Abstract
The utility model discloses an alkali-corrosion prevention observation window for alkali evaporators, which comprises an erection fixture, a sight glass gland, a sight glass and a sight glass seat, wherein the sight glass gland, the sight glass and the sight glass seat are sequentially stacked-up along the erection fixture, an alkali-corrosion prevention film is arranged between the sight glass and the sight glass seat, as one side of the sight glass contacting with alkaline liquor is provided with the alkali-corrosion prevention film when in use, the alkaline liquor is effectively separated from the sight glass to avoid corrosion by alkaline liquor. The alkali-corrosion prevention observation window has the advantages of prolonging service life, avoiding frequent overhauling and exchanges, effectively increasing production efficiency, lowering production cost and eliminating potential safety hazards caused by alkaline liquor leakage.
Description
Technical field
The utility model relates to the chemical industry equipment that is used for DYE PRODUCTION, particularly a kind of anti-alkaline etching observation window that is used for alkali evaporator.
Background technology
In the manufacturing of dyestuff, evaporimeter is used to concentrated base is evaporated, and the vaporization chamber of evaporimeter is provided with the observation window that is used to observe situation in the evaporimeter, existing observation window visor adopts the glass manufacturing, during use, high-temperature concentrated alkali causes its frequent breakage to the visor seriously corroded, need often maintenance and replacing, have a strong impact on production efficiency, and caused cost of equipment maintenance to increase, and, visor damages the back alkali liquor leakage takes place easily, also has potential safety hazard.
At above-mentioned deficiency, need existing evaporimeter observation window is improved, its visor is difficult for by caustic corrosion, leak in order to avoid often change, keep in repair and produce, enhance productivity, reduce cost, eliminate safe hidden trouble.
The utility model content
In view of this, the utility model provides a kind of anti-alkaline etching observation window that is used for alkali evaporator, and the visor of this observation window can prevent effectively that high-temperature concentrated alkali from producing corrosion to it, reduce the frequency of its damage, effectively raise production efficiency, reduced production cost, and eliminated potential safety hazard.
The anti-alkaline etching observation window that is used for alkali evaporator of the present utility model comprises installing rack and the visor gland that is cascading along installing rack, visor and visor seat, is provided with anti-alkaline etching film between described visor and the visor seat.
Further, be provided with clamping pad between described anti-alkaline etching film and the visor seat;
Further, described anti-alkaline etching film is a polytetrafluoroethylene membrane.
The beneficial effect of utility model: the anti-alkaline etching observation window that is used for alkali evaporator of the present utility model, comprise installing rack and the visor gland that is cascading along installing rack, visor and visor seat, be provided with anti-alkaline etching film between described visor and the visor seat, during use, because the side that visor contacts with alkali lye is provided with anti-alkaline etching film, effectively alkali lye and visor are separated, make visor avoid the corrosion of alkali lye, prolonged its service life, avoid often overhauling replacing, effectively raise production efficiency, reduced production cost, and eliminated the alkali liquor leakage potential safety hazard.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Fig. 1 is a structural representation of the present utility model, Fig. 2 is the left view of Fig. 1, as shown in the figure: the anti-alkaline etching observation window that is used for alkali evaporator of present embodiment, comprise installing rack 1 and the visor gland 2 that is cascading along installing rack 1, visor 3 and visor seat 4, be provided with anti-alkaline etching film 5 between described visor 3 and the visor seat 4, during use, because the side that visor contacts with alkali lye is provided with anti-alkaline etching film, effectively alkali lye and visor are separated, make visor avoid the corrosion of alkali lye, prolonged its service life, avoided often equipment being safeguarded, effectively raise production efficiency, reduced production cost, and eliminated the alkali liquor leakage potential safety hazard.
In the present embodiment, be provided with clamping pad 6 between described anti-alkaline etching film 5 and the visor seat 4,, cause the alkali lye seepage to enter between anti-alkaline etching film and the visor to contact and cause corrosion with visor in order to avoid to fit in anti-alkaline etching film edge not tight.
In the present embodiment, described anti-alkaline etching film 5 is a polytetrafluoroethylene membrane, and the alkali resistant erosion property of material is good, is easy to obtain, and is cheap.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
