Definitions
- a pump for pumping catalyst and the like comprising: a horizontal baseplate having a hinge end, a middle portion and a reciprocating end, said middle portion of said base plate having means for attaching a pump housing at various locations thereon; a horizontal pumping arm having a hinge end, a middle portion and a reciprocating end, said middle portion of said pumping arm having means for incrementally moving substantially the entire length thereon and attaching thereto a piston rod; a vertical connecting plate having an upper end and a lower end; said lower end being movably connected to said hinge end of said horizontal baseplate and said upper end being movably connected to said hinge end of said horizontal pumping arm; means for moving the reciprocating end of the pumping arm and the reciprocating end of the baseplate alternately toward and away from each other; a pump housing having an inner portion and an outer portion, said pump housing being movably attached to said means for attaching a pump housing to various locations on said baseplate, said pump housing having an inner cylindrical cavity extending from the inner
- FIG. 1 is a perspective view of the pump of this invention.
- FIG. 2 is a view along the line 2--2 of FIG. 1.
- FIG. 3 is a cross-sectional view taken along the line 3-3 of FIG. 1 illustrating the details of the pump mechanism.
- the baseplate 10 has means for attaching a pump housing at various locations therein illustrated by the groove 11 and the plurality of holes 12.
- a vertical connecting plate 13 is shown being movably attached by a pin 14 to the baseplate.
- the upper portion of the vertical connecting plate is movably attached by a pin 15 to a pumping arm 16.
- the pumping arm has means for incrementally moving substantially the entire length thereon and attaching thereto a piston rod illustrated by grooves 17 and 18 in which a locking plate 19 slides.
- the locking plate 19 passes through both grooves and is threaded in the form of a'bolt 20 on the side opposite the adjustment side.
- a wingnut 21 is used to tighten and secure the adjustment when the proper pumping rate is achieved.
- the grooves 17 and 18 are substantially the entire length of the-pumping arm 16.
- the locking plate 19 is adjusted in the grooves by loosening the wingnut and turning knob 22 which turns screw 23. As the screw 23 turns in the threaded pumping arm extension 24, it forces the locking plate 19 along the grooves.
- the locking plate is movably attached to screw 23 at the point 25 by having the rod pass through a larger diameter hole and not by having the locknuts 26 and 27 completely tightened on the locking plate.
- the piston rod 28 is movably connected to the locking plate by a connection piece 29 which has a hole therein and fits around the cylindrical portion of the connecting plate.
- any conventional method may be used for moving the pumping arm toward and away from the baseplate thereby moving the piston up and down in the piston cylinder cavity.
- this mechanism may be a cam 31 which rotates about cam shaft 32 by pushing the rod 33 down. The rod is then forced upward by the spring 34. The rod is in turn connected to the pumping ann pin 35.
- the pump is best illustrated by its cross-sectional view in FIG. 3.
- the pump has a pump housing 36 which is attached by pin 37 in holes 12.
- the pump housing has an intake fitting 3,8 which is hydraulically connected to the intake passage 39.
- the intake passage 39 is hydraulically connected to the bottom inner cylinder cavity 40.
- the hollow piston 41 moves in the inner cylinder cavity and is provided with seals in the fonn of O-rings 42 and 43.
- a discharge passage 44 is connected to the upper part of the inner cylindrical cavity and has a fitting 45 attached thereto. This fitting is in turn connected to a surge tank 46.
- the piston has a hollow portion 47 which extends from the bottom thereof substantially upward into the upper portion of the piston.
- the upper portion of the piston has discharge port 48 which is merely an opening in the piston wall. This discharge port 48 corresponds to the discharge passage 44 in the pump housing. Flow is directed through the pump in one direction by check valves illustrated here by springs 49, 50, and 51 and balls 52, 53, and 54.
- the pump housing is adjusted to the desired holes 12.
- the wingnut 21 is then loosened and knob 22 is turned to move the piston rod to adjust to the proper stroke and thereby effect the proper pumping rate.
- the wingnut 21 is then tightened to insure that the rate remains steady.
- cam 31 turns, it forces the pumping arm 16 up and down with relation to the stationary base plate 10. This movement causes the piston rod 28 to move up and down and consequently the piston 41 to move up and down in the cylinder cavity.
- all of the check valves are closed.
- the ball 52 opens allowing the cylinder cavity to fill with catalyst.
- ball 52 closesthe cylinder cavity and ball 53 opens filling the piston with catalyst.
- Ball valve 54 then opens allowing catalyst to move into the surge tank. As the catalyst fills the surge tank, it exits in a substantially uniform constant rate of flow.
- This pump provides a new method for providing a wide range of pumping rates by simple adjustment.
- a pump for pumping catalyst and the like comprising: a horizontal baseplate having a hinge end, a middle portion and a reciprocating end, said middle portion of said baseplate having means for attaching a pump housing at various locations thereon; a horizontal pumping arm having a hinge end, a middle portion and a reciprocating end, said middle portion of said pumping arm having means for incrementally moving substantially the entire length thereon and attaching thereto a piston rod; a vertical connecting plate having an upper end and a lower end; said lower end being movably connected to said hinge end of said horizontal baseplate and said upper end being movably connected to said hinge end of said horizontal pumping arm; means for moving the reciprocating end of the pumping arm and the reciprocating end of the baseplate alternately toward and away from each other; a pump housing having an inner portion and an outer portion, said pump housing being movably attached to said means for attaching a pump housing to various locations on the baseplate, said pump housing having an inner cylindrical cavity extending from the inner portion of the pump housing to the outer
