Description

Technical Field

[0001] This invention relates to the field of two-phase flow pump technology, specifically a high-concentration solid-liquid two-phase flow pump. Background Technology

[0002] Two-phase flow pumps are industrial equipment designed for conveying solid-liquid or gas-liquid two-phase flow media. Their core design principle is based on two-phase flow theory, and the efficiency of media conveying is improved by optimizing the impeller structure, flow channel shape, and material process. These pumps use technologies such as electromagnetic coupling drive and three-dimensional twisted blades to overcome the limitations of traditional pumps with large transmission losses. Applicable media include complex fluids such as pulp, slurry, and gas-liquid mixtures with high gas content. According to the differences in media characteristics, they are mainly divided into two categories: solid-liquid two-phase flow pumps and gas-liquid two-phase flow pumps. The working pressure rating covers PN10 to PN64, and the media temperature adaptability range is 0-120℃. Through innovative designs such as reducing transmission components and strengthening the sealing structure, the equipment achieves energy saving, consumption reduction, and extended service life in fields such as papermaking, mining, and municipal engineering.

[0003] During the use of a two-phase flow pump, if the impeller wears or cavitates, the fluid transport efficiency will decrease, the pressure gauge will fluctuate violently, and the outlet flow rate will decrease, requiring the impeller to be replaced. However, if a single blade is worn or cavitated during impeller replacement, the entire impeller needs to be replaced, resulting in waste. To facilitate the replacement of individual blades, a high-concentration solid-liquid two-phase flow pump is provided. Summary of the Invention

By setting up an installation mechanism, the square rod is inserted into the first square groove. At this time, the connecting column is connected into the rotating cylinder. Then, the positioning seat is sleeved on the outer wall of the square rod. After completion, rotating the rotating block drives the first threaded rod to rotate. The rotation of the first threaded rod drives the first bevel gear to rotate. The rotation of the first bevel gear drives the positioning block to move. The positioning block moves and inserts into the positioning groove, fixing the positioning seat on the outer wall of the square rod. The second square groove and the connecting column position the rear plate on the outer wall of the square rod, thereby completing the impeller installation operation and facilitating the impeller installation operation.

The following describes embodiments of the invention based on its overall structure.

[0020] Please see Figures 1 to 11In this embodiment of the invention, a high-concentration solid-liquid two-phase flow pump includes a base 1. A motor 2 and a housing 4 are fixedly connected to the top of the base 1. A connecting shaft 3 is connected to the output end of the motor 2. A side plate 5 is installed at one end of the housing 4. An inlet 6 is fixedly connected to the outer wall of the side plate 5. An outlet 7 is fixedly connected to the top of the housing 4. An impeller is installed in the inner cavity of the housing 4. The impeller is assembled by an assembly mechanism 8 and installed in the inner cavity of the housing 4 by an installation mechanism 9. The assembly mechanism 8 includes a front plate 801, blades 802, and a rear plate 803. Blades 802 are located between the front plate 801 and the rear plate 803. An installation plate 804 is provided at the end of the rear plate 803 away from the blades 802. A limiting groove 805 is formed on the outer wall of the front plate 801, and a first slot 806 is formed on the inner wall of the limiting groove 805. A second slot 807 is formed on the outer wall of the blades 802. A... The third slot 808 has a connecting groove 809 on the outer wall of the mounting plate 804. The assembly mechanism 8 also includes a plug rod 811, which is slidably connected to the inner walls of the first slot 806, the second slot 807, and the third slot 808. One end of the plug rod 811 is fixedly connected to a limit plate 810, and the other end of the plug rod 811 has a horizontal groove 812. The inner wall of the horizontal groove 812 has a fixing groove 813. The mounting plate 804 is rotatably connected to a rotating cylinder 814. One end of the rotating cylinder 814 is fixedly connected to a rotating disk 815. The outer wall of the rotating disk 815 has an inclined groove 816.

The fixing block 819 is inserted into the fixing slot 813 to fix the position of the insert rod 811 and fix the front plate 801, blade 802 and rear plate 803, thereby completing the assembly of the impeller. When replacing blade 802, the impeller is removed from the housing 4, and the rotating cylinder 814 is rotated to move the fixing block 819 out of the fixing groove 813, thus removing the fixing of the insertion rod 811 and taking out the insertion rod 811, thereby separating the front plate 801 from the blade 802. At this time, the front plate 801, the rear plate 803, and the individual blade 802 can be replaced. After completion, the impeller is reassembled, which facilitates the replacement of the front plate 801, the rear plate 803, and the individual blade 802. This allows for the replacement of the part of the impeller that is in direct contact with the fluid, without having to replace the entire impeller, thus avoiding waste.
