Description

Technical field:

[0001] The utility model relates to the technical field of coarse coal slime separators, in particular to a separator feeding device of the coarse coal slime separator. Background technology:

[0002] A coarse coal slime separator is a device that realizes intelligent sorting under the action of rising water flow and intelligent jammer based on the difference in interference sedimentation velocity of materials. When working, the material enters the sorting barrel through the feed barrel, and the material is mixed with the rising water flow to form an "interference bed". The material (clean coal) with a density lower than the sorting density moves upward, and the material (tailings) with a density higher than the sorting density moves downward, thereby completing the sorting. In the prior art, a scattering blade is usually designed in the feed barrel to disperse the input material, but the dispersion effect of the scattering blade is not ideal. Because the diameter of the sorting barrel is huge, it is difficult for the scattering blade to scatter the input material to cover the entire liquid surface of the sorting barrel. The material still enters the center of the sorting barrel in a relatively concentrated manner, thereby affecting the sorting effect of the coarse coal slime separator. Utility model content:

[0003] The utility model aims to provide a sorting feed device for a coarse coal slime sorter to solve the technical problem in the prior art that the feed of the coarse coal slime sorter is unevenly distributed and affects the sorting effect of the coarse coal slime sorter.

[0004] Contents of the utility model: A sorting and feeding device of a coarse coal slime sorter, comprising a feeding barrel with an opening at the bottom, a feeding pipe installed on the top of the feeding barrel, a conical distribution hopper coaxially arranged below the feeding barrel, a plurality of annular distribution ring grooves concentrically opened on the distribution hopper, and a plurality of connecting blocks evenly distributed and connected in the distribution ring grooves.

[0005] Furthermore, an annular material stop edge is installed on the outer edge of the material distribution ring groove.

[0006] Furthermore, the material distribution hopper is installed on the feeding barrel through a plurality of vibration hanging components.

[0007] Furthermore, the vibration suspension assembly includes a sliding column, and a plurality of load-bearing platforms are evenly installed on the outer wall of the feed barrel. A through hole is opened on the load-bearing platform, and a sliding column is slidably connected in the through hole. The bottom of the sliding column is fixedly connected to the material feeding hopper, and a round table is connected to the top of the sliding column. A compression spring is mounted on the sliding column, and the compression spring is located between the load-bearing platform and the round table.

[0008] Furthermore, an anti-wear cone sleeve is coaxially arranged on the top of the material distribution hopper.

[0009] Furthermore, a pin is connected to the bottom end of the anti-wear cone sleeve, a positioning hole matching the pin is opened on the material distribution hopper, and the pin is slidably inserted in the positioning hole.

[0010] Furthermore, a plurality of overflow holes are provided on the outer wall of the feeding barrel.

[0011] The beneficial effects of the utility model are as follows: the utility model changes the traditional feeding mode of materials broken up by mechanical blades, designs a distribution hopper under the feeding barrel, and designs a distribution ring groove with a concentric circle structure on the distribution hopper, so that the coal slime is dropped in a concentric circle arrangement, covering a larger range of the liquid surface of the sorting machine's selection barrel, and distributing the material more evenly, thereby improving the sorting efficiency of the coarse coal slime sorting machine. Description of the drawings:

[0013] Figure 2 for Figure 1 A schematic diagram of the enlarged structure of part A;

[0014] Figure 3 It is a three-dimensional diagram of the utility model;

[0015] In the figure, there are a feed barrel 1, a distribution hopper 2, a distribution ring groove 3, a connecting block 4, a material stop edge 5, a load-bearing platform 6, a compression spring 7, a sliding column 8, a round table 9, a feed pipe 10, an overflow hole 11, an anti-wear cone sleeve 12, a pin 13, and a sorting machine barrel 14. Specific implementation method:

[0016] like Figure 1 As shown, a sorting and feeding device of a coarse coal slime sorter comprises a feeding barrel 1 with an opening at the bottom end, a feeding pipe 10 is installed on the top of the feeding barrel 1, a conical distribution hopper 2 is coaxially arranged below the feeding barrel 1, a plurality of annular distribution ring grooves 3 are concentrically opened on the distribution hopper 2, and a plurality of connecting blocks 4 are evenly connected in the distribution ring grooves 3 (the distribution ring grooves 3 divide the distribution hopper 2, and the connecting blocks 4 connect these divided bodies).

[0017] like Figure 2 As shown, in order to better block and control the gradual falling of coal slime, an annular material blocking edge 5 is installed on the outer edge of the distribution ring groove 3.

[0018] like Figure 1 and Figure 3As shown, the distribution hopper 2 is installed on the feeding bucket 1 through a plurality of vibration hanging components. The vibration hanging components have the function of elastic vibration, which can accelerate the falling of coal slime and prevent blockage; the vibration hanging components include a slide column 8, and a plurality of bearing platforms 6 are evenly installed on the outer wall of the feeding bucket 1. A through hole is opened on the bearing platform 6, and a slide column 8 is slidably connected in the through hole. The bottom of the slide column 8 is fixedly connected to the distribution hopper 2, and a round table 9 is connected to the top of the slide column 8. The slide column 8 is sleeved A compression spring 7 is installed, and the compression spring 7 is located between the load-bearing platform 6 and the round table 9; in order to prevent the top of the distribution hopper 2 from being eroded and worn by the coal slime, an anti-wear cone sleeve 12 is coaxially arranged on the top of the distribution hopper 2; a pin 13 is connected to the bottom end of the anti-wear cone sleeve 12, and a positioning hole matching the pin 13 is opened on the distribution hopper 2, and the pin 13 is slidably inserted in the positioning hole; in order to prevent the utility model from being blocked and unable to work, a plurality of overflow holes 11 are opened on the outer wall of the feeding barrel 1.

[0019] When doing specific work, such as Figures 1 to 3 As shown, the coal slime enters the feed barrel 1 from the feed pipe 10, first falls on the anti-wear cone sleeve 12 and is dispersed, and then the coal slime is dispersed around along the distribution hopper 2. Due to the effects of the distribution ring groove 3 and the retaining edge 5, the coal slime falls step by step in the form of multiple concentric circles, and the coal slime covers the entire liquid surface of the separator barrel 14. The coal slime distribution is more uniform, which improves the sorting of the coarse coal slime separator.
