Abstract
The utility model discloses a sealing device of a rotary kiln for titanium dioxide. The sealing device comprises more than two sealing blocks, wherein each sealing block covers the outer side wall of a kiln body, a steel wire rope winds the outer side of a sealing ring which is formed by the sealing blocks and tightly contacted with the outer side wall of the kiln body, the two ends of the steel wire rope respectively penetrate through a fixed pulley fixed on the kiln body, and weights are respectively hung at the two ends of the steel wire rope. The sealing device has the beneficial effects that a circle of sealing ring is installed on the outer side wall of the kiln body of the conventional rotary kiln for the titanium dioxide and is fully and tightly contacted with the kiln body through the steel wire rope winding the outer side of the sealing ring as well as the weights, so that the rotary kiln is sealed, the evaporating, emitting, dripping and leaking of raw materials are relieved, a production environment is improved, the product loss is reduced, and the production cost is lowered.
Description
Technical field
The utility model relates to a kind of white titanium pigment seal of rotary kiln device, is applicable to the titanium white production technical field.
Background technology
White titanium pigment is a kind of fine white pigment, has excellent physics, chemistry, optics and pigment performance.In industrial production such as coating, plastics, papermaking, rubber, chemical fibre, be widely used.In recent years, titanium white production producer increased gradually, and production capacity enlarges gradually, but the production efficiency and the quality product of most of titanium white production producer also rest on original degree, did not improve effectively.In order in market competition, to be on a good wicket; Must be in quality product; Such as improving on the key technical index such as the form and aspect of white titanium pigment, whiteness, reducing power; These technical indicators of white titanium pigment depend on the burning quality in the production process to a great extent, and calcination process is in rotary kiln, to carry out.The rotary kiln principle of work is following: titanium oxide hydrolyzate filter cake input that at first will be after filtering has constant slope and slow rotating white titanium pigment rotary kiln body tail end (cylindrical shell high-end), and the burning mixing section of kiln hood direction (low side of cylindrical shell) is blown into the flame of cleaning and hot blast in the kiln filter cake is dewatered, calcines simultaneously.Hydrolyzed titanium dioxide filter cake after high temperature dewaters, calcines more than 1000 ℃ is by the white titanium pigment rotary kiln body that tilts, when along the circumferential direction rolling vertically (from high-end to low side) move, constantly accomplish dehydration and incinerating technological process.Final biliquid pressure plate discharge valve through kiln hood cover bottom gets into cooler, and the material after cooling, screening is the white titanium pigment finished product.What original seal of rotary kiln adopted is packing seal, and owing to congenital reason, the face runout amount and the ovality of rotary kiln are bigger; Adopt the packing seal poor; The spillage of white titanium pigment is bigger, and on average every day, spillage reached 50 kg～100kg, serious environment pollution; Product loss is big, and production cost is high.Therefore press for Sealing of Rotary Kiln is improved, improve burning quality, reduce production costs.
The utility model content
The utility model technical problem to be solved provides a kind of white titanium pigment seal of rotary kiln device, realizes Sealing of Rotary Kiln has effectively been reduced the raw material evaporating, emitting, dripping or leaking of liquid or gas, has improved production environment, has reduced product loss, has reduced production cost.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of white titanium pigment seal of rotary kiln device, comprise the sealing block more than two, and said each sealing block all covers on the outer side wall of kiln body; Outer felt at the wear ring that closely contacts with the external sidewall of kiln that is formed by each sealing block is wound with wireline; The fixed pulley that is fixed on the kiln body is passed at the two ends of wireline respectively, is hung with weight respectively in two ends of wireline.
Said sealing block is an ingot pig, and its quantity is 24.
Above-mentioned each piece sealing block fully contacts with each section circular arc of kiln body; Formation is around a circle wear ring of the external sidewall of kiln; The wireline two ends that are wrapped on the wear ring are strained by weight, guarantee that the trim of wear ring closely contacts Sealing of Rotary Kiln with the kiln body, in the production process; During rotary kiln running, the sealing device can effectively be avoided the leakage of material.
Adopt the beneficial effect that technique scheme produced to be: the utility model is through having installed a circle wear ring on the external sidewall of the kiln of original white titanium pigment rotary kiln; And wear ring is fully closely contacted with the kiln body through the wireline cheek weight that is wrapped in the wear ring outside; Be implemented in Sealing of Rotary Kiln, reduced the raw material evaporating, emitting, dripping or leaking of liquid or gas, improved production environment; Reduce product loss, reduced production cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model;
Wherein, 1, the kiln body, 2, sealing block, 3, fixed pulley, 4, wireline, 5, weight.
Embodiment
Embodiment as shown in Figure 1 can know that the described white titanium pigment seal of rotary kiln of the utility model device comprises 24 sealing blocks 2, and said each sealing block 2 all covers on the outer side wall of kiln body 1; Outer felt by each sealing block 2 wear ring that closely contacts with kiln body 1 outer side wall that form is wound with wireline 4; The fixed pulley 3 that is fixed on the kiln body 1 is passed at the two ends of wireline 4 respectively, is hung with weight 5 respectively in two ends of wireline 4.Said sealing block 2 is that cast iron is fast.
Above-mentioned each piece sealing block 2 fully contacts with each section circular arc of kiln body 1; Formation is around a circle wear ring of kiln body 1 outer side wall; Wireline 4 two ends that are wrapped on the wear ring are strained by weight 5, guarantee that the trim of wear ring closely contacts Sealing of Rotary Kiln with kiln body 1, in the production process; During rotary kiln running, the sealing device can effectively be avoided the leakage of material.
Claims (2)
