Description
Technical field
The present invention relates to a kind of ore pulp filter press, specifically refer to that magnetic moves air-sweeping type ore pulp filter press.
Background technology
Hydrometallurgy is the processing and utilization mode of carrying out lixiviate after ore being broken into powder, and the ore pulp after lixiviate needs to carry out press filtration, and thus filter press carries out the very important equipment of Separation of Solid and Liquid in hydrometallurgy process.In hydrometallurgical processes, be all generally relatively large filter press hydraulic compression, carry out hydraulic pressure expansion deckle board inner septum after having filtered, realize extruding of expanding, content liquid in filter residue is reduced as far as possible, reduce solubility loss of effective components.
But the liquid still containing about 30% in the ore pulp filter residue of overexpansion extruding, liquid residual in ore pulp filter residue not only can make the yield of hydrometallurgy reduce, if discharge also can serious environment pollution.Owing to needing the ore pulp amount of carrying out press filtration very large in hydrometallurgical processes, thus reduce the residual quantity of liquid in ore pulp filter residue, just can significantly energy-saving and emission-reduction.
But existing ore pulp filter press does not all have to solve this technical problem more easily, although filter residue can blow more dry with air by the filter press of some field of food, but need the artificial water nozzle of turning on or closing on filter press plate one by one in air-blowing process, very loaded down with trivial details, the workload of workman is very large, particularly during ore pulp press filtration, because filtration yield is huge, general have up to a hundred taps, and ore pulp is mostly through soda acid process, have corrosivity and toxicity, thus manual operation not only bothers, and very dangerous.
Therefore, existing filter press can not meet the requirement of people for ore pulp press filtration, needs the feature for ore pulp, improves.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, for the feature of ore pulp, provides a kind of magnetic that conveniently can reduce specific retention in ore pulp filter cake to move air-sweeping type ore pulp filter press.The design is carrying out after hydraulic diaphragm extracts filter cake, using compressed air to realize air-flow and penetrating filter cake, carry fluid, reduce filter residue specific retention, improve filter residue liquid outlet quantity.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
A kind of magnetic moves air-sweeping type ore pulp filter press, comprise the filter press be made up of ore pulp import, filter press plate, hydraulic power unit and hydraulic jack, it is characterized in that: by stirring motor, reductor, the stirring chemical combination bucket that mixer base, shaft and stirring vane form is connected the ore pulp import of filter press through filter pressing pump, check valve; Be connected the ore pulp import of filter press through intake valve by air compressor machine and the air blowing device formed with air accumulator; Common water nozzle and magnetic dynamic control water nozzle are installed in filter press plate interval, the dynamic water nozzle that controls of magnetic comprises plastic jacket, steel disk, lock nut, swivel nut, valve rod, valve body, hickey, drain pipe, spool and plug screw, hickey realizes the connection with filter press plate, swivel nut plays effect of contraction to valve rod and is convenient to valve rod and moves up and down flexibly, when steel disk moves upward by magneticaction, valve seat upwards can be coordinated to close fluid course by valve rod band movable valve plug, when magnetic force is removed, spool can free-falling under gravity, makes valve opening; Magnetic dynamic control is provided with magnetic stripe substrate near water nozzle, and magnetic stripe substrate is provided with magnet, magnetic stripe substrate connecting handle, and operating grip just can drive magnet to be toward or away from magnetic dynamic control water nozzle.Namely magnetic field is near closing water nozzle, and magnetic field is left and just opened water nozzle, realizes Magnetic Control water nozzle switch.
Described air accumulator is provided with safety valve and Pressure gauge, is convenient to safe handling.
During press filtration operation, by filter pressing pump transfer ore pulp, enter magnetic through check valve to move air-sweeping type filter press and carry out press filtration, the common water nozzle that filtrate is installed by interval and the dynamic water nozzle that controls of magnetic are discharged, being reduced to a certain degree explanation filtration end when going out flow quantity, stopping filter pressing pump, carry out hydraulic pressure expansion deckle board inner septum, realize extruding of expanding, content liquid in filter residue is reduced.
Expand at the end of extruding, operating grip makes magnetic stripe substrate close to magnetic-control water discharge-nozzle, and common water nozzle maintenance is unimpeded but magnet on magnetic stripe substrate controls water nozzle Close All by dynamic for magnetic, forms water nozzle interval and opens.
Air blowing device is added in the design, open the valve on air blowing device, compressed air can enter filter press along pipeline by ore pulp import, air is stronger through filter cake ability, boosting is assembled in the filtrating-pressing plate frame that magnetic moves the closedown of control water nozzle, pressure raises the pressure reduction that just can be formed and often open between common water nozzle filtrating-pressing plate frame, pressure reduction makes air pass filter cake between two sheet frames, realize air extrusion, pass, carry, liquid in filter residue is discharged by often opening common water nozzle, realize filter cake to dry up, reduce content liquid in filter cake further.
Compared with prior art, beneficial effect of the present invention is:
Do not have large change to common filter press, the convenient compressed air that realizes dries up operation, and the slag filter cake specific retention after drying up only has 20%, reduces by 1/3rd than do not carry out drying up operation 30%, can significantly energy-saving and emission-reduction, raising yield; It is ingenious that magnetic moves valve simplicity of design, just can control whole row's magnetic-control water discharge-nozzle with a handle simultaneously, greatly reduces the labour intensity of press filtration operation breaker in middle water nozzle, also improves the security of operation; It is more simple and reliable than electromagnetic valve structure that magnetic moves valve, is difficult to blocking, also do not need electric wire and power supply, use very easy.
