Problems solved by technology

However, in small paper machines installed in offices or corporate premises, etc., the moving speed of the wire is slow, and the paper making speed is much slower than that of a large paper machine in a paper factory.
[0004] Therefore, if a small paper machine adopts a vacuum pump for a large papermaking device installed in a paper factory, the suction capacity of the vacuum pump is excessive compared to the slow papermaking speed of the small paper machine, which makes the suction efficiency worse, sometimes Will affect the paper quality of the product
In addition, small paper machines become larger devices due to the installation of vacuum pumps with excess suction capacity, etc.

Embodiment Construction

[0040] Embodiments of the present invention will be described below based on the drawings. The papermaking apparatus of the present invention constitutes a part of a small paper machine that can be installed in an office. In addition, the above-mentioned paper machine is a waste paper regeneration processing device, which can use waste paper generated in offices as a papermaking raw material, and regenerate waste paper to produce recycled paper.

[0041] Although not shown in the figure, a paper machine as a waste paper recycling apparatus includes a pulp manufacturing apparatus, a deinking apparatus, and a cutting apparatus in addition to a papermaking apparatus. Pulp manufacturing equipment and deinking equipment are installed in the front section of the papermaking equipment. The pulp manufacturing device produces pulp-containing liquid by adding water to waste paper and stirring it, and decomposing the waste paper. The deinking device performs deinking treatment to separ...

Abstract

The invention provides a papermaking device, a paper machine and a papermaking method. The papermaking device comprises: a filtering part (5), having a netting (56), and the netting (56) moves at a prescribed moving speed to make and filter a liquid containing pulp; a dehydrating part (6), located in the filtering part (5 ) and has a dewatering belt (63), the dewatering belt (63) moves at a predetermined speed to dehydrate the filtered pulp liquid; and the suction part (52, 56) passes through the net ( 56) and at least one of the dewatering belt (63) is used to suck the pulp liquid, and the suction part (52, 56) is provided with a suction member (22) and a suction pump (25), and the suction member (22) has a suction port (28 ), the suction pump (25) is used to suction from the suction port (28) with a prescribed suction amount, the suction pump (25) is composed of a hose pump (35), and the hose pump (35) includes a flexible tube (36) and a pressing member (38) for transferring the contents of the flexible tube (36) while pressing the flexible tube (36) toward the discharge side.

Description

technical field [0001] The present invention relates to a papermaking device, a paper machine and a papermaking method. Background technique [0002] Conventionally, a papermaking apparatus is known in which a suction roll is provided in a filtering section or a dehydrating section. For example, in the papermaking device disclosed in Japanese Patent Laid-Open Publication No. 2003-49378, wet paper is formed by making a liquid containing pulp as a paper raw material liquid on a wire mesh made of a wire mesh or the like, and the wire mesh is placed on the outer peripheral surface of the suction roll. During the movement, the vacuum pump connected to the inner space of the suction roller sucks moisture from the wet paper on the net to dehydrate it. [0003] However, the papermaking apparatus described above is a large-scale facility installed in a paper factory. In a large-scale papermaking device, the papermaking speed is usually above 1000 m / min. However, in a small paper m...
