Description
Technical field
The present invention relates to a kind of solid-liquid separating machine, a kind of specifically solid-liquid separating machine of handling tail mud of tailings.
Technical background
Mine tailing is raw ore depleted finely powdered solid materials after ore dressing or other technology reclaim useful component of mining, usually with ore dressing process in the water that consumes with the form of mine tailing slurry from inflow mine tailing storehouse, dressing-works.Contain a large amount of valuable mineral compositions in some mine tailing, or even rare metal and noble metal composition, for various reasons, it all can't be selected only, it is emitted on causes valuable resource element waste in the mine tailing in the mine tailing storehouse.The mode that the mine tailing storehouse adopts the interception mouth of a valley or exclosure to build a dam is usually built up, it is an artificial rubble flow dangerous matter sources with high potential energy, have dam break danger, mine tailing is in case accident will cause huge disaster and loss to industrial and agricultural production and downstream people's lives and properties.Numeral according to China relevant department statistics, the existing mine tailing of China has taken up an area of about 3000km2, this is very disadvantageous for the country that is had a large population and a few land as China, mine tailing such as untimely processing, not only take a large amount of farmlands and forest land, and can cause severe contamination to air, water body through wind and weather, the physical environment around destroying produces very big harm to the mankind.Therefore actively develop processing research, not only can avoid above situation, and can produce certain economic benefits by making product to mine tailing.With solids in the mine tailing and water sepn, can utilize again it, the existing mode that filter adopted that is used to handle mine tailing is that filter cloth filters, efficient is low, energy consumption is high, complex structure and separate not thorough, the filtrate muddiness, and filter cloth is fragile, has increased use cost, therefore need provide that a kind of separations is thorough, simple in structure, energy consumption is low, and be suitable for the solid-liquid separating machine of various dressing-works, coal separating plant and power plant's processing pulpous state tailing.
Summary of the invention
The objective of the invention is deficiency, a kind of solid-liquid separating machine that dressing-works, coal separating plant and power plant handle the pulpous state tailing that is used for is provided for solving the problems of the technologies described above.
The present invention is the deficiency that solves the problems of the technologies described above, the technical scheme that is adopted is: a kind of solid-liquid separating machine of handling tail mud of tailings, comprise separate tank, filtering table and vacuum pump, at least be provided with a filtering table in the separate tank, filtering table is the splicing of segmental filter and forms by filtering plate rail and being symmetricly set on to filter on the plate rail, be hollow structure between two symmetric filters, the bottom of filter and gas-liquid circulation exchange pipe coupling, gas-liquid circulation exchange pipe is connected with vacuum pump by distribution valve, and filtering table is arranged in the rotating shaft at separate tank edge.
The present invention, described filtering table has 2～12.
The present invention, described filter is made of two-layer silicon carbide absorption plate, is evenly equipped with the pore of 2～10 μ m on the silicon carbide absorption plate.
The present invention is provided with agitator in the described separate tank.
The present invention, described separate tank, its edge outwards protrude and are provided with the groove that matches with filtering table, and the both sides of groove are provided with the trowel of scraping with joint, filtering table side.
The present invention, described groove is connected with wash pipe.
The present invention, described groove below is provided with funnel and reclaimed materials conveying belt.
The present invention, described distribution valve is connected with the water purification recovery tube.
The present invention, the ore pulp that needs is carried out solid-liquid separation injects separate tank, the rotating shaft that is connected with motor drives filtering table and rotates in separate tank, distribution valve control gas-liquid circulation exchange pipe vacuumizes when filter immerses ore pulp, stop to vacuumize when going to the scraper at separate tank edge, and injection water purification, the inner negative pressure that produces of filter when vacuumizing, can reach-0.91MPa, water in the ore pulp is because wicking action enters filter by pore, recycled by the water purification recovery tube, the solid isolate then rests on the filter outside, forms filter cake, filter go to the separate tank edge scrape trowel the time, water oozes out from pore, is beneficial to peeling off of filter cake, can reduce the wearing and tearing of filter.The stirring that the agitator that is provided with in the separate tank does not stop prevents ore pulp deep gouge phenomenon, and the filter cake that strips down falls into the reclaimed materials conveying belt through funnel, can realize working continuously.
The invention has the beneficial effects as follows:
1, good effect of separating solid from liquid, filtrate is limpid, can directly utilize.
2, low, the power consumption of energy consumption only is the 10%-20% of traditional filtering machine.
3, automatic continuous operation, maintenance cost is low.
4, filter long service life, replacing are easily.
5, compact equipment, convenient operating maintenance has reduced cost.
6, environmental protection, pollution-free.
