Description

Technical Field

[0001] This utility model relates to the field of circulating water filter technology, specifically a circulating water filter. Background Technology

[0002] A circulating water filter is a device that uses a filter screen to directly intercept impurities in water, remove suspended solids and particulate matter, reduce turbidity, purify water quality, and reduce the generation of system dirt, algae, rust, etc., so as to purify water for reuse.

[0003] Patent document CN222930453U discloses a circulating water filter, including a cylinder, a filtration mechanism, and a drive anti-clogging mechanism. The cylinder has a sealing cap at the top and a bottom cover fixedly connected to its lower end via a mounting flange. A rotating groove is formed on the lower side of the inner arc surface of the cylinder. The filtration mechanism includes a filter screen mounting frame, a reinforcing rod, a coarse filter screen frame, a coarse filter screen, and a fine filter screen. The filter screen mounting frame is rotatably connected to the inside of the rotating groove. A fine filter screen is fixedly connected between the upper and lower inner walls of the filter screen mounting frame. A reinforcing rod is fixedly connected between the upper and lower inner walls of the filter screen mounting frame, and the outer arc surface of the reinforcing rod is fixedly connected to the fine filter screen. A coarse filter screen is fixedly connected to the upper end of the filter screen mounting frame via the coarse filter screen frame. The drive anti-clogging mechanism is located inside the cylinder and is rotatably connected to the bottom cover. This circulating water filter allows for very simple sewage discharge and will not affect subsequent water circulation operations.

[0004] Although the application document states that the motor rotates at low speed, thereby driving the rotating rod to reduce the rotation speed, and the upper scraper slowly scrapes the upper inner wall of the cylinder, it can only perform axial rotation cleaning during use. The vertical surface of the fine filter screen will be clogged with dirt, resulting in cleaning dead corners.

[0005] Therefore, a circulating water filter is proposed to solve the problems mentioned above. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a circulating water filter that solves the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: including a cylinder, wherein a cleaning mechanism is assembled inside the cylinder;

[0008] The cleaning mechanism includes a chute formed on the arc-shaped surface of the inner wall of the cylinder. A slider is slidably connected to the inner wall of the chute, and a connecting rod is fixedly connected to the side of the slider. A filter cylinder is fixedly connected to the side of the connecting rod. A first turntable is rotatably connected to the bottom of the inner wall of the cylinder via a bearing. A cleaning rod is fixedly connected to the top of the first turntable. A second turntable is rotatably connected to the bottom of the inner wall of the cylinder via a bearing. A limit rod is fixedly connected to the top of the second turntable. A limit groove is formed at the top of the filter cylinder. A slider is fixedly connected to the side of the inner wall of the limit groove. The filter cylinder is slidably connected to the outer wall of the limit rod. A drive assembly for driving the limit rod to rotate is assembled inside the cylinder.

[0009] Preferably, the drive assembly includes a motor, which is fixedly connected to the top of the cylinder. A rotating rod is rotatably connected to the top of the inner wall of the cylinder via a bearing. The rotating rod moves through the cylinder, and its extension end extends toward the top of the cylinder. The output end of the motor is fixedly connected to the extension end of the rotating rod. A connecting shaft is fixedly connected to the bottom of the rotating rod, and the bottom of the connecting shaft is fixedly connected to the top of the limiting rod.

[0010] Preferably, the top of the filter cartridge has a sliding groove for the cleaning rod to slide.

[0011] Preferably, the outer wall of the limiting rod is fixedly connected to two T-shaped rods in a mirror image.

[0012] Preferably, the slider has rounded corners on its side to improve the smoothness of its sliding.

[0013] Preferably, the slide bar has a rounded corner on its side to improve the smoothness of the slide bar sliding on the inner wall of the T-shaped bar.

[0014] Preferably, a water inlet is fixedly connected to the side of the cylinder, a water outlet is fixedly connected to the side of the cylinder, and a base is fixedly connected to the bottom of the cylinder.

[0015] Compared with the prior art, this utility model provides a circulating water filter with the following beneficial effects: During the filtration process, when the motor drives the limiting rod to rotate, the T-shaped rod drives the filter cylinder to rotate axially synchronously, so that the water flow generates centrifugal force to achieve preliminary impurity separation; at the same time, the slider slides along the high and low trajectory of the slide groove, forcing the filter cylinder to move up and down continuously during rotation. At this time, the cleaning rod fixed at the bottom continuously scrapes the inner wall of the filter cylinder, thoroughly breaking down the hardened dirt attached to the surface of the filter screen, significantly improving filtration efficiency and continuity, reducing the need for manual intervention, and reducing the risk of filter screen clogging and maintenance frequency, ensuring stable operation of the system under high turbidity or viscous dirt conditions.
