Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the work flow diagram of the utility model.
Specific implementation mode
As shown in Figure 1, 2, a kind of graphite high yield high yield chemical purification device, including the 1, press filtration of primary first-order equation tank
It is 2, agitator tanks 3 of machine, dehvery pump 4, recycling filter press 5, product collecting cart 6, secondary response tank 7, secondary filter press 8, secondary
Agitator tank 9, three times filter press 10,1 output end of primary first-order equation tank are connect by dehvery pump 4 with 2 input terminal of filter press,
2 output end of filter press is connect with an agitator tank 3,3 output end of an agitator tank by dehvery pump 4 with it is secondary
Retort 7 connects, and 7 output end of secondary response tank is connect by dehvery pump 4 with secondary filter press 8, the secondary filter press 8
Output end is connect with secondary agitation tank 9, and 9 output end of secondary agitation tank is connect by dehvery pump 4 with filter press 10 three times, institute
10 output end of filter press three times is stated to connect with product collecting cart 6；Filter press 2, secondary filter press 8, three times filter press
10 washes liquid mouth is connect by dehvery pump 4 with recycling filter press 5, and 5 output end of recycling filter press is received with product
Collect vehicle 6 to connect.
The operation principle of the utility model：Graphite material and acid are added in primary first-order equation tank 1 by a certain percentage, heated condition
Under chemically reacted, reaction, which terminates to open dehvery pump 4, squeezes into completely reacted clinker slurry in filter press 2, through pressure filtering cleaning
It washs rear material to be discharged into an agitator tank 3, graphite material and water are squeezed by dehvery pump 4 secondary in an agitator tank 3 after mixing
In retort 7, material and mixed acid are mixed in a certain ratio the uniformly secondary chemical reaction of heating generation in secondary response tank 7,
Squeezed into secondary filter press 8 by dehvery pump 4 after the completion of reaction, material it is washed in secondary filter press 8 and squeeze after enter two
In secondary agitator tank 9, material adds pure water and is squeezed into after dilution in filter press 10 three times in secondary agitation tank 9, after washed squeezing
It obtains high purity graphite product and enters in product collecting cart 6 to be put in storage.Because of a press filtration, secondary press filtration, press filtration is used three times
Filter cloth be 1000 mesh, corresponding aperture is 13 microns, then is less than 13 microns of graphite particle by filter cloth mesh with washing
Waste water enters in recycling filter press 5, and it is 2200 mesh to recycle the filter cloth in filter press 5, and aperture is 5 microns, can be by 5 microns or more 13
Micron particle below is gathered and passed through wash press again, obtains the graphite products of high-purity, the product after graphite squeezing is certainly

The utility model compared with the prior art, uses the technical solution of innovation：
Secondary centrifuging washing is changed to the comparable filter press of price, is changed to pressure filtration washing, primary charging can reach
1.5-2 tons, a tank material only needs press filtration twice, and entire press filtration, washing, squeezing, blowing process are about 2.3 hours, press filtration processing one
Tank material only needs 4.6 hours, greatly improves yield in the unit interval, and inlet amount is 5 times of filter press one of centrifuge
Platform price is only that the price of a desk centrifuge is suitable.Save the cost that equipment is disposably put into.
It is changed to after filter press because of one time that inlet amount is larger, washing effect can be impacted, especially the trace element of material,
It is easily exceeded due to washing is not thorough.Following method is taken further to solve：Increase on the basis of secondary pressure filtration washing dilute together
Process and three times press filtration are released, the material washing effect of not thorough washes clean can be made to improve, makes the reduction of impurity trace element, reaches
To product acceptance criteria.
The problem of being improved for yield also adds one of recovery processing process in utility model device, can make three
Filtration washing recycling comes up fine particle (particle for being less than filter cloth mesh) in secondary pressure-filtering process again.It is whole to improve
Yield.Concrete scheme：By the waste collection of press filtration three times, waste liquid is squeezed into the filter press of the 2200 mesh filter clothes equipped with mesh 5um
Middle press filtration, with pure water, then through squeezing, discharging be recycled product after testing its purity up to qualified products standard,
Whole yield can be greatly improved.
In addition, it is 15us/cm pure water below, the primary first-order equation tank of whole device that secondary response, washing, which are all made of purity,
1, an agitator tank 3, secondary response tank 7, secondary agitation tank 9 ensure that material is high-purity using the equipment container of PP or PPR materials
Degree, trace element be not exceeded.
