Abstract
Description
Technical Field
[0001] This utility model relates to the field of wet screening mining machinery technology, and more specifically, to a wet screening and grading screen with a multi-layer superimposed vibrating body frame structure. Background Technology
[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which possesses certain usable properties. It can be divided into metallic minerals and non-metallic minerals. After mining, ore needs to be screened and graded, typically using wet screening machinery. Current traditional wet screening machinery generally uses a single-layer vibrating body screen with a small area. The screen surface is washed by an overall spray, resulting in significant resistance and water consumption, severely impacting screening efficiency and output. When the user's screening volume is substantial, dozens or even hundreds of traditional screening machines are required, leading to unsatisfactory screening results, huge land occupation, and high investment, maintenance, and operating costs. Therefore, we propose a multi-layer stacked vibrating body frame structure wet screening and grading screen. Utility Model Content
[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a wet screening and grading screen with a multi-layer superimposed vibrating body frame structure.
[0004] To solve the above problems, the present invention adopts the following technical solution:
[0005] A wet screening and grading screen with a multi-layer stacked vibrating frame structure includes a frame base, two uprights fixedly connected to each side of the frame base, a vibration mechanism at the top of each of the four uprights, a support mounting frame on each of the four vibration mechanisms, multiple screening boxes fixedly connected to the inner side of the four support mounting frames, a spraying mechanism on each of the multiple screening boxes, multiple screening screens at the bottom of each screening box, an S-shaped reprocessing slurry tank fixedly connected between two adjacent screening screens, a receiving hopper fixedly connected to the bottom of each screening box, a discharge port at the end of each screening box, and a dual-shaft motor fixedly installed on the top of one of the screening boxes, with cams fixedly sleeved on the two output shafts of the dual-shaft motor.
[0006] As a preferred embodiment of the present invention, the spraying mechanism includes multiple water distribution pipes fixedly sleeved in the inner cavity of the screening box, multiple spray heads fixedly connected to the bottom of the multiple water distribution pipes, the ends of the multiple water distribution pipes extending to the outside of the screening box and fixedly connected to a water distribution pipe, and a water guide pipe fixedly connected to the side of the water distribution pipe.
[0007] As a preferred embodiment of this utility model, the vibration mechanism includes a vibration cylinder fixedly connected to the top of the upright, a vibration spring fixedly connected to the bottom of the inner cavity of the vibration cylinder, a telescopic column fixedly connected to the top of the vibration spring, a mounting base fixedly connected to the side of the top of the telescopic column, and a support mounting frame fixedly mounted on the mounting base.
[0008] As a preferred embodiment of this utility model, a feeding trough is provided on the top surface of the screening box, a feeding hopper is provided in the inner cavity of the feeding trough, and a conveyor belt is provided on the feeding hopper.
[0009] As a preferred embodiment of this utility model, the bottom end of the telescopic column is fixedly connected to a sliding rod, and the bottom end of the sliding rod is movably sleeved to the bottom of the vibrating cylinder and extends into the inner cavity of the upright.
[0010] In a preferred embodiment of this utility model, the water distribution pipes are located directly above the S-shaped reconstituted slurry tank.
[0011] The advantages of this utility model are:
[0012] (1) In this utility model, multiple support mounting frames are used to connect multiple screening boxes in a stacked manner. The frame base, uprights and vibration mechanism are used to support the multiple support mounting frames. The dual-axis motor drives the cam to rotate, causing the multiple screening boxes to vibrate up and down. Thus, the mineral material is screened and graded through multiple screen boxes arranged in a stacked manner, which effectively reduces the problem of large floor space occupied by screening machinery, while improving screening efficiency and practicality.
[0013] (2) In this utility model, when the ore enters the inner cavity of the screening box through the feeding trough, the ore is first screened and graded by the first screening screen near the feeding trough in the inner cavity of the screening box. When the ore enters the first S-shaped reconstituted slurry tank, water is sprayed onto the S-shaped reconstituted slurry tank by the water guide pipe, water distribution pipe, water distribution pipe and spray head, so that the ore entering the S-shaped reconstituted slurry tank becomes slurry, so that the slurry can continue to be graded on the second screening screen. The dry slurry after re-grading enters the second S-shaped reconstituted slurry tank. The water sprayed by the spray head makes the dry slurry in the S-shaped reconstituted slurry tank become slurry again, so that the slurry can be finally screened and graded by the third screening screen, thus solving the problem of huge water consumption.

[0024] Example:
[0025] Please see Figure 1-5 A wet screening and grading screen with a multi-layer stacked vibrating frame structure includes a frame base 1, two uprights 2 fixedly connected to each side of the frame base 1, a vibration mechanism 3 at the top of each of the four uprights 2, a support mounting frame 4 on each of the four vibration mechanisms 3, multiple screening boxes 5 fixedly connected to the inner side of the four support mounting frames 4, a spraying mechanism 6 on each of the multiple screening boxes 5, multiple screening screens 9 at the bottom of the screening boxes 5, an S-shaped re-slurry water tank 10 fixedly connected between two adjacent screening screens 9, a receiving hopper 12 fixedly connected to the bottom of each screening box 5, a discharge port 11 at the end of each screening box 5, and a dual-shaft motor 7 fixedly installed on the top of one screening box 5. Cams 8 are fixedly sleeved on the two output shafts of the dual-shaft motor 7.
[0026] In this embodiment, multiple screening boxes 5 can be installed on the inner side of multiple support mounting frames 4, and the multiple screening boxes 5 are arranged vertically so that the material can be screened by multiple vertically arranged screening boxes 5, while reducing the floor space occupied by the vibrating machinery.
[0027] For details, please refer to Figure 1 and Figure 4 The spraying mechanism 6 includes multiple water distribution pipes 13 fixedly sleeved inside the screening box 5. Multiple spray heads 14 are fixedly connected to the bottom of the multiple water distribution pipes 13 respectively. The ends of the multiple water distribution pipes 13 extend to the outside of the screening box 5 and are fixedly connected to water distribution pipes 15. Water guide pipes 16 are fixedly connected to the side of the water distribution pipes 15.
[0028] In this embodiment, the end of the water guide pipe 16 is connected to an external water source. At the same time, an external water pump is used to guide external water from the water guide pipe 16 and the water distribution pipe 15 into the inner cavity of the water distribution pipe 13, so that the spray head 14 below the water distribution pipe 13 can be used for spraying.
[0029] For details, please refer to Figure 1 and Figure 4 The vibration mechanism 3 includes a vibration cylinder 17 fixedly connected to the top of the upright 2. A vibration spring 18 is fixedly connected to the bottom of the inner cavity of the vibration cylinder 17. A telescopic column 19 is fixedly connected to the top of the vibration spring 18. A mounting base 20 is fixedly connected to the side of the top of the telescopic column 19. A support mounting frame 4 is fixedly installed on the mounting base 20.
[0030] For details, please refer to Figure 1 , Figure 3 and Figure 5 The top surface of the screening box 5 is provided with a feeding trough 22, the inner cavity of the feeding trough 22 is provided with a feeding hopper 23, and a conveyor belt 24 is provided on the feeding hopper 23.
[0031] In this embodiment, the screening material is introduced into the feed hopper 23 by the conveyor belt 24 so that the material enters the screening box 5 from the feed trough 22 for screening.
[0032] For details, please refer to Figure 2 and Figure 4 The bottom end of the telescopic column 19 is fixedly connected to a slide rod 21, and the bottom end of the slide rod 21 is movably sleeved to the bottom of the vibrating cylinder 17 and extends into the inner cavity of the upright 2.
[0033] In this embodiment, the telescopic column 19 is limited by the movable connection between the slide rod 21 and the vibrating cylinder 17, thereby limiting the multiple screening boxes 5 and ensuring that the screening boxes 5 can only move up and down.
[0034] For details, please refer to Figure 2 The water distribution pipes 13 are located directly above the S-shaped reconstituted slurry tank 10.
[0035] In this embodiment, the spray head 14 below the water distribution pipe 13 can spray onto the S-shaped reconstituted slurry tank 10, so that the dry material that has lost too much water can be turned back into slurry.
[0036] Working principle: In operation, the dual-shaft motor 7 is first started to drive the cam 8 to rotate. The centrifugal force generated by the rotation of the cam 8 causes the uppermost screening box 5 to vibrate. At the same time, the support frame 4, mounting base 20, telescopic column 19 and vibration spring 18 make multiple screening boxes 5 vibrate up and down synchronously. Then, the conveyor belt 24 guides the ore into the feed hopper 23, and the ore is added from the feed trough 22 into the inner cavity of the screening box 5. Then, the first screening screen 9 at the end of the inner cavity of the screening box 5 near the feed trough 22 performs the first screening and classification of the ore. When the ore enters the first S-shaped reconstituted slurry tank 10, the water guide pipe 16, water distribution pipe 15, water distribution pipe 13 and spray head 14 spray water into the S-shaped reconstituted slurry tank. Water is sprayed onto the S-shaped reconstituted slurry tank 10 to store, mix, homogenize, distribute, and relay the mineral materials, allowing the materials on the S-shaped reconstituted slurry tank 10 to re-form a slurry with a water content of 30% to 50%. The slurry is then further classified on the second screening screen 9. The re-classified dry slurry enters the second S-shaped reconstituted slurry tank 10, where water is sprayed from the spray head 14 to turn the dry slurry in the S-shaped reconstituted slurry tank 10 back into a slurry. The slurry is then finally screened and classified using the third screening screen 9. Finally, the material screened off the screening screen 9 is discharged using the receiving hopper 12, while the unscreened material is discharged using the discharge port 11 at the end of the screening box 5.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
