Definitions
- the present invention generally relates to placement of granular materials. More specifically, the present invention relates to a rotary airlock device used in a system or apparatus that moves and places granulate.
- Sand, gravel and rock are used in a variety of applications for the construction industry. From aggregate base for concrete slabs, to back fill for retaining walls, granular materials, or granulates, are probably the most widely used substance, outside of concrete, in the construction industry. What has been a common problem has been moving the granulate from place to place when a dump truck and/or cranes and mechanical shovels do not have easy access to the worksite.
- vapor barriers are often required in order to provide moisture protection.
- the material of choice for vapor barriers is typically of a size and material that is job-site-specific, and therefore delivered directly from the vendor to a location adjacent to the flatwork in progress. Since the vapor barrier and subsequent granulate installation are the final steps preceding the actual concrete pouring, they are not completed until all other mechanical, electrical lines and footing reinforcement bars have been installed. As such, heavy equipment cannot be driven over the pad (and lines and bars) because the lines and bars (and vapor barrier) would be disturbed. Because of this restriction, the granulate has heretofore been applied manually with wheelbarrows and shovels.
- the process of concrete flatwork usually involves the installation of a perimeter forms for the slab (i.e. within which the concrete would be poured). These perimeter forms also interfere with the use of heavy equipment to load the granulate into the pad. What is needed is a device and method that permits the transfer of granulate into a concrete flatwork pad without disturbing the mechanical and electrical lines, the reinforcing bars, the vapor barrier or the perimeter forms.

Description
- This application is a United States Continuation application of U.S. Ser. No. 17/012,026 filed Sep. 3, 2020 entitled Rotary Airlock device and System for Moving and Placing Granulate, which itself claims the benefit of U.S. Provisional Patent Application Ser. No. 62/896,906 filed Sep. 6, 2019, entitled Rotary Airlock Device for use with an Apparatus for Moving and Placing Granulate Material, the entire contents of which are incorporated by reference herein for all purposes.
- The present invention generally relates to placement of granular materials. More specifically, the present invention relates to a rotary airlock device used in a system or apparatus that moves and places granulate.
- Sand, gravel and rock are used in a variety of applications for the construction industry. From aggregate base for concrete slabs, to back fill for retaining walls, granular materials, or granulates, are probably the most widely used substance, outside of concrete, in the construction industry. What has been a common problem has been moving the granulate from place to place when a dump truck and/or cranes and mechanical shovels do not have easy access to the worksite.
- Another application, namely the construction of concrete flatwork (slabs on grade and the like) typically require a 2- to 6-inch layer of sand, gravel or other granular material underneath a concrete slab. In these applications, a vapor barrier is often required in order to provide moisture protection. The material of choice for vapor barriers is typically of a size and material that is job-site-specific, and therefore delivered directly from the vendor to a location adjacent to the flatwork in progress. Since the vapor barrier and subsequent granulate installation are the final steps preceding the actual concrete pouring, they are not completed until all other mechanical, electrical lines and footing reinforcement bars have been installed. As such, heavy equipment cannot be driven over the pad (and lines and bars) because the lines and bars (and vapor barrier) would be disturbed. Because of this restriction, the granulate has heretofore been applied manually with wheelbarrows and shovels.
- Furthermore, the process of concrete flatwork usually involves the installation of a perimeter forms for the slab (i.e. within which the concrete would be poured). These perimeter forms also interfere with the use of heavy equipment to load the granulate into the pad. What is needed is a device and method that permits the transfer of granulate into a concrete flatwork pad without disturbing the mechanical and electrical lines, the reinforcing bars, the vapor barrier or the perimeter forms.
- A number of improvements have been made to mechanisms for the pumping of sand and gravel. U.S. Pat. No. 6,336,774 to Dunlap describes a portable, self-contained apparatus capable of discharging granulate into hard-to-reach areas, as well as providing assistance in covering vast open areas with granulate in a short time. The apparatus comprises a fully functional truck having a substantially flatbed upon which is mounted a high capacity air compressor. An air compressor, feeder/hopper, pumping device and the hose are provided. The feeder/hopper is configured to receive loads of granulate and then feed the granulate in a consistent manner into the attached pumping device for pneumatic compression into the hose. The hose is stored on a hydraulic or air driven reel which dispenses the hose for quick set-up and retracts it for ease of returning to storage on the truck.
- As it relates to pumps generally, an ongoing problem experienced by placing flowable material, in particular materials like sand and gravel, is the extreme wear and tear these abrasive materials cause to these systems, and the differing sizes of the particulates. These abrasive materials rapidly break down and even destroy the parts of the handling systems and pumps. Additionally, even with various improvements a significant amount of inefficiencies exists in currently available systems. Leaks caused by the wear and tear of various parts of the system reduce significantly the operational characteristics of these systems. Furthermore, when the worksite is very far from where a truck can go, the pumping mechanism require sufficient power to pump the materials through a hose to the worksite.
- Thus, what is needed is an improved pump/rotary airlock device to achieve a significant increase in the efficiencies of the system and reduce occurrence and frequency of equipment wear.
- The following summary of the invention is provided in order to provide a basic understanding of some aspects and features of the invention. This summary is not an extensive overview of the invention and as such it is not intended to particularly identify key or critical elements of the invention or to delineate the scope of the invention.
