Specific embodiments

[0021] 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.

[0022] The following is a further detailed description of the present utility model in conjunction with the attached Figures 1 - 5 figures.

[0023] Please refer to Figures 1 - 5 , an embodiment of a dehydration tank for waste mineral oil recovery provided by the present utility model: A dehydration tank for waste mineral oil recovery includes a separation tank 1. One end of the separation tank 1 is welded with a feed pipe 2, and the feed pipe 2 is used to introduce the preliminarily treated waste mineral oil into the separation tank 1. The bottom end of the separation tank 1 is welded with a discharge pipe 3, and the discharge pipe 3 is used to discharge water and oil. A filter plate 5 is fixed to the inner wall of the separation tank 1 by bolts, and the filter plate 5 is used to filter impurities mixed in the mineral oil; An extrusion mechanism 4 is arranged at the top of the separation tank 1 and extends into the separation tank 1. The extrusion mechanism 4 is used to fully discharge the mineral oil and clean the inner wall of the separation tank 1. The extrusion mechanism 4 includes an extrusion seat 403 arranged inside the separation tank 1. The extrusion seat 403 is located above the filter plate 5. A sponge rod 406 is arranged inside the separation tank 1. The sponge rod 406 is located below the filter plate 5. The outer wall of the sponge rod 406 is attached to the inner wall of the separation tank 1. When the extrusion seat 403 moves downward, it can extrude the impurities filtered at the top of the filter plate 5, and then extrude the mineral oil adhered to the surface of the impurities to below the filter plate 5. When the sponge rod 406 moves downward, it can scrape the inner wall of the separation tank 1, and then scrape off the mineral oil adhered to the inner wall of the separation tank 1;

[0024] An electric telescopic rod 401 is provided at the top of the separation tank 1. The output end of the electric telescopic rod 401 is connected with a moving rod 402 through a coupling. The bottom end of the moving rod 402 penetrates into the interior of the separation tank 1, and the bottom end of the moving rod 402 is connected with an extrusion seat 403. When the output end of the electric telescopic rod 401 moves downward, it can drive the moving rod 402 to move downward. The movement of the moving rod 402 can drive the extrusion seat 403 to move downward, thereby squeezing the impurities filtered at the top of the filter plate 5; the bottom end of the moving rod 402 is fixedly connected with the extrusion seat 403 through bolts, and a through groove matching the movement track of the moving rod 402 is opened at the top of the separation tank 1. The through groove is used to ensure the stability of the vertical movement of the moving rod 402, and thus can stably drive the extrusion seat 403 to move downward when the moving rod 402 moves; a support frame 4011 is fixedly installed on the outer wall of the electric telescopic rod 401 through bolts, and the bottom end of the support frame 4011 is fixedly connected with the top of the separation tank 1 through bolts. The support frame 4011 is used to support the electric telescopic rod 401, thereby ensuring the stability of the electric telescopic rod 401 during operation;

[0025] A sliding rod 404 is provided at the bottom end of the extrusion seat 403. The bottom end of the sliding rod 404 penetrates below the filter plate 5. Two connecting rods 405 are welded on the outer wall of the sliding rod 404. The two connecting rods 405 are symmetrically distributed at both ends of the sliding rod 404. One end of the connecting rod 405 is fixedly connected with a sponge rod 406. Thus, there are two sponge rods 406, and the distribution of the two sponge rods 406 can form a circular ring. When the extrusion seat 403 moves downward, it can drive the sliding rod 404 to move downward. The downward movement of the sliding rod 404 can drive the connecting rod 405 to move. The movement of the connecting rod 405 can drive the sponge rod 406 to move, thereby scraping the mineral oil adhering to the inner wall of the separation tank 1; a sliding groove is opened inside the filter plate 5, and the sliding groove matches the movement track of the sliding rod 404. Through the setting of the sliding groove, the stability of the vertical movement of the sliding rod 404 can be ensured; the sliding rod 404 is connected with the extrusion seat 403 through bolts, and the connecting rod 405 is connected with the sponge rod 406 through bolts. Through the setting of this structure, when the sliding rod 404 moves vertically, it can stably drive the connecting rod 405 and the sponge rod 406 to move; an extrusion ring 101 is welded on the inner wall of the separation tank 1. The extrusion ring 101 is circular, and the inner diameter of the extrusion ring 101 is smaller than the outer diameter of the circular ring formed by the two sponge rods 406. Through the setting of this structure, after the sponge rod 406 moves downward and contacts the extrusion ring 101, the extrusion ring 101 can squeeze the sponge rod 406, thereby squeezing out the mineral oil adsorbed inside the sponge rod 406.

[0026] Working principle: When in use, first introduce the pre-treated waste mineral oil into the separation tank 1 through the feed pipe 2. After the waste mineral oil enters the interior of the separation tank 1, it comes into contact with the filter plate 5. The filter plate 5 can filter the impurities in the waste mineral oil. The filtered impurities accumulate at the top of the filter plate 5, and the waste mineral oil mixed with water deposits below the filter plate 5 through the filter plate 5. Due to the different densities of water and oil, when water and oil are static, they are stratified, with water below the oil. The water can be discharged through the discharge pipe 3. After the water is discharged completely, the oil can be discharged, thus performing the dehydration operation of the waste mineral oil;

[0027] Secondly, after the waste mineral oil is discharged from the interior of the separation tank 1, control the electric telescopic rod 401 to work. When the output end of the electric telescopic rod 401 moves downward, it can drive the moving rod 402 to move. The movement of the moving rod 402 drives the extrusion seat 403 to move downward. The extrusion seat 403 moves and squeezes the impurities filtered at the top of the filter plate 5, thereby squeezing out the oil adhered to the surface of the impurities. The squeezed oil drops to the lower part inside the separation tank 1 through the filter plate 5. And when the extrusion seat 403 moves downward, it drives the sliding rod 404 to move downward. The movement of the sliding rod 404 drives the connecting rod 405 to move downward. The movement of the connecting rod 405 drives the sponge rod 406 to move downward. The sponge rod 406 moves and scrapes against the inner wall of the separation tank 1 to absorb the mineral oil adhered to the interior of the separation tank 1. When the sponge rod 406 moves to contact the extrusion ring 101, the inner wall of the extrusion ring 101 squeezes the sponge rod 406, causing the sponge rod 406 to deform, and then squeezing out the oil adsorbed inside the sponge rod 406. Thus, the waste mineral oil can be discharged for the second time, improving the discharge effect of the oil in the waste mineral oil;

[0028] Finally, through the setting of the filter plate 5, the impurities mixed in the oil can be filtered, ensuring the purity of the oil during the dehydration process. At the same time, by squeezing the impurities with the extrusion seat 403, the oil adhered to the surface of the impurities can be squeezed, enabling the oil to be fully discharged, improving the discharge effect of the oil in the waste mineral oil. And through the setting of the same power source, the sponge rod 406 can scrape the inner wall of the separation tank 1 to discharge the oil adhered to the inner wall of the separation tank 1, further improving the discharge effect of the oil in the waste mineral oil.
