Abstract
The utility model relates to a non-contact type liquid level detector. The non-contact type liquid level detector is characterized by comprising a buoyancy device guide groove (1), a buoyancy device (2), a first fixed pulley (3), a second fixed pulley (4), a thin connecting line (5), a contact-type liquid level meter (6), a magnetic bar (7), a magnetic latching switch (8) and a counterweight (9), wherein the buoyancy device guide groove (1) is perpendicularly fixed in an emulsion tank, the buoyancy device (2) is connected with the magnetic bar (7) through the thin connecting line (5) which passes through the first fixed pulley (3) and the second fixed pulley (4), the magnetic bar (7) is arranged in the contact-type liquid level meter (6), the magnetic latching switch (8) is arranged on the contact-type liquid level meter (6), and the counterweight (9) is arranged at the lower end of the magnetic bar (7). Compared with the prior art, the communicating pipes at the upper and the lower ends of the contact-type liquid level meter are removed and the magnetic bar is out of contact with the emulsion, so as to prevent blocking due to oily substances and iron powders which are adsorbed on the magnetic bar. The non-contact type liquid level detector is particularly suitable for detecting the level of viscous liquid.
Description
Technical field
The utility model belongs to the steel rolling equipment technical field, specifically the major equipment member of emulsion Level Detection.
Background technology
Existing liquid level detection device is the contact liquid level gauge, the top and bottom of contact liquid level gauge have conduit to be communicated with emulsion box respectively, effect according to law of connected vessels lower end conduit makes the liquid level in the contact liquid level gauge the same with liquid level in the emulsion box high, the lifting along with the lifting of liquid level of one magnetism stick is arranged in the contact liquid level gauge, there are four magnetic maintained switchs the liquid level gauge outside, when bar magnet arrives magnetic maintained switch position, the signal condition of magnetic maintained switch changes, and is used to indicate corresponding liquid level.But emulsion contains a large amount of oily matters and iron powder in the practical application, behind bar magnet absorption oily matter and the iron powder in liquid level gauge jam, can not normal lifting, thereby can not normally detect liquid level along with the lifting of liquid level.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of contactless Level meter.Technical solutions of the utility model are as follows: this contactless Level meter is made up of buoyant device gathering sill, buoyant device, first fixed pulley, second fixed pulley, thin connecting line, contact liquid level gauge, bar magnet, magnetic maintained switch and counterweight counterweight.The buoyant device gathering sill is vertically fixed in the emulsion box, buoyant device is connected with bar magnet through first fixed pulley and first fixed pulley by thin connecting line, bar magnet is arranged in the contact liquid level gauge, and the contact liquid level gauge is provided with the magnetic maintained switch, and the lower end of bar magnet is provided with the counterweight counterweight.Buoyant device lifting with the lifting of emulsion liquid level, drive the bar magnet lifting by thin connecting line and first fixed pulley and first fixed pulley during buoyant device lifting, when bar magnet was elevated to magnetic maintained switch place, corresponding magnetic maintained switch signal condition changed with the start-stop of control emulsion pump.
The utility model compared with prior art because the connecting tube of contact liquid level gauge cancellation top and bottom, bar magnet can not contact emulsion, thereby has avoided bar magnet absorption oily matter and iron powder the situation of jam to occur.Be particularly suitable for viscous liquid and detect the liquid level use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, the buoyant device gathering sill, 2, buoyant device, 3, first fixed pulley, 4, second fixed pulley, 5, thin connecting line, 6, the contact liquid level gauge, 7, bar magnet, 8, the magnetic maintained switch, 9, the counterweight counterweight.
Embodiment
Below in conjunction with Figure of description and embodiment the utility model is described further.
This contactless Level meter is made up of buoyant device gathering sill 1, buoyant device 2, first fixed pulley 3, second fixed pulley 4, thin connecting line 5, contact liquid level gauge 6, bar magnet 7, magnetic maintained switch 8 and counterweight counterweight 9.Buoyant device gathering sill 1 is vertically fixed in the emulsion box, buoyant device 2 is connected with bar magnet 7 through first fixed pulley 3 and second fixed pulley 4 by thin connecting line 5, bar magnet 7 is arranged in the contact liquid level gauge 6, and contact liquid level gauge 6 is provided with magnetic maintained switch 8, and the lower end of bar magnet 7 is provided with counterweight counterweight 9.Buoyant device 2 lifting with the lifting of emulsion liquid level, drive bar magnets 7 liftings by thin connecting line 5 and first fixed pulley 3 and second fixed pulley 4 during buoyant device 2 liftings, when bar magnet 7 was elevated to magnetic maintained switch 8 places, corresponding magnetic maintained switch 8 signal conditions changed with the start-stop of control emulsion pump.Make bar magnet 7 lifting with the lifting of buoyant device 2, must carry out counterweight with 9 pairs of buoyant devices 2 of counterweight counterweight and bar magnet 7, both the weight of buoyant device 2 equaled the weight sum of the emulsion that the weight of the weight of bar magnet 7 and counterweight counterweight 9 and buoyant device 2 discharge when floating.
Claims (2)
1. contactless Level meter, it is characterized in that this Level meter is by buoyant device gathering sill (1), buoyant device (2), first fixed pulley (3), second fixed pulley (4), thin connecting line (5), contact liquid level gauge (6), bar magnet (7), magnetic maintained switch (8) and counterweight counterweight (9) are formed, buoyant device gathering sill (1) is vertically fixed in the emulsion box, buoyant device (2) is connected with bar magnet (7) through first fixed pulley (3) and second fixed pulley (4) by thin connecting line (5), bar magnet (7) is arranged in the contact liquid level gauge (6), contact liquid level gauge (6) is provided with magnetic maintained switch (8), and the lower end of bar magnet (7) is provided with counterweight counterweight (9).
