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

[0002] Fireproof insulation board is a kind of fireproof material. It belongs to inorganic foam insulation material. It has excellent fire resistance, durability, good interface adhesion, and theoretically can have the same lifespan as the building. Inorganic insulation board is a material that has been sintered and foamed at high temperature. It has a high closed-cell rate and extremely low water absorption. Compared with foam cement, it can be lighter in bulk density, has a relatively low thermal conductivity, and has a 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 stacked 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 absorption of microwave heating, resulting in different degrees of drying between the fireproof insulation boards at the same time.

The fireproof insulation board processing device and processing method, when the fireproof insulation board is placed on the 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, so that the fireproof insulation board is dried more evenly, and 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 pusher, the glass fiber mesh cloth and the fireproof insulation board on the top thereof in turn, so that the interval gaps between the fireproof insulation boards 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.

DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] See also Figure 1-9 A fireproof insulation board processing device comprises a microwave drying oven 1 and a controller. A sealing door 11 is hingedly connected to the outside of the microwave drying oven 1. A placement groove 12 is provided 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 is composed 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 installation cavity 3 and a second installation cavity 31 are provided inside the top plate of the microwave drying oven 1, a dehumidification pipe 32 is fixed inside the second installation cavity 31, the dehumidification pipe 32 is connected to the inside 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, and the support assembly is used to support the heat preservation plate;

[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 box 1, the main support frame 4 is provided with a first slide groove 43, the first support frame 41 is provided with a second slide groove 44, and the second support frame 42 is provided with a third slide groove 45, and the number and height of the first slide groove 43, the second slide groove 44 and the third slide groove 45 are consistent;

[0038] A ceramic frame 5 is slidably connected inside the first slide groove 43, and the ceramic frame 5 is slidably connected to the second slide groove 44 and the third slide groove 45 at the same time. A glass fiber mesh cloth 51 is fixed on the surface of the ceramic frame 5. A limiting frame 52 is fixed on the top of the ceramic frame 5 close to the second installation cavity 31. A metal push head 53 is fixed on the outside of the glass fiber mesh cloth 51 away from the limiting frame 52. Ceramic springs 54 are fixed on both sides of one end of the ceramic frame 5 close to the limiting 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, and 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, and the first motor 6 is controlled by a controller. The external transmission of the output shaft of the first motor 6 is connected with a belt 61, and the internal rotation of the bottom plate of the first installation cavity 3 is connected with a metal blade 62, and the metal blade 62 is connected with the belt 61 in a transmission manner;

[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 heat-insulating boards are stacked on the top of each glass fiber mesh cloth 51 in sequence, until the fireproof heat-insulating boards are placed on the top of all the glass fiber mesh cloths 51, and then the sealing door 11 is closed, and then the microwave emitting device 13 is started by the controller, and the microwave emitting device 13 radiates microwaves to the inside of the microwave drying oven 1, so that the microwaves are irradiated from the bottom of the microwave drying oven 1 toward the direction of 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 heat-insulating boards, and directly heat and dry the inside of the fireproof heat-insulating 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 blade 62 is driven to rotate by the belt 61. During the rotation process, the metal fan blade 62 reflects the microwaves that penetrate the fireproof insulation board. Due to the continuous rotation of the metal fan blade 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 reflection by the metal blades 62, part of the microwaves will return along the original path, that is, return from the metal blades 62 toward the direction of the microwave emitting device 13. During the return process, the fireproof insulation board can be heated and dried again, so that the surface of the fireproof insulation board can be evenly heated and dried.

[0043] Furthermore, on the basis of the ceramic screw 63 changing the microwave irradiation angle, part of the microwave is reflected on the surface of the metal reflector 2, and more microwaves are reflected into the interval gaps of the fireproof insulation board through the multiple arc surfaces on the surface of the metal reflector 2, making it easier for the microwave to heat and dry each layer of the fireproof insulation board;

[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 box 1 through the exhaust port 33 under the guidance of the dehumidification pipe 32, thereby avoiding excessive humidity inside the microwave drying box 1 and affecting the drying of the fireproof insulation board.

[0045] Embodiment 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, and ceramic limit rods 64 are fixed to the bottom plate of the microwave drying box 1 on both sides of the ceramic screw 63. The bottom of the ceramic screw 63 is rotatably connected to the bottom plate of the microwave drying box 1, and the external thread of the ceramic screw 63 is connected to the aluminum tube 7, and the aluminum tube 7 is slidably connected to the two ceramic limit rods 64, and a ceramic cover plate 71 is fixed to the outside of the aluminum tube 7;

[0047] A first inner groove 72 is provided 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 provided inside the aluminum tube 7 on both sides of the first inner groove 72, and the output shaft of the second motor 73 passes through the inner wall of the first inner groove 72. A fan blade roller 75 is fixed outside the output shaft of the second motor 73, and the fan blade 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. The ceramic screw 63 drives the aluminum tube 7 to move during the rotation, and the aluminum tube 7 moves along the ceramic screw 63, and the aluminum tube 7 drives the ceramic cover plate 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 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 head 53 in turn, and as the ceramic cover plate 71 moves, the metal pusher head 53 drives the glass fiber mesh cloth 51 to move toward the metal reflector plate 2, so that the glass fiber mesh cloth 51 drives the fireproof insulation board to move toward the metal reflector plate 2. Due to the spacing difference between each glass fiber mesh cloth 51, there is a time difference when each fireproof insulation board moves toward the metal reflector plate 2.

[0050] When the ceramic cover plate 71 contacts any one of the metal pushers 53, the metal pusher 53 together with the glass fiber mesh cloth 51 fixed thereto and the fireproof heat-insulating plate located on the top of the glass fiber mesh cloth 51 move toward the metal reflector 2, and the fireproof heat-insulating plate and the two fireproof heat-insulating plates adjacent to it above and below are in a staggered state, that is, the original position of the shielding is changed, and then the position of the microwave irradiation on the fireproof heat-insulating plate is changed, 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, so that each fireproof insulation board receives microwave heating more comprehensively, 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 cloth 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 origin and wait for the next cycle of contact with 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 is in contact with 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 is also constantly changing, thereby causing the microwaves to be more evenly distributed between the fireproof insulation boards, and causing the fireproof insulation boards to receive microwave heating more evenly, 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 the 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 adjacent to 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, and then the microwaves received by the three boards can be more fully, further improving the efficiency of microwave heating and drying;

[0055] And with the reciprocating movement of the ceramic cover plate 71, each metal pusher head 53 moves toward the metal reflector plate 2 in sequence and regularly, so that after any metal pusher head 53 and the glass fiber mesh cloth 51 drive the fireproof insulation board on its top to move toward the metal reflector plate 2, the gap between the two adjacent fireproof insulation boards can be stably and evenly expanded, thereby making the gap 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 pusher head 53 are both made of aluminum alloy material to ensure the reflection efficiency of microwaves and reduce the absorption of microwaves.

[0057] Embodiment three:

[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 blade 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, when the ceramic cover plate 71 continues to absorb part of the microwaves, it will gradually heat up, and 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, and when the airflow passes through the ceramic cover plate 71, the temperature of the airflow can be increased by heating the ceramic cover plate 71 to become warm air, and then the fireproof insulation board is air-dried by the warm air;

[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 heat-insulating board, using the fireproof heat-insulating board processing device as described above, comprises the following steps:

[0062] S1: After opening the sealing door 11, the fireproof insulation board is stacked on the top of each glass fiber mesh cloth 51 in sequence, thereby completing the layered stacking, and then the sealing door 11 is closed, and the microwave transmitting device 13 is started by the controller to perform microwave drying on the fireproof insulation board on the top of the glass fiber mesh cloth 51;

[0063] 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 heat preservation 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 the top thereof to move synchronously, thereby changing the position of the fireproof insulation board receiving microwaves;

[0065] S4: While the aluminum tube 7 is reciprocating, the first inner groove 72 is activated by the controller, and the fan roller 75 is driven by the first inner groove 72 to rotate, generating airflow, which is blown to each fireproof insulation board through the ceramic cover plate 71, and the fireproof insulation board is further dried through the cooperation of microwave and wind blowing.

[0066] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

7. A fireproof insulation board processing device according to claim 6, characterized in that: A first inner groove (72) is provided on both sides of the middle position of the aluminum tube (7), a second motor (73) is fixed inside the first inner groove (72), a second inner groove (74) is provided inside the aluminum tube (7) on both sides of the first inner groove (72), an output shaft of the second motor (73) passes through the inner wall of the first inner groove (72), and a fan blade roller (75) is fixed outside the output shaft of the second motor (73), and the fan blade roller (75) is located inside the second inner groove (74).

8. A method for processing a fireproof and heat-insulating board, using the fireproof and heat-insulating board processing device according to claim 7, characterized in that: The following steps are involved: S1: After opening the sealing door (11), the fireproof heat-insulating panels are stacked on top of each glass fiber mesh cloth (51) in sequence, thereby completing the layered stacking, and 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 heat-insulating panels 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 heat-insulating board is evenly dried by microwaves; S3: When the first motor (6) is started, it drives the ceramic screw (63) to rotate, and drives the aluminum tube (7) to move up and down 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 head (53) in turn during the movement, so that the metal pusher head (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), and the fireproof insulation board is further dried by the combination of microwaves and wind blowing.
