Description

Technical Field

[0001] This utility model relates to the field of ore screening technology, specifically a multi-stage stone screening device for mining. Background Technology

[0002] Ore refers to rocks containing useful minerals or metals that are extracted from the Earth's crust. They are formed through geological processes and usually require various beneficiation and metallurgical processes to extract valuable components. During the mining process, ore needs to be screened and classified, which requires the use of ore screening machines. However, existing ore screening machines generate a lot of dust during the screening process, affecting the surrounding air environment. Furthermore, the multi-stage screening process using a spiral structure to push the ore forward results in poor screening efficiency.

[0003] To address the aforementioned issues, CN202323282670.0 discloses a "multi-stage ore screening device." This device uses a support rod, a cleaning brush, and a water spray pipe to spray water for dust suppression. The cleaning brush also helps to wash the multi-stage screening cylinders, ensuring effective screening. However, this device still has certain drawbacks in practical use. For example, when suppressing dust in the multi-stage screening cylinders, continuous water spraying is required, which wastes a significant amount of water. Furthermore, when screening ores, larger ores may not be able to pass through the multi-stage screening cylinders, resulting in ore residue inside and affecting the screening efficiency.

Detailed Implementation

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-6 As shown, a multi-stage screening equipment for mining includes: a screening cylinder 1, an outer frame 101 on the outside of the screening cylinder 1, a feeding frame 102 on one side of the outer end of the outer frame 101, three collection frames 103 at the bottom of the outer frame 101, and a screening component inside the feeding frame 102 for screening larger ore. The screening component includes: a screening screen 2, a discharge port 201, a guide frame 202, and a collection box 203. A dust suppression component is provided at the bottom of the screening cylinder 1 for dust suppression inside the collection frames 103. The dust suppression component includes: a discharge frame 3, a cover plate 301, a water inlet pipe 302, and a water spray head 303.

[0023] The feeding frame 102 is equipped with a screen 2 inside. A discharge port 201 is opened on one side of the inner wall of the feeding frame 102. A guide frame 202 is connected to one side of the outer end of the feeding frame 102. A collection box 203 is set at the bottom of the guide frame 202. When using the device, the ore to be screened is poured into the feeding frame 102 and falls on top of the screen 2. The screen 2 performs preliminary screening of the ore, so that larger ore is isolated at the top of the screen 2, thereby preventing larger ore from entering the screening cylinder 1 and not being screened out. The larger ore is guided by the screen 2 to the discharge port 201 and enters the guide frame 202 through the discharge port 201. Then, the guide frame 202 guides the larger ore into the collection box 203.

[0024] The outer frame 101 is connected to a discharge frame 3 at its bottom, and a cover plate 301 is connected to the bottom of the discharge frame 3. Water inlet pipes 302 are connected to both sides of the top of the cover plate 301. Multiple water spray heads 303 are connected to the bottom of the water inlet pipes 302. When the ore in the screening cylinder 1 is screened out, it will fall into the discharge frame 3 through the opening at the bottom of the outer frame 101. The discharge frame 3 guides the ore into the dropping chute 4, so that the ore falls into the collection frame 103 through the dropping chute 4. When it is necessary to transfer the ore inside the collection frame 103, one end of the water inlet pipe 302 can be connected to an external water source, and water can be guided into the water spray head 303 through the water inlet pipe 302. Finally, the water spray head 303 sprays water to reduce dust inside the collection frame 103. At this time, the collection frame 103 can be removed from the bottom of the cover plate 103, and then the ore inside the collection frame 103 can be transferred.

[0025] The cover plate 103 has three material discharge slots 4 on its top. Support seats 401 are connected to both sides of the bottom of the cover plate 103. A horizontal plate 402 is provided on the top of the cover plate 103. A vertical plate 403 is installed between the horizontal plate 402 and the cover plate 103. The support seats 401 are used to support the cover plate 103 on the ground. The vertical plate 403 is used to fix the horizontal plate 402 to the top of the cover plate 103. Connecting plates are installed on both sides of the top of the horizontal plate 402. The top of the connecting plates is connected to the outer frame 101, thereby fixing the outer frame 101 to the top of the horizontal plate 402.

[0026] A servo motor 5 is installed on one side of the top of the horizontal plate 402. A drive gear 501 is connected to one side of the outer end of the servo motor 5. A ring-shaped drive ring 502 is connected to one side of the outer end of the screening cylinder 1. Multiple teeth 503 are connected to the outer side of the drive ring 502. The drive ring 502 is connected to the drive gear 501 through the teeth 503. When the screening cylinder 1 is in use, the drive gear 501 is driven to rotate by the servo motor 5. The drive gear 501 then drives the drive ring 502 and the screening cylinder through the teeth 503. 1. Rotation: Since multiple screen holes are provided on the outside of the screening cylinder 1, the ore inside the screening cylinder 1 can be discharged from the screening cylinder 1 through the screen holes when the screening cylinder 1 rotates. The ore will also fall into the discharge frame 3 through the opening at the bottom of the outer frame 101. The discharge frame 3 guides the ore into the discharge chute 4, so that the ore falls into the collection frame 103 through the discharge chute 4. One end of the screening cylinder 1 is rotatably connected to the outer frame 101 through a bearing, thus supporting one side of the screening cylinder 1 and ensuring the rotation of the screening cylinder 1.

[0027] The outer frame 101 has an opening 6 on one side of its outer end, the bottom of the feeding frame 102 is connected to the feeding pipe 601, the screening cylinder 1 has a through hole on one side of its outer end, and one end of the feeding pipe 601 extends into the screening cylinder 1. When the ore in the feeding frame 102 passes through the screening screen 2, it will fall into the feeding pipe 601. The feeding pipe 601 will then guide the ore into the screening cylinder 1 for screening. The screening cylinder 1 has multiple screen holes of different sizes on its outer side, so the screening cylinder 1 can perform multi-stage screening of the ore and transport the ore of different sizes to the three collection frames 103 through the three discharge frames 3.

[0028] The bottom of the collection frame 103 is equipped with multiple pulleys 7 and multiple drainage holes 701. The pulleys 7 facilitate the movement of the collection frame 103, and after the water spray head 303 sprays water into the inside of the collection frame 103, the water inside the collection frame 103 can be discharged from the drainage holes 701 to the outside of the collection frame 103.

[0029] Working principle

[0030] When using this device: the ore to be screened is poured into the feeding frame 102 and falls on top of the screening screen 2. The screening screen 2 performs preliminary screening of the ore, keeping larger pieces isolated at the top of the screen, thus preventing them from entering the screening cylinder 1 and failing to be screened. The larger pieces are guided through the screening screen 2 to the discharge port 201 and then through the discharge port 201 into the guide frame 202. The guide frame 202 then guides the larger pieces into the collection box 203. The ore in the feeding frame 102 falls into the feeding pipe 601 after passing through the screening screen 2. The feeding pipe 601 then guides the ore into the screening cylinder 1. Finally, the servo motor 5 drives the drive gear 501 to rotate. 1. The toothed ring 503 drives the rotating ring 502 and the screening cylinder 1 to rotate, thereby enhancing the screening efficiency of the screening cylinder 1 for ore. After the ore in the screening cylinder 1 is screened out, it will fall into the discharge frame 3 through the opening at the bottom of the outer frame 101. The discharge frame 3 guides the ore into the discharge chute 4, so that the ore falls into the collection frame 103 through the discharge chute 4. When it is necessary to transfer the ore inside the collection frame 103, one end of the water inlet pipe 302 can be connected to an external water source, and the water can be guided to the spray head 303 through the water inlet pipe 302. Finally, the spray head 303 sprays water to reduce dust inside the collection frame 103. At this time, the collection frame 103 can be removed from the bottom of the cover plate 103, and then the ore inside the collection frame 103 can be transferred.
