Description

Technical Field

[0001] This utility model relates to the technical field of building material production, and specifically to a cleaning device for the maintenance of phosphogypsum hollow blocks. Background Technology

[0002] Phospholipid gypsum hollow blocks are a new type of lightweight wall material with advantages such as environmental protection and energy saving, high strength, earthquake resistance, heat insulation, sound insulation, fire resistance, moisture resistance, and convenient use and installation. They are particularly suitable as interior wall partition materials for high-rise buildings and large-span buildings in urban and rural areas. They are a new type of wall material that the national housing and urban-rural construction sector has been vigorously developing and promoting for many years.

[0003] Phosphogypsum hollow blocks are typically produced using a mechanized casting process (commonly known as "wet production"). In this process, phosphogypsum powder, dihydrate phosphogypsum powder, a hydration regulator, and water are first mixed in a mixer according to a specific ratio to form a homogeneous powder. The homogeneous powder is then poured into a mold and pressed into shape using mechanical pressure. The pressed phosphogypsum hollow blocks have a low initial hardness and require a hydration reaction to gradually harden and increase their strength.

[0004] To promote a complete hydration reaction, pressed phosphogypsum hollow blocks are typically sprayed with water to ensure sufficient moisture on their surface and inside, allowing for a uniform and thorough hydration reaction. However, loose powder remains on the surface of the pressed phosphogypsum hollow blocks. This loose powder hinders direct contact between water and the block surface during spraying, preventing water from penetrating evenly into the block's interior. This results in uneven and incomplete hydration, ultimately affecting the production quality of the phosphogypsum hollow blocks. Utility Model Content

[0005] This utility model aims to provide a cleaning device for the maintenance of phosphogypsum hollow blocks, which can clean the surface of the pressed phosphogypsum hollow blocks, thereby ensuring that the spray water mist can directly contact the surface of the phosphogypsum hollow blocks and evenly penetrate into the interior during the subsequent spraying process, thus improving the production quality of phosphogypsum hollow blocks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] 1) A cleaning device for the maintenance of phosphogypsum hollow blocks, comprising a support frame, a conveying mechanism on the support frame, a long strip-shaped curing cover above the conveying mechanism along its axial direction, a rolling cleaning mechanism, a stationary cleaning mechanism and a spraying mechanism inside the curing cover, the rolling cleaning mechanism and the stationary cleaning mechanism being located at opposite ends of the curing cover, and the spraying mechanism being located between the rolling cleaning mechanism and the stationary cleaning mechanism.

[0008] In this invention, a conveying mechanism is used to transport the pressed phosphogypsum hollow blocks into a curing hood, and to move them within the curing hood to complete the curing process. The curing hood is positioned above the conveying mechanism, and its interior forms a semi-enclosed space with the upper surface of the conveying mechanism. This space provides a suitable curing environment for the phosphogypsum hollow blocks, effectively maintaining the temperature and humidity of the phosphogypsum hollow bricks and ensuring the smooth progress of the hydration reaction.

[0009] In the high temperatures of summer, the curing cover prevents direct contact between the phosphogypsum hollow blocks and the outside air, preventing moisture loss from the surface and interior of the blocks due to evaporation, thus ensuring the smooth progress of the hydration reaction. In the low temperatures of winter, the curing cover prevents cold air from contacting the phosphogypsum hollow blocks, maintaining their temperature and preventing low temperatures from affecting the efficiency of the hydration reaction, ensuring its full progress.

[0010] A rolling cleaning mechanism is located at the inlet of the curing hood and is used to clean the surface of the pressed phosphogypsum hollow blocks. After the phosphogypsum hollow blocks enter the curing hood via the conveyor, they first undergo cleaning by the rolling cleaning mechanism. Through high-speed rotation, the rolling cleaning mechanism quickly and thoroughly removes loose powder adhering to the surface of the phosphogypsum hollow blocks. This cleaning process ensures a clean surface for the phosphogypsum hollow blocks, thereby ensuring that the sprayed water mist can directly contact the surface of the phosphogypsum hollow blocks and penetrate evenly into their interior during subsequent spraying treatments.

[0011] After the rolling cleaning mechanism completes the cleaning, the phosphogypsum hollow blocks enter the spraying mechanism for spraying treatment. The spraying mechanism sprays water mist onto the surface of the phosphogypsum hollow blocks to keep them moist and ensure the hydration reaction proceeds fully. Since loose powder on the surface has been removed, the sprayed water mist can directly contact the surface of the phosphogypsum hollow blocks and penetrate evenly into the interior. The uniform distribution of the sprayed water mist avoids problems such as dryness or uneven hardening of the phosphogypsum hollow blocks, thus significantly improving the finishing quality. In addition, the spraying mechanism can also be used to spray waterproofing agents and other additives onto the surface of the phosphogypsum hollow blocks according to production needs, thereby enhancing the waterproof performance or other specific functions of the phosphogypsum hollow blocks.

[0012] During the spraying process, the sprayed water mist moistens the surface of the phosphogypsum hollow blocks, softening any unreacted powder on the surface. This causes the powder to detach from the surface of the phosphogypsum hollow blocks, forming a small amount of loose powder. To remove this loose powder, the sprayed phosphogypsum hollow blocks undergo a static cleaning process, effectively removing the loose powder formed on the surface after spraying. This ensures the cleanliness of the phosphogypsum hollow block surface and facilitates the smooth progress of subsequent processes.

[0013] 2) The cleaning device for the maintenance of phosphogypsum hollow blocks as described in 1), wherein:

[0014] The conveying mechanism includes a driving wheel and a driven wheel, with a conveyor belt wound between the driving wheel and the driven wheel. A rotating shaft is coaxially arranged inside the driving wheel, and a drive motor is connected to the end of the rotating shaft.

[0015] In this invention, the output shaft of the drive motor is directly connected to the rotating shaft. After the drive motor is started, its output shaft begins to rotate, which in turn drives the rotating shaft to rotate. Since the rotating shaft and the drive wheel are coaxially arranged, the rotation of the rotating shaft drives the drive wheel to rotate. The conveyor belt is wound between the drive wheel and the driven wheel, and the rotation of the drive wheel drives the conveyor belt to run around the drive wheel and the driven wheel through friction. The running of the conveyor belt drives the driven wheel to rotate, thereby achieving continuous operation of the conveyor belt.

[0016] 3) The cleaning device for the maintenance of phosphogypsum hollow blocks as described in 1), wherein:

[0017] The rolling cleaning mechanism includes a roller brush with bristles on its surface and a rolling shaft coaxially arranged inside the roller brush. A first fixing member and a second fixing member are rotatably connected to both ends of the rolling shaft. The first fixing member and the second fixing member are both arranged on the upper surface of the bracket and are located on both sides of the conveyor belt inside the curing cover. One end of the rolling shaft passes through the second fixing member and is connected to a servo motor. The servo motor is arranged on the side of the second fixing member.

[0018] In this invention, the first and second fixing members respectively support the two ends of the rolling shaft, ensuring the stability of the roller brush during rotation and preventing it from shifting during cleaning. A servo motor is mounted on the side of the second fixing member, and its output shaft is fixedly connected to one end of the rolling shaft. Upon starting the servo motor, its output shaft begins to rotate, thereby driving the rolling shaft to rotate. Because the rolling shaft and the roller brush are coaxial, the rotation of the rolling shaft directly drives the roller brush to rotate at high speed.

[0019] The bristles on the roller brush make direct contact with the surface of the phosphogypsum hollow blocks. The rotating motion of the roller brush efficiently cleans the surface of the phosphogypsum hollow blocks beneath the bristles. This rolling cleaning method quickly and thoroughly removes loose powder from the surface of the phosphogypsum hollow blocks, ensuring a clean surface. This, in turn, ensures that during subsequent spraying treatments, the sprayed water mist can directly contact the surface of the phosphogypsum hollow blocks and penetrate evenly into their interior.

[0020] 4) The cleaning device for the maintenance of phosphogypsum hollow blocks as described in 3), wherein:

[0021] The first fixing member includes a fan-shaped first rotating piece, which is in contact with the side of the bracket. The central end of the first rotating piece is rotatably connected to the side of the bracket, and the first rotating piece can rotate around its central end along the side surface of the bracket.

[0022] The first rotating plate has a first circular hole at its upper end. One end of the rolling shaft passes through the first circular hole, and the end of the rolling shaft passing through the first circular hole can rotate within the first circular hole. The first rotating plate has a first arc-shaped hole along its circumference. A first bolt passes through the first arc-shaped hole. The first bolt includes a head and a screw. The side of the head is fixedly connected to the edge of the upper surface of the bracket, and the other side is fixedly connected to the screw. The screw faces the bracket and extends outward through the first arc-shaped hole. A first nut is threadedly connected to the end of the screw away from the head.

[0023] In this embodiment, the first rotating plate is in contact with the side of the bracket, and the first rotating plate can rotate around its central end along the side of the bracket. One end of the rolling shaft passes through the first circular hole. Therefore, by rotating the first rotating plate, the height of the upper end of the first rotating plate exceeding the upper surface of the bracket can be adjusted, thereby adjusting the height of the rolling shaft. This allows it to adapt to phosphogypsum hollow blocks of various sizes, increasing its flexibility and applicability. The first rotating plate has a first arc-shaped hole along its circumference, and a first bolt passes through the first arc-shaped hole. The head of the first bolt is fixedly connected to the edge of the upper surface of the bracket, and the shank of the first bolt extends outward toward the bracket.

[0024] The first rotating plate has a first arc-shaped hole along its circumference, and the first bolt passes through the first arc-shaped hole. When the first rotating plate rotates, the first bolt moves within the first arc-shaped hole. As the first bolt moves within the first arc-shaped hole, the height of the upper end of the first rotating plate above the upper surface of the bracket changes, thereby adjusting the height of the rolling shaft. Once the height of the rolling shaft is adjusted to the appropriate position, the rotation of the first rotating plate stops.

[0025] Then, by tightening the first nut, the first bolt is fixed in the first arc-shaped hole, thereby fixing the first rotating plate and preventing it from shifting during operation. Since one end of the rolling shaft passes through the first circular hole of the first rotating plate, fixing the first rotating plate also ensures the stability of the rolling shaft's position, thus guaranteeing the stability of the cleaning process and the cleaning effect.

[0026] 5) The cleaning device for the maintenance of phosphogypsum hollow blocks as described in 3), wherein:

[0027] The second fixing member includes a fan-shaped second rotating plate, which is in contact with the side of the bracket. The central end of the second rotating plate is rotatably connected to the side of the bracket, and the second rotating plate can rotate around its central end along the side surface of the bracket.

[0028] The upper end of the second rotating plate is provided with a second circular hole. One end of the rolling shaft passes through the second circular hole, and the end of the rolling shaft passing through the second circular hole can rotate within the second circular hole. The second rotating plate is provided with a second arc-shaped hole along its circumference. A second bolt passes through the second arc-shaped hole. The second bolt includes a head and a screw. The side of the head is fixedly connected to the edge of the upper surface of the bracket, and the other side is fixedly connected to the screw. The screw faces the bracket and extends outward through the second arc-shaped hole. A second nut is threadedly connected to the end of the screw away from the head.

[0029] In this invention, the second rotating plate is fitted against the side of the bracket, and the second rotating plate can rotate around its central end along the side of the bracket. One end of the rolling shaft passes through the second circular hole. Therefore, by rotating the second rotating plate, the height of the upper end of the second rotating plate exceeding the upper surface of the bracket can be adjusted, thereby adjusting the height of the rolling shaft. This allows it to adapt to phosphogypsum hollow blocks of various sizes, increasing its flexibility and applicability. The second rotating plate has a second arc-shaped hole along its circumference, and a second bolt passes through the second arc-shaped hole. The head of the second bolt is fixedly connected to the edge of the upper surface of the bracket, and the screw of the second bolt extends outward from the bracket.

[0030] The second rotating plate has a second arc-shaped hole along its circumference, and the second bolt passes through this hole. When the second rotating plate rotates, the second bolt moves within the arc-shaped hole. As the second bolt moves within the arc-shaped hole, the height of the upper end of the second rotating plate above the upper surface of the bracket changes, thereby adjusting the height of the rolling shaft. Once the height of the rolling shaft is adjusted to the appropriate position, the rotation of the second rotating plate stops.

[0031] Then, by tightening the second nut, the second bolt is fixed in the second arc-shaped hole, thereby securing the second rotating plate and preventing it from shifting during operation. Since one end of the rolling shaft passes through the second circular hole of the second rotating plate, the fixing of the second rotating plate also ensures the stability of the rolling shaft's position, thus guaranteeing the stability of the cleaning process and the cleaning effect.

[0032] 6) The cleaning device for the maintenance of phosphogypsum hollow blocks according to 1), wherein:

[0033] The spraying mechanism includes a spray pipe fixed inside the curing hood. Both ends of the spray pipe are closed. Several atomizing nozzles are evenly distributed along the axial direction of the spray pipe and face the conveyor belt surface. A water pipe is connected to the end of the side wall of the spray pipe. A water tank is connected to the other end of the water pipe. A suction pump is connected to the water pipe.

[0034] This invention utilizes a suction pump to draw water from a tank and deliver it to a water pipe, which then transports the water to a spray pipe. The water in the spray pipe is atomized into fine droplets through atomizing nozzles and evenly sprayed onto the surface of the phosphogypsum hollow blocks, keeping them moist and ensuring the smooth progress of the hydration reaction. Furthermore, functional additives such as waterproofing agents can be added to the tank as needed. These additives are sprayed onto the surface of the phosphogypsum hollow blocks through the atomizing nozzles, thereby enhancing the waterproofing or other specific functions of the blocks.

[0035] 7) The cleaning device for the maintenance of phosphogypsum hollow blocks as described in 6), wherein:

[0036] The spray pipe is connected to two ends of a first vertical plate, and the first vertical plate has a first small round hole. The curing cover has several first vertical rods that correspond one-to-one with the first vertical plate. The first vertical rods are set on the upper surface of the support and located on both sides of the conveyor belt inside the curing cover. The first vertical rods have a first strip hole along their axial direction. The first small round hole and the first strip hole are fitted with first fixing bolts, and the first fixing bolts are threaded with first fixing nuts.

[0037] In this invention, the first vertical pieces are located on both sides of the spray pipe and are used to connect the spray pipe to the first vertical rod. The first vertical rod and the first vertical pieces are fixedly connected by passing the first fixing bolt through both the first small round hole and the first strip-shaped hole simultaneously and tightening the first fixing nut. By loosening the first fixing nut, the first vertical pieces can move up and down along the first strip-shaped hole, thereby adjusting the height of the spray pipe. Once the spray pipe is adjusted to a suitable height, the first fixing nut is tightened to fix the position of the first vertical pieces on the first vertical rod. This allows the height of the spray pipe to be flexibly adjusted according to the height of the phosphogypsum hollow block, ensuring that the atomizing nozzle can spray evenly onto the surface of the phosphogypsum hollow block, thereby improving the adaptability and working efficiency of the spraying mechanism.

[0038] 8) The cleaning device for the maintenance of phosphogypsum hollow blocks according to 1), wherein:

[0039] The stationary cleaning mechanism includes a brush with stiff bristles facing the conveyor belt. A second vertical plate is connected to each end of the brush. The second vertical plate has a second small round hole. Several second vertical rods, each corresponding to one of the second vertical plates, are located on the upper surface of the support and on both sides of the conveyor belt inside the curing cover. Each second vertical rod has a second strip-shaped hole along its axis. Second fixing bolts pass through the second small round hole and the second strip-shaped hole, and the second fixing bolts are threaded with a second fixing nut.

[0040] In this invention, the stiff bristles on the brush surface directly contact the surface of the phosphogypsum hollow block, cleaning the surface of the phosphogypsum hollow block as it moves beneath the bristles, thereby ensuring the cleanliness of the phosphogypsum hollow block surface and ensuring the smooth progress of subsequent processes. The second vertical plates are located on both sides of the brush and are used to connect the brush to the second vertical rod.

[0041] By passing the second fixing bolt through both the second small round hole and the second strip-shaped hole, and tightening the second fixing nut, the second vertical rod and the second vertical piece are fixedly connected. By loosening the second fixing nut, the second vertical piece can move up and down along the second strip-shaped hole, thereby adjusting the height of the brush. Once the brush is adjusted to the appropriate height, tightening the second fixing nut fixes the position of the second vertical piece on the second vertical rod. This allows the height of the brush to be flexibly adjusted according to the size of the phosphogypsum hollow block, thereby improving the adaptability and flexibility of the stationary cleaning mechanism.

[0042] Compared with the prior art, this utility model also has the following technical effects:

[0043] This invention provides a suitable curing environment for phosphogypsum hollow blocks by installing a curing cover above the conveying mechanism. This effectively maintains the temperature and humidity of the phosphogypsum hollow blocks, ensuring the smooth progress of the hydration reaction. The curing cover is equipped with a spraying mechanism that sprays water mist onto the surface of the phosphogypsum hollow blocks to keep them moist and ensure the hydration reaction proceeds fully.

[0044] Compared with existing technologies, this invention adds a rolling cleaning mechanism at the inlet of the curing hood to clean the surface of the pressed phosphogypsum hollow blocks. This ensures that during subsequent spraying, the sprayed water mist can directly contact the surface of the phosphogypsum hollow blocks and penetrate evenly into their interior, thus improving the production quality of the phosphogypsum hollow blocks. In addition, a stationary cleaning mechanism is also provided inside the curing hood to clean the powder from the surface of the phosphogypsum hollow blocks after spraying, ensuring the smooth progress of subsequent processes.

[0050] The following detailed description illustrates the specific implementation method:

[0051] The reference numerals in the accompanying drawings include: bracket 1, curing cover 2, drive wheel 3, driven wheel 4, conveyor belt 5, rotating shaft 6, drive motor 7, roller brush 8, rolling shaft 9, servo motor 10, first rotating plate 11, first round hole 12, first arc-shaped hole 13, first bolt 14, first nut 15, second rotating plate 16, second bolt 17, second nut 18, spray pipe 19, atomizing nozzle 20, water pipe 21, water tank 22, suction pump 23, first vertical plate 24, first vertical rod 25, first strip hole 26, first fixing bolt 27, first fixing nut 28, brush 29, second vertical plate 30, second vertical rod 31, second strip hole 32, second fixing bolt 33, second fixing nut 34.

[0052] See the example. Figure 1 As shown, the cleaning device for the maintenance of phosphogypsum hollow blocks in this embodiment includes a support 1, a conveying mechanism on the support 1, and a long strip-shaped curing cover 2 covering the conveying mechanism along its axial direction. The curing cover 2 is equipped with a rolling cleaning mechanism, a stationary cleaning mechanism and a spraying mechanism. The rolling cleaning mechanism and the stationary cleaning mechanism are located at both ends of the curing cover 2, and the spraying mechanism is located between the rolling cleaning mechanism and the stationary cleaning mechanism.

[0053] In this embodiment, the conveying mechanism is used to transport the pressed phosphogypsum hollow blocks into the curing hood 2 and move them within the curing hood 2 to complete the curing process. The curing hood 2 is positioned above the conveying mechanism, and its interior forms a semi-enclosed space with the upper surface of the conveying mechanism. This space provides a suitable curing environment for the phosphogypsum hollow blocks, effectively maintaining the temperature and humidity of the phosphogypsum hollow bricks and ensuring the smooth progress of the hydration reaction.

[0054] In the high-temperature environment of summer, the curing cover 2 can prevent direct contact between the phosphogypsum hollow blocks and the outside air, preventing the loss of moisture from the surface and interior of the phosphogypsum hollow blocks due to high-temperature evaporation, thereby ensuring the smooth progress of the hydration reaction. In the low-temperature environment of winter, the curing cover 2 can prevent the outside cold air from contacting the phosphogypsum hollow blocks, maintaining the temperature of the phosphogypsum hollow blocks, avoiding the impact of low temperature on the hydration reaction efficiency, and ensuring the full progress of the hydration reaction.

[0055] A rolling cleaning mechanism is located at the inlet end of the curing hood 2 to clean the surface of the pressed phosphogypsum hollow blocks. After the phosphogypsum hollow blocks enter the curing hood 2 via the conveyor mechanism, they first undergo cleaning by the rolling cleaning mechanism. Through high-speed rotation, the rolling cleaning mechanism quickly and thoroughly removes loose powder adhering to the surface of the phosphogypsum hollow blocks. This cleaning process ensures a clean surface for the phosphogypsum hollow blocks, thereby ensuring that during subsequent spraying treatment, the sprayed water mist can directly contact the surface of the phosphogypsum hollow blocks and penetrate evenly into their interior.

[0056] After the rolling cleaning mechanism completes the cleaning, the phosphogypsum hollow blocks enter the spraying mechanism for spraying treatment. The spraying mechanism sprays water mist onto the surface of the phosphogypsum hollow blocks to keep them moist and ensure the hydration reaction proceeds fully. Since loose powder on the surface has been removed, the sprayed water mist can directly contact the surface of the phosphogypsum hollow blocks and penetrate evenly into the interior. The uniform distribution of the sprayed water mist avoids problems such as dryness or uneven hardening of the phosphogypsum hollow blocks, thus significantly improving the finishing quality. In addition, the spraying mechanism can also be used to spray waterproofing agents and other additives onto the surface of the phosphogypsum hollow blocks according to production needs, thereby enhancing the waterproof performance or other specific functions of the phosphogypsum hollow blocks.

[0057] During the spraying process, the sprayed water mist moistens the surface of the phosphogypsum hollow blocks, softening any unreacted powder on the surface. This causes the powder to detach from the surface of the phosphogypsum hollow blocks, forming a small amount of loose powder. To remove this loose powder, the sprayed phosphogypsum hollow blocks undergo a static cleaning process, effectively removing the loose powder formed on the surface after spraying. This ensures the cleanliness of the phosphogypsum hollow block surface and facilitates the smooth progress of subsequent processes.

[0058] See Figure 5 As shown, the conveying mechanism includes a driving wheel 3 and a driven wheel 4, with a conveyor belt 5 wound between them. A rotating shaft 6 is coaxially mounted inside the driving wheel 3, and a drive motor 7 is connected to the end of the rotating shaft 6. In this embodiment, the output shaft of the drive motor 7 is directly connected to the rotating shaft 6. After the drive motor 7 is started, its output shaft begins to rotate, thereby driving the rotating shaft 6 to rotate.

[0059] Since the rotating shaft 6 is coaxially arranged with the driving wheel 3, the rotation of the rotating shaft 6 drives the driving wheel 3 to rotate. The conveyor belt 5 is wound between the driving wheel 3 and the driven wheel 4. The rotation of the driving wheel 3 drives the conveyor belt 5 to run around the driving wheel 3 and the driven wheel 4 through friction. The running of the conveyor belt 5 can drive the driven wheel 4 to rotate, thereby realizing the continuous operation of the conveyor belt 5.

[0060] The rolling cleaning mechanism includes a roller brush 8 with bristles on its surface. A rolling shaft 9 is coaxially arranged inside the roller brush 8. A first fixing member and a second fixing member are rotatably connected to both ends of the rolling shaft 9. The first fixing member and the second fixing member are both arranged on the upper surface of the bracket 1 and are located on both sides of the conveyor belt 5 inside the curing cover 2. One end of the rolling shaft 9 passes through the second fixing member and is connected to a servo motor 10. The servo motor 10 is arranged on the side of the second fixing member.

[0061] In this embodiment, the first and second fixing members respectively support the two ends of the rolling shaft 9, ensuring that the roller brush 8 remains stable during rotation and preventing it from shifting during cleaning. A servo motor 10 is disposed on the side of the second fixing member, and the output shaft of the servo motor 10 is fixedly connected to one end of the rolling shaft 9. After the servo motor 10 is started, its output shaft begins to rotate, thereby driving the rolling shaft 9 to rotate. Since the rolling shaft 9 and the roller brush 8 are coaxially arranged, the rotation of the rolling shaft 9 directly drives the roller brush 8 to rotate at high speed.

[0062] The bristles on the surface of the roller brush 8 are in direct contact with the surface of the phosphogypsum hollow block. Through the rotational motion of the roller brush, the surface of the phosphogypsum hollow block that runs under the bristles is efficiently cleaned. The rolling cleaning method of the roller brush 8 can quickly and thoroughly remove loose powder from the surface of the phosphogypsum hollow block, ensuring that the surface of the phosphogypsum hollow block is clean. This ensures that during the subsequent spraying process, the sprayed water mist can directly contact the surface of the phosphogypsum hollow block and penetrate evenly into its interior.

[0063] See Figure 2 As shown, the first fixing member includes a fan-shaped first rotating plate 11, which is attached to the side of the bracket 1. The central end of the first rotating plate 11 is rotatably connected to the side of the bracket 1, and the first rotating plate 11 can rotate around its central end along the side surface of the bracket 1. A first circular hole 12 is provided at the upper end of the first rotating plate 11, and one end of the rolling shaft 9 passes through the first circular hole 12, and the end of the rolling shaft 9 passing through the first circular hole 12 can rotate within the first circular hole 12.

[0064] The first rotating plate 11 has a first arc-shaped hole 13 along its circumference. A first bolt 14 is inserted into the first arc-shaped hole 13. The first bolt 14 includes a head and a screw. The side of the head is fixedly connected to the edge of the upper surface of the bracket 1, and the other side is fixedly connected to the screw. The screw faces the bracket 1 and extends outward through the first arc-shaped hole 13. A first nut 15 is threadedly connected to the end of the screw away from the head.

[0065] In this embodiment, the first rotating plate 11 is in contact with the side of the bracket 1, and the first rotating plate 11 can rotate around its central end along the side of the bracket 1. One end of the rolling shaft 9 passes through the first circular hole 12. Therefore, by rotating the first rotating plate 11, the height of the upper end of the first rotating plate 11 exceeding the upper surface of the bracket 1 can be adjusted, thereby adjusting the height of the rolling shaft 9, so that it can adapt to phosphogypsum hollow blocks of various sizes, increasing its flexibility and applicability. The first rotating plate 11 has a first arc-shaped hole 13 opened along its circumference, and a first bolt 14 passes through the first arc-shaped hole 13. The head side of the first bolt 14 is fixedly connected to the edge of the upper surface of the bracket 1, and the screw of the first bolt 14 extends outward toward the bracket 1.

[0066] Since the first rotating plate 11 has a first arc-shaped hole 13 along its circumference, the first bolt 14 passes through the first arc-shaped hole 13. When the first rotating plate 11 rotates, the first bolt 14 will move within the first arc-shaped hole 13. As the first bolt 14 moves within the first arc-shaped hole 13, the height of the upper end of the first rotating plate 11 above the upper surface of the bracket 1 changes, thereby driving the height adjustment of the rolling shaft 9.

[0067] Once the height of the rolling shaft 9 is adjusted to the appropriate position, the rotation of the first rotating plate 11 is stopped. Then, the first nut 15 is tightened, and the first bolt 14 is fixed within the first arc-shaped hole 13, thereby securing the first rotating plate 11 and preventing it from shifting during operation. Since one end of the rolling shaft 9 passes through the first circular hole 12 of the first rotating plate 11, the fixing of the first rotating plate 11 also ensures the stability of the rolling shaft 9, thus guaranteeing the stability of the cleaning process and the cleaning effect.

[0068] The second fixing member includes a fan-shaped second rotating plate 16, which is attached to the side of the bracket 1. The central end of the second rotating plate 16 is rotatably connected to the side of the bracket 1. The second rotating plate 16 can rotate around its central end along the side surface of the bracket 1. A second circular hole is provided at the upper end of the second rotating plate 16. One end of the rolling shaft 9 passes through the second circular hole, and the end of the rolling shaft 9 that passes through the second circular hole can rotate inside the second circular hole.

[0069] The second rotating plate 16 has a second arc-shaped hole along its circumference, and a second bolt 17 is inserted into the second arc-shaped hole. The second bolt 17 includes a head and a screw. The side of the head is fixedly connected to the edge of the upper surface of the bracket 1, and the other side is fixedly connected to the screw. The screw faces the bracket 1 and extends outward through the second arc-shaped hole. The end of the screw away from the head is threadedly connected to a second nut 18.

[0070] In this embodiment, the second rotating plate 16 is in contact with the side of the bracket 1, and the second rotating plate 16 can rotate around its central end along the side of the bracket 1. One end of the rolling shaft 9 passes through the second circular hole. Therefore, by rotating the second rotating plate 16, the height of the upper end of the second rotating plate 16 exceeding the upper surface of the bracket 1 can be adjusted, thereby adjusting the height of the rolling shaft 9, so that it can adapt to phosphogypsum hollow blocks of various sizes, increasing its flexibility and applicability. The second rotating plate 16 has a second arc-shaped hole along its circumference, and a second bolt 17 passes through the second arc-shaped hole. The head side of the second bolt 17 is fixedly connected to the edge of the upper surface of the bracket 1, and the screw of the second bolt 17 extends outward toward the bracket 1.

[0071] Because the second rotating plate 16 has a second arc-shaped hole along its circumference, the second bolt 17 passes through the second arc-shaped hole. When the second rotating plate 16 rotates, the second bolt 17 moves within the second arc-shaped hole. As the second bolt 17 moves within the second arc-shaped hole, the height of the upper end of the second rotating plate 16 above the upper surface of the bracket 1 changes, thereby causing the height of the rolling shaft 9 to be adjusted.

[0072] Once the height of the rolling shaft 9 is adjusted to the appropriate position, the rotation of the second rotating plate 16 is stopped. The second bolt 17 is then fixed inside the second arc-shaped hole by tightening the second nut 18, thereby securing the second rotating plate 16 and preventing it from shifting during operation. Since one end of the rolling shaft 9 passes through the second circular hole of the second rotating plate 16, the fixing of the second rotating plate 16 also ensures the stability of the rolling shaft 9, thus guaranteeing the stability of the cleaning process and the cleaning effect.

[0073] See Figure 3 As shown, the spraying mechanism includes a spray pipe 19 fixed inside the curing cover 2. Both ends of the spray pipe 19 are closed. Several atomizing nozzles 20 are evenly distributed along the axial direction of the spray pipe 19 and face the conveyor belt surface. A water pipe 21 is connected to the end of the side wall of the spray pipe 19. The other end of the water pipe 21 is connected to a water tank 22. A suction pump 23 is connected to the water pipe 21.

[0074] In this embodiment, the suction pump 23 is activated to extract water from the water tank 22 and transport it to the water pipe 21. The water is then transported through the water pipe 21 to the spray pipe 19. The water in the spray pipe 19 is atomized into fine droplets by the atomizing nozzle 20 and evenly sprayed onto the surface of the phosphogypsum hollow blocks, keeping them moist and ensuring the smooth progress of the hydration reaction. Furthermore, functional additives such as waterproofing agents can be added to the water tank 22 according to production needs. These additives are sprayed onto the surface of the phosphogypsum hollow blocks through the atomizing nozzle 20, thereby increasing the waterproofing or other specific functions of the phosphogypsum hollow blocks.

[0075] The spray pipe 19 is connected to two ends of a first vertical plate 24. The first vertical plate 24 has a first small round hole. The curing cover 2 has several first vertical rods 25 that correspond one-to-one with the first vertical plate 24. The first vertical rods 25 are set on the upper surface of the support 1 and located on both sides of the conveyor belt 5 inside the curing cover 2. The first vertical rod 25 has a first strip hole 26 along its axis. The first small round hole and the first strip hole 26 are fitted with first fixing bolts 27. The first fixing bolts 27 are threadedly connected to first fixing nuts 28.

[0076] In this embodiment, the first vertical piece 24 is located on both sides of the spray pipe 19 and is used to connect the spray pipe 19 and the first vertical rod 25. The first vertical rod 25 and the first vertical piece 24 are fixedly connected by passing the first fixing bolt 27 through the first small round hole and the first strip hole 26 at the same time and tightening the first fixing nut 28.

[0077] By loosening the first fixing nut 28, the first vertical piece 24 can move up and down along the first strip hole 26, thereby adjusting the height of the spray pipe 19. After the spray pipe 19 is adjusted to a suitable height, the first fixing nut 28 is tightened to fix the position of the first vertical piece 24 on the first vertical rod 25, so that the height of the spray pipe 19 can be flexibly adjusted according to the height of the phosphogypsum hollow block, ensuring that the atomizing nozzle 20 can spray evenly onto the surface of the phosphogypsum hollow block, thereby improving the adaptability and working efficiency of the spraying mechanism.

[0078] See Figure 4 As shown, the stationary cleaning mechanism includes a brush 29. The surface of the brush 29 is provided with stiff bristles facing the conveyor belt 5. The two ends of the brush 29 are respectively connected to a second vertical plate 30. The second vertical plate 30 has a second small round hole. The curing cover 2 is provided with several second vertical rods 31 that correspond one-to-one with the second vertical plate 30. The second vertical rods 31 are set on the upper surface of the bracket 1 and located on both sides of the conveyor belt 5 inside the curing cover 2. The second vertical rods 31 have a second strip hole 32 along their axial direction. The second small round hole and the second strip hole 32 are provided with a second fixing bolt 33. The second fixing bolt 33 is threadedly connected to a second fixing nut 34.

[0079] In this embodiment, the stiff bristles on the surface of the brush 29 directly contact the surface of the phosphogypsum hollow block, cleaning the surface of the phosphogypsum hollow block as it moves beneath the bristles, thereby ensuring the cleanliness of the phosphogypsum hollow block surface and ensuring the smooth progress of subsequent processes. The second vertical piece 30 is located on both sides of the brush 29 and is used to connect the brush 29 to the second vertical rod 31. The second vertical rod 31 and the second vertical piece 30 are fixedly connected by simultaneously passing the second fixing bolt 33 through the second small round hole and the second strip hole 32, and tightening the second fixing nut 34.

[0080] By loosening the second fixing nut 34, the second vertical piece 30 can move up and down along the second strip hole 32, thereby adjusting the height of the brush 29. After the brush 29 is adjusted to the appropriate height, the second fixing nut 34 is tightened to fix the position of the second vertical piece 30 on the second vertical rod 31, so that the height of the brush 29 can be flexibly adjusted according to the size of the phosphogypsum hollow block, thereby improving the adaptability and flexibility of the stationary cleaning mechanism.

[0081] This embodiment provides a suitable curing environment for the phosphogypsum hollow blocks by installing a curing cover 2 above the conveying mechanism. This effectively maintains the temperature and humidity of the phosphogypsum hollow blocks, ensuring the smooth progress of the hydration reaction. The curing cover 2 is equipped with a spraying mechanism that sprays water mist onto the surface of the phosphogypsum hollow blocks to keep them moist and ensure the hydration reaction proceeds fully.

[0082] Compared with existing technologies, this embodiment adds a rolling cleaning mechanism at the inlet end of the curing hood 2 to clean the surface of the pressed phosphogypsum hollow blocks. This ensures that during subsequent spraying, the sprayed water mist can directly contact the surface of the phosphogypsum hollow blocks and penetrate evenly into their interior, improving the production quality of the phosphogypsum hollow blocks. In addition, a stationary cleaning mechanism is also provided inside the curing hood 2 to clean the powder from the surface of the phosphogypsum hollow blocks after spraying, ensuring the smooth progress of subsequent processes.
