Description

Technical Field

[0001] The utility model relates to the field of barite, and more specifically, to a barite tailing separation device. Background Art

[0002] Barite is the most common mineral of barium, with its composition being barium sulfate. It is produced in low-temperature hydrothermal veins, such as quartz-barite veins, fluorite-barite veins, etc., and is often symbiotic with galena, sphalerite, chalcopyrite, cinnabar, etc. Barite can also be produced in sedimentary rocks, appearing in the form of nodules, mostly existing in sedimentary manganese deposits and muddy and sandy sedimentary rocks in shallow seas. In the residual clay cover layer of weathering residual deposits, it often occurs in nodular and massive forms. Before using barite tailings, they need to be screened and separated by a separation device so that barite tailings with different particle sizes can be separated and collected for further use. However, the mesh size of the separation net in the existing separation device is fixed, making it inconvenient to separate barite tailings in different particle size layers. Moreover, when the separation net is damaged, it is inconvenient to replace, bringing inconvenience to the work. For this reason, application number: CN201921097153.7 discloses a barite tailing separation device, whose structure includes a protective cover, a partition board, a separation net board, and a replacement structure. By setting the replacement structure at the left end inside the box, pulling the limit rod downward makes the limit spring compress downward under pressure, and inserting the separation net board into the chute. Pushing the separation net board drives the positioning block into the positioning groove, then inserting the square block into the chute, and then pushing the insertion rod to make the connecting rod and the square block enter the convex groove. Then rotating the insertion rod 90° makes the left end face of the square block closely adhere to the inner left end face of the convex groove. At the same time, canceling the pressure on the limit rod enables the limit rod to move upward under the elastic force of the limit spring and enter the limit groove for fixation, achieving the beneficial effect of replacing separation net boards with different pore sizes according to the needs of the separated particle sizes, and having a high replacement efficiency, bringing convenience to the work.

[0003] However, the above solution still has certain defects. The inventor has found through research that in the above solution, by setting a structure for facilitating the replacement of the separation net board, it is possible to replace the separation net board with different pore sizes according to the needs of the separated particle sizes. However, this separation method requires replacing the separation net board multiple times and repeating the separation work to achieve, which is relatively time-consuming and laborious, and repeated disassembly and assembly may also affect the stability and service life of the overall structure.

Detailed implementation manners

[0022] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a barite tailings separation device, including a multi - stage filtering component 1. The multi - stage filtering component 1 includes a number of filtering cylinder mechanisms connected end to end in sequence. Each filtering cylinder mechanism includes two coaxially arranged port mounting rings 101. A filter mesh cylinder 102 is connected between the opposite side surfaces of the two port mounting rings 101. The filter hole diameters of a number of filter mesh cylinders 102 are all different and are distributed in sequence from small to large according to the filter hole diameters. A rotating shaft 103 is arranged inside the filter mesh cylinder 102, and a spiral feeding plate 104 distributed along its extending direction is arranged on the outer wall of the rotating shaft 103. The corresponding ends of the rotating shafts 103 in adjacent two filtering cylinder mechanisms are fixedly sleeved with gears 107 respectively, and the two gears 107 are meshed and connected. The multi - stage filtering component is connected to a driving device, and a corresponding storage bin 2 is fixedly connected below each filtering cylinder mechanism.

[0024] Please refer to Figure 3 and Figure 4 , one end of a bracket is fixedly connected to the outer wall of one side of each port mounting ring 101, and the other ends of the two corresponding brackets are respectively fixedly connected to both sides of the top surface of the corresponding storage bin 2. In addition, a storage bin 2 for collecting and storing the raw materials that have completed the multi - stage screening and separation work is also arranged at the outlet of the filtering cylinder mechanism at the last stage.

[0025] By fixedly connecting each filtering cylinder mechanism with the corresponding storage bin 2, the barite with the corresponding particle size screened out by the filtering cylinder mechanism can be collected and stored by using the storage bin 2. A door is also arranged on each storage bin 2, which is convenient for collecting barite.

[0026] Further, an installation ring 105 is coaxially arranged inside each port installation ring 101. The installation ring 105 is fixedly connected to the inner wall of the corresponding port installation ring 101 through a number of connecting rods 106 evenly distributed in a ring shape on the outer wall. Both ends of each rotating shaft 103 are rotatably connected to the corresponding installation ring 105.

[0027] Each rotating shaft 103 is rotatably connected inside the corresponding two port installation rings 101 and the filter cylinder 102 through the installation ring 105. Through the drive of the drive device and the transmission connected by meshing with the gear 107, all the rotating shafts 103 in the filter cylinder mechanisms will rotate synchronously, thereby driving all the spiral pushing plates 104 to rotate independently in the corresponding filter cylinders 102 to complete the conveying of the raw materials.

[0028] Further, the diameter of the spiral pushing plate 104 corresponds to the inner diameter of the filter cylinder 102.

[0029] The outer wall of the spiral pushing plate 104 being in contact with the inner wall of the filter cylinder 102 can ensure the stability and efficiency of material conveying, increase the residence time of the raw materials inside the filter cylinder 102, and thus ensure the screening efficiency for barite with different particle sizes.

[0030] Further, several filter cylinder mechanisms are inclinedly distributed and the height gradually decreases from one side to the other side.

[0031] By inclining several filter cylinder mechanisms, the raw materials are affected by gravity. Combining with the pushing of the raw materials by the spiral pushing plate 104 can improve the speed of the raw materials passing through each filter cylinder mechanism while ensuring the screening and filtering effect, and increase the barite separation speed.

[0032] Further, on one side surface of the port installation ring 101 of each filter cylinder mechanism facing the adjacent filter cylinder mechanism with a lower height, a guiding plate 108 is provided, and the guiding plate 108 extends into the interior of the corresponding port installation ring 101 of the filter cylinder mechanism with a lower height.

[0033] By providing the guiding plate 108 on one end surface of each filter cylinder mechanism, the raw materials after screening out barite with the corresponding particle size can be guided into the next-level filter cylinder mechanism for further screening and separation work, reducing the situation where the raw materials fall from the connection between adjacent two-level filter cylinder mechanisms.

[0034] Please refer to Figures 1 to 3 , all the storage bins 2 are fixedly installed on the inner wall of the bottom of a U-shaped frame 3, and a baffle 301 corresponding to the inclination angle of the multi-stage filtering assembly 1 is provided at one end of the frame 3.

[0035] Fixing and connecting each stage of the filter cartridge mechanism together with the storage bin 2 through the frame 3 can ensure the stability during use. Setting the baffle plate 301 can block the raw materials discharged at the end, preventing the raw materials from flying out and causing danger, and improving the safety during use.

[0036] Furthermore, a feed hopper 5 is provided at the other end of the frame 3, and the bottom end of the feed hopper 5 extends to the corresponding port mounting ring 101 in the filter cartridge mechanism closest to it.

[0037] By providing the feed hopper 5 at the higher end of the frame 3, feeding materials into the first-stage filter cartridge mechanism by using the feed hopper 5 can improve the convenience during the use process.

[0038] Furthermore, the driving device is a motor 4, and the motor 4 is fixedly installed on one side surface of the frame 3, and one end of the output shaft of the motor 4 is fixedly connected to one end of the rotating shaft 103 in the filter cartridge mechanism closest to it.

[0039] The motor 4 drives the rotating shaft 103 in the first-stage filter cartridge mechanism to rotate. The first-stage rotating shaft 103 and the subsequent rotating shafts 103 are all sequentially meshed and connected together through gears 107 for synchronous transmission, so that all the spiral pushing plates 104 perform synchronous pushing of materials.

[0040] Working principle: Add raw materials into the first-stage filter cartridge mechanism at the highest position through the feed hopper 5, and start the motor 4. The motor 4 drives the rotating shaft 103 in the first-stage filter cartridge mechanism to rotate. The first-stage rotating shaft 103 and the subsequent rotating shafts 103 are all sequentially meshed and connected together through gears 107 for synchronous transmission, so that all the spiral pushing plates 104 perform synchronous pushing of materials. The aperture of the filter mesh cylinder 102 in each stage of the filter cartridge mechanism gradually becomes larger from high to low according to the height. The raw materials are screened and separated in each stage of the filter mesh cylinder 102 under the push of the spiral pushing plates 104. The barite particles corresponding to the aperture are gradually distributed and collected in the corresponding storage bin 2, thereby completing the multi-stage screening and separation of the tailings barite. One separation process can classify and collect and store barite with different particle sizes, greatly improving the separation efficiency of barite.

[0041] It should be noted that the specific model and specification of the motor 4 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0042] The power supply and principle of the motor 4 are clear to those skilled in the art and will not be elaborated here.

[0043] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
