Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a self-supporting structure for the inlet of a flash tank. Background Technology

Traditional flash tank inlet support structures are prone to structural failure under high temperature, high pressure, and corrosive media, leading to high equipment maintenance costs and reduced production efficiency.

[0003] Therefore, a novel self-supporting structure is needed to improve the stability and corrosion resistance of flash tanks in order to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that traditional flash tank inlet support structures are prone to structural failure under high temperature, high pressure and corrosive media, resulting in high equipment maintenance costs and reduced production efficiency. Therefore, a self-supporting structure for flash tank inlets is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A downward sloping surface is provided at one end of the first brick, the second brick, and the third brick away from the pipe opening. A first trapezoidal brick, a second trapezoidal brick, and a clamping brick are respectively pasted on the sloping surfaces of the first brick, the second brick, and the third brick. The length of the second brick is greater than the first brick and the first trapezoidal brick forming the self-supporting pasting point. The length of the third brick is less than the second brick. A second trapezoidal brick is pasted on the sloping surface of the second brick. The clamping brick corresponds to the second brick and the second trapezoidal brick forming the self-supporting pasting point and is fixed to the sloping surface of the third brick.

[0009] Furthermore, a third trapezoidal brick is pasted on the side of the clamping brick away from the third brick, and the self-supporting pasting point formed by the third brick and the third trapezoidal brick is located at the top of the second trapezoidal brick.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-2 A self-supporting structure for the inlet of a flash tank, comprising:

[0024] Flash tank inlet body 1;

[0025] The self-supporting mechanism includes a pipe opening 2 vertically disposed at the top of the flash tank pipe opening body 1 and a first brick 3 fixed to the outer wall of the pipe opening 2. A second brick 4 and a third brick 5 are sequentially fixed to the outer wall of the pipe opening 2 from bottom to top on the first brick 3. A downward-sloping surface 301 is provided at one end of each of the first brick 3, second brick 4, and third brick 5 along the length direction away from the pipe opening 2. A first trapezoidal brick 302 and a second trapezoidal brick 40 are respectively attached to the slope surface 301 of the first brick 3, second brick 4, and third brick 5. 1. The second brick 4 is longer than the self-supporting adhesive joint formed by the first brick 3 and the first trapezoidal brick 302. The third brick 5 is shorter than the second brick 4. The second trapezoidal brick 401 is pasted on the sloping surface 301 of the second brick 4. The clamping brick 501 corresponds to the self-supporting adhesive joint formed by the second brick 4 and the second trapezoidal brick and is fixed on the sloping surface 301 of the third brick 5. Due to the special design of the sloping surface 301 and the mutual locking mechanism, the self-supporting structure can still remain stable and will not collapse or deform.

[0026] In this application, a third trapezoidal brick 502 is attached to the side of the clamping brick 501 away from the third brick 5, and the third brick 5 and the third trapezoidal brick 502 form a self-supporting attachment point located at the top of the second trapezoidal brick 401.

[0027] In this application, the bottom area of ​​the clamping brick 501 is greater than the top area of ​​the clamping brick 501, and the size of the clamping brick 501 is one-third of the size of the third brick 5.

[0028] In this application, the first brick 3, the second brick 4, the third brick 5, the first trapezoidal brick 302, the second trapezoidal brick 401, the third trapezoidal brick 502 and the sandwich brick 501 are all made of corrosion-resistant and high-temperature resistant silicon carbide material. The design between the bricks ensures that the bricks can lock together to form self-support without external mortar.

[0029] The implementation principle of a flash tank nozzle self-supporting structure in this application embodiment is as follows: Refractory materials with excellent corrosion resistance, such as silicon carbide bricks, silica bricks, and high-alumina bricks, are selected as the brick materials for the nozzle self-supporting structure. First brick 3, second brick 4, and third brick 5 are sequentially installed on the outer wall of the nozzle 2. Then, first trapezoidal brick 302, second trapezoidal brick 401, and clamping brick 501 are respectively adhered to the sloping surfaces 301 of the first brick 3, second brick 4, and third brick 5 using adhesive. When the adhesive is washed away, the sloping surface 301 of the second brick 4 matches the inclination angle of the second trapezoidal brick 401, automatically aligning and locking under gravity. The bottom area of ​​the clamping brick 501 is larger than its top area, embedding between the third brick 5 and the second trapezoidal brick 401. A wedge-shaped structure fills the gaps, enhancing lateral stability. The contact surface between the bricks is a rough surface (such as silicon carbide bricks, silica bricks, and high-alumina bricks). The natural texture of silicon material generates sufficient friction under gravity to prevent relative sliding. The inclined angle design of the trapezoidal bricks decomposes the gravity into vertical pressure and horizontal locking force, further consolidating the structure. The decreasing size design of the first brick 3, the second brick 4, and the third brick 5 ensures that the pressure of the upper bricks is evenly transferred to the lower layer, avoiding local overload. Each layer of bricks forms a "cantilever beam" effect through the inclined surface 301 of the trapezoidal bricks, distributing the load to multiple support points. The inclined angle of the trapezoidal bricks converts part of the gravity into lateral locking force, enhancing shear resistance. The first brick 3 bears the top load of the pipe opening and transfers the pressure to the second brick 4 through the first trapezoidal brick 302. The second brick 4 distributes the load to the third brick 5 and the clamping brick 501 through the second trapezoidal brick 401, and finally, it is evenly borne by the bottom first brick 3 and the first trapezoidal brick 302.

[0030] All structures in this application can be customized in terms of material and length according to actual usage. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted accordingly.

[0031] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
