DISCLOSURE OF THE INVENTION Conventional press filtration device 1
The higher the pressure of the air supplied to the rubber bag 4 is, the higher its filtering capacity becomes. However, in the squeezing filtration device 1, there is a limit to the pressure of the air that can be supplied due to the relationship between the pressure-resistant strengths of the adhesive seal portion of the rubber bag 4 and the joint portion of the air supply pipe 5, and the liquid content of the substance A to be filtered is limited. It was impossible to make the value extremely low.

Further, conventionally, in the processing fields such as dyeing and chemical treatment, a fluid composed of a liquid or a gas body is passed through an object to be processed in a compressed state to bring the object to be processed into contact with the fluid. However, there has been a demand for the appearance of an apparatus capable of promoting dyeing and chemical treatment.

An object of the present invention is to provide a squeezing and fluid passing device which can be applied to a squeezing filter device for squeezing and filtering a liquid content of an object to be filtered to an extremely low state, and can meet the above-mentioned demand. And

In the present invention, the high-pressure fluid is supplied to the inflow region through the fluid supply passage in a state where the object to be treated is filled in the filling space. The supplied high-pressure fluid pressurizes the slidable sliding body to squeeze the object to be processed in the filling space. When the object to be processed contains a liquid component, this liquid component flows through the fluid passage resistor facing the outflow region to the outflow region along with the squeezing, and flows out to the outside via the fluid discharge path. Is discharged. The high-pressure fluid passes through the fluid passage resistance element, the object layer, and the fixed fluid passage resistance element provided on the sliding body against these passage resistances, flows out to the outflow region, and passes through the fluid discharge path. It is discharged to the outside. The high-pressure fluid contacts the object to be processed as it passes through the object layer. When the filling passage is provided, the object to be treated can be filled into the filling space through the filling passage.
