Description

Technical Field

[0001] This utility model relates to the field of coal washing technology, specifically a flow stabilizer for reducing the consumption of heavy medium suspensions during washing. Background Technology

[0002] In the media circulation system of coal washing and beneficiation operations, a flow stabilizer is usually used to buffer the media flowing into the media tank, reduce the impact of the media on the inside of the media tank, and reduce the foam generated inside the media tank due to the impact of the media.

[0003] In existing coal washing plants, the flow stabilization box is equipped with a filter plate. The washed coal medium is transported to the flow stabilization box through pipelines. After being filtered by the filter plate, the medium enters the bottom of the flow stabilization box and is discharged into the mixing tank. The existing flow stabilization box not only serves as a buffer for the medium but also filters the coal lumps in the medium. However, the flow stabilization box uses the filter plate to filter the coal lumps in the medium, causing a large amount of coal lumps to accumulate on the top of the filter plate. This eventually leads to blockage of the filter plate, affecting the filtration of the medium and increasing the load on the filter plate, which in turn causes the filter plate to bend and deform.

[0004] Therefore, when a certain amount of coal lumps accumulate on the filter plate, it is necessary to clean the coal lumps on the filter plate. The existing method of cleaning the filter plate in the flow stabilization box requires workers to enter the flow stabilization box for cleaning. However, since there are small amounts of harmful gases such as carbon monoxide, sulfur dioxide, and hydrogen sulfide in the medium after coal washing, these harmful gases will evaporate in small amounts and accumulate in the flow stabilization box after entering it. Therefore, workers entering the flow stabilization box for cleaning is not only difficult to operate, but also poses a risk of inhaling harmful gases.

[0005] Therefore, a flow stabilizer is proposed to address the above problems and reduce the consumption of heavy medium suspension washing media. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: 1. A flow stabilizing box for reducing the washing and screening of heavy medium suspension, comprising a flow stabilizing box body; a partition is fixedly connected to the middle of the inner cavity of the flow stabilizing box body; a plurality of filter elements are uniformly arranged in the partition; a transmission chain is provided on the top of both sides of the inner cavity of the flow stabilizing box body; a motor capable of driving the transmission chain to run in a ring is provided on the side of the flow stabilizing box body; a vertically downward support rod is bolted to the side of the two transmission chains that are close to each other; a crossbar capable of scraping coal blocks to the top surface of the filter element is installed at the bottom between the two support rods.

[0008] Preferably, a liquid inlet is fixedly connected to one end of the top surface of the flow stabilizer; a liquid outlet is fixedly connected to the other end of the bottom surface of the flow stabilizer; and an inspection port is provided at the end of the top surface of the flow stabilizer away from the liquid inlet.

[0009] Preferably, the bottom surface of the partition plate near the motor has a slot; the bottom surface of the partition plate near the motor is fitted with a discharge slide on the outside of the slot; the end of the discharge slide away from the motor is fixed with a discharge port, and the discharge port penetrates the side wall of the flow stabilizer box 1.

[0010] Preferably, a spiral blade is rotatably mounted inside the discharge chute; the shaft of the spiral blade is fixedly connected to the output shaft of the motor.

[0011] Preferably, annular guide rails are fixedly connected to both sides of the inner cavity of the flow stabilizer box and below the transmission chain; a slide rod is slidably installed inside the support rod; a limiting rod that slides with the annular guide rail is fixedly connected to the side of the slide rod; and the end of the crossbar is bolted to the bottom of the slide rod.

[0012] Preferably, the transmission chain is hinged to a connector on the side of the inner cavity of the flow stabilizer box; the top of the support rod is hinged to the bottom of the connector.

[0013] Preferably, a scraper that can contact the top surface of the filter element is bolted to the outer side of the crossbar.

[0014] Preferably, the outer periphery of the partition has multiple sets of countersunk holes evenly formed; the bottom surface of the outer periphery of the partition is bolted to the inner wall of the flow stabilizer box by multiple angle irons.

[0015] Preferably, a top cap is inserted into the top of the countersunk hole on the outer periphery of the partition.

[0016] The advantages of this utility model are:

[0017] 1. The flow stabilizing box for reducing media consumption in heavy medium suspension washing, as described in this utility model, is equipped with baffles and filters. When the medium enters the flow stabilizing box, it falls vertically downward onto the baffles, meaning the medium concentrates its impact on a portion of the filters. This causes the filters in that portion to be subjected to a huge impact force, and due to the impact of the medium, coal lumps are more likely to get stuck in the filter holes of that portion of the filters, and the coal lumps are stuck to a greater depth and are difficult to remove. In this case, simply replacing that portion of the filters with other filters with lower filtration pressure can ensure the stable operation of the flow stabilizing box for a certain period of time.

[0018] 2. The flow stabilizing box for reducing media consumption in heavy medium suspension washing as described in this utility model is equipped with a transmission chain, a motor, a support rod, and a crossbar. The transmission chain drives the support rod and crossbar to perform periodic movements. Specifically, from the initial position to the final position, the crossbar descends to move the coal block, and from the final position to the initial position, the crossbar rises without contacting the coal block and returns. This cleans the coal block on the top surface of the baffle and filter element to the top of one end of the baffle, facilitating cleaning work for the staff. Moreover, the staff does not need to enter the interior of the flow stabilizing box, making the cleaning operation convenient and avoiding the inhalation of harmful gases.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0032] like Figures 1 to 9 As shown, a flow stabilizing box for reducing the washing and screening of heavy medium suspension includes a flow stabilizing box body 1; a partition 2 is fixedly connected to the middle of the inner cavity of the flow stabilizing box body 1; a plurality of filter elements 3 are evenly arranged inside the partition 2; a transmission chain 4 is provided on the top of both sides of the inner cavity of the flow stabilizing box body 1; a motor 9 is provided on the side of the flow stabilizing box body 1, which can drive the transmission chain 4 to run in a ring; a vertically downward support rod 5 is bolted to the side of the two transmission chains 4 that are close to each other; a crossbar 6 is installed at the bottom between the two support rods 5, which can scrape coal blocks to the top surface of the filter element 3.

[0033] In practice, the current stabilizing box 1 is equipped with a sealing cover; the sealing cover is fixed to the current stabilizing box 1 by bolts, and a sealing gasket is provided between the sealing cover and the current stabilizing box 1.

[0034] The partition plate 2 has multiple square grooves evenly provided for installing the filter element 3, and the bottom inner circle of the square groove is provided with a boss; the bottom of the partition plate 2 is fixedly connected with a grid-like reinforcing rib distributed around the square groove, and the filter element 3 has a square structure, and the outer side of the filter element 3 matches the inner side of the square groove of the partition plate 2, and the filter element 3 can be blocked by the boss on the inner side of the square groove; the outer side of the filter element 3 is fixedly connected with a protrusion for positioning and fixing, and the inner side of the square groove of the partition plate 2 is provided with a groove that matches the protrusion.

[0035] When installing the filter element 3 into the square groove of the partition plate 2, simply place the filter element 3 into the square groove of the partition plate 2 and press it down firmly so that the outer protrusion of the filter element 3 is inserted into the groove on the inner side of the square groove, and the filter element 3 is installed in place.

[0036] When the medium enters the flow stabilizing chamber 1, it falls vertically downwards onto the baffle 2. This means the medium will concentrate its impact on a portion of the filter elements 3, subjecting those elements to tremendous impact force. Furthermore, due to this impact, coal lumps are more likely to become lodged deep within the filter holes of these elements, making them difficult to remove. In this case, simply replacing these filter elements 3 with others that have lower filtration pressure will ensure the stable operation of the flow stabilizing chamber 1 for a certain period. Alternatively, these filter elements 3 can be removed, backwashed with a high-pressure water gun, and then replaced and maintained. Moreover, the assembly of multiple filter elements 3 with the baffle 2 reduces the area of ​​the filter elements 3, effectively ensuring their strength and reducing deformation caused by the impact of the medium.

[0037] Both ends of the transmission chain 4 are fitted with sprockets 7, and a rotating rod 8 that rotates through the side wall of the flow stabilizer box 1 is fixedly connected to the middle of the sprocket 7. A bracket is fixedly connected to one end of the flow stabilizer box 1. The motor 9 is bolted to the bracket. A connecting rod 10 is rotatably mounted on the top end face of the flow stabilizer box 1 near the motor 9 via a bearing seat. The output shaft of the motor 9 and the end of the connecting rod 10 near the motor 9 are driven by a belt. The two ends of the connecting rod 10 are also driven by belts to the two corresponding rotating rods 8 on both sides.

[0038] When the flow stabilizer box 1 is running normally, the support rods 5 and crossbars 6 on both sides are located at one end inside the flow stabilizer box 1. This is the initial position. Since the support rods 5 are located at the upper half of the transmission chain 4, the crossbars 6 at the bottom of the support rods 5 are disengaged from the top surface of the partition 2.

[0039] When a certain amount of coal accumulates on the top surface of the baffle 2 and filter element 3, and cleaning is required, the control motor 9 starts. Through belt drive, it drives the rotating rod 8 to rotate, and then through belt drive, it starts the rotating rods 8 on both sides to rotate synchronously, driving the sprocket 7 to rotate. This, in turn, drives the transmission chains 4 on both sides to rotate synchronously. When the transmission chain 4 drives the support rod 5 past the sprocket 7, the top of the support rod 5 moves to the lower half of the transmission chain 4, causing the height of the support rod 5 and the crossbar 6 to decrease, allowing the crossbar 6 to contact the coal on the top of the filter element 3. The drive chain 4 continues to move the support rod 5 and the crossbar 6 towards the other end of the flow stabilizing box 1. The crossbar 6 pushes the coal block towards the end of the flow stabilizing box 1, that is, the top end of the partition 2. When the drive chain 4 moves the support rod 5 and the crossbar 6 to another sprocket 7, which is the end position, the drive chain 4 carries the top of the support rod 5 around the sprocket 7, so that the top of the support rod 5 moves to the upper half of the drive chain 4, so that the crossbar 6 moves upward away from the top surface of the partition 2. The drive chain 4 drives the support rod 5 and the crossbar 6 back to the initial position.

[0040] The transmission chain 4 drives the support rod 5 and the crossbar 6 to perform periodic movements; that is, from the initial position to the end position, the crossbar 6 descends to push the coal block to move, and from the end position to the initial position, the crossbar 6 rises to return without contacting the coal block; thus, the coal block on the top surface of the baffle 2 and the filter element 3 is cleared to the top of one end of the baffle 2, which facilitates the cleaning work of the staff, and the staff does not need to enter the interior of the flow stabilizing box 1. Not only is the cleaning operation convenient, but it also avoids the staff inhaling harmful gases.

[0041] like Figure 1 As shown, a liquid inlet 11 is fixedly connected to one end of the top surface of the flow stabilizing box 1; a liquid outlet 12 is fixedly connected to the other end of the bottom surface of the flow stabilizing box 1; and an inspection port 13 is provided at the end of the top surface of the flow stabilizing box 1 away from the liquid inlet 11.

[0042] In specific implementation, the liquid inlet 11 is fixed to the top surface of the sealing cover of the flow stabilizer 1, and the liquid inlet 11 is used to introduce the washed coal medium into the interior of the flow stabilizer 1, while the liquid outlet 12 is used to discharge the medium at the bottom of the flow stabilizer 1. Because the liquid inlet 11 and the liquid outlet 12 are staggered, the medium flows a longer distance inside the flow stabilizer 1, thereby effectively reducing foam in the medium, which is beneficial to the subsequent mixing in the mixing tank.

[0043] The top surface of the access port 13 is hinged with a top cover; the access port 13 is used for maintenance work by personnel.

[0044] The initial position of the support rod 5 and the crossbar 6 is located at one end of the flow stabilizing box 1 near the liquid inlet 11, and the end position of the support rod 5 and the crossbar 6 is located at one end of the flow stabilizing box 1 near the inspection port 13.

[0045] When the crossbar 6 pushes the coal block to one end of the top surface of the partition 2, that is, the end of the partition 2 near the inspection port 13, the staff can clean the coal block through the inspection port 13 without entering the interior of the flow stabilizing box 1, thus protecting the safety of the staff.

[0046] like Figures 2 to 4 As shown, a slot 14 is provided on the bottom surface of the partition plate 2 near the motor 9; a discharge slide 15 is fixedly connected to the bottom surface of the partition plate 2 near the motor 9 and sleeved on the outside of the slot 14; a discharge port is fixedly connected to the end of the discharge slide 15 away from the motor 9, and the discharge port penetrates the side wall of the flow stabilizer box 1.

[0047] In practice, the slot 14 is opened at one end of the partition 2 near the inspection port 13, that is, at the end of the support rod 5 and the crossbar 6; the discharge port of the discharge slide 15 penetrates the side wall of the flow stabilizer box 1, and the discharge port of the discharge slide 15 is bolted with a sealing baffle.

[0048] When the crossbar 6 pushes the coal block to one end of the top surface of the partition 2, it pushes the coal block to the slot 14. The coal block falls into the discharge chute 15 through the slot 14. At this time, the staff only needs to open the discharge port of the discharge chute 15 to remove the coal block inside the discharge chute 15, which makes it easier for the staff to clean the filtered coal block.

[0049] like Figures 2 to 4 As shown, a spiral blade 16 is rotatably mounted inside the discharge chute 15; the rotating shaft of the spiral blade 16 is fixedly connected to the output shaft of the motor 9.

[0050] In specific implementation, the rotating shaft of the spiral blade 16 is installed into the discharge slide 15 by means of inserts. The rotating shaft of the spiral blade 16 near the motor 9 rotates through the side wall of the flow stabilizer box 1. The installation position of the motor 9 corresponds to the position of the spiral blade 16. The output shaft of the motor 9 is connected to the rotating shaft of the spiral blade 16 by means of a coupling.

[0051] Motor 9 drives transmission chain 4 to rotate, which in turn moves support rod 5 and crossbar 6, pushing coal blocks into discharge chute 15. At the same time, motor 9 also drives spiral blade 16 to rotate, working in conjunction with discharge chute 15 to push coal blocks out of discharge port of discharge chute 15, thereby further improving the convenience of cleaning for staff and improving cleaning efficiency.

[0052] like Figure 2 , Figures 4 to 6 As shown, annular guide rails 17 are fixedly connected to both sides of the inner cavity of the flow stabilizer box 1 and below the transmission chain 4; a slide rod 18 is slidably installed inside the support rod 5; a limiting rod 19 that slides with the annular guide rail 17 is fixedly connected to the side of the slide rod 18; and the end of the crossbar 6 is bolted to the bottom of the slide rod 18.

[0053] In specific implementation, the length of the annular guide rail 17 is the same as the length of the transmission chain 4, and the width of the annular guide rail 17 is greater than the width of the transmission chain 4; a groove is provided on the side of the annular guide rail 17 near the support rod 5, and the end of the limiting rod 19 is slidably connected to the groove of the annular guide rail 17; a sliding hole is provided on the support rod 5 from bottom to top, and a sliding rod 18 is slidably installed in the sliding hole, and a spring is provided on the top of the sliding rod 18; sliding grooves are provided on both sides of the sliding rod 18; the limiting rod 19 slides through the sliding grooves on both sides of the sliding rod 18;

[0054] The transmission chain 4 drives the support rod 5 to move. When the support rod 5 moves towards the upper part of the transmission chain 4, the support rod 5 drives the slide rod 18 to move. Since the limiting rod 19 moves along the annular guide rail 17, the limiting rod 19 is located in the upper part of the annular guide rail 17. And since the width of the annular guide rail 17 is greater than the width of the transmission chain 4, the slide rod 18 slides towards the inside of the support rod 5, further raising the crossbar 6.

[0055] When the support rod 5 moves toward the lower half of the transmission chain 4, the support rod 5 drives the slide rod 18 to move. Since the limiting rod 19 moves along the annular guide rail 17, the limiting rod 19 is located in the lower half of the annular guide rail 17. And since the width of the annular guide rail 17 is greater than the width of the transmission chain 4, the slide rod 18 slides toward the outside of the support rod 5, pressing the crossbar 6 further down.

[0056] By cooperating with the annular guide rail 17 and the limiting rod 19, not only are the support rod 5 and the slide rod 18 restricted to always remain in a vertically downward state, but the range of the rise and fall of the crossbar 6 is also effectively improved, thereby improving the cleaning effect on the top surface of the partition 2 and the filter element 3.

[0057] like Figures 5 to 6 As shown, the transmission chain 4 is hinged to a connector 20 on the side of the inner cavity of the flow stabilizer box 1; the top of the support rod 5 is hinged to the bottom of the connector 20.

[0058] In specific implementation, the connector 20 has an H-shaped structure, and through holes are provided at the top and bottom. The through hole at the top is connected to the transmission chain 4 through a hinge shaft. The top of the support rod 5 is located on the inner side of the bottom of the connector 20 and is connected by a hinge shaft.

[0059] The support rod 5 is connected to the transmission chain 4 by the connecting piece 20, so that the support rod 5 and the transmission chain 4 can rotate, thereby keeping the support rod 5 in a vertical state.

[0060] like Figures 5 to 6 As shown, a scraper 21 that can contact the top surface of the filter element 3 is bolted to the outer side of the crossbar 6;

[0061] In practice, the scraper 21 has an L-shaped cross-section, the inside of the scraper 21 is made of stainless steel, and a rubber pad is fixed to the outside. The scraper 21 is fixed to the side of the crossbar 6, and the bottom surface of the scraper 21 slides in contact with the top surface of the filter element 3, thereby improving the cleaning effect on the filter element 3.

[0062] like Figure 3 , Figure 7 , Figure 8 and Figure 10 As shown, multiple sets of countersunk holes are evenly opened on the outer periphery of the partition plate 2; the bottom surface of the outer periphery of the partition plate 2 is bolted to the inner wall of the flow stabilizer box 1 by multiple angle irons 22.

[0063] In practice, multiple angle irons 22 are installed at the same height on the inner wall of the flow stabilizer box 1 using bolts. The partition plate 2 is placed on the angle irons 22, and the bolt holes on the angle irons 22 are aligned with the countersunk holes on the partition plate 2. The bolts are then used to lock the plate.

[0064] The baffle 2 is fixedly installed inside the flow stabilizing box 1 by the angle iron 22. The support of the angle iron 22 effectively improves the support capacity of the baffle 2, thereby preventing it from falling off due to the impact of the medium and improving the safety of personnel entering.

[0065] like Figure 10 As shown, a top cap 23 is inserted into the top of the countersunk hole on the outer periphery of the partition 2;

[0066] In practice, after the partition 2 is installed on the angle iron 22, the countersunk hole on the partition 2 can be blocked by coal blocks, which not only makes cleaning difficult, but also makes subsequent disassembly difficult.

[0067] Therefore, by inserting a top cap 23 into the top of the countersunk hole, the top of the countersunk hole is covered and sealed, thereby preventing coal from entering. This not only facilitates the cleaning of coal but also the subsequent disassembly work.

[0068] Working principle: When the flow stabilizer box 1 is running normally, the support rods 5 and crossbars 6 on both sides are located at one end inside the flow stabilizer box 1. This is the initial position. Since the support rod 5 is located at the upper half of the transmission chain 4, the support rod 5 drives the slide rod 18 to move. Since the limiting rod 19 moves along the annular guide rail 17, the limiting rod 19 is located in the upper half of the annular guide rail 17. And since the width of the annular guide rail 17 is greater than the width of the transmission chain 4, the slide rod 18 slides towards the inside of the support rod 5, causing the scraper 21 to detach from the top surface of the partition 2.

[0069] When a certain amount of coal lumps accumulate on the top surface of the partition 2 and filter element 3, and cleaning is required, the control motor 9 starts, driving the rotating rod 8 to rotate via belt drive. This belt drive then causes the rotating rods 8 on both sides to rotate synchronously, driving the sprocket 7 to rotate, which in turn drives the transmission chains 4 on both sides to rotate synchronously. When the transmission chain 4 drives the support rod 5 past the sprocket 7, the top of the support rod 5 moves to the lower half of the transmission chain 4. The support rod 5 then drives the sliding rod 18 to move. Because the limiting rod 19 moves along the annular guide rail 17, it is positioned in the lower half of the annular guide rail 17. Furthermore, because the width of the annular guide rail 17 is greater than the width of the transmission chain 4, the sliding rod 18... 8 slides outwards towards the support rod 5, causing the height of the support rod 5 and the crossbar 6 to decrease, so that the scraper 21 contacts the top of the filter element 3. The drive chain 4 continues to move the support rod 5 and the crossbar 6 towards the other end of the flow stabilizing box 1. The scraper 21 pushes the coal block towards the end of the flow stabilizing box 1, that is, the top end of the partition 2. When the drive chain 4 moves the support rod 5 and the crossbar 6 to another sprocket 7, which is the end position, the drive chain 4 carries the top of the support rod 5 around the sprocket 7, so that the top of the support rod 5 moves to the upper half of the drive chain 4, so that the scraper 21 moves upwards away from the top surface of the partition 2. The drive chain 4 drives the support rod 5 and the crossbar 6 back to the initial position.

[0070] The scraper 21 pushes the coal block to the slot 14, and the coal block falls into the discharge chute 15 through the slot 14. At the same time, the motor 9 drives the spiral blade 16 to rotate, which, together with the discharge chute 15, pushes the coal block out of the discharge port of the discharge chute 15. This makes it easier for the staff to clean up, and the staff do not need to enter the inside of the flow stabilizer 1. Not only is the cleaning operation convenient, but it also avoids the staff from inhaling harmful gases.

[0071] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
