Application July 22, 1952, Serial No. 300,148
4 Claims. (Cl. 302-15) This invention relates to a mud feeder for oil wells.
In the drilling of oil wells, mud is fed to the well so as to provide a means for removing the drilled-out material. An object of this invention is to provide an improved means for regulating the discharge of dry mud into a water pipe.
Another object of this invention is to provide a mud regulator which can be mounted in conventional hoppers and which will correctly meter the mud discharged from the hopper, and will permit the hopper to be substantially filled with dry mud at one operation and thereby eliminate the need for a constant attendant to feed the mud slowly to prevent clogging.
A further object of this invention is to provide an improved mud feeding device which includes means for admitting metered quantities of air to the mud valve so as to assure an even flow of mud.
With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.
In the drawings:
Figure 1 is a detail side elevation, partly in vertical section, of a feeder for a mud hopper constructed according to an embodiment of this invention,
Figure 2 is a sectional view taken on the line 2-2 of Figure 1,
Figure 3 is a fragmentary sectional view taken on the line 33 of Figure 2,
Figure 4 is a plan view, partly in section, of the air feeder,
Figure 5 is a fragmentary sectional view taken on the line 55 of Figure 2,
Figure 6 is a sectional view taken on the line 6--6 of Figure 3.
Referring to the drawings, the numeral 10 designates generally an elongated tubular housing which is formed of a tubular upper member 11 connected to a tubular lower member 12 by means of a cylindrical coupling member 13. The lower tubular member 12 is formed with a reduced diameter lower end 14 which is threaded into a cylindrical sleeve 15.
The sleeve 15 snugly fits within a cylindrical discharge nipple 16 carried by the lower end of an upwardly flared or substantially conical hopper 17. The nipple 16 of the hopper 17 is mounted within an upstanding coupling nipple 18 carried by a horizontal water conducting pipe 19. The water pipe 19 is formed adjacent the lower end of the hopper 17 with a reduced diameter pipe 20 which forms a nozzle and venturi whereby water under pressure will flow to the left, as viewed in Figure 1, and will thereby form a suction for drawing downwardly into the pipe 19 dry mud which is discharged into the hopper 17.
The lower housing member 12 is provided with a plurality of vertical elongated intake ports 21 which are arranged circumferentially about the housing member 12 and a cylindrical valve member 22 is slidable within the housing member 12. The valve member 22 is adapted to be vertically moved as will be hereinafter described so as to regulate the opening or closing of the intake ports 21. These ports 21 are disposed adjacent the lower small end of the hopper 17 so that the dry mud within the hopper may gravitatingly flow through the ports 21 into the housing member 12.
A horizontally disposed shaft 23 is journalled diametrically across the upper housing member 11 and has secured within the housing member 11 a substantially T fitting 24 which includes an arm 25 extending at right angles to the shaft 23. A connecting link 26 is secured at its upper end to the arm 25 and is secured at its lower end to a diametrically disposed bar 27 which is secured within the upper portion of the valve member 22.
The shaft 23 has an inner spring 28 engaging thereabout which bears against the housing 11 and fitting 24 and a second or outer spring 29 bears at its inner end against the outer side of the housing member 11 and bears at its outer end against a nut or spring tensioning member 30 mounted on the adjacent outer end of the shaft 23. An L-shaped coupling 31 is secured to the opposite end of the shaft 23 and an elongated handle or crank arm 32 is secured to the L 31 and extends upwardly therefrom. The springs 28 and 29 yieldably hold crank arm or handle 32 against a notched keeper bar 33 (Fig. 4) which is fixed to the outer side of the housing member 11. The keeper bar 33 is formed adjacent the opposite ends thereof with stop members 34 which limit the rocking movement of the handle 32. A cap 35 is threaded onto the upper end of the upper housing member 11 and is formed with a top wall 36 having a pair of sector-shaped openings 37 which are diametrically disposed.
A valve plate 38 is pivotally mounted on a pivot 39 and is movable relative to the openings 37 so as to open or close the openings for admission of air through the upper end of the upper housing member 11. A handle 39a extends from the valve member 38 so that this valve member can be readily adjusted to provide for opening or closing of the openings 37.
In the use and operation of this device, the feeder hereinbefore described is firmly set into the hopper nipple 16 and extends vertically and axially upwardly through the hopper 17. The dry mud is then discharged into the hopper 17 and valve member 22 is vertically adjusted to provide for the desired flow of the dry mud into the mixing pipe 19. The force of the water flowing horizontally from the nozzle pipe 20 into the mixing pipe 19 will cause the dry mud to be drawn downwardly into the mixing pipe 19. The rate of flow of the dry mud is controlled by vertical adjustment of the valve member 22 and the adjustment of the air valve member 38.
With a feeder as hereinbefore described, the hopper 17 may be initially completely filled with the dry mud and it will be unnecessary for an attendant to constantly watch the condition of the hopper after the valve members 22 and 38 have been initially set. As a matter of practice the mud is discharged from one hundred pound bags into the hopper 17 and with the use of conventional hopper devices not containing valved suction devices it is necessary for one or more attendants to be constantly watching the flow of the mud so that the mud will move downwardly into the mixing pipe or chamber 19. However, with the device hereinbefore described, the device will operate without constant attendance of the operator and the mud will evenly flow downwardly for mixing with the water discharged from the nozzle pipe 20 into the mixing pipe or chamber 19.
I- do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling Within the purview of the appended claims.
