Definitions

  • FIG.4
  • a portable high pressure tank cleaning apparatus with a linear movable tubular member that is also rotatably and eccentrically adjustably secured to a base.
  • a cleaning head is located on one end of the linear movable member. The linear movability and rotatable adjustability of the member on the base permits the cleaning head to be positioned at different positions in the tank.
  • This invention relates to a high pressure cleaning apparatus and more particularly to a portable and adjustable tank cleaning apparatus that is linearly movable and laterally rotatable to position the cleaning head to different locations so that the head can direct a high pressure stream of fluid against all interior surfaces of a chemical reactor vessel.
  • a hand lance outside the vessel makes it impossible to reach all interior surf-aces within the vessel.
  • a hand lance invariably creates a fog which further hampers the operator from observing the interior of the tank. Hand lances are further difiicult to maneuver and, due to the high pressure system, create an ever-present danger to operating personnel.
  • Numerous safety procedures are necessary with manual operations, such as locking out the agitator motor and panel switch to render the agitators inoperable, connecting an exhaust hose to the tanks prior to cleaning and exhausting the interior thereof for at least twenty minutes to assure that the toxic fumes therein are all exhausted, since such fumes are heavier than air, locking various valves and engaging safety alarms for the sole purpose of protecting operators working within and around the vessel.
  • a manual cleaning operation is eliminated which avoids occupational hazards, health hazards and further eliminates inherent deficiencies of hand operations such as fatigue and carelessness.
  • a portable cleaning apparatus with nozzles is inserted into the tank and programmed for the several desired positions within the tank and operates without operator manipulations, which apparatus effectively cleans all interior surfaces and is further easily manipulated into and out of the tank. Such operation is done pneumatically to eliminate fire hazards.
  • the apparatus is a compact unit employing novel gear reducing means to provide a balanced unit.
  • a portable high pressure cleaning apparatus has a carrier member whose forward portion supports a cleaning head for rotative and longitudinal movement automatically by a programmed means through the several cleaning positions for rapidly and effectively cleaning the entire Wall surfaces, the apparatus within the vessel, as well as the baffles and agitator blades.
  • the high pressure nozzles on the extreme end of the cleaning apparatus are driven through a hollow shaft with gear means keyed thereto such that the rotating nozzles revolved through a predetermined geometric pattern for directing high pressure sprays to all surfaces within the tank effectively cleaning the interior of the tank.

  • the upper end portion of tubular member or carrier member 30 has a threaded union 31 for connection to suitable flexible hose, not shown, which may be connected to a suitable source of fluid or water under pressure.
  • Tubular member 30 has a central bore 32 (FIG. 2) that extends longitudinally therethrough for connecting the hollow threaded union 31 with a bore 33 in housing 34.
  • Housing 34 has journaled therein for rotation a tubular shaft 35 which suitably communicates with passageway 33.
  • Tubular shaft 35 is also journaled for rotation in the housing of gear reducer unit 36, which gear reducer unit 36 is secured via brackets 37 to housing 34.
  • a transmission means 38 Secured to gear reducer unit 36 is a transmission means 38 which has mounted thereon air motive means 39.

  • Air motor 39 receives pressurized air via a conduit 51, which conduit 51 is connected via suitable passageway not shown that extends through tubular member 30, which in turn is connected to conduit 52, which in turn is connected to a suitable air pressure source whereby motor 39 is energized.
  • a drum 55 Shown in FIG. 4 is a drum 55, which drum is layed out in a flattened developed condition.
  • the drum 55 rotates on a shaft 56, which has keyed to it a one-way clutch 57 supporting a spur gear 58.
  • Spur gear 58 meshes with a rack 60 that is connected to the rod end 61 of a piston 62 located within cylinder 63.
  • Actuation of cylinder 63 indexes drum 55 one increment, with such drum being adapted to be indexed 9 times in the example shown for a complete revolution and with additional spaces provided toassure additional controls positions if desired.
  • the respective rows of the drum are in alignment with a plurality of valves V1 through V7, which valves are either manually operable, as by lever arms a through g, or by cams (A through V) which are positioned upon the rotatable drum 55.
  • Such valves V1 through V7 are two positions, direct operated spool-poppet valves spring returned to normal position.
  • the cams are press fitted onto the selected positions of the drum to give the desired sequence of operation, such that as the drum 55 rotates, the cams selectively engage the downwardly projecting stern thereof.
  • a pressure source 65 is connected via control valve 66 and manifold 67 to the respective valve V1 through V7.
  • V1 connects the head end of cylinder 63 via conduit 68 to exhaust
  • valve V2 connects a whistle 70 via conduit 71 to ex haust
  • valve V3 connects the head end of cylinder 22, via conduit 72 to exhaust
  • valve V4 connects the rod end of cylinder 22 via conduit 73 to exhaust
  • valve V5 conmeets the rod end of cylinder 26 via conduit 74 to exhaust
  • valve V6 connects the head end of cylinder 26 via conduit 75 to exhaust
  • valve V7 connects the lower chamber of a control valve or pneumatic timing relay 76 through accumulator T-l via conduit 77 through an annular groove in spool 78 to exhaust.
  • Control valve or pneumatic timing relay 76 is a commercially available relay on the open market, and the one shown is manufactured by Agastat Division, 1027 Newark Ave, Elizabeth, NJ. 07208. Briefly, the application of pres sure at control port 79 actuates motor diaphragm 81, compressing recycle spring 82 and allowing the timing spring 83 to exert pressure on the timing diaphragm 84. The timing diaphragm compresses the air thereabove in chamber 85 which forces air through the restricted variable control orifice 86 as it passes into chamber 87. As the air is exhausted from the timing chamber 85, a spindle 89 follows the movement of the timing diaphragm 84.
  • the spindle 89 actuates spring 90 into its second position shown in phantom lines causing a snap action transfer of the spool 78 to an upper position which connects conduit 91 from valve V7 to conduit 92, which actuates cylinder 63 as to be described.
  • the snap action movement of spring 90 also removes the input pressure to the chamber 80 served by control port 79 allowing the recycle spring 90 to reset the motor diaphragm 81, causing the spindle 89 to reset the output spool 78, and refills the timing chamber 85 through the check valve '93.
  • the cleaning head In the initial operation the cleaning head is held in the retracted position as disclosed by FIG. 1 as by clamp 96 which keeps tubular member 30 fixed relative to tubular support 21 even though no pressure is in the rod end of cylinder 22 which permits the operator to position the cleaning apparatus within the tank.
  • valve V1 Upon securing the cleaning apparatus to the manhole and clamping it into position, the operator then manually depresses valve V1, which action moves the spool valve V1 in an upwardly direction, connecting the pressure source via manifold 67 to conduit 68 for pressurizing the head end of cylinder 63 which indexes the drum 55 via rack 60 to its first position, wherein cam G actuates valve V4 which connects the pressurized source via manifold 67 and conduit 73 to lower end portion of cylinder 22 which assures that the tubular member 30 is in the uppermost position, thereby relieving the pressure upon the clamp 96, thereby permitting the operator to remove such clamp. The operator then manually depresses valve V1, which pressurizes the head end of cylinder 63 which indexes the drum to its second position.
  • cams B and K respectively actuate valves V3 and V5, while deactuating valve V4 such that the pressurized air from the rod end of cylinder 22 is connected to exhaust while pressurized air from source 65 moves via manifold 67 and conduit 72 to pressurize the head end of pneumatic cylinder 22 which moves tubular member 30 downwardly to its lowermost :position, while valve V5 connects the pressurized source with cylinder 26 to pivot the lowermost end portion of the cleaning apparatus to the left (to the position indicated number 1 in FIG. 2). The operator then hooks up the fluid supply hose, not shown, to the upper end portion of tubular member 30 and the operation is now automatically controlled.
  • valve V1 which indexes the drum 55 to the third position, since the pressurized source actuates cylinder 63 via manifold 67 and conduit 68 such that cams C, L and S actuate valves V3, V5 and V7 respectively.
  • Actuation of valve V3 continues to maintain pressurized air at the head end of pneumatic cylinder 22, while valve V5 maintains pressurized air on the left hand portion of control cylinder 26 as viewed in FIG. 4.
  • Actuation of valve V7 by cam S connects the pressurized source to conduit 91 which directs the pressurized air to an accumulator T l, via conduit 77, which in turn provides a time delay and pressurizes chamber 80, the lower portion of control valve 76, which moves motor diaphragm 81 in an upwardly direction to compress spring 82.
  • control valve 76 is a time delay switch such that the air located in timing chamber 85 is forced through valve 86 to the intermediate chamber 87. Such exchange of air continues until substantially all of the air accumulated in chamber 85 is transferred to chamber 87, which thereby continues to move valve stem or spindle 89 in an upwardly direction as seen in FIG.
  • Valve V4 actuated by cam H directs pressurized air from manifold 67 to the lower portion of control cylinder 22 via conduit 73 which retracts tubular member 30, along with the cleaning head to the uppermost position, while valve V5 maintains the control cylinder 26 in its previously conditioned manner which thereby maintains the cleaning head in the left hand portion of the tank, which in FIG. 2 is position number 2.
  • the valve V7 is again actuated, which via conduit 91, pressurized tank T-1, which in turn directs pressurized fluid to the lower portion of control valve 76 exhausting the air out of timing chamber 85 and transferring such pressurized air to chamber 87.
  • valve V2 connects the pressurized source, via manifold 67 and conduit 71 to the whistle 70, indicating the completion of the operation.
  • valve V1 which connects the pressurized source via conduit 68 to pressurize the head end of cylinder 63, which indexes the drum to its eighth position, which disconnects the whistle from the operation and the operator manually depresses lever a of valve V1 which thence indexes the drum to its final position such that cams J and R actuate valves V4 and V6 which in turn retracts the cleaning head to its uppermost position by connecting the pressurized source to the rod end of cylinder 22 and the head end of cylinder 26, permitting the operator to position the mast clamp 96 about the upper end of tubular member 30 and permits him to disconnect the air hose 52 and water hose, not shown, from the cleaning apparatus and to remove such cleaning apparatus from the tank.
