Description

Technical Field

[0001] This utility model relates to the technical field of sewage pumps, and in particular to a sewage pump with impeller anti-jamming. Background Technology

[0002] With social progress, rising living standards, and heightened environmental awareness, sewage pumps have become increasingly familiar and widely used. For example, the horizontal sewage pump proposed in existing technology publication CN216241355U includes a pump body, inlet, outlet, first support, impeller, and power source. The power source's shaft extends into the pump body cavity, and the impeller is mounted on the shaft. The power source can be a standard motor or a submersible motor. However, during operation, sewage pumps often experience impeller entanglement or jamming due to the presence of solid matter within the sewage, which can damage the motor and prevent sewage discharge, severely impacting urban life and environmental protection. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a sewage pump with an impeller anti-jamming design that can prevent debris from escaping outward, causing it to come into contact with the impeller, become entangled in the impeller, increase rotational resistance, and thus damage the motor and prevent sewage from being discharged outward.

[0004] This utility model discloses a sewage pump with impeller anti-jamming, comprising a motor, pump casing, outlet pipe, main shaft, impeller, chopping component, filter component, and cleaning component. The bottom of the motor is connected to the top of the pump casing, and the outlet pipe is installed on the pump casing. The main shaft is installed at the output end of the motor and rotates inside the pump casing. The impeller is located inside the pump casing and coaxially mounted on the outer wall of the main shaft. The chopping component is installed at the bottom of the pump casing, the filter component is installed below the chopping component, and the cleaning component is installed inside the filter component. When pumping sewage, the motor is started, which drives the impeller to rotate through the main shaft, and the sewage is discharged through the outlet pipe. The filter component filters and blocks large impurities, and the chopping component can chop up impurities in the sewage, preventing debris from escaping and contacting the impeller, increasing rotational resistance, and thus damaging the motor and preventing sewage from being discharged. The cleaning component can clean the filter component, preventing solid matter from clogging the filter screen and preventing sewage from flowing out.

[0005] Preferably, the chopping component includes a crushing shell, multiple horizontal shafts, multiple sets of crushing teeth, and multiple sets of chopping blades. The top of the crushing shell is connected to the bottom of the pump casing. The main shaft extends into the crushing shell. The multiple horizontal shafts are located inside the crushing shell and are axially mounted on the outer wall of the main shaft. Crushing teeth are installed at the bottom of the horizontal shafts. The multiple sets of chopping blades are located above the horizontal shafts and are axially mounted on the outer wall of the main shaft. Wastewater is input below the crushing shell and then input into the pump casing above the crushing shell. When the main shaft rotates, it drives the multiple sets of crushing teeth to rotate through the horizontal shafts, crushing impurities. At the same time, the main shaft drives the chopping blades to rotate, further crushing the impurities. This prevents impurities from escaping outward, which could cause them to come into contact with the impeller, become entangled in the impeller, increase rotational resistance, and thus damage the motor, preventing the wastewater from being discharged.

[0006] Preferably, the filtration component includes an inlet shell and a filter screen. The inlet shell is located below the crushing shell, and the top of the inlet shell is cone-shaped with the top output end connected to the bottom input end of the crushing shell. An inlet pipe is provided below the inlet shell, and the filter screen is installed inside the inlet shell. Wastewater enters the inlet shell through the inlet pipe, and the filter screen blocks the debris in the wastewater, preventing it from entering the pump body and causing pump blockage.

[0007] Preferably, the cleaning component includes a mounting base and multiple cleaning plates. The main shaft passes through the interior of the water inlet shell and rotates through the middle of the filter screen. The mounting base is installed at the bottom of the main shaft, and multiple cleaning plates are installed on the outer wall of the mounting base. The cleaning plates contact the bottom of the filter screen. When the main shaft rotates, it drives the multiple cleaning plates to rotate through the mounting base, thereby cleaning the filter screen and preventing solid matter from clogging the filter screen and preventing sewage from flowing.

[0008] Preferably, it also includes a water inlet connector, which is installed on the top of the water inlet shell and has a valve. The output end of the water inlet connector is connected to the inside of the water inlet shell. After long-term use, the water inlet connector is connected to the water pipe and the valve is opened to input clean water into the water inlet shell, which can backwash and clean the filter screen, ensure the filtration effect, facilitate maintenance, and improve the service life of the equipment.

[0009] Preferably, it also includes two connecting seats, a handle, and a rubber sleeve. The two connecting seats are symmetrically installed on the left and right sides of the pump housing, the bottom of the handle is rotatably mounted on the connecting seats, and the upper part of the handle is fitted with a rubber sleeve. The handle and connecting seats make it easy to carry and move the equipment by hand, and the rubber sleeve increases the comfort when holding it.

[0010] Preferably, it also includes multiple connecting frames, with the top of the multiple connecting frames axially installed at the bottom of the pump casing, and the bottom of the connecting frames connected to the outer walls of the crushing shell and the water inlet shell; the connecting frames can increase the connection strength of the equipment and ensure stability.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When pumping sewage, the starting motor drives the impeller to rotate through the main shaft, and the sewage is discharged through the outlet pipe. The filter component filters and blocks large impurities, and the crushing component can chop up the impurities in the sewage, which can prevent the debris from escaping outward and causing the debris to come into contact with the impeller and become entangled, increasing the rotational resistance and thus damaging the motor and preventing the sewage from being discharged. The cleaning component can clean the filter component and prevent solid matter from clogging the filter screen, which would prevent the sewage from flowing. Attached Figure Description

[0020] When pumping sewage, the motor 1 starts and drives the impeller 5 to rotate via the main shaft 4, discharging the sewage through the outlet pipe 3. The sewage enters the inlet casing 10 through the inlet pipe, where it passes through the filter screen 11 to block debris from entering the pump body and causing blockage. The sewage enters below the crushing casing 6 and above it into the pump casing 2. When the main shaft 4 rotates, it drives multiple sets of crushing teeth 8 to rotate via the horizontal shaft 7, crushing impurities. At the same time, the main shaft 4 drives the chopping blade 9 to rotate, further crushing the impurities. This prevents debris from escaping and contacting the impeller 5, which could cause it to become entangled and increase rotational resistance, thus damaging the motor. If the filter screen is damaged and cannot discharge sewage, the main shaft 4 rotates, which drives multiple cleaning plates 13 to rotate through the mounting base 12 to clean the filter screen 11, preventing solid matter from clogging the filter screen and causing sewage to be unable to flow. After long-term use, the water inlet connector 14 is connected to the water pipe and the valve is opened to input clean water into the water inlet shell 10, which can backwash and clean the filter screen 11, ensuring the filtration effect, facilitating maintenance, and improving the service life of the equipment.

During operation, the handle 17 and connecting seat 16 facilitate hand transport of the equipment, and the rubber sleeve 18 increases the comfort of gripping. When pumping sewage, the starter motor 1 drives the impeller 5 to rotate through the main shaft 4, discharging the sewage through the outlet pipe 3. The sewage enters the inlet shell 10 through the inlet pipe, and the filter screen 11 blocks the debris in the sewage. The sewage enters below the crushing shell 6 and above the crushing shell 6 into the pump shell 2. When the main shaft 4 rotates, it drives multiple sets of crushing teeth 8 to rotate through the horizontal shaft 7, crushing the impurities. At the same time, the main shaft 4 drives the chopping blade 9 to rotate, further crushing the impurities. This prevents debris from escaping and contacting the impeller 5, which would cause the debris to become entangled and increase the rotational resistance, thus damaging the motor. When the main shaft 4 rotates, it drives multiple cleaning plates 13 to rotate through the mounting seat 12, cleaning the filter screen 11 and preventing solid matter from clogging the filter screen and preventing sewage from flowing.
