Description
Technical field
It the utility model is related to a kind of test flotation column liquid level sensor.
Background technology
For flotation column, regulation and control to froth bed thickness are regulation and the key of control floatation indicators.
In practical application, typically combined using ball float, connecting rod and ultrasonic range finder etc., by speculating mineral syrup liquid in flotation column
Highly carry out Extrapolation froth bed thickness, but in test flotation column, (generally 50-200mm is not because cylinder diameter itself is small
Deng), cylinder space itself can be taken using ball float, be unfavorable for flotation froth by therefore typically being adopted in test flotation column
Detect liquid level with pressure sensor, still, in actual applications, due to ore pulp be one kind by liquid, solid, gas group
Into mixture, its density can change with the change of the factors such as pulp density, aeration quantity, and same pressure thus occurs
The different situation of actual height of lower liquid level, therefore current stress sensor actually can not truly reflect ore pulp in flotation column
The change of liquid level, the control follow-up to us bring problem.
In the test flotation column of existing measurement diameter very little, also someone detects liquid level using small-sized magnetic float liquidlevel meter
Highly, although so can accurately reflect very much liquid level, in use, the characteristics of due to ore pulp, ore pulp holds
The gap easily filled up between magnetic float and guide rod, causes magnetic float stuck, equally causes the failure of small-sized magnetic float liquidlevel meter, together
Sample is unfavorable for follow-up control.
Utility model content
The utility model overcomes existing for above-mentioned technology insufficient, there is provided it is a kind of it is rational in infrastructure, easy to use, in diameter very
Test flotation column level sensing is set to become a kind of precisely reliable test flotation column liquid level sensor in small test flotation column.
A kind of test flotation column liquid level sensor, including support tube, converter, magnetic are floating, guide rod and fly rod, the converter
Installed in the upper end of support tube, one end of the guide rod is arranged in support tube and is connected with converter, and the other end is from support
The lower end of pipe, which is stretched out, to be arranged on outside support tube, hollow, upper end open, lower end closed in the middle part of the fly rod, in the middle part of the magnetic float
It is more than the through hole of guide rod external diameter provided with diameter, the magnetic float is arranged in support tube and is sleeved on the outside of guide rod, described floating
Rod set is on the outside of guide rod, and the upper end of the fly rod is arranged in support tube and is connected with magnetic float, and the branch is stretched out in lower end
Stay tube, fly rod and the magnetic float can move up and down along guide rod, and the length of the fly rod causes the lower end of the guide rod to set all the time
Put in fly rod.Using upper structure, due to fly rod lower end closed, guide rod is arranged in fly rod all the time, and magnetic float is further through floating
Bar is promoted and slided on guide rod so that magnetic float is constantly on the liquid level of ore pulp at work, and magnetic float is not directly contacted with
Ore pulp, avoid the gap between magnetic float and guide rod fill up ore pulp and magnetic float is stuck phenomenon, ensure the accurate of level sensing
Reliably.
Preferably, the lower end of the guide rod is fixed with smooth in appearance, diameter is less than the bead of fly rod internal diameter.In favor of
Fly rod slides up and down on the outside of guide rod.
Preferably, lower end is provided with the mounting bracket for being easily installed in test flotation column top on the outside of the support tube.
Preferably, the opening of the support tube lower end and the size of fly rod match, and the upper end of the fly rod is floated close to magnetic
The position of son is provided with diameter and is more than fly rod diameter less than support bore, spacing for fly rod back-up ring.
Preferably, the length of the fly rod is more than the length of support tube.
In summary, the utility model is simple in construction, economical and effectively solve small-sized magnetic float liquidlevel meter in ore pulp
In the problem of easily blocking, test flotation column level sensing is become precisely reliable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, 1. support tubes, 2. mounting brackets, 3. fly rods, 4. transmitters, 5. magnetic floats, 6. guide rods, 7. beads, 8. gears
Circle.
Embodiment
In conjunction with accompanying drawing, technology contents of the present utility model are described further.
As shown in figure 1, a kind of test flotation column liquid level sensor, including transmitter 4, magnetic float 5, (these three portions of guide rod 6
Part is the original paper of magnetic float liquidlevel meter, and guide rod is a stainless steel tube, is connected to below transmitter, and the inside is to use tongue tube and resistance
The strip circuit board combined, the principle of magnetic float liquidlevel meter belong to magnetic couplings, and float is driven when liquid level rises
Rising, tongue tube forms closed-loop path because the magnetic of magnetic float makes reed switch conduction, with transmitter, then through internal conversion circuit
Final output 4--20mA signal).
The lower end of magnetic float 5 is connected to the light pipe of a lower end closed as fly rod 3, and the upper end of fly rod 3 is provided with a gear
Circle 8, one smooth ball 7 is installed in the bottom of conduit 6, in favor of the slip of fly rod 3.Transmitter 4 is arranged on support tube 1
End, the lower end of support tube 1 are arranged on mounting bracket 2, and mounting bracket 2 is placed in test flotation column top, and is higher than foam overflow face.Fly rod
3 length is suitable with guide rod 6, but longer than support tube 1, and length is depending on measurement liquid level change needs.
When test flotation column is not used, i.e., when there is no ore pulp in cylinder, fly rod 3 together with magnetic float 5 under gravity
Hung over by the back-up ring 8 of fly rod 3 in support tube 1, when liquid level rises and after submerge 3 lower end certain length of fly rod in test flotation column
(when i.e. buoyancy is equal to fly rod 3 and magnetic 5 gross weight of float), hereafter fly rod 3 can together with magnetic float 5 with mineral syrup liquid change and on
Rise or decline, so as to change resistance in guide rod 6, and corresponding current signal is exported by transmitter 4 and internal circuit, completed to examination
Test the detection of flotation column liquid level.So as to drive magnetic float to act by fly rod 3, allow fly rod 3 to substitute magnetic float 5 and connect with mineral syrup liquid
Touch, magnetic float 5 is constantly at work on the liquid level of ore pulp, so it is avoided that the phenomenon being stuck in magnetic float 5, is protected
Demonstrate,prove the reliability of the work of magnetic float 5.
Preferred embodiment of the present utility model is the foregoing is only, does not limit the utility model in any way,
For those skilled in the art, the utility model can have various modifications and variations.It is all in spirit of the present utility model
Within principle, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
