Sprayer filtering system
A filtering apparatus is configured to receive pressurized fluid from a pump. The filtering apparatus has a main inlet, a main outlet, and a filtering branch comprising a first filter. An agitator of a tank from which the pump draws is configured to receive fluid flow from the filtering branch via a proportional valve and an inlet connection. A method of operating a filtering system includes influencing fluid flow from a tank to one or more nozzles via a filtering apparatus; and diverting a portion of the fluid flow through plural filters of a different mesh size back to an agitating mechanism through a lower portion of the tank.
1. A method of applying fluid with a sprayer vehicle comprising a tank supported by a vehicle chassis and a filtering apparatus defining a main inlet, a main outlet, and a second outlet, the filtering apparatus having a filter, the method comprising:
causing fluid flow from an outlet of the tank to the filtering apparatus;
directing a first portion of the fluid flow through the filter and the main outlet of the filtering apparatus to at least one nozzle; and
diverting a second portion of the fluid flow through the second outlet of the filtering apparatus to an inlet of the tank inlet;
agitating liquid in the tank with second portion of the fluid flow.
2. The method of claim 1 , further comprising directing debris along an interior surface of the filter toward the second outlet.
3. The method of claim 2 , further comprising cleaning the interior surface of the first filter with the second portion of the fluid flow.
4. The method of claim 1 , wherein causing fluid flow from an outlet of the tank to the filtering apparatus comprises pumping fluid from the tank to the filtering apparatus.
5. The method of claim 1 , wherein agitating liquid in the tank with second portion of the fluid flow comprises passing the second portion of the fluid flow through a sparge tube within the tank.
6. The method of claim 1 , wherein directing a first portion of the fluid flow through the filter and the main outlet of the filtering apparatus to at least one nozzle comprises directing the first portion of the fluid flow to a plurality of nozzles spaces along a spray boom.
7. The method of claim 1 , wherein directing a first portion of the fluid flow through the filter and the main outlet of the filtering apparatus to at least one nozzle comprises spraying an agricultural field.
8. The method of claim 1 , wherein diverting a second portion of the fluid flow through the second outlet of the filtering apparatus to an inlet of the tank inlet comprises opening a proportional valve between the second outlet of the filtering apparatus and the inlet of the tank.
9. The method of claim 1 , wherein diverting a second portion of the fluid flow through the second outlet of the filtering apparatus to an inlet of the tank inlet comprises passing the second portion of the fluid flow through a second filter.
10. The method of claim 1 , wherein the second filter has a mesh size larger than a mesh size of the filter.
11. A method, comprising:
causing fluid flow from a tank on a sprayer vehicle to at least one nozzle via a filtering apparatus; and
diverting a portion of the fluid flow along a first filter and through a second filter back to an agitator through a lower portion of the tank, the first and second filters having different mesh sizes.
12. The method of claim 11 , further comprising preventing debris from flowing back to the agitator through the second filter.
13. The method of claim 11 , further comprising cleaning an interior of the first filter with the diverted portion of the fluid flow.
