一种用于调节滚塑烘箱内气压的调节装置
摘要：
本发明提供了一种用于调节滚塑烘箱内气压的调节装置，属于滚塑技术领域。它解决了现有烘箱上的排风口排放风量不可调的问题。本用于调节滚塑烘箱内气压的调节装置，包括烘箱和开设在烘箱上端部的排风口，还包括风机和排风罩，所述的风机包括电机、风机罩、开设在风机罩内的内腔和安装在内腔内的风叶，风机罩上具有进风口和出风口，所述排风罩具有通风管道，所述通风管道一端与上述排风口连通，另一端与上述的进风口连通，所述的通风罩上设有能够调节所述通风管道通风量大小的调节结构。本用于调节滚塑烘箱内气压的调节装置具有其排风量可调从而保证烘箱内气压均匀稳定的优点。
摘要（英）：

The invention provides an adjusting device for adjusting air pressure in a rotational moulding oven, and belongs to the technical field of rotational moulding. The adjusting device solves the problem that the wind exhausting quantity of wind exhausting openings in existing ovens is not adjustable. The adjusting device for adjusting the air pressure in the rotational moulding oven comprises an oven, a wind exhausting opening formed in the upper end part of the oven, a fan and a wind exhausting cover. The fan comprises a motor, a fan cover, an inner cavity formed in the fan cover and a blade installed in the inner cavity. The fan cover is provided with a wind inlet and a wind outlet. The wind exhausting cover is provided with a ventilation pipeline. One end of the ventilation pipeline communicates with the wind exhausting opening, and the other end of the ventilation pipeline communicates with the wind inlet. An adjusting structure which can adjust the ventilation quantity of the ventilation pipeline is arranged on a ventilation cover. The adjusting device for adjusting the air pressure in the rotational moulding oven has the advantages that the wind exhausting quantity of the adjusting device is adjustable, and the uniform and stable air pressure in the oven is ensured.
