DETAILED DESCRIPTION

[0023] Example 1

[0024] like Figure 1-4 As shown, a dual-mode multi-stage permeation oil purifier includes a filtering device, which is used to filter and purify oil products. The filtering device includes a shell 1, and an inlet valve 2 is arranged at one end of the shell 1. The inlet valve 2 is connected to a primary purifier 4, a secondary purifier 6, a tertiary purifier 8, a fourth-stage purifier 9, a fifth-stage purifier 10 and an oil outlet valve 11 in sequence through a pipeline. The oil outlet valve 11 is arranged at the other end of the shell 1. The third-stage purifier 8 includes an impurity removal device 81 and a water removal device 82. A valve 7 is arranged between the secondary purifier 6 and the third-stage purifier 8. The valve 7 is connected to the impurity removal device 81 and the water removal device 82 through a conduit.

[0025] When in use, the oil is filtered through the filtering device, enters through the inlet valve 2, and is detected by the humidity sensor 3, and passes through the five-stage purifier in sequence. Therefore, different oil purification modes can be selected by detecting the amount of water, thereby realizing the reasonable use of the filter element according to the usage scenario, extending the service life of each filter element, reducing losses, thereby reducing production costs, and having better economy.

[0026] In the preferred embodiment, a stainless steel magnetic filter element is provided in the first-stage purifier 4, a plurality of primary filter elements are provided in the second-stage purifier 6, a plurality of reverse osmosis filter elements are provided in the water removal device 82 in the third-stage purifier 8, a plurality of glass fiber filter elements are provided in the impurity removal device 81, a reverse osmosis glass fiber filter element is provided in the fourth-stage purifier 9, and a plurality of submicron membrane glass fiber filter elements are provided in the fifth-stage purifier 10.

[0027] The multi-stage filter element setting is based on the different sizes of impurities in the oil, the characteristics of different pollutants and the water content. The purification equipment is divided into dual-mode + five-stage purification. Each stage uses filter elements with different functions and prices to purify impurities or water of different sizes to improve purification efficiency and reduce the cost of using the filter element.

[0028] like Figure 1 The filter element water removal device 82 of the three-stage purifier 8 is provided with a plurality of reverse osmosis filter elements, at least 4, and the number of filter elements of the remaining purifiers at each stage can be 1.

[0029] The first-stage purifier 4 contains a stainless steel filter element (coarse filter before the pump), which is used to protect the oil pump and filter out large impurities. It can be cleaned regularly and does not need to be replaced.

[0030] The secondary purifier 6 contains a primary filter element, which is a 5um to 10um chemical fiber filter element, and is used to protect the service life of the subsequent filter element.

[0031] The three-stage purifier 8 has one set of 1um glass fiber filter elements for high-precision impurity removal; the other set has four 1um reverse osmosis high-efficiency filter elements for water removal and demulsification.

[0032] The fourth-stage purifier 9 is a 1um glass fiber filter element for high-precision impurity removal.

[0033] The five-stage purifier 10 is a 0.1um glass fiber filter element for submicron level fine filtration.

[0034] Each level of purifier uses a progressive filtration density to purify different impurities or water from large to small, making the oil purification effect better and more economical.

[0035] And the purifiers of each stage are arranged along the length direction of the shell 1, such as Figure 1 As shown, the filter elements are arranged reasonably and matched with the housing 1, and the structure is highly standardized; along the length direction of the housing 1, the oil purifier is suitable for a narrower site.

[0036] Furthermore, the setting principle of each level of purifiers can be: the purifiers at each level are arranged along the length direction of the shell 1, and the occupied area is minimized. According to the number of filter elements, the space of the shell 1 is reasonably distributed and used, and the shell 1 is designed to minimize the volume of the entire shell 1.

[0037] Example 2

[0038] Further illustrate with reference to Example 1, Figure 1 As shown, a humidity sensor 3 is embedded in the rear end of the inlet valve 2 .

[0039] like Figure 1-2 As shown, when the humidity sensor 3 detects that the water content in the oil is less than the preset value, for example, the water content is 1%, at this time, the valve 7 is connected to the first outlet 72, and connected to the impurity removal device 81 through the pipeline, and the second outlet 73 remains disconnected, which is a deep impurity removal mode; otherwise, the deep water removal mode is turned on, which is a way of switching between the two modes.

[0040] In the preferred embodiment, the valve 7 includes an inlet 71, a first outlet 72, and a second outlet 73, and a valve body 74 is provided at the connection point of the three. An integrated valve plate 75 and a valve core 76 are rotatably provided in the valve body 74, and a motor 13 is provided outside the valve body 74. One end of the valve core 76 penetrates the valve body 74 and is transmission-connected with the output shaft of the motor 13. The interior of the valve body 74 is a cavity, and the valve plate 75 and the valve core 76 can rotate in the valve body 74 to freely switch between the first outlet 72 and the second outlet 73.

[0041] The mode of the oil purifier can be initially set to the impurity removal mode.

[0042] In the impurity removal mode, the valve plate 75 is rotated in the valve body 74 to Figure 2 In the position shown, the first outlet is connected and the second outlet 73 is blocked.

[0043] In deep water removal mode, the motor 77 drives the valve core 76 to rotate the valve plate 75 to a preset angle, blocking the first outlet 72 and connecting the second outlet 73. When switching to the impurity removal mode again, the motor 77 reversely rotates the valve core 76 to return to the original position. Figure 2 The valve plate 75 can also be set to positive rotation control.

[0044] like Figure 5 As shown, the mode control method of switching from the impurity removal mode to the water removal mode of the utility model comprises the following steps:

[0045] S1: The initial mode of the oil purifier is the impurity removal mode.

[0046] S2: When the moisture value of the oil detected by the humidity sensor 3 is greater than a preset value, an electrical signal is transmitted to the detection device 12.

[0047] S3: After receiving the electrical signal from the humidity sensor 3 , the detection device 12 sends a control signal to the motor 13 .

[0048] S4: After receiving the control signal, the motor 13 rotates, and when the valve core 76 of the valve 7 drives the valve plate 75 to rotate by a preset angle, the second outlet 73 is connected and the first outlet 72 is closed.

[0049] S5: The oil purifier switches to water removal mode.

[0050] The above method realizes the automatic switching between the first outlet 72 and the second outlet 73. The operation method is simple, convenient, and easy to execute, which saves manpower to a great extent.

[0051] In the preferred embodiment, the valve plate 75 is a cone, the spacing between the top ends of the fan-shaped area of ​​the valve plate 75 is greater than or equal to the diameter of the pipe orifices of the first outlet 72 and the second outlet, a rubber layer 78 is provided on the outside of the fan-shaped area of ​​the valve plate 75, and an elastic device 77 is provided inside the valve plate 75, one end of the elastic device 77 is connected to the valve core 76, and the other end is connected to the rubber layer 78.

[0052] like Figure 2 As shown, the pipe diameters of the inlet 71, the first outlet 72 and the second outlet 73 of the valve 7 are all the same size d. In the impurity removal mode, the maximum spacing between the tops of the fan-shaped areas of the valve plate 75 is s. The setting conditions are:

[0053] s>d;

[0054] It is used to better isolate the second outlet 73. Theoretically, s = d for both can also be achieved.

[0055] Furthermore, the valve plate 75 may be hollow or have space reserved for the elastic device 77. The elastic device 77 is located at the diagonal line of the fan-shaped portion inside the valve plate 75, so that the operating force of the elastic device is more uniform and the effect is better.

[0056] The elastic device 77 in the valve plate 75 is connected to the rubber layer 78, and the rubber layer 78 is arranged at the outer edge of the fan-shaped area of ​​the valve plate 75 of the second outlet 73, which can better prevent the leakage of oil. The rubber can also be replaced by other flexible material components.

[0057] Example 3

[0058] Further illustrate with reference to Example 1, Figure 1 As shown, a reflux device 5 is also installed inside the housing 1. The reflux device 5 is arranged between the output end of the primary purifier 4 and the input end of the secondary purifier 6, and is connected to the oil outlet valve 11 through a pipeline. The reflux device 5 is provided with three ports, one end of which is used as an inlet at the output end of the primary purifier 4, the other end is connected to the input end of the secondary purifier 6 as an outlet, and the last end is connected to the oil outlet valve 11 through a pipeline, so that when the internal pressure of each level of purifier is too high, it can be reduced, so that the oil can penetrate into various special filter elements under a state of no pressure or slight pressure, thereby extending the life of the filter element and improving the purification efficiency.

[0059] Example 4

[0060] Further illustrate with reference to Example 1, Figure 1As shown, it also includes a safety valve 14 that penetrates the shell 1 and extends to the outside of the shell 1. An overpressure alarm device 15 is arranged on the inner wall of one side of the shell 1. The overpressure alarm device 15 is provided with a buzzer or a warning light.

[0061] In the preferred embodiment, Figure 6 As shown, it also includes a detection device 12, which is arranged outside the shell 1 and connected to the oil outlet valve 11 through a pipeline. The detection device 12 is used for real-time online monitoring and detection of filtered oil products. The detection device 12 is electrically connected to the motor 13, the humidity sensor 3, the overpressure alarm device 15 and the safety valve 14.

[0062] According to actual needs, the detection device 12 can also be installed inside the housing 1 or embedded in the housing 1. The detection device 12 exchanges information with electrical signals. When the pressure of the equipment is too high, the overpressure alarm light turns on or the buzzer buzzes, and the overpressure alarm device 15 transmits the electrical signal to the detection device 12. The detection device 12 sends an overload signal to the safety valve 14. The safety valve 14 is used for overload protection. When the pressure rises sharply and exceeds the preset pressure value, for example, 6 bar, it automatically unloads; if the alarm is still sounded, the reverse osmosis filter element should be replaced in time to ensure the operation of the equipment.

[0063] In the preferred embodiment, each purifier is provided with a sewage outlet 16, and the sewage outlet 16 is connected to a sewage valve 17 through a pipeline, and the other end of the sewage valve 17 pipeline passes through the side wall of the housing 1 and extends to the outside of the housing 1. The impurities in the filter element of each purifier remain outside the filter element and fall to the bottom of the filter barrel due to weight, and can be cleaned and discharged regularly.

[0064] Example 5

[0065] Further illustrate with reference to Examples 1-4, Figure 7 As shown, the detection device 12 includes: a sensor unit for measuring and collecting relevant technical parameters of the oil, including water content, viscosity, contamination, wear particles, saturation and oil quality.

[0066] The control unit is electrically connected to the motor 13, the humidity sensor 3, the overpressure alarm device 15 and the safety valve 14, and is used to set the technical parameters of the oil purifier and perform remote control.

[0067] The analysis and prediction unit is electrically connected to the control unit and is used to receive data and perform real-time data calculation, analysis and storage.

[0068] The monitoring and display unit is connected in communication with the analysis and prediction unit and is used for displaying various data and their analysis results in real time.

[0069] In this embodiment, the control unit can be used to set the speed and direction of the motor 13, the threshold of the humidity sensor 3, the level of the overpressure alarm device 15 such as: level one, level two and level three, the pressure threshold of the safety valve 14, etc.

[0070] According to actual needs, the sensor unit supports relevant sensors such as moisture, viscosity, contamination, wear particles, saturation, oil quality, metal abrasive particles, contamination and acid value. The sensors are connected in a building block-like manner, with high compatibility and strong scalability.

[0071] According to actual needs, the detection device 12 can also be arranged on the housing 1 or inside it.

[0072] The humidity sensor 3 transmits information to the detection device 12 through electrical signals. The detection device 12 controls the motor 13 accordingly according to different signals, thereby realizing automatic control of the valve 7 to select the corresponding outlet.

[0073] The control unit can set corresponding parameters according to different types of oil products. The utility model has been tested on more than 200 oil product models and is suitable for different industrial sites and different types of oil products.

[0074] The analysis and prediction unit is electrically connected to the control unit, and is used to receive data and perform real-time data calculation, analysis and storage. Joint processing technology is adopted, and multi-parameter fusion detection means are used to perform edge calculation, analysis and prediction on the acquired data, and conduct scientific and comprehensive analysis.

[0075] The monitoring and display unit is connected to the analysis and prediction unit for real-time display of various data and analysis results. Communication protocols such as TCP, HTTP, MB BUR, etc. are used to achieve communication interaction between the monitoring and display unit and the analysis and prediction unit, and the data used by the analysis and prediction unit, the analysis results and prediction results, and the monitoring data of various oil products are displayed in the form of intuitive curves or data. A visual display system is applied in the monitoring and display unit to support the use of mobile phones, computers and monitoring centers.

[0076] The monitoring and display unit may also be arranged on the oil purifier and electrically connected to the analysis and prediction unit to realize integrated data setting, analysis, display and control of the oil purifier.

[0077] In the prior art, this embodiment is combined with the IOL-H series intelligent online oil detection system to realize functions such as remote control, analysis and prediction, and monitoring and display.

[0078] During use, the detection device 12 collects data through the sensor unit, the control unit sets the threshold and performs corresponding control, the analysis and prediction unit performs comprehensive analysis, and the monitoring and display unit displays and detects relevant results. The four are processed together to form an online detection system for oil products.
