[0030] The present utility model provides an electric drive discharging device for a plate centrifuge through improvement, and its working principle is as follows;

[0031] First, when using this device, first place this device in the working area, and then connect the device to an external power supply and an external controller, which can provide the electric energy required for the operation of this device;

[0032] Second, first start the second motor 13 through the external controller. The second motor 13 drives the upper cover 12 to rotate through the output shaft, so that the upper end of the machine shell 2 is opened, allowing personnel to pour materials into the centrifuge drum 10. Then the second motor 13 drives the upper cover 12 to rotate through the output shaft to close the upper end of the machine shell 2. Then start the first motor 4. The first motor 4 provides power for the transmission member 5 through the output shaft, and the transmission member 5 drives the centrifuge drum 10 to rotate, thereby completing the centrifugation work of the materials;

[0033] Thirdly, when it is necessary to unload the inside of the centrifuge drum 10, first start the second motor 13. The second motor 13 drives the upper cover 12 to rotate through the output shaft, so that the upper end of the casing 2 is opened. Then start the third motor 64. The third motor 64 drives the rotating rod 62 to rotate through the output shaft. The rotating rod 62 will drive the components connected thereto to rotate. At the same time, start the cylinder 65, and let the cylinder 65 drive the connecting plate 66 to move upward along the rotating rod 62 through the telescopic rod, so that the scraper 612 moves above the centrifuge drum 10. Then start the electric push rod 611, and the electric push rod 611 extends the telescopic rod downward to drive the scraper 612 to move into the centrifuge drum 10. At the same time, start the fifth motor 69. The fifth motor 69 drives the rotating plate 610 to rotate through the output shaft, so that the scraper 612 can rotate, so that the scraper 612 can contact the inner wall of the centrifuge drum 10. Through the above operations, the scraper 612 can scrape the inside of the centrifuge drum 10 in all directions. At the same time, the centrifuge drum 10 rotates slowly, so that the materials on the inner wall and bottom of the centrifuge drum 10 can be scraped off by the scraper 612. Finally, let the materials accumulate on the side of the gland 11 that has been scraped clean. Then open the gland 11, and the centrifuge drum 10 rotates to align the discharge hole with the upper end of the discharge valve 8. Then start the fourth motor 67. The fourth motor 67 drives the threaded rod in the front groove of the connecting plate 66 to rotate through the output shaft, so that the threaded rod can move the moving plate 68 along the limiting rod in the front groove of the connecting plate 66, so that the moving plate 68 can drive the scraper 612 to move parallelly, so that the scraper 612 can push the accumulated materials into the discharge valve 8 to complete the unloading work;

[0034] Fourthly, when it is necessary to clean the scraper 612, first make the scraper 612 move above the cleaning box 72 through the above operations. Then move the scraper 612 inside the cleaning box 72, that is, inside the annular brush 74. Then start the sprinkler 73, so that the sprinkler 73 irrigates and flushes the scraper 612 and the inside of the cleaning box 72. At the same time, start the sixth motor 77. The sixth motor 77 drives the rotating wheel 76 to rotate through the output shaft. The rotating wheel 76 will drive the annular brush 74 to rotate, so that the rubber strip inside the annular brush 74 can scrub the surface of the scraper 612 to complete the cleaning work of the scraper 612. And after the cleaning work is completed, start the water discharge valve 78, and the water discharge valve 78 can discharge the water inside the cleaning box 72 to the outside.

[0035] The utility model provides an electric drive discharging device for a plate centrifuge through improvement. By arranging a discharging mechanism 6 on the left side of the top surface of a table 1, when it is necessary to discharge the materials inside a centrifuge drum 10, a third motor 64 provides a transposition power for a rotating rod 62 and other components connected thereto, so that a scraper 612 can move above the centrifuge drum 10. Then, with the cooperation of other components connected to the scraper 612, the scraper 612 can scrape the materials inside the centrifuge drum 10, so that the materials can reach the outside through a discharging valve 8. With a high degree of automation, the discharging process is convenient and fast, and the inside of the centrifuge drum 10 can be scraped comprehensively to avoid residues, improving the efficiency of the discharging work. By arranging a cleaning mechanism 7 on the discharging mechanism 6, after the discharging mechanism 6 finishes discharging the device and the residual materials adhered to the scraper 612 need to be cleaned, only need to let the discharging mechanism 6 drive the scraper 612 into the inside of an annular brush 74. Then, let a water sprinkling member 73 inject water into a cleaning box 72 and wash the scraper 612. At the same time, the annular brush 74 rotates to drive the rubber strip on its inner side to scrub the scraper 612, so that the scraper 612 can be comprehensively cleaned, avoiding residues from continuing to adhere to the surface of the scraper 612 and improving the speed at which the device can quickly carry out the next work.
