Description

Technical Field

[0001] This utility model relates to the field of oil-water separation technology, and in particular to a continuous oil-water separation device. Background Technology

[0002] Currently, in the fields of chemical, petroleum, metal smelting, or machining technology, a large amount of oily wastewater is often generated. This type of wastewater needs to be treated to remove oil before it can be discharged. When oily wastewater is introduced into the oil-water separation device on the market, the oily wastewater impacts the inside of the device, causing the oil foam on the surface of the wastewater to mix with the wastewater, resulting in a decrease in separation efficiency, an increase in the number of separations, and difficulty in cleaning up the separated oil foam.

[0003] In the prior art, patent (CN209583799U) proposes a fine continuous oil-water separation device, including a first separation tank, a buffer mechanism, a first separation mechanism, and a second separation mechanism. The buffer mechanism is provided at the upper end of the first separation tank, and the first separation mechanism is installed inside the first separation tank. The second separation mechanism is connected to one side of the first separation tank. An oil inlet is provided inside the upper inner wall of the first separation tank. When oily wastewater is introduced into the first separation tank, multiple rollers are arranged at the upper end of the first separation tank, and the upper and lower rollers are staggered with each other, which can block the oily wastewater to a certain extent and buffer the speed of the oily wastewater, reducing the speed of the oily wastewater entering the separation screen. This effectively solves the problem that in the past, oily wastewater would collide with the inside of the device, causing the oil foam on the surface of the wastewater to mix with the wastewater, resulting in a decrease in separation efficiency and an increase in the number of separations.

[0004] However, in the aforementioned existing technologies, after long-term separation of oil-water mixtures, oil stains are prone to clogging, affecting the separation effect and resulting in high replacement costs. Utility Model Content

[0005] The purpose of this invention is to provide a continuous water-oil separation device that solves the problems in the prior art where oil stains easily clog the oil-water mixture after long-term separation, affecting the separation effect and resulting in high replacement costs.

[0006] To achieve the above objectives, this utility model provides a continuous water-oil separation device, including a separation tank and a separation mechanism. The separation mechanism includes an internal base, a first separation plate, a second separation plate, a disassembly assembly, a feeding assembly, and a discharge assembly.

The first separation plate and the second separation plate are both fixedly connected to the internal base and located on the upper and lower sides of the internal base, respectively. The internal base is fixedly connected to the separation tank and located on the inner wall of the separation tank.

[0007] The disassembly assembly includes a drawer, multiple oil-water separation membranes, and two limiting plates. Both limiting plates are fixedly connected to the drawer and located on the outside of the drawer. Each oil-water separation membrane is detachably connected to the drawer and located on the inside of the drawer. The drawer is detachably connected to the inner seat and located on the inside of the inner seat.

[0008] The feeding assembly includes a feeding pipe and a cleaning cylinder. The cleaning cylinder is detachably connected to the feeding pipe and is located inside the feeding pipe. The feeding pipe is fixedly connected to the separation box and is located above the separation box.

[0009] The discharge assembly includes two guide blocks and a drain pipe. The drain pipe is fixedly connected to the separation box and located below the separation box. Both guide blocks are fixedly connected to the separation box and located at the inner bottom of the separation box.

[0010] The separation box includes a box body, an adding pipe, multiple support columns, and an oil drain pipe. The oil drain pipe is fixedly connected to the box body and located on the front side of the box body. Each support column is fixedly connected to the box body and located below the box body. The adding pipe is fixedly connected to the box body and located above the box body.

[0011] This utility model discloses a continuous oil-water separation device. The disassembly assembly contains a plurality of oil-water separation membranes within a suction seat, enabling multi-layered and multi-level separation of oil and water mixtures. The separated oil is discharged in one go, achieving continuous oil-water separation.

[0020] This utility model provides a continuous water-oil separation device, including a separation box 101 and a separation mechanism 102. The separation mechanism 102 includes an internal base 103, a first separation plate 104, a second separation plate 105, a disassembly assembly 106, a feeding assembly 107, and a discharge assembly 108. The disassembly assembly 106 includes a drawer 109, multiple oil-water separation membranes 110, and two limiting plates 111. The feeding assembly 107 includes a feeding pipe 112 and a cleaning cylinder 113. The discharge assembly 108 includes two guide blocks 114 and a drain pipe 115. The separation box 101 includes a box body 116, an adding pipe 117, multiple support columns 118, and an oil drain pipe 119.

[0021] In this specific embodiment, the discharge assembly 108 is fixedly connected to the separation box 101, the feeding assembly 107 is fixedly connected to the separation box 101, the disassembly assembly 106 is detachably connected to the built-in seat 103, the first separation plate 104 and the second separation plate 105 are both fixedly connected to the built-in seat 103, the built-in seat 103 is fixedly connected to the separation box 101, both limiting plates 111 are fixedly connected to the drawer seat 109, each oil-water separation membrane 110 is detachably connected to the drawer seat 109, the drawer seat 109 is detachably connected to the built-in seat 103, the impurity removal cylinder 113 is detachably connected to the feeding pipe 112, the feeding pipe 112 is fixedly connected to the separation box 101, the drain pipe 115 is fixedly connected to the separation box 101, and both guide blocks 114 are connected to the separation box 101. The oil drain pipe 119 is fixedly connected to the housing 116, each of the foot posts 118 is fixedly connected to the housing 116, and the adding pipe 117 is fixedly connected to the housing 116. Multiple oil-water separation membranes 110 are installed in the drawer 109 within the disassembly assembly 106, enabling multi-level and multi-stage separation of oil and water mixtures and discharging the separated oil at once. This allows for continuous oil-water separation. The drawer 109 can also be manually detached from the internal seat 103, facilitating cleaning or replacement of the oil-water separation membranes 110 and ensuring effective filtration and stratification of the oil over long-term use. This design is convenient, simple in structure, and easy to use. While maintaining continuous oil-water separation, it solves the problem of oil clogging after long-term separation of oil-water mixtures, which affects the separation effect and results in high replacement costs.

[0022] The discharge assembly 108 is located below the separation box 101, the feeding assembly 107 is located above the separation box 101, the disassembly assembly 106 is located inside the built-in seat 103, the first separation plate 104 and the second separation plate 105 are located on the upper and lower sides of the built-in seat 103 respectively, the built-in seat 103 is located on the inner wall of the separation box 101, and the built-in seat 103 is fixed to the inner wall of the box body 116. The separation effect of the first separation plate 104 is lower than that of the second separation plate 105. During the process from the first separation plate 104 to the second separation plate 105, the oil-water mixture is gradually separated in multiple layers to ensure that the water at the bottom of the box body 116 does not contain oil.

[0023] Secondly, both limiting plates 111 are located outside the drawer seat 109, and each oil-water separation membrane 110 is located inside the drawer seat 109. The drawer seat 109 is located inside the built-in seat 103, the impurity removal cylinder 113 is located inside the feeding pipe 112, the feeding pipe 112 is located above the separation box 101, and an electronic valve is installed inside the drain pipe 115 to control the discharge of water separated from the bottom of the box 116. The setting of the limiting plate 111 facilitates the insertion and limiting of the drawer seat 109. When the two limiting plates 111 abut against the back side wall of the box 116, it means that the drawer seat 109 is completely placed inside the inner seat 103, and normal water-oil separation can be performed. The oil drain pipe 119 is not a single pipe, but an oil collection unit composed of a collection plate and a pipe. The width of the collection plate is the same as that of the drawer seat 109, ensuring that all the oil discharged from the drawer seat 109 is collected.

[0024] Meanwhile, the drain pipe 115 is located below the separation box 101, the two guide blocks 114 are located at the bottom of the separation box 101, the oil drain pipe 119 is located on the side of the box body 116, each of the foot posts 118 is located below the box body 116, and the addition pipe 117 is located above the box body 116. It should be noted that each oil-water separation membrane 110 in the drawer seat 109 includes an oleophilic hydrophobic membrane and a hydrophilic oleophobic membrane. The multi-layer combination ensures that after the oil-water mixture passes through the second separation plate 105, only the water passes through. The oleophilic hydrophobic membrane and the hydrophilic oleophobic membrane overlap and combine with each other to effectively separate the oil. Under the tilting action of the built-in seat 103, the oil is discharged from the oil drain pipe 119.

[0025] In this embodiment, the separation effect of the first separating plate 104 is lower than that of the second separating plate 105. During the process from the first separating plate 104 to the second separating plate 105, the oil-water mixture undergoes gradual multi-layer separation, ensuring that the water at the bottom of the tank 116 is oil-free. An electronic valve is installed inside the drain pipe 115 to control the discharge of the water separated at the bottom of the tank 116. The two limiting plates 111 facilitate the insertion and limiting of the drawer seat 109. When the two limiting plates 111 abut against the back wall of the tank 116, it indicates that the drawer seat 109 is completely placed inside the inner seat 103. Normal oil-water separation can be performed. The oil drain pipe 119 is not a single pipe, but an oil collection unit consisting of a collection plate and a pipe. The width of the collection plate is the same as that of the extraction seat 109, ensuring that all the oil discharged from the extraction seat 109 is collected. It should be noted that each oil-water separation membrane 110 in the extraction seat 109 includes an oleophilic hydrophobic membrane and a hydrophilic oleophobic membrane. The multi-layer combination ensures that after the oil-water mixture passes through the second separation plate 105, only the water passes through. The oleophilic hydrophobic membrane and the hydrophilic oleophobic membrane overlap and combine with each other to effectively separate the oil. Under the tilting action of the built-in seat 103, the oil is discharged from the oil drain pipe 119.
