ABSTRACT:
A bar screen is primarily intended for use in draining liquid from wood chips and pulp without blocking the bar screen. The area of use is especially a process area, in which cooking and circulation liquid is removed from a pressure vessel when making chemical pulp and paper pulp by continuous method. This type of bar screen is characterized in that behind the filtering gap of the screen bars, there is a flow space in which the liquid flows towards a discharge outlet. By adjusting the flow space, a flow rate of liquid which stops blocking due to accumulation is maintained in the background. The sturdiness of the screen structure is improved by adjustable support taps.
