a steam box

Abstract

The invention discloses a steam box. According to the technical scheme, the steam box is characterized in that the steam box comprises a box body, a conveying roller, a steam pipeline, nozzles and a heater; a feeding end and a discharging end are arranged at the two ends of the box body respectively; the heater, the conveying roller and the steam pipeline are all arranged inside the box body; the nozzles are arranged on the steam pipeline; air supply mechanisms are arranged on the surface of the box body, and the box body is provided with mounting holes allowing the air supply mechanisms to be mounted; each air supply mechanism comprises fan blades and a drive motor, and the fan blades are arranged on the corresponding drive motor; the nozzles are hinged to the steam pipeline.

Description

technical field

[0001] The present invention relates to the field of steam heating equipment, more specifically, it relates to a steam box. Background technique

[0002] Inside the steam box, there is a steam pipe that sprays high-temperature steam through the nozzle, and there are heating and heat preservation equipment such as heating pipes inside, and a conveying roller that can be transported is also set in the steam box.

[0003] In the manufacture of foamed plastic boards, in order to make the initially foamed plastic boards have a better secondary foaming effect, people send the foamed plastic boards into the steam box for heating, so that the foamed plastic boards can Good for foaming.

[0004] However, due to the high pressure of the injection, the high temperature of the steam, and the very high temperature of the area corresponding to the steam ejected from the nozzle, this will cause the softening and deformation of some areas of the foamed plastic plate, result...
