[0041] A design method of a solid bin capable of optimizing discharging efficiency, comprising:

[0042] S1, establishing a basic model of a solid bin in a finite element software; the basic model comprises a straight cylinder section and a closing section located below the straight cylinder section; the inner diameter of the closing section continuously decreases along the direction of the downward movement of the material; the closing section is composed of a conical shell 2 and two inclined flat plates 5, the two inclined flat plates 5 are located on the two sides of a vertical plane, and preferably are symmetrically arranged on the two sides of the vertical plane; the two sides of the two inclined flat plates are connected by a circular arc-shaped conical shell respectively, and the two circular arc-shaped conical shells and the two inclined flat plates 5 enclose a channel of the closing section;

[0043] S2, designing the outlet size of the basic model and the inclination of the inclined flat plate according to the properties of the material and the operation needs;

[0044] S3, first reinforcing the conical shell and the inclined flat plate by using a profile steel; then performing mesh division on the basic model, and then setting boundary conditions and loads of the finite element model; finally, performing deformation analysis and stress analysis on the reinforced basic model by using a finite element analysis method, and optimizing the position and specification of the profile steel according to the results of the deformation analysis and the stress analysis;

[0045] S4, obtaining the position where the deformation of the inclined flat plate is large by finite element calculation, and using a tensile support to control the deformation at the position.

[0046] The boundary conditions include but are not limited to: the axial constraint condition of the end face of the cylinder or the large end section of the conical shell, the symmetric constraint condition of the model symmetric surface, the connection contact condition of the profile steel and the inclined flat plate and the conical shell, and the like.

[0047] The loads include but are not limited to: the pressure load in the bin, the static pressure load of the material, the gravity load, the circumferential force load of the small end section of the conical shell, and the like.

[0048] When performing the finite element analysis, the maximum stress of each part of the solid bin is extracted respectively, and compared with the corresponding allowable stress value.

[0049] If the maximum stress at each place is less than the corresponding allowable stress, the structural strength is qualified; optimization is carried out by the following method: reducing the thickness of the straight cylinder section, the conical shell and the inclined flat plate, reducing the size of the section steel, increasing the spacing of the reinforcing section steel and the like to optimize the design;

[0050] If the maximum stress at any place is not less than the corresponding allowable stress, the structural strength is unqualified; adjustment is carried out by the following method: increasing the thickness of the conical shell and the inclined flat plate, increasing the size of the section steel, reducing the spacing of the reinforcing section steel and the like to adjust, and then re-performing finite element analysis.

[0051] When the structural strength is qualified, the deformation result of the structure in the finite element calculation result is extracted, the internal bracing is arranged at the place where the deformation of the inclined flat plate is the largest, and the external section steel ring is arranged at the place where the deformation of the conical shell is the largest.

[0052] The utility model adopts finite element analysis method, aiming at the conical shell position, inclined flat plate position and reinforcing section steel structure of solid bunker capable of improving discharging efficiency, carries out detailed deformation analysis and stress analysis, aims at optimizing the layout and selection of section steel, to ensure the safety of structure. In the area where the deformation of the inclined flat plate position is more remarkable, the utility model adopts the bracing structure to effectively control the deformation, so as to ensure that the bunker can maintain the integrity and beauty of its form in the use process.

[0053] In the finite element analysis software, the conical shell of the solid bunker and its connected cylinder, inclined flat plate and reinforcing section steel structure need to be constructed, and fine mesh division is carried out. Then, the boundary conditions and load of the finite element model need to be set.

[0055] In the initial stage of finite element analysis, the structural parameters of the model can be determined according to the theoretical calculation method in the relevant standard. After optimizing and adjusting the structure according to the results of finite element analysis, finite element analysis needs to be carried out again, and the structural optimization design needs to be carried out, until the maximum optimization of the silo shell thickness and the steel weight is realized under the premise of ensuring safety, so as to reduce the equipment investment, and at the same time ensure the integrity and aesthetics of the shape of the silo during use.

The design temperature of the silo is 100℃, the design pressure is normal pressure, and the material density is 960-1060 Kg / m 3 After the thickness of the conical shell and the connected cylinder (length of 2 m), the thickness of the inclined flat plate and the size of the steel are preliminarily determined, a finite element model is established in ANSYS software, considering the symmetry of the model structure, therefore 1 / 2 model is established.

According to the preliminary analysis result, the maximum stress of each part of the shell is less than the corresponding allowable stress, and the maximum tensile stress and the maximum tensile-bending combined stress of the reinforcing section steel are also less than the allowable stress of the material, so the structure optimization design is carried out by considering reducing the specification of the reinforcing section steel and increasing the spacing of the reinforcing section steel. The maximum deformation of the inclined flat plate appears at the center position of the flat plate, and the maximum deformation of the conical shell appears at the position close to the lower end of the conical shell, so the inner tensile brace is arranged at the maximum deformation position of the inclined flat plate, six steel pipes are used for the tensile brace, and the reinforcing section steel ring is arranged outside the conical shell, and the specification of the section steel is the same as that of the reinforcing section steel of the inclined flat plate, so as to reduce the deformation and keep the silo complete and beautiful in shape during use.
