Description

Technical Field

[0001] This utility model relates to the field of oil removal device technology, and in particular to an alkaline oil removal device. Background Technology

[0002] In the manufacturing processes of heavy industries such as petrochemicals and coal chemicals, waste alkaline solutions rich in grease and complex organic matter are often generated. If these wastes are discharged directly into the natural environment without proper treatment, they will cause serious environmental pollution problems and pose a long-term threat to water bodies, soil, and ecosystems. Alkali degreasing devices are environmentally friendly equipment specifically designed to treat such industrial wastes. They are widely used in steel manufacturing, metal product processing, and other industries that require surface cleaning treatment. Through their efficient cleaning capabilities, they provide strong support for the surface treatment process of metal products, promoting the sustainable development of industrial production and the harmonious coexistence of environmental protection.

[0003] Most existing alkaline oil removal devices pour the oil-water mixture into a container and use gravity to separate the mixture into layers, forming a solid particle layer at the bottom. With continuous injection, the mixed solution overflows from the container through two outlets under the action of the baffles inside the container, thus achieving oil removal through gravity separation. However, since the density difference between oil and water is small, this results in a relatively long separation time.

[0004] Therefore, those skilled in the art have provided an alkaline oil removal device to solve the problems mentioned in the background art. Summary of the Invention

At the same time, the mounting frame can be quickly removed through the handle, which is convenient for cleaning and inspection and reduces downtime.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An alkaline oil removal device includes a mounting plate and a filter box.

[0008] The filter box has multiple mounting frames that slide inside, and each mounting frame has a filter screen fixedly installed inside. The filter box has multiple sealing rings fixedly installed at the top. Each mounting frame has a compression spring fixedly installed at the top. Each compression spring has a fixing block fixedly installed at the top. Each fixing block has a connecting block rotatably installed on both sides. Each connecting block has a locking block rotatably installed on opposite sides. Each fixing block has a handle fixedly installed at the top.

[0009] Furthermore, both of the sliding grooves are formed inside the mounting plate, and the multiple sliders are slidably disposed inside the two sliding grooves with opposite ends in pairs, and the multiple sliders are rotatably disposed at the upper and lower ends of the multiple rotating wheels with opposite ends in pairs.

[0010] Furthermore, the multiple rotating wheels are slidably disposed inside the mounting plate, and the multiple rotating blocks are rotatably disposed on opposite sides of the high-speed centrifuge at the lower end of the exterior. The multiple rotating blocks are rotatably disposed on opposite sides of the multiple rotating wheels on opposite sides of the centrifuge.

[0011] Furthermore, the two ends of the plurality of second springs are respectively fixedly disposed on opposite sides of the plurality of rotating blocks, and the two ends of the plurality of first springs are respectively fixedly disposed on opposite sides of the plurality of rotating blocks.

[0012] Furthermore, a second conveying pipe is fixedly installed on one side of the filter box, a floating suction port is fixedly installed at the input end of the second conveying pipe, a circulation tank is fixedly installed on the side of the second conveying pipe near the floating suction port, the floating suction port is externally located inside the circulation tank, and the output end of the first conveying pipe is fixedly located inside the circulation tank.

[0014] Furthermore, four support legs are fixedly installed at the lower end of the mounting plate, and a centrifugal pump is fixedly installed at the upper end of the mounting plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes an alkaline oil removal device. During the alkaline oil removal process, the alkaline solution, after preliminary filtration, is pushed into a high-speed centrifuge for deep oil removal. When the oil-water mixture is introduced into the rotating chamber of the high-speed centrifuge, as the chamber rotates at high speed, the two liquids with different densities, oil and water, begin to separate due to centrifugal force. Driven by centrifugal force, the lower-density oil molecules, due to the smaller centrifugal force, tend to move radially away from the axis of rotation, that is, move and accumulate towards the outside of the chamber. Meanwhile, the higher-density water molecules, under the greater centrifugal force, are pushed towards the closer side of the axis of rotation, that is, the inside of the chamber. This process utilizes the natural density difference between oil and water, as well as the separation effect of high-speed centrifugal force on substances of different densities, enabling efficient separation of the oil-water mixture in a short time. With the continuous action of centrifugal force, the oil layer and water layer gradually separate clearly, forming a distinct stratification phenomenon, thus completing the rapid separation of the oil-water mixture. At this time, the rotating block connected to the high-speed centrifuge... The rotation generated by the vibration causes the rotating wheel to roll inside the mounting plate. During the rolling process, the rotating wheel makes close contact with the mounting plate and generates a large frictional force, which consumes the vibration energy. At the same time, the slider slides in the groove, which not only increases the sliding friction but also further absorbs the vibration energy, achieving a shock absorption effect. In addition, as the rotating block rotates, it compresses the first spring and stretches the second spring. When the vibration weakens, the first and second springs help the rotating block quickly return to its initial state. When the oil-water mixture is placed in the rotating container of the high-speed centrifuge, as the container rotates rapidly, oil and water of different densities begin to separate due to the centrifugal force of different intensities. Since the density of oil is usually less than that of water, under the action of centrifugal force, oil molecules tend to move towards the outside of the rotation center, while water molecules tend to gather towards the inside of the rotation center. This natural stratification phenomenon based on density difference and centrifugal force achieves efficient and rapid separation of oil-water mixtures.

[0017] 2. The alkaline oil removal device proposed in this utility model allows for the replacement and cleaning of the filter screen by lifting the handle. This causes the fixing block at the lower end of the handle to rise inside the mounting frame. As the fixing block rises, the compression spring is stretched and deformed. Simultaneously, the connecting block rotates, causing the locking block to move inward. This gradually disengages the locking block from the filter box, releasing it from its locked state. At this point, the mounting frame can be quickly removed from the filter box for cleaning and replacement, reducing operational difficulty, improving replacement efficiency, and reducing maintenance time.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 One embodiment provided by this utility model:

[0028] An alkaline oil removal device includes a mounting plate 5 and a filter box 8. The mounting plate 5 has a shock-absorbing mechanism 2 inside, which includes multiple rotating blocks 201, multiple first springs 202, multiple rotating wheels 203, multiple sliders 204, two sliding grooves 205, and multiple second springs 206. A high-speed centrifuge 3 is installed inside the mounting plate 5. A first conveying pipe 11 is fixedly installed on one side of the upper end of the high-speed centrifuge 3. The two sliding grooves 205 are both opened inside the mounting plate 5. The multiple sliders 204 are slidably disposed inside the two sliding grooves 205 with opposite ends in pairs. The mounting plate 5 has multiple rotating wheels 203 at both ends, and two sliding grooves 205 are opened inside the mounting plate 5. Multiple sliders 204 are slidably disposed inside the two sliding grooves 205 with opposite ends in each pair. Multiple sliders 204 are rotatably disposed at the upper and lower ends of multiple rotating wheels 203 with opposite ends in each pair. Multiple second springs 206 are fixedly disposed at both ends on opposite sides of multiple rotating blocks 201. Multiple first springs 202 are fixedly disposed at both ends on opposite sides of multiple rotating blocks 201. Four support legs 6 are fixedly disposed at the lower end of the mounting plate 5. A centrifugal pump 4 is fixedly disposed at the upper end of the mounting plate 5.

[0029] Specifically, during operation, the oil-containing alkaline solution is pumped into the high-speed centrifuge 3 by centrifugal pump 4. When the oil-water mixture is sent into the rotating chamber of the high-speed centrifuge 3, the liquid mixture begins to be subjected to strong centrifugal force. Due to the different densities of oil and water, the two liquids exhibit different motion trends in the high-speed rotating environment. The oil, with its lower density, experiences relatively less centrifugal force and moves towards the far end of the rotating axis, that is, the outside of the chamber, where it accumulates to form an oil layer. At the same time, the water molecules, with their higher density, are pushed towards the near side of the rotating axis, that is, the inside of the chamber, under the drive of a larger centrifugal force, forming a water layer. The core of this separation process lies in... By utilizing the natural density difference between oil and water and the different effects of centrifugal force generated by high-speed rotation on substances of different densities, oil and water in an oil-water mixture can be effectively separated in a short time. As the high-speed centrifuge 3 continues to operate, the interface between the oil layer and the water layer gradually becomes clear, eventually forming a distinct stratification phenomenon. This not only improves separation efficiency but also ensures that the processed oil and water can be recycled and further processed separately, thereby achieving resource reuse and environmental protection. The principle of the high-speed centrifuge 3 is that, with the original horizontal direction as the axis and the original gravity as the radial direction, the centrifugal force generated by rotation will greatly exceed the original gravitational acceleration. This centrifugal force causes rapid oil-water separation. Due to the centrifugal force, vibrations are generated, which are transmitted to the rotating block 201 connected to the outside of the high-speed centrifuge 3. The rotating block 201 rotates due to the vibrations, stretching the second spring 206 and applying pressure to the first spring 202. As the rotating block 201 rotates, it synchronously drives the connected rotating wheel 203 to roll inside the mounting plate 5. Since both the rotating wheel 203 and the slider 204 are made of rubber, the rubber material increases the friction between the rotating wheel 203 and the mounting plate 5 during the rolling of the rotating wheel 203 and the sliding of the slider 204 within the groove 205, thus effectively... The vibration energy is absorbed by the ground. At the same time, the first spring 202 and the second spring 206, as elastic elements, play a role in resetting during the vibration process. That is, when the vibration causes the rotating block 201 to deviate from the initial position, the elastic force of the spring helps it return to its original position. Thus, the vibration generated by the high-speed centrifuge 3 during operation can be effectively reduced through the shock absorption mechanism 2, thereby protecting the equipment, reducing noise, and extending the service life of the equipment. At the same time, the stability of the equipment is improved, ensuring the smooth operation of the production process. When the oil-water separation is completed, the oil will enter the circulation tank 1 through the first conveying pipe 11, and the water will be transported and stored. The support leg 6 at the lower end of the mounting plate 5 plays a stabilizing role.

[0030] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6The filter box 8 has multiple sliding mounting frames 7 inside, each with a filter screen 13 fixedly mounted inside. Multiple sealing rings 18 are fixedly mounted on the upper part of each mounting frame 7. Compression springs 16 are fixedly mounted near the upper part of each mounting frame 7, and fixing blocks 15 are fixedly mounted on the upper ends of each compression spring 16. Connecting blocks 17 are rotatably mounted on both sides of each fixing block 15, and locking blocks 9 are rotatably mounted on opposite sides of each connecting block 17. Handles 14 are fixedly mounted on the upper ends of each fixing block 15. A second conveying pipe 12 is fixedly installed on one side of the filter box 8. A floating suction port 10 is fixedly installed at the input end of the second conveying pipe 12. A circulation tank 1 is fixedly installed on the side of the second conveying pipe 12 near the floating suction port 10. The floating suction port 10 is located outside the circulation tank 1. The output end of the first conveying pipe 11 is fixedly installed inside the circulation tank 1. Multiple fixed blocks 15 are slidably installed inside multiple mounting frames 7. Multiple locking blocks 9 are slidably installed inside the mounting frames 7 on the upper side. Multiple locking blocks 9 are slidably installed inside the filter box 8 on opposite sides.

[0031] Specifically, the filter box 8 performs preliminary filtration of impurities in the circulating liquid to ensure the cleanliness of the circulation process. The alkaline solution flows from the high-speed centrifuge 3 to the circulation tank 1 through the first delivery pipe 11, and then is drawn into the filter box 8 through the floating suction port 10 on the second delivery pipe 12. The second delivery pipe 12 is made of a softer material, and the floating suction port 10 automatically adjusts its position according to the liquid level to ensure that the drawn liquid contains minimal impurities. When the alkaline solution enters the filter box 8, it passes through the filter screen 13 inside the mounting frame 7. The filter screen 13 intercepts larger particles and other impurities. When it is necessary to replace or clean the filter screen 13, it is done by lifting the handle 14. This causes the fixing block 15 at the lower end of the handle 14 to rise inside the mounting frame 7, thereby pulling the compression spring 16 connected to the fixing block 15 to extend and deform. When the fixing block 15 rises, it will drive the connecting block 17 to rotate, which in turn drives the locking block 9 connected to it to move towards each other, so that the locking block 9 gradually disengages from the inside of the filter box 8, thereby releasing the locking state between the locking block 9 and the filter box 8. At this time, the mounting frame 7 and the filter screen 13 can be quickly removed from the filter box 8, and the mounting frame 7 releases the pressure on the sealing ring 18. The whole process not only simplifies daily maintenance work, but also improves the reliability of filtration.

[0032] Working principle: In the alkaline degreasing process, the floating suction port 10 feeds the alkaline solution into the second conveying pipe 12, allowing it to enter the filter box 8. It undergoes preliminary filtration through multiple filter screens 13, which effectively intercept larger particles and other impurities. The solution then enters the high-speed centrifuge 3 via the centrifugal pump 4 for further degreasing. During operation, the high-speed centrifuge 3 inevitably generates strong vibrations. These vibrations cause the connected rotating block 201 to rotate, which in turn causes the connected rotating wheel 203 to roll inside the mounting plate 5. During this rolling process, the rotating wheel 203 generates significant friction with the mounting plate 5, thus helping to remove impurities. Vibration energy is reduced and vibration transmission is minimized. Meanwhile, the slider 204 connected to the rotating wheel 203 will slide in the groove 205. The slider 204 is also made of rubber, which increases the friction during the sliding process and further absorbs vibration energy, thereby achieving the shock absorption function. When the rotating block 201 rotates, it will compress the first spring 202 and stretch the second spring 206. When the vibration weakens, the first spring 202 and the second spring 206 will drive the rotating block 201 to reset, so that the rotating block 201 returns to the initial state, thereby reducing the vibration generated by the high-speed centrifuge 3 during operation and improving the stability of operation. When the oil removal is completed, the oil will be transported to the inside of the circulation tank 1 through the first conveying pipe 11.

[0033] Secondly, when the filter screen 13 needs to be replaced and cleaned, simply lift the handle 14 to move the fixing block 15 upward inside the mounting frame 7. The rise of the fixing block 15 will stretch the compression spring 16, causing it to deform. At the same time, the connecting block 17 connected to the fixing block 15 will rotate, driving the locking block 9 to move in opposite directions, thereby gradually disengaging it from the filter box 8. Once the locking block 9 is completely disengaged, the mounting frame 7 can be easily removed from the filter box 8, achieving quick cleaning and replacement, reducing downtime, and lowering maintenance costs.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
