[0002] Attapulgite, also known as palygorskite or palygorskite clay, is a hydrous magnesium aluminum silicate clay mineral with a chain-like layered structure.

[0053] The specific application of this embodiment is: when the whole device is used for preliminary grinding of the attapulgite clay to be ground and purified, the two roller grooves 102 opened at the bottom of the convex downward moving box 101 and the moving wheels 103 rotatingly matched inside the two roller grooves 102 reciprocatingly roll inside the two moving grooves 302, repeatedly extruding the arc-shaped convex blocks 402 respectively and slidingly matched inside the two rectangular grooves 303, so that the elastic springs 404 connected and fixed between the displacement plates 403 and the cross beam plates 301 are repeatedly stretched and extruded on the circumferential side of the vertical rods 305, thereby driving the sliding plates 401 and the two displacement plates 403 to reciprocatingly move up and down on the circumferential side of the rectangular frame 304 and the two vertical rods 305, so that the slide bar 406 fixed inside the rotating groove 405 repeatedly moves up and down on the U-shaped slide plate 501 in the raised part 5, thereby driving the rotating cylinder 502 fixed on the outer side of the U-shaped slide plate 501 to repeatedly rise and press down on the circumferential side of the rotating shaft 307, so that the several extension rods 503 fixed on the circumferential side of the rotating cylinder 502 and the knocking balls 504 fixed at the end of the several extension rods 503 repeatedly and intermittently contact with the lower surface of the purification screening net 104, thereby intermittently and reciprocatingly knocking the purification screening net 104, avoiding that the preliminary ground and purified attapulgite clay debris is too large to be blocked in the purification screening net 104, affecting the later screening process, and improving the later grinding and purification effect.

[0054] Embodiment two, please refer to Figures 1-12The embodiment two is improved on the basis of the embodiment one, specifically, the first limiting nut is threadedly connected to the bottom of the vertical rod 305; the U-shaped vertical frame 308 is fixed to the top of the oblique guide frame 306, a horizontal guide slot 309 is formed in one outer side of the U-shaped vertical frame 308; the guide sliding block 105 is fixed to one outer side of the inverted convex mobile box 101 and slidably arranged in the horizontal guide slot 309; the rotating shaft 106 is fixed to the center of one side of the guide sliding block 105, the rotating disc 107 is rotatably connected to the rotating shaft 106, the first pin shaft 108 is fixed to the center of one end of the rotating disc 107, the threaded column 109 is fixed to one end of the first pin shaft 108, and the second limiting nut is threadedly connected to one end of the threaded column 109; the U-shaped support plate 310 is fixed to one outer side of the U-shaped vertical frame 308, the first motor 311 is fixed to one outer side of the U-shaped support plate 310, the main rotating disc 312 is fixed to the output shaft of the first motor 311, the second pin shaft 313 is fixed to the eccentric position of one end of the main rotating disc 312, the third limiting nut is threadedly connected to one end of the second pin shaft 313, the reciprocating arm 314 is rotatably connected to the circumferential surface of the second pin shaft 313, and the rotation of the main rotating disc 312 drives the reciprocating arm 314 to periodically swing, so as to drive the guide sliding block 105 to horizontally reciprocate, the pin shaft hole 315 is formed in one side of the reciprocating arm 314 and rotatably connected with the first pin shaft 108; the L-shaped support plate 316 is fixed to one outer side of the U-shaped vertical frame 308, and the mounting plate 317 is fixed to the bottom of the L-shaped support plate 316; the feeding hopper 110 is communicated with the outer top of the inverted convex mobile box 101, the two second motors 111 are fixed to one side of the outer side of the inverted convex mobile box 101 below the feeding hopper 110, the output shafts of the two second motors 111 are both extended inwardly through one outer side of the inverted convex mobile box 101 and rotatably connected with the one outer side of the inverted convex mobile box 101, and the grinding rollers 112 are fixed to the output shafts of the two second motors 111 in the inverted convex mobile box 101; the oblique plates 113 are fixed to the inner side walls of the feeding hopper 110 above the grinding rollers 112, and the arc-shaped scraping plates 114 are fixed to the bottoms of the oblique plates 113 and matched with the grinding rollers 112.

[0055] The specific application of the second embodiment is that during use, the mounting plate 317 is first positioned on one side of the subsequent purification equipment through the external bolt, so that the discharge end of the inclined guide frame 306 is located above the feed inlet of the subsequent purification equipment, so that after grinding before purification, subsequent purification operation can be carried out. Before the purification operation, the attapulgite clay to be ground and purified is mined and enters the inside of the feed hopper 110 through the conveyor at this time. At the same time, the two second motors 111 are started to drive the two grinding rollers 112 fixed on the output shafts of the two second motors 111 to rotate towards each other in the inverted convex moving box 101 (the two grinding rollers 112 rotate towards each other in the inverted convex moving box 101: one rotates clockwise and the other rotates counterclockwise, the rotation of the two second motors 111 is controlled by the controller). The attapulgite clay to be ground and purified falling into the inside of the feed hopper 110 is subjected to preliminary grinding operation. After the grinding operation is completed, the ground attapulgite clay to be ground and purified enters the inside of the inverted convex moving box 101 for preliminary filtration after grinding, so as to facilitate subsequent purification operation. While the two grinding rollers 112 rotate towards each other in the inverted convex moving box 101, the arc-shaped scrapers 114 fixed on the bottoms of the two inclined plates 113 and the two grinding rollers 112 are matched with each other to scrape off the attapulgite clay to be ground and purified adhering to the surfaces of the two grinding rollers 112, so as to avoid affecting the subsequent continuous grinding and crushing process.

At the same time, the reciprocating movement of the inverted convex moving box 101 and the attapulgite clay to be ground and purified after preliminary grinding on the two beam plates 301 can further improve the purification and screening effect after preliminary grinding.
