Description

Soil oil floatation device

The present invention relates to a floating device, and more particularly to a soil oil floating device suitable for scraping free oil in a contaminated soil.

With the rapid development of industry, the waste generated by related industries may cause different levels of oil pollution in the soil, making soil pollution more serious. With the growing awareness of protecting the earth and the increasingly stringent laws and regulations, soil pollution is gradually being taken seriously. And become an important part of environmental protection work.

Soil pollution can be divided into heavy metal pollution, oil pollution and other pollution (such as polychlorinated biphenyls). The current treatment methods include departure treatment (burial, solidification, stabilization, heat treatment, etc.) and local treatment (pickling, washing). ) A series of processing procedures to achieve the goals of reduction, stability, harmlessness, and resource utilization.

When the oil contaminates the soil, it can be treated by physical washing or chemical washing to clean the contaminated soil, so that the concentration of the pollutant can be reduced to the treatment standard to reduce the harm to the human body and the environment. In the case of chemical washing, water and surfactants are added to the contaminated soil to promote the interaction of the oil and water molecules, making the oil easier to clean. In addition, the cost of using surfactants to remove oil for a long time is very high, and the treatment of subsequent wastewater is also a major problem, and it is not economical.

The contaminated soil is treated by physical washing, and the contaminated soil and water are stirred in a mixing tank of the flotation machine, so that the oil in the contaminated soil floats above the mixing tank and then scraped off. Since the device uses a rotating device to drive the turntable under the mixing drum to form a disturbance, the mixing solution is lifted to the surface of the mixing drum to scrape off the surface grease, and the opportunity to contact the oil in the process is increased above the mixing tank. The gas is mixed to increase the contact between the oil and the bubble. However, the mixed solution located below cannot reach the top of the mixing tank in a short time, which will directly affect the chance of contact between the oil and the bubble, and cannot achieve the purpose of separating the oil from the soil.

All of the above shortcomings show various problems arising from the treatment of existing wastes. The long-term failure will lead to the lack of cost efficiency. If you want to implement the soil pollution treatment process, the most important issue is to develop an economical and efficient treatment method.

The contaminated soil contains contaminated soil and water, and water is added to the soil for mixing, and the mixing ratio of the soil to water is 1:3.

The driving unit 2 includes a main shaft 21 disposed on the fixing frame 15 and extending into the processing tank 11, a pulley 22 connected to the main shaft 21, a first power source 23 connected to the pulley 22, and a first power source 23 a rotating wheel 24 disposed on the main shaft 21 and located in the accommodating space 10, wherein the main shaft 21 is in communication with the rotating wheel 24, wherein the rotating wheel 24 has an upward plane, and The rotating surface of the rotating blade is provided below.

The main shaft 21 has a shaft body 211 and a hollow flow passage 212 formed at the center of the shaft body 211. When the first power source 23 is actuated, the pulley 22 is driven and the main shaft 21 is interlocked. The rotating wheel 24 on the 21 will rotate accordingly, and the outside air is sucked into the hollow flow channel 212 and enters the accommodating space 10 via the rotating wheel 24, and then the air is broken into small by the rapidly rotating rotating wheel 24. The bubbles cause the fine bubbles to combine with the free oil of the contaminated soil, and the light free oil is driven by the fine bubbles to quickly float upward on the upper surface of the treatment tank 11.

The scraping unit 3 includes a processing unit 11 disposed on the processing tank 11 A second power source 31, and a squeegee set 32 connected to the second power source 32 and located on the opening 14.

The oil collecting groove on the side of the processing tank 11 is disposed near the squeegee group 32, and the second power source 32 is actuated to drive the squeegee set 32 to rotate to dispose the free oil on the upper surface of the processing tank 11. The product is scraped off and stored in the oil collection tank 16.

Furthermore, the squeegee assembly 32 has a pivot shaft 321 connected to the second power source 31, a rotating bracket 322 connected to the pivot shaft 321 , and a scraping detachably disposed on the rotating bracket 322 . The second squeegee 323 is oppositely connected to the front and rear ends of the rotating bracket 322. When the squeegee set 32 is rotated, the second scraping blade 323 is used to scrape the upper surface of the processing tank 11. The oil is free and the squeegee set 32 is continuously actuated.

In addition, the squeegee assembly 32 further has a plurality of first fixing holes 324 disposed on the rotating bracket 322, a plurality of second fixing holes 325 disposed on the two scraping pieces 323 at different heights, and a plurality of The first and second fixing holes 324 and 325 are fixed to the fixing member 326.

The contaminated soil enters the accommodating space 10 from the inlet port 12, and flows out to the discharge port 13 through the liquid level channel 54 after the completion of the treatment, because of the free oil of the contaminated soil to be treated in each batch, The concentration is different. In actual implementation, the height of the contaminated soil in the accommodating space 10 can be adjusted according to the site conditions to meet different actual needs.

In actual implementation, the two soil oil floatation devices may be connected in series, that is, the discharge port 13 of the first-order soil oil product floating device and the second-order soil oil product floating device. The inlet port 12 is docked to connect the two accommodating spaces 10, and since the set height of the discharge port 13 is lower than the inlet port 12, the position of the soil oil floating device located at the first position will be The soil oil floating device higher than the second order makes it a high to low height, and of course, more than two soil oil floating devices can be connected in series to meet different usage requirements.

During the process, the discharge port 13 of the first position flows to the inlet port 12 of the second position to enter the accommodating space 10 of the second position, so that the contaminated soil removes the free oil again, thereby improving the cleanliness of the soil. By developing this new economical and efficient treatment method, the willingness to carry out the treatment of contaminated soil will be enhanced.

In summary, the novel soil oil floating device, The main unit 1, the driving unit 2, the scraping unit 3, the bubble generating unit 4, and the liquid level adjusting unit 5 are arranged to each other, and the small oil is added to the accommodating space 10 to drive the free oil. The product rapidly rises to the upper surface of the treatment tank 11, and the scrap oil is used to scrape the free oil product to the oil collection tank 16 to separate the free oil from the soil. There is no need to add a surfactant to chemically react with the free oil to achieve the effect of quickly floating the surface of the free oil, so that the environment can be satisfied without polluting the environment, so the purpose of the novel can be achieved.

However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change and modification made by the novel patent application scope and the novel description content, All remain within the scope of this new patent.
