Description

Technical Field

[0001] The utility model relates to the technical field of electric kilns, in particular to a box-type electric kiln. Background Art

[0002] An electric kiln is a furnace used to fire ceramics and sculptures or to fuse enamel to the surface of metal objects. It is usually made of bricks and stones and can be made into various sizes according to needs. It can be operated by combustible gas, oil or electricity. Electric kilns are easier to control temperature than kilns using combustible gas and oil.

[0003] Announcement No. (CN208671709U) discloses an electric kiln that can filter and discharge waste gas. The output gear is driven by a motor to rotate, which drives the transmission gear to rotate, thereby causing the shaft to rotate, and then driving the fan blades to rotate, thereby discharging the dust in the box through the ventilation pipe, causing the dust to fall into the water in the water tank, so that the air is purified and discharged through the vent. At the same time, the rotation of the shaft drives the stirring rod to rotate, so that the dust on the inner wall of the ventilation pipe is scraped off by the stirring rod and then falls into the water tank, completing the purification of the waste gas. During the operation of the above-mentioned device, the workpieces need to be stacked on a placement plate for heating, which will result in insufficient heating of the workpieces and needs to be improved.
