Anti-clogging device for sewage pump

Abstract

The invention relates to an anti-blockage device of a sewage pump. The anti-blockage device of the sewage pump comprises a connecting rod with a tensioning wheel, a driven gear, a water inlet pipeline, a rotating mechanism, a belt, a cutting blade, a water outlet pipeline, a driving gear, a driving shaft and a driving motor. The water inlet pipeline is connected with the inlet end of the rotating mechanism through a bearing A. The outlet end of the rotating mechanism is connected with the water outlet pipeline through a bearing B, and the rotating mechanism is of a hollow structure. A hole is formed in one side of the wall of the water outlet pipeline, one end of the driving shaft penetrates through the hole formed in the wall of the water outlet pipeline and extends towards the rotating mechanism in the vertical direction of the water outlet pipeline, and the cutting blade is installed at the end, placed on the water outlet pipeline, of the driving shaft. The cutting blade is arranged on the bottom of the rotating mechanism. The other end of the driving shaft is connected with an output shaft of the driving motor. The driving gear is installed on the driving shaft and placed between the driving motor and the hole of the water outlet pipeline. According to the anti-blockage device, the rotating mechanism rotates relative to the water inlet pipeline and the water outlet pipeline by means of centrifugal force, and the cutting blade is used for smashing impurities.

Description

technical field [0001] The invention relates to a device for reducing impurity in front of a sewage pump to reduce clogging, in particular to a sewage pump anti-clogging device. Background technique [0002] Sewage pumps are used in the fields of urban sewage transportation and treatment to enable sewage to obtain mechanical energy to overcome viscous resistance during transmission. [0003] Ordinary sewage pumps do not have a refinement device for impurities in sewage. Sewage with fibers that are easily entangled or bunched and larger granular impurities are likely to be caused by flocs entangled with blades or larger granular impurities at the blades. Blockage, and it is easy to cause the pump to fail to work normally or even the motor to burn out, resulting in the failure of normal sewage discharge; ordinary sewage pumps cannot guarantee long-term safe and stable operation. Therefore, the impurity refinement device has a very good application prospect in the field of sewa...

[0003] Ordinary sewage pumps do not have a refinement device for impurities in sewage. Sewage with fibers that are easily entangled or bunched and larger granular impurities are likely to be caused by flocs entangled with blades or larger granular impurities at the blades. It is easy to cause the pump to fail to work normally or even the motor to burn out, resulting in the failure of normal sewage discharge; ordinary sewage pumps cannot guarantee long-term safe and stable operation. Therefore, the impurity refinement device has a very good application prospect in the field of sewage pumps

[0004] At present, the most used sewage pumps are only equipped with filter screens or pre-cutting blades on the pump shaft to reduce the occurrence of impurity clogging. The existing technology does not have the effect of filtering or cutting refinement when the flow rate of the pump is high. It is not obvious that the installation of the filter needs to be replaced regularly, and the installation of the front cutting blade on the pump shaft will easily lead to poor cutting effect when the flow rate is high, and the flocs will be entangled near the end of the pump shaft, which cannot guarantee high efficiency and high efficiency. Safely reduces the size of impurities in sewage to reduce the likelihood of pump clogging
