Description

Technical Field

[0001] The present invention relates to the technical field of kitchen waste recycling, and particularly relates to a kitchen waste resource recycling and treatment device. Background Art

[0002] Kitchen waste refers to food residues and kitchen garbage generated in daily life, such as leftover food, fruit peels, and vegetable leaves. If these wastes are not properly treated, they will pollute the environment. At present, kitchen waste is usually used as raw material, and through resource recycling and treatment technology, by means of aerobic composting, these wastes are converted into valuable compost products. This treatment method not only reduces the environmental pollution caused by kitchen waste, but also realizes the recycling of resources, with significant environmental and economic benefits.

[0003] In the prior art, when aerobic composting treatment is carried out on kitchen waste, the shredded kitchen waste is mixed with a conditioner (such as straw, rice husk, etc.) in a certain proportion to improve the aeration and water retention of the compost. Then it is put into a fermentation tank, and oxygen is provided by turning the pile or forced ventilation to maintain aerobic conditions. Under aerobic conditions, microorganisms will degrade organic matter and generate high temperature, killing pathogenic bacteria and weed seeds. As the easily degradable organic matter is consumed, the temperature of the pile gradually decreases, and mesophilic microorganisms become dominant again, continuing to decompose the remaining organic matter. Finally, the temperature of the pile approaches the ambient temperature, and the organic matter is converted into stable humus, and the compost product meets the requirements of harmlessness and stabilization.

[0004] However, in the actual application process, due to the certain adhesiveness of kitchen waste, when the fermentation is completed, some waste will adhere to the inner wall of the fermentation tank and needs to be cleaned manually at regular intervals.

[0025] Advantages of the present invention:

[0026] (1) During the fermentation of kitchen waste by the present invention, the rotating module drives the sleeve and the support rod to rotate in the fermentation tank. During the rotation of the sleeve and the support rod, the first stirring blade and the second stirring blade can be synchronously driven to rotate, so as to stir the waste in the fermentation tank, improve the contact effect between the waste and oxygen, avoid the situation that some waste accumulated at the bottom of the fermentation tank cannot contact with oxygen, and make the waste fermentation more sufficient.

[0027] (2) The present invention fixedly arranges a baffle for embedding in the chute on one side of the second stirring blade. When the rotating module drives the sleeve to rotate, based on the arrangement of the baffle and the chute, the sleeve can be synchronously driven to rotate. Correspondingly, when the support rod is driven to rotate, the sleeve can be synchronously driven to rotate. The present invention does not need to set two servo driving parts to synchronously drive the sleeve and the support rod to rotate respectively, which not only reduces the cost, but also has higher synchronism and stability;

[0028] (3) When discharging by the present invention, as the nut drives the two sealing plates to move away from each other, the sealing plates drive the two limiting frames to approach each other synchronously through the first rack, the gear and the second rack. The limiting frames drive the two circular plates to approach each other through the driving rod. The present invention does not need to adopt other servo driving devices to adjust the positions of the two circular plates. During discharging, the effect of automatically adjusting the two circular plates to approach each other can be achieved, which not only saves the cost, but also improves the synchronism and stability.

Detailed implementation manners

[0039] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0040] Embodiment 1

[0041] Please refer to Figures 1 - 2 As shown, the present invention is a resource recovery and treatment device for kitchen waste, including a fermentation tank 1, and a feeding port 101 is provided on the fermentation tank 1; specifically, a sealing door 102 is rotatably arranged at the feeding port 101 for closing the feeding port 101. When fermenting kitchen waste, the sealing door 102 is opened, and the waste can be added into the fermentation tank 1 through the feeding port 101.

[0042] Please refer to Figure 3 , a discharge groove 103 is provided at the bottom of the fermentation tank 1, and two groups of sealing plates 104 are symmetrically and slidably arranged in the discharge groove 103, and the two side sealing plates 104 are connected to an adjustment module that drives them to approach or separate from each other; specifically, in the initial state, the two groups of sealing plates 104 are in a state of being mutually attached (refer to Figure 7 ) to seal the discharge groove 103. When the kitchen waste is put into the fermentation tank 1, the waste will not be discharged through the discharge groove 103. Correspondingly, after fermentation is completed, the two side sealing plates 104 are driven by the adjustment module to separate from each other to form a discharge port between the two side sealing plates 104 (refer to Figure 8 ), so that the fermented kitchen waste is discharged through the discharge port.

[0043] Please refer to Figure 4 And Figure 6, a sleeve 6 is rotatably arranged on one side in the fermentation tank 1, and a group of first stirring blades 209 are fixedly arranged on the sleeve 6. A support rod 602 is rotatably arranged at the other end in the fermentation tank 1. The support rod 602 is slidably inserted into the sleeve 6. A group of second stirring blades 603 are fixedly arranged on the support rod 602. The ends of the first stirring blades 209 and the second stirring blades 603 away from the axis are slidably attached to the inner wall of the fermentation tank 1. Among them, a rotation module is also arranged outside the fermentation tank 1, and the rotation module is used to drive the sleeve 6 and the support rod 602 to rotate in the fermentation tank 1. It can be explained that during the fermentation process of food waste in this embodiment, the rotation module is used to drive the sleeve 6 and the support rod 602 to rotate in the fermentation tank 1. During the rotation of the sleeve 6 and the support rod 602, the first stirring blades 209 and the second stirring blades 603 can be driven to rotate synchronously, so as to stir the waste in the fermentation tank 1, improve the contact effect between the waste and oxygen, and avoid the situation that some waste accumulated at the bottom of the fermentation tank 1 cannot contact oxygen, making the waste fermentation more sufficient. At the same time, during the rotation of the stirring blades, the waste adhered to the inner wall of the fermentation tank 1 can be scraped off. During discharging, the stirring blades can rotate synchronously, and the scraped waste falls along the discharge port. When the fermentation tank 1 of this embodiment is in use, it is not necessary to clean the tank body manually at regular intervals, and the continuous treatment effect of food waste can be achieved.

[0044] Embodiment 2

[0045] On the basis of Embodiment 1, please refer to Figure 1 、 Figure 4 and Figure 6 , the fermentation tank 1 is a hollow structure with openings at both ends. Among them, a first circular plate 201 is slidably embedded at the opening of one end of the fermentation tank 1, and the sleeve 6 is fixed at the center end of the first circular plate 201. A second circular plate 2 is slidably embedded at the opening of the other end, and the support rod 602 is fixed at the center end of the second circular plate 2. A driving module is also arranged outside the fermentation tank 1, and the driving module is used to drive the first circular plate 201 and the second circular plate 2 to approach or separate from each other. It can be explained that in the actual application process, as the fermentation is completed, the adjustment module is used to drive the two side sealing plates 104 to separate from each other to form a discharge port between the two side sealing plates 104. Since the opening length of the discharge port is less than the length of the fermentation tank 1, some waste will stay on both sides in the fermentation tank 1. In order to scrape off all this waste, in this embodiment, the driving module can be used to drive the first circular plate 201 and the second circular plate 2 to approach each other. During the approaching process, the circular plates scrape the waste staying in the tank body towards the discharge port until the circular plates move to the discharge port and stop, and then all the waste can be scraped off.

[0046] It can be referred to Figure 6, in this embodiment, as the driving module drives the first circular plate 201 and the second circular plate 2 to approach each other, in order to avoid interference between the second stirring blade 603 and the sleeve 6, a sliding groove 604 for embedding the second stirring blade 603 is formed on the barrel wall of the sleeve 6; specifically, as the first circular plate 201 and the second circular plate 2 approach each other, while the support rod 602 is embedded in the sleeve 6, it drives the second stirring blade 603 to move along the sliding groove 604, thereby avoiding interference between components.

[0047] Furthermore, since the sliding groove 604 communicates with the inside of the sleeve 6, in order to prevent waste from entering the sleeve 6 through the sliding groove 604 during the fermentation process, in this embodiment, a baffle 605 fixed to the second stirring blade 603 is slidably embedded in the sliding groove 604, and a guiding groove 601 for embedding the baffle 605 is formed on the first circular plate 201; it can be explained that in the initial state, the baffle 605 is in a state of sealing the sliding groove 604, and waste cannot enter the sleeve 6 along the sliding groove 604. As the second stirring blade 603 slides along the sliding groove 604, the second stirring blade 603 can synchronously drive the baffle 605 to slide along the guiding groove 601, and the other end of the baffle 605 can extend through the guiding groove 601 to the outside of the fermentation tank 1. During the entire movement process, it is always in a state of sealing the sliding groove 604.

[0048] In addition, it should also be noted that in this embodiment, by fixedly arranging a baffle 605 for embedding the sliding groove 604 on one side of the second stirring blade 603, when the rotating module drives the sleeve 6 to rotate, based on the arrangement of the baffle 605 and the sliding groove 604, the sleeve 6 can be synchronously driven to rotate. Correspondingly, when the support rod 602 is driven to rotate, the sleeve 6 can be synchronously driven to rotate. In this embodiment, it is not necessary to set two sets of servo driving components to synchronously drive the sleeve 6 and the support rod 602 to rotate respectively, which not only reduces the cost, but also has higher synchronism and stability.

[0049] It can be referred to Figures 1 - 2 , the fermentation tank 1 is fixed on the support frame 4, the adjusting module includes a screw rod 402 rotatably arranged on the support frame 4, and a first motor 401 for driving the screw rod 402 to rotate is also fixed on the support frame 4. The thread directions on both sides of the screw rod 402 are opposite, and nuts 403 are symmetrically spirally sleeved on the screw rod 402, and the two nuts 403 are respectively fixed to the sealing plate 104 through brackets; it can be explained that in this embodiment, the first motor 401 can first drive the screw rod 402 to rotate, and during the movement of the nut 403 on the screw rod 402, the two sealing plates 104 can be driven to approach or separate from each other through the brackets, thereby realizing the discharging process of the fermented product.

[0050] In this embodiment, the driving module includes a first rack 502 fixed to one side of the sealing plate 104. A gear 501 is arranged on the first rack 502. The gear 501 is rotatably connected to a bracket fixed to the support frame 4. The first rack 502 meshes with the gear 501. The driving module includes a driving rod 205 fixed to the outer sides of the first circular plate 201 and the second circular plate 2. The other end of the driving rod 205 is rotatably connected to the limiting frame 206. Among them, a second rack 5 meshing with the gear 501 is fixedly arranged at the bottom of the limiting frame 206. The first rack 502 and the second rack 5 are arranged on both sides of the gear 501 in a parallel and offset manner. It can be explained that during blanking, as the nut 403 drives the two sealing plates 104 to move away from each other, the sealing plate 104 synchronously drives the two limiting frames 206 to approach each other through the first rack 502, the gear 501 and the second rack 5. The limiting frame 206 drives the two circular plates to approach each other through the driving rod 205. In this embodiment, there is no need to use other servo driving devices to adjust the positions of the two circular plates. During blanking, the effect of automatically adjusting the two circular plates to approach each other can be achieved, which not only saves costs but also improves the synchronism and stability.

[0051] In addition, in order to improve the stability of the movement of the circular plate, reference can be made to Figure 2 , retaining frames 207 are fixedly arranged at the two open ends of the fermentation tank 1. Guide rods 208 slidably connected to the limiting frame 206 are fixedly arranged on the retaining frames 207. Specifically, the limiting frame 206 can slide synchronously on the guide rod 208 during movement to improve its stability during movement.

[0052] Reference can be made to Figures 1 - 2 and Figure 4 , the rotation module includes a second motor 404 fixed to one of the limiting frames 206. The driving end of the second motor 404 is fixed to the driving rod 205. It can be explained that during fermentation, the driving rod 205 can be driven to rotate by the second motor 404. The driving rod 205 can drive one circular plate to rotate, and then drive the stirring blades to rotate through the support rod 602 and the sleeve 6.

[0053] Reference can be made to Figure 2 , a blower 203 is fixedly arranged on one side of the bottom of the support frame 4. The blower 203 is communicated with the air holes opened on the first circular plate 201 through an air duct 202. Air holes are opened on the second circular plate 2, and an air vent valve 204 is arranged at the air holes. It can be explained that during the aerobic fermentation of kitchen waste in this embodiment, air can be sent into the fermentation tank 1 through the blower 203 and the air duct 202. Opening the air vent valve 204 can conduct ventilation to increase the oxygen content in the fermentation tank 1, making the fermentation efficiency higher and the fermentation effect better.

[0054] Reference can be made to Figures 1 - 2 and Figure 5, a conveyor belt 3 is provided at the bottom of the fermentation tank 1. The width of the conveyor belt 3 is the same as the opening width of the discharge port. Partition plates 301 are fixedly arranged on both sides of the conveyor belt 3. The end of the conveyor belt 3 is set as the discharging end 302, and a positioning plate 306 is arranged at the end of the discharging end 302. It can be explained that after fermentation, the waste is discharged onto the conveyor belt 3 through the discharge port and is limited by the partition plates 301 and the positioning plate 306 to avoid the phenomenon of waste falling. The conveyor belt 3 can discharge the waste to the discharging end 302 for discharging, so as to facilitate subsequent unified treatment.

[0055] Specifically, reserved openings 303 are opened on both sides of the discharging end 302. A push plate 304 is slidably embedded at one of the reserved openings 303, and the push plate 304 is fixed to the driving end of the pushing cylinder 305. It can be explained that when the discharged waste is conveyed to the discharging end 302, the pushing cylinder 305 is turned on, and the pushing cylinder 305 pushes the waste at the discharging end 302 along the reserved opening 303 to the next process through the push plate 304, so as to facilitate subsequent unified treatment.

[0056] A recycling method for a kitchen waste resource recycling and treatment device includes the following steps:

[0057] Please refer to Figures 1 - 4 , open the sealing door 102, add waste into the fermentation tank 1 through the feeding port 101, and close the sealing door 102;

[0058] During the fermentation process, air is sent into the fermentation tank 1 through the blower 203 and the air duct 202, and the ventilation valve 204 is opened for ventilation;

[0059] Please refer to Figure 6 , drive the sleeve 6 and the support rod 602 to rotate in the fermentation tank 1 through the rotation module. During the rotation of the sleeve 6 and the support rod 602, the first stirring blade 209 and the second stirring blade 603 can be synchronously driven to rotate, and the waste in the fermentation tank 1 is stirred;

[0060] During discharging, the stirring blades can rotate synchronously. The two side sealing plates 104 are driven to separate from each other through the adjustment module to form a discharge port between the two side sealing plates 104 (please refer to Figure 8 ), so that the kitchen waste after fermentation is discharged through the discharge port.
