Description

Technical Field

[0001] This utility model provides a uniform distribution plate for easy ore screening, belonging to the technical field of mining machinery and equipment. Background Technology

[0002] Screening is an indispensable part of the entire ore (or sand and gravel aggregate) crushing production line. Vibrating screens are the main screening equipment. Therefore, screening performance will directly affect the capacity, circulating load and production cost of the entire system.

[0003] In the field of ore screening, the uneven distribution of ore at the feed end of traditional equipment often leads to low screening efficiency. In existing technologies, ore entering screening equipment is prone to accumulation, deviation, or concentrated feeding, causing localized overload of the screen, increased wear, and even clogging of the screen holes. While some equipment uses diverter plates or guide structures, and some screening equipment uses simple guide plates or baffles, these devices typically only provide limited guidance for the material and cannot achieve truly uniform distribution. For example, simple flat guide plates cannot effectively overcome the tendency of material to concentrate due to inertia, while baffles easily cause material to split into channels, resulting in uneven material layer thickness in each channel and an unsatisfactory diversion effect. Therefore, this utility model provides a uniform distribution plate body for convenient ore screening. Utility Model Content

[0004] The technical problem solved by this utility model is that when ore lacking flow guidance enters the screening equipment, it is easy to accumulate, deviate, or concentrate the material. Simple diversion plates or flow guidance structures are not ideal for diverting ore.

[0005] To solve the technical problem, the technical solution provided by this utility model is as follows: a uniform distribution plate body for easy ore screening, including a base plate, a steep inclined slope on one side of the top of the base plate, a gentle inclined slope on the other side of the top of the base plate, a plurality of flow guiding partition plates are equidistantly arranged on the top of the gentle inclined slope, a V-shaped groove is formed on the upper slope surface of the steep inclined slope away from the flow guiding partition plate, an inverted V-shaped flow dividing plate is provided on the slope surface of the steep inclined slope, and a plurality of dividing teeth are equidistantly arranged above the flow guiding partition plate at the bottom of the inverted V-shaped flow dividing plate.

[0006] Furthermore, a barrier is installed at the edge of the steep landslide slope.

[0007] Furthermore, the inclined steep landslide is symmetrically reinforced with reinforcing ribs on both sides, and the side wall of the inclined steep landslide away from the flow guide plate is fixedly welded to the inner wall of the feed end of the ore screening equipment with the reinforcing ribs.

[0008] Furthermore, the inclined steep landslide, inclined gentle landslide, V-shaped diverter plate, and flow guide plate are all coated with a wear-resistant ceramic layer.

[0009] Furthermore, the flow guide plate has a flared plate fixedly connected to the top of the substrate on the side wall away from the steep slope, and the cross-section of the flared plate is an isosceles acute triangle.

[0010] Furthermore, the substrate, steep inclined slope, gentle inclined slope, V-shaped diverter plate, and flow guide plate are all made of wear-resistant materials, which are either high-manganese steel or high-chromium cast iron.

[0011] The beneficial effects of this utility model are: The steep, sloping landslide allows the ore to slide down quickly, preventing accumulation. The V-shaped chute guides the ore, and the inverted V-shaped diversion plate diverts the ore laterally. The dividing teeth further break up agglomerated ore. The gentle, sloping landslide slows down the ore flow rate. Combined with the flow guide and divider plate, the ore flow is subdivided into multiple uniform streams. The flared plate expands the ore diffusion range, preventing local accumulation and achieving multi-level distribution buffering. This guides and evenly disperses the ore material, preventing accumulation, deviation, or concentrated feeding. The diversion effect is more ideal, improving the utilization rate of the screen.

[0021] According to the appendix Figure 1-5 As shown: This utility model provides a uniform distribution plate for easy ore screening: it includes a base plate 1, an inclined steep slope 2 on one side of the top of the base plate 1, and an inclined gentle slope 7 on the other side of the top of the base plate 1, which is placed on the side of the inclined steep slope 2. Several guide partition plates 3 are equidistantly arranged on the top of the inclined gentle slope 7. A retaining wall 8 is provided at the edge of the inclined steep slope 2 to prevent ore overflow or deformation due to impact. A V-shaped groove 4 is formed on the upper slope of the inclined steep slope 2 away from the guide partition plate 3. An inverted V-shaped diversion plate 5 is provided on the slope of the inclined steep slope 2. Several guide partition plates 3 are equidistantly arranged at the bottom of the inverted V-shaped diversion plate 5. The dividing teeth 6 above the dividing plate 3, and the flared plate 10 fixedly connected to the top of the base plate 1 on the side wall of the flow guiding dividing plate 3 away from the inclined steep slope 2. The cross-section of the flared plate 10 is an isosceles acute triangle. Specifically, the inclined steep slope 2 with a large slope allows the ore to slide down quickly and avoid accumulation. The V-shaped chute 4 on the surface of the inclined steep slope 2 guides the ore. The ore is laterally divided by the inverted V-shaped diversion plate 5. The dividing teeth 6 further break up the agglomerated ore to achieve multi-level distribution buffering. The inclined gentle slope 7 with a smaller slope slows down the ore flow rate. Together with the flow guiding dividing plate 3, the ore flow is subdivided into multiple uniform material flows, improving the screen utilization rate.

[0022] As per the instruction manual Figure 1As shown: The inclined steep slope 2 is symmetrically equipped with reinforcing ribs 9 on both sides. The side wall of the inclined steep slope 2 away from the guide partition plate 3 is fixedly welded with reinforcing ribs 9 to the inner wall of the feed end of the ore screening equipment. Specifically, during installation, the equal distribution plate is placed at the feed end of the screening equipment, directly below the feed trough outlet and before the starting position of the screen, to guide and evenly disperse the ore material falling from the feed end of the ore screening equipment towards the screen of the ore screening equipment.

[0023] As an optional embodiment, the inclined steep landslide 2, the inclined gentle landslide 7, the V-shaped diverter plate 5, and the flow guide plate 3 are all coated with a wear-resistant ceramic layer. The substrate 1, the inclined steep landslide 2, the inclined gentle landslide 7, the V-shaped diverter plate 5, and the flow guide plate 3 are all made of wear-resistant materials, which are either high-manganese steel or high-chromium cast iron. Considering the high hardness and strong abrasiveness of the ore material, it is to ensure that the inclined steep landslide 2, the inclined gentle landslide 7, the V-shaped diverter plate 5, and the flow guide plate 3 obtain high hardness, high toughness, and excellent impact wear resistance.

[0024] The principle of this utility model During operation, the falling ore material first impacts the inclined steep slope 2, using its large slope to allow the ore to slide down quickly and avoid accumulation. The V-shaped chute 4 on the surface of the inclined steep slope 2 guides the ore, which is then laterally diverted by the inverted V-shaped diversion plate 5. The dividing teeth 6 further break up the clumps of ore. The inclined gentle slope 7 with a smaller slope slows down the ore flow rate. Together with the flow guide plate 3, the ore flow is subdivided into multiple uniform streams. The flared plate 10 with an isosceles acute triangular cross section expands the ore diffusion range, preventing local accumulation and achieving multi-level distribution buffering. The ore material falling from the feed end of the ore screening equipment is guided and evenly dispersed towards the screen of the ore screening equipment to prevent ore accumulation, deviation, or concentrated feeding. The diversion effect is more ideal, improving the screen utilization rate.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
