Description

Technical Field

[0001] The utility model belongs to the technical field of separation devices, and more particularly, to an oil-water separation device for gas stations. Background Art

[0002] During the operation process of oil product cleaning and filtering equipment in gas stations, water and impurities deposited or suspended at the bottom of oil tanks are separated through cyclic filtration to produce clean oil products and a small amount of wastewater. The wastewater contains a small amount of oil. To avoid environmental pollution, it needs to be treated and meet the detection standards before being discharged. Currently, the common practice in gas stations is to store it centrally in the hazardous waste temporary storage area and regularly transport it back to the oil depot for centralized treatment by oil tank trucks.

[0003] In the prior art, after retrieval, Chinese Patent No. CN202121684767.2 discloses a filtering device for treating oil-containing wastewater in gas stations, belonging to the field of filtering devices, including: a filtering tank; a filtering mechanism disposed inside the filtering tank for filtering, which includes a perforated support disc, a filter cloth, and a filling layer. There are multiple perforated support discs and filter cloths, and the multiple perforated support discs are arranged in the filtering tank from top to bottom.

[0004] Since the storage duration of the oil-containing wastewater is uncertain during storage, it may cause the oil in the oil-water mixture to adhere to the inner wall of the storage container, resulting in incomplete separation and discharge of oil and water when separating the oil and water. In the above solution, by arranging multiple layers of support discs and filter cloths inside the filtering device, the oil floats and separates. However, in the actual separation process, it may cause the oil to continuously adsorb on the filter cloth and the inner wall surface of the container, resulting in a reduction in the separation and discharge efficiency of the oil, and further reducing the efficiency of subsequent wastewater purification and discharge.

[0005] Regarding the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the utility model.

[0030] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the utility model.

[0031] Please refer to Figure 2 、 Figure 3 As shown in the figure, the present utility model is an oil-water separation device for a gas station, including a separation device 1. A sealing disc 2 is fixedly installed at the top of the separation device 1. An input pipe 3 is fixedly installed at the top of the sealing disc 2. A driving mechanism 4 is fixedly installed at the top of the sealing disc 2. A separation plate 5 is fixedly installed on the outer surface of the driving mechanism 4. The output end of the driving mechanism 4 is threadedly connected to a filter wire mesh 6. Clamping seats 7 are clamped on both sides of the filter wire mesh 6. The clamping seats 7 are slidably connected to the inner wall of the separation device 1. A water separation disc 8 is fixedly installed at the bottom inside the separation device 1. The bottom of the separation device 1 is fixedly connected to a diversion pipe 9. One end of the diversion pipe 9 is fixedly installed with a pumping device 10. An oil drain pipe 11 is arranged on one side of the sealing disc 2.

[0032] When oil and water need to be separated, the oily wastewater is input into the interior of the separation device 1 through the input pipe 3. Due to the different seals of oil and water, when a large amount of oily wastewater enters the interior of the separation device 1, the oil in the water will float on the upper layer of the wastewater. At this time, the filter disk 6 is located at the bottom inside the separation device 1. By starting the driving mechanism 4, the filter disk 6 is driven to displace inside the separation device 1, driving the clamping seats 7 on both sides to displace upward along the inner side of the separation device 1. Since the filter disk 6 has lipophilicity and filter holes on its surface, when the filter disk 6 gradually rises, the water at the upper layer height passes through the filter disk 6 and is filtered out to the lower part, and the oil on the upper layer follows the rise of the filter disk 6 and is pushed upward. At the same time, the separation plate 5 is driven by the driving mechanism 4 to rotate synchronously. When the filter disk 6 rises to the interface inside the sealing disk 2 and contacts the separation plate 5, the separation plate 5 continuously rotates and scrapes the oil adhering to the filter disk 6 to generate centrifugal force, quickly flowing to the inside of the drain pipe 11 at the same horizontal position for discharge, and the wastewater at the bottom is pumped out of the separation device 1 through the diversion pipe 9 and the pumping device 10.

[0033] In the present utility model, the driving mechanism 4 is fixed on the top of the sealing disk 2 and its output end penetrates into the interior of the separation device 1. After the oily wastewater enters the interior of the separation device 1, the driving mechanism 4 drives the filter disk 6 to cooperate with the clamping seat 7 to displace inside the separation device 1, so that the filter disk 6 continuously blocks and pushes the oil upward to float at the bottom of the wastewater layer, and the synchronously rotating separation plate 5 can contact the filter disk 6 and rotate quickly to generate a driving force on the oil, enabling it to be discharged through the drain pipe 11, preventing the oil from adhering to the inner wall of the separation device 1 and the filter disk 6 for a long time and causing accumulation and blockage, affecting the oil discharge effect, and improving the oil-water separation efficiency of the filtering equipment in the gas station.

[0034] In one embodiment, for the above-mentioned separation device 1, the separation device 1 includes a separation tank 101, an accommodation cavity 102 is provided inside the separation tank 101, an inner chute 103 is provided on the inner wall of the accommodation cavity 102, and the clamping seat 7 is slidably connected inside the inner chute 103.

[0035] The oily wastewater is transported to the interior of the accommodation cavity 102 inside the separation tank 101 through the input pipe 3. The filter disk 6 is located inside the accommodation cavity 102, and its outer edge is close to the inner wall of the accommodation cavity 102, so that the oily wastewater passes through the upper surface of the filter disk 6 after entering the accommodation cavity 102, increasing the filtering effect on the wastewater.

[0036] In one embodiment, for the above-mentioned separation tank 101, a water collecting hopper 104 is fixedly installed at the bottom of the separation tank 101, the water dividing disk 8 is located at the top inside the water collecting hopper 104, and the top of the diversion pipe 9 is fixedly connected to the bottom of the water collecting hopper 104.

[0037] The water collecting hopper 104 is conical and located at the bottom of the separation tank 101. When the wastewater passes through the filter wire mesh 6, it flows downward concentratedly, impacts on the water distribution plate 8, and then flows downward along the notches on the surface into the water collecting hopper 104 and is discharged into the diversion pipe 9.

[0038] By fixing the water distribution plate 8 inside the water collecting hopper 104, the filtered wastewater impacts on the water distribution plate 8 and then flows into the water collecting hopper 104, which can play a role in initially dispersing the impurities contained inside, so as to facilitate subsequent purification operations.

[0039] In one embodiment, for the above-mentioned driving mechanism 4, the driving mechanism 4 includes a driving motor 401, the output end of the driving motor 401 is fixedly installed with an output shaft 402, the separation plate 5 is fixedly connected to the outer surface of the output shaft 402, the output end of the output shaft 402 is fixedly installed with a rotating screw 403, and the filter wire mesh 6 penetrates and is threadedly connected to the outer surface of the rotating screw 403.

[0040] By starting the driving motor 401, the output shaft 402 can be driven to rotate and drive the separation plate 5 to rotate at the same time. At this time, the rotating screw 403 at the bottom drives the filter wire mesh 6 to drive the clamping seats 7 on both sides to slide on the inner wall of the inner chute 103, so that the filter wire mesh 6 rises upward at the bottom inside the separation tank 101, adsorbs and pushes the oil upward, and filters and blocks the wastewater below.

[0041] By fixing the driving motor 401 on the top of the sealing plate 2 and extending its output shaft 402 into the separation tank 101, the driving motor 401 can simultaneously provide driving force for both the separation plate 5 and the filter wire mesh 6, so that the oil can be quickly separated and discharged after being blocked, improving the oil-water separation efficiency and reducing the adhesion of oil.

[0042] In one embodiment, for the above-mentioned pumping device 10, the pumping device 10 includes a water pump 1011, a delivery pipe 1012 is arranged on the top of the water pump 1011, and a water purification device 12 is arranged at one end of the delivery pipe 1012.

[0043] The output end of the diversion pipe 9 is connected to the water pump 1011. When the wastewater flows into the water collecting hopper 104, the water pump 1011 is started to cooperate with the diversion pipe 9 to convey the wastewater into the delivery pipe 1012 and then to the inside of the water purification device 12 through the delivery pipe 1012.

[0044] By the cooperation of the diversion pipe 9 and the water pump 1011, the wastewater preliminarily filtered in the separation tank 101 can be quickly pumped into the water purification device 12, so as to facilitate the rapid centralized purification treatment of the wastewater.

[0045] In one embodiment, for the above-mentioned water purification device 12, the water purification device 12 includes a storage tank 1201. The top of the storage tank 1201 is threadedly connected with a top cover 1202. A stirring device 13 is arranged on the top of the top cover 1202. The bottom of the storage tank 1201 is fixedly connected with a water guide pipe 1203.

[0046] The delivery pipe 1012 is connected to one side of the storage tank 1201. After the wastewater is pumped into the storage tank 1201 by the water pump 1011 in cooperation with the delivery pipe 1012, the stirring device 13 on the top of the top cover can stir the inside of the storage tank 1201, increasing the interaction between the wastewater and the purification agent and improving the mixing and purification efficiency.

[0047] In one embodiment, for the above-mentioned stirring device 13, the stirring device 13 includes a stirring motor 1301. The output end of the stirring motor 1301 is fixedly installed with a stirring shaft 1302. The outer surface of the stirring shaft 1302 is fixedly installed with a stirring frame 1304.

[0048] By starting the stirring motor 1301, the stirring shaft 1302 can be driven to drive the stirring frame 1304 to rotate inside the storage tank 1201. By the rotation of the stirring frame 1304, the fluidity of the wastewater and the interaction frequency with the mixed agent are increased, so that the wastewater can be quickly mixed with the purification agent, increasing the decomposition rate of impurities in the wastewater, and further improving the wastewater purification efficiency.

[0049] In one embodiment, for the above-mentioned stirring frame 1304, the number of the stirring frames 1304 is several. One end of each of the several stirring frames 1304 is fixedly installed with an arc-shaped scraper 1305.

[0050] There are multiple groups of stirring frames 1304 arranged in a staggered manner outside the stirring frame 1304. When the stirring frame 1304 rotates, the arc-shaped scraper 1305 at its end is driven to rotate synchronously inside the storage tank 1201 and contact with its inner wall to generate friction, thereby scraping the impurities adhering to the inner wall to prevent them from adhering to the inner wall of the storage tank 1201 for a long time and affecting the wastewater separation, purification and discharge effect.

[0051] Through the above technical solutions: 1. By fixing the driving mechanism 4 on the top of the sealing disc 2 and making its output end penetrate into the inside of the separation device 1, when the oily wastewater enters the inside of the separation device 1, the driving mechanism 4 drives the filter wire mesh disc 6 to cooperate with the clamping seat 7 to displace inside the separation device 1, so that the filter wire mesh disc 6 continuously blocks and pushes the oil substances upward at the bottom of the wastewater layer, and the synchronously rotating separation plate 5 can contact the filter wire mesh disc 6 and rotate quickly to generate a driving force on the oil substances to discharge them through the oil discharge pipe 11, preventing the oil substances from adhering to the inner wall of the separation device 1 and the filter wire mesh disc 6 for a long time and causing accumulation and blockage, which affects the oil discharge effect and improves the oil-water separation efficiency of the filtering equipment in the gas station; 2. By fixing the driving motor 401 on the top of the sealing disc 2 and extending its output shaft 402 into the inside of the separation tank 101, the driving motor 401 can simultaneously provide driving forces for both the separation plate 5 and the filter wire mesh disc 6, so that the oil substances can be quickly separated and discharged after being blocked, improving the oil-water separation efficiency and reducing the adhesion of the oil substances.
