Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
The structure of a kind of structural schematic diagram of paper machine vacuum system, moisture trap shown in referring to FIG. 1, FIG. 2 and FIG. 3 is shown
It is intended to and the top view of moisture trap, a kind of paper machine vacuum system is sucked by vacuum for toilet paper production, including felt aspirates water
Case 1, vacuum carrying roller 3 are separately connected, for storing and separating from the vacuum support with the vacuum carrying roller 3 and felt suction box 1
The moisture trap 2 for the gas liquid mixture that roller 3 and felt suction box 1 enter and for the turbine blower to paper machine vacuum suction,
The moisture trap 2 includes that a container opens up on the container for gas-liquid separation and the filtrate pump 4 that is connected with container
Gas liquid mixture import 7 and gas outlet 11, the inner wall of the container be embedded with one layer of air water filter plate 10, the container it is interior
Wall is equipped with the gas-water separation honeycomb duct 9 of helical raised.
The turbine blower is the single stage turbine blower 6 with the area single vacuum Du Xi, the function of the single stage turbine blower
Rate is 280KW.The moisture trap 2 is internally provided with one for detecting the magnetic double level gauge 8 of liquid level.The gas
Separator gas outlet 11 is connected with single stage turbine blower 6 by pipeline, and strainer 5 is equipped on the pipeline.The air water mistake
Filter plate 20 is located at the top of gas liquid mixture import 7, the uniformly distributed hole in 10 surface of air water filter plate.The air water point
