Description
Technical field
The present invention relates to a kind of pump circulation anti-blockage type and basic magnesium carbonate is carried out the device of efficient filter pressing.
Background technology
Basic magnesium carbonate is one of most important compound in magnesium industry processed, is widely used as the additive of toothpaste, paint, cosmetics, plastics, rubber etc..Generally, basic magnesium carbonate can be obtained by pyrolysis, i.e. pyrolysis magnesium bicarbonate obtains, and its dominant response mechanism is 2Mg (HCO3) 2=Mg2 (OH) 2CO3+3CO2+H2O.
In modern industry, the main method using pyrolysis magnesium bicarbonate solution to be i.e. pyrolyzed heavy magnesium water produces basic magnesium carbonate, heavy magnesium water needs to carry out filter pressing after being pyrolyzed could obtain product, the filter pressing of basic magnesium carbonate, it is typically all plate and frame type filter-press, and select centrifugal pump as filter pressing pump, pressure-filtering process is to obtain filtrate, filtering residue progressively runs up to optimal filling degree in pressure filter simultaneously, carry out respective handling again, finally completing the circulation operating process of filtering residue cleaning, the purpose of filter pressing realizes solid-liquid separation exactly.In the starting stage of filter pressing operation, owing to being complete empty in pressure filter, for filter pressing pump, the biggest flow input carrying out less lift is the ideal operation state of now filter pressing operation；But after accumulating in pressure filter along with filter cake, resistance increases, and has maximum pressure expanded state, therefore, bigger lift can be had to be to optimal requirement by the filter pressing performance of pressure filter in filter pressing the second half when particularly terminating close to filter pressing.
But in filter pressing operates, existing centrifugal pump all cannot adapt to such process automatically, reaches efficient, high-quality ideal operation state.When general centrifugal pump carries out filter pressing operation, it is all that filter pressing lift in early days is relatively low, but flow is big, makes motor be in overload, is particularly easy to motor damage；To filter pressing middle and late stage, filter pressing resistance strengthens rapidly, and the flow quantity of centrifugal pump reduces rapidly, although at this moment motor is operated in the low power state of underloading, but efficiency of press filtering is the lowest；Although filter pressing pump has H-Max output state, but owing to pressing filtering liquid flow is less, it is impossible to give full play to the service behaviour of pressure filter and improve work efficiency.
Therefore, centrifugal pump to be made coordinates pressure filter, basic magnesium carbonate filter pressing whole process is made all to reach ideal operation state, the optimum performance playing filter pressing is difficulty with, if but look for another way, the convenient switching device using two centrifugal pump series and parallels completes filter pressing work so that it is in filter pressing in early days by two centrifugal pump parallel connections, it is achieved quickly, low energy consumption, big flow-quantity high-efficiency filter pressing；In filter pressing, two centrifugal pumps are connected by after-stage, obtain high-lift conveying capacity, after meeting, journey filter pressing resistance is big, but still applicable flow can be had to embody efficient filter pressing and give full play to the feature of pressure filter performance, the such pair of convenient switching device of centrifugal pump series and parallel is used to break through the pressure filtering technique bottleneck of basic magnesium carbonate, reach the ideal operation state of filter pressing, there is the actual application value of particular importance.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, it is provided that basic magnesium carbonate is carried out the device of efficient filter pressing by a kind of pump circulation anti-blockage type, and this apparatus structure is simple, practical, can realize the convenient switching of series and parallel of double centrifugal pump device.
For overcoming the deficiencies in the prior art, the present invention takes techniques below scheme:
Basic magnesium carbonate is carried out the device of efficient filter pressing by a kind of pump circulation anti-blockage type, including inlet pipe, goes out pipe, two centrifugal pumps and basic magnesium carbonate pressure filter, it is characterised in that: two centrifugal pumps are passed through belt transmission by same motor；Inlet pipe branches into two pipelines, and a pipeline connects pipe through three-way cock and centrifugal pump, and another pipeline connects pipe through another centrifugal pump and another three-way cock；Two three-way cocks are equipped with gear driven Spool rotating, and the gear of two three-way cocks engages each other and has driving gear to drive one, it is achieved the rotation switching of two three-way cocks, the upper and lower UNICOM of union in two three-way cock warps；Inlet pipe connects basic magnesium carbonate surge tank through valve, and basic magnesium carbonate surge tank has the polycrystalline substance of inverted cone, in the middle part of surge tank and is provided with the outer circulation blockage resisting loop of pipeline and circulating pump composition at cone the end；Go out pipe and connect basic magnesium carbonate pressure filter.
This device is rotated by driven by motor driving gear, can single-power gear-linked stroke, the most fast switch manipulation, the convenient switching realizing two centrifugal pump series and parallel structures, can make basic magnesium carbonate filter pressing operation reach optimum Working.
Compared with prior art, beneficial effects of the present invention also resides in:
Switched by the series and parallel of centrifugal pump and reach the optimum working performance of centrifugal pump needed for basic magnesium carbonate filter pressing；By the most succinct circuit design and single-power gear-linked stroke, the most fast switch manipulation, the ingenious series and parallel handover operation being achieved two centrifugal pumps by two three-way cocks；Compared with conventional series and parallel pipeline valve switching device, threeway plug valve can greatly reduce the consumption of pipeline and valve, and simplifies the handover operation of series and parallel, it is to avoid the mistake occurred in common pipe valving series and parallel handoff procedure；Being conducive to charging at the bottom of the cone of inverted cone, outer circulation blockage resisting loop can effectively prevent feed blocking, beneficially the carrying out of filter pressing.
Present configuration is simple, and low cost is practical, has a extensive future.
