[0002] Oil-water emulsion is an inhomogeneous system formed by a mixture of oil and water, in which oil droplets are dispersed in the water phase or water droplets are dispersed in the oil phase. The formation of oil-water emulsions is usually due to stirring, the presence of emulsifiers or other strong physical effects. According to the size and distribution of oil droplets and water droplets, they can be divided into two types: oil-in-water type (W / O) and water-in-oil type (O / W). In industrial production and daily life, oil-water emulsions are produced in many scenarios, such as oil extraction, chemical production, food processing, catering wastewater, etc. The separation of oil-water emulsions is usually difficult, and appropriate methods and equipment are required to achieve effective oil-water separation.

DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 14 The present invention provides a technical solution: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a separation tank 1, which is used for containing and treating the oil-water emulsion; A filtering mechanism 2, the filtering mechanism 2 is used for filtering impurities inside the oil-water emulsion; A heating mechanism 3, the heating mechanism 3 is used for heating the oil-water emulsion; A separation mechanism 4, the separation mechanism 4 is used for oil-water separation processing of the oil-water emulsion; The filtering mechanism 2 and the heating mechanism 3 are both fixedly mounted on the outside of the separation tank 1 , and the separation mechanism 4 is arranged directly above the separation tank 1 .

[0036] The filtering mechanism 2 includes a liquid inlet pipe 21, which is respectively inserted into the outside of the separation tank 1 and the built-in tube 40, and the inside of the liquid inlet pipe 21 is fixedly connected with a No. 1 filter screen 22 and a No. 2 filter screen 23, respectively. The top of the inner cavity of the liquid inlet pipe 21 is fixedly connected with a ring seat 24, and the inside of the ring seat 24 is rotatably connected with a force disk 25, and the outer side of the force disk 25 is fixedly connected with a connecting rod 26, and the end of the connecting rod 26 away from the force disk 25 is fixedly connected with a sliding blocking plate 28, and the sliding blocking plate 28 is inserted into the bottom of the inner cavity of the liquid inlet pipe 21.

[0037] A pressure relief assembly 27 is provided below the sliding plugging plate 28. The pressure relief assembly 27 includes a pressure relief pipe 271. The top of the pressure relief pipe 271 is plugged into the sliding plugging plate 28. The inside of the pressure relief pipe 271 is fixedly connected to a perforated plate 272. A plugging plate 275 is extruded and adapted on the outside of the perforated plate 272. A telescopic rod 274 is fixedly connected to one end of the plugging plate 275 close to the perforated plate 272. A support 273 is fixedly connected to the end of the telescopic rod 274 away from the plugging plate 275. The support 273 is fixedly connected to the The pressure relief pipe 271 is fixedly connected to the bottom of the inner cavity of the pressure relief pipe 271, and the bottom end of the pressure relief pipe 271 is respectively inserted into the outer side of the separation tank 1 and the inner tube 40, and then the oil-water emulsion is put into the top of the liquid inlet pipe 21. At this time, the oil-water emulsion will pass through the No. 1 filter 22 and the No. 2 filter 23 in turn and hit the force plate 25, wherein the No. 1 filter 22 and the No. 2 filter 23 are staggered, thereby increasing the filtering effect on the impurities inside the oil-water emulsion. The impacted force disk 25 will deflect inward through the ring seat 24, and the connecting rod 26 fixedly connected to the outer side of the force disk 25 will move inward with the sliding plugging plate 28 connected to its other end, so that the pressure relief pipe 271 originally blocked by the sliding plugging plate 28 will open, and then the oil-water emulsion will be divided into two parts, one part will pass through the force disk 25 into the built-in tube 40, and the other part will enter the pressure relief pipe 271, and then the oil-water emulsion inside the pressure relief pipe 271 will hit the plugging disk 275, and then the telescopic rod 274 fixedly connected to the outer side of the plugging disk 275 will stretch, causing the plugging disk 275 to move away from the perforated plate 272, and then the oil-water emulsion will pass through the perforated plate 272 into the built-in tube 40, and the force disk 25 will only deflect when too much oil-water emulsion flows in, and the oil-water emulsion will be divided into two parts for flow transmission, thereby achieving pressure relief treatment for the oil-water emulsion.

[0038] like Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the separation mechanism 4 includes a separation component 41, an inner connecting rod 42 is inserted into the surface of the separation component 41, a polymer membrane 43 is fixedly connected to the bottom of the inner connecting rod 42, the polymer membrane 43 is slidably adapted to the inner side of the separation tank 1, a top ring strip 44 is fixedly connected to the top of the inner connecting rod 42, an outer connecting rod 45 is arranged on the side of the inner connecting rod 42, and finally the inner connecting rod 42 and the outer connecting rod 45 are returned to their positions upwards. At this time, when the polymer membrane 43 fixedly connected to the bottom of the inner connecting rod 42 moves out from the top of the water layer, it will take away some of the residual oil for treatment, wherein the polymer membrane 43 is made of hydrophobic and lipophilic materials. The advantages of carrying out separation treatment in batches at the same time are: it is easy to optimize the process: the separation process of each batch can be used as an independent test, which is convenient for optimizing and improving the separation process parameters and improving the separation effect; the quality control is more accurate: batch processing makes the quality inspection and control of the oil and water after each batch of separation more accurate, ensuring the stability of product quality, and avoiding the problems of oil and water mixing caused by one-time separation. The external rod 45 is fixedly connected to the bottom of the top ring bar 44, and the outer side of the external rod 45 is slidably adapted with a friction block 46, and a fixed block 47 is arranged below the friction block 46. The external rod 45 is inserted in the top of the fixed block 47 and extends to the bottom. The outer side of the fixed block 47 is fixedly connected to the limiting plate 48, and the two ends of the limiting plate 48 are slidably adapted with vertical rails 49. The side of the vertical rail 49 away from the limiting plate 48 is fixedly connected with the internal pipe 40, and the internal pipe 40 is fixedly connected to the inner side of the separation tank 1. The external rod 45 is moved along the fixed block by external force or the operator. The inner part of 47 moves downward, and the friction block 46 slidably adapted on the outer side of the external rod 45 will contact the fixed block 47 and squeeze it downward, wherein the inner side of the friction block 46 is fixedly connected with a plurality of protrusions, so that the friction block 46 will move along with the external rod 45 during the downward movement, and move downward with the fixed block 47, and then the limiting plate 48 connected to the fixed block 47 will move downward along the vertical rail 49. However, when the fixed block 47 moves downward to the bottom of the vertical rail 49, the friction block 46 will still squeeze it downward, but the external rod 45 will pass through the friction block 46 and the fixed block 47 and continue to move downward, wherein the inner rod 42 fixedly connected to the bottom of the top ring strip 44 will move downward with the polymer membrane 43 fixedly connected to its bottom end until it moves to the bottom of the inner cavity of the separation tank 1, which not only serves to open the opening of the filter mechanism 2, but also serves to pre-treat the subsequent separation.

[0039] The heating mechanism 3 includes an upper insert plate 31, which is inserted into the interior of the separation tank 1. The bottom of the upper insert plate 31 is fixedly connected to an inclined pressure plate 32, and the bottom of the inclined pressure plate 32 is fixedly connected to an elastic frame 33. The bottom of the elastic frame 33 is fixedly connected to the outside of the separation tank 1. The inside of the elastic frame 33 is fixedly connected to a spring 34. A plug-in plate 35 is arranged on the side of the elastic frame 33. The plug-in plate 35 is fixedly connected to the bottom of the inclined pressure plate 32. A circular hole 36 is opened on the surface of the plug-in plate 35. The inner side of the plate 35 is slidably adapted with a transition pipe 37, and the end of the transition pipe 37 away from the interpenetrating plate 35 is fixedly connected with a guide plate 38, and the guide plate 38 is fixedly connected to the inside of the built-in pipe 40. The side of the interpenetrating plate 35 away from the transition pipe 37 is slidably adapted with an extension pipe 39, wherein the end of the extension pipe 39 away from the interpenetrating plate 35 is connected to an external heat transfer device, and the bottom of the extension pipe 39 is fixedly connected with a support rod 30, and the end of the support rod 30 away from the extension pipe 39 is fixedly connected to the separation tank 1 , and then the oil-water emulsion in the built-in tube 40 will flow downward and squeeze the inclined pressure plate 32. At this time, the inclined pressure plate 32 will move downward with the insertion plate 35. The elastic frame 33 fixedly connected to the bottom of the inclined pressure plate 32 during the downward movement is elastic, which prevents the oil-water emulsion from leaking out. Similarly, the upper insertion plate 31 fixedly connected to the top of the inclined pressure plate 32 also plays the same role. Then the circular holes 36 opened on the surface of the insertion plate 35 will coincide with the transition pipe 37 and the extension pipe 39 respectively. At this time, hot air will flow into the extension pipe 39 connected to the external heating equipment, and then the hot air will pass through the circular holes 36 and the transition pipe 37 in turn, and sprinkle on the drainage plate 38. At this time, the oil-water emulsion will be heated. Therefore, appropriately increasing the temperature can reduce the viscosity of the oil and reduce the oil-water interfacial tension, thereby accelerating the aggregation and floating of the oil droplets and accelerating the stratification. The temperature is between 20-50 degrees Celsius.

[0040] like Fig.11 , Fig.12 , Fig.13 and Fig.14As shown, the separation assembly 41 includes a No. 1 separation ring 411, a No. 2 separation ring 412 is arranged directly below the No. 1 separation ring 411, and a No. 3 separation ring 413 is arranged directly below the No. 2 separation ring 412. The surfaces of the No. 1 separation ring 411, the No. 2 separation ring 412 and the No. 3 separation ring 413 are all plugged into the inner connecting rod 42. A suction pipe 414 is arranged on the side of the No. 3 separation ring 413, and the suction pipe 414 is fixedly connected to the top of the separation tank 1. The top of the No. 1 separation ring 411 is fixedly connected to the No. 1 pull rod 415, and the surface of the No. 1 separation ring 411 is plugged with the No. 2 pull rod 416. Similarly, the No. 2 pull rod 416 is moved upward, so that the No. 2 separation ring 412 fixedly connected to its bottom will also move upward and enter the oil layer from the water layer. Layer, and at the same time, the remaining oil layer is over-halved, and the function of the No. 3 separation ring 413 is the same as that of the No. 1 separation ring 411, but it will separate the last remaining oil layer. Before the other three separation rings work separately, they all need to let the emulsion stand for a period of time before operating. The No. 2 pull rod 416 is fixedly connected to the top of the No. 2 separation ring 412, and the surfaces of the No. 1 separation ring 411 and the No. 2 separation ring 412 are both plugged with the No. 3 pull rod 417, and the No. 3 pull rod 417 is fixedly connected to the top of the No. 3 separation ring 413. The top of the No. 1 separation ring 411 is sleeved with a No. 1 air pipe 418, and the surface of the No. 1 separation ring 411 is plugged with a No. 2 air pipe 419, and the No. 2 air pipe 419 is sleeved on the top of the No. 2 separation ring 412. The surfaces of the No. 1 separation ring 411 and the No. 2 separation ring 412 are both plugged with the No. 3 air pipe 410, and the No. 3 air pipe 410 is sleeved on the top of the No. 3 separation ring 413. The No. 1 separation ring 411, the No. 2 separation ring 412 and the No. 3 separation ring 413 are all provided with inner perforations 4102, and the inner perforations 4102 are fixedly connected with hollow sheets 4103, and the ends of the hollow sheets 4103 away from the inner perforations 4102 are squeezed and adapted with tough sheets 4101, wherein the number of tough sheets 4101 is several, and they are respectively fixedly connected to the outer sides of the No. 1 separation ring 411, the No. 2 separation ring 412 and the No. 3 separation ring 413, and before the oil-water emulsion enters the interior of the separation tank 1, the No. 1 separation ring 411, the No. 2 separation ring 412 and the No. 3 separation ring 413 are respectively inserted into the separation tank 1. 2 and the third separation ring 413 move downward along the inner connecting rod 42 to the interior of the separation tank 1, and finally the oil-water emulsion enters the separation tank 1 completely and stands for a period of time. At this time, the No. 1 pull rod 415 is slowly moved upward by external force, so that the No. 1 separation ring 411 connected to the bottom thereof will move upward together, and then the No. 1 separation ring 411 will break through the water layer and enter the oil layer. When the No. 1 separation ring 411 enters about half of the oil layer, compressed gas is injected into the No. 1 air pipe 418. At this time, the compressed gas will enter the inner through hole 4102 opened in the No. 1 separation ring 411 through the No. 1 air pipe 418, and then the hollow sheet 4103 arranged inside the inner through hole 4102 will be filled with compressed gas.The flexible sheet 4101 expands outward quickly and pushes it away to be tightly attached to the inner wall of the No. 1 separation ring 411, and then the No. 1 pull rod 415 moves upward, so that part of the oil-water emulsion separated by the hollow sheet 4103 and the No. 1 separation ring 411 will be carried upward by the two, thereby achieving the initial separation and treatment of the oil-water emulsion.

[0041] When the present invention is in use: first, the external rod 45 is moved downward along the inside of the fixed block 47, and the friction block 46 slidably adapted on the outside of the external rod 45 will contact the fixed block 47 and squeeze it downward, wherein the inner side of the friction block 46 is fixedly connected with a plurality of protrusions, so that the friction block 46 will move downward with the fixed block 47, and then the limiting plate 48 connected to the fixed block 47 will move downward along the vertical rail 49, however, when the fixed block 47 moves downward to the bottom of the vertical rail 49, the friction block 46 will still squeeze it downward, but the external rod 45 will pass through the friction block 46 and the fixed block 47 and continue to move downward, wherein the internal rod 42 fixedly connected to the bottom of the top ring strip 44 will move downward with the polymer membrane 43 fixedly connected to its bottom end until it moves to the bottom of the inner cavity of the separation tank 1.

[0042] At this time, the oil-water emulsion is poured into the top of the liquid inlet pipe 21, and the oil-water emulsion will pass through the No. 1 filter 22 and the No. 2 filter 23 in turn, and hit the force-bearing disk 25. At this time, the force-bearing disk 25 that is hit will deflect inward through the ring seat 24, and the connecting rod 26 fixedly connected to the outer side of the force-bearing disk 25 will move inward with the sliding blocking plate 28 connected to the other end thereof. At this time, the pressure relief pipe 271 originally blocked by the sliding blocking plate 28 will open, and then it will be divided into two parts, one part will pass through the force-bearing disk 25 and enter the built-in tube 40, and the other part will enter the pressure relief pipe 271. At this time, the oil-water emulsion inside the pressure relief pipe 271 will hit the blocking plate 275, and then the connecting rod 26 fixedly connected to the outer side of the force-bearing disk 25 will move inward. The telescopic rod 274 connected to the outer side of the blocking plate 275 will be stretched, causing the blocking plate 275 to move away from the perforated plate 272, and then the oil-water emulsion will pass through the perforated plate 272 into the built-in tube 40, and then the oil-water emulsion in the built-in tube 40 will flow downward and squeeze the inclined pressure plate 32, and then the inclined pressure plate 32 will move downward with the inserted plate 35, and then the circular holes 36 opened on the surface of the inserted plate 35 will coincide with the transition pipe 37 and the extension pipe 39 respectively, and then the extension pipe 39 connected to the external heating equipment will have hot air flowing into it, and then the hot air will pass through the circular holes 36 and the transition pipe 37 in turn, and sprinkle on the drainage plate 38, and then the oil-water emulsion will be heated.

[0043] The above-mentioned embodiments are only preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work all fall within the scope of protection of the present invention.
