Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically to a vibrating screen with a double-layer vibrating screen mesh. Background Technology

[0002] In industries such as mining, building materials, and metallurgy, material screening is an indispensable and crucial step. Its purpose is to separate mixtures of materials with different particle sizes to meet the requirements of subsequent processing or use. Traditional screening equipment mostly uses single-layer vibrating screens, which can achieve basic screening functions, but when faced with complex materials or high-volume demands, problems such as low efficiency and poor grading effects have gradually emerged. Therefore, to solve these problems, double-layer vibrating screens have been developed.

[0003] In the prior art, utility model patent application number CN202021511813.4 discloses a vibrating screen with a double-layer vibrating screen mesh, including a vibrating screen body. A material hopper is welded to one side of the top of the vibrating screen body, and a material inlet is opened at the top of the material hopper. A fixing block is connected to one side of the material inlet, and a fixing button is threaded inside the fixing block. A rotating shaft is installed on one side of the fixing block, and an iron plate is connected to the outer wall of the rotating shaft. A material cover is welded to one side of the iron plate. A fixing column is welded to the inner wall of the vibrating screen body, and a second spring is connected to one side of the fixing column. In this double-layer vibrating screen mesh, the material enters from the material inlet and falls into the upper screen mesh, allowing the material to be screened on the upper screen mesh. The first part of the material is collected from the first outlet by the vibration of the upper screen mesh and its own inclination, while the remaining material is collected from the second outlet through the lower screen mesh. The double-layer vibrating screen mesh effectively separates the materials, making the process fast and convenient, and effectively saving time.

[0004] The aforementioned patent makes it easier for materials to be discharged and collected through the outlet of the vibrating screen by tilting the screen. However, when the vibrating screen is tilted, the material will also remain in a downward state during screening, which may result in the material near the outlet of the vibrating screen not being fully screened before being discharged from the vibrating screen, thereby reducing the screening quality of the material. Utility Model Content

[0005] The purpose of this invention is to provide a vibrating screen with a double-layer vibrating screen, which aims to improve the problem that the existing double-layer vibrating screens cause the material to move down too quickly and the screening to be insufficient due to the inclined setting, thus resulting in a reduction in screening quality.

[0029] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0030] Example 1

[0031] like Figure 1 , Figure 3 and Figure 4As shown, a vibrating screen with a double-layer vibrating screen includes a base 1. From bottom to top, a mounting frame 4, a first filter screen 5, and a second filter screen 7 are sequentially arranged on the base 1. A first support column 2 is provided at one end of the base 1, and a second support column 3 is provided at the other end. Two first support columns 2 are provided at one end of the base 1, and two second support columns 3 are provided at the other end, arranged symmetrically at four corners. One end of the mounting frame 4 is rotatably mounted on the first support column 2, and the other end rests on the second support column 3. An electric telescopic rod 10 is vertically arranged on the base 1 near the second support column 3, with its upper end abutting against the lower end face of the mounting frame 4. It also includes a rotating mounting seat 8. A rotating mounting seat 8 is provided at the upper end of the first support column 2, and a rotating connector 401 is provided at the lower end of the mounting frame 4 corresponding to the position of the rotating mounting seat 8. The mounting frame 4 is rotatably mounted on the corresponding rotating mounting seat 8 via the rotating connector 401. Additionally, a fixing pin 11 is included. A horizontal groove 301 is provided at the upper end of the second support column 3. The end of the mounting frame 4 furthest from the first support column 2 abuts against the groove 301. A first fixing hole 302 is provided on the groove 301, and a second fixing hole 408 is provided on the mounting frame 4 corresponding to the first fixing hole 302. The fixing pin 11 is inserted into both the first fixing hole 302 and the second fixing hole 408. One end of the mounting frame 4 is limited by the first support column 2, and the other end is limited by the fixing pin 11 on the second support column 3, thereby preventing the mounting frame 4 from shaking due to vibrations generated during the screening process. The electric telescopic rod 10 includes a support wheel 1001. The upper end of the electric telescopic rod 10 is rotatably equipped with the support wheel 1001, and the lower end of the mounting frame 4 is provided with a support groove 407 corresponding to the support wheel 1001. The electric telescopic rod 10 abuts against the support groove 407 through the support wheel 1001, and as the electric telescopic rod 10 rises, it lifts the mounting frame 4 along the support groove 407. When the electric telescopic rod 10 is not in operation, there is a certain gap between the support wheel 1001 and the support groove 407, which can avoid the mounting frame 4 from interfering with the electric telescopic rod 10 and affecting the service life of the electric telescopic rod 10. When it is necessary to tilt and lift the mounting frame 4, the electric telescopic rod 10 is raised, and the upper end of the support wheel 1001 slides against the support groove 407, thereby tilting and lifting the mounting frame 4. The support wheel 1001 can move and abut against the mounting frame 4, preventing the electric telescopic rod 10 from getting stuck as the lifting angle of the mounting frame 4 changes.

[0032] like Figure 2 , Figure 4 and Figure 5As shown, a shaped rotating shaft 404 is rotatably mounted on the mounting frame 4. One end of the shaped rotating shaft 404 is connected to a motor 403. The first filter screen 5 is swaying left and right on the mounting frame 4 via the shaped rotating shaft 404, and the second filter screen 7 is positioned on the first filter screen 5. Mounting rods 501 are symmetrically arranged on both sides of the first filter screen 5. A corresponding mounting cylinder 701 is positioned on the side of the second filter screen 7 corresponding to the position of each mounting rod 501. The second filter screen 7 is positioned on the mounting rods 501 via the mounting cylinder 701. The second filter screen 7 is positioned above the first filter screen 5, thus achieving a double-layer arrangement. The mounting frame 4 includes a funnel 402, which is located below the first filter screen 5. It also includes connecting rods 6. Connecting rods 6 are symmetrically rotatably mounted on both sides of the first filter screen 5. A corresponding mounting sleeve 406 is rotatably mounted on the mounting frame 4 corresponding to the position of each connecting rod 6. The lower end of the connecting rod 6 is installed in the corresponding mounting sleeve 406. The irregularly shaped rotating shaft 404 has a structure with one end protruding, and a linkage 405 is rotatably mounted on the protruding part. A linkage seat 504 is located at the lower end of the first filter screen 5 corresponding to the linkage 405. The end of the linkage 405 away from the irregularly shaped rotating shaft 404 is rotatably mounted on the linkage seat 504. The four corners of the first filter screen 5 are supported on the mounting frame 4 by connecting rods 6, thus allowing the first filter screen 5, the second filter screen 7, and the connecting rods 6 to be movably arranged in a quadrilateral shape. Then, driven by the irregularly shaped rotating shaft 404 and the linkage 405, the first filter screen 5 and the second filter screen 7 can swing and vibrate left and right. This achieves vibratory screening of the first filter screen 5 and the second filter screen 7.

[0033] like Figure 1 , Figure 2 and Figures 4-7As shown, the first filter screen 5 has an openable and closable first guide plate 503 at the end away from the second support column 3, and the second filter screen 7 has an openable and closable second guide plate 703 at the end away from the second support column 3. The first filter screen 5 has a first discharge hopper 502 at the end away from the second support column 3, and the lower end of the first guide plate 503 is rotatably installed in the first discharge hopper 502; the second filter screen 7 has a second discharge hopper 702 at the end away from the second support column 3, and the lower end of the second guide plate 703 is rotatably installed in the second discharge hopper 702; the length of the second discharge hopper 702 is greater than the length of the first discharge hopper 502. Additionally, a latch 9 is included, with latches 9 on the lower end faces of both the first guide plate 503 and the second discharge hopper 702; the latch 9 includes a locking plate 901 and an elastic telescopic member 902, the locking plate 901 having a hook-shaped structure, and the locking plate 901 is installed on the lower end face of the first guide plate 503 or the second discharge hopper 702 via the elastic telescopic member 902. The first filter screen 5 and the second filter screen 7 are open at one end. The first guide plate 503 and the second guide plate 703 have the same structure. The first guide plate 503 is rotatably mounted on the first hopper 502. When the equipment is screening materials, the first hopper 502 can be rotated to a vertical position, thus fitting against the open end of the first filter screen 5. It is then hung on the mounting frame 4 by the locking plate 901, thereby preventing the first guide plate 503 from opening automatically. This can block the material and prevent it from falling out during the vibrating screening process. After screening, the first guide plate 503 can be placed flat on the first hopper 502, and then the equipment can be tilted by the second support column 3, allowing the material to be poured out. Similarly, the second guide plate 703 on the second filter screen 7 has the same function as the first guide plate 503.

The upper end of the electric telescopic rod 10 is rotatably provided with the support wheel 1001. The lower end of the mounting frame 4 is provided with a support groove 407 corresponding to the support wheel 1001. The electric telescopic rod 10 abuts against the support groove 407 through the support wheel 1001, and as the electric telescopic rod 10 rises, it lifts the mounting frame 4 along the support groove 407.
