Description

Technical Field

[0001] The utility model relates to the technical field of sewage pumps, in particular to an anti-clogging sewage pump. Background Art

[0002] A sewage pump is a device used to discharge wastewater, sewage or other liquids. It is mainly used to transport wastewater or sewage from a low place to a high place for further treatment or discharge. Sewage pumps are often used in industrial wastewater treatment.

[0003] The existing sewage pump uses a motor to rotate the impeller in the sewage pool to discharge the sewage to other locations for further treatment. However, there are many debris in the sewage pool, such as ropes and wires on the packaging of industrial products. When the ropes and the like are twisted into the shaft, the motor is easily damaged. Existing protective measures include a filter and a disc cutter. The filter is set at the water suction port of the sewage pump. Large debris is blocked outside the suction port through the filter to prevent large debris from being stuck inside the sewage pump. However, the filter is set at the water suction port of the sewage pump, and its filter is relatively small, so that the filter is easily wrapped by paper, plastic bags, etc. flowing with the water, so that the water suction port is blocked. Secondly, the disc cutter cuts the debris into pieces during operation and then discharges them. As for hair, although some long hair is cut into short hair, relying solely on the disc cutter, as time goes by, the internal shaft of the sewage pump is easily entangled with hair, causing the sewage pump to be blocked or the motor to be damaged.

[0004] Therefore, the utility model provides an anti-clogging sewage pump to solve the above problems. Utility Model Content

[0012] Beneficial Effects

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] See also Figure 1-5 A blockage-resistant sewage pump comprises a pump body 1, a flange 2 is threadedly connected to the side end of the pump body 1, a filtering mechanism and an intercepting mechanism, the filtering mechanism is arranged on the outside of the pump body 1, and the intercepting mechanism is arranged at the bottom of the pump body 1.

[0027] The filter mechanism comprises a filter housing 31 , which is arranged outside the pump body 1 , a first filter cover component 32 is embedded in the upper side of the filter housing 31 , and a second filter cover component 33 is embedded in the side end of the first filter cover component 32 .

[0028] The pump body 1 is respectively engaged with the first filter cover component 32 and the second filter cover component 33. The first filter cover component 32 and the second filter cover component 33 are provided with first filter holes, and the side wall of the filter housing 31 is provided with second filter holes. The diameters of the first filter holes and the second filter holes are both 5 cm.

[0029] Working process: Place the pump body 1 inside the filter housing 31, manually embed the first filter cover component 32 and the second filter cover component 33 into the filter housing 31, and when the pump body 1 is started, the sewage flows into the filter housing 31 from the first filter hole and the second filter hole, and the large debris is blocked outside the filter housing 31. The pump body 1 is set inside the filter housing 31, so that it is difficult for larger debris to block all the first filter holes and the second filter holes. Secondly, the first filter holes and the second filter holes are set to have a diameter of 5 cm each to prevent the first filter holes and the second filter holes from being blocked by sludge due to their small holes.

[0030] Embodiment 2:

[0031] See also Figure 1-5 This embodiment provides an anti-clogging sewage pump technical solution based on the first embodiment:

[0032] The interception mechanism comprises a rotating ring 41 . An annular groove is arranged at the bottom end of the pump body 1 . The rotating ring 41 is slidably connected in the annular groove. Four threaded rods 42 are fixedly connected to the lower side of the rotating ring 41 .

[0033] The interception mechanism also includes a filter plate 44, a bolt 46 and a gasket 47. A cutting disc 45 is provided at the front end of the filter plate 44, a slot is provided on the filter plate 44, four threaded holes are provided on the lower side of the pump body 1, a fixing ring 43 is provided on the front side of the rotating ring 41, the bolt 46 is threadedly connected to the threaded hole, and the gasket 47 is provided between the threaded hole and the bolt 46.

[0034] The front end of the threaded rod 42 is threadedly connected to the second intercepting rod 491, the lower side of the second intercepting rod 491 is fixedly connected to the guide blade 48, the lower side of the guide blade 48 is fixedly connected to the first intercepting rod 49, and a plurality of rubber soft rods are arranged on the outer sides of the first intercepting rod 49 and the second intercepting rod 491. The materials of the second intercepting rod 491, the guide blade 48 and the first intercepting rod 49 are all plastic.

[0035] Working process: the intercepting mechanism is arranged at the water suction port. As the impeller inside the pump body 1 rotates, water flows toward the water suction port. When the water flows through the guide blade 48, the shape of the guide blade 48 causes the rotating ring 41 to rotate, so that the first intercepting rod 49 and the second intercepting rod 491 rotate around the water suction port. During the rotation of the outer rubber soft rods of the first intercepting rod 49 and the second intercepting rod 491, most of the long hair is entangled in the rubber soft rods. When a small number of long hairs pass through the notches of the filter plate 44, the long hairs are cut short by the cutting disc 45. When more hairs are entangled on the second intercepting rod 491 and the first intercepting rod 49, the whole is too heavy, and the thrust exerted on the guide blade 48 continues to prevent it from rotating. A coil of hair entanglement is formed between the second intercepting rod 491 and the first intercepting rod 49, which still has a blocking effect on the subsequent hair entering. After a period of time, the hairs on the first intercepting rod 49 and the second intercepting rod 491 are manually cleaned.
