Field of the Invention The present invention relates to an apparatus for cleaning a filtrate belt used for removing liquid from a wet material layered on the surface of a filtrate belt through the filtrate belt, and particularly to cleaning a shower pipe constituting the cleaning apparatus. Regarding the mechanism.

[0002]

2. Description of the Related Art The above-mentioned filtrate belt is used, for example, when forming a panel by forming a cement kneaded material on the belt surface or when forming wet paper by forming wet pulp. These wet cement kneaded materials and wet materials such as wet pulp are layered on one surface of a filtrate belt, filtered and dewatered from the other surface of the belt, and subjected to a drying process to produce a cement panel or paper. .

In the operation of the filtrate belt, a washing device for preventing the clogging is indispensable. As the washing device, a shower pipe is provided laterally in the short width direction of the filtrate belt which can run endlessly. Washing is performed by spraying a washing solution toward the surface of the filtrate belt from a number of washing solution spray nozzles attached in the longitudinal direction of the pipe wall, and then the wet solution is circulated to the layered portion.

However, in the above-described cleaning apparatus, continuous use may cause nozzle clogging,
There is a problem that cleaning ability is greatly reduced. When this clogging grows and solidifies, the nozzle must be replaced,
Operation will be stopped.

[0005] The clogging is caused by the fact that when the cleaning liquid is sprayed from the nozzle, the adhered substance is scattered from the filtrate belt and enters the nozzle orifice, or when the cleaning liquid is continuously passed through the nozzle orifice. This is caused by impurities such as water scale being deposited on the inner surface of the inlet of the injection port.

Conventionally, as means for preventing the nozzle from being clogged, a shower pipe provided with a brush at the tip of a rod is inserted and placed in a shower pipe. Usually, the tip provided with the brush is placed at the end of the nozzle row. A method has been adopted in which the inner surface of the pipe wall of the shower pipe is cleaned by placing the rod at a position where it does not interfere with the nozzle, and reciprocating the operator in the axial direction of the shower pipe with the rod base end as necessary.

However, the above-mentioned method in which the brush reciprocates when necessary by the operator not only requires labor, but also lacks the reliability of cleaning, and it is difficult to always stably operate the nozzle.

According to the present invention, it is possible to appropriately perform cleaning of the inner peripheral surface of the shower pipe, particularly the inner peripheral surface of the nozzle opening at the inner peripheral surface of the pipe in the cleaning apparatus.

[0009]

According to the present invention, a plurality of cleaning liquid jet nozzles are attached to a pipe wall of a shower pipe along a longitudinal direction so that the cleaning liquid supplied into the shower pipe is jetted outward through the nozzles. Related to a cleaning device.

A rotary brush is provided in the shower pipe as a nozzle cleaning means in the above-mentioned cleaning apparatus, which is rotatably driven by a motor provided at the end of the pipe.

The brush tip of the rotating brush is disposed so as to be in sliding contact with the inner surface of the cleaning liquid injection nozzle of the cleaning liquid injection nozzle which is opened at the inner peripheral surface of the pipe wall of the shower pipe so as to rotate.

A motor is controlled so that the rotating brush is intermittently driven to rotate, and the rotation causes the bristle tips of the brush to act on the inner surfaces of the inlets of all the nozzles to remove the deposits uniformly and effectively. Cleaning function can be maintained healthy.

[0013] The shower pipe is provided with a discharge device for discharging the deposits removed by the rotating brush together with the cleaning liquid. This discharge device is periodically operated, and the deposits separated into the pipe by the rotating brush are discharged to the outside at a stretch by the liquid pressure of the cleaning liquid, and the deposits re-enter the nozzle to cause clogging, Alternatively, it is possible to effectively prevent a situation in which the liquid is ejected to the filtrate belt through the nozzle.

The rotating brush is composed of a rotating rod extending along the axis of the shower pipe, and a brush material radially protruding from a length of the rotating rod. Is given.
