[0002] Mineral extraction is an indispensable part of the mining process, which aims to extract valuable minerals from natural ores. This process is complex and multi-stage, typically including exploration, mining, crushing, grinding, separation and purification.

[0003] The commonly used screening and crushing devices for mineral extraction crush the minerals to be extracted within the device, and then the filter screen at the bottom of the device performs fine crushing and screening. Although this method can perform fine crushing and screening, the filter screen will be subjected to great pressure during use due to the weight of the minerals, which leads to the need for frequent replacement and maintenance of the filter screen. Therefore, there is an urgent need for a vertical screening and crushing device with higher filter screen strength.

[0004] In view of this, the present utility model is proposed. Utility Model Content

All the force-bearing rings and force-bearing rods at the bottom of the filter screen are in a spider web shape, and the position of each filter hole can be staggered from the position of all the force-bearing rings and force-bearing rods.

[0012] In a preferred embodiment of the present invention, the durable structure further includes a feed pipe, a solid block, a spring groove, and a spring groove.

[0013] In a preferred embodiment of this utility model, the feed pipe is an L-shaped hollow rectangular pipe, the bottom of which can communicate with the inside of the processing cylinder. The connection between the feed pipe and the processing cylinder is flush with the top of the filter screen. Multiple solid blocks are arranged in a circular array on the inner wall of the processing cylinder. Each solid block has the same spring groove and spring slot on its top. The spring groove is a rectangular slot that can fit the size below the end of the force rod. The spring slot is a circular slot that allows the force rod to slide within the spring groove.

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a vertical screening and crushing device includes: a processing cylinder 20, which is a hollow cylindrical shape, with a discharge port at the bottom of the processing cylinder 20, a motor 21 fixedly connected to the top of the processing cylinder 20, and crushing teeth 23 fixedly connected inside the cavity of the processing cylinder 20. The crushing teeth 23 are annular with a triangular cross section, and multiple crushing teeth 23 are evenly arranged inside the cavity of the processing cylinder 20.

[0029] The rotating shaft 24 is cylindrical and is rotatably connected to the top center of the cavity of the processing cylinder 20. A striking rod 25 is fixedly connected to the arc surface of the rotating shaft 24. The striking rod 25 is a rod with a triangular cross section. Multiple striking rods 25 are evenly arranged on the arc surface of the rotating shaft 24. The motor 21 is electrically connected to the corresponding power supply. This is existing technology and will not be described in detail here.

[0030] like Figure 1 , Figure 2, Figure 3 and Figure 4 As shown, the durable structure, set inside the cavity of the processing cylinder 20, has strong compressive strength. The screening structure includes: a filter screen 30, filter holes 31, a force ring 32, and a force rod 33. The filter screen 30 is movably connected inside the cavity of the processing cylinder 20. The filter holes 31 are opened at the top of the filter screen 30. The force ring 32 is fixedly connected to the bottom of the filter screen 30. The force rod 33 is also fixedly connected to the bottom of the filter screen 30. The filter holes 31 can screen minerals.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the filter screen 30 is a disc-shaped structure with a concave top. The filter holes 31 are circular openings, and multiple filter holes 31 are opened through the top of the filter screen 30. The filter holes 31 on the top of the filter screen 30 are arranged in a circular array. The force-receiving rings 32 are circular, and multiple force-receiving rings 32 are evenly arranged at the bottom of the filter screen 30. The diameter of each force-receiving ring 32 is larger than the diameter of another force-receiving ring 32 in its cavity. The force-receiving rods 33 are rectangular plates, and multiple force-receiving rods 33 are arranged in a circular array at the bottom of the filter screen 30. Each force-receiving rod 33 can also be fixedly connected to all the force-receiving rings 32. All the force-receiving rings 32 and force-receiving rods 33 at the bottom of the filter screen 30 are arranged in a spider web pattern. The position of each filter hole 31 can be staggered from the position of all the force-receiving rings 32 and force-receiving rods 33. The durable structure also includes a feed pipe 22, a solid block 34, a spring groove 35, and a spring groove 36. The feed tube 22 is fixedly connected to the outer wall of the processing cylinder 20, the solid block 34 is fixedly connected to the inner wall of the processing cylinder 20, the spring groove 35 is opened on the top of the solid block 34, and the spring groove 36 is opened on the top of the solid block 34 inside the spring groove 35. The feed tube 22 is an L-shaped hollow rectangular pipe. The bottom of the feed tube 22 can communicate with the inside of the processing cylinder 20. The connection position between the feed tube 22 and the processing cylinder 20 is flush with the top of the filter screen 30. Multiple solid blocks 34 are arranged in a ring array on the inner wall of the processing cylinder 20. Each solid block 34 has the same spring groove 35 and spring groove 36 on its top. The spring groove 35 is a rectangular slot and can be adapted to the size below the end of the force rod 33. The spring groove 36 is a circular groove and the force rod 33 can slide in the spring groove 35. A spring is also fixedly connected in the spring groove 36. The top of the spring is fixedly connected to the bottom of the end of the force rod 33.

[0032] In practical use, the minerals to be finely crushed and screened are added from the top of the feed pipe 22, and the power to the motor 21 is turned on. When the minerals enter the feed pipe 22, they will flow along the feed pipe 22 into the cavity of the processing cylinder 20 and fall onto the top of the filter screen 30. At this time, the motor 21 drives the rotating shaft 24 to rotate, and the rotating shaft 24 will drive the hitting rod 25 to rotate. When the hitting rod 25 rotates, it will knock the minerals on the top of the filter screen 30 against the wall of the crushing teeth 23. At this time, the minerals will be rebounded by the crushing teeth 23 and cooperate with the rotating hitting rod 25. The mineral is crushed into the required powder and falls onto the top of the filter screen 30. The mineral powder passes through the filter hole 31 and is finally discharged from the discharge port at the bottom of the processing cylinder 20. When the mineral falls onto the top of the filter screen 30, the force rod 33 and the force ring 32 move downwards in sync and drive the filter screen 30 to move at the same time. At this time, the spring at the bottom of the force rod 33 will contract and then extend, thereby pushing the force rod 33 upwards and driving the filter screen 30 to move upwards, thereby relieving the force on the filter screen 30.

[0033] In summary, by setting up a durable structure, the filter screen 30 can have a longer service life. The durable structure reinforces the bottom of the filter screen 30 through the force ring 32 and the force rod 33, and the spring at the bottom of the force rod 33 buffers the filter screen 30 when it is under force. In addition, when the feed pipe 22 introduces minerals, there will be no huge drop between it and the filter screen 30, so that it will hit the top of the filter screen 30. Therefore, the filter screen 30 of this solution can have a longer service life without frequent replacement and maintenance.

[0034] like Figure 2 and Figure 5 As shown, the wall of the rotating shaft 24 is provided with a rework structure, which includes a rotating block 37 and a scraper 38. The rotating block 37 is fixedly connected to the bottom of the rotating shaft 24, and the scraper 38 is fixedly connected to the wall of the rotating block 37. The rotating block 37 is a rectangular block, and the scraper 38 is symmetrically arranged on both sides of the rotating block 37. The scraper 38 is a rod with a right-angled triangular cross section. The bottom of the scraper 38 can contact the top of the filter screen 30. A rectangular plate that can block the spacing between the symmetrical scrapers 38 at the bottom of the rotating block 37 is also fixedly connected.

[0035] In actual use, the rotating shaft 24 will drive the rotating block 37 to rotate synchronously when it rotates, and the rotating block 37 will drive the shovel 38 to rotate. When the shovel 38 rotates, it will scrape the top of the filter screen 30. If the minerals on the top of the filter screen 30 are not completely crushed at this time, they will be shoveled away to contact the crushing teeth 23 for repeated crushing.

[0036] In summary, by setting the shovel bar 38, the minerals can be repeatedly crushed by shoveling them, thereby effectively improving the fine crushing and screening quality of the device and enabling this scheme to have a stable output quality.

[0037] Working principle: The minerals to be finely crushed and screened are added from the top of the feed pipe 22, and the power to the motor 21 is turned on. When the minerals enter the feed pipe 22, they will flow into the cavity of the processing cylinder 20 and fall onto the top of the filter screen 30. At this time, the motor 21 drives the rotating shaft 24 to rotate, which in turn drives the hitting rod 25 to rotate. When the hitting rod 25 rotates, it will knock the minerals on the top of the filter screen 30 against the wall of the crushing teeth 23. At this time, the minerals will be rebounded by the crushing teeth 23 and, together with the rotating hitting rod 25, will impact the crushing teeth 23. The mineral is crushed and then falls onto the top of the filter screen 30. The mineral powder passes through the filter hole 31 and is finally discharged from the discharge port at the bottom of the processing cylinder 20. When the mineral falls onto the top of the filter screen 30, the force rod 33 and the force ring 32 move downwards in sync and drive the filter screen 30 to move at the same time. At this time, the spring at the bottom of the force rod 33 will contract and then extend, thereby pushing the force rod 33 upwards and driving the filter screen 30 to move upwards, thereby releasing the force on the filter screen 30.
