Description

Float bowl-type ultrasonic wave flotation device level sensor
Technical field
The utility model belongs to the technique of preparing apparatus field, particularly a kind of float bowl-type ultrasonic wave flotation device level sensor.
Background technology
In selecting the machine running, liquid level in the necessary accurately monitoring machine is to guarantee the normal operation of flotation device.To be used to monitor the flotation device level sensor at present have ultrasonic type, and radar type is also arranged.Owing in flotation device, there are a large amount of foams, and froth bed is constantly changing, can't accurately detect the height of ore pulp, liquid level gauges such as the electric node formula that adopts, float-ball type, throw-in type all can't meet the demands at present, this is because flotation pulp contains and adheres to stickum in a large number, and conduction, when electric node adhered to conductive materials, electric node makes long-term conducting measured failure.Can hang many viscous mass on the bar of float-ball type liquid level gauge, ball float can't normally be moved up and down.Called putting-into-type liquid level meter has air-vent to be easy to be stopped up by stickum, in case stop up, just can't accurately measure liquid level.
Summary of the invention
The purpose of this utility model provides a kind of float bowl-type ultrasonic wave flotation device level sensor, can prevent from effectively to hang with the influence of viscous mass to level detection on the liquid level foam of ore pulp and the bar, thereby directly measure the flotation device liquid level exactly.
The purpose of this utility model realizes by following technical proposals.
According to float bowl-type ultrasonic wave flotation device level sensor of the present utility model, it is characterized in that by drum shape shell, be contained in the supersonic detector in this drum shape shell, cross-under, that have the detection keg float of limiting block and ultrasonic reflections dish and the be located at the shell outside mutually installing rack of following mounting disc with in the shell that is located at this supersonic detector below is formed.
Described supersonic detector is by the ultrasonic probe that is located in the drum shape shell, with the last mounting disc that this probe is connected with shell, is connected the signal connector on this ultrasonic probe, and signal connector is connected and the cable that passes shell is formed therewith.
Described cable passes the shell position and is provided with seal, and described probe is connected with last mounting disc by hold-down nut.
Described detection keg float is by the sample bucket at the no end that fuses with outer casing underpart, be located at the bicone cylinder keg float in this sample bucket, be connected on the cylindrical keg float axis of this bicone and pass down the connecting rod of mounting disc, the limiting block that is located at the ultrasonic reflections dish of this connecting rod upper end and is located at mounting disc downside under being positioned on the connecting rod is formed.
Described sample bucket is that hollow out does not have end bucket.
Connecting rod in the described bicone cylinder keg float is provided with counterweight.
When adopting the utility model, level sensor is fixed on the flotation device sidewall by installing rack, will not have end outer casing bottom and is placed in the fluid to be measured, and keg float is immersed in the fluid to be measured.Because the weight of keg float itself just can not be floated keg float foam fully, but fluctuates with fluid to be measured.The limiting block and the ultrasonic reflections dish that detect in the keg float define the distance that keg float moves up and down, ultrasonic probe sends ultrasonic wave and arrives the ultrasonic reflections dish, detect the change in location of reflecting disc, convert the signal of telecommunication to, be connected on secondary meter or the computer by cable, realize automatic demonstration the flotation device liquid level.
Benefit of the present utility model is:
1, the bottom of drum shape shell hollow out is immersed in the fluid to be measured, and fluid to be measured and keg float are isolated, and can reduce liquid fluctuating, reducing the foam viscous mass influences liquid level, more accurate detection liquid level, and accuracy is 3/1000ths, and can import the 0-20mA signal, have versatility.
2, the utility model adopts bicone cylinder keg float, has solved the resistance of foam viscous mass.
3, in the bicone keg float, be provided with counterweight, increased keg float weight, bicone cylinder keg float is immersed in the ore pulp, can overcome foam buoyancy, accurately measure the ore pulp height.
4, shell and ultrasonic detector adopt the design of anti-water seal, have solved the problem of liquid evaporation water steam, have prolonged the service life of detector.
5, adopt the ultrasonic wave non-contact measurement, overcome corrosion and be stained with problems such as stagnant.
6, the utility model is rational in infrastructure, and simple installation is durable, and corrosion resistance is strong.Keg float adopts stainless steel to make, and can realize that the flotation device liquid level controls automatically, remedies the blank of flotation device equipment, has very high promotional value.
