Description
Technical field
The utility model relates to the efficient filter-pressing device in a kind of electrolytic zinc technique.
Background technology
Electrolytic zinc is carried out by zinc ore pulverizing, chemical combination, removal of impurities, carries out the hydrometallurgy process of electrolysis after allotment again, needs to remove solid slag by press filtration, to obtain the solution needed for electrolysis after chemical combination completes.Therefore, press filtration is very important unit step in electrolytic zinc technique.
Press filtration in electrolytic zinc technique, general is all plate and frame(type)filter press, and select impeller pump as filter pressing pump, pressure-filtering process obtains filtrate, filter residue progressively runs up to optimal filling degree in pressure filter simultaneously, carry out respective handling again, finally complete the cyclical operation process of filter residue cleaning, the object of press filtration realizes solid-liquid separation exactly.In the starting stage of press filtration operation, owing to being complete empty in pressure filter, concerning filter pressing pump, the quick large discharge input carrying out less lift is the ideal operation state of now press filtration operation; But increase along with filter cake accumulates rear resistance in pressure filter, when particularly stopping close to press filtration, have peak pressure expanded state, therefore, larger lift can be had to be to best requirement by the press filtration performance of pressure filter in press filtration the second half.
But in press filtration operation, existing impeller pump all cannot adapt to such process automatically, reaches efficient, high-quality ideal operation state.When general impeller pump carries out press filtration operation, be all that the early stage lift of press filtration is lower, but flow is large, makes motor be in overload, especially easily motor damage; To the press filtration middle and later periods, press filtration resistance strengthens rapidly, and the flow quantity of impeller pump reduces rapidly, although at this moment motor is operated in the low power state of underloading, efficiency of press filtering is very low; Although filter pressing pump has H-Max output state, because pressing filtering liquid flow is less, the serviceability of pressure filter cannot be given full play to and increase work efficiency.
Therefore, impeller pump is made to coordinate pressure filter, the press filtration whole process in electrolytic zinc technique is made all to reach ideal operation state, the optimum performance playing press filtration is difficult to realize, if but look for another way, adopt the free shifter of two impeller pump series and parallels to complete press filtration work, make it in press filtration in early days by two impeller pump parallel connections, realize fast, less energy-consumption, the efficient press filtration of large discharge; In press filtration, two impeller pumps are connected by latter stage, obtain high-lift transport capacity, after meeting, journey press filtration resistance is large, but still applicable flow can be had to embody efficient press filtration and give full play to the feature of pressure filter performance, so free shifter of two impeller pump series and parallels is adopted to break through pressure filtering technique bottleneck in electrolytic zinc technique, reach the ideal operation state of press filtration, there is the actual application value of particularly important.
Utility model content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art exactly, and provide the efficient filter-pressing device in a kind of electrolytic zinc technique, this apparatus structure is simple, practical, and the series and parallel that can realize two centrifugal pump device freely switches.
For overcoming the deficiencies in the prior art, the utility model takes following technical scheme:
An efficient filter-pressing device in electrolytic zinc technique, comprises inlet pipe, goes out pipe, two impeller pumps and two pressure filter, it is characterized in that: two impeller pumps pass through belt transmission by same motor; Inlet pipe branches into two pipelines, and a pipeline is connected pipe through three-way tap with impeller pump, and another pipeline is connected pipe through another impeller pump with another three-way tap; The upper and lower UNICOM of union in two three-way tap warps; Inlet pipe connects zinc solution chute, and chute has the bottom construction of back taper; Connect pipe after two pressure filter parallel connections, two branch roads in parallel are equipped with control valve.
This device, by swivel tee cock, can realize freely switching of two impeller pump series and parallel structures, the press filtration in electrolytic zinc technique can be made to operate and reach optimum Working.
Compared with prior art, the beneficial effects of the utility model are also:
The optimum working performance reaching impeller pump needed for press filtration in electrolytic zinc technique is switched by the series and parallel of impeller pump; The free blocked operation of series and parallel of two impeller pumps is achieved by rationally succinct circuit design and three-way tap; Compared with the series and parallel pipeline valve shifter of routine, threeway plug valve can greatly reduce the consumption of pipeline and valve, and simplifies the blocked operation of series and parallel, avoids the mistake occurred in common pipe valve system series and parallel handoff procedure; The chute cone end of back taper, be conducive to the outflow of zinc solution; Two pressure filter parallel connections are convenient to wherein in a pressure filter cleaning filter residue process, and another pressure filter still normally can carry out press filtration.
The utility model structure is simple, and cost is low, practical, has a extensive future.
