Description

Technical Field

[0001] This utility model relates to the field of waste treatment equipment technology, and more specifically, to food waste treatment equipment. Background Technology

[0002] Food waste (or kitchen waste) is organic waste generated in daily life and catering services. It is characterized by its easy decomposition, high water content, and high organic matter content. It includes food scraps generated in households, catering businesses, canteens, and other settings, including raw food waste (fruit peels, vegetable leaves, etc.), cooked food scraps (leftovers), and food processing waste (oil, bone residue), etc. It contains a mixture of easily perishable organic matter and a large amount of liquid, making it difficult to handle.

[0003] In existing technologies, food waste treatment equipment generally uses composting (using aerobic fermentation technology to convert waste into organic fertilizer) or large anaerobic fermentation tanks (using anaerobic bacteria to produce biogas and organic fertilizer) to treat food waste. However, food waste is usually directly put into the fermentation or composting area for treatment. This food waste, which is mixed with large pieces of bones and large pieces of fruit peels and vegetable leaves, has a low decomposition efficiency, and the decomposition rate of various types of waste is uneven, which easily produces odors.

[0004] The currently published Chinese utility model patent, entitled "A Crushing Device for Food Waste Treatment" with publication number CN212237651U, includes a processing box with a lid hinged to the top. The top of the lid is threadedly connected to the top of the processing box, and two rubber pads are fixedly connected to the bottom of the lid. A first crushing box is fixedly connected to the top of the inner cavity of the processing box, and a discharge port is opened at the bottom of the first crushing box. A drive motor is also fixedly installed. This utility model can facilitate the separate crushing of soft waste such as fruit peels and vegetables and hard waste such as bones during the food waste treatment process.

[0005] Although this utility model can separate and crush food waste of different textures, thereby improving crushing efficiency, it requires the two types of food waste to be sorted in advance before crushing, which affects the processing efficiency of food waste. Moreover, it cannot further process the crushed food waste, which is prone to accumulating in the equipment for too long and producing odors. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] Example 1

[0050] Please refer to Figures 1-8 This utility model provides a food waste treatment device, including a collection bin 1, which is used to collect and store food waste for processing.

[0051] In the collection bin 1, from top to bottom, there are a crushing component 2, a chopping component 3, and a stirring component 5. The inlet of the collection bin 1 is located above the crushing component 2, and the outlet of the collection bin 1 is located below the stirring component 5.

[0052] In the process of food waste treatment, the food waste first falls into the crushing component 2 from the feed inlet. Since the food waste contains hard bones, fruit pits and animal shells, which are not easy to crush, the crushing component 2 is used first to quickly crush the hard blocks in the food waste, reducing the damage to the subsequent chopping component 3 caused by the excessively large hard blocks.

[0053] The crushing assembly 2 includes at least two crushing cylinders 203. The outer edges of adjacent crushing cylinders 203 are in rolling contact. The crushing cylinders 203 are connected to the rotating end of the rotating assembly and rotate. The adjacent crushing cylinders 203 rotate towards each other, so that when the food waste falls into the crushing cylinders 203, it is rolled downwards into the rotating crushing cylinders 203 while being crushed by the adjacent crushing cylinders 203.

[0054] In the food waste treatment process, the initially crushed food waste falls from the crushing component 2 into the chopping component 3. Since food waste contains relatively flexible fibrous waste such as fruit peels and vegetable leaves, some of the fibrous waste will basically remain in its original shape after crushing due to its flexibility. Therefore, the sharper chopping component 3 is used to rotate and chop the fibrous waste, reducing the proportion of large-volume waste in the food waste, increasing the number of small-particle waste in the food waste, and increasing the decomposition rate of the subsequent food waste.

[0055] The chopping component 3 includes a cutter 303, which is fixedly mounted on the upper part of the rotating shaft 302. The rotating shaft 302 is fixed on the motor 301. The cutter 303 rotates at high speed to cut and chop the falling fibrous waste. In the falling food waste, hard objects have already been crushed, so there will be no excessive collision with the blade of the cutter 303, thus maintaining the sharpness of the blade of the cutter 303.

[0056] A sieve plate 4 is also installed between the chopping component 3 and the agitation component 5. The sieve plate 4 is fixed inside the collection chamber 1 and has several through-holes. During the actual chopping process of the cutter 303, when there is an excessive amount of fibrous waste falling, the rotating cutter 303 cannot quickly chop all the fibrous waste. Therefore, the sieve plate 4 is used to retain and block the fibrous waste that has not been chopped in time, allowing it to be carried back into the chopping process by the rotating blades, thus improving the chopping quality of the chopping component 3. The long, through-holes on the sieve plate 4 reduce the occurrence of clogging, improving the passage efficiency of small particles and sticky waste (sticky waste such as sticky rice in food waste). It should be emphasized that, of course, due to the varying distribution direction of fibers, they may perfectly match the positions of the long slots. Therefore, the sieve plate may not be able to intercept all unchopped fibrous waste, but such fibrous waste is relatively small and can be ignored.

[0057] During the food waste treatment process, the food waste is shredded and flows through the screen plate 4 into the agitation component 5. The agitation component 5 is configured as a propeller blade, which is fixed to the lower part of the rotating shaft 302 and is electrically rotated by the motor 301. At this time, small particles, sticky waste, and stagnant liquid in the food waste mix together, forming a fluid state. The agitation component 5 then begins to agitate the fluid, uniformly mixing the various types of waste together. While the agitation component 5 is agitating, the heating component 7, which is fixed on the inner wall of the collection chamber 1, is powered on and heated (the heating component 7 is an electric heating plate, which is connected to an external power source via a circuit). This provides high-temperature sterilization of the agitated waste at 80-90℃, killing some pathogens and reducing the growth of pathogenic microorganisms.

[0058] After sterilization, turn off the heating component 7, and then add aerobic microbial agent into the collection bin 1 through the feed inlet (if the food waste in the collection bin 1 is too viscous, water can be added to dilute it and increase the humidity); then activate the ventilation component 6 at the bottom of the collection bin 1. The ventilation port of the ventilation component 6 is connected to the bottom of the collection bin 1, allowing air to enter the bottom of the collection bin 1, so that the food waste stirred in the collection bin 1 is always in an aerobic environment. In the aerobic, humid and warm (residual temperature after heating) environment, aerobic bacteria multiply rapidly, accelerate the decomposition of food waste rich in organic matter, and accelerate its decomposition into humus, thus reducing the food waste treatment cycle.

[0059] Example 2

[0060] To ensure the proper crushing of food waste by the crushing component 2, please refer to... Figures 2-4 In this embodiment, the compaction assembly 2 includes a protective shell 201, a compaction cylinder 203, a rotating assembly, a gear 205, a guide plate 206, and a sealing cover plate 207.

[0061] The rotating assembly includes a roller 202 and a motor 204.

[0062] Specifically, the protective shell 201 is fixedly installed on the top of the collection bin 1. The protective shell 201 is hollow inside and has a feed inlet at the top. The protective shell 201 is connected to the inside of the collection bin 1. Inside the protective shell 201, two rollers 202 are rotatably arranged in the same direction. A rolling cylinder 203 is coaxially fixed on the two rollers 202. The outer walls of the two rolling cylinders 203 roll in contact to achieve rolling rolling.

[0063] Of the two rollers 202, one roller 202 is coaxially fixed on the drive shaft of the motor 204, and the motor is fixed outside the collection bin 1. A gear 205 is also coaxially fixed on this roller 202. A gear 205 is also coaxially fixed on the other roller 202. The gears 205 on the two rollers 202 mesh with each other. Therefore, when the motor 204 drives one roller 202 to rotate, the other roller 202 will rotate through the gear 205, causing the two rollers 202 to rotate in opposite directions, thereby entraining and crushing the food waste.

[0064] The outer wall of the crushing cylinder 203 is uniformly fixed with protrusions. The surface of the protrusions is rounded and without sharp edges. When crushing is carried out, the protrusions on the outer walls of the two crushing cylinders 203 abut against each other. When the protrusions are in contact, a gap space is generated between the two crushing cylinders 203, which allows small particles or liquid waste to pass through quickly without being crushed, thus improving the throughput.

[0065] In addition, a guide plate 206 is fixedly installed inside the protective shell 201. The guide plate 206 is located above the crushing cylinder 203, and the guide end is located in the middle of the two crushing cylinders 203, so that the food waste is quickly guided to the crushing part.

[0066] Example 3

[0067] For quick shredding of various long, fibrous waste items, please refer to [link / reference]. Figures 3-5 In this embodiment, the chopping component 3 includes a motor 301, a rotating shaft 302, a cutter 303, and blades 304.

[0068] Specifically, motor 2 301 is fixed outside the collection bin 1. The drive shaft of motor 2 301 is coaxially fixedly connected to a rotating shaft 302. The rotating shaft 302 is vertically inserted inside the collection bin 1. Several cutters 303 are fixedly connected to the upper part of the rotating shaft 302. The cutters 303 are vertically and evenly arranged to form multiple layers of cutters 303, thereby increasing the cutting time of the cutters 303 on the falling food waste.

[0069] In addition, at least two sets of chopping components 3 are provided in the collection chamber 1. The two sets of chopping components 3 are symmetrically arranged below the crushing component 2, and the vertically arranged cutters 303 on the two sets of chopping components 3 are staggered, so that the food waste falling from above will be chopped by the two sets of chopping components 3 at the same time, thereby improving the chopping efficiency.

[0070] In addition, each blade of the cutter 303 is also fixedly provided with several teeth 304. The teeth 304 are evenly arranged on the outer edge of the blade, making the blade of the cutter 303 serrated. When the rotating cutter 303 comes into contact with the falling food waste, the teeth 304 can increase the frictional resistance of the cutter 303, making it easier to carry in the food waste. During the rotation, the serrated blade will also cut the fibrous waste while rubbing against the surface of the fibrous waste. By using cutting and severing to act on the fibrous waste at the same time, the cutting efficiency of the chopping component 3 is further improved. Example

[0071] When food waste is chopped, mixed, and then aerated to transform into humus, the humus will separate into solid and liquid phases in collection chamber 1 (the food waste will be left to stand after mixing). Solid humus will be deposited at the bottom of collection chamber 1, while liquid fertilizer will be located on top of the solid humus.

[0072] To facilitate the rapid collection of humus and liquid fertilizer, please refer to the following: Figure 2 , Figure 3 , Figure 7 and Figure 8 In this embodiment, the collection chamber 1 is connected to a discharge valve 9, which includes a solid discharge pipe 901, a first sealing valve 902, a second sealing valve 903, a filter screen 905, and an adsorption screen 906.

[0073] Specifically, the solid discharge pipe 901 is fixedly connected to the bottom of the collection chamber 1 and is used to output solid humic substances. The solid discharge pipe 901 is equipped with an openable and closable sealing valve 902. The liquid discharge pipe 903 is solidly connected to the lower side wall of the collection chamber 1 and is used to output liquid fertilizer. The liquid discharge pipe 903 is equipped with an openable and closable sealing valve 904.

[0074] Sealing valve 1 (902) and sealing valve 2 (904) are normally closed. After the food waste has fermented in collection chamber 1, sealing valve 2 (904) is opened first to allow most of the liquid fertilizer to be discharged and collected through liquid outlet pipe 903. When most of the liquid fertilizer has been collected, sealing valve 1 (902) is opened again to allow solid humic matter, along with a small amount of remaining liquid fertilizer, to be discharged and collected through solid outlet pipe 901. The reason for opening solid outlet pipe 901 last is to reduce the possibility of the liquid fertilizer level in collection chamber 1 dropping due to the initial discharge of solid humic matter, making it difficult to discharge through liquid outlet pipe 903.

[0075] It is worth noting that a filter screen 905 is fixedly covered in the liquid discharge pipe 903 to intercept the small amount of solid humus mixed in the liquid fertilizer and improve the solid-liquid separation rate.

[0076] Furthermore, in daily life, food waste generally contains a lot of grease, which is not easy to completely process in collection bin 1. Therefore, it will be mixed with the fermented liquid fertilizer. If the grease and liquid fertilizer are mixed and discharged, special cleaning work is required for the subsequent use of liquid fertilizer to reduce its impact on the soil fertilization process. However, processing after discharge is time-consuming and labor-intensive.

[0077] Therefore, it is worth noting that you should refer to [the relevant information]. Figure 6 An adsorption net 906 is also fixedly covered in the liquid discharge pipe 903. The adsorption net 906 is set as a sponge net that easily adsorbs oil, thereby reducing the oil content in the output liquid fertilizer and reducing the impact of oil on the liquid fertilizer.

[0078] Please refer to the following: Figure 6 The outer wall of the liquid discharge pipe 903 is also equipped with an openable sealing cover. The sealing cover is located at the corresponding position of the filter screen 905 and the adsorption screen 906. Since there are a lot of impurities and grease in the food waste, the filter screen 905 and the adsorption screen 906 need to be replaced regularly to maintain the filtration effect. When replacing, the locking sealing cover can be opened manually to quickly remove and replace the filter screen 905 and the adsorption screen 906.

[0079] Example 4

[0080] In order to achieve aeration and fermentation of food waste in collection chamber 1 and to ensure gas circulation within collection chamber 1, please refer to... Figure 7 and Figure 8 In this embodiment, the ventilation assembly 6 includes a jet nozzle 601, an air pipe 602, and an air pump 603.

[0081] Specifically, the jet head 601 is fixedly inserted at the bottom of the collection chamber 1, the jet nozzle of the jet head 601 is located inside the collection chamber 1, the jet head 601 is connected to the air pipe 602, the air pipe 602 is connected to the air pump 603, and the air pump 603 is fixed outside the collection chamber 1.

[0082] Among them, a number of jet heads 601 are evenly inserted at the bottom of the collection chamber 1, and all the jet heads 601 are connected to the same air pipe 602.

[0083] During the aeration of food waste in the collection chamber 1 by the ventilation component 6, the air pump 603 pumps air to each jet nozzle 601. The jet nozzles 601 introduce air into the collection chamber 1, providing an oxygen-rich environment for the food waste. This allows the aerobic bacteria added to the food waste to multiply rapidly and decompose the food waste. Each jet nozzle 601 is also equipped with a one-way valve, allowing air from the jet nozzle 601 to flow into the collection chamber 1 in only one direction. When aeration stops, the one-way valve automatically closes due to the lack of air pressure, sealing the air pipe 602 and reducing the possibility of food waste entering the air pipe 602 from the collection chamber.

[0084] In addition, the top of the collection chamber 1 is fixedly connected to the air outlet valve pipe 8, and the feed inlet of the protective shell 201 in the crushing assembly 2 is also provided with an openable and closable sealing cover 207, and an openable and closable valve is provided inside the air outlet valve pipe 8.

[0085] Because food waste is mostly organic matter, it is easy to emit odors and produce volatile gases (such as ammonia) when it decomposes naturally, which affects the surrounding environment. Therefore, it is necessary to treat the volatile gases and keep the inside of the collection chamber 1 ventilated to ensure smooth gas flow and maintain an oxygen-rich environment.

[0086] During the heating process, the feed inlet stops feeding, and the sealing cover 207 is manually covered to seal the feed inlet. The valve of the vent valve pipe 8 is also closed, forming a sealed space in the collection chamber 1, which reduces the degree of odor escape from the food waste during the heating and sterilization process.

[0087] During aeration, the feed inlet stops feeding, and the sealing cover 207 is manually closed to seal the feed inlet. The valve of the air outlet valve pipe 8 is opened, and the air introduced from the bottom of the collection chamber 1 by the ventilation component 6 will be output from the air outlet valve pipe 8 to achieve air circulation.

[0088] An adsorption net 906 is also installed inside the outlet valve pipe 8. The adsorption net 906 here is an activated carbon cotton net, which uses activated carbon to adsorb ammonia and other gases, thereby reducing the harmfulness of the output gas.

[0089] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description. The scope of this utility model is defined by the appended claims.
