Description

Technical Field

[0001] The utility model relates to the technical field of separation equipment, in particular to a rock sorting device. Background Art

[0002] In the development process of oil fields and mines, it is usually necessary to sample and analyze rocks to have a basic understanding of the basic geological conditions of the block. Among them, manual screening is often used for particle size screening of rocks. Specifically, it is graded and screened through sieves of different sizes. It is not only time-consuming and laborious, but also can only be applied to some common scenarios with a small sampling volume. Therefore, those skilled in the prior art have tried to develop some relatively automated devices. For example, Chinese Patent CN206882105U discloses a rock sorting evaluation device that uses centrifugal force and cylinders with multiple different apertures to screen rocks. However, in this patent, there will always be a large number of rock particles in any cylinder. In such a case, not only is a great deal of energy wasted, but also the large number of rock particles in the cylinder will prevent small-particle rocks from entering the next cylinder, resulting in not only low efficiency but also poor separation effect. Summary of the Utility Model

[0003] To solve at least one of the above problems, the utility model provides a rock sorting device with high separation efficiency and good separation effect.

[0004] The technical solution of the utility model is as follows: A rock sorting device includes a housing, a sorting turntable is arranged inside the housing, multiple levels of sorting holes are arranged on the sorting turntable, and the aperture of the sorting holes of each level is larger as the distance from the center of the sorting turntable is farther. A receiving groove is arranged below any level of the sorting holes; a driving motor is also provided, and the driving motor drives the sorting turntable to rotate; a feeding port is arranged at the upper part of the housing, and the feeding port is arranged above the center of the sorting turntable.

[0005] One embodiment of the utility model is that there is an angle of 1-10° between the upper surface of the sorting turntable and the horizontal plane, and the height of the sorting turntable is lower as the distance from the center of the sorting turntable is farther.

[0006] One embodiment of the utility model is that a receiving groove is arranged at the lower part of the edge of the sorting turntable.

[0007] One embodiment of the utility model is that a conical collecting hopper is arranged at the bottom of the receiving groove, and a closable opening is arranged at the bottom of the collecting hopper.

[0008] One embodiment of the present utility model is that a feed channel is provided below the feed inlet. One end of the feed channel away from the feed inlet is disposed above the sorting turntable. An air outlet duct is provided on one side of the feed channel, and a fan is provided on the side of the air outlet duct away from the feed channel.

[0009] Further, a filter screen is provided in the air outlet duct.

[0010] Preferably, a lightweight hopper is provided on the lower side wall of the air outlet duct, and the lightweight hopper is disposed between the filter screen and the feed channel.

[0011] Beneficial effects: The rock sorting device of the present utility model is provided with a sorting turntable with multiple sorting holes, and the driving motor is used to drive the sorting turntable to rotate, thereby applying centrifugal force to the rocks on the sorting turntable. Under the action of the centrifugal force, the rock particles start to move.

Specific Embodiments

[0014] Next, the specific embodiments of the present utility model will be clearly and completely described in conjunction with the examples and the drawings. Obviously, the described examples are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0015] As Figure 1 shown, a rock sorting device includes a housing 1. A sorting turntable 2 is provided inside the housing 1. Multiple sorting holes 3 are provided on the sorting turntable 2. The larger the distance from the center of the sorting turntable 2, the larger the aperture of this level of sorting hole 3. A receiving trough 5 is provided below any level of the sorting hole 3. A driving motor 7 is also provided, and the driving motor 7 drives the sorting turntable 2 to rotate. A feed inlet 9 is provided on the upper part of the housing 1, and the feed inlet 9 is disposed above the center of the sorting turntable 2.

[0016] Specifically, as Figure 1As shown, for the housing 1, it mainly provides corresponding installation positions for components such as the sorting turntable 2, the driving motor 7, the material receiving trough 5, and the feeding port 9. At the same time, the presence of the housing 1 can also reduce the impact of dust in the rocks to be sorted on the environment during the sorting process. Therefore, for the housing 1, most of its side walls, bottom, and top are relatively enclosed.

[0017] The sorting turntable 2 is the main component for sorting rocks in this embodiment. A multi-level sorting holes 3 are densely arranged on the sorting turntable 2. The aperture sizes of the sorting holes 3 at each level are different and are used to sort rock particles of different particle sizes. In order to better classify the sorted rock particles, taking the center of the sorting turntable 2 as a reference, the sorting holes 3 on the sorting turntable 2 are divided into multiple different levels. The farther the distance from the center of the sorting turntable 2, the larger the aperture of the sorting holes 3 at that level, so that the rocks on the sorting turntable 2 are sorted in ascending order of size. When some small particle rocks are sorted, the number of rocks on the sorting turntable 2 decreases, so that subsequent rock particles can be better sorted.

[0018] In order to enable the sorting work to proceed normally, in this embodiment, a driving motor 7 is also provided. The driving motor 7 is connected to the center of the sorting turntable 2 through a bearing 8. When the driving motor 7 rotates, it can drive the sorting turntable 2 to rotate. During the rotation process, a centrifugal force will be generated, so that the rocks to be sorted located in the middle of the sorting turntable 2 move towards the edge of the sorting turntable 2. During the movement process, according to the different particle sizes, the rocks to be sorted are divided into the lower parts of different material receiving troughs.

[0019] For the rocks to be sorted, the current conventional sorting method is to separate them one by one according to the particle size. Therefore, the feeding port is arranged above the center of the sorting turntable 2. During use, the rocks to be sorted coming from the feeding port usually fall into the middle of the sorting turntable 2.

[0020] For the sorting turntable 2, although it can rotate under the drive of the driving motor 7, so that the rocks to be sorted start to move under the action of centrifugal force, however, the rotation speed of the driving motor 7 is difficult to control: if the rotation speed is too fast, the centrifugal force will be too large, and the moving speed of the rocks to be sorted will be too fast, resulting in poor sorting effect; if the rotation speed is too slow, the moving speed of the rocks to be sorted will be slow or basically not move, resulting in great difficulty in actual operation. For this reason, the inventor sets the upper surface of the sorting turntable 2 to a non-horizontal state: there is an angle of 1 - 10° between the upper surface of the sorting turntable 2 and the horizontal plane, and the farther the distance from the center of the sorting turntable 2, the lower the height of the sorting turntable 2. In this case, these rock particles will start to move without a large rotation speed, thus completing the sorting. Preferably, when the angle is between 5 - 8°, the driving motor 4 can maintain a constant speed under a lower rotation speed condition to achieve sorting.

[0021] For the sorting turntable 2, although the sorting holes 3 far away from the center are relatively large in size, in actual use, there will still be larger rocks that are difficult to pass through these sorting holes 3. In order to avoid the accumulation of these large rocks inside the shell 1, in this embodiment, a certain distance is defined between the edge of the sorting turntable 2 and the shell 1, and this distance allows large rocks to pass through. A receiving trough 5 is also provided at the lower part of the edge of the sorting turntable 2. The large rocks discharged from the edge of the sorting turntable 2 will enter the receiving trough 5. Although the farther the distance from the center of the sorting turntable 2, the greater the centrifugal force, the relative rock size is also larger. Therefore, even if the centrifugal force at the edge of the sorting turntable 2 is large, the speed of the rock will not be too fast, and the receiving trough 5 here can work normally.

[0022] In this embodiment, in order to facilitate the collection of rocks in the receiving trough 5, the bottom of the receiving trough 5 is set as a collecting hopper with a conical cross section, and a sealable opening is set at the bottom of the collecting hopper, through which the sorted rocks in the receiving trough 5 can be taken out. The above functions can be achieved by setting corresponding valves, baffles with buckles, and other common operations in the field.

[0023] For the rocks to be sorted, they are mined from the surface or the ground and may contain more impurities, such as dead branches and leaves, etc. These impurities usually have low density and relatively large volume, so they need to be removed before sorting. In order to remove these impurities, in this embodiment, a feed channel 10 is provided at the lower part of the feed port 9, and the end of the feed channel 10 away from the feed port 9 is arranged above the sorting turntable 2, and an air outlet 12 is provided on one side of the feed channel 10, and a fan 11 is provided on the side of the air outlet 12 away from the feed channel 10. Under the action of the fan 11, it will generate suction on the material coming through the feed port 9, and some impurities with lower density will be taken away through the air outlet 12, thereby avoiding these impurities from affecting the subsequent sorting process.

[0024] In order to prevent the impurities from affecting the fan 11, a filter 4 is provided in the air outlet 12. At the same time, the size of the end of the air outlet 12 close to the feed channel 10 is smaller than the size of the end of the air outlet 12 close to the fan 11. In this case, as the cross-sectional area of ​​the air outlet 12 increases, the gas flow rate in the air outlet 12 slows down, so that the impurities settle in the air outlet 12, and the provided filter 4 can further promote the settlement of the impurities.

[0025] In order to collect the impurities settled in the air outlet duct 12, in the present embodiment, a lightweight hopper 13 is further provided on the lower side wall of the air outlet duct 12. The lightweight hopper 13 is provided between the filter screen 4 and the feed channel 10 and is connected to the air outlet duct 12. Therefore, the impurities in the air outlet duct 12 are settled inside the lightweight hopper 13, thereby facilitating treatment.

[0026] For the convenience of placing the device, several legs 6 are further provided at the bottom of the housing 1. Considering the load-bearing problem, these legs 6 can be made of materials with relatively high strength, such as common steel materials, etc.

[0027] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the above-disclosed technical content within the scope of the technical solution of the present invention. However, as long as the content does not depart from the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
