Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, the profit solid separation device of kitchen castoff described in the utility model is made up of for three sections vapor mixing section, solid-liquid separation section and oily water separation section.After kitchen castoff was pulverized through pulverizer, the solid-state slag particle that forms the about 10 * 10mm of particle diameter formed the mixture of water ratio about 80%～90%, by carrying to the vapor mixing section after the sludge pump suction slag liquid tempering tank 10 in and liquid mixing.The vapor mixing section is provided with steam heater 2, the steam that the steam-in of steam heater 2 is formed by the manual valve that is arranged in parallel and magnetic valve adds pipeline 1 input high-temperature steam, the suction port of steam heater 2 is communicated to slag liquid tempering tank 10 by sludge pump, the jet orifice of steam heater 2 is communicated with the input terminus at solid-liquid separating machine 5, and is provided with one tunnel opposing steam flow bypass 9 that check valve is installed and feeds slag liquid tempering tanks 10.The leakage fluid dram 4 of solid-liquid separating machine 5 is connected to the input aperture of water-and-oil separator 7, and slag-drip opening 6 belows arrange slag liquid mixing tank 8.The steam heater 2 that the utility model adopts is the commercial goods, and core component is Rafael nozzle, fully mixes the back from the aditus laryngis current that spray into and the steam that sprays into from inclined hole and flows out, and steam and water mix in flow at high speed, noiselessness, friction.The solid-liquid separating machine 5 that the utility model adopts be commercially available horizontal screw unloading whizzer, and its principle of work is to utilize the solid-liquid difference in specific gravity, and relies on centrifuge field to make it to enlarge several thousand times, solid phase under action of centrifugal force by sedimentation, thereby the realization solid-liquid separation.During real work, feed operating pressure 0.7MPa～0.9 MPa in the steam-in of steam heater 2, temperature is the above saturation steams of 150 degree, and steam consumption is about 2T/h, mixes with slag liquid that sludge pump aspirates from slag liquid tempering tank 10 and it is quickly heated up to about 80～90 ℃.Mixed solution is joined in the spiral inner core of solid-liquid separating machine 5 by central feed tube, enters rotary drum by charging opening after accelerating; Liquid in the mixed solution flows to the big end of rotary drum, solid particles sediment in the liquid is to rotatory drum wall, form sediment, pushed to the rotary drum small end by spiral, from being expelled to slag-drip opening 6 in the slag liquid mixing tank 8, liquid then is expelled to water-and-oil separator 7 through helical channel by the leakage fluid dram 4 of the big end of rotary drum after rotary drum conical cylinder section dehydration.Setting according to sequence of control, the solid-liquid separating machine fully loaded working clearance of 5 work, open the check valve of opposing steam flow bypass 9, the mixed solution of high temperature is directly returned in the slag liquid tempering tank 10, has so both guaranteed the continuous firing of steam heater 2, has coordinated the Connection Step of each equipment, and under the situation that utmost point cold air is waited, also can be to carrying out preheating in the slag liquid tempering tank 10, thus guarantee its flowability, prevent grease solidify after too dense thick situation about can't aspirate.
Water-and-oil separator of the present utility model 7 adopts commercially available vertical disc separator, and rotary drum is contained in the vertical shaft upper end, by transmission mechanism by motor drive high speed rotating; One group of video disc that is nested in is mutually together arranged in the rotary drum, leave very little gap between video disc and the video disc; Emulsion adds rotary drum by the feed-pipe that is positioned at the rotary drum center, when the gap flow through between the video disc, drop is deposited to video disc and forms liquid layer under the whizzer effect, be divided into heavy-fluid (water) and light liquid (oil) by the density difference, heavy-fluid (water) flows along the video disc internal surface to rotatory drum wall, is expelled in the slag liquid mixing tank 8 through water outlet; Light liquid is expelled to oil outlet pipe 3 to center flow through oil outlet.
Slag liquid mixing tank 8 mixes the solid slag particle of slag-drip opening 6 outputs of solid-liquid separating machine 5 again with the water outlet of water-and-oil separator 7, and inputs to later process by pipeline.For example the disclosed technology of utilizing flora to ferment dining-kitchen organic waste of prior art can obtain soil improvement agent or liquid fertilizer with slag particle mixed solution fermentative preparation; Not only take full advantage of it and include fertilizer efficiency, and avoided the pollution of discharge of wastewater generation and sewage treatment facility and the running cost of increase.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of the utility model spirit, the utility model can be done any type of modification.
