Description

Technical Field

[0001] This application relates to the field of liquid filtration equipment technology, and in particular to a liquid carbon source filtration device with an anti-clogging structure. Background Technology

[0002] In many industrial fields such as wastewater treatment and bio-fermentation, liquid carbon sources are key raw materials, and their quality directly affects the effectiveness and quality of the entire production process. Before using liquid carbon sources, they must be filtered to remove impurities, preventing damage to subsequent process equipment or impact on product quality.

[0003] Traditional liquid carbon source filtration devices typically employ fixed filtration structures, such as single filter screens or plates. Over long-term use, these structures are highly susceptible to clogging by impurities, leading to a significant decrease in filtration efficiency. This not only necessitates frequent replacement of filter components, increasing production costs, but can also force production interruptions, impacting production continuity. Furthermore, traditional filtration devices generally only offer single-precision filtration, failing to meet the varying filtration precision requirements of different production processes. Additionally, some filtration devices with cleaning functions exhibit poor cleaning performance, failing to effectively remove impurities adhering to the filter structure, thus perpetuating the clogging problem.

[0004] Therefore, a liquid carbon source filtration device with an anti-clogging structure is invented to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a liquid carbon source filtration device with an anti-clogging structure to solve the problems of easy clogging and limited filtration accuracy of existing liquid carbon source filtration devices.

[0006] This application provides a liquid carbon source filtration device with an anti-clogging structure, which adopts the following technical solution: it includes a filter box, wherein an inlet is opened on one side and an outlet is opened on the other side of the filter box. The filter box is provided with a filter assembly for filtering liquid carbon sources. The filter assembly includes a filter shell, the filter shell includes a fixed frame and filter plates. The fixed frame is fixed in the middle of the filter box. Sliding filter plates are respectively arranged on both sides of the fixed frame. Filter holes are evenly distributed in the vertical direction on both sides of the filter shell. A cleaning assembly for cleaning the filter holes is provided inside the filter shell.

[0007] Optionally, the filter housing is located in the middle of the filter box, the filter holes on both sides of the filter box are of different sizes, and the size of the filter hole on the side of the filter housing closer to the feed inlet is smaller than the size of the filter hole on the side closer to the discharge outlet.

[0008] Optionally, the cleaning component includes a drive motor, the output end of which is provided with a rotating screw. The rotating screw is rotatably connected inside the filter box. A sliding frame is threadedly connected to the rotating screw. The sliding frame is slidably connected to the filter shell. A push ball that can slide into the filter hole is provided on the sliding frame. When the push ball moves up and down, it can drive the push ball to slide into different filter holes.

[0009] Optionally, the sliding frame is provided with a fixed cylinder, and a sliding cylinder is slidably disposed inside the fixed cylinder. A first compression spring is disposed inside the sliding cylinder, and the other end of the first compression spring is fixedly connected to the fixed cylinder. A limit groove is started at the other end of the sliding cylinder, and the push ball can move within the limit groove.

[0010] Optionally, a guide slope is provided on one side of the filter hole located inside the filter shell.

[0011] Optionally, a number of second compression springs are fixedly connected between the filter plate and the fixed frame.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. Significant anti-clogging effect: By setting up a cleaning component, the push ball can clean the filter holes one by one during its up and down movement, effectively preventing the filter holes from being blocked by impurities, ensuring the filtration efficiency and stability of the filtration device, and reducing equipment maintenance and replacement costs caused by clogging.

[0014] 2. Multi-stage filtration: The filter holes on both sides of the filter housing are of different sizes. The liquid carbon source is first filtered through the small-sized filter holes for preliminary filtration, and then through the large-sized filter holes for secondary filtration. This meets the different filtration precision requirements of different production processes for liquid carbon sources and improves the filtration quality.

[0015] 3. The filter plate is slidable and automatically resets via a second compression spring, enabling it to filter liquid carbon sources with varying impurity contents. Simultaneously, the sliding cylinder and first compression spring ensure that the push ball can smoothly slide into the filter holes, improving the cleaning effect. Attached Figure Description

In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model.

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 One embodiment shown is as follows: The filtration device comprises a filter box 1. Inside the filter box 1, there is an inlet 2 on one side and an outlet 3 on the other side. In this embodiment, the inlet 2 is located on the upper side of the filter box 1, and the outlet 3 is located on the lower side of the filter box 1. The inlet 2 and outlet 3 serve as inlet and outlet channels for the liquid carbon source, allowing the liquid carbon source to be filtered within the filter box 1. A filter assembly 4 is installed inside the filter box 1. This filter assembly 4 includes a filter shell 5, which is composed of a fixed frame 6 and two filter plates 7. The fixed frame 6 is installed in the middle of the filter box 1 by welding or other fixing methods. This fixing method ensures the stability of the fixed frame 6 within the filter box 1, thereby ensuring the stable operation of the entire filter assembly 4. Sliding filter plates 7 are installed on both sides inside the fixed frame 6. The filter plates 7 are connected to the fixed frame 6 using a sliding rail and slider mechanism, allowing the filter plates 7 to slide in a specific direction within the fixed frame 6. Multiple filter holes 8, evenly distributed along the vertical direction, are provided on both sides of the filter housing 5. These filter holes 8 are the key channels for filtering liquid carbon sources. A cleaning component 9 is installed inside the filter housing 5 for cleaning the filter holes 8.

[0025] The implementation principle of the above embodiment is as follows: the liquid carbon source enters the filter box 1 from the inlet 2 and is filtered through the filter holes 8 on both sides of the filter shell 5. Impurities are intercepted by the filter plate 7. During the filtration process, the cleaning component 9 cleans the filter holes 8 to prevent impurities from clogging them. The filtered liquid carbon source flows out from the outlet 3.

[0026] Reference Figure 2 , Figure 3 One embodiment shown depicts a filter housing 5 positioned in the center of the filter box 1. The filter holes 8 on both sides of the filter housing 5 have different sizes; the filter holes 8 closer to the inlet 2 are relatively smaller, while those closer to the outlet 3 are relatively larger. In this embodiment, the filter housing 5 is fixedly installed inside the filter box 1 to maintain its stability within the filter box 1.

[0027] The implementation principle of the above embodiment is as follows: after the liquid carbon source enters from the inlet 2, it first undergoes preliminary filtration through a smaller filter hole 8 on the side closer to the inlet 2, and then undergoes secondary filtration through a larger filter hole 8 on the side closer to the outlet 3, thereby achieving multi-stage filtration of the liquid carbon source and improving the filtration effect.

[0028] Reference Figure 5 , Figure 6 One embodiment shown is as follows: the cleaning assembly 9 includes a drive motor 14, the output end of which is fixedly connected to a rotating screw 15, enabling the drive motor 14 to drive the rotating screw 15 to rotate. The rotating screw 15 is mounted inside the filter box 1 via rotating connecting components such as bearings (threads are not shown in the figure), ensuring that the rotating screw 15 can rotate smoothly within the filter box 1. A sliding frame 16 is installed on the rotating screw 15 via a threaded connection, which allows the rotation of the rotating screw 15 to be converted into the linear motion of the sliding frame 16. The sliding frame 16 and the filter shell 5 are slidably connected via a slide rail and slider, ensuring the stability of the sliding frame 16 during movement. The movement of the sliding frame 16 allows the push ball 17 to slide into the filter hole 8.

[0029] The implementation principle of the above embodiment is as follows: the drive motor 14 starts and drives the rotating screw 15 to rotate. The rotation of the rotating screw 15 causes the sliding frame 16 to move up and down along its axis. During the movement of the sliding frame 16, the push ball 17 moves up and down. During the up and down movement, the push ball 17 slides into different filter holes 8 to clean the filter holes 8.

[0030] Reference Figure 5 , Figure 6One embodiment shown is as follows: A fixed cylinder 10 is fixedly connected to the sliding frame 16 of the cleaning component 9. A sliding cylinder 11 is slidably disposed inside the fixed cylinder 10. The sliding cylinder 11 and the fixed cylinder 10 are slidably connected through a gap fit between their cylinder walls. This connection method ensures that the sliding cylinder 11 can slide smoothly within the fixed cylinder 10. A first compression spring 12 is provided inside the sliding cylinder 11. One end of the first compression spring 12 is fixedly connected to the sliding cylinder 11, and the other end is fixedly connected to the fixed cylinder 10. The first compression spring 12 provides an elastic force to the sliding cylinder 11. A limiting groove 13 is formed at the other end of the sliding cylinder 11. A push ball 17 can move within the limiting groove 13. The push ball 17 and the limiting groove 13 are movably connected through the cooperation of the ball and the groove, so that the push ball 17 can move within the limiting groove 13 without detaching from the sliding cylinder 11.

[0031] The implementation principle of the above embodiment is as follows: when the sliding frame 16 moves, it drives the fixed cylinder 10 to move. The fixed cylinder 10 drives the sliding cylinder 11 to move through the first compression spring 12. The sliding cylinder 11 then drives the push ball 17 to move. The elastic effect of the first compression spring 12 keeps the push ball 17 moving towards the filter hole 8, ensuring that the push ball 17 can smoothly slide into the filter hole 8 for cleaning.

[0032] Reference Figure 6 One embodiment shown is as follows: a guide slope 18 is provided on one side inside the filter shell 5 within the filter hole 8. In this embodiment, the guide slope 18 is directly machined onto the inner wall of the filter hole 8 as part of the filter hole 8 structure.

[0033] The implementation principle of the above embodiment is as follows: when the push ball 17 slides toward the filter hole 8, the guide slope 18 can guide the push ball 17 to slide smoothly into the filter hole 8, reduce the resistance of the push ball 17 sliding into the filter hole 8, and improve the cleaning efficiency of the cleaning component 9 on the filter hole 8.

[0034] Reference Figure 1 , Figure 2 , Figure 5 One embodiment shown is that a plurality of second compression springs 19 are fixedly connected between the filter plate 7 and the fixed frame 6. In this embodiment, the two ends of the second compression springs 19 are fixedly connected to the filter plate 7 and the fixed frame 6 respectively, for example by welding or bolting.

[0035] The implementation principle of the above embodiment is as follows: when a lot of impurities are attached to the filter plate 7, it slides into the fixed frame 6 under the pressure of the liquid, compressing the second compression spring 19; after the impurities are cleaned, under the elastic force of the second compression spring 19, the filter plate 7 returns to the initial position and continues to perform filtration. The setting of the second compression spring 19 enables the filter plate 7 to adapt to the accumulation of impurities, ensuring the filtration effect. At the same time, the setting of the second compression spring 19 enables the filter plate 7 to vibrate, improving the anti-clogging effect.

[0036] The working principle of this device is as follows: The drive motor 14 is started, and the motor output drives the rotating screw 15 to rotate. The rotating screw 15 is threadedly connected to the sliding frame 16, converting the rotation into the up-and-down linear motion of the sliding frame 16. The sliding frame 16 and the filter shell 5 are slidably connected via a slide rail slider to ensure motion stability. The fixed cylinder 10 on the sliding frame 16 moves synchronously with the sliding frame 16. The sliding cylinder 11 inside the fixed cylinder 10, under the action of the first compression spring 12, constantly pushes the push ball 17 towards the filter hole 8. The limiting groove 13 at the end of the sliding cylinder 11 restricts the position of the push ball 17, allowing it to move within the groove.

[0037] As the pusher ball 17 moves with the sliding frame 16, the guide slope 18 inside the filter hole 8 guides the pusher ball 17 to slide smoothly in, pushing out the blockage impurities. At the same time, if the filter plate 7 intercepts too many impurities, under liquid pressure, the filter plate 7 will slide into the fixed frame 6, compressing the second compression spring 19; after the impurities are cleared, the elastic force of the second compression spring 19 causes the filter plate 7 to return to its original position, continuing to perform efficient filtration, and the filtered liquid flows out from the outlet 3.

[0038] The working principle of this device has been explained through the above embodiments. These embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
