Description

Technical Field

[0001] The invention belongs to the technical field of centrifugal pump surface spraying, and in particular relates to a centrifugal pump surface treatment spraying device for automatic liquid replenishment. Background Art

[0002] A centrifugal pump is a common type of powered water pump used to move liquids, such as water or other fluids. It works on the principle of centrifugal force, which increases the kinetic energy of the liquid through the rotating impeller (also called blades), thereby pumping the liquid from one place (such as a well or sink) to another place (such as a water tank or irrigation system). Centrifugal pumps are commonly used in industry, agriculture, municipal engineering, and domestic use.

[0003] During the operation of a centrifugal pump, especially when handling liquids containing particulate matter, the impeller and the inside of the pump casing are susceptible to wear. By spraying wear-resistant materials, the wear resistance of pump components can be greatly improved and their service life can be extended. The liquids in some application environments may be corrosive, such as acidic or alkaline solutions. Applying specific polymers or corrosion-resistant coatings can effectively protect the metal surface of the pump and prevent corrosion damage. At the same time, spraying can improve the smoothness of the inside of the pump and the impeller surface, reduce the friction resistance of the fluid, and improve the efficiency of the pump. Especially for centrifugal pumps running at high speeds, reducing friction losses can save energy and reduce operating costs. Most of the existing spraying operations are done manually, which is inefficient, and because the centrifugal pump is in the shape of a volute, there are places inside that are difficult to spray.

[0015] Through the above technical solution, the second motor can drive the gear to rotate, and the gear can drive the telescopic rod to move downward through cooperation with the rack and extend into the centrifugal pump casing. When the first button touches the protrusion, the first electromagnet is powered off, the second electromagnet is powered on, and the first motor rotates in the opposite direction, so that the first spray block and the second spray block are re-wound on the mounting seat.

[0017] Through the above technical solution, as the expandable spray head rotates and the telescopic rod moves downward, the second spray block will touch the second button on the guide head. At this time, the second electromagnet is powered off and the first electromagnet is powered on to adsorb the second spray block onto the guide head. Subsequently, the guide head moves upward driven by the telescopic rod, driving the second spray block to move to the water outlet of the centrifugal pump casing. At the same time, the guide head is driven to rotate by the third motor, thereby comprehensively spraying the inner wall at the water outlet.

[0018] Furthermore, a second pipe and a third pipe are opened in the mounting seat, the hard pipe, the hose, the second pipe, the third pipe and the first pipe are connected, a plurality of first nozzles are fixedly connected to the second spray block and the first spray block, a hose is connected between the first spray block and the mounting seat, a plurality of second electromagnets are fixedly connected around the mounting seat, and the outer shells of the first spray block and the second spray block are both made of metal iron.

[0019] Through the above technical solution, the first spraying block and the second spraying block can be adsorbed on the mounting seat, so as to perform spraying operation on the inside of the centrifugal pump casing.

[0020] Furthermore, the external spraying mechanism includes a second liquid storage tank, a second liquid pump is fixedly connected to one side of the second liquid storage tank, a second liquid delivery pipe is fixedly connected to the output end of the second liquid pump, a support frame is fixedly connected to the support frame, a fourth motor is fixedly connected to the support frame, a rotating rod is fixedly connected to the output end of the fourth motor, a spray frame is fixedly connected to the rotating rod, an end of the second delivery pipe away from the second liquid pump is fixedly connected to a second rotating joint, the rotating rod passes through and is rotatably connected to the second rotating joint, a plurality of second nozzles are fixedly connected to the spray frame, a third hydraulic rod is fixedly connected to the upper surface of the second liquid storage tank, a support plate is fixedly connected to the upper end of the third hydraulic rod, a stepper motor is fixedly connected to the support plate, and the output end of the stepper motor is fixedly connected to the fixed plate.

[0022] Furthermore, the fixing mechanism includes a cylinder fixedly connected to the fixing plate, the output end of the cylinder is fixedly connected to the second fixing rod, the end of the second fixing rod away from the cylinder is fixedly connected to the first mounting plate, a plurality of connecting rods are fixedly connected to the first mounting plate, the end of the connecting rod away from the first mounting plate is fixedly connected to the second mounting plate, the first mounting plate is fixedly connected to a fourth hydraulic rod, the output end of the fourth hydraulic rod is fixedly connected to a telescopic head, the end of the telescopic head away from the fourth hydraulic rod is rotatably connected to a plurality of pairs of first connecting rods, the end of the telescopic head away from the first connecting rod is rotatably connected to a plurality of pairs of second connecting rods, the first connecting rod and the second connecting rod are arranged in parallel, the end of the second connecting rod away from the telescopic head is rotatably connected to an expansion plate, the expansion plate is rotatably connected to the first connecting rod, the expansion plate penetrates and is slidably connected to the second mounting plate, and the end of the expansion plate close to the second mounting plate is fixedly connected to a third limit block.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention uses a chain conveyor belt, an internal spraying mechanism, a guiding mechanism, an external spraying mechanism and a fixed structure to automate the internal and external processing of the centrifugal pump casing. Workers only need to place the centrifugal pump casing on a positioning seat, which greatly reduces the labor intensity of workers. (2) The present invention uses an internal spraying mechanism to drive the first movable seat and the second movable seat closer together through the first hydraulic rod and the second hydraulic rod respectively, and clamps and fixes the centrifugal pump casing through the friction ring and the positioning cone head, while the deployable spray head extends into the centrifugal pump casing. Then, the first motor drives the rotating shaft to rotate, so that the centrifugal pump casing rotates to a position blocked by the limit frame. At this time, through the action of the second spring and the steel ball, the first sliding ring no longer drives the rotating sleeve to continue rotating, and the deployable spray head rotates and sprays in the centrifugal pump casing. Then, the second motor on the guiding mechanism drives the telescopic rod to enter In the centrifugal pump housing, the deployable spray head touches the second button during the rotation process, thereby de-energizing the second electromagnet and energizing the first electromagnet. Then, the telescopic rod rises to drive the second spray block away from the mounting seat. At the same time, the third motor drives the guide head to rotate, causing the second spray block to rotate, so that the position at the outlet of the centrifugal pump housing can be sprayed, thereby allowing the interior of the volute-shaped centrifugal pump housing to be sprayed in all directions to avoid dead angles; (3) The present invention uses an external spraying mechanism and a fixing mechanism to first fix the centrifugal pump housing through the fixing mechanism, and then remove the centrifugal pump housing from the positioning seat through the cooperation of the third hydraulic rod and the stepper motor, and rotate it into the spray frame, and then drive the spray frame to rotate through the fourth motor to spray the centrifugal pump housing in all directions. Then, the stepper motor drives the centrifugal pump housing to move to the side away from the frame, making it convenient for workers to remove the centrifugal pump housing.

[0056] The working principle of this embodiment is as follows: the driving motor 11 drives the chain plate conveyor belt 3 to rotate, and the chain plate conveyor belt 3 drives the positioning seat 9 to move. The worker places the centrifugal pump housing 10 on the positioning seat 9. When the centrifugal pump housing 10 moves to the inner spraying mechanism 4, the first hydraulic rod 44 and the second hydraulic rod 45 shrink, the first hydraulic rod 44 drives the first moving seat 410, and the second hydraulic rod 45 drives the second moving seat 412 to move, so that the first fixed rod 411 and the friction ring 426 clamp the centrifugal pump housing 10, and then the second hydraulic rod 45 drives the second moving seat 412 to continue to move, so that the fixed shaft 417 drives the deployable spray head 6 to extend into the centrifugal pump housing 10, and the rotating sleeve 425 compresses the first spring 416, and the centrifugal pump housing 10 is started. The first motor 413 is driven, and the first motor 413 drives the rotating shaft 414 to rotate. The rotating shaft 414 drives the deployable spray head 6 to rotate through the fixed shaft 417. The fixed shaft 417 drives the rotating sleeve 425 to rotate through the first sliding ring 419. The friction ring 426 on the rotating sleeve 425 drives the centrifugal pump housing 10 to rotate. When the centrifugal pump housing 10 rotates to be blocked by the limit frame 51, when the fixed shaft 417 continues to rotate, the groove 422 pushes the steel ball 421 to squeeze the second spring 420, so that the first sliding ring 419 is disengaged from the locking between the rotating sleeve 425, so that the rotating sleeve 425 no longer continues to drive the centrifugal pump housing 10 to continue to rotate, and the deployable spray head 6 continues to rotate under the drive of the fixed shaft 417;

[0057] Afterwards, the first liquid pump 47 delivers the paint in the first liquid storage tank 46 to the first pipeline 415 through the first delivery pipe 48 and the first rotating joint 49. The paint then enters the first spray block 65 through the first pipeline 415, the second pipeline 62, and the third pipeline 63, and enters the second spray block 69 through the hose 66 and the hard pipe 68, and finally sprays out through the first nozzle 610 to spray the inside of the centrifugal pump housing 10.

[0058] Subsequently, the second motor 57 drives the gear 58 to rotate, and the gear 58 drives the telescopic rod 55 to move downward through the cooperation with the rack 56 and extends into the centrifugal pump housing 10. With the rotation of the deployable nozzle 6 and the downward movement of the telescopic rod 55, the second spray block 69 touches the second button 520 on the guide head 518. At this time, the second electromagnet 64 is powered off, and the first electromagnet 519 is powered on to adsorb the second spray block 69 onto the guide head 518. Subsequently, the guide head 518 moves upward under the drive of the telescopic rod 55, driving the second spray block 69 to move to the water outlet of the centrifugal pump housing 10, and at the same time, the guide head 518 is driven to rotate by the third motor 522, thereby The inner wall at the water outlet is sprayed comprehensively. Finally, when the first button 513 touches the protrusion 511, the first electromagnet 519 is powered off, the second electromagnet 64 is powered on, and the first motor 413 rotates in the opposite direction, so that the first spray block 65 and the second spray block 69 are rewound on the mounting seat 61, and at the same time, the first sliding ring 419 is driven to rotate through the fixed shaft 417. The second spring 420 on the first sliding ring 419 pushes the steel ball 421 into the groove 422, so that the first sliding ring 419 drives the rotating sleeve 425 to rotate again, and the rotating sleeve 425 drives the centrifugal pump housing 10 to rotate in the opposite direction to avoid being stuck by the limit frame 51 during the conveying process;

[0059] When the internal spraying of the centrifugal pump housing 10 is completed, the first hydraulic rod 44 and the second hydraulic rod 45 are extended to expand the spray head 6; leave the centrifugal pump housing 10, and then, driven by the chain plate conveyor belt 3, the centrifugal pump housing 10 reaches the external spraying mechanism 7;

[0060] The cylinder 81 pushes the second fixing rod 82 to extend, so that the telescopic head 87 enters the centrifugal pump housing 10, and then the fourth hydraulic rod 85 is shortened, so that the telescopic head 87 is close to the second mounting plate 86, and with the cooperation of the first connecting rod 88 and the second connecting rod 89, the expansion plate 810 is opened to fix the centrifugal pump housing 10, and then the third hydraulic rod 710 is extended to lift the centrifugal pump housing 10 off the positioning seat 9, and then the stepping motor 712 drives the fixing plate 713 to rotate, so that the centrifugal pump housing 10 rotates to the spraying frame 78;

[0061] At this time, the fourth motor 75 drives the rotating rod 76 to rotate, and the rotating rod 76 drives the spray rack 78 to rotate. The second liquid pump 72 transports the paint in the second liquid storage tank 71 to the spray rack 78 through the second delivery pipe 73 and the second rotating joint 77, and sprays it out through the second nozzle 79 to spray the outer surface of the centrifugal pump housing 10. Finally, the stepper motor 712 drives the fixed plate 713 to rotate, so that the centrifugal pump housing 10 rotates to the side away from the side plate 2, and the fourth hydraulic rod 85 extends to shrink the expansion plate 810 and contact the fixation of the centrifugal pump housing 10, so that the workers can remove the centrifugal pump housing 10, and the third hydraulic rod 710 is shortened and reset.
