Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] Please refer to Figs. 1-2 The utility model provides a kind of technical scheme: a kind of convenient and efficient full-automatic unloading centrifuge, including support 1 and shell 2, support 1 is fixed with shell 2, support 1 is rotatably connected with one end of flip cylinder 3, the other end of flip cylinder 3 is rotatably connected on centrifuge cover 4, centrifuge cover 4 is rotatably connected on shell 2, motor 5 of shell 2 outside is provided with being fixed on support 1, the output shaft of motor 5 is connected with transmission shaft 6 by belt pulley and belt, transmission shaft 6 bearing is connected on shell 2, transmission shaft 6 is fixed with centrifugal drum 7 being arranged in shell 2.

[0028] Support 1 lower end is fixed with shock absorber 8, and shock absorber 8 is provided with four;Shell 2 is provided with residual liquid pipe 201, and shell 2 lower end is provided with discharge port 202;Centrifuge cover 4 is installed with feed pipe 401, and feed pipe 401 is bent by 45 ° from top to bottom to centrifugal drum 7 inner wall;Centrifuge cover 4 upper end surface is installed with observation port 402, and centrifuge cover 4 upper end surface is installed with illuminating lamp 403, and centrifuge cover 4 is installed with emptying pipe 404, while centrifuge cover 4 is also installed with cleaning pipe 405, and cleaning pipe 405 is connected with high pressure flushing water pump by conduit;Centrifuge cover 4 is also installed with skimming device 9, and skimming device 9 is installed with telescopic skimming pipe 10;Centrifugal drum 7 is installed with liquid baffle 701 at equal angles, and liquid baffle 701 is half open structure;The bottom of centrifugal drum 7 is inclined circular structure, and the bottom of centrifugal drum 7 is smooth with the side of centrifugal drum 7;

[0029] When using the convenient and efficient full-automatic unloading centrifuge, such as Fig. 1 And Fig. 2As shown, before the material is fed into the centrifuge, the centrifuge is first started to the feeding frequency, the motor 5 drives the transmission shaft 6 and the centrifugal drum 7 to the corresponding speed, the emptying pipe 404 is connected to the dedicated tail gas pipe to balance the positive pressure in the centrifugal drum 7 after feeding to facilitate smooth feeding, then the external feeding pump is started, the material is introduced through the feeding pipe 401 on the centrifuge cover 4, the material is uniformly dispersed to the inner wall of the centrifugal drum 7, the setting of the feeding frequency is based on the centrifugal force of the material entering the centrifugal drum 7 being greater than the gravity it receives, so as not to directly fall into the discharge port 202, but to be distributed horizontally to the wall of the centrifugal drum 7 for calculation and determination, after the material is completely fed into the centrifuge, the motor 5 adjusts the speed of the centrifugal drum 7 to the high-speed centrifugal frequency, at which the material is separated, at this time the shock absorber 8 at the bottom of the support 1 plays a role in maintaining the smooth operation of the centrifuge, the liquid splashed during centrifugation enters the outer shell 2 outside the centrifugal drum 7 and is discharged along the residual liquid pipe 201, the time setting of the high-speed centrifugal frequency is determined according to the density of the solid and liquid in the material and the viscosity of the liquid, to ensure that the solid in the material can be completely separated from the water layer, and the solid adheres to the inner wall of the centrifugal drum 7 without damaging the solid material structure due to excessive centrifugal force and too tight material;

[0030] After the high-speed centrifugation time is over, the action needed is skimming, i.e. removing the liquid layer inside and outside the centrifugal drum 7 after the material is separated, first the speed of the centrifugal drum 7 is reduced to the skimming frequency by the motor 5, the skimming frequency is relatively low, which is to prevent the pipe opening of the skimming pipe 10 from colliding with the liquid layer at too great an impact when the skimming pipe 10 is moved, the waste liquid is gradually skimmed out of the centrifuge and into the rear-end waste water treatment process, during the centrifugation and skimming processes, the inside of the centrifugal drum 7 can be observed through the lighting lamp 403 and the observation port 402 installed above the centrifuge cover 4, so as to adjust the process in time.

[0031] After skimming is completed, the solid material state can be checked, only the centrifuge cover 4 needs to be opened by the flipper oil cylinder 3, after being completely opened, manual observation of the material state and sampling of the solid material can be performed, after sampling, the centrifuge cover 4 is closed by continuing to control the flipper oil cylinder 3, then the solid material flushing operation can be performed, during this process, the flipper oil cylinder 3 replaces manual operation to ensure good sealing of the cover and safety of personnel;

[0032] In the solid material flushing link, firstly control the motor 5 forward rotation to raise the frequency of the centrifugal drum 7 to a lower rotating speed, then control to open the high-pressure flushing pump to enter water, after passing through the cleaning pipe 405, the water is flushed out from several flushing nozzles at a designed angle, forming a pure water cleaning full coverage environment with different flushing intensity, after several seconds, control the motor 5 to adjust the centrifugal drum 7 to reverse rotation for secondary flushing, after the pure water flushing, the solid materials adhered to the inner wall of the centrifugal drum 7 will be dropped together with the flushing water in a fluid state, reach the through-type bottom discharge port 202 along the slope bottom plate of the drum bottom, then enter the next process operation, after repeatedly adjusting the forward and reverse rotation for several times, stop the high-pressure flushing water pump operation in turn, then reduce the centrifuge rotating frequency to 0HZ and stop rotating. Therefore, the whole process of sequentially material centrifugation, liquid layer skimming and solid material discharge is completed, at the same time, the centrifuge interior is also cleaned, and the next material can be accepted, which is the working principle of the convenient and efficient full-automatic unloading centrifuge.
