Description

Technical Field

[0001] The utility model relates to the technical field of industrial kilns, in particular to a fixing mechanism for a hard ceramic fiberboard heating element. Background Art

[0002] When fixing the resistance belt of the heating element inside a general industrial furnace, porcelain screws are usually used to screw into the fiber cotton blanket lining according to the waveform of the resistance belt. The part left outside the cotton is used to clamp the resistance belt with a porcelain ring. Arranging the porcelain screws in batches according to the waveform can make the resistance belt fit firmly on the surface of the furnace lining.

[0003] When using hard ceramic fiberboard as the furnace lining, the surface hanging heating element is not suitable for fixing with ceramic screws. The hard ceramic fiberboard is relatively hard and there are no elastic pores on the surface for screwing in ceramic screws. Although holes can be drilled directly on the board with a hand drill, the ceramic screws are movable parts in the holes and cannot be used to fix the heating element. Moreover, the position will be fixed after drilling and fixing. If there are problems such as dimensional errors that need to be adjusted, it will be difficult to solve. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a fixing mechanism for a hard ceramic fiberboard heating element, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned objectives, the present invention discloses a rigid ceramic fiberboard heating element fixing mechanism, which adopts a technical solution comprising a rigid ceramic fiberboard, the rigid ceramic fiberboard being the lining of an industrial kiln. The rigid ceramic fiberboard has a sliding groove formed on its side, a connecting groove formed on the sliding groove, a sliding block slidably connected within the sliding groove, a ceramic support head provided on the outside of the connecting groove, the ceramic support head being inserted into the interior of the sliding block, the sliding block and the ceramic support head being fixed to each other by ceramic screws, and a resistance band being wound around the ceramic support head.

[0006] As a preferred technical solution of the present invention, the ceramic support head is I-shaped, with a plug connector provided at one end and a countersunk hole provided at the other end to prevent the resistance band from moving back and forth and falling off.

[0007] As a preferred technical solution of the present invention, a connecting hole is opened in the middle of the sliding block, and the connecting hole is half a light hole and half a threaded hole. The diameter of the light hole matches the diameter of the plug connector. The ceramic support head is plugged into the interior of the sliding block through the plug connector and the light hole. Since the installation is almost a blind operation, the ceramic support head is first plugged into the interior of the sliding block for preliminary positioning, and then fastened with the ceramic screws to facilitate installation operations.

[0008] As a preferred technical solution of the present invention, there is a gap between the plug connector and the threaded head end of the threaded hole to prevent the plug connector from pressing against the thread of the threaded hole during tightening, causing damage to the thread of the threaded hole or the ceramic support head and the sliding block from being able to clamp the connecting groove.

[0009] Compared with the prior art, the beneficial effect of the present invention is that the present invention enables the ceramic support head to have a reliable fixed position on the hard ceramic fiber board 1 by slidingly connecting the sliding block inside the hard ceramic fiber board. Through the design of the sliding groove and the connecting groove, the ceramic support head can slide back and forth on the hard ceramic fiber board, so that it can be adjusted according to actual conditions and has a wider applicability.
