The utility model discloses an injecting paste material filter-pressing effect simulating device which comprises a pressurizing member and a pressure container, wherein the pressurizing member is communicated with the pressure container through an air tube; a water filtering assembly, through which only water can pass, is arranged at the bottom of the pressure container; and a water discharge port is formed in the bottom of the water filtering assembly. By utilizing the injecting paste material filter-pressing effect simulating device, the filter-pressing effect of an injecting paste material under different injection paste pressures can be simulated.
