Dynamic bladder tank assembly for surface cleaning apparatus
View Patent ↗The present invention relates generally to an environmentally sensitive mobile cleaning system; and more specifically relates to a holding tank that includes at least one internal bladder for high or ultra-high pressure mobile cleaning apparatus. The holding tank with internal bladder works in combination with a mobile pressure cleaning apparatus for cleaning surfaces while minimizing water usage and containing contaminants before they enter a storm water drain system.
1. A tank and dynamic bladder system comprising:
a tank assembly, said tank assembly including at least four side walls and a bottom panel connected together in a watertight manner, said tank assembly including a tank inlet for transfer of a first liquid into an internal volume of said tank and a tank outlet for transfer of said first liquid out of said tank volume, said tank assembly also including a bladder inlet for transfer of as second liquid into a bladder assembly, said bladder inlet including a bolt ring around said bladder inlet for securing said bladder assembly to said tank assembly, said bolt ring including a metal ring embedded into said bladder assembly, said metal ring including threaded apertures which cooperate with fasteners extending through a respective wall of said tank assembly to secure the bladder to said tank assembly in a sealed arrangement, and a bladder outlet for transferring said second liquid out of said bladder assembly;
said bladder assembly positioned within said tank assembly, said bladder assembly constructed from a flexible material to generally conform to the internal configuration of said tank assembly;
whereby the volume of said first liquid transferrable into said tank assembly and said second liquid transferrable into said bladder assembly are infinitely variable with respect to each other to fill the entire volume of said tank assembly.
2. The tank and dynamic bladder system of claim 1 wherein said tank assembly includes a top panel for enclosing the volume of said tank assembly.
3. The tank and dynamic bladder system of claim 2 wherein said tank assembly inlet and said bladder assembly inlet are integrally formed into said top panel.
4. The tank and dynamic bladder system of claim 2 wherein said bladder assembly includes a bolt ring around said bladder outlet for securing said bladder assembly to said tank assembly, said bolt ring including a metal ring embedded into said bladder assembly, said metal ring including threaded apertures which cooperate with fasteners extending through a respective wall of said tank assembly to secure the bladder to an inner surface of said tank assembly in a sealed arrangement.
5. The tank and dynamic bladder system of claim 2 including a vacuum tank for initially containing collected liquid and debris, said vacuum tank including a filter for removing a portion of said debris from said liquid, said liquid transferred to said bladder assembly.
6. The tank and dynamic bladder system of claim 5 wherein said filter is a filter bag.
7. The tank and dynamic bladder system of claim 5 wherein a vacuum pump is utilized to create a low pressure area within said vacuum tank for drawing said liquid and said debris into said vacuum tank.
8. The tank and dynamic bladder system of claim 7 wherein said liquid and said debris are drawn from a water jet blasting head.
9. The tank and dynamic bladder system of claim 8 wherein said tank assembly includes liquid which is supplied to ultra-high pressure pump for transfer to said water jet blasting head.
10. The tank and dynamic bladder system of claim 2 including a vacuum tank for initially containing collected liquid and debris, said vacuum tank including a filter for removing a portion of said debris from said liquid, said liquid transferred to said tank assembly.
11. The tank and dynamic bladder system of claim 10 wherein said filter is a filter bag.
12. The tank and dynamic bladder system of claim 10 wherein a vacuum pump is utilized to create a low pressure area within said vacuum tank for drawing said liquid and said debris into said vacuum tank.
13. The tank and dynamic bladder system of claim 12 wherein said liquid and said debris are drawn from a water jet blasting head.
14. The tank and dynamic bladder system of claim 13 wherein said bladder assembly includes liquid which is supplied to ultra-high pressure pump for transfer to said water jet blasting head.
15. The tank and dynamic bladder system of claim 1 wherein said tank assembly outlet and said bladder assembly outlet are integrally formed into said bottom panel.
16. The tank and dynamic bladder system of claim 1 wherein said tank assembly outlet and said bladder assembly outlet are integrally formed into at least one of said four side walls.
17. The tank and dynamic bladder system of claim 1 wherein said bladder assembly is constructed from a polymer coated cloth material to add strength to said bladder assembly while still allowing the flexibility required to allow said bladder assembly to substantially conform to the shape of said tank assembly.
18. The tank and dynamic bladder system of claim 17 wherein said polymer is rubber.
19. A tank and dynamic bladder system comprising:
a tank assembly, said tank assembly including at least four side walls and a bottom panel connected together in a watertight manner, said tank assembly including a tank inlet for transfer of a first liquid into an internal volume of said tank and a tank outlet for transfer of said first liquid out of said tank volume, said tank assembly also including a bladder inlet for transfer of as second liquid into a bladder assembly and a bladder outlet for transferring said second liquid out of said bladder assembly, said bladder outlet including a bolt ring around said bladder outlet for securing said bladder assembly to said tank assembly, said bolt ring including a metal ring embedded into said bladder assembly, said metal ring including threaded apertures which cooperate with fasteners extending through a respective wall of said tank assembly to secure the bladder to said tank assembly in a sealed arrangement;
said bladder assembly positioned within said tank assembly, said bladder assembly constructed from a flexible material to generally conform to the internal configuration of said tank assembly;
whereby the volume of said first liquid transferrable into said tank assembly and said second liquid transferrable into said bladder assembly are infinitely variable with respect to each other to fill the entire volume of said tank assembly.
