Abstract

The invention discloses a non-touching slurry pulse destructor in the high-speed paper flow transmitting system, which comprises the following parts: air chamber, elastic rubber diaphragm, two-segmented slurry pipe connecting rapid-expanding rectangle slurry-stable pipe, wherein the cross-sectional area of rapid-expanding rectangle slurry-stable pipe is larger than slurry pipe's; one end of rapid-expanding rectangle slurry-stable pipe is closed and the other end connects air chamber; the elastic rubber diaphragm is set between rapid-expanding rectangle slurry-stable pipe and air chamber, which connects inlet and outlet pipe separately. The invention adds rectangle slurry-stable pipe to increase bulk, which can control action according to real working condition due to air chamber.

Description

technical field

[0001] The patent of the present invention relates to the field of pulping and papermaking equipment and technology, in particular to a pulp flow pulse reduction device, in particular to a non-contact pulp flow pulse reducer for a high-speed paper machine flow delivery system. Background technique

[0002] In order to prevent the pulp flow entering the headbox from having pressure or speed pulses, the flow delivery system of the high-speed paper machine must consider eliminating the pulses in the pulp flow. The work has little effect, because the air layer above the pulp in the headbox can inhibit the pulse, but on a high-speed paper machine with a fully enclosed full-flow or hydraulic headbox, the pulse of the pulp flow will cause paper web quantification. fluctuations. The pulp flow pulse in the paper machine flow delivery system is mainly caused by the pulse generated by the pump and the rotor screen. Secondly, the air accumulatio...
