Abstract
665,032. Fluid-pressure servomotor-control systems. RUHRCHEMIE AKT.-GES. July 20, 1949 [Aug. 20, 1948], No. 19108/49. Class 135 [Also in Group XIII] In a process for drying or cooling granular material, the material passes inside a container, over an intermediate floor through which gases flow and thence through a discharge opening of variable aperture, the width of this aperture being so controlled through a servomotor system that the layer depth of the material remains constant on the intermediate floor. The apparatus shown consists basically of a container 1 having an intermediate perforated floor 2 and a pipe 6 to admit the drying or cooling gases. The material enters the container through an opening 3 and is discharged through an opening 4 whose diameter is varied by a flap valve 5. Either the weight of the material on the floor 2 or the back pressure produced by the material at a given feed weight is used to control the valve 5 through a servomotor system. As shown in Fig. 4 the gas pressure prevailing under the floor 2 acts on a membrane 18, the back of which is maintained by a spring 19 whose tension is preadjusted according to the desired depth of material. The movement of membrane 18 actuates a throttle valve 11 which from a pipe 12 releases compressed air on to a further membrane 14 which operates, against a spring 13, the valve 5. In a modification the floor 2 is pivoted at one end, supported by a spring at the other end and a connecting link operates the throttle valve 11, the action then being as above. In another modification shown in Fig. 8 .there is secured in the lower part of the container a spring- loaded membrane 21 which is displaced by the weight of the material and acts on a throttle valve 11, the system then being as above described.
