Description

Technical Field

[0001] The present application relates to the field of oil separation technology, and in particular to a high-efficiency oil separation device. Background Art

[0002] In industrial production activities, especially in the petroleum and petrochemical industries, a large amount of oil-containing slurry is often produced. The oil in the oil-containing slurry mainly exists in three states: floating oil, emulsified oil and dissolved oil. Among them, floating oil is relatively easy to separate from water by physical methods due to its large particles; emulsified oil and dissolved oil are difficult to separate from water due to their small oil droplet diameter or partial dissolution in water, causing serious environmental pollution after discharge.

[0003] At present, the main equipment for treating oil-containing slurry is oil separation equipment. Existing oil separation equipment usually uses the density difference between water and oil to separate and remove floating oil in oil-containing slurry through natural flotation under the action of gravity. During the removal process, the slurry liquid surface is easily disturbed, and the slurry liquid surface fluctuations cause the separated floating oil to have a high water content, which not only reduces the oil recovery efficiency, but also increases the difficulty and cost of subsequent treatment. Summary of the invention

[0004] In order to reduce the water content in oil when separating water from oil, thereby improving the oil recovery efficiency and reducing the difficulty and cost of subsequent processing, the present application provides a high-efficiency oil separation device.

[0005] The present application provides an efficient oil separation device adopting the following technical solution: A high-efficiency oil separation device, comprising a primary separation mechanism, a clear liquid separation mechanism and a turbid liquid separation mechanism; the primary separation mechanism comprises a raw water pipe, a primary separation pipe and a first motor, the raw water pipe is hollowed out, the inner wall of the raw water pipe is provided with a primary separation membrane, the membrane holes of the primary separation membrane can only allow water molecules to pass through; the primary separation pipe is sleeved outside the raw water pipe, the first motor is arranged at the end of the primary separation pipe, and the first motor is used to drive the raw water pipe to rotate; the raw water pipe and the primary separation pipe are both inclined and the height of the water outlet is lower than that of the water inlet. water end; the clear liquid separation mechanism includes a sedimentation tank, which is used to hold the first clear liquid flowing out of the primary branch pipe; the turbid liquid separation mechanism includes a filter screen and a clear liquid pool, the filter screen is used to hold the turbid liquid flowing out of the primary branch pipe, the mesh of the filter screen is only for water molecules to pass through, and the clear liquid pool is used to hold the second clear liquid flowing out of the filter screen; a conveying line is arranged between the clear liquid pool and the sedimentation tank, and the conveying line is used to convey the second clear liquid in the clear liquid pool to the sedimentation tank.

[0006] By adopting the above technical scheme, when separating water and oil, the oil-containing raw water is first introduced into the raw water pipe, and then the first motor is started. The first motor drives the raw water pipe to rotate at a high speed. During the rotation of the raw water pipe, the water molecules with higher density in the raw water pass through the primary separation membrane and the hollow raw water pipe under the action of centrifugal force and enter the gap between the primary separation pipe and the raw water pipe, forming a first clear liquid with a lower oil content, and a turbid liquid with a higher oil content remains in the raw water pipe, so as to perform preliminary separation of water and oil and remove part of the water in the raw water.

[0007] Since the raw water pipe and the primary branch pipe are both inclined, the first clear liquid in the primary branch pipe after the initial separation flows into the sedimentation tank under its own gravity, where it is precipitated and then subjected to subsequent treatment. The turbid liquid with a high oil content flowing out of the raw water pipe flows into the filter net under its own gravity, and the oil droplets with larger diameters remain on the filter net. The remaining oil flows through the mesh of the filter net with the water and flows into the clear liquid pool to form the second clear liquid; finally, the second clear liquid is transported from the clear liquid pool to the sedimentation tank for secondary treatment by a conveying line. Thus, the above structure is used to form multi-stage separation, and different treatment methods are adopted for water with different oil contents, thereby improving the oil recovery effect and efficiency, thereby reducing the subsequent treatment cost and difficulty.

[0008] Optionally, the raw water pipe is coaxially connected to a rotating shaft, a plurality of sets of fan blades are arranged on the circumference of the rotating shaft, ends of the fan blades away from the rotating shaft are connected to scraper plates, and edges of the scraper plates abut against the primary separation membrane.

[0009] By adopting the above technical scheme, when the raw water flows in the raw water pipe, the water pressure drives the fan blades to rotate, and the fan blades stir the raw water to reduce the possibility of oil in the raw water adhering to the primary separation membrane and clogging the primary separation membrane; and in the process of rotation of the fan blades, the scraper plate is synchronously driven to move relative to the primary separation membrane to scrape off the oil adhering to the primary separation membrane, further reducing the possibility of oil in the raw water adhering to the primary separation membrane and clogging the primary separation membrane.

[0010] Optionally, the clear liquid separation mechanism also includes a mounting frame and a rotating frame, the rotating frame is rotatably connected to the mounting frame; a plurality of sedimentation tanks are provided, and the plurality of sedimentation tanks are all installed on the rotating frame, and the plurality of sedimentation tanks are arranged at intervals around the axis of rotation of the rotating frame relative to the mounting frame, and the sedimentation tanks pass under the water outlet of the primary branch pipe during the rotation of the rotating frame; a plurality of hinged rods are provided on the surface of the sedimentation tank facing the rotating frame, and the plurality of hinged rods are all extended along the gravity direction of the sedimentation tank, and the plurality of hinged rods are arranged at intervals in the horizontal direction; one end of the hinged rod is hinged to the surface of the sedimentation tank facing the rotating frame, and the other end is hinged to the surface of the rotating frame facing the sedimentation tank.

[0011] By adopting the above technical scheme, the first clear liquid flowing out from the primary branch pipe flows into the sedimentation tank below the water outlet end thereof (for the convenience of expression, the sedimentation tank will be temporarily named the first sedimentation tank in the following text, and the next sedimentation tank after the sedimentation tank that will move below the water outlet end will be named the second sedimentation tank), forming an impact on the first sedimentation tank, and the first sedimentation tank receives the first clear liquid while driving the rotating frame to rotate. During the rotation process, the second sedimentation tank gradually moves to below the water outlet end of the primary branch pipe, and begins to receive the first clear liquid while driving the rotating frame to rotate. At this time, the first clear liquid no longer impacts the first sedimentation tank, so that a relatively stable sedimentation environment is formed in the first sedimentation tank, so that the clear liquid separation mechanism can have a stable sedimentation environment while continuously receiving the first clear liquid from the primary branch pipe, thereby ensuring the oil separation efficiency.

[0012] Optionally, a hollow support plate is provided in the sedimentation tank, and the support plate divides the sedimentation tank into an upper clear liquid chamber and a lower clear water chamber; multiple layers of filter membranes are placed on the support plate, and the membrane pores of the filter membranes can only allow water molecules to pass through.

[0013] By adopting the above technical solution, after the first clear liquid enters the sedimentation tank, it first enters the clear liquid cavity and precipitates in the clear liquid cavity. During the sedimentation process, the oil floats up, and at the same time, the water in the clear liquid cavity gradually flows into the clean water cavity through the filter membrane under the action of its own gravity to form clean water; after a certain period of time, most of the oil is filtered to the topmost filter membrane, and the topmost filter membrane is removed, and then the oil attached to the filter membrane is scraped off. Thus, further water-oil separation is completed while sedimentation is being carried out, and because the filter membrane is placed on the support plate, the topmost filter membrane can be easily removed, which is convenient for handling and also enables the sedimentation tank to be suitable for the sedimentation tank that can rotate with the rotating frame for a long time. After all the filter membranes on the support plate are used up, filter membranes can be added to the support plate, which is simple to operate and has a high degree of automation.

[0014] Optionally, the sedimentation tank is provided with a hose, and the mounting frame is provided with a clean water pipe; one end of the hose is connected to the clean water chamber, and the other end is connected to the clean water pipe; the clean water pipe is provided with a negative pressure pump, and the negative pressure pump is used to transport the clean water in the clean water chamber to the clean water pipe; the mounting frame is provided with a distillation box, and the sedimentation tank passes through the distillation chamber of the distillation box during the rotation of the rotating frame.

[0015] By adopting the above technical solution, the negative pressure pump transports the clean water in the clean water chamber to the clean water pipe, on the one hand, to empty the clean water chamber and collect the clean water; on the other hand, the weight of the sedimentation tank that has been filled with the first clean liquid is reduced to reduce the load on the hinged rod, and at the same time, the center of gravity of the rotating frame as a whole is deviated from the center position of the rotating frame, so that the rotating frame can rotate smoothly after being impacted by the first clean liquid.

[0016] In addition, after the sedimentation tank enters the distillation chamber, the distillation box heats and distills the sedimentation tank, thereby distilling the water in the sedimentation tank, further reducing the water content in the oil, and improving the oil recovery effect and efficiency.

[0017] Optionally, the mounting frame is movably connected with a suction cup, and the suction cup is used to grab the uppermost filter membrane in the sedimentation tank leaving the distillation chamber.

[0018] By adopting the above technical solution, after the sedimentation tank leaves the distillation chamber, the uppermost filter membrane in the sedimentation tank is removed by a suction cup to perform subsequent separation treatment on the oil on the filter membrane, and the sedimentation tank can also be used for the next process of receiving the first clear liquid.

[0019] Optionally, rigid gaskets are provided at the four corners of the filter membrane.

[0020] By adopting the above technical solution, on the one hand, a certain isolation is formed between adjacent filter membranes by using a gasket with a certain thickness, so that there is a certain gap between adjacent filter membranes. When the suction cup absorbs the uppermost filter membrane, the risk of the filter membrane below the filter membrane being taken away or driven away is reduced.

[0021] On the other hand, the gravity of the gasket is used to increase the gravity of the filter membrane and the rigidity at the four corners of the filter membrane, thereby reducing the possibility of displacement of the filter membrane under the impact of the first clear liquid.

[0022] In addition, a rigid gasket is also used to provide a relatively flat adsorption surface for the suction cup, so as to facilitate the suction cup to grasp the filter membrane stably.

[0023] Optionally, the gasket is magnetic.

[0024] By adopting the above technical solution, the connection between adjacent filter membranes is established by utilizing the attractive force between adjacent gaskets, thereby further reducing the risk of displacement of the filter membranes under the impact of the first clear liquid.

[0025] Optionally, the filter net is made of flexible material; the turbid liquid separation mechanism includes a plurality of first cylinders, the plurality of first cylinders are vertically arranged, the output ends of the plurality of first cylinders are connected to the filter net, and the plurality of connection points formed between the plurality of first cylinders and the filter net are arranged at intervals along the edge of the filter net.

[0026] By adopting the above technical solution, the turbid liquid with a high oil content leaving the water outlet of the raw water pipe flows to the filter screen. At this time, the first cylinder is started to make the end of the first cylinder move up and down asynchronously, thereby driving the filter screen to shake, so as to filter the turbid liquid more efficiently.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: By setting up a primary separation mechanism, a clear liquid separation mechanism and a turbid liquid separation mechanism, the primary separation mechanism is used to centrifuge the raw water to separate the raw water into a turbid liquid and a clear liquid, and then the clear liquid is precipitated by the clear liquid separation mechanism, and the turbid liquid is filtered by the turbid liquid separation mechanism, and the second clear liquid filtered from the turbid liquid is transported to a sedimentation tank by a conveying line for further sedimentation, thereby forming a multi-stage separation by using the above structure, and adopting different treatment methods for water with different oil contents, thereby improving the oil recovery effect and efficiency; By dividing the sedimentation tank into a clear liquid chamber and a clear water chamber, and placing multiple layers of filter membranes in the clear liquid chamber, the water and oil in the sedimentation tank are separated during sedimentation; and a distillation box is set on the mounting frame to distill the filter membrane with oil attached, so as to further improve the effect and efficiency of water-oil separation and reduce the water content in the separated oil; By setting up multiple first cylinders, the output ends of the multiple first cylinders are all connected to the edge of the filter net, and the multiple connection points are arranged at intervals along the edge of the filter net. The output ends of the first cylinders move up and down asynchronously to cause the filter net to shake, thereby improving the filtering effect and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1 -Attached Figure 6 This application is described in further detail.

[0036] The embodiment of the present application discloses a highly efficient oil separation device.

[0037] Reference Figure 1 A high-efficiency oil separation device includes a primary separation mechanism 1, a clear liquid separation mechanism 2 and a turbid liquid separation mechanism 3.

[0038] Reference Figure 1 and Figure 2 The primary separation mechanism 1 includes a raw water pipe 11, a primary separation pipe 12 and a first motor 13. The raw water pipe 11 is hollowed out, and a primary separation membrane 17 is provided on the inner wall of the raw water pipe 11. The primary separation membrane 17 is fixed to the inner wall of the raw water pipe 11 by point bonding, and the membrane holes of the primary separation membrane 17 can only allow water molecules to pass through. The primary separation pipe 12 is sleeved outside the raw water pipe 11, and there is a gap between the inner wall of the primary separation pipe 12 and the outer wall of the raw water pipe 11. The first motor 13 is installed at the end of the primary separation pipe 12, and the first motor 13 is used to drive the raw water pipe 11 to rotate. The raw water pipe 11 and the primary separation pipe 12 are both inclined, and the height of the water outlet is lower than that of the water inlet. When the raw water pipe 11 rotates, water molecules with higher density pass through the primary separation membrane 17 and the raw water pipe 11 due to centrifugal force and enter the gap between the primary separation pipe 12 and the raw water pipe 11 to form the first clear liquid, while the oil with lower density remains in the raw water pipe to form a turbid liquid with higher oil content, thereby preliminarily separating the water and oil in the raw water.

[0039] The raw water pipe 11 is coaxially connected to the rotating shaft 14, and a plurality of groups of blades 15 are arranged around the rotating shaft 14. The plurality of blades 15 in each group of blades 15 are arranged at intervals along the length direction of the rotating shaft 14, and the plurality of groups of blades 15 are arranged at intervals along the circumference of the rotating shaft 14. After the raw water enters the raw water pipe 11, under the impact of the raw water, the blades rotate relative to the raw water pipe 11, stirring the raw water and turbid liquid therein, reducing the possibility that the oil in the raw water and turbid liquid adheres to the primary separation membrane and then blocks the primary separation membrane 17. The raw water can be introduced at high pressure.

[0040] The raw water pipe 11 is also provided with a plurality of scraper plates 16, which are extended along the length direction of the raw water pipe 11, and the number of scraper plates 16 is the same as the number of groups of blades 15. The ends of the plurality of blades 15 in each group of blades 15 away from the rotating shaft 14 are all connected to the same scraper plate 16. Thus, the scraper plates 16 are driven by the blades 15 to rotate relative to the primary separation membrane 17, and the oil attached to the primary separation membrane 17 is scraped off by the scraper plates 16, further reducing the risk of oil blocking the primary separation membrane 17.

[0041] Reference Figure 3 and Figure 4 The clear liquid separation mechanism 2 includes a mounting frame 21, a rotating frame 22 and a sedimentation tank 23. The rotating frame 22 is in the shape of a round frame, and the rotating frame 22 is rotatably connected to the mounting frame 21 at the center. There are multiple sedimentation tanks 23, and the multiple sedimentation tanks 23 are connected to the rotating frame 22. The multiple sedimentation tanks 23 are arranged at equal intervals around the axis of rotation of the rotating frame 22 relative to the mounting frame 21. The multiple sedimentation tanks 23 pass under the water outlet end of the primary distribution pipe 12 in sequence during the rotation of the rotating frame 22.

[0042] A plurality of hinged rods 231 are arranged on the surface of the sedimentation tank 23 facing the rotating frame 22. The plurality of hinged rods 231 are all extended along the gravity direction of the sedimentation tank 23, and the plurality of hinged rods 231 are arranged at intervals in the horizontal direction. In this embodiment, two hinged rods 231 are arranged. One end of the hinged rod 231 is hinged to the surface of the sedimentation tank 23 facing the rotating frame 22, and the other end is hinged to the surface of the rotating frame 22 facing the sedimentation tank 23. As a result, the sedimentation tank 23 is always opened upward and relatively stable under the action of its own gravity during the movement with the rotating frame 22. On the one hand, it is convenient to receive the first clear liquid leaving the primary branch pipe 12, and on the other hand, the first clear liquid in the sedimentation tank 23 below the water outlet end leaving the primary branch pipe 12 will no longer be impacted by the first clear liquid in the primary branch pipe 12, providing a relatively stable sedimentation environment for the first clear liquid contained in these sedimentation tanks 23, ensuring the sedimentation effect.

[0043] Reference Figure 4 and Figure 5The sedimentation tank 23 is detachably connected with a hollow support plate 232 by means of a snap connection, and the support plate 232 divides the sedimentation tank 23 into an upper clear liquid chamber 235 and a lower clear water chamber 236. A multi-layer filter membrane 233 is placed on the support plate 232, and the membrane holes of the filter membrane 233 can only allow water molecules to pass through. When the sedimentation tank 23 rotates to below the water outlet end of the primary branch pipe 12, the first clear liquid flowing out of the primary branch pipe 12 enters the clear liquid chamber 235, and precipitates in the clear liquid chamber 235. While precipitating, water molecules gradually flow into the clear water chamber 236 under the action of their own gravity, thereby performing water-oil separation while precipitating, further improving the separation efficiency.

[0044] Furthermore, the sedimentation tank 23 is provided with a hose 24, and a clean water pipe 25 is provided at the middle position of the mounting frame 21, and the clean water pipe 25 is connected to the clean water collection point. One end of the hose 24 is connected to the clean water chamber 236 at the surface of the sedimentation tank 23 facing the rotating frame 22, and the other end is connected to the clean water pipe 25. A negative pressure pump is provided on the peripheral side of the clean water pipe 25, and the negative pressure pump is used to pump the clean water in the clean water chamber 236 into the clean water pipe 25, so as to collect the clean water in the clean water chamber 236 on the one hand, which is convenient for the recycling of water resources, and on the other hand, the clean water chamber 236 is emptied to reduce the weight of the sedimentation tank 23 that has been filled with the first clean liquid, thereby reducing the load of the hinged rod 231, and also allowing the rotating frame to rotate smoothly under the impact of the first clean liquid.

[0045] The mounting frame 21 is provided with a distillation box 27, which is arranged at the upper right position of the mounting frame 21. The plurality of sedimentation tanks 23 sequentially pass through the distillation chamber of the distillation box 27 during the rotation of the rotating frame 22. After the sedimentation tanks 23 enter the distillation chamber, the water on the filter membrane 233 evaporates under the heating of the distillation box 27, further reducing the water content in the separated oil and improving the oil separation effect and efficiency.

[0046] Furthermore, rigid gaskets 234 are bonded and fixed to the four corners of the filter membrane 233, and the gaskets 234 have magnetism. With this design, on the one hand, the suction force between the multiple gaskets 234 is used to establish a connection between the multiple filter membranes 233, so that the filter membranes 233 are fixed to a certain extent, and the possibility of the filter membranes 233 shifting under the impact of the first clear liquid is reduced; on the other hand, the gaskets 234 with a certain thickness are used to form a certain gap between adjacent filter membranes 233, so that when the suction cup 26 sucks the top filter membrane 233, the filter membrane 233 under the filter membrane 233 will not be moved together.

[0047] The gasket 234 may be made of stainless steel.

[0048] Reference Figure 3 and Figure 6Four second cylinders 261 are arranged at the upper position of the mounting frame 21, and the sedimentation tank 23 passes under the second cylinders 261 during the rotation process. A suction cup 26 is arranged at the output end of the second cylinder 261, and the four suction cups 26 corresponding to the four second cylinders 261 correspond to the four corners of the filter membrane 233, so that the uppermost filter membrane 233 in the sedimentation tank 23 leaving the distillation box 27 is sucked by the second cylinder 261 and the suction cup 26.

[0049] The mounting frame is further provided with a third cylinder 262 , and the four second cylinders 261 are all connected to the output end of the third cylinder 262 through a connecting rod. The third cylinder 262 is used to drive the four second cylinders 261 to move horizontally.

[0050] The mounting frame 21 is also movably connected to a container box 28, which is used to contain the filter membrane 233 captured by the second cylinder 261. In this embodiment, the container box 28 is slidably connected to the mounting frame 21 along the height direction of the mounting frame 21, and the mounting frame 21 is provided with a fourth cylinder 211, which is used to drive the container box 28 to move relative to the mounting frame 21.

[0051] The turbid liquid separation mechanism 3 includes a filter screen 31, a clear liquid pool 32 and a first cylinder 33. The filter screen 31 is used to receive the turbid liquid flowing out of the primary branch pipe 12. The mesh of the filter screen 31 is only for water molecules to pass through. The clear liquid pool 32 is used to receive the second clear liquid flowing out of the filter screen 31. A conveying line 4 is provided between the clear liquid pool 32 and the sedimentation tank 23. The conveying line 4 is used to convey the second clear liquid in the clear liquid pool 32 to the sedimentation tank 23.

[0052] In this embodiment, the filter screen 31 is made of a flexible material. A plurality of first cylinders 33 are provided, and the plurality of first cylinders 33 are vertically arranged. The output ends of the plurality of first cylinders 33 are connected to the filter screen 31, and the plurality of connection points formed between the plurality of first cylinders and the filter screen 31 are arranged at intervals along the edge of the filter screen 31.

[0053] It is understandable that the filter 31 is detachably connected to the first cylinder 33 to facilitate replacement and cleaning of the filter 31. The detachable structure can be achieved by providing a quick-release structure that cooperates with each other at the ends of the filter 31 and the first cylinder 33, or by tying.

[0054] Back to Figure 1 In this embodiment, the delivery line 4 includes a delivery pipe 41 and a delivery pump 42. One end of the delivery pipe 41 is fixedly connected to the outlet end of the primary branch pipe 12, and the other end is connected to the clear liquid pool 32. The delivery pump 42 is fixed to the peripheral side of the delivery pipe 41, and the delivery pump 42 is used to pump the second clear liquid in the clear liquid pool 32 to the location of the outlet end of the primary branch pipe 12, so as to flow into the sedimentation tank 23 for further sedimentation treatment.

[0055] The implementation principle of an efficient oil separation device is as follows: first, raw water is introduced into the raw water pipe 11, and the first motor 13 is started, and the raw water pipe 11 is driven to rotate at high speed by the first motor 13. During the rotation, water molecules with higher density pass through the hollow raw water pipe 11 and the primary separation membrane 17 due to centrifugal force and enter the gap between the raw water pipe 11 and the primary separation pipe 12 to form the first clear liquid.

[0056] At the outlet end of the primary branch pipe 12, the first clear liquid flows into the sedimentation tank 23 below the outlet end under the action of gravity. Under the impact of the first clear liquid, the sedimentation tank 23 continues to receive the first clear liquid while driving the rotating frame 22 to rotate until the next sedimentation tank 23 moves to the bottom of the outlet end.

[0057] After the sedimentation tank 23 containing the first clear liquid leaves the lower part of the water outlet, it enters the sedimentation mode. The water molecules in the clear liquid chamber 235 enter the clear water chamber 236 below through the filter membrane 233 under the action of their own gravity, and the oil is left on the filter membrane 233. (It is worth noting that in the above process, the impact force of the first clear liquid can be adjusted by adjusting the height or inclination of the primary branch pipe 12, thereby adjusting the rotation speed of the rotating frame 22; the impact force of the first clear liquid can also be adjusted by setting a delivery pump on the water pipe connected to the water outlet end of the primary branch pipe 12) Then the sedimentation tank 23 continues to rotate and enters the distillation chamber of the distillation box 27 for distillation. After leaving the distillation box 27, the sedimentation tank 23 moves to the lower part of the second cylinder 261, and the second cylinder 261 absorbs the filter membrane 233 located at the uppermost layer in the sedimentation tank 23 through the suction cup 26 at the end, and brings the filter membrane 233 into the storage box 28 for collection, and then the filter membrane 233 in the storage box 28 is taken out for further processing.

[0058] At the outlet of the raw water pipe 11, the turbid liquid flows from the raw water pipe 11 to the filter screen 31. At this time, the first cylinder 33 is started, and the ends of the multiple first cylinders 33 are moved asynchronously, so that the multiple first cylinders 33 drive the filter screen 31 to shake, filter the turbid liquid, and the filtered water flows through the filter screen 31 into the clear liquid pool 32 below to form the second clear liquid. For the filter screen 31, when the oil on it accumulates to a certain extent, it is replaced, and the oil on the replaced filter screen 31 is scraped off and collected.

[0059] The second clear liquid is transported to the sedimentation tank 23 by the transport line 4 to perform the above-mentioned sedimentation treatment.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
