[0002] Mining solid waste includes strippings and waste rock generated during mining, as well as tailings discarded during the mineral processing process. At present, the most commonly used method for disposing mining solid waste is to stockpile it. As the most traditional disposal method, stockpiling is to transport waste rock to the waste rock yard, strippings to the spoil dump, and tailings to the tailings pond. However, large-scale stockpiling of mining waste not only occupies land, but also the debris and tailings formed by the weathering of waste rock can be washed into the water area by water, dissolved and infiltrated into groundwater, and blown into the atmosphere by wind, causing environmental pollution;

[0031] A rotating shaft 1 is rotatably provided in the middle of the screening chamber 5, and the rotating shaft 1 is fixedly connected to the adsorption roller 12. The rotating shaft 1 passes through the rear end of the screening chamber 5 and is fixedly connected to the gear 3 11, and the adsorption roller 12 is correspondingly arranged in the middle of the lower side between the crushing rollers 6 on the left and right sides. The middle part of the adsorption roller 12 is made of magnetic material. A scraper 142 is movably provided on the adsorption roller 12 along the front-back direction. A through hole is provided inside the scraper 142, and the through hole is movably connected to the rotating shaft 2 14. The rotating shaft 2 14 is arranged on the right side of the screening chamber 5. A guide ball is rotatably provided in the through hole. An arc-shaped guide groove 141 is provided on the rotating shaft 2 14, and the arc-shaped guide groove 141 is slidably connected to the guide ball. The rotating shaft 2 14 passes through the rear end of the screening chamber 5 and is fixedly connected to the gear 2 10. The gear 1 9 and the gear 3 11 on the right side are respectively meshed with the gear 2 10.

[0032] Guide plates 15 are symmetrically provided on the front and rear sides of the lower part of the screening chamber 5, a screening net 151 is fixedly provided between the guide plates 15 on the front and rear sides, a cam 17 is correspondingly provided on the upper side of the guide plate 15, and the cam 17 is symmetrically arranged on the front and rear sides of the rotating shaft 14, the lower end of the guide plate 15 is in contact with a plurality of spring rods 19, the spring rods 19 are fixedly connected to the fixed plates 18, the fixed plates 18 are symmetrically arranged at the front and rear ends of the screening chamber 5, and the fixed plates 18 are fixedly arranged at the connecting part of the screening chamber 5 and the working chamber 33.

[0033] The beneficial effects of the above technical solution are:

[0034] When the motor 4 is working, it drives the right driving shaft 7 to rotate, the right driving shaft 7 drives the right gear 9 to rotate, the right gear 9 drives the left gear 9 and gear 2 10 to rotate, the left gear 9 drives the left driving shaft 7 to rotate, the left and right driving shafts 7 rotate in opposite directions, and the driving shaft 7 drives the crushing rollers 6 to rotate, and the left and right crushing rollers 6 rotate to crush the mineral solid waste to be detected that falls through the feed port 3. The feed port 3 is correspondingly arranged in the middle of the upper side between the crushing rollers 6, so that The mineral solid waste falls on the middle position of the crushing roller 6, and after being crushed, it falls on the middle part of the adsorption roller 12. The middle part of the adsorption roller 12 is a magnetic material, so that the metal material in the mineral solid waste is adsorbed. The rest of the mineral solid waste falls on the second screening net 151. The mineral solid waste that reaches the crushed particle size passes through the second screening net 151 and falls into the working chamber 33. The guide plate 15 and the left and right sides of the second screening net 151 are inclined. The mineral solid waste that does not reach the crushed particle size flows out through the left and right sides of the second screening net 151 and is collected by the collecting mechanism.

[0035] When the gear 2 10 rotates, it can drive the rotating shaft 2 14 to rotate. When the rotating shaft 2 14 rotates, the guide ball slides along the arc-shaped guide groove 141, thereby driving the scraper 142 to move forward and backward. The scraper 142 slides forward and backward along the adsorption roller 12, and can bring the metal material from the middle of the adsorption roller 12 to the front and rear sides of the adsorption roller 12, so that the metal material is separated from the magnetic adsorption area, so that the metal material falls on the guide plate 15. The rotation direction of the gear 2 10 is opposite to that of the gear 3 11, so that the rotation direction of the adsorption roller 12 is opposite to that of the rotating shaft 2 14, so that the metal material on the adsorption roller 12 falls as far away from the rotating shaft 2 14 as possible when it falls, reducing the influence of mineral solid waste on the active cooperation of the rotating shaft 2 14 and the scraper 142. The metal material falls on the guide plate 15 and flows out from the left and right sides of the guide plate 15, and is collected by the collecting mechanism;

[0036] When the rotating shaft 14 rotates, the cams 17 on the front and rear sides can be driven to rotate. When the cam 17 rotates, its protruding end contacts the guide plate 15, which can drive the guide plates 15 on the front and rear sides to move downward. The guide plate 15 drives the screening net 151 to move downward, and the spring rod 19 is compressed. After the protruding end of the cam 17 is out of contact with the guide plate 15, the guide plate 15 returns to its original position under the elastic force of the spring rod 19. When the guide plate 15 moves up and down, it drives the screening net 151 to shake up and down, thereby accelerating the collection efficiency of metal materials and the screening efficiency of crushed mineral solid waste.

[0037] Example 3

[0038] On the basis of Example 2, Figure 1-Figure 4 As shown, the front end of the screening shell 2 is provided with an opening 22, the opening 22 is communicated with the screening chamber 5, a blocking block 20 is slidably provided in the opening 22, the inclined end of the blocking block 20 is arranged corresponding to the guide plate 15, the front end of the blocking block 20 is fixedly connected to the connecting block 21, the connecting block 21 is fixedly connected to the second spring rod 23, and the second spring rod 23 is rotatably connected to the front end of the screening shell 2;

[0039] The left and right ends of the screening shell 2 are respectively provided with a discharge port 1 24 and two discharge ports 27, which are both connected to the screening chamber 5, and the two discharge ports 27 are arranged one by one with the guide plates 15 on the front and rear sides, and the discharge port 1 24 is arranged correspondingly with the screening net 2 151;

[0040] The collecting mechanism includes a sampling slot 1 25 and two sampling slots 28 respectively arranged on the left and right sides of the upper end of the detection shell 1, the sampling slot 1 25 and the discharge port 1 24 are connected in correspondence, the two sampling slots 28 are connected in correspondence with the two discharge ports 27, the two sampling slots 28 are symmetrically arranged on the front and rear sides of the sampling slot 1 25, the sampling slot 1 25 is connected with the discharge port 3 26, the two sampling slots 28 are connected in correspondence with the two discharge ports 4 29, the upper sides of the left and right ends of the detection shell 1 are respectively provided with a discharge port 3 26 and two discharge ports 4 29, and sealing plates are installed in the discharge port 3 26 and the two discharge ports 4 29.

[0041] The beneficial effects of the above technical solution are:

[0042] When the guide plate 15 moves downward, it first contacts the inclined end of the block 20, which can push the block 20 forward. When the block 20 moves, it can drive the spring rod 23 to stretch. When the guide plate 15 moves upward, it is out of contact with the inclined end of the block 20. Under the elastic action of the spring rod 23, the block 20 returns to its original position. When the screening net 151 is blocked, the gravity of the screening net 151 increases. At this time, the up and down shaking amplitude of the screening net 151 and the guide plate 15 decreases until the guide plate 15 moves to the vertical end of the block 20. At this time, the guide plate 15 cannot move up and down to drive the blocking block 20 to move forward and backward. At this time, the staff should pull the spring rod 23 in time to pull the blocking block 20 out of the opening 22, and then rotate the spring rod 23 to drive the blocking block 20 to rotate, so that the blocking block 20 no longer blocks the opening 22, and then pull the guide plate 15 and the second screening net 151 out of the opening 22, clean the second screening net 151, and the guide plate 15 is in contact with the spring rod 19, so as to facilitate the removal or placement of the guide plate 15 from the spring rod 19;

[0043] The mineral solid waste that does not reach the crushed particle size flows to the discharge port 1 24 through the left and right sides of the screening net 151, and flows into the sampling slot 25 through the discharge port 1 24. The mineral solid waste that does not reach the crushed particle size can be taken out through the discharge port 3 26, and the sampling slot 25 can also be sealed. The specific steps are to seal the upper end of the sampling slot 25, the discharge port 1 24 and the discharge port 3 26, so that the mineral solid waste in the sampling slot 25 is allowed to stand and volatilize, and then the volatile organic compounds (VOCs) in the sampling slot 25 are detected, and the VOCs in the waste are detected by gas chromatography to evaluate its impact on the air quality. The metal material can flow to the discharge port 2 27 through the left and right sides of the guide plate 15, and the discharge port 2 27 flows into the sampling slot 2 28. The metal material can be taken out through the discharge port 4 29, and the specific composition of the metal material is detected and analyzed.

At this time, the cleaned mineral solid waste falls into the lower side of the working hole 50, and the sliding block 48 moves to the upper end of the sliding hole 47 and slides The block 48 cannot move, the threaded rod 45 cannot move upward, and the bottom block 53 cannot continue to move upward. At this time, the blocking plate 52 just rotates to the vertical state, and the threaded rod 45 and the threaded sleeve 43 begin to rotate synchronously. When the threaded rod 45 rotates, it drives the screening cylinder 34 to rotate through the bottom block 53. Since the fixed sleeve 44 is fixedly arranged and the plurality of stirring blades 49 are fixedly arranged, the mineral solid waste in the working hole 50 rotates with the screening cylinder 34. At this time, the mineral solid waste and the stirring blades 49 are in a relative rotation state. At this time, water is re-added to the working hole 50, and the stirring blades 49 stir the mineral solid waste to dissolve the mineral solid waste. The dissolved solution flows to the sampling cavity through the left and right sides of the liquid guide plate 36 and the liquid inlet. 37, flows to the outside through the liquid outlet 38, and the components and Ph value of the dissolved liquid are detected and analyzed. A material taking port is set at the lower end of the detection shell 1 and the lower end of the screening cylinder 34, and the precipitate is taken out through the material taking port and its components are detected and analyzed. When the working mechanism is working, a blocking block is set in the material taking port at the lower end of the screening cylinder 34. The detection and analysis of the components in the cleaning liquid, the detection and analysis of the components of the dissolved liquid, and the detection and analysis of the components of the precipitate all adopt the existing chemical analysis method, wherein the precipitate can be dried before detection, and the Ph value of the cleaning liquid and the dissolved liquid can also be detected by using a Ph meter. The above-mentioned chemical analysis method and the detection of the Ph value all use the existing technology, and the present invention will not repeat them.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
