Description

Technical Field

[0001] This utility model relates to a mesh filter, specifically a self-cleaning mesh filter. Background Technology

[0002] Mesh filters are fluid purification devices widely used in water treatment, HVAC, industrial circulating cooling water systems, and irrigation. Their core working principle involves using an internally installed metal or plastic filter screen to intercept and capture suspended particles, algae, biological slime, and other mechanical impurities in the flowing medium, thereby ensuring the normal operation of downstream equipment and the cleanliness of the water. These filters typically feature simple structure, high dirt-holding capacity, and low flow resistance, making them an indispensable protective device in fluid transport systems.

[0003] In traditional mesh filters, impurities accumulate on the filter screen surface during operation, causing the pressure difference (resistance) between the filter inlet and outlet to gradually increase. This not only increases system energy consumption and reduces flow rate, but may also lead to filter screen blockage or structural damage in severe cases. To solve this problem, the filter screen must be cleaned regularly. Existing conventional cleaning methods require interrupting system operation and manually disassembling the filter housing to remove and brush the filter screen, or using a manual rotary arm for rough cleaning. This process is not only time-consuming and labor-intensive, affecting the continuity of production, but manual cleaning is also difficult to ensure thoroughness, especially for highly adhesive impurities, which are prone to residue.

[0004] Therefore, those skilled in the art have provided a self-cleaning mesh filter to solve the problems mentioned in the background art. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this application provides a self-cleaning mesh filter, which solves the problems of conventional manual cleaning methods, which are not only time-consuming and labor-intensive, affecting the continuity of production, but also difficult to ensure thoroughness, especially for highly adhesive impurities, which are prone to leaving residues.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A self-cleaning mesh filter includes a tube body with a mesh plate inside. A feeding shell is fixedly connected to the bottom inner wall of the tube body. Several through holes are opened on the outer side of the bottom end of the feeding shell, and a through hole is opened on the outer side of the top end of the feeding shell. A rotating rod is rotatably connected to the bottom inner wall of the tube body, and a spiral plate is fixedly connected to the outer side of the rotating rod. A cover plate is provided on the top of the tube body. An annular groove is opened on the lower surface of the cover plate and a toothed ring is rotatably connected to it. A turntable is rotatably connected to the outer side of the feeding shell. Several limiting rods are provided between the turntable and the toothed ring. A brush plate is fixedly connected to one side surface of the limiting rod. Two through holes are opened inside the tube body and an inlet pipe and an outlet pipe are fixedly connected to them respectively.

[0010] Through the above technical solution, the device can continuously clean the grid plate with the brush plate during use. After the rotating rod rotates, the spiral plate can rotate, thereby conveying the impurities that fall into the feeding shell and removing the impurities from the device. This solves the problem that conventional manual cleaning methods are not only time-consuming and labor-intensive, affecting the continuity of production, but also difficult to ensure thoroughness, especially for impurities with strong adhesion, which are prone to residue.

[0011] Furthermore, a limiting ring is fixedly connected to the bottom inner wall of the tube, and the mesh plate is located between the limiting ring and the tube;

[0012] Through the above technical solution, the limiting ring plays a positioning and supporting role for the mesh plate, preventing the mesh plate from shifting during fluid impact or cleaning, ensuring stable filtration position, and guaranteeing filtration effect.

[0013] Furthermore, the inside of the cover plate and the inside of the tube are provided with several threaded holes and bolts are threadedly connected to them, and a sealing gasket is fixedly connected to the surface of the cover plate that contacts the tube.

[0014] Through the above technical solutions, the bolt connection facilitates the disassembly and installation of the cover plate and the pipe body, and makes it convenient for the later inspection and maintenance of internal components; the sealing gasket can enhance the sealing of the connection between the two, prevent fluid from leaking from the gaps, and avoid unfiltered fluid from mixing with filtered fluid and affecting the purification effect.

[0015] Furthermore, a support frame is fixedly connected to the upper surface of the cover plate, a motor is fixedly connected to the upper surface of the support frame, and the output shaft of the motor passes through the support frame and is fixedly connected to a first gear;

[0016] Through the above technical solution, the support frame provides a stable mounting carrier for the motor, and the motor, as a power source, provides power for the subsequent gear transmission and cleaning mechanism.

[0017] Furthermore, a connecting rod is fixedly connected to the lower surface of the first gear, and the end of the connecting rod away from the first gear passes through the cover plate and is fixedly connected to the second gear. The connecting rod is rotatably connected to the cover plate.

[0018] Through the above technical solution, the connecting rod achieves synchronous rotation of the first gear and the second gear, transmitting the motor power to the gear ring.

[0019] Furthermore, the second gear meshes with a gear ring, a third gear is rotatably connected to the upper surface of the feeding shell, the third gear is fixedly connected to a rotating rod, and the third gear meshes with the first gear;

[0020] Through the above technical solution, the gear meshing transmission realizes the rational distribution of power, so that the brush plate rotation cleaning and the spiral plate impurity removal are carried out simultaneously, improving the synergistic efficiency of self-cleaning and impurity removal, and ensuring that the cleaning and impurity removal process is continuous and efficient.

[0021] Furthermore, several limiting shells are fixedly connected to the upper surface of the turntable and the lower surface of the toothed ring, and the two ends of the several limiting rods are respectively located inside the several limiting shells.

[0022] Through the above technical solution, the limiting shell plays a limiting role at both ends of the limiting rod, ensuring that the limiting rod rotates synchronously and stably with the toothed ring and the turntable, avoiding the cleaning effect caused by the position displacement of the brush plate during the cleaning process, and ensuring the operational stability of the cleaning mechanism.

[0023] Furthermore, the top through hole of the feeding shell is threaded, the top of the cover plate is provided with a discharge pipe, the discharge pipe is located inside the feeding shell and threadedly connected to the feeding shell, and a pressure ring is fixedly connected to the lower surface of the cover plate, and the inside of the pressure ring is provided with a through hole adapted to the water inlet pipe.

[0024] With the above technical solution, the discharge pipe is threadedly connected to the feeding shell, which is convenient for disassembly, cleaning or replacement, ensuring that the impurity discharge channel is unobstructed, and the pressure ring can play an auxiliary role in fixing the grid plate and enhancing the connection stability.

[0025] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0026] 1. This utility model provides a self-cleaning mesh filter. Through the arrangement of a feeding shell, rotating rod, spiral plate, motor, first gear, second gear, gear ring, turntable, limiting rod, brush plate, and third gear, the device operates by rotating the first gear via the motor. The rotation of the first gear causes the second gear to rotate, which in turn drives the gear ring. The third gear then drives the rotating rod to rotate. The rotation of the gear ring causes the limiting rod to move the brush plate, allowing it to continuously clean the mesh plate. The rotation of the rotating rod causes the spiral plate to rotate, thereby conveying impurities that fall into the feeding shell and removing them from the device. This solves the problem that conventional manual cleaning methods are not only time-consuming and labor-intensive, affecting production continuity, but also difficult to ensure thoroughness, especially for highly adhesive impurities, which are prone to residue.

[0027] 2. This utility model provides a self-cleaning mesh filter. Through the setting of cover plate, limiting shell, limiting rod, discharge pipe, limiting ring and pressure ring, after the device has been used for a long time, only the cover plate needs to be removed to remove the fixing of brush plate and mesh plate. The brush plate and mesh plate can be quickly and easily removed and replaced with new brush plate and mesh plate. This solves the problem that some filters with self-cleaning function have a more complicated internal structure and cannot quickly and easily replace the filter mechanism and cleaning mechanism.

[0039] Please see Figure 3 , Figure 4 , Figure 5In this embodiment, a self-cleaning mesh filter is provided. A limiting ring 19 is fixedly connected to the bottom inner wall of the tube body 1. The mesh plate 2 is located between the limiting ring 19 and the tube body 1. Several threaded holes are opened inside the cover plate 8 and the tube body 1, and bolts are threadedly connected to them. A sealing gasket is fixedly connected to the surface of the cover plate 8 in contact with the tube body 1. Several limiting shells 14 are fixedly connected to the upper surface of the turntable 13 and the lower surface of the toothed ring 12.

[0040] This embodiment of a self-cleaning mesh filter involves a feeding housing 3, a rotating rod 4, a spiral plate 5, a motor 7, a first gear 9, a second gear 11, a gear ring 12, a turntable 13, a limiting rod 15, a brush plate 16, and a third gear 17. During operation, the motor 7 drives the first gear 9 to rotate, which in turn causes the second gear 11 to rotate the gear ring 12. The third gear 17 then drives the rotating rod 4 to rotate. The rotation of the gear ring 12 causes the limiting rod 15 to move the brush plate 16, allowing it to continuously clean the mesh plate 2. The rotation of the rotating rod 4 causes the spiral plate 5 to rotate, thereby conveying impurities that fall into the feeding housing 3. This device removes impurities, solving the problem that conventional manual cleaning methods are not only time-consuming and labor-intensive, affecting production continuity, but also difficult to ensure thoroughness, especially for highly adhesive impurities, which are prone to residue. Through the design of cover plate 8, limiting shell 14, limiting rod 15, discharge pipe 18, limiting ring 19, and pressure ring 20, after a long period of use, the device can be easily removed by simply disassembling cover plate 8 to remove the fixing of brush plate 16 and mesh plate 2, and the brush plate 16 and mesh plate 2 can be quickly and easily removed and replaced with new brush plate 16 and mesh plate 2. This solves the problem that some self-cleaning filters have complex internal structures, making it difficult to quickly and easily replace the filter mechanism and cleaning mechanism.

[0041] The working principle of the above embodiment is as follows: In use, the inlet pipe 21 and the outlet pipe 22 are connected to the external pipeline. After connection, the water source enters the interior of the pipe body 1 through the inlet pipe 21 and falls into the interior of the mesh plate 2. After the water source is inside the mesh plate 2, it flows into the interior of the outlet pipe 22 through the mesh holes inside the mesh plate 2 and flows to the outside. Impurities in the water source are intercepted by the mesh plate 2 and remain inside the mesh plate 2. After too many impurities are intercepted, the motor 7 is started. The output shaft of the motor 7 drives the first gear The first gear 9 rotates, and after the first gear 9 rotates, it causes the second gear 11 to rotate via the connecting rod 10. The rotation of the second gear 11 causes the gear ring 12 to rotate. After the gear ring 12 rotates, it drives the limiting rod 15 to move via the limiting shell 14. After the limiting rod 15 moves, the brush plate 16 contacts the mesh plate 2 and cleans the mesh plate 2. The cleaned impurities fall to the bottom of the mesh plate 2 and enter the interior of the feeding shell 3 through the bottom through hole. At this time, the first gear 9 causes the third gear 17 to rotate. After the third gear 17 rotates, it causes the rotating rod 4 to drive the screw... The rotating plate 5 conveys impurities inside the feeding shell 3, moving them to the top of the feeding shell 3 and discharging them to the outside through the discharge pipe 18. When the device has been used for an extended period, causing severe wear on the mesh plate 2 and brush plate 16, rendering them ineffective, the user can remove the bolts inside the cover plate 8, then rotate the discharge pipe 18 to disconnect it from the threaded connection to the feeding shell 3. Afterward, the cover plate 8 can be moved, detaching it from the pipe body 1. Once the cover plate 8 is removed, the user can... Remove the old mesh plate 2 and the old limiting rod 15. After removal, the user places the new mesh plate 2 between the tube body 1 and the limiting ring 19 to fix the mesh plate 2. Then, place the new limiting rod 15 inside the limiting shell 14 to initially fix the limiting rod 15. After that, the cover plate 8 can be installed again so that the pressure ring 20 contacts the mesh plate 2 to limit the top of the mesh plate 2. The limiting shell 14 at the bottom of the toothed ring 12 contacts the limiting rod 15 to fix the limiting rod 15.
