Description

Technical Field

[0001] This utility model relates to the field of reaction equipment technology, and in particular to a glass-lined reaction vessel with good heat insulation effect. Background Technology

[0002] A glass-lined reactor is a reaction vessel in which high-silica glass is lined the inner surface of a steel container and then firmly bonded to the metal surface through high-temperature firing. Glass-lined reactors are commonly used in the petrochemical, rubber, pesticide, dye, and pharmaceutical industries to perform processes such as sulfonation, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation, as well as many other processes involving organic dyes and intermediates.

[0003] During the use of glass-lined reaction vessels, it is usually necessary to heat the interior of the vessel. For example, the "glass-lined reaction vessel with in-tank zirconium coil heating" proposed in Chinese utility model publication CN208449289U includes a reaction vessel body, a jacket outside the reaction vessel body, a zirconium coil inside the reaction vessel body, and a packing box at the connection between the inlet and outlet of the zirconium coil and the reaction vessel body, the packing box being located at the opening of the reaction vessel body. Hot liquid is heated through heat exchange via the zirconium coil, thereby heating the liquid inside the glass-lined reaction vessel to provide the heating conditions for the reaction.

[0004] However, the glass-lined reaction vessel only has heat insulation on the vessel body, such as by using a jacket, and the overall heat insulation needs to be improved. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a glass-lined reaction vessel with good overall heat insulation performance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a glass-lined reaction vessel, comprising a vessel body, the top of which has a vessel opening; It also includes a can lid, which is placed on the can opening at the top of the can body. The can lid has a closing side facing the can body and an outer side facing away from the can body. A first heat insulation cover is connected to the outside of the can lid. The first heat insulation cover is connected to the outside of the can lid and together with the outside of the can lid, they form a first air insulation layer. The outer side of the tank is connected to a jacket, which forms a third air insulation layer by enclosing the outer side of the tank.

[0007] A further technical solution of this utility model: the opening of the first heat insulation cover is set downward, the top of the first heat insulation cover is located at the top, the edge of the first heat insulation cover is connected to the outside of the can lid, and the top of the first heat insulation cover, the edge of the first heat insulation cover and the outside of the can lid together form the first air heat insulation layer.

[0008] A further technical solution of this utility model: the lid has a mating area corresponding to the edge of the can opening of the can body, and a covering area corresponding to the internal space of the can body; A second heat insulation cover is connected to the lid's closing side. The second heat insulation cover is connected to the coverage area of ​​the lid's closing side, and the second heat insulation cover and the lid's closing side together form a second air insulation layer.

[0010] A further technical solution of this utility model: the edge of the second heat insulation cover is inclined downward and gradually towards the top of the second heat insulation cover; The edge of the second heat insulation cover is set to guide the edge of the tank opening; When the can lid is closed onto the can body, the guiding effect of the edge of the second heat insulation cover and the edge of the can opening causes the mating area on the closed side to be aligned with the edge of the can opening.

[0011] A further technical solution of this utility model: the can lid has a material inlet and a corresponding material inlet flange, and the first heat insulation cover and the second heat insulation cover are used to avoid the corresponding material inlet and the corresponding material inlet flange, or to leave through holes for the corresponding material inlet flange.

[0012] A further technical solution of this utility model: the can lid has a motor shaft through-inlet and a corresponding motor mounting seat. The first heat insulation cover and the second heat insulation cover are used to avoid the corresponding motor shaft through-inlet and the corresponding motor mounting seat, or to leave through holes for the corresponding motor mounting seat.

[0013] Further technical solution of this utility model: The first heat insulation cover and the second heat insulation cover are plastic heat insulation covers made of polypropylene material.

[0014] A further technical solution of this utility model: the gap between the feed port flange and the through hole is sealed by applying adhesive.

[0015] Compared with the prior art, the beneficial effects of this technical solution are: by setting the jacket, a third air insulation layer can be formed on the outside of the tank body; by setting the first insulation cover, a first air insulation layer can be formed on the outside of the tank cover, so that the tank cover can also obtain a good heat insulation effect after the tank body is covered.

[0021] The lid 2 has a closing side facing the can body 1 and an outer side facing away from the can body 1.

[0022] A first heat insulation cover 3 is connected to the outside of the can lid 2. The first heat insulation cover 3 is connected to the outside of the can lid 2 and together with the outside of the can lid 2, they form a first air heat insulation layer 4. By setting the first heat insulation cover 3, the first air heat insulation layer 4 can be formed on the outside of the can lid 2, so that the can lid 2 can provide a better heat insulation effect after the can body 1 is covered.

[0023] In some embodiments, the opening of the first heat insulation cover 3 is oriented downwards, the top 301 of the first heat insulation cover is located above, and the edge 302 of the first heat insulation cover is connected to the outside of the can lid 2, so that the top 301 of the first heat insulation cover, the edge 302 of the first heat insulation cover and the outside of the can lid together form the first air insulation layer 4.

[0025] A second heat insulation cover 5 is connected to the lid side of the can lid 2. The second heat insulation cover 5 is connected to the coverage area of ​​the lid side and together with the lid side of the can lid 2, the second heat insulation cover 5 and the lid side of the can lid 2 form a second air heat insulation layer 6.

[0026] In some embodiments, the opening of the second heat insulation cover 5 is oriented upwards, the top 501 of the second heat insulation cover is located below, and the edge 502 of the second heat insulation cover is connected to the covering area of ​​the can lid 2, so that the top 501 of the second heat insulation cover, the edge 502 of the second heat insulation cover and the can lid 2 together form a second air insulation layer 6.

[0027] In some embodiments, the edge 502 of the second heat insulation cover is inclined downward and gradually towards the top 501 of the second heat insulation cover, that is, inclined downward and towards the center.
