Abstract
The utility model discloses an anti-corrosion sheath of a pipe opening short pipe of a storage device for acid corrosive media. The anti-corrosion sheath comprises a cylinder, a first baffle and a second baffle, wherein the first baffle is fixed to the outer wall of one end of the cylinder, the second baffle is fixed to the outer wall of the other end of the cylinder, and furan cement gum is filled between the outer wall of the cylinder and the inner wall of the pipe opening short pipe. The anti-corrosion sheath is installed on the position between a material opening short pipe and a manhole short pipe of the storage device containing the acid corrosive media, corrosion and scouring of the corrosive media for rubber lining plate anti-corrosion layers on the short pipes can be isolated, corrosion to the body of the storage device after ageing, cracking and damage to the rubber lining plate is prevented, the service life of the storage device is prolonged, and smooth operation of production is guaranteed.
Description
Technical field
The utility model relates to a kind of Korrosionsmedium storage device anticorrosion technique field, specifically a kind of storage device mouth of pipe short tube anticorrosion sheath of acidic corrosive media.
Background technique
The storage device inner wall anti-corrosive layer of producing for phosphoric acid, phosphorus ammonium, the general carbon steel lining acid-resistant rubber sheet that adopts is made, the mouth of pipe short tube of storage device is because severe corrosive, the flow of fluid of phosphoric acid washes away and the impact of medium temperature etc., the easy season cracking of corrosion protection line with rubber plate, a bag, acid solution are washed away rear cracky, cause the corrosion to storage device body.
Model utility content
The purpose of this utility model is to provide a kind of acid medium storage device mouth of pipe short tube anticorrosion sheath, with solve strong acid medium storage device mouth of pipe short tube corrosion protection line with rubber plate season cracking, wash away the problem that causes the corrosion of storage device body after breakage.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is as follows:
A kind of acid medium storage device mouth of pipe short tube anticorrosion sheath, it comprises cylindrical shell, the first baffle plate, second baffle, described the first baffle plate is fixed on one end outer wall of described cylindrical shell, on the other end outer wall of described cylindrical shell, be fixed with described second baffle, between the inwall of the outer wall of described cylindrical shell and mouth of pipe short tube, be filled with furan mastic, the external diameter of described cylindrical shell is than the little 10-15mm of the internal diameter of described mouth of pipe short tube, the long 20-30mm of length of mouth of pipe short tube described in the Length Ratio of described cylindrical shell.
As further improvement of the utility model, described the first baffle plate is identical with the shape of described second baffle, equal and opposite in direction.
The beneficial effects of the utility model are: the utility model is installed to the storage device mouth of pipe short tube place that is loaded with highly acid aggressive medium, can intercept tool Korrosionsmedium to the corrosion of short tube place line with rubber plate corrosion-resistant coating and wash away, prevent the corrosion to storage device body after line with rubber plate season cracking, breakage, extend the working life of storage device, guarantee carrying out smoothly of production.

Embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
A kind of acid medium storage device mouth of pipe short tube anticorrosion sheath as shown in Figure 1 and Figure 2, it comprises cylindrical shell 6, the first baffle plate 4, second baffle 8, the first baffle plate 4 is fixed on one end outer wall of cylindrical shell 6, on the other end outer wall of cylindrical shell 6, be fixed with second baffle 8, between the inwall of the outer wall of cylindrical shell 6 and mouth of pipe short tube 11, be filled with furan mastic 9, the external diameter of cylindrical shell 6 is than the little 10-15mm of the internal diameter of mouth of pipe short tube 11, the long 20-30mm of length of the Length Ratio mouth of pipe short tube 11 of cylindrical shell 6.
The first baffle plate 4 is identical with the shape of second baffle 8, equal and opposite in direction.
When mouth of pipe short tube anticorrosion sheath is installed, the first baffle plate 4 is welded to one end of cylindrical shell 6, requires full weld and weld seam full; On the sealing surface of tank body pipe connecting flange 1, place an acid-resisting rubber sealing gasket 5; Cylindrical shell 6 is inserted to inwall and be evenly coated with in the short tube 11 of furan mastic 9, with 6 installation pressing plates 2, put on bolt 3, the first baffle plate 4, sealing gasket 5, storage device pipe connecting flange 1 are tightly forced together, cylindrical shell 6 is positioned; Gap between cylindrical shell 6 outer walls and short tube 11 inwalls is filled tight with furan mastic 9; Second baffle 8 is welded on to cylindrical shell 6 and stretches into the other end in storage device, require full weld and weld seam 7 full; In gap between second baffle 8 and inner tank wall acid-proof lining offset plate 10, also fill furan mastic 9; After furan mastic 9 solidifies, remove pressing plate 2 and bolt 3 are installed, storage device can come into operation.
Above-described is only preferred embodiment of the present utility model, does not limit to the utility model.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the utility model, can also make other equivalent modifications and improvement, all can realize the purpose of this utility model, all should be considered as protection domain of the present utility model.
