[0002] Cement aggregates refer to granular materials such as sand and stone that are mixed with cement and water when making mortar or concrete. In the production process of cement aggregates, the raw materials need to be ground into powder by grinding equipment before they can be used for mixing in concrete.

When processing raw materials in a vertical mill, a large amount of raw materials are poured in and fill the entire loading tray. However, the crushing range of the crushing roller is limited, and the accumulation of materials makes it difficult for some materials to participate in the crushing operation, affecting the crushing effect; 2.

The front and rear ends of the plurality of baffles are fixedly connected to a rotating shaft. The rear walls of the plurality of baffles are fixedly connected to a gear column, and the top ends of the plurality of gear columns are meshed with the same external gear ring. The ends of the gear columns are fixedly connected to the side wall of the threaded rod.

[0017] A method for using a slag vertical mill for cement aggregate production includes the following steps:

[0018] S1. With the start of the device, the power of the drive motor is transmitted to the drive wheel and the loading plate through the spring telescopic rod with spline structure. A large number of fine stones enter the inner cylinder. With the rotation of the loading plate, the loading plate moves the stones toward the crushing wheel. The crushing wheel crushes the stones and continuously pulverizes them.

[0019] S2. Simultaneously, the drive wheel device drives the internal gear ring slowly through the driven wheel. The rotation of the internal gear ring synchronously drives the upper trigger plate to rotate. Since the gear plate has an inner groove, the gear plate is stuck by one of the limit blocks. When the trigger plate gradually contacts the stuck limit block, the trigger plate squeezes the limit block and moves it out of the inner groove. At the same time, the blocking rod on the trigger plate is squeezed. Since the connection structure between the blocking rod and the air chamber is the same as the connection structure between the piston rod and the regulating chamber, the blocking rod retracts inward when squeezed by the limit block, causing the moving plate at the bottom of the blocking rod to move out of the limit groove. When the trigger plate leaves the limit block, it is released by the spring and reset from the W-shaped groove to the V-shaped groove. At this time, the blocking rod produces a backward pulling action. The rear end of the blocking rod pulls the movable sleeve down through the push rod, causing the spring telescopic rod to enter the retracted state. As the spring telescopic rod moves down, the push rod above it moves down and drives the threaded sleeve to rotate in the opposite direction.

[0020] S3. As the threaded sleeve rotates in the opposite direction, the threaded sleeve drives the first triangular plate to rotate. Through the setting of the pulling rod and the positioning rod, the cleaning plate is driven to retract inward. When the cleaning plate is stored in the receiving box, the cleaning plate will squeeze the movable door and retract in the inner wall of the release groove. The rearward movement of the movable door generates air pressure to push the piston rod in the fixed rod forward. Since the connection structure between the blocking rod and the air chamber is the same as the connection structure between the piston rod and the adjustment chamber, as described in step S2, the moving plate at the bottom of the piston rod enters the V-shaped groove from the W-shaped groove. At this time, the piston rod moves backward and resets, which reduces the pressure in the air chamber and transmits the pressure in the sealing chamber to the air chamber. After the airflow passes through the pneumatic motor, it pushes the unfolded guide plate to rotate counterclockwise and enter the arc-shaped groove.

[0021] S4. Simultaneously triggered by the trigger plate and limit block, when the gear plate rotates, the gear plate synchronously drives the rotating disk. As the rotating disk rotates one revolution, the L-shaped rod located on the rotating disk gradually moves from the inner annular groove towards the guide block, and squeezes the guide block to cover the annular groove side of the outer teeth, so that the L-shaped rod can move into the outer annular groove. At the same time, the L-shaped rod moves forward, driving the sliding sleeve to move synchronously. The forward movement pushes the threaded rod to rotate. The threaded rod drives the outer gear ring to rotate through the gear column. The outer gear ring then synchronously drives several other sets of gear columns to rotate. The rotation of the gear column can drive the baffle plate to open, so that the material falls at this time. At the same time, the cleaning plate and the guide plate are in the reset and retracted state, which will not affect the normal use of the equipment.

[0022] S5. Finally, when the trigger plate triggers the limit block again, the blocking rod on the trigger plate will push the movable sleeve to drive the spring telescopic rod to extend vertically, which in turn causes the push rod to move upward and push the threaded sleeve to drive the first triangular plate to rotate, causing several cleaning plates to squeeze the movable door to open and unfold. At the same time, the opening of the movable door squeezes the piston rod, and the forward movement of the piston rod generates air pressure to push the high-pressure airflow through the pneumatic motor, which pushes the guide plate to rotate clockwise, open, and divert the airflow for cleaning operation.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] In this invention, the controllable cleaning plate can be automatically opened after the material is discharged. When the loading plate moves the material, it can push the material towards the crushing zone of the crushing roller, thus avoiding the accumulation of material and preventing some material from being unable to participate in the crushing operation.

[0025] In this invention, by setting up the guide plate, the cleaning plate can be opened and simultaneously deployed to guide the airflow towards the loading plate, so that the material dust adhering to the loading plate can be blown away and collected, avoiding a large amount of adhesion that affects the crushing effect.

[0026] In this invention, by setting a controllable feeding mechanism, the feeding can be stopped after feeding in a timed and quantitative manner, and the raw materials can be finely ground to avoid excessive accumulation of materials, which would affect the crushing efficiency.

[0046] A number of fixed rods 310 arranged in a ring array are fixedly connected to the outer wall of the receiving box 31, and an adjustment chamber 311 is fixedly connected to the bottom end of the fixed rod 310. The inner cavity of the fixed rod 310 is connected to the inside of the release groove 38, and a guide 312 is provided on one side of the fixed rod 310.

[0047] An air chamber 313 is provided in the inner wall of the fixed rod 310. A piston rod 314 is slidably connected in the inner wall of the air chamber 313. A slider is fixedly connected to the bottom end of the piston rod 314 and extends into the inner wall of the adjustment chamber 311.

The output end of the pneumatic motor 3124 is connected to a sealing chamber 3125. The input end of the pneumatic motor 3124 is connected to the end of the fixed rod 310, so that after the material is discharged, the cleaning plate 35 opens and drives the guide plate 3123 to open, guiding the airflow to clean the loading tray 5.

[0052] In this embodiment, as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the converging mechanism 3 also includes a power chamber 319, which is located in the inner wall of the outer shell 1. A drive motor is fixedly connected to the bottom wall of the power chamber 319. A drive wheel 320 is fixedly connected to the shaft end of the drive motor. A driven wheel 321 meshes with the outer wall of the drive wheel 320. An internal gear ring 322 meshes with one side of the driven wheel 321. A gear disc 323 is fixedly connected to the top of the internal gear ring 322. An inner groove 324 is provided on the outer wall of the gear disc 323. Several limiting blocks 325 are arranged in a circular array on the outer wall of the gear disc 323. The outer walls of the several limiting blocks 325 are slidably connected to the inner wall of the power chamber 319. A return spring is fixedly connected to the end of the several limiting blocks 325. The outer diameter of the limiting block 325 matches the inner diameter of the inner groove 324.

[0053] A trigger plate 326 is fixedly connected to the top of the gear disc 323. The trigger plate 326 and the limiting block 325 are horizontally arranged. A tension spring 327 is fixedly connected to the outer wall of the trigger plate 326, and the end of the tension spring 327 is fixedly connected to the top of the gear disc 323. An air chamber 328 is fixedly connected to the top of the trigger plate 326, and a blocking rod 329 is slidably connected to the inner wall of the air chamber 328. Two sets of blocking rods 329 are symmetrically arranged about the axis of the air chamber 328. A top plate 330 is hinged to the end of the blocking rod 329, and a movable sleeve 331 is hinged to the top of the top plate 330. A spring telescopic rod 332 is fixedly connected to the inner wall of the movable sleeve 331. A spline is provided on the outer wall of the movable end of the spring telescopic rod 332. The top end of the spring telescopic rod 332 is connected to the inner wall of the loading tray 5 through the spline. A push rod 333 is rotatably connected to the top end of the spring telescopic rod 332, and the inner wall of the push rod 333 is threadedly connected to the inner wall of the threaded sleeve 32. The bottom end of the spring telescopic rod 332 is connected to the main shaft of the drive motor. The staggered opening of the cleaning plate 35 and the baffle plate 48 is controlled by the setting of four sets of limit blocks 325 and toothed disc 323, which facilitates the use of the device.

[0054] In this embodiment, as Figure 5 , Figure 6 and Figure 14 As shown, the feeding mechanism 4 includes a rotating disk 41, which is rotatably connected to the inner wall of the power chamber 319. The rotating disk 41 meshes with the gear disk 323. Two sets of annular grooves 42 are provided in the inner wall of the rotating disk 41. The two sets of annular grooves 42 are concentrically arranged and have different radii. The top of the rotating disk 41 is rotatably connected to two sets of guide blocks 43 by a torsion spring. The two sets of guide blocks 43 are respectively arranged on one side of the two sets of annular grooves 42.

[0055] An L-shaped plate 44 is slidably connected to the inner wall of the annular groove 42. A pull plate is fixedly connected to the top of the L-shaped plate 44, and a sliding sleeve 45 is fixedly connected to the top of the pull plate. A threaded rod 46 is threadedly connected to the inner wall of the sliding sleeve 45. With the setting of the rotating disk 41, the movement of the L-shaped plate 44 can be triggered each time the gear disk 323 rotates, so as to control the opening and closing of the baffle plate 48 through the L-shaped plate 44.

[0056] In this embodiment, as Figure 14 and Figure 15 As shown, the feeding mechanism 4 also includes a feeding bin 47, which is fixedly installed in the inner wall of the inner cylinder 2. Several baffles 48 are arranged in a circular array at equal intervals on the inner wall of the feeding bin 47, and the front and rear ends of the several baffles 48 are fixedly connected to rotating shafts. Gear columns 49 are fixedly connected to the rear walls of the several baffles 48, and the top ends of the several gear columns 49 are meshed with the same external gear ring 410. The ends of the gear columns 49 are fixedly connected to the side wall of the threaded rod 46. By setting several baffles 48, the material can be shielded and the material conveying can be stopped, which facilitates the combined operation of the discharging mechanism and the converging mechanism 3.

[0057] In this embodiment, as Figures 1 to 15 As shown, a method for using a slag vertical mill for cement aggregate production includes the following steps:

[0058] S1. With the start of the device, the power of the drive motor is transmitted to the drive wheel 320 and the loading plate 5 through the spring telescopic rod 332 with spline structure. A large number of fine stones enter the inner cylinder 2. With the rotation of the loading plate 5, the loading plate 5 drives the stones to move towards the crushing wheel. The crushing wheel crushes the stones and continuously pulverizes them.

[0059] S2. Simultaneously, the drive wheel 320 drives the internal gear ring 322 slowly via the driven wheel 321. The rotation of the internal gear ring 322 synchronously drives the upper trigger plate 326 to rotate. Because the gear disc 323 has an inner groove 324, the gear disc 323 is stuck by one of the limiting blocks 325. When the trigger plate 326 gradually contacts the stuck limiting block 325, the trigger plate 326 squeezes the limiting block 325 and moves it out of the inner groove 324. At the same time, the blocking rod 329 on the trigger plate 326 is squeezed. Due to the connection structure between the blocking rod 329 and the air chamber 328 and the piston rod 314 and the adjustment... The connection structure of chamber 311 is the same, so that when the blocking rod 329 is squeezed by the limiting block 325, it retracts inward, causing the moving plate 318 at the bottom of the blocking rod 329 to move out of the limiting groove 317. When the trigger plate 326 leaves the limiting block 325, it is released by the spring and reset from the W-shaped groove 316 to the V-shaped groove. At this time, the blocking rod 329 produces a backward pulling action. The rear end of the blocking rod 329 pulls the movable sleeve 331 down through the push rod, causing the spring telescopic rod 332 to enter the retracted state. As the spring telescopic rod 332 moves down, the push rod 333 above it moves down and drives the threaded sleeve 32 to rotate in the opposite direction.

[0060] S3. With the reverse rotation of the threaded sleeve 32, the threaded sleeve 32 drives the first triangular plate 33 to rotate. Through the setting of the pulling rod 34 and the positioning rod 36, the cleaning plate 35 is driven to retract inward. When the cleaning plate 35 is stored in the receiving box 31, the cleaning plate 35 will squeeze the movable door 39 and retract it in the inner wall of the release groove 38. The backward movement of the movable door 39 generates air pressure to push the piston rod 314 in the fixed rod 310 forward. Due to the connection structure between the blocking rod 329 and the air chamber 328 and the piston... The connection structure between the piston rod 314 and the regulating chamber 311 is the same as described in step S2. The moving plate 318 at the bottom of the piston rod 314 enters the V-shaped groove 315 from the W-shaped groove 316. At this time, the piston rod 314 moves backward and resets, which reduces the pressure in the air chamber 313 and transmits the pressure in the sealing chamber 3125 to the air chamber 313. After the airflow passes through the pneumatic motor 3124, it pushes the unfolded guide plate 3123 to rotate counterclockwise and enter the arc-shaped groove 3122.

[0061] S4. Simultaneously triggered by the trigger plate 326 and the limit block 325, when the gear plate 323 rotates, the gear plate 323 synchronously drives the rotating plate 41. When the rotating plate 41 rotates once, the L-shaped rod on the rotating plate 41 gradually moves from the inner annular groove 42 towards the guide block 43, and squeezes the guide block 43 to block the outer annular groove 42 side of the gear, so that the L-shaped rod can move into the outer annular groove 42. At the same time, the L-shaped rod moves forward, driving the sliding sleeve 45 to move synchronously. Moving forward pushes the threaded rod 46 to rotate. The threaded rod 46 drives the outer gear ring 410 to rotate through the gear column 49. The outer gear ring 410 then synchronously drives several other sets of gear columns 49 to rotate. The rotation of the gear column 49 can drive the baffle plate 48 to open, so that the material falls at this time. At the same time, the cleaning plate 35 and the guide plate 3123 are in the reset and retracted state, which will not affect the normal use of the equipment.

[0062] S5. Finally, when the trigger plate 326 triggers the limit block 325 again, the blocking rod 329 on the trigger plate 326 will push the movable sleeve 331 to drive the spring telescopic rod 332 to extend vertically, thereby causing the push rod 333 to move upward and push the threaded sleeve 32 to drive the first triangular plate 33 to rotate, so that several cleaning plates 35 squeeze the movable door 39 to open and unfold. At the same time, the opening of the movable door 39 squeezes the piston rod 314. The piston rod 314 moves forward and generates air pressure to push the high-pressure airflow through the pneumatic motor 3124, pushing the guide plate 3123 to rotate clockwise and open, diverting the airflow for cleaning operation.

8. The method of using a slag vertical mill for cement aggregate production according to claim 1, characterized in that: Includes the following steps: S1. With the start of the device, the power of the drive motor is transmitted to the drive wheel (320) and the loading plate (5) through the spring telescopic rod (332) with spline structure. A large number of fine stones enter the inner cylinder (2). With the rotation of the loading plate (5), the loading plate (5) drives the stones to move towards the crushing wheel. The crushing wheel will crush the stones and continuously crush them. S2. Simultaneously with the drive wheel (320), the drive wheel (320) drives the internal gear ring (322) to rotate slowly via the driven wheel (321). The rotation of the internal gear ring (322) synchronously drives the upper trigger plate (326) to rotate. Since the gear disc (323) has an inner groove (324), the gear disc (323) is stuck by one of the limiting blocks (325). When the trigger plate (326) gradually contacts the stuck limiting block (325), the trigger plate (326) squeezes the limiting block (325) out of the inner groove (324). At the same time, the blocking rod (329) on the trigger plate (326) is squeezed. Due to the connection structure between the blocking rod (329) and the air chamber (328) and the piston rod (314), The connection structure of the blocking rod (329) and the regulating chamber (311) is the same, so that when the blocking rod (329) is squeezed by the limiting block (325), it retracts inward, so that the moving plate (318) at the bottom of the blocking rod (329) moves out of the limiting groove (317), and when the trigger plate (326) leaves the limiting block (325), it is released by the spring and reset from the W-shaped groove (316) to the V-shaped groove. At this time, the blocking rod (329) produces a backward pulling action, and the rear end of the blocking rod (329) pulls the movable sleeve (331) down through the push rod, so that the spring telescopic rod (332) enters the retracted state. With the downward movement of the spring telescopic rod (332), the push rod (333) above it moves down and drives the threaded sleeve (32) to rotate in the opposite direction. S3. With the reverse rotation of the threaded sleeve (32), the threaded sleeve (32) drives the first triangular plate (33) to rotate. Through the setting of the pulling rod (34) and the positioning rod (36), the cleaning plate (35) is driven to retract inward. When the cleaning plate (35) is stored in the receiving box (31), the cleaning plate (35) will squeeze the movable door (39) and retract in the inner wall of the release groove (38). The backward movement of the movable door (39) generates air pressure to push the piston rod (314) in the fixed rod (310) forward. Due to the connection structure of the blocking rod (329) and the air chamber (328) Similar to the connection structure of the piston rod (314) and the regulating chamber (311), as described in step S2, the moving plate (318) at the bottom of the piston rod (314) enters the V-groove (315) from the W-shaped groove (316). At this time, the piston rod (314) moves backward and resets, which reduces the pressure in the air chamber (313) and transmits the pressure in the sealing chamber (3125) to the air chamber (313). After the airflow passes through the pneumatic motor (3124), it pushes the unfolded guide plate (3123) to rotate counterclockwise and enter the arc-shaped groove (3122). S4. Simultaneously triggered by the trigger plate (326) and the limiting block (325), when the gear plate (323) rotates, the gear plate (323) synchronously drives the rotating plate (41). When the rotating plate (41) rotates once, the L-shaped rod located on the rotating plate (41) gradually moves from the inner annular groove (42) towards the guide block (43) and squeezes the guide block (43) to shield the annular groove (42) of the outer teeth, so that the L-shaped rod can move into the outer annular groove (42). At the same time, the front of the L-shaped rod... The movement causes the sliding sleeve (45) to move synchronously. Moving forward pushes the threaded rod (46) to rotate. The threaded rod (46) drives the external gear ring (410) to rotate through the gear column (49). The external gear ring (410) then synchronously drives several other sets of gear columns (49) to rotate. The rotation of the gear column (49) can drive the baffle plate (48) to open, so that the material is in a falling state at this time. At the same time, the cleaning plate (35) and the guide plate (3123) are in the reset and retracted state, which will not affect the normal use of the equipment. S5. Finally, when the trigger plate (326) triggers the limit block (325) again, the blocking rod (329) on the trigger plate (326) will push the movable sleeve (331) to drive the spring telescopic rod (332) to extend vertically, thereby causing the push rod (333) to move upward and push the threaded sleeve (32) to drive the first triangular plate (33) to rotate, so that several cleaning plates (35) squeeze the movable door (39) to open and unfold. At the same time, the opening of the movable door (39) squeezes the piston rod (314), and the piston rod (314) moves forward, generating air pressure to push the high-pressure airflow through the pneumatic motor (3124), pushing the guide plate (3123) to rotate clockwise, open, and divert the airflow for cleaning operation.
