Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure pumps, in particular to a high-pressure spray dust suppression water pump which is easy to maintain. Background Art

[0002] The technical principle of the high-pressure spray dust suppression system: A high-pressure water pump is used to boost the pressure to a certain level. Ultrafine atomized particles (10-150μm) are generated through a high-performance nozzle, forming a fog cloud above the dust emission point, completely covering it. This allows dust to completely enter the fog cloud and combine with the atomized particles. The atomized particles then capture the dust, allowing the water mist particles to collide and condense with the dust particles, causing them to settle to the ground due to gravity. This dust suppression at the source effectively addresses the challenge of managing unorganized dust emissions in uncontained environments. The core equipment of the high-pressure spray dust suppression system is the high-pressure spray dust suppression pump.

The pushing mechanism 6 includes an arc block 61, an arc surface 62, a movable block 63 and a fixed block 64. The arc block 61 is fixedly installed on one side surface of the annular plate 71, and the fixed block 64 is fixedly installed on one end surface of the bearing 12. A limiting rod 65 is installed in the fixed block 64 for sliding through. A spring 66 is fixedly installed between the movable block 63 and the fixed block 64. One side surface of the movable block 63 is fixedly connected to one end of the limiting rod 65, and the limiting rod 65 is located inside the spring 66.

[0021] In this embodiment, a curved surface 62 is provided on one side surface of the curved block 61, and the movable block 63 overlaps the curved surface 62 under the action of the spring 66; a first fixing column 72 and a second fixing column 73 are fixedly installed at two places on the outer surface of one side wall of the fixed tube 2, and a limiting screw 75 is threadedly installed on the outer surface of the fixed tube 2 near the first fixing column 72; a sleeve 76 is fixedly installed on one side surface of the annular plate 71.

[0022] Specifically, when maintenance is needed, adjust and remove the limit screw 75 so that the annular plate 71 can rotate, insert the external tool into the sleeve 76, drive the annular plate 71 to rotate, so that the arc block 61 rotates, and the movable block 63 slides to the high position of the arc surface 62. Under the push of the spring 66, the limit rod 65 shortens to release the restriction on the pump cover 4, which is convenient for maintenance and cleaning of the spiral blade 10. During installation, install the sealing ring 11 and the pump cover 4 inside the fixed tube 2, rotate the annular plate 71 in the opposite direction to make the arc block 61 deviate, drive the movable block 63 to move toward the center of the fixed tube 2, so that the limit rod 65 is inserted and limits the pump cover 4 from falling out, and then use the tool to install the limit screw 75, limiting the limit column 74 between the first fixed column 72 and the limit screw 75, so as to fix the position of the annular plate 71, and the installation is convenient and fast.
