Description

Technical Field

[0001] This utility model relates to production equipment for hydrophilic composite ceramic fiber materials, and in particular to a multi-stage drying equipment for hydrophilic composite ceramic fiber materials. Background Technology

[0002] After forming and winding, hydrophilic composite ceramic fiber materials require further drying during the production process. Existing drying equipment typically has multiple heating tubes horizontally arranged in the heating area of ​​the oven. The unwinding roller unwinds the material at one end of the oven, and the hydrophilic composite ceramic fiber material passes through the oven and is then wound up by the winding roller at the other end. The arrangement of multiple heating tubes horizontally results in a long oven with a large floor space. At the same time, the evaporated moisture remains inside the oven, reducing the efficiency of material drying. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-stage drying equipment for hydrophilic composite ceramic fiber materials that has a small footprint and high drying efficiency.

[0004] The technical solution to achieve the purpose of this utility model is as follows:

[0005] A multi-stage drying device for hydrophilic composite ceramic fiber materials includes an oven and unwinding rollers and rewinding rollers respectively disposed at both ends of the oven. The oven includes a box body with multiple partitions inside, which sequentially divide the box body into a preheating zone, a main heating zone, and a hot air zone. The main heating zone is provided with multiple heating components, each including multiple heating tubes arranged sequentially from top to bottom. The heating components divide the main heating zone into a left heating zone, a middle heating zone, and a right heating zone. Transition rollers are sequentially disposed in the middle of the left heating zone, the upper part of the left heating zone, the upper part of the middle heating zone, the middle of the middle heating zone, the lower part of the middle heating zone, the lower part of the right heating zone, and the middle of the right heating zone.

[0006] A first hot air duct is provided above the oven. The first hot air duct is provided with a first air inlet and a first air outlet. The first air inlet is connected to the main heating zone, and the first air outlet is connected to the hot air zone. A drying chamber and a first fan are provided inside the first hot air duct. A desiccant is provided inside the drying chamber.

[0007] A second hot air duct is provided below the oven. The second hot air duct has a second air inlet and a second air outlet. The second air inlet is connected to the main heating zone, and the second air outlet is connected to the preheating zone. A second fan is provided inside the second hot air duct.

[0008] With the above structure, the ceramic fiber material is released from the unwinding roller, passes through the preheating zone, the main heating zone, and the hot air zone, and is then wound up by the winding roller. When passing through the main heating zone, the ceramic fiber material sequentially passes through multiple transition rollers, thus sequentially passing through the middle of the left heating zone, the upper part of the left heating zone, the upper part of the middle heating zone, the middle of the middle heating zone, the lower part of the middle heating zone, the lower part of the right heating zone, and the upper part of the right heating zone. This meandering heating path in the main heating zone reduces the length of the main heating zone, thereby reducing the floor space occupied by the drying equipment. Simultaneously, the second hot air duct transfers some heat to the preheating zone to preheat the ceramic fiber material, improving the drying efficiency in the main heating zone. The first hot air duct transfers some heat to the hot air zone and absorbs moisture from the hot air through the drying chamber. This significantly reduces the moisture content in the air of the main heating zone, improving drying efficiency, and also ensures that the hot air blown onto the ceramic fiber material in the hot air zone has a low moisture content, guaranteeing efficient hot air drying of the ceramic fiber material. This invention reduces the floor space occupied by the equipment while ensuring good drying efficiency.

[0009] Preferably, a first air outlet is provided at the first air outlet, the first air outlet is funnel-shaped, and the inner diameter of the end of the first air outlet closer to the first air outlet is smaller than the inner diameter of the end farther away from the first air outlet.

[0010] Preferably, a second air outlet is provided at the second air outlet. The second air outlet is funnel-shaped, and the inner diameter of the end of the second air outlet closer to the second air outlet is smaller than the inner diameter of the end farther away from the second air outlet.

[0011] Preferably, a bent transition tube is provided between adjacent heating tubes in the heating assembly, and the adjacent heating tubes are connected by the bent transition tube, and the heating assembly extends meanderingly from top to bottom. Attached Figure Description
