Abstract

A new and improved hydrocyclone roping and wear management system and method for its use are provided. The system includes one or more wireless electronic roping sensors and/or one or more wireless electronic wear sensors disposed in communication with one or more hydrocyclones, along with a wireless electronic controller. The system is capable of wirelessly detecting roping and/or wear conditions within one or more hydrocyclone separators during their operation, communicating electronic data corresponding to the roping and/or wear conditions to an associated hydrocyclone control system, and causing adjustments in controlling operational parameters for the hydrocyclones. The associated method includes steps for wirelessly acquiring roping and/or wear condition data using the wireless electronic controller and delivering the data to the hydrocyclone control system. The system and method provide for improved roping detection and wear maintenance scheduling, and improved adjustment of undesirable roping and wear conditions.

First claim

The invention claimed is:

1. A hydrocyclone management system for a hydrocyclone separator comprising:
a wireless electronic roping sensor communicating with a flow region of said hydrocyclone separator, and being configured to detect normal, transitional and roping conditions within said hydrocyclone separator;
a wireless electronic wear sensor communicating with an internal wear region of said hydrocyclone separator, and being configured to detect a wear condition within said internal wear region;
An electronic wireless controller configured to wirelessly receive electronic data indicative of said normal, transitional and roping conditions transmitted from said wireless electronic roping sensor and being further configured to wirelessly receive electronic data indicative of said wear condition transmitted from said wireless electronic wear sensor, said electronic wireless controller being hand-portable and battery-powered and comprising a magnet configured to provide a magnetic field as a trigger;
wherein the wireless electronic roping sensor comprises a micro-power sensor configured to detect the magnetic field and activate from a dormant standby mode when the electronic wireless controller is placed in close proximity to the wireless electronic roping sensor, and the wireless electronic roping sensor comprises a radio frequency (RF) transmitter configured to enter into a synchronization or linking mode with the electronic wireless controller upon activation;
wherein the wireless electronic wear sensor comprises a micro-power sensor configured to detect the magnetic field and activate when the electronic wireless controller is placed in close proximity to the wireless electronic wear sensor, and the wireless electronic wear sensor comprises a radio frequency (RF) transmitter configured to enter into a synchronization or linking mode with the electronic wireless controller upon activation.

2. The hydrocyclone management system according to claim 1 , further comprising a hydrocyclone control system communicating with the electronic wireless controller, wherein the electronic wireless controller is configured to deliver said electronic data indicative of said normal, transitional and roping conditions and said electronic data indicative of said wear condition to said hydrocyclone control system to cause adjustment of at least one controlling operational parameter of said hydrocyclone separator; the at least one controlling operational parameter being selected from the group consisting of: flow rate, feed pressure, water addition, and on/off Operation of the hydrocyclone separator.

3. The hydrocyclone management system according to claim 1 , wherein said flow region of said hydrocyclone separator is selected from the group consisting of an underflow outlet, and an overflow outlet.

4. The hydrocyclone management system according to claim 1 , wherein said wireless electronic roping sensor and said wireless electronic wear sensor are both battery-powered.

5. The hydrocyclone management system according to claim 1 , further comprising a docking station; the electronic wireless controller being configured to be placed in the docking station; the docking station being configured to communicate with a computer workstation that is configured to control operational parameters of said hydrocyclone separator.

6. The hydrocyclone management system according to claim 1 , wherein said electronic wireless controller is placed in proximity to said wireless electronic roping sensor.

7. The hydrocyclone management system according to claim 1 , wherein said electronic wireless controller is placed in proximity to said wireless electronic wear sensor.

8. The hydrocyclone management system according to claim 1 , wherein said hydrocyclone separator performs a liquid/solid separation.

9. The hydrocyclone management system according to claim 1 , wherein the wireless electronic roping sensor comprises:
a housing; a digital electronics printed circuit board; a shield; an analog printed circuit board within the shield; a piezo element within the shield; and a battery.

10. The hydrocyclone management system according to claim 1 , wherein the wireless electronic roping sensor comprises:
a housing; a battery; an electronic printed circuit board; and the radio frequency (RF) transmitter on the electronic printed circuit board.
