Inside the processing box 3, at the end of the guide plate 17, there is a rotatable mounting plate 24. The outer wall of the processing box 3 is connected to the mounting plate 24 at the corresponding position. One end of the synchronization component 19 is connected to the center of the mounting plate 24, and the other end of the synchronization component 19 is connected to the control component 16.

Inside the processing box 3, between the guide plate 17 and the second conveyor 8, there is an auxiliary component 20. The upper end face of the processing box 3 is fixedly connected to the side of the magnetic separator 1 and is connected to the water inlet pipe 5, which communicates with the inside of the processing box 3.

[0043] The second conveyor 8 includes a circulating conveyor filter 801, and a guide plate 804 is provided inside the conveyor filter 801. A guide chamber 12 is fixedly installed on the outer wall of the processing box 3 at the corresponding positions of the two ends of the guide plate 804.

[0044] The auxiliary component 20 includes a swing rod 2005 rotatably installed in the processing box 3. The two ends of the swing rod 2005 drive the end of the guide plate 17 and the corresponding position on the conveying filter screen 801 to move up and down respectively.

[0045] In use, the magnetic separator 1 can dry or wet select the magnetic material in the coal gasification ash, when the magnetic separator 1 wet selects the coal gasification ash, the control assembly 16 drives the end of the switching plate 25 to slide in the switching channel 15, under the action of the switching plate 25, the switching plate 25 can block the cavity corresponding to the spiral separator 2 in the two cavities separated by the switching plate 25 in the switching channel 15, at this time, the switching channel 15 can only make the adding box 14 and the inside of the processing box 3 communicate, under the action of the magnetic separator 1, the magnetic material in the coal gasification ash slurry is separated, the coal gasification ash slurry without magnetic material enters the inside of the processing box 3, when the switching plate 25 moves, under the driving action of the synchronous assembly 19, the mounting plate 24 rotatingly installed in the processing box 3 is adjusted, so that the two ends of the mounting plate 24 are respectively extruded with the end of the guide plate 17 and the end of the protrusion fixedly installed on the inner wall of the processing box 3, after the end of the mounting plate 24 with flexible structure such as rubber is extruded with the end of the guide plate 17 and the end of the protrusion fixedly installed on the inner wall of the processing box 3, a closed cavity composed of the guide plate 17 and the mounting plate 24 is formed in the inside of the processing box 3, so that the coal gasification ash slurry after wet selection by the magnetic separator 1 enters the closed cavity, then the user can open the blocking door 18 at the upper end of the adding box 14 to pour additives into the slurry in the closed cavity through the switching channel 15, and hot water or the like can be added to the slurry in the closed cavity through the adding box 14 to activate and pyrolyze the coal gasification ash, accelerate the reaction speed of the additives and the metal elements in the coal gasification ash, so that the metal elements contained in the coal gasification ash slurry form a precipitate and accumulate at the bottom of the closed cavity, and in the process of reaction between the additives and the metal elements in the slurry, the stirring assembly 22 can stir the slurry in the closed cavity, further accelerating the reaction speed of the additives and the metal elements in the slurry, after a period of reaction, the mounting plate 24 is driven to rotate by the synchronous assembly 19, so that the end of the mounting plate 24 and the end of the guide plate 17 open the open opening, so that the slurry in the closed cavity flows downward to contact the conveying filter screen 801, the porous structure of the conveying filter screen 801 can filter the coal gasification ash slurry with metal element precipitate, so that the solid precipitate with metal elements is left on the surface of the conveying filter screen 801 and transported to the outside of the processing box 3 under the continuous rotation of the conveying filter screen 801, the remaining slurry filtered by the conveying filter screen 801 is guided into the transition bin 11 through the guide bin 12 under the action of the guide plate 804, and then output to the outside of the device through the material guide pipe 9, when the coal gasification ash slurry flows from the inside of the closed cavity to the upper surface of the conveying filter screen 801, the swing rod 2005 swings synchronously, the two ends of the swing rod 2005 are respectively in contact with the end of the guide plate 17 and the conveying filter screen 801, and the end of the swing rod 2005 can make the end of the guide plate 17 and the conveying filter screen 801 vibrate up and down in the corresponding position,One end of the guide plate 17 is rotatably connected with the lower end of the inner wall of the treatment box 3 connected with the switching channel 15, and the inner wall of the treatment box 3 is fixedly installed with a support block below the connecting end of the guide plate 17, so that the guide plate 17 can only rotate upward with the active end as the axis, and the connecting part of the guide plate 17 and the inner wall of the treatment box 3 is provided with a waterproof rubber strip which can deform and is fixedly connected with the corresponding positions of the inner wall of the treatment box 3 and the guide plate 17 at both ends. Therefore, when the guide plate 17 and the corresponding position of the conveying filter screen 801 vibrate up and down, on one hand, the material on the guide plate 17 can fall faster, and on the other hand, the conveying filter screen 801 can assist and speed up the screening of the falling coal gasification slag slurry. When the magnetic separator 1 dry selects the coal gasification slag, the coal gasification slag dry material after being crushed by extrusion is screened by the magnetic separator 1 to remove the magnetic substances, and the remaining coal gasification slag dry material enters the inside of the treatment box 3. Before the magnetic separator 1 dry selects the coal gasification slag, the control assembly 16 drives the end of the switching channel 15 to slide in the switching channel 15 to block the cavity corresponding to the adding box 14, so that the spiral separator 2 arranged at the end of the switching channel 15 is in communication with the inside of the treatment box 3. Similarly, when the control assembly 16 adjusts the position of the switching plate 25, the mounting plate 24 in the treatment box 3 can be adjusted through the synchronous assembly 19. Under the action of the synchronous assembly 19, the mounting plate 24 is flipped to make the blowing assembly 21 arranged on the other side face the switching channel 15. The blowing assembly 21 can blow air to the falling slurry, and under the action of the wind force, the coal ash and light and small hollow glass beads in the coal gasification slag dry material can be blown into the inside of the switching channel 15. The coal ash and light and small hollow glass beads enter the inside of the spiral separator 2 for separation under the action of the wind force. The lighter dust is output through the upper end of the spiral separator 2, the hollow glass beads heavier than the dust are output from the lower end of the spiral separator 2, and the remaining coal gasification slag particles heavier than the dust and the hollow glass beads fall on the guide plate 17 arranged obliquely under the action of gravity. Under the guidance of the guide plate 17, the remaining coal gasification slag particles fall on the conveying filter screen 801 for screening and conveying. Under the action of the conveying filter screen 801, the remaining coal gasification slag particles can be screened again to separate the large particles and small particles in the remaining coal gasification slag particles. When the guide plate 17 guides the remaining coal gasification slag after removing the coal ash and the hollow glass beads and the conveying filter screen 801 screens it, the ends of the swing rod 2005 can also drive the end of the guide plate 17 and the corresponding position of the conveying filter screen 801 to vibrate, which also has the effect of accelerating the falling of the material on the guide plate 17 and accelerating the screening of the falling coal gasification slag particles by the conveying filter screen 801. The coal gasification slag large particles screened by the conveying filter screen 801 are transported to the outside of the treatment box 3 through the conveying filter screen 801.Small particles enter the transition bin 11 under the guidance of the guide plate 804; when the user uses the device to wetly select coal gasification ash and then needs to dryly select the coal gasification ash through the device, high-pressure water flow can be introduced into the inside of the treatment box 3 through the water inlet pipe 5, the corresponding valve inside the water inlet pipe 5 is opened, and the external water flow enters the sealed cavity inside the treatment box 3 through the water inlet pipe 5, so that the material attached to the guide plate 17 and the inner wall of the treatment box 3 can be cleaned, and the conveying filter screen 801 and the inner wall of the transition bin 11 can be cleaned synchronously in the process of water flow. After cleaning, the inside of the treatment box 3 can drive the air blowing assembly 21 to rotate through the mounting plate 24, so that the air blown out of the air blowing assembly 21 can dry the inside of the treatment box 3, and then the inside of the treatment box 3 after cleaning can be switched to dryly select the coal gasification ash, so that the mixing of different components in the coal gasification ash material can be avoided.

[0046] As a technical optimization scheme of the present application, the upper end of the spiral separator 2 is fixedly installed with a communication-provided ash outlet pipe 6, and the lower end of the spiral separator 2 is fixedly installed with a discharge pipe 7 which is in communication with the inside of the spiral separator 2. When the coal ash and light small hollow glass beads enter the inside of the spiral separator 2 under the action of the wind force, under the continuous action of the wind force, the coal ash with lighter quality moves upward at the middle position of the inside of the spiral separator 2 and is separated from the ash outlet pipe 6 to the outside of the spiral separator 2, and the hollow glass beads in the coal ash with lighter quality are spirally lowered in the inside of the spiral separator 2 and are output from the discharge pipe 7 to the outside of the spiral separator 2.

In use, the magnetic substances in the coal gasification ash separated by the magnetic separator 1 are conveyed to the first conveyor 4 and output outward, and the non-magnetic substances after the magnetic substances are screened out enter the inside of the treatment box 3 through the feed pipe 13 and are subjected to grading treatment.

[0048] As a technical optimization scheme of the present application, the control assembly 16 comprises a mounting frame 1604 fixedly installed on the upper end face of the switching channel 15 near one end of the treatment box 3, a threaded rod 1603 rotatably installed between the mounting frames 1604, one end of the threaded rod 1603 extending to outside the mounting frame 1604 through the mounting frame 1604, and a first gear 1602 fixedly installed at the end of the threaded rod 1603 outside the mounting frame 1604, the outer wall of the switching channel 15 being fixedly installed with the mounting frame 1604 at a position corresponding to the first gear 1602, a drive motor 1601 fixedly installed on the mounting frame 1604, the output end of the drive motor 1601 being fixedly connected with the end of the threaded rod 1603, the outer wall of the threaded rod 1603 being threadedly connected with a movable block 1605 inside the mounting frame 1604, and a through slot 1607 being provided through the upper end face of the switching channel 15 at a position corresponding to the movable block 1605, the lower end of the movable block 1605 being fixedly connected with the end of the switching plate 25 through the through slot 1607, wherein the other end of the switching plate 25 is movably connected with the inner wall of the switching channel 15, and the inside of the through slot 1607 is fixedly connected with an elastic strip 1606;

[0049] When the drive motor 1601 drives the threaded rod 1603 to rotate, the movable block 1605 can slide on the outer wall of the threaded rod 1603 under the threaded transmission of the threaded rod 1603 to the movable block 1605 and the limiting action of the through slot 1607 to the movable block 1605, and at the same time, the end of the switching plate 25 can slide in the inside of the switching channel 15 when the threaded rod 1603 slides, at this time, the other end of the switching plate 25 can slide in the inside of the switching channel 15 and also can rotate with the end edge of the switching plate 25 as the axis, a rectangular plate for separating the addition box 14 and the spiral separator 2 is fixedly installed at the other end in the inside of the switching channel 15, and a folding structure such as an organ plate is arranged between the end of the switching plate 25 close to the rectangular plate and the rectangular plate, so that the end of the switching plate 25 can ensure that the spaces on both sides of the switching plate 25 in the inside of the switching channel 15 are not connected with each other when the end of the switching plate 25 rotates and slides in the inside of the switching channel 15, and when the control assembly 16 moves to one side or the other side of the end of the switching channel 15, the switching plate 25 can block the two cavities corresponding to the addition box 14 and the spiral separator 2, respectively, so as to switch the device for wet coal gasification of ash or dry coal gasification of ash, and the elastic strip 1606 fixedly connected in the inside of the through slot 1607 is flexibly arranged and has strong deformation capacity, and the elastic strip 1606 can shield the open through slot 1607.

[0050] As a technical optimization scheme of the present application, the synchronous assembly 19 comprises a second gear 1901 fixedly connected with the center of the mounting plate 24, and the second gear 1901 is rotationally connected with the outer wall of the processing box 3. A transmission chain 1902 is arranged between the second gear 1901 and the first gear 1602, and the two ends of the transmission chain 1902 are respectively arranged in mesh with the second gear 1901 and the first gear 1602. When the driving motor 1601 drives the threaded rod 1603 to rotate in use, the first gear 1602 fixed at the end of the threaded rod 1603 rotates synchronously. Under the transmission action of the transmission chain 1902, the second gear 1901 can rotate synchronously. When the switching plate 25 moves in the switching channel 15 to block the cavity corresponding to the spiral separator 2 or the adding box 14 in the switching channel 15 to switch the dry selection and wet selection modes, the mounting plate 24 is driven to rotate and overturn by the second gear 1901, so that the blowing assembly 21 or the stirring assembly 22 arranged on both sides of the mounting plate 24 is correspondingly overturned to the direction opposite to the upper end surface of the guide plate 17. When the switching plate 25 blocks the cavity corresponding to the adding box 14, the blowing assembly 21 is synchronously driven to overturn and use upward. When the switching plate 25 blocks the cavity corresponding to the spiral separator 2, the stirring assembly 22 is synchronously driven to overturn and use upward. That is, under the action of the synchronous assembly 19, the first gear 1602 can drive the switching plate 25 and the mounting plate 24 to move simultaneously when rotating, so as to switch the wet selection or dry selection mode of the device for use, so that the operation process of the device in use is simpler.

[0051] As a technical optimization scheme of the present application, the blowing assembly 21 comprises a fan 2103 fixedly installed on the outer wall of the treatment box 3, a blowing pipe 2102 fixedly connected with the fan 2103 and arranged in communication with the inside of the fan 2103, and the end of the blowing pipe 2102 penetrates through the center of the second gear 1901 and the mounting plate 24 and is rotatably connected with the second gear 1901 and the mounting plate 24, and one side of the mounting plate 24 is fixedly provided with a blowing pipe 2101 arranged in communication with the inside of the blowing pipe 2102. In use, the wind power generated by the fan 2103 is input into the inside of the treatment box 3 through the blowing pipe 2102, and the blowing pipe 2102 is rotatably connected at the middle position of the mounting plate 24, so that when the mounting plate 24 rotates, it will not interfere with the blowing pipe 2102. When the device switches to the dry screening mode to screen the coal gasification ash, the wind power is blown out through the blowing pipe 2101, which can blow the coal ash and light and small hollow glass beads in the dry coal gasification ash into the inside of the switching channel 15, and under the action of the continuous wind power, the coal ash and hollow glass beads can be blown into the inside of the spiral separator 2 for separation. Part of the relatively heavy dry coal gasification ash particles falls on the inclined guide plate 17 under the action of gravity, and further screening is carried out on the conveying filter screen 801 under the guidance of the guide plate 17. When the inside of the treatment box 3 is cleaned by external water flow, the wind power blown out by the blowing pipe 2101 can accelerate the drying speed in the inside of the treatment box 3 by rotating the mounting plate 24.

That is, when the device switches to the dry separation mode to screen the coal gasification ash, the fan 2103 can be correspondingly started, when the device switches to the wet separation mode to screen the coal gasification ash, the plurality of motors in the stirring assembly 22 can be correspondingly started, and before the device switches from the wet separation mode to the dry separation mode, the device interior can be cleaned by water input through the water inlet pipe 5.

In use, the conveying filter screen 801 can be circularly driven by rotating the two groups of transmission rollers 803 driven by external forces. The conveying filter screen 801 has a porous structure. When the dry material and slurry of the coal gasification ash fall on the conveying filter screen 801, the porous structure can screen the dry material and slurry, thereby reclassifying the coal gasification ash material. The large-particle coal gasification ash material screened by the conveying filter screen 801 stays on the surface of the conveying filter screen 801 and is transported to the outside of the processing box 3 under the action of the two transmission rollers 803 for collection. The small-particle material on the conveying filter screen 801 enters the guide bin 12 with an arc-shaped cross section under the action of the arc-shaped guide plate 804, and then the small-particle material is guided into the transition bin 11 by the guide bin 12 and then output to the outside of the processing box 3 through the material guide pipe 9 for collection.

[0056] In use, when the transmission roller 803 in the second conveyor 8 rotates to drive the conveying filter screen 801 to convey the materials, the turbine 805 fixedly connected with the transmission roller 803 synchronously rotates, the turbine 805 is engaged with the worm 2002, so that the worm 2002 synchronously rotates, when the worm 2002 rotates, the two push-pull blocks 2003 slidingly installed on the reciprocating wire rods in the worm 2002 are away from each other at both ends of the rotating rod 2001, and then approach each other at the middle position of the worm 2002, in the process of continuous reciprocation of the two push-pull blocks 2003, the swing rod 2005 can be driven to swing through the two connecting rods 2004, when the swing rod 2005 swings, the upper end of the swing rod 2005 can lift the end of the guide plate 17 upward, the lifting rod 2007 fixedly installed at the lower end of the swing rod 2005 is arranged below the conveying filter screen 801, which can lift the conveying filter screen 801 upward, and the sleeve 2006 arranged on the outer wall of the lifting rod 2007 can be used to reduce the friction between the conveying filter screen 801 and the outer wall of the lifting rod 2007, so as to avoid the influence of the lifting rod 2007 on the normal activity of the conveying filter screen 801, in the process of continuous swinging of the swing rod 2005 repeatedly lifting the end of the guide plate 17 and lifting the corresponding position of the conveying filter screen 801, the falling of the materials on the guide plate 17 can be accelerated, and the screening speed of the materials on the conveying filter screen 801 can be also accelerated, when the device finishes the screening and conveying of the materials, the transmission roller 803 stops rotating, and the assembly synchronously stops moving.

[0057] In use, the magnetic separator 1 can dry or wet select the magnetic substances in the coal gasification ash:

[0058] When the magnetic separator 1 is used for wet separation of coal gasification ash, the threaded rod 1603 is driven to rotate by the driving motor 1601, and the movable block 1605 is driven to slide on the outer wall of the threaded rod 1603 under the thread transmission of the threaded rod 1603 to the movable block 1605 and the limiting action of the through slot 1607 to the movable block 1605. At the same time, the end of the switching plate 25 is driven to slide in the switching channel 15, and the cavity corresponding to the spiral separator 2 in the two cavities separated by the switching plate 25 in the switching channel 15 is blocked under the action of the switching plate 25. At this time, the switching channel 15 can only communicate the adding box 14 with the inside of the treatment box 3, and the magnetic material in the coal gasification ash slurry is separated under the action of the magnetic separator 1. The coal gasification ash slurry without magnetic material enters the inside of the treatment box 3. When the switching plate 25 moves, the first gear 1602 fixed to the end of the threaded rod 1603 is driven to rotate synchronously under the driving of the driving motor 1601 to drive the threaded rod 1603 to rotate, the second gear 1901 is driven to rotate synchronously under the transmission of the transmission chain 1902, and the second gear 1901 is driven to rotate synchronously under the transmission of the transmission chain 1902. When the switching plate 25 moves in the switching channel 15 to block the cavities corresponding to the spiral separator 2 or the adding box 14 in the switching channel 15 for switching the use modes of dry separation and wet separation, the mounting plate 24 is driven to rotate and overturn by the second gear 1901, so that the blowing assembly 21 or the stirring assembly 22 arranged on both sides of the mounting plate 24 is correspondingly overturned to the direction opposite to the upper end face of the guide plate 17. The mounting plate 24 installed in the treatment box 3 is adjusted, so that the two ends of the mounting plate 24 are respectively pressed against the ends of the protrusions fixedly installed on the guide plate 17 and the inner wall of the treatment box 3. After the ends of the mounting plate 24 with flexible structures such as rubber are pressed against the ends of the protrusions fixedly installed on the guide plate 17 and the inner wall of the treatment box 3, a closed cavity composed of the guide plate 17 and the mounting plate 24 is formed in the inside of the treatment box 3. Then the user can open the blocking door 18 at the upper end of the adding box 14 to pour the additives into the slurry in the closed cavity through the switching channel 15, and the additives can be added to the slurry in the closed cavity through the adding box 14 to activate and pyrolyze the coal gasification ash with hot water, so as to accelerate the reaction speed of the additives and the metal elements in the coal gasification ash, and then the metal elements contained in the coal gasification ash slurry form a precipitate and accumulate at the bottom of the closed cavity. In the process of the reaction between the additives and the metal elements in the slurry, the stirring assembly 22 can stir the slurry in the closed cavity to further accelerate the reaction between the additives and the metal elements in the slurry. After a period of reaction, the mounting plate 24 is driven to rotate by the synchronous assembly 19, so that the end of the mounting plate 24 is opened to the end of the guide plate 17, and the slurry in the closed cavity flows downward to contact the conveying filter screen 801.The porous arrangement of the conveying filter screen 801 can filter the coal gasification ash slurry with metal element precipitates, so that the solid precipitates with metal elements are left on the surface of the conveying filter screen 801 and transported to the outside of the processing box 3 under the continuous rotation of the conveying filter screen 801, and the remaining slurry filtered by the conveying filter screen 801 is guided into the transition bin 11 through the guide bin 12 under the action of the guide plate 804, and then output to the outside of the device through the material guide pipe 9. When the coal gasification ash slurry flows from the inside of the sealed cavity to the upper surface of the conveying filter screen 801, the transmission roller 803 in the second conveyor 8 rotates to drive the conveying filter screen 801 to transport the material, the turbine 805 fixedly connected with the transmission roller 803 rotates synchronously, the turbine 805 is engaged with the worm 2002, and the worm 2002 rotates synchronously. When the worm 2002 rotates, the two push-pull blocks 2003 slidingly installed on the reciprocating wire rod in the worm 2002 are respectively away from each other to the two ends of the rotating rod 2001, and then approach each other to the middle position of the worm 2002. Then, in the process of the two push-pull blocks 2003 continuously reciprocating, the two connecting rods 2004 can drive the swing rod 2005 to swing, the two ends of the swing rod 2005 are respectively in contact with the ends of the material guide plate 17 and the conveying filter screen 801, and the ends of the material guide plate 17 and the corresponding positions on the conveying filter screen 801 vibrate up and down in the process of the swing rod 2005 swinging back and forth. One end of the material guide plate 17 is rotatably connected with the lower end of the switching channel 15 on the inner wall of the processing box 3, and the inner wall of the processing box 3 below the connecting end of the material guide plate 17 is fixedly installed with a supporting block, so that the material guide plate 17 can only rotate upward around the active end as the axis, and the connecting part of the material guide plate 17 and the inner wall of the processing box 3 is provided with a waterproof rubber strip. The waterproof rubber strip can be deformed and is fixedly connected with the corresponding positions on the inner wall of the processing box 3 and the material guide plate 17 at both ends. When the material guide plate 17 vibrates up and down and the corresponding positions on the conveying filter screen 801 vibrate up and down, on the one hand, the material on the material guide plate 17 can fall faster, and on the other hand, the conveying filter screen 801 can assist and accelerate the screening of the falling coal gasification ash slurry.

[0059] When the magnetic separator 1 is used for dry separation of coal gasification ash, the dry coal gasification ash after extrusion and crushing is screened by the magnetic separator 1 to remove magnetic substances, and then enters the inside of the treatment box 3. Before the magnetic separator 1 is used for dry separation of coal gasification ash, the control assembly 16 drives the end of the switching channel 15 to slide in the switching channel 15 to block the cavity corresponding to the adding box 14, so that the spiral separator 2 arranged at the end of the switching channel 15 is in communication with the inside of the treatment box 3. When the control assembly 16 adjusts the position of the switching plate 25, the mounting plate 24 in the treatment box 3 can be adjusted by the synchronous assembly 19. Under the action of the synchronous assembly 19, the mounting plate 24 is flipped to make the blowing assembly 21 arranged on the other side face the switching channel 15. The blowing assembly 21 can blow the falling slurry. Under the action of the wind, the coal ash and light and small hollow glass beads in the dry coal gasification ash can be blown into the inside of the switching channel 15. The coal ash and light and small hollow glass beads are transported by the wind and enter the inside of the spiral separator 2 for separation. The lighter dust is output through the upper end of the spiral separator 2. The hollow glass beads heavier than the dust are output from the lower end of the spiral separator 2. The remaining coal gasification ash particles heavier than the dust and the hollow glass beads fall on the guide plate 17 arranged obliquely under the action of gravity. Under the guidance of the guide plate 17, the remaining coal gasification ash particles fall on the conveying filter screen 801 for screening and conveying. Under the action of the conveying filter screen 801, the remaining coal gasification ash particles can be screened again to separate the large particles and the small particles in the remaining coal gasification ash particles. When the guide plate 17 guides the remaining coal gasification ash from which the coal ash and the hollow glass beads are removed and the conveying filter screen 801 screens the remaining coal gasification ash, the two ends of the swing rod 2005 can also drive the ends of the guide plate 17 and the corresponding positions on the conveying filter screen 801 to vibrate, thereby assisting the unloading and screening of the coal gasification ash.

[0060] Meanwhile, the water inlet pipe 5 of the device introduces external water flow to clean the inside of the device. After the device is used for wet separation of coal gasification ash, part of the material can be adhered to various components in the inside of the device. The device separates the magnetic material, light and small material, coal ash, large particle material and small particle material in the coal gasification ash, so that the coal gasification ash can be separated and utilized according to the characteristics of the material after being treated by the device.
