Description

Technical Field

[0001] The utility model relates to the technical field of cleaning a pulp baffle plate at a headbox outlet, in particular to a device for automatically cleaning pulp accumulation at a pulp baffle plate at a headbox outlet. Background Art

[0002] The headbox is an important component of the papermaking machine. Its main function is to evenly distribute the pulp and form a stable pulp flow to spray onto the papermaking net, forming wet paper sheets on the net and dehydrating them. A pulp baffle will be installed at the outlet of the headbox to assist the headbox production.

[0003] The pulp baffle can block the pulp, change the flow direction and flow rate of the pulp, make the pulp evenly distributed on the papermaking mesh, reduce turbulence in the headbox, make the pulp flow more smoothly, adjust the liquid level, affect the paper quantity and thickness, and prevent pulp from splashing, keeping the production environment clean.

[0004] When the pulp baffle is in use, pulp will splash on the surface of the pulp baffle. As time goes by, pulp accumulation will occur, which will destroy the uniform distribution of pulp and thus affect pulp production. A Chinese patent (application number: CN202223019150.6) discloses "a device for automatically cleaning pulp accumulation on the pulp baffle at the outlet of the flow box". Water spray pipes are provided on both sides of the pulp baffle. Water is sprayed through the water spray pipes to clean the inside and outside of the pulp baffle, thereby avoiding manual cleaning by the operator. However, if the surface of the pulp baffle is cleaned solely by the impact force of the water flow, the pressure of the punching water flow needs to be increased due to the high viscosity between some pulp and the pulp baffle, so that the water flow has sufficient flushing force. However, when the water pressure is too high, the water flow will splash after being sprayed on the pulp baffle. The higher the pressure, the farther the water flow splashes, resulting in the inability to collect the splashing water flow, which requires a large amount of water resources and leads to waste of water resources.
