Description

Technical Field

[0001] The present invention relates to the technical field of filtering devices, in particular to a petroleum residue filtering device. Background Art

[0002] Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid known as the "blood of industry". Petroleum is stored in some areas of the upper crust. Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. Industrial petroleum will contain many impurities during extraction, so the extracted petroleum must be filtered to remove residues.

[0003] Current oil filtering devices generally include a filter tank body and a filter plate fixedly arranged horizontally inside the filter tank body. At the same time, an oil inlet is provided at the top of the filter tank body and an oil outlet is provided at the bottom. Oil enters from the oil inlet, is filtered by the filter plate, flows to the bottom of the filter plate, and flows out of the filter tank body from the oil outlet.

[0004] In this filtering device, the residue filtering process relies on the gravity of the oil itself, and the oil falls from top to bottom onto the filter plate to filter the residue. However, oil is generally more viscous, and when it relies on its own gravity to fall onto the filter plate for filtering, it takes a long time, so the residue filtering efficiency is low. Summary of the Invention

[0005] The invention provides a petroleum residue filtering device with high residue filtering efficiency.

[0006] The present invention provides a petroleum filter residue device, comprising a shell, a driving mechanism and a filter chamber. The shell is a hollow structure, and the inner cavity of the shell is provided with a shell oil inlet and a shell oil outlet. The filter chamber is located in the inner cavity of the shell, and the top of the filter chamber is provided with a filter chamber oil inlet. The cavity wall of the filter chamber has a filter structure for filtering petroleum. The filter chamber oil inlet is connected to the shell oil inlet. The driving mechanism is used to drive the filter chamber to rotate so that the petroleum flowing into the filter chamber passes through the filter structure under the driving force of the centrifugal force generated by the filter chamber and flows out from the shell oil outlet.

[0007] The oil filter device of the present invention uses centrifugal force to eject the oil from the filter chamber. This shortens filtration time and significantly improves filtration efficiency compared to prior art methods that rely on passive filtration under the oil's own gravity. Furthermore, the oil flowing into the filter chamber can fully contact the filter structure on the chamber wall, thereby improving the efficiency of the filter.

[0008] The construction of the present invention and other objects and advantageous effects thereof will become more apparent through the description of the preferred embodiments with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0049] In the description of the present invention specification, it should be understood that the terms "side wall", "above", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0050] In the description of the present invention, "plurality" means multiple, such as two, four, etc., unless otherwise clearly and specifically defined.

[0051] In the present invention, unless otherwise clearly specified and limited, a first feature “on” a second feature may include the first and second features being in direct contact, or the first and second features not being in direct contact but being in contact via another feature therebetween.

[0052] Figure 1 Schematic diagram of the structure of the petroleum residue filter device provided by the embodiment of the present invention. Figure 1 As shown, the petroleum filter residue device of this embodiment includes a shell 1, a driving mechanism 2 and a filter chamber 3. The shell 1 is a hollow structure, and the inner cavity of the shell 1 is provided with a shell oil inlet 11 and a shell oil outlet 12. The filter chamber 3 is located in the inner cavity of the shell 1. The top of the filter chamber 3 is provided with a filter chamber oil inlet 31. The cavity wall of the filter chamber 3 has a filtering structure for filtering petroleum. The filter chamber oil inlet 31 is connected to the shell oil inlet 11. The driving mechanism 2 is used to drive the filter chamber 3 to rotate, so that the oil flowing into the filter chamber 3 passes through the filtering structure and flows out from the shell oil outlet 12 under the driving force of the centrifugal force generated by the filter chamber 3.

[0053] Oil enters the filter chamber 3 from the housing oil inlet 11 through the filter chamber oil inlet 31. As the filter chamber 3 rotates under the drive mechanism 2, the oil within the filter chamber 3 rotates under the centrifugal force generated by the filter chamber 3 and passes through the filter structure on the wall of the filter chamber 3, flowing out of the housing oil outlet 12. During this process, the oil is thrown out of the filter chamber 3 under the action of the centrifugal force. Compared with the passive filtration of the oil under its own gravity in the prior art, the filtration time is shortened and the filtration efficiency is greatly improved. In addition, the oil that falls into the filter chamber 3 can fully contact the filter structure on the wall, thereby improving the working efficiency of the filter residue.

[0054] Specifically, a filter chamber 3 is provided within a hollow housing 1. The walls of the filter chamber 3 include a filter structure for filtering petroleum, thereby filtering the petroleum entering the filter chamber 3. The filter structure described herein can be a structure comprising small holes in the walls or a filter mesh, but the present invention is not limited thereto; any structure capable of filtering out impurities in the petroleum is acceptable. Optionally, the walls of the filter chamber 3 include sidewalls 32 and a bottom wall 33. The sidewalls 32, the bottom wall 33, or both can be configured as filter structures to optimize the filtering effect. Furthermore, a drive mechanism 2 is configured to rotate the filter chamber 3. The drive mechanism 2 can utilize a motor as a driving source, with the rotation of the motor shaft driving the rotation of the filter chamber 3. Of course, the present invention is not limited thereto and can also be implemented using other mechanisms capable of rotating the filter chamber 3. The drive mechanism 2 can be located within or outside the housing 1.

[0055] The following description will be made by taking the case where only the side wall 32 is set as the filtering structure. Figure 1 As shown, the filtering structure is disposed on the sidewall 32 of the filter chamber. The bottom wall 33 is a solid plate-like structure, on which the filtering structure is not disposed. The bottom wall of the filter chamber 3 is connected to the drive mechanism 2, which is used to drive the filter chamber 3 to rotate about a vertical axis. When the drive mechanism 2 drives the filter chamber 3 to rotate about the vertical axis, the oil in the filter chamber 3 rotates under the action of centrifugal force, and tends to escape the filter chamber 3 horizontally. As described above, configuring the sidewall 32 as a filtering structure causes the oil to be thrown onto the sidewall 32, making the filtering process more efficient.

[0056] In addition, the above technical solution is further improved in that the filter chamber 3 is conical and the small diameter end of the filter chamber 3 is arranged upward. This arrangement makes the entire filter chamber 3 in an inverted funnel shape, which makes the oil filtering effect better.

[0057] Furthermore, the drive mechanism 2 includes a motor 21, which is disposed within the housing 1 and is located below the filter chamber 3. Placing the motor 21 within the housing 1 facilitates a more compact structure for the entire device. Furthermore, locating the motor 21 below the filter chamber 3 minimizes the distance between the motor 21 and the filter chamber 3, thereby reducing the number of transmission mechanisms between the motor 21 and the filter chamber 3 and the size of the transmission mechanisms. Optionally, the drive mechanism 2 also includes a rotating shaft 22 and a coupling (not shown). The motor shaft of the motor 21 is connected to the rotating shaft 22 via the coupling, serving as a connecting component. The end of the rotating shaft 22 not connected to the motor shaft is engaged with the bottom wall 33. Thus, when the motor 21 rotates, the bottom wall 33 is driven to rotate. Of course, to prevent the influence of oil on the drive mechanism 2, particularly the motor 21, a motor sealing chamber 23 is also fixedly connected to the housing 1. The motor sealing chamber 23 seals the motor 21 and the coupling, with only the rotating shaft 22 extending from the motor sealing chamber 23 and engaging the bottom wall 33. In addition, the motor shaft of the motor 21 may be directly engaged with the bottom wall 33 , and at the same time support the bottom wall 33 , which can further reduce the number of parts and is conducive to miniaturization of the entire device.

[0058] In the above technical solution, the shell oil inlet 11 is fixed relative to the shell 1, and the filter chamber oil inlet 31 is also fixed relative to the filter chamber 3. Since the driving mechanism 2 drives the filter chamber 3 to rotate relative to the shell 1, the shell oil inlet 11 and the filter chamber oil inlet 31 are required to be able to rotate relative to each other.

[0059] To achieve the above-mentioned purpose, the shell oil inlet 11 and the filter chamber oil inlet 31 may be arranged in a structure that is not connected in the radial direction but overlaps in the vertical direction. Specifically, the shell oil inlet 11 includes a shell oil inlet pipe extending into the interior of the shell 1, and the filter chamber oil inlet 31 includes a filter chamber oil inlet pipe extending in a direction away from the filter chamber 3. The free end of the shell oil inlet pipe is inserted into the free end of the filter chamber oil inlet pipe, but the two do not contact each other in the radial direction. In this arrangement, during the filtering process, the drive mechanism 2 drives the filter chamber 3 to rotate relative to the shell 1, and the filter chamber oil inlet pipe also rotates relative to the fixed shell oil inlet pipe. At the same time, oil continuously enters the filter chamber 3 through the shell oil inlet 11, the shell oil inlet pipe, the filter chamber oil inlet pipe, and the filter chamber oil inlet 31 for filtration. In this technical solution, the filter chamber 3 can be optionally fixed on the rotating shaft 22. However, there is a risk that the oil in the filter chamber 3 will flow out through the gap between the oil inlet pipe of the shell and the oil inlet pipe of the filter chamber.

[0060] Therefore, it is possible to consider rotatably connecting the filter chamber oil inlet 31 and the housing oil inlet 11. This can prevent the petroleum liquid in the filter chamber 3 from splashing out of the filter chamber oil inlet due to the rotation of the filter chamber 3, causing pollution.

[0061] In actual operation, optionally, the housing oil inlet 11 and the filter chamber oil inlet 31 are rotatably connected via the connector 5 . Figure 2 This is a schematic diagram of the exploded structure of a connector in a petroleum residue filter device provided by an embodiment of the present invention; Figure 3 Schematic diagram of the structure of the connector in the petroleum filter residue device provided by the embodiment of the present invention. Figure 2 、 3 As shown, the oil inlet 11 of the housing and the oil inlet 31 of the filter chamber are connected by a connector 5. The connector 5 includes an upper coupler 51 fixedly connected to the oil inlet 11 of the housing and a lower coupler 52 fixedly connected to the oil inlet 31 of the filter chamber. The upper coupler 51 and the lower coupler 52 are coaxially arranged up and down. The upper coupler 51 is a rotating body, and the lower coupler 52 includes a main body 521 of the rotating body and a plurality of limiting posts 522 arranged at the top of the main body 521. The plurality of limiting posts 522 are arranged along the circumference of the main body 521. The upper and lower couplings 51 are connected to each other in a circular manner, and the upper and lower couplings 51 are connected to each other in a circular manner.

[0062] In the above embodiment, the limiting portion 523 is retained within the annular groove 511, limiting the vertical relative movement of the lower and upper clutches 52 and 51. Simultaneously, the limiting post 522 abuts against the outer sidewall of the upper clutch 51, limiting the horizontal relative movement of the lower and upper clutches 52 and 51. Optionally, the vertical dimension of the upper clutch 51 is equal to the vertical height of the limiting post 522. Thus, when the limiting portion 523 is retained within the annular groove 511 and the limiting post 522 abuts against the outer sidewall of the upper clutch 51, the lower surface of the upper clutch 51 is in close contact with the upper surface of the lower clutch 52, thereby preventing oil leakage. During the filtration process, the driving mechanism 2 drives the filter chamber 3 to rotate relative to the shell 1, and the lower coupler 52 rotates relative to the upper coupler 51. Specifically, the limiting portion 523 rotates within the annular groove 511, and the limiting column 522 rotates closely against the outer side of the side wall of the upper coupler 51. The lower surface of the upper coupler 51 and the upper surface of the lower coupler 52 are always in close contact during the relative rotation of the two, so that oil will not leak.

[0063] In addition, in order to enhance the sealing effect of the upper closer 51 and the lower closer 52 , a sealing gasket 53 may be optionally provided between the upper closer 51 and the lower closer 52 .

[0064] exist Figure 2 、 3 The figure shows an example of four limiting posts 522 evenly distributed in the circumferential direction, but another number of limiting posts 522, such as two or three, may be provided as needed. Furthermore, the limiting posts 522 may be integrally formed with the body 521 or formed separately. For example, the limiting posts 522 may be bolts, and a plurality of threaded holes having a diameter matching the diameter of the bolt shank may be provided on the end surface of the body 521. The bolts are installed in the threaded holes to form the aforementioned limiting post structure.

[0065] Optionally, a check valve 54 can be provided between the upper coupler 51 and the oil inlet 11 of the housing. The check valve 54 can prevent the oil from flowing back or splashing out of the oil filter device during the filtration process, thereby reducing the waste of oil during the filtration process.

[0066] In addition, a baffle 4 is optionally provided between the inner wall of the housing 1 and the housing oil inlet 11. The baffle 4 is located above the filter chamber 3. The baffle 4 is annular, and the inner edge of the baffle 4 is higher than the outer edge of the baffle 4. The baffle is provided above the filter chamber 3 to deflect as much as possible the petroleum droplets splashing from the side wall 32, preventing the petroleum from contacting and adhering to the inner wall of the entire housing 1, thereby reducing the contamination and damage of the petroleum residue filter device by the petroleum. The baffle 4 is annular in shape in order to block the petroleum droplets splashing in all directions. When the petroleum droplets splashing onto the baffle 4 adhere to the baffle 4, since the inner edge of the baffle 4 is higher than the outer edge of the baffle 4, that is, the baffle 4 is tilted upward, multiple oil droplets can flow obliquely downward along the baffle 4 under the action of their own gravity, and finally converge at the connection part between the baffle 4 and the shell 1, and then continue to flow downward along the inner wall of the shell 1. In this process, the oil droplets can be minimized from directly falling on the side wall 32 below the baffle 4, thereby reducing the impact on the petroleum filtration process.

[0067] Optionally, a gas overflow port 6 is provided on the housing 1, and an air purifier 61 is also provided on the gas overflow port 6. A fan 62 is also provided on the side of the air purifier 61 near the interior of the housing 1. The housing 1 is typically provided with a gas overflow port 6 to facilitate the discharge of gas mixed with the oil from the gas overflow port 6. However, the odor of this gas is generally strong and can easily pollute the environment around the oil filter. By providing the air purifier 61 on the gas overflow port 6, the gas within the housing 1 can be purified before being discharged from the housing 1, thereby preventing environmental pollution caused by the odor of the oil. In addition, by providing the fan 62 and controlling the rotation direction of the fan 62, the gas within the housing 1 can be discharged outside the housing 1.

[0068] Furthermore, during the filtration process, oil comes into contact with air. Consequently, the oil often contains air, which can affect the accuracy of the filtered residue. To prevent this, a partition 8 can be provided at the lower portion of the housing 1. This partition 8 divides the interior of the housing 1 into an upper residue chamber 82 and a lower oil return chamber 83. The residue chamber 82 communicates with the housing's oil inlet 11, while the oil return chamber 83 communicates with the housing's oil outlet 12. The filter chamber 3 is disposed within the residue chamber 82, and the residue chamber 82 and the oil return chamber 83 are connected via an oil compressor 81 disposed on the partition 8. With this arrangement, after filtering the oil in the filter chamber 3, the oil flows to the bottom of the residue chamber 82, where it is compressed by the oil compressor 81, expelling the gas contained therein. The oil then enters the oil return chamber 83 and finally exits the oil filter through the housing's oil outlet 12. Two oil compressors 81 can be positioned opposite each other on the partition 8 to ensure uniform compression of the oil. In this way, the oil is compressed by the oil compressor 81, so that the gas inside the oil can be separated from the oil, thereby improving the accuracy of the oil after the filter residue work.

[0069] In the above technical solution, the housing 1 can also be configured as a split upper and lower structure. Specifically, the filter chamber 82 and the oil return chamber 83 can be provided separately, and the filter chamber 82 and the oil return chamber 83 can be connected by a bolt assembly 84. This facilitates the installation and maintenance of components within the housing 1. For example, after a period of oil filter residue removal, the bolt assembly 84 can be removed to inspect and maintain the various components within the housing 1.

[0070] After the petroleum filter residue device as described above has been operating for a period of time, a certain amount of residue will accumulate in the filter chamber. If it is not cleaned in time, the working efficiency of the petroleum filter residue device will be affected. Figure 4 yes Figure 1 A partial enlarged view of component A; Figure 5 yes Figure 1 A partial enlarged view of component B. Figure 4 、 5 As shown, as an optional embodiment, an openable and closable valve 34 and an infrared receiver 35 are provided on the bottom wall 33 of the filter chamber 3. An infrared transmitter 36 is provided on the partition 8 opposite the infrared receiver 35. The valve 34 and the infrared receiver 35 are electrically connected. The infrared transmitter 36 is electrically connected to an external controller and is configured to emit infrared signals under the control of the external controller. The infrared receiver 35 is configured to control the opening and closing of the valve 34 upon receiving the infrared signal from the infrared transmitter 36. In this embodiment, when the openable and closable valve 34 is opened, the residue in the filter chamber 3 can be discharged through the opened valve 34. The valve 34 can be electrically controlled, with its opening and closing controlled by the infrared receiver 35.

[0071] Specifically, the external controller controls the infrared emitter 36 to emit infrared rays, and after the infrared receiver 35 receives the infrared rays, it controls the valve 34 to open or close, thereby facilitating the cleaning of the residue in the bottom wall 33 and improving the residue cleaning capacity of the petroleum filter device.

[0072] Of course, while the example herein illustrates the use of an external controller to control the opening and closing of valve 34, a manipulator 91 can also be provided on housing 1 as an external controller. Here, manipulator 91 is integrated with the petroleum residue filter device and can be used to start or stop motor 21 or to adjust the speed of motor 21 to control the rotational speed of filter chamber 3. Alternatively, an external remote control can be used to control the infrared emitter 36 to emit infrared rays, thereby controlling the opening and closing of valve 34. Such variations fall within the scope of protection of the present invention.

[0073] In addition, an oil pump 9 can be optionally connected to the oil outlet 12 of the shell. When the oil pump 9 is working, the oil that has been filtered at the bottom of the shell 1 can be discharged from the shell 1 in time, preventing the filtered oil from being retained at the bottom of the shell 1 and allowing it to be discharged in time, which can speed up the filtration process and improve the working efficiency of the oil filter residue device.

[0074] The working process of the petroleum residue filter device of this embodiment will be described in detail below.

[0075] During use, first, the motor 21 is started via the controller 91, causing the motor 21 to drive the filter chamber 3 to rotate and centrifuge via the rotating shaft 22, while simultaneously starting the fan 62 and the air purifier 61. After the pretreatment is completed, the oil to be filtered is connected to the housing's oil inlet 11. After passing through the check valve 3 and the connector 5, the oil falls onto the bottom wall 33 of the filter chamber 3. Under the action of the rotating centrifugal force of the filter chamber 3, the oil is able to fully contact and filter the side walls 32. After passing through the side walls 32, the oil is thrown out of the filter chamber 3, splashing onto the baffle 4, and sliding along the inclined baffle 4 to the inner wall of the housing 1, and then flowing to the bottom of the filter chamber 82. The oil flowing to the bottom of the filter chamber 82 is compressed by the oil compressor 81, causing the gas inside the oil to separate from the oil, thereby improving the accuracy of the oil after the filter operation. The oil that has passed through the oil compressor 81 enters the oil return chamber 83 and is discharged from the oil filter device through the housing oil outlet 12 and the oil pump 9 provided at the bottom of the housing 1 .

[0076] During the above-mentioned filtering process, the fan 62 can absorb the gas in the shell 1 and transport the gas to the air purifier 61. The air purifier 61 will purify the gas and then discharge it from the oil filter device, thereby avoiding the pollution of the surrounding environment by the smell of oil and greatly improving the working environment of the staff. In addition, the oil compressor 81 can compress the oil after the filter residue, so that the gas inside the oil is separated from the oil, thereby improving the accuracy of the oil after the filter residue work, and the filtered oil can finally be discharged from the device at a faster speed through the oil pump 9.

[0077] After the work is completed, the operator can activate the infrared transmitter 36 through the controller 4, which can then control the infrared receiver 35 to open the valve 34 when the signal is in contact, thereby facilitating the cleaning of the residue in the filter chamber 3. After a certain period of work, the filter chamber 82 and the oil return chamber 83 can be separated by removing the bolt assembly 84, thereby performing regular cleaning and maintenance on the oil filter device, thereby improving the device's sustainable working capacity.

[0078] The petroleum residue filter device of this embodiment includes a housing, a drive mechanism, and a filter chamber. The housing is a hollow structure, and its inner cavity is provided with a housing oil inlet and a housing oil outlet. The filter chamber is located within the inner cavity of the housing. The filter chamber has a filter chamber oil inlet at its top end. The wall of the filter chamber has a filter structure for filtering the petroleum. The filter chamber oil inlet is connected to the housing oil inlet. The drive mechanism is used to drive the filter chamber to rotate so that the petroleum flowing into the filter chamber is driven by the centrifugal force generated by the filter chamber to pass through the filter structure and flow out of the housing oil outlet. Since the petroleum in the filter chamber is ejected from the filter chamber by the centrifugal force of the filter chamber, compared with the passive filtration method of the prior art that relies on the petroleum's own gravity, the filtration time is shortened, greatly improving the filtration efficiency.
