[0002] With the improvement of people's living standards and the acceleration of urbanization, the amount of kitchen waste generated is increasing rapidly. Kitchen waste mainly originates from family kitchens, restaurants, and canteens, and its composition is complex, rich in moisture and organic matter. Improper handling not only occupies a large amount of land resources but also emits unpleasant odors, breeds bacteria and pests, seriously pollutes the environment, and even spreads diseases during storage and transportation. Therefore, the efficient treatment of kitchen waste to achieve reduction, harmlessness, and resource recovery has become a crucial issue that urgently needs to be addressed in the field of environmental protection.

[0003] While existing kitchen waste crushing and filter press devices possess basic processing functions, they have significant shortcomings. In the screening stage, traditional screening components rely on static screen plates to select particle size. When faced with entangled fibers and sticky residues, screen clogging frequently occurs, leading to a significant reduction in screening efficiency and affecting the continuity of subsequent processing. Therefore, a kitchen waste crushing and filter press device is proposed. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a kitchen waste crushing and filter press device, comprising a frame 1, which serves as the supporting foundation for the entire device, used to support and fix other components. Two crushing rollers 2 are rotatably connected to the upper side of the frame 1. The crushing rollers 2 rotate and cooperate to crush the kitchen waste, breaking large pieces into smaller particles for easier subsequent processing. Gears 4 are fixedly connected to the outer walls of both crushing rollers 2, meshing with each other. Through the meshing transmission of the gears 4, the two crushing rollers 2 can rotate in opposite directions, ensuring the efficiency and stability of the crushing process. A motor 3 is fixedly connected to the outer wall of the frame 1, with its output end fixedly connected inside one of the crushing rollers 2. The motor 3 serves as a power source, providing power for the rotation of the crushing roller 2. A screening component is arranged in the middle of the frame 1, used to screen the crushed kitchen waste, separating those meeting certain particle size requirements. The screening component separates larger particles that do not meet the requirements. A striking component is installed at the bottom of the screening assembly to prevent screen blockage and ensure screening efficiency and effectiveness. A second collection box 17 is fixedly connected to the left outer wall of the frame 1. This box collects unqualified kitchen waste particles after screening. An auger conveyor 18 is fixedly connected to the top of the second collection box 17, transporting the kitchen waste particles for secondary crushing. A first collection box 16 is fixedly connected to the right outer wall of the frame 1. This box receives qualified kitchen waste after screening and performs pressure filtration. A pressure filter assembly is installed inside the first collection box 16 to squeeze and filter the kitchen waste, removing moisture and reducing its volume for easier storage and transportation.

[0034] Reference Figure 4The screening assembly includes multiple guide rods 5, which are fixedly connected to the inner wall of the frame 1. The guide rods 5 provide guidance for the sliding of the screening plate 6, ensuring that the screening plate 6 remains stable during the sliding process. The screening plate 6 is slidably connected between the outer walls of the multiple guide rods 5. The screening plate 6 achieves the screening of kitchen waste by sliding on the guide rods 5, separating kitchen waste of different particle sizes. The outer wall of the guide rods 5 is fitted with a spring 7, which plays a reset role. After the screening plate 6 is moved by an impact or other external force, it can automatically reset the screening plate 6.

[0035] Reference Figure 5 The striking assembly includes a rotating shaft 8, which is rotatably connected inside the frame 1. The rotating shaft 8 serves as the rotation center of the striking assembly, providing rotational support for components such as the eccentric wheel 9. Multiple eccentric wheels 9 are fixedly connected to the outer wall of the rotating shaft 8. The protruding part of the eccentric wheel 9 is in contact with the bottom of the screening plate 6. Through the eccentric rotation of the eccentric wheel 9, a striking force is generated on the screening plate 6 to prevent the screen holes of the screening plate 6 from clogging. A reciprocating assembly is installed on one side of the rotating shaft 8. The reciprocating assembly is used to drive other subsequent components to move through specific reciprocating motion.

[0036] Reference Figure 5 The reciprocating assembly includes a turntable 10, which is fixedly connected to the outer wall of the rotating shaft 8. The turntable 10 rotates together with the rotating shaft 8 and is the main rotating component of the reciprocating assembly. An eccentric shaft 11 is fixedly connected to the edge of the turntable 10 away from the rotating shaft 8. The eccentric shaft 11 makes a circular motion as the turntable 10 rotates. Through its eccentric setting, the reciprocating motion of the rotating frame 12 is realized. A limit block 13 is fixedly connected to the side of the eccentric shaft 11 away from the turntable 10. The limit block 13 is used to limit the sliding range of the rotating frame 12 on the eccentric shaft 11 and prevent the rotating frame 12 from falling off the eccentric shaft 11. The rotating frame 12 is slidably connected to the outer wall of the eccentric shaft 11. The rotating frame 12 makes a reciprocating motion under the drive of the eccentric shaft 11. Through the connection with other components, the reciprocating motion is transmitted to the required part.

[0037] Reference Figure 6 The filter press assembly includes a connecting rod 14, which is slidably connected to the top of the storage box 16. The connecting rod 14 provides guidance for the up-and-down movement of the pressure plate 15, ensuring that the pressure plate 15 can move vertically up and down during the filter press process. One end of the connecting rod 14 is fixedly connected to the pressure plate 15. Under the drive of the connecting rod 14, the pressure plate 15 squeezes the kitchen waste in the storage box 16 to achieve the filter press function. The other end of the connecting rod 14 is fixedly connected to the bottom of the rotating frame 12. Through the connection with the rotating frame 12, the reciprocating motion of the rotating frame 12 is converted into the up-and-down movement of the pressure plate 15, realizing the automatic operation of the filter press assembly.

[0038] Reference Figure 1 and Figure 5A pulley 19 is fixedly connected to the outer wall of the crushing roller 2, and a pulley 19 is fixedly connected to the outer wall of the rotating shaft 8. A belt 20 is sleeved between the two pulleys 19. Through the transmission of the pulleys 19 and the belt 20, the rotational power of the crushing roller 2 is transmitted to the rotating shaft 8, realizing the rational distribution and transmission of power.

[0039] Reference Figure 3 Two guide plates 21 are fixedly connected to the upper part of the inner wall of the frame 1. The guide plates 21 are used to guide the crushed kitchen waste to move towards the screening component. A guide plate 22 is fixedly connected to the bottom of the frame 1. The guide plate 22 is used to transport the screened kitchen waste into the storage box 16.

[0040] Reference Figure 6 The bottom of the storage box 16 is fixedly connected to a drain pipe 23. The drain pipe 23 is used to drain the water squeezed out during the filter pressing process from the storage box 16. A filter screen 24 is fixedly connected inside the drain pipe 23. The filter screen 24 can prevent kitchen waste particles from being discharged with water, ensuring smooth drainage and separation effect, and avoiding clogging of the drain pipe 23.

[0041] Reference Figure 4 One end of the spring 7 is fixedly connected to the bottom of the screening plate 6, and the other end of the spring 7 is fixedly connected to the inner wall of the frame 1. Through the fixed connection of the two ends of the spring 7, the spring 7 can effectively buffer and reset the screening plate 6. After the screening plate 6 is moved by external force, it can be reset in time.

[0042] Working principle: When kitchen waste needs to be crushed, it is fed into the device. The motor 3 starts, and its output drives one of the crushing rollers 2 to rotate. Through the meshing gears 4 on the outer walls of the two crushing rollers 2, they rotate in opposite directions, crushing the kitchen waste into smaller particles. These crushed particles are then guided by the guide plate 21 and conveyed to the screening plate 6. Simultaneously, the crushing rollers 2 transmit power to the rotating shaft 8 via the pulley 19 and belt 20 on their outer walls, causing the shaft 8 to rotate. The eccentric wheel 9 fixed on the shaft 8 rotates accordingly, generating an impact force on the screening plate 6 during rotation, causing the screening plate 6 to vibrate. This increases screening efficiency and prevents clogging of the screening plate 6.

[0043] When the rotating shaft 8 rotates, the turntable 10 on its outer wall rotates synchronously. The eccentric shaft 11 on the edge of the turntable 10 makes a circular motion, driving the rotating frame 12 to reciprocate. The reciprocating motion of the rotating frame 12 is transmitted to the pressure plate 15 through the connecting rod 14. The connecting rod 14 slides on the top of the storage box 16 to ensure that the pressure plate 15 moves vertically up and down. The pressure plate 15 squeezes the kitchen waste that does not meet the particle size requirements collected in the storage box 16, squeezing out the water.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
