Problems solved by technology

[0003] Existing electric kilns usually use the outer wall formed by stacking refractory stations as the insulation layer, and place the materials to be sintered inside for heating and firing, while the existing refractory bricks usually use solid bricks, which are made of various materials after mixing and sintering , the tightness and firmness of the connection between refractory bricks have become a further bottleneck restricting the performance of the electric kiln. How to connect with the stainless steel layer conveniently is also a problem that technicians want to solve

Abstract

The invention discloses a firm and heat retaining electric kiln, and belongs to the technical field of kilns. The electric kiln comprises a kiln opening, a kiln tail, and a cylinder body located between the kiln opening and the kiln tail; the cylinder body is obliquely arranged and is driven by a transmission mechanism to rotate; the transmission mechanism comprises a motor and a transmission shaft; doors are arranged at the kiln opening and the kiln tail in a hinged mode; the outer part of the cylinder body is a stainless steel layer, the interior of the cylinder body is a protection layer formed by piling refractory bricks, the middle part is a heat preservation layer filled with a heat preservation material, and heating resistance wires are arranged on the inner wall of the protection layer. The electric kiln has the advantages that the structure is firm, the service life is long, the energy is saved, the internal cleaning is convenient, and operation is simple.

Description

technical field [0001] The invention relates to the technical field of kilns, in particular to a strong and heat-retaining electric kiln. Background technique [0002] The electric kiln uses electricity as the energy source, uses electric furnace wire, silicon carbide gang or molybdenum disilicide as the heating element, and relies on the principle of electric energy radiation and heat conduction for firing in an oxidizing atmosphere. Electronic program control is a kind of kiln, and its operation is simple and safe. Good performance, suitable for various workplaces. [0003] Existing electric kilns usually use the outer wall formed by stacking refractory stations as the insulation layer, and place the materials to be sintered inside for heating and firing, while the existing refractory bricks usually use solid bricks, which are made of various materials after mixing and sintering , The tightness and firmness of the connection between refractory bricks have become a further...
