Tubular Electrical Bayonet Furnace Heating Element 1kw

The bayonet-type heating element comprises more than two porcelains which are sequentially strung on a steel bar, wherein a first porcelain is provided with a wiring bar, a resistance band is winded between the first porcelain and a second porcelain; one end of the resistance band is connected with the wiring bar through the first porcelain, and the other end of the resistance band sequentially passes through other porcelains; the porcelains are round and each is provided with a square hole; and the resistance band is winded forming a cylinder. The beneficial effects of the utility model are that, bayonet-type heating elements are connected in parallel so as to ensure that while in use, if a bayonet-type heating element is damaged, the user can directly pull out the damaged element without blowing out the furnace, and a new element is directly inserted into the equipment for use; and the design facilitates the operation of the user, and effectively helps to complete the production.

Summary of the invention

Problem to be solved in the utility model provides a kind of bayonet type heating element, has solved the problem that exists when general heating element is installed, and is convenient to simultaneously change.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the bayonet type heating element, comprise the porcelain piece more than 2, and described porcelain piece is passed rod iron successively; Be provided with the wiring rod in the first porcelain piece; Be wound with resistive band between the first porcelain piece and the second porcelain piece; Resistive band one end connects the wiring rod by the first porcelain piece, and the other end passes all the other porcelain pieces successively.

Further, described porcelain piece is circular and which is provided with the hole.
