Description

Technical Field

[0001] The utility model belongs to the technical field of ore crushing, and specifically relates to a circulating separation type ore crushing device. Background Art

[0002] The crushing of ore is a process of using external force to break large ore or ore to be processed, overcoming the internal forces between its various parts, and gradually reducing the particle size of the ore. In the ore dressing process, the crushing of ore is an essential material preparation stage before the separation operation.

[0003] The crushing of ore is a necessary stage for the utilization of ore after it is mined. Existing traditional crushers only crush the ore once or multiple times after mining, and it is impossible to reduce the particle size or there are always sporadic individuals with larger volumes. Moreover, before the ore is mined, a large amount of sundries are mixed in it, increasing the working difficulty and reducing the ore dressing efficiency during ore dressing.

[0004] For example, the utility model with the patent number CN202222726117.0 discloses a circulating type ore crusher. A conveying device is fixedly installed on the right side of the device bin of this utility model device, and a plurality of collection bins are fixedly connected to the conveying mechanism. The ore is broken by the crushing component in the device bin, and the ore that does not meet the requirements enters the collection bin through the discharge chute on the right side of the device bin and is sent to the top of the device bin by electric drive for secondary crushing. However, before the ore is crushed by this utility model, the ore is not pretreated, resulting in small particles being mixed into the ore, reducing the cleanliness of the ore and the ore dressing efficiency.

[0029] Figures 1 to 3The figure shows a cyclic separation type ore crushing device of the utility model, including:

[0030] A rectangular bin body 1, with a feed inlet 3 at the top, a discharge outlet 23 at the bottom, and a maintenance opening 27 on the left side. A plurality of support columns 2 are connected to the bottom of the rectangular bin body 1, and a rectangular outer shell 14 is detachably connected to the left side. A screening plate 22 is arranged inside the rectangular bin body 1;

[0031] A crushing assembly, which includes a main rotating shaft 18 and a central shaft 16. The central shaft 16 penetrates through the main rotating shaft 18 and is connected to the main rotating shaft 18. A plurality of crushing heads 24 are fixed on the main rotating shaft 18. Both ends of the central shaft 16 are connected to the rectangular bin body 1 through bearings. One end of the central shaft 16 extends out of the rectangular bin body 1 and is connected to a transmission belt 17, and the other end of the transmission belt 17 is connected to a driving motor 19;

[0032] A wind tube 6, which is connected to the top of the rectangular bin body 1 through a plurality of support columns 13, and the air outlet of the wind tube 6 faces the feed inlet 3. Working principle: When using the utility model, the wind tube 6 and the driving motor 19 are turned on, and the ore is transported to the feed inlet 3. The wind tube 6 removes the impurities in the ore by wind force. The ore enters the rectangular bin body 1. The driving motor 19 drives the transmission belt 17 to rotate, and the transmission belt 17 drives the central shaft 16 to rotate, so that the crushing heads 24 make a circular motion to crush the ore. The qualified ore after crushing is screened out by the screening plate 22 and discharged from the discharge outlet 23, and the unqualified ore continues to be crushed until the particle size of the ore can pass through the screening plate 22.

[0033] In the above technical solution, a plurality of convex structures 15 are arranged on the rectangular outer shell 1, and a plurality of grooves 26 that fit with the convex structures 15 are arranged on the left side of the rectangular bin body 1; A support platform 12 is arranged outside the rectangular bin body 1, and a support column 11 is connected to the bottom of the support platform 12. In this way, the tight connection between the convex structure 15 and the groove 26 makes the connection between the rectangular outer shell 14 and the rectangular bin body 1 more stable, and the setting of the support platform 12 can better fix other components.

[0034] In the above technical solution, the bottom of the driving motor 19 is connected to a motor base 10, the motor base 10 is fixedly connected to the support platform 12, and a protective shell 7 is arranged outside the transmission belt 17. In this way, the driving motor drives the transmission belt for transmission, and the protective shell can isolate dust and protect the transmission device.

[0035] In the above technical solution, a baffle a20 and a baffle b21 are arranged inside the rectangular bin body 1. One end of the baffle a20 is connected to the rectangular bin body 1, and the other end is connected to the baffle b21. The other end of the baffle b21 is connected to the rectangular bin body 1. The slope of the baffle a20 is greater than that of the baffle b21. In this way, when the ore is broken, it can more effectively contact the crushing head, and at the same time guide the movement path of the ore, so that the broken ore can smoothly fall on the screening plate 22.

[0036] In the above technical solution, one end of the screening plate 22 is connected to the rectangular bin body 1, and the other end is connected to the connection formed by the connection of the baffle a20 and the baffle b21. The screening plate 22 is a horizontal plate surface with a certain degree of curvature, and several material passing openings 25 are opened on the plate surface. In this way, after the ore is broken, it falls on the screening plate under the action of gravity. The qualified ore passes through the material passing openings, and the unqualified ore continues to be broken, so as to more effectively screen the ore.

[0037] In the above technical solution, a conveying device a4 is arranged above the feed inlet 3, and a conveying device b5 is arranged below the discharge outlet 23. The width of the conveying device a4 is smaller than the width of the feed inlet 3, and the width of the conveying device b5 is greater than the width of the discharge outlet 23. In this way, the feeding and discharging of the ore are both transported by the conveying device, reducing the labor cost and labor intensity.

[0038] In the above technical solution, the rectangular outer shell 14 is connected to the hydraulic connecting rod 9, and the other end of the hydraulic connecting rod 9 is connected to the hydraulic device 8. The hydraulic device 8 is fixedly connected to the support platform 12. In this way, when the hydraulic device is started, the hydraulic connecting rod can quickly disassemble the rectangular bin body, facilitating the maintenance of the crushing assembly.
