The height of the top of the siphon pipe from the liquid level of the water inlet container cannot exceed the water column height which can be maintained by the atmospheric pressure. The liquid level pressure of the water inlet is higher than that of the water outlet.
The waste water containing the kitchen waste, which is ground by each waste grinding device treated nearby, is conveyed to a centralized treatment room for centralized dehydration and oil separation treatment, so that the kitchen space is fully utilized, meanwhile, the taste, bacteria and the like of the kitchen waste are isolated, the sanitation grade of a kitchen is increased, and the equipment investment and the operation cost are reduced. The invention can be combined in a modularization way, can efficiently treat kitchen waste nearby and can be far away from a kitchen operation area. The vacuum pump does not operate basically, and waste water is conveyed by the atmospheric pressure difference, so that the energy consumption is low, the noise is low, and the pipeline installation does not need gradient.
As shown in fig. 1 or 2, the system for centralized treatment of kitchen waste in a commercial kitchen by siphon discharge comprises a plurality of kitchen waste collection stations 100 distributed at different kitchen waste collection points in the commercial kitchen, and the kitchen waste is collected in the kitchen waste collection stations 100.
With particular reference to fig. 2, each kitchen waste collecting station 100 comprises a kitchen waste grinder 110 and a water tank 120, the kitchen waste grinder 110 has a waste water outlet 111 containing kitchen waste, the ground waste water containing kitchen waste is discharged into the water tank 120 through a feed inlet 121 of the water tank 120, and a 90-degree bend does not exist in a pipeline between the waste water outlet 111 and the feed inlet 121.
Be provided with the level measurement device 122 of measuring high low liquid level in the water tank 120, the delivery port 124 of water tank 120 is less than the position of low liquid level to through install the first pipeline 300 of quick-open valve 310 with the feed inlet 201 of kitchen garbage negative pressure storage jar 200 links to each other, and kitchen garbage collection station 100 can set up in the different places and the different floors in commercial kitchen. But the lowest floor is not higher than the floor where the kitchen waste negative pressure storage tank 200 is located, so that the siphon effect can be ensured.
The first pipe 300 comprises a PVC pipe and pipe members connected together, the first pipe 300 has a pressure of 10kg and is laid along the wall or ceiling of a commercial kitchen, fixed by brackets or hangers every 1.6m, and an inspection hole is provided every 6mPVC pipe.
