After adopting the above scheme, the closed sewage lifter of the utility model is set by said structure design, structure It counts that simple and compact, occupied area is small, is the one third of existing sewage lifter occupied area, by sewage and object through sundries point It completes to be separated by solid-liquid separation from device, and by the way that dirt filter is arranged on sundries separator and sewage pump, hair etc. can be prevented miscellaneous Object winds sewage pump, to guarantee the normal work of sewage pump, when draining, is taken away by the power sewage recoil of sewage pump discharge miscellaneous Sundries in object separator, sundries do not enter water storage tank, realize without precipitating, do not contact sewage pump leaf when exempting to draw clearly, and draining Wheel, will not block sewage pump;By dual pump design, worked alternatively by PLC control double pump, the using and the reserved avoid caused by corrosion Blocking, the sewage deposit after being separated by solid-liquid separation is less in a device, and the residence time is shorter, with into row, no secondary fermentation Foul smell generate, total closed type cabinet blocks peculiar smell in case to drift, and stable and reliable operation, best in quality, maintenance rate is low, adopts It is made of stainless steel material, long service life, by being equipped with liquid level sensor and alarm device on water storage tank, one facilitate oneself Dynamicization control, two can notify user's sewage that situation is discharged, by installing at least one spray structure on sundries separator, It can guarantee that the tiny precipitating of water tank bottom is discharged together with sewage.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the closed sewage lifter of the utility model.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art The utility model can be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
The structural schematic diagram of the closed sewage lifter of the utility model as shown in Figure 1, including it is stainless by SUS 304 Water storage tank 1 made of Steel material, the water storage tank 1 are cuboid.The upper surface of water storage tank 1 is equipped with liquid level sensor 2.
The upper end of water storage tank 1 is connected to by water inlet pipe 3 with one end of four-way connection 4, four-way connection 4 be by SUS 304 not Rust Steel material is made.The second end of the four-way connection 4 is water inlet 5.Other two connector of three-way connection 4 respectively with connecting tube 6 connections, connecting tube 6 are made of 304 stainless steel material of SUS.It is separately installed in two connecting tubes 6 into water check-valves 7, two The other end of connecting tube 6 is connected to drainpipe 8 respectively, and drainpipe 8 is made of 304 stainless steel material of SUS.Two drainings Outlet check valve 9 is separately installed on pipe 8.Two drainpipes 8 are connect with sundries separator 10 respectively, two drainpipes 8 The other end is connected together.The spray knot for rinsing water storage box cavity is separately installed on the staving of two sundries separators 10 Structure, spray structure can be gondola water faucet structure or spray tube, and the present embodiment uses gondola water faucet structure 11, is provided on gondola water faucet structure 11 more A spray apertures.The outlet end of two sundries separators 10 is connect with the input end of sewage pump 12 respectively, two sundries separators 10 Outlet end and the input end of sewage pump 12 be separately installed with dirt filter (not shown).Sewage pump 12 uses water pump leaf Wheel, sewage pump 12 is controlled by PLC control system to be started.Two sundries separators 10 and two sewage pumps 12 are all set in water storage tank In 1.
When work, when the sewage containing sundries enters the equipment through water inlet 5, distinguished by two water inlet check-valves 7 Into two sundries separators 10, sundries, which is separated, to be temporarily stored in sundries separator 10, and the sewage of no-sundries is through dirt mistake Filter enters in water storage tank 1, prevents the impurity such as some hairs from entering sewage pump 12 and enwinding sewage pump in this way, and it is normal to influence it Work.
When the sewage in water storage tank 1 reaches setting height, liquid level sensor 2 and alarm device work and PLC are notified to control By PLC control system starting sewage pump 12 water storage tank 1 is discharged by force in sewage by system.Water flow can will be located at the sundries point of left part It is discharged from the outlet check valve 9 that the sundries kept in device 10 passes through the left part together from drainpipe 8, under the action of water pressure, left part Water inlet check-valves 7 close, sewage will not flow back into toilet, be now placed in water inlet check-valves 7, the sundries separator 10 of right part Continue to accept new water, will not influence and used with drainage facility.When sewage is down to low liquid level in water storage tank 1, left part sewage pump 12 stop working, and the opening of water inlet check-valves 7 of the left part readmits water, and the outlet check valve 9 of left part, which is closed, prevents draining 8 sewage backflow of pipe.When sewage reaches setting height again in water storage tank 1, PLC control system control right part sewage pump 12 is opened Dynamic, the course of work is identical as left part.Two sewage pumps 12, which are realized, to be repeated to work alternatively.
When sewage pump 12 works, water storage is stirred in the inner cavity for the water flow meeting auto-flushing water storage tank 1 that gondola water faucet structure 11 sprays The tiny precipitating of 1 bottom of case is allowed to be discharged together with sewage.
The closed sewage lifter structure design of the utility model is simple and compact, occupied area is small, is that existing sewage mentions Sewage and object are completed to be separated by solid-liquid separation by the one third for rising installation area through sundries separator 10, and by sundries point From dirt filter is arranged on device 10 and sewage pump 12, it can prevent the sundries such as hair from winding sewage pump 12, to guarantee sewage The normal work of pump 12, when draining, the sundries in sundries separator 10 is taken away in the power sewage recoil being discharged by sewage pump 12, miscellaneous Object does not enter water storage tank 1, realizes without precipitating, does not contact 12 impeller of sewage pump when exempting to draw clearly, and draining, will not block sewage pump 12;By dual pump design, worked alternatively by PLC control double pump, the using and the reserved avoid corroding caused blocking, through being separated by solid-liquid separation Sewage deposit afterwards is less in a device, and the residence time is shorter, with it is generated into the foul smell with row, no secondary fermentation, entirely Closed cabinet blocks peculiar smell in case to drift, stable and reliable operation, best in quality, and maintenance rate is low, using stainless steel material system At, long service life, by being equipped with liquid level sensor 2 and alarm device on water storage tank 1, one facilitates automation control, and two To notify user's sewage that situation is discharged, by installing at least one spray structure on sundries separator, it is ensured that storage The tiny precipitating of 1 bottom of water tank is discharged together with sewage.
Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
