Description

Technical Field

[0001] This utility model relates to a self-cleaning oil filter, belonging to the technical field of oil filter equipment. Background Technology

[0002] The high-speed operation of industrial equipment causes the mechanical oil to atomize and vaporize, mixing with the exhaust gas. It is necessary to filter the exhaust gas for oil contamination. For example, a pulse backwash oil filter mentioned in announcement number CN211462408U discloses that the filter box has an air inlet on the lower right side and an air outlet on the upper left side. The filter box has a high-efficiency filter, a medium-efficiency filter and a pre-filter arranged horizontally from top to bottom. The high-efficiency filter is lower than the air outlet and the pre-filter is higher than the air inlet. The oil filter also includes a backwashing device and an airflow guide plate. The backwashing device includes a pulse solenoid valve and a backwash pipe. The pulse solenoid valve is located on the left side of the filter box and on the left end of the backwash pipe.

[0003] In the aforementioned device, the primary filter with the most oil residue is self-cleaned by air jet. However, in actual application, researchers found that the oil residue is very sticky, and self-cleaning by air jet alone is not effective and cannot be easily scraped off, which is not conducive to its widespread use. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a self-cleaning oil filter.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning oil filter, comprising a filter box, an inspection port extending through one side surface of the filter box, a baffle plate slidably connected to the outer surface of the inspection port, a baffle electric push rod fixedly connected to the top surface of the baffle plate, a guide rail box fixedly connected through the front surface of the filter box, a servo motor fixedly connected to one end of the guide rail box, a threaded rod provided in the inner cavity of the guide rail box, a moving plate slidably connected to the rear surface of the guide rail box, an installation groove provided on the top surface of the moving plate, an installation block movably connected to the inner surface of the installation groove, an installation bolt threadedly connected to one side surface of the installation block, a scraper fixedly connected to the top surface of the installation block, a primary filter fixedly connected to the inner cavity of the filter box, a medium-efficiency filter above the primary filter, and a high-efficiency filter above the medium-efficiency filter.

[0006] As a further optimization, the top surface of the inner cavity of the inspection port is flush with the bottom surface of the primary filter, and the inspection port is matched with the structural dimensions of the baffle plate.

[0007] As a further optimization, one side surface of the baffle is slidably connected to the filter box, the top surface of the baffle is fixedly connected to the telescopic end of the baffle electric push rod, and the outer surface of the sleeve end of the baffle electric push rod is fixedly connected to the filter box.

[0008] As a further optimization, one end of the threaded rod is fixedly connected to the output end of the servo motor, and the end of the threaded rod away from the servo motor is movably connected to the guide rail box through a bearing.

[0009] As a further optimization, a first sliding block is fixedly connected to the front surface of the motion plate. The first sliding block is threadedly connected to the outer surface of the threaded rod. A groove matching the structural size of the first sliding block is opened on the rear surface of the guide box.

[0010] As a further optimization, a second sliding block is fixedly connected to the rear surface of the motion plate, and a groove matching the structural dimensions of the second sliding block is opened on the rear surface of the inner cavity of the filter box.

[0011] As a further optimization, the mounting groove is matched with the structural dimensions of the mounting block, and a threaded hole matching the structural dimensions of the mounting bolt is provided on the rear surface of the inner cavity of the mounting groove.

[0012] Compared with existing technologies, the advantages of this utility model are as follows: By setting up an inspection port, a baffle plate, a baffle electric push rod, a guide rail box, a servo motor, a threaded rod, a moving plate, a mounting groove, a mounting block, mounting bolts, and a scraper, the primary filter with the most oil stains can be scraped and cleaned, resulting in better cleaning. Furthermore, it allows for convenient disassembly and replacement of worn scraping contact structures, making it more user-friendly. During use, the servo motor drives the threaded rod to rotate. As the threaded rod rotates, the first sliding block, the moving plate, and the scraper assembly reciprocate along the guide rail box, thereby scraping and cleaning the oil stains on the bottom surface of the primary filter, resulting in better cleaning. When it is necessary to replace a worn scraper, the baffle electric push rod is retracted to move the baffle plate, exposing the inspection port. Then, the mounting bolts are removed to replace the scraper, making it more user-friendly. Attached Figure Description

A guide rail box 5 is fixedly connected through the front surface of the filter box 1. A servo motor 6 is fixedly connected to one end of the guide rail box 5. A threaded rod 7 is provided inside the guide rail box 5. A moving plate 8 is slidably connected to the rear surface of the guide rail box 5. A mounting groove 9 is provided on the top surface of the moving plate 8. A mounting block 10 is movably connected to the inner surface of the mounting groove 9. A mounting bolt 11 is threaded through one side surface of the mounting block 10. A scraper 12 is fixedly connected to the top surface of the mounting block 10. A primary filter 13 is fixedly connected inside the filter box 1. A medium-efficiency filter 14 is provided above the primary filter 13. A high-efficiency filter 15 is provided above the medium-efficiency filter 14.

[0022] In use, exhaust gas is first introduced into the filter box 1 through the intake pipe. After being filtered by the pre-filter 13, medium-efficiency filter 14 and high-efficiency filter 15, the oil in the exhaust gas is separated. The water spray pipe on the pre-filter 13 sprays out mist, which allows the pre-filter 13 to capture the oil. The oil will adhere to the bottom surface of the pre-filter 13. The air jet pipe on the pre-filter 13 sprays out high-pressure gas to clean the pre-filter 13 and prevent clogging.

[0023] Furthermore, the vertical cross-section of the moving plate 8 is triangular, and both the scraper 12 and the outer surface of the moving plate 8 are smooth polished surfaces. The top surface of the scraper 12 is slidably connected to the bottom surface of the primary filter 13.

[0024] It should be noted that: an air outlet pipe and a water spray pipe are provided between the pre-filter 13 and the medium-efficiency filter 14. One end of the air outlet pipe and the water spray pipe are both fixedly connected to the filter box 1. The end of the air outlet pipe away from the filter box 1 is fixedly connected to a known air supply device, and the end of the water spray pipe away from the filter box 1 is fixedly connected to a known external water supply device. An air nozzle is fixedly connected to the bottom surface of the air outlet pipe, which can generate high-pressure air to clean the pre-filter 13. A spray head is fixedly connected to the bottom surface of the water spray pipe, which sprays water mist to facilitate the capture of oil stains by the pre-filter 13.

[0025] An air inlet pipe is fixedly connected through the lower part of one side surface of filter box 1, and an air outlet pipe is fixedly connected through the upper part of one side surface of filter box 1.

[0026] As a preferred technical solution in this embodiment, the top surface of the inner cavity of the inspection port 2 is flush with the bottom surface of the primary filter 13, and the structural dimensions of the inspection port 2 and the baffle plate 3 are matched; the location of the inspection port 2 is explained to facilitate the removal of the scraper 12.

[0027] As a preferred technical solution in this embodiment, one side surface of the baffle plate 3 is slidably connected to the filter box 1, the top surface of the baffle plate 3 is fixedly connected to the telescopic end of the baffle electric push rod 4, and the outer surface of the sleeve end of the baffle electric push rod 4 is fixedly connected to the filter box 1; the telescopic extension of the baffle electric push rod 4 can drive the movement of the baffle plate 3.

[0028] As a preferred technical solution in this embodiment, the mounting groove 9 and the mounting block 10 are matched in structural dimensions. The rear surface of the inner cavity of the mounting groove 9 is provided with a threaded hole that matches the structural dimensions of the mounting bolt 11. The mounting block 10 is installed in the mounting groove 9 and is tightened by rotating the mounting bolt 11 to limit the position of the mounting block 10.

[0029] Example 2

[0030] Please see Figure 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that:

[0031] One end of the threaded rod 7 is fixedly connected to the output end of the servo motor 6, and the other end of the threaded rod 7 away from the servo motor 6 is movably connected to the guide rail box 5 through a bearing. A first sliding block 16 is fixedly connected to the front surface of the motion plate 8. The first sliding block 16 is threadedly connected to the outer surface of the threaded rod 7. A groove matching the structural dimensions of the first sliding block 16 is opened on the rear surface of the guide rail box 5. A second sliding block 17 is fixedly connected to the rear surface of the motion plate 8. A groove matching the structural dimensions of the second sliding block 17 is opened on the rear surface of the inner cavity of the filter box 1. The servo motor 6 is controlled to drive the rotation of the threaded rod 7. At this time, as the rotation direction of the threaded rod 7 is different, the combination of the first sliding block 16, the motion plate 8 and the scraper 12 performs reciprocating motion in the direction of the guide rail box 5. The second sliding block 17 is engaged and slidably connected to the filter box 1 to prevent the motion plate 8 from shaking during the movement.

[0032] It should be noted that, with the help of those skilled in the art, all electrical components in this case, such as the electric push rod 4 and the servo motor 6, and their compatible power supplies, should be connected by wires. Furthermore, a suitable controller, such as a PLC controller or a microcontroller, should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the field. The following mainly introduces the working principle and process, without further explanation of the electrical control.

[0033] The working principle and usage process of this utility model are as follows: When using it, while cleaning the primary filter 13 with air jets, the servo motor 6 is controlled to drive the rotation of the threaded rod 7. At this time, as the threaded rod 7 rotates, the first sliding block 16, the moving plate 8 and the scraper 12 assembly reciprocate in the direction of the guide box 5, thereby scraping and cleaning the oil stains on the bottom surface of the primary filter 13, resulting in a better cleaning effect. Furthermore, when it is necessary to replace the worn scraper 12, the electric push rod 4 is controlled to retract, driving the movement of the baffle plate 3 to expose the inspection port 2. Then, the mounting bolt 11 is removed and the scraper 12 is replaced.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
