[0025] The utility model discloses a specific implementation mode, and the specific implementation mode is explained below in connection with the drawing.

[0026] As Figure 2 Shown, the separator of the utility model is based on the existing separator, is equipped with a plurality of emptying ports 21 in the bottom of drum 2, and the emptying pipe 9 is connected on the emptying port 21, and the emptying pipe 9 is communicated emptying port 21 and constitutes emptying channel 40, and emptying channel 40 is communicated the separation cavity in drum 2 and the inner chamber of casing 1. Emptying channel 40 is opened on drum 2 along the horizontal direction, and the center axis of emptying channel 40 is perpendicular to the rotation center shaft 30 of drum 2, which is conducive to avoiding the overflow of the material in drum 2 from emptying channel 40 when the separator is running, and facilitating the material in drum 2 to be smoothly discharged from emptying channel 40 after the shutdown of the separator.

[0027] The bottom of casing 1 is provided with a liquid leakage 12, and the liquid leakage 12 is communicated with the inner chamber of casing 1.

[0028] As Figure 2 、 Figure 3 Shown, the casing 1 ground central direction its inner chamber, inward convexly set up with sleeve 11, and the main shaft 3 is from the sleeve 11 central passage, and the inner chamber of casing 1 is connected with drum 2. The several emptying channels 40 on drum 2 are located on the outside of sleeve 11, and the discharge port 401 of emptying channel 40 is spaced apart from sleeve 11 by a certain distance d, to ensure the discharge space of emptying channel 40. The emptying channel 40 is arranged opposite to the sleeve 11, and the sleeve 11 can protect the main shaft 3, to prevent the material discharged from the emptying channel 40 from directly spraying and impacting on the main shaft 3 and penetrating into the gap between the main shaft 3 and the sleeve 11, thereby affecting the operation of the main shaft 3.

[0029] As Figure 2 、 Figure 3As shown, when the separator is running, the material in the rotating drum 2 rotates at high speed, and under the action of centrifugal force, the material moves to the periphery of the rotating drum 2, and the distance of outward movement of the material is different due to different densities of the material, and the greater the centrifugal force, the greater the distance of outward movement. Therefore, when the separator is running, the radius R1 of the light phase position 10 is smaller than the radius R2 of the heavy phase position 20. In order to ensure the smooth discharge of the light phase and the heavy phase, the radius of the inlet of the light phase centrifugal pump 7 is consistent with the radius R1 of the light phase position 10, and the radius of the inlet of the heavy phase centrifugal pump 8 is consistent with the radius R2 of the heavy phase position 20. When the separator is running, the movement distance of the light phase material under the action of centrifugal force will not be less than the radius R1 of the light phase position 10, and the movement distance of the heavy phase material will not be less than the radius R2 of the heavy phase position 20, that is, when the separator is running, the position of the material in the rotating drum 2 will not be close to the position of the light phase position 10.

[0030] As shown, Figure 3 The distance D from the discharge port 401 of the emptying channel 40 of the rotating drum 2 to the rotating center shaft 30 is set to be smaller than the radius R1 of the light phase position 10, that is, the position of the discharge port 401 of the emptying channel 40 is closer to the rotating center shaft 30 than the light phase position 10. Since when the separator is running, the position of the material in the rotating drum 2 will not be close to the light phase position 10, and the discharge port 401 of the emptying channel 40 is close to the light phase position 10, the material will not reach the discharge port 401, and therefore, when the separator is running, no material will overflow from the emptying channel 40. After the separator is stopped, the residual material in the rotating drum 2 will be discharged from the emptying channel 40 to the inner cavity of the casing 1 under the action of gravity, and then discharged from the liquid leakage port 12 of the casing 1.

[0031] The utility model discloses a plurality of emptying channels 40 are arranged at the bottom of the rotating drum 2, and the position of the discharge port 401 of the emptying channel 40 is set to be closer to the rotating center shaft 30 than the light phase position 10 when the separator is running, which can ensure that the material in the rotating drum 2 does not overflow from the emptying channel 40 when the separator is running, and at the same time, the residual material in the rotating drum 2 can be discharged through the emptying channel 40 after the separator is stopped, thereby saving the disassembly and assembly procedure of the rotating drum 2 after each separation operation, reducing the labor intensity, improving the production efficiency, and avoiding the safety risk caused by disassembling and assembling the rotating drum 2.

[0032] The above description is an explanation of the utility model, not a limitation of the utility model, and the utility model can be modified in any form without departing from the spirit of the utility model.
