Description

Technical Field

[0001] This utility model relates to the field of coal slime filter press technology, and in particular to a rapid dewatering coal slime filter press. Background Technology

[0002] In the coal processing and washing process, the dewatering of coal slime is a crucial step. Traditional coal slime dewatering equipment often suffers from problems such as low dewatering efficiency, easy damage to filter cloth, and unstable dewatering effect. These problems seriously restrict the production efficiency and product quality of coal slime treatment.

[0003] Existing coal slime filter presses typically use two filter belts to drive the coal slime, which then enters between the belts for filtration. However, current filter presses generally use a fixed filter belt tension for dewatering, making it impossible to adjust the belt tension according to the different moisture contents of the coal slime. Coal slime with low moisture content is prone to excessive wear or even damage to the filter cloth when subjected to excessive pressure, while coal slime with high moisture content may not achieve sufficient dewatering due to insufficient pressure, resulting in poor filtration performance.

[0004] Therefore, it is necessary to design a coal slime filter press that can adjust the tension of the first and second filter belts according to different coal slime moisture contents, avoid excessive compression that could damage the filter cloth or impair the dewatering effect, improve the filtration effect, and enable flexible and rapid dewatering. Utility Model Content

[0005] To overcome the shortcomings of current filter presses that typically use a fixed filter belt tension for dewatering, making it impossible to adjust the filter belt tension according to different coal slime moisture contents, and causing excessive wear or even damage to the filter cloth when subjected to excessive pressure on coal slime with low moisture content, while coal slime with high moisture content may not achieve sufficient dewatering due to insufficient pressure, resulting in poor filtration effect, this utility model provides a coal slime filter press that can adjust the tension of the first and second filter belts according to different coal slime moisture contents, avoiding filter cloth damage or dewatering effect caused by excessive compression, improving filtration effect, and offering flexible and rapid dewatering.

[0006] Technical Solution: A rapid dewatering coal slime filter press includes a frame, a first motor, a first filter belt, a second motor, a second filter belt, an extrusion roller, auxiliary rollers, a third motor, a lead screw, and an adjusting roller. Two sets of auxiliary rollers are rotatably connected to the frame. The auxiliary rollers near the upper part of the frame consist of two rollers on the left and right, while those near the lower part of the frame consist of multiple rollers. The first motor is connected to the upper right front side of the frame, and its output shaft is connected to its adjacent auxiliary roller. The second motor is connected to the middle left front side of the frame, and its output shaft is connected to its adjacent auxiliary roller. The machine frame is connected to the following components: multiple extrusion rollers are rotatably connected to the right side of the frame; a third motor is connected to the front right side of the frame; a lead screw is connected to the output shaft of the third motor; the lead screw is rotatably connected to the frame; a moving block is threaded on the lead screw; a moving block is also slidably provided at the rear of the frame; and an adjusting roller is rotatably connected between the moving blocks. A first filter belt is wound between the second extrusion roller from left to right, the auxiliary roller in the same group near the upper part of the frame, and the adjusting roller; and a second filter belt is wound between the first and third extrusion rollers from left to right and the auxiliary roller in the same group near the lower part of the frame.

[0007] In addition, it is particularly preferred that the device also includes a collection chamber and a water outlet pipe, with the collection chamber connected to the lower part of the frame and the water outlet pipe connected to the left side of the collection chamber.

[0008] In addition, preferably, it also includes a baffle, an electric push rod and a guide block, with two electric push rods connected to the upper right of the frame, a baffle connecting the telescopic ends of the electric push rods, and multiple guide blocks connected to the upper left of the frame.

[0009] In addition, it is particularly preferred that the device also includes a high-pressure nozzle, with high-pressure nozzles connected to both the upper right and lower left parts of the frame, and the high-pressure nozzle on the upper right being located to the right of the electric push rod.

[0010] In addition, it is particularly preferred that a scraper is also included, with the scraper connected to the right middle part of the frame.

[0011] In addition, it is particularly preferred that the machine also includes a pulley and a hammer, with the hammer rotatably connected to the lower left of the frame, a pulley connected to the front of the hammer, and a pulley also connected to the front of the auxiliary roller adjacent to the hammer, with a flat belt wound between the pulleys.

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 protection scope of the present utility model.

[0021] A rapid dewatering coal slime filter press, such as Figures 1-5As shown, the assembly includes a frame 1, a first motor 2, a first filter belt 3, a second motor 4, a second filter belt 5, a squeezing roller 6, auxiliary rollers 7, a collection bin 8, a water outlet pipe 9, a baffle 10, an electric push rod 101, a guide block 11, a high-pressure nozzle 12, a third motor 13, a lead screw 14, an adjusting roller 141, a scraper 15, a pulley 16, and a hammer 17. Two sets of auxiliary rollers 7 are rotatably connected to the frame 1. The auxiliary rollers 7 near the upper part of the frame 1 consist of two parts, left and right, while the auxiliary rollers near the lower part of the frame 1... The machine consists of three parts: a first motor 2 is connected to the upper right front side of the frame 1, and the output shaft of the first motor 2 is connected to its adjacent auxiliary roller 7; a second motor 4 is connected to the middle left front side of the frame 1, and the output shaft of the second motor 4 is connected to its adjacent auxiliary roller 7; three extrusion rollers 6 are rotatably connected to the right side of the frame 1; a third motor 13 is connected to the front right side of the frame 1, and a lead screw 14 is connected to the output shaft of the third motor 13. The lead screw 14 is rotatably connected to the frame 1, and a moving block is threaded on the lead screw 14. The rear also has sliding blocks, and adjusting rollers 141 are rotatably connected between the moving blocks. A first filter belt 3 is wound between the second extrusion roller 6 (from left to right), the auxiliary roller 7 (near the upper part of the frame 1), and the adjusting roller 141. A second filter belt 5 is wound between the first and third extrusion rollers 6 (from left to right) and the auxiliary roller 7 (near the lower part of the frame 1). A collection chamber 8 is connected to the lower part of the frame 1, and a water outlet pipe 9 is connected to the left side of the collection chamber 8. Two electric push rods 101 are connected to the upper right part of the frame 1. A baffle 10 is connected between the telescopic ends of the electric push rod 101. Three guide blocks 11 are connected to the upper left of the frame 1. High-pressure nozzles 12 are connected to both the upper right and lower left of the frame 1. The high-pressure nozzle 12 on the upper right is located to the right of the electric push rod 101. A scraper 15 is connected to the middle right of the frame 1. A hammer 17 is rotatably connected to the lower left of the frame 1. A pulley 16 is connected to the front of the hammer 17. A pulley 16 is also connected to the front of the auxiliary roller 7 adjacent to the hammer 17. A flat belt is wound between the pulleys 16.

[0022] When using this device, first place the frame 1 in the area of ​​the rapid dewatering coal slime filter press, then start the electric push rod 101 to move the baffle 10 downwards, adjust the height distance between the baffle 10 and the first filter belt 3, then start the first motor 2 and the second motor 4 to drive the auxiliary roller 7 to rotate, causing the extrusion roller 6, the adjusting roller 141, the first filter belt 3 and the second filter belt 5 to rotate, conveying the coal slime to the left through the first filter belt 3. The guide block 11 diverts and guides the coal slime to prevent it from accumulating. Subsequently, the coal slime is conveyed through the conveyor... As the coal slurry enters between the first filter belt 3 and the second filter belt 5, it approaches the regulating drum 141 and the extrusion drum 6. The first filter belt 3 and the second filter belt 5 then press and filter the coal slurry, causing the squeezed water to be discharged into the collection chamber 8 and out through the outlet pipe 9. The filtered coal slurry is then conveyed to the right through the first filter belt 3 and the second filter belt 5, and scraped off by the scraper 15. After the equipment is used, a water supply pipe is connected to the high-pressure nozzle 12, allowing water to flow as the first filter belt 3 and the second filter belt 5 rotate. The spray is applied to the surfaces of the first filter belt 3 and the second filter belt 5, facilitating easy cleaning of both without subsequent manual cleaning, saving manpower and time. The auxiliary roller 7 rotates, driving the pulley 16 to rotate, which in turn drives the flat belt to rotate, causing the striking hammer 17 to contact the second filter belt 5 and strike it, thus removing the coal slime from the second filter belt 5. When it is necessary to filter coal slime with different moisture contents, the third motor 13 can be started to drive the lead screw. Rotating the 14th ring causes the moving block to move under the action of the screw thread, which in turn drives the adjusting roller 141 to move up and down. When the coal slime has a high moisture content, the tension of the first filter belt 3 and the second filter belt 5 is increased to improve the filtration effect. Conversely, the tension of the first filter belt 3 and the second filter belt 5 is appropriately loosened to avoid excessive compression that could damage the filter cloth or result in poor dewatering. This allows for adjustment of the tension of the first filter belt 3 and the second filter belt 5 according to different coal slime moisture contents, avoiding excessive compression that could damage the filter cloth or result in poor dewatering, thus improving the filtration effect and making it flexible to use.
