Title: Improvements in Apparatus for Purifying or Softening Water.
Inventor: WEDDELL EDWARD GASCOIGNE
Filed: 1903-02-19
Granted: 1903-12-31
Abstract: 3970. Weddell, E. G., Chamberlain, J. G., and Player, R. Feb. 19. Water, purifying and softening. - Water is purified or softened by treatment with soda, either with or without lime. The supply pipe a is fitted with a valve a<1>, controlled by a float in connection with the chamber c, and delivers water to a water - wheel d. This discharges into a tank e divided by movable partitions f<1>, f<2>, &c. into compartments, the largest of which, e<2>, discharges directly into a tun-dish h. Where lime is used in the process, the compartment e<3> is divided, and one part of the contents led through a pipe g<1>, to a chamber i, fitted with a stirring- arrangement i<1>, i<2> driven by the water-wheel. The milk of lime, here formed, passes to a tank k, and is mixed with the rest of the water led by a pipe g' from the compartment e<3>. The clarified lime water passes through a pipe g<4> to the tun-dish. The waterwheel may be replaced by or combined with a weir, over which the water flows into the compartments e<1>, e', &c. The compartment e<1> discharges through a pipe g<5>, into the bucket l<1> of an automatic tipper, which is fixed on a lever pivoted at o. When the bucket o is sufficiently full, it discharges into the shoot l<3> and thence to the tun-dish. Simultaneously, the vessel m at the other end of the lever discharges a fixed quantity of soda solution from the cistern n into m<1> and thence by the pipe m<2> to the tun-dish. During discharge, the bucket l' fills from the bucket l<1>, and keeps the tipper down, until the bucket l<1> is empty. Any water remaining in the bucket l<2> drains off through holes in the bottom. A bucket fixed above the bucket l<2> receives the water from the pipe g<5>, while the tipper is down, and discharges to l<1>, on rising. Alternatively, the pipe g<5> may be provided with a valve, which closes when the bucket l falls. Another form of soda distributer consists of a water-wheel, such that, when a bucket is sufficiently full, the wheel rotates through 90‹. This causes another wheel to revolve once, and by means of a crank and link, to empty the bucket m, and re-immerse it in the soda tank n. The water passes from the tun-dish to a feedwaterheater, provided with horizontal baffle-plates and a steam-inlet valve, and thence to a precipitating- tank.
