Abstract
The utility model discloses a device used for crushing material below kiln of titanium white device in sulfuric acid method of titanium white, which comprises a roller press (1), a slurry storing tank (4), a feeding pump (5) and a grinding machine (6) that are connected sequentially. The utility model is characterized in that: a wetting tank (2) and a ceramic ball mill (3) are connected sequentially between the roller press (1) and the slurry storing tank (4); an inlet of wetting tank (2) is connected with an outlet of the roller press (1); and a material outlet of the wetting tank (2) is connected with a material inlet of the ceramic ball mill (3). According to the utility model, the fineness of the material below kiln after crushing and wetting reaches a standard that 100% of the material is less than 40 mu m. Therefore sufficient coating processing can be performed to the surface of the pigment particles, and the pigment quality of the titanium white is greatly improved.
Description
Technical field
The utility model belongs to chemical products production equipment technical field, especially relates to a kind of preceding equipment of pulverizing of titanium white sulfuric acid method titanium pigment device calcining kiln blanking that is used for.
Background technology
Titanium dioxide (being commonly called as the kiln blanking) in sulfuric acid method titanium pigment device production process after the process calcining is aggregation and the sinter that differs in size, and its size distribution is approximately:
| ≥3mm | 3～2mm | 2～1mm | ≤1mm |
| 7.59％ | 22.10％ | 21.84％ | 48.47％ |
These aggregations and sinter can not demonstrate fully the optical property and the pigment performance of titanium dioxide excellence, must could embody its optical property and pigment performance by being crushed to its original basic pigment size (about 0.15～0.45 μ m).Produced once simple particle when basic pigment particles is titanium dioxide hydrolysis, and during calcining, gradually grow up and be basic granules of pigments, then at high temperature sintering flocks together, the aggregation of just broken these the basic pigment particles of crushing process, so-called preceding the pulverizing.
Titanium white powder pigment is to improve its weather resisteant and dispersiveness before being packaged into product, generally can coat the optical defect of one deck coating layer with the elimination TiO 2 particles on pigment particles, and improve the weather resisteant and the dispersiveness of its application.So-called surface treatment of this process or coating, and surface treatment or outside in the membrane process optimal state be the coating agent to be wrapped on each simple particle, only in this way finish could guarantee that coating layer is all arranged on each particle when the back is separated with fixed attention with the steam flow pulverizer at coating.Do not disperse if particle is not ground before the coating, just might be to the coating of aggregate particles or flocculation particle, this coating thing is pulverized once steam flow, coating layer is broken, what present is a kind of incomplete coating state, do not reach the intended purposes of surface treatment or coating, therefore the wetting grinding of the pigment particles of preceding pulverizing must be disperseed.
Calcining kiln blanking before the titanium dioxide surface treatment must be through realizing after preceding pulverizing and the abundant wetting grinding dispersion as can be seen from above-mentioned narration, and domestic most of titanium white production producer adopts roll-in mill+online dispersion machine+sand mill to realize usually, pigment particles fineness 85%＜45 μ m after online dispersion machine disperses, pigment particles fineness 99%＜45 μ m behind sand mill.Because have 1% coarse granule, these coarse granules to be enough to make to film greater than 45 μ m, the plastic material surface produces flaw and striped, and influence glossiness, covering power and the tinting strength, tinting power of filming will produce the application performance of titanium white powder pigment and have a strong impact on.
The utility model content
The purpose of this utility model provide a kind of can be with sand milling slip fineness 100%＜45 μ m of kiln blanking after preceding pulverizing and wetting dispersion, make the pigment particles surface can obtain abundant coating and handle, improve a kind of preceding equipment of pulverizing of titanium white sulfuric acid method titanium pigment device calcining kiln blanking that is used for of titanium white powder pigment quality greatly.
In order to achieve the above object, the utility model is to adopt following structure:
A kind of preceding equipment of pulverizing of titanium white sulfuric acid method titanium pigment device calcining kiln blanking that is used for, comprise roll-in mill, slip storage tank, charging pump and sand mill, described roll-in mill, slip storage tank, charging pump and sand mill connect successively, between described roll-in mill and slip storage tank, be connected with wetting groove and ceramic ball mill in turn, the import of described wetting groove is connected in the outlet of described roll-in mill, and the discharging opening of wetting groove is connected on the charging aperture of described ceramic ball mill.
Pulverize mixing channel, impeller pump, the online dispersion machine that uses before adopting said structure to substitute in the existing sulfuric acid method titanium pigment device production process, use wetting groove and ceramic ball mill (3) to realize roll-in mill back material dispersed and grinding and prior art can only realize peptizaiton again with wetting groove and ceramic ball mill.And ceramic ball mill can possess dispersion simultaneously and grind function.This equipment can make sand milling slip fineness 100%＜45 μ m, average particle size distribution is between 0.28～0.38 μ m, product quality is improved greatly, product grind dispersity (the graceful number of black square) is brought up to more than 6.5 by 6.0, product covering power (Reynolds now count) is brought up to more than 2000 by 1950, and product whiteness, oil absorption all than before product make moderate progress.
In the described wetting groove wetting agent is housed.
Beneficial effect is: the utility model can make sand milling slip fineness 100%＜45 μ m of kiln blanking after preceding pulverizing and wetting dispersion the pigment particles surface can obtain abundant coating and handle, and improves the titanium white powder pigment quality greatly.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the existing equipment structural representation;
Wherein among Fig. 2: 7 is that mixing channel, 8 is that impeller pump, 9 is online dispersion machine.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
As shown in Figure 1, a kind of preceding equipment of pulverizing of titanium white sulfuric acid method titanium pigment device calcining kiln blanking that is used for, comprise roll-in mill 1, slip storage tank 4, charging pump 5 and sand mill 6, described roll-in mill 1, slip storage tank 4, charging pump 5 and sand mill 6 connect successively, between described roll-in mill 1 and slip storage tank 4, be connected with wetting groove 2 and ceramic ball mill 3 in turn, the import of described wetting groove 2 is connected in the outlet of described roll-in mill 1, and the discharging opening of wetting groove 2 is connected on the charging aperture of described ceramic ball mill 3.In the described wetting groove 2 wetting agent is housed.
Operation principle of the present utility model and production technology: the calcining kiln blanking enters wetting groove 2 and mixes with wetting agent after 1 fragmentation is ground in roll-in after, overflow to ceramic ball mill 3 grinds and disperses the laggard slip storage tank 4 of going into, and being delivered to through charging pump 5 becomes the sand milling slip after sand mill grinds again.In addition, under the prerequisite that does not influence sand milling slip fineness, can suitably relax, realize that roll-in mill and ceramic ball mill domesticize fully the requirement of roll-in abrasive particle degree.
