By starting the electric push rod 44, the push rod portion of the electric push rod 44 is extended. The extension of the push rod portion of the electric push rod 44 drives the push plate 45 to extend. The extension of the push plate 45 causes the residue in the mixing barrel 3 to be pushed out of the mixing barrel 3 from the position of the door 46.

[0032] In order to allow the oil and water in the mixing barrel 3 to be quickly discharged into the oil-liquid separation box 4 through the pipe 13 and to protect the entire device, further, a slope 300 is provided at the bottom of the mixing barrel 3, and a protective shell 47 is fixedly connected to the upper surface of the bottom plate 1.

[0033] Working principle: The oil discharge device based on the catering wastewater oil separation equipment introduces the catering wastewater into the mixing barrel 3 through the catering wastewater pipe 17, and drives the rotating shaft 9 to rotate by starting the motor 18, and drives the disturbance rod 12 to rotate by the rotation of the rotating shaft 9. The residue in the catering wastewater can be broken up by the rotation of the disturbance rod 12, and the oil and water therein are precipitated from the residue, and discharged to the oil-liquid separation box 4 through the pipeline 13 for oil-water separation. By starting the motor 29, the rotating shaft 22 is driven to rotate under the action of the gear 2 30 and the gear 3 31, and the screw 23 is driven to rotate by the rotation of the rotating shaft 22, and the oil-water separation tank 4 is discharged through the pipeline 13. The rotation of the screw rod 23 drives the rotating shaft 3 24 to rotate around the rotating shaft 2 22 as the central axis. The movement of the rotating shaft 3 24 drives the connecting rod 4 27 to move. The movement of the connecting rod 4 27 drives the connecting rod 5 28 to make a reciprocating transverse movement in the piston cylinder 32. The movement of the connecting rod 5 28 drives the piston 33 to make a reciprocating movement. The movement of the piston 33 drives the air in the piston cylinder 32 to be compressed and replenished, and discharged to the aeration pipe 16 through the air outlet pipe 35. The aeration pipe 16 produces bubbles, which adsorb and separate the oil and water in the oil-liquid separation box 4, accelerate the oil to the top of the water, and achieve the oil-water separation effect.

[0034] The gravity of the wastewater drives the mixing barrel 3 to move downward. When wastewater is gradually added into the mixing barrel 3, the gravity of the mixing barrel 3 increases. Under the action of the spring 6, the mixing barrel 3 slowly moves downward. The downward movement of the mixing barrel 3 drives the fixed plate 18 to move downward. The downward movement of the fixed plate 18 drives the rotating plate 19 to move downward. The downward movement of the rotating plate 19 drives the rack row 1 20 to move downward. The downward movement of the rack row 1 20 drives the gear 1 201 to rotate. The rotation of the gear 1 201 drives the screw rod 23 to rotate. The rotation of the screw rod 23 drives the rotating shaft 3 24 to move left. The left movement of the rotating shaft 3 24 drives the connecting rod 4 27 to move left. The left movement of the connecting rod 4 27 drives the connecting rod 5 28 to move left. The piston 33 moves left through the left movement of the connecting rod 4 27. , so that the rotation radius of the connecting rod four 27 with the rotating shaft two 22 as the central axis becomes larger, thereby making the lateral movement trajectory of the connecting rod five 28 longer, and the lateral movement trajectory of the connecting rod five 28 becomes longer, so that the movement trajectory of the piston 33 becomes larger, so that the aeration speed of the piston cylinder 32 into the aeration pipe 16 is accelerated, so as to adapt to the increase in the amount of wastewater in the mixing barrel 3. The aeration speed of the aeration pipe 16 is accelerated, so that the processing speed in the oil-liquid separation box 4 can be automatically adjusted according to the amount of wastewater in the mixing barrel 3, so that the oil and water in the oil-liquid separation box 4 will not be highly nitrified due to the small amount of oil and water and the large amount of aeration, so that the nitrate concentration in the oil-liquid separation box 4 is increased, so as to achieve the effect of adaptively adapting to the amount of wastewater in the mixing barrel 3 so that the aeration amount changes dynamically;

[0035] When there is more waste water in the mixing barrel 3, the mixing barrel 3 moves downward due to gravity, driving the piston 33 to increase its lateral reciprocating motion trajectory. The increase in the stroke trajectory of the piston 33 drives the lateral motion trajectory of the slide bar 2 36 to increase. The motion trajectory of the slide bar 2 36 increases, driving the motion trajectory of the rack row 2 37 to increase, and the lateral reciprocating motion trajectory of the rack row 2 37 increases, driving the number of positive and negative rotations of the gear 40 to increase, thereby lengthening the vertical reciprocating motion trajectory of the rack row 31, thereby driving the vertical reciprocating motion trajectory of the connecting rod 6 42 to lengthen, and driving the vertical reciprocating motion of the connecting rod 6 42 to drive the vertical reciprocating motion of the collar 43. Through the movement of the collar 43, the sleeve block 10 is driven to reciprocate up and down. Through the movement of the sleeve block 10, the connecting rod 11 is driven to move. Through the movement of the connecting rod 11, the inclination angle of the disturbance rod 12 is driven to change all the time. By starting the motor 18, the rotating shaft 19 is driven to rotate. Through the rotation of the rotating shaft 19 , driving the disturbance rod 12 to rotate, through the rotation of the disturbance rod 12, the residue and wastewater can be disturbed, and the connection rod six 42 drives the change of the inclination angle of the disturbance rod 12, so that the residue and wastewater in the mixing barrel 3 can be fully disturbed and broken, and it is prevented that the residue and wastewater continue to rotate in the same horizontal plane and cause the disturbance and breaking effect to be poor. When there is a lot of wastewater in the mixing barrel 3, the vertical reciprocating motion distance of the connecting rod six 42 is increased, so that the vertical reciprocating motion distance of the sleeve block 10 becomes longer, thereby the movement range of the connecting rod one 11 is increased, which also drives the disturbance rod 12 to be tilted at a longer angle. By making the disturbance rod 12 tilt at a longer angle, when there is a lot of residue and wastewater in the mixing barrel 3, the disturbance rod 12 can adapt to the amount of wastewater so that the disturbance rod 12 is always immersed in the residue and wastewater, and it is prevented that the disturbance rod 12 cannot be completely immersed in the residue and wastewater, resulting in poor disturbance and stirring effect, and the residue cannot be well broken and oiled.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
