Abstract
The utility model discloses a liquid level detection apparatus for liquid corrosion, including a detection rod (4) and a ball float (5), the detection rod (4) is fixed on the ball float (5), an inducting ring (3) is sleeved on the detection rod (4), a fixing support (1) is sleeved on the detection rod (4), the fixing support (1) fixes the detection rod (4) to the ball float (5), the ball float (5) is floated on the tank liquid in a plating tank body (6), the side surface of the fixing support (1) is provided with a proximity switch (2), and the two wires of the proximity switch (2) are respectively connected to the input points of +24 and plc of a direct current 24v power supply. The liquid level detection apparatus can timely control and start a jury pump by means of ball float liquid level, and effectively solves and prevents the phenomenon that the upper tank has no liquid level caused by the damaged pump impellers or the coming-off pump shaft, thereby ensuring the production line always to be in a better state.
Description
Technical field
The utility model relates to a kind of liquid level detection device of corrosive liquid.
Background technology
The manufacturing industry of the multinomial operations such as that the production of steel cord relates to is rough, thermal treatment, plating.As the plating of key equipment, effect aborning is very important.The little by little fluctuation of electroplating all can cause huge loss.The pumps such as existing electroplating degreasing groove, water-quenching, salt pickling, zinc sulfate and phosphatization all are to adopt the using and the reserved, utilize motor linkage.When a pump motor damages, can automatically enable the another pump, guarantee to produce normally, but this structure has following shortcoming: 1, water-quenching temperature is high, and the pump leaf is often aging; 2, hydrochloric acid has corrosivity, and pump shaft often rots; 3, the easy crystallization of zinc sulfate often causes pump shaft stuck; 4, phosphoric acid has corrosivity, causes pump shaft to rot to come off.These all faults all may cause in batches underproof generation, cause steel wire to scrap.
Summary of the invention
The utility model provides a kind of liquid level detection device of corrosive liquid, it utilizes Floating Ball Liquid Level can in time control the startup stand-by pump, effectively solve and avoid the pump leaf to damage or pump shaft comes off the upper groove that causes without the liquid level phenomenon, make production line be in all the time good state.
The utility model has adopted following technical scheme: a kind of liquid level detection device of corrosive liquid, it comprises test bar and ball float, test bar is fixed on the ball float, at the test bar cover inductance loop is arranged, at the test bar cover fixed support is arranged, fixed support is fixed test bar and ball float, and ball float swims on the interior tank liquor of electroplating cell body, be provided with approach switch in support bracket fastened side, two lines of approach switch be connected to respectively direct current 24v power supply+24 and the plc input point on.
Described fixed support is set to ］ type.
The utlity model has following beneficial effect: test bar of the present utility model is fixed on the ball float, at the test bar cover inductance loop is arranged, at the test bar cover fixed support is arranged, fixed support is fixed test bar and ball float, ball float swims on the interior tank liquor of electroplating cell body, be provided with approach switch in support bracket fastened side, two lines of approach switch are connected to respectively on direct current 24v power supply+24 and the plc input point, it utilizes Floating Ball Liquid Level can in time control the startup stand-by pump, effectively solve and avoid the pump leaf to damage or pump shaft comes off the upper groove that causes without the liquid level phenomenon, make production line be in all the time good state.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
In Fig. 1, the utility model provides a kind of liquid level detection device of corrosive liquid, it comprises test bar 4 and ball float 5, test bar 4 is fixed on the ball float 5, at test bar 4 covers inductance loop 3 is arranged, at test bar 4 covers fixed support 1 is arranged, fixed support 1 is set to ］ type, fixed support 1 is fixing with ball float 5 with test bar 4, and ball float 5 swims on the tank liquor in the electroplating cell body 6, is provided with approach switch 2 in the side of fixed support 1, two lines of approach switch 2 are connected to respectively on direct current 24v power supply+24 and the plc input point, when single pump work liquid level was normal, direct current 24v electricity was inputted to plc by approach switch 2, when liquid level descends, when approach switch 2 is responded to less than inductance loop 3, approach switch 2 is without the input point that is input to plc, and the plc program behavior sends the instruction that makes stand-by pump work, makes the liquid level in the electroplating cell body 6 in the stand-by pump guarantee of work.
Claims (2)
1. the liquid level detection device of a corrosive liquid, it is characterized in that it comprises test bar (4) and ball float (5), test bar (4) is fixed on the ball float (5), at test bar (4) cover inductance loop (3) is arranged, at test bar (4) cover fixed support (1) is arranged, fixed support (1) is fixing with test bar (4) and ball float (5), ball float (5) swims on the interior tank liquor of electroplating cell body (6), be provided with approach switch (2) in the side of fixed support (1), two lines of approach switch (2) be connected to respectively direct current 24v power supply+24 and the plc input point on.
