Description
Technical field
The utility model relates to high purity graphite production system, particularly relates to a kind of high purity graphite continuous process system.
Background technology
Along with deepening continuously of Economic development, thick spacious type economized form has changed Intensive economy development pattern into, unexpectedly strives aggravation, and enterprise profit declines, and internal strength must be practiced by enterprise, cost declining, improves quality, walks the road of economical environment-protective, walk the Road of Cyclic Economy; Just can establish oneself in an unassailable position, could sustainable development.
Over nearly 30 years, Chinese infrastructure investment is too fast, causes the imbalance of development, and the contradiction of some other profound level, and the most outstanding is iron and steel, cement, production of construction materials cross Sheng, industrial profit is sharply declined, directly affects the development of graphite industry.Natural graphite is non-renewable resource, and be a kind of strategic materials of country, China recognizes its importance already, and takes corresponding sfgd., as restricted export, and planned exploitation etc.For the problem of the environmental pollution of the deep processing of graphite, State Council has put into effect more severe policy, finds that there is firmly closing down of the event of polluting, further protection of the environment, decreasing pollution.
Enterprise thinks that existence just must cost declining in this context, takes appropriate measures simultaneously, protection of the environment, energy-saving and emission-reduction.The purification of natural graphite is the basis of graphite deep processing; graphite purity all must first improve by all graphite high, precision and frontiers, product; therefore the production of high purity graphite and high-carbon graphite is the basis of graphite deep processing; under present social environment, only have experienced internal strength, cost declining, protection of the environment, energy-saving and emission-reduction, meeting social development requirement could survival and development.
The applicant once proposed a kind of continuous production device of high purity graphite chemical purification, it comprises a group reaction tank, each retort discharge port leads to same hopper, hopper one end is water-in, the other end leads to one group of flotation machine, each flotation machine inwall polypropylene lining plastics, and flotation unit connects a vacuum filter, vacuum filter connects a dryer by a worm conveyor, and dryer connects screening sieve.Although the arrangement achieves continuous seepage, improve production efficiency, cost is still very high, and in addition, sour large usage quantity, exists certain acid pollution.
Summary of the invention
The utility model is intended to the defect overcoming prior art, provides a kind of high purity graphite continuous process system with preprocessing function.The utility model can reduce sour consumption, reduces cost for wastewater treatment, decreasing pollution.
In order to solve the problems of the technologies described above, a kind of continuous process system with the high purity graphite chemical purification of preprocessing function, it comprises a group reaction tank, each retort discharge port leads to same hopper, hopper one end is water-in, the other end leads to a depickling pressure filter, and the waste water that depickling pressure filter produces returns retort secondary recycling by an in-line pump, and described pre-filtering equipment is with the sour circulating line leading to retort entrance.
The material that depickling pressure filter produces then is entered in flotation machine by spiral carrier pipe and carries out flotation washing, material after flotation washing enters in dryer by screw feeder again, the material that dryer produces enters in subhead machine and carries out sieving subhead, obtains the high purity graphite that specification is different after subhead.
The described continuous process system with the high purity graphite chemical purification of preprocessing function, it also comprises the screening subhead machine of a connection dryer.
The described continuous process system with the high purity graphite chemical purification of preprocessing function, described pre-filtering equipment is selected from the one in pressure filter, suction filtration machine, whizzer, deep bed filter.
The described continuous process system with the high purity graphite chemical purification of preprocessing function, described strainer is selected from the one in pressure filter, pressure filter or whizzer.
The described continuous process system with the high purity graphite chemical purification of preprocessing function, described flotation machine assembly housing is all made with vinyon plate; Inner flotation impeller adopts rubber wheel, can prevent acid liquid corrosion, improves work-ing life.
The utility model improves on the basis of existing high purity graphite continuous production device, optimize, one pre-filtering equipment is added before flotation washing plant, object is that retort material out is first filtered one time, and the spent acid solution filtered out is collected, put into production recycling, can reduce environmental protection treatment workload, also can reduce costs, improve the quality of products; This device is after adding filter recovery acid solution recycling, and acid adding ratio originally can reduce half, and production cost can reduce by 1/3, and cost for wastewater treatment also can reduce by 1/3, and this device puts into production use and has considerable economic benefit and social benefit.
Accompanying drawing explanation
Below, by reference to the accompanying drawings the utility model is further described
Fig. 1 is the utility model schematic diagram.
