Description

Technical Field

[0001] This utility model relates to the field of cyclone filter technology, and in particular to an anti-clogging high-speed dual cyclone filter. Background Technology

[0002] A dual-cyclone filter is a device used for fluid filtration, widely applied in the purification of liquids or gases. Its working principle is based on the cyclone effect, achieving particulate separation through the specific rotational motion of the fluid. The dual-cyclone filter utilizes the synergistic effect of two cyclone channels to achieve higher filtration efficiency, making it suitable for various fields such as water treatment, air purification, and petrochemicals.

[0003] In the prior art, Chinese patent application number 202022721781.7 discloses an easy-to-maintain, high-efficiency dual-cyclone filter. The dual-cyclone filter includes a cylindrical body with an inlet near the top and an outlet at the top. The inlet and outlet connect to a cyclone channel inside the cylinder. A cylindrical filter screen is positioned below the outlet inside the cylinder and rests on a filter screen frame. The filter screen frame has a lifting rod at its center that passes through the filter screen, and the lifting rod is sealed to the filter screen. The filter screen frame is supported on a flange on the inner wall of the cylinder. A pressure-increasing bag is arranged around the periphery of the cylindrical filter screen, and the pressure-increasing bag has a pressure-increasing port. A cap is connected to the top of the cylindrical body. This dual-cyclone filter facilitates cleaning, maintenance, and replacement of the filter screen.

[0004] However, the above-mentioned technical solutions involve fixing the end cap and the cylinder with bolts, which requires the use of matching tools to remove and install the bolts when maintaining the filter screen, which has significant limitations and reduces the convenience of maintenance. At the same time, the method of fixing the filter screen and the cylinder by pressurizing the expansion bag only relies on friction to fix it. Since the water flows from bottom to top when it enters the cylinder through the inlet pipe and is discharged through the outlet pipe, the impact force of the water flow may cause the filter screen to loosen, thereby affecting the performance. Therefore, this application proposes an anti-clogging high-speed dual cyclone filter to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of existing technologies where the end cap and cylinder are fixed with bolts, requiring the use of matching tools to remove and install the bolts when maintaining the filter screen, which has significant limitations and reduces the convenience of maintenance. At the same time, the method of fixing the filter screen and cylinder by inflating the expansion bag relies solely on friction for fixation. Since the water flows from bottom to top when it enters the cylinder through the inlet pipe and exits through the outlet pipe, the impact force of the water flow may loosen the filter screen, thus affecting the performance. Therefore, this utility model proposes an anti-clogging high-speed dual vortex filter.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A clog-resistant high-speed dual-cyclone filter includes a support frame, and the filter further includes:

[0008] A dual-cyclone filter cylinder is fixedly mounted on a bracket, and a discharge pipe is fixedly connected to the bottom end of the dual-cyclone filter cylinder.

[0009] The water outlet pipe is fixedly connected to the front side of the double vortex filter cylinder;

[0010] The water inlet pipe is fixedly connected to the rear side of the dual vortex filter cylinder;

[0011] The filter assembly includes: an annular support block, a filter screen, and a pressurized expansion bag. The annular support block is fixedly installed on the inner wall of the double cyclone filter cylinder, and the pressurized expansion bag is fixedly sleeved on the filter screen. The outer side of the pressurized expansion bag is in contact with the inner wall of the double cyclone filter cylinder, and the bottom of the filter screen is in contact with the top of the annular support block.

[0012] End cap, which is placed at the top of the dual cyclone filter cylinder;

[0013] A base plate, the top of which is fixedly mounted on the bottom end of the bracket;

[0014] A switching mechanism is provided on the top of the base plate and cooperates with the end cap.

[0015] As a preferred embodiment of this utility model, a discharge valve is fixedly installed on the discharge pipe.

[0016] As a preferred embodiment of this utility model, a sealing ring is fixedly installed at the bottom of the end cap, and the bottom of the sealing ring is in contact with the top of the double cyclone filter cylinder.

[0017] As a preferred embodiment of this utility model, four pressure rods are fixedly installed inside the end cap, and the bottom ends of the four pressure rods are in contact with the top of the filter screen.

[0018] As a preferred embodiment of this utility model, the switching mechanism includes a U-shaped frame, a motor, a double-axis lead screw, two nuts, and two transmission rods. The bottom end of the U-shaped frame is fixedly installed on the top of the base plate, the motor is fixedly installed on the right side of the U-shaped frame, the left end of the double-axis lead screw is rotatably connected to the left inner wall of the U-shaped frame, the right end of the double-axis lead screw is fixedly installed on the output shaft of the motor, both nuts are threaded onto the double-axis lead screw, the top end of the transmission rod is rotatably connected to the bottom of the corresponding nut, and the bottom ends of both transmission rods are rotatably connected to the top of the end cap.

[0019] As a preferred embodiment of this utility model, slide rods are fixedly installed on both the left and right sides of the end cap, and slide grooves are provided on both the left and right inner walls of the U-shaped frame, with the ends of the two slide rods slidably connected in the two slide grooves respectively.

[0020] Beneficial effects:

[0021] 1. By starting the motor, the dual-axis lead screw can be driven to rotate. Then, through the threaded connection between the dual-axis lead screw and the two nuts, the two nuts can be driven to move away from each other. This will cause the top ends of the two transmission rods to move away from each other. At this time, the bottom ends of the two transmission rods can pull the end cap upward, thus realizing the disassembly of the end cap and the double cyclone filter body. This facilitates the disassembly and maintenance of the filter screen. By using the reverse operation of the above structure, a stable installation between the end cap and the double cyclone filter body can be achieved. It is easy to operate and highly practical.

[0022] 2. By setting a pressure bar, after the end cap and the double cyclone filter cylinder are closed, the pressure bar can press and fix the filter screen, which can prevent the filter screen and pressurized expansion bag from loosening between the filter screen and the inner wall of the double cyclone filter cylinder due to the impact of water flow, and ensure the installation stability of the filter screen and pressurized expansion bag.

[0023] This utility model achieves quick assembly and disassembly between the end cap and the double vortex filter cylinder through a simple structure, without the need for matching tools, thus minimizing limitations and improving the convenience of filter screen maintenance. At the same time, the pressure rod clamps and fixes the filter screen, preventing the filter screen from loosening due to the impact of water flow, ensuring the effectiveness of use, and making it highly practical.

[0034] Water inlet pipe 6 is fixedly connected to the rear side of the double vortex filter cylinder 2;

[0035] The filter assembly includes an annular support block 7, a filter screen 8, and a pressurized expansion bag 9. The annular support block 7 is fixedly installed on the inner wall of the double cyclone filter cylinder 2. The pressurized expansion bag 9 is fixedly sleeved on the filter screen 8. The outer side of the pressurized expansion bag 9 is in contact with the inner wall of the double cyclone filter cylinder 2, and the bottom of the filter screen 8 is in contact with the top of the annular support block 7.

[0036] End cap 10 is placed at the top of the double cyclone filter cylinder 2;

[0037] The base plate 11 is fixedly installed at the bottom end of the bracket 1.

[0038] The switching mechanism is located on the top of the base plate 11 and cooperates with the end cap 10.

[0039] With the above structure, by setting the end cap 10 and the double vortex filter cylinder 2 as separate parts, and separating them by lifting up and down, it is easy to maintain the filter screen 8.

[0040] As a preferred embodiment of this utility model, a discharge valve 4 is fixedly installed on the discharge pipe 3. By setting the discharge valve 4, it is easy to open and close the discharge pipe 3, so as to facilitate the discharge of impurities in the sewage into the double cyclone filter cylinder 2.

[0041] As a preferred embodiment of this utility model, a sealing ring 19 is fixedly installed at the bottom of the end cap 10. The bottom of the sealing ring 19 is in contact with the top of the double cyclone filter cylinder 2. By setting the sealing ring 19, the double cyclone filter cylinder 2 and the end cap 10 can be effectively sealed.

[0042] As a preferred embodiment of this utility model, four pressure rods 20 are fixedly installed inside the end cap 10. The bottom ends of the four pressure rods 20 are in contact with the top of the filter screen 8. By setting the pressure rods 20, after the end cap 10 and the double vortex filter cylinder 2 are closed, the pressure rods 20 can press and fix the filter screen 8, which can prevent the filter screen 8 and the pressurized expansion bag 9 from loosening between the filter screen 8 and the inner wall of the double vortex filter cylinder 2 due to the impact of the water flow, and ensure the installation stability of the filter screen 8 and the pressurized expansion bag 9.

[0043] In a preferred embodiment of this utility model, the switching mechanism includes a U-shaped frame 12, a motor 13, a dual-axis lead screw 14, two nuts 15, and two transmission rods 16. The bottom end of the U-shaped frame 12 is fixedly installed on the top of the base plate 11. The motor 13 is fixedly installed on the right side of the U-shaped frame 12. The left end of the dual-axis lead screw 14 is rotatably connected to the left inner wall of the U-shaped frame 12, and the right end of the dual-axis lead screw 14 is fixedly installed on the output shaft of the motor 13. Both nuts 15 are threaded onto the dual-axis lead screw 14. The top end of each transmission rod 16 is rotatably connected to the bottom of the corresponding nut 15, and the bottom ends of both transmission rods 16 are rotatably connected to the top of the end cap 10. The motor 13 drives the dual-axis lead screw 14 to rotate. Through the threaded connection between the dual-axis lead screw 14 and the two nuts 15, the two nuts 15 are moved away from each other. This causes the top ends of the two transmission rods 16 to move away from each other. At this time, the bottom ends of the two transmission rods 16 can pull the end cap 10 upward. This allows for the disassembly of the end cap 10 from the double cyclone filter cylinder 2, facilitating the disassembly and maintenance of the filter screen 8. By reversing the above structure, a stable installation between the end cap 10 and the double cyclone filter cylinder 2 can be achieved. The operation is convenient and highly practical.

The ends of the two slide rods 17 that are far apart from each other are slidably connected in the two slide grooves 18 respectively. Through the sliding limit cooperation between the slide rods 17 and the slide grooves 18, the end cap 10 can be stably supported for up and down movement.

[0045] It should be noted that the specific model of discharge valve 4 and motor 13 to be used shall be selected by those skilled in the art. Furthermore, the discharge valve 4 and motor 13 mentioned above are all existing technologies and will not be elaborated upon in this solution.

[0046] The dual vortex filter cylinder 2 adopts existing technology and can be directly used with the main structure of the device of the patent with application number 202022721781.7. The dual vortex structure therein will not be described in detail.

[0047] The working principle of this utility model is as follows: In use, first connect the discharge valve 4 and motor 13 to an external power source. Then, starting the motor 13 drives the dual-axis lead screw 14 to rotate. Through the threaded connection between the dual-axis lead screw 14 and the two nuts 15, the two nuts 15 are moved away from each other. This causes the top ends of the two transmission rods 16 to move away from each other. At this point, the bottom ends of the two transmission rods 16 pull the end cap 10 upwards, thus enabling the disassembly of the end cap 10 from the double-cyclone filter cylinder 2. This facilitates the disassembly and maintenance of the filter screen 8. Through the reverse operation of the above structure, a stable installation between the end cap 10 and the double vortex filter cylinder 2 can be achieved. The operation is convenient and highly practical. In addition, by setting the pressure rod 20, after the end cap 10 and the double vortex filter cylinder 2 are closed, the pressure rod 20 can press and fix the filter screen 8, which can prevent the impact force of the water flow from causing the filter screen 8 and the pressurized expansion bag 9 to loosen between them and the inner wall of the double vortex filter cylinder 2, thus ensuring the installation stability of the filter screen 8 and the pressurized expansion bag 9.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
