Sewage lifting device easy and convenient to maintain

Abstract

The invention discloses a sewage lifting device easy and convenient to maintain. The sewage lifting device comprises a water tank. A water inlet pipe of the water tank is arranged on a side wall of the water tank, a main function pipeline is arranged between the water inlet pipe of the water tank and a sewage inlet pipe and comprises a metal isolator and a stirring machine, the metal isolator is communicated with the sewage inlet pipe, the stirring machine is communicated with the water inlet pipe of the water tank, and a water outlet of the metal isolator is communicated with a water inlet ofthe stirring machine via a connecting pipe. The sewage lifting device has the advantages that sewage which is fed into the water tank can be treated by the main function pipeline, the metal isolatorand the stirring machine are serially connected with each other to form the main function pipeline, deposition preventive pipelines for the metal isolator can prevent dirt in the metal isolator from being deposited, flowing of water flow in the water tank can be intensified by an internal circulation pipeline of the water tank, the blocked and stopped stirring machine can be restarted by stirringmachine control pipelines, and accordingly the problems of frequent blocking of check valves of the latest sewage lifting devices due to solid and liquid separation, high operation and maintenance costs and severe trouble can be solved by the aid of the sewage lifting device.

Description

technical field [0001] The invention belongs to a sewage lifting device, in particular to a sewage lifting device with easy maintenance. Background technique [0002] The traditional sewage drainage method of building sumps has the disadvantages of polluting the natural environment, having peculiar smell, breeding mosquitoes, requiring personnel to clean up, and high operation and maintenance costs of water pumps. The sewage lifting device was originally used in the drainage of villas, but it has been widely used in the sewage cleaning and drainage of various buildings due to its characteristics of no peculiar smell and no pollution. [0003] At present, the latest sewage lifting device adopts the solid-liquid separation method for drainage. A debris filter is installed on the water inlet branch of the sewage pipe to trap the debris in the filter to prevent the debris from entering the water tank and filter it during the backwashing process. The sundries in the device are d...

Problems solved by technology

[0003] At present, the latest sewage lifting device adopts the solid-liquid separation method for drainage. A debris filter is installed on the water inlet branch of the sewage pipe to trap the debris in the filter to prevent the debris from entering the water tank and filter it during the backwashing process. The sundries in the device are drained away with the sewage, so that the sewage containing sundries will flow through the check valve at the outlet of the water pump. Often, the sundries block the check valve and cause the drainage function to fail. Once it is blocked, it needs to be dismantled. The check valve is manually cleaned, and the operation and maintenance costs are high and very troublesome
