DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spacing adjusting structure in a stock liquid separating apparatus which can easily adjust the concentration of a mixed papermaking stock liquid (stock stock liquid).

[0002]

2. Description of the Related Art Conventionally, in the recycling of waste paper, the waste paper is separated into a raw material for papermaking and white water from a liquid mixture of papermaking raw material liquefied (about 99% of a stock liquid). There are various devices that perform this. Among them, there is a separation device using a self-suction type drum. A plurality of independent flowing water passages separated by a partition plate are formed along the inner peripheral side surface of the drum, and a large number of water passage holes are formed in the peripheral wall of the drum, so that the stock liquid containing the papermaking raw material flows in and out. The drum is rotatably mounted in a water tank, and a pressure difference is generated between the outside and the inside of the drum so that the stock liquid flows from the outside to the inside through the water holes. It is.

In the above apparatus, when the stock liquid flows from the outside of the drum to the inside, the stock liquid passes through the respective flowing water passages and discharges the liquid from the center of the drum to the outside of the water tank. When the liquid material passes through each of the flowing water passages, the papermaking raw material does not pass through the water passage holes of the drum and becomes clogged, and only white water passes through the flowing water passage. The papermaking raw material clogged in (2) and the white water that has flowed into the flowing water flow down under its own weight, so that a negative pressure is generated in the space above the liquid surface, and the papermaking raw material can be attached to the drum surface.

[0004]

However, when a large amount of papermaking material adhered to the drum surface, there was no adjusting mechanism for further concentrating the papermaking material. That is, it was difficult to concentrate to a desired concentration rate.

[0005]

The inventor of the present invention has conducted intensive studies in order to solve the above-mentioned problems. As a result, the inventor has found that the invention allows the stock liquid to flow inward from the outer peripheral surface, and A papermaking material take-out drum formed so that the papermaking material can be adhered to the outer surface thereof, and an auxiliary drum having an outer peripheral surface equivalent to the outer peripheral surface of the papermaking material take-out drum. A part of the papermaking material tank in the outer casing is rotatably provided in a substantially abutting state, and the main gear is fixed to the papermaking material take-out drum and the auxiliary gear is fixed to the auxiliary drum. The main gear and the auxiliary gear are interlocked via a first intermediate gear and a second intermediate gear, and are fixed to the auxiliary gear and the auxiliary gear meshing with the second intermediate gear about the second intermediate gear. The papermaking machine is equipped with a swing lever that can swing the By solving the above-mentioned problem, the distance between the take-out drum and the auxiliary drum can be adjusted by using the distance adjusting structure in the stock liquid separating apparatus, whereby the concentration adjustment can be easily performed in the papermaking raw material mixed liquid (stock liquid). It is.

[0006]

According to the present invention, the second intermediate gear serves as a sun gear, and the auxiliary gear functions as a planetary gear. With the revolution of the auxiliary gear, the distance between the auxiliary drum fixed to the auxiliary gear and the papermaking material take-out drum is increased. The displacement can be obtained not only within the range of the tooth height of the gear and within the range in which the gear can be engaged, but also by using the revolved distance as the displacement, thereby obtaining a larger displacement than within the range of the conventional gear tooth height, As a result, a desired concentration rate can be obtained, and when a large amount of papermaking material adheres to the drum surface, it can be easily further concentrated.

When the auxiliary gear 22 revolves, the distance between the auxiliary drum B fixed to the auxiliary gear 22 and the papermaking material take-out drum A is increased. Displacement L
Is not only within the range of the gear tooth height and within the range in which the gear can be engaged, but also the revolving distance, so that a larger displacement than before can be obtained (see FIGS. 2 and 3). As a result, various concentrations and types of papermaking raw material mixed liquid (stock liquid)
On the other hand, mass processing by accelerating the rotation of both drums,
There is a great advantage that operations such as a desired concentration rate can be efficiently performed. Further, even when a large amount of papermaking material adheres to the drum surface, it can be easily further concentrated.
