Description

Technical Field

[0001] The invention relates to the technical field of cement curing, in particular to a cement masonry curing device and method. Background Art

[0002] Cement masonry is formed by strong pressure. In the field of modern building materials, cement masonry has become a widely used building material due to its environmental protection, high strength and aesthetics. Cement masonry is relatively fragile after forming, so it needs to be maintained.

[0003] Cement masonry is formed by pressing, which is also known as "unfired bricks", meaning that they can be formed without high-temperature firing or complex chemical changes. Therefore, the traditional steam curing process is not applicable to this type of material. The high moisture content and physical properties of cement masonry determine that curing in a high-temperature steam environment may cause serious quality problems. Due to the high moisture content, if high-temperature steam curing is carried out under such conditions, the loss of moisture and the change in pressure will be very drastic, which may cause the bricks to burst.

[0004] Therefore, cement masonry can only be cured in a natural environment, and the cement masonry needs to be watered to retain moisture during the curing process. However, it is impossible to ensure that all surfaces of the cement masonry are moistened during watering, and excessive watering of the cement masonry will also affect its quality. Therefore, the present invention provides a cement masonry curing device and method. Summary of the invention

A control structure for controlling the rotation of the two valve plates is provided on the valve body, and the valve plates are driven to rotate by the control structure so that the two valve plates block the two ends of the ventilation port. When the fan is running, air can be introduced into the maintenance bin from the air guide port, and the air in the maintenance bin can be discharged from the other air guide port.

[0016] A cement masonry maintenance method, the specific operations are as follows:

[0017] S1. The hydraulic cylinder is used to push the bin cover to rotate downward, so that the bin cover is laid open, and the folding guide rail is unfolded, so that the track in the curing bin and the track on the ground are docked with the folding guide rail, so that the rail car drives the cement bricks and stones to be transferred into the curing bin, and then the hydraulic cylinder pushes the bin cover to rotate upward, so that both ends of the curing bin are closed, so that the cement bricks and stones are dried and cured in a confined space;

Finally, open the bin cover and export the cured cement bricks and stones.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The closed environment provided by the equipment helps to reduce the evaporation of moisture in cement masonry, thereby promoting hydration reaction, accelerating the hardening process, and improving the strength and quality of the final product;

[0023] (2) Through the humidification of the spray system and the adjustment of the ventilation valve and fan, the humidity in the curing chamber is controlled and the air is circulated, which not only ensures the moist curing of cement masonry, but also prevents the problems caused by excessive humidity. At the same time, the curing chamber can be used to cure cement masonry in a ventilated environment, so that the curing chamber can be ventilated after moisturizing curing, thereby improving the quality of the product;

[0024] (3) The design of the folding rails allows cement bricks and stones to be directly transported into the curing bin by rail cars after the curing bin is opened, without the need for additional handling equipment, thus saving space and costs.

[0025] (4) Under the air circulation inside the curing chamber, part of the water mist sprayed by the spray system is mixed in the air and increases the humidity as the air flows. When the cement bricks and masonry come into contact with the air, they will be attached by water vapor to achieve the purpose of humidification. The other part of the water mist is sprayed directly on the cement bricks and masonry to moisturize them. In this way, the moisture on the cement bricks and masonry is evenly distributed, avoiding the problem of too much or too little watering on the surface of the cement bricks and masonry. The design of the drainage system ensures that the excess moisture inside the curing chamber can be effectively discharged, avoiding the adverse effects of water accumulation and excessive humidity on the curing process.

[0038] See also Figure 3 A drainage system 4 is provided at the bottom of the curing bin 1, and the condensed water mist droplets in the curing bin 1 are discharged through the drainage system 4, and two side-by-side tracks 5 are installed on the drainage system 4, and the drainage system 4 includes three drainage grooves 41 installed at the bottom of the curing bin 1, and the two drainage grooves 41 are respectively distributed on the two side edges of the curing bin 1, and another drainage groove 41 is located between the two drainage grooves 41, and two inclined panels 42 are installed between the three drainage grooves 41, and the track 5 is installed on the two inclined panels 42, and the three drainage grooves 41 are connected with a drainage pipe 43, and the drainage pipe 43 extends to the outside of the curing bin 1.

[0039] In order to avoid liquid accumulation in the curing bin 1, the water mist condensed on the inner wall of the curing bin 1 slides down the inner wall of the curing bin 1 and enters the drainage groove 41, and the water droplets dripping on the inclined panel 42 and the track 5 slide down the inclined surface of the inclined panel 42 into the drainage groove 41. Finally, the water in the three drainage grooves 41 is discharged from the drain pipe 43 to the outside of the curing bin 1.

[0040] The top of the inclined panel 42 is designed to be ︹, and the track 5 is installed on the plane of the inclined panel 42, and the inclined surfaces on both sides of the inclined panel 42 point to the drainage groove 41, so that water dripping on the track 5 drips along the inclined surface of the inclined panel 42 into the drainage groove 41 for discharge. In this way, the water drops dripping on the inclined panel 42 can easily slide through its inclined surface into the drainage groove 41.

[0041] A folding guide rail 6 is installed on the inner side of the bin cover 2. When the folding guide rail 6 is unfolded, the track 5 is connected to the folding guide rail 6 and connected to the track on the ground, so that the cement bricks and stones are transported to the curing bin 1 by the rail car. When the folding guide rail 6 is retracted, the bin cover 2 is closed by the hydraulic cylinder 3, and the folding guide rail 6 on the bin cover 2 connects the curing bin 1 and the external track 5. After the folding guide rail 6 is retracted, it is convenient to close the bin cover 2 and the curing bin 1. In this way, the rail car can be guided onto the track 5 in the curing bin 1 through the folding guide rail 6 without other external auxiliary equipment, thereby making it more convenient to transfer cement bricks and stones.

[0042] See also Figure 4 The folding guide rail 6 includes a rectangular shell 61 installed on the bin cover 2, and two A rails 67 designed side by side are installed on the top of the rectangular shell 61. Rotatable curved rods 62 are provided on both sides of the rectangular shell 61, and B rails 63 docking with the track 5 are installed on the curved rods 62. A driving mechanism 64 for driving the four curved rods 62 to flip is provided inside the rectangular shell 61. The four curved rods 62 are driven by the driving mechanism 64 to rotate downward, so that the four B rails 63 are laid flat and docked with the A rails 67, and docked with the curing bin 1 and the external track 5. In this way, one group of B rails 63 connects the track 5 and the A rail 67 in the curing bin 1, and the other group of B rails 63 connects the A rail 67 with the external track, so that the rail car can be transferred to the curing bin 1, and the rotating curved rod 62 can control the position of the B rail 63 to facilitate its folding, so that the bin cover 2 is easy to close.

[0043] See also Figure 5The driving mechanism 64 includes two A connecting shafts 65 installed inside the rectangular shell 61 through shaft seats, and the two ends of the A connecting shaft 65 are connected to the bottom of the curved rod 62. A rotatable B connecting shaft 66 is provided between the two A connecting shafts 65, and the two ends of the B connecting shaft 66 are respectively transmitted to the two A connecting shafts 65 through bevel gears, and the B connecting shaft 66 is driven by a motor, so that the B connecting shaft 66 drives the two A connecting shafts 65 to rotate synchronously, and the rotation directions are opposite, so that the two A connecting shafts 65 drive the two sets of tracks 5 to flip up or down at the same time. When the two sets of tracks 5 are laid flat, docking is completed. When the two sets of tracks 5 are erected, the compartment cover 2 needs to be closed.

[0044] See also Figure 6 A slidable spray system 7 is provided inside the curing bin 1, and the spray system 7 moves inside the curing bin 1 and sprays water mist on the cement bricks and stones to moisturize the cement bricks and stones. The spray system 7 includes a plurality of slide rails 71 installed inside the curing bin 1, and a slidable U-shaped frame 72 is provided on the plurality of slide rails 71, and a plurality of atomizing nozzles 73 are installed on the inner side of the U-shaped frame 72. A support beam 74 is installed at the top of the inner wall of the curing bin 1, and a slidable bracket 75 is provided on the support beam 74, and the bracket 75 is installed on the U-shaped frame 72, and a rack is installed on the support beam 74, and a driving gear 76 driven by a motor is installed on the bracket 75, and the rotating driving gear 76 is engaged with the rack to drive the bracket 75 to slide on the support beam 74, so that the U-shaped frame 72 slides along the slide rail 71.

[0045] A water pipe for connecting the atomizing nozzle 73 is installed on the U-shaped frame 72, and the U-shaped frame 72 humidifies the cement bricks on the rail car during the movement. The water mist sprayed by the atomizing nozzle 73 on the U-shaped frame 72 is mixed in the air, and the humidity of the air is increased while humidifying. The flowing air can drive the moisture to contact the cement bricks on the rail car, and the cement bricks on the rail car are stacked in an interval distribution so that there are gaps for air flow between the cement bricks. In this way, the water vapor in the air can better humidify the cement bricks. Using water mist humidification can avoid excessive watering of the cement bricks, and can also ensure that most of the cement bricks are moisturized. The diffusion of water mist into the air can better complete the humidification effect and avoid the cement bricks blocking each other, resulting in the cement bricks in the middle cannot be moisturized.

[0046] A heating device is provided inside the curing bin 1, and the temperature inside the curing bin 1 is increased by the heating device so that the cement masonry can be cured at a suitable temperature.

[0047] A ventilation duct 8 is provided at the top of the curing bin 1, and a vent valve 9 and a fan 10 are connected to the ventilation duct 8. The vent valve 9 is adjusted to make the ventilation duct 8 conductive. While the spray system 7 is humidifying, the fan 10 is running to make the air in the curing bin 1 circulate internally, so that the humidity inside the curing bin 1 is kept consistent. The air inside the curing bin 1 flows, so that a part of the sprayed water mist is mixed in the air to increase the humidity in the curing bin 1, and another part of the sprayed water mist is directly sprayed on the cement bricks and stones.

[0048] Adjust the ventilation valve 9 to seal the ventilation duct 8 and connect it to the outside. When the fan 10 is running, the air inside and outside the curing bin 1 is circulated to remove moisture and avoid excessive humidity inside the curing bin 1. In this environment, cement bricks and stones can be cured in a ventilated environment.

[0049] See also Figure 7 The ventilation valve 9 includes a valve body 91 connected to the ventilation duct 8, and a vent 92 is installed in the middle of the valve body 91, and two air guide ports 93 are opened on the side of the valve body 91, and two hinged valve plates 94 are provided inside the valve body 91, and the two valve plates 94 are respectively located in front and behind the vent 92, and a control structure 95 for controlling the rotation of the two valve plates 94 is provided on the valve body 91, and the control structure 95 includes a protective shell 96 installed on the valve body 91, and two rotatable transmission gears 97 are provided inside the protective shell 96, and the two transmission gears 97 are meshed and driven by a motor, and the shaft ends at the bottom of the two transmission gears 97 are connected to the rotating shaft 98 on the valve plate 94, so that the two valve plates 94 rotate at the same time, and the rotation directions are opposite, so that the two valve plates 94 block the air guide port 93 or the vent 92 at the same time, and control the air flow in the curing bin 1.

[0050] See also Figure 8 When the valve plate 94 blocks the two air guide ports 93 and the fan 10 is running, the air in the curing bin 1 circulates internally. In this state, the air in the curing bin 1 cannot leak out, which can maintain the humidity in the curing bin 1. The flowing air will circulate in the curing bin 1 to moisturize the cement bricks and stones.

[0051] See also Fig. 9 , the valve plate 94 is driven to rotate by the control structure 95, so that the two valve plates 94 block the two ends of the vent 92. When the fan 10 is running, the air can be introduced into the curing bin 1 from the air guide port 93, and the air in the curing bin 1 is discharged from the other air guide port 93. In this way, the outside air is introduced into the curing bin 1, the ventilation inside the curing bin 1 is completed, and the moisture in the curing bin 1 is discharged. In addition, under the ventilation environment, there is not much difference between the inside and outside of the curing bin 1, but it can play a role in shading and preventing rain, and can provide a good natural environment for the maintenance of cement bricks and stones.

[0052] A cement masonry maintenance method, the specific operations are as follows:

[0053] S1, the hydraulic cylinder 3 is used to push the bin cover 2 to rotate downward, so that the bin cover 2 is laid open, and the folding guide rail 6 is unfolded, so that the track 5 in the curing bin 1 is docked with the track on the ground through the folding guide rail 6, so that the rail car drives the cement bricks and stones to be transferred into the curing bin 1, and then the hydraulic cylinder 3 pushes the bin cover 2 to rotate upward, so that the two ends of the curing bin 1 are closed, so that the cement bricks and stones are dried and cured in a closed space;

[0054] S2. After a period of time, the spray system 7 is operated to move the spray system 7 in the curing bin 1 and spray water mist on the moving cement masonry. The ventilation valve 9 is adjusted to make the ventilation duct 8 conductive. The fan 10 is operated to circulate the air in the curing bin 1. The flowing air carries the water mist and circulates in the curing bin 1 to moisturize the surface of the cement masonry. During the moisturizing curing process, the ventilation valve 9 is occasionally adjusted to block the ventilation duct 8. The fan 10 is operated to circulate the air inside and outside the curing bin 1 to remove moisture.

[0055] S3, during the moisturizing curing process, the water mist adheres to the inner wall of the curing chamber 1 to form water droplets that fall onto the drainage system 4, and the water droplets are discharged through the drainage system 4;

[0056] S4. After moisturizing and curing, adjust the vent valve 9 to seal the ventilation duct 8, and circulate the air inside and outside the curing bin 1 through the fan 10, so that the cement bricks and stones in the curing bin 1 can be naturally cured in a ventilated environment. Finally, open the bin cover 2 to export the cured cement bricks and stones.

[0057] Cement masonry is dry-cured in a closed space to avoid excessive evaporation of its own moisture, promote the hydration of cement, and thus accelerate hardening and strength growth. Afterwards, the humidity of the cement masonry is maintained through humidification, and the humidity in the air is increased through atomization. By utilizing the fluidity of the air, most of the surface of the cement masonry can be moisturized to promote the hydration reaction of the cement. Occasional ventilation can dehumidify and reduce the humidity in the environment. Finally, direct ventilation can be used to allow the cement masonry to be naturally cured under a normal environment to prevent the loss of cement slurry and the loss of cement hydration water caused by direct rain and sunlight.

The protection scope of the present invention is defined by the claims.
