Abstract
Description
Technical Field
[0001] This utility model relates to the field of mineral processing technology, and in particular to a uniform feeding device for vibrating screening operations. Background Technology
[0002] In the current mineral processing industry, a crucial prerequisite for the efficient recovery and utilization of target minerals is the crushing and grinding of the ore to a certain fineness followed by separation. Therefore, crushing has become an indispensable part of the mineral processing workflow. However, vibrating screening is a vital component of the crushing process, and its efficiency directly impacts the overall production efficiency of the crushing process.
[0003] In the current industry, vibrating screening operations typically involve conveyor belts directly transporting materials to the vibrating screen mesh for particle size classification. Because the belt width is smaller than the screen mesh, the material concentrates at a single point on the screen, failing to distribute evenly across the screen surface. This results in concentrated material impact on the screen, excessively thick material in certain areas, and short residence time on the screen, making effective classification difficult. These problems lead to low efficiency in vibrating screening operations, high equipment wear, and a situation where some qualified materials remain in the crushing process for extended periods, while some materials are easily over-crushed. This results in low process efficiency, high energy consumption, and frequent manual maintenance. Utility Model Content

The vibrating plate is mounted on the support frame via the support spring, and the vibrating motor is mounted on the end face of the vibrating plate near the support frame. The vibrating motor is located at the center of the vibrating plate.
[0009] Based on the structure of the above-mentioned uniform feeding device for vibrating screening, the support frame is further provided with an upper limiting plate, a left limiting plate, and a right limiting plate to restrict the position of the vibrating plate; the left limiting plate and the right limiting plate are respectively located on the left and right sides of the vibrating plate, and are both set at a predetermined distance from the edge of the vibrating plate; the upper limiting plate is set on the top of the vibrating plate and is set at a predetermined distance from the edge of the vibrating plate.
[0010] Based on the structure of the above-mentioned vibrating screening uniform feeding device, the upper limiting plate is provided with a scraper extending to the bottom of the transmission component, and the rear baffle is provided with a mating groove that cooperates with the scraper; the scraper passes through the mating groove.

[0012] Based on the structure of the above-mentioned vibrating screen uniform feeding device, the diversion part includes a diversion plate and a baffle plate. The baffle plate is arranged perpendicular to the vibrating plate and is arranged on both sides of the vibrating plate. The diversion plate is arranged in multiple layers on the vibrating plate along the direction from the first end to the second end, and the number of diversion plates in each layer increases gradually from the direction from the first end to the second end on the vibrating plate, and they are staggered.

In the second layer, the front end of each diversion plate is embedded in the range of the end of the first layer diversion plate, and the front end of each diversion plate in the third layer is embedded in the range of the end of the second layer diversion plate.

On the other hand, the relatively uniform material can be spread evenly on all the screen surfaces of the vibrating screen through multiple channels, which can prolong the residence time of the material on the vibrating screen, enabling the material to be effectively graded, reducing the overall production energy consumption, and reducing the difficulty of later maintenance.

[0025] Example 1
[0026] like Figures 1-2 As shown, this utility model provides a technical solution:
[0027] A uniform feeding device for vibrating screening includes, but is not limited to, a transmission component 1, a screening component 2, and a vibrating screen 3; the transmission component 1 is located at the inlet of the screening component 2; the vibrating screen 3 is located at the outlet of the screening component 2; the screening component 2 is provided with a diversion section for diverting the material and a vibrating component for vibrating the material.
[0028] Based on the above structure, the material is transported from the conveying component 1 to the screening component 2. The material is dispersed into multiple material streams by the diversion section in the screening component 2, avoiding the material from falling directly into the vibrating screen 3 in a pile. By diverting the material into multiple channels, the material can fall into the vibrating screen 3 more evenly. On the one hand, it can avoid the material from being too concentrated and causing local damage to the vibrating screen 3. On the other hand, the relatively uniform material can be spread evenly on all the screen surfaces of the vibrating screen 3 through multiple channels, which can prolong the residence time of the material on the vibrating screen 3, so that the material can be effectively classified, reducing the overall production energy consumption and reducing the difficulty of later maintenance.
[0029] As an example, a receiving hopper 4 can be provided at the contact part between the screening component 2 and the conveying component 1; the receiving hopper 4 may include a front baffle 41, a rear baffle 42 and a side baffle 43; the front baffle 41 and the rear baffle 42 are arranged in parallel, and the side baffle 43 is symmetrically arranged between the front baffle 41 and the rear baffle 42, forming a funnel-shaped structure; the rear baffle 42 and the side baffle 43 are connected to the screening component 2, and the front baffle 41 is set at a predetermined distance from the screening component 2.
[0030] Based on the above structure, by setting a funnel-shaped receiving hopper 4, the material transported by the conveying component 1 can be received to prevent spillage. At the same time, the funnel-shaped cavity structure also has a certain holding function, which can place the material in the receiving hopper 4 when the conveying component transports too much material. Setting the front baffle 41 at a predetermined distance from the surface of the screening component 2 can limit the discharge speed and make the diversion more uniform.
[0031] As an example, the distance between the front baffle 41 and the screening assembly 2 is 30-60 mm.
[0032] Based on the above structure, since the front-end process will crush the material, the maximum size of the crushed material usually does not exceed 30mm. Therefore, the distance between the front baffle 41 and the screening component 2 is specially set so that at least one layer of material is conveyed out of the receiving hopper 4. At the same time, a vibration component is also set in the screening component 2, which can discharge the material more efficiently.
[0033] As an example, the screening assembly 2 may include a support frame 21, a vibrating plate 22, a support spring 23, and a vibration motor 24. The vibrating plate 22 is mounted on the support frame 21 via the support spring 23, and the vibration motor 24 is mounted on the end face of the vibrating plate 22 near the support frame 21. The vibration motor 24 may be located at the center of the vibrating plate 22.
[0034] Based on the above structure, the support spring 23 can reduce the noise when the material falls, and enhance the vibration effect of the vibrating motor 24, so that the material can fall quickly. Setting the vibrating motor 24 in the center position can make the overall vibration force more balanced.
[0035] As an example, the support frame 21 is also provided with an upper limiting plate 25, a left limiting plate 26, and a right limiting plate 27 to restrict the position of the vibrating plate 22; the left limiting plate 26 and the right limiting plate 27 are respectively provided on the left and right sides of the vibrating plate, and are both set at a predetermined distance from the edge of the vibrating plate 22; the upper limiting plate 25 is set on the top of the vibrating plate 22 and is set at a predetermined distance from the edge of the vibrating plate 22.
[0036] Based on the above structure, the vibration range of the vibrating plate 22 is limited by the upper limiting plate 25, the left limiting plate 26 and the right limiting plate 27, making the entire vibration process smoother.
[0037] As an example, a scraper 28 extending to the bottom of the transmission assembly 1 may be provided on the upper limiting plate 25, and a mating groove 29 that cooperates with the scraper 28 is provided on the rear baffle 42; the scraper 28 is provided through the mating groove 29.
[0038] Based on the above structure, the material attached to the conveying component 1 can be scraped off by setting the scraper 28, and the mating groove 29 can ensure that the hanging plate and the rear baffle 42 do not interfere during the vibration of the vibrating plate 22.
[0039] As an example, the vibrating plate 22 is an isosceles trapezoidal structure. The end of the vibrating plate 22 closer to the transmission component 1 is the first end 210, and the end of the vibrating plate 22 away from the transmission component 1 is the second end 211. The size of the first end 210 is smaller than the size of the second end 211.
[0040] The diversion section may include a diversion plate 212 and a baffle plate 213. The baffle plate 213 is arranged perpendicular to the vibrating plate 22 and is arranged on both sides of the vibrating plate 22. The diversion plate 212 is arranged in multiple layers on the vibrating plate 22 along the direction from the first end 210 to the second end 211. The number of diversion plates in each layer increases gradually from the direction from the first end 210 to the second end 211 on the vibrating plate 22 and is arranged in an alternating manner.
[0041] Based on the above structure, by setting the material distribution plates to be multiple layers arranged in an alternating manner, the material can be subdivided evenly layer by layer when passing through each layer of the material distribution plate, and then fall sequentially under the action of the vibration motor 24.
[0042] As an example, the splitter plate 212 is configured as three layers, with two first-layer splitter plates 212, three second-layer splitter plates 212, and four third-layer splitter plates 212; the front end of each splitter plate 212 in the second layer is embedded in the range of the end of the first-layer splitter plate 212, and the front end of each splitter plate 212 in the third layer is embedded in the range of the end of the second-layer splitter plate 212.
[0043] Based on the above structure, by embedding each layer of diversion plate 212 into the area where the upper layer of diversion plate 212 is located, the material can be better diverted, avoiding material jamming.
[0044] As an example, the diverter plate 212 as a whole can be a sharp structure, with its sharp end being the front end.
[0045] As an example, the height of the diverter 212 is not less than 30mm, and the height of the baffle 213 is not less than 60mm. This allows for effective diversion and blocking of materials.
[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
