The drum is driven by the motor through a decelerator, and the other end of a drum shaft is connected with a screw rod. A screw nut is arranged on the screw rod. One side of the screw nut is connected with a thread winding wheel, and the other side is connected with a sliding contact of a sliding resistor which is connected with a liquid-level gauge. The utility model can automatically measure liquid level position in timing, and is accurate in measuring and reliable in operation.
Description
The utility model is a kind of surveying instrument of measuring liquid level position, is particularly useful for measurement and can produces a large amount of gases and be mixed with solid material, the easy liquid level position that scabs and need constantly to stir that forms.
Existing liquid level gauge mainly contains following several, floating-type: simple in structure but can not use in liquid that stirs and the liquid that easily scabs.Pressure type: be contained in liquid bath bottom, not the liquid and the unfixed liquid of proportion that easily scab of energy measurement.Ultrasonic type: do not contact liquid level, measure more accurately, produce a large amount of aerosols and the surface produces on the liquid of more foam but can not be used in.Many production runes are comparatively complicated, easily scab as the liquid in the reactive tank in the aluminum oxide production process, and the temperature height, vapour density is big, and liquid constantly stirs, and produces more foam, and proportion constantly changes, but needs continuous measuring liquid level.
The purpose of this utility model is exactly at the specific condition in the aluminum oxide production process, designs a kind of liquid level gauge that can measure and show the liquid level height automatically, also can be used on the environment of other similar working condition.
The utility model is to realize like this, it is made up of probe, wire rope, roller and motor and control circuit etc., probe is made with hollow metal sphere, connects with wire rope above to be hung in the liquid bath, and wire rope is by the supporting of the fixed pulley above the liquid bath and turn to the back on roller; Roller by motor through the speed reduction unit driven rotary, the roller axle other end is connected with a leading screw, being equipped with one on the leading screw is driven along the axially movable screw of leading screw by leading screw, screw one side is connected with and can makes the glass pulley of wire rope dead cast on roller, and opposite side connects the slider of a linear slide resistance; A straining pulley that is connected lever one end is housed between wire rope glass pulley and the fixed pulley, and straining pulley is equipped with the straining pulley limiting plate by a side that does not have wire rope.The lever other end is equipped with a magnetic conduction sheet that is inserted in the magnetic switch, under the magnetic conduction sheet spring is housed, magnetic switch connects control circuit, and control circuit comprises step-down rectifying circuit, motor commutation control circuit, regularly metering circuit, the limit are controlled warning circuit and liquid level display circuit.Swept resistance connects a content gauge, and the limit switch of adjustable position is equipped with at the leading screw two ends respectively.Regularly metering circuit regularly descends probe and measures liquid level position, and when probe touches liquid level, the buoyancy of generation reduces steel wire rope tension, and straining pulley moves trigger control circuit makes motor backward rotation probe leave liquid level; Roller drives leading screw and rotates, and makes screw generation rectilinear motion and converts the liquid level indicator signal to.
But the utility model timing automatic is measured liquid level position, is applicable to various complex operating environment, also can be used as to measure some solid material level, measures accurately reliable operation.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is electrical schematic diagrams of the utility model electrical control part.
The utility model is made up of probe (8), wire rope (7), roller (17) and motor (19) and control circuit etc., probe (8) is made with hollow metal sphere, be hung in the liquid bath (9) with wire rope (7) connection above, wire rope (7) supports and turns to the back on roller (17) by the fixed pulley above the liquid bath (6); Roller (17) by motor (19) through speed reduction unit (18) driven rotary, the roller axle other end is connected with a leading screw (11), being equipped with one on the leading screw (11) is driven along the axially movable screw of leading screw (20) by leading screw (11), screw (20) one sides are connected with and can make the glass pulley (10) of wire rope (7) dead cast on roller (17), and opposite side connects the slider (12) of a linear slide resistance (13); A straining pulley (5) that is connected lever (4) one ends is housed between wire rope glass pulley (10) and the fixed pulley (6), and straining pulley (5) is equipped with the straining pulley limiting plate by a side that does not have wire rope.Lever (4) other end is equipped with a magnetic conduction sheet (1) that is inserted in the magnetic switch (2), spring (3) is housed under the magnetic conduction sheet (1), magnetic switch (2) connects control circuit, and control circuit comprises step-down rectifying circuit, motor commutation control circuit, regularly metering circuit, the limit are controlled warning circuit and liquid level display circuit.Swept resistance (13) connects a content gauge (16), and limit switch (14), (15) of adjustable position are equipped with at leading screw (11) two ends respectively.Energized, motor (19) begin counter-rotating, and probe (8) descends and measures, and when popping one's head in (8) when contacting liquid level, steel wire (7) tension force reduces, and magnetic conduction sheet under the pulling force of spring (3) (1) moves down with lever (4) left end, and K is connected, the energising of T2 pipe base stage.The contact closure of J22 makes the T1 pipe because of base stage the electricity conducting be arranged, the J1 energising, and motor (19) stops counter-rotating.The contact closure of J2 is just changeed motor (19).Probe (8) rises and leaves liquid level, and lever (4) right-hand member is pressed in again on the stop, and magnetic conduction sheet (1) disconnects K again with moving on the lever.After K disconnected, the base current of T2 pipe was supplied with by C5, kept the conducting of T2 pipe.The length (promptly probe leaves the height of liquid level) of T2 pipe ON time is regulated with R2.When the C5 discharge off, when the T2 pipe ends, J22, J2 outage, motor (19) stall.After the contact of J22 disconnected, the substrate current of T1 pipe was supplied with by C2, kept the T1 pipe and continued conducting.Be the time-delay stage this moment, and the length of delay time is determined by the amount of capacity of C2 and the resistance of R1.When time-delay finished, the T1 pipe ended, the J1 outage, and motor (19) reverses again, and probe (8) descends again, carries out one-shot measurement again.After this just carry out periodic measurement automatically.When popping one's head in (8) when being raised to the extreme higher position, KG connects, the J3 energising, and the contact of J3 disconnects, and J22, J2 can not be switched on, and motor (19) can not just change, and probe (8) no longer rises, and sends the full level alarm signal simultaneously.When popping one's head in (8) when dropping to extreme lower position, KD connects, and makes the T1 pipe collector receive power cathode through D, and J1 can not cut off the power supply, and motor (19) can not reverse, and probe (8) no longer descends, and sends the low alarm signal simultaneously.
