Description

Technical Field

[0001] This utility model relates to ceramic fiber paper production equipment, and in particular to a drying equipment for ceramic fiber paper production. Background Technology

[0002] Ceramic fiber paper needs to be dried after forming and winding during the production process. Existing drying ovens generally use electric heating tubes for heating. Since the electric heating tubes are installed inside the drying oven, when the electric heating tubes are damaged and need to be replaced, the staff needs to open the drying oven door and enter the drying oven to disassemble and install them. The disassembly and assembly process is cumbersome, takes a long time, and has low efficiency in replacement and maintenance. Summary of the Invention

[0003] The purpose of this invention is to provide a drying device for ceramic fiber paper production that allows for easy replacement of electric heating tubes and high maintenance efficiency.

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

[0005] A drying device for ceramic fiber paper production includes a drying oven and unwinding and rewinding rollers respectively disposed at both ends of the drying oven. Two rows of electric heating tubes are disposed inside the drying oven. A mounting base is disposed on one side of the drying oven, and a mounting hole is disposed on the other side. Each electric heating tube includes a connecting portion disposed at one end, a mounting portion disposed at the other end, and a heating portion disposed between the connecting portion and the mounting portion. The electric heating tube extends into the drying oven through the mounting hole. The connecting portion extends into the mounting base, and the mounting portion is threadedly connected to the mounting hole. A first electric connecting piece is disposed at the end of the connecting portion, and a second electric connecting piece is disposed on the side of the connecting portion. A third electric connecting piece for connecting to the first electric connecting piece is disposed at the bottom of the mounting base corresponding to the end of the connecting portion, and a fourth connecting piece for connecting to the second electric connecting piece is disposed on the inner wall of the mounting base corresponding to the side of the connecting portion.

[0006] With the above structure, when the electric heating tube needs to be replaced, after the oven is powered off, the mounting part can be rotated to disengage from the mounting hole, and the electric heating tube can be pulled out. During installation, simply insert the electric heating tube into the oven through the mounting hole, insert the connecting part into the mounting base, and tighten the mounting part so that the first electrical connecting piece of the connecting part connects with the third electrical connecting piece of the mounting base, and the second electrical connecting piece connects with the fourth electrical connecting piece, thereby connecting the electric heating tube to the oven's power system. This utility model can easily and quickly disassemble and assemble the electric heating tube, improving the efficiency of electric heating tube replacement and maintenance.

[0007] Preferably, in order to facilitate the rotation of the mounting part, the end of the mounting part is provided with a handle for rotating the mounting part.

[0008] Preferably, in order to reduce heat loss from the mounting hole during oven operation, a cover plate threadedly connected to the mounting hole is provided inside the mounting hole.

[0009] Preferably, in order to further reduce heat loss from the mounting holes during oven operation, a heat insulation pad is provided on the side of the cover plate facing the mounting part. Attached Figure Description

[0010] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

Two rows of electric heating tubes 4 are disposed inside the drying oven. A mounting base 5 is disposed on one side of the drying oven, and a mounting hole 6 is disposed on the other side. Each electric heating tube includes a connecting portion 7 disposed at one end, a mounting portion 8 disposed at the other end, and a heating portion 9 disposed between the connecting portion and the mounting portion. The electric heating tube extends into the drying oven through the mounting hole. The connecting portion extends into the mounting base, and the mounting portion is threadedly connected to the mounting hole. A first electric connecting piece 10 is disposed at the end of the connecting portion, and a second electric connecting piece 11 is disposed on the side of the connecting portion.
