Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of Press-Filtering Machine Control System, particularly uses in production process of titanium pigment, to the improvement of U-shaped filter press.
Background technology
U-shaped filter press is the visual plant in the metatitanic acid Producing Titanium Dioxide processed, the filter press machinery structure of prior art is complicated, and owing to being under the acid working environment for a long time, the corrosion of filtering equipment main body parts is quite serious, and the press filtration cake moisture is up to more than 55%, and filter cloth replacing is frequent, do not met the production run requirement, can't realize automation control, safeguard to maintenance repair and brought many inconvenience, the recondition expense cost is high.Filter press mainly is comprised of body part and control section.The body part mainly is comprised of frame, filter mechanism, hold-down mechanism, arm-tie transmission mechanism and catch tray transmission mechanism.Control section is comprised of Hydraulic Station, power distribution cabinet etc.
U-shaped filter press of the prior art mainly contains the defective of two aspects, and the first, in service in the filter press squeezing, can pressure dwelling loop be vital, reach pressurize, has determined the final result who separates of diluted Ti solution.Adopt the pressurize of single-circuit hydraulic control one-way valve control loop in the U-shaped filter press main fuel tank of prior art, filter press requires feed pump to provide pressure to be not less than 0.6Mpa, and master cylinder provides pressure to be not less than 12MPa.In the long-play, after hydraulic control one-way valve in the oil circuit damaged, master cylinder also just can't play the pressurize effect, has a strong impact on the press filtration effect.
The second, pressing station is the core of whole hydraulic system, and all hydraulic element and energy resource supply all are contained on the Hydraulic Station, the electrical equipment of it and the electric cabinet system that composition one cover can be controlled automatically that closely cooperates.Adopt gear pump and vane pump to working connection and arm-tie loop fuel feeding providing of energy source device.
Hydraulic Station is heavy in the prior art, and oil circuit is complicated, and Hydraulic Elements are many, manually plays pump operated step complicated, is difficult for the failure judgement point.
Summary of the invention
For the too complicated technical barrier of pressurize and hydraulic station structure well of main fuel tank in the prior art, the utility model has designed Press-Filtering Machine Control System has been improved, be the two-way one-way valve structures with the one-way check valve architecture advances of main fuel tank, with the designs simplification of Hydraulic Station, finally reached well effect simultaneously.
The utility model for realizing the technical scheme that goal of the invention adopts is, a kind of follow-on U-shaped Press-Filtering Machine Control System, comprise the master cylinder and the oil motor that are connected by oil pipe with Hydraulic Station, wherein comprise two oil transportation mouths in the master cylinder, above two oil transportation mouths are by pipeline connection, in pipeline, be provided with the first hydraulic control one-way valve, the first hydraulic control one-way valve drives by solenoid directional control valve, key is: set up the second hydraulically-controlled one-way valve in above-mentioned pipeline, the first hydraulic control one-way valve and the second hydraulically-controlled one-way valve drive by solenoid directional control valve simultaneously.
Operation principle of the present utility model is that the two-way hydraulically-controlled one-way valve is controlled by solenoid directional control valve simultaneously, in case some hydraulically-controlled one-way valves are out of order, can continue to use by another hydraulically-controlled one-way valve, carries out pressurize.So just avoided the situation of prior art pressurize failure to occur.
The beneficial effects of the utility model are, foreshortened to 120-170 minute in press filtration cycle 180-240 more in the past minute, filtering cake moisture reduces to about 38% by about 55%, filter cloth satisfies the replacement cycle, effectively solve the problem that the press filtration situation is unstable and labor strength is large, provide important assurance to production run.

The specific embodiment
A kind of follow-on U-shaped Press-Filtering Machine Control System, comprise the master cylinder 2 and the oil motor 3 that are connected by oil pipe with Hydraulic Station 1, wherein comprise two oil transportation mouths in the master cylinder 2, above two oil transportation mouths are communicated with by pipeline 4, in pipeline 4, be provided with the first hydraulic control one-way valve 5, the first hydraulic control one-way valve 5 drives by solenoid directional control valve 7, and key is: set up the second hydraulically-controlled one-way valve 6, the first hydraulic control one-way valves 5 and the second hydraulically-controlled one-way valve 6 simultaneously by solenoid directional control valve 7 drivings in above-mentioned pipeline 4.
Described Hydraulic Station 1 comprises supply tank 1-1, motor M and gear pump 1-3, recovery bin 1-5, above supply tank 1-1, gear pump 1-3 are connected by oil pipe with recovery bin 1-5, output at gear pump 1-3 is connected with master cylinder 2, oil motor 3 respectively by the 3rd hydraulically-controlled one-way valve 1-6, simultaneously is provided with overflow valve 1-4 between the output of gear pump 1-3 and recovery bin 1-5.
Between supply tank 1-1 and gear pump 1-3, also be provided with oil filter 1-2.
The problem that the utility model occurs for pressure maintaining period, single-circuit hydraulic control one-way valve is improved to double loop hydraulic control one-way valve pressurize, when the pressurize effect can't be played in the oil-feed loop, oil-feed loop and oil return circuit are exchanged, can play pressure maintaining effect equally, maintenance is convenient, changes with bad check valve in the situation that do not affect production, effectively avoids suspending the possibility of production run.In order to reduce vane pump in the oil supply loop and the motor of its coupling, be about to the double pump fuel feeding and be improved to single oil pump feed loop, the oil circuit that obtains like this is simple, easy failure judgement point, without check valve, maintenance is convenient.
