Detailed Description
The present invention will be described in further detail with reference to the drawings and the embodiments, in order to make the objects, technical solutions and advantages of the present invention more apparent. It will be understood that when an element is referred to as being "fixed" to another element, it can be directly on the other element or one or more intervening elements may be present therebetween. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used in this specification includes any and all combinations of one or more of the associated listed items.
The large silo of the invention can be used for homogenization, blending, storage and the like of various powders and granules.
Referring to fig. 1, the large-scale bin 200 of the present invention includes a cylinder 201, a base 203 and a top cover 205, wherein the base 203 and the top cover 205 are respectively fixed at two ends of the cylinder 201, and the cylinder 201, the base 203 and the top cover 205 together enclose a closed space for accommodating materials.
Referring to fig. 2 and 3, the cylinder 201 is formed by fixing a plurality of preforms 100. The preform 100 includes a molding 10, a first flange 30, and a second flange 50. The forming part 10 is formed by bending a sheet metal part into an arc shape through a winch, and a plurality of forming parts 10 can be enclosed into a cylinder shape. The molded part 10 comprises a first side 11, a second side 13, a first end 15 and a second end 17; the first side 11 and the second side 13 are located on opposite sides of the molding member 10; the first end face 15 and the second end face 17 are located at opposite end faces of the molded part 10. The first flange 30 is disposed on the first side 11, and the second flange 50 is disposed on the second side 13. In the embodiment of the present invention, the first flange 30 and the second flange 50 are fixed to the molding member 10 by welding, and the welding can be prefabricated in advance in a factory, thereby shortening the period of manufacturing at a construction site.
In another embodiment, the first flange 30 and the second flange 50 may be integrally formed with the molding member 10, that is, the first flange 30 and the second flange 50 are formed on the first side 11 and the second side 13 of the molding member 10 when the molding member 10 is manufactured.
Referring to fig. 2 and 3, the first end surface 15 is a wedge-shaped surface, and the plane of the first end surface 15 and the axis of the forming member 10 form an included angle a, where the included angle a has a value ranging from 15 ° to 70 °, specifically, may have a value of 15 °, 20 °, 30 °, 40 °, 45 °, 50 °, 60 °, 65 ° or 70 °. The smaller the thickness of the molded part 20, the smaller the value range of the included angle a, and the better the welding strength can be obtained.
Similarly, referring to fig. 2 and 3, the second end surface 17 is a wedge-shaped surface, and the plane of the second end surface 17 forms an included angle B with the axis of the molded part 10, where the included angle B may have a value ranging from 15 ° to 70 °, specifically, may have a value ranging from 15 °, 20 °, 30 °, 40 °, 45 °, 50 °, 60 °, 65 °, or 70 °. The smaller the thickness of the molded part 20, the smaller the value range of the included angle B, and the better the welding strength can be obtained.
When the plane of the first end face 15 is parallel to the plane of the second end face 17, the value of the included angle a is equal to the value of the included angle B.
In this embodiment, the first flange 30 and the second flange 50 are perpendicular to the circular arc shape of the molding 10.
Referring to fig. 1-4, when the bin 200 is to be assembled, the first side 11 of one prefabricated member 100 is abutted against the second side 13 of another prefabricated member 100, so that the first flange 30 is opposite to the second flange 50, and the first flange 30 is fixed to the second flange 50 by bolts (as shown in fig. 4) or rivets (not shown). Similarly, a plurality of preforms 100 are fastened by bolts or rivets to form a cylinder 40, and the joints of adjacent preforms 100 are directly welded into a single body that is difficult to disassemble. The cylinder 40 has an annular convex surface 41 formed at one end and an annular concave surface 43 formed at the other end.
The plurality of cylinders 40 are assembled to form the cylinder 201. Specifically, the annular convex surface 41 of one cylinder 40 is placed against the annular concave surface 43 of the other cylinder 40, so that the annular convex surface 41 of one cylinder 40 is embedded in the annular concave surface 43 of the other cylinder 40, and the two cylinders 40 are fixed by welding at the junction of the inner and outer surfaces of the cylinders 201, respectively. Similarly, a plurality of cylinders 40 are welded until the cylinder 201 required for the silo 200 is completed.
Finally, the silo 200 is formed by securing the top cap 205 to the barrel 201.
According to the bin 200, the first flange 30 and the second flange 50 are arranged to fixedly connect the adjacent forming pieces 20, so that the efficiency and the reliability of enclosing the cylinder 40 are greatly improved, and when welding is performed, the adjacent cylinder 40 is in a fixed state, so that the welding quality is improved, and the quality of the bin 200 is improved. The annular convex surface 41 on one cylinder 40 is abutted against the annular concave surface 43 of the other cylinder 40, and the two cylinders 40 are assembled in a fixed mode by welding, so that the positioning is simple and reliable due to the matching of the annular convex surface 41 and the annular concave surface 43, and the welding quality is improved. The bin 200 of the invention not only improves the efficiency of assembly, but also provides the quality and reliability of the bin 200.
It should be noted that the description of the present invention and the accompanying drawings illustrate preferred embodiments of the present invention, but the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, which are not to be construed as additional limitations of the invention, but are provided for a more thorough understanding of the present invention. The above-described features are further combined with each other to form various embodiments not listed above, and are considered to be the scope of the present invention described in the specification; further, modifications and variations of the present invention may be apparent to those skilled in the art in light of the foregoing teachings, and all such modifications and variations are intended to be included within the scope of this invention as defined in the appended claims.
