Abstract
The utility model discloses a float-type liquid level detection device which comprises a support and an aspirating pump. Pulleys are respectively arranged on both sides of the support, floats are respectively hung at both ends of a steel wire rope bypassing from the two pulleys, a contact part is fixedly connected at the middle part of the steel wire rope, travel switches are respectively arranged on both sides of the support, and the contact part is positioned between the two travel switches which are connected with the aspirating pump through a wire. The utility model with simple structure and reliable action can effectively detect the position of the liquid level, and is not only free from the influence of the liquid cleanliness and the bad factors of the operating environment but also convenient to use.
Description
Technical field
The utility model relates to a kind of liquid level detection device, particularly the float-type liquid level detection device.
Background technology
At present, the wash-down water of steelworks Ventilator Room draught fan impeller is generally all concentrated and is pooled to behind the Ventilator Room in the back pool, is extracted into sewage disposal system by two water pumps then and handles, thereby reach recycling purpose.Messy through the water quality after the draught fan impeller flushing, impurity is very many, water temperature is about 200C, and surface water of pools steam is very big during winter, so brought very big difficulty for the Level Detection in this pond, called putting-into-type liquid level meter was used at the scene, because the too dirty liquid level gauge probe that causes of water quality stops up, must regularly clean, otherwise, cisco unity malfunction, maintenance increases.Also used ultrasonic level gage, and caused detection inaccurate because surface, pond in winter steam is big, so conventional detection means all can not satisfy on-the-spot demand.
The utility model content
The purpose of this utility model is to provide a kind of float-type liquid level detection device, and it is simple in structure, the not influence of liquid body cleanliness factor and working environment undesirable element, and reliable in action, easy to use.
The purpose of this utility model is achieved in that a kind of float-type liquid level detection device, comprise support and suction pump, the both sides of support are being provided with a pulley respectively, a floating drum is being hung at wire rope two ends of walking around from two pulleys respectively, the middle part of wire rope affixed one the touching part, in the both sides of support a travel switch is being set respectively, the touching part is between two travel switches, and travel switch links to each other by lead with suction pump.
When the utility model uses, support is installed in the top, pond, by floating drum perception water surface liquid level height, when water surface liquid level was high, floating drum rose, and along with the touching part contacts with travel switch, suction pump is started working and drawn water.After water surface liquid level descended, floating drum descended thereupon, and the counter motion of touching part and another travel switch are to contacting, and suction pump quits work.So repeatedly, can prevent effectively that water in the pond from overflowing and drain phenomenon.The original mode accuracy rate of certain steelworks Ventilator Room back pool Level Detection is 83%, to such an extent as to liquid level signal is inaccurate to cause directly in the pond that water level is too high to be full of the pond and spilling water or water pool inner water are drained by water pump, cause more equipment failure, liquid level detection device maintenance before is big, needs regularly to clean probe.The Level Detection accuracy rate has been brought up to more than 98% after adopting the utility model, has increased substantially this reliability of system operation, has reduced the maintenance of safeguarding the worker significantly simultaneously, and near non-maintaining state, the indirect benefit that is produced is bigger.The utility model is simple in structure, be fit to be applied in the more abominable pond liquid level detection of environment, the immalleable occasion of the detection means that particularly water quality is dirtier, water vapour is bigger or conventional, can effectively detect the liquid level position, the not influence of liquid body cleanliness factor and working environment undesirable element, reliable in action, easy to use.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
A kind of float-type liquid level detection device, as shown in drawings, comprise support 8 and suction pump 11, the both sides of support 8 are being provided with a pulley 7 respectively, a floating drum 1 is being hung at wire rope 4 two ends of walking around from two pulleys 7 respectively, the middle part of wire rope 4 affixed one the touching part 6, said touching part 6 is iron plate or plastic plate.In the both sides of support 8 travel switch 5 is being set respectively, touching part 6 is between two travel switches 5, and travel switch 5 and suction pump 11 link to each other by lead.
Be aggregated into back pool inlet channel 10 from six typhoon machine impeller wash-down waters by pipeline, flow into thus in the back pool 2, this pond liquid level is provided with upper limit and lower limit, when liquid level arrives upper limit, floating drum 1 rises, automatically start water pump 11, water is extracted into the effluent cycle system, when liquid level arrives low when spacing, water pump 11 quits work, wait for retaining, so repetitive process guarantees that water level in water pool is in the scope of setting.
Claims (2)
