Detailed implementation manners

[0037] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0038] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0039] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate or selectively exclusive of other embodiments.

[0040] Furthermore, the present invention will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional views showing the device structures will be enlarged locally not in accordance with the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0041] Embodiment, a separation system for kitchen waste with an oil-water separation device, including a separation device 100, a preselection rack 200, and an outer cylinder 300;

[0042] Reference Figure 1 and 2 At the top of the separation device 100, an access pipe 101 is installed.

[0043] The preselection rack 200 and the outer cylinder 300 are installed in the separation device 100. The preselection rack 200 is located above the outer cylinder 300. A first grille 201 is installed in the preselection rack 200. The first grille 201 is inclined. A gate 202 is milled on the side of the preselection rack 200. The gate 202 is electrically driven. A collecting tank 203 is installed in the separation device 100.

[0044] Through the above, it can be realized that the kitchen waste is introduced into the preselection rack 200 through the access pipe 101. The first grille 201 mostly isolates the food residues. The opening of the gate 202 and the shaking of the cam 205 cooperate to introduce this part of the food material into the collecting tank 203, and these food materials can be recycled.

[0045] Reference Figure 1 and 2 Above the separation device 100, a first motor 204 is installed. A cam 205 is arranged on the back of the first grille 201. The cam 205 and the first motor 204 are linked by a transmission belt.

[0046] Through the above, it can be realized that the movement of the cam 205 can provide a shaking effect for the first grille 201, and further improve the discharging effect of the food residues on the first grille 201.

[0047] Reference Figure 3 , 4 and 5, an inner square cylinder 305 is installed in the outer cylinder 300. A first channel 306 is milled on the outer periphery of the inner square cylinder 305. A separation rack 307 is installed in the first channel 306 in a telescopic motion manner. A second grille 308 is installed at the edge of the separation rack 307. A dredging module 321 is installed in the inner square cylinder 305. The dredging module 321 is used to operate the separation rack 307 to perform telescopic motion and acts on the second grille 308 for dredging.

[0048] Reference Figure 2 and 3 Above the outer cylinder 300, a docking pipe 301 is installed. The upper part of the docking pipe 301 is docked with the preselection rack 200, and the lower part of the docking pipe 301 is docked with the inner square cylinder 305. The waste liquid for kitchen use can be introduced into the inner square cylinder 305. A second channel 302 is milled at the lower part of the outer cylinder 300. A hollow sleeve 303 is arranged at the lower part of the outer cylinder 300 and opposite to the second channel 302. An outlet pipe 304 is docked on the hollow sleeve 303.

[0049] Reference Figure 7 and 8, the dredging module 321 includes a swivel base 322, a second motor 323, a first vertical column 324, a first cooperative base 325, and a second vertical column 326. The second motor 323 is installed on the back of the outer cylinder 300. The swivel base 322 is disposed at the moving part of the second motor 323. The first vertical column 324 is installed on the swivel base 322 and is not at the central position of the swivel base 322. The first cooperative base 325 is installed at the part of the first vertical column 324 deviating from the swivel base 322. The second vertical column 326 is installed on the other side of the first cooperative base 325. A second cooperative base 327 is installed at another part of the second vertical column 326. A first cooperative arm 328 is hinged on the second cooperative base 327. The joint point of the first cooperative arm 328 and the second cooperative base 327 is not at its central position. The docking relationship between the first cooperative arm 328 and the separation frame 307 is hinged. After the second motor 323 is controlled, the swivel base 322 will perform a swivel motion. At this moment, the first vertical column 324, the first cooperative base 325, the second vertical column 326, and the second cooperative base 327 move together with the swivel base 322. With the cooperation of the first cooperative arm 328, the separation frame 307 can change its position in terms of expansion and contraction. Several separation frames 307 alternately treat the kitchen waste liquid and introduce it to the position of the second channel 302;

[0050] Refer to Figure 10 , a second displacement seat 337 and a first displacement seat 334 are installed in the separation frame 307. A first dredging strip 335 and a second dredging strip 338 are arranged on one side of the first displacement seat 334 and the second displacement seat 337 facing the separation frame 307. The first dredging strip 335 and the second dredging strip 338 dredge the second grille 308;

[0051] Refer to Figure 10 , a guide frame 336 is arranged on one side of the first displacement seat 334. The guide frame 336 is in telescopic motion docking with the inner edge of the separation frame 307. A third elastic part 339 is installed at the middle position between the guide frame 336 and the other inner edge of the separation frame 307. The first displacement seat 334 can be installed with the same reset part as the second displacement seat 337. When the first displacement seat 334 performs telescopic motion, it relies on the first dredging strip 335 to act on the corresponding second grille 308 of the second grille 308 for dredging treatment. Similarly, when the second displacement seat 337 performs telescopic motion, it relies on the second dredging strip 338 to act on the corresponding second grille 308 of the second grille 308 for dredging treatment;

[0052] Refer to Figure 7 and 8, a fixed ring 329 is installed on the upper side of the revolving base 322, and the fixed ring 329 is fixedly connected to the inner cylinder 305 through a bearing arm. A continuous tooth groove pattern is milled on the inner edge of the fixed ring 329. A linkage disk 330 is installed on the outer contour of the vertical column 324. A continuous tooth groove pattern is milled on the outer edge of the linkage disk 330. The fixed ring 329 and the linkage disk 330 are engaged. When the vertical column 324 is rotated by the motor 323, the vertical column 324 relies on the engagement of the linkage disk 330 and the fixed ring 329 during this process, so that when the vertical column 324 rotates around the center of the motor 323, it also rotates around its own center;

[0053] Refer to Figure 9 and 10 , a cooperation arm 331 is hinged on the cooperation seat 325. The connection point of the cooperation arm 331 on the cooperation seat 325 is not at its central position. A guiding arm 332 is hinged on the part of the cooperation arm 331 facing the separating frame 307. The other part of the guiding arm 332 extends into the separating frame 307 and is connected to the displacement seat 334. The middle position of the guiding arm 332 moves telescopically on the separating frame 307. An extension seat 333 is installed at the middle position of the guiding arm 332 extending into the separating frame 307. The two sides of the extension seat 333 are sloping edges. The displacement seat 337 abuts against the sloping edges of the extension seat 333. When the cooperation seat 325 rotates, it controls the guiding arm 332 to move telescopically on the separating frame 307 by relying on the cooperation arm 331. The cooperation between the guiding arm 332 and the extension seat 333 enables the displacement seat 337 and the displacement seat 334 to move together and in different directions.

[0054] Through the above content, the following can be achieved: after the motor 323 is controlled, the revolving base 322 will perform a revolving motion. At this moment, the vertical column 324, the cooperation seat 325, the vertical column 326, and the cooperation seat 327 move together with the revolving base 322, and with the cooperation of the cooperation arm 328, the separating frame 307 can change its position telescopically. Several separating frames 307 alternately treat the kitchen waste liquid and introduce it to the position of the channel 302;

[0055] When the vertical column 324 is rotated by the motor 323, the vertical column 324 relies on the engagement of the linkage disk 330 and the fixed ring 329 during this process, so that when the vertical column 324 rotates around the center of the motor 323, it also rotates around its own center. When the cooperation seat 325 rotates, it controls the guiding arm 332 to move telescopically on the separating frame 307 by relying on the cooperation arm 331. The cooperation between the guiding arm 332 and the extension seat 333 enables the displacement seat 337 and the displacement seat 334 to move together and in different directions;

[0056] When the displacement seat 1-334 undergoes telescopic movement, it relies on the dredging strip 1-335 to act on the corresponding position of the grid 2-308 to dredge the grid 2-308 at the corresponding position. Similarly, when the displacement seat 2-337 undergoes telescopic movement, it relies on the dredging strip 2-338 to act on the corresponding position of the grid 2-308 to dredge the grid 2-308 at the corresponding position.

[0057] Refer to Figure 6 and 10 , a channel 3-314 is milled on the lower side of the separation frame 307. A bearing pad 309 is hinged on the channel 3-314. The cooperation of the channel 3-314 and the bearing pad 309 converges the slag generated during the dredging of the grid 2-308;

[0058] Refer to Figure 5 , a bearing frame 310 is installed outside the separation frame 307. The bearing frame 310 is fixedly connected to the edge of the inner cylinder 305. A T-column 311 undergoes a through-type telescopic movement on the bearing frame 310. A cone seat 312 is fixedly connected to the part of the T-column 311 facing the separation frame 307. An elastic member 1-313 is installed at the middle position between the bearing frame 310 and the cone seat 312. The elastic member 1-313 surrounds the outer periphery of the T-column 311. Under the action of the elastic member 1-313, the contact between the cone seat 312 and the grid 2-308 can be ensured. When the separation frame 307 undergoes telescopic movement, the dredging effect on the grid 2-308 can be improved;

[0059] Refer to Figure 6 , a fixed platform 315 is arranged at the lower side of the separation frame 307. A notch is milled on the upper side of the fixed platform 315. A fan-shaped frame 316 is hinged at the notch position of the fixed platform 315. An elastic member 2-317 is installed at the middle position between the fan-shaped frame 316 and the inner edge of the fixed platform 315. A collection space 318 is milled on the surface of the part of the fixed platform 315 far from the inner cylinder 305. An anti-overflow arc plate 319 is installed at the opening of the collection space 318. A storage box 320 can be arranged directly below the fixed platform 315 facing the collection space 318. When the separation frame 307 undergoes telescopic movement outward, the corner position of the separation frame 307 will press the fan-shaped frame 316 to rotate towards the middle of the fixed platform 315. When the bearing pad 309 is displaced to face the fan-shaped frame 316, relying on the elastic member 2-317, the fan-shaped frame 316 will flip towards the position of the separation frame 307. The fan-shaped frame 316 acts on the bearing pad 309, causing the bearing pad 309 to flip. Under the inclined action, the slag is guided into the collection space 318 through the channel 3-314. Under the action of the anti-overflow arc plate 319, the slag can be prevented from overflowing, and the storage space can be expanded through the storage box 320;

[0060] Through the above, the following can be achieved: Some slag materials will reach the separation rack 307 by relying on the grille two 308. This part of the slag materials will accumulate and move to the lower position of the separation rack 307. The bearing pad 309 bears this part of the slag materials. When the separation rack 307 makes a telescopic movement, when the separation rack 307 makes a telescopic movement outward, the corner position of the separation rack 307 will press the fan rack 316 to rotate towards the middle of the fixed table 315. When the bearing pad 309 is displaced to face the fan rack 316, relying on the elastic member two 317, the fan rack 316 will turn towards the position of the separation rack 307. The fan rack 316 acts on the bearing pad 309, causing the bearing pad 309 to flip. Under the action of the inclination, the slag materials are introduced into the collection space 318 through the channel three 314. Under the action of the elastic member one 313, the contact between the cone seat 312 and the grille two 308 can be ensured. When the separation rack 307 makes a telescopic movement, the dredging effect on the grille two 308 can be improved.
