ABSTRACT:
A chemical pellet dispensing device for wells includes a housing defining a pellet chamber and having an inclined bottom wall. A pellet dispensing tube which opens through the bottom wall communicates with the well. A false bottom wall maintains the level of pellets within the chamber below the open end of the pellet dispensing tube. A pellet conveying member is movable along the bottom wall between a position below the level of pellets in the chamber for receiving a pellet to a position in registration with the pellet dispensing tube for depositing a pellet therein. The pellet conveying member is driven by a power source actuated in response to fluid flow from the well. A pellet dislodging slip clutch is interposed between the power source and pellet conveying member. A mechanism is provided for adjusting the rate at which pellets are dispensed into the well.
