Description

Technical Field

[0001] The invention relates to the technical field of food waste fermentation treatment equipment, and in particular to food waste fermentation treatment equipment and a treatment method thereof. Background Art

[0002] With the continuous growth of population and the improvement of living standards, especially in cities, domestic garbage has increased rapidly. At present, domestic garbage in large, medium and small towns has become a very serious problem. There are mountains of garbage concentration points in cities and garbage dumps scattered in living areas. Garbage is divided into domestic garbage, restaurant garbage and food waste according to its source. Among them, organic waste in restaurant garbage is also called organic waste in the catering industry. It is mainly a mixture of leftovers, scraps, expired food, etc. generated in the operation process of hotels, restaurants, restaurants, canteens of enterprises and institutions, etc., with the characteristics of large quantity and wide range. And restaurant garbage has the characteristics of different composition and properties from ordinary domestic garbage, such as high water content, heavy oil and high salt content, and the above characteristics of restaurant garbage in domestic restaurants, restaurants and canteens are more obvious, and there is a significant difference from non-Chinese restaurant garbage. Therefore, my country's restaurant garbage has the characteristics of easy corruption (corruption occurs after being placed for a few hours) and serious environmental pollution. At present, the main methods of garbage disposal in countries around the world include landfill, incineration and composting.

[0003] In the process of composting, food waste fermentation treatment equipment is needed. The food waste fermentation treatment equipment under the existing technology needs to add fermentation bacteria when fermenting food waste. Due to the different volumes of various food wastes, the fermentation time of food waste is usually determined by larger pieces of food waste, which will make the fermentation time long and the efficiency low. Therefore, the food waste needs to be crushed into small pieces of uniform size before fermentation. Summary of the invention

[0007] The crushing mechanism comprises a crushing shaft fixedly connected to the output end of the driving motor, and a plurality of crushing blades are fixedly connected to one end of the crushing shaft away from the driving motor, and the crushing blades are arranged in a spiral shape as a whole.

[0008] Furthermore, a grading and screening mechanism is arranged inside the crushing cover, and the grading and screening mechanism includes a conveying blade fixedly connected to the crushing shaft. A first arc-shaped screen plate is fixedly connected to the bottom of the crushing cover, and a plurality of grading screen holes are opened on the first arc-shaped screen plate, and the grading screen holes gradually become larger from right to left.

[0009] Furthermore, a transmission mechanism is arranged directly below the crushing shaft, and the transmission mechanism includes a transmission disc 1 fixedly connected to one end of the crushing shaft close to the driving motor, a transmission belt is transmission-connected to the transmission disc 1, a side wall of the connecting plate is rotationally connected to a rotating shaft, a transmission disc 2 is fixedly connected to the rotating shaft, and an end of the transmission belt away from the transmission disc 1 is transmission-connected to the transmission disc 2.

[0010] Furthermore, the transmission mechanism also includes a gear fixedly connected to the end of the rotating shaft away from the connecting plate. Both ends of the crushing cover are fixedly connected to limit rings. The limit ring is rotatably connected to a gear ring inside, and the gear ring is meshed with the gear.

[0011] Furthermore, a crushing mechanism is arranged inside the crushing cover, and the crushing mechanism includes a plurality of connecting columns fixedly connected to the gear ring, and a spiral rolling plate is fixedly connected to one end of the connecting column away from the gear ring, and a plurality of rolling grooves are opened on one side of the spiral rolling plate.

[0012] Furthermore, the crushing mechanism also includes a plurality of fixed blocks fixedly connected to the inner wall of the crushing cover, one end of the fixed block away from the inner wall of the crushing cover is rotatably connected to a rotating shaft, a passive rolling plate is fixedly connected to the rotating shaft, a plurality of rolling grooves are opened on one side of the passive rolling plate, a plurality of arc springs are fixedly connected to the side of the passive rolling plate away from the rolling grooves, and one end of the arc spring away from the passive rolling plate is fixedly connected to the inner wall of the crushing cover.

[0013] Furthermore, a vibrating screen mechanism is provided at the bottom of the crushing cover, and the vibrating screen mechanism includes a plurality of fixed arc blocks fixedly connected to the bottom of the crushing cover, a vibrating screen plate is slidably connected inside the fixed arc block, a sliding column is slidably connected inside the fixed arc block, the sliding column runs through both ends of the vibrating screen plate and is fixedly connected to the vibrating screen plate, a vibrating spring is sleeved on the sliding column, the vibrating spring is fixedly connected to the fixed arc block, a passive extrusion block is fixedly connected to one end of the sliding column away from the vibrating spring, and active extrusion blocks are fixedly connected to both ends of the spiral rolling plate.

[0014] The processing method of the food waste fermentation processing equipment comprises the following steps:

[0015] S1: Preliminary screening. Several crushing blades will transport the preliminarily crushed food waste to the vicinity of the conveying blades. The crushing shaft drives the conveying blades to rotate at the same time. The conveying blades rotate to transport the preliminarily crushed food waste near the crushing shaft forward along the crushing cover. At this time, the food waste inside the crushing cover will be screened through the graded sieve holes on the first curved sieve plate;

[0016] S2: Crushing process: the rotation of the spiral rolling plate will drive the larger pieces of food waste inside the crushing cover to rotate. Under the action of centrifugal force, the food waste will move to the crushing groove of the spiral rolling plate. When the spiral rolling plate and the passive rolling plate are squeezed, the crushing groove on the spiral rolling plate will cooperate with the crushing groove on the passive rolling plate to further crush the food waste on the spiral rolling plate.

[0017] S3: Vibration screening. The active extrusion block is squeezed with the passive extrusion block on the top of the sliding column. The passive extrusion block drives the sliding column to move downward rapidly. The sliding column moves downward rapidly and drives the vibration screen plate fixedly connected to the sliding column to move downward along the slide groove in the fixed arc block. When the active extrusion block and the passive extrusion block are squeezed, under the pulling force of the sliding column, the vibration spring drives the vibration screen plate on the sliding column to rebound quickly, accelerating the passage of the food waste on the vibration screen plate through the vibration screen plate, avoiding a large amount of food waste from clogging the vibration screen plate, and improving the working stability of the device.

[0018] The present invention has the following beneficial effects:

[0019] (1) In the present invention, the rotation of the spiral rolling plate will drive the larger pieces of food waste inside the crushing cover to rotate. Under the action of centrifugal force, the food waste will move to the crushing groove of the spiral rolling plate. When the spiral rolling plate and the passive rolling plate are squeezed, the crushing groove on the spiral rolling plate will cooperate with the crushing groove on the passive rolling plate to further crush the food waste on the spiral rolling plate. Since the spiral rolling plate is arranged in a spiral shape, during the crushing process, the spiral rolling plate will transport the crushed food waste to the right end of the spiral rolling plate. Since the food waste on the left side is larger in volume, the longer the crushing distance of the food waste on the left side is, the longer the crushing time is. This arrangement is conducive to improving the crushing efficiency of the crushing mechanism. At the same time, the food waste near the right side of the crushing cover is smaller in volume, so the food waste near the right side of the crushing cover will quickly pass through the vibrating screen plate into the fermentation box, thereby improving the screening efficiency of the vibrating screen mechanism.

[0020] (2) In the present invention, when the food waste fermentation treatment equipment is used, the dehydrated food waste is first poured into the crushing cover through the feed port. At this time, the driving motor is started, and the output end of the driving motor rotates to drive the crushing shaft to rotate. The crushing shaft rotates to drive the crushing blades to rotate. At this time, the rotating crushing blades initially crush the food waste in the crushing cover. Because the plurality of crushing shafts are arranged in a spiral shape, the plurality of crushing blades will convey the initially crushed food waste to the vicinity of the conveying blades. The crushing shaft drives the conveying blades to rotate at the same time. The conveying blades rotate to convey the initially crushed food waste near the crushing shaft forward along the crushing cover. At this time, the food waste in the crushing cover will be screened through the graded sieve holes on the first arc-shaped sieve plate. Because the graded sieve holes gradually increase in size from right to left, the positions of different particles passing through the graded sieve holes are also different. At this time, the closer to the left side of the crushing cover, the larger the food waste screened out. This arrangement is conducive to further crushing the food waste by the subsequent mechanism.

[0021] (3) The present invention sets a transmission mechanism. When the crushing shaft rotates, the crushing shaft drives the transmission belt on the transmission disc one to rotate. The rotation of the transmission belt drives the rotating shaft on the transmission disc two to rotate. The rotation of the rotating shaft drives the gear to rotate. The rotation of the gear drives the gear ring to rotate along the limit ring. The rotation of the gear ring drives the spiral rolling plate on the connecting column to rotate. This arrangement is conducive to making the rotation direction of the crushing shaft opposite to the rotation direction of the gear ring. At this time, the rotation direction of the crushing shaft is opposite to the rotation direction of the spiral rolling plate.

[0022] (4) The present invention provides a vibrating screen mechanism, and the kitchen waste crushed by the crushing mechanism passes through, and the vibrating screen plate in the vibrating screen mechanism enters the interior of the fermentation box. When the gear ring rotates, the spiral rolling plate on the connecting column rotates, and the rotation of the spiral rolling plate drives the active extrusion block to rotate. When the active extrusion block is squeezed by the passive extrusion block on the top of the sliding column, the passive extrusion block drives the sliding column to move downward rapidly, and the sliding column moves downward rapidly to drive the vibrating screen plate fixedly connected to the sliding column to move downward along the slide groove in the fixed arc block. When the active extrusion block and the passive extrusion block are squeezed, under the pulling force of the sliding column, the vibration spring drives the vibrating screen plate on the sliding column to rebound quickly, and the continuous rotation of the spiral rolling plate drives the active extrusion block to continuously squeeze the passive extrusion block. Such a setting is conducive to the continuous up and down vibration of the vibrating screen plate, which accelerates the kitchen waste on the vibrating screen plate to pass through the vibrating screen plate, avoids a large amount of kitchen waste from clogging the vibrating screen plate, and improves the working stability of the device.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1, please refer to Figure 1-Figure 4 As shown, the present invention is a food waste fermentation treatment device and a treatment method thereof, comprising a fermentation box 1, a plurality of supporting legs 11 are fixedly connected to the bottom of the fermentation box 1, a discharge port 12 is fixedly connected to the bottom of the fermentation box 1, a closing plate 13 is slidably connected inside the discharge port 12, a connecting plate 14 is fixedly connected to the side wall of the fermentation box 1, a driving motor 15 is fixedly connected to one end of the connecting plate 14 away from the fermentation box 1, a crushing cover 16 is fixedly connected to the top of the fermentation box 1, a crushing cover 17 is fixedly connected to the central axis of the crushing cover 16, and a feed port 18 is fixedly connected to the top of the crushing cover 17, and further comprising:

[0038] The crushing mechanism 2 includes a crushing shaft 201 fixedly connected to the output end of the driving motor 15. The end of the crushing shaft 201 away from the driving motor 15 is fixedly connected to a plurality of crushing blades 202. The crushing blades 202 are arranged in a spiral shape as a whole. The function of this component is that when the food waste fermentation treatment equipment is used, the dehydrated food waste is first poured into the crushing cover 17 through the feed port 18. At this time, the driving motor 15 is started, and the output end of the driving motor 15 rotates to drive the crushing shaft 201 to rotate. The rotation of the crushing shaft 201 drives the crushing blades 202 to rotate. At this time, the rotating crushing blades 202 initially crush the food waste inside the crushing cover 17.

[0039] The grading screening mechanism 3 is arranged inside the crushing cover 17, and the grading screening mechanism 3 includes a conveying blade 301 fixedly connected to the crushing shaft 201. The bottom of the crushing cover 17 is fixedly connected to a first arc-shaped screen plate 302, and a plurality of grading screen holes 303 are opened on the first arc-shaped screen plate 302. The grading screen holes 303 gradually become larger from right to left. The function of this component is that because the plurality of crushing shafts 201 are arranged in a spiral shape, the plurality of crushing blades 202 will convey the preliminarily crushed food waste to the vicinity of the conveying blade 301, and the crushing shaft 201 will drive the food waste to be crushed. The conveying blades 301 rotate, and the conveying blades 301 rotate to convey the preliminarily crushed food waste near the crushing shaft 201 forward along the crushing cover 17. At this time, the food waste inside the crushing cover 17 will be screened through the grading sieve holes 303 on the first arc-shaped sieve plate 302. Because the grading sieve holes 303 gradually become larger from right to left, the positions of different particles passing through the grading sieve holes 303 are also different. At this time, the closer to the left side of the crushing cover 17, the larger the food waste screened out. This arrangement is conducive to the subsequent mechanism to further crush the food waste.

[0040] A transmission mechanism 4 is arranged directly below the crushing shaft 201, and the transmission mechanism 4 includes a transmission disc 1 401 fixedly connected to one end of the crushing shaft 201 close to the driving motor 15, and a transmission belt 402 is transmission-connected to the transmission disc 1 401, and a rotating shaft 403 is rotatably connected to the side wall of the connecting plate 14, and a transmission disc 2 404 is fixedly connected to the rotating shaft 403, and an end of the transmission belt 402 away from the transmission disc 1 401 is transmission-connected to the transmission disc 2 404.

[0041] The transmission mechanism 4 also includes a gear 405 fixedly connected to the end of the rotating shaft 403 away from the connecting plate 14. Both ends of the crushing cover 17 are fixedly connected to the limit ring 406. The limit ring 406 is internally rotatably connected with a gear ring 407, and the gear ring 407 is meshed with the gear 405. The function of this component is to set the transmission mechanism 4. When the crushing shaft 201 rotates, the crushing shaft 201 drives the transmission belt 402 on the transmission disk 1 401 to rotate, and the rotation of the transmission belt 402 drives the rotating shaft 403 on the transmission disk 2 404 to rotate. The rotation of the rotating shaft 403 drives the gear 405 to rotate, and the rotation of the gear 405 drives the gear ring 407 to rotate along the limit ring 406.

[0042] Embodiment 2 is different from Embodiment 1 in that: Figure 1-Figure 9 As shown, a crushing mechanism 5 is arranged inside the crushing cover 16, and the crushing mechanism 5 includes a plurality of connecting columns 501 fixedly connected to the gear ring 407, and a spiral rolling plate 502 is fixedly connected to one end of the connecting column 501 away from the gear ring 407, and a plurality of rolling grooves are opened on one side of the spiral rolling plate 502.

[0043] The crushing mechanism 5 also includes a plurality of fixed blocks 503 fixedly connected to the inner wall of the crushing cover 16, and one end of the fixed block 503 away from the inner wall of the crushing cover 16 is rotatably connected to a rotating shaft 504, and a passive crushing plate 505 is fixedly connected to the rotating shaft 504, and one side of the passive crushing plate 505 is provided with a plurality of crushing grooves, and one side of the passive crushing plate 505 away from the crushing groove is fixedly connected to a plurality of arc springs 506, and one end of the arc spring 506 away from the passive crushing plate 505 is fixedly connected to the inner wall of the crushing cover 16. The function of this component is that the rotation of the spiral crushing plate 502 will drive the larger pieces of food waste inside the crushing cover 16 to rotate, and the food waste will be crushed under the action of centrifugal force. The garbage will move to the rolling groove of the spiral rolling plate 502. When the spiral rolling plate 502 and the passive rolling plate 505 are squeezed, the rolling groove on the spiral rolling plate 502 will cooperate with the rolling groove on the passive rolling plate 505 to further crush the food waste on the spiral rolling plate 502. Since the spiral rolling plate 502 is arranged in a spiral shape, during the rolling process, the spiral rolling plate 502 will transport the rolled food waste to the right end of the spiral rolling plate 502. Since the food waste on the left side is larger in volume, the longer the rolling distance of the larger food waste on the left side is, the longer the rolling time is. This arrangement is beneficial to improving the crushing efficiency of the crushing mechanism 5.

[0044] A vibrating screen mechanism 6 is provided at the bottom of the crushing cover 16. The vibrating screen mechanism 6 includes a plurality of fixed arc blocks 601 fixedly connected to the bottom of the crushing cover 16. A vibrating screen plate 602 is slidably connected inside the fixed arc block 601. A sliding column 603 is slidably connected inside the fixed arc block 601. The sliding column 603 passes through both ends of the vibrating screen plate 602 and is fixedly connected to the vibrating screen plate 602. A vibration spring 604 is sleeved on the sliding column 603. The vibration spring 604 is fixedly connected to the fixed arc block 601. A passive extrusion block 605 is fixedly connected to one end of the sliding column 603 away from the vibration spring 604. Active extrusion blocks 606 are fixedly connected to both ends of the spiral rolling plate 502. The function of this component is to set the vibrating screen mechanism 6, so that the kitchen waste crushed by the crushing mechanism 5 passes through, and the vibrating screen plate 602 in the vibrating screen mechanism 6 enters the interior of the fermentation box 1. When the gear ring 407 rotates, the spiral rolling plate 502 on the connecting column 501 is driven to rotate. The rotation of the spiral rolling plate 502 drives the active extrusion block 606 to rotate. When the active extrusion block 606 is squeezed by the passive extrusion block 605 on the top of the sliding column 603, the passive extrusion block 605 drives the sliding column 603 to move downward quickly. The sliding column 603 moves downward quickly and drives the vibration screen plate 602 fixedly connected to the sliding column 603 to move downward along the slide groove in the fixed arc block 601. When the active extrusion block 606 and the passive extrusion block 605 are squeezed, under the pulling force of the sliding column 603, the vibration spring 604 drives the vibration screen plate 602 on the sliding column 603 to rebound quickly. The continuous rotation of the spiral rolling plate 502 will drive the active extrusion block 606 to continuously squeeze the passive extrusion block 605. This arrangement is conducive to making the vibration screen plate 602 continuously vibrate up and down, accelerating the food waste on the vibration screen plate 602 to pass through the vibration screen plate 602, avoiding a large amount of food waste from clogging the vibration screen plate 602, and improving the stability of the device.

[0045] The processing method of the food waste fermentation processing equipment comprises the following steps:

[0046] S1: Preliminary screening. Several crushing blades 202 will transport the preliminarily crushed food waste to the vicinity of the conveying blades 301. The crushing shaft 201 will drive the conveying blades 301 to rotate. The conveying blades 301 rotate to transport the preliminarily crushed food waste near the crushing shaft 201 forward along the crushing cover 17. At this time, the food waste inside the crushing cover 17 will be screened through the grading sieve holes 303 on the first arc-shaped sieve plate 302;

[0047] S2: By setting the transmission mechanism 4, when the crushing shaft 201 rotates, the crushing shaft 201 drives the transmission belt 402 on the transmission disk 1 401 to rotate, the transmission belt 402 rotates and drives the rotating shaft 403 on the transmission disk 2 404 to rotate, the rotating shaft 403 rotates and drives the gear 405 to rotate, the gear 405 rotates and drives the gear ring 407 to rotate along the limit ring 406, the gear ring 407 rotates and drives the spiral rolling plate 502 on the connecting column 501 to rotate, such a setting is conducive to making the rotation direction of the crushing shaft 201 opposite to the rotation direction of the gear ring 407, and at this time, the rotation direction of the crushing shaft 201 is opposite to the rotation direction of the spiral rolling plate 502;

[0048] S3: Vibration screening, the active extrusion block 606 is squeezed with the passive extrusion block 605 on the top of the sliding column 603, and the passive extrusion block 605 drives the sliding column 603 to move downward quickly. The sliding column 603 moves downward quickly and drives the vibration screen plate 602 fixedly connected to the sliding column 603 to move downward along the slide groove in the fixed arc block 601. When the active extrusion block 606 and the passive extrusion block 605 are squeezed, under the pulling force of the sliding column 603, the vibration spring 604 drives the vibration screen plate 602 on the sliding column 603 to rebound quickly, thereby accelerating the passage of the food waste on the vibration screen plate 602 through the vibration screen plate 602, avoiding a large amount of food waste from clogging the vibration screen plate 602, and improving the working stability of the device.

[0049] A specific application of this embodiment is:

[0050] When the food waste fermentation treatment equipment is used, the dehydrated food waste is first poured into the crushing cover 17 through the feed port 18. At this time, the drive motor 15 is started, and the output end of the drive motor 15 rotates to drive the crushing shaft 201 to rotate, and the crushing shaft 201 rotates to drive the crushing blades 202 to rotate. At this time, the rotating crushing blades 202 initially crush the food waste inside the crushing cover 17. Because the plurality of crushing shafts 201 are arranged in a spiral shape, the plurality of crushing blades 202 will convey the initially crushed food waste to the vicinity of the conveying blades 301. The crushing shaft 201 simultaneously drives the conveying blades 301 to rotate. The conveying blades 301 rotate to convey the initially crushed food waste near the crushing shaft 201 forward along the crushing cover 17. At this time, the food waste inside the crushing cover 17 will be sieved through the grading sieve holes 303 on the first arc-shaped sieve plate 302. Because the grading sieve holes 30 3 gradually increases from right to left, so the positions of different particles passing through the grading sieve holes 303 are also different. At this time, the closer to the left side of the crushing cover 17, the larger the food waste screened out is. This arrangement is conducive to the subsequent mechanism to further crush the food waste. By setting the transmission mechanism 4, when the crushing shaft 201 rotates, the crushing shaft 201 drives the transmission belt 402 on the transmission disk 1 401 to rotate, the transmission belt 402 rotates and drives the rotating shaft 403 on the transmission disk 2 404 to rotate, the rotating shaft 403 rotates and drives the gear 405 to rotate, the gear 405 rotates and drives the gear ring 407 to rotate along the limit ring 406, and the gear ring 407 rotates and drives the spiral rolling plate 502 on the connecting column 501 to rotate. This arrangement is conducive to making the rotation direction of the crushing shaft 201 opposite to the rotation direction of the gear ring 407. At this time, the rotation direction of the crushing shaft 201 is opposite to the rotation direction of the spiral rolling plate 502;

[0051] The rotation of the spiral rolling plate 502 will drive the larger pieces of food waste inside the crushing cover 16 to rotate. Under the action of centrifugal force, the food waste will move to the crushing groove of the spiral rolling plate 502. When the spiral rolling plate 502 and the passive rolling plate 505 are squeezed, the crushing groove on the spiral rolling plate 502 will cooperate with the crushing groove on the passive rolling plate 505 to further crush the food waste on the spiral rolling plate 502. Since the spiral rolling plate 502 is spirally arranged, the spiral rolling will crush the food waste during the crushing process. The plate 502 will convey the crushed food waste to the right end of the spiral crushing plate 502. Since the food waste on the left side is larger in volume, the longer the crushing distance of the food waste with a larger volume on the left side is, the longer the crushing time is. This arrangement is conducive to improving the crushing efficiency of the crushing mechanism 5. By setting the vibrating screen mechanism 6, the food waste crushed by the crushing mechanism 5 passes through the vibrating screen plate 602 in the vibrating screen mechanism 6 and enters the interior of the fermentation box 1. When the gear ring 407 rotates to drive the connection The spiral rolling plate 502 on the column 501 rotates, and the rotation of the spiral rolling plate 502 drives the active extrusion block 606 to rotate. When the active extrusion block 606 is squeezed with the passive extrusion block 605 on the top of the sliding column 603, the passive extrusion block 605 drives the sliding column 603 to move downward quickly. The sliding column 603 moves downward quickly and drives the vibration screen plate 602 fixedly connected to the sliding column 603 to move downward along the slide groove in the fixed arc block 601. When the active extrusion block 606 and the passive extrusion block 605 are squeezed, under the pulling force of the sliding column 603, the vibration spring 604 drives the vibration screen plate 602 on the sliding column 603 to rebound quickly. The continuous rotation of the spiral rolling plate 502 will drive the active extrusion block 606 to continuously squeeze the passive extrusion block 605. This arrangement is conducive to making the vibration screen plate 602 continuously vibrate up and down, accelerating the food waste on the vibration screen plate 602 to pass through the vibration screen plate 602, avoiding a large amount of food waste from clogging the vibration screen plate 602, and improving the stability of the device.
