초록 ▼

The present invention is an improved washout pan and method for using it that automatically induces stress at the materials-pan surface interface to induce release of cement-containing materials by the nature of the construction of the washout pan and its response to being moved from a horizontal to a vertical position. The composition of the invention washout pan is critical to the objects of the invention, in that it is preferably formed of polypropylene in a rotomolding process as a single piece with a general overall shape of a box with a slurry body capacity of from 100 to 300 gallons.

대표청구항 ▼

1. A method for separating a thixotropic, cement-containing, settled slurry body from a washout pan of less than 300 but more than 100 gallons capacity, the method comprising: providing the washout pan comprisinga generally rectangular box shape, rotomolded of polymer to form an open top box with peripheral walls of from 9 to 15 inches high as measured from a top reinforcing rim plate to a bottom most surface, the washout pan having an overall wall thickness of from 0.15 to 0.75 inches;the peripheral walls comprising a lifting section opposed to a bottom section and a right section opposed to a left section, where the lifting section comprises lifting flanges arranged symmetrically about a midline between the lifting section and the bottom section;a first level support floor intersecting the peripheral walls at a substantial elevation from a set of second level support floors so that the settled slurry body covers both the first level support floor and the set of second level support floors, where nine openings are defined in the first level support floor, four corner openings being defined adjacent to corners of the peripheral walls, right and left openings defined respectively adjacent to the right and left sections, a first mass cavity opening being defined adjacent to the lifting section, a second mass cavity opening being defined in a center of the first level support floor, and a third mass cavity opening being defined adjacent to the bottom section, where the first, second and third mass cavity openings are symmetrically arranged about the midline and all the openings are spaced substantially away from each other so that the settled slurry body comprises a structurally connected mass during its separation from the washout pan; andsecond level support walls extending down from all the openings to be sealed at second level support floors equidistant and parallel to the first level support floor;setting the washout pan horizontally to be filled with the slurry body; andlifting the washout pan to a vertical position by way of the lifting flanges, resulting in deformation of highest elevation second level support walls of containers formed about the first, second and third mass cavity openings and detachment of the slurry body from the washout pan. 2. The method of claim 1 wherein a length of the first mass cavity opening has a first length adjacent to the lifting section and has a width normal to that lifting section about one fourth to two thirds of the length of the first mass cavity. 3. The method of claim 2 wherein edges of the second mass cavity opening are parallel to the peripheral walls and have a length about equal to and aligned with that of the first mass cavity opening and with a midline width of the second mass cavity opening equal to its length or a width within ten percent more or less of the length of the first mass cavity. 4. The method of claim 3 wherein the third mass cavity opening is defined adjacent to the bottom section and comprises a generally rectangular shape with a length about equal to that of the first mass cavity opening and has a width normal to the bottom section that is the same width as that of the first mass cavity. 5. The method of claim 4 wherein a separation of opposing edges of the third and second mass cavity openings is equal to a width of the first mass cavity. 6. The method of claim 1 wherein the washout pan contains a slurry body of 4,000 pounds and is adapted to be transported by forks of a forklift horizontally inserted under the washout pan without spilling the slurry body. 7. The method of claim 1 wherein the washout pan contains a slurry body of 8,000 pounds and is adapted to be transported by forks of a forklift horizontally inserted under the washout pan without spilling the slurry body. 8. The method of claim 1 wherein the washout pan contains a slurry body of 4,000 pounds and is adapted to be transported by forks of a forklift horizontally inserted under the washout pan without spilling the slurry body and the washout pan weighs from 40 to 70 pounds. 9. The method of claim 1 wherein the washout box pan contains a slurry body of 4,000 pounds and is adapted to be transported by forks of a forklift horizontally inserted under the washout pan without spilling the slurry body and the washout pan weighs from 50 to 65 pounds. 10. The method of claim 1 wherein a vertical length of the washout pan is from 55 to 65 inches and a lateral width is from 50 to 60 inches. 11. The method of claim 10 wherein a horizontal width of the washout pan is from 50 to 60 inches.
