[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods. DETAILED DESCRIPTION

[0022] like Figures 1 to 4 As shown, this embodiment provides a kitchen waste pulping device that can be used to efficiently pulp kitchen waste. The pulp obtained can be used as raw material for subsequent fermentation to prepare fertilizers, biogas, etc., which helps to achieve harmless, resource-based, and fully quantitative treatment of kitchen waste, and is beneficial to environmental protection.

[0023] Specifically, the kitchen waste pulping device includes a housing 10, within which is formed a pulping chamber 11. The housing 10 can be made of a metal material, such as a sheet of steel material. The housing 10 is surrounded by the steel material and has the pulping chamber 11 formed therein. The pulping chamber 11 can extend horizontally.

[0024] The housing 10 is provided with a feed port 12 at the top of the first end of the pulping chamber 11 in the longitudinal direction. The feed port 12 is connected to the pulping chamber 11 and is used to input food waste material to be pulped, such as shredded food waste material, into the pulping chamber 11. The feed port 12 can be connected to the outlet of the shredder device in the previous process.

[0025] The housing 10 is provided with a discharge port 13 at the bottom of the beating chamber 11, which extends along the length of the beating chamber 11. The discharge port 13 is used to discharge the slurry. The discharge port 13 can be connected to the inlet of a fermentation tank in the subsequent process.

[0026] The kitchen waste pulping device also includes a movable blade assembly 20, which is rotatably mounted within the pulping chamber 11. The movable blade assembly 20 cuts the material by rotating and drives the material to move, including rotating. The rotating axis 42 of the movable blade assembly 20 is parallel to the length of the pulping chamber 11.

[0027] The kitchen waste beating device also includes a fixed knife assembly 30, which is arranged in the beating chamber 11 and is located on the outside of the movable knife assembly 20. When the movable knife assembly 20 drives the material to move, the material will move between the movable knife assembly 20 and the fixed knife assembly 30, and the material moves relative to the fixed knife assembly 30, and the fixed knife assembly 30 can cut the material. The movable knife assembly 20 and the fixed knife assembly 30 jointly shear and beat the kitchen waste material. The fixed knife assembly 30 is connected to the shell 10, and the fixed knife assembly 30 extends along the length direction of the beating chamber 11 and includes a plurality of saw teeth arranged along the length direction of the beating chamber 11. The saw teeth are arranged toward the movable knife assembly 20, and the pitch of the saw teeth decreases in the direction away from the feed port 12, including gradually decreasing or decreasing in sections. Saw teeth with a small pitch have a stronger shearing force, which is more conducive to processing harder materials.

[0028] When the kitchen waste beating device of this embodiment is in operation, the kitchen waste material enters the beating chamber 11 from the feed inlet 12 and, under the action of the movable blade assembly 20, rotates within the beating chamber 11 and gradually moves away from the feed inlet 12. The slurry formed by the shearing and beating of the movable blade assembly 20 and the fixed blade assembly 30 is discharged along the length direction of the beating chamber 11 through the corresponding discharge port 13. The saw teeth of the fixed blade assembly 30 near the feed inlet 12 have a larger pitch, which is conducive to beating the soft kitchen waste material first. The saw teeth of the fixed blade assembly 30 away from the feed inlet 12 have a larger pitch, which can further break up the harder material that cannot be crushed by the saw teeth near the feed inlet 12 into a pulp. This embodiment reasonably sets the sawtooth pitch of the fixed knife assembly 30 so that both soft and hard materials in the kitchen waste can be fully processed, avoiding the hard materials in the kitchen waste from being unable to be pulped and being discharged as waste, which affects the full-scale processing of the kitchen waste. It also makes the processing load at each position of the fixed knife assembly 30 uniform, avoiding serious wear of the saw teeth of the fixed knife assembly 30 near the feed port 12.

[0029] In some examples, the fixed knife assembly 30 includes a plurality of fixed knife blocks 31 arranged along the length direction of the beating chamber 11, and each fixed knife block 31 includes a plurality of the saw teeth arranged along the length direction of the beating chamber 11. The plurality of fixed knife blocks 31 is equivalent to dividing the fixed knife assembly 30 into a plurality of segments with saw teeth. The pitch of the saw teeth of different fixed knife blocks 31 is different, and the pitch of the saw teeth on the fixed knife block 31 relatively far away from the feed port 12 is smaller than the pitch of the saw teeth on the fixed knife block 31 relatively close to the feed port 12, thereby achieving a decrease in the pitch of the saw teeth in the direction away from the feed port 12. The pitch of the saw teeth of the same fixed knife block 31 is the same. By distinguishing the pitch of the saw teeth of different fixed knife blocks 31, it is beneficial to the sawtooth processing, the fixed knife block 31 can achieve modular standardization, and the replacement of the fixed knife block 31 is convenient.

[0030] In some examples, there are at least three fixed blade blocks 31, meaning the fixed blade assembly 30 is divided into at least three sections. This facilitates processing of food waste materials of varying hardness and improves processing efficiency. For example, there may be three, four, or five fixed blade blocks 31. Excessive numbers of fixed blade blocks 31 result in minimal improvement in processing efficiency and increased costs.

[0031] In some examples, the discharge port 13 includes multiple sub-discharge ports 14 arranged along the length of the beating chamber 11. The sub-discharge ports 14 can be, for example, funnel-shaped to facilitate the collection and discharge of the slurry. The number of fixed blade blocks 31 is the same as the number of sub-discharge ports 14. The fixed blade blocks 31 are arranged in a one-to-one correspondence with the sub-discharge ports 14, that is, fixed blade blocks 31 are arranged corresponding to different sub-discharge ports 14, facilitating the discharge of the slurry sheared and beaten by different fixed blade blocks 31.

[0032] In some examples, each stationary blade block 31 has the same thickness to avoid dead corners where materials are trapped when different stationary blade blocks 31 are adjacent to each other. In some examples, each stationary blade block 31 has the same length, and stationary blade blocks 31 with different tooth pitches can be installed in different sections according to actual needs, such as the type of food waste.

[0033] In some examples, the shell 10 includes a base 15 and a top plate 16, and the base 15 is connected to the top plate 16 to form the shell 10, and a pulping chamber 11 is formed around it. The base 15 is located below the top plate 16. The feed port 12 can be provided on the top plate 16, and the discharge port 13 can be provided at the bottom of the base 15. The base 15 can include a frame, side plates connected to the sides of the frame, and a discharge funnel connected to the bottom of the frame. A guide plate 17 is also provided on the top plate 16, and the guide plate 17 extends along a spiral angle. When the movable blade assembly 20 rotates, the spiral angle causes the material to move away from the feed port 12, that is, in direction A. The setting of the spiral angle further promotes the material to move in a direction away from the feed port 12. Compared with simply relying on the rotation and stirring of the movable blade assembly 20 to move the material to the surrounding space, the guide plate 17 can improve the material transmission efficiency.

[0034] In some examples, the fixed knife assembly 30 is disposed on the base 15 near the top plate 16 . The fixed knife assembly 30 avoids the discharge port and is easy to install.

[0035] In some examples, the fixed blade assembly 30 includes oblique teeth 32. The oblique teeth 32 are inclined in the same direction as the adjacent guide plate 17. This allows the oblique teeth 32 to cut the material in a forward direction as the material moves along the inclined direction of the guide plate 17, thereby improving shearing efficiency and reducing conveying resistance. The oblique teeth 32 being inclined in the same direction as the adjacent guide plate 17 means that, relative to the vertical direction, the oblique teeth 32 and the adjacent guide plate 17 are tilted toward the same side of the vertical direction, and the inclination angles do not necessarily have to be the same.

[0036] In some examples, the housing 10 further includes a waste outlet 18, which is located at the bottom of the second end of the pulping chamber 11 in the longitudinal direction. Waste outlet 18 is used to discharge materials that cannot be pulped and broken. This material may be plastic, metal, glass, etc. that were not effectively removed during the previous sorting process. Existing pulpers are unable to effectively pulp all of the food waste, and some of the harder food waste merges and is discharged from waste outlet 18. However, this embodiment improves pulping efficiency, with almost no food waste being discharged through waste outlet 18. This embodiment can achieve full processing of food waste.

[0037] In some examples, a screen 19 is provided within the base 15 and positioned between the movable blade assembly 20 and the discharge port 13 to prevent large pieces of material from being discharged without being pulverized to the desired fineness, thereby preventing the material from clogging the discharge port 13. The screen 19 may be arc-shaped and positioned circumferentially outside and adjacent to the movable blade assembly 20 to prevent the material from remaining on the screen 19 without moving.

[0038] In some examples, a plurality of water inlets may be provided on the top plate 16 to facilitate adding water for beating or flushing the beating chamber 11 .

[0039] In some examples, the movable blade assembly 20 includes a plurality of blade discs 21 arranged along the length of the beating chamber 11 and a plurality of movable blade blocks 22 disposed circumferentially of the blade discs 21. The movable blade blocks 22 are provided with serrations at their ends to achieve uniform stirring and shearing along the length of the beating chamber 11. The serrations of the movable blade blocks 22 have a smaller pitch than that of the fixed blade assembly 30, and the movable blade blocks 22 can provide a greater shear force, thereby breaking the material.

[0040] In some examples, the movable blade block 22 is hinged to the cutter disc 21, and the movable blade block 22 can rotate at a certain angle relative to the edge of the cutter disc 21 to prevent large, hard materials from becoming stuck between the movable blade block 22 and the fixed blade block 31. For example, one end of the movable blade block 22 can be hinged to the cutter disc 21, and the other end can be connected to the cutter disc 21 via a return spring, thereby achieving rotation and return of the movable blade block 22.

[0041] In some examples, the food waste pulping device further includes a drive assembly 40, which includes a motor 41 and a rotating shaft 42 in transmission connection with the motor 41. The motor 41 and the rotating shaft 42 can be connected, for example, via a reduction gearbox, a sprocket, a pulley, etc. The motor 41 can be located outside the housing 10. The rotating shaft 42 passes through the housing 10 and extends along the length of the pulping chamber 11. The blade disc 21 is connected to the rotating shaft 42 and is driven to rotate by the rotating shaft 42.

[0042] In some examples, the kitchen waste pulping device further includes a bracket, on which the housing 10 and the driving assembly 40 are both disposed. The bracket is used to provide support and elevate the discharge port 13 .

[0043] Finally, it should be emphasized that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
