Description

Technical Field

[0001] The utility model relates to the technical field of new energy and energy-saving, and in particular to a device for improving the extraction efficiency of waste mineral oil. Background Art

[0002] Waste mineral oil is extracted and refined from petroleum, coal, and oil shale. During the process of mining, processing, and use, the original physical and chemical properties have been changed due to external factors. The mineral oil that can no longer be used is a complex mixture composed of various substances. Various components in them are toxic and harmful to the human body. Therefore, if waste mineral oil is not handled properly, once it enters the external environment in large quantities, it will cause serious environmental pollution. At present, filtration and extraction are usually used on the market to pre-treat waste mineral oil.

[0003] For example, a Chinese patent discloses a waste mineral oil filtering device with waste gas collection, including a distillation kettle, a purification and extraction device is provided on one side of the distillation kettle, a filtration and separation chamber is provided at the bottom of the purification and extraction device, an absorption tank is provided on one side of the top of the filtration and separation chamber, a condensation chamber is provided on the side of the top of the filtration and separation chamber away from the absorption tank, a distillation chamber is provided inside the distillation kettle, a sealing cover is fixedly connected to the top of the distillation kettle by screws, and a gas outlet pipe is fixedly connected to the top of the sealing cover. The utility model can realize the rapid connection and disassembly of the gas outlet pipe and the gas inlet pipe through the first connector and the second connector at both ends of the connecting pipe. After the gas generated by distillation enters the absorption tank, the absorption liquid absorbs the toxic and harmful gases mixed therein. After the absorption liquid is saturated, the water outlet pipe is opened to release the saturated absorption liquid, and at the same time, the water inlet pipe is opened to inject new absorption liquid into the absorption tank to realize the collection of waste gas.

[0004] The above patent still has certain defects. This patent collects waste gas by absorbing toxic and harmful gases mixed in it through absorption liquid. During the extraction process, it is necessary to add extraction agent to complete the extraction process. However, the extraction liquid is added to the material in the same place through a pipeline, resulting in a small contact area with the material. It is unable to fully contact the material. It takes a long time to diffuse and contact the entire material, resulting in a decrease in extraction efficiency. Utility Model Content

[0033] The upper surface of the liquid supply box 209 is provided with a liquid injection port, and the internal thread of the liquid injection port is connected with a closed cover, which is convenient for the staff to open the liquid supply box 209 to replenish the extraction liquid inside the liquid supply box 209.

[0036] See also Figure 3In order to prevent the leaked material from spilling onto the ground, the bearing mechanism 7 in this embodiment includes two limit blocks 701, two sliders 702, a bearing box 703, two limit springs 704 and two fixed plates 705. The two fixed plates 705 are fixed to the lower surface of the extraction box 1. The two sliders 702 are respectively slidably connected to the inside of the two fixed plates 705.

The front sides of the two fixed plates 705 are provided with sliding grooves for the slider 702 to slide and connect.

[0038] It should be noted that the supporting mechanism 7 collects the remaining materials in the discharge pipe that will continue to drip through the supporting box 703 to prevent them from dripping directly onto the ground and causing waste. It also prevents the leaked materials from directly spilling onto the ground and causing waste when collecting the materials.

[0039] The working principle of the above embodiment is:

[0040] (1) When it is necessary to add extraction liquid to the material, the electric push rod 205 is started. The electric push rod 205 drives the movable plate 204 to move to the right and drives the baffle plate 203 to move together. When the baffle plate 203 is in contact with the left side of the auxiliary box 201, the electric push rod 205 is closed. At this time, the first infusion hole on the movable plate 204 is aligned with the second infusion hole on the material box. The extraction liquid in the auxiliary box 201 flows into the material box through the first infusion hole and the second infusion hole to contact the material. At the same time, it contacts the material at different positions through multiple second infusion holes, and makes the material contact with all materials more quickly during the stirring process, thereby accelerating the extraction efficiency. The feeding mechanism 2 cooperates with the auxiliary box 201, the baffle plate 203, the movable plate 204 and the electric push rod 205 so that the extraction liquid can contact with a larger area of ​​the material when dripping, so that the material in the material box can contact with the extraction liquid faster to complete the extraction work, thereby improving the extraction efficiency.

[0041] (2) The extracted materials flowing out of the discharge pipe will continue to drip because the discharge pipe is not closed tightly or there is residue in the discharge pipe. These extracted materials will drip into the inside of the carrying box 703. When the materials in the carrying box 703 need to be processed, the carrying box 703 is pulled forward. The carrying box 703 drives the two sliders 702 to move forward together and gradually separate from the limit block 701. When the sliders 702 completely slide out of the two fixed plates 705, the carrying box 703 can be taken out to clean the extraction liquid inside. The carrying mechanism 7 collects the residual materials in the discharge pipe that will continue to drip together through the carrying box 703 to prevent them from dripping directly onto the ground and causing waste. At the same time, it also prevents the leaked materials from directly spilling onto the ground and causing waste when collecting the materials.
