Description

Technical Field

[0001] The present invention belongs to the technical field of steam curing preparation of cement fiber boards, and particularly relates to a device and a preparation method for preparing composite reinforced cement fiber boards. Background Art

[0002] Cement fiber exterior wall hanging boards are a new type of green building energy-saving material and are widely used in the exterior wall facades of buildings. As exterior wall hanging boards, higher requirements are placed on the wind pressure resistance performance of the boards. Therefore, the delivered boards must meet the requirements. The strength of cement products is determined by the degree of hydration reaction of cement. The longer the reaction time, the higher the strength. Therefore, after the wet blanks of general cement exterior wall hanging boards are made, they can only be delivered after natural curing for 28 days, which greatly affects the production and delivery process.

[0003] Currently, some factories promote the hydration reaction of cement through the method of high-temperature steam curing in an autoclave, which greatly shortens the delivery date and improves production efficiency. However, due to the imperfect steam curing equipment, the condensed water generated by the steam equipment will drip onto the boards, which will cause surface defects or uneven curing of the boards.

One end of the siphon pipe I away from the elbow I penetrates through the bottom of the water storage box and is fixedly connected with a siphon pipe II through an elbow II. The siphon pipe II and the elbow II are located inside the water storage box.

[0012] As a preference of the above technical solution, a connecting member is fixedly sleeved on the outer circle of the pipe body. A heat preservation outer shell is fixedly sleeved on the outer circle of the connecting member. One end of the heat preservation outer shell close to the reaction box is in a horn shape.

[0013] As a preference of the above technical solution, a moving groove is formed in the side of the reaction box away from the water storage box, and a sliding port communicating with the moving groove is formed in the inner wall.

A material guiding pad fixedly installed on the inner bottom wall of the reaction box is arranged below the sealing box. One side of the material guiding pad close to the partition cover is lower than the side away from the partition cover.

[0015] The preparation method of the composite reinforced cement fiber board preparation device includes the following steps:

[0016] S1. Preparation of the cement fiber board;

[0017] After the cement fiber board is processed and formed, it is placed on the steam curing rack, the furnace door of the steam curing furnace is opened and it is pushed into it, and high-temperature steam curing preparation is carried out on the cement fiber board through the side steam pipe and the upper steam pipe;

[0018] S2. Collect condensed water;

[0019] The steam transported by the pipe body will form condensed water and adhere to the inner wall after encountering cold. Since the pipe body is vertically arranged, the condensed water will slide into the inside of the water storage box for collection;

[0020] S3. Discharge condensed water;

[0021] When the condensed water inside the water storage box overflows the second elbow pipe, a siphon effect will occur, and the condensed water will be discharged into the inside of the reaction box;

[0022] S4. Heat condensed water;

[0023] After the condensed water enters the inside of the reaction box, the buoyancy of the air bag can push the moving cover and the funnel cover to rise. The calcium oxide in the cavity formed by the sealing box, the moving cover and the funnel cover will slide down through the feeding port into the condensed water, and react with the condensed water to heat it;

[0024] S5. Insulation of the pipe body;

[0025] The reaction of calcium oxide with condensed water will generate 700 degrees Celsius. The evaporated water vapor will enter the channel between the heat preservation shell and the pipe body to insulate the pipe body, so that the pipe body can quickly heat up and avoid continuous generation of condensed water on the inner wall;

[0026] S6. Calcium oxide filling;

[0027] During the process of the moving cover driving the support plate to rise, the partition cover will be pushed to rise together through the push plate. At this time, the condensed water and calcium oxide will slide from the guide pad to above the air inlet hole. At this time, the water level line will drop, and the moving cover and the funnel cover will drop together. When the third guide hole, the second guide hole and the first guide hole are on the same axis, the second elastic member will push the pressing plate to squeeze the calcium oxide located inside the storage cylinder into the cavity formed by the sealing box, the moving cover and the funnel cover.

[0028] The beneficial effects of the present invention are:

[0029] 1. After the cement fiber board is processed and formed, it is placed on a steaming rack, the door of the steaming furnace is opened and pushed into the steaming furnace, and the cement fiber board is subjected to high-temperature steaming preparation through the side steam pipe and the upper steam pipe. Calcium oxide is arranged in the cavity formed by the sealing box, the movable cover and the funnel cover, and the siphon mechanism discharges the condensed water in the water storage box into the reaction box through the siphon effect, and the movable cover and the funnel cover are pushed up by the buoyancy of the airbag, and the calcium oxide is discharged into the reaction box to react with water. The generated water vapor can keep the pipe body warm, reduce the probability of condensed water generation, avoid defects on the surface of the board, and improve the uniformity of curing;

[0030] 2. According to the present invention, when the movable cover and the funnel cover are pushed upward, the calcium oxide inside will fall into the interior of the reaction box from the discharge port, and at the same time, the material guide hole three will be staggered with the material guide hole two. When the movable cover and the funnel cover fall to their original positions, the material guide hole three will be realigned with the material guide hole two and the material guide hole one. At this time, the calcium oxide inside the storage barrel will be poured into the cavity formed by the sealing box, the movable cover and the funnel cover. When the situation of condensed water continuing to appear in the tube body cannot be improved, it is convenient to repeatedly heat the collected condensed water. BRIEF DESCRIPTION OF THE DRAWINGS

The feeding mechanism 45 includes a sealing box 451. The sealing box 451 is installed inside the reaction box 421 through a material storage mechanism 44. A moving cover 452 and a funnel cover 453 are respectively movably sleeved on the outer circle and the inner circle of the sealing box 451. The moving cover 452 is fixedly connected with the funnel cover 453. An air bag 455 is provided below the sealing box 451. The air bag 455 is fixedly connected with the funnel cover 453 through a piston rod 454. The piston rod 454 is piston-connected with the sealing box 451. A connecting piece 412 is fixedly sleeved on the outer circle of the pipe body 413. A heat preservation outer shell 411 is fixedly sleeved on the outer circle of the connecting piece 412. One end of the heat preservation outer shell 411 close to the reaction box 421 is in a horn shape.

[0042] Specifically, after the cement fiber board is processed and formed, it is placed on the steam curing rack 30. The furnace door of the steam curing furnace 10 is opened and pushed into it. The cement fiber board is prepared by high-temperature steam curing through the side steam pipe 20 and the upper steam pipe 40. Calcium oxide is provided in the cavity formed by the sealing box 451, the moving cover 452 and the funnel cover 453. The siphon mechanism 43 drains the condensed water in the water storage box 414 into the reaction box 421 through the siphon effect. The buoyancy of the air bag 455 pushes the moving cover 452 and the funnel cover 453 to rise, and the calcium oxide is drained into the reaction box 421 to react with water. The generated water vapor can keep the pipe body 413 warm and reduce the probability of condensed water generation. Embodiment

[0043] Such as Figure 3 、 Figure 4 and Figure 6As shown, for the composite reinforced cement fiber board preparation device, compared with Embodiment 1, the stock storage mechanism 44 in this embodiment includes a stock storage cylinder 441. One end of the stock storage cylinder 441 is fixed on the bottom inner wall of the reaction box 421, and the other end is threadedly connected with a sealing cover 443. An installation plate 447 is fixedly sleeved on the outer circle of the stock storage cylinder 441. The sealing box 451 is movably sleeved on the outer circle of the stock storage cylinder 441 and is clamped with the installation plate 447. A sealing member 444 is fixedly connected to one side of the sealing cover 443 close to the stock storage cylinder 441. The sealing member 444 is made of, but not limited to, rubber. The sealing member 444 is located inside the stock storage cylinder 441. One side of the sealing member 444 is fixedly connected with a pressing plate 446 through an elastic member II 445. The elastic member II 445 is made of, but not limited to, a spring. A tapered block 442 fixed in the inner wall of the stock storage cylinder 441 is arranged on the side of the pressing plate 446 away from the elastic member II 445. Calcium oxide is provided between the tapered block 442 and the pressing plate 446.

[0044] Specifically, the stock storage cylinder 441 is threadedly connected with the sealing cover 443, making it convenient to disassemble and assemble. When there is no calcium oxide left in the cavity of the stock storage cylinder 441, it can be opened for perfusion, or the sealing box 451 can be removed from the stock storage cylinder 441. By providing the sealing member 444, it can prevent condensed water from seeping into the stock storage cylinder 441 from the gap between the stock storage cylinder 441 and the sealing cover 443, maintaining the sealing performance of the stock storage cylinder 441 and avoiding reaction with the internal calcium oxide. At the same time, the acting force of the elastic member II 445 will push the pressing plate 446 to move towards the side of the tapered block 442, and the pressing plate 446 will push the calcium oxide to collapse towards the side away from the axis of the stock storage cylinder 441 through the cooperation of the tapered block 442. Embodiment

[0045] Such as Figure 3 、 Figure 4 、 Figure 5 And Figure 7As shown, for the preparation device of the composite reinforced cement fiber board proposed by the present invention, compared with Embodiment 1 or Embodiment 2, in this embodiment, a moving groove is provided on the side of the reaction box 421 away from the water storage box 414, and a sliding opening communicating with the moving groove is provided on the inner wall. A partition cover 423 is slidably installed in the moving groove, and the length of the moving groove is greater than the length of the partition cover 423, so that the partition cover 423 can completely enter the moving groove. The bottom of the partition cover 423 is attached to the inner bottom wall of the reaction box 421, dividing the reaction box 421 into two parts. The condensed water in the water storage box 414 first flows into the cavity on the side close to the storage cylinder 441. An elastic member 425 is fixedly connected to the top. The elastic member 425 is not limited to using a spring. The top end of the elastic member 425 is fixedly connected to the moving groove. A push plate 424 fixedly connected to the partition cover 423 is slidably connected to the sliding opening. A support plate 457 cooperating with the push plate 424 is fixedly connected to the outer wall of the moving cover 452. A magnetic attraction member is provided between the sealing box 451 and the moving cover 452. The magnetic attraction member includes a magnetic positive pole and a magnetic negative pole, which are respectively fixed on the sealing box 451 and the moving cover 452 and attract each other magnetically.

[0046] Specifically, after the siphon mechanism 43 pumps the condensed water located inside the water storage box 414 into the inside of the reaction box 421, the buoyancy of the airbag 455 is used to push the moving cover 452 and the funnel cover 453 to rise, and the calcium oxide is discharged into the reaction box 421 to react with water. When the moving cover 452 rises, it will drive the support plate 457 to rise together. The support plate 457 will lift the partition cover 423 into the moving groove through the push plate 424. At this time, the condensed water and calcium oxide will enter the side of the partition cover 423 away from the storage cylinder 441. When the water level drops, the moving cover 452 and the funnel cover 453 will also fall, and finally the moving cover 452 and the sealing box 451 are completely closed through the magnetic attraction member.

[0047] As Figure 4 、 Figure 5 and Figure 7 shown, a guiding groove 426 is provided on the side of the reaction box 421 away from the water storage box 414, and an air inlet hole 427 and an air outlet hole 428 communicating with the guiding groove 426 are provided on the inner wall of the reaction box 421. The air inlet hole 427 and the air outlet hole 428 are respectively located on both sides of the partition cover 423. A guiding pad 422 fixedly installed on the inner bottom wall of the reaction box 421 is provided below the sealing box 451. The side of the guiding pad 422 close to the partition cover 423 is lower than the side away from the partition cover 423, which is convenient for guiding the condensed water and calcium oxide on the side of the storage cylinder 441 to the side of the partition cover 423 away from the storage cylinder 441.

[0048] Specifically, condensed water and calcium oxide are introduced into the side of the partition cover 423 away from the storage barrel 441, and after the partition cover 423 falls back, the heat and water vapor generated by the condensed water and calcium oxide will enter the interior of the guide groove 426 from the air inlet 427, and then be discharged from the exhaust hole 428 to between the insulation shell 411 and the tube body 413 to keep the tube body 413 warm.

[0049] like Figure 6 As shown, a material guide hole 1 441a is provided on the side wall of the material storage barrel 441 near the conical block 442, a material guide hole 2 451a matching therewith is provided on the side of the sealing box 451 near the material guide hole 1 441a, a material guide hole 3 453a matching therewith is provided on the side of the funnel cover 453 near the material guide hole 2 451a, the diameters of the material guide hole 3 453a, the material guide hole 2 451a and the material guide hole 1 441a are the same, a material discharge port 452a is provided on the side of the movable cover 452 near the side wall of the sealing box 451, and the material discharge port 452a is fixedly connected to an inclined waterproof plate 456.

[0050] Specifically, when the movable cover 452 and the funnel cover 453 are pushed upward, the calcium oxide inside will fall into the interior of the reaction box 421 from the discharge port 452a, and at the same time, the material guide hole three 453a will also be staggered with the material guide hole two 451a. When the movable cover 452 and the funnel cover 453 fall to their original positions, the material guide hole three 453a will be realigned with the material guide hole two 451a and the material guide hole one 441a. At this time, the calcium oxide located inside the storage barrel 441 will be poured into the cavity formed by the sealing box 451, the movable cover 452 and the funnel cover 453. When the situation of condensed water continuing to appear in the tube body 413 cannot be improved, it is convenient to repeatedly heat the collected condensed water. Example

[0051] like Figure 4 and Figure 7 As shown, the composite reinforced cement fiber board preparation device proposed in the present invention, compared with Example 1 or Example 2 or Example 3, the siphon mechanism 43 of this embodiment includes a bellows 431, the bellows 431 is detachably connected to the reaction box 421, the reaction box 421 is provided with a pipe hole 421a, the bellows 431 is inserted therein, the end of the bellows 431 away from the reaction box 421 is fixedly connected to a siphon tube 433 through a bend 432, the end of the siphon tube 433 away from the bend 432 passes through the bottom of the water storage box 414, and is fixedly connected to a siphon tube 435 through a bend 434, and the siphon tube 435 and the bend 434 are located inside the water storage box 414.

[0052] Specifically, the lengths of the siphon tube II 435 and the elbow tube II 434 are less than the depth of the water storage box 414. When the condensed water collected in the water storage box 414 is lower than the elbow tube II 434, the condensed water will accumulate inside the water storage box 414. When the condensed water overflows the elbow tube II 434, the condensed water will be pumped into the reaction box 421 through the siphon effect until the water level line of the condensed water inside the water storage box 414 is lower than the end of the siphon tube II 435 far from the elbow tube II 434.

[0053] The preparation method of the composite reinforced cement fiber board preparation device includes the following steps:

[0054] S1. Preparation of the cement fiber board;

[0055] After the cement fiber board is processed and formed, it is placed on the steam curing rack 30, the furnace door of the steam curing furnace 10 is opened and it is pushed into it, and the cement fiber board is prepared by high-temperature steam curing through the side steam pipe 20 and the upper steam pipe 40;

[0056] S2. Collection of condensed water;

[0057] The steam transported by the pipe body 413 will form condensed water and adhere to the inner wall after being cooled. Since the pipe body 413 is vertically arranged, the condensed water will slide into the water storage box 414 for collection;

[0058] S3. Discharge of condensed water;

[0059] When the condensed water inside the water storage box 414 overflows the elbow tube II 434, a siphon effect will be generated to discharge the condensed water into the reaction box 421;

[0060] S4. Heating of condensed water;

[0061] After the condensed water enters the reaction box 421, the buoyancy of the air bag 455 can push the moving cover 452 and the funnel cover 453 to rise. The calcium oxide in the cavity formed by the sealing box 451, the moving cover 452 and the funnel cover 453 will slide into the condensed water through the material outlet 452a to react with the condensed water for heating;

[0062] S5. Heat preservation of the pipe body 413;

[0063] The reaction of calcium oxide with condensed water will generate 700 degrees Celsius. The evaporated water vapor will enter the channel between the heat preservation outer shell 411 and the pipe body 413 to heat-preserve the pipe body 413, enabling the pipe body 413 to quickly heat up and preventing continuous generation of condensed water on the inner wall;

[0064] S6. Filling of calcium oxide;

[0065] During the process of the moving cover 452 driving the supporting plate 457 to rise, the separating cover 423 will be pushed to rise together by the push plate 424. At this time, the condensed water and calcium oxide will slide from the material guiding pad 422 to above the air inlet hole 427. At this time, the water level line will drop, and the moving cover 452 and the funnel cover 453 will drop together. When the third material guiding hole 453a, the second material guiding hole 451a, and the first material guiding hole 441a are on the same axis, the second elastic member 445 will push the pressing plate 446 to squeeze the calcium oxide located inside the storage cylinder 441 into the cavity formed by the sealing box 451, the moving cover 452, and the funnel cover 453.

5. The preparation method of the composite reinforced cement fiber board preparation device according to claim 4, characterized in that, It includes the following steps: S1. Preparation of cement fiber board; After the cement fiber board is processed and formed, it is placed on the steam curing rack (30). The furnace door of the steam curing furnace (10) is opened and it is pushed into it. The cement fiber board is prepared by high-temperature steam curing through the side steam pipe (20) and the upper steam pipe (40). S2. Collection of condensed water; The steam transported by the pipe body (413) will form condensed water and adhere to the inner wall after being cooled. Since the pipe body (413) is vertically arranged, the condensed water will slide down into the interior of the water storage box (414) for collection. S3. Discharge of condensed water; When the condensed water inside the water storage box (414) overflows the elbow pipe II (434), a siphon effect will occur, and the condensed water will be discharged into the interior of the reaction box (421). S4. Heating of condensed water; After the condensed water enters the interior of the reaction box (421), the buoyancy of the airbag (455) can push the moving cover (452) and the funnel cover (453) to rise. The calcium oxide in the cavity formed by the sealing box (451), the moving cover (452) and the funnel cover (453) will slide down into the condensed water through the blanking port (452a) to react with the condensed water for heating. S5. Heat preservation of the pipe body (413); The reaction of calcium oxide with condensed water will generate 700 degrees Celsius. The evaporated water vapor will enter the channel between the heat preservation outer shell (411) and the pipe body (413) to insulate the pipe body (413), so that the pipe body (413) can be quickly heated up and avoid continuous generation of condensed water on the inner wall. S6. Filling of calcium oxide; During the process of the moving cover (452) driving the pallet (457) to rise, the partition cover (423) will be pushed to rise together through the push plate (424). At this time, the condensed water and calcium oxide will slide from the guide pad (422) to above the air inlet hole (427). At this time, the water level line will drop, and the moving cover (452) and the funnel cover (453) will drop together. When the third material guide hole (453a), the second material guide hole (451a), and the first material guide hole (441a) are on the same axis, the second elastic member (445) will push the pressing plate (446) to squeeze the calcium oxide inside the storage cylinder (441) into the cavity formed by the sealing box (451), the moving cover (452), and the funnel cover (453).
