[0001] The present invention relates to the technical field of fireproof and heat-insulating board processing, in particular to a fireproof and heat-insulating board processing device and a processing method. Background Art

[0002] Fireproof insulation board is a fireproof material. It is an inorganic foam insulation material with excellent fire resistance, durability, and good interfacial adhesion. Theoretically, it can last the same life as the building. Inorganic insulation board is a material that is foamed and formed by high-temperature sintering. It has a high closed-cell ratio and extremely low water absorption. Compared to foam cement, it has a lighter bulk density, a relatively lower thermal conductivity, and slightly higher strength.

[0003] During the production process, after demoulding and shaping, the fireproof insulation board needs to be sprayed with cold water to accelerate the cooling and shaping speed of the fireproof insulation board. After the fireproof insulation board is completely shaped, it needs to be dried. The fireproof insulation board is generally dried by natural air drying, hot air drying, ultraviolet drying or microwave drying.

[0004] In the prior art, when using a microwave drying oven to dry fireproof insulation boards, the fireproof insulation boards are generally placed in a stacked manner in the microwave drying oven for drying. However, when drying the fireproof insulation boards in this stacking manner, since the fireproof insulation boards have a certain area, after being stacked, the fireproof insulation boards will block each other, which in turn affects the contact area and position between the microwaves and the fireproof insulation boards and the degree of microwave heating absorption, resulting in different degrees of drying between the fireproof insulation boards at the same time.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The fireproof insulation board processing device and processing method, when the fireproof insulation board is placed on top of each glass fiber mesh cloth, the microwave transmitting device is started by the controller to perform microwave drying on the fireproof insulation board, and the first motor is started to rotate forward and reverse regularly. The first motor drives the belt and the ceramic screw to rotate at the same time, and the belt drives the metal fan blades to rotate, and then reflects the microwaves to different angles, so as to optimize the distribution of microwaves and make the fireproof insulation board dry more evenly. At the same time, the ceramic screw drives the aluminum tube to move up and down along the ceramic screw, so that the aluminum tube drives the ceramic cover plate to push the metal push head, the glass fiber mesh cloth and the fireproof insulation board on the top thereof in turn, so that the gaps between each fireproof insulation board are regularly expanded, and then the microwaves are more easily irradiated on each fireproof insulation board, thereby improving the drying efficiency of the fireproof insulation board.

[0022] 2.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1:

[0035] See also Figure 1-9 A fireproof insulation board processing device includes a microwave drying oven 1 and a controller. The microwave drying oven 1 is hinged with a sealing door 11 on the outside. A placement groove 12 is opened at the bottom of the microwave drying oven 1. A microwave emitting device 13 is fixed inside the placement groove 12. The microwave emitting device 13 consists of a magnetron and a waveguide tube and is controlled by the controller.

[0036] A metal reflective plate 2 is fixed to the inner wall of one side of the microwave drying oven 1. A first mounting cavity 3 and a second mounting cavity 31 are provided inside the top plate of the microwave drying oven 1. A dehumidification pipe 32 is fixed inside the second mounting cavity 31. The dehumidification pipe 32 is connected to the interior of the microwave drying oven 1. An exhaust port 33 is provided on the top of the microwave drying oven 1. The exhaust port 33 is connected to the dehumidification pipe 32. A support assembly is provided inside the microwave drying oven 1 for supporting the insulation board.

[0037] The support assembly includes a main support frame 4, a first support frame 41 and a second support frame 42, and the main support frame 4, the first support frame 41 and the second support frame 42 are all fixed to the bottom of the inner cavity of the microwave drying oven 1. A first chute 43 is opened inside the main support frame 4, a second chute 44 is opened inside the first support frame 41, and a third chute 45 is opened inside the second support frame 42. The number and height of the first chute 43, the second chute 44 and the third chute 45 are consistent;

[0038] The first slide groove 43 is internally slidably connected to a ceramic frame 5, and the ceramic frame 5 is simultaneously slidably connected to the second slide groove 44 and the third slide groove 45. A glass fiber mesh cloth 51 is fixed to the surface of the ceramic frame 5. A limit frame 52 is fixed to the top of the ceramic frame 5 close to the second installation cavity 31. A metal push head 53 is fixed to the outside of the glass fiber mesh cloth 51 away from the limit frame 52. Ceramic springs 54 are fixed on both sides of one end of the ceramic frame 5 close to the limit frame 52, and the two ceramic springs 54 are respectively located inside the first slide groove 43 and the second slide groove 44, and are fixed to the inner walls of the first slide groove 43 and the second slide groove 44;

[0039] The metal push head 53 is fixed to the ceramic frame 5. Both sides of the top and bottom of the metal push head 53 are arranged in an arc shape. A first motor 6 is fixed inside the first installation cavity 3. The first motor 6 is controlled by a controller. The external transmission of the output shaft of the first motor 6 is connected to a belt 61. The interior of the bottom plate of the first installation cavity 3 is rotatably connected to a metal fan blade 62, and the metal fan blade 62 is transmission-connected to the belt 61.

[0040] During the specific operation, the sealing door 11 is first pulled to open the microwave drying oven 1, and then the water-containing fireproof insulation boards are stacked on top of each glass fiber mesh cloth 51 in sequence. After the fireproof insulation boards are placed on top of all the glass fiber mesh cloths 51, the sealing door 11 is closed, and then the microwave emitting device 13 is activated by the controller. The microwave emitting device 13 radiates microwaves into the interior of the microwave drying oven 1, so that the microwaves are irradiated from the bottom of the microwave drying oven 1 toward the metal fan blades 62, so that the microwaves pass through the bottom of the microwave drying oven 1 and each glass fiber mesh cloth 51, and penetrate the fireproof insulation boards, directly heating and drying the interior of the fireproof insulation boards;

[0041] Specifically, during the microwave heating of the fireproof insulation board, the first motor 6 is started by the controller, so that the first motor 6 rotates slowly, and then the belt 61 is driven to rotate by the first motor 6, and then the metal fan blades 62 are driven to rotate by the belt 61. During the rotation process, the metal fan blades 62 reflect the microwaves that have penetrated the fireproof insulation board. Due to the continuous rotation of the metal fan blades 62, the angle of the reflected microwaves also changes continuously, thereby optimizing the distribution of microwaves inside the microwave drying box 1, so that the microwaves can more evenly penetrate the gaps between the fireproof insulation boards, and evenly heat and dry the fireproof insulation boards.

[0042] Under the effect of the reflection of the metal blades 62, part of the microwaves will return along the original path, that is, return from the metal blades 62 toward the microwave emitting device 13. During the return process, the fireproof insulation board can be heated and dried again, thereby making the surface of the fireproof insulation board evenly heated and dried.

[0043] Furthermore, based on the ceramic screw 63 changing the microwave irradiation angle, part of the microwave is reflected on the surface of the metal reflector 2. Through the multiple curved surfaces of the metal reflector 2, more microwaves are reflected into the gaps between the fireproof insulation boards, making it easier for the microwaves to heat and dry each layer of the fireproof insulation boards.

[0044] After the fireproof insulation board is heated, the water vapor generated enters the second installation cavity 31 and is discharged to the outside of the microwave drying oven 1 through the exhaust port 33 under the guidance of the dehumidification pipe 32, thereby avoiding excessive humidity inside the microwave drying oven 1, which in turn affects the drying of the fireproof insulation board.

[0045] Example 2:

[0046] The output shaft of the belt 61 passes through the bottom plate of the first installation cavity 3, and a ceramic screw 63 is fixed to the outside of the output shaft of the first motor 6. Ceramic limit rods 64 are fixed to both sides of the bottom plate of the microwave drying oven 1. The bottom of the ceramic screw 63 is rotatably connected to the bottom plate of the microwave drying oven 1. The external thread of the ceramic screw 63 is connected to the aluminum tube 7. The aluminum tube 7 is slidably connected to the two ceramic limit rods 64. A ceramic cover plate 71 is fixed to the outside of the aluminum tube 7.

[0047] A first inner groove 72 is formed on both sides of the middle position of the aluminum tube 7, and a second motor 73 is fixed inside the first inner groove 72. A second inner groove 74 is formed inside the aluminum tube 7 on both sides of the first inner groove 72. The output shaft of the second motor 73 passes through the inner wall of the first inner groove 72, and a fan roller 75 is fixed outside the output shaft of the second motor 73. The fan roller 75 is located inside the second inner groove 74;

[0048] During the specific operation, when the first motor 6 is started, the first motor 6 drives the ceramic screw 63 to rotate at the same time. During the rotation of the ceramic screw 63, the aluminum tube 7 is driven to move, and the aluminum tube 7 moves along the ceramic screw 63, and the aluminum tube 7 drives the ceramic cover 71 to move synchronously. At this time, the first motor 6 can be controlled by the controller to rotate forward and reverse, and the time of the forward and reverse rotation of the first motor 6 can be set, so that the first motor 6 drives the ceramic screw 63 to rotate forward and reverse, and then the aluminum tube 7 is reciprocated on the surface of the ceramic screw 63.

[0049] When the aluminum tube 7 drives the ceramic cover plate 71 to move back and forth along the ceramic screw 63, the ceramic cover plate 71 contacts each metal pusher 53 in turn, and as the ceramic cover plate 71 moves, the metal pusher 53 drives the glass fiber mesh cloth 51 to move toward the metal reflector 2, so that the glass fiber mesh cloth 51 drives the fireproof insulation board to move toward the metal reflector 2. Due to the difference in spacing between the glass fiber mesh cloths 51, there is a time difference when each fireproof insulation board moves toward the metal reflector 2.

[0050] When the ceramic cover plate 71 comes into contact with any one of the metal push heads 53, the metal push head 53, together with the glass fiber mesh cloth 51 fixed thereto, and the fireproof heat-insulating plate located on top of the glass fiber mesh cloth 51, moves toward the metal reflector 2. The fireproof heat-insulating plate and the two fireproof heat-insulating plates above and below it are in a staggered state, that is, the position where the original obstruction exists is changed, thereby causing the position of the microwave irradiation on the fireproof heat-insulating plate to change, thereby making the fireproof heat-insulating plate moving toward the metal reflector 2 more evenly heated.

[0051] The ceramic cover plate 71 contacts each metal pusher 53 in turn, and then each fireproof insulation board moves toward the metal reflector 2 in a regular time period, thereby making the microwave heating between each fireproof insulation board more comprehensive, thereby improving the efficiency of microwave drying;

[0052] When the metal pusher 53 loses the pressure from the ceramic cover plate 71, the ceramic spring 54 drives the glass fiber mesh 51, the fireproof insulation board and the metal pusher 53 to reset under the action of the elastic force of the ceramic spring 54, thereby ensuring that the metal pusher 53 can be reset to the original point and wait for the next contact cycle of the ceramic cover plate 71, while preventing the two fireproof insulation boards from approaching the metal reflector 2 at the same time;

[0053] Furthermore, when the metal pusher 53 is not in contact with the ceramic cover plate 71, the metal pusher 53 can reflect the microwaves into the gaps between the fireproof insulation boards, thereby improving the uniformity of heating and drying between the fireproof insulation boards in the stacked state. When the metal pusher 53 contacts the ceramic cover plate 71, the position of the metal pusher 53 changes, thereby causing the position of the metal pusher 53 receiving the microwaves to change. In addition, during the continuous movement of the metal pusher 53, the angle of the reflected microwaves also changes continuously, thereby making the microwaves more evenly distributed between the fireproof insulation boards, making the fireproof insulation boards more evenly heated by microwaves, thereby improving the drying efficiency of the fireproof insulation boards.

[0054] At the same time, when the metal pusher 53 moves, the metal pusher 53 and the fireproof insulation board on top of the glass fiber mesh cloth 51 move toward the metal reflector 2, and the gap between the fireproof insulation board and the two fireproof insulation boards above and below it is expanded, so that the microwaves reflected by the metal reflector 2 can more easily enter the gaps between the three fireproof insulation boards, thereby making the microwaves received by the three boards more sufficient, further improving the efficiency of microwave heating and drying;

[0055] And as the ceramic cover plate 71 moves back and forth, each metal push head 53 moves toward the metal reflector 2 in sequence and regularly, so that after any metal push head 53 and the glass fiber mesh cloth 51 drive the fireproof insulation board on its top to move toward the metal reflector 2, the gaps between the two adjacent fireproof insulation boards can be stably and evenly expanded, thereby making the gaps between each fireproof insulation board expand in a periodic and regular state, thereby making the efficiency of microwave heating between each fireproof insulation board the same, thereby ensuring that each fireproof insulation board is evenly heated and dried.

[0056] It should be noted that the metal reflective plate 2 and the metal push head 53 are both made of aluminum alloy material to ensure the reflection efficiency of microwaves and reduce the absorption of microwaves.

[0057] Example 3:

[0058] During the specific operation, based on the first and second embodiments, when the first motor 6 drives the ceramic screw 63 to rotate, and the ceramic screw 63 drives the aluminum tube 7 to drive the ceramic cover plate 71 to move back and forth along the ceramic screw 63, the second motor 73 is started by the controller. When the second motor 73 is started, the second motor 73 drives the fan roller 75 to rotate inside the second inner groove 74, thereby generating airflow, and the airflow passes through the ceramic cover plate 71 and blows toward each fireproof insulation board;

[0059] Furthermore, since part of the microwaves emitted by the microwave emitting device 13 will be absorbed by the ceramic cover plate 71, the ceramic cover plate 71 will gradually heat up after continuously absorbing part of the microwaves. The ceramic cover plate 71 is located outside the aluminum tube 7. When the second inner groove 74 rotates to generate airflow, the airflow will pass through the ceramic cover plate 71 and blow toward the fireproof insulation board. When the airflow passes through the ceramic cover plate 71, the ceramic cover plate 71 heats the airflow, which can increase the temperature of the airflow and become warm air. The warm air then dries the fireproof insulation board.

[0060] Since microwave heating starts from the inside of the fireproof insulation board, the moisture on the surface of the fireproof insulation board dries relatively slowly. Therefore, the overall drying degree of the inside and outside of the fireproof insulation board is accelerated by combining air drying and microwave drying. Under the influence of airflow, the water vapor generated by the drying of the fireproof insulation board can be blown to the bottom of the second installation cavity 31, and finally the water vapor enters the inside of the second installation cavity 31 and is discharged to the outside through the dehumidification pipe 32 and the exhaust port 33.

[0061] A method for processing a fireproof and heat-insulating board, using the fireproof and heat-insulating board processing device as described above, comprises the following steps:

[0062] S1: After opening the sealing door 11, the fireproof insulation boards are stacked on top of each glass fiber mesh cloth 51 in sequence to complete the layered stacking. Then, the sealing door 11 is closed and the microwave emitting device 13 is activated by the controller to perform microwave drying on the fireproof insulation boards on top of the glass fiber mesh cloth 51.

[0063] S2: During the microwave drying process, the controller starts the first motor 6, which drives the belt 61 to rotate the metal fan blades 62. During the rotation, the metal fan blades 62 continuously reflect the microwaves emitted by the microwave emitting device 13, so that the microwaves are evenly distributed inside the microwave drying box 1, and the fireproof insulation board is evenly dried by microwaves;

[0064] S3: When the first motor 6 is started, it drives the ceramic screw 63 to rotate, and drives the aluminum tube 7 to rise and fall on the surface of the ceramic limit rod 64. At this time, the controller sets the forward and reverse rotation time and cycle of the first motor 6, so that the aluminum tube 7 drives the ceramic cover plate 71 to move back and forth on the surface of the ceramic limit rod 64, and pushes each metal pusher 53 in turn during the movement, so that the metal pusher 53 drives the glass fiber mesh cloth 51 and the fireproof insulation board on top thereof to move synchronously, thereby changing the position of the fireproof insulation board receiving microwaves;

[0065] S4: As the aluminum tube 7 reciprocates, the controller activates the first inner groove 72, which drives the fan roller 75 to rotate, generating airflow, which is blown toward each fireproof insulation board through the ceramic cover 71. The fireproof insulation board is further dried through the combination of microwaves and wind.

[0066] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

A method for processing a fireproof and heat-insulating board, using the fireproof and heat-insulating board processing device according to claim 2, characterized in that: The following steps are involved: S1: After opening the sealing door (11), the fireproof insulation board is stacked on top of each glass fiber mesh cloth (51) in sequence to complete the layered stacking, and then the sealing door (11) is closed, and the microwave emission device (13) is activated by the controller to perform microwave drying on the fireproof insulation board on top of the glass fiber mesh cloth (51); S2: During the microwave drying process, the first motor (6) is started by the controller. After the first motor (6) is started, the belt (61) is driven to drive the metal fan blade (62) to rotate. During the rotation process, the metal fan blade (62) continuously reflects the microwaves emitted by the microwave emitting device (13), so that the microwaves are evenly distributed inside the microwave drying box (1), and the fireproof insulation board is evenly dried by microwaves; S3: When the first motor (6) is started, the ceramic screw (63) is driven to rotate, and the aluminum tube (7) is driven to move up and down on the surface of the ceramic limit rod (64). At this time, the forward and reverse rotation time and cycle of the first motor (6) are set by the controller, so that the aluminum tube (7) drives the ceramic cover plate (71) to move back and forth on the surface of the ceramic limit rod (64), and pushes each metal pusher (53) in turn during the movement, so that the metal pusher (53) drives the glass fiber mesh cloth (51) and the fireproof insulation board on the top thereof to move synchronously, thereby changing the position of the fireproof insulation board receiving microwaves; S4: While the aluminum tube (7) is moving back and forth, the first inner groove (72) is activated by the controller, and the fan roller (75) is driven to rotate by the first inner groove (72), thereby generating airflow, which is blown toward each fireproof insulation board through the ceramic cover plate (71). The fireproof insulation board is further dried by the combination of microwaves and wind.
