As shown in figure 1, a kind of separation of coarse slime classifying integrated machine includes：Water Jie cyclone separator 1 and eddy flow dewatering screen 2.
Water Jie cyclone separator 1 includes cylindrical shape stack shell 11, is sealedly connected on the conical tube of the bottom of cylindrical shape stack shell 11
Bottom 12 and the cover 13 for being sealedly connected on the top of cylindrical shape stack shell 11, the axis of cylindrical shape stack shell 11 and the axle at conical tube bottom 12
Line overlaps.Feed pipe 14 is provided with the side wall of cylindrical shape stack shell 11, underflow discharge pipe is provided with conical tube bottom 12
15, overflow pipe 16 is provided with cover 13.
Eddy flow dewatering screen 2 includes cylindrical shape sieve nest 21 and is fixedly connected on the cone sieve bottom of the bottom of cylindrical shape sieve nest 21
22, the axis of cylindrical shape sieve nest 21 overlaps with the axis at cone sieve bottom 22.Cylindrical shape sieve nest 21 side wall on be provided with
Feeding pipe 23, feeding pipe 23 and overflow pipe 16 connect, water Jie cyclone separator 1 to be connected with eddy flow dewatering screen 2, cone
Discharge chute 24 is provided with sieve bottom 22.
Specific work process is：Coarse slime ore pulp enters cylindrical shape stack shell with certain pressure by Pulp pump by feed pipe 14
Inside 11, after pressing density separation to coarse slime ore pulp in the inside at cylindrical shape stack shell 11 and cone sieve bottom 22, density is larger
Part is discharged by underflow discharge pipe 15, then product of coal in being formed after being dehydrated by external equipment.The less part of density passes through
Overflow pipe 16, the inside of eddy flow dewatering screen 2 is entered by feeding pipe 23 and (sieves the interior of bottom 22 into cylindrical shape sieve nest 21 and cone
Portion) carry out predrainage, it is supporting that oversize after dehydration enters back into sieve bend, high frequency shale shaker etc. after discharging by discharging chute 24
Dehydration is carried out in equipment and forms head coal product.Using such technical scheme, coarse slime ore pulp is directly carried out after being sorted
Predrainage, reduces the flow for the oversize discharged via discharge chute 24, while also improves concentration, so as to alleviate arc
The work load of the corollary equipments such as sieve, high frequency shale shaker, improves dehydrating effect, product quality is guaranteed.
Preferably, tangent line or involute of the feed pipe 14 along the cross circular section of cylindrical shape stack shell 11 are set, underflow discharge pipe 15

23 link position is the top of cylindrical shape sieve nest 21, can so improve the pressure that bottom 22 is sieved in the overflow to cone, enter one
Step improves dehydrating effect.Discharge the axis vertical setting that chute 24 sieves bottom 22 along cone.The row of oversize can be advantageous to
Go out, avoid being formed on cone sieve bottom 22 and accumulate.
It should be noted that between feed pipe 14 and cylindrical shape stack shell 11, underflow discharge pipe 15 and conical tube bottom 12 it
Between, it can use flange connection etc. is dismountable to be tightly connected mode between cylindrical shape stack shell 11 and conical tube bottom 12, this
Sample is advantageous to the disassembly and installation of water Jie cyclone separator 1, is brought conveniently to service work.As a same reason, feeding pipe 23 with
Between cylindrical shape sieve nest 21, discharge between chute 24 and cone sieve bottom 22, between cylindrical shape sieve nest 21 and cone sieve bottom 22
It can also use flange connection etc. is dismountable to be tightly connected mode, its action effect is identical with water Jie cyclone separator 1.
Because coarse slime ore pulp is entered inside cylindrical shape stack shell 11 by Pulp pump with certain pressure by feed pipe 14, in reality
Pressure is 0.05-0.15Mpa in the work of border, therefore can be to be provided with pressure gauge 141 on feed pipe 14, to monitor coarse slime ore pulp
Entrance pressure, avoid the occurrence of hypertonia or too low phenomenon and occur.
More preferably, can the inwall of cylindrical shape stack shell 11, the inwall at conical tube bottom, feed pipe 14 inwall and
High-abrasive material (such as ceramics) is laid on the inwall of underflow discharge pipe 15, to extend the service life of water Jie cyclone separator 1.
As a kind of embodiment, the separation of coarse slime classifying integrated machine also includes top cover 31 and leading with upper port
Flow cartridge 32.Mozzle 33 is provided with the bottom of guide shell 32, eddy flow dewatering screen 2 is arranged on the inside of guide shell 32, top cover 31
