Description

Technical Field

[0001] The present invention relates to the field of food waste treatment, and in particular to a kitchen waste treatment device. Background Art

[0002] After people have meals, they generally generate various kitchen wastes, which must be processed in real time. Otherwise, it is easy to breed germs or cause a large number of cockroaches and mice to reproduce, not only causing environmental pollution, but also being harmful to human health. Therefore, based on the needs of environmental protection and health, for such kitchen wastes, generally in addition to using the method of food classification for cleaning, at present, a food waste processor is mainly installed at the bottom of the kitchen sink. The food waste processor stirs the downward flowing kitchen waste and crushes it into slag with a size of about 0.5 cm to 1 cm, and discharges it into the sewer pipe for subsequent treatment.

[0003] However, for areas where the infrastructure has not been constructed perfectly, the kitchen waste directly discharged into the sewer pipe not only fails to meet the requirements of environmental protection, but will bring greater disasters to the environment. Since the specific gravity of the shredded kitchen waste is greater than that of water, after the kitchen waste is shredded into small pieces or mud, due to the relatively gentle water flow velocity in the sewer pipe, the kitchen waste cannot be effectively flushed. The kitchen waste will gradually accumulate upward at the bottom of the sewer pipe, resulting in the inability of the water flow and the kitchen waste to flow smoothly through the sewer pipe, accelerating the blocking speed of the sewer pipe. And if the kitchen waste and sludge remaining in the sewer pipe are not cleaned regularly, when there is a large amount of rainfall, it is easy for the muddy water containing residues to overflow from the drain outlet of the sewer pipe, causing secondary environmental pollution.

[0004] Regarding the problem that kitchen waste in the related technology cannot be fully processed and collected, and is easy to cause environmental pollution, no effective solution has been given yet.

[0005] Therefore, based on the experience and practice of the inventor in the related industry for many years, a kitchen waste treatment device is proposed to overcome the defects of the prior art. Summary of the Invention

[0060] As Figures 1 to 7 shown, the present invention provides a kitchen waste treatment device, which includes a drying and stirring mechanism 3, a crushing mechanism 5, a material leakage mechanism 4, and a deodorizing mechanism 6. The drying and stirring mechanism 3 is used for synchronously drying and stirring kitchen waste. The crushing mechanism 5 is used for crushing the dried and stirred kitchen waste. The material leakage mechanism 4 is used to control the amount of kitchen waste transported from the drying and stirring mechanism to the crushing mechanism. The deodorizing mechanism 6 is used to deodorize the odor-containing gas generated during the stirring and drying process of kitchen waste. Among them: a residue inlet communicating with the inside of the drying and stirring mechanism 3 is provided at the top of the drying and stirring mechanism 3, a residue outlet communicating with the inside of the drying and stirring mechanism 3 is provided at the bottom of the drying and stirring mechanism 3, a residue inlet communicating with the inside of the crushing mechanism 5 is provided at the top of the crushing mechanism 5, a crushed slag outlet communicating with the inside of the crushing mechanism 5 is provided at the bottom of the crushing mechanism 5. The residue inlet of the drying and stirring mechanism 3 is connected to the deodorizing mechanism 6, the material outlet of the drying and stirring mechanism 3 is connected to the residue inlet of the crushing mechanism 5. The material leakage mechanism 4 is disposed between the material outlet of the drying and stirring mechanism 3 and the residue inlet of the crushing mechanism 5 in an openable and closable manner to control the amount of kitchen waste transported from the drying and stirring mechanism 3 to the crushing mechanism 5. An aggregate bin 7 is provided below the crushed slag outlet of the crushing mechanism 5.

[0061] In the present invention, kitchen waste enters the drying and stirring mechanism 3 through the residue inlet of the drying and stirring mechanism 3. While stirring the kitchen waste, the drying and stirring mechanism 3 heats and dries the kitchen waste. The odoriferous gas generated by the kitchen waste enters the deodorizing mechanism 6 through the residue inlet of the drying and stirring mechanism 3. After the deodorizing mechanism 6 deodorizes the odoriferous gas, it can be directly discharged to the outside. The dried kitchen waste then enters the pulverizing mechanism 5 through the material outlet of the drying and stirring mechanism 3 and the residue inlet of the pulverizing mechanism 5 in sequence. The pulverizing mechanism 5 pulverizes the kitchen waste. After the kitchen waste is fully pulverized, it can be discharged into the aggregate bin 7 for centralized collection. The pulverized residue of the kitchen waste collected in the aggregate bin 7 can be directly used as fertilizer, which can not only improve the utilization rate of kitchen waste, avoid the waste of available resources, but also effectively prevent the pollution of the environment by kitchen waste. The structure of the present invention is simple and easy to operate, and it can stir, dry, deodorize, pulverize and collect kitchen waste in sequence, achieving the purpose of fully treating kitchen waste and being suitable for large-scale promotion and use. In addition, the leakage prevention mechanism 4 controls the amount of kitchen waste transported from the drying and stirring mechanism 3 to the pulverizing mechanism 5, ensuring that the pulverizing mechanism 5 can fully pulverize the kitchen waste entering it and improving the treatment effect of kitchen waste.

[0062] Further, as Figure 1 , Figure 2 shown, the kitchen waste treatment device further includes a housing 1 and a top cover 2. The housing 1 is a cuboid structure arranged vertically. An accommodation chamber 101 is provided inside the housing 1. The drying and stirring mechanism 3, the pulverizing mechanism 5, the leakage prevention mechanism 4 and the deodorizing mechanism 6 are all fixedly arranged in the accommodation chamber 101. A feeding port 104 is opened at the middle position of the top of the housing 1. The feeding port 104 is connected to the residue inlet of the drying and stirring mechanism 3. The top cover 2 is arranged on the top of the housing 1. One side edge of the top cover 2 is hinged to one side edge of the top of the housing 1, so that the top cover 2 can open and block the feeding port 104.

[0063] Further, as Figure 1 , Figure 2 , Figure 7 shown, the aggregate bin 7 is a rectangular box body with an open top and a sealed bottom. The top opening of the aggregate bin 7 is located directly below the pulverized residue outlet of the pulverizing mechanism 5 to ensure that the pulverized residue of the kitchen waste discharged from the pulverized residue outlet of the pulverizing mechanism 5 can directly fall into the aggregate bin 7.

[0064] Further, as Figure 2 shown, a push-pull port 105 communicating with the accommodation chamber 101 is opened on the bottom side wall of the housing 1. The aggregate bin 7 is slidably arranged at the push-pull port 105 and can slide through the push-pull port 105 into the accommodation chamber 101, facilitating the removal and recycling of the pulverized residue of the kitchen waste in the aggregate bin 7.

[0065] Further, as Figure 2 shown, a push-pull handle 701 is provided on the side wall of the aggregate bin 7 located outside the outer shell 1.

[0066] In an alternative embodiment of the present invention, as Figure 1 shown, the deodorizing mechanism 6 includes a first air duct 601 and a second air duct 602. The first air duct 601 is horizontally arranged in the top cover 2, and the second air duct 602 is vertically arranged in the accommodating chamber 101. A first air outlet 202 and a first air inlet 201 communicating with the residue inlet of the drying and stirring mechanism 3 are provided on the top cover 2. A second air inlet 102 communicating with the accommodating chamber 101 is provided at the top of the outer shell 1, and a second air outlet 103 communicating with the accommodating chamber 101 is provided on the side wall of the outer shell 1. One end of the first air duct 601 is connected to the first air inlet 201, and the other end of the first air duct 601 is connected to the first air outlet 202. One end of the second air duct 602 is connected to the second air inlet 102, and the other end of the second air duct 602 is connected to the second air outlet 103. A deodorizing device is provided in the first air duct 601 and / or the second air duct 602. The odor-containing gas generated by the kitchen waste in the drying and stirring mechanism 3 enters the first air duct 601 from the residue inlet of the drying and stirring mechanism 3. During the process of passing through the first air duct 601 and the second air duct 602 in sequence, the deodorizing device deodorizes the gas, and the purified gas is directly discharged to the outside through the second air outlet 103 on the outer shell 1.

[0067] Further, the deodorizing device can be, but is not limited to, an activated carbon adsorbent provided in the first air duct 601 and / or the second air duct 602.

[0068] In an alternative embodiment of the present invention, as Figure 1 、 Figure 3 、 Figure 7As shown in the figure, the drying and stirring mechanism 3 includes a stirring bin 301, a stirring motor 302, a stirring shaft 303 and a heating pipe 304. The stirring bin 301 is a cylindrical structure arranged in the vertical direction. A stirring bin inlet 3011 communicating with the inside of the stirring bin 301 is provided at the top of the stirring bin 301, and a stirring bin outlet 3012 communicating with the inside of the stirring bin 301 is provided at the bottom of the stirring bin 301. The stirring motor 302 is fixedly installed on the outer wall of the bottom of the stirring bin 301, and the motor shaft of the stirring motor 302 extends into the lower part inside the stirring bin 301. The middle part of the stirring shaft 303 is connected to the motor shaft of the stirring motor 302 located inside the stirring bin 301. The heating pipe 304 is fixedly arranged on the outer wall of the lower part of the stirring bin 301 along the circumferential direction of the stirring bin 301. Among them, the stirring bin inlet 3011 is the residue inlet of the drying and stirring mechanism 3, and the stirring bin outlet 3012 is the residue outlet of the drying and stirring mechanism 3. The stirring motor 302 drives the stirring shaft 303 to rotate, so as to stir the kitchen waste in the stirring bin 301. At the same time, the kitchen waste in the stirring state is heated and dried by the heating pipe 304.

[0070] In this embodiment, as Figure 3 shown, a temperature and humidity sensor 305 is arranged on the side wall of the stirring bin 301. The temperature and humidity inside the stirring bin 301 are detected in real time through the temperature and humidity sensor 305 to ensure that the kitchen waste can be fully dried. When the temperature and humidity inside the stirring bin 301 reach the preset values, the leakage mechanism 4 can be opened to convey the kitchen waste in the drying and stirring mechanism 3 into the crushing mechanism 5.

[0071] Specifically, as Figure 4 shown, a first threaded hole 3031 is provided at the middle position of the stirring shaft 303, and an external thread matching the first threaded hole 3031 is arranged on the motor shaft of the stirring motor 302.

One end of the first stirring rod 3033 is connected to one end of the second stirring rod 3032, and the other ends of the first stirring rod 3033 and the second stirring rod 3032 respectively extend towards the inner walls of two opposite sides of the stirring bin 301. Through the arrangement of the first stirring rod 3033 and the second stirring rod 3032, the stirring range of the kitchen waste is increased, making the stirring of the kitchen waste more sufficient.

[0072] Further, a support rib 3034 is arranged at the bottom of the second stirring rod 3032 along the length direction of the second stirring rod 3032. The top of the support rib 3034 is connected to the bottom of the second stirring rod 3032, and the bottom of the support rib 3034 abuts against the inner wall of the bottom of the stirring bin 301. The stability of the installation of the stirring shaft 303 in the stirring bin 301 is improved by the arrangement of the support rib 3034.

The central position of the grinding disc 502 is connected to the motor shaft of the crushing motor 503 located in the crushing bin 501. Among them, the feeding hopper inlet is the residue inlet of the crushing mechanism 5, and the crushing bin outlet is the crushed residue outlet of the crushing mechanism 5. The crushing motor 503 drives the grinding disc 502 to rotate, so as to crush the kitchen waste.

[0075] Further, as Figure 5 shown, the grinding disc 502 is a disc-shaped structure arranged horizontally. The grinding disc 502 is arranged at the upper part of the crushing bin 501.

The slider driving motor 403 drives the slider 402 to move forward and backward along the length direction of the mounting bracket 401, thereby controlling the time when the first material leakage port 4014 is connected and staggered with the second material leakage port 4024, thereby controlling the amount of kitchen waste transported from the drying and stirring mechanism to the crushing mechanism.

[0079] Specifically, Figure 6As shown, the mounting bracket 401 includes a horizontal mounting plate 4011 and a vertical mounting plate 4012.

After the deodorizing mechanism 6 deodorizes the odoriferous gas, it can be directly discharged to the outside. When the temperature value and humidity value collected by the temperature and humidity sensor 305 reach the preset values (that is, the kitchen waste is fully dried), the material leakage mechanism 4 is controlled to open, and the dried kitchen waste in the drying and stirring mechanism 3 is conveyed to the crushing mechanism 5. The crushing mechanism 5 crushes the kitchen waste. After the kitchen waste is fully crushed, it can be discharged into the aggregate bin 7 for centralized collection, completing the treatment of the kitchen waste.

[0086] Second, the kitchen waste treatment device centrally collects the kitchen waste after drying and fully crushing it through the aggregate bin 7. The crushed residue of the kitchen waste collected in the aggregate bin 7 can be directly used as fertilizer, which can not only improve the utilization rate of kitchen waste, avoid the waste of available resources, but also effectively prevent the pollution of the environment by kitchen waste.

[0087] III. A material leakage mechanism 4 that can be opened and closed is provided between the material outlet of the drying and stirring mechanism 3 and the residue inlet of the crushing mechanism 5 in the food waste treatment device. The food waste quantity conveyed from the drying and stirring mechanism 3 to the crushing mechanism 5 is controlled through the material leakage mechanism 4 to ensure that the crushing mechanism 5 can fully crush the food waste entering it and improve the treatment effect of the food waste.
