[0002] In the waste-to-energy industry, converting waste into electricity requires pretreatment, and waste shredding equipment is a key component of this process. Waste has a complex composition, containing many large pieces of debris. Direct incineration leads to incomplete combustion, resulting in low energy efficiency and the production of harmful gases. Shredding equipment breaks large pieces of waste into uniform particles, increasing the surface area in contact with air, improving incineration efficiency, reducing pollutant emissions, and facilitating subsequent transportation and combustion control. It is a crucial guarantee for achieving waste reduction, harmless treatment, and resource recovery.

[0003] However, existing waste shredding equipment for incineration power generation has significant shortcomings. Traditional equipment can only crush waste and cannot handle the large amount of moisture it contains. This moisture reduces the calorific value of the waste, leading to the need for more auxiliary fuel during incineration and increasing power generation costs. Utility Model Content

[0004] To address the technical problem that existing waste shredding devices for incineration power generation can only crush waste and cannot handle the large amount of moisture contained in the waste, which reduces the calorific value of the waste, leading to the need for more auxiliary fuel during incineration and increasing power generation costs, this utility model provides a waste shredding device for incineration power generation.

[0005] The technical solution adopted by this utility model is: a waste pulverizing device for incineration power generation, including a frame, a pulverizing cylinder fixedly connected to the frame, a first conveying cylinder fixedly connected to the lower side of the frame, a second conveying cylinder fixedly connected to one end of the first conveying cylinder, the second conveying cylinder having a conical structure, a pulverizing component provided in the pulverizing cylinder, a conveying component provided in the first and second conveying cylinders, a squeezing and filtering component provided in the second conveying cylinder, and a driving component for driving the pulverizing component and the conveying component to work on the outside of the frame.

[0006] A further feature of this invention is that the crushing assembly includes a rotating shaft rotatably connected inside the crushing cylinder and multiple sets of crushing blades fixedly connected outside the rotating shaft, and a feed hopper is fixedly connected to the top of the crushing cylinder.

[0007] A further feature of this invention is that the conveying assembly includes a rotating rod and a spiral blade fixedly connected to the outside of the rotating rod. The rotating rod is rotatably connected in a first conveying cylinder and a second conveying cylinder, and the region of the spiral blade in the second conveying cylinder has a conical structure.

[0008] A further feature of this invention is that the driving component is a motor fixedly connected to the frame, and the rotating rod, the rotating shaft, and the output end of the motor are all fixedly connected to pulleys, with a belt sleeved on the outside of the pulleys.

[0009] A further feature of this invention is that the top of the first conveying cylinder is provided with a feed inlet, and the bottom of the crushing cylinder is provided with a discharge outlet.

[0010] A further feature of this invention is that the squeeze filtration assembly is a conical filter cylinder, which is fixedly connected inside the second conveying cylinder.

[0011] A further feature of this invention is that one end of the conical filter cylinder and the second conveying pipe are both provided with a discharge hole, and a discharge pipe is fixedly connected to the bottom of the second conveying cylinder, with one end of the discharge pipe extending into the second conveying cylinder.

[0012] The beneficial effects of this utility model are as follows: In this utility model, the first and second conveying cylinders are connected to each other, forming a conveying channel after the waste is crushed.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described below.

[0023] To address the problems existing in the background technology, this application proposes the following technical solution: a waste pulverizing device for incineration power generation, comprising a frame 1, a pulverizing cylinder 2 fixedly connected to the frame 1, a first conveying cylinder 3 fixedly connected to the lower side of the frame 1, and a second conveying cylinder 4 fixedly connected to one end of the first conveying cylinder 3. The second conveying cylinder 4 has a conical structure. The pulverizing cylinder 2 is equipped with a pulverizing component, and the first and second conveying cylinders 3 and 4 are equipped with conveying components. The second conveying cylinder 4 is also equipped with a squeezing and filtering component. A drive component for driving the pulverizing and conveying components is provided on the outside of the frame 1. The frame 1, as the basic support structure of the entire device, is welded from high-strength steel to ensure that it can withstand the weight of each component and the vibration generated during operation, thus ensuring the stability of the device. The pulverizing cylinder 2, fixed to the frame 1, provides a closed space for the waste pulverizing process, preventing waste fragments from splashing during pulverization and reducing environmental pollution and safety hazards. The first conveying cylinder 3 and the second conveying cylinder 4 on the lower side of the frame 1 are connected to each other to form a conveying channel after the garbage is crushed. The first conveying cylinder 3 is responsible for smoothly conveying the crushed garbage to the second conveying cylinder 4, while the conical structure design of the second conveying cylinder 4 creates favorable conditions for the subsequent squeezing and filtration stage. As the conveying space gradually shrinks, it can squeeze the garbage.

[0024] The shredding assembly is specifically designed to crush waste, breaking down large pieces into smaller particles that facilitate subsequent conveying, water extraction, and complete combustion during incineration power generation. The conveying assembly handles the transfer of waste between stages, ensuring it flows orderly from the shredding cylinder 2 into the first conveying cylinder 3, and then into the second conveying cylinder 4. The water extraction assembly separates moisture from the waste, reducing its water content, increasing its calorific value during incineration, and improving power generation efficiency. The drive assembly provides power to the entire system, driving the shredding and conveying assemblies to work together, ensuring continuity and efficiency at each stage. This integrated design combines waste shredding, conveying, and water extraction functions, reducing connections between devices, improving overall waste treatment efficiency, and saving installation space, making it suitable for use in waste-to-energy plants and similar facilities.

[0025] In this embodiment, the crushing assembly includes a rotating shaft 8 rotatably connected inside the crushing cylinder 2 and multiple sets of crushing blades 9 fixedly connected to the outside of the rotating shaft 8. A feed hopper is fixedly connected to the top of the crushing cylinder 2. The feed hopper at the top of the crushing cylinder 2 adopts a funnel-shaped design, which facilitates the pouring of waste into the crushing cylinder 2. The feed hopper has a large opening to accommodate waste of different sizes, and its inclined inner wall guides the waste smoothly into the crushing area, preventing waste from accumulating and clogging at the feed inlet 11. During the crushing process, the closed structure of the crushing cylinder 2 can effectively block the diffusion of waste debris and odors, improving the working environment. The crushed waste particles are of uniform size, which not only facilitates subsequent conveying and water extraction but also allows for full contact with air during incineration, improving combustion efficiency and reducing the emission of harmful gases. This crushing assembly design has high crushing efficiency, a wide range of applications, and can meet the requirements of waste pretreatment for incineration power generation, laying the foundation for the smooth progress of subsequent processes.

[0026] In this embodiment, the conveying assembly includes a rotating rod 12 and a spiral blade 13 fixedly connected to the outside of the rotating rod 12. The rotating rod 12 is rotatably connected in the first conveying cylinder 3 and the second conveying cylinder 4. The region of the spiral blade 13 in the second conveying cylinder 4 has a conical structure. The conveying assembly is responsible for conveying the crushed waste from the crushing cylinder 2 to the subsequent extrusion and filtration stage. The rotating rod 12, rotatably connected in the first conveying cylinder 3 and the second conveying cylinder 4, can rotate stably under the drive of the drive assembly. The spiral blade 13 on the outside of the rotating rod 12 fits tightly with the inner wall of the conveying cylinder. When the rotating rod 12 rotates, the spiral blade 13 can push the waste along the axial direction of the conveying cylinder to achieve continuous conveying. The blades of the spiral blade 13 are designed with a certain tilt angle, which can generate forward thrust to ensure that the waste does not flow back during the conveying process and improve the conveying efficiency.

[0027] In the first conveying cylinder 3, the spiral blade 13 has a cylindrical structure, which can evenly and smoothly convey the crushed waste to the second conveying cylinder 4. The spiral blade 13 in the second conveying cylinder 4 is designed with a conical structure, matching the conical structure of the second conveying cylinder 4. As the conveying space gradually decreases, the squeezing effect of the spiral blade 13 on the waste gradually increases, which can initially squeeze out some of the water from the waste, while also making the waste more compactly aggregated, preparing it for further dehydration by the subsequent squeezing and filtering components. This conical spiral blade 13 design not only realizes the waste conveying function but also assists in dehydration during the conveying process, improving the overall working efficiency of the device and reducing the workload of subsequent processing stages. Furthermore, the continuous conveying method of the spiral blade 13 avoids the problem of waste clogging during the conveying process, ensuring the continuity and stability of waste treatment.

[0028] In this embodiment, the drive component is a motor 5 fixedly connected to the frame 1. Pulleys 6 are fixedly connected to the rotating rod 12, the rotating shaft 8, and the output end of the motor 5. A belt 10 is fitted around the outside of the pulleys 6. The drive component is the power source for the entire device. The motor 5, fixed to the frame 1, is selected with a suitable power output to provide stable power output. The output end of the motor 5 transmits power to the rotating rod 12 and the rotating shaft 8 through the cooperation of the pulleys 6 and the belt 10, realizing the coordinated operation of the crushing and conveying components. The transmission method of pulleys 6 and belt 10 has advantages such as simple structure, smooth transmission, and convenient maintenance. It can buffer vibration and impact within a certain range, protecting the motor 5 and other components.

[0029] The dimensions of the rotating rod 12, rotating shaft 8, and pulley 6 at the output end of the motor 5 are rationally designed to achieve suitable rotational speeds via belt 10, ensuring that the crushing blade 9 and spiral blade 13 operate at optimal speeds. The crushing blade 9 requires high rotational speeds for efficient crushing, while the rotational speed of the spiral blade 13 must match the conveying speed of the waste to prevent waste accumulation or excessive conveying speed. The cooperation between pulley 6 and belt 10 allows the motor 5 to drive multiple components simultaneously, reducing the number of power sources, lowering manufacturing costs and energy consumption, and simplifying the equipment structure for easier installation and maintenance. When adjusting the operating speed, simply replace the pulley 6 with one of different sizes; operation is flexible and convenient. This drive component design ensures coordinated operation of all components, improving the equipment's efficiency and reliability.

[0030] In this embodiment, the top of the first conveying cylinder 3 is provided with a feed inlet 11, and the bottom of the crushing cylinder 2 is provided with a discharge outlet. The extrusion filtration assembly is a conical filter cylinder 14, which is fixedly connected inside the second conveying cylinder 4. Both the conical filter cylinder 14 and the second conveying cylinder have discharge holes 15 at one end. The bottom of the second conveying cylinder 4 is fixedly connected to a discharge pipe 7, one end of which extends into the second conveying cylinder 4. The conical filter cylinder 14 of the extrusion filtration assembly cooperates with the conical structure of the second conveying cylinder 4 to form a gradually narrowing space. When waste is conveyed into the second conveying cylinder 4, it enters the gap between the conical filter cylinder 14 and the second conveying cylinder 4 under the push of the spiral blade 13. As the space gradually narrows, the extrusion pressure on the waste continuously increases, and the water is squeezed out. The conical filter cylinder 14 has many small filter holes on its wall, allowing the squeezed-out water to permeate through these holes into the second conveying cylinder 4 and then be discharged through the discharge pipe 7 at the bottom, thus achieving waste dehydration. The dehydrated waste is discharged through the discharge hole 15 at one end of the conical filter cylinder 14 and the second conveying cylinder 4, and then enters the subsequent incineration stage.

[0031] The conical filter cartridge 14 not only filters water but also guides the waste, ensuring its smooth discharge. The discharge pipe 7 collects and discharges the filtered wastewater for centralized treatment, preventing environmental pollution. This squeeze-type filtration assembly design effectively reduces the moisture content of the waste, increases its calorific value, which is beneficial for subsequent incineration power generation, while also reducing wastewater discharge and meeting environmental protection requirements.

[0032] The method of using this utility model is as follows:

[0033] When the motor 5 is started, it drives the rotating shaft 8 and the rotating rod 12 to rotate through the pulley 6 and the belt 10. The garbage is then poured into the crushing cylinder 2. The rotating shaft 8 drives the crushing blade 9 to work, thereby crushing the garbage. The crushed garbage falls into the first conveying cylinder 3. The rotating rod 12 drives the spiral blade 13 to rotate. The crushed garbage is conveyed to the second conveying cylinder 4 through the rotating rod 12 and the spiral blade 13. Due to the conical shape of the second conveying cylinder 4 and the conical filter cylinder 14, the garbage in the second conveying cylinder 4 can be squeezed and filtered. The filtered wastewater is discharged through the discharge pipe 7, and the squeezed and filtered garbage is discharged through the discharge hole 15.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
