Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a sewage lifting pump. Background Art

[0002] The sewage lift pump is a widely used water treatment equipment. When in use, its suction pipe and pump must be filled with liquid. After the pump is turned on, the impeller rotates at high speed, and the liquid in the sewage lift pump rotates with the blades. Under the effect of centrifugal force, it flies away from the impeller and ejects outward. The ejected liquid gradually slows down in the dispersion chamber of the pump casing, and the pressure gradually increases, and then flows out from the pump outlet and the discharge pipe.

[0003] In the prior art, after searching Chinese patent number CN220487846U, a sewage lifting pump is disclosed; it includes a support seat and a cleaning device. The surface of the support seat is fixedly connected with a pump body and a filter box, and the filter box is provided with a first filter plate and a second filter plate. The cleaning device includes a motor and a rotating member, and the rotating member is connected to the output shaft of the motor through a belt drive. One end of the rotating member is threadedly connected to a moving plate, and the surface of the moving plate is connected with two cleaning members, and the cleaning members are respectively attached to the first filter plate and the second filter plate.

[0004] When treating sewage, a sewage lifting pump is needed to extract it and discharge it into the corresponding treatment water area. Since sewage contains a large amount of impurities, it is easy to cause blockage inside the sewage lifting pump. Existing sewage lifting pumps are generally equipped with a filtering device to filter the sewage, but after long-term use, the inside of the filtering device needs to be cleaned, which is relatively laborious.

[0033] When in use, the filter assembly 2 is flange-connected to the sewage system so that the sewage enters the interior of the filter assembly 2 and is filtered. Then, the pump body 8 is started to extract the filtered sewage from the filter assembly 2.

[0034] The utility model starts the driving component 3 to drive the cleaning component 4 to rotate, and the cleaning component 4 can clean the dirt attached to the bottom end of the filter component 2 to avoid affecting the filtering efficiency of the filter component 2. At the same time, the cleaning component 4 can drive the transmission component 5 fixedly connected to its surface to rotate, and the transmission component 5 drives the cleaning component 6 to rotate. Since the outer surface of the cleaning component 6 is fixedly connected to the interior of the filter component 2 and the interior is connected, the dirt filtered inside the filter component 2 can enter the interior of the cleaning component 6. Then, when the cleaning component 6 rotates, the dirt entering the interior can be transported upward, and then moved out of the interior of the filter component 2, which is convenient for cleaning the dirt inside it and is more labor-saving.

[0036] The interior of the filter box 202 is fixedly connected with a water outlet pipe 206 , and one end of the water outlet pipe 206 is flange-connected to the water pumping end of the pump body 8 .

[0037] By flange-connecting the sewage pipe 203 to the sewage system, the sewage can enter the interior of the filter box 202. With the continuous entry of sewage, it passes through the filter net 204 for filtration, and the filtered dirt is precipitated at the bottom of the filter box 202, so that it cooperates with the inclined plate 205 to move to one side, which is convenient for it to enter the interior of the cleaning component 6. By starting the pump body 8 and cooperating with the outlet pipe 206, the filtered sewage in the filter box 202 can be pumped out, thereby facilitating it to enter the next step.

When the rotating rod 401 rotates, it can drive the cleaning plate 402 fixedly connected to its top end to rotate. Since the top of the cleaning plate 402 fits with the bottom end of the filter 204, when the cleaning plate 402 rotates, it can clean the bottom end of the filter 204, thereby avoiding clogging of the filter 204 and improving the filtering efficiency of the filter 204.

[0043] The rotating rod 401 is driven to rotate by starting the motor 302. When the rotating rod 401 rotates, it can drive the main transmission wheel 501 fixedly connected to its outer surface to rotate. Since the inner side of the main transmission wheel 501 and the inner side of the auxiliary transmission wheel 503 are connected through the transmission belt 502, when the main transmission wheel 501 rotates, it cooperates with the transmission belt 502 to drive the auxiliary transmission wheel 503 to rotate. When the auxiliary transmission wheel 503 rotates, it can drive the cleaning component 6 fixedly connected inside it to rotate, thereby providing stable power for it.

[0044] In one embodiment, for the above-mentioned cleaning component 6, the cleaning component 6 includes a cleaning pipe 601, the outer surface of the cleaning pipe 601 is fixedly connected to the inside of the filter box 202, and the cleaning pipe 601 is rotatably provided with a spiral conveying blade 602, one end of the spiral conveying blade 602 is fixedly connected to a connecting rod 603, and the outer surface of the connecting rod 603 is fixedly connected to the inside of the auxiliary transmission wheel 503;

[0045] A sewage inlet 604 is provided at one side of the sewage cleaning pipe 601 , and a discharge pipe 605 is fixedly connected to the interior of the sewage cleaning pipe 601 .

[0046] When the main transmission wheel 501 cooperates with the transmission belt 502 to drive the secondary transmission wheel 503 to rotate, it can drive the connecting rod 603 fixedly connected inside it to rotate. When the connecting rod 603 rotates, it can drive the spiral conveying blade 602 fixedly connected at one end thereof to rotate, thereby causing it to rotate inside the cleaning pipe 601. Since a sewage inlet 604 is provided on one side of the sewage cleaning pipe 601 and is connected to the interior of the filter box 202, the dirt filtered inside the filter box 202 cooperates with the inclined plate 205 to slide into the interior of the sewage inlet 604, and then cooperates with the continuous rotation of the spiral conveying blade 602 to transport the internal dirt upward, so that it enters the interior of the discharge pipe 605 and is discharged, thereby making it more convenient to clean the internal dirt.

By coordinating the rotation of the cleaning component 4, it is convenient to cooperate with the cleaning component 6 to discharge it, which is more convenient.

[0049] Through the above technical solution, 1. By starting the driving component 3 to drive the cleaning component 4 to rotate, the cleaning component 4 can clean the dirt attached to the bottom end of the filter component 2 to avoid affecting the filtering efficiency of the filter component 2. At the same time, the cleaning component 4 can drive the transmission component 5 fixedly connected to its surface to rotate, and the transmission component 5 drives the cleaning component 6 to rotate. Since the outer surface of the cleaning component 6 is fixedly connected to the interior of the filter component 2 and the interior is connected, the dirt filtered inside the filter component 2 can enter the interior of the cleaning component 6. Then, when the cleaning component 6 rotates, the dirt entering the interior can be transported upward, thereby moving it out of the interior of the filter component 2, which is convenient for cleaning the interior. 1. The dirt can be cleaned with less effort; 2. The rotating rod 401 is driven to rotate by starting the motor 302, and the rotating rod 401 drives the main transmission wheel 501 to rotate, and the main transmission wheel 501 cooperates with the transmission belt 502 to drive the secondary transmission wheel 503 to rotate, and the secondary transmission wheel 503 drives the connecting rod 603 to rotate, and the connecting rod 603 drives the spiral conveying blade 602 to rotate.
