Description

Technical Field

[0001] This utility model relates to the technical field of flow guide filter precision adjustment tools, and in particular to a flow guide filter with adjustable filtration precision. Background Technology

[0002] As a key component in fluid transport systems, flow guide filters are widely used in industrial fields such as chemical, petroleum, water treatment, and food and beverage. Their core function is to intercept solid impurities in fluids through filter screens, ensuring the normal operation of downstream equipment and product quality. For example, in chemical production, flow guide filters can prevent impurities such as welding slag and rust in pipelines from clogging valves or pumps; in wastewater treatment systems, they can effectively remove suspended solids from water, providing a guarantee for subsequent treatment processes. Most existing filters use a single-size filter screen. Replacing the filter screen with one of different precision requires stopping the machine for disassembly, which is not only time-consuming and labor-intensive, but may also lead to fluid leakage or system contamination, and cannot meet the real-time adjustment requirements under dynamic operating conditions. In addition, the filter screen is prone to clogging in fluids with high impurity content. Existing devices mostly use insertion-type installation for the filter screen, which involves many parts, making filter screen disassembly cumbersome. Therefore, the above problems need to be solved.

A filtration mechanism is installed inside the guide chamber 3. The sealing mechanism includes a sealing bearing 5 sleeved on the upper end of the rotating rod 4, which helps prevent leakage when adjusting the filter screen precision. Water; the sealed bearing 5 passes through the middle of the flange 2. The adjustment mechanism includes a second turntable 7 rotatably mounted on the top surface of the flange 2 and a third gear 15 mounted on the bottom end of the rotating rod 4. The second turntable 7 facilitates the rotation of the rotating rod 4 by cooperating with the first turntable 6. The sealed bearing 5 is located in the middle of the second turntable 7. Three telescopic rods 8 are equidistantly installed on the top surface of the second turntable 7. The telescopic rods 8 facilitate the adjustment of the height of the third gear 15 to cooperate with the meshing transmission of the first gear 13 and the second gear 14. The telescopic rod 8 is equipped with the first turntable 6 at its telescopic end. A valve 9 is installed directly above the first turntable 6. The valve 9 facilitates the adjustment of the filter screen size. The top end of the rotating rod 4 is connected to the first turntable 6. A cylindrical placement groove is opened inside the flow guide chamber 3.

[0015] In this utility model, the filtration mechanism is located in the placement groove, which is connected to the valve pipe. The guide chamber 3 has an inlet at its rear end and a drain at its front end, which facilitates water flow guidance. The adjustment mechanism includes a filter cylinder 10 placed in the placement groove, which facilitates the installation of a second filter screen 11 and a third filter screen 12. A first filter screen is located at the front end of the filter cylinder 10, and the second and third filter screens 11 and 12 are installed inside the filter cylinder 10. The second and third filter screens 11 and 12 allow for easy adjustment of the filter hole size by rotation. The second and third filter screens 11 and 12... A first gear 13 and a second gear 14 are respectively installed on the screen 12. The first gear 13 and the second gear 14 facilitate the rotation of the second filter screen 11 and the third filter screen 12. Both the first gear 13 and the second gear 14 can mesh with the third gear 15. A first rotating shaft is fixedly connected to the middle of the first gear 13.

The bottom end of the second rotating shaft is rotatably installed in the bottom of the filter cylinder 10, and the top end of the second rotating shaft is fixedly connected to the second gear 14.

[0016] Working principle: When this utility model is used, when water flows through, the water enters the guide chamber 3 through the inlet, and then passes through the third filter screen 12, the second filter screen 11 and the first filter screen before being discharged through the drain outlet. Depending on the water quality, the valve 9 is turned, which drives the first turntable 6 to rotate. The first turntable 6 drives the rotating rod 4 to rotate, and the rotating rod 4 drives the second gear 14 to rotate through the third gear 15 at the bottom. By rotating the third filter screen 12, the size of the filter holes is changed. Then, the valve 9 is pressed down, causing the third gear 15 to disengage from the second gear 14 and engage with the first gear 13. Then, the second filter screen 11 is rotated to change the size of the filter holes, thereby adjusting the filtration accuracy according to the water quality. During this process, the telescopic rod 8 can help the rotating rod 4 to return to its original position, and the sealed bearing 5 can prevent water leakage at the contact part between the flange 2 and the rotating rod 4. When it is necessary to clean the filter screen, simply remove the flange 2 and take out the filter cylinder 10.
