[0025] Example

[0026] Please refer to Figure 1-4 As shown, the utility model provides a technical solution: a filtering device for a centrifuge;

[0027] The inner end of the feed box 1 is fixedly installed with a mounting bar 4, the front end of the mounting bar 4 is rotatably installed with a diverter plate 5, the front end of the diverter plate 5 is fixedly installed with a linkage rod 6, the outer end of the linkage rod 6 is rotatably installed with a fixing bar 8, the front end of the linkage rod 6 is fixedly installed with a linkage plate 7, and the left end of the feed box 1 is fixedly installed with a filter plate 17, and the filter plate 17 is located on the left side of the diverter plate 5. The feed box 1 is set to be high on the right and low on the left, wide on the right and narrow on the left. The left end of the feed box 1 is fixedly installed with a buffer plate 15, and the buffer plate 15 is located on the inner side of the mounting box 14. The left end of the feed box 1 is fixedly installed with a feed port 18. A fixing box 16 is fixedly installed at the front end of the feed box 1, a micro servo motor 2 is fixedly installed inside the fixing box 16, a moving block 11 is snap-fitted inside the fixing box 16, a discharge port 13 is fixedly installed at the right end of the discharge box 3, a mounting box 14 is fixedly installed at the upper end of the discharge box 3, and the mounting box 14 is fixedly installed at the left end of the feed box 1, so as to facilitate the diversion of the filtered liquid and increase the uniformity of the contact between the liquid and the filter plate 17. According to the amount of liquid, the upper and lower groups of feed boxes 1 can be selected to work simultaneously or individually to improve the filtering effect;

[0028] A micro threaded screw 12 is fixedly installed at the output end of the micro servo motor 2, and the outer end of the micro threaded screw 12 is threadedly connected to a moving block 11, and a driving rod 10 is rotatably installed on the upper end of the moving block 11. A moving bar 9 is snap-fitted onto the upper end of the driving rod 10, and the moving bar 9 is rotatably installed with the left end of the linkage piece 7, which is convenient for automatic adjustment of the angle and is flexible and convenient to use.

[0029] Specific working principle:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the centrifuge filtering device is used, the liquid to be treated in the centrifuge is first added to the inside of the feed box 1, and the liquid to be filtered is added from the feed port 18, and then moves to the left after passing through the diversion and stock separation of the diverter plate 5, so that the liquid is no longer concentrated in the lower part of the feed box 1 and flows to the left, and the setting of the feed box 1 being wide on the right and narrow on the left allows the liquid to better contact with the filter plate 17, thereby increasing the uniformity of the contact between the liquid and the filter plate 17. When the inclination angle of the diverter plate 5 needs to be adjusted, the micro servo motor 2 is started, and the output shaft of the micro servo motor 2 drives the micro threaded screw 12 to rotate when it rotates, and the micro threaded screw 12 rotates when the moving block 11 moves upward, and when the moving block 11 moves upward, the moving block 11 drives the driving rod 10 to move upward, and when the driving rod 10 moves upward, it drives the left end of the linkage plate 7 to rotate upward, so that the linkage rod 6 and the diverter plate 5 rotate downward, because the linkage plate 7 has an arc-shaped rotation trajectory, and the arc-shaped groove in which the moving bar 9 and the driving rod 10 are mounted can meet the activity trajectory of the moving bar 9 when it moves. When the diverter plate 5 is adjusted to the required angle, the output shaft of the micro-servo motor 2 can stop rotating. The different angles of the diverter plate 5 can play different guiding roles on the liquid. The feed box 1 is provided with two groups. If the flow rate is large or the liquid to be filtered is large, the upper and lower groups of feed boxes 1 can work at the same time to achieve a more refined filtering effect, avoiding that the liquid is filtered through a group of filter plates 17, resulting in poor filtering effect. Then, the liquid filtered by the filter plate 17 enters the interior of the installation box 14, and enters the interior of the discharge box 3 after being buffered by the buffer plate 15, and then is added to the interior of the centrifuge from the discharge port 13 for subsequent processing. The above completes a series of operations of the centrifuge filtering device. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
