Title: Glass manufacturing processes and apparatus
IPC: C03B3/00
Filed: 1972-12-28
Abstract: 1454502 Feeding batch materials PILKINGTON BROS Ltd 21 Dec 1973 [28 Dec 1972] 59836/72 Heading C1M [Also in Division G3] In an arrangement for automatically controlling the feed rates of two materials to a glass melting tank 11 for the manufacture of glass, the feed rate of the first material is automatically controlled as a function of the deviation in the melt level in the tank from a desired level and the feed rate of the second material is automatically controlled in dependence upon the feed rate of the first whereby the two feed rates will have a predetermined ratio. The two materials comprise batch materials including normal constituents to form glass and "cullet"-including broken glass and glass refuse. The batch material is transported by a conveyer 12 the speed of which is variable by a gear-box 61 the gear ratio of which is adjustable by a motor 10 controlled by batch feed rate control unit 27. The cullet is transported via a weigh belt conveyer 71, conveyer 13 and a channel 14. The conveyer 71 has a weight sensor 74 connected in a retroactive loop including a limit switch control 75 which controls a gate 72 on a hopper 70 outlet, whereby a constant weight of cullet/unit length is ensured. The cullet feed rate is controlled by a unit 26 which controls the speed of conveyer 71 drive motor 73 via a thyristor unit 78. The actual feed rate of cullet is fed back by a tacho 79 to control unit 26 where it is compared with a desired value. The actual feed rate of batch material is fed back by a tacho 65 to control unit 27, where it is compared with a desired value therefor. The molten glass level is sensed by a watercooled reciprocating probe 16. The resistance of the melt between probe 16 and a fixed electrode 17 is used as an actual level signal and fed to a level control unit 25 where it is compared with a desired level value to produce an error signal in a line 35, which is used as a desired value set point by the cullet feed rate control unit 26. A ratio control unit 28 also receives the actual feed-rate of cullet signal from tacho 79 and produces an output which is used as a desired value for the batch feed rate by control unit 27. In one mode of operation the batch feed rate set point is varied automatically only if the deviation of the desired value signal provided by the ratio control unit 28 from the actual batch feed rate is outside higher or lower limits determined by limit switches 50. In another mode it may be continuously adjustable automatically. Alternatively, the output of level control 25 in line 35 may be fed as the desired value for the batch control unit 27 and the ratio control unit output used as desired value for the cullet feed rate. Further, one feed rate control may have an automatically variable set point and the other a manually variable set point.
