[0002] Oily sludge refers to sludge mixed with heavy oils such as crude oil, various refined oils, and residual oils. It does not exist inherently in nature, but is formed due to various activities related to crude oil and refined oils in oilfield exploitation, petroleum refining processes, transportation, use, storage, etc., such as various accidents, improper operations, old, damaged, and corroded equipment, resulting in the running, overflowing, dripping, and leakage of crude oil and refined oils, which leak to the ground, deposit in the ocean, lakes, and river bottoms, and are mixed with soil, water, etc. to form a mixture of oil, soil, water, and even mixed with other pollutants. When treating existing oily sludge, a demulsifier is mostly added to separate it into an oil layer, a water layer, and a mud layer. However, for existing equipment, after separating oil, water, and mud, it is not easy to take out, especially the dirt in the mud layer. Therefore, it is necessary to develop a demulsification and separation device that is convenient for separately taking out oil, water, and mud to meet the needs. Content of the Utility Model

[0018] The present utility model will be further described below in conjunction with the attached drawings.

[0019] As Figures 1-4 shown, an oil-containing sludge demulsification and separation device includes a tank body 1. A feed inlet 6 is connected to the top of the tank body 1. A crushing chamber 4 is connected between the tank body 1 and the feed inlet 6. A chemical inlet 2 communicates with the upper part of the tank body 1. A first electric module 7 is fixedly connected to the top of the tank body 1. A first carrier 9 is connected to the moving terminal of the first electric module 7. A fuel pump 8 is connected to the first carrier 9. The inlet of the fuel pump 8 is connected to an oil suction pipe 10 which is slidably arranged in the tank body 1. A second electric module 15 is obliquely downwardly connected to the side of the tank body 1. A second carrier 17 is connected to the moving terminal of the second electric module 15. A water pump 18 is fixedly connected to the second carrier 17. The inlet of the water pump 18 is connected to a water suction pipe 16 which is slidably arranged in the tank body 1. A conveyor 20 is connected to the bottom of the tank body 1. An auger 24 is rotatably connected in the conveyor 20. A discharge hole 1b is formed at the bottom 1a of the tank bottom of the tank body 1. The auger 24 is located below the discharge hole 1b. The auger 24 is controlled by an auger motor 19. A material outlet 22 is provided at the bottom of the conveyor 20. A material valve 21 is arranged at the material outlet 22.

[0020] In order to improve the demulsification rate by stirring, a stirring motor 25 is fixedly connected to the side of the tank body 1. A stirring shaft 13 is rotatably connected in the tank body 1. A stirring frame 12 is fixedly connected to the stirring shaft 13. The stirring shaft 13 is controlled by the stirring motor 25.

[0021] In order to prevent impurities from being sucked in, a first filter screen 11 is connected to the end of the oil suction pipe 10, and a second filter screen 14 is connected to the end of the water suction pipe 16.

[0022] In order to crush the sludge, a main crushing roller 5 and a secondary crushing roller 26 are rotatably connected inside the crushing chamber 4. The main crushing roller 5 is controlled by a main crushing motor 3, and the secondary crushing roller 26 is controlled by a secondary crushing motor 27.

[0023] In order to improve stability, a support 23 is fixedly connected to the bottom of the tank body 1.

[0024] In order to observe the stratification situation and height, a transparent observation window 28 is provided on the side of the tank body 1.

[0025] The specific working process of the present utility model is as follows:

[0026] During operation, oily sludge is fed through the feed inlet 6. First, start the main crushing motor 3 and the auxiliary crushing motor 27 to drive the main crushing roller 5 and the auxiliary crushing roller 26 to work. When the oily sludge passes through the crushing chamber 4, it becomes finer. At this time, demulsifier is added through the chemical inlet 2, and the stirring motor 25 is turned on. The stirring shaft 13 drives the stirring frame 12 to rotate, and through stirring, the oily sludge and the demulsifier are evenly mixed to improve the reaction rate. After the reaction is completed, the layering situation inside the tank body 1 is observed through the observation window 28.

[0027] When sucking the upper oil layer, control the first electric module 7 to lower the first carrier 9, lower the oil suction pump 8 and the oil suction pipe 10 to suck the upper oil layer. When the oil layer is almost completely absorbed, stop the absorption. The first filter screen 11 plays a filtering role.

[0028] When sucking the water layer, the second electric module 15 drives the second carrier 17 to move, so that the water pump 18 drives the water suction pipe 16 to move obliquely upward inside the tank body 1 to suck out the water in the middle layer and the remaining oil stain in the upper layer. The second filter screen 14 plays a filtering role.

[0029] When taking out the mud layer, open the material valve 21 and turn on the auger motor 19. The mud layer enters the conveyor 20 through the discharge hole 1b at the bottom of the tank 1a and is taken away by the auger 24.
