Description

Kitchen waste solids treatment equipment

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 29, 2023, with application number 202311608489.6. The entire contents of the above application are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of household appliances, for example, to equipment for processing kitchen waste solids. Background Art

[0003] Household kitchen waste refers to a mixture of various food scraps produced when people process food in the kitchen, such as plant roots, meat scraps, bones, fruit peels, etc. Kitchen waste has a high water content. If stored in a humid environment for a long time, it will rot and deteriorate, causing bacteria to accumulate, producing odors and leading to environmental pollution in the kitchen. Therefore, the kitchen will be equipped with waste solid treatment equipment to treat the waste solids.

[0004] In the related art, there is a non-standalone waste processor installed under the sink as a kitchen appliance. The blade is driven by an AC or DC motor, and the centrifugal force is used to crush the food waste in the crushing chamber and discharge it into the sewer. The direct discharge of food waste into the sewer after crushing does bring a certain degree of convenience to users, but it increases the risk of waste clogging the sewer. Therefore, a standalone waste processor has gradually emerged. This method of waste disposal directly processes and recycles the food waste into dry solids instead of sending it into the sewer.

[0005] Independent household food waste disposers mainly rely on grinding to process food waste, but the actual grinding experience is poor. They can only grind some smaller and lower hardness food waste, but cannot grind bones and shells with higher hardness. This requires users to screen them before use. If food waste with high hardness such as bones is put in, it will cause irreversible damage to the independent disposer, thereby hindering the convenience of use.

[0033] The present embodiment provides a kitchen waste solid material processing device. As shown in Figures 1 to 10, the kitchen waste solid material processing device includes a housing 100 and a pre-processing device 200, a reprocessing device 300, a collecting device 400, a first channel device 500, and a second channel device 600 installed in the housing 100. The first channel device 500 is arranged between the pre-processing device 200 and the reprocessing device 300 and connects the pre-processing device 200 and the reprocessing device 300. The second channel device 600 is arranged between the reprocessing device 300 and the collecting device 400 and connects The reprocessing device 300 and the collection device 400 are configured as follows: the preprocessing device 200 includes a first storage chamber 210 and a low-speed mincing mechanism 220. The first storage chamber 210 is used to hold the kitchen waste solids to be processed, and the low-speed mincing mechanism 220 is installed in the first storage chamber 210. The reprocessing device 300 includes a second storage chamber 310 and a high-speed mincing mechanism. The second storage chamber 310 is used to hold the kitchen waste solids pre-processed by the preprocessing device 200, and the high-speed mincing mechanism is installed in the second storage chamber 310. By providing the preprocessing device 200, the low-speed mincing mechanism 220 is used to first process large, hard, and difficult-to-process kitchen waste solids such as bones and shells. The high-speed mincing mechanism in the reprocessing device 300 then fully grinds the food waste solids, improving the quality of the food waste solids. Finally, the waste solids are collected by the collection device 400. Through the two distinct waste solids processing stages, namely preprocessing and reprocessing, the waste solids can be fully ground. The low-speed mincing mechanism 220 is configured to preliminarily crush and decompose the waste solids that are more difficult to process, and then the high-speed mincing mechanism further refines and grinds the waste solids, thereby improving the processing quality of the kitchen waste solids and making it easier to decompose and decompose them into useful components, thereby completing the pollution-free, rapid, and high-quality processing of the kitchen waste solids.

[0034] The low-speed mincing mechanism 220 in this embodiment includes a first rotating base 221, a low-speed rotary blade 222, and a first rotating drive 223. The low-speed rotary blade 222 is rotatably mounted on the first rotating base 221. The output end of the first rotating drive 223 is connected to the low-speed rotary blade 222, and the first rotating drive 223 is configured to rotate the low-speed rotary blade 222. The low-speed rotary blade 222, which rotates at 5 revolutions per minute, can be used for pre-processing to ensure initial crushing and decomposition of difficult-to-process solid waste.

[0035] The high-speed mincing mechanism in this embodiment includes a second rotating base 321, a high-speed rotary cutter 320, and a second rotating drive 322. The high-speed rotary cutter 320 is rotatably mounted on the second rotating base 321. The output end of the second rotating drive 322 is connected to the high-speed rotary cutter 320, and the second rotating drive 322 is configured to rotate the high-speed rotary cutter 320. The high-speed rotary cutter 320 can be selected for grinding at 30,000 revolutions per minute to ensure sufficient grinding of the waste solids.

[0036] The first channel device 500 in this embodiment includes a first channel housing 510 and a first closing mechanism 520. The first channel housing 510 is internally provided with an arcuate channel 5101, which facilitates the flow of solid waste within the first channel housing 510 and prevents blockage. The first channel housing 510 defines a first inlet 511 and a first outlet 512. The first inlet 511 communicates with the pre-processing device 200, while the first outlet 512 communicates with the reprocessing device 300. The arcuate channel 5101 connects the first inlet 511 and the first outlet 512, thereby transferring solid waste from the pre-processing device 200 to the reprocessing device 300. A first closing mechanism 520 is slidably mounted on the first channel housing 510 and configured to open or close the first inlet 511. The provision of the first closing mechanism 520 prevents the accumulation of solid waste and the resulting blockage in the reprocessing device 300, thereby facilitating waste processing within the food waste treatment apparatus.

[0037] In this embodiment, a sliding groove 513 is provided on one side of the first channel shell 510 connected to the pretreatment device 200. The first closing mechanism 520 includes a first sliding plate 521, a first transmission assembly 522 and a first driving member 524. The first sliding plate 521 is slidably installed in the sliding groove 513. The first transmission assembly 522 and the first driving member 524 are both installed in the first channel shell 510. The first transmission assembly 522 is transmission-connected to the first sliding plate 521. The first driving member 524 is configured to drive the first transmission assembly 522 to drive the first sliding plate 521 to slide in the sliding groove 513 to open or cover the first entrance 511.

[0038] In this embodiment, the first transmission assembly 522 includes a first rack 5221 and a first drive gear 5222. The first rack 5221 is mounted on the first sliding plate 521, and the first drive gear 5222 is mounted on the first channel housing 510. The first drive gear 5222 is meshed and transmission-connected with the first rack 5221. The output end of the first driving member 524 is connected to the first drive gear 5222, and the first driving member 524 is configured to drive the first drive gear 5222 to rotate. The first driving member 524 drives the first drive gear 5222 to rotate, and the first drive gear 5222 transmits power to the first rack 5221. Since the first rack 5221 is connected to the first sliding plate 521, the first sliding plate 521 can move within the sliding slot 513. Alternatively, the first driving member 524 in this embodiment may be a stepping motor.

[0039] In this embodiment, the sliding groove 513 is recessed within the groove body to form a first blocking portion 5131. The end of the sliding groove 513 is formed as a second blocking portion 5132. The first closing mechanism 520 further includes a stopper 523 mounted on the bottom surface of the first sliding plate 521. When the first sliding plate 521 opens the first inlet 511, the first blocking portion 5131 abuts the stopper 523. When the first sliding plate 521 blocks the first inlet 511, the second blocking portion 5132 abuts the end of the first sliding plate 521. This arrangement limits the open and closed positions of the first sliding plate 521. Because the first blocking portion 5131 is recessed and positioned at a different height than the second blocking portion 5132, the second blocking portion 5132 abuts the side surface of the end of the first sliding plate 521. The first blocking portion 5131 abuts the stopper 523. The provision of the second blocking portion 5132 reduces the length of the sliding groove 513, thereby reducing the space occupied by the reprocessing device 300. The limiting member 523 is provided at the bottom end of the first sliding plate 521 to prevent the accumulation of waste solids to be processed.

[0040] In this embodiment, the second channel device 600 includes a second channel housing 610 and a second closing mechanism 620. The second channel housing 610 defines a grinding waste solids channel 611, which connects the reprocessing device 300 and the collection device 400. The second closing mechanism 620 is slidably mounted on the second channel housing 610 and configured to open or close the grinding waste solids channel 611. The waste solids ground by the reprocessing device 300 can enter the collection device 400 through the grinding waste solids channel 611 for collection. The second closing mechanism 620 limits the amount of ground waste solids that pass through, preventing accumulation in the reprocessing device 300 or the collection device 400, thereby effectively ensuring the quality of waste solids treatment.

[0041] Exemplarily, the second closing mechanism 620 in this embodiment includes a sliding rail 621, a second sliding plate 622, a second rack 623, a second drive gear 624 and a second drive member 625. The sliding rail 621, the second drive gear 624 and the second drive member 625 are all installed on the second channel housing 610. The sliding rail 621 is arranged on both sides of the opening of the grinding waste solid channel 611. The second sliding plate 622 is slidably installed in the sliding rail 621. The second rack 623 is installed at the bottom of the second sliding plate 622. The second drive gear 624 is meshed and transmitted with the second rack 623. The output end of the second drive member 625 is connected to the second drive gear 624. The second drive member 625 is configured to drive the second drive gear 624 to rotate, so as to drive the second rack 623 to drive the second sliding plate 622 to open or cover the grinding waste solid channel 611. The second driving member 625 drives the second driving gear 624 to rotate, and the second driving gear 624 drives the second rack 623 to move. Since the second rack 623 is installed on the second sliding plate 622, the second sliding plate 622 can move in the sliding track 621, thereby completing the opening or closing of the grinding waste solid channel 611.

[0042] Optionally, the second channel device 600 in this embodiment further includes an oblique outlet pipe 630, which is installed at the end of the grinding waste solids channel 611. The oblique outlet pipe can extend the path of the grinding waste solids and reduce the impact force of the grinding waste solids, providing a buffering effect for the collection device 400 and preventing significant impact on the collection device 400.

[0043] The beneficial effects of this application are:

[0044] In the kitchen waste solid material processing equipment provided by the present application, a pre-treatment device is provided, and a low-speed grinding mechanism is used to first process large, hard bones and shells and other difficult-to-process kitchen waste solid materials, and then a high-speed grinding mechanism in the re-processing device is used to fully grind them, thereby improving the quality of kitchen waste solid material processing. Finally, a collection device is used to collect the waste solids. Through two different waste solid material processing stages, namely pre-treatment and re-processing, the waste solids can be fully ground. The low-speed grinding mechanism is set to initially crush and decompose the waste solids that are more difficult to process, and then the high-speed grinding mechanism further refines and grinds the waste solids, thereby improving the processing quality of the kitchen waste solids, making it easier to decompose and decompose them into useful components, thereby completing the pollution-free, rapid and high-quality processing of the kitchen waste solids.
