Description

Technical Field

[0001] This utility model relates to the technical field of kitchen waste pretreatment equipment, specifically an integrated kitchen waste pretreatment machine. Background Technology

[0002] Food waste pretreatment equipment is a device that can transform food waste into something easier to process or reuse. It typically consists of processes such as crushing, compression, separation, and fermentation. Food waste, also known as swill, is household waste generated in daily life. It is prone to emitting foul odors and spreading bacteria. Food waste pretreatment equipment can effectively decompose and process food waste, reducing its volume or transforming it into reusable resources.

[0003] According to Chinese patent application number 202321667389.6, an integrated food waste treatment device is disclosed, including four supports. Damping blocks are fixedly connected to the top of two first telescopic cylinders, and a second outer shell is fixedly connected above the two damping blocks. An extrusion rod is rotatably connected inside the second outer shell. Traditional integrated food waste treatment devices are not very functional. When processing waste, the first step is to crush the waste by a motor-driven crushing device, which causes significant vibration and makes the entire device unstable. The device is equipped with a buffer component. The first telescopic cylinder can minimize the shaking generated by the extrusion rod when it is working. In addition, the damping blocks above it and the outer damping shell can greatly reduce the noise generated by the extrusion rod when it is working, thereby increasing the stability and noise reduction function of the device.

[0004] The comparative case effectively solves the problem of equipment shaking during operation in existing food waste pretreatment equipment, enabling stable operation and reducing shaking. However, existing technologies mainly deal with food waste in two ways: one is simple crushing and dehydration followed by oil-water separation, such as the integrated food waste treatment device in the comparative case. This method has poor separation effect and low oil extraction rate, which cannot meet the current requirements for food waste treatment; the other is project-based, with the pretreatment system divided into four major systems: material receiving, pulping and sorting, solid-liquid separation, and three-phase oil extraction. Each process section requires corresponding equipment. Although this technology can meet the current requirements for food waste treatment, it requires large investment, large equipment area, and long installation period, which brings inconvenience to food waste treatment operations.

[0033] Example 3

The slurry in the inner cavity of the box 211 can be transported to the inner cavity of the first storage tank 6 by the conveying pump.

[0038] Example 4

[0039] Reference Figure 1-3 This is the fourth embodiment of the present invention, which is based on the previous three embodiments.

[0040] In this embodiment, the solid-liquid separation mechanism 4 includes a housing 401, a fourth motor 402, a second reducer 403, a second feed box 404, a connecting pipe 405, a filter cartridge 406, a third auger 407, a discharge port 408, and a liquid discharge pipe 409. The housing 401 is fixedly connected to the support platform 3. The output shaft of the fourth motor 402 is drivenly connected to the input end of the second reducer 403.

The discharge port 408 is installed on the other side of the housing 401. One end of the liquid outlet pipe 409 is connected to the housing 401, and the other end of the liquid outlet pipe 409 is connected to the inner cavity of the three-phase oil lifter 5. One end of the third auger 407 extends to the inner cavity of the second feed box 404 and passes through to the outside of the second feed box 404, and is connected to the output end of the second reducer 403.

[0042] like Figure 1-3As shown, the slurry in the inner cavity of the first storage tank 6 is transported to the inner cavity of the second feed box 404 through the connecting pipe 405. A conveying pump can be installed at the discharge end of the first storage tank 6 to cooperate with the connecting pipe 405 to transport the slurry. The output shaft of the fourth motor 402 rotates to drive the second reducer 403 to rotate. When the second reducer 403 rotates, it drives the third auger 407 to rotate. When the third auger 407 rotates, it drives the slurry into the inner cavity of the filter cartridge 406. The filter cartridge 406 can screen the slurry.

The solids in the slurry are gradually squeezed into blocks under the spiral conveying of the third auger 407 and discharged through the discharge port 408.

[0043] In use, kitchen waste is first received by receiving mechanism 1. After entering the inner cavity of storage bin 112, the kitchen waste is initially screened by screen 115. The liquid in the kitchen waste passes through screen 115 and enters the inner cavity of hopper 113. The separated liquid is transported to the inner cavity of third storage tank 8 for subsequent purification treatment. The output shaft of first motor 124 rotates, driving first sprocket 125 to rotate. When first sprocket 125 rotates, it drives second sprocket 126 to rotate via chain, so that second sprocket 126 can drive first auger 122 to rotate in the inner cavity of first conveying pipe 121. When the auger 122 rotates, it drives the solid food waste in the inner cavity of the storage bin 112 to be conveyed to the pulping mechanism 2 through the first conveying pipe 121 and the first discharge pipe 123. The pulping mechanism 2 then performs pulping. The solid food waste conveyed by the first conveying component 12 falls into the inner cavity of the first feed bin 223. The output shaft of the third motor 225 rotates, driving the first reducer 226 to rotate. This causes the first reducer 226 to drive the second auger 224 to rotate within the inner cavity of the second conveying pipe 221. When the second auger 224 rotates, it drives the solid food waste through the second discharge pipe 222 into the inner cavity of the box 211. The second motor 212... The output shaft rotates, driving the transmission rod 213 to rotate, which in turn drives the pulverizing blade 214 to pulverize and mix the kitchen waste, turning it into a slurry. The slurry in the inner cavity of the tank 211 can be pumped to the inner cavity of the first storage tank 6 for storage. The slurry in the inner cavity of the first storage tank 6 is then pumped to the inner cavity of the second feed box 404 through the connecting pipe 405. A conveying pump can be installed at the discharge end of the first storage tank 6 in conjunction with the connecting pipe 405 to transport the slurry. The output shaft of the fourth motor 402 rotates, driving the second reducer 403 to rotate. When the second reducer 403 rotates, it drives the third auger 407 to rotate. When the third auger 407 rotates, it drives the slurry into the inner cavity of the filter cylinder 406. The filter cylinder 406 can screen the slurry. The liquid in the slurry is filtered by the filter cylinder 406 and discharged through the liquid outlet pipe 409 into the inner cavity of the three-phase oil extractor 5 for oil extraction. The solids in the slurry are gradually squeezed into blocks under the screw conveying of the third auger 407 and discharged through the discharge port 408. The three-phase oil extractor 5 uses centrifugal force to separate the liquid. The separated oil is discharged into the inner cavity of the second storage tank 7 for storage, and the separated wastewater is discharged into the inner cavity of the third storage tank 8 for storage. This can perform pre-treatment of kitchen waste and reduce the pollution caused by kitchen waste.
