Description

Technical Field

[0001] This utility model relates to the field of sorting device technology, specifically a circulating gold concentrate sorting device. Background Technology

[0002] Gold concentrate, also known as gold powder, is mineral powder produced from natural gold ore through crushing, grinding, and beneficiation. Since it is formed from gold ore, its main components are gold and silicon dioxide. During the preparation of gold concentrate, sorting equipment is needed to separate impurities. However, existing sorting devices, while separating the gold concentrate, cannot separate clumps within the powder, leading to waste. Furthermore, the separated impurities are difficult to clean. Therefore, improvements to the existing technology are necessary. Utility Model Content

[0003] The purpose of this invention is to provide a circulating gold concentrate sorting device, which solves the problems of gold concentrate caking and filtration, which can lead to waste and make it difficult to clean the impurities generated after sorting.

[0006] Preferably, the output shaft of the motor is fixedly connected to the rotating shaft, and the large gear meshes with the small gear, so that the small gear can drive the large gear to rotate slowly.

[0007] Preferably, the reamer shaft contacts the inner wall of the circulation pipe, and the reamer shaft is connected to the fixing bar via a bearing. The reamer shaft can lift raw materials that cannot pass through the secondary filter cover.

[0008] Preferably, one end of the tension spring is fixedly connected to the sliding ring, the tension spring is fixedly connected to the guide ring, the secondary filter cover is slidably connected to the circulation pipe, and the circulation pipe is fixedly connected to the primary filter cover. The tension spring can drive the sliding ring to automatically reset.

[0009] Preferably, the limiting mechanism includes fixed pins, and two symmetrically distributed fixed pins are fixedly connected to the upper outer side of the sorting box. A connecting frame is slidably connected to the outer side of each of the two fixed pins. A limiting frame is fixedly connected between the two connecting frames. A spring is provided on the outer side of each fixed pin. One end of the spring is fixedly connected to the connecting frame, and the other end of the spring is fixedly connected to the fixed pin.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model adds a secondary filter cover, a circulation pipe and a reamer shaft inside the sorting box. During the sorting process of raw materials, the raw materials that cannot pass through the secondary filter can be lifted into the interior of the primary filter cover for further crushing through the cooperation between the reamer shaft and the circulation pipe. This reduces the volume of agglomerates through circulating crushing and can effectively improve the utilization rate of gold concentrate.

[0012] 2. This utility model adds a limiting frame, fixing nails and connecting frame to the sorting box. During use, the spring force can drive the limiting frame to engage with the outside of the box cover to limit the box cover. When it is necessary to open the box cover, the limiting frame can be removed from the box cover to release the limitation on the box cover, thus making it easier to open the box cover and clean the impurities inside.

[0021] Please see Figure 1 , Figure 2 , Figure 3A bracket 3 is fixedly connected to the lower end of the sorting box 1, and a discharge pipe 4 is fixedly connected to the lower end of the sorting box 1. The discharge pipe 4 can transport the sorted raw materials. The output shaft of the motor 14 is fixedly connected to the rotating shaft 8. The large gear 12 meshes with the small gear 13. The small gear 13 can drive the large gear 12 to rotate slowly. The reamer shaft 11 contacts the inner wall of the circulation pipe 10. The reamer shaft 11 is connected to the fixed bar 6 through a bearing. The reamer shaft 11 can lift the raw materials that cannot pass through the secondary filter cover 17. One end of the tension spring 18 is fixedly connected to the sliding ring 16. The tension spring 18 is fixedly connected to the guide ring 15. The secondary filter cover 17 is slidably connected to the circulation pipe 10. The circulation pipe 10 is fixedly connected to the primary filter cover 7.

[0022] Please see Figure 2 , Figure 4 , Figure 5 The limiting mechanism 5 includes fixed pins 51. Two symmetrically distributed fixed pins 51 are fixedly connected to the upper outer side of the sorting box 1. A connecting frame 52 is slidably connected to the outer side of each of the two fixed pins 51. A limiting frame 53 is fixedly connected between the two connecting frames 52.
