Abstract
The utility model discloses a horizontal helical unloading and depositing centrifuge, which is characterized by comprising a casing, a rotating drum, a helical conveyor, a differential mechanism, a transmission and a feeding pipe. The horizontal helical unloading and depositing centrifuge has the advantages that coarse grains are deposited on the internal wall of the rotating drum under the centrifugal force after pulp enters in the helical conveyor by the feeding pipe; filtrate directly flows out of an overflow hole arranged on a left end plate of the rotating drum; and as the differential mechanism is arranged between the helical conveyor and an output shaft of the transmission, the rotating speed of the helical conveyor is slightly lower than that of the rotating drum so that the coarse grains deposited on the internal wall of the rotating drum are directly pushed out of a coarse grain outlet arranged on a right end plate of the rotating drum, thus effectively improving the production efficiency.
Description
Technical field
The utility model has related to a kind of being used for production process of titanium pigment has been carried out the equipment that classification is handled to the titanium dioxide particulate, particularly a kind of horizontal spiral discharge sedimentation centrifuge.
Background technology
TiO 2 pigment after wet-milling, before surface treatment, in order further to obtain the TiO 2 pigment dispersion of certain grain size distribution scope, also need to carry out classification, because general pigmentary titanium dioxide does not wish to exist the coarse granule more than the 5 μ m, the chemical fibre delustring does not wish to have bulky grain more than the 2 μ m with titanium dioxide, also can remove the mechanical admixtures such as fine sand that ground once in a while by classification simultaneously.
Classification has two kinds of dry method and wet methods usually:
Above hierarchical approaches, fineness from classification, centrifugal classifying is best, and screen fractionation is the poorest, and its arrangement is roughly as follows: centrifugal classifying is better than hydrocyclone, cyclone is better than general mechanical type wet classification device as spiral, rake formula etc., centrifugal gas dry classification device, suitable substantially with the grading effect of hydrocyclone, under the situation of not considering open-minded property, better than hydrocyclone outline, sieve method generally can only classification to about 400 orders.
Compare with dry method, the separating rate of wet classification is slower than dry method, energy consumption is high, but it can make pigment particles remain dispersity when classification, and do not resemble to slit the dry method and be attached to together, the surface treatment process that adds titanium dioxide adopts wet processing, therefore in the titanium dioxide industry, all adopt wet classification technology and wet classification equipment.
Wet classification equipment can divide the gravity-type settling classifier as wet concentration jar, thickener, Dao Er type settling vat etc.; Centrifugal clasfficiator is as hydrocyclone, decaner etc., and the wet method mechanical type classifying equipoment as the vibratory sieve.
The gravitational settling clasfficiator, it is main in the early stage factory of China that what use is the wet concentration jar, according to Stokes Stokes formula, calculate the settling height and the sedimentation time of selected particle diameter particle, then under the time of the height of appointment and appointment the suspension of two kinds of different-grain diameters separately.If with the rutile titanium dioxide is example, when being decentralized medium with water, vigorous degree η=0.01 pool of water when room temperature, relative density P=1, the relative density of rutile titanium dioxide is 4.2, gravity acceleration g=981cm/s
2, U=69.760r then
2If, be the particle diameter calculating of 5 μ m with diameter of phi, substitution following formula υ=15.7cm/h, promptly 4min/cm that is to say that diameter is the rutile titanium dioxide particle of 5 μ m, the height of every sedimentation 1cm needs the time of 4min.
Cross the titanium dioxide production factory gravitational settling of going abroad and generally adopt Dao Er type waterpower settler (Dorr Hydroseparator), its principle is similar to general Dao Er type settling vat, mainly come classification by the speed of control overflow, the rate of climb of generally controlling slurries is about 15cm/h.1 settling area 16m
2, settling height 2.7m continuous gravitational settling clasfficiator, the classifying capability of every day is the 20t TiO 2 pigment, can not contain the above bulky grain of 6 μ m in the overflowing liquid, and this equipment can continued operation, but the equipment heaviness, floor space is big, concentration of slurry is rare, seldom adopts at present.
