Description

Technical Field

[0001] The present application relates to the technical field of grinding equipment, and in particular to a lithium carbonate grinding device. Background Art

[0002] Lithium carbonate is generally used as a raw material for ceramics, glass, ferrite, etc., and during its preparation, a grinding device is usually required to grind small pieces of lithium ore into powder, and the powder is processed to obtain the required lithium carbonate.

[0003] Some existing grinding devices are mainly composed of a collecting cylinder, a rotating shaft and a grinding roller. When in use, small pieces of lithium ore are placed in the collecting cylinder. Then, the rotating shaft drives the symmetrically arranged grinding rollers to revolve in the collecting cylinder. In this process, the revolving grinding rollers gradually contact and squeeze the lithium ore at the bottom of the collecting cylinder, and rotate on their own, so that the lithium ore gradually becomes powder. Through the above actions, the grinding operation of the lithium ore is completed.

[0004] However, in the above process, since the bottom of the collecting cylinder is flat and the grinding roller is a drum, when the grinding roller contacts the lithium ore on the plane, part of the lithium ore will be pushed by the rotating grinding roller instead of entering between the grinding roller and the bottom wall of the collecting cylinder, which makes the grinding roller need to work longer to grind all the lithium ore into powder. As a result, the grinding efficiency of the lithium ore is affected. Summary of the invention

[0005] The present application proposes a lithium carbonate grinding device, which has the advantage of increasing the probability of small pieces of lithium ore entering the working area, and is used to solve the problem that part of the lithium ore is pushed away by the grinding roller, resulting in the grinding efficiency of the lithium ore being affected.

[0007] Furthermore, the slider forms a sealed sliding connection with the slide groove, a main cavity is opened inside the collecting tube and below the slide groove, a through hole is opened inside the collecting tube and between the slide groove and the main cavity, and the through hole connects the corresponding slide groove and the main cavity.

[0008] Furthermore, a shielding cover is fixedly installed above the collecting tube to form a closed cavity in cooperation with the collecting tube.

[0009] Furthermore, a card slot is provided at the center position inside the slider, and the opening of the card slot is provided on the bottom surface of the slider. A card rod is slidably installed inside the card slot, and the lower end of the card rod passes through the through hole and extends into the main cavity. A fixing rod is fixedly installed inside the main cavity, and the lower end of the card rod is connected to the fixing rod.

[0010] Furthermore, the lower end of the clamping rod is fixedly connected to the fixing rod.

[0011] Furthermore, the lower end of the clamping rod passes through the fixed rod, and the part of the clamping rod passing through the fixed rod is rotatably connected with the fixed rod. The cavity of the clamping slot and the cross-section of the clamping rod are both square. A rotating part is rotatably installed on the bottom surface of the slider and located at the outer side of the clamping slot. The upper end of the spring is fixedly connected with the rotating part. A contact part is fixedly installed on the lower end of the clamping rod. A turntable is provided in the cavity of the total cavity and located below the fixed rod. The rotating shaft of the turntable is fixedly connected with the output shaft of the second motor. A vertical ring is fixedly installed on the upper side surface of the turntable and corresponds to the inner side of the contact part, and the contact part is driven to rotate by the rotation of the vertical ring.

[0012] Furthermore, the outer side of the contact piece and the outer side of the vertical ring are both rubber layers, and the outer side of the contact piece contacts the outer side of the vertical ring.

[0013] Furthermore, gear teeth are fixedly installed at circumferentially equal intervals on the outer sides of the contact piece and the vertical ring, and the contact piece and the vertical ring form a meshing connection.

[0014] This application has the following beneficial effects:

[0015] The present application provides a lithium carbonate grinding device, which, through the setting of a spring and a slider, utilizes the spring to drive the slider to protrude from the bottom wall of the collecting cylinder, so that during the revolution of the grinding roller, part of the lithium ore pushed by the grinding roller will be blocked by the slider and then retained between the slider and the grinding roller, and in the subsequent process, it will be squeezed and ground by the grinding roller. Through the above-mentioned actions, the grinding efficiency of the lithium ore is improved.

[0016] Through the setting of the spring and the slider, during the process of the grinding roller extruding and grinding the lithium ore, the slider is synchronously squeezed and moved downward.

[0017] By setting the clamping rod and the slider, the clamping rod is used to drive the slider to rotate, so that when the slider is pressed downward by the grinding roller, the lithium ore between the two will be subjected to the grinding force applied by the rotating slider, thereby further reducing the particle size of the lithium ore and further accelerating the grinding efficiency of the lithium ore.

[0018] Through the setting of the clamping rod and the slider, the clamping rod drives the slider to rotate, so that after the grinding roller leaves the slider, the slider that moves up and resets continues to rotate. Through this action, the particles in contact with the slider are further prompted to leave the current position and stack with the particles in the remaining positions, so that when the subsequent grinding roller contacts this part of the particles again, the extrusion and grinding effect of this part of the particles is improved.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] Example 1: Please refer to Figure 1-Figure 6 A lithium carbonate grinding device comprises a collecting cylinder 1, wherein grinding rollers 2 are symmetrically arranged in the cavity of the collecting cylinder 1, a horizontal axis 3 is arranged between the two grinding rollers 2, and one end of the horizontal axis 3 corresponding to the grinding roller 2 is rotatably connected with the center position of the side of the grinding roller 2, a vertical axis 4 is fixedly installed in the middle position of the horizontal axis 3, the upper end of the vertical axis 4 extends out of the collecting cylinder 1, and the upper end of the vertical axis 4 is fixedly connected to the output end of a No. 1 motor (existing technology, not shown in the figure), and a slide groove 5 is equidistantly provided in the interior of the collecting cylinder 1 and below the grinding roller 2. The opening of the slide groove 5 is provided on the bottom inner wall of the collecting cylinder 1, and a slider 6 is slidably installed in the slide groove 5, and the upper part of the slider 6 extends out of the slide groove 5, and a spring 7 is arranged in the interior of the slide groove 5 and below the slider 6, the upper end of the spring 7 is connected to the slider 6, and the lower end of the spring 7 is fixedly connected to the bottom wall of the slide groove 5.

[0030] When in use, small pieces of lithium ore are put into the collecting cylinder 1, and then the No. 1 motor drives the vertical shaft 4 to rotate, so that the horizontal shaft 3 drives the symmetrically arranged grinding rollers 2 to revolve in the collecting cylinder 1, and then the revolving grinding rollers 2 gradually contact and squeeze the lithium ore at the bottom of the collecting cylinder 1, and rotate, so that the lithium ore is gradually powdered. At the same time, during the revolution of the grinding roller 2, part of the lithium ore pushed by the grinding roller 2 will be blocked by the slider 6 protruding from the bottom wall of the collecting cylinder 1, and then retained between the slider 6 and the grinding roller 2, and in the subsequent process, it is squeezed and ground by the grinding roller 2. Through the above actions, the grinding efficiency of the lithium ore is improved. In addition, during the process of the grinding roller 2 squeezing and grinding the lithium ore, the slider 6 is synchronously squeezed and moved downward, and the corresponding spring 7 is compressed. Afterwards, when the grinding roller 2 leaves the slider 6, the spring 7 releases the elastic force and drives the corresponding slider 6 to move upward Reset, at this time, the upward slider 6 will push the powder particles above (the lithium ore will be around and above the slider 6, so that when the lithium ore and the slider 6 are squeezed by the grinding roller 2 later, part of the lithium ore above the slider 6 is crushed and ground into powder or particles, and part of the powder and particles are still above the slider 6), prompting the particle to leave the current position (the particle is subjected to two forces, one is the force exerted by the powder and particles above the slider 6 when the spring 7 overcomes the connection between the powder particle layers, so that the upward slider 6 drives the powder and particles above to separate from the powder and particles on the bottom wall of the collecting cylinder 1, and the other is the vibration force generated by the contact between the upward slider 6 and the gradually moving away grinding roller 2), and stack with the particles in the remaining positions, so that when the subsequent grinding roller 2 contacts this part of the particles again, the extrusion and grinding effect of this part of the particles is improved.

[0031] See also Figure 1-Figure 6 The slider 6 forms a sealed sliding connection with the slide groove 5, a total cavity 8 is opened inside the collecting cylinder 1 and below the slide groove 5, a through hole 9 is opened inside the collecting cylinder 1 and between the slide groove 5 and the total cavity 8, the through hole 9 connects the corresponding slide groove 5 with the total cavity 8, and a shielding cover 10 is fixedly installed above the collecting cylinder 1 to cooperate with the collecting cylinder 1 to form a closed cavity.

[0032] When some sliders 6 are squeezed and moved downward by the grinding roller 2, the air in the corresponding chute 5 will pass through the through hole 9 and the main cavity 8, and then be transmitted to the remaining chute 5, and drive the sliders 6 at the remaining positions to move further upward. Through this action, the degree of blocking of lithium ore by the remaining sliders 6 is improved, which promotes the simultaneous improvement of the grinding efficiency of lithium ore. At the same time, the shielding cover 10 is used to block the flying powder to avoid waste.

[0033] Example 2: Please refer to Figure 1-Figure 6This embodiment is a further improvement of the first embodiment, and the improvement lies in that: a card slot 11 is opened at the center position inside the slider 6, and the opening of the card slot 11 is opened on the bottom surface of the slider 6. A card rod 12 is slidably installed inside the card slot 11, and the lower end of the card rod 12 passes through the through hole 9 and extends into the main cavity 8. A fixing rod 13 is fixedly installed inside the main cavity 8, and the lower end of the card rod 12 is connected to the fixing rod 13.

[0034] By setting the clamping rod 12, when the slider 6 is squeezed and moves downward, its upper surface moves downward to a position overlapping with the bottom wall of the collecting cylinder 1, and will be blocked by the clamping rod 12, thereby preventing the slider 6 from moving downward excessively and affecting the grinding efficiency of the lithium ore.

[0035] See also Figure 1-Figure 6 The cross-sections of the cavity of the card slot 11 and the card rod 12 are both square. A rotating member 14 is rotatably installed on the bottom surface of the slider 6 and located outside the card slot 11. The upper end of the spring 7 is fixedly connected to the rotating member 14. The lower end of the card rod 12 passes through the fixed rod 13. The part of the card rod 12 passing through the fixed rod 13 is rotatably connected to the fixed rod 13. A contact member 15 is fixedly installed at the lower end of the card rod 12. A rotating disk 16 is arranged in the cavity of the total cavity 8 and located below the fixed rod 13. The rotating shaft of the rotating disk 16 extends out of the collecting cylinder 1 and is connected to the collecting cylinder 1. The output shaft of the No. 2 motor (existing technology, not shown in the figure) is fixedly connected, and a vertical ring 17 is fixedly installed on the upper side of the turntable 16 and corresponds to the inner position of the contact piece 15. The outer side of the contact piece 15 and the outer side of the vertical ring 17 are both rubber layers, and the outer side of the contact piece 15 is in contact with the outer side of the vertical ring 17 (the outer side of the contact piece 15 and the outer side of the vertical ring 17 can be fixedly installed with gear teeth at equal intervals in the circumferential direction, not shown in the figure, so that the contact piece 15 and the vertical ring 17 form a meshing connection. This configuration replaces the rubber layer of the contact piece 15 and the vertical ring 17).

[0036] During the operation of the grinding roller 2, the No. 2 motor drives the turntable 16 and the vertical ring 17 to rotate. Through the force between the vertical ring 17 and the contact piece 15, the contact piece 15 drives the clamping rod 12 and the slider 6 to rotate synchronously. Afterwards, when the slider 6 is pressed downward by the grinding roller 2, the lithium ore between the two will be subjected to the grinding force applied by the rotating slider 6, thereby causing the particle size of the lithium ore to be further reduced, thereby further accelerating the grinding efficiency of the lithium ore. Afterwards, after the grinding roller 2 leaves the slider 6, the upward reset slider 6 continues to rotate. Through this action, the particles in contact with the slider 6 are further prompted to leave the current position (the powder and particles in contact with the circumferential side of the slider 6 will be moved by the rotating slider 6. At the same time, due to the rotation of the slider 6, the contact between the upward slider 6 and the gradually moving away grinding roller 2 is more uniform), and stacked with the particles in the remaining positions, so that when the subsequent grinding roller 2 contacts this part of the particles again, the extrusion and grinding effect of this part of the particles is improved.
