Abstract
A drum press for separating liquid from solid substance, the drum press consisting of two different sized, cylindrical, perforated drums rotating one within the other around different centers, between the envelope surfaces of which the liquid is pressed out from the substance being pressed, and the outer drum being provided with non-rotating end plates disposed with requisite clearance in relation to the rotating outer drum. The inner drum provided with a shaft passes through the non-rotating end plates of the outer drum with requisite clearance, and in its shell and in its end plates fixed on the shaft have been made, towards the shell, apertures, through which the liquid that has entered the drum during the pressing operation is enabled freely to flow out from the drum.
Claims5
A drum press for separating liquid from solid substance, said drum press comprising:
- an outer cylindrical perforated drum rotatable by a support means;
- an inner perforated drum rotating within said outer drum and each drum rotating around different centers, so that between the envelope surfaces of the two drums a liquid is pressed out from the solid substance being pressed, said outer drum being provided with non-rotating end plates disposed with requisite clearance in relation to the rotating outer drum, wherein the inner drum is provided with a shaft and with end plates and a shell which passes through the non-rotating end plates of the outer drum with requisite clearance, the inner drum being provided in its shell and in its end plates fixed on the shaft with apertures towards the shell, through which apertures the liquid that has entered the inner drum during the solids substance pressing operation is enabled freely to flow out from the inner drum.
A drum press for separating liquid from solid substance, said drum press comprising:
- an outer cylindrical perforated drum rotatable about a horizontal center by drive wheels contacting the outer periphery;
- an inner perforated drum rotating within said outer drum and each drum rotating around different horizontal centers, so that between the envelope surfaces of the outer and inner drums a liquid is pressed out from the solid substance being pressed, said outer drum being provided with a non-rotating end plate disposed at each end of the drum with requisite clearance in relation to the rotatable outer drum, wherein said inner drum is provided with a rotatable drive shaft and with end plates and a shell which passes through the non-rotating end plates of the outer drum with requisite clearance, the inner drum being provided with apertures in its shell and in its end plates fixed on the shaft and towards the shell, through which apertures the liquid that has entered the inner drum during the solid substance pressing operation is enabled freely to flow out from the inner drum.
