Description

Technical Field

[0001] This utility model belongs to the field of slurry pump technology, specifically relating to an impeller mounting structure for a slurry pump. Background Technology

[0002] Chinese patent application number 202322587636.8 discloses an impeller mounting structure for a slurry pump. By opening a through hole on the pump body corresponding to the connecting shaft, when the connecting shaft rotates, it drives the extension plate and L-shaped baffle to rotate. The light source and photosensitive sensor are both connected to an external power supply. The light source emits light, and the photosensitive sensor is responsible for detecting whether the light emitted by the light source is blocked by the L-shaped baffle and transmitting the signal to an external photoelectric speed detector for analysis and display. This mounting structure enables the impeller to have a structure that facilitates speed detection after installation, making it convenient to measure the speed of the impeller.

[0003] Currently, when installing impellers, workers often need to install the impeller and other parts onto the rear pump cover one by one. During the entire installation process, workers need to lift these parts. Since the mounting holes need to be aligned when installing impellers and other parts, workers have to lift the parts for a long time. These parts are quite heavy. In fact, when installing the protective sleeve and the front pump cover, lifting equipment is needed to lift the bracket and other structures to align the front and rear pump covers. The entire installation process consumes a lot of physical strength for workers, and it is unavoidable to lift the parts during the installation process. Utility Model Content

[0036] As a preferred option, the impeller shaft 12 is rotatably connected inside the bracket 11, and a rear pump cover 13 is fixedly installed at one end of the bracket 11. When installing the impeller, the bearing end of the impeller shaft 12 needs to be fixed, and then the impeller and the impeller shaft 12 are threaded together.

[0037] The electric slide rail, bracket, impeller shaft, rear pump cover, first motor, first hydraulic cylinder, second motor and second hydraulic cylinder in this case are existing technologies. The impeller shaft has the same structure and connection method as those in the cited documents. As long as the electric slide rail, bracket, impeller shaft, rear pump cover, first motor, first hydraulic cylinder, second motor and second hydraulic cylinder meet the requirements of this case, they are all acceptable and not limited to a single model.

[0038] Working principle: All electrical components mentioned in this application are connected to an external power supply and control switch during use. After installation, first check the installation, fixation, and safety precautions of this utility model before use. During use, the user first places the front pump cover over the mounting rod 72 and onto the limiting rod 71, then places the protective sleeve on the front pump cover in the same manner, and then stacks the rear protective plate and mechanical seal in the same way. After all the above structures are placed on the mounting rod 72, the user then installs the baffle 74 on the mounting rod 72 using the studs 75. Finally, the user places the impeller below the impeller fixing component 8 and tightens the impeller threads... The impeller is arranged with its opening facing downwards and its inner wall facing upwards, so that the opening of the impeller fits onto the impeller fixing component 8 and the inner wall of the opening abuts against the mounting shell 81. At this time, the four clamping rods 86 are fully inserted into the opening of the impeller. Then, the second motor 87 is started, which drives the lead screw 88 to rotate. The lead screw 88 drives the threaded block 89 to move. The threaded block 89 drives the side rod 811 to slide in the sliding hole 810, thereby driving the sleeve 82 to slide on the outer wall of the mounting shell 81. The first mounting seat 83 on the sleeve 82 drives the connecting piece 84 to make the clamping rod 86 rotate around the second mounting seat 85, so that the clamping rod 86 is locked at the opening of the impeller, thereby fixing the impeller below the rotating plate 6.

[0039] The user then moves the mounting plate 1 to the rear pump cover 13 using the movable wheel 14, activates the first hydraulic cylinder 45 to move the first output shaft 46, which in turn moves the rack 47. The rack 47 meshes with the gear 44, causing the gear 44 to rotate, which in turn rotates the connecting shaft 43. The connecting shaft 43 then rotates the rotating block 5 and the rotating plate 6 by 90 degrees, bringing the rotating plate 6 into contact with the limiting member 16. Once the rotating plate 6 is perpendicular to the ground, the user stabilizes the front pump cover and other structures, and then unscrews the baffle 74. The user pushes the mounting plate 1 to align the mounting rod 72 with the impeller shaft 12, and moves the first connecting plate 3 via the electric slide rail 2 to bring the mounting rod 72 closer to the impeller shaft 12. Near the impeller shaft 12, the user first installs the mechanical seal and rear guard plate inside the rear pump cover 13, then starts the first motor 17, causing the first motor 17 to drive the drive component 4 to rotate 180 degrees, thereby aligning the impeller with the rear pump cover 13. Then, the impeller is moved into the rear pump cover 13 by starting the electric slide rail 2. Then, the second motor 87 is controlled to reverse, driving the clamping rod 86 to rotate, so that the impeller can be removed from the impeller fixing component 8 for installation. After the impeller is installed, the first motor 17 is started again to drive the drive component 4 to rotate 180 degrees, so that the mounting rod 72 is aligned with the impeller shaft 12. Then, the remaining guard and front pump cover are installed on the rear pump cover 13.
