Its main function is to protect the engine to operate normally and well. By circulating in the engine water tank, it plays roles such as antifreeze, anti-boiling, rust prevention and corrosion prevention.

[0003] The Chinese utility model patent with the authorization announcement number of CN217188158U discloses an antifreeze filtration device. The antifreeze filtration device is provided with a diversion plate that can swing back and forth, so that the antifreeze can fall to the first filtration layer more evenly, and will not always impact the same position of the first filtration layer. At the same time, the diversion plate can slow down the impact force when the antifreeze falls to the first filtration layer, improving the filtration effect and production efficiency; however, when filtering the antifreeze, it mainly filters through the filtration layer. After long-term use, solid impurities in the antifreeze will accumulate on the filtration layer, causing blockage of the filtration layer, and regular maintenance and cleaning are required, which affects the service life of the filtration device.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Example 1

[0025] The utility model provides an antifreeze filtering device. As Figures 1-4 shown, the antifreeze filtering device includes a filtering cylinder 1, a liquid injection pipe 11 penetrating through the top surface of the filtering cylinder 1, and drain pipes 12 symmetrically arranged on the outer wall of the bottom end of the filtering cylinder 1. A filter screen plate 2 is arranged on the inner side wall of the filtering cylinder 1. A support rod 13 is fixedly installed at the inner top wall of the filtering cylinder 1 at a position communicated with the liquid injection pipe 11. A liquid guide plate 4 is arranged at one end of the support rod 13 away from the filtering cylinder 1. A connecting mechanism 42 is arranged between the support rod 13 and the liquid guide plate 4;

[0026] A driving motor 3 is fixedly installed on the bottom surface of the filtering cylinder 1. A driving rod 31 is rotatably installed on the inner bottom wall of the filtering cylinder 1. The bottom end of the driving rod 31 passes through the filtering cylinder 1 and is fixedly connected to the output shaft of the driving motor 3. The top end of the driving rod 31 passes through the filter screen plate 2. A cleaning mechanism 32 is arranged on the inner side wall of the filtering cylinder 1 and the driving rod 31.

[0027] During use, the antifreeze can enter the interior of the filtering cylinder 1 through the liquid injection pipe 11. When the antifreeze enters the filtering cylinder 1, it can first come into contact with the liquid guide plate 4 and flow along the liquid guide plate 4, so that the antifreeze can be dispersed and flow onto the filter screen plate 2 and be filtered by the filter screen plate 2. The filter residue in the antifreeze can remain on the filter screen plate 2. The filtered antifreeze can enter the bottom of the filtering cylinder 1 and be discharged through the drain pipe 12 for continued use. During the filtering process of the antifreeze, the driving motor 3 can be turned on to drive the driving rod 31 to rotate. During the rotation of the driving rod 31, the cleaning mechanism 32 can be used to clean the filter screen plate 2 to avoid the accumulation of filter residue.

[0028] Specifically, the cleaning mechanism 32 includes an aggregate frame 321 fixedly installed on the inner side wall of the filtering cylinder 1 and adapted to the filter screen plate 2, and a cleaning brush plate 322 fixedly installed on the driving rod 31 at a position above the filter screen plate 2 and adapted to the filter screen plate 2. A plurality of uniformly distributed through holes are formed in the inner bottom wall of the aggregate frame 321. The outer diameter of the filter screen plate 2 is the same as the inner diameter of the aggregate frame 321. During the rotation of the driving rod 31, the cleaning brush plate 322 can be driven to rotate. The bristles at the bottom of the cleaning brush plate 322 can clean the mesh holes on the filter screen plate 2. As the cleaning brush plate 322 rotates, the filter residue cleaned out can enter the aggregate frame 321 under the action of centrifugal force for collection. At the same time, the antifreeze entering the aggregate frame 321 can pass through the through holes in the inner bottom wall of the aggregate frame 321 for normal filtering.

[0029] More specifically, the connecting mechanism 42 includes a mounting hole 421 formed at the tip of the liquid guide plate 4, a connecting ball groove 422 formed on the inner side wall of the mounting hole 421, and a connecting ball head 423 fixedly installed at one end of the support rod 13 away from the filter cartridge 1 and movably connected to the connecting ball groove 422; the liquid guide plate 4 is connected to the support rod 13 through the cooperation of the connecting ball groove 422 and the connecting ball head 423. Therefore, under the impact of the antifreeze, the liquid guide plate 4 can move, so that the antifreeze can flow to a wider range on the filter screen plate 2.

[0030] Further, a plurality of liquid guide grooves 41 are formed on the top surface of the liquid guide plate 4 and are distributed in an annular array; when the antifreeze flows onto the liquid guide plate 4, it can enter the liquid guide grooves 41 and flow, making the flow of the antifreeze more orderly.

[0031] Embodiment 2

[0032] Different from Embodiment 1, a driving mechanism 5 is provided between the driving rod 31 and the liquid guide plate 4. The driving mechanism 5 includes a connecting rod 51 fixedly installed at the top end of the driving rod 31, a driving ball head 52 fixedly installed at one end of the connecting rod 51 away from the driving rod 31, and a plurality of fixedly installed at the bottom edge position of the liquid guide plate 4 and corresponding to the driving ball head 52 and distributed in an annular array of fixed hemispherical heads 53.

[0033] During use, when the driving motor 3 drives the driving rod 31 to rotate, it can synchronously drive the connecting rod 51 and the driving ball head 52 to rotate. During the rotation of the driving ball head 52, it can successively contact the fixed hemispherical heads 53 at the bottom of the liquid guide plate 4, and can lift the liquid guide plate 4 through the fixed hemispherical heads 53, causing the liquid guide plate 4 to shake, further improving the range of the antifreeze flowing onto the filter screen plate 2.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
