Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description.
As shown in figure 1, the utility model relates to a kitchen garbage deoiling device, the pre-treatment process section of mainly used kitchen garbage, the device divide into five regions, are respectively for blocking sediment district, oil removal district, aeration district, air supporting district and ejection of compact district. Wherein the slag blocking area comprises a feed inlet 1, a slag blocking basket 2 and a No. 1 sewage outlet 3; the oil separating area comprises a chain oil scraper 4, an oil collecting tank 8, an oil outlet 9 and a 2# sewage outlet 10; the aeration zone comprises a dosing port 11 and an aeration device 12; the air flotation zone comprises a reflux system 16, a chain slag scraper 17, a slag collecting groove 18 and a slag discharge port 19; the discharge area comprises a liquid level sensor 20 and a discharge port 21.
Incoming material kitchen garbage gets into among the deoiling device through feed inlet 1, and great impurity can be blocked sediment basket 2 interception in the kitchen garbage, and the sediment district bottom deposit is blocked in the evacuation to 1# drain, and the sediment district bottom deposit is separated to the evacuation to 2# drain. And then, the kitchen waste enters an oil separation area, the purpose of separation is achieved by utilizing the difference of specific gravity of grease and water in the kitchen waste, the kitchen waste is pushed into an oil collecting tank 8 by a chain oil scraper 4 and then is discharged through an oil discharge port 9, and the grease can be recycled after being processed. The impurities precipitated in the slag blocking area and the oil separation area are accumulated to the bottom and are discharged through the No. 1 sewage outlet 3 and the No. 2 sewage outlet 10. However, the oil separation area cannot completely recover the grease in the kitchen waste, and the residual grease can affect the treatment efficiency if the residual grease directly enters the subsequent kitchen waste treatment equipment without being treated. Therefore, an aeration zone and an air flotation zone are arranged to carry out advanced treatment on the effluent of the oil separation zone. After the water discharged from the oil separation zone enters the aeration zone, PAC (polyaluminium chloride) can be added through the chemical adding port 11 to carry out demulsification, the aeration shaft 14 is driven by the aeration motor 13, the impeller 15 rotates at a high speed to form negative pressure under the liquid level, countless micro-bubbles are generated to bring residual grease and suspended matters in the kitchen waste to the surface of the kitchen waste, and the reflux system 16 is arranged to reflux the kitchen waste in the air floatation zone to the aeration zone, so that the treatment efficiency of the kitchen waste is improved. The chain residue scraper 17 scrapes the grease and suspended matters on the liquid surface into a residue collection groove 18 and discharges the grease and suspended matters through a residue discharge port 19. The liquid level sensor 20 in the discharging area can feed back the liquid level in the oil removing device, so that the kitchen waste feeding and discharging amount can be controlled conveniently, and the kitchen waste is finally discharged through the discharging hole 21.
The above is only the preferred embodiment of the present invention, but it is not limited to any form, and the related technical field personnel can modify or change the above embodiments by any equivalent, all falling within the protection scope of the present invention.
