Tool for disassembling wear-resisting plate of slurry circulating pump

Abstract

According to the tool for disassembling the wear-resisting plate of the slurry circulating pump, when the absorption tower slurry circulating pump normally operates, the wear-resisting plate is scoured and corroded by absorption tower slurry. After long-term operation, a sealing ring is easy to damage, slurry on the joint surface of the wear-resisting plate and the pump cover is easy to permeate, and the wear-resisting plate is difficult to disassemble. The device comprises I-shaped steel (1), round holes are formed in the two ends of the I-shaped steel respectively, a screw rod (6) penetrates through each round hole, the bottom of each screw rod penetrates through a connecting hole of a pump cover and then is in threaded connection with a nut, two sliding rods (2) are fixed to the bottom of the I-shaped steel, and the sliding rods (2) are in threaded connection with the nuts. The two sliding rods penetrate through through holes in a pressing plate (4) to be in sliding fit with the pressing plate, pressing blocks (5) are fixed to the two sides of the bottom of the pressing plate respectively, and a jack (3) is fixed to the center of the upper portion of the pressing plate. The dismounting tool is used for dismounting the wear-resisting plate of the slurry circulating pump.

Description

Technical Field

[0001] The utility model relates to a tool for disassembling a wear-resistant plate of a slurry circulation pump. Background Art

[0002] In thermal power plants, the absorber slurry circulation pump is one of the key equipment in the limestone-gypsum wet flue gas desulfurization technology. The function of the absorber circulation pump is to continuously transport the mixed slurry in the absorber collection pool upward to the spray layer and provide working pressure for the atomizing nozzle. The slurry is atomized as much as possible after passing through the nozzle, so that the small droplets can fully contact the upward flue gas.

[0003] In actual work, it is found that when the absorber slurry circulation pump is operating normally, the absorber slurry will wash and corrode the wear-resistant plate. Long-term operation can easily cause damage to the sealing ring, and the slurry can easily penetrate into the joint surface between the wear-resistant plate and the pump cover, making it difficult to remove the wear-resistant plate.

[0016] Reference Figure 1-Figure 4 A tool for disassembling the wear-resistant plate of a slurry circulation pump, comprising an I-beam 1, circular holes are respectively opened at both ends of the I-beam, a screw 6 is passed through each circular hole, the bottom of the screw passes through the connecting hole of the pump cover and is threadedly connected with a nut, two sliding rods 2 are fixed to the bottom of the I-beam, the two sliding rods pass through the through holes on the pressure plate 4 and slide with the pressure plate, pressure blocks 5 are respectively fixed on both sides of the bottom of the pressure plate, and a jack 3 is fixed to the center of the upper part of the pressure plate.

[0017] The tool for removing the wear-resistant plate of the slurry circulation pump has a nut threadedly connected to the top of each screw.

[0018] The tool for removing the wear-resistant plate of the slurry circulation pump, the pressing block is an arc-shaped pressing block.

[0019] Working principle: When in use, first install the tool, put the pressure plate on the pump cover 7 first, align the pressure block with the wear-resistant plate 8, then thread one end of the screw with two nuts, then pass the screw through the round hole of the I-beam and pick up the I-beam, so that the sliding rod passes through the pressure plate, and the screw passes through the connecting hole at the corresponding position of the pump cover until the I-beam contacts the push rod of the jack and stops, then thread the other end of the screw with a nut to fix the device, put the pump cover flat on the ground, start the jack, and the push rod of the jack is pushed out to press the I-beam. Since the position between the I-beam and the pump cover is limited by the screw, after the push rod of the jack is pushed out, the pressure plate moves down, so that the pressure block presses the wear-resistant plate to achieve the removal of the wear-resistant plate.
