Description

Technical Field

[0001] The invention relates to the technical field of ore crushing, and in particular to a mining ore crushing device. Background Art

[0002] Ore crushing refers to the physical process of changing ore from large pieces or whole pieces into small pieces by applying external force to overcome the cohesive force between ore molecules. Ore crushing is an important part of the mineral processing process. It involves the use of various crushing equipment (such as jaw crusher, hammer crusher, cone crusher, column crusher, impact crusher, etc.) to crush the ore to achieve specific particle size and shape requirements. The main purpose of this process is to provide materials with suitable particle size and shape for subsequent mineral processing operations. Ore crushing can be divided into two stages: crushing in the coarse-grained stage and grinding in the fine-grained stage. Crushing in the coarse-grained stage mainly breaks large pieces of ore into smaller-sized materials, while grinding in the fine-grained stage further refines the materials to meet the requirements of the mineral processing process. The efficiency and output of ore crushing are important criteria for measuring the quality of an ore crushing production line.

[0003] At present, when the column crusher is put into use at the mining site, workers will add ore from the top of the column crusher, and the motor drives the vertical shaft to drive the rotor to rotate, thereby bringing the ore into the tooth plate of the crushing chamber for impact crushing. Since the tooth plate is a fixed-position impact structure, the impact crushing frequency of the ore is not good. When some wet ore enters the column crusher, the ore material is easy to adhere to the tooth plate, and the adhered material will affect the normal operation of the crusher, reduce its production efficiency, and may cause excessive wear of equipment components. In addition, the column crusher lacks an effective drying treatment structure for the ore at the feed port, which makes it inconvenient for the column crusher to handle wet ore. For this reason, we propose a mining ore crushing device. Summary of the invention

[0004] The main purpose of the present invention is to provide a mining ore crushing device. The present invention optimizes and improves the existing column crusher used for mining ore crushing. A barrel driving mechanism is arranged between the original vertical barrel and the crushing rotor of the column crusher. The barrel driving mechanism enables a structure that can rotate with a tooth plate between the original vertical barrel and the crushing rotor of the column crusher. When the crushing rotor of the column crusher rotates clockwise to hit the ore, the tooth plate is driven by the inner rotating barrel of the barrel driving mechanism to rotate counterclockwise, so that the tooth plate can hit the ore impacting itself back to the crushing rotor for counter-crushing, thereby improving the efficiency of ore impact crushing and crushing. The rotor and the tooth plate have a high efficiency in crushing the ore by efficient collision with each other, so that the ore is not likely to stick between the crushing rotor and the tooth plate. The drying mechanism can provide a structure for long-distance heating of the ore at the feed seat, so that the ore with high humidity carries less moisture after heating and drying. The dried ore has less moisture when entering between the crushing rotor and the tooth plate for crushing, and is not likely to stick to the ore. In addition, the damage to the rotating tooth plate when it is hit will be reduced, which effectively improves the service life of the tooth plate during ore crushing, and also indirectly improves the service life of the crushing rotor, which can effectively solve the problems in the background technology.

[0010] Furthermore, a supporting ball is protruded from the inner seat wall surface of the inner supporting bucket seat below the vertical cylinder, a bottom rotating bucket seat is supported on the surface of the supporting ball, and a vertical shaft of the crushing rotor is inserted downward into the shaft seat between the bottom rotating bucket seat and the seat opening of the inner supporting bucket seat, and the seat body size of the inner supporting bucket seat is smaller than the cavity size of the leakage port;

[0011] By adopting the above preferred technical solution, when the inner rotating drum in the vertical drum rotates, the bottom rotating bucket seat of the inner rotating drum can be pressed on the supporting ball of the inner supporting bucket seat for spherical support during rotation. If necessary, an annular groove can be provided on the lower surface of the bottom rotating bucket seat to clamp the supporting ball, thereby ensuring that the bottom rotating bucket seat can rotate smoothly at the inner supporting bucket seat.

[0014] Furthermore, the plate body surface of the tooth plate is recessed with a mounting groove, and bolts are screwed between the mounting groove of the tooth plate and the inner drum, and the arc-shaped plate body of the tooth plate is pressed on the inner drum wall of the inner drum and fixed in an annular distribution;

At the same time, the tooth plate forms a structure in the inner drum that is impacted by ore.

[0016] Furthermore, the groove cavity of the semi-concave groove and the seat cavity of the outer press seat form a truncated cone-shaped cavity for supporting the truncated cone pressing block, and a gear shaft extends from the vertical cavity below the truncated cone-shaped cavity;

[0018] Furthermore, a straight key is clamped at the keyway on the surface of the output shaft of the motor, and the output shaft of the motor is inserted upward into the shaft hole of the gear shaft in cooperation with the straight key;

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention optimizes and improves the existing column crusher for mining ore crushing. A barrel driving mechanism is arranged between the original vertical barrel and the crushing rotor of the column crusher. The barrel driving mechanism enables a structure that can rotate with a tooth plate between the original vertical barrel and the crushing rotor of the column crusher. When the crushing rotor of the column crusher rotates clockwise to hit the ore, the tooth plate is driven by the inner rotating barrel of the barrel driving mechanism to rotate counterclockwise, so that the tooth plate can hit the ore impacting itself back to the crushing rotor for counter-impact crushing, thereby improving the efficiency of ore impact crushing. The efficiency of the crushing rotor and the tooth plate in efficiently impacting and crushing the ore is high, so that the ore is not easy to stick between the crushing rotor and the tooth plate.

[0026] The drying mechanism can provide a long-distance heating structure for the ore at the feed seat, so that the ore with high humidity carries less moisture after heating and drying. The dried ore has less moisture when it enters the crushing rotor and the tooth plate, and is less likely to cause sticking problems.

[0027] In addition, the damage to the rotating tooth plate when it is hit will be reduced, which effectively increases the service life of the tooth plate during ore crushing; at the same time, it also indirectly increases the service life of the crushing rotor. BRIEF DESCRIPTION OF THE DRAWINGS

The outer tube wall of the feed pipe 27 is coated with a nano-thermal conductive layer 28, and a heating coil 29 is wound around the nano-thermal conductive layer 28.

[0041] like Figure 3 and Figure 4As shown, the diameter of the cylinder cavity of the vertical cylinder 4 is larger than the outer cylinder diameter of the inner cylinder 12, and the cylinder cavity size of the inner cylinder 12 is larger than the size of the crushing rotor 6, and a rotational clearance is reserved between the passive gear ring 14 outside the inner cylinder 12 and the inner cylinder wall of the vertical cylinder 4;

[0042] By adopting the above preferred technical solution, when the gear shaft 17 of the active gear disc 15 is driven by the motor 22 to rotate with the passive gear ring 14 and the inner rotating cylinder 12, the cylinder cavity of the vertical cylinder 4 can accommodate the rotation of the inner rotating cylinder 12, and the passive gear ring 14 of the inner rotating cylinder 12 can also rotate smoothly in the vertical cylinder 4, so that the passive gear ring 14 will not damage the inner cylinder wall of the vertical cylinder 4 when rotating.

[0043] like Figure 7 and Fig. 9 As shown, a supporting ball 10 is protruded from the inner seat wall surface of the inner supporting bucket seat 9 below the vertical cylinder 4, a bottom rotating bucket seat 11 is supported on the surface of the supporting ball 10, and a vertical shaft of the crushing rotor 6 is inserted downward into the shaft seat 3 between the bottom rotating bucket seat 11 and the seat opening of the inner supporting bucket seat 9, and the seat body size of the inner supporting bucket seat 9 is smaller than the cavity size of the leakage port 2;

[0044] By adopting the above-mentioned preferred technical scheme, when the inner rotating drum 12 in the vertical drum 4 rotates, the bottom rotating bucket seat 11 of the inner rotating drum 12 can be pressed on the supporting ball 10 of the inner supporting bucket seat 9 for spherical support during rotation. If necessary, an annular groove can be provided on the lower surface of the bottom rotating bucket seat 11 to clamp the supporting ball 10, thereby ensuring that the bottom rotating bucket seat 11 can rotate smoothly at the inner supporting bucket seat 9.

[0045] like Figure 3 and Figure 4 As shown, three groups of grooves of top-mounted half grooves 23 are opened at three points on the inner cylinder wall of the vertical cylinder 4, and three groups of columns of limited movable columns 24 are clamped in the three groups of groove cavities of the top-mounted half grooves 23, and the circular cylinders of the limited movable columns 24 are pressed between the vertical cylinder 4 and the inner rotating cylinder 12;

[0046] By adopting the above-mentioned preferred technical solution, the vertical cylinder 4 has three groups of top-mounted half grooves 23 to clamp three groups of limit posts 24. The limit posts 24 can provide three-point auxiliary rotation points when the inner rotating cylinder 12 rotates, so that the inner rotating cylinder 12 can rotate smoothly in the vertical cylinder 4.

[0047] like Figure 4 and Fig. 9 As shown, the plate surface of the tooth plate 13 is recessed with a mounting groove, and bolts are screwed between the mounting groove of the tooth plate 13 and the inner drum 12, and the arc-shaped plate body of the tooth plate 13 is pressed on the inner drum wall of the inner drum 12 and fixed in an annular distribution;

[0048] By adopting the above preferred technical solution, the bolts can be screwed into the inner wall of the inner drum 12 from the mounting groove of the tooth plate 13 to install the tooth plate 13, and the heads of the bolts can enter and hide in the mounting groove of the tooth plate 13. At the same time, the tooth plate 13 forms a structure in the inner drum 12 that is impacted by ore.

[0049] like Figure 4 and Figure 5 As shown, the groove cavity of the semi-recessed groove 19 and the seat cavity of the outer press-fit seat 20 form a truncated cone-shaped cavity for supporting the truncated cone pressing block 18, and a gear shaft 17 extends from the vertical cavity below the truncated cone-shaped cavity;

[0050] By adopting the above-mentioned preferred technical solution, after the external crimping seat 20 is locked outside the base 1 to cover the semi-recessed groove 19, the conical pressure block 18 of the gear shaft 17 can be inserted into the conical cavity between the groove cavity of the semi-recessed groove 19 and the external crimping seat 20, and the vertical axis of the gear shaft 17 can extend downward from the groove cavity of the semi-recessed groove 19 and the vertical cavity between the external crimping seat 20, so as to facilitate the axial connection between the gear shaft 17 and the motor 22.

[0051] like Figure 5 and Figure 6 As shown, a straight key is clamped at the keyway on the surface of the output shaft of the motor 22, and the output shaft of the motor 22 is inserted upward into the shaft hole of the gear shaft 17 in cooperation with the straight key;

[0052] By adopting the above preferred technical solution, after the output shaft of the motor 22 is clamped with a straight key, the conveying shaft with a straight key can be inserted into the corresponding shape shaft hole of the gear shaft 17 for a straight key plug-in shaft connection, ensuring that the gear shaft 17 can be driven by the motor 22.

[0055] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cavity size of the toothed opening 15 is larger than the tooth body size at the meshing point of the active toothed disc 16 and the passive gear ring 14;

[0056] By adopting the above preferred technical solution, the toothed opening 15 can better accommodate the meshing and rotation of the active toothed disc 16 and the passive gear ring 14, making it convenient for the active toothed disc 16 to drive the passive gear ring 14 to rotate with the inner drum 12.

[0057] It should be noted that the present invention is a mining ore crushing device. The present invention optimizes and improves the existing column crusher for mining ore crushing. A cylinder driving mechanism is arranged between the original vertical cylinder 4 and the crushing rotor 6 of the column crusher. When the vertical cylinder 4 is assembled with the original base 1 of the column crusher, the bottom locking ring 8 of the vertical cylinder 4 is pressed on the surface of the base 1 outside the leakage port 2 and is locked with bolts. At this time, the inner support bucket seat 9 below the vertical cylinder 4 is inserted into the leakage port 2 and covered outside the shaft seat 3, and then the inner support bucket seat 9 below the vertical cylinder 4 is inserted into the leakage port 2 and covered outside the shaft seat 3. The rotating drum 12 can be placed into the inner cavity of the vertical drum 4 from the top of the vertical drum 4, so that the bottom rotating bucket seat 11 of the inner rotating drum 12 is covered outside the shaft seat 3, and the bottom rotating bucket seat 11 is pressed on the surface of the supporting ball 10 of the inner supporting bucket seat 9 to obtain spherical support, and then the stop column 24 is inserted into the top half groove 23 of the vertical drum 4, so that the column body of the stop column 24 is against the outside of the inner rotating drum 12 in the top half groove 23, and then the gear shaft 17 under the active gear disc 16 is inserted into the semi-recessed groove 19 on the outer side of the base 1. The active gear disc 16 is meshed with the passive gear ring 14 from the exposed toothed opening 15 of the vertical cylinder 4 and the bottom lock ring 8, and then the external press-fit seat 20 is locked on the outer surface of the base 1 to cover and support the truncated cone pressing block 18 of the gear seat 17. When the vertical shaft body of the gear shaft 17 extends downward from the groove cavity of the semi-recessed groove 19 and the vertical cavity between the external press-fit seat 20, the conveying shaft of the motor 22 is inserted upward into the corresponding shape shaft hole of the gear shaft 17 for straight key plug-in shaft connection, and then bolts are used to fix The base of the motor 22 is locked on the surface of the horizontal support plate 21. At this time, the crushing rotor 6 installed with the vertical shaft under the cylinder cover 5 can be put into the inner drum 12, so that the vertical shaft is inserted into the shaft seat 3, and the crushing rotor 6 enters the inner drum 12. Then the cylinder cover 5 and the upper ring body of the vertical cylinder 4 are locked by bolts. At this time, the cylinder drive mechanism is assembled at the vertical cylinder 4 and the base 1. The worker connects the pulley above the original drive motor of the column crusher with a belt body at the pulley of the vertical shaft extending above the cylinder cover 5;

[0058] Then the worker can assemble the drying mechanism at the upper seat opening of the feed seat 7. The upper seat 26 of the drying mechanism is inserted into the feed seat 7 with the bottom insert seat 25 for clamping. At the same time, the feed pipe 27 outside the upper seat 26 is provided with a nano-thermal conductive layer 28 to cooperate with the winding heating coil 29. The heating coil 29 needs to be electrically connected to an external power supply. If necessary, a support frame can be installed between the tube body of the feed pipe 27 without the nano-thermal conductive layer 28 and the base 1 for support.

[0059] When the mined ore needs to be crushed, the ore can slide from the inclined slide 30 of the feed pipe 27 into the upper receiving seat 26. When the ore passes through the feed pipe 27, the heating coil 29 can heat the feed pipe 27 and the inclined slide 30, so that the ore is heated and dried when sliding through here, reducing the moisture carried by the ore. The dried ore falls downward into the inner drum 12 along the bottom insert seat 25 and the feed seat 7 at the upper receiving seat 26;

[0060] At this time, the crushing rotor 6 rotates at a high speed in the inner drum 12, and the motor 22 drives the active toothed disc 16 through the gear shaft 17 to maintain a rotation direction opposite to that of the crushing rotor 6, so that the passive gear ring 14 meshing with the active toothed disc 16 rotates with the inner drum 12. When the inner drum 12 rotates, there is a limit column 24 between the upper part of the inner drum 12 and the vertical drum 4 to provide upper three-point support, and the bottom of the inner drum 12 is pressed by the bottom rotating bucket seat 11 on the surface of the inner supporting bucket seat 9 of the vertical drum 4. The ball 10 rotates smoothly, so that the inner drum 12 and the tooth plate 13 maintain a rotation direction opposite to that of the crushing rotor 6;

[0061] When the ore is hit by the crushing hammer of the crushing rotor 6 and rushes toward the tooth plate 13, the impact damage suffered by the counter-rotating tooth plate 13 will be reduced, and the counter-rotating tooth plate 13 can reversely hit the ore back to the crushing rotor 6, so that the ores collide and crush with each other, increasing the contact frequency when the ore collides and crushes, and the ore crushing effect of high-frequency collision is higher, making it less likely for the tooth plate 13 and the crushing rotor 6 to have a sticking problem, and the ore slag crushed by the multi-layer crushing hammer structure of the crushing rotor 6 can fall downward along the inner support bucket seat 9 to the leak 2 and fall out below the base 1;

[0062] The crushing rotor 6 of the column crusher can be set to rotate clockwise to hit the ore, and the tooth plate 13 is driven by the inner drum 12 of the driving drum mechanism and can be set to rotate counterclockwise, so that the tooth plate 13 can hit the ore that impacts itself back to the crushing hammer body of the crushing rotor 6 for impact crushing, which greatly improves the efficiency of ore impact crushing. The efficiency of the crushing rotor 6 and the tooth plate 13 to efficiently impact and crush the ore is high, so that the ore is not easy to stick between the crushing rotor 6 and the tooth plate 13;

[0063] When the drying mechanism is arranged at the feeding seat 7, the drying mechanism can provide a structure for heating the ore over a long distance, so that the ore with high humidity carries less water after being heated and dried, and the dried ore has less water when entering between the crushing rotor 6 and the tooth plate 13 for crushing, and the problem of sticking is not easy to occur;

[0064] When the tooth plate 13 rotates, the rotating tooth plate 13 will disperse the impact force it receives when it is hit, thereby reducing the impact damage received by the tooth plate 13, effectively improving the service life of the tooth plate 13 during ore crushing. When the ore is quickly crushed by the opposite impact between the crushing rotor 6 and the tooth plate 13, the service life of the crushing rotor 6 is also indirectly improved.
