US 5,472,674 A · Apparatus for preparing stock wash liquor

Abstract

An apparatus for preparing a stock wash liquor includes a stock liquor container with a stock liquor container comprising a tub-shaped bottom section and a top section which is hermetically mounted on the bottom section and is fitted with an integral suction fan designed to generate an underpressure or partial vacuum in the bottom section. A suction line leads out of the container and into a container of powder. The aim of the invention is to further develop a device of this kind so that stock liquor can be prepared from cleaning agent powder taken directly from its container without producing any dust, and the stock liquor thus prepared stored for feeding to industrial washing or cleaning machines. This is achieved by locating a secondary suction line end inside the stock liquor container at a point which is remote from the point of entry of a primary suction line into the bottom section. In addition, a fresh water line terminates in the container and has a water outlet aperture disposed so that the water is directed onto the stream of powder passing through the suction line. The container also has a stock liquor feed line which is operatively linked to a pump to permit liquor to be pumped from an inlet near the floor of the bottom section and out of the container.

Dependent claims

The combination comprising:

a tub having a lower portion defining a stock liquor tank;
an upper portion sealingly mounted upon said lower portion, said upper portion defining as a housing including an integrated suction blower operable for generating a reduced pressure in said lower portion;
a container for containing dissolvable powder;
a suction line including an opening at one end within said stock liquor tank, wherein said opening is located remote from where said suction line enters said stock liquor tank, another end of said suction line being coupled into said powder container, whereby when said suction blower is operable, said suction line sucks powder from said powder container into said stock liquor tank;
a fresh water line partly located in said stock liquor tank, and having one end portion with a water outlet positioned for directing water onto a stream of powder drawn by said suction line from said powder container into said stock liquor tank;
a pump for having an inlet port for receiving stock liquor from the bottom of said tank, and an outlet port, said pump being operable for pumping stock liquor out of said outlet port;
and
a stock liquor inlet line located within and proximate a base of said stock liquor tank, said stock liquor inlet line having one end connected to the outlet port of said pump, and another end coupled for delivering said stock liquor to a point remote from said lower portion.
