Description

Impurity crushing device for sewage lifting pump Technical Field The utility model relates to the technical field of sewage treatment equipment, in particular to an impurity crushing device for a sewage lifting pump. Background The sewage lifting device is a septic tank for effectively lifting and discharging sewage far away from the municipal sewage pipe network or lower than the municipal sewage pipe network to the municipal sewage pipe network or outdoors through the device. The current impurity crushing device for the sewage lifting pump has three designs that 1, a blade or a hammer crusher is adopted to physically crush solid impurities in sewage, and the device is usually arranged at a water inlet of the sewage lifting pump, so that the size of the impurities can be effectively reduced, and the pump body is prevented from being blocked. 2. And the hydraulic crushing device is used for impacting and crushing impurities in the sewage by utilizing high-pressure water flow generated by the hydraulic system. The method can achieve better crushing effect under the condition of not increasing mechanical abrasion. 3. And the electric crushing device is used for crushing impurities in the sewage through a rotary cutter driven by a motor. The device has higher working efficiency and stronger adaptability and can treat different types of sewage. 4.
