Description

Technical Field

[0001] This utility model relates to the field of building material production technology, specifically to a maintenance device applied to 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 in a specific ratio to form a homogeneous powder. This mixture is then poured into a mold and pressed into shape using mechanical pressure. The resulting phosphogypsum hollow blocks have a low initial hardness. Subsequently, a hydration reaction occurs, producing dihydrate phosphogypsum and releasing a significant amount of heat. As the hydration reaction progresses, the hardness of the phosphogypsum hollow blocks gradually increases until they reach a certain strength to meet the requirements of subsequent handling and construction. However, the process of increasing the hardness of the phosphogypsum hollow blocks through hydration is time-consuming, leading to a decrease in overall production efficiency. Furthermore, the heat released during the hydration reaction is largely wasted as most of it is lost to the surrounding environment. Utility Model Content

[0004] This invention aims to provide a maintenance device for phosphogypsum hollow blocks, which can effectively shorten the time required for the hydration reaction to increase the hardness of the blocks, thereby improving overall production efficiency and avoiding the waste of heat energy released by the hydration reaction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] 1) A curing device for phosphogypsum hollow blocks, comprising a support, a conveying mechanism on the support, a long strip-shaped curing cover above the conveying mechanism along its axial direction, an air outlet and an air inlet at both ends of the upper side of the curing cover, an air extraction mechanism above the curing cover, the two ends of the air extraction mechanism being connected to the air outlet and the air inlet respectively, and a spraying mechanism inside the curing cover, the spraying mechanism being located between the air outlet and the air inlet.

[0007] 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.

[0008] 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.

[0009] The air extraction mechanism collects the heat energy released by the hydration reaction inside the curing hood through the air outlet and discharges the collected hot air into the end of the curing hood through the air inlet, providing heat energy for the freshly pressed phosphogypsum hollow blocks. This accelerates the hydration reaction, shortens the hardening time of the phosphogypsum hollow blocks, and at the same time, reduces energy waste and improves overall production efficiency through heat energy circulation.

[0010] The spraying system is used to spray water mist onto the surface of phosphogypsum hollow blocks, keeping them moist and ensuring the hydration reaction proceeds fully. The uniform distribution of the water mist prevents the blocks from drying out or experiencing uneven hardening, further improving the hardening quality and production efficiency. Furthermore, the spraying system can also be used to spray waterproofing agents and other additives onto the surface of the phosphogypsum hollow blocks, enhancing their waterproof performance or other specific functions, depending on production needs.

[0011] 2) The maintenance device for phosphogypsum hollow blocks as described in 1), wherein:

[0012] 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.

[0013] 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.

[0014] 3) The curing device for phosphogypsum hollow blocks as described in 1), wherein:

[0015] The gas extraction mechanism includes a U-shaped gas pipe with its two ends connected to an outlet and an inlet, respectively. A fan is installed inside the gas pipe, with the fan positioned close to the inlet and its outlet facing the inlet.

[0016] In this invention, a servo motor is mounted on the outer surface of the gas pipe, and the rotating shaft of the exhaust fan is connected to the output shaft of the servo motor via a belt. After the servo motor is started, its output shaft begins to rotate, driving the rotating shaft of the exhaust fan to rotate via belt drive, which in turn drives the impeller inside the exhaust fan to rotate. The rotation of the impeller inside the exhaust fan generates negative pressure inside the gas pipe, thereby drawing the hot gas from the curing hood into the gas pipe through the outlet. The drawn-in hot gas flows along the gas pipe towards the exhaust fan.

[0017] As hot gas flows through the exhaust fan, the rotation of the impeller inside the fan further increases the flow rate of the hot gas and propels it towards the air inlet. Subsequently, the hot gas enters the curing hood through the air inlet and provides heat energy to the freshly pressed phosphogypsum hollow blocks, thereby accelerating their hydration reaction and improving the efficiency of the hydration reaction.

[0018] 4) The maintenance device for phosphogypsum hollow blocks as described in 1), wherein:

[0019] 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.

[0020] 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 hydration reaction proceeds smoothly. 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 blocks' waterproofing or other specific functions.

[0021] 5) The curing device for phosphogypsum hollow blocks as described in 4), wherein:

[0022] Vertical plates are connected to both ends of the spray pipe. The vertical plates have circular through holes. Several vertical rods corresponding to the vertical plates are provided inside the curing hood. The vertical rods are set on the upper surface of the support and located on both sides of the conveyor belt inside the curing hood. The vertical rods have strip-shaped through holes along their axial direction. Bolts are inserted into the circular through holes and the strip-shaped through holes. Nuts are threaded onto the bolts.

[0023] In this invention, vertical plates are located on both sides of the spray pipe, used to connect the spray pipe to the vertical rod. A fixed connection between the vertical rod and the vertical plates is achieved by simultaneously passing bolts through both the circular and strip-shaped through holes and tightening the nuts. By loosening the nuts, the vertical plates can move up and down along the strip-shaped through hole of the vertical rod, thereby adjusting the height of the spray pipe. After adjusting to a suitable height, the nuts are tightened to fix the position of the vertical plates on the vertical rod. This allows the height of the spray pipe to be flexibly adjusted according to the height of the phosphogypsum hollow blocks, ensuring that the atomizing nozzles can spray evenly onto the block surface, thus improving the adaptability and working efficiency of the spraying mechanism.

[0024] Compared with the prior art, the present invention also has the following technical effects:

[0025] This invention provides a suitable curing environment for phosphogypsum hollow blocks by installing a curing hood above the conveying mechanism. This effectively maintains the temperature and humidity of the phosphogypsum hollow blocks, ensuring the smooth progress of the hydration reaction. Compared with the prior art, this invention adds an air extraction mechanism above the curing hood, which collects the heat released by the hydration reaction inside the curing hood and discharges it back into the end of the curing hood, providing heat energy for the freshly pressed phosphogypsum hollow blocks.

[0026] This design not only accelerates the hydration reaction and shortens the hardening time of phosphogypsum hollow blocks, but also reduces energy waste through heat circulation, significantly improving overall production efficiency. Furthermore, the curing hood is equipped with a spraying mechanism that sprays water mist onto the surface of the phosphogypsum hollow blocks, keeping them moist and ensuring a thorough hydration reaction, further enhancing the hardening quality and production efficiency of the phosphogypsum hollow blocks. Attached Figure Description

[0027] Figure 1 This is a schematic diagram of the structure of the maintenance device of this utility model applied to phosphogypsum hollow blocks.

[0028] Figure 2 This is a side view of the spraying mechanism in the maintenance device of the present invention applied to phosphogypsum hollow blocks. Detailed Implementation

[0029] The following detailed description illustrates the specific implementation method:

[0030] The reference numerals in the accompanying drawings include: bracket 1, curing cover 2, air outlet 3, air inlet 4, drive wheel 5, driven wheel 6, conveyor belt 7, rotating shaft 8, drive motor 9, gas pipe 10, exhaust fan 11, spray pipe 12, atomizing nozzle 13, water pipe 14, water tank 15, suction pump 16, vertical plate 17, vertical rod 18, strip-shaped through hole 19, and servo motor 20.

[0031] See the example. Figure 1 and Figure 2 As shown, the maintenance device for phosphogypsum hollow blocks in this embodiment includes a support 1, a conveying mechanism on the support 1, a long strip-shaped curing cover 2 covering the conveying mechanism along its axial direction, an air outlet 3 and an air inlet 4 at both ends of the upper side of the curing cover 2, an air extraction mechanism above the curing cover 2, the two ends of the air extraction mechanism being connected to the air outlet 3 and the air inlet 4 respectively, and a spraying mechanism inside the curing cover 2, the spraying mechanism being located between the air outlet 3 and the air inlet 4.

[0032] 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.

[0033] 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.

[0034] The air extraction mechanism collects the heat energy released by the hydration reaction inside the curing hood 2 through the air outlet 3, and discharges the collected hot air into the end of the curing hood 2 through the air inlet 4, providing heat energy for the newly pressed phosphogypsum hollow blocks, thereby accelerating the hydration reaction and shortening the hardening time of the phosphogypsum hollow blocks. At the same time, the heat energy circulation reduces energy waste and improves the overall production efficiency.

[0035] The spraying system is used to spray water mist onto the surface of phosphogypsum hollow blocks, keeping them moist and ensuring the hydration reaction proceeds fully. The uniform distribution of the water mist prevents the blocks from drying out or experiencing uneven hardening, further improving the hardening quality and production efficiency. Furthermore, the spraying system can also be used to spray waterproofing agents and other additives onto the surface of the phosphogypsum hollow blocks, enhancing their waterproof performance or other specific functions, depending on production needs.

[0036] The conveying mechanism includes a driving wheel 5 and a driven wheel 6, with a conveyor belt 7 wound between them. A rotating shaft 8 is coaxially mounted inside the driving wheel 5, and a drive motor 9 is connected to the end of the rotating shaft 8. In this embodiment, the output shaft of the drive motor 9 is directly connected to the rotating shaft 8. After the drive motor 9 is started, its output shaft begins to rotate, thereby driving the rotating shaft 8 to rotate. Since the rotating shaft 8 is coaxially mounted with the driving wheel 5, the rotation of the rotating shaft 8 drives the driving wheel 5 to rotate.

[0037] The conveyor belt 7 is wound between the driving wheel 5 and the driven wheel 6. The rotation of the driving wheel 5 drives the conveyor belt 7 to run around the driving wheel 5 and the driven wheel 6 through friction. The running of the conveyor belt 7 can drive the driven wheel 6 to rotate, thereby realizing the continuous operation of the conveyor belt 7.

[0038] The gas extraction mechanism includes a U-shaped gas pipe 10, with its two ends connected to an outlet 3 and an inlet 4, respectively. A blower 11 is installed inside the gas pipe 10, and the blower 11 is located close to the inlet 4, with the outlet of the blower 11 facing the inlet 4.

[0039] In this embodiment, a servo motor 20 is mounted on the outer surface of the gas pipe 10, and the rotating shaft of the exhaust fan 11 is connected to the output shaft of the servo motor 20 via a belt. After the servo motor 20 is started, its output shaft begins to rotate, driving the rotating shaft of the exhaust fan 11 to rotate via belt drive, thereby driving the impeller inside the exhaust fan 11 to rotate. The rotation of the impeller inside the exhaust fan generates a negative pressure inside the gas pipe 10, thereby drawing the hot gas inside the curing hood 2 into the gas pipe 10 through the air outlet 3. The drawn-in hot gas flows along the gas pipe 10 and towards the exhaust fan 11.

[0040] When hot gas flows through the exhaust fan 11, the rotation of the impeller inside the exhaust fan 11 further increases the flow rate of the hot gas and pushes the hot gas toward the air inlet 4. Subsequently, the hot gas enters the curing hood 2 through the air inlet 4 and provides heat energy to the newly pressed phosphogypsum hollow blocks, thereby accelerating their hydration reaction and improving the hydration reaction efficiency.

[0041] The spraying mechanism includes a spray pipe 12 fixed inside the curing cover. Both ends of the spray pipe 12 are closed. Several atomizing nozzles 13 are evenly distributed along the axial direction of the spray pipe 12 and face the conveyor belt surface. A water pipe 14 is connected to the end of the side wall of the spray pipe 12. The other end of the water pipe 14 is connected to a water tank 15. A suction pump 16 is connected to the water pipe 14.

[0042] In this embodiment, the suction pump 16 is activated to draw water from the water tank 15 and transport it to the water pipe 14. The water is then transported through the water pipe 14 to the spray pipe 12. The water in the spray pipe 12 is atomized into fine droplets by the atomizing nozzle 13 and evenly sprayed onto the surface of the phosphogypsum hollow blocks, keeping the blocks moist and ensuring the smooth progress of the hydration reaction. Furthermore, functional additives such as waterproofing agents can be added to the water tank 15 according to production needs. These additives are sprayed onto the surface of the phosphogypsum hollow blocks through the atomizing nozzle 13, thereby increasing the blocks' waterproofing or other specific functions.

[0043] Vertical plates 17 are connected to both ends of the spray pipe 12. The vertical plates 17 have circular through holes. Several vertical rods 18 corresponding to the vertical plates 17 are provided inside the curing cover 2. The vertical rods 18 are set on the upper surface of the support 1 and located on both sides of the conveyor belt 7 inside the curing cover 2. The vertical rods 18 have strip-shaped through holes 19 along their axial direction. Bolts are inserted into the circular through holes and the strip-shaped through holes 19. The bolts are threaded with nuts.

[0044] In this embodiment, vertical plates 17 are located on both sides of the spray pipe 12 and are used to connect the spray pipe 12 and the vertical rod 18. A fixed connection between the vertical rod 18 and the vertical plate 17 is achieved by simultaneously passing bolts through the circular through hole and the strip-shaped through hole 19 and tightening the nuts. By loosening the nuts, the vertical plate 17 can move up and down along the strip-shaped through hole 19 of the vertical rod 18, thereby adjusting the height of the spray pipe 12. After adjusting to a suitable height, the nuts are tightened to fix the position of the vertical plate 17 on the vertical rod 18, so that the height of the spray pipe 12 can be flexibly adjusted according to the height of the phosphogypsum hollow block, ensuring that the atomizing nozzle 13 can spray evenly onto the block surface, thereby improving the adaptability and working efficiency of the spraying mechanism.

[0045] This embodiment provides a suitable curing environment for the phosphogypsum hollow blocks by setting 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. Compared with the prior art, this embodiment adds an air extraction mechanism above the curing cover 2, which can collect the heat energy released by the hydration reaction inside the curing cover 2 and discharge it back into the end of the curing cover 2, providing heat energy for the freshly pressed phosphogypsum hollow blocks.

[0046] This design not only accelerates the hydration reaction and shortens the hardening time of phosphogypsum hollow blocks, but also reduces energy waste through heat circulation, significantly improving overall production efficiency. Furthermore, the curing cover 2 is equipped with a spraying mechanism that sprays water mist onto the surface of the phosphogypsum hollow blocks, keeping them moist and ensuring a thorough hydration reaction, further enhancing the hardening quality and production efficiency of the phosphogypsum hollow blocks.
