Abstract
The utility model relates to a filtering device and particularly discloses a filtering device applied to titanium dioxide hydrolysis. The filtering device applied to titanium dioxide hydrolysis comprises a filter body, a feed inlet is arranged in the upper side of the filter body, a discharge outlet is arranged in the lower side of the filter body, a filter screen is arranged at the front end of the discharge outlet in the filter body, and the filter screen is vertically arranged in the filter body and perpendicular to the discharge outlet. According to the filtering device applied to titanium dioxide hydrolysis, the filter screen is vertically arranged, residual slag in the filtering device is periodically cleaned, so that the blocking phenomenon of the filter screen can be effectively improved, the overlong stay time of materials in a hydrolysis tank can be avoided, and the quality of titanium dioxide powder can be ensured to a certain extent.
Description
Technical field
The utility model relates to a kind of filter, relates in particular to a kind of filter that is applied in the titanium dioxide hydrolysis process.
Background technology
During the Production By Sulfuric Acid Process titanium white, hydrolysis is the key core technology of Producing Titanium Dioxide.The hydrolysis of titanium white be the titanium sulfate of solubility and titanyl sulfate under the inducing of heating and plus seed, being converted into hydrated titanium dioxide is the process of metatitanic acid.Sulfuric acid content reaches about 25% in the rear material because hydrolysis finishes, temperature is at 110 ℃, corrosivity is very strong, thereby hydrolytic decomposition pot all adopt inner liner rubber after (or lining fiberglass) serve as a contrast again acid-proof ceramic tile, material was cooled to about 50 ℃ by graphite heat exchanger after hydrolysis finished, and put to the metatitanic acid storage tank again, because hydrolytic decomposition pot in use has ceramic tile and peels off, in order to prevent that the graphite heat exchanger tubulation from stopping up, damage the graphite tubulation, before heat exchanger, add filter.
The strainer screen that uses in the titanium dioxide hydrolysis process in the prior art is easier to stop up, thereby causes the hydrolysis blowing time long, and filter screen also easily damages.Moreover material is overstand in hydrolytic decomposition pot, and chemical reaction continue to occur, and also can impact the quality of the titanium dioxide produced.
The utility model content
The purpose of this utility model is, proposes a kind of filter that is applied to titanium dioxide hydrolysis, and it can effectively improve the filter net jam phenomenon, avoids material to stop in hydrolytic decomposition pot long-time.
For achieving the above object, the utility model provides a kind of filter that is applied to titanium dioxide hydrolysis, comprise filter body, described filter body upside is provided with a charging aperture, this filter body downside is provided with a discharging opening, the discharging opening front end is provided with a filter screen in this filter body, and this filter screen vertically is arranged in the filter body and arrange vertical with discharging opening.
In the utility model, described filter body can adopt the RPP material to be made.
Described filter screen adopts the red copper material to be made.
Further, also be provided with stiffened panel around the described filter screen, this filter screen fixes by this stiffened panel and filter body inwall.
The filter that is applied to titanium dioxide hydrolysis of the present utility model, it vertically arranges filter screen, and by regularly the residue in the filter being cleared up, can effectively improve the clogging of filter screen, avoid material overstand in hydrolytic decomposition pot, can guarantee to a certain extent the quality of the titanium dioxide of producing.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the tangent plane structural representation that is applied to a kind of specific embodiment of filter of titanium dioxide hydrolysis of the present utility model;
Fig. 2 is the plan structure schematic diagram that is applied to the filter of titanium dioxide hydrolysis among Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, 2, the utility model provides a kind of filter that is applied to titanium dioxide hydrolysis, it comprises filter body 10, described filter body 10 upsides are provided with a charging aperture 12, these filter body 10 downsides are provided with a discharging opening 14, these filter body 10 interior discharging opening 14 front ends are provided with a filter screen 20, this filter screen 20 vertically be arranged in the filter body 10 and with discharging opening 14 vertical settings.The utility model can directly effectively filter the material by discharging opening 14 by these filter screen 20 vertical settings, thereby avoids the obstruction of filter screen, prevents that filter screen 20 from damaging, and can prolong the service life of filter screen 20 to a certain extent.
As a kind of specific embodiment of the present utility model, described filter body 10 can adopt the RPP material to be made.This RPP material is made as and adds reinforcing agent, stabilizing agent, coupling agent in polypropylene, and employing is through the glass fibre modified polypropylene material of coupling agent treatment, its hardness is high, good rigidly, elastic modelling quantity is high, linear expansion coefficient is little, have the characteristics such as extremely strong acidproof, alkaline-resisting, heatproof, be particularly useful in the titanium dioxide hydrolysis production process.
In the utility model, described filter screen 20 can adopt the red copper material to be made.The filter screen 20 that this red copper is made has good corrosion resistance in atmosphere, seawater and some non-oxidizing acid (hydrochloric acid, dilute sulfuric acid), alkali, salting liquid and multiple organic acid (acetic acid, citric acid), can be widely used in chemical industry.Further, as a kind of preferred embodiment of the present utility model, stiffened panel 22 can also be set around filter screen 20, this filter screen 20 fixes with filter body 10 inwalls by this stiffened panel 22.This stiffened panel 22 is in structural design, by using sinew adding strip (not shown) perpendicular to the panel direction, can improve panel and integrally-built bearing capacity, sinew adding strip and panel can be overall structure, perhaps adopt mode cementing or welding to link together.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
