Abstract
Provided is a hydraulic oil level alarming device for a filter press. The device is provided with a floating ball type liquid level switch arranged above a hydraulic oil tank body of the filter press, a switch base is arranged on the oil tank body, the switch base is connected with the floating ball type liquid level and is arranged on the oil tank body, the hydraulic oil level alarming device is provided with a power switch connected with a PLC, the floating ball type liquid level switch is connected with the PLC connected with an indicator lamp, the indicator lamp is in parallel connection with a buzzing alarm, the floating ball type liquid level switch is arranged above the hydraulic oil tank body of the filter press and is connected with the PLC, a contact of the floating ball type liquid level switch can enable the PLC to send out an instruction so that the indicator lamp can flash and the buzzing alarm can give out sound to remind operation personnel of the insufficient oil level of the oil tank body and remind the operation personnel to fill the oil tank body with oil in time, wherein the indicator lamp and the buzzing alarm are in parallel connection, and therefore a filter hydraulic system of the filter press can be normally operated.
Description
Technical field
The utility model relates to a kind of pressure filter hydraulic pressure warning device.In more detail, relate to a kind of pressure filter hydraulic pressure level alarming device.
Background technology
Pressure filter is the main filter plant of Separation of Solid and Liquid industry, hydraulic system is the chief component of pressure filter, the actuating medium of hydraulic system is hydraulic oil, hydraulic oil reservoir exists in oil box, the hydraulic pressure oil level is arranged on the position that meets circulation in oil box, hydraulic oil enters the cylinder body assembly by oil pump and operation valve, realize that piston rod back and forth moves, material filtering compresses filter plate by the operation of cylinder body assembly piston rod, make filter plate form the sealed chamber of filtering, feeder pump injects filter chamber to material and forms filter cake, hydraulic system is actuated mechanical mechanism and is realized pulling open filter plate removal filter cake, reach the purpose of Separation of Solid and Liquid.
But find that hydraulic system has weak point in using at the scene, contain chemical gas due to what the material that the pressure filter working environment is moist and filter had, make the parts of hydraulic system be easy to be corroded, cause the parts damages of hydraulic system in long-term the use, hydraulic oil easily consumes and reveals in circulation and maintenance process, make the hydraulic oil potential drop in oil box low, oil level does not reach the demand of cylinder body assembly circulation, make the filter pad chamber can not press seal, cause material filtering to leak material, operating personnel can not find again in time, while causing Hydraulic System of Extract Coal Filter Press for the shortage of oil material filtering, can not normally move.
The utility model content
The purpose of this utility model is the weak point existed in the above-mentioned background technology in order to solve, and pressure filter hydraulic pressure level alarming device is provided.
To achieve these goals, the utility model provides pressure filter hydraulic pressure level alarming device, level switch is set, and this level switch is float-ball type, is arranged on above pressure filter hydraulic oil casing, switch pedestal is installed above oil box, switch pedestal connects float type level switch and is arranged on above oil box, is provided with power switch and connects the PLC controller, and float type level switch connects the PLC controller, the PLC controller connects pilot lamp, pilot lamp buzzer siren in parallel.
Above described oil box, switch pedestal is installed, switch pedestal is arranged on above oil box with bolt.
Above described oil box, switch pedestal is installed, the material of making the switch pedestal use is stainless steel.
Implemented to have the beneficial effect of the low automatic alarm of hydraulic pressure oil level by the utility model, pressure filter hydraulic oil casing is installed float type level switch and is connected the PLC controller, the contact of float type level switch can make the PLC controller send instruction, make pilot lamp flicker and buzzer siren in parallel send sound, remind operating personnel's oil box oil level deficiency to refuel in oil box in time, perhaps hydraulic oil has been filled it up with and has been stopped refueling, and while making the pressure filter material filtering, hydraulic system is normally moved.
The accompanying drawing explanation
Following drawings and Examples further illustrate the utility model.
Fig. 1 is pressure filter hydraulic pressure level alarming device schematic diagram of the present utility model.
1. oil box in figure, 2. switch pedestal, 3. float type level switch, 4.PLC controller, 5. power switch, 6. buzzer siren, 7. pilot lamp.
Embodiment
Refer to shown in Fig. 1, the pressure filter hydraulic pressure level alarming device that the utility model provides, float type level switch 3 connecting valve bases 2 are set to be arranged on above oil box 1, switch pedestal 2 is used bolt to be arranged on above oil box 1, the material that switch pedestal 2 is used is stainless steel or structural carbon steel, through the machine-shaping of C6140 type lathe, be provided with power switch 5 and connect PLC controller 4, the contact of float type level switch 3 is connected with PLC controller 4, and PLC controller 4 is connected with pilot lamp 7 buzzer siren 6 in parallel.
Select float type level switch 3 to be arranged on above oil box 1, because hydraulic oil is that liquid has buoyancy, ball float is according to the supporting making of the buoyancy of liquid, when liquid level goes up, ball float is corresponding rise also, when should liquid level descending, ball float is corresponding decline also, when going up or dropping to the position of setting, ball float can be encountered the travel switch of setting, thereby make travel switch send electric signal, control panel is received signal action at once and is switched on power, PLC controller 4 is received signal and is sent instruction simultaneously, make pilot lamp 7 flickers and buzzer siren 6 send sound, remind operating personnel's oil box oil level deficiency in time to the interior oiling of oil box 1, perhaps hydraulic oil has been filled it up with and has been stopped refueling, while making the pressure filter material filtering, hydraulic system is normally moved.
Claims (3)
