Problems solved by technology

Sewage contains a certain proportion of sundries. If the water pump is directly transported, the water pump will often be blocked by the impeller of the water pump or burnt due to fibers such as sanitary napkins or other sundries in the liquid medium.
Generally, water tanks or pits are used to collect sewage and pumps are used to directly lift the discharge method, which has the following disadvantages: regular cleaning of sundries in the water tank is required, and the operation and maintenance costs are high; water pumps and pipelines are prone to blockage or damage, which affects the normal discharge of sewage

Embodiment 1

[0021] The present invention comprises a water tank 7, a water inlet pipe 2 containing debris, a water outlet pipe 1 containing debris provided with a check valve 8, an outlet pipe 5 containing no debris, and a water pump 15, which are respectively connected with the water inlet pipe 2 containing debris and the water pump 15 containing debris. Outlet pipe 1, a three-chamber slag storage device 3 connected to the water outlet pipe 5 without debris, the three-chamber slag storage device 3 includes a suspended solid isolation chamber 10, a sediment isolation chamber 14, and an isolation buffer chamber 12 connected in sequence. The suspended matter isolation chamber 10 connected to the object water inlet pipe 2 is provided with a floating ball 9 that can be connected or closed, and a filter screen 11 is provided above the isolation buffer chamber 12 connected to the water outlet pipe 5 without debris.

[0022] Ball float 9 can adopt hollow rubber ball, plastic ball or hollow metal ...

Embodiment 2

[0028] The structure is basically the same as that of Embodiment 1, the only difference is that a dry-installed water pump is used, and the water pump 15 is arranged outside the water tank 7 without debris. Connected; The present embodiment no longer installs the cooling water pipe 4 of the automatic coupler 6 and the cooling motor 13.

[0029] When in use, when the liquid medium containing impurities enters the three-cavity slag storage device 3 through the water inlet pipe 2 containing the impurities and the floating ball 9, the three-cavity slag storage device 3 utilizes the different specific gravity of the liquid medium and the impurities to absorb the liquid that enters the liquid medium. Impurities such as suspended solids (such as sanitary napkins, fibers, etc.), sediments (such as feces and other sundries) are isolated and stored in the corresponding suspended solids isolation chamber 10 and sediment isolation chamber 14, and the isolated medium without impurities Und...

Abstract

The invention relates to a three-chamber sewage lift which is low in operation and maintenance costs, rarely clogs, is free of reflow and has the effect of guaranteeing normal discharge of sewage. The three-chamber sewage lift comprises a water tank, a sundry-containing water incoming pipe, a sundry-containing water outgoing pipe with a check valve, a sundry-free water outgoing pipe, and a water pump. The three-chamber sewage lift is structurally characterized by further comprising a three-chamber residue storage device which is connected with the sundry-containing water incoming pipe, the sundry-containing water outgoing pipe and the sundry-free water outgoing pipe; the three-chamber residue storage device comprises a suspended matter isolating chamber, a sediment isolating chamber, and an isolating buffer chamber which are connected in sequence; a float for opening or closing is disposed in the suspended matter isolating chamber connected with the sundry-containing water incoming pipe, and a filter screen is arranged above the isolating buffer chamber connected with the sundry-free water outgoing pipe.

Description

technical field [0001] The invention relates to sewage lifting equipment, in particular to a three-chamber sewage lifting equipment. Background technique [0002] Nowadays, many buildings or industrial factories and mines need to discharge the liquid medium containing dirt to the outside of the building or into related systems, such as the discharge of domestic sewage in basements, toilets or kitchens, or the sewage discharge of industrial and mining enterprises. Sewage contains a certain proportion of sundries. If the water pump is directly transported, the water pump will often be blocked by the impeller of the water pump or burnt due to fibers such as sanitary napkins or other sundries in the liquid medium. Generally, water tanks or pits are used to collect sewage and pumps are used to directly lift and discharge the method, which has the following disadvantages: the sundries in the water tank need to be cleaned regularly, and the operation and maintenance costs are high;...
