Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil-water treatment, and in particular to an oil-water separation and treatment device. Background Technology
[0002] Oil-water separation mainly relies on the density difference or chemical properties of water and oil, using the principle of gravity sedimentation or other physicochemical reactions to remove impurities or separate oil and water. The application of oil-water separation technology is becoming increasingly widespread, and it is increasingly used in fields such as petrochemicals, sewage treatment, and even laboratory waste discharge. On the one hand, it can recover resources, and on the other hand, it can avoid unnecessary environmental pollution. It is also widely used in the treatment of catering wastewater.
[0003] Although there are existing oil-water separation equipment, current oil-water separation efficiency is low and the separation is incomplete. In order to improve the separation efficiency, chemical agents are added, which will cause secondary pollution to the environment. Utility Model Content
[0004] The purpose of this invention is to design an oil-water separation device to solve the above-mentioned problems.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] Oil-water separation treatment device, including:
[0007] Separation chamber for oil-water separation;
[0008] Oil collection box; the oil collection box is located in the separation chamber;

[0010] Oil collecting chamber; the inlet of the oil collecting chamber is connected to the outlet of the oil pump;
[0011] Water collection box; the water collection box is fixedly installed at the lower end of the separation chamber;
[0012] Water collection chamber; the water collection chamber is connected to the water collection box via an outlet pipe;
[0013] Position control unit; The control unit is used to control the height of the oil collection box and the opening and closing of the water collection box outlet. When the oil pump starts pumping oil, the height of the highest point of the oil layer is higher than the height of the oil collection box. The height of the oil-water boundary line is located between the upper and lower ends of the oil collection box. When the outlet of the water collection box is opened, the height of the oil-water boundary line is higher than the height of the water collection box.
[0014] The beneficial effects of this invention are as follows: by fixing the oil collection box to the float, and under the action of overall buoyancy and gravity, the highest point of the oil layer is higher than the height of the oil collection box, and the oil-water boundary is located between the upper and lower ends of the oil collection box. At this time, the oil collection box is full of oil, which can be pumped out by an oil pump. When the sewage in the separation chamber reaches a certain height, the outlet of the water collection box opens, and the sewage can enter the water collection chamber from the water collection box. This device achieves thorough oil-water separation and high oil-water separation efficiency, and does not add chemical agents, so it will not cause secondary pollution to the environment.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, the oil-water separation treatment device includes:
[0028] Separation chamber 4 for oil-water separation;
[0029] Oil collection box 25; Oil collection box 25 is installed inside separation chamber 4;
[0030] Oil pump 10; the inlet of oil pump 10 is located inside the oil collection box 25;
[0031] Oil collecting chamber 8; the inlet of oil collecting chamber 8 is connected to the outlet of oil pump 10;
[0032] Water collection box 20; Water collection box 20 is fixedly installed at the lower end inside the separation chamber 4;
[0033] Water collection chamber 9; Water collection chamber 9 is connected to water collection box 20 through water outlet pipe 23;
[0034] Position control component; The control component is used to control the height of the oil collection box 25 and the opening and closing of the outlet of the water collection box 20. When the oil pump 10 starts pumping oil, the height of the highest point of the oil layer 5 is higher than the height of the oil collection box 25. The height of the oil-water boundary line 6 is located between the upper and lower ends of the oil collection box 25. When the outlet of the water collection box 20 is opened, the height of the oil-water boundary line 6 is higher than the height of the water collection box 20.
[0035] Position control components include:
[0036] Float 11; The density of float 11 is less than that of water and greater than that of oil, and oil collection box 25 is fixedly installed on float 11;
[0037] Block 22; Block 22 is located directly above the outlet of water collection box 20;
[0038] Connecting rod; the first end of the connecting rod is fixedly connected to the plug 22;
[0039] Connecting plate 19; Connecting plate 19 is fixedly connected to the second end of the connecting rod;
[0040] Connecting slider 18; a slide rail 16 is provided in the separation chamber 4, the connecting slider 18 is slidably installed in the slide rail 16, and the connecting slider 18 is fixedly connected to the connecting plate 19.
[0041] Flexible connecting line 17; both ends of the flexible connecting line 17 are fixedly connected to the float 11 and the connecting plate 19, respectively;
[0042] Elastic element; the two elastic ends of the elastic element act on the connecting plate 19 and the water collection box 20 respectively, and the direction of the force exerted by the elastic element on the connecting plate 19 is the direction from the second end of the connecting rod towards the first end.
[0043] The position control component also includes a mounting plate 12 and a mounting slider 12. The mounting plate 12 is fixedly connected to the mounting slider 12, and the mounting slider 12 is slidably mounted in the slide rail 16.
[0044] A silicone sleeve is fitted on the connecting slider 18. The silicone sleeve increases the friction between the connecting slider 18 and the slide rail 1, preventing the oil-water boundary line 6 from dropping. As a result, the connecting plate 19, connecting rod and block 22 will drop under the action of the tension spring 21, blocking the outlet of the water collection box 20, causing a large amount of sewage in the separation chamber 4 to be unable to be discharged.
[0045] The position control component also includes a pressure frame 15, which is fixedly installed at the lower end of the mounting plate 12 and is located between the connecting plate 19 and the mounting plate 12.
[0046] The elastic element is a tension spring 21, which is fitted onto the connecting rod. The two ends of the tension spring 21 are fixedly connected to the lower end of the connecting plate 19 and the lower end of the water collection box 20, respectively. The tension spring 21 is always in a charged state.
[0047] The oil-water separation treatment device also includes a baffle plate 3, which is fixedly installed in the separation chamber 4. A water inlet pipe 1 is installed at the inlet of the separation chamber 4. The water inlet pipe 1 is located on the first side of the baffle plate 3. The oil collection box 25, the water collection box 20, and the position control component are located on the second side of the baffle plate 3. The water inlet pipe 1 is located at the lower end of the separation chamber 4. Through the position design of the baffle plate 3 and the water inlet pipe 1, the oil-water and sewage in the separation chamber 4 are prevented from directly entering the oil collection box 25, which would cause sewage to remain in the oil collection box 25 and result in incomplete oil-water separation.
[0048] The water-oil separation treatment device also includes a counterweight 14 and an oil suction pipe. The counterweight 14 is fixedly installed at the first end of the oil suction pipe, and the second end of the oil suction pipe is connected to the inlet of the oil pump 10. The counterweight 14 is placed in the oil collection box 25. Under the action of the counterweight 14, the second end of the oil suction pipe is always located at the bottom of the oil collection box 25. Under the buoyancy and gravity of the counterweight 14, the oil collection box 25 and the float 11, the height of the oil-water boundary line 6 is located between the upper and lower ends of the oil collection box 25.
[0049] The working principle of this oil-water separation treatment device is as follows:
[0050] During water-oil-sewage separation, the inlet valve 2 is opened, and a water pump is used to allow the water-oil-sewage to enter the separation chamber 4. Under the action of the baffle 3, the water-oil-sewage spreads from the first side of the baffle 3 to the second side of the baffle 3, and the overall liquid level in the separation chamber 4 increases. When the height of the oil layer 5 is higher than the highest height of the oil collection box 25, the oil enters the oil collection box 25. At this time, the oil in the oil collection box 25 can be pumped into the oil collection chamber 8 by the oil pump 10. When the oil-water boundary line 6 rises to a certain level, the flexible connecting line 17 is taut, so that the connecting plate 19 receives the tension of the flexible connecting line 17, which drives the block 22 of the connecting rod to rise, so that the outlet of the oil collection box 25 opens, and the water enters the water collection chamber 9 through the water outlet pipe 23 and the water outlet valve 24, thus achieving the ability to collect water.
[0051] When the oil-water boundary 6 drops to a certain level, the pressure frame 15 contacts the connecting plate 19 and exerts pressure on the connecting plate 19. Under the action of the tension spring 21, the connecting plate 19 drives the connecting rod and the block 22 to drop in height. The block 22 blocks the opening of the water collection box 20, preventing the oil-water boundary 6 from dropping continuously and the oil from entering the water collection chamber 9 through the opening of the water collection box 20.
[0052] The technical solution of this utility model is not limited to the specific embodiments described above. All technical modifications made based on the technical solution of this utility model shall fall within the protection scope of this utility model.
