AI Technical Summary
[0002]目前,针对餐饮废水同层排放中存在的普遍问题如下:餐饮含油废水排入集水池内经过一定的停留时间后完成了首次油水分离,首次分离出来的废弃油脂漂浮在集水池上方和一些漂浮杂物在靠近集水池四周侧壁附近时很快就粘附在集水池侧壁上,集水池内的潜水排污泵无法将集水池内四周侧壁上粘附的油脂抽走,这样随着厨房不断使用中反复排入集水池内的餐饮废水反复的完成首次油水分离,并产生废弃油脂和漂浮杂物不断的在集水池四周侧壁上粘附,就会产生集水池内四周侧壁出现大量的结块、结壳、废弃油脂及漂浮杂物堆积现象,这种结壳、堆积现象不仅会造成集水池内水靠近侧壁固定的位控制元件无法正常完成感应工作,还会产生长期的垃圾堆积发出恶臭等污染环境问题
[0009] Compared with the prior art, this utility model uses high-efficiency oil-floating ducts fixedly distributed around the water collection tank to spray high-pressure gas, forming high-pressure flotation on the surrounding side walls. This pushes the floating oil around the water collection tank towards the center, ensuring that the floating oil separated initially does not accumulate on the surrounding side walls and thus avoids the phenomenon of wall adhesion. In other words, the high-pressure gas forming high-pressure flotation on the surrounding side walls pushes the floating oil towards the center of the water collection tank, thus successfully achieving the effect of preventing the floating oil from adhering and accumulating on the surrounding side walls. Furthermore, it can be combined with the self-adjusting floating oil suction device of the applicant's previous patent application No. 202521639018.6 to automatically absorb and transport the floating oil and its floating debris that have moved and accumulated to the center of the water collection tank, thereby maintaining a relatively clean and hygienic overall environment within the water collection tank.

Abstract
Description
[Technical Field]
[0001] This utility model relates to a high-efficiency aggregation technology for floating oil and scum in the field of oil-water separators, specifically a high-efficiency air flotation oil aggregation device. [Background Technology]
[0002] Currently, the common problems in the same-floor discharge of catering wastewater are as follows: After a certain retention time, the oily wastewater from catering enters the collection tank and completes the initial oil-water separation. The waste grease separated in the first separation floats on the top of the collection tank, and some floating debris quickly adheres to the side walls of the collection tank when it is near the perimeter. The submersible sewage pump in the collection tank cannot remove the grease adhering to the side walls. As the kitchen continues to be used, the catering wastewater discharged into the collection tank repeatedly completes the initial oil-water separation, and waste grease and floating debris continue to adhere to the side walls of the collection tank. This results in a large amount of clumps, crusts, waste grease, and floating debris accumulating on the side walls of the collection tank. This crusting and accumulation not only prevents the level control element fixed near the side wall of the collection tank from working properly, but also causes long-term garbage accumulation and odor pollution, which pollutes the environment. [Utility Model Content]
[0003] The purpose of this invention is to address the aforementioned shortcomings by providing an air-flotation high-efficiency oil collection device that ensures that the floating oil initially separated in the collection tank does not accumulate on the surrounding side walls of the collection tank, thus preventing wall-hanging accumulation.
[0004] To achieve the above objectives, a high-efficiency oil-aggregating flotation device is designed, comprising a high-pressure air flotation device 2, an air flotation distributor 5, and a catering wastewater collection tank 7. The catering wastewater collection tank 7 is connected to an inlet pipe 6. The high-pressure air flotation device 2 is fixed above the catering wastewater collection tank 7. The high-pressure air flotation device 2 provides high-pressure gas. The outlet of the high-pressure air flotation device 2 is connected to the air flotation distributor 5 via a pipe. The air flotation distributor 5 is connected to a high-efficiency oil-aggregating air flotation conduit 9 via an air flotation conduit connecting hose 8. The high-efficiency oil-aggregating air flotation conduits 9 are evenly distributed and fixedly installed on the inner sidewalls surrounding the catering wastewater collection tank 7. The air flotation distributor 5 evenly disperses the high-pressure gas, which enters each high-efficiency oil-aggregating air flotation conduit 9 through the air flotation conduit connecting hose 8, and the high-pressure gas is sprayed out from each high-efficiency oil-aggregating air flotation conduit 9 onto the sidewalls surrounding the catering wastewater collection tank 7.
[0005] Furthermore, the outlet end of the high-pressure air flotation device 2 is connected to the high-pressure air flotation outlet pipe 3, the other end of the high-pressure air flotation outlet pipe 3 is connected to the air flotation distributor connecting hose 4, and the other end of the air flotation distributor connecting hose 4 is connected to the air flotation distributor 5.
[0006] Furthermore, the high-efficiency oil-floating air flotation duct 9 is fixed to the air flotation duct mounting bracket 11 by the air flotation duct fixing ring 10, and the air flotation duct mounting bracket 11 is fixed to the side wall of the catering wastewater collection tank 7 by expansion bolts 12.
[0007] Furthermore, a high-pressure air flotation rain cover 1 is provided at the high-pressure air flotation device 2, and the high-pressure air flotation device 2 is fixed below the high-pressure air flotation rain cover 1.
[0008] Furthermore, the water inlet pipe 6 of the collection tank is located at the upper part of the catering wastewater collection tank 7, and the oily wastewater from the kitchen is discharged into the catering wastewater collection tank 7 through the water inlet pipe 6.
[0009] Compared with the prior art, this utility model uses high-efficiency oil-floating ducts fixedly distributed around the water collection tank to spray high-pressure gas, forming high-pressure flotation on the surrounding side walls. This pushes the floating oil around the water collection tank towards the center, ensuring that the floating oil separated initially does not accumulate on the surrounding side walls and thus avoids the phenomenon of wall adhesion. In other words, the high-pressure gas forming high-pressure flotation on the surrounding side walls pushes the floating oil towards the center of the water collection tank, thus successfully achieving the effect of preventing the floating oil from adhering and accumulating on the surrounding side walls. Furthermore, it can be combined with the self-adjusting floating oil suction device of the applicant's previous patent application No. 202521639018.6 to automatically absorb and transport the floating oil and its floating debris that have moved and accumulated to the center of the water collection tank, thereby maintaining a relatively clean and hygienic overall environment within the water collection tank.

[0014] The present invention will be further described below with reference to the accompanying drawings:
[0015] As attached Figure 1 To be continued Figure 3As shown, this utility model provides an air flotation-type high-efficiency oil-aggregating device, including a high-pressure air flotation device 2, an air flotation distributor 5, and a catering wastewater collection tank 7. The catering wastewater collection tank 7 is connected to a collection tank inlet pipe 6. The high-pressure air flotation device 2 is fixed above the catering wastewater collection tank 7. The high-pressure air flotation device 2 is used to provide high-pressure gas. The gas outlet of the high-pressure air flotation device 2 is connected to the air flotation distributor 5 through a pipe. The air flotation distributor 5 is connected to the high-efficiency oil-aggregating air flotation conduit 9 through an air flotation conduit connecting hose 8. The high-efficiency oil-aggregating air flotation conduit 9 is evenly distributed and fixedly installed on the inner sidewalls around the catering wastewater collection tank 7. The air flotation distributor 5 evenly disperses the high-pressure gas into each high-efficiency oil-aggregating air flotation conduit 9 through the air flotation conduit connecting hose 8, and the high-pressure gas is sprayed out from each high-efficiency oil-aggregating air flotation conduit 9 to the sidewalls around the catering wastewater collection tank 7.
[0016] The high-pressure air flotation device 2 is equipped with a high-pressure air flotation rainproof cover 1, and the high-pressure air flotation device 2 is fixed below the high-pressure air flotation rainproof cover 1. The water inlet pipe 6 of the collection tank is located at the upper part of the catering wastewater collection tank 7, and the oily wastewater from the kitchen is discharged into the catering wastewater collection tank 7 through the water inlet pipe 6. The air outlet end of the high-pressure air flotation device 2 is connected to the high-pressure air flotation air outlet pipe 3, and the other end of the high-pressure air flotation air outlet pipe 3 is connected to the air flotation distributor connecting hose 4. The other end of the air flotation distributor connecting hose 4 is connected to the air flotation distributor 5. The high-efficiency oil-concentrating air flotation duct 9 is fixed to the air flotation duct mounting bracket 11 by the air flotation duct fixing ring 10. The air flotation duct mounting bracket 11 is fixed to the four side walls of the catering wastewater collection tank 7 by expansion bolts 12.
[0017] The working principle of this air flotation high-efficiency oil-concentrating device is as follows: Oily wastewater from the kitchen is discharged into the catering wastewater collection tank 7 through the inlet pipe 6. The inlet pipe 6 is connected to the catering wastewater collection tank 7 and is located at the upper part of the catering wastewater collection tank 7. The high-pressure air flotation device 2, fixed above the catering wastewater collection tank 7, is fixed below the high-pressure air flotation rainproof cover 1. It is connected to the air flotation distributor 5 through the high-pressure air flotation outlet pipe 3 and the air flotation distributor connecting hose 4. The air flotation distributor 5 is connected to the high-efficiency oil-concentrating air flotation conduit 9 through the air flotation conduit connecting hose 8. The high-efficiency oil-concentrating air flotation conduit 9 is placed on the air flotation conduit mounting bracket 11 through the air flotation conduit fixing ring 10. The air flotation conduit mounting bracket 11 is fixed to the four side walls of the catering wastewater collection tank 7 by the fixing bracket with expansion bolts 12.
[0018] The high-pressure air flotation device 2 provides high-pressure gas, which enters the air flotation distributor connecting hose 4 through the high-pressure air flotation outlet pipe 3, and then further enters the air flotation distributor 5. The air flotation distributor 5 then evenly disperses the high-pressure gas through the air flotation conduit connecting hose 8 and enters each of the high-efficiency oil-gathering air flotation conduits 9 fixed around the catering wastewater collection tank 7. The high-pressure gas is sprayed out from each of the high-efficiency oil-gathering air flotation conduits 9 evenly distributed around the catering wastewater collection tank 7 to the side walls of the catering wastewater collection tank 7, forming high-pressure air flotation around the catering wastewater collection tank 7, which pushes the floating oil around the tank to move and accumulate in the middle of the collection tank.
[0019] This patent application embodies a systematic technology composed of multiple components. It uses a high-pressure air flotation device to provide high-pressure gas. The high-pressure gas is supplied through a high-pressure air flotation outlet pipe and connected to an air flotation distributor via a connecting hose. The high-pressure gas entering the air flotation distributor then enters the air flotation conduit through a connecting hose connected to the air flotation conduit. Finally, the air flotation conduit sprays the evenly distributed high-pressure gas onto the surrounding side walls of the water collection tank, forming a high-pressure air flotation that pushes the floating oil around the water collection tank towards the center of the water collection tank, thereby preventing the floating oil from accumulating on the surrounding side walls and causing the phenomenon of wall adhesion.
