Blasting System with Dual Dispensers from Single Chamber

Patent Number: US 11884480 Grant Date: 2024-01-30 Filing Date: 2020-12-11

Overview

This patent protects a robust tank assembly designed to deliver slurry blasting media from a single reservoir into multiple conical dispensers with precise flow control. Filed on December 11, 2020 and granted on January 30, 2024, the claim set captures an integrated arrangement of drawtubes, cone flanges, conical dispenser chambers, and plumbing that together enable selective mating of drawtube ends to control slurry flow into each dispenser. Inventors based in Houston, TX developed a system that pairs pneumatic actuation (a pop‑up air supply and compressed-air inlet) with mechanical aids (vibrator brackets and spider guides) to keep high‑viscosity slurry moving consistently into each conical cavity and onward to spray equipment. The specification also incorporates pressure-equalizing features, internal accumulators, and a sealed fill assembly to support reliable operation in industrial blast systems. The drafting emphasizes structural relationships—upper shell, head assembly, cone assembly—and alignment of drawtube axes to protect the functional interplay of components.

Key Features

  • Controlled dual (or multiple) dispenser feed from one slurry reservoir via selectively mated drawtubes
  • Spider guides centered on drawtube axes to ensure even slurry movement
  • Pop‑up air supply and vibrator integration for flow assurance
  • Sealed fill ring and fluid lines to spray equipment for robust deployment

This patent advances industrial slurry blasting by improving feed reliability and modular control, benefiting surface‑treatment and manufacturing applications that demand consistent material delivery.

Invention Details

Abstract: A tank assembly. The tank assembly comprises a shell, a plurality of conical dispensers, a plurality of drawtubes, a plurality of drawtube apertures, a slurry reservoir, one or more spray equipment and a slurry mixture. The slurry reservoir comprises a fluid reservoir within the shell of the tank assembly. The slurry reservoir comprises an upper reservoir and a conical dispensers reservoir. The conical dispensers reservoir can comprise a fluid space within the plurality of conical dispensers. each among the plurality of drawtubes comprise a drawtube axis. The plurality of drawtubes comprise at least a first drawtube and a second drawtube.

Summary of the Invention: A tank assembly. Said tank assembly comprises a shell, a plurality of conical dispensers, a plurality of drawtubes, a plurality of drawtube apertures, a slurry reservoir, one or more spray equipment and a slurry mixture. Said slurry reservoir comprises a fluid reservoir within said shell of said tank assembly. Said slurry reservoir comprises an upper reservoir and a conical dispensers reservoir. Said conical dispensers reservoir can comprise a fluid space within said plurality of conical dispensers. each among said plurality of drawtubes comprise a drawtube axis. Said plurality of drawtubes comprise at least a first drawtube and a second drawtube. each among said plurality of drawtubes is configured to enter said slurry reservoir at said plurality of drawtube apertures located in a top portion of said slurry reservoir. each among said plurality of drawtubes are aligned with said plurality of conical dispensers at a bottom portion of said slurry reservoir. each among said drawtube axis is aligned between said plurality of drawtube apertures and a cone flange. each among said plurality of conical dispensers comprise a first diameter and a second diameter. Said first diameter is larger than said second diameter. Said second diameter is at a lowest part of each among said plurality of conical dispensers. Said cone flange connects to said plurality of conical dispensers said lowest part. Said shell comprises an upper shell between a head assembly and a cone assembly. Said plurality of drawtube apertures comprise at least a first drawtube aperture and a second drawtube aperture. Said upper shell comprises an upper shell circumference. at least one among said drawtube axis of said plurality of conical dispensers falls within said upper shell circumference. a lower end of said plurality of drawtubes selectively mate with said cone flange to control a flow of said slurry mixture from said slurry reservoir within said plurality of conical dispensers.
