Problems solved by technology

However, large agglomerates can, and often do, interfere with the process by clogging a constriction or knob in the system
Downstream equipment that relies on a steady feed of fine solids from a feed vessel may not receive timely forecasts of reduced or stopped flow through the system, which in turn can lead to unacceptable fluctuations in the size and / or quality of the final product
Also, removing agglomerates from the system can be very difficult and can introduce impurities into the material being processed

Embodiment Construction

[0037] The numerical ranges in this specification are approximations and therefore may include values ​​outside the range unless otherwise stated. Numerical ranges include all values ​​from and including the lower value to the upper value in increments of one unit, provided that there is a separation of at least two units between any lower value and any upper value. As an example, if compositional, physical or other properties, such as, for example, device size, particle size, pore size, etc., range from 100 to 1000, it is meant to explicitly enumerate all individual values, such as 100, 101, 102, etc., and subintervals , such as 100 to 144; 155 to 170; 197 to 200, etc. For ranges containing values ​​less than 1 or containing fractional values ​​greater than 1, one unit is considered to be 0.0001, 0.001, 0.01 or 0.1, as appropriate. For ranges containing single digit numbers less than ten (eg, 1 to 5), one unit is typically considered to be 0.1. These are merely examples of ...

Abstract

Agglomerated fine solids, e.g., agglomerated pellets (2B), that are located within a restricted space or pinch point of a conveyance system (1), and that impede the free-flow of fine solids from one vessel (4) to another vessel (10), are detected and fragmented through the coordinated use of a flow detector (12), breaker plate (8) and press (6). The flow detector (12) senses an interruption or diminishment in the flow of the fine solids and signals and actuates the press (6) which in turn engages and fragments the agglomeration. The breaker plate (8) is sized and configured to trap major agglomerates.

Description

technical field [0001] The present invention generally relates to material unloading and delivery systems. In one aspect, the invention relates to a system for conveying free-flowing fine solids from a first vessel to a second vessel, and in another aspect, the invention relates to a system equipped with means for breaking up agglomerated fine solids clogging the system system. In another aspect, the present invention relates to a method of removing a clog of agglomerated fine solids from a system that transports fine solids from one vessel to another. Background technique [0002] There are many applications where fine solids, such as shot, are unloaded and conveyed using gravity feed systems. One such application is found in cable manufacturing, where polymeric resins are used to make one or more sheaths that protect the conductive core. The resin is typically conveyed to the manufacturing plant in the form of pellets, transferred to holding and / or feed hoppers, and the...
