Embodiment 1

[0037] exist Figure 1 to Figure 4 Among them, 1 is a sieve device for papermaking. The sieve device 1 for papermaking is, for example, a sieve that makes papermaking raw materials flow in from the inside to the outside of the sieve and refines them. A cylindrical sieve 2 for removing dust and foreign matter from papermaking raw materials is Set in slot 3.

[0038] The tank 3 is the place where the paper-making raw materials to be processed are stored, and the tank 3 has an inlet 31 for the paper-making raw materials, a beneficiation outlet 32 ​​and a foreign matter outlet 33 . In addition, the inlet 31 is connected to a raw material supply pipe (not shown), the beneficiation outlet 32 ​​is connected to a raw material discharge pipe (not shown), and the foreign matter outlet 33 is connected to a foreign matter discharge pipe (not shown). In addition, the selected papermaking raw materials discharged from the raw material discharge pipe (not shown) are introduced into other pr...

Embodiment 2

[0050] In addition, the above Figure 1 to Figure 4 The vibration of the vibrating member 5 of the papermaking screen device 1 is vibration in the horizontal direction, which is not limited to this in the invention of the present application, and may also be, for example, Figure 5 to Figure 7 The cylindrical sieve 2 is vibrated in the vertical direction as shown.

[0051] In this embodiment, the vibrating part (vibrator) 6 for giving vibration is located at the top of the groove 3, and the vibrating member 5 is in contact with the upper end surface of the cylindrical screen 2, except that it is the same as the above-mentioned embodiment. So in this embodiment, for the above Figure 1 to Figure 4 The same parts of the above-mentioned screen device 1 for papermaking are assigned the same reference numerals, and description thereof will be omitted.

[0052] In addition, S is a sealing member that seals the groove 3 and the vibrating member 5, and 11 is a vibration absorbing ma...

Embodiment 3

[0054] In addition, the above Figure 1 to Figure 7 The above-mentioned screen device for papermaking is a screen that makes the papermaking raw material flow from the inside to the outside of the screen to refine it, but the invention of the present application is not limited thereto. For example, Figure 8 and Figure 9 As shown, the cylindrical sieve 2 can be vibrated similarly to a sieve in which paper-making raw materials flow in from the outside to the inside of the sieve to separate them.

[0055] That is, the tank 3 for storing papermaking raw materials has an inlet 31 for papermaking raw materials, a refined outlet 32 ​​and a foreign matter outlet 33. The inlet 31 is connected to a raw material supply pipe (not shown), and the refined outlet 32 ​​is connected to the raw material. To the discharge pipe (not shown), the foreign matter outlet 33 is connected to the foreign matter discharge pipe (not shown). In addition, the selected papermaking raw materials discharged...

Abstract

The aim of the invention is to provide a papermaking screen device which realizes the increase of the processing capacity. The papermaking screen device (1) comprises the following components: a tank (3) for receiving a papermaking material, the tank having an inlet (31), a refining outlet (32), a foreign material outlet (33); a cylindrical screen (2) which is provided in the tank (3) and divides the inner part of tank (30) to a primary chamber (3A) and a secondary chamber (3B), wherein the cylindrical screen is open at the upper surface and the base surface and comprises an opening (21) at the external side surface; an agitating member (4) which is provided in the primary chamber (3A) at the inner side of the cylindrical screen (2); and a vibration member (5) contacting the cylindrical screen for vibrating the cylindrical screen in such a range that the cylindrical screen does not contact the agitating member. The inlet (31) and the foreign material outlet (33) face the first chamber (3A), and the refining outlet (32) faces the second chamber (3B).

Description

technical field [0001] The present invention relates to a screen device for papermaking, and particularly relates to a screen device for papermaking that can improve processing capacity. Background technique [0002] Conventionally, for example, there is a sieve provided with rotating blades (stirring member) inside a sieve basket (cylindrical sieve) (for example, refer to Patent Document 1 FIG. 16 ). [0003] Patent Document 1: Patent No. 3190254 Contents of the invention [0004] In this sieve, pressure is generated for the screen basket (cylindrical screen) at the front of the rotating blade (stirring member), and pressure is generated for the screen basket (cylindrical screen) at the rear of the rotating blade (stirring member). ) to form a negative pressure, and automatically carry out the mesh cleaning function of the sieve basket (cylindrical sieve) successively. [0005] However, there is a problem that the papermaking raw material is deposited on the inlet side ...
