Description

Technical Field

[0001] This invention belongs to the field of sorting equipment technology, specifically a mineral geological exploration sample sorting device. Background Technology

[0002] To better understand the geological conditions, it is generally necessary to extract geological samples from the corresponding geological locations for mineral analysis. Before testing the geological samples, they need to be sorted to facilitate subsequent individual testing and analysis.

[0003] During use, the ore sample is fed into the device through the feed inlet. After being crushed by the crushing mechanism, the ore sample is crushed to a certain particle size. The crushed ore sample falls onto the screening mechanism, where it is screened to separate small and large particles. Small particles fall through the sieve holes, while large particles accumulate on the screening mechanism. Large particles can be fed back into the device through the return port for further crushing and screening to improve the sample sorting rate.

[0004] However, the above screening process is only one screening. If the large particles in the sample need to be crushed again after screening, they need to be screened again through the return port. The screening process is too complicated. In addition, mineral dust and soil will be mixed in during the crushing process, which will affect the sample test results. Summary of the Invention

Both the filter cover plate and the crushing cover plate are inclined towards the gap between adjacent fixed frames. The transverse inner diameter of the several connecting cover plates gradually decreases from top to bottom.

[0008] The crushed block has a ring-shaped structure, and the outer side of the upper surface of the crushed block is inclined downward. The distance between the surface of the crushed block and the crushing cover plate gradually decreases from top to bottom.

[0028] The technical solution of this application will be further described in detail below with reference to specific embodiments.

[0029] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0030] Please see Figures 1 to 9 In one embodiment, a mineral geological exploration sample sorting device includes a cylinder 1, a rotating column 10, a fixed frame 9, and a power component 3. The rotating column 10 is provided with a water injection chamber 101 and is rotatably installed inside the cylinder 1. The power component 3 is connected to the rotating column 10 and is used to drive the rotating column 10 to rotate. Several fixed frames 9 are fixedly installed on the rotating column 10. The lateral inner diameter of the several fixed frames 9 gradually decreases from top to bottom. Several overflow holes 102 are opened on the rotating column 10 between adjacent fixed frames 9.

[0031] A crushing block 8 is installed on the fixed frame 9, and a plurality of connecting cover plates 15 are installed on the cylinder 1. The connecting cover plates 15 are inverted funnel-shaped. A filter plate 18 is installed between the cylinder 1 and the connecting cover plates 15. A filter cover plate 16 and a crushing cover plate 17 are fixedly installed between adjacent connecting cover plates 15. The filter cover plate 16 is located above the crushing cover plate 17. The filter cover plate 16 and the crushing cover plate 17 are fixedly connected. The filter cover plate 16 and the crushing cover plate 17 are both inclined toward the gap between adjacent fixed frames 9. The lateral inner diameter of the plurality of connecting cover plates 15 gradually decreases from top to bottom.

[0032] The crushing block 8 has a ring-shaped structure, and the outer side of the upper surface of the crushing block 8 is inclined downward. The distance between the surface of a single crushing block 8 and the crushing cover plate 17 gradually decreases from top to bottom, and the distance between the surfaces of several crushing blocks 8 and the crushing cover plate 17 gradually decreases from top to bottom.

[0033] In this embodiment, the filter cover plate 16 has a plurality of filter holes 160. The top of the cylinder 1 is fitted with a cover plate 11, and the cover plate 11 has a feed inlet 12. The cylinder 1, the connecting cover plate 15, the filter cover plate 16, and the crushing cover plate 17 are integrally formed. The filter cover plate 16 and the crushing cover plate 17 are arranged in three sets. The uppermost set of filter cover plates 16 and crushing cover plates 17 has a feed chamber 20 above it and a first crushing chamber 21 below it. The lowermost set of filter cover plates 16 and crushing cover plates 17 has a second crushing chamber 22 above it and a third crushing chamber 23 below it. One end of the filter plate 18 is fixedly installed on the inner wall of the cylinder 1, and the other end is fixedly installed on the lowermost connecting cover plate 15. The upper part of the filter plate 18 is a collection chamber, and the lower part is a filtration chamber. The cylinder 1 has a first discharge port 13 above the filter plate 18 and a second discharge port 14 below the filter plate 18.

[0034] During sorting, the sample is first poured into the cylinder 1. When the sample enters the filter cover 16, water is sprayed onto the sample through the overflow hole 102 located above the rotating column 10. At the same time, small-diameter samples, soil, and mineral dust enter the collection chamber through the filter cover 16. The remaining sample material enters between the crushing cover 17 and the crushing blocks 8. The distance between the sample material and the crushing cover 17 gradually decreases along the movement path of the crushing blocks 8, thereby further crushing the large-diameter material through the crushing blocks 8. The small-diameter material formed after crushing... The material will enter the collection chamber through the next filter cover 16 and undergo another crushing cycle. The distance between the crushing cover 17 and the crushed block 8 gradually decreases in each cycle, which corresponds to the crushing process. When the material enters the third crushing chamber 23, it will enter the material pipe 4 through the feed port 40 for discharge. At the same time, the material in the collection chamber also contains water. During the entire crushing process, the addition of water can wash away the mineral dust and mud. The filter plate 18 can remove water, mineral dust and mud.

[0035] By flushing with water during the sorting process, the mineral dust and mud on the sample surface can be washed away to avoid affecting the test results. With several filter covers 16 and crushing covers 17, several crushing and filtering operations can be performed. The incompletely crushed part directly enters the next crushing space without being discharged and re-feeded.

[0036] Please see Figure 3 , Figure 7 In one embodiment, a material pipe 4 is movably installed at the bottom end of the rotating column 10, and an inlet 40 is provided on the material pipe 4.

[0037] In this embodiment, the feed inlet 40 is located inside the third crushing chamber 23. By providing a feed pipe 4, the crushed sample inside the third crushing chamber 23 can be introduced to the outside of the feed pipe 4 through the feed inlet 40.

[0038] Please see Figure 3 , Figure 4 and Figure 5 In one embodiment, it also includes a water inlet pipe 2, which extends to the bottom of the water injection chamber 101.

[0039] In this embodiment, the water inlet pipe 2 is connected to a water pump. By extending one end of the water inlet pipe 2 to the bottom of the water injection chamber 101, water overflows through the gap between the water inlet pipe 2 and the inner wall of the water injection chamber 101, which can further increase the water pressure. When water overflows from the overflow hole 102, the water pressure washes away the mineral dust and soil on the sample surface, thereby removing the mineral dust and soil.

[0040] Please see Figure 8 In one embodiment, a plurality of breaking teeth 82 are provided on the upper surface of the breaking block 8.

[0041] In this embodiment, by providing crushing teeth 82, the crushing teeth 82 can squeeze and crush the sample below the crushing cover plate 17.

[0042] Please see Figure 3 , Figure 4 and Figure 5 In one embodiment, a guide block 5 is fixedly installed on the rotating column 10, and the guide block 5 is located at the end of the rotating column 10 away from the material pipe 4.

[0043] In this embodiment, the upper surface of the guide block 5 is inclined, so that the sample slides down the guide block 5 under the action of gravity and enters the first crushing chamber 21 for crushing. Secondly, when the rotating column 10 drives the guide block 5 to rotate, the sample can be evenly dispersed in all directions to avoid local concentration of the sample.

[0044] Please see Figure 7 , Figure 8 In one embodiment, the inner wall of the crushing block 8 is provided with an internal thread 80, the fixing frame 9 is provided with an external thread 93 that mates with the internal thread 80, and a spring 81 is provided between the fixing frame 9 and the crushing block 8.

[0045] In this embodiment, the fixed frame 9 is provided with a sink 92 and an annular groove 91, the spring 81 is located in the annular groove 91, and the broken block 8 is located in the sink 92.

[0046] When the rotating column 10 moves in one direction, the bottom of the crushing block 8 is in contact with the upper surface of the settling tank 92. At this time, the rotation direction is the same as the direction of the downward movement of the crushing block 8's thread. When the sample stops between the crushing cover plate 17 and the crushing block 8, the rotating column 10 is driven to rotate in the opposite direction. Under the action of the spring 81, the crushing block 8 tends to move upward. At the same time, due to the cooperation between the external thread 93 and the internal thread 80, the crushing block 8 eventually moves upward. While the crushing block 8 is moving upward, its surface presses against the stopped sample until the sample is crushed. At this time, the rotating column 10 returns to its initial rotation direction, and the sample will fall onto the next filter cover plate 16 along the slope 19 of the crushing block 8.

[0047] Please see Figure 3 , Figure 4 and Figure 5 In one embodiment, both the guide block 5 and the bottom of the fixed frame 9 are fixedly installed with telescopic components 7, and the output end of the telescopic component 7 is equipped with a plug 6. The size of the plug 6 is adapted to the gap between the crushing cover plate 17 and the filter cover plate 16.

[0048] In this embodiment, the guide block 5 and the fixed frame 9 are respectively provided with a first receiving groove 50 and a second receiving groove 90 at their bottoms, and the telescopic member 7 is located in the first receiving groove 50 or the second receiving groove 90.

[0049] By providing the plug 6, the feeding speed of the feed chamber 20, the first crushing chamber 21, the second crushing chamber 22 and the third crushing chamber 23 can be controlled. For example, if there are many samples in the feed chamber 20, the plug 6 can be moved by the telescopic component 7, so that the plug 6 can block the gap between the rotating column 10 and the crushing cover plate 17 and the filter cover plate 16 or control the size of the gap, thereby stopping the feeding or slowing down the speed at which the sample enters the first crushing chamber 21.

[0050] Please see Figure 2 , Figure 3 In one embodiment, the outer side of the filter plate 18 is inclined downward.

[0051] In this embodiment, the bottom of the cylinder 1 is a slope 19, and the outer side is inclined downwards. The bottom outer side of the third crushing chamber 23 is inclined upwards. By setting the outer side of the filter plate 18 and the bottom outer side of the third crushing chamber 23 to be inclined downwards, it is convenient to discharge materials.

[0052] Please see Figure 3In one embodiment, the power assembly 3 includes a motor 31, a drive gear 32, and a driven gear 34. The motor 31 is mounted on the cylinder 1, and the output shaft 33 of the motor 31 is fixedly connected to the drive gear 32. The driven gear 34 is fixedly mounted on the rotating column 10, and the driven gear 34 is meshed with the drive gear 32.

[0053] In this embodiment, the output shaft 33 passes through the bottom of the cylinder 1. The output shaft 33 is driven to rotate by the starter motor 31. The rotation of the output shaft 33 drives the drive gear 32 to rotate, and the rotation of the drive gear 32 drives the driven gear 34 and the rotating column 10 to rotate.

[0054] The working process of this invention is as follows: First, the sample is poured in through the feed inlet 12. The sample collides with the guide block 5 and slides down the surface of the guide block 5. The rotating column 10 drives the guide block 5 to rotate, so that the sample is evenly dispersed around. When the sample enters the filter cover plate 16, the overflow hole 102 located above the rotating column 10 sprays water onto the sample. At the same time, small-diameter samples, soil, and mineral dust will enter the collection chamber through the filter cover plate 16. The remaining sample material will enter between the crushing cover plate 17 and the crushing block 8. The distance between the sample material and the crushing cover plate 17 on the movement path of the crushing block 8 will gradually decrease, thereby passing through the crushing block 8. Large-diameter materials are further crushed and compressed. The small-diameter materials formed after crushing will enter the collection chamber through the next filter cover plate 16 and undergo the next crushing cycle. In each cycle, the distance between the crushing cover plate 17 and the crushed blocks 8 gradually decreases, which corresponds to the crushing process. When the material enters the third crushing chamber 23, the material will enter the material pipe 4 through the feed port 40 for discharge. At the same time, the material in the collection chamber also contains water. During the entire crushing process, the addition of water can wash away the mineral dust and mud. The filter plate 18 can remove water, mineral dust and mud.

[0055] When the sample stops between the crushing cover plate 17 and the crushed block 8, the drive rotating column 10 rotates in the opposite direction. Under the action of the spring 81, the crushed block 8 tends to move upward. At the same time, due to the cooperation between the external thread 93 and the internal thread 80, the crushed block 8 eventually moves upward. While the crushed block 8 is moving upward, its surface presses against the stopped sample until the sample is crushed. At this time, the rotating column 10 returns to its initial direction of rotation, and the sample will fall onto the next filter cover plate 16 along the slope 19 of the crushed block 8.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
