The filter components 5 can introduce slag into the inside of the second sleeve 14, and a driving component 4 for driving the second sleeve 14 to rotate is provided inside the inner sleeve 13;

[0039] The inner wall of the filter box 2 is vertically slidably connected with a No. 2 filter plate 17, the No. 2 filter plate 17 is sleeved on the outside of the No. 2 sleeve 14, a No. 2 spring 18 is connected between the No. 2 filter plate 17 and the boss outside the No. 2 sleeve 14, a No. 3 spring 19 is arranged between the No. 2 filter plate 17 and the end seat on the inner wall of the filter box 2, and an adjustment component 6 for pushing the No. 2 filter plate 17 to rise and fall vertically is fixedly arranged on the inner wall of the filter box 2, the No. 2 filter plate 17 is fixedly connected with an upper toothed disc 21, the elastic telescopic sleeve 16 is fixedly connected with a lower toothed disc 22, the elastic telescopic sleeve 16 is meshed with the No. 2 filter plate 17, the filter box 2 is connected with a pump 9, and the water suction pipe of the pump 9 is connected to the upper part of the No. 2 filter plate 17;

[0040] The inner sleeve 13 is provided with a plurality of orifice plates 20 slidably connected to the end surface inside the filter box 2, and the orifice plates 20 are elastically connected to the side walls of the filter box 2. The elastic telescopic sleeve 16 is connected to a brush strip 7, and the brush strip 7 can dredge the orifice plates 20. A guide assembly 8 that can drive the orifice plates 20 to vibrate is provided between the brush strip 7 and the orifice plates 20;

[0041] A plurality of No. 1 sleeves 10 are fixedly provided on the outer end surface of the filter box 2, each of which is provided with a first spiral pushing assembly 11 for vertically pushing the slag, and each of the No. 1 sleeves 10 is connected to the interior of the filter box 2, and a filter screen 12 is provided on the end surface where the No. 1 sleeve 10 is connected to the filter box 2.

[0042] The control system can control the filtering efficiency of the slurry by controlling the adjustment component 6 , the first spiral push component 11 , and the second spiral push component 15 .

[0043] In this embodiment, when the slurry enters the crushing cylinder 1, the ore with a larger volume is crushed by the crushing mechanism 3, and then the crushed ore enters the filter box 2 with the slurry. At this time, under the guidance of the inner sleeve 13, the ore with a larger volume is dispersed to the four sides of the filter box 2, and then discharged to the outside of the filter box 2 through the second spiral pusher assembly 15, and the slag with a smaller volume is separated from the first spiral pusher assembly 11 through the filter screen 12 and dispersed around the inner sleeve 13;

[0044] The slag with a smaller volume is mixed in the ore pulp, and the driving component 4 drives the elastic telescopic sleeve 16 to rotate, and the elastic telescopic sleeve 16 drives all the filter components 5 to rotate, and the slag is filtered and collected by the filter components 5. Then, under the guidance of the filter components 5, the slag enters the second sleeve 14, and this part of the slag is collected and transmitted to the outside of the filter box 2 by the second spiral pusher component 15. The second sleeve 14 can be connected to the hose to guide the slag out;

[0045] When there is too much slag accumulated in the filter box 2, the slag enters the inner sleeve 13 from the orifice plate 20. Under the guidance of the inner sleeve 13, the second spiral pusher assembly 15 transports the slag accumulated in the inner sleeve 13 to the outside of the filter box 2. The elastic telescopic sleeve 16 drives the brush bar 7 to clean the orifice plate 20 at the same time, thereby avoiding clogging of the orifice plate 20. When there is too much slag accumulated on the periphery of the inner sleeve 13, the slag squeezes the orifice plate 20, and the orifice plate 20 approaches the brush bar 7 on the inside. At this time, driven by the brush bar 7, the guide assembly 8 pushes the orifice plate 20 to vibrate, thereby accelerating the screening effect of the orifice plate 20 and accelerating the collection of smaller slag into the inner sleeve 13.

[0046] The first spiral pusher assembly 11 and the inner sleeve 13 can transport slag of different weights respectively. Then, under the filtering action of the second filter plate 17, the water in the slurry is pumped out to the outside of the filter box 2 through the pump 9 for secondary utilization.

[0047] like Figure 5 As shown, a thickener anti-sedimentation fine filtration system provided by the present invention is provided, wherein the filter assembly 5 comprises a first filter plate 51, a guide groove 52, a mesh plate 53 and a guide plate 54;

[0048] The end face of one side of the filter plate No. 1 51 perpendicular to the horizontal plane is provided with a plurality of guide grooves 52, and the opening of the guide grooves 52 is arranged in a V shape toward the outside of the filter plate No. 1 51, and the other end face of the filter plate No. 1 51 facing the guide grooves 52 is provided with a mesh plate 53, and a plurality of guide plates 54 are arranged on this end face, and one end of the filter plate No. 1 51 is connected to the through hole on the sleeve No. 2 14.

[0049] In this embodiment, when the elastic telescopic sleeve 16 drives the No. 1 filter plate 51 to rotate, under the guidance of the guide groove 52, the slurry flows into the No. 1 filter plate 51. At this time, the slag in the slurry is retained in the No. 1 filter plate 51 under the filtration of the mesh plate 53. At the same time, under the guidance of the mesh plate 53, the slag enters the No. 2 sleeve 14. The second spiral pushing assembly 15 in the No. 2 sleeve 14 can transport the slag with smaller weight in the slurry outward. When the elastic telescopic sleeve 16 rotates, the elastic telescopic sleeve 16 drives the lower toothed disc 22 to rotate relative to the upper toothed disc 21. Under the reverse thrust of the upper toothed disc 21, the lower toothed disc 22 drives the telescopic end of the elastic telescopic sleeve 16 to vibrate vertically. The elastic telescopic sleeve 16 drives all the No. 1 filter plates 51 to vibrate vertically, thereby avoiding the blockage of the mesh plate 53 while accelerating the slag in the No. 1 filter plate 51 to enter the No. 2 sleeve 14.

[0050] like Figure 4 As shown, a thickener anti-sedimentation fine filtration system provided by the present invention is provided, wherein the adjustment assembly 6 comprises a guide rod 61, an electric telescopic sleeve 62 and a No. 1 spring 63;

[0051] The inner wall of the filter box 2 is fixedly connected with a guide rod 61, and the guide rod 61 slides and penetrates the second filter plate 17. The guide rod 61 is fixedly connected with a retractable electric telescopic sleeve 62, and a first spring 63 is arranged between the electric telescopic sleeve 62 and the second filter plate 17.

[0052] The electric telescopic sleeve 62 is started to extend, and the electric telescopic sleeve 62 pushes the No. 1 spring 63. The No. 1 spring 63 squeezes the No. 2 filter plate 17 to move downward, and the No. 2 filter plate 17 drives the upper toothed disc 21 to contact the lower toothed disc 22. The lower toothed disc 22 rotates with the elastic telescopic sleeve 16. Under the thrust of the lower toothed disc 22, the No. 2 filter plate 17 vertically reciprocates to avoid clogging of the No. 2 filter plate 17, resulting in reduced water filtration efficiency in the slurry, and the water in the slurry cannot be pumped out through the pump 9.

[0053] like Figure 8 As shown, a thickener anti-sedimentation fine filtration system provided by the present invention is provided, wherein the guide assembly 8 comprises a push block 81 and a rack 82 , wherein the push block 81 is fixedly connected to the brush bar 7 , and the end surface of the orifice plate 20 facing the brush bar 7 is provided with a rack 82 .

[0054] In this embodiment, when too much slag is accumulated around the inner sleeve 13, the slag squeezes the orifice plate 20, and the orifice plate 20 approaches the inner brush bar 7. At this time, driven by the brush bar 7, the push block 81 collides with the rack 82, and the rack 82 pushes the orifice plate 20 to vibrate, thereby accelerating the screening effect of the orifice plate 20 and accelerating the collection of smaller slag into the inner sleeve 13.

[0055] like Figure 8 As shown, a thickener anti-sedimentation fine filtration system provided by the present invention is provided, wherein the driving assembly 4 includes a No. 2 motor 41 and a gear transmission pair 42, wherein the No. 2 motor 41 is fixedly connected to the inner sleeve 13, and a gear transmission pair 42 is arranged between the output shaft of the No. 2 motor 41 and the elastic telescopic sleeve 16.

[0056] In this embodiment, the second motor 41 is started, and the second motor 41 drives the elastic telescopic sleeve 16 to rotate through the gear transmission pair 42 .

[0057] like Figure 2 As shown, a thickener anti-sedimentation fine filtration system provided by the present invention is provided, wherein the pulverizing mechanism 3 includes a first motor 31, a rotating shaft 32 and a stirring rod 33;

[0058] The first motor 31 is fixedly connected to the grinding cylinder 1 , the output shaft of the first motor 31 is fixedly connected to the rotating shaft 32 , and the rotating shaft 32 is fixedly connected to the stirring rod 33 .

[0059] In this embodiment, the first motor 31 is started, the first motor 31 drives the rotating shaft 32 to rotate, and the rotating shaft 32 drives the stirring rod 33 to rotate, so as to crush the ore in the ore pulp.

[0060] like Figure 1 As shown, a thickener anti-sedimentation fine filtration system provided by the present invention is provided, wherein the lower portion of the brush bar 7 can be fixedly connected to a scraper, and the scraper scrapes off the slag on the side wall of the inner sleeve 13, thereby accelerating the external transportation of the slag.

[0061] The present invention provides a thickener anti-sedimentation fine filtration system, wherein the control system comprises:

[0062] A pressure detection module, which includes a first pressure sensor and a second pressure sensor, wherein the first pressure sensor is disposed between the boss of the second sleeve 14 and the second spring 18, and the second pressure sensor is disposed on the end surface of the mesh plate 53;

[0063] A processing module, which is used to compare the pressure values ​​obtained by the first pressure sensor and the second pressure sensor with a preset threshold value in the processing module and form judgment information;

[0064] The control module is used to control the adjustment component 6 , the first spiral pusher component 11 and the second spiral pusher component 15 .

[0065] In this embodiment, when the pressure value of the No. 1 pressure sensor exceeds the preset threshold value in the processing module, it means that the No. 2 filter plate 17 is subjected to a large buoyancy and the filter holes on the No. 2 filter plate 17 are blocked. At this time, the control module controls the electric telescopic sleeve 62 to start, and the electric telescopic sleeve 62 pushes the No. 1 spring 63 to contract, and the No. 1 spring 63 drives the No. 2 filter plate 17 to move downward, so that the upper toothed disc 21 on the No. 2 filter plate 17 contacts the lower toothed disc 22 on the elastic telescopic sleeve 16, and the lower toothed disc 22 is driven to rotate by the elastic telescopic sleeve 16, and the lower toothed disc 22 drives the No. 2 filter plate 17 to vibrate vertically, so that the slag attached to the No. 2 filter plate 17 falls off, thereby improving the filtering effect of the slurry;

[0066] When the pressure value of the No. 2 pressure sensor exceeds the preset threshold value in the processing module, it means that the mesh plate 53 is blocked. At this time, the control module controls the electric telescopic sleeve 62 to push the No. 1 spring 63 to be compressed to the extreme. At this time, the No. 1 spring 63 and the No. 3 spring 19 are both compressed to the extreme. At this time, the No. 2 filter plate 17 and the upper toothed disc 21 on the No. 2 filter plate 17 are fixed. Under the guiding action of the upper toothed disc 21, the lower toothed disc 22 pushes the elastic telescopic sleeve 16 to vibrate vertically, and the vibration force of the elastic telescopic sleeve 16 reaches the maximum. The elastic telescopic sleeve 16 drives all the filter components 5 to vibrate, thereby accelerating the slag in the No. 1 filter plate 51 to enter the No. 2 sleeve 14. At the same time, the control module controls the No. 2 sleeve 14 and the second spiral pushing assembly 15 to increase the conveying rate, further improve the slag extraction rate in the filter box 2, improve the filtration efficiency of the slurry, and allow the moisture in the slurry to be reused for a second time.

[0067] In the present invention, the first spiral pusher assembly 11 transports the heavier slag that sinks in the water to the outside, and at the same time, the filter assembly 5 collects the lighter slag suspended in the water and transports it through the second spiral pusher assembly 15; further, the filter screen 12 discharges the smaller slag mixed in the first spiral pusher assembly 11, and collects the smaller part of the slag into the inner sleeve 13 through the orifice plate 20, and the second spiral pusher assembly 15 transports this part to the outside; through the cooperation of the above-mentioned mechanisms, the larger and heavier slag in the slurry can be sent out through the first spiral pusher assembly 11, and the smaller and lighter slag in the slurry can be output through the second spiral pusher assembly 15, thereby improving the screening effect of the slag, and at the same time, the slag in the slurry can be quickly collected and output, so that the moisture in the slurry can be filtered and can be used again;

[0068] The control system can provide feedback to the control module based on the resistance of the second filter plate 17 and the filter assembly 5, thereby adjusting and controlling the adjustment assembly 6, the first spiral pusher assembly 11 and the second spiral pusher assembly 15 to improve the screening and filtering effect of slag and water in the slurry.
