Description

Technical Field

[0001] The present invention relates to the technical field of slag processing and production, and particularly relates to a grinding device for slag processing. Background Art

[0002] Slag is a by-product of the iron and steel industry. Specifically, in the process of blast furnace ironmaking, the impurities such as silicon dioxide and alumina in iron ore react with flux such as limestone to form a molten material, which is rapidly cooled by water quenching to form a granular solid material. Its main chemical components are calcium oxide, magnesium oxide, silicon oxide and alumina, which have potential hydraulicity. After being ground, it can be used as a cement admixture or a concrete admixture, and can also be used for producing components such as slag wool and aerated blocks, and is widely used. Before deep processing, it is necessary to use grinding equipment to grind and process the slag;

[0003] At present, in the process of grinding and processing slag, a ball mill is a commonly used slag grinding equipment. The internal cross-section of the existing ball mill is of a common circular specification. The rotating cylinder drives the steel balls and slag to rise and then fall, and the material is crushed through the dual actions of impact and grinding. In the actual use process, affected by factors such as the rotation speed of the drum and the quality of the steel balls, the steel balls will be thrown out before reaching the top position, and at this time the kinetic energy has not reached the maximum, which limits its processing efficiency during grinding and processing, increases the processing time, and after the existing ball mill grinds and processes the slag, it is also necessary to use a separator for separation. The unqualified materials need to be transferred to the inside of the ball mill again for secondary grinding by using transfer equipment, and the processing process is cumbersome. Therefore, a grinding device for slag processing is proposed. By improving the structure of the drum, the processing efficiency is improved, and at the same time, crushing treatment is used for secondary grinding, and the ground materials are separated, and the unqualified materials can be quickly discharged into the initial processing section for reprocessing. Summary of the Invention

[0004] Aiming at the problems in the prior art, the present invention provides a grinding device for slag processing. By improving the structure of the drum, the processing efficiency is improved, and at the same time, crushing treatment is used for secondary grinding, and the ground materials are separated, and the unqualified materials can be quickly discharged into the initial processing section for reprocessing.

[0005] The technical solution adopted by the present invention to solve its technical problems is a grinding device for slag processing, including a base. A drum for primary processing of slag is arranged on the top of the base. A feed hopper is vertically installed at the feed end of the drum, and a feed pipe extending into the drum is horizontally installed at the bottom end of the feed hopper. A processing box and a blower are arranged on the side of the base at the end of the drum;

[0006] At the middle position inside the drum, installation grooves are spaced apart. Inside each installation groove, a rotating shaft is installed, and an arc-shaped movable block is movably connected through the rotating shaft. The arc-shaped surface of the arc-shaped movable block has the same radian as the inner wall of the drum. On the surface of the arc-shaped movable block, away from the arc-shaped surface, a convex block extending to the outer periphery of the drum is integrally formed. A torsion spring is installed between the rotating position of the rotating shaft and the inner wall of the installation groove. At the middle position of the outer periphery of the drum on the top of the base, an arc-shaped limiting seat is fixedly connected, and the inner wall of the arc-shaped limiting seat is close to the outer wall of the drum;

[0007] By adopting the above technical solution, the drum rotates under the action of an external power device. The slag and the internally installed steel balls that enter it rotate with the drum. Installation grooves are spaced inside the drum, and arc-shaped movable blocks are connected through rotating shafts inside the installation grooves. The arc-shaped movable blocks can deflect within a certain angle around the rotating shafts. During the counterclockwise rotation of the drum, when the drum drives the internal steel balls and materials to rise to a certain height, due to the loss of the limitation of the arc-shaped limiting seat, under the action of the torsion spring, the arc-shaped movable blocks deflect. One end of them extends into the drum and forms a certain angle with the inner wall of the drum. At this time, the steel balls will be lifted by the end of the arc-shaped movable blocks, so that they cannot be thrown out in advance. Only when the arc-shaped movable blocks move with the drum to near the highest point, the steel balls will be thrown out. At this time, the steel balls fall and obtain the maximum force, improving the preliminary crushing effect on the slag and the crushing efficiency. After the steel balls are thrown out, at the position where the arc-shaped movable blocks are close to the arc-shaped limiting seat, the arc-shaped limiting seat will squeeze the convex blocks located on the outer periphery of the drum, and then the arc-shaped movable blocks are restricted and limited, and their arc-shaped surfaces are attached to the inner wall of the drum, enabling the steel balls and materials to fully contact and grind inside the drum. Compared with the existing ordinary ball mills, through the added movable components, the kinetic potential energy of the grinding medium is increased, thereby improving the grinding efficiency and quality.

[0008] Specifically, an arc-shaped support seat is welded at the bottom end inside the processing box. A motor is installed at one end of the processing box away from the drum, and the power output end of the motor is installed with a crushing roller located on the top of the arc-shaped support seat through a speed reducer. The air supply pipe extending to the bottom end inside the processing box is installed at the air exhaust end of the blower;

[0009] By adopting the above technical solution, the preliminarily ground qualified slag materials are blown into the processing box. Inside the processing box, the power end of the motor drives the continuous rotation of the crushing roller. After the materials enter the top of the arc-shaped support seat, using the cooperation of the arc-shaped support seat and the crushing roller, the materials are subjected to secondary grinding treatment to improve the fineness of the grinding. The wind generated by the operation of the blower is blown into the processing box from bottom to top, which can blow up the refined slag powder and blow it into the sorting box.

[0010] Specifically, a sorting box for screening the crushed slag is arranged on the top of the processing box. An inclined plate is welded obliquely inside the sorting box, and a conical discharge cylinder is welded at the top of the inclined plate. A filter plate is welded at the position on the top of the conical discharge cylinder inside the sorting box;

[0011] By adopting the above technical solution, after the powder material enters the inside of the sorting box, under the continuous blowing of the wind force, it passes through the inside of the conical discharge cylinder and approaches the filter plate. The slag powder material with qualified refinement degree will directly pass through the filter plate and be discharged, while the unqualified materials will be blocked by the filter plate and cannot be directly discharged.

[0012] Specifically, the top end of the air supply pipe is welded with an exhaust pipe extending to the side of the sorting box. An inclined conveying pipe is installed obliquely between the end of the sorting box side far from the exhaust pipe and the feed hopper. The side of the fiber separating box is welded with a fixing frame, and a hydraulic cylinder is installed on the surface of the fixing frame. The power output end of the hydraulic cylinder is installed with an adjusting plate, and both ends of the adjusting plate are inserted into the inside of the sorting box;

[0013] By adopting the above technical solution, the operation of the hydraulic cylinder can control the movement of the adjusting plate. The position of the adjusting plate controls the air flow direction inside the sorting box. During the normal screening process, the main body of the adjusting plate is inserted into the inside of the sorting box. At this time, both sides of the adjusting plate block the ends of the exhaust pipe and the conveying pipe respectively, and the wind force screens the materials. When it is necessary to recycle unqualified materials, the hydraulic cylinder runs to drive the adjusting plate to move outwards. The ends of the exhaust pipe and the conveying pipe are communicated with the inside of the sorting box. At this time, control the wind force of the fan to blow into the sorting box from the exhaust pipe, blow the unqualified materials into the conveying pipe and discharge them into the feed hopper through the conveying pipe, so that they can be ground again.

[0014] Specifically, supporting roller wheels are symmetrically installed on both sides of the roller at the top of the base. The bottom of the roller is attached to the surface of the supporting roller wheels. A toothed ring connected to an external power output device is welded at one end of the outer circumference of the roller;

[0015] By adopting the above technical solution, the supporting roller wheels arranged on the top of the base play a role in carrying and lifting the roller, and at the same time enable it to rotate smoothly. The output end of the external power device is installed with a gear meshing with the toothed ring. During operation, the external power device drives the gear to rotate, and drives the roller to rotate through the meshing of the gear and the toothed ring.

[0016] Specifically, through grooves are opened at positions on the surface of the roller corresponding to the installation grooves. The end of the convex block penetrates through the through groove and extends to the outer circumference of the roller. The protruding part of the convex block corresponds to the inner wall position of the arc-shaped limiting seat;

[0017] By adopting the above technical solution, the through groove structure enables the convex block on the side of the arc-shaped movable block to extend to the outer circumference of the roller in the unfolded state of the arc-shaped movable block, and adjusts its angle through the external arc-shaped limiting seat.

[0018] Specifically, a material guiding cover is provided at one end of the processing box close to the roller. The discharging end of the material guiding cover faces the position between the crushing roller and the arc-shaped support. An exhaust hole communicating with the exhaust end of the air supply pipe is formed inside the arc-shaped support. The bottom end of the air supply pipe is provided with a shunt pipe extending into the base, and the end of the shunt pipe extends to the end of the feed pipe.

[0019] By adopting the above technical solution, one side of the inlet end of the material guiding cover has a larger cross-sectional area and faces the inside of the roller, making it easier for the material to enter. One side of the discharging end of the material guiding cover has a smaller cross-sectional area and faces the position between the arc-shaped support and the crushing roller, enabling the material discharged from the roller to more easily enter the position between the arc-shaped support and the crushing roller. The exhaust hole structure allows the airflow blown by the air supply pipe to pass through the arc-shaped support, thereby blowing the crushed material upward. The end of the shunt pipe extends to the end of the feed pipe, and the wind blown out by the shunt pipe enters the inside of the roller. During the grinding process inside the roller, the refined material is blown into the material guiding cover.

[0020] Specifically, the inner diameter of the conical discharge cylinder gradually decreases from the inclined plate to the filter plate direction, and a discharge pipe is provided at the top of the sorting box.

[0021] By adopting the above technical solution, a conical discharge cylinder with a special specification is used. The large cross-sectional area at the inlet end allows the material to enter better, and the small cross-sectional area at the discharge end enables the screened material to fall onto the top of the inclined plate.

[0022] Specifically, a mounting seat A is welded horizontally on the side of the exhaust pipe. The end of the mounting seat A is installed with a cylinder A through bolts, and the power output end of the cylinder A is installed with a piston A inserted into the mounting seat A. A mounting seat B is welded on the top of the air supply pipe near the exhaust pipe. The top end of the mounting seat B is installed with a cylinder B through bolts, and the power output end of the cylinder B is installed with a piston B inserted into the mounting seat B.

[0023] By adopting the above technical solution, the operation of the cylinder A controls the position of the piston A. When it is inserted into the exhaust pipe, the air intake of the exhaust pipe can be closed, and when it is withdrawn, the airflow can enter the exhaust pipe. The operation of the cylinder B controls the position of the piston B. When it is inserted, the air supply pipe and the shunt pipe are closed, and when it is withdrawn, they are opened.

[0024] Specifically, the side positions of the adjusting plate are all attached to the inner wall of the sorting box, and the side positions of the adjusting plate correspond to the ends of the exhaust pipe and the conveying pipe respectively.

[0025] By adopting the above technical solution, it is ensured that the ends of the exhaust pipe and the conveying pipe can be exactly closed in the inserted state of the adjusting plate. At the same time, a sealing gasket assembly is provided at the connection position between the adjusting plate and the sorting box to prevent material and airflow leakage.

[0026] The beneficial effects of the present invention:

[0027] (1) In the grinding device for slag processing according to the present invention, when the roller drives the internal steel balls and materials to rise in height, due to the loss of the limit of the arc-shaped limit seat, the arc-shaped movable block deflects under the action of the torsion spring, and one end of it extends into the roller and forms a certain angle with the inner wall of the roller. At this time, the steel balls will be lifted by the end of the arc-shaped movable block, so that they cannot be thrown out in advance. Only when the arc-shaped movable block moves with the roller to near the highest point, the steel balls will be thrown out. At this time, the steel balls fall and obtain the maximum force, improving the initial crushing effect on the slag. The arc-shaped limit seat will squeeze the convex blocks located on the outer circumference of the roller, and then the arc-shaped movable block is restricted and limited, so that the steel balls and materials can fully contact and grind inside the roller. By adding the movable assembly, the movement potential energy of the grinding medium is increased, and thus the grinding efficiency and quality are improved.

[0028] (2) In the grinding device for slag processing according to the present invention, after the materials enter the top of the arc-shaped support, the arc-shaped support and the crushing roller are used in cooperation to perform secondary grinding on the materials, improving the fineness of the grinding. The wind generated by the operation of the fan blows upward into the processing box from the bottom, and can blow up the refined slag powder and blow it into the sorting box. After the powder enters the sorting box, under the continuous blowing of the wind, it passes through the internal part of the conical discharge tube and approaches the filter plate. The slag powder with qualified fineness will directly pass through the filter plate and be discharged, while the unqualified materials will be blocked by the filter plate and cannot be directly discharged.

[0029] (3) In the grinding device for slag processing according to the present invention, the position of the adjusting plate controls the wind flow direction inside the sorting box. During the normal screening process, the main body of the adjusting plate is inserted into the sorting box, and the wind screens the materials. When it is necessary to recycle the unqualified materials, the hydraulic cylinder operates to drive the adjusting plate to move outwards. The ends of the exhaust pipe and the conveying pipe are communicated with the inside of the sorting box. At this time, the opening and closing of the air supply pipe and the exhaust pipe are adjusted. The air supply pipe is closed, the exhaust pipe is opened, and the wind of the fan is controlled to be blown into the sorting box from the exhaust pipe, blowing the unqualified materials into the conveying pipe and discharging them into the feed hopper through the conveying pipe, so that they are re-ground, realizing automatic sorting and reprocessing.

Detailed implementation manners

[0039] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0040] Embodiment 1:

[0041] The technical solution adopted by the present invention to solve its technical problems is a grinding powder device for slag processing, including a base 1. A drum 201 for primary slag processing is arranged at the top of the base 1. A feed hopper 203 is vertically installed at the feed end of the drum 201, and a feed pipe 204 extending into the drum 201 is horizontally installed at the bottom end of the feed hopper 203. A processing box 4 and a fan 5 are arranged at the side of the base 1 at the end position of the drum 201;

[0042] An installation groove 3 is provided at an interval in the middle position inside the roller 201. A rotating shaft 302 is installed inside each of the installation grooves 3, and an arc-shaped movable block 303 is movably connected through the rotating shaft 302. The arc surface of the arc-shaped movable block 303 has the same radian as the inner wall of the roller 201. A convex block 304 extending to the outer periphery of the roller 201 is integrally formed on one side of the surface of the arc-shaped movable block 303 away from the arc surface. A torsion spring 305 is installed between the rotating position of the rotating shaft 302 and the inner wall of the installation groove 3. A arc-shaped limiting seat 306 is fixedly connected to the top of the base 1 at the middle position of the outer periphery of the roller 201, and the inner wall of the arc-shaped limiting seat 306 is close to the outer wall of the roller 201;

[0043] During use, the roller 201 rotates under the action of an external power device. The slag and the internally built steel balls that enter it rotate with the roller 201. Installation grooves 3 are provided at intervals inside the roller 201, and arc-shaped movable blocks 303 are connected inside the installation grooves 3 through rotating shafts 302. The arc-shaped movable blocks 303 can deflect around the rotating shafts 302 within a certain angle. During the counterclockwise rotation of the roller 201, when the roller 201 drives the internal steel balls and materials to rise to a certain height, due to the loss of the limit of the arc-shaped limiting seat 306, the arc-shaped movable blocks 303 deflect under the action of the torsion spring 305. One end of it extends into the interior of the roller 201 and forms a certain angle with the inner wall of the roller 201. At this time, the steel balls will be lifted by the end of the arc-shaped movable block 303, so that they cannot be thrown out in advance. Only when the arc-shaped movable blocks 303 move with the roller 201 to near the highest point, the steel balls will be thrown out. At this time, the steel balls fall and obtain the maximum force, improving the preliminary crushing effect on the slag and improving the crushing efficiency. After the steel balls are thrown out, the arc-shaped movable blocks 303 are close to the arc-shaped limiting seat 306. The arc-shaped limiting seat 306 will squeeze the convex blocks 304 located on the outer periphery of the roller 201, and then the arc-shaped movable blocks 303 are restricted and limited, and their arc surfaces are attached to the inner wall of the roller 201, so that the steel balls and materials can fully contact and grind inside the roller 201. Compared with the existing ordinary ball mill, by adding an additional movable component, the movement potential energy of the grinding medium is increased, and thus the grinding efficiency and quality are improved.

[0044] Specifically, an arc-shaped support seat 402 is welded to the bottom end inside the processing box 4. A motor 403 is installed at one end of the processing box 4 away from the roller 201, and a crushing roller 404 located on the top of the arc-shaped support seat 402 is installed at the power output end of the motor 403 through a speed reducer. An air supply pipe 501 extending to the bottom end inside the processing box 4 is installed at the exhaust end of the air blower 5;

[0045] During use, the slag material that has passed the preliminary grinding is blown into the interior of the processing box 4. When inside the processing box 4, the power end of the motor 403 drives the continuous rotation of the crushing roller 404. After the material enters the top of the arc-shaped support 402, by using the cooperation between the arc-shaped support 402 and the crushing roller 404, the material is subjected to secondary pulverization treatment to improve the fineness of the pulverization. The wind generated by the operation of the blower 5 is blown upward into the interior of the processing box 4, which can blow up the refined slag powder and blow it into the sorting box 6.

[0046] Specifically, a sorting box 6 for screening crushed slag is provided at the top of the processing box 4. An inclined plate 601 is welded obliquely inside the sorting box 6, and a conical discharge cylinder 602 is welded to the top of the inclined plate 601. A filter plate 603 is welded inside the sorting box 6 at the position above the conical discharge cylinder 602.

[0047] During use, after the powder enters the sorting box 6, under the continuous blowing of the wind, it passes through the conical discharge cylinder 602 and approaches the filter plate 603. The slag powder with qualified fineness will directly pass through the filter plate 603 and be discharged, while the unqualified materials will be blocked by the filter plate 603 and cannot be directly discharged.

[0048] Specifically, support rollers 2 are symmetrically installed on both sides of the roller 201 at the top of the base 1. The bottom of the roller 201 is in contact with the surface of the support rollers 2. A toothed ring 202 connected to an external power output device is welded to one end of the outer circumference of the roller 201.

[0049] During use, the support rollers 2 provided on the top of the base 1 play a role in supporting and lifting the roller 201, and at the same time enable it to rotate smoothly. The output end of the external power device is equipped with a gear meshing with the toothed ring 202. During operation, the external power device drives the gear to rotate, and through the meshing of the gear and the toothed ring 202, the roller 201 is driven to rotate.

[0050] Specifically, through grooves 301 are opened at the positions corresponding to the mounting grooves 3 on the surface of the roller 201. The end of the convex block 304 penetrates through the through groove 301 and extends to the outer circumference of the roller 201. The protruding part of the convex block 304 corresponds to the inner wall position of the arc-shaped limiting seat 306.

[0051] During use, the structure of the through groove 301 enables the convex block 304 on the side of the arc-shaped movable block 303 to extend to the outer circumference of the roller 201 in the unfolded state of the arc-shaped movable block 303, and its angle can be adjusted by the external arc-shaped limiting seat 306.

[0052] Specifically, a material guiding cover 401 is provided inside the processing box 4 near one end of the roller 201. The discharge end of the material guiding cover 401 faces the position between the crushing roller 404 and the arc-shaped support 402. An exhaust hole 502 communicating with the exhaust end of the air supply pipe 501 is formed inside the arc-shaped support 402. The bottom end of the air supply pipe 501 is provided with a shunt pipe 503 extending into the base 1, and the end of the shunt pipe 503 extends to the end of the feed pipe 204.

[0053] During use, the cross-sectional area of one side of the inlet end of the structure of the material guiding cover 401 is larger and faces the inside of the roller 201, making it easier for the material to enter. The cross-sectional area of one side of the discharge end of the material guiding cover 401 is smaller and faces the position between the arc-shaped support 402 and the crushing roller 404, which can make the material discharged from the roller 201 more likely to enter the position between the arc-shaped support 402 and the crushing roller 404. The structure of the exhaust hole 502 enables the airflow blown into by the air supply pipe 501 to pass through the arc-shaped support 402, thereby blowing the crushed material upward. The end of the shunt pipe 503 extends to the end of the feed pipe 204, and the wind blown out by the shunt pipe 503 enters the inside of the roller 201. During the grinding process inside the roller 201, the refined material is blown into the inside of the material guiding cover 401.

[0054] During use, the drum 201 rotates under the action of an external power device. The slag and the steel balls built inside it that enter the drum 201 rotate with the drum 201. Installation grooves 3 are arranged at intervals inside the drum 201, and an arc-shaped movable block 303 is connected to the inside of the installation groove 3 through a rotating shaft 302. The arc-shaped movable block 303 can deflect within a certain angle around the rotating shaft 302. During the counterclockwise rotation of the drum 201, when the drum 201 drives the internal steel balls and materials to rise in height, due to the loss of the limit of the arc-shaped limit seat 306, the arc-shaped movable block 303 deflects under the action of the torsion spring 305, and one end of it extends into the drum 201 and forms a certain angle with the inner wall of the drum 201. At this time, the steel ball will be lifted by the end of the arc-shaped movable block 303, making it impossible to be thrown out in advance. Only when the arc-shaped movable block 303 moves with the drum 201 to a position close to the highest point, the steel ball will be thrown out. At this time, the steel ball falls and obtains the maximum force, improving the preliminary crushing effect on the slag and the crushing efficiency. After the steel ball is thrown out, the arc-shaped movable block 303 is close to the arc-shaped limit seat 306. The arc-shaped limit seat 306 will squeeze the convex block 304 located on the outer circumference of the drum 201, and then the arc-shaped movable block 303 is restricted and limited, and its arc surface fits the inner wall of the drum 201, enabling the steel balls and materials to be in full contact and grinding inside the drum 201. Compared with the existing ordinary ball mill, through the added movable components, the movement and potential energy of the grinding medium are improved, thereby improving the grinding efficiency and quality. The slag materials that pass the preliminary grinding are blown into the processing box 4. When inside the processing box 4, the power end of the motor 403 drives the continuous rotation of the crushing roller 404. When the materials enter the top of the arc-shaped support 402, the arc-shaped support 402 and the crushing roller 404 are used in cooperation to perform secondary grinding on the materials, improving the fineness of the grinding. The wind generated by the operation of the fan 5 blows into the processing box 4 from bottom to top, which can blow up the refined slag powder and blow it into the sorting box 6. After the powder enters the sorting box 6, under the continuous blowing of the wind, it passes through the conical discharge cylinder 602 and approaches the filter plate 603. The slag powder with qualified fineness will directly pass through the filter plate 603 and be discharged, while the unqualified materials will be blocked by the filter plate 603 and cannot be directly discharged.

[0055] Embodiment 2:

[0056] The technical solution adopted by the present invention to solve its technical problems is a grinding and powdering device for slag processing, including a base 1. A drum 201 for preliminary slag processing is arranged on the top of the base 1. A feed hopper 203 is installed in the vertical direction at the feed end of the drum 201, and a feed pipe 204 extending into the drum 201 is installed in the horizontal direction at the bottom end of the feed hopper 203. A processing box 4 and a fan 5 are arranged on the side of the base 1 at the end position of the drum 201;

[0057] A mounting groove 3 is spaced and provided at the middle position inside the drum 201. A rotating shaft 302 is installed inside each of the mounting grooves 3, and an arc-shaped movable block 303 is movably connected through the rotating shaft 302. The arc surface of the arc-shaped movable block 303 has the same radian as the inner wall of the drum 201. A convex block 304 extending to the outer periphery of the drum 201 is integrally formed on one side of the surface of the arc-shaped movable block 303 away from the arc surface. A torsion spring 305 is installed between the rotating position of the rotating shaft 302 and the inner wall of the mounting groove 3. The top of the base 1 is fixedly connected with an arc-shaped limiting seat 306 at the middle position of the outer periphery of the drum 201, and the inner wall of the arc-shaped limiting seat 306 is close to the outer wall of the drum 201;

[0058] During use, the drum 201 rotates under the action of an external power device. The slag entering its interior and the steel balls built in it rotate with the drum 201. Mounting grooves 3 are spaced inside the drum 201, and arc-shaped movable blocks 303 are connected through rotating shafts 302 inside the mounting grooves 3. The arc-shaped movable blocks 303 can deflect around the rotating shafts 302 within a certain angle. During the counterclockwise rotation of the drum 201, when the drum 201 drives the internal steel balls and materials to rise in height, due to the loss of the limit of the arc-shaped limiting seat 306, the arc-shaped movable blocks 303 deflect under the action of the torsion spring 305. One end of it extends into the interior of the drum 201 and forms a certain angle with the inner wall of the drum 201. At this time, the steel balls will be lifted by the end of the arc-shaped movable block 303, so that they cannot be thrown out in advance. Only when the arc-shaped movable blocks 303 move with the drum 201 to near the highest point, the steel balls will be thrown out. At this time, the steel balls fall and obtain the maximum force, improving the preliminary crushing effect on the slag and the crushing efficiency. After the steel balls are thrown out, the arc-shaped movable blocks 303 are close to the arc-shaped limiting seat 306. The arc-shaped limiting seat 306 will squeeze the convex blocks 304 located on the outer periphery of the drum 201, and then the arc-shaped movable blocks 303 are restricted and limited, and their arc surfaces are attached to the inner wall of the drum 201, so that the steel balls and materials can fully contact and grind inside the drum 201. Compared with the existing ordinary ball mill, by adding the movable components, the movement potential energy of the grinding medium is increased, and thus the grinding efficiency and quality are improved.

[0059] Specifically, an arc-shaped support 402 is welded to the bottom end inside the processing box 4. A motor 403 is installed at one end of the processing box 4 away from the drum 201, and a crushing roller 404 located on the top of the arc-shaped support 402 is installed at the power output end of the motor 403 through a speed reducer. The air supply pipe 501 extending to the bottom end inside the processing box 4 is installed at the exhaust end of the air blower 5;

[0060] During use, the slag material that has passed the preliminary grinding is blown into the interior of the processing box 4. When inside the processing box 4, the power end of the motor 403 drives the continuous rotation of the crushing roller 404. After the material enters the top of the arc-shaped support 402, the cooperation between the arc-shaped support 402 and the crushing roller 404 is used to perform secondary grinding on the material, improving the fineness of the grinding. The wind generated by the operation of the fan 5 is blown upward into the interior of the processing box 4, which can blow up the refined slag powder and blow it into the sorting box 6.

[0061] Specifically, a sorting box 6 for screening crushed slag is provided at the top of the processing box 4. An inclined plate 601 is welded obliquely inside the sorting box 6, and a conical discharge cylinder 602 is welded at the top of the inclined plate 601. A filter plate 603 is welded inside the sorting box 6 at the position above the conical discharge cylinder 602.

[0062] During use, after the powder enters the sorting box 6, under the continuous blowing of the wind, it passes through the conical discharge cylinder 602 and approaches the filter plate 603. The slag powder with qualified fineness will directly pass through the filter plate 603 and be discharged, while the unqualified materials will be blocked by the filter plate 603 and cannot be directly discharged.

[0063] Specifically, the top end of the air supply pipe 501 is welded with an exhaust pipe 7 extending to the side of the sorting box 6. A conveying pipe 701 is obliquely installed between the end of the sorting box 6 away from the exhaust pipe 7 and the feed hopper 203. A fixed frame 708 is welded to the side of the fiber separating box, and a hydraulic cylinder 709 is installed on the surface of the fixed frame 708. The power output end of the hydraulic cylinder 709 is installed with an adjusting plate 710, and both ends of the adjusting plate 710 are inserted into the sorting box 6.

[0064] During use, the operation of the hydraulic cylinder 709 can control the movement of the adjusting plate 710. The position of the adjusting plate 710 controls the air flow direction inside the sorting box 6. During normal screening, the main body of the adjusting plate 710 is inserted into the sorting box 6. At this time, both sides of the adjusting plate 710 block the ends of the exhaust pipe 7 and the conveying pipe 701 respectively, and the wind screens the material. When it is necessary to recycle unqualified materials, the hydraulic cylinder 709 operates to drive the adjusting plate 710 to move outward. The ends of the exhaust pipe 7 and the conveying pipe 701 are communicated with the inside of the sorting box 6. At this time, the wind of the fan 5 is controlled to be blown into the sorting box 6 from the exhaust pipe 7, blowing the unqualified materials into the conveying pipe 701 and discharging them into the feed hopper 203 through the conveying pipe 701 to re-perform the grinding process.

[0065] Specifically, the inner diameter of the conical discharge cylinder 602 gradually decreases from the inclined plate 601 to the filter plate 603 direction. A discharge pipe 604 is provided at the top of the sorting box 6.

[0066] During use, a conical discharge tube 602 with special specifications is adopted. The cross-sectional area of its inlet end is large, enabling the material to enter better, and the cross-sectional area of the outlet end is small, allowing the screened material to fall onto the top of the inclined plate 601.

[0067] Specifically, a mounting seat A702 is welded horizontally on the side of the exhaust duct 7. The end of the mounting seat A702 is provided with a cylinder A703 through bolts, and the power output end of the cylinder A703 is provided with a piston A704 inserted into the inside of the mounting seat A702. A mounting seat B705 is welded at a position near the exhaust duct 7 on the top of the air supply duct 501. The top of the mounting seat B705 is provided with a cylinder B706 through bolts, and the power output end of the cylinder B706 is provided with a piston B707 inserted into the inside of the mounting seat B705.

[0068] During use, the operation of the cylinder A703 controls the position of the piston A704. When it is inserted into the exhaust duct 7, the air inlet of the exhaust duct 7 can be closed, and when it is withdrawn, air flow can enter the inside of the exhaust duct 7. The operation of the cylinder B706 controls the position of the piston B707. When it is inserted, the air supply duct 501 and the shunt duct 503 are closed, and when it is withdrawn, they are opened.

[0069] Specifically, the side positions of the adjusting plate 710 are all attached to the inner wall of the sorting box 6, and the side positions of the adjusting plate 710 correspond to the ends of the exhaust duct 7 and the conveying pipe 701 respectively.

[0070] During use, it is ensured that when the adjusting plate 710 is in the inserted state, it can exactly close the ends of the exhaust duct 7 and the conveying pipe 701. At the same time, a sealing gasket assembly is provided at the connection position between the adjusting plate 710 and the sorting box 6 to prevent material and air leakage.

[0071] During use, the operation of the hydraulic cylinder 709 can control the movement of the adjusting plate 710. The position of the adjusting plate 710 controls the air flow direction inside the sorting box 6. During the normal screening process, the main body of the adjusting plate 710 is inserted into the sorting box 6. At this time, both sides of the adjusting plate 710 block the ends of the exhaust duct 7 and the conveying pipe 701 respectively, and the air screens the materials. When it is necessary to recover the unqualified materials, the hydraulic cylinder 709 operates to drive the adjusting plate 710 to move outward. The ends of the exhaust duct 7 and the conveying pipe 701 are communicated with the inside of the sorting box 6. At this time, the air volume of the fan 5 is controlled to be blown into the sorting box 6 from the exhaust duct 7, and the unqualified materials are blown into the conveying pipe 701 and discharged into the feed hopper 203 by the conveying pipe 701 to re-perform the grinding process. A special specification conical discharge cylinder 602 is adopted. The large cross-sectional area of its inlet end enables the materials to enter better, and the small cross-sectional area of the discharge end enables the screened materials to fall onto the top of the inclined plate 601. The operation of the cylinder A 703 controls the position of the piston A 704. When it is inserted into the exhaust duct 7, it can close the air inlet of the exhaust duct 7, and when it is withdrawn, it can enable the air flow to enter the exhaust duct 7. The operation of the cylinder B 706 controls the position of the piston B 707. When it is inserted, it closes the air supply pipe 501 and the shunt pipe 503, and when it is withdrawn, it opens them, ensuring that the ends of the exhaust duct 7 and the conveying pipe 701 can be exactly closed in the inserted state of the adjusting plate 710. At the same time, a sealing gasket assembly is provided at the connection position between the adjusting plate 710 and the sorting box 6 to prevent material and air leakage.
