Description

A microwave drying device for ceramic fiber liners Technical Field

[0001] This utility model relates to the field of ceramic fiber manufacturing technology, specifically a microwave drying device for ceramic fiber linings. Background Technology

[0002] Ceramic fiber is a fibrous, lightweight refractory material with advantages such as light weight, high temperature resistance, good thermal stability, low thermal conductivity, low specific heat, and resistance to mechanical vibration. Therefore, it has been widely used in industries such as machinery, metallurgy, chemical industry, petroleum, ceramics, glass, and electronics.

[0003] Chinese utility model patent CN210374358U, published on April 21, 2020, discloses a ceramic fiberboard dryer, including a drying chamber, microwave generators, a dehumidification mechanism, and a board placement rack. Two microwave generators are respectively arranged opposite each other on the left and right inner side walls of the drying chamber. The dehumidification mechanism includes a hot air blower located on the outer side of the rear side wall of the drying chamber. Several air outlets are provided on the upper side wall of the drying chamber. The board placement rack includes a supporting base plate and several sets of board clamping components. Each set of board clamping components includes a movable clamping frame and a fixed clamping frame. The movable clamping frame includes a first movable horizontal bar and a first vertical bar, and the fixed clamping frame includes a first fixed horizontal bar and a second vertical bar. When using this dryer to dry ceramic fiberboard, the ceramic fiberboards are separated from each other by the respective board clamping components, allowing water vapor located between the ceramic fiberboards to flow out rapidly, thereby further improving the drying efficiency of the ceramic fiberboard.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the existing microwave drying devices can only dry ceramic fiber boards one at a time. Although this method can achieve large-scale drying at once, each insertion and removal of the fiber boards requires manual operation. Furthermore, the dried ceramic fiber boards cannot be quickly removed due to residual heat, which makes automated and continuous drying impossible. Summary of the Invention

[0005] The purpose of this invention is to solve the technical problem that existing microwave drying devices can only dry ceramic fiber boards one at a time. Although this method can achieve large-scale drying at once, each insertion and removal of the fiber boards requires manual operation. Furthermore, the dried ceramic fiber boards cannot be quickly removed due to residual heat, resulting in the inability to automate continuous drying. This invention provides a microwave drying device for ceramic fiber pads.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention relates to a microwave drying device for ceramic fiber pads, comprising a fixed cover; multiple expansion rollers rotatably connected to the fixed cover; a flexible belt tensioned and sleeved on the expansion rollers; multiple placement plates fixedly attached to the outer surface of the flexible belt; a motor fixedly attached to one end of each expansion roller; multiple air intake holes opened inside the fixed cover; a collection groove opened inside the fixed cover communicating with the air intake holes; a negative pressure fan fixedly attached to the fixed cover communicating with the collection groove; and a microwave transmitter fixedly attached to the fixed cover corresponding to the placement plate.

[0008] Furthermore, the placement plate has multiple ventilation holes extending through its top and bottom; the side of the placement plate has placement grooves connected to the ventilation holes.

[0009] Furthermore, the fixing cover is fixedly connected to the corresponding placement plate with a fixing frame.

[0010] The microwave drying device for ceramic fiber liners provided by this utility model has the following beneficial effects:

[0011] 1. This utility model uses an automated production line to drop ceramic fiber liners one by one onto a placement plate. Then, a motor drives an expansion roller and a flexible belt to rotate, causing the placement plate and ceramic fiber liners to flip. The ceramic fiber liners fall onto the placement plate below and then move with the placement plate to the microwave emitter, thereby heating the ceramic fiber liners for microwave drying. Finally, the dried ceramic fiber liners fall out as the placement plate tilts, thus achieving automated drying of ceramic fiber liners and enabling all-weather automated drying.

[0012] 2. This utility model allows the water vapor generated by the ceramic fiber liner after heating to be discharged through the shortest path via the vent holes. Simultaneously, the ceramic fiber liner can be placed in the placement tank for microwave heating and drying. The ceramic fiber liner rotates with the placement plate to the area under the microwave emitter, thus heating and drying the ceramic fiber liner. Alternatively, the ceramic fiber liner can be placed on the upper surface of the placement plate, and as the placement plate rotates, the ceramic fiber liner falls onto the lower placement plate and then moves to the area under the microwave emitter, thus heating and drying the ceramic fiber liner. This achieves automated feeding and drying of ceramic fiber liners. Attached Figure Description

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0021] Please refer to Figures 1-3. A microwave drying device for ceramic fiber liners includes a fixed cover 1; multiple expansion rollers 2 are rotatably connected to the fixed cover 1; a flexible belt 3 is tensioned and sleeved on the expansion rollers 2; multiple placement plates 4 are fixedly attached to the outer surface of the flexible belt 3; a motor 7 is fixedly attached to one end of the expansion rollers 2; multiple air intake holes 8 are opened inside the fixed cover 1; a collection groove 9 is opened inside the fixed cover 1 communicating with the air intake holes 8; a negative pressure fan 10 is fixedly attached to the fixed cover 1 communicating with the collection groove 9; a microwave transmitter 13 is fixedly attached to the fixed cover 1 corresponding to the placement plate 4, and the device is used to dry ceramic fiber liners via an automated production line. The dried ceramic fiber liners fall one by one onto the placement plate 4. Then, the motor 7 drives the expansion roller 2 and the flexible belt 3 to rotate, thereby flipping the placement plate 4 and the ceramic fiber liners. The ceramic fiber liners fall onto the placement plate 4 below, and then move with the placement plate 4 to the microwave emitter 13, thereby heating the ceramic fiber liners for microwave drying. The dried ceramic fiber liners finally fall out as the placement plate 4 tilts, thus realizing automated drying of ceramic fiber liners and achieving all-weather automated drying.

[0022] The placement plate 4 has multiple ventilation holes 5 extending vertically. A placement groove 6 is formed on the side of the placement plate 4, connecting to the ventilation holes 5. The ventilation holes 5 allow the water vapor generated by the ceramic fiber liner after heating to escape via the shortest path. Simultaneously, the ceramic fiber liner can be placed in the placement groove 6 for microwave heating and drying. The ceramic fiber liner rotates with the placement plate 4 to a position below the microwave emitter 13, thus heating and drying the ceramic fiber liner. Alternatively, the ceramic fiber liner can be placed on the upper surface of the placement plate 4, and as the placement plate 4 rotates, it falls onto the lower placement plate 4 and then moves to a position below the microwave emitter 13, thereby heating and drying the ceramic fiber liner. This achieves automated feeding and drying of the ceramic fiber liner.

[0023] The fixed cover 1 is fixedly connected to the placement plate 4 with a fixed frame 11. The fixed cover 1 is raised by the fixed frame 11 so that the dried ceramic fiber pad can be placed down and transferred.

[0024] The fixed frame 11 is equipped with a conveyor belt 12, which can accept the dried ceramic fiber liner and transfer and discharge it, realizing the function of automated material feeding.

[0025] The flexible belt 3 is made of rubber, which makes it low in density. It can deform after the plate 4 is fixed, so it can move smoothly around the expansion roller 2 and can move smoothly in a cycle.

[0026] The motor 7 is detachably fixed to the outer surface of the fixed cover 1, so that when the motor 7 is powered on, it comes into contact with the indoor air for passive heat dissipation, which allows the motor 7 to operate stably for a long time.
