Description

Technical Field

[0001] The invention relates to the field of ceramic fiberboard processing, and in particular to a ceramic fiberboard production and processing device. Background Art

[0002] Ceramic fiberboard generally refers to aluminum silicate fiberboard, which is processed by wet vacuum forming process. The strength of this type of product is higher than that of fiber blanket and vacuum formed felt, and it is suitable for high-temperature fields that require rigid strength of the product.

[0003] The manufacturing process of ceramic fiberboard requires drying operation. For example, Chinese patent CN210374358U discloses a ceramic fiberboard drying machine, which separates a plurality of ceramic fiberboards from each other in an upright state so that the water vapor between the ceramic fiberboards can flow and be discharged quickly. Most existing drying equipment also adopts the method of vertical separation placement or horizontal stacking for drying. However, since the moisture on the ceramic fiberboard will be deposited downward under the action of gravity during the placement process, and the water vapor will evaporate upward, most of the water vapor will continue to pass through the ceramic fiberboard from bottom to top, causing the evaporated water vapor to adhere to the ceramic fiberboard, resulting in poor water vapor extraction effect. Summary of the invention

[0004] In order to overcome the disadvantage that the way of placing ceramic fiber boards in existing drying equipment is not conducive to the direct discharge of water vapor, the present invention provides a ceramic fiber board production and processing device.

[0006] Furthermore, each of the air suction grooves is located above one of the connecting rods.

[0007] Furthermore, the connecting rod is composed of a motor and a rod body, and the motor drives the rod body to rotate to drive the supporting rod to rotate. All the supporting rods on each connecting rod are commonly connected to a limiting rod on one side close to the placement rack.

[0008] Furthermore, two telescopic driving members are respectively installed on both sides of the drying box, and the telescopic ends of the telescopic driving members are inserted into the drying box. The telescopic ends of the two telescopic driving members on each side are commonly installed with a movable plate, and the two movable plates are respectively distributed on both sides of the placement rack, and the movable plates are fitted with the inner wall of the drying box, and the heating module is located in the space between the two movable plates.

[0009] Furthermore, a heat insulation layer is provided on opposite sides of the two movable plates.

[0010] Furthermore, the supporting rod and the limiting rod are both provided with cavities, and the internal cavity of the supporting rod is communicated with the internal cavity of the connected limiting rod, three suction grooves 2 are provided on the supporting rod, and the internal cavity of the supporting rod is communicated with the outside world through the suction grooves 2, and a pipeline module is provided on the placement rack, and the pipeline module is used to connect the internal cavity of the limiting rod, the internal cavity of the placement rack and the external air pump.

[0014] Furthermore, the heating module is composed of a plurality of heating tubes, and all the heating tubes are equidistantly installed on the inner wall of the drying box.

[0015] The beneficial effects of the present invention are as follows: the present invention enables the ceramic fiber board to be tilted during the drying process, and the lower end of the ceramic fiber board is close to one side of the placement rack, so that the moisture on the ceramic fiber board gradually gathers toward the lower end under the action of gravity, so that most of the moisture on the ceramic fiber board gathers at a position close to the air suction groove one, and at the same time, with the suction of the air suction groove one, the water vapor dried out can be directly sucked away without re-attaching to the ceramic fiber board, thereby ensuring the water vapor extraction effect to the greatest extent.

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1

[0026] A ceramic fiberboard production and processing device, such as Figure 1-Figure 5 As shown, it includes a drying box 1 and a heating module, and the heating module is installed in the drying box 1;

[0027] Also includes:

[0028] A placing rack 2, the placing rack 2 is installed in the drying box 1, a cavity is opened in the placing rack 2, four air suction grooves 21 are opened on both sides of the placing rack 2, and the cavity in the placing rack 2 is connected to the outside through the air suction grooves 21;

[0029] Connecting rods 3, wherein the connecting rods 3 are arranged in two vertical rows, one vertical row is composed of four connecting rods 3, and the connecting rods 3 in the two vertical rows are distributed on both sides of the placement rack 2;

[0030] Support rods 4 , three support rods 4 are equidistantly mounted on each of the connecting rods 3 .

[0031] Each of the air suction grooves 21 is located above one of the connecting rods 3 .

[0032] The connecting rod 3 is composed of a motor and a rod body, and all the supporting rods 4 on each connecting rod 3 are connected to a limiting rod 5 on one side close to the placement rack 2 .

[0033] The door of the drying box 1 is not shown in the figure. The door of the drying box 1 is a well-known structure and will not be described in detail here.

[0034] It should be noted that the parts structure in this device are all made of high temperature resistant materials to ensure that they can withstand the drying temperature.

[0035] In this embodiment, after the worker opens the door of the drying box 1, the ceramic fiber board to be dried is placed in the drying box 1. The placement method is to place a ceramic fiber board on all the supporting rods 4 on each connecting rod 3, and then the door of the drying box 1 is closed. The heating module in the drying box 1 is used to heat and dry the ceramic fiber board. The drying time and drying temperature of the ceramic fiber board are common knowledge and are not described here.

[0036] When placing the ceramic fiberboard, the supporting rod 4 is kept in a horizontal state so that the workers can put it in. When drying starts, the motor of the connecting rod 3 drives the rod body to rotate, so that the supporting rod 4 rotates to an inclined state, so that the ceramic fiberboard also becomes an inclined state synchronously, and the limiting rod 5 assists in supporting the inclined ceramic fiberboard. During the drying process, suction is performed by an external air pump, and the water vapor generated by drying is sucked away through the suction groove 21 of the placement rack 2. The present invention realizes that the ceramic fiberboard is tilted during the drying process, and the end of the ceramic fiberboard with a lower height is close to one side of the placement rack 2, so that the moisture on the ceramic fiberboard gradually converges to the end with a lower height under the action of gravity, so that most of the moisture on the ceramic fiberboard is gathered at a position close to the suction groove 21, and at the same time, with the suction at the suction groove 21, the water vapor generated by drying can be directly sucked away without being re-attached to the ceramic fiberboard, thereby ensuring the water vapor extraction effect to the greatest extent.

[0037] Furthermore, the positions of the air suction grooves 21 and the placement positions of the ceramic fiber boards are staggered, so that the water vapor between the two adjacent ceramic fiber boards above and below will not be blocked and stay, further ensuring the water vapor extraction effect.

[0038] Example 2

[0039] On the basis of Example 1, Figure 1-Figure 2As shown, two telescopic driving members 8 are respectively installed on both sides of the drying box 1, and the telescopic driving members 8 are electric push rods. The telescopic ends of the telescopic driving members 8 penetrate into the drying box 1, and the telescopic ends of the two telescopic driving members 8 on each side are commonly installed with a movable plate 9, and the two movable plates 9 are respectively distributed on both sides of the placement rack 2, and the movable plates 9 are in contact with the inner wall of the drying box 1, and the heating module is located in the space between the two movable plates 9.

[0040] Heat insulation layers are provided on opposite sides of the two moving plates 9 to ensure that heat is concentrated in the space between the two moving plates 9 .

[0041] In this embodiment, considering that there is more water vapor in the early stage of the drying process, a larger space needs to be reserved for the water vapor to overflow. Therefore, the rotation inclination angle of the support rod 4 is smaller in the early stage of the drying process, so that the space between the upper and lower adjacent ceramic fiber boards is larger. In the later stage of the drying process, the moisture on the ceramic fiber boards gradually decreases, and the overflowing water vapor also gradually decreases, so there is no need for a larger space. Therefore, when the drying work reaches the middle and late stages, the motor of the connecting rod 3 drives the rod body to continue to rotate to increase the inclination angle of the supporting rod 4, that is, Figure 5 As shown, the telescopic driving member 8 is synchronously controlled to drive the moving plate 9 to move, so that the two moving plates 9 move toward each other to reduce the space between the two moving plates 9, so that the heat emitted by the heating module is more concentrated, and the drying space can be adaptively adjusted at different stages of the drying process to ensure the best drying effect;

[0042] Moreover, when the inclination angle of the supporting rod 4 increases, the distance between the upper and lower adjacent ceramic fiber boards is also reduced accordingly, so that when the suction power of the external air pump remains unchanged, the suction space is reduced to increase the strength of sucking water vapor, ensuring that a high suction efficiency is maintained when water vapor overflow is reduced. At the same time, there is no need to increase the suction power, which is energy-saving and environmentally friendly.

[0043] After the drying of the ceramic fiber board is completed, it is necessary to wait for the temperature of the ceramic fiber board to drop. At this time, the support rod 4 is controlled to rotate to a horizontal state so that the distance between the upper and lower adjacent ceramic fiber boards reaches the maximum. At the same time, the telescopic drive member 8 is controlled to drive the movable plate 9 to move so that the two movable plates 9 are away from each other, thereby increasing the space around the placement position of the ceramic fiber board, so that the heat at the ceramic fiber board can be quickly dissipated and the cooling efficiency of the ceramic fiber board is improved.

[0044] Example 3

[0045] On the basis of Example 2, Figure 1-Figure 4As shown, the supporting rod 4 and the limiting rod 5 are both provided with cavities, and the internal cavity of the supporting rod 4 is communicated with the internal cavity of the connected limiting rod 5, three suction grooves 41 are provided on the supporting rod 4, and the internal cavity of the supporting rod 4 is communicated with the outside world through the suction grooves 41, and a pipeline module is provided on the placement rack 2.

[0046] The pipeline module includes a telescopic hose 6 and a connecting pipe 7. The connecting pipe 7 is installed at the bottom of the placement rack 2. The internal cavities of the two upper and lower adjacent limit rods 5 are connected through a telescopic hose 6. The connecting pipe 7 is provided with three branches. The three branches of the connecting pipe 7 are all provided with solenoid valves. One of the branches of the connecting pipe 7 is connected to the internal cavity of the placement rack 2, and the other two branches of the connecting pipe 7 are respectively connected to the internal cavities of the two lowest limit rods 5 through a telescopic hose 6. The connecting pipe 7 is connected to an external air pump.

[0047] The lengths of the three air suction grooves 41 on the supporting rod 4 decrease gradually from the side close to the placement rack 2 to the side away from the placement rack 2 .

[0048] The second air suction groove 41 is disposed on the side surface of the supporting rod 4 .

[0049] The heating module is composed of three heating tubes 10 , and all the heating tubes 10 are equidistantly installed on the inner wall of the drying box 1 , and the drying box 1 is heated by the heating tubes 10 .

[0050] In this embodiment, considering that when the inclination angle of the supporting rod 4 is increased as mentioned above, the distance between the upper and lower adjacent ceramic fiber boards is reduced, and the air suction groove 21 is distributed on one side between the upper and lower adjacent ceramic fiber boards, the suction effect of the air suction groove 21 on the side of the ceramic fiber board away from the placement rack 2 will decrease, so an air suction groove 2 41 is designed, and the air suction groove 2 41 is distributed in the space between the upper and lower adjacent ceramic fiber boards, and due to the inclined state of the ceramic fiber board, the moisture content on the ceramic fiber board gradually increases from the side away from the placement rack 2 to the side close to the placement rack 2, so the three air suction grooves 2 41 on the supporting rod 4 are designed to decrease in length from the side close to the placement rack 2 to the side away from the placement rack 2, so as to adapt to the moisture content of the ceramic fiber board at different positions.

[0051] The worker connects the connecting pipe 7 to the external air pump. In the early stage of the drying process, suction is required at the suction groove 21. By controlling the opening and closing of the solenoid valve on the branch pipe of the connecting pipe 7, the branch pipe connecting the connecting pipe 7 and the telescopic hose 6 is closed, and the branch pipe connecting the connecting pipe 7 and the placement rack 2 is opened. At this time, suction is only performed through the suction groove 21. In the later stage of the drying process, the inclination of the supporting rod 4 increases. At this time, the branch pipe connecting the connecting pipe 7 and the telescopic hose 6 is opened, and the branch pipe connecting the connecting pipe 7 and the placement rack 2 is closed. At this time, suction is only performed through the suction groove 2 41. Water vapor is discharged through the suction groove 2 41, the supporting rod 4, the limiting rod 5, the telescopic hose 6 and the connecting pipe 7. Since the size of the suction groove 2 41 is smaller than that of the suction groove 1 21, the suction force will be greater when the suction power remains unchanged, and the position of the suction groove 2 41 is closer to the ceramic fiber board than the suction groove 1 21. Therefore, in the middle and late stages when the water vapor content decreases, the suction effect of the suction groove 2 41 is better.

[0052] It should be noted that the rotation requirement of the limit rod 5 is met by the design of the telescopic hose 6 .
