DETAILED DESCRIPTION

[0010] FIG. 1 depicts an example of a heated cleaning solution dilution system 100, according to an aspect of the disclosure. The system 100 is mounted on a printed placard or panel 101, which provides labels that direct where the other components are to be assembled. Among various modes of delivering the system 100 to a user, some options include: [0011] a. delivering the system 100 fully assembled on a roller stand (transport aid, not shown); [0012] b. delivering the system 100 fully assembled with brackets to mount the placard to a wall of a paperboard converting plant, as shown in FIG. 3; or c. delivering the system 100 as one or more boxes of components with the printed placard as an installation aid for the user to assemble the components onto the panel.

[0013] The system 100 also includes first and second cleaning solution mixer apparatus 102, which are connected to the rest of the system by anti-hammer flexible hoses 104. Because heating the cleaning solution requires pushing the cleaning solution through heat exchangers, which present flow resistance, the system 100 also includes first and second circulation pumps 106 for that purpose.

[0014] Duplicated (first and second) components are a theme of the system 100 (and of the system 200, further described below with reference to FIG. 2). Duplicated components make it possible to keep the system in operation while repairing or replacing a worn or damaged component. Shut off valves 108 also enable isolating a component in one part of the system for repair or replacement while maintaining flow through another part of the system.

[0015] The system 100 may receive water at any range of pressures, although a minimum pressure of about 40 psi is preferred. To regulate the pressure of water in the system, a pressure valve 110 is provided at the water inlet. In some embodiments, the pressure valve 110 regulates the water supply to about 40 psi.

[0016] Because it is preferable to prevent cleaning solution backflowing into the water supply, a non-return valve 112 is provided immediately downstream from the pressure valve. Similar non-return valves 112 also are provided downstream from the circulation pumps 106.

[0017] T-joints 114 provide for parallel duplicate flow paths so that a portion of the system may be isolated for service while maintaining operation of the overall system.

[0018] As can be seen from FIG. 1, the panel or placard 101 is marked with labels that instruct a user where to attach the other components of the system 100.

[0019] FIG. 2 depicts an example of an unheated cleaning solution dilution system 200, according to an aspect of the disclosure. Because the unheated system 200 does not require pushing diluted solution through heat exchangers, the circulation pumps 106 and their non-return valves 112 may be omitted from the unheated system.

[0020] FIG. 3 depicts an example of an unheated cleaning solution dilution system 200 that is installed in a paperboard converting plant 300, according to an aspect of the disclosure. By providing the entire system on a single panel 101, the system can readily be installed (e.g., attached to a wall of the plant) for use.

[0021] FIG. 4 depicts a schematic of a paperboard converting plant 400 that incorporates a cleaning solution dilution system 100, according to an aspect of the disclosure. The system 100 receives pressurized water from a supply line 404, and its mixer apparatus 102 use the pressurized water to suck in and dilute cleaning solution from a tote or other reservoir 402 via a suction line or hose 403. The system 100 then delivers the diluted cleaning solution to one or more of the paperboard converters 406a, 406b, 406c, 406d. From the converters, waste cleaning solution goes to a sump 408. The general arrangement of a paperboard converting plant will be familiar to a skilled worker.

[0022] FIG. 5 depicts an example of a cleaning solution mixer apparatus 102, according to an aspect of the disclosure. The apparatus 102 includes a venturi nozzle 502. The venturi nozzle 502 receives pressurized water from a water inlet 504, sucks in cleaning solution from a cleaning solution inlet 508 through a proportioning valve 510, and discharges the mixture of diluted cleaning solution to an outlet 506. The proportioning valve 510 can be throttled to adjust the fraction of cleaning solution that is mixed with the water.
