Description
Technical field
The utility model belongs to Liquid level field, particularly a kind of liquid-level auto-control device.
Background technology
At present, in when carrying out industry and being raw, due to the consumption and evaporation etc. of other liquid such as reactant liquor or water in production run process, liquid is caused constantly to reduce, liquid level constantly declines, and when liquid level dropping liq reduces to a certain degree, can cause the temporary transient stopping of producing, thus cause the interruption of production line, great loss can be caused to production like this.In general, in order to ensure the normal of liquid level, need to pay close attention to liquid level in real time by production work personnel, when liquid level reaches below a certain scale mark by the time, adding liquid, thus the carrying out smoothly of the work of guarantee.
But, so, owing to needing special staff to monitor liquid level, waste manpower and materials, and due to the mode by artificial adding liquid, be difficult to the addition controlling liquid, namely can not reach accurate control to liquid level.
Therefore, needing now a kind of liquid-level auto-control device badly, automatically can monitor in real time liquid level, when reaching certain liquid level line, automatically carrying out liquid interpolation, when being added to required liquid level line, stopping liquid feeding.
Utility model content
The utility model proposes a kind of liquid-level auto-control device, solve in prior art and need special staff to monitor liquid level, waste manpower and materials, and due to the mode by artificial adding liquid, be difficult to the addition controlling liquid, namely can not reach the accurate problem controlled to liquid level.
The technical solution of the utility model is achieved in that the utility model comprises water storage device, also comprise liquid adding tube road and liquid level sensor, one end, described liquid adding tube road is stretched in water storage device, the other end is connected with adjustable speed water pump, water delivering orifice is provided with bottom described water storage device, described water delivering orifice is provided with switch valve, described liquid level sensor one end extend into water storage device until bottom water storage device, the other end stretches out water storage device to be observed at any time for staff, and described liquid level sensor and described adjustable speed water pump are connected with PLC.
As one preferred embodiment, described PLC is provided with human-computer interaction interface, and staff can realize controlling by human-computer interaction interface.
As one preferred embodiment, described PLC establishes viridescent startup button and red closedown button, avoids maloperation occurs.
As one preferred embodiment, the minimum unit of display of described liquid level sensor is mm, and the precision controlling liquid level meets high requirement.
As one preferred embodiment, described water storage device is stainless steel water storage device, improves the serviceable life of water storage device.
As one preferred embodiment, described stainless steel water storage device inside surface also scribbles antirust coat, improves the serviceable life of water storage device further.
As one preferred embodiment, described liquid adding tube road is also provided with solenoid valve, adjustable speed water pump can be coordinated to control liquid and add.
As one preferred embodiment, described PLC is also connected with alarm, when liquid level reaches certain scale mark, reports to the police.
As one preferred embodiment, described alarm comprises pilot lamp and hummer, can be reported to the police by pilot lamp and hummer two kinds of modes to staff.
After have employed technique scheme, the beneficial effects of the utility model are: in industrial process, when the liquid level that liquid level sensor tests water storage device reaches below setting liquid level, alarm is reported to the police, PLC can control adjustable speed water pump and solenoid valve automatically, liquid interpolation is carried out to water storage device, when adding required liquid level to, PLC stops the liquid feeding in water storage device, namely extra work personnel control liquid level is not needed, staff is not needed to carry out liquid level interpolation yet, use manpower and material resources sparingly, and due to the precision of liquid level sensor higher, ensure that the interpolation of liquid level meets accuracy requirement.
