My invention relates to material collecting and conveying systems, and particularly to floor sweep systems as used in grain elevators and the like.
One of the objects of my invention is to provide an eflicient automatic means for conveying and disposing of floor dust and sweepings.
Another object of my invention is to prsystem requiring a minimum of power for operation.
Another object of the invention is to arrange for the automatic operation of the ap paratus and to make unnecessary the action of an attendant in causing operation.
A further object of the invention is to prevent clogging of the apparatus with the material being handled.
Referring in general to the drawings, Fig. 1 is a perspective sectional elevation of one hopper and conveying ducts;
Fig. 2 is a plan of a section of the system showing three hoppers; and
Referring more in detail to the drawings, 1 is the floor, 2 a grated opening therein, 3 a converging hopper for receiving sweepings or other material. A trap valve a mounted on shaft 5 closes the lower opening in hopper 3 and opens into a compartment 5 which has an orifice 7 openin into conveying duct This duct is open to the atmosphere at one end 9 and communicates at the other end 10 with conveying header 11. A member 12 is located. in duct 8 below the opening 7 to receive the material falling from compartment (3. Dampers 13 and 14 are mounted in ducts 8 and 11 respectively, on a shaft 15. Trap valve alis balanced on shaft 5 by a count-en weight 16, so that counterweight 16 exerts a greater closing pressure on trap valve 4 when it is in closed position than when it is in open position. Cranks 17 and 18 are mounted on shafts 5 and 15, respectively, and are connected by link 19. Conveying header 11 is under reduced pressure from a fan (not shown) connected at 20.
In operation, sweepings or material is de- 1926. Serial No. 102,334.
posited into hopper 3 through opening 2. l Vhen a sufficient amount has collected to overbalance counterweight 16 trap valve 4 will open and drop material through opening 1 into compartment 6, wherethe side pressure of material is suiiioient to maintain trap valve at in open position against the closing pressure of counterweight 16 as counterweight 16 has been raised to a position approaching a vertical line through its axis of rotation, shaft 5.
Rotation of shaft 5 by valve 4 through link 19 and cranks 17 and 18, causes rotation of shaft 15, which opens damper 13 and closes damper 14. [is conveying header 11 is under reduced pressure, the opening of valve 13 subjects duct 8 to an unbalanced pressure condition so that air is drawn into open end 9 of duct 8 and passes over and under member 12. The closing of valve 14 diverts the entire suction action of conveying header 11 to duct 8. The material which has dropped into compartment 6 through trap valve l will pass through opening 7 to member 12 where. it will pile up until it closes opening 7 so that no more material can pass down onto member 12 except as material is removed from the pile on member 12, thus preventing the material clogging duct 8. As the air is drawn through duct 8 from open end 9, it will convey material from the pile under opening 7 along member 12 to its end where the material will be dropped into the blast of air entering duct 8 under member 12, and will be carried into exhaust header 11 and to aseparating device (not shown) where the material will be separated from the air and deposited and the air will pass to the fan.
Valve 1 and dampers 13 and 14 are then restored to normal position by counterweight 16, the entire. operation being automatic.
It Will thus be seen that the discharging operation of a given hopper will close damper 14, thus shutting oil the exhaust to all hoppers farther from the fan. This makes the full exhaust available for the operating hopper, insuring a swift and effective removal of the material deposited therein. As a. consequence a much smaller motor is reveying system of the same number of charging points. Any number of hoppers may be employed, the number even being 1ncreased after the original installation without increasing the motor size because of the independent operation as described.
It is understood that changes and modifications may be made without departing from the spirit of the invention.
