Abstract
The utility model relates to a high-temperature float type liquid-level automatic controller for the automatic control in the fabrication of liquid preparation. The high-temperature float type liquid-level automatic controller is composed of a sensing device, a controlling device, an electromagnetic valve and a drain pump. The high-temperature float type liquid-level automatic controller can control the opening and the closing of three switches through the motion of a floater connecting rod, and at the same time, the high-temperature float type liquid-level automatic controller can control the water drainage and feeding and can alarm. The high-temperature float type liquid-level automatic controller has the advantages of labor-saving, anti-liquid spillover, simple structure, convenient installation and wide range of application, so the high-temperature float type liquid-level automatic controller is suitable for rebuilding the existing equipment.
Description
The utility model relates to a kind of automaton.
Utilize thin film evaporator to circulate when concentrating in liquid preparation prepares, the height of liquid level is grasped by manual observation and by the control centrifugal pump in the liquid reservoir.This not only will take manpower, and just in case also can cause liquid to overflow waste accidentally, influences the quality of the pharmaceutical preparations.In the prior art, the device that high-rise water tower liquid level control is adopted comprises liquid level sensing device and circuit control device, and the just intake pump of its circuit control does not apply control to drainage procedure.
The utility model be just for controlling liquid level position in the liquid reservoir as required automatically when liquid preparation prepares, overcome the above-mentioned shortcoming in the conventional formulation technology and a kind of automaton of designing.
High temperature floatation type liquid level lifting self-actuated controller is made up of liquid level sensing device (comprising an airtight hollow float ［ 1 ］ that usefulness is high temperature resistant, resistant material is made and a float connecting rod ［ 2 ］), control device ［ 3 ］, solenoid valve ［ 4 ］ and unwatering pump ［ 5 ］.Control device is controlled unwatering pump and electromagnetic water inlet valve door simultaneously.
Accompanying drawing one is an embodiment.Float ［ 1 ］, float connecting rod ［ 2 ］ are made by plastics, and the float connecting rod is " ┐ " shape, and it vertically partly can make length-adjustable mantle fiber connection, to adapt to the needs of the maximum lifting limited fields of different receiver liquid levels.Float connecting rod one end has an awl rod base ［ 6 ］, the awl bar ［ 7 ］ that has three open-close on-off to use on this awl rod base, and the position of three switches ［ 22 ］ of installing with the box body upper wall is distinguished corresponding.Wherein ［ 7-a ］ is that alarm switch is bored bar for minimum level gauge tap awl bar, ［ 7-b ］ for high liquid level (HLL) gauge tap awl bar, ［ 7-c ］.Suitable position by awl rod base one end in the middle of the float connecting rod has stationary shaft perforation ［ 8 ］, in order to the float connecting rod is fixed on the connecting rod stationary shaft ［ 9 ］, the control device shell is a square box body ［ 10 ］, fixing feet ［ 11 ］ is arranged at the bottom, can borrow fixed screw ［ 12 ］ that controller is fixed on liquid reservoir ［ 13 ］ sidewall.Box body one side has stringer groove ［ 14 ］, and the centre is a float connecting rod stationary shaft ［ 9 ］.Another sidewall is control panel ［ 15 ］, relay indicating light ［ 16 ］, alarm lamp ［ 17 ］, disconnecting link switch ［ 18 ］, alarm bell ［ 19 ］ are arranged on it, start snapper ［ 20 ］, outage snapper ［ 21 ］, the box body upper wall is equipped with three switches ［ 22 ］, wherein ［ 22-a ］ to be minimum level gauge tap, ［ 22-b ］ be alarm switch for high liquid level (HLL) gauge tap, ［ 22-c ］.Switch pedestal ［ 23 ］ is that spiral is adjustable, and the top is contact spring sheet ［ 24 ］, and when the awl rod base moved up and down with the float connecting rod, three awl bars can insert or withdraw from three switches respectively to control its disconnection or connection.The screw of rotary switch base can be adjusted the height of switch spring sheet.Thereby regulate the critical point of control liquid level.Relay contactor ［ 25 ］ is housed on box body one sidewall.Solenoid valve is installed on the fluid injection pipeline ［ 26 ］, is connected with controller through lead.Manually-operated gate ［ 27 ］ is arranged on the fluid injection pipeline in addition.
Control circuit figure sees accompanying drawing two for details.Wherein K1 is disconnecting link switch ［ 18 ］, K2 is high liquid level (HLL) gauge tap ［ 22-a ］, K3 is minimum level gauge tap ［ 22-b ］, K4 is alarm switch ［ 22-c ］, TQ is starting switch snapper ［ 20 ］, AQ is cut-off switch snapper ［ 21 ］, and K2, K4, TQ are normal open switch, and K3, AQ are normally closed switch.

In the course of work, will start snapper TQ and connect, draining pump is started working, and drops to minimum critical point such as liquid level, and the cone rod base rises minimum level gauge tap cone bar ［ 7-a ］ is put out K switch 3, circuit breaker, and draining pump quits work, and liquid level gos up. When liquid level rose to the highest critical point, the cone rod base descended and makes high liquid level (HLL) gauge tap cone bar ［ 7-b ］ with K switch 2 closures, and circuit is connected, and draining pump work descends liquid level. Hold such as liquid level When continuous rising reached the warning critical point, the cone rod base further descended and makes alarm switch cone bar ［ 7-c ］ with K switch 3 closures, and alarm bell is rung, and alarm lamp is bright, and the closed electromagnetic valve on the liquid injecting pipeline waits for that messenger adjusts or repairs. Only need pressing AQ this moment, and warning system opens circuit. It is complete to adjust repairing, connects TQ again, can re-start the above-mentioned course of work.
The utlity model has characteristics simple in structure, easy for installation. Because it is adjustable that float connecting rod and switch pedestal are, therefore widely applicable, especially be fit to amateur production unit to the transformation of existing equipment. Can play the saving manpower, prevent the effect of overflow waste.
