Detailed Description
In order to make the technical solutions and advantages of the present invention more apparent, exemplary embodiments of the present invention are described in further detail below with reference to the accompanying drawings. It is clear that the described embodiments are only a part of the embodiments of the invention, and not an exhaustive list of all embodiments. And the embodiments and features of the embodiments may be combined with each other without conflict.
The embodiment of the invention provides a heavy-medium shallow slot separator. As shown in fig. 1, the heavy-medium shallow slot separator comprises a shallow slot separator body 16, an upward flow material inlet 17, a horizontal flow material inlet 15, an upward flow medium storage 1 and a horizontal flow medium storage 8. The ascending inlet 17 is provided in communication with the wall of the shallow trench sorter body 16. The horizontal feed inlet 15 is also arranged in communication with the wall of the shallow slot separator body 16. The upflow media storage 1 is used to store an upflow media. The upflow medium reservoir 1 is connected to the upflow inlet port 17 via an upflow medium pipe so as to feed the upflow medium into the shallow trench sorter body 16. And a horizontal streaming medium storage 8 is used for storing horizontal streaming medium. The horizontal flow medium reservoir 8 is connected in communication with the horizontal inflow port 15 through a horizontal flow medium pipe to supply the horizontal flow medium into the shallow groove separator body 16.
In the working process, the upflow medium storage 1 supplies upflow medium to the shallow groove separator body 16, which is used for ensuring the stability and the uniformity of suspension liquid in the shallow groove separator body 16 and playing the roles of dispersing materials and keeping the buoyancy of the materials. The horizontal flow medium storage 8 supplies horizontal flow medium to the shallow groove separator body 16, is used for forming horizontal medium flow moving from the feeding end to the discharging end and plays a role in transporting floating materials. In the present application, the upflow media reservoir 1 for the upflow media supply and the horizontal flow media reservoir 8 for the horizontal flow media supply are independent of each other and do not interfere with each other in supplying the corresponding media flows, and the density stability of one, for example, upflow media, is not affected by adjusting the flow rate of the other, for example, horizontal flow media. In addition, because the upward flow medium storage 1 and the horizontal flow medium storage 8 are independent, the respective densities of the horizontal flow medium and the upward flow medium can be optimized and configured, and fine control on separation is realized, so that the parameters of at least one medium can be conveniently adjusted when different granularities and different minerals are faced, the use range of the heavy medium shallow slot separator is improved, and the separation precision is ensured.
In a specific embodiment, the upflow media conduits include an upflow main 4, an upflow main solenoid valve 5, and an upflow media pump 2. One end of the upflow main pipe 4 is connected to the upflow medium reservoir 1 as a pipe for carrying the upflow medium. The upflow main pipe electromagnetic valve 5 is provided on the upflow main pipe 4. The upflow medium pump 2 is driven by an upflow medium pump frequency modulation motor 3 and is used for pumping the upflow medium in the upflow medium storage 1 into an upflow main pipe 4. Through the arrangement, the flow of the upflow medium in the upflow main pipe 4 can be regulated and controlled through the upflow main pipe electromagnetic valve 5, the upflow medium pump 2 and the upflow medium pump frequency modulation motor 3, so that the use requirement is met, and the accurate regulation and control is realized. And, in the adjusting process, the horizontal flow medium is not influenced.
The upward inflow port 17 is plural, for example, four, as shown in fig. 2. The specific amount of the upward flow into the material port 17 can be modified in actual production, and the number can be increased if more precise control is desired. The upward flow branch pipes 6 are provided so as to communicate with each of the upward flow inlet ports 17 and the upward flow main pipe 4. And an upward flow branching solenoid valve 7 is provided in each upward flow branching pipe 6. The flow of the medium flow in the upflow separator 6 can be conveniently controlled by the upflow separator electromagnetic valve 7, and the fine operation is improved.
An upward flow connecting piece 18 is arranged between the upward flow feeding port 17 and each upward flow distributing pipe 6 in a communicating manner. The upflow connector 18 has an upflow connector barrel 181 provided on the bottom wall of the shallow trench sorter body 16, and an upflow cone 182 provided between the upflow connector barrel 181 and the corresponding upflow distributor 6. The flow area of the upward flow conical cylinder 182 gradually increases in the direction from the upward flow distributing pipe 6 to the upward flow connecting cylinder 181. The arrangement mode is beneficial to the uniform transmission of the upflow media, and the sorting effect is ensured. In the arrangement, the upflow distributing pipes 6 and the upflow main pipes 4 are arranged in the vertical direction as much as possible, and for example, the angles between the upflow distributing pipes 6 and the upflow main pipes 4 and the horizontal direction are all 75 to 90 degrees. This arrangement is used to ensure the flow direction of the upflow media and prevent material accumulation.
Similarly, the horizontal flow medium pipeline comprises a horizontal flow main pipe 11, a horizontal flow main pipe electromagnetic valve 12 and a horizontal flow medium pump 9. One end of the horizontal flow main pipe 11 is connected to the horizontal flow medium reservoir 8 to serve as a pipe for carrying the horizontal flow medium. The horizontal flow main pipe electromagnetic valve 12 is arranged on the horizontal flow main pipe 11. The horizontal flow medium pump 9 is driven by a horizontal flow medium pump frequency modulation motor 10 and is used for pumping the horizontal flow medium in the horizontal flow medium storage 8 into the horizontal flow main pipe 11. Through the arrangement, the flow of the horizontal flow medium in the horizontal flow main pipe 11 can be regulated and controlled through the horizontal flow main pipe electromagnetic valve 12, the horizontal flow medium pump 9 and the horizontal flow medium pump frequency modulation motor 10, so that the use requirement is met, and accurate regulation and control are realized. And in the adjusting process, the upflow medium is not influenced.
The horizontal inflow port 15 is plural, for example, three, four or more. And a horizontal flow branch pipe 13 is arranged between each horizontal flow inlet 15 and the horizontal flow main pipe 11 in a communicating manner. And a horizontal flow branch solenoid valve 14 is provided on each horizontal flow branch 13. The flow of the horizontal medium flow in the horizontal flow branch pipe 13 can be conveniently controlled through the horizontal flow branch pipe electromagnetic valve 14, and the fine operation is improved.
In actual use, the density of the upflow media in the upflow media storage 1 is the same as or different from the density of the horizontal flow media in the horizontal flow media storage 8. Even if the density of the ascending flow medium in the ascending flow medium storage 1 is the same as the density of the horizontal flow medium in the horizontal flow medium storage 8, the two storages 1 and 8 do not interfere with each other, and the density stability of one ascending flow medium, for example, is not affected by adjusting the flow rate of the other horizontal flow medium. The densities can be different, so that horizontal flow media and ascending flow media with different densities can be configured according to the characteristics of the sorted minerals, such as coal, in production, and fine control on sorting is realized. For example, when the overall density of the sorted coal sample is high, the density of the upflow medium can be increased without adjusting the density of the horizontal flow medium, so that the sorting effect is ensured, and the consumption of the medium is reduced.
The application also relates to a sorting method according to the heavy-medium shallow slot sorting machine.
Specifically, when the mass content of the high-density material is increased by 10%, the flow rate of the horizontal medium flow is increased by 5-10%. For coal samples, the high-density material is gangue, and when the mass content of the gangue is increased by 10%, the flow rate of the horizontal medium flow is increased by 7% for example. This arrangement avoids blockage caused by the accumulation of spoil below the interior of the shallow trench separator body 16.
When the mass content of the fine-grained matter with the grain diameter of less than or equal to 6mm is increased by 10%, the flow rate of the ascending medium flow is reduced by 10-20%, for example by 15%. The arrangement can ensure the influence of the hydraulic force of the suspension on the sorted materials such as coal samples, and improve the sorting effect.
When the density is 1.6-1.8g/cm3InWhen the mass content of the intermediate density stage is more than or equal to 10 percent, the ascending flow adopts a pulsating medium flow. The ascending pulsating medium flow can improve the effect of coal sample layering according to density and improve the separation effect of medium density grade.
The invention realizes the fine regulation and control of the medium density and the flow field of the heavy-medium shallow groove separator, strengthens the separation process of materials with different granularity levels, realizes the high-efficiency separation of wide-granularity-level materials, particularly fine-granularity-level materials, and has the advantages of wide material granularity, strong adaptability, large handling capacity, high separation precision and the like.
