Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of oil-water separation devices, specifically, to an oil-water separation device. Background Technology

[0002] Industrial production, catering services, and daily life generate large amounts of oily wastewater. If this oily wastewater is discharged directly without effective treatment, it will severely damage the aquatic ecosystem, causing a series of problems such as eutrophication and the death of aquatic organisms. Therefore, oil-water separation devices are crucial equipment for treating oily wastewater, and their performance directly affects environmental protection effectiveness and resource utilization efficiency.

[0003] However, existing oil-water separation devices generally have some significant shortcomings, especially in cleaning up floating oil layers. Most traditional devices lack efficient and convenient methods for cleaning the oil layer after initial oil-water separation. In industrial sectors, such as metal processing and machinery manufacturing, the oily wastewater generated during production contains large amounts of mineral oil and metal fragments. After oil-water separation, the floating oil layer mixes with these impurities, and traditional devices struggle to completely remove this complex oil layer, resulting in incomplete cleaning and continued contamination of the treated water by residual oil.

[0004] In the catering industry, kitchen wastewater is rich in animal and vegetable oils. After passing through a separation device, the floating oil layer is highly viscous, and existing separation devices cannot flexibly and promptly remove this oil layer. This not only affects the continuous working efficiency of the separation device but may also cause equipment blockage and shorten its lifespan. Moreover, manually cleaning the floating oil layer is costly, requiring a large amount of manpower and periodic shutdowns for cleaning, thus disrupting normal production and operation activities.

[0005] With increasingly stringent environmental standards and growing public awareness of water resource protection, the development of an oil-water separation device capable of efficiently removing floating oil layers is urgently needed. This would not only improve oil-water separation efficiency and reduce environmental pollution risks, but also enable oil resource recycling and reuse, increasing resource utilization and meeting the needs of sustainable development. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide an oil-water separation device, which solves the technical problem in the prior art that the floating oil layer mixes with impurities, and traditional devices have difficulty in completely cleaning out these complex oil layers, resulting in incomplete oil layer cleaning and residual oil stains continuing to contaminate the treated water.

[0007] According to one aspect, at least one embodiment of the present disclosure provides an oil-water separation device, comprising:

[0008] A treatment tank and a pair of inlet and outlet pipes, the inlet and outlet pipes being disposed on both sides of the treatment tank;

[0009] A dosing assembly is disposed at the top of the treatment tank;

[0010] An aeration pipe is installed at the bottom of the treatment tank;

[0011] A separation and cleaning assembly is disposed on the processing pool;

[0012] The separation and cleaning component has a pair of connecting plates, both of which are located at the top ends of the treatment pool. A guide rod is provided between each pair of opposing connecting plates, and a drive screw is rotatably connected between the pair of connecting plates. A collection tank is provided on one side of the treatment pool, and a discharge pipe is provided outside the treatment pool, which is connected to the inside of the collection tank.

[0013] As a further technical solution, both ends of the guide rod are slidably fitted with movable plates, one end of the movable plate is connected to the drive screw through a threaded connection, and a shovel plate is provided at the bottom of the movable plate.

[0014] As a further technical solution, a drive motor is provided at the lower end of one end of the treatment pool, and a transmission wheel is provided at the output end of the drive motor and at one end of the drive screw. The transmission wheels are connected by belt drive.

[0015] As a further technical solution, a side groove is provided on one side of the treatment pool, and an air pipe is provided in the side groove. One end of the air pipe is located outside the treatment pool, and several air nozzles are provided on the air pipe, all of which are inclined downwards.

[0016] As a further technical solution, the dosing assembly includes a pair of fixing rods, which are fixed at both ends of the top of the treatment tank. A horizontal pipe is connected between the fixing rods, and a connecting pipe is provided at one end of the horizontal pipe. Several dispersion holes are opened on the bottom surface of the horizontal pipe.

[0017] As a further technical solution, the lower end face of the collection trough opening is matched with the height of the shovel plate, and the inner surface of the shovel plate is an inclined structural surface.

[0018] As a further technical solution, the fixing rod and the horizontal tube are located in the middle of the treatment pool.

[0019] As a further technical solution, the drive screw has a double-segment thread structure, and the thread directions at both ends of the drive screw are opposite.

[0020] As a further technical solution, the bottom surface of the collection tank is an arc-shaped inclined structure, and the bottom surface of the collection tank is inclined to the side of the discharge pipe.

[0021] The beneficial effects of the embodiments disclosed herein are as follows:

[0022] 1. The beneficial effects of the separation and cleaning component in this disclosure are that the drive motor drives the drive screw, enabling the moving plate and the shovel to efficiently clean the floating oil layer. The guide rod ensures the stable movement of the moving plate and ensures the shovel accurately scrapes the oil. The drive screw with a double-segment thread structure can simultaneously control the two moving plates to clean the oil layer in a concentrated manner. The air nozzle sprays air to assist in stirring the liquid, causing the oil layer to gather and helping the oil layer enter the collection tank. The height of the collection tank is matched with that of the shovel, and the inner bottom surface is inclined to facilitate the collection and discharge of the oil layer, which greatly improves the oil layer cleaning efficiency and reduces the pollution of the treated water by residual oil.

[0023] 2. In this disclosure, the dosing component has significant advantages. The fixed rod supports the horizontal pipe, the connecting pipe introduces the chemical solution, and the dispersion holes on the bottom of the horizontal pipe can evenly disperse the chemical solution, allowing the chemical solution to quickly mix with the oil and water. The dosing component, located in the middle of the treatment tank, allows the chemical solution to quickly spread to the surroundings, promoting the full solidification and floating of the oil and water. This creates favorable conditions for subsequent oil layer cleaning, improves the overall effect of oil-water separation, ensures the stable and efficient operation of the oil-water separation process, and reduces the difficulty of oil-water separation.

[0036] like Figures 1-4 As shown, an oil-water separation device according to an embodiment of the present disclosure is illustrated, comprising:

[0037] The treatment tank 1 and a pair of inlet and outlet pipes 2 are arranged on both sides of the treatment tank 1;

[0038] Dosing assembly 5, wherein the dosing assembly 5 is disposed at the top of the treatment tank 1;

[0039] Aeration pipe 3 is installed at the bottom of the treatment tank 1;

[0040] Separation and cleaning component 4 is disposed on the processing pool 1;

[0041] The separation and cleaning component 4 has a pair of connecting plates 4-1, each of which is located at both ends of the top of the treatment tank 1. A guide rod 4-2 is provided between each pair of opposing connecting plates 4-1. A drive screw 4-3 is rotatably connected between the pair of connecting plates 4-1. A collection trough 4-4 is provided on one side of the treatment tank 1. A discharge pipe 4-5 is provided outside the treatment tank 1, and the discharge pipe 4-5 communicates with the inside of the collection trough 4-4. Moving plates 4-6 are slidably fitted onto both ends of the guide rods 4-2, and one end of the moving plate 4-6 is connected to the drive screw. 4-3 is connected by a threaded connection. The bottom of the movable plate 4-6 is provided with a shovel plate 4-7. A drive motor 4-8 is provided at the lower end of one end of the treatment pool 1. The output end of the drive motor 4-8 and one end of the drive screw 4-3 are both provided with a transmission wheel 4-9. The transmission wheels 4-9 are connected by a belt drive. A side groove 4-10 is opened on one side of the treatment pool 1. An air pipe 4-11 is provided in the side groove 4-10. One end of the air pipe 4-11 is located outside the treatment pool 1. Several air nozzles 4-12 are provided on the air pipe 4-11. All air nozzles 4-12 are inclined downward.

[0042] In some examples, during the oil-water separation process, a separation and cleaning assembly 4 is designed to effectively clean the oil layer that floats after being mixed with chemicals. This assembly includes a pair of connecting plates 4-1 located at both ends of the top of the treatment tank 1, providing a mounting base for the guide rod 4-2 and the drive screw 4-3. The guide rod 4-2, positioned between the pair of opposing connecting plates 4-1, provides stable guidance for the movement of the moving plate 4-6, preventing the moving plate 4-6 from shifting during movement. The drive screw 4-3, rotatably connected between the connecting plates 4-1, is the core component that drives the moving plate 4-6 to move. The core component, a collection tank 4-4 on one side of the treatment tank 1, is connected to an external discharge pipe 4-5 for collecting and discharging the cleaned oil layer. A movable plate 4-6, slidably fitted at both ends of a guide rod 4-2, is threadedly connected at one end to a drive screw 4-3. When the drive screw 4-3 rotates, the movable plate 4-6 moves linearly along the guide rod 4-2. A scraper 4-7 at the bottom of the movable plate 4-6 scrapes up the oil layer floating on the surface of the treatment tank 1 during its movement and pushes the oil layer towards the collection tank 4-4, thus cleaning and treating the oil layer. A drive motor 4-8 is installed at the lower end of one end of the tank 1. Its output end is connected to a transmission wheel 4-9 at one end of the drive screw 4-3 via a belt drive. When the drive motor 4-8 starts, power is transmitted to the drive screw 4-3 through the belt, causing the drive screw 4-3 to rotate. In addition, an air pipe 4-11 is installed in a side groove 4-10 on one side of the treatment tank 1, with one end located outside the treatment tank 1. Several downward-sloping air nozzles 4-12 are installed on the air pipe 4-11, which can spray gas into the treatment tank 1. This gas can help agitate the liquid in the treatment tank 1, making the oil layer better. On the one hand, the oil layer accumulates on the ground. On the other hand, when the shovel plate 4-7 cleans the oil layer, the gas sprayed by the air nozzle 4-12 can help blow the oil layer towards the collection tank 4-4, improving the cleaning efficiency. Through the coordinated work of components such as the connecting plate 4-1, guide rod 4-2, drive screw 4-3, collection tank 4-4, discharge pipe 4-5, moving plate 4-6, shovel plate 4-7, drive motor 4-8, transmission wheel 4-9, belt, side groove 4-10, air pipe 4-11 and air nozzle 4-12, the separation and cleaning component 4 can efficiently scrape and clean the floating oil layer, completing the oil layer cleaning work in the oil-water separation process.

[0043] like Figures 1-4 As shown in the figure, the dosing assembly 5 in this embodiment includes a pair of fixing rods 5-1, which are fixed at both ends of the top of the treatment tank 1. A horizontal pipe 5-2 is connected between the fixing rods 5-1. A connecting pipe 5-3 is provided at one end of the horizontal pipe 5-2. Several dispersion holes 5-4 are opened on the bottom surface of the horizontal pipe 5-2.

[0044] In some examples, during the oil-water separation process, a dosing assembly 5 is designed to ensure effective oil-water separation. This assembly includes a pair of fixed rods 5-1 at both ends of the top of the treatment tank 1, providing stable support for the horizontal pipe 5-2. The horizontal pipe 5-2, connected between the fixed rods 5-1, is the main channel for chemical delivery. A connecting pipe 5-3 at one end of the horizontal pipe 5-2 is used to connect to an external chemical supply device, allowing the chemical to smoothly enter the horizontal pipe 5-2. Several dispersion holes 5-4 on the bottom surface of the horizontal pipe 5-2 can evenly disperse the chemical into the treatment tank 1. When it is necessary to add chemical to the treatment tank... When chemicals are added to tank 1, the chemicals enter the horizontal pipe 5-2 through the connecting pipe 5-3 and then flow out from the dispersion hole 5-4, spreading evenly on the liquid surface of treatment tank 1. These chemicals can mix with oil and water, causing the oil and water to solidify and float to the liquid surface, thereby achieving preliminary separation of oil and water. This creates conditions for the subsequent cleaning of the oil layer by the separation and cleaning component 4. Through the coordinated work of components such as the fixing rod 5-1, the horizontal pipe 5-2, the connecting pipe 5-3, and the dispersion hole 5-4, the chemical dosing component 5 can stably and evenly fill the treatment tank 1 with chemicals, causing the oil and water to solidify and float, laying the foundation for the oil-water separation process.

[0045] For example, such as Figure 1 As shown, the lower end face of the opening of the collection groove 4-4 is matched with the height of the shovel plate 4-7, and the inner surface of the shovel plate is an inclined structural surface.

[0046] In some examples, by matching the height, when the shovel plate 4-7 scoops up the oil layer, the oil layer rises in height and flows entirely into the collection tank 4-4, promoting the cleaning effect.

[0047] For example, such as Figure 1 As shown, the fixing rod 5-1 and the horizontal tube 5-2 are located in the middle of the treatment pool 1.

[0048] In some examples, by being located in the center, the solution can be directly added to the center of treatment tank 1, and can be quickly and evenly distributed to the surrounding area.

[0049] For example, such as Figure 1 As shown, the drive screw 4-3 has a double-segment thread structure, and the thread directions at both ends of the drive screw 4-3 are opposite.

[0050] In some examples, the two moving plates 4-6 can be driven to approach or move away synchronously through opposite threaded structures, ensuring a concentrated cleaning effect on the oil layer.

[0051] For example, such as Figure 1 As shown, the inner bottom surface of the collection tank 4-4 is an arc-shaped inclined structure surface, and the inner bottom surface of the collection tank 4-4 is inclined to the side of the discharge pipe 4-5.

[0052] In some examples, the curved inclined structure facilitates the concentrated flow of the collected oil layer towards the discharge pipe 4-5 for rapid discharge.

[0053] In actual use: oily wastewater is introduced into treatment tank 1 through inlet / outlet pipe 2. The connecting pipe 5-3 of the dosing component 5 is connected to the external chemical supply device. The chemical solution is evenly distributed in treatment tank 1 through the dispersion hole 5-4 of the horizontal pipe 5-2 to cause the oil and water to solidify and float. The aeration pipe 3 is started for aeration. Then the drive motor 4-8 is started. The drive motor 4-8 drives the drive screw 4-3 to rotate through the transmission wheel 4-9 and belt. The drive screw 4-3 drives the moving plate 4-6 to move along the guide rod 4-2. The shovel plate 4-7 at the bottom of the moving plate 4-6 scrapes up the floating oil layer and pushes it into the collection tank 4-4. At the same time, the air nozzle 4-12 of the air pipe 4-11 in the side tank 4-10 sprays air to assist in the collection of the oil layer. The oil layer in the collection tank 4-4 is discharged through the discharge pipe 4-5.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
