Description

Technical Field

[0001] The utility model relates to the technical field of ovens, in particular to an oven used for pulping in the paper industry. Background Art

[0002] The drying oven adopts the new energy-saving and environmentally friendly heating technology promoted by the country. It heats the electric heating tube through power supply to generate heat source, which can be directly converted into thermal energy when absorbed by the heated object, thereby achieving a rapid drying effect, shortening the production cycle, saving energy, and improving product quality.

[0003] For example, a paper pulp oven (Announcement No.: CN209568319U) includes an oven body, two dehumidification pipes fixed on the upper surface of the oven body, two sealing doors rotatably connected to the front surface of the oven body, and an air duct fixed on the front surface of the sealing door. The motor in the upper side of the air duct of the device drives the rotating shaft and the fan blades to rotate, so that the hot air above the interior of the oven body can be introduced into the air duct and re-discharged into the lower position inside the oven body, so that the hot air continues to flow from the lower part of the oven body to the upper part, so that the temperature inside the oven body can be quickly increased, thereby improving the efficiency of drying materials, and moisture is discharged from the dehumidification pipe and liquefied on the inner wall of the condenser. The liquid will flow along the inner wall of the condenser under the action of gravity and be discharged to the outside through the guide pipe, thereby preventing moisture from entering the working environment, protecting the working environment, and collecting moisture at the same time.

[0004] When the device is in use, the hot air inside the oven body is exchanged through the air duct. Since the air duct is fixed on the upper surface of the sealed door, it is easy for workers to touch the air duct during operation, which poses a safety hazard. Therefore, we need to propose an oven for paper pulping. Utility Model Content
