Technical Field
The utility model relates to a petrochemical technical field especially relates to anticorrosive pouring frock of tube sheet.
Background
The corrosion prevention technology in chemical equipment is diversified, for example, rubber lining in the equipment, special titanium lining in the equipment, special zirconium lining, special nickel lining in the equipment, lead lining in the equipment and the like are required, the sulfur condenser requires that light materials (mainly comprising ceramic particles, perlite, additives and the like) are poured on the surface of a tube plate, the pouring thickness is 10mm, the pouring material is easy to fall into a heat exchange tube in the pouring process at present, and a pouring body is easy to damage when the pouring tool is detached, so that the tube plate corrosion prevention pouring tool is provided.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing an anti-corrosion pouring tool for a tube plate.
In order to realize the purpose, the utility model adopts the following technical scheme:
the design tube sheet anticorrosion pouring tool comprises a tube sheet, wherein a heat exchange tube penetrates through the middle of the tube sheet, a plug is inserted into the top end of the heat exchange tube, a cofferdam is installed at the top end of the tube sheet, a bolt and nut fastening assembly is installed between the cofferdam and the tube sheet, a pouring light material located at the center of the cofferdam is installed at the top end of the tube sheet, and the thickness of the pouring light material is 10mm.
Preferably, the top end of the plug is of a tetragonal structure, the bottom end of the plug is of a cone structure, and the cone structure is located inside the heat exchange tube.
Preferably, the surfaces of the plugs and the cofferdam are provided with plastic sealing layers.
Preferably, the inner diameter of the cofferdam is the same as the outer diameter of the poured light material, and the outer diameter of the cofferdam is the same as the outer diameter of the tube plate.
The utility model provides an anticorrosive pouring frock of tube sheet, beneficial effect lies in: the utility model discloses can pour accurately and pour the light material, prevent to pour simultaneously that the light material gets into the heat exchange tube, also can make things convenient for the dismouting frock to prevent to cause the damage to pouring the light material, simple structure, convenient to use is reliable, and the security is higher.
Drawings
Fig. 1 is a schematic structural view of a tube sheet anti-corrosion pouring tool provided by the utility model;
fig. 2 is the utility model provides a pouring structure schematic diagram after frock is demolishd to anticorrosive pouring frock of tube sheet.
In the figure: the device comprises a plug 1, a pouring light material 2, a heat exchange tube 3, a tube plate 4, a bolt and nut fastening assembly 5 and a cofferdam 6.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, the tube plate anticorrosion pouring tool comprises a tube plate 4, a heat exchange tube 3 penetrates through the middle of the tube plate 4, a plug 1 is inserted into the top end of the heat exchange tube 3, a cofferdam 6 is installed at the top end of the tube plate 4, a bolt and nut fastening assembly 5 is installed between the cofferdam 6 and the tube plate 4, the tube plate 4 and the cofferdam 6 are fixedly connected through the bolt and nut fastening assembly 5, a pouring light material 2 located in the center of the cofferdam 6 is installed at the top end of the tube plate 4, and the thickness of the pouring light material 2 is 10mm.
The top end of the plug 1 is of a tetragonal structure, the bottom end of the plug 1 is of a conical structure, the conical structure is located inside the heat exchange tube 3, the plug 1 is used for preventing casting materials from falling into the heat exchange tube 3, and when the plug 1 is dismounted, the end of the plug 1 can be slightly rotated by clamping a spanner, and then the plug 1 is dismounted.
The surfaces of the plug 1 and the cofferdam 6 are both provided with plastic sealing layers, in order to prevent the pouring of the light material 2 from being combined with the plug 1 and the cofferdam 6 together, so that the pouring body is damaged when the tool is dismounted, the surfaces of the cofferdam 6 and the plug 1 are subjected to plastic sealing, and the tool and the pouring light material 2 are isolated by using a plastic sealing material.
The inner diameter of the cofferdam 6 is the same as the outer diameter of the poured light material 2, the outer diameter of the cofferdam 6 is the same as the outer diameter of the tube plate 4, and the pouring quality can be guaranteed.
After pouring is finished, the plastic package materials on the surfaces of the cofferdam 6 and the plug 1 are partially cut by an art designer after drying, the plastic package materials are conveniently separated from the tooling when the tooling is disassembled, the plastic package materials remained on the surface of the pouring light material 2 can be dissolved when the pouring light material 2 is baked, and few impurities remained on the surface of the pouring light material 2 are removed by slight polishing after baking.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
