[0014] Compared with the related art, the present invention has the following beneficial effects:

[0015] When the present invention is used, initially, waste water is placed in the feed box, and enters the interior of the separation box from the feed port through the feed port, the first mesh plate is located below the feed port, and the first mesh plate and the second mesh plate are both in an inclined state, the waste water slides along the surface of the first mesh plate, and is filtered by the first mesh plate at the same time, grease and water are separated from leftovers, slides from the surface of the first mesh plate to the first chute surface of the first transverse plate, and then slides from the surface of the first transverse plate to the surface of the second mesh plate, and then filters, slides along the surface of the second mesh plate to the first chute surface of the second transverse plate, and then slides from the first chute surface to be discharged into the separation box through the rectangular hole, ensuring that the waste water stays in the separation box for a sufficient time, ensuring the separation effect of leftovers from grease and water, and as more and more waste water is added to the feed box, the separation As the weight of the separation box increases, the separation box moves downward, and the initial state of the first spring is a compressed state. The reaction force generated by the compression of the first spring acts on the surface of the circular block, which can support the separation box. The initial state of the second spring is a compressed state, and the separation box moves downward, and relative movement occurs between the second inclined slot and the fourth inclined slot. The surfaces of the second inclined slot, the third inclined slot and the fourth inclined slot are all rough, and as the separation box moves downward, the second spring is further compressed, so that the friction between the movable plate and the fixed plate becomes greater and greater, thereby supporting the separation box. The separation box moves downward, and the support column and the top plate move downward with the separation box. When the fourth inclined slot contacts the third inclined slot, the friction reaches the maximum value. At this time, the top plate cannot cooperate with the discharge port, and the convex block and The spiral groove cooperates to drive the rotating column to rotate, and then drives the connecting plate and the oil-absorbing cotton to rotate. The mixture of grease and water is discharged from the discharge port and placed on the surface of the oil-absorbing cotton to absorb the grease, thereby achieving the purpose of oil-water separation. As more and more wastewater is added to the separation box, the separation box continues to move downward, the fourth chute is separated from the third chute, and the movable plate contacts with multiple ball bearings. At this time, the force generated by the deformation of the first spring supports the separation box, and the separation box moves downward, driving the top plate to block the discharge port to avoid further addition of wastewater to the separation box, reaching the maximum amount of wastewater added at one time, and the movable plate continues to move downward to separate from the ball bearings. The movable plate contacts with the surface of the L-shaped plate. At this time, the protrusion moves to the other end of the spiral groove. Then, as the separation box continuously passes through the rectangular hole and As the material is discharged outward from the discharge port, the mass becomes smaller and smaller, the separation box gradually rises, and the top plate and the discharge port gradually separate. Since the setting of the ball bearing protrudes from the plane of the L-shaped plate, during the upward movement, the movable plate is in close contact with the surface of the L-shaped plate under the action of the elastic force of the second spring. The movable plate needs to overcome the elastic force of the second spring and cooperate with the ball bearing again, thereby being able to drive the L-shaped plate to move upward, and relative sliding occurs between the limit column and the L-shaped plate until the waste water added into the separation box completes the separation of leftovers from grease and water. The separation box returns to its initial position under the action of the first spring force. During the rising process of the separation box, when the L-shaped plate moves to the other end of the limit column, the L-shaped plate can no longer move upward, and relative sliding occurs between the movable plate and the L-shaped plate under the action of the elastic force of the first spring.Then it cooperates with the ball bearing and separates from the L-shaped plate. Under the action of gravity, the L-shaped plate returns to its initial position. The fourth inclined groove on the surface of the movable plate contacts the second inclined groove again. The convex block cooperates with the spiral groove to drive the adjustment block to rotate. The connecting plate rotates with the rotation of the rotating column, driving the oil-absorbing cotton to rotate, adsorbing the grease, and then completing the separation of water and oil, and ensuring the separation effect; when the separation box moves upward, the stepper motor drives the first bevel gear to rotate. Due to the transmission effect of the transmission bevel gear, it can drive the two second bevel gears to rotate at the same time, and then drive the two squeezing rollers to rotate at the same time. Since the surface of the squeezing roller is provided with grooves, initially, the two grooves contact the surface of the oil-absorbing cotton and the mounting ring. The squeezing roller rotates a certain angle driven by the stepper motor to squeeze the oil-absorbing cotton, so that the grease is separated from the oil-absorbing cotton, which is convenient for repeated use.

[0030] The initial state of the second spring 30 is a compressed state, which ensures that sufficient force can act on the surface of the T-shaped column 31, so that the movable plate 32 can be in close contact with the second inclined groove 37, providing sufficient friction force.

[0031] The first separation device 6 includes an adjusting block 40, a spiral groove 41, a rotating column 42, a connecting plate 43, a mounting ring 44 and oil-absorbing cotton 45.

The surface of the mounting plate 52 is located below the two second bevel gears 51 and is fixedly connected to the motor seat 47. A stepper motor 48 is installed on the surface of the motor seat 47, and the output end of the stepper motor 48 is fixedly connected to the first bevel gear 49.

A plurality of water outlets can be provided on the surface of the mounting ring 44, and a plurality of water outlet valves can be installed on the surface of the water outlets. The groove 54 contacts the surface of the oil-absorbing cotton 45. When the water outlet valve is opened and the mounting ring 44 and the squeezing roller 53 rotate relative to each other, the water on the surface of the oil-absorbing cotton 45 can be quickly discharged, and the grease can also be quickly discharged during squeezing.

[0034] It should be noted that a controller can be installed on the side of the U-shaped plate 1, and the stepper motor 48, the pressure sensor and the water outlet valve are all connected to the controller through wires. The controller is precisely controlled by a computer or other control terminal. Initially, the wastewater is placed in the feed box 3, and enters the interior of the separation box 7 from the feed port 4 through the feed port 9. The first mesh plate 23 is located below the feed port 9. The first mesh plate 23 and the second mesh plate 25 are both in an inclined state. The wastewater slides along the surface of the first mesh plate 23 and is filtered by the first mesh plate 23 at the same time. Grease and water are separated from leftovers and slide from the surface of the first mesh plate 23 to the surface of the first chute 27 of the first transverse plate 24, and then slide from the surface of the first transverse plate 24 to the surface of the second mesh plate 25, and then filtered. The surface of the first spring 20 slides to the surface of the first chute 27 of the second cross plate 26, and then slides from the surface of the first chute and is discharged into the separation box 7 through the rectangular hole 11, ensuring that the waste water stays in the separation box 7 for a sufficient time to ensure the separation effect of leftovers, grease and water. As more and more waste water is added to the feed box 3, the weight of the separation box 7 becomes heavier, and the separation box 7 moves downward. The initial state of the first spring 20 is a compressed state. The reaction force generated by the compression of the first spring 20 acts on the surface of the circular block 21, which can support the separation box 7. The initial state of the second spring 30 is a compressed state, and it moves downward toward the separation box 7. Relative movement occurs between the second chute 37 and the fourth chute 39, and the surfaces of the second chute 37, the third chute 38 and the fourth chute 39 The second spring 30 is further compressed, so that the friction between the movable plate 32 and the fixed plate 33 becomes larger and larger, thereby supporting the separation box 7. The separation box 7 moves downward, and the support column 12 and the top plate 13 move downward with the separation box 7. When the fourth chute 39 contacts the third chute 38, the friction reaches the maximum value. At this time, the top plate 13 is unable to cooperate with the discharge port 4, and the protrusion 16 cooperates with the spiral groove 41 to drive the rotating column 42 to rotate, thereby driving the connecting plate 43 and the oil-absorbing cotton 45 to rotate. The mixture of grease and water is discharged from the discharge port 10 and placed on the surface of the oil-absorbing cotton 45 to absorb the grease, thereby achieving the purpose of oil-water separation. As more and more waste water is added to the separation box 7, the separation box 7 continues to The movable plate 32 contacts the surface of the L-shaped plate 34, and the protrusion 16 moves to the other end of the spiral groove 41. Then, as the separation box 7 continuously discharges materials through the rectangular hole 11 and the discharge port 10, the mass becomes smaller and smaller, and the separation box 7 gradually rises, and the top plate 13 gradually separates from the discharge port 4. As the setting of the ball 36 protrudes from the plane of the L-shaped plate 34,During the upward movement, the movable plate 32 is in close contact with the surface of the L-shaped plate 34 under the elastic force of the second spring 30. The movable plate 32 needs to overcome the elastic force of the second spring 30 and cooperate with the ball 36 again, thereby driving the L-shaped plate 34 to move upward, and relative sliding occurs between the limit post 35 and the L-shaped plate 34 until the waste water added to the separation box 7 completes the separation of leftovers, grease and water. The separation box 7 returns to its initial position under the elastic force of the first spring 20. During the rising process of the separation box 7, when the L-shaped plate 34 moves to the other end of the limit post 35, the L-shaped plate 34 It cannot move upward any further. Under the elastic force of the first spring 20, the movable plate 32 and the L-shaped plate 34 slide relative to each other, and then cooperate with the ball 36 to separate from the L-shaped plate 34. Under the action of gravity, the L-shaped plate 34 returns to its initial position. The fourth inclined groove 39 on the surface of the movable plate 32 contacts the second inclined groove 37 again. The convex block 16 cooperates with the spiral groove 41 to drive the adjusting block 40 to rotate. The connecting plate 43 rotates with the rotating column 42, driving the oil-absorbing cotton 45 to rotate, adsorbing the grease, and then completing the separation of water and oil, and ensuring the separation effect and separation efficiency.

[0035] During the process of the L-shaped plate 34 and the separation box 7 rising, the top plate 13 is separated from the feeding port 4, and the feeding continues, so that the whole process can be connected continuously;

[0036] When the separation box 7 moves upward, the stepper motor 48 drives the first bevel gear 49 to rotate. Due to the transmission action of the transmission bevel gear 50, the two second bevel gears 51 can be driven to rotate at the same time, thereby driving the two squeezing rollers 53 to rotate at the same time. Since the surface of the squeezing roller 53 is provided with a groove 54, initially, the two grooves 54 do not contact the surface of the oil-absorbing cotton 45 and the mounting ring 44. The squeezing roller 53 is driven by the stepper motor 48 to rotate a certain angle to squeeze the oil-absorbing cotton 45, so that the grease is separated from the oil-absorbing cotton 45.
