Description

TECHNICAL FIELD

[0001] The present application relates to the field of phosphogypsum processing, in particular to an equipment and method for forming self-insulation blocks from phosphogypsum regeneration treatment. BACKGROUND

[0002] Phosphogypsum can be used as a green building material product for sustainable development after purification treatment. Light gypsum partition board, gypsum block, gypsum self-insulation block, waterproof gypsum block and other building products can be produced from phosphogypsum materials, which are usually used in wall insulation, light partition and prefabricated buildings. The production process of self-insulation blocks includes several steps such as upper mold, injection of material, vibration and exhaust, shaping, demolding, cutting and packaging. The cutting step directly affects the waste rate of the final product self-insulation block. In actual production, the green brick is cut into small blocks after being cut horizontally and vertically after being poured into the mold and then stacked and packaged.

[0003] A self-insulation block production line is disclosed in the related art with the publication number CN105799037A, which is composed of a mixing device, a green block device, a cutting device, an anti-slip drying device and a brick holder arranged in sequence on a track. A conveying device is also provided for transporting materials along the track. The raw materials for preparing self-insulation blocks are mixed in the mixing device and then injected into the green block device for foaming and forming into green bricks. The green bricks are transported to the cutting device for cutting, and then transferred out of the production line by the brick holder after passing through the anti-slip drying device.

[0004] In the related art, the green brick is cut into multiple long plates after being poured into the mold and then transferred by 90 degrees, and the plates are laid flat on the conveying line. In this process, the position of the plate will be offset to a certain extent due to the transmission error of the conveying line. The thickness of the green brick has been limited after the first cutting, which will cause the cut blocks at the edge of the plate to not meet the size requirements after the second cutting, resulting in waste. SUMMARY

[0005] To improve the problem of waste caused by the offset of the plate after turning over, the present application provides an equipment and method for forming self-insulation blocks from phosphogypsum regeneration treatment.

[0006] The first aspect of the present application provides an equipment for forming self-insulation blocks from phosphogypsum regeneration treatment, which adopts the following technical solution:

[0007] The application relates to an equipment for forming self-insulation building blocks by regenerating phosphogypsum, which comprises a mixing device, a block making device, a cutting device, a brick holding machine and a conveying device, wherein the cutting device comprises a first cutting device and a second cutting device, a first conveying belt arranged at the discharging end of the first cutting device and a second conveying belt arranged at the feeding end of the second cutting device, the first conveying belt is arranged in a direction perpendicular to the conveying direction of the second conveying belt, one end of the first conveying belt is provided with a rack, and the rack is provided with a pushing mechanism for pushing the brick slab on the first conveying belt to the second conveying belt and a turnover rack for overturning the brick slab on the first conveying belt to a flat state.

[0008] The rack is provided with a vertical correction mechanism for pushing the brick slab on the turnover rack to lift and drop when the turnover rack is overturned, and a horizontal correction mechanism for centrally holding the brick slab on the turnover rack.

[0009] By adopting the above technical scheme, the brick slab is cut into multiple brick slabs in the first cutting device, and then is conveyed to the rack by the first conveying belt; the pushing mechanism on the rack pushes the single brick slab to the turnover rack in sequence; the turnover rack overturns the brick slab on it to be horizontally laid on the second conveying belt; in the process, the vertical correction mechanism pushes the brick slab on the turnover rack to lift and drop, which can effectively avoid the situation that the lower edge of the brick slab does not completely rely on the short side of the turnover rack, and can make the lower edge of the brick slab closely adhere to the short side of the turnover rack to correct the uniformity of the brick slab in the width direction; then the horizontal correction mechanism centrally holds the brick slab, which can correct the uniformity of the brick slab in the length direction, and finally makes each brick slab overturned by the turnover rack to the second conveying belt keep in the set correction position, so as to as far as possible ensure that no edge and corner materials or waste materials are generated when the brick slab is cut by the second cutting device, and ensure the processing quality of the self-insulation building block.

[0010] Optionally, the turnover rack comprises a turnover shaft rotatably arranged on the rack and multiple right-angle turnover plates fixed to the turnover shaft.

[0011] The rack is provided with a damping mechanism for buffering when the turnover rack is overturned towards the second conveying belt, and is provided with a reset mechanism for driving the turnover rack to overturn towards the first conveying belt.

[0012] By adopting the technical scheme, after the pushing mechanism pushes the brick slab to the turnover frame, the brick slab drives the right-angle turnover plate and the turnover shaft to rotate on the rack under the action of its own weight, and in this process, the damping mechanism slows down the turnover of the turnover frame on the rack, which can effectively reduce the impact energy between the turned brick slab and the second conveying belt, and ensure the integrity and orientation consistency of the turned brick slab.

[0013] Optionally, the vertical correction mechanism comprises a right-angle correction plate arranged in parallel with the right-angle turnover plate, and a guide assembly is fixed to the turnover shaft to guide the long side of the right-angle correction plate;

[0014] The rack is provided with a power assembly for pushing the right-angle correction plate to slide back and forth along the long side direction of the right-angle correction plate when the turnover shaft is turned towards the second conveying belt.

[0015] By adopting the technical scheme, in the process of the brick slab being supported on the right-angle turnover plate and being turned with the right-angle turnover plate, the power assembly pushes the right-angle correction plate to lift up and drop down along the long side direction, which can lift up and then drop down the brick slab on the right-angle turnover plate, so that the two right-angle surfaces on the lower side of the brick slab are more closely attached to the short side and the long side of the right-angle turnover plate, thereby improving the consistency of the position of the brick slab when it is parked on the second conveying belt after being turned by the turnover frame, and improving the positioning accuracy of the brick slab in the turning process. In this process, the guide assembly guides the sliding track of the right-angle correction plate to reduce the influence of the right-angle correction plate on the position of the brick slab.

[0016] Optionally, the power assembly comprises a power shaft rotatably arranged on the rack and parallel to the turnover shaft, and the power shaft is in transmission connection with the turnover shaft.

[0017] The power shaft is fixed with a lever on the arc side, and the short side of the right-angle correction plate is fixed with a ball convex, and the ball convex is located within the swing range of the lever.

[0018] By adopting the technical scheme, when the turnover frame is turned, the power shaft in transmission connection with the turnover shaft is rotated, and the lever on the power shaft is turned when the power shaft is rotated, and the lever first pushes the ball convex to move away from the power shaft and then the lever moves away from the ball convex, so that the ball convex first pushes the right-angle correction plate to move up, and then the right-angle correction plate moves down under the weight of the brick slab, thereby achieving the effect of lifting up and then dropping down the brick slab on the turnover frame.

[0019] Optionally, the transverse correction mechanism comprises two sliding sleeves arranged on the frame and sleeved on the axial two ends of the turnover shaft respectively, clamping plates are mounted on the sliding sleeves, and a same-motion structure is arranged between the end of the turnover shaft and the sliding sleeve for driving the two sliding sleeves to move close to each other when the turnover shaft rotates towards the second conveying belt.

[0020] By adopting the above technical scheme, when the brick board is turned over by the turnover frame, the turnover shaft drives the two sliding sleeves to move close to each other under the action of the same-motion structure, and then the two clamping plates move close to each other, so that the two clamping plates can be centered and clamped in the length direction of the brick board to realize accurate positioning, and the position consistency of each brick board after being turned over by the turnover frame in the length direction of the brick board is ensured, so as to ensure the yield rate of the second cutting device.

[0021] Optionally, the same-motion structure comprises a sliding convexity fixed on the inner wall of the sliding sleeve and a helical groove opened on the circumferential side of the end of the turnover shaft, the sliding convexity is slidably matched with the helical groove, the two helical grooves at the two ends of the turnover shaft have the same pitch and opposite rotation directions, and a rotation-preventing assembly for preventing the rotation of the sliding sleeve is arranged on the frame.

[0022] By adopting the above technical scheme, when the brick board is turned over by the turnover frame, the turnover shaft rotates towards the second conveying belt, the sliding sleeve can only move along the axial direction of the turnover shaft under the driving action of the sliding convexity and the helical groove on the turnover shaft and the rotation-preventing limiting action of the rotation-preventing assembly, and then the two sliding sleeves move close to or away from each other synchronously when the turnover shaft is turned over, so that the two clamping plates can be centered and clamped on the brick board when the turnover frame is turned over towards the second conveying belt, and the two clamping plates can be reset away from each other when the turnover frame is turned over towards the first conveying belt to prepare for the centering and correction of the next brick board.

[0023] Optionally, the rotation-preventing assembly comprises a plurality of guide rods arranged in the axial direction of the turnover shaft, and the guide rods are arranged on the circumferential side of the turnover shaft and penetrate the sliding sleeve.

[0024] By adopting the above technical scheme, when the turnover shaft rotates, the sliding convexity on the inner side of the sliding sleeve slides in the helical groove on the turnover shaft, and the guide rods penetrate the sliding sleeve, so that the sliding sleeve can only move along the axial direction of the turnover shaft, and the stability of the sliding sleeve during movement is improved.

[0025] Optionally, a gap-reducing elastic member is arranged between the sliding sleeve and the frame, and the gap-reducing elastic member is in a compressed state when the two sliding sleeves move close to each other to the minimum distance.

[0026] By adopting the technical scheme, the gap reducing elastic member is always in a compressed state during the sliding of the sliding sleeve on the turnover shaft, so that the sliding convex and the helical groove are always in an abutting state, thereby effectively eliminating the displacement deviation caused by the gap between the sliding convex and the helical groove when the sliding sleeve slides on the turnover shaft, and improving the centering accuracy of the two clamping plates to the brick plate.

[0027] Optionally, the sliding sleeve is provided with an adjusting mechanism for adjusting the axial position of the clamping plate along the turnover shaft.

[0028] By adopting the technical scheme, when processing building blocks of different sizes, the shortest distance between the two clamping plates when they approach each other can be adjusted by the adjusting mechanism to adapt to different cutting requirements.

[0029] The second aspect of the present application provides a method for forming self-insulation building blocks by phosphogypsum regeneration treatment, which adopts the following technical scheme:

The turnover frame is rotated by the driving shaft connected in transmission with the turnover shaft during the turning over process, the driving shaft drives the push rod thereon to rotate during the rotation, the push rod drives the ball convex to move away from the driving shaft first and then the push rod moves away from the ball convex during the rotation, so that the ball convex drives the right-angle correction plate to move up first and then moves down with the right-angle correction plate under the weight of the brick plate, thereby achieving the effect of lifting up first and then falling down of the brick plate on the turnover frame.

[0050] The following will be described in detail with reference to the accompanying Figures 1-4 The present application is further described in detail.

[0051] The present application discloses an equipment for forming self-insulation building blocks by phosphogypsum regeneration treatment. Referring to Figure 1 , the equipment for forming self-insulation building blocks by phosphogypsum regeneration treatment comprises, in sequence, a mixing device, a block making device, a cutting device, a brick holding machine and conveying devices arranged between the units, the cutting device comprises a first cutting device 11 and a second cutting device 12, a first conveying belt 13 arranged at the discharge port end of the first cutting device 11 and a second conveying belt 14 arranged at the feeding port end of the second cutting device 12, and the first cutting device 11 and the second cutting device 12 can be a disc saw cutting machine, a ring saw belt cutting machine, a reciprocating saw, etc. The transmission directions of the first conveying belt 13 and the second conveying belt 14 are arranged orthogonally, one end of the first conveying belt 13 close to the second conveying belt 14 is provided with a rack 15, the rack 15 is located at the corner of the first conveying belt 13 and the second conveying belt 14, the rack 15 is provided with a pushing mechanism 16 for pushing the brick plate on the first conveying belt 13 to the second conveying belt 14 and an overturning frame 2 for overturning the brick plate on the first conveying belt 13 to a flat state; specifically, the pushing mechanism 16 is arranged as a 90-degree corner conveyor installed on the rack 15.

[0052] And, referring to Figure 1 and Figure 2The rack 15 is provided with a vertical correction mechanism for pushing the brick plate on the turnover frame 2 to lift and drop when the turnover frame 2 is turned over, and a horizontal correction mechanism for holding the brick plate on the turnover frame 2 in the middle. The turnover frame 2 comprises a turnover shaft 21 rotatably installed on the rack 15 and a plurality of right-angle turnover plates 22 fixed on the turnover shaft 21. The rack 15 is provided with a damping mechanism for buffering the turnover frame 2 when it is turned over towards the second conveying belt 14. The rack 15 is provided with a reset mechanism for driving the turnover frame 2 to turn over towards the first conveying belt 13. In actual arrangement, the damping mechanism and the reset mechanism are combined to form a servo motor for driving the turnover shaft 21 to rotate. A reduction box is arranged between the output end of the servo motor and the turnover shaft 21.

[0053] In this way, after the green bricks are cut into a plurality of brick plates by the first cutting device 11, the brick plates are conveyed to the rack 15 by the first conveying belt 13. The pushing mechanism 16 on the rack 15 pushes the single brick plates to the turnover frame 2 in sequence. Under the action of the self-weight of the brick plate, the right-angle turnover plate 22 and the turnover shaft 21 rotate on the rack 15, and the brick plate on the turnover shaft 21 is turned over to be horizontally laid on the second conveying belt 14. In this process, the damping mechanism slows down the turnover speed of the turnover frame 2 on the rack 15, which can effectively reduce the impact energy between the turned-over brick plate and the second conveying belt 14, and ensure the integrity and orientation consistency of the turned-over brick plate. In the process of turning over the turnover frame 2, the vertical correction mechanism pushes the brick plate on the turnover frame 2 to lift and drop, which can effectively avoid the situation that the lower edge of the brick plate does not completely rely on the short side of the turnover frame 2, so that the lower edge of the brick plate is tightly attached to the short side of the turnover frame 2 to correct the uniformity of the brick plate in the width direction. Then, the horizontal correction mechanism holds the brick plate in the middle, which can correct the uniformity of the brick plate in the length direction, and finally each brick plate turned over by the turnover frame 2 to the second conveying belt 14 can be kept at the set correction position, so as to ensure that there is no edge material or waste when the brick plate is cut by the second cutting device 12, and the processing quality of the self-insulation building block is ensured.

[0054] In specific arrangement, referring to Figure 2 and Figure 3 , the vertical correction mechanism comprises a right-angle correction plate 31 arranged in parallel with the right-angle turnover plate 22. A guide assembly is fixed on the turnover shaft 21 and guides the long side of the right-angle correction plate 31. The guide assembly comprises a guide rail 35 fixed on the turnover shaft 21 and arranged along the long side of the right-angle turnover plate 22, and a guide strip 36 fixed on the back of the right-angle correction plate 31 and slidingly matched with the guide rail 35.

[0055] The rack 15 is provided with a power assembly for pushing the right-angle correction plate 31 to slide back and forth along the long edge direction when the turnover shaft 21 is turned towards the second conveying belt 14; the power assembly comprises a power shaft 32 which is arranged on the rack 15 and parallel to the turnover shaft 21, and the power shaft 32 is in transmission connection with the turnover shaft 21, which can be chain transmission or belt transmission; the power shaft 32 is fixedly connected with a push rod 33 on the arc surface side, and the short edge bottom surface of the right-angle correction plate 31 is fixedly connected with a ball convex 34 which is located in the swing range of the push rod 33.

[0056] In this way, in the process of the brick board being supported on the right-angle turnover plate 22 and following the right-angle turnover plate 22 to turn, the turnover shaft 21 drives the power shaft 32 in transmission connection to rotate, the power shaft 32 drives the push rod 33 on it to turn when rotating, the push rod 33 first pushes the ball convex 34 to move away from the power shaft 32 and then the push rod 33 passes the ball convex 34, so as to make the ball convex 34 first push the right-angle correction plate 31 to drive the brick board to move upwards and then follow the right-angle correction plate 31 to move downwards under the gravity of the brick board, which can lift and then put down the brick board on the right-angle turnover plate 22, so as to make the two right-angle surfaces on the lower side of the brick board fit the short edge and the long edge of the right-angle turnover plate 22 more closely, and then improve the consistency of the position of the brick board when it is parked on the second conveying belt 14 after being turned by the turnover frame 2, and improve the positioning accuracy of the brick board in the turning process. In this process, the guide assembly guides the sliding track of the right-angle correction plate 31 to reduce the influence of the right-angle correction plate 31 on the position of the brick board.

[0057] In actual setting, one right-angle correction plate 31 and a corresponding power assembly can be arranged on the turnover shaft 21, or multiple right-angle correction plates 31 and multiple corresponding power assemblies can be arranged, and the difference is only the stability of the right-angle correction plate 31 when it pushes the brick board to turn.

[0058] If multiple right-angle correction plates 31 and multiple corresponding power assemblies are selected to be arranged, in other feasible embodiments, a time difference can be set between the pushing actions of different power assemblies to the right-angle correction plate 31, that is, the multiple right-angle correction plates 31 are lifted and lowered at different times, and in particular, the two right-angle correction plates 31 at the two ends of the turnover shaft 21 are lifted at different times when the turnover shaft 21 is turned, so as to form the left and right swinging of the brick board on the turnover frame 2, thereby maximizing the fitting effect of the brick board on the short edge and the long edge of the turnover frame 2. In order to achieve this effect, only the installation position and actual length of different push rods 33 on the power shaft 32 need to be changed, such as Figure 2 the installation positions of the two push rods 33 shown.

[0059] On the other hand, referring to Figure 3 and Figure 4The transverse correction mechanism comprises two sliding sleeves 41 which are slidingly arranged on the frame 15 and sleeved on the two axial ends of the turnover shaft 21 respectively, the clamping plates 42 are arranged on the sliding sleeves 41, and the same-motion structure for driving the two sliding sleeves 41 to approach each other when the turnover shaft 21 rotates towards the second conveying belt 14 is arranged between the end of the turnover shaft 21 and the sliding sleeve 41. The same-motion structure comprises a sliding convex 43 fixed on the inner wall of the sliding sleeve 41 and a helical groove 44 formed in the circumferential side of the end of the turnover shaft 21, the sliding convex 43 is slidingly matched with the helical groove 44, and the two helical grooves 44 at the two ends of the turnover shaft 21 have the same pitch and opposite rotation directions. Meanwhile, the anti-rotation assembly for preventing the rotation of the sliding sleeve 41 is arranged on the frame 15. The anti-rotation assembly comprises a plurality of guide rods 45 arranged in the axial direction of the turnover shaft 21, and the guide rods 45 are arranged on the circumferential side of the turnover shaft 21 and penetrate through the sliding sleeve 41.

[0060] In this way, when the brick board is turned with the turnover frame 2, the turnover shaft 21 rotates towards the second conveying belt 14, the sliding sleeve 41 can only move in the axial direction of the turnover shaft 21 under the driving action of the sliding convex 43 on the sliding sleeve 41 and the helical groove 44 on the turnover shaft 21 and the limiting and guiding action of the guide rods 45 on the sliding sleeve 41, and then the synchronous approaching or moving away of the two sliding sleeves 41 during the turning of the turnover shaft 21 is realized, so that the two clamping plates 42 can centrally hold the brick board in the length direction when the turnover frame 2 is turned towards the second conveying belt 14 to realize accurate positioning, and the position consistency of each brick board after being turned by the turnover frame 2 in the length direction of the brick board is ensured to ensure the yield rate of the second cutting device 12. When the turnover frame 2 is turned towards the first conveying belt 13, the two clamping plates 42 are away from each other and reset to prepare for the central correction of the next brick board.

[0061] However, considering that the sliding convex 43 and the helical groove 44 will have a certain gap when the sliding sleeve 41 slides by matching the sliding convex 43 and the helical groove 44, the gap will be further enlarged on the clamping plate 42 installed away from the sliding sleeve 41, which will cause a large error when the two clamping plates 42 hold the brick board on the turnover frame 2. Therefore, referring to Figure 3 and Figure 4 a gap-reducing elastic member 46 is arranged between the sliding sleeve 41 and the frame 15, the gap-reducing elastic member 46 is arranged as a spring sleeved on the guide rod 45, and the two gap-reducing elastic members 46 are arranged on the sides away from each other of the two sliding sleeves 41; when the two sliding sleeves 41 approach to the minimum distance, the gap-reducing elastic members 46 are still in the compressed state.

[0062] In this way, the gap-reducing elastic member 46 is always in the compressed state during the sliding of the sliding sleeve 41 on the turnover shaft 21, so that the sliding convex 43 and the helical groove 44 are always in the abutting state, thereby effectively eliminating the displacement deviation of the sliding sleeve 41 caused by the gap between the sliding convex 43 and the helical groove 44 when the sliding sleeve 41 slides on the turnover shaft 21, and improving the central accuracy of the two clamping plates 42 to the brick board.

[0063] To make this application applicable to the production needs of blocks of different sizes, the sliding sleeve 41 is provided with an adjustment mechanism for adjusting the axial position of the clamping plate 42 along the flipping shaft 21. Specifically, refer to... Figure 2 and Figure 3 A support arm 47, inclined upwards and pointing towards the second conveyor belt 14, is fixedly connected to the outer peripheral wall of the arc surface of the sliding sleeve 41. A clamping plate 42 is located on the side of the support arm 47 closer to the second conveyor belt 14, and a sliding rod 48 is fixed on the support arm 47, passing through the free end of the support arm 47. The adjusting mechanism includes an adjusting screw 49 threaded through the support arm 47 and rotatably connected to the clamping plate 42. Therefore, by rotating the adjusting screw 49, the distance between the clamping plate 42 and the support arm 47 can be changed, thereby changing the distance between the two clamping plates 42, to suit the centering and clamping of bricks of different sizes.

[0064] The implementation principle of the equipment for forming self-insulating blocks by phosphogypsum recycling in this application embodiment is as follows: After the brick blank is cut into multiple brick slabs in the first cutting device 11, it is transported to the frame 15 by the first conveyor belt 13. The pushing mechanism 16 on the frame 15 pushes the single brick slabs to the flipping frame 2 in sequence. Under the action of its own weight, the brick slab drives the right-angle flipping plate 22 and the flipping shaft 21 to rotate on the frame 15, and flips the brick slabs on it to be laid horizontally on the second conveyor belt 14. During this process, the damping mechanism slows down the flipping speed of the flipping frame 2 on the frame 15, which can effectively reduce the impact energy between the flipped brick slabs and the second conveyor belt 14, and ensure the integrity and orientation consistency of the flipped brick slabs.

[0065] Furthermore, during the flipping process of the flipping frame 2, the vertical correction mechanism pushes the bricks on the flipping frame 2 to rise and fall, which can effectively avoid the situation where the lower edge of the brick is not completely against the short side of the flipping frame 2. This ensures that the lower edge of the brick is tightly attached to the short side of the flipping frame 2, thereby correcting the uniformity of the brick in the width direction. Then, the horizontal correction mechanism centers and hugs the brick, which can correct the uniformity of the brick in the length direction. Finally, each brick flipped by the flipping frame 2 onto the second conveyor belt 14 can be kept in the set correction position, so as to ensure that no scraps or waste are generated when the bricks are cut by the second cutting device 12, thus ensuring the processing quality of the self-insulating blocks.

[0066] This application also discloses a method for forming self-insulating blocks through phosphogypsum recycling. The method includes the following steps:

[0067] S1. Mixing: Inject the recycled phosphogypsum mixture into the mixing device and stir until uniform;

[0068] S2. Forming: The evenly mixed phosphogypsum mixture is fed into the forming device and cured.

[0069] S3. demolding, after the brick embryo is formed in the embryo forming device, demolding is performed;

[0070] S4. cutting, the demolded brick embryo is transferred to the first cutting device 11 to be cut into multiple brick boards in the longitudinal direction;

[0071] S5. cutting, after the brick boards obtained in step S4 are flipped to the flat laying state by the flipping frame 2, the brick boards are corrected by the vertical correction mechanism to the degree of adhesion to the flipping frame 2, then are centered and corrected by the horizontal correction mechanism, and finally are sequentially and neatly conveyed to the second cutting device 12 by the second conveying belt 14 to be cut into finished building blocks;

[0072] S6. packing, the finished building blocks are stacked and placed by the brick holder, and then are packed.
