[0024] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0025] Embodiment 1:

[0026] Reference Figure 1 The high-speed centrifugal slag separation device for meal residue shown in the figure comprises a separation box 1, wherein the separation box 1 is provided with a feed inlet 11, a liquid discharge outlet 12 and a slag discharge outlet 13, and a conical slag screen 22, a slag discharge trough 14 and a slag remover 23 are provided in the separation box 1, wherein the conical slag screen 22 is inverted in the separation box 1, and is driven to rotate by a driver 21 externally arranged at the bottom of the separation box 1, and the upper end of the conical slag screen 22 is a circular opening 221, and the circular opening 221 smoothly transitions from the inside to the outside of the conical slag screen 22, so that the conical slag screen 22 swings the meal residue under the driving rotation of the driver 21, and the liquid matter in the meal residue passes through the conical slag screen 22 into the separation box 1, and the solid matter in the meal residue is on the conical slag screen 22, along the conical The conical slag separator 22 is discharged toward the circular opening 221, and falls into the slag discharge trough 14 from the edge of the circular opening 221, so that the solid matter and liquid matter of the meal residue are separated; the slag discharge trough 14 is annularly distributed at the corresponding position of the edge of the circular opening 221 of the conical slag separator 22, and the notch of the slag discharge trough 14 is located below the edge of the circular opening 221. The slag discharge trough 14 is provided with a slag outlet 141, and the slag outlet 141 corresponds to the position of the slag outlet 13 of the separation box 1; the slag remover 23 is one or more material removal plates 231 provided on the slag discharge trough 14, and the material removal plates 231 rotate along the slag discharge trough 14, so that the solid matter of the meal residue in the slag discharge trough 14 is removed from the slag outlet 141 to the slag outlet 13.

[0027] In the embodiment, the separation box 1 is provided with an opening with a cover 15. The driver 21 is a motor provided at the bottom of the separation box 1, and the rotating shaft 211 of the motor penetrates into the separation box 1 and connects with the conical slag screen 22. The edge of the circular opening 221 transitions and extends to the slag trough 14. Specifically, the circular opening 221 is provided with an outwardly bent angled edge 222, and the circular opening 221 transitions and extends to the notch of the slag trough 14 through the angled edge 222, that is, the angled edge 222 extends to the side of the notch of the slag trough 14, so that when the conical slag screen 22 swings the food residue, the food residue is swung along the conical slag screen 22 to the edge of the circular opening 221 due to the action of centrifugal force, and discharged to the slag trough 14, and the solid matter of the food residue falls into the slag trough 14 along the angled edge 222 on the circular opening 221.

[0028] The slag trough 14 is a U-shaped groove, a semicircular groove or a V-shaped groove. The material-pickling plate 231 is a U-shaped groove, a semicircular groove or a V-shaped groove. The material-pickling plate 231 is used to push the kitchen waste fixed materials on the slag trough 14 to be discharged toward the slag outlet 141, and finally fall into the slag outlet 13 and then be discharged. During installation, the slag prying device 23 is installed on the edge of the circular opening 221 of the conical slag separation net 22, and rotates with the rotation of the conical slag separation net 22.

[0029] The separation box 1 is provided with a flushing nozzle 4, which flushes the conical slag separation net 22 by high-pressure water spray after the high-speed centrifugal slag separation device for meal slag is used, so that the conical slag separation net 22 can maintain good slag separation and discharge functions for a long time.

[0030] The conical slag screen 22 is a conical structure made of stainless steel sheet. The angle between the conical surface of the conical slag screen 22 and the plane of the conical slag screen 22 in the direction of rotation (such as Figure 1 The angle of the drive 21 (ie, the motor) is about 35-75°, and the stainless steel sheet is covered with through holes to form a filter screen. The drive 21 (ie, the motor) can automatically adjust the speed to 500-1000 / min, and the speed is set according to the angle of the conical slag screen 22. The larger the angle, the higher the speed and the higher the water output rate. The three are in a proportional relationship.

[0031] When the present invention is used, after the food residue enters the separation box 1, it falls into the conical slag separation net 22 through the circular opening 221, and the liquid material (oil and water) of the kitchen waste leaks through the mesh of the conical slag separation net 22 to the bottom of the separation box 1 and is discharged from the drain port 12. The solid material (leftovers) of the kitchen waste is separated on the conical slag separation net 22. At this time, the conical slag separation net 22 starts to rotate 360 ​​degrees quickly by starting the driver. Under the centrifugal force of high-speed rotation, the solid material gradually falls onto the circular opening 221 along the slope of the conical slag separation net 22, and then falls onto the slag discharge trough 14 from the edge of the circular opening 221. At this time, a large amount of liquid material is further thrown to the separation box 1 through the conical slag separation net 22, so that the solid and liquid materials of the kitchen waste are better separated. The solid material on the slag discharge trough 14 is moved by two material-pickup plates 231 symmetrically arranged at the upper part of the conical slag separation net 22, and the food residue is completely separated through the slag discharge port 13, and the water content of the slag is extremely low.
