[0022] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0023] The utility model provides a vibrating screen box, such as Figure 2-3As shown, a vibrating screen box of an embodiment includes a first screening assembly 11, a first side plate 12 and a second side plate 13. The first side plate 12 and the second side plate 13 are arranged in parallel and spaced apart, and the first screening assembly 11 is located between the first side plate 12 and the second side plate 13 and is fixedly connected to the first side plate 12 and the second side plate 13. The first screening assembly 11 includes a first connecting member 111, a first folding plate 112, a second folding plate 113 and a screen (not shown in the figure), and the two ends of the first connecting member 111 are respectively welded to the first folding plate 112 and the second folding plate 113, and the first connecting member 111, the first folding plate 112 and the second folding plate 113 are relatively fixed, and the first screening assembly 11 is an integral welded member. The first folding plate 112 is detachably connected to the first side plate 12 by a fastener, and the second folding plate 113 is detachably connected to the second side plate 13 by a fastener. The screen is relatively fixedly connected to the first connecting member 111 for screening materials.
[0024] In the vibrating screen box of the utility model, the first connecting piece 111, the first folding plate 112 and the second folding plate 113 of the first screening component 11 are designed to be welded as a whole, which improves the stability of the vibrating screen box structure, improves the seismic performance, extends the service life, and reduces the subsequent maintenance cost; the whole after welding is connected to the first side plate and the second side plate respectively through the first folding plate and the second folding plate, which greatly reduces the manufacturing and assembly precision, ensures the seismic performance of the whole machine, and can transmit the vibration force more evenly.
[0025] In this embodiment, please combine Figure 4 For reference, the first folding plate 112 and the second folding plate 113 are plate-like components made of metal or other materials, which are formed into a curved structure after being bent. Folding plates are usually used for structural support, connection or fixation, which can increase the strength and stability of the components. After bending, a more solid and stable structure is formed, which can effectively support and fix the first screening component 11 and enhance the overall structural stability. The bent first folding plate 112 and the second folding plate 113 have better load-bearing capacity and compressive resistance, which can increase the overall structural strength of the first screening component 11 and improve the durability and stability of the vibrating screen equipment. The first folding plate 112 and the second folding plate 113 are made by bending the whole material, such as Figure 5 As shown, the structure in this embodiment only needs to ensure the assembly accuracy of the first folding plate 112 and the second folding plate 113. The first folding plate 112 and the second folding plate 113 are welded to the hole of the first connecting member 111 to form an integral welded member, which reduces the requirements for the processing accuracy of the first connecting member 111. Compared with the existing screen box structure in which the crossbeam is detachably connected to the side plate by fasteners, it is necessary to ensure the accuracy of the connection between each crossbeam and the side plate to ensure the anti-seismic performance of the entire vibrating screen. Low accuracy will make the connection between the crossbeam and the side plate of the vibrating screen easy to loosen during the vibration process, and will also cause certain obstacles or unevenness in the transmission of vibration force.
[0026] In this embodiment, the first connecting member 111 can be a cylindrical steel pipe, specifically a seamless steel pipe. A seamless steel pipe is a steel pipe made by punching a whole round steel bar without a weld on the surface. The first connecting member 111 is the main structure of the first screening component 11. The use of a seamless steel pipe is conducive to the passage of materials. When the materials pass through the first connecting member 111, they fall along the outer surface due to its cylindrical structure, and will not cause material blockage.
[0027] In this embodiment, the first screening assembly 11 further includes a first rib plate 114, the length direction of the first rib plate 114 is perpendicular to the length direction of the first connecting member 111, and the first rib plate 114 is fixedly connected to the first connecting member 111. The first rib plate 114 is used to enhance the overall structural stability and strength of the first screening assembly 11.
[0028] In a preferred embodiment, there are multiple first connectors 111, multiple first ribs 114, multiple first connectors 111 are spaced apart along the length direction of the first ribs 114, multiple first ribs 114 are spaced apart along the length direction of the first connector 111, and the first connectors 111 and the first ribs 114 are connected to each other in a grid shape. Specifically, 7 first connectors 111 and 6 first ribs 114 are selected in this embodiment. Of course, those skilled in the art can set the number of first connectors 111 to 4, 5, 6, 8, 9, 10, etc. according to actual conditions, and this is not a sole limitation; those skilled in the art can set the number of first ribs 114 to 4, 5, 7, 8, 9, 10, etc. according to actual conditions, and this is not a sole limitation.
[0029] In the present embodiment, the first screening assembly 11 further comprises a first mounting member 115, the length direction of the first mounting member 115 is perpendicular to the length direction of the first connecting member 111, and the first mounting member 115 is fixedly connected to the first connecting member 111 for fixing and installing the screen. The screen is used to filter, screen or separate solid particles in the material. Specifically, a plurality of mounting points are provided on the first mounting member 115, and the plurality of mounting points are spaced apart along the length direction of the first mounting member 115, and each mounting point is fixedly connected to the screen to complete the installation of the screen. In the present embodiment, there may be two first mounting members 115, and the two mounting members 115 are spaced apart along the length direction of the first connecting member 111. Of course, those skilled in the art may set the number of the first mounting members 115 to 1, 3, 4, 5, etc. according to the actual situation, and no unique limitation is made here.
[0030] In this embodiment, the first screening assembly 11 further includes a first baffle 116 and a first discharge plate 117. The first baffle 116 and the first discharge plate 117 are respectively located at the two ends of the first rib 114. The first baffle 116 is used to support and fix one end of the first screening assembly 11, and the first baffle 116 is fixedly connected to the first folding plate 112, the second folding plate 113 and the first rib 114. The first discharge plate 117 is located at one end of the first rib 114 away from the first baffle 116, and is fixedly connected to the first folding plate 112, the second folding plate 113 and the first rib 114. The first connecting member 111 is located between the first baffle 116 and the first discharge plate 117. The function of the first discharge plate 117 is to control the discharge direction and flow of the material, ensure that the material flows out of the equipment smoothly, avoid accumulation or overflow, and thus maintain a smooth and efficient production process. When performing screening work, the discharge hopper is welded to the first discharge plate 117 to merge it into one of the welded parts of the first screening assembly 11, which solves the problems of the discharge hopper being easy to loosen and having large deformation, and can ensure a more stable and strong connection, so that the vibrating screen can better withstand the vibration force and material load during the vibration process, reducing the risk of loosening and deformation.
[0031] In another preferred embodiment, the first screening assembly 11 further includes a second rib plate 118, the two ends of which are respectively fixedly connected to the first folded plate 112 and the second folded plate 113, and the length direction of the second rib plate 118 intersects with the length direction of the first connecting member 111 and forms a first angle. Specifically, there are two second rib plates 118, and the two second rib plates 118 are cross-connected to each other at a certain angle, which can further enhance the structural stability and strength of the first screening assembly 11 and form an oblique rib plate.
[0032] It should be noted that, in this embodiment, the fixed connection between the components in the first screening component 11 can be a welding connection, which is formed by integral welding, that is, the first rib plate 114 is welded to the first connecting member 111, the first mounting member 115 is welded to the first connecting member 111, the first baffle plate 116 is welded to the first folding plate 112, the second folding plate 113 and the first rib plate 114, and the first discharge plate 117 is welded to the first folding plate 112, the second folding plate 113 and the first rib plate 114. Compared with the detachable connection between multiple beams and side plates in the prior art, the processing and assembly precision requirements are higher. The integral welding of the first screening component 11 increases the stability of the vibration screen body 10, enhances the overall seismic resistance and structural strength of the vibration screen, thereby increasing the service life of the vibration screen, making the transmission of vibration force more uniform, reducing the cost of later maintenance and repair, improving the actual production work efficiency, and achieving sustainable development requirements.
[0033] In this embodiment, the vibrating screen box includes two first screening assemblies 11, both of which are located between the first side plate 12 and the second side plate 13 and fixedly connected to the first side plate 12 and the second side plate 13, and the two first screening assemblies 11 are distributed in parallel and spaced apart between the first side plate 12 and the second side plate 13. The first screening assembly 11 located above is used to screen the material, and the first screening assembly 11 located below is used to screen the material falling from the first screening assembly 11.
[0034] It should be noted that the mesh sizes of the screens in the two first screening components 11 are different. The mesh size of the screen of the upper first screening component 11 is larger than the mesh size of the screen of the lower first screening component 11. During the screening process, the material is first screened through the screen in the upper first screening component 11, and the material filtered out in the upper first screening component 11 enters the lower first screening component 11 and is screened again through the screen.
[0035] In this embodiment, the vibrating screen box also includes a third baffle 15, which is fixedly connected to the first side plate 12 and the second side plate 13, and encloses the two first screening components 11, the first side plate 12 and the second side plate 13 to form a material dropping space. The third baffle 15 is used to prevent material from falling out of the material dropping space.
[0036] The utility model also provides a vibrating screen, comprising a vibrating driving member and the vibrating screen box as described above. The vibrating driving member acts on the vibrating screen box to drive the vibrating screen box to vibrate, so as to achieve screening of materials.
