[0055] The following is combined with Figures 1 to 12 The embodiments shown illustrate the technical solution of this utility model:
[0056] This utility model embodiment provides a coal slurry-water separation device for mining, such as... Figures 1 to 4 As shown, it includes: a shell 1, a feeding section 2, a separating cylinder 3, a first driving mechanism 4, a spiral blade assembly 5, a second driving mechanism 6, and a crushing assembly 7;
[0057] The shell 1 has a first separation chamber 101 and a second separation chamber 102; the feed section 2 is connected to the first separation chamber 101; the inner cavity of the separation cylinder 3 is frustum-shaped and is rotatably mounted in the first separation chamber 101 in the horizontal direction; the end with the larger diameter of the inner cavity of the separation cylinder 3 has a first liquid outlet 301 and the end with the smaller diameter has a first coal outlet 302; the first coal outlet 302 is connected to the second separation chamber 102; the first drive mechanism 4 is connected to the separation cylinder 3 and is used to drive the separation cylinder 3 to rotate; the spiral blade assembly 5 includes multiple spiral blades 501 and a first rotating shaft 502, the spiral blade assembly 5 is coaxially rotatably mounted in the inner cavity of the separation cylinder 3, and each spiral blade 501 is arranged sequentially along the axial direction, and the diameter decreases sequentially as the inner cavity diameter of the separation cylinder 3 decreases; the first rotating shaft 502 is partially hollow, and one end of the hollow structure is connected to the feed section 2, and the other end has multiple second liquid outlets 5021; the second drive mechanism 6 is connected to the spiral blade assembly 5 and is used to drive the spiral blade assembly 5 to rotate.
[0058] The rolling assembly 7 is located in the second separation chamber 102 and is used to roll and dewater the coal slag from the first coal outlet 302. The rolling assembly 7 has a rolling channel 701, the width of which gradually decreases from the coal inlet to the coal outlet.
[0059] It is understood that the first drive mechanism 4 and the second drive mechanism 6 can be a combination of AC, servo, or drive motors with belts, gear sets, or chains to drive the separator 3 and the spiral blade assembly 5 to rotate respectively. The direction of rotation of the separator 3 and the spiral blade assembly 5 should be the same, but their speeds should be different. Therefore, the motor speeds of the first drive mechanism 4 and the second drive mechanism 6 should be different.
[0060] In this embodiment, the shell 1 has a first separation chamber 101 and a second separation chamber 102, with different separation components, resulting in different degrees of separation of peat water, and can relatively completely separate the solid and liquid impurities of the peat water; wherein the first separation chamber 101 is equipped with a separation cylinder 3, and the inner cavity of the separation cylinder 3 is frustum-shaped, and a first liquid outlet 301 is opened at the end with the larger diameter.
[0061] The smaller diameter end has a first coal outlet 302. The first drive mechanism 4 is preferably a combination of a drive motor and a belt. Under the high-speed rotation of the separation cylinder 3 driven by the first drive mechanism 4, the less dense liquid is discharged from the first liquid outlet 301, while the denser coal slag is discharged from the first coal outlet 302 into the second separation chamber 102. Furthermore, a spiral blade assembly 5 is coaxially rotatably installed inside the separation cylinder 3, wherein each spiral blade 501 is arranged sequentially along the axial direction, and the diameter decreases sequentially as the inner diameter of the separation cylinder 3 decreases. The first rotating shaft 502 is partially hollow, and one end of the hollow structure is connected to the feed section 2, while the other end has multiple second outlets. The coal slurry-water mixture entering from the feed section 2 enters the separation cylinder 3 through the second liquid outlet 5021. At the same time, the second drive mechanism 6 is preferably a combination of a drive motor and a belt. When the second drive mechanism 6 rotates, the first rotating shaft 502 rotates synchronously, transporting the solid slag in the coal slurry-water to the first coal outlet 302, while the liquid mixture is transported to the first liquid outlet 301. After the solid slag is discharged from the first coal outlet 302, it enters the second separation chamber 102, where it is further crushed and dehydrated by the crushing component 7. The width of the crushing channel 701 in the crushing component 7 gradually decreases, which can further crush the coal slag, so that the solid and liquid in the coal slag can be separated to a large extent.
[0062] The mining coal slurry water separation device provided in this embodiment solves the problem of high slag moisture content and incomplete solid-liquid separation in existing coal slurry water separation equipment by setting up multi-stage separation components. Specifically:
[0063] By setting up the separation cylinder 3 and the spiral blade assembly 5, solid-liquid separation can be achieved under high-speed centrifugation by taking advantage of the different densities of various substances in the coal slurry water. Heavier coal slag and the like are discharged from the first coal outlet 302 to the second separation chamber 102 for further solid-liquid separation, while lighter turbid water is discharged from the shell 1 through the first liquid outlet 301.
[0064] Furthermore, the first rotating shaft 502 in the spiral blade assembly 5 is a hollow structure, with one end connected to the feed section 2 and the other end having multiple second liquid outlets 5021, thereby transporting the coal slurry water to the separation cylinder 3, achieving centrifugal separation while transporting the heavier coal slag to the first coal outlet 302 and the lighter slurry water to the first liquid outlet 301 using the spiral blade assembly 5.
[0065] Furthermore, by setting the rolling assembly 7, the coal slag discharged from the first coal outlet 302 can be rolled to further separate the solid and liquid in the coal slag. The width of the rolling channel 701 gradually decreases from the coal inlet to ensure that the solid-liquid mixture in the coal slag is separated relatively completely under the rolling process, so as to achieve a more thorough solid-liquid separation effect.
[0066] According to the embodiments of this utility model, a coal slurry-water separation device for mining is provided, such as... Figure 4 and Figure 5 As shown, the feeding section 2 includes a feeding hopper 201 and a feeding pipe 202. One end of the feeding hopper 201 is connected to the feeding pipe 202, and the other end of the feeding pipe 202 is connected to the first separation chamber 101. A filter screen 2011 is provided at the opening of the feeding hopper 201.
[0067] It is understandable that the cavity shape of the feed hopper 201 can be a single conical structure, or a combination structure of a frustum, cube, solid, and prism with a cone, which can achieve feeding while also having a certain buffering effect, ensuring that the feeding speed is slightly lower than the separation speed of the device.
[0068] In this embodiment, the feed hopper 201 is preferably a combination of a cube and a cone to ensure that the coal slurry water enters the device as much as possible without large-area spillage. At the same time, one end of the feed pipe 202 is connected to the feed hopper 201, and the other end is connected to the first separation chamber 101 to ensure that the coal slurry water enters the first separation chamber 101 from the feed section 2 to achieve subsequent solid-liquid separation. A filter screen 2011 is provided at the opening of the feed hopper 201 to initially separate larger coal slag, metal blocks or other coal ore, preventing large coal slag and other materials from entering the device and causing blockages.
[0069] According to the embodiments of this utility model, a coal slurry-water separation device for mining is provided, such as... Figure 3 and Figure 6 As shown, the compaction assembly 7 includes:
[0070] There are multiple rolling rollers 702 arranged in parallel to each other and rotatably installed in the second separation chamber 102. The multiple rolling rollers 702 are divided into at least two groups.
[0071] The filter belt 703 has at least two belts, each fitted onto a roller set;
[0072] The third drive mechanism 704 is connected to the crushing wheel 702 in a drive connection.
[0073] Among them, a rolling channel 701 is formed between the filter belts 703 of adjacent groups, and the rolling wheels 702 of adjacent groups rotate in opposite directions.
[0074] In this embodiment, after the coal slag enters the second separation chamber 102 through the first coal outlet 302, it passes through the inclined plate between the channel and the rolling assembly 7, allowing the coal slag to smoothly enter the rolling assembly 7. A filter belt 703 is sleeved between the multiple rotating rolling wheels 702. The filter belt 703 is preferably made of PP, which has good corrosion resistance and rapid water drainage performance, so that the liquid in the coal slag can be quickly separated from the filter belt 703 during the rolling process. A rolling channel 701 is formed between adjacent groups of filter belts 703. Under the drive of the third driving mechanism 704, the rolling wheels 702 rotate in opposite directions to realize the rolling of the coal slag by the filter belt 703 and to slowly transport the coal slag to the coal outlet.
[0075] According to the embodiments of this utility model, a coal slurry-water separation device for mining is provided, such as... Figure 6 As shown, the filter belt 703 is capable of draining water, and has a mesh size of 80-150 mesh and a pore size range of 180-120 micrometers.
[0076] In this embodiment, the filter press belt 703 has multiple sieve holes with a mesh size of 80-150 mesh and a pore size range of 180 micrometers-120 micrometers. While having a good drainage effect, it can also trap solid coal slag, preventing large coal slag particles from passing through the sieve holes and preventing secondary fusion. Fine particles will adhere to the filter press belt 703, ultimately achieving a relatively good solid-liquid separation effect.
[0077] According to the embodiments of this utility model, a coal slurry-water separation device for mining is provided, such as... Figure 6 and Figure 7 As shown, the rolling wheel 702 includes an outer cylinder 7021 and a second rotating shaft 7022, wherein the outer cylinder 7021 has multiple mesh holes, and the second rotating shaft 7022 is coaxially arranged with the outer cylinder 7021 through a bracket.
[0078] In this embodiment, the rolling wheel 702 consists of an outer cylinder 7021 and a second rotating shaft 7022. The outer cylinder 7021 is provided with multiple mesh holes. When the third driving mechanism 704 drives the second rotating shaft 7022 to rotate, the outer cylinder 7021, which is coaxially arranged with it through the bracket, will also rotate synchronously. The mesh holes on the outer cylinder 7021 reduce the weight of the outer cylinder 7021 on the one hand, and allow the water squeezed out by the rolling wheel 702 to pass smoothly through the outer cylinder 7021 after passing through the filter belt 703. Ultimately, the drained water and coal slag are in different chambers, ensuring good solid-liquid separation of coal slurry as much as possible.
[0079] According to the embodiments of this utility model, a coal slurry-water separation device for mining is provided, such as... Figure 3 , Figure 8 and Figure 9 As shown, the separator 3 has a third rotating shaft 303;
[0080] The third rotating shaft 303 is coaxially arranged with the first rotating shaft 502, and the third rotating shaft 303 is located near the first liquid outlet 301; the third rotating shaft 303 is a hollow structure, and a first sealed bearing 8 is provided at the connection between the separation cylinder 3 and the shell 1.
[0081] In this embodiment, the separator 3 has a third rotating shaft 303. The first driving mechanism 4 is connected to the separator 3 via a belt, driving the third rotating shaft 303 of the separator 3 to rotate, thereby driving the separator 3 to rotate. There is a first sealing bearing 8 between the separator 3 and the housing 1, so that the separator 3 can rotate inside the housing 1. The first sealing bearing 8 can ensure that the sewage discharged from the first outlet 301 will not leak from the rotating shaft.
[0082] According to the embodiments of this utility model, a coal slurry-water separation device for mining is provided, such as... Figure 3 , Figure 8 , Figure 9 and Figure 10 As shown, a second sealed bearing 9 is provided between the first rotating shaft 502 and the third rotating shaft 303, and the second sealed bearing 9 is provided in the hollow structure of the third rotating shaft 303. The first rotating shaft 502 is rotatably disposed in the separation cylinder 3, and a third sealed bearing 10 is provided between the first rotating shaft 502 and the separation cylinder 3.
[0083] In this embodiment, the second sealed bearing 9 ensures that the wastewater after preliminary solid-liquid separation will not leak from between the first rotating shaft 502 and the third rotating shaft 303, while the third sealed bearing 10 enables the first rotating shaft 502 to rotate inside the separation cylinder 3, and also ensures that the wastewater after preliminary solid-liquid separation will not leak from the connection between the first rotating shaft 502 and the separation cylinder 3. Through the setting of each sealed bearing, the device can operate normally, and at the same time, wastewater will not leak from the connection between each bearing.
[0084] According to the embodiments of this utility model, a coal slurry-water separation device for mining is provided, such as... Figure 7 and Figure 11 As shown, the third drive mechanism 704 includes:
[0085] Drive motor 7041;
[0086] The drive belt 7042 connects the adjacent second rotating shafts 7022 between each set of rolling wheels, and the drive belts 7042 in the rolling wheel set are distributed in an S-shape.
[0087] The drive motor 7041 is belt-driven connected to its adjacent second rotating shaft 7022.
[0088] It is understandable that the third drive mechanism 704, like the first drive mechanism 4 and the second drive mechanism 6, can be a combination of servo or drive motor with belt, gear or chain, which can drive the second rotating shaft 7022 to rotate.
[0089] In this embodiment, the third drive mechanism 704 is preferably a combination of a drive motor 7041 and a transmission belt 7042. The drive motor 7041 is connected to the second shaft 7022 of the adjacent rolling wheel 702 by belt drive, and the adjacent second shafts 7022 in the rolling wheel group are connected by the transmission belts 7042. The transmission belts 7042 in the rolling wheel group are distributed in an S-shape. Therefore, only one drive motor 7041 is needed to drive the rotation of the second shaft 7022 in the rolling wheel group.
[0090] According to the embodiments of this utility model, a coal slurry-water separation device for mining is provided, such as... Figure 3 and Figure 12 As shown, a retaining ring 11 is provided in the first separation chamber 101 near the first coal outlet 302. The retaining ring 11 abuts against the shell 1, and the separation cylinder 3 passes through the retaining ring 11. There is a gap between the retaining ring 11 and the separation cylinder 3. The retaining ring 11 divides the first separation chamber 101 into a dewatering zone 1011 and a slag discharge zone 1012.
[0091] The slag discharge zone 1012 is connected to the second separation chamber 102.
[0092] In this embodiment, the baffle ring 11 ensures that the dewatering zone 1011 and the slag discharge zone 1012 do not interfere with each other. That is, due to the rotation of the separation cylinder 3, the sewage separated from the first liquid outlet 301 may accumulate in the dewatering zone 1011 near the baffle ring 11. The baffle ring 11 ensures that the sewage will not be mixed with the coal slag at the first coal outlet 302, ensuring that the initial solid-liquid separation of coal slurry is more thorough and will not affect the solid-liquid separation effect of the device.
[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
