っている。Conventional stock solution supply devices for this type of screw press include Utility Model Publication No. 53-6134 and Japanese Patent Publication No. 55-16.
There are issues such as No. 758. In Utility Model Publication No. 53-6134, the raw material (undiluted solution) is supplied from a hopper 125 and sent by the screw blade 9, separated into solid and liquid by the filter tube 10, and taken out from the raw material outlet 5. There is. In addition, in the one shown in the figure of Japanese Patent Publication No. 55-16758, two stages of feeding vanes are provided in the P cylinder 1, and the stock solution (raw material) is
Liquid supply hole 3 in the core of the feed shaft and raw material insertion port 6 provided in the furnace cylinder
The P slag is taken out from the end of the F cylinder.

運転しながら行なってもよい。In the stock solution supply device for the screw press configured in this way, the stock solution is supplied to the starting end of the screen drum through the inside of the feed shaft, is pressurized by the feed blade of the feed shaft, and is separated into solid and liquid by the screen drum. , that F
The slag is taken out of the machine from the other end of the screen drum. During this time, the screen drum is rotating, and if it becomes clogged, it can be cleaned and regenerated by a cleaning nozzle provided around the rotating screen drum. This cleaning operation is
It may be carried out in a badge manner, or in the case of a stock solution that is prone to clogging, it may be carried out during filtration operation.

いものである。In addition, the stock solution supplied into the screen drum during this operation is not affected by the rotation of the feed shaft because the supply path is provided at the axial center of the feed shaft, that is, at the center of rotation. Even soft flocs flocculated using a polymer flocculant do not break down and dehydration properties are not impaired.
以下、図面に基づいてこの発明を具体的に説明する。Hereinafter, the present invention will be specifically explained based on the drawings.
