Embodiment Construction
[0022] A screen device for papermaking according to an embodiment of the present invention will be described below with reference to the drawings.
[0023] figure 1 Among them, 1 is a screen device for papermaking, and the screen device 1 for papermaking has a tank 2 for accommodating papermaking raw materials. A stirrer 3 is installed in the tank 2 . It is known that the agitator 3 is provided such as protruding toward the outer periphery of the rotor 30, pressurizing the screen 4 described later at the front of the agitator 3, and cleaning the mesh of the screen 4 at the rear of the agitator 3. role.
[0024] The screen 4 is located in the tank 2 and arranged outside the agitator 3, and is made into a cylindrical shape with both ends open.
[0025] like figure 2 , image 3 As shown, the screen 4 is provided with a passage 40 through which the papermaking raw material passes, and the passage 40 on the side facing the agitator 3 is enlarged toward the side facing the agi...

The invention provides a paper-making screen device which can easily disassemble the screen, comprising: a tank for accommodating paper-making raw materials, an agitator arranged in the tank, and a screen located in the tank and arranged outside the agitator , and a partition wall used to separate the screen from the tank, and the tank has: the first chamber located on the outside of the screen and on the side for accommodating paper-making raw materials, the second chamber located on the inside of the screen and where the agitator is located chamber, and the third chamber located on the outside of the screen and on the side for discharging paper-making raw materials. In the first chamber, a paper-making raw material supply path for supplying paper-making raw materials The first discharge passage for the papermaking raw material that does not pass through the screen in the first chamber, the second chamber is connected with the second discharge passage for discharging the papermaking raw material that has not been guided to the third chamber, and the third chamber is connected with the second discharge passage for passing through the screen. The paper-making raw material discharge path through which the selected paper-making raw materials are discharged toward the outside of the tank.
Description
technical field [0001] The present invention relates to a paper-making screen device, in particular to a paper-making screen device which can be easily disassembled. Background technique [0002] The screen device for papermaking is such that the outer cylinder screen and the agitator are respectively located outside the screen basket, between the screen basket and the outer cylinder screen, and the papermaking raw materials pass through the outer cylinder screen and the screen basket twice. And selected person (for example, with reference to Patent Document 1: Japanese Utility Model Publication Publication Real Fair No. 6-40636 ( figure 1 )). [0003] When using a screen device for papermaking, the outer cylinder screen and screen basket may be damaged due to foreign matter contained in the papermaking raw material. Contents of the invention [0004] Therefore, if it is necessary to replace the damaged screen basket and the outer cylinder screen one by one, especially w...
