An eroding assembly for use in water-soluble chemical feeder where a solid chemical material is eroded by water so as to produce a sanitizing solution of dissolved chemical and water having removal components in its structure for ease of cleaning and removal of any undissolved chemical material, particularly the sieve plate and weir.

An insert for a liquid-holding container may include a body comprising a wall, an open top end and a bottom end, and a generally tubular lumen extending from the open top end to the open bottom end. The insert may include a plurality of first openings formed in the wall, the first openings being situated between the top and bottom ends, wherein each of the plurality of first openings defines an area, and wherein the plurality of first openings have substantially the same dimensions. The insert may include one or more second openings formed in the wall, the one or more second openings being situated between the top and bottom ends, wherein each of the one or more second openings defines an area that is greater than the area defined by any of the first openings, wherein the one or more second openings have substantially the same dimensions.

A fluid injection system includes a container and fluid injection device. The fluid injection device includes a housing having a flow tube having an inlet end and an outlet end. A shroud is positioned between the inlet end and the outlet end and has a first end and a second end defining a ramped surface therebetween. The shroud redefines at least a portion of the fluid pathway as a constricted fluid pathway. A diverter port is between the inlet end and the shroud and diverts a portion of the inlet fluid into the container. An injection port is between the shroud and the outlet end and receives product from the container. The first end of the shroud includes a step defining a notch in fluid communication with the diverter port. The second end defines a recess in fluid communication with the injection port.

The insert also may include a plurality of first openings formed in the wall, the first openings being situated between the first and second ends, and each of the first openings defining an area, and one or more second openings formed in the wall, the one or more second openings being situated between the first and second ends, each of the one or more second openings defining an area that is greater than the area defined by any of the first openings, where at least one of the one or more second openings is situated closer to the first end than any of the first openings, and wherein each of the first and second openings is sized to permit the passage of a liquid.

A fluid injection system includes a container, fluid injection device and a fertigation basket. The fluid injection device includes a housing having a flow tube having an inlet end and an outlet end. A shroud is positioned between the inlet end and the outlet end and redefines at least a portion of the fluid pathway as a constricted fluid pathway. A diverter port is between the inlet end and the shroud and diverts a portion of the inlet fluid into the container. An injection port is between the shroud and the outlet end and receives an injection tube. The fertigation basket holds dry product which is dissolved into the container to be drawn out of outlet end via the injection tube.

A sieve-like filter unit, especially for a cartridge-shaped receptacle, which is arranged on a connecting port/connector of the receptacle and is designed to withhold undissolved powder and/or solid particles present in the receptacle, comprising at least two openings each being composed of at least two connected part recesses, wherein each individual opening in its entirety is formed to be extending in a non-linear manner.

A device (1) for mixing, in particular dispersing, includes a housing (2) with at least one inlet (3) and a grinding chamber (13). In addition, the grinding chamber (13) includes a first process region (4) for mixing fed materials, wherein the materials are introducible into the first process region (4) through the at least one inlet (3), and a second process region (5) for diverting the mixture to an outlet (6) as well as a separating device (7) for separating the first process region from the second process region, and a rotor (8) for mixing, in particular dispersing the mixture in the first process region (4), wherein the rotor is drivable by a drive shaft (9). A pump (10) connected upstream is drivable by the drive shaft (9) and materials are feedable by means of the pump (10) into the first process region (4) and the first process region comprises a dispersion volume within the range of 11-501, in a preferred manner of 41-121 and particularly preferred is 61.
