Description

Technical Field

[0001] The utility model relates to the technical field of jet pumps, in particular to a jet pump with an anti-blocking function. Background Art

[0002] A jet pump is a type of fluid-powered pump. It has no mechanical transmission or working components. Instead, it uses the energy of another working fluid as a power source to transport low-energy liquids. It offers excellent safety when used to pump flammable and explosive materials.

[0003] After searching the Chinese patent with publication number CN214404139U, a jet pump with anti-blocking function is disclosed. The sand and gravel in the water can be filtered through the filter plate in the filter box, thereby preventing the sand and gravel from blocking the water outlet. The push-pull rod can be moved downward by the half gear meshing with the rack at the motor drive end. The brush head at one end of the push-pull rod can push the sand and gravel attached to the filter plate to the bottom of the filter box. By regularly cleaning the sand and gravel attached to the filter plate, the fluidity of the water can be improved. The sand and gravel can enter the collection box by their own weight, which is convenient for the collection of sand and gravel. The turbulence from the collection box can be reduced by the water treatment inclined plate. The sand and gravel in the collection box can be discharged by opening the valve. It is easy to use.

[0004] Based on the above search and combined with the existing technology, it was found that the above patent has certain defects. The filter plate is cleaned by motor drive, which is inconvenient to control. The sand and gravel stuck on the filter plate cannot be processed in time, which may cause obstruction of water flow. The additional driving structure takes up a large space and has high installation and maintenance costs. It cannot drive the cleaning structure to rotate according to the flow of internal water, which reduces the efficiency of the jet pump. Utility Model Content

The inner wall of one side of the inlet pipe 7 is fixedly connected to a filter plate 6, and the inner wall of the other side of the inlet pipe 7 is fixedly connected to a ring frame 4. The inner wall of the ring frame 4 is fixedly connected to a cross frame 11, and a bearing 15 is installed on the inner wall of the cross frame 11. A mounting hole is opened on the outer wall of one side of the filter plate 6, and a movable rod 13 is rotatably provided on the inner wall of the mounting hole. A sleeve is fixedly connected to the outer wall of one side of the movable rod 13, and a scraper plate 12 is fixedly connected to the top and bottom outer walls of the sleeve. Brushes 14 are fixedly connected to the outer walls of both sides of the sleeve, and a spiral leaf 5 is fixedly connected to the outer wall of the other side of the movable rod 13. The movable rod 13 is mounted on the inner wall of the bearing 15, and the brush 14 and the scraper plate 12 are slidably connected to the outer wall of the filter plate 6.

[0025] Furthermore, a sand discharge hole is opened on the outer wall of the bottom end of the inlet pipe 7, and a collection box 9 is fixedly connected to the inner wall of the sand discharge hole. A water treatment inclined plate 16 is installed on the top inner wall of the collection box 9. A sand discharge pipe 10 is provided on the outer wall of the bottom end of the collection box 9, and a valve is installed on the inner wall of the sand discharge pipe 10.

[0026] Furthermore, a rectangular hole is provided on one side outer wall of the collecting box 9, and a baffle 18 is slidably connected to the inner wall of the rectangular hole. A fixed plate 17 is fixedly connected to the outer wall of one side of the bottom end of the inlet pipe 7, and a threaded hole is provided on one side outer wall of the bottom of the fixed plate 17. A screw 8 is threadedly connected to the inner wall of the threaded hole. One end of the screw 8 is rotatably connected to one end of the baffle 18, and a turntable is fixedly connected to the outer wall of one side of the screw 8. A semicircular groove is provided on the top outer wall of the collecting box 9. The collecting box 9 is located below the filter plate 6.
