer 2, electromagnetic flowmeter 3 and pneumatic control valve 4 are arranged on pipeline 6 respectively successively, and pressure-type liquidometer 2, electromagnetic flowmeter 3 are connected with PLC 5 respectively with pneumatic control valve 4.
Flow control and supervisory system method: high position tank 1 is placed in a high position, material flow to material pot 7(or reactor certainly via pipeline 6), pressure-type liquidometer 2 and electromagnetic flowmeter 3 is utilized to monitor the flow of material in the liquid level in high position tank 1 and pipeline 6 respectively, above-mentioned Monitoring Data is transferred in PLC 5 respectively simultaneously, by pressure-type liquidometer 2 by after in high position tank 1, liquid level passes to PLC 5, PLC 5 is converted into volume automatically by work formula, after the time that operator will drip is input into computer, computer is converted into the dropping volume in the unit time automatically, then realize automatic uniform speed time by controlling the size of pneumatic control valve 4 to drip to reach reduce manually-operated error under the prerequisite of ensuring the quality of products, traffic conditions simultaneously in the real-time monitored pipeline 6 of electromagnetic flowmeter 3, operator monitor in real time altogether.
