[0026] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0027] Embodiment 1

[0028] like Figures 1 to 6 As shown, a multi-stage grinding and crushing system for bentonite comprises an outer frame (1), a reaction kettle (2) arranged at the lower end of the outer frame (1), and a driving member (3); a transmission assembly (4) driven by the driving member (3) is arranged in the outer frame (1); a grinding assembly a (5) is arranged on the transmission assembly (4); a feeding assembly (6) is arranged in the middle of the transmission assembly (4); a grinding assembly b (7) is arranged at the lower end of the feeding assembly (6); grinding blocks (8) are arranged on both left and right sides of the outer frame (1); a grinding groove a (81) is provided in the grinding block (8); and a grinding groove a (81) is arranged at the lower end of the outer frame (1). A truncated table (9) is provided in which a grinding trough b (91) is formed. A material pipe (10) is provided at the lower end of the grinding block (8). A mixing component (20) is provided in the reactor (2). The feeding component (6) is driven by the transmission component (4) to deliver bentonite to the grinding trough a (81). The bentonite is firstly ground by the grinding component a (5). The bentonite is delivered to the grinding trough b (91) through the material pipe (10). The bentonite is secondarily ground by the grinding component b (7). The bentonite and the reaction liquid introduced into the reactor (2) are mixed by the mixing component (20) to modify the bentonite to sodium.

[0029] It is worth mentioning that a grinding assembly a (5) is arranged on the transmission assembly (4), and a grinding assembly b (7) is arranged at the lower end of the feeding assembly (6). The feeding assembly (6) is driven by the transmission assembly (4) to deliver bentonite to the grinding trough a (81), the bentonite is initially ground by the grinding assembly a (5), the bentonite is delivered to the grinding trough b (91) through the material pipe (10), the bentonite is secondarily ground by the grinding assembly b (7), and the bentonite and the reaction liquid introduced into the reaction kettle (2) are mixed by the mixing assembly (20) to sodium-modify the bentonite, which is beneficial to multi-stage crushing of the bentonite and makes it crushed more thoroughly.

[0030] like Figure 2 As shown, the transmission assembly (4) includes a transmission member a (41) driven by a driving member (3) and a transmission member b (42) rotatably arranged at the other end of the loading assembly (6), and the front ends of the transmission member a (41) and the transmission member b (42) are both arranged to be inclined at an angle of 10 degrees to the side wall of the outer frame (1).

[0031] In this example, the front ends of the transmission member a (41) and the transmission member b (42) are arranged to be inclined at an angle of 10 degrees to the side wall of the outer frame (1), so that the loading assembly (6) can swing in multiple directions under the drive of the transmission member a (41) and the transmission member b (42).

[0032] like Figure 3 As shown, the grinding assembly a (5) includes a support rod (51) arranged at the front end of the transmission member a (41) and a grinding ball a (52) arranged at the front end of the support rod (51), and the support rod (51) is arranged parallel to the side wall of the outer frame (1).

[0033] In this example, the support rod (51) is arranged parallel to the side wall of the outer frame (1), so that the grinding ball a (52) can rotate in a circumferential direction to perform initial grinding on the bentonite in the grinding groove a (81).

[0034] like Figure 2 , Figure 5 As shown, the loading assembly (6) includes a loading box (61) arranged between the transmission member a (41) and the transmission member b (42) and a partition plate (62) arranged in the loading box (61), wherein the partition plate (62) divides the loading box (61) into a material bin a (611) and a material bin b (612), and an inclined surface is arranged at the upper end of the partition plate (62), and a discharge port a (613) is provided on the side of the material bin a (611) and the material bin b (612) close to the transmission member.

[0035] In this example, a slope is provided on the upper end of the partition plate (62) so that the bentonite can fall evenly into the silo a (611) and the silo b (612) without being accumulated on the partition plate (62), and the bentonite is discharged through the discharge port a (613).

[0036] like Figure 3 As shown, the grinding assembly b (7) includes a support block (71) arranged at the lower end of the loading box (61), a grinding rod (72) arranged at the lower end of the support block (71), and a grinding ball b (73) arranged at the lower end of the grinding rod (72).

[0037] like Figure 2 As shown, the mixing assembly (20) comprises a motor (201), a rotating shaft (202) driven by the motor (201), and a stirring blade (203) arranged at the upper end of the rotating shaft (202).

[0038] like Figure 2 , Figure 4 As shown, a baffle (82) is provided on the grinding block (8), and a plurality of filter holes a (83) are provided in the grinding groove a (81).

[0039] In this example, the bentonite falling from the discharge port a (613) is blocked by the baffle (82) to prevent it from falling into the outer frame (1).

[0040] like Figure 4 As shown, a plurality of filter holes b (92) are provided in the grinding tank b (91), and the diameter of the filter holes b (92) is smaller than that of the filter holes a (83).

[0041] In this example, the bentonite particles become smaller after secondary grinding, so the diameter of the filter hole b (92) is smaller than that of the filter hole a (83), so that the particles meet the requirements and fall into the reactor (2) for sodium modification.

[0042] like Figure 1 , Figure 4 As shown, a feed pipe (30) is provided at the left end of the reaction kettle (2), and a discharge port b (40) is provided at the right end of the reaction kettle (2).

[0043] In this example, the sodium-modified bentonite is taken out through the discharge port b (40).

[0044] The working process is as follows:

[0045] The driving member 3 is started, and the driving member 3 drives the transmission member a41 to rotate, thereby driving the loading box 61 to swing in multiple directions, and the conveyor belt delivers the bentonite to the loading box 61, and the bentonite falls evenly into the silo a611 and the silo b612 through the partition plate 62. The loading box 61 swings in multiple directions, so that the bentonite in the silo a611 and the silo b612 falls from the discharge port a613 in sequence;

[0046] The bentonite falls into the grinding grooves a81 on the left and right sides in turn, and the grinding balls a52 are driven to rotate in a circumferential direction by the transmission parts a41 and b42, so as to grind the bentonite in the grinding groove a81 for the first time. The crushed bentonite falls into the material pipe 10 through the filter hole a83, and is then sent to the grinding groove b91 through the material pipe 10.

[0047] The multi-directional swing of the feeding box 61 drives the grinding balls b73 to make circular motion in the grinding groove b91, and the bentonite is grinded for the second time. The crushed bentonite falls into the reactor 2 through the filter hole b92, and the atomized reaction liquid is sprayed into the feed pipe 30. The motor 201 drives the rotating shaft 202 to rotate, and drives the stirring blades 203 to rotate, so that the bentonite is mixed and stirred, and the bentonite is sodium-modified. The sodium-modified bentonite is taken out through the discharge port b40.

[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art under the technical guidance of the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
