Detailed Description
The apartment kitchen waste disposal system using siphon discharge as shown in fig. 1 or 2 includes a plurality of kitchen waste pulverizers 100 connected to a kitchen sink 200a (or a feeding port 200b), the kitchen waste is poured into the kitchen waste pulverizer 100 through a feeding port 101 and then ground by adding water (water may be added through a water adding port or by adding water in other ways), the disposed kitchen waste contains appropriate water to facilitate the transportation of the ground kitchen waste, and a discharging port 102 of the kitchen waste pulverizer 100 is connected to a port 311 of a horizontal pipe 310 (independent of a toilet drain pipe) of a gravity pipe 300.
The horizontal pipe member 310 communicates with the vertical pipe member 320 and is slightly inclined (typically requiring 1-2% inclination) toward the vertical pipe member 320, and the upper end 321 of the vertical pipe member 320 extends out of the roof (collected in a concentrated manner as extending out of the ground) to communicate with the atmosphere.
A set of upper and lower level sensors 410 and 420 are arranged at the lower end 322 of the vertical pipe 320, and the upper and lower level sensors 410 and 420 are not affected by the water flow from the grinder. The lower level sensor 420 is higher than the height of the bottommost horizontal tube 310 interfacing with the vertical tube 320. The tail end 323 of the vertical pipe 320 is communicated with a siphon branch pipe 410 with a quick-opening valve 401 and a siphon main pipe 420 through a transverse pipe 324; specifically, the siphon branch pipe 410 is connected to the siphon main pipe 420 through an elbow 411 of 45 °.
A negative pressure collecting tank 500 is connected to a discharge port of the siphon main pipe 420. The negative pressure collecting tank 500 is internally provided with a stirring device 510, a second liquid level sensor 520 and a vacuum degree measuring device 530; the negative pressure collection tank 500 is connected to a vacuum pump 540 through a vacuum pipe 541. Is connected to the dehydration apparatus 700 through a sewage pipe 600 provided with a sewage pump 610. The solid garbage dehydrated by the dehydration device 700 enters the garbage can 710, and the liquid garbage enters the water tank 720 through the water outlet for further utilization.
The quick-opening valve 401 is a normally closed type, solid-containing liquid from the kitchen waste pulverizer 100 is gathered in a pipeline at the front end of the quick-opening valve 401, the liquid level sensor triggers the quick-opening valve 401 to open when the liquid reaches the maximum liquid level line, the liquid is sucked into the siphon pipeline 400 and flows into the negative pressure collecting tank 500 under the action of pressure difference, and the quick-opening valve 401 is closed again when the liquid level drops to the low liquid level line.
Solid-containing liquid finally enters the negative pressure storage tank 500 under the action of pressure difference, when the liquid in the tank reaches a set height, the sewage pump is started, and the stirring device is started in advance when the sewage pump is started, so that the material is uniform. When the liquid level in the tank is lower than a set value, the sewage pump stops, and the stirring device stops working.
And starting the vacuum pump until the vacuum degree in the pipe reaches a set value along with air leakage or reduction of the vacuum degree in the liquid discharge pipe.
The outlet of the sewage pump is connected with the feed inlet of the centrifugal dehydrator, and the dehydrated solid enters the garbage can 710 through the slag outlet. The liquid enters the tank 720 through the drain opening, both of which can be further utilized.
Due to the adoption of the technical scheme, the kitchen waste generated in the life of residents of a plurality of buildings in a residential district is crushed and transmitted to a place (the feeding port 200b) through a set of gravity pipeline and siphon pipeline, and centralized dehydration is carried out. So as to fully utilize the limited space in the residential district and isolate the odor, bacteria and the like in the kitchen waste treatment process. Increasing the residential community hygiene level. The equipment investment and the waste amount are reduced, and the transportation cost and the kitchen waste disposal cost are greatly reduced. The method solves the environmental protection problems of recycling nutrient substances contained in the kitchen waste and utilizing fertilizers in the waste.
With the important point of fig. 2, some residential areas are old residential areas, where no kitchen waste pulverizer is installed, or no drain pipe dedicated for collecting kitchen waste is designed, or some residential areas are unwilling to install a kitchen waste water heater at home, or are limited by cost, and it is not suitable to install a kitchen waste pulverizer 100 per household, but a certain number of kitchen waste pulverizers 100 are installed in each unit bottom floor or some public areas of the residential areas according to the number of service persons and site conditions, and then the solid-containing liquid is connected into a siphon pipeline system.
With reference to fig. 3, in order to prevent frequent activation of the quick-opening valve 401, a water tank 800 (a ceiling of a floor where equipment such as a negative pressure storage tank 500 is located) is added to the lower end 322 of the vertical pipe 320, an inlet 801 of the water tank 800 is connected to the vertical pipe 320, and an outlet 802 is connected to the siphon branch 410 through the quick-opening valve 401. The water tank 800 is provided with a third liquid level sensor 810, and the third liquid level sensor 810 is provided with a high liquid level 811 and a low liquid level 812, wherein the low liquid level 812 is higher than the height of the water tank outlet 802.
