Abstract

Abstract An apparatus for dissolving a solid (especially chlorine solids) in a liquid has an inlet line (16) to and a return line (20) from its tank (12) in which a tubular and apertured cartridge (74) contains the solids to be dissolved. The tank end portion (34) of the return line is inserted an adjustable depth into the tank (12) allowing adjustment of the water flow across the solid to be dissolved and hence of the rate of dissolution of the latter. The intake line (16) has a connector (48) a tubular part of which extends into the liquid line (22) and has an opening (50) facing upstream, and analogously a connector (52) of the return line (20) has an opening (54) facing downstream. A hand operable valve (56) and a flow meter (58) are connected in-line with the tank in the intake line (16). The tank end portion (68) of the intake line (16) extends downwardly into the tank and is encircled by a vertically movable pipe (70) which can rest on the bottom of the tank (12), and the portion (68) has at least one hole below the level of the top of the encircling pipe (70) for venting air from the line. To allow convenient recharging of solids to the tank (12) a screwed lid (94) of an orifice (78) to the tank may be arranged to be rotated by the shaft of a tool exerting a couple about an axis transverse both to that of the shaft and of the lid. The arrangement shows readily adjustable and controllable continuously operable dissolution of solids, especially chlorine solids for swimming pools, without the use of an additional power source.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 124 words
An apparatus for dissolving a solid in a liquid flowing in a liquid line having a tank for holding the solid to be dissolved; an intake line for connecting the liquid line in fluid communication with the tank; and a return line for connecting the tank in fluid communication with the liquid line characterised in that ' an_intake connector (48) terminating the liquid line end of the intake line (16) extends into the liquid line (22) and has an opening (50) facing upstream of the flow in that line (22) a return connector (52) terminating the liquid line end of the return line (20), extends into the liquid line (22) and has an opening (54) facing downstream of the flow in that line (22).
Claim 2
Independent Claim 124 words
An apparatus for dissolving a solid in a liquid flowing in a liquid line having a tank for holding the solid to be dissolved; an intake line for connecting the liquid line in fluid communication with the tank; and a return line for connecting the tank in fluid communication with the liquid line characterised in that ' an_intake connector (48) terminating the liquid line end of the intake line (16) extends into the liquid line (22) and has an opening (50) facing upstream of the flow in that line (22) a return connector (52) terminating the liquid line end of the return line (20), extends into the liquid line (22) and has an opening (54) facing downstream of the flow in that line (22).
Claim 3
Dependent Claim 45 words
An apparatus according to Claim 1 wherein the connectors include a stop flange (92) for fixing them respectively relative to the liquid line (18) and a tubular pipe extending transversely into the water line, the opening being a cutaway from one side of the pipe.
Claim 4
Dependent Claim 55 words
An apparatus according to Claim 1 or Claim 2 wherein there is a hand operable valve (56) connected in-line with the tank (12) for adjusting the flow rate of liquid through the tank; and a flow meter (58) connected in-line with the tank (12) for indicating the flow rate of the liquid through the tank.
Claim 5
Dependent Claim 63 words
An apparatus according to Claim 3 wherein the flow meter comprises a substantially transparent downwardly tapered conduit (60) having an inlet (62) near the bottom of the conduit and an outlet (64) near the top of the conduit, and an indicator (66) in the conduit restable on the inlet (62) and displaceable therefrom by the force of liquid moving through the tank (12).
Claim 6
Independent Claim 82 words
An apparatus according to any one of the preceding claims wherein the tank end of the intake line (16) extends downwardly into the tank (12) and a pipe (70) extends substantially vertically in use from adjacent the bottom of the tank (12) to adjacent the top of the downwardly extending portion (68) of the intake line and encircles the said portion (68), the pipe (70) being vertically movable about the portion (68) and being restable on the bottom of the tank (12).
Claim 7
Dependent Claim 27 words
An apparatus according to Claim 5 wherein the portion (68) has at least one hole in it at a level below the top of the pipe (70).
Claim 8
Independent Claim 84 words
An apparatus according to any one of Claims 1 to 6 which is for dissolving chlorine tablets in water, wherein a cartridge for the tablets (36) is a pipe (74) restable on the bottom of the tank (12) the pipe (74) having a plurality of apertures (76) along its length of the pipe, the tank (12) having an orifice (78) registering with the top of the cartridge pipe (74) whereby chlorine tablets can be placed into the cartridge pipe (74) through the orifice (78).
