Product Description

  The open flow box is one of the key equipment in papermaking machinery, mainly used to control the speed and uniformity of the pulp going onto the wire. Below is a brief introduction to the open flow box:

  I. Main Features

  1. Structural Features: Open flow boxes typically have a large-volume tank, forming a pulp pit that can stabilize pulp flow and maintain a certain hydrostatic head. The main body is a welded tank lined with stainless steel; the bottom plate and flow path of the pulp spraying port are cast iron parts lined with stainless steel.

  2. Adjustment Function: The entire tank assembly is mounted on independently adjustable height pillars, which in turn are mounted on a set of sliding rails, allowing for adjustment of the flow box's vertical, horizontal, and tilting angles. In addition, open flow boxes typically control the speed of the pulp going onto the wire by adjusting the weir plate or pulp level inside the box.

  II. Scope of Application

  Open flow boxes are suitable for paper machines with medium machine speeds, especially those in the range of 200~450 meters/minute. Its stable pulp flow and adjustable pulp level height effectively control the speed and uniformity of the pulp going onto the wire, thereby improving paper quality and production efficiency.

  In summary, with its unique structure and adjustment functions, the open flow box plays an important role in papermaking machinery.
