[0029] The sewage enters the dehydration filter chamber, and can be filtered through the filter holes of the filter barrel 2. The residue in the sewage will remain in the dehydration filter chamber. The centrifugal force generated by the rotation of the filter barrel 2 can continue to discharge the water in the residue, and the residue can be squeezed by the extrusion device to further discharge the water in the residue. The residue after the water is discharged can be discharged outdoors by the discharging device. At this time, the residue is basically dry, and the sewage has been treated, and will not cause pollution to the environment.

[0030] The extrusion device includes a barrel 3 fixed on the housing 1, and also includes a column 4 located in the barrel 3, the barrel 3 is provided with a plurality of movable pushed columns 32, the column 4 is fixed with a plurality of pushing columns 41 that cooperate with the pushed columns 32, and a power device 5 for driving the filter barrel 2 and the column 4 to rotate is installed at the bottom of the housing 1;

[0031] When the residue is squeezed and drained, the filter barrel 2 and the cylinder 3 are driven to rotate by the power device 5. The rotation of the filter barrel 2 generates centrifugal force, and the column 4 will turn to make the pushing column 41 push the pushed column 32, so that the pushed column 32 moves into the dehydration filter chamber, and the residue can be squeezed.

[0032] The discharge device includes an air charging mechanism 6 and a suction mechanism 7. The air charging mechanism 6 includes an electric air charging box 65 fixed outside the housing 1, and also includes a plurality of exhaust pipes 63 arranged on the column 4 and connected to the dehydration filter chamber. The air outlet end of the electric air charging box 65 is connected to the exhaust pipe 63. The suction mechanism 7 includes a suction fan 71 fixed outside the housing 1, and also includes a plowing rod 72 located at the top of the dehydration filter chamber. The plowing rod 72 is fixed below the suction pipe 74. A heating pipe 75 is fixed and connected between the suction pipe 74 and the air inlet of the suction fan 71.

[0033] After the moisture of the residue is discharged, high-pressure gas can be input into the dehydration filter chamber through the electric inflation box 65 to loosen the residue, and as the filter barrel 2 continues to rotate, the plowing rod 72 can plow the residue on the top of the dehydration filter chamber to loosen it, and the suction fan 71 can be started to suck away the loose residue. During the suction, the heating tube 75 will dry the residue, so that the dried residue can be recycled.

[0034] Specifically, Figure 4-Figure 7 As shown, the power device 5 includes a motor 51 fixed outside the shell 1, and also includes a mounting seat 52 fixed at the bottom of the filter barrel 2, the mounting seat 52 is fixedly mounted with a mounting frame 53, the mounting frame 53 is fixedly mounted on the output shaft of the motor 51, the bottom of the filter barrel 2 is provided with a bottom hole 57, the bottom of the cylinder 3 is fixedly mounted with a circular seat 55, the circular seat 55 is provided with a circular stable groove 56, the bottom of the filter barrel 2 is rotatably mounted in the circular stable groove 56, the bottom of the circular seat 55 is fixedly mounted with a gear reduction box 54, the gear reduction box 54 is connected to the end of the output shaft of the motor 51 through a coupling, the bottom of the column 4 is installed with a base 42, and the power shaft of the gear reduction box 54 is fixedly connected to the base 42;

[0035] The motor 51 can drive the mounting base 52 to rotate, and the mounting base 52 can drive the filter barrel 2 to rotate at high speed, so that it generates centrifugal force for dehydration. The output shaft of the motor 51 is decelerated through the gear reduction box 54, so that the power shaft of the gear reduction box 54 drives the column 4 to rotate, which reduces the rotation speed of the column 4 but increases its torque, so that the pushing column 41 can push the pushed column 32 to move.

[0036] Specifically, a plurality of slots 31 are formed on the surface of the cylinder 3, and the pushed posts 32 are located in the slots 31, and a rubber belt 33 is fixedly installed between the pushed posts 32 and the slots 31;

[0037] When the column 4 rotates, the pushing column 41 will be pushed when passing the pushed column 32, so that the rubber belt 33 is stretched. When the pushing column 41 moves away, the rubber belt 33 will rebound and drive the pushed column 32 to reset, so that the pushed column 32 moves back and forth, so that the residue is continuously squeezed and the water is discharged.

[0038] In this embodiment, if Figure 5As shown, the cylinder 3 also includes a circular frame 34, the circular frame 34 is provided with an air delivery groove 35, and a plurality of exhaust holes 64 are provided on the surface of the air delivery groove 35. The inflation mechanism 6 also includes a through hole 62 provided on the column 4. The push column 41 includes an exhaust circular box 61, the exhaust circular box 61 is connected to the through hole 62, and a plurality of exhaust pipes 63 are fixed and connected to the circumference of the exhaust circular box 61. The exhaust circular box 61 is slidably installed in the air delivery groove 35, and a mounting sleeve 66 is fixedly installed in the top of the through hole 62. The mounting sleeve 66 is rotatably connected to a connecting pipe 67. This arrangement can ensure the normal rotation of the column 4 and can deliver air to the through hole. The air outlet end of the electric inflation box 65 is fixed and connected to an air delivery pipe 68, and the air delivery pipe 68 and the connecting pipe 67 are fixed and connected. A door body 100 is provided at the exhaust hole 64, and a torsion spring 200 is provided between the door body 100 and the wall of the air delivery groove 35.

[0039] The electric inflator 65 is started to deliver gas, and the gas can be delivered to the through hole 62 through the gas delivery pipe 68 and the connecting pipe 67, and finally delivered to the exhaust round box 61. The gas in the exhaust round box 61 is discharged from the exhaust pipe 63 to the gas delivery groove 35, and finally the door body 100 is opened by air pressure, so that the gas is discharged from the exhaust hole 64 to the dehydration filter chamber;

[0040] It should be noted that the gas delivery groove 35 can be sealed by the exhaust circular box 61, ensuring that the gas has sufficient pressure to be discharged from the circular frame 34, and through the setting of the torsion spring 200, the door body 100 can only be opened from the inside of the gas delivery groove 35 to the outside, ensuring that residues will not enter.

[0041] In this embodiment, if Figure 3 As shown, the suction pipe 74 passes through the top of the shell 1, the suction pipe 74 is fixed and connected to the suction head 73, the plowing rod 72 is fixed in the suction head 73, the heating pipe 75 is provided with an electric heating pipe 76, and the suction fan 71 is provided with a discharge port 77.

[0042] When the residue is loose, it is sucked into the suction pipe 74 through the suction head 73 and then enters the heating pipe 75. The gas can be heated by the electric heating pipe 76 to dry the residue. Finally, the dried residue will be discharged from the discharge port 77.

[0043] In addition, in the present embodiment, both sides of the shell 1 are provided with drain ports 11, the sewage chamber 10 is connected to the drain port 11, a sewage hopper 8 is fixedly installed on the top of the shell 1, the sewage hopper 8 is fixed and connected to a sewage pipe 9 whose end is located in the dehydration filter chamber, the shell 1 is provided with two symmetrically arranged stabilizing plates 300, the filter barrel 2 is located between the two stabilizing plates 300, the bottom of the shell 1 is provided with a slope 12 arranged around the filter barrel 2, a treatment box 13 is fixed outside the shell 1, the treatment box 13 is connected to the drain port 11, a sewage suction plate 15 is inserted in the treatment box 13, and the treatment box 13 includes a drain pipe 14;

[0044] After being filtered in the filter barrel 2, the sewage is discharged into the sewage chamber 10. Through the slope 12, the sewage is discharged from the drain port 11 into the treatment box 13. The sewage entering the treatment box 13 can absorb the oil through the sewage absorption plate 15. Finally, the treated sewage can be directly discharged from the drain pipe 14. In this way, the sewage generated by the rural mobile kitchen is completely treated and will not cause damage to the environment.

[0045] Working principle: Before operation, firstly energize all components, then discharge kitchen sewage into the sewage hopper 8, and then input sewage into the dehydration filter chamber through the sewage pipe 9, and filter sewage through the filter holes of the filter barrel 2, so that the residue remains in the dehydration filter chamber, and wait for a few minutes until the sewage is no longer discharged, and then start the motor 51, the motor 51 drives the mounting frame 53 to rotate, so that the filter barrel 2 rotates, and the centrifugal force is generated by the high-speed rotation of the filter barrel 2, and the sewage in the residue is discharged through the filter holes again, and at this time, the motor 51 will also drive the column 4 to rotate through the gear reduction box 54, and the rotation of the column 4 will cause the push column 41 to rotate, and when the push column 41 rotates, it will contact with the pushed column 32, so that the push column 32 will be pushed, and the rubber belt 33 will be stretched, and the push column 32 will move into the dehydration filter chamber to squeeze the residue, so that the water in the residue is discharged again, so that the sewage can be completely discharged;

[0046] The discharged sewage enters the sewage chamber 10, and then enters the treatment box 13 through the drain port 11. The oil in the sewage can be adsorbed by the sewage absorption plate 15, so that the deoiled sewage is discharged from the drain pipe 14. In this way, the sewage meets the discharge standard and will not cause pollution to the environment.

[0047] When sewage is no longer discharged, start the electric gas filling box 65, and the gas generated by the electric gas filling box 65 is discharged into the through hole 62 through the gas pipe 68, and then the gas enters the exhaust round box 61 and is discharged into the gas delivery tank 35 from the exhaust pipe 63, and then is discharged into the dehydration filter chamber through the exhaust hole 64, which can blow the residue loose;

[0048] Start the suction fan 71 to generate suction. At this time, the motor 51 continues to work, so that the residue continues to rotate in the filter barrel 2. The blown residue will be loosened, and the plowing of the plowing rod 72 will make all the residue on the top loosened, so that the residue can be sucked into the suction head 73 through the plowing rod 72 by suction, and the residue is transported to the heating pipe 75 through the suction pipe 74. The electric heating pipe 76 can heat the air, so that the residue will be dried, and finally the residue will be discharged from the discharge port 77. The discharged material has been dehydrated and can be used, thus protecting the environment.
