DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution: a distillation column for waste mineral oil recovery, including a distillation column body 1, an air outlet pipe 2, a discharge pipe 3, a feed pipe 4, an oil extraction pipe 5, a heating mechanism 6, a condenser pipe 7, a cooling box 8, a cooling water outlet pipe 9, a cooling water inlet pipe 10, a cover plate 11, a sealing gasket 12, a positioning arm 13, a limiting mechanism 14, a knob 1401, a clamping block 1402, and a clamping sleeve 15. The upper and lower ends of the distillation column body 1 are respectively provided with an air outlet pipe 2 and a discharge pipe 3, and the side of the distillation column body 1 is successively installed with a feed pipe 4, an oil extraction pipe 5, and a heating mechanism 6. The upper end of the air outlet pipe 2 is fixedly connected with a condenser pipe 7, and the outer wall of the condenser pipe 7 is fixedly installed with a cooling box 8. The upper and lower sides of the end face of the cooling box 8 are respectively provided with a cooling water outlet pipe 9 and a cooling water inlet pipe 10. The upper inner wall of the cooling box 8 is movably connected with a cover plate 11, and both ends of the upper surface of the cover plate 11 are fixedly provided with clamping sleeves 15. The upper ends of both end faces of the cooling box 8 are respectively provided with positioning arms 13, and the inner wall of the end of the positioning arm 13 is installed with a limiting mechanism 14.

[0025] The shape of the condenser pipe 7 inside the cooling box 8 is set to a spiral shape, which is convenient for increasing the contact area between the condenser pipe 7 and the cooling water, thereby improving the condensation effect of the device.

[0026] The cooling box 8 and the cover plate 11 are slidably connected, which is convenient for the user to move the cover plate 11 for disassembly and assembly of the cover plate 11.

[0027] The outer wall of the cover plate 11 is fixedly installed with a sealing gasket 12, and the sealing gasket 12 is arranged in a fitting manner with the cooling box 8. When the user installs the cover plate 11, the cover plate 11 drives the sealing gasket 12 to fit the cooling box 8, thereby improving the sealing performance of the cooling box 8.

[0028] The positioning arm 13 and the cooling box 8 form a rotating structure, which is convenient for the user to rotate the positioning arm 13, so that the limiting mechanism 14 is away from the cooling box 8, thereby avoiding the limiting mechanism 14 from affecting the opening of the cover plate 11 and avoiding the limiting mechanism 14 from affecting the user's cleaning of the scale on the surface of the condenser pipe 7.

[0029] The limiting mechanism 14 includes a knob 1401 and a clamping block 1402. The knob 1401 is movably installed on the inner wall of the positioning arm 13, and the end of the knob 1401 is movably connected with the clamping block 1402, which is convenient for making the cooling box 8 and the cover plate 11 in a relatively stable state through the limiting mechanism 14.

[0030] The knob 1401 is threadedly connected to the positioning arm 13, and the knob 1401 and the clamping block 1402 are rotatably arranged, facilitating the user to rotate the knob 1401, so that the knob 1401 moves relative to the positioning arm 13, thereby driving the clamping block 1402 to move.

[0031] The clamping block 1402 and the clamping sleeve 15 are slidably arranged, facilitating the clamping block 1402 to move and insert into the clamping sleeve 15, thereby limiting the cover plate 11.

[0032] Working principle: When using the distillation tower for waste mineral oil recovery, first as Figures 1-5 shown, the user introduces the waste mineral oil in the light removal tower into the distillation tower body 1 through the feed pipe 4. At the same time, the user starts the heating mechanism 6 to heat the waste mineral oil. At this time, the fuel oil in the waste mineral oil evaporates and separates from the waste mineral oil, and the fuel oil gas is discharged from the device through the air outlet pipe 2. Then, when the distillation of the waste mineral oil is completed, the user starts the oil extraction pipe 5 to introduce the base oil in the waste mineral oil into the subsequent processing equipment. Next, the user opens the discharge pipe 3 to discharge the remaining part of the waste mineral oil from the device, thus completing the distillation and recovery of the waste mineral oil. Then, when the distillation tower body 1 is working, the user starts the cooling water inlet pipe 10. At this time, the cooling water enters the cooling box 8 and is discharged from the cooling water outlet pipe 9. Then, when the fuel oil gas enters the condensing pipe 7 through the air outlet pipe 2, the cooling water cools the fuel oil gas flowing in the condensing pipe 7. At this time, the fuel oil gas condenses in the condensing pipe 7 and then flows out of the condensing pipe 7. When the scale accumulates on the surface of the condensing pipe 7 and needs to be cleaned, the user shuts down the device. Then, the user rotates the knob 1401. Next, the knob 1401 moves relative to the positioning arm 13. Subsequently, the knob 1401 drives the clamping block 1402 to disengage from the clamping sleeve 15. Similarly, operate the remaining limiting mechanism 14. Then, the user rotates the positioning arm 13 respectively to drive the limiting mechanism 14 away from the cooling box 8. Next, the user moves the cover plate 11 upward so that the cover plate 11 and the sealing gasket 12 disengage from the cooling box 8, thereby completing the opening of the cooling box 8, and further facilitating the user to clean the scale on the surface of the condensing pipe 7. Therefore, the device is convenient to open its condensing structure, thus facilitating the user to clean the scale on the surface of the condensing pipe 7, improving the practicability of the device.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
