Description

Technical Field

[0001] The utility model relates to the field of mechanical anti-clogging devices, in particular to an anti-clogging self-priming pump. Background Art

[0002] The self-priming pump is a self-priming centrifugal pump. It has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. There is no need to install a bottom valve in the pipeline. Before working, it is only necessary to ensure that a certain amount of liquid is stored in the pump body. Different liquids can use self-priming pumps of different materials. The working principle of the self-priming pump is that the pump casing is filled with water before the water pump is started or there is water in the pump casing itself. After starting, the impeller rotates at high speed to make the water in the impeller groove flow to the volute. At this time, a vacuum is formed at the inlet, so that the water inlet check valve opens, and the air in the suction pipe enters the pump and reaches the outer edge through the impeller groove.

[0003] However, it still has some disadvantages. For example, the self-priming pump currently used does not effectively filter the silt in the water during use, causing the silt in the water to enter the water pump. Long-term accumulation will cause the water pump to be damaged and unable to work. In addition, the water inlet pipe in the self-priming pump currently used does not have a disturbing device. The impact of the high-pressure water flow will shorten the service life of the water inlet pipe, and the silt in the water will accumulate inside the water inlet pipe, affecting the entry of water flow.

[0004] In order to solve the above problems, the present application proposes an anti-clogging self-priming pump. Utility Model Content

[0005] The utility model aims to provide an anti-clogging self-priming pump to solve the problems in the prior art proposed in the above background technology that the water pump cannot filter the sediment and causes blockage, and the water inlet pipe has no flow disturbance device and will damage the water pipe.

[0014] The utility model can firstly slow down the flow velocity of the water flow in the water inlet pipe through the coordinated use of the spoiler cross bar, spoiler plate, primary spoiler purification net, telescopic inner frame and secondary spoiler purification net and other parts, to avoid serious wear of the water inlet pipe due to excessive flow velocity.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In this embodiment, Figure 2-3 As shown, a secondary water inlet pipe 8 is movably sleeved on the outer surface of one end of the water inlet pipe 7, a spoiler cross bar 10 is fixedly sleeved on the inner wall of the water inlet pipe 7, a filter fixed base 9 is movably sleeved on the inner wall of the secondary water inlet pipe 8, a filter fixed base 9 is movably sleeved on the outer wall of the filter fixed base 9, a filter fixed top seat 11 is movably sleeved on the outer wall of the filter fixed base 9, a screw placement hole 16 is opened on the outer wall of the filter fixed base 9, a built-in filter frame 14 is sleeved on the inner wall of the filter fixed base 9, an external filter screen 12 is fixedly connected to the outer wall of the filter fixed top seat 11, a locking screw 13 is movably sleeved on the outer wall of the filter fixed top seat 11, and the locking screw 13 is movably sleeved with the screw placement hole 16, and an embedded filter screen 15 is fixedly connected to the outer wall of the built-in filter frame 14. The external filter screen 12 and the embedded filter screen 15 can effectively filter and purify impurities in the water to prevent long-term accumulation of impurities from affecting the operation of the self-priming water pump 5.

[0023] In this embodiment, Figure 4 As shown, the outer wall of the spoiler cross bar 10 is fixedly sleeved with a rotating shaft 17, and the outer wall of the spoiler cross bar 10 is fixedly sleeved with a cross bar rotating ring 18, the outer wall of the cross bar rotating ring 18 is fixedly connected to the inner wall of the water inlet pipe 7, and the outer wall of the rotating shaft 17 is fixedly connected with a spoiler 19, and the front end outer surface of the spoiler 19 is fixedly connected with a primary spoiler purification net 20, and the front end outer surface of the spoiler 19 is movably sleeved with a telescopic inner frame 21, and the upper end outer surface of the telescopic inner frame 21 is fixedly connected with a secondary spoiler purification net 22. The coordination of the spoiler 19 and the primary spoiler purification net 20 can better interfere with the water flow inside the water inlet pipe 7, slow down the flow velocity of the water flow inside the water inlet pipe 7, improve the service life of the water inlet pipe 7, and avoid the accumulation of sediment inside the water inlet pipe 7, causing the pipe to be blocked.

[0024] Working principle:

[0025] First, the user moves the device body 1 to a suitable position through the moving wheels 3 and fixes it to prevent the device body 1 from deviating from the position due to the vibration of the driving motor 4. After the device body 1 is fixed, the water inlet pipe 7 is connected to the secondary water inlet pipe 8 and placed in the water source. Then, the water outlet pipe 6 is put on the upper water outlet trough of the self-priming water pump 5, and then the main control box 2 is used to control the start-up operation of the driving motor 4. The operation of the driving motor 4 drives the self-priming water pump 5 to work. The self-priming water pump 5 generates power to drive the water source into the self-priming water pump 5 through the water inlet pipe 7, and then flows out through the water outlet pipe 6. When the self-priming water pump 5 passes through the water inlet pipe 7 and the secondary water inlet pipe 8, it will first pass through the external filter screen 12 and the embedded filter screen 15 to filter out impurities and sediment in the water. After the water flows into the inside of the water inlet pipe 7, the water flow drives the rotation of the rotating shaft 17, and the rotation of the rotating shaft 17 can drive the turbulence The rotation of the plate 19 can slow down the flow rate of the water inside the water inlet pipe 7, and avoid the damage of the water inlet pipe 7 caused by excessive impact force of the water flow. At the same time, the flowing water in the water inlet pipe 7 is filtered again by the first-level turbulence purification net 20 and the second-level turbulence purification net 22, and finally enters the self-priming water pump 5 and is discharged to the designated location through the outlet pipe 6. When there is a lot of sediment on the embedded filter screen 15 and the external filter screen 12, the user separates the locking screw 13 from the screw placement hole 16, and then separates the filter fixing top seat 11 from the filter fixing base 9, and then removes the built-in filter frame 14 from the inside, and then cleans the external filter screen 12 and the embedded filter screen 15. After completion, the built-in filter frame 14 is combined with the filter fixing top seat 11 and the filter fixing base 9. When replacing the telescopic inner frame 21, it only needs to be pulled out from the front end of the spoiler 19 to achieve quick replacement.

[0026] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
