Abstract:
An automated dump sand separator control system comprising, in combination:a solar panel mounted on a vertical support member by at least one adjustable support arm for adjusting the angular position of said solar panel toward a light source; a shunt regulator connected to said solar panel for decreasing the voltage from said solar panel; a rechargeable battery connected to said shunt regulator for providing power to said automated dump sand separator control system; a first timer connected to said battery for controlling the intervals of an operational cycle of said automated dump sand separator control system; a second timer connected to said battery and said first timer for controlling the time duration of each operational cycle from said first timer, said second timer being activated when said first timer times out, said first timer reactivates when said second timer times out; a three-way solenoid valve connected to said second timer for controlling a device connected to said three-way solenoid valve for a time duration from said second timer; a pneumatically controlled normally closed two-way valve connected to said three-way solenoid valve and attached to a well sand separator for dumping material from said well sand separator; and a housing attached to said vertical support member for enclosing said first timer and said second timer in an environmentally sealed compartment.
