Description

Technical Field

[0001] This invention relates to the field of filter technology, and in particular to a Y-type ribbed filter. Background Technology

[0002] Y-type filters are an indispensable filtration device in pipeline systems for conveying media. They are typically installed at the inlet of pressure reducing valves, pressure relief valves, level control valves, or other equipment to remove impurities from the media, protecting the valves and equipment. Y-type filters feature advanced structure, low resistance, and convenient drainage. Suitable media include water, oil, and gas. Generally, the mesh size is 18-30 mesh for water, 10-100 mesh for air, and 100-480 mesh for oil. Basket filters mainly consist of connecting pipes, main pipes, filter baskets, flanges, flange covers, and fasteners. When liquid enters the filter basket through the main pipe, solid impurity particles are trapped inside, while clean fluid passes through the basket and exits through the filter outlet.

[0003] In the existing technology, after a period of use, impurities tend to stick to one side of the filter basket at the liquid outlet, affecting the normal filtration effect of the Y-type filter. This problem urgently needs to be solved. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a Y-type ribbed filter to solve the above problems.

[0005] The technical solution of this invention is implemented as follows: A Y-type ribbed filter includes a valve body, the valve body comprising:

[0006] Inlet pipe body;

[0007] Outlet pipe body;

[0008] The filter tube is fixedly connected between the inlet pipe and the outlet pipe, and a valve cover is threaded to the end of the filter tube away from the inlet pipe and the outlet pipe.

[0009] The outer filter element is located inside the filter tube.

[0010] The inner filter cartridge is located inside the outer filter cartridge.

[0011] The outer wall of the inner filter cartridge abuts against the inner wall of the outer filter cartridge, and a transmission mechanism for driving the inner and outer filter cartridges to rotate relative to each other is connected to the side of the valve cover facing the inner filter cartridge.

[0012] By adopting the above technical solution, the transmission mechanism that works in conjunction with the outer filter cartridge and the inner filter cartridge can automatically switch the relative positions of the liquid outlets of the inner and outer filter cartridges when they are blocked. No manual operation is required, the structure is simple, and it effectively extends the service life of the inner and outer filter cartridges and improves the filtration effect.

[0013] The present invention is further configured such that: the transmission mechanism includes:

[0014] Connecting shaft A is located in the middle of the upper part of the valve cover, and a rotating cavity is formed inside the hollow connecting shaft A;

[0015] Connecting shaft B is rotatably and sealed within the rotating cavity;

[0016] Turntable A is fixedly connected to the upper end of connecting shaft A;

[0017] Turntable B is located above turntable A;

[0018] The driver box is located above turntable B;

[0019] The rotating disk A is snapped into the outer filter cartridge, one end of the connecting shaft B passes through the upper surface of the rotating disk A and is fixedly connected to the rotating disk B, the rotating disk B is snapped into the inner filter cartridge, and there is a gap between the rotating disk A and the rotating disk B.

[0020] By adopting the above technical solution, the drive box is driven by water flow to rotate the connecting shaft A and the connecting shaft B relative to each other. At this time, the turntable A and the turntable B drive the outer filter cartridge and the inner filter cartridge to rotate relative to each other, which facilitates the removal of impurities attached to the filter cartridge pore wall and has a good effect.

[0021] The present invention is further configured to include:

[0022] Several insert blocks A are circumferentially fixed to the outside of turntable A;

[0023] Several insert blocks B are circumferentially fixed to the outside of turntable B;

[0024] Several slots A are provided at the lower end of the outer filter cartridge;

[0025] Several slots B are located at the lower end of the inner filter cartridge;

[0026] Among them, several plug blocks A correspond one-to-one with several slots A, and several plug blocks B correspond one-to-one with several slots B.

[0027] By adopting the above technical solution, the transmission mechanism is fixed by inserting the plug into the slot on the filter cartridge, which results in a firm connection, simple structure, and convenient assembly and disassembly.

[0028] The present invention is further configured such that: the transmission mechanism also includes:

[0029] A sealing housing is fixedly connected to the upper part of the valve cover;

[0030] The inner shell is cylindrical and is rotatably connected to the upper end of the sealed shell.

[0031] The reversing mechanism is located inside the inner shell;

[0032] Among them, the end of the connecting shaft A away from the turntable A passes through the sealing housing and is fixedly connected to the end of the inner shell away from the valve cover. The end of the connecting shaft B away from the turntable B passes through the inner shell and extends into the inner shell, and is connected to the connecting shaft B through the reversing mechanism.

[0033] By adopting the above technical solution, the axial drive of shaft B can be switched to an axial drive force opposite to that of shaft B and transmitted to shaft A through a reversing mechanism. This eliminates the need for manual operation and yields good results.

[0034] The present invention is further configured such that: the reversing mechanism includes:

[0035] Connecting shaft C is fixedly connected to the inner shell on one side adjacent to the valve cover;

[0036] Bevel gear A is keyed to the end of connecting shaft C;

[0037] Connecting shaft D;

[0038] Connecting shaft E and connecting shaft D are rotatably connected to the inner two side walls of the inner shell relative to connecting shaft E;

[0039] Bevel gear B;

[0040] Bevel gear C and bevel gear B are keyed to the ends of connecting shaft D and connecting shaft E, respectively;

[0041] Connecting shaft F is rotatably connected to the inner shell on the side away from connecting shaft C;

[0042] Bevel gear D is keyed to the end of connecting shaft F.

[0043] Among them, connecting shaft D is coaxial with connecting shaft E, the extension line of the axis of connecting shaft D is perpendicular to the extension line of the axis of connecting shaft C, the lower ends of bevel gear B and bevel gear C respectively mesh with bevel gear A, the extension line of the axis of connecting shaft F coincides with the extension line of the axis of connecting shaft C, and the upper ends of bevel gear B and bevel gear C respectively mesh with bevel gear D.

[0044] By adopting the above technical solution, when the drive box drives the connecting shaft B to rotate counterclockwise, the connecting shaft B drives the connecting shaft F and the bevel gear D connected to the connecting shaft F to rotate synchronously. At this time, the bevel gears B and C, which are meshed with the bevel gear D, rotate in opposite directions. Since the bevel gears B and C are meshed with the bevel gear A, the bevel gear A drives the inner shell connected to the connecting shaft C to rotate clockwise synchronously. When the inner shell drives the outer filter cartridge to rotate clockwise through the connecting shaft A and the turntable A, the turntable B drives the inner filter cartridge to rotate clockwise through the action of the connecting shaft B.

[0045] The present invention is further configured such that: the end of the connecting shaft B away from the turntable B passes through the inner shell and is fixedly connected to the connecting shaft F by bolts, and the connecting shaft B and the connecting shaft F are coaxial.

[0046] By adopting the above technical solution, the connection is firm and the structure is stable.

[0047] The present invention is further configured such that: the driver box includes:

[0048] The box is located above turntable B;

[0049] Connecting shaft G is rotatably connected to the middle part of the box body;

[0050] Several blades are welded to the outside of the connecting shaft G;

[0051] A spring is fixedly connected between the box body and the upper surface of turntable B;

[0052] The outer wall of the box abuts against the inner wall of the inner filter cartridge. Several water outlet holes are opened around the outer side of the box. A plug is fixedly connected to the upper end of the turntable B. A water inlet hole A is added to the outer side of the upper end of the plug. One end of the connecting shaft G passes through the box and is fixedly connected to the middle of the upper end of the turntable B.

[0053] By adopting the above technical solution, when the side of the inner and outer filter cartridges that is filtering becomes blocked, the water pressure inside the inner filter cartridge increases. When the water pressure exceeds the elastic force of the spring, the box is pressed against the turntable B. At this time, the water in the inner filter cartridge enters the box through the inlet hole A, which drives the impeller to rotate the connecting shaft G and then flows to the outlet pipe through the outlet hole. After the connecting shaft G rotates, it drives the inner and outer filter cartridges to switch their filtration positions through the transmission mechanism, which extends the service life. After switching, the water pressure returns to a stable state, and the box is reset by the elastic force of the spring, resulting in good performance.

[0054] The present invention is further configured such that: a water inlet hole B communicating with a water inlet hole A is provided in the lower part of the plug-in post, and an opening for the plug-in post to extend is provided at the upper end of the box body.

[0055] By adopting the above technical solution, when the housing is pressed against the turntable B, since the insertion post is fixed, it extends out of the upper surface of the housing through the opening. Water enters the insertion post through the water inlet A and then exits through the water inlet B to the impact blade. After the water pressure stabilizes, the housing returns to its original position, and the upper end of the insertion post repositions back into the opening to form a seal. This prevents water from entering the housing and driving the connecting shaft to rotate, thus preventing frequent displacement of the inner and outer filter cartridges, which could cause wear and noise.
