Description

Technical Field

[0001] This invention relates to the field of coal gasification ash and slag separation technology, and in particular to a deep separation and treatment device for coal gasification ash and slag. Background Technology

[0002] Coal gasification slag can be divided into two categories: coarse slag and fine slag. Fine slag usually has a higher carbon content, so after the fine slag is discharged, it needs to be subjected to carbon-ash separation to separate the carbon-rich concentrate particles.

[0003] Before using a froth flotation machine to float fine slag, the slag and water need to be mixed and stirred to obtain the required flotation slurry. To improve the flotation effect of the foam on particles, the slurry is usually prepared within a fixed ratio range. Since the total amount of fine slag varies each time, and the amount of slurry that the flotation machine can perform in a single batch is fixed, the fine slag needs to be processed in batches. However, it is difficult to achieve a precise feed of fine slag each time it is mixed with water, which may result in the slurry ratio exceeding or falling outside the fixed limit. Furthermore, after mixing the slurry in the mixing tank, a significant amount of adhering material will adhere to the inner wall of the tank, requiring manual cleaning later. During froth flotation, the slurry level inside the flotation cell needs to be monitored manually in real time. When the level is high, slurry may overflow and mix with the foam, further compromising the overall flotation effect. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a deep separation and treatment device for coal gasification ash residue.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention incorporates a temporary storage silo mechanism. Before flotation of coal gasification ash, a grinding mill grinds the ash, preventing clumping and ensuring the ash particles meet flotation standards. This also improves the mixing effect of the ash particles with water. The ground ash is quantitatively fed through a weighing hopper, temporary storage silo, and weighing mechanism, ensuring thorough mixing with a fixed amount of water. This guarantees the slurry remains within a fixed ratio, ensuring optimal flotation results. During mixing with water, a drive assembly and a stirring and cleaning mechanism ensure thorough mixing of water and ash. During flotation, a level trigger assembly, an emergency interception plate, and an overflow recovery tank handle slurry overflow, maintaining overall flotation efficiency. After flotation, the drive assembly and stirring and cleaning mechanism self-clean the slurry mixing tank, eliminating the need for manual cleaning and effectively improving overall ash separation.

[0022] This invention utilizes a temporary storage hopper mechanism. A conical funnel formed by six hopper combination plates enables temporary storage of ash and slag during feeding. The conical hopper can store a fixed amount of ash and slag. When the radio frequency admittance level gauge in the grinder senses that the amount of ash and slag in the conical hopper has reached the fixed level, the six baffle plates close. Simultaneously, the grinder continues grinding, and the six hopper combination plates open. After the ash and slag in the conical hopper have completely entered the weighing hopper, the six hopper combination plates close, the baffle plates open, and a second feeding operation is performed on the conical hopper. After two such operations, the amount of ash and slag in the weighing hopper is close to the limit. At this point, a small amount of ash and slag is added to the weighing hopper until the amount of ash and slag in the weighing hopper reaches the fixed level, thus achieving a quantitative feeding operation of ash and slag before mixing.

[0023] This invention features a weighing mechanism. The first gear rotates and meshes with the gear block to drive the movable frame, which in turn moves the lifting column downward. Simultaneously, the outer fixed plate and the weighing bucket descend. When the weighing bucket is completely placed on the weighing frame, the weighing sensor can weigh the weighing bucket and the ash inside it. At this time, the lifting column descends to a certain distance from the outer fixed plate to ensure that the weighing bucket can be weighed normally. The obtained weighing data reflects the difference between the existing amount of ash inside the weighing bucket and the set amount, allowing for a small amount of replenishment of the ash inside the weighing bucket.

[0024] This invention features a driving stirring and cleaning mechanism. After the ash and slag enter the slurry mixing tank, the driving shaft drives the stirring blades to mix the ash and slag with water. After flotation is completed, the inner ring and the movable ring are locked together, and then the cleaning roller is rotated to clean the inside of the slurry mixing tank.

[0025] This invention features a drive trigger assembly. A third gear rotates and meshes with a second gear. A squeezing ball presses the trigger switch two, activating it. The system performs two rounds of feeding into a conical hopper and transfers a fixed amount of ash and slag to a weighing hopper for quantitative feeding. During this feeding process, the third and second gears rotate normally and mesh. When the ash and slag in the weighing hopper reach a near-limit value, the baffle plate is kept closed. During this process, a small amount of ash and slag is added to the weighing hopper through the hopper assembly plate. Once the limit is reached, the third gear unlocks from the connecting column, allowing the connecting column to idle. The squeezing ball no longer triggers the trigger switch two, the baffle plate closes, and after mixing, the meshing of the third and second gears drives the stirring blades to mix the ash, slag, and water. After overall flotation, the meshing of the third and second gears drives the cleaning roller to automatically clean the inside of the slurry mixing hopper. This achieves coordinated feeding of ground ash and slag, weighing after feeding, mixing after weighing, and automatic cleaning after separation.

[0026] This invention incorporates a liquid level triggering component. A trigger switch is positioned inside the froth flotation machine at a high liquid level warning point. When the level exceeds this warning line, the slurry inside the froth flotation machine may overflow into the froth collection tank. As the slurry level inside the froth flotation machine rises, the float rises synchronously. When the float rises to the point where it presses against the trigger switch, the trigger switch is activated. At this time, the system issues a warning, the scraper stops rotating, and the emergency interception plate rotates upwards to an inclined position to intercept the slurry. The overflow recovery tank can intercept and recover some of the leaked slurry. The recovered slurry is then pumped back into the froth flotation machine for further flotation, preventing the slurry from overflowing into the froth collection tank and mixing with the froth, thus affecting the concentrate separation effect.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Reference Figure 1-13A deep separation and treatment device for coal gasification ash residue includes a frame 1. A slurry mixing tank 2 is fixedly installed on the frame 1. The slurry mixing tank 2 is used to stir and mix coal gasification ash residue with water to obtain a mixed slurry. A weighing tank 3 is movably installed on the upper side of the frame 1. The weighing tank 3 is used to transition the ash residue before mixing it with water. A valve is provided at the bottom discharge port of the weighing tank 3. A grinder 4 is fixedly installed on the upper side of the weighing tank 3. The grinder 4 is used to grind the ash residue before it is fed into the machine to ensure that the ash residue particles meet the flotation particle size standard. A foam flotation machine 5 is provided on one side of the frame 1. The foam flotation machine 5 can perform foam flotation on the slurry after mixing the ash residue with water to separate carbon-rich particles from the fine coal gasification residue. A weighing mechanism 7 is installed between the frame 1 and the weighing tank 3. The weighing mechanism 7 is used to weigh the ash and slag, ensuring that a quantitative amount of ash and slag enters the slurry mixing tank 2 and mixes with water. This ensures the slurry remains within a fixed ratio range, guaranteeing the normal flotation operation of the froth flotation machine 5. The slurry mixing tank 2 is equipped with a driven stirring and cleaning mechanism 8. This mechanism stirs and mixes the ash and slag and water entering the slurry mixing tank 2. The driven stirring and cleaning mechanism 8 is driven by a drive trigger component, which works in conjunction with the driven stirring and cleaning mechanism 8 to achieve mixing and stirring of the ash and slag and water inside the slurry mixing tank 2, as well as subsequent cleaning operations, and to remove any adhering substances from the inner wall of the slurry mixing tank 2. A temporary storage hopper mechanism 6 is provided between the weighing tank 3 and the grinding mill 4. The temporary storage hopper mechanism 6 can work with the weighing mechanism 7 and the drive trigger component to realize the quantitative feeding operation of ash and slag, ensuring that the amount of ash and slag entering the slurry mixing tank 2 each time is about a fixed value, so as to ensure that the slurry obtained by mixing ash and slag with water is within a fixed ratio range. A scraper 51 is rotatably installed on the froth flotation machine 5. The scraper 51 is used to scrape off the foam floating on the surface of the slurry during flotation. A foam collection box 55 is provided on one side of the froth flotation machine 5 for collecting foam. The foam collection box 55 is connected to the external conveying equipment. After the foam is scraped off, it is conveyed by the conveying equipment for the next solid-liquid separation and evaporation drying operation. A pre-sedimentation tank 54 is provided on one side of the froth flotation machine 5. The pre-sedimentation tank 54 performs pre-sedimentation on the tailings discharged from the froth flotation machine 5. The pre-sedimentation tank 54 is connected to the top sand discharge port of the froth flotation cell of the froth flotation machine 5 via a slurry pump. An overflow recovery tank 56 is installed between the froth flotation machine 5 and the froth collection tank 55. The overflow recovery tank 56 intercepts and recovers the overflow slurry. The overflow recovery tank 56 is connected to the froth flotation machine 5 via a slurry pump. The overflow slurry recovered in the overflow recovery tank 56 is pumped back into the froth flotation machine 5 for froth flotation. An emergency interception plate 53 is rotatably installed at the froth scraping position of the froth flotation machine 5. The emergency interception plate 53 is driven by a servo motor. When the slurry level in the froth flotation machine 5 exceeds the warning value, the scraper 51 stops rotating synchronously.The emergency interception plate 53 rotates to an upward tilt to intercept overflowing slurry. Part of the overflowing slurry can enter the overflow recovery tank 56 for recovery. The froth flotation machine 5 is equipped with a level triggering component, which works in conjunction with the emergency interception plate 53 to perform emergency operation when the slurry level is higher than the warning level. A temporary storage silo mechanism 6 is provided, and before flotation of the gasification ash, the grinding mill 4 grinds the ash to prevent clumping and ensure that the ground ash particles meet flotation standards. This also improves the mixing effect of the ash particles with water. The ground ash can be passed through the weighing tank 3, the temporary storage silo mechanism 6, and the weighing mechanism 7. The system coordinates with water to achieve quantitative feeding, ensuring that the ash and slag are quantitatively fed and thoroughly mixed with a fixed amount of water. This guarantees that the mixed slurry is within a fixed ratio range, thus ensuring the subsequent flotation effect. During mixing with water, the drive assembly, in conjunction with the driving stirring and cleaning mechanism 8, ensures thorough mixing of water and ash and slag. Simultaneously, during slurry flotation, the level trigger assembly, in conjunction with the emergency interception plate 53 and overflow recovery tank 56, handles slurry overflow emergencies, ensuring the overall flotation effect. Furthermore, after flotation separation, the drive assembly, in conjunction with the driving stirring and cleaning mechanism 8, cleans the inside of the slurry mixing tank 2, eliminating the need for separate manual cleaning later, effectively improving the overall ash and slag separation effect.

[0043] As an optimized technical solution for a deep separation and treatment device for coal gasification ash and slag according to the present invention, the temporary storage hopper mechanism 6 includes an installation ring 61, a connecting plate 62, a baffle plate 63, a connecting ring 64, an external connecting plate 65, a hopper combination plate 66, and an extension plate 67. The installation ring 61 is fixedly installed at the bottom of the grinder 4 and has a circular ring structure. The connecting ring 64 is fixedly installed on the upper side of the weighing barrel 3 through an external connecting frame. Six baffle plates 63 are slidably installed at the bottom of the installation ring 61. The baffle plates 63 are arc-shaped plates with a central angle of 60°. The connecting plate 62 is fixedly installed at the top of the baffle plates 63 and is driven by a hydraulic telescopic rod. The hydraulic telescopic rod is electrically connected to an external controller. The six hopper combination plates 66 are movably installed at the bottom of the baffle plates 63. The six hopper combination plates 66 can be combined to form a conical hopper. When the six hopper combination plates 66 are opened, a leakage port can be formed between them, and the ash and slag can be discharged into the slurry through the leakage port. Inside the mixing tank 2, when the hopper combination plate 66 is opened twice, the ash and slag in the weighing tank 3 can approach the limit amount. The extension plate 67 is fixedly installed on the outer wall of the hopper combination plate 66 near the upper end. The extension plate 67 is driven by a hydraulic telescopic rod, which is electrically connected to an external controller. The external plate 65 is fixedly installed on the outer wall of the hopper combination plate 66 near the lower end. The external plate 65 is driven by a hydraulic telescopic rod, which is electrically connected to an external controller. The hydraulic telescopic rod used to drive the extension plate 67 and the external plate 65 is fixedly installed on the connecting ring 64. The upper and lower feed ports of the grinding machine 4 are equipped with radio frequency admittance level gauges (TXSR) that work with the hopper combination plate 66. The hopper combination plate 66 can temporarily store the ash and slag. The ash and slag enter the conical hopper formed by the six hopper combination plates 66 through the grinding machine 4 for temporary storage. When the radio frequency admittance level gauge senses that the ash and slag in the conical hopper is full, the baffle plate 63 closes, stopping the feeding into the conical hopper.With the above structure, the conical funnel formed by the six hopper combination plates 66 enables temporary storage of ash and slag during feeding. The fine slag from coal gasification is fed into the grinder 4 for grinding. The ground slag then enters the conical hopper formed by the hopper combination plates 66 for temporary storage. The conical hopper can store a fixed amount of ash and slag. When the radio frequency admittance level gauge in the grinder 4 senses that the amount of ash and slag in the conical hopper has reached a fixed level, the six baffle plates 63 close. Simultaneously, the grinder 4 continues grinding, and synchronously, the six hopper combination plates 66 open, forming a discharge port between them. The ash and slag can slowly flow into the weighing bucket 3 through the discharge port. When the conical hopper... After the ash and slag in the hopper have completely entered the slurry mixing tank 2, the six hopper combination plates 66 close, and the baffle plate 63 opens, performing a second feeding operation on the conical hopper. After two such operations, the ash and slag inside the weighing tank 3 is close to the predetermined amount. At this point, a small amount of ash and slag is added to the weighing tank 3. During this small-scale replenishment, the connecting plate 62 remains closed. Simultaneously, the grinder 4 stops grinding, and the three hopper combination plates 66 open, adding a small amount of ash and slag to the weighing tank 3 through the conical hopper. When the ash and slag inside the weighing tank 3 reaches a fixed amount, the hopper combination plates 66 close, thus achieving a quantitative feeding operation of the ash and slag before mixing.

[0044] As an optimized technical solution for a deep separation and treatment device for coal gasification ash residue according to the present invention, the weighing mechanism 7 includes a support frame 71, a movable frame 72, a first gear 73, a lifting seat 74, a lifting column 75, an outer fixed plate 76, a weighing frame 77, and a weighing sensor 78. Two support frames 71 are symmetrically fixedly installed on both sides of the top of the frame 1. The movable frame 72 is slidably installed on the support frame 71. Tooth blocks 721 are uniformly fixedly installed on one side of the inner wall of the movable frame 72. The tooth blocks 721 are trapezoidal blocks. The first gear 73, which meshes with the movable frame 72, is rotatably installed on the support frame 71. The first gear 73 is driven by a servo motor, which is electrically connected to an external controller. The outer fixed plate 76, used to connect the weighing barrel 3, is slidably installed inside the support frame 71. The lifting seat 74 is fixedly installed on the movable frame 72. The lifting column 75, used to drive the outer fixed plate 76 to lift the weighing barrel 3, is fixedly installed on the lifting seat 74. At the top, two weighing frames 77 are fixedly installed on both sides of the top of the frame 1. The two weighing frames 77 can support the weighing barrel 3. The weighing sensor 78 is fixedly installed on the weighing frame 77 and is electrically connected to the external controller. The weighing sensor 78 can perform weighing operation on the weighing barrel 3. With the above structure, the first gear 73 rotates and drives the movable frame 72 to move the lifting column 75 downward through meshing with the tooth block 721. The outer fixed plate 76 and the weighing barrel 3 descend synchronously. When the weighing barrel 3 is completely placed on the weighing frame 77, the weighing sensor 78 can perform weighing operation on the weighing barrel 3 and the ash inside it. At this time, the lifting column 75 descends to a certain distance from the outer fixed plate 76 to ensure that the weighing barrel 3 can be weighed normally. The weighing data reflects the difference between the existing amount of ash inside the weighing barrel 3 and the set amount, so that a small amount of ash inside the weighing barrel 3 can be replenished.

[0045] As a technical optimization scheme for a deep separation and treatment device for coal gasification ash and slag according to the present invention, the driving stirring and cleaning mechanism 8 includes a drive shaft 81, cleaning rollers 82, a movable ring 83, stirring blades 84, and an inner connecting ring 85.

The stirring blades 84, used for stirring and mixing, are uniformly fixed on the drive shaft 81. The rotation of the stirring blades 84 can stir and mix the ash, slag, and water. Two cleaning rollers 82 are rotatably installed inside the slurry mixing tank 2. The cleaning rollers 82 can clean the inner wall of the slurry mixing tank 2. The cleaning operation is performed by rotating a movable ring 83, which connects the two cleaning rollers 82, inside the slurry mixing tank 2. An inner ring 85, which connects the drive shaft 81, is also rotated on the slurry mixing tank 2. The inner ring 85 and the movable ring 83 are connected to each other via a connecting assembly. With this structure, after the ash and slag enter the slurry mixing tank 2, the drive shaft 81 can drive the stirring blades 84 to mix the ash and slag with water. Simultaneously, after flotation, the inner ring 85 and the movable ring 83 can be locked together before rotating to drive the cleaning rollers 82 to clean the inside of the slurry mixing tank 2.

[0046] As an optimized technical solution for a deep separation and treatment device for coal gasification ash and slag according to the present invention, the connecting assembly includes a locking block 87, a first laser emitter 871, a locking frame 88, and a first laser receiver 881. The locking block 87 is fixedly installed at the bottom of the inner ring 85, and a groove is provided at the bottom of the locking block 87. The first laser emitter 871 (QEB373GR) is fixedly installed inside the groove and is electrically connected to an external controller. The locking frame 88 is fixedly installed at the top of the movable ring 83 and can be connected to the locking block 87. The first laser receiver 881 (CHQ-IRPT), which is used in conjunction with the first laser transmitter 871, is fixedly installed inside the mounting frame 88. The first laser receiver 881 is electrically connected to the peripheral controller. With the above structure, the first laser transmitter 871 and the first laser receiver 881 cooperate with each other to achieve the alignment of the locking block 87 and the mounting frame 88 during the rotation of the inner ring 85. After alignment, the locking block 87 and the mounting frame 88 can cooperate to achieve the locking operation between the inner ring 85 and the movable ring 83.

[0047] As an optimized technical solution for a deep separation and treatment device for coal gasification ash residue according to the present invention, the drive triggering component includes a second gear 86, a compression ball 861, a spring 862, a third gear 89, a trigger switch 891, and a connecting column 892. The second gear 86 is fixedly installed on the inner ring 85, and the third gear 89, which meshes with the second gear 86, is rotatably installed on the frame 1. The connecting column 892, which connects to the third gear 89, is rotatably installed on the frame 1. The connecting column 892 is rotatably connected to the third gear 89, and the third gear 89 and the connecting column 892 are interconnected through an alignment component. The compression ball 861 moves evenly and securely. Between every two adjacent teeth of the second gear 86, the extrusion ball 861 has a spherical structure. The second gear 86 has a slot for mounting the extrusion ball 861, and a spring 862 is fixedly installed inside the slot. One end of the spring 862 is fixedly connected to the extrusion ball 861. Trigger switches 891 are evenly fixedly installed between every two adjacent teeth of the third gear 89. When the second gear 86 and the third gear 89 mesh, they can drive the extrusion ball 861 to contact the trigger switch 891, at which time the trigger switch 891 remains in the triggered state. With the above structure, ash and slag enter the interior of the grinding mill 4. During grinding, the third gear 89 rotates and meshes with the second gear 86. The extrusion ball 861 extrudes the trigger switch 891, activating it. A fixed amount of ash and slag is then quantitatively fed into the weighing hopper 3 via two feeding cycles and transfer. During this quantitative feeding process, the third gear 89 and the second gear 86 are in normal rotating meshing. When the ash and slag in the weighing hopper 3 reaches a near-limit value after weighing, the baffle plate 63 is kept closed. During this process, a small amount of ash and slag is added to the weighing hopper 3 through the opening of the hopper assembly plate 66 until the limit is reached. After measurement, the connecting column 892 is unlocked by the third gear 89, allowing the connecting column 892 to idle. The extrusion ball 861 no longer triggers the second trigger switch 891, and the baffle plate 63 is closed. After mixing, the third gear 89 meshes with the second gear 86 to drive the stirring blade 84 to mix and stir the ash and water. After the overall flotation is completed, the third gear 89 meshes with the second gear 86 to drive the cleaning roller 82 to automatically clean the inside of the slurry mixing tank 2. This achieves the coordination between the quantitative feeding of ash after grinding, the weighing operation after feeding, the mixing and stirring after the weighing is qualified, and the automatic cleaning after separation.

[0048] As an optimized technical solution for a deep separation and treatment device for coal gasification ash and slag according to the present invention, the alignment component includes a positioning block 893, a second laser emitter 894, and a second laser receiver 895. The positioning block 893 is movably mounted on the connecting column 892 and is driven by a pneumatic telescopic rod. The second laser emitter 894 (QEB373GR) is fixedly mounted on the positioning block 893 and is electrically connected to an external controller. A limiting port for connecting the positioning block 893 is provided on the third gear 89. The second laser receiver 895 is fixedly mounted inside the limiting port and is electrically connected to the external controller. With the above structure, the second laser emitter 894 and the second laser receiver 895 (CHQ-IRPT) cooperate to identify the alignment of the moving ring 83 and the limiting port, thereby realizing the locking and unlocking operation of the connecting column 892 and the third gear 89.

[0049] As a technical optimization scheme for a deep separation and treatment device for coal gasification ash residue according to the present invention, the liquid level triggering component includes a warning liquid level box 52, a trigger switch 521, and a float 522. The warning liquid level box 52 is fixed inside the foam flotation machine 5 near the upper end. The warning liquid level box 52 has a hollow structure. The trigger switch 521 is fixedly installed inside the warning liquid level box 52 and is located at the corresponding slurry liquid level warning point of the foam flotation machine 5. The float 522 is movably installed inside the warning liquid level box 52. The float 522 has a spherical structure. When the float 522 floats upward, it can squeeze and trigger the trigger switch 521. By setting the above structure, the trigger switch 521 is located in the foam flotation machine 5. At the internal high liquid level warning point, if the level exceeds the warning line, the slurry inside the froth flotation machine 5 may overflow into the froth collection box 55. When the slurry level inside the froth flotation machine 5 rises, the float 522 rises synchronously. When the float 522 rises to the point where it presses against the trigger switch 521, the trigger switch 521 is triggered. At this time, the system issues a warning, the scraper 51 stops rotating, and the emergency interception plate 53 rotates upward to an inclined position to intercept the slurry. The overflow recovery box 56 can intercept and recover some of the leaked slurry. The recovered slurry is pumped into the froth flotation machine 5 for a second flotation operation to prevent the slurry from overflowing into the froth collection box 55 and mixing with the foam, thus affecting the concentrate separation effect.

[0050] In use, the coal gasification slag is transported to the grinding mill 4 by external conveying equipment in preparation for feeding.

[0051] The fine slag from coal gasification is fed into the grinding mill 4 for grinding to improve the mixing effect of fine slag particles and water in the later stage and ensure that the particle size of the fine slag meets the requirements of foam flotation. During grinding, the six baffle plates 63 are in the open state. The ground fine slag enters the conical hopper formed by the hopper combination plate 66 for temporary storage. The conical hopper can store a fixed amount of ash slag. When the radio frequency admittance level gauge in the grinding mill 4 senses that the amount of ash slag in the conical hopper has reached the fixed level, the six baffle plates 63 are closed. At the same time as the baffle plates 63 are closed, the grinding mill 4 continues to grind. Simultaneously, the six hopper combination plates 66 are opened, and a discharge port is formed between the hopper combination plates 66. The ash slag can be discharged into the slurry mixing tank 2 through the discharge port. When the ash slag in the conical hopper has completely entered the slurry mixing tank 2, the six hopper combination plates 66 are closed and the baffle plates 63 are opened to perform a second feeding operation on the conical hopper. This cycle is repeated. After two such operations, the ash slag in the weighing tank 3 is close to the limit.

[0052] The first gear 73 rotates and, through meshing with the gear block 721, drives the movable frame 72 to move the lifting column 75 downward. Simultaneously, the outer fixed plate 76 and the weighing bucket 3 descend. When the weighing bucket 3 is completely placed on the weighing frame 77, the weighing sensor 78 can weigh the weighing bucket 3 and the ash inside. At this time, the lifting column 75 descends to a certain distance from the outer fixed plate 76 to ensure that the weighing bucket 3 can be weighed normally. The weighing data reflects the difference between the existing ash content inside the weighing bucket 3 and the set amount. Subsequently, the three hopper combination plates 66 are opened, and the ash slowly leaks into the weighing bucket 3 through the gaps between the three hopper combination plates 66 to replenish the ash. When the amount of ash replenished into the weighing bucket 3 reaches the limit, the material is shut off. The bin assembly plate 66 and the first gear 73 rotate in the opposite direction to lift and reset the weighing barrel 3. After reset, the valves at the upper and lower feed ports of the weighing barrel 3 are opened, and a certain amount of ash and slag enters the slurry mixing barrel 2. At the same time, water is flushed into the slurry mixing barrel 2 to mix the ash and slag with water. While mixing, the drive shaft 81 rotates and drives the stirring blades 84 to fully mix the ash and slag and water. When the ash and slag inside the weighing barrel 3 begins to enter the slurry mixing barrel 2, the grinder 4 starts grinding the ash and slag simultaneously. After grinding, the above operation of storing the ground ash and slag in the conical hopper for temporary storage is repeated. After the ash and slag inside the weighing barrel 3 has completely entered the slurry mixing barrel 2, the ash and slag in the conical hopper repeats the above steps again to feed the ash and slag into the weighing barrel 3.

[0053] While the ash and slag are being fed into the grinding mill 4 for the first time, the third gear 89 rotates and meshes with the second gear 86. At this time, the extrusion ball 861 continuously extrudes against the trigger switch 891, which remains in the triggered state. The baffle plate 63 and the hopper assembly plate 66 are both in a normal opening and closing state. After the temporary storage hopper mechanism 6 has opened and closed twice to feed material into the weighing hopper 3, the weighing operation is performed on the weighing hopper 3. At this time, the amount of ash and slag inside the weighing hopper 3 is close to the limit value. A small amount of ash and slag is then added to the weighing hopper 3. The connecting plate 62 remains closed, and the grinder 4 stops grinding. At this time, the third gear 89 and the second gear 86 are always meshed and rotating. The three hopper combination plates 66 open and replenish a small amount of ash and slag into the weighing barrel 3 through the conical hopper. When the amount of ash and slag inside the weighing barrel 3 reaches the limit value, the third gear 89 unlocks from the connecting column 892. The locking and unlocking of the third gear 89 and the connecting column 892 is achieved by the second laser emitter 894 and the second laser receiver 895 cooperating during the rotation of the connecting column 892 to realize the positioning block 893 and the limit. After the position of the positioning port is aligned, the third gear 89 and the connecting column 892 are locked by the positioning block 893 engaging inside the limiting port. Unlocking is achieved by the positioning block 893 disengaging from the limiting port. After the third gear 89 and the connecting column 892 are unlocked, the connecting column 892 is in an idling state. At this time, the third gear 89 no longer meshes with the second gear 86, and the trigger switch 891 is no longer triggered. The system then receives a stop-feed command, the three hopper combination plates 66 close, and the first feeding into the weighing drum 3 ends. Subsequently, the valve at the discharge point of the weighing drum 3 opens, and the weighing... The ash and slag in the bucket 3 enter the slurry mixing bucket 2 and are fully mixed with water. At this time, the connecting column 892 locks with the third gear 89 again. The third gear 89 rotates and meshes with the second gear 86 to drive the stirring blade 84 to stir the ash and slag and water. While stirring, the weighing bucket 3, the grinding mill 4 and the conical bucket repeat the above quantitative feeding operation. After the stirring in the slurry mixing bucket 2 is completed, the slurry enters the foam flotation machine 5 for foam flotation. The ash and slag that has been weighed for the second time in the weighing bucket 3 enters the slurry mixing bucket 2 for the second slurry mixing and stirring operation.

[0054] After the ash and slag are thoroughly mixed with water in the slurry mixing tank 2, a slurry with a fixed ratio is obtained. The slurry, driven by a slurry pump, enters the froth flotation machine 5 for froth flotation. After entering the froth flotation machine 5, a capturing agent is injected. This agent can be diesel, kerosene, or a mixture of various non-polar hydrocarbon oils. After froth flotation in the froth flotation machine 5, the scraper 51 scrapes off the foam. A trigger switch 521 is set at the high liquid level warning point inside the froth flotation machine 5. When the level exceeds this warning line, the slurry inside the froth flotation machine 5 may overflow into the froth collection tank 55. When the slurry level inside the froth flotation machine 5 rises, the float 522 rises synchronously. When the float 522 rises to the point where it presses against the trigger switch 521, the trigger switch 521 is activated, the system issues a warning, and the scraper 51 stops rotating. Simultaneously, the emergency interception plate 53 rotates upward to an inclined position to intercept the slurry. The overflow recovery box 56 can intercept and recover some of the leaked slurry. The recovered slurry is pumped into the froth flotation machine 5 for a second flotation operation. When the operator adjusts the slurry level inside the froth flotation machine 5 to the normal state, the emergency interception plate 53 rotates to reset, the scraper 51 resumes rotation, and the flotation operation continues. When the scraper 51 scrapes the foam, carbon-rich concentrate particles are attached to the foam. The foam with carbon-rich concentrate attached enters the foam collection box 55 for storage and is transported by the external conveying equipment to carry out solid-liquid separation and evaporation drying operations, finally obtaining carbon-rich concentrate. At the same time, the tailings in the froth flotation machine 5 are pumped out to the pre-sedimentation box 54 by the external slurry pump for pre-sedimentation operation. The tailings after sedimentation can be used as building filler, and the wastewater mixture is discharged.

[0055] After separation, the inner ring 85 and the movable ring 83 are locked. The locking of the inner ring 85 and the movable ring 83 is achieved by the locking block 87 being inserted into the card frame 88. At the same time as the third gear 89 drives the second gear 86 to rotate synchronously, the first laser receiver 881 receives the laser emitted by the first laser emitter 871. The locking block 87 is aligned with the card frame 88. After alignment, the locking of the inner ring 85 and the movable ring 83 can be achieved by the locking block 87 being inserted into the card frame 88. Unlocking is achieved by the locking block 87 being removed from the card frame 88. After the inner ring 85 and the movable ring 83 are locked, water is poured into the slurry mixing tank 2. At this time, the inner ring 85 drives the movable ring 83 to rotate synchronously and drives the cleaning rod 82 to clean the slurry adhering to the inner wall of the slurry mixing tank 2.
