DETAILED DESCRIPTION

[0025] The utility model will be further explained in detail in combination with the drawings. The drawing is simplified schematic view, just with schematic way to explain the basic structure of the utility model, so it just shows the structure related with the utility model.

[0026] Please refer to Figures 1-7The utility model relates to a centrifuge automatic skimming device, the skimming device is used in centrifuge in various fields, the centrifuge in the embodiment is arranged on the base 1, the bottom of base 1 is equipped with shock absorber 2 at four corners, the centrifuge includes centrifuge base 3, middle flap 4 and upper flap 5, the sealing and detachable connection between centrifuge base 3, middle flap 4 and upper flap 5, the connection between centrifuge base 3 and middle flap 4 is through flange hook 6, and the connection between middle flap 4 and upper flap 5 is through lock catch 7, wherein flange hook 6 and lock catch 7 can be purchased in the market, it is the connecting piece of ordinary prior art, here do not make too much repetition, wherein upper flap 5 is equipped with mounting hole 51, and the skimming device in the utility model is fixed with upper flap at mounting hole 51.

[0027] Specifically, the skimming device includes a drive box 9 and a rotating tube 91 that extends through the drive box 9. The bottom end of the rotating tube 91 is provided with a first elbow pipe 911. The end of the first elbow pipe 911 is provided with a second elbow pipe 912. The top end of the rotating tube 91 is provided with a rotary joint 93 for connecting an external pipeline. The rotary joint 93 is arranged to enable the external pipeline to be rotationally connected to the rotating tube 91. A driving mechanism is arranged in the drive box 9 to drive the rotating tube 91 to rotate. The driving mechanism drives the second elbow pipe 912 to rotate.

[0028] The rotating tube 91, the first elbow pipe 911 and the second elbow pipe 912 are integrated. The first elbow pipe 911 is bent in the vertical direction. The second elbow pipe 912 is bent in the horizontal direction. The second elbow pipe 912 always rotates in the horizontal direction. When the rotating drum rotates at high speed, the internal supernatant also rotates. When the port of the second elbow pipe 912 is aligned with the rotation direction, the liquid is sequentially sprayed out of the second elbow pipe 912, the first elbow pipe 911 and the rotating tube 91 to achieve internal skimming. Similarly, when the port of the second elbow pipe 912 is opposite to the rotation direction of the supernatant, the liquid cannot enter the second elbow pipe 912, so that skimming cannot be achieved.

[0029] In the embodiment, the driving mechanism includes a stepping motor 10, a transmission shaft 101, a worm wheel 914 and a worm 102. The stepping motor 10 is arranged on the outside of the drive box 9. One end of the transmission shaft 101 is coaxially connected to the stepping motor 10. The other end of the transmission shaft 101 extends outward through the drive box 9. The worm 102 is fixed to the circumference of the transmission shaft 101. The worm wheel 914 is fixed to the circumference of the rotating tube 91 by a fixing cylinder 913. The stepping motor 10 drives the rotating tube 91 to rotate by cooperating with the worm wheel 914 and the worm 102.

[0030] Wherein the stepper motor 10 can be controlled by PLC control program, the stepper motor 10 is controlled by pulse frequency to control rotating speed and rotating direction, whether to skim liquid is controlled by the stepper motor 10, control program and corresponding pulse signal, when skimming liquid is needed, the whole rotating pipe 91 rotates, the port of the second elbow pipe 912 is in line with the rotating liquid, because the rotating drum rotating speed is high, therefore the internal supernatant will be sprayed outwards through the second elbow pipe 912, the first elbow pipe 911 and the rotating pipe 91; when skimming liquid is not needed, the whole rotating pipe 91 reversely rotates, the port of the second elbow pipe 912 is opposite to the rotating liquid.

[0031] In the embodiment, the circumference of the worm wheel 914 is provided with a notch 915, the outer wall of the driving box 9 is provided with a limiting bolt 12, the limiting bolt 12 extends into the notch 915 through the side wall of the driving box 9; wherein the notch is semicircular, the worm wheel 914 is also semicircular, in addition, the end of the transmission shaft 101 is provided with a manual adjusting wheel 11, the adjusting wheel 11 is manually twisted to drive the rotating pipe 91 to rotate; because the notch is semicircular, therefore the rotating pipe 91 can rotate within the range of 0-180°, the water-encountering angle is adjusted within the range.

[0032] Wherein the limiting bolt 12 can also be replaced by a magnetic proximity switch reed tube sensor, the reed tube penetrator also extends into the notch 915, the reed tube inductes the inner wall of the worm wheel notch and generates a start signal to the stepper motor, so that the whole angle is adjusted.

[0033] The skimming device can be automatically rotated by the stepper motor, and can also be manually rotated by rotating the adjusting wheel 11, the usage is various and the practicability is strong.

[0034] When manually rotating, because the limiting bolt 12 extends into the notch 915, therefore the two walls (the inner wall of the notch) of the worm wheel 914 can touch the limiting bolt 12, when the inner wall of the notch cannot be rotated, the angle of the second elbow pipe is adjusted in reverse direction; when automatically rotating, because the circumference of the worm wheel 914 is provided with the notch 915, therefore the stepper motor can reciprocating rotate, that is, the forward and reverse rotation is timely adjusted, so that the second elbow pipe 912 is opposite to or away from the rotating liquid.

[0035] That is, because the circumference of the worm wheel 914 is provided with the notch 915, therefore the rotating pipe 91 can only rotate within the range of the worm and the worm gear cooperation, that is, the rotating pipe 91 can only reciprocating rotate within the range of avoiding the notch, the water-encountering angle is adjusted, and the skimming is realized; wherein the port of the second elbow pipe 912 always reciprocating swings in horizontal direction.

[0036] Based on the above embodiment, the port section of the second elbow pipe 912 can also be flat, that is, the port of the second elbow pipe 912 is duckbill-shaped.

[0037] Based on the above embodiment, the surface of the upper cover 5 is also provided with a feeding pipe 52, a washing pipe 53 and a feeding sensor mounting hole 54, and the end of the feeding pipe 52 and the washing pipe 53 is provided with a sanitary quick connector.

[0038] Based on the above embodiment, one side of the base 1 is also provided with a motor box 8 for driving the centrifuge to operate, the motor box 8 is provided with an inverted motor, the output shaft of the motor is provided with a belt pulley through the base, the lower part of the drum is provided with a rotating shaft, the rotating shaft is also provided with a belt pulley through the base, and the two belt pulleys are connected through a belt, so that when the motor in the motor box 8 operates, the drum in the centrifuge is driven to rotate at high speed through the belt pulley and the belt transmission connection.

[0039] Obviously, the above embodiment is only an example for clearly illustrating, but not a limitation to the embodiments. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments do not need to be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
