[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1The present embodiment is a community kitchen waste vacuum collection system, comprising a garbage delivery box 1, a garbage dehydration device 2, an oil-water separator 3 and a microbial fermentation tank 4, the garbage delivery box is connected to the garbage dehydrator through a first pipe 5, a first valve 6 is installed on the first pipe, and a first vacuum pumping device 7 is installed on the garbage dehydrator. In the present embodiment, the first vacuum pumping device can be an existing vacuum pumping device such as a vacuum pump or an induced draft fan; the dehydration box is connected to the oil-water separator through a second pipe 8, a second valve 9 is installed on the second pipe; the dehydration box is connected to the microbial fermentation tank through a third pipe 10, and a third valve 11 is installed on the second pipe.

[0027] When the above-mentioned community kitchen waste vacuum collection system is in use, the community kitchen waste is first placed in the garbage disposal box for temporary storage, and then the first valve is opened, and the first vacuum device is started to generate negative pressure inside the garbage dehydration box. Under the action of negative pressure attraction, the community kitchen waste is sucked into the garbage dehydration box, and then the garbage dehydration box is started to dehydrate the community kitchen waste, so that the solid and liquid of the community kitchen waste are separated. The separated solid enters the microbial fermentation tank for fermentation, and finally produces fertilizer. The separated liquid enters the oil-water separator to separate the grease and water through the oil-water separator, and then is recycled. This collection system does not require centralized transportation of community kitchen waste and operations such as digging pits, saving a lot of manpower and material resources, and occupying less land.

[0028] In the above embodiment, the fermentation tank and the oil-water separator can use the existing structure. In actual production, the height of the garbage disposal box is preferably greater than the height of the garbage dehydration device; the height of the garbage dehydration device is greater than the height of the oil-water separator; the height of the microbial fermentation tank is less than the height of the garbage dehydration device, so that the kitchen waste can enter the next processing link in sequence.

[0029] In one embodiment, see Figure 2The garbage dehydration device includes a dehydration box 2-1, the top surface of the garbage dehydration box is provided with a feed port 2-2, and the feed port is connected to the first pipe; the bottom surface of the garbage dehydration box is provided with a discharge port 2-3 and a drain port 2-4, the discharge port is connected to the third pipe, the drain port is connected to the second pipe, the discharge port is located on one side of the garbage dehydration box, and the drain port is located on the other side of the dehydration box; a filter plate 2-5 is slidably arranged in the garbage dehydration box, and the filter plate is connected to a driving device 2-6 for driving the filter plate to move back and forth. In this embodiment, the driving device is a hydraulic cylinder, and the driving device is located on the side of the garbage dehydration box near the drain port. When the structure is in use, the third valve is first closed, the second valve is opened, and the driving device is started to push the filter plate to move to the right to squeeze the kitchen waste, squeeze out most of the liquid contained in the kitchen waste, and then the third valve is opened, and the fixed body after squeezing enters the microbial fermentation tank for fermentation operation. In order to facilitate the entry of the squeezed solid into the microbial fermentation tank, a second vacuum device, such as a vacuum pump, is installed on the microbial fermentation tank. What is needed is that the four-one valve, the second valve and the third valve in this embodiment can use manual valves, and preferably electric valves are used to facilitate automatic control. The opening and closing of the valves can be adjusted according to actual use. For example, the first valve can be closed during dehydration to prevent the foul odor from the kitchen waste from emanating upward during the dehydration process. When the second vacuum device is working, the first valve and the third valve are opened, and the second valve is closed. In the original state, all three valves are closed. This can be designed and operated by those skilled in the art according to actual conditions, and will not be repeated here.

[0030] Kitchen waste contains large objects such as bones, which are easy to block the discharge of kitchen waste after being put into the garbage disposal box, and the fermentation time will be greatly increased during fermentation. For this reason, the applicant has also made the following design, see Figure 3The garbage disposal box includes a garbage disposal box body 1-1, the top surface of the garbage disposal box body is provided with a garbage disposal port 1-2, the bottom surface of the garbage disposal box body is provided with a garbage discharge port 1-13, and the garbage discharge port is connected to the first pipe; a first roller 1-3, a second roller 1-4, a third roller 1-5, a fourth roller 1-6 and a fifth roller 1-7 are arranged in the garbage disposal box body, the first roller and the second roller are arranged horizontally, and a first gap 1-8 is arranged in the middle; the third roller, the fourth roller and the fifth roller are located below the first roller, a second gap 1-9 is arranged between the third roller and the first roller, and a third gap 1-10 is arranged between the fourth roller and the fifth roller; the second gap and the third gap are both smaller than the first gap; the third roller is arranged close to the side of the first roller, and the fourth roller and the fifth roller are arranged close to the side of the second roller; A triangular support 1-11 is arranged between the first and second rollers, the top angle of the triangular support is arranged upward, and the triangular support is arranged on one side close to the first roller; in actual production, the fifth roller can be arranged relative to the fourth roller away from the third roller, and the gap between the fifth roller and the second roller is smaller than the third gap, and the gap between the fourth roller and the bottom end of the triangular support is also smaller than the third gap; a power device for driving the first roller, the second roller, the third roller, the fourth roller and the fifth roller to rotate is arranged in the garbage delivery box, wherein the power device can be a motor, and the motor can be one, which controls the five rollers to rotate in the direction of the arrows mentioned above through gears and other structures, or it can be five, which controls the corresponding rollers to rotate separately, as long as the first roller and the second roller have opposite rotation directions, the third roller and the first roller have opposite rotation directions, the fourth roller and the second roller have opposite rotation directions, and the fifth roller and the fourth roller have opposite rotation directions, it will not be repeated here. This structure can realize that when the kitchen waste is delivered, the first roller and the second roller rotate in the direction of the arrows. Figure 3Rotate in the direction of the middle arrow to squeeze the garbage once. Large pieces of bones and other objects contained in the kitchen waste are destroyed, forming larger or smaller pieces of objects mixed in vegetable leaves, fruit peels and other garbage to form adulterations. When the adulteration passes through the triangular support, since the triangular support is set close to the side of the first roller, the gap between the triangular support and the first roller is smaller than the gap between the second roller. In this way, larger bones and other objects contained in the adulteration will enter the right side of the triangular support with the adulteration, move to the right under the action of the fourth roller and the first roller, and be squeezed twice, and move downward under the action of the fourth roller and the fifth roller, and be squeezed three times, and finally fall to the bottom of the delivery box; another part of the smaller objects enter the left side of the triangular support with the adulteration, move to the left under the action of the third roller and the first roller, and be squeezed twice, and finally fall to the bottom of the delivery box. In this way, large pieces of bones and other objects are destroyed once, and after sorting, the larger pieces are destroyed twice or three times, and the smaller pieces are destroyed twice, so that the kitchen waste finally forms a more uniform residue. In actual production, refer to Figure 4 , the second gap and the third gap can be set to be the same size. In order to facilitate the food waste to enter between the first roller and the second roller, the first roller and the second roller can also be provided with a toggle block 1-12, which has a toggle function when the food waste enters the first roller and the second roller, and can generate a shear force on the food waste when squeezing the food waste to assist in breaking large pieces of objects. Of course, other rollers can also be provided with a toggle block as needed.

[0031] As a preferred embodiment, the side wall of the garbage disposal box is provided with a shielding cover 1-14, the opening of the shielding cover is arranged upward, the top end is located in the middle of the garbage disposal box, connected to the side wall of the garbage disposal box, and the bottom end is connected to the bottom surface of the garbage disposal box; the bottom end of the shielding cover is provided with a hole arranged concentrically with the garbage discharge port; the longitudinal cross-section of the side wall of the shielding cover is arc-shaped, and this structure is conducive to guiding the kitchen waste to form a more uniform residue when it falls, so that the residue is close to the garbage discharge port, which is conducive to the discharge of the garbage to the garbage dehydration device.

[0032] During actual production, a cutter head capable of high-speed rotation can also be set in the garbage disposal box. Of course, in order to prevent the cutter head from being stuck by large pieces of bones, the cutter head can be set in conjunction with the five rollers mentioned above. A cutter head capable of high-speed rotation can be set in the left part between the first roller and the third roller, and a cutter head capable of high-speed rotation can be set in the lower part between the fourth roller and the fifth roller to further crush the residue.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
