[0024] Embodiment 1:

[0025] Please refer to Figures 1 to 3 , an automatic liquid skimming device for a centrifuge used for starch separation according to the present utility model, comprising a centrifuge 1, a detection mechanism 2 fixedly connected to the front end of the centrifuge 1, a metering mechanism 3 fixedly connected to the left end of the top of the centrifuge 1, and a centrifugal cylinder 4 rotatably connected to the inner bottom of the centrifuge 1;

[0026] The detection mechanism 2 includes a timer 21 fixedly connected to the front end of the centrifuge 1, a video recorder 22 fixedly connected to the left end inside the centrifuge 1, and a contact rod 23 fixedly connected to the left rear end of the top of the centrifugal cylinder 4. The contact rod 23 facilitates knocking on the flexible pad 212.

[0027] A mounting frame 24 is fixedly connected to the inner top of the centrifuge 1. A fixing plate 25 is fixedly connected to the bottom of the mounting frame 24. A sliding groove 26 is provided at the front end of the top of the fixing plate 25. Six electromagnetic blocks 27 are fixedly connected to the rear end inside the sliding groove 26. The electromagnetic blocks 27 are magnetically adsorbed to the sliding plate 28, and the electromagnetic blocks 27 facilitate driving the sliding plate 28 to move.

[0028] An arc-shaped sliding groove 29 is provided at the front end of the sliding plate 28. A first sliding rod 210 is slidably connected to the arc-shaped sliding groove 29. A second sliding rod 211 is fixedly connected to the back of the first sliding rod 210. The first sliding rod 210 facilitates driving the second sliding rod 211 to move.

[0029] A flexible pad 212 is fixedly connected to the bottom of the second sliding rod 211. A fixing rod 213 is fixedly connected to the left end of the sliding plate 28. A first control switch 214 is fixedly connected to the left front end of the top of the fixing plate 25. The video recorder 22 is electrically connected to the first control switch 214, and the first control switch 214 facilitates controlling the operation of the video recorder 22.

[0030] The second sliding rod 211 penetrates through the top of the mounting frame 24 and is slidably connected to its interior. The second sliding rod 211 penetrates through the fixing plate 25 and is slidably connected to its interior. The electromagnetic blocks 27 are electrically connected to an external current output device, and the sliding plate 28 is slidably connected to the sliding groove 26.

[0031] The working principle of an automatic liquid skimming device for a centrifuge used for starch separation based on Embodiment 1 is:

[0032] When it is necessary to detect the rotation speed of the centrifugal cylinder 4, the electromagnetic block 27 is driven to work step by step through an external current output device, so that the sliding plate 28 moves leftward under the magnetic influence of the electromagnetic block 27. The sliding plate 28 drives the arc-shaped chute 29 to move leftward. During the leftward movement of the arc-shaped chute 29, the second sliding rod 211 is driven to move downward in the mounting frame 24 through the first sliding rod 210. The second sliding rod 211 drives the flexible pad 212 to move downward. And during the leftward movement of the sliding plate 28, the fixed rod 213 is simultaneously driven to move leftward, so that the fixed rod 213 squeezes the first control switch 214, thereby driving the video recorder 22 to work through the first control switch 214. Then the staff controls the timer 21 to work. During the rotation of the centrifugal cylinder 4, the contact rod 23 is driven to do circular motion, so that the contact rod 23 knocks on the flexible pad 212. When the video recorder 22 records that the contact rod 23 knocks on the flexible pad 212, the video recorder 22 transmits an electrical signal to the timer 21, so that the timer 21 stops timing. The staff indirectly judges the rotation speed of the centrifugal cylinder 4 according to the time of the timer 21, ensures that the centrifugal effect of the centrifuge 1 reaches the best state, and improves the separation result.

[0033] Embodiment 2:

[0034] Please refer to Figure 4 , for an automatic liquid skimming device of a starch separation centrifuge of the present utility model, compared with Embodiment 1, this embodiment further includes: a quantitative mechanism 3. The quantitative mechanism 3 includes a U-shaped frame 31. The left end of the top of the centrifuge 1 is fixedly connected with a U-shaped frame 31. The right end inside the U-shaped frame 31 is fixedly connected with a connecting plate 32. The front end of the connecting plate 32 is rotatably connected with a rotating block 33. The connecting plate 32 is convenient for limiting the movement of the rotating block 33.

[0035] The front left side of the rotating block 33 is fixedly connected with a connecting rod 34. The right end of the connecting rod 34 is fixedly connected with a spring 35. The right end of the spring 35 is fixedly connected with a third sliding rod 36. A spring is sleeved on the outer wall of the third sliding rod 36.

[0036] The top of the third sliding rod 36 is fixedly connected with a placement box 37. And a feed port is provided at the top of the placement box 37. The placement box 37 is convenient for driving the third sliding rod 36 to move.

[0037] The bottom of the placement box 37 is fixedly connected with a delivery pipe 38. A solenoid valve 39 is fixedly connected at the delivery port of the delivery pipe 38. The left end of the top of the horizontal plate below the U-shaped frame 31 is fixedly connected with a second control switch 310.

The solenoid valve 39 is electrically connected to the second control switch 310. The delivery pipe 38 penetrates through the top of the centrifuge 1 and is slidably connected to its interior.

[0039] In this embodiment:

[0040]

[0040] In this embodiment, the staff conveys the coagulant into the placement box 37 through the top feed port of the placement box 37. As the coagulant in the placement box 37 increases, the placement box 37 drives the third sliding rod 36 to move downward under the influence of gravity. At this time, the spring sleeved on the lower end of the placement box 37 and the third sliding rod 36 is compressed to store energy. During the downward movement of the third sliding rod 36, the rotating block 33 is driven to rotate downward at the front end of the connecting plate 32 through the spring 35 and the connecting rod 34, so that the rotating block 33 squeezes the second control switch 310, thereby driving the solenoid valve 39 to work, enabling the coagulant in the placement box 37 to be conveyed into the centrifuge tube 4 through the delivery pipe 38. Then, the spring sleeved on the third sliding rod 36 provides a restoring force for the placement box 37, enabling the placement box 37 to be restored. By quantitatively increasing the coagulant, the starch particles are more likely to aggregate together under the centrifugal force field, accelerating the sedimentation speed, thereby improving the separation efficiency.
