Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] See also Figure 1 and Figure 2 , the utility model provides a technical solution:

[0027] A liquid mixture filtering device comprises a frame 1 and a stirring tank 2 and a filtering tank 3 both arranged on the frame 1; a first feed pipe 4 connected to the interior of the stirring tank 2 is arranged on the frame 1; a second feed pipe 5 is vertically arranged on the top of the filtering tank 3; a stirring mechanism is arranged in the stirring tank 2, and the liquid mixture stirred by the stirring mechanism can flow into the filtering tank 3 through the second feed pipe 5; a variable cross-section filtering assembly is arranged in the filtering tank 3, and the variable cross-section filtering assembly is located below the second feed pipe 5.

[0028] In this embodiment, the stirring tank 2 is used to hold the liquid mixture to be filtered. The stirring mechanism is used to fully stir the liquid mixture in the stirring tank 2. A variable cross-section filter assembly is installed in the filter tank 3. The variable cross-section design can reduce the retention of the liquid mixture on the variable cross-section filter assembly, thereby reducing the probability of its filter holes being blocked, thereby increasing the filtering speed of the liquid mixture.

[0029] In some implementations of this embodiment, the variable cross-section filter assembly includes at least two groups of variable cross-section filter mechanisms with different filtering capabilities. The two groups of variable cross-section filter mechanisms are arranged in the filter tank 3 with upper and lower intervals, and are both located below the second feed pipe 5.

[0030] In this embodiment, by installing multiple sets of variable cross-section filtering mechanisms, the stirred liquid mixture can be filtered according to usage requirements so that the liquid mixture meets the usage standards.

[0031] In some implementations of this embodiment, any variable cross-section filtering mechanism includes a conical filter screen 6 , the central axis of the conical filter screen 6 is colinear with the central axis of the second feed pipe 5 , and the sharp corner of the conical filter screen 6 faces the second feed pipe 5 .

[0032] In this embodiment, the variable cross-section filtering mechanism adopts a conical filter screen 6, which can achieve a filtering effect on the one hand; on the other hand, the outer surface of the conical filter screen 6 is an inclined surface, which can reduce the retention amount of the liquid mixture on the outer surface of the conical filter screen 6, thereby reducing the probability of the filter hole being blocked. Figure 1 As shown, the liquid mixture stirred by the stirring mechanism flows into the filter tank 3 through the first discharge pipe and the second feed pipe 5 in sequence, and first flows to the upper conical filter screen 6, and then flows to the lower conical filter screen 6 for secondary filtration after being filtered by the upper conical filter screen 6 to improve the filtering effect. The mesh number of the upper conical filter screen 6 can be smaller than the mesh number of the lower conical filter screen 6 to achieve the purpose of step-by-step filtration. The number of conical filter screens 6 can be increased or decreased according to actual conditions.

[0033] In some implementations of this embodiment, the outer side wall of any conical filter screen 6 is provided with a blocking groove.

[0034] In this embodiment, the blocking groove is used to block and store particles that cannot pass through the mesh of the conical filter screen 6 .

[0035] In some implementations of this embodiment, the blocking groove is a spiral blocking groove 7 .

[0036] In this embodiment, the blocking groove is designed to be spiral, so as to intercept particles that cannot pass through the sieve holes of the current conical filter screen 6 .

[0037] In some implementations of this embodiment, the stirring mechanism includes a driving mechanism 9 arranged on the stirring tank 2, a rotating shaft 10 located in the stirring tank 2, and a plurality of stirring blades 11 arranged at intervals on the rotating shaft 10. The rotating shaft 10 is rotatably connected to the stirring tank 2, and one end thereof is transmission-connected to the driving mechanism 9.

[0038] In this embodiment, the driving mechanism 9 is used to control the rotation of the rotating shaft 10, so that the rotating shaft 10 can drive a plurality of stirring blades 11 installed thereon to fully stir the liquid mixture.

[0039] In some implementations of this embodiment, the driving mechanism 9 is a motor. In other implementations of this embodiment, the driving mechanism 9 can also use a handle to control the rotation of the rotating shaft 10.

[0040] In some implementations of this embodiment, a first discharge pipe 12 communicating with the interior of the stirring tank 2 is disposed at the bottom thereof, the first discharge pipe 12 is communicated with the second feed pipe 5 , and a first valve 13 is disposed on the first discharge pipe 12 .

[0041] In this embodiment, the liquid mixture stirred by the stirring mechanism can flow into the filter tank 3 through the first discharge pipe 12 and the second feed pipe 5 in sequence. The first valve 13 is used to control the on-off of the first discharge pipe 12. When stirring, the first valve 13 is closed, so that the liquid mixture in the stirring tank 2 cannot be discharged into the filter tank 3; after stirring, the first valve 13 can be opened.

[0042] In some implementations of this embodiment, a second discharge pipe 14 communicating with the interior of the filter tank 3 is disposed at the bottom thereof, and a second valve 15 is disposed on the second discharge pipe 14 .

[0043] In this embodiment, the stirred liquid mixture can be discharged through the second discharge pipe 14 after being filtered by the variable cross-section filter assembly. The second valve 15 is used to control the on-off of the second discharge pipe 14. When filtering, the second valve 15 is closed, so that the second discharge pipe 14 cannot discharge material; after filtering, the second valve 15 is opened to discharge material.
