[0007] Furthermore, the rotating cylinder is a shape memory alloy mandrel. When the rotating cylinder drives the bionic blade to rotate, it expands after being heated to the rated temperature, and the radius of curvature of the bionic blade decreases.

[0008] Furthermore, the crushing assembly includes a crushing frame, a crushing rack, a crushing lifting block, a crushing motor, a crushing shaft, and crushing blades. The crushing rack is fixed to the inner wall of the primary processing assembly. The crushing lifting block is installed on both sides of the crushing frame.

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] The implementation of this application will be described in detail below with reference to specific embodiments.

[0020] like Figure 1-6 As shown, this application provides an integrated sludge dewatering and solidification reduction machine based on biomimetic blades and differential drums, including a primary treatment component 1, a dewatering component 2, and an extrusion component 4. The primary treatment component 1 is connected to the dewatering component 2. The extrusion component 4 is located at the bottom of the dewatering component 2. The primary treatment component 1 is equipped with a crushing component and a conveying component. The crushing component is slidably connected to the interior of the primary treatment component 1. The conveying component is fixed inside the primary treatment component 1 and is connected to the crushing component and the conveying component. The conveying component is connected to the extrusion component 4. The conveying component is equipped with a rotatable spiral shaft 39. A spiral plate 40 is detachably connected to the spiral shaft 39. The spiral plate 40 is made of shape memory alloy. The extrusion component 4 is equipped with multiple differential drums 18 in the middle. The dewatering component 2 is equipped with a rotatable drum 9.

The extrusion component 4 is installed in the middle of a support component 3. The support component 3 is used to fix the extrusion component 4. A leveling device is provided at the bottom of the support component 3 to ensure the stability of the equipment.

[0021] In this embodiment, the primary processing component 1 includes a crushing component and a conveying component. The crushing component is slidably connected to the primary processing component 1, and the conveying component is fixedly connected therein. The crushing component, conveying component, and extrusion component 4 are sequentially connected. The crushing component can crush the sludge, breaking down large pieces of sludge into smaller particles, which facilitates subsequent dewatering and other treatments. The conveying component is responsible for transporting the crushed sludge to the extrusion component 4. This structural design integrates the initial crushing and conveying of sludge, improving processing efficiency and laying the foundation for subsequent deep processing. The spiral shaft 39 inside the conveying component is detachably connected to a spiral plate 40 made of shape memory alloy. The rotating drum 9 is a shape memory alloy mandrel. During the rotation of the bionic blade 10 driven by the rotating drum 9, it expands after reaching the rated temperature, and the radius of curvature of the bionic blade 10 decreases.

[0022] In this embodiment, the shape memory alloy spiral plate 40 can change shape with environmental changes, better adapt to the state of sludge during the conveying process, and improve the conveying effect; the detachable design facilitates later maintenance and replacement, reducing equipment maintenance costs.

[0023] The crushing assembly includes a crushing frame 19, a crushing rack 20, a crushing lifting block 21, a crushing motor 22, a crushing shaft 23, and crushing blades 24.

Multiple evenly spaced crushing blades 24 are provided on the outer wall of the crushing shaft 23.

[0024] In this embodiment, the crushing rack 20 of the crushing component is fixed to the inner wall of the primary processing component 1. The gear of the crushing lifting block 21 meshes with the rack, allowing the crushing frame 19 to rise and fall. Simultaneously, the crushing shaft 23 drives the crushing blades 24 to rotate and crush the sludge. The rising and falling of the crushing frame 19 can adjust the crushing position. Combined with the rotation of the crushing blades 24, sludge in different positions and states can be fully crushed, improving crushing efficiency and degree of crushing, making the sludge more uniform, and facilitating subsequent processing.

[0025] The crushing frame 19 is equipped with a cleaning bracket 25, a cleaning support rod 26, a cleaning head 27, and a cleaning pipe 28.

The drum 9 is a shape memory alloy spindle, which expands after being heated to a rated temperature, reducing the radius of curvature of the bionic blades 10. The drum 9 drives the bionic blades 10 to rotate, thus achieving sludge dewatering. The shape memory alloy properties allow the curvature of the bionic blades 10 to change when heated, enhancing the stirring and squeezing effect on the sludge and improving dewatering efficiency. The bionic blades 10 are detachable, facilitating cleaning and replacement and ensuring the stability of the dewatering effect. The dewatering assembly 2 also includes a dewatering motor 5, a dewatering transmission belt 6, a dewatering cover plate 7, and a dewatering shaft 8. The dewatering motor 5 drives the dewatering shaft 8 to rotate via the transmission belt, providing power to the drum 9 and ensuring stable operation of the dewatering process.
