[0038] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0039] See Figure 1 , Figure 2 and Figure 3 The present invention provides a continuous rotary mixing device, including a frame 1, a cylinder assembly 2 on the frame 1, a stirring assembly 3 in the cylinder assembly 2, and the stirring assembly 3 being driven by a stirring motor 4; wherein the stirring motor 4 can use frequency conversion speed regulation to control the spindle speed, thereby realizing the adjustment of different particle sizes of the raw materials.

[0040] The cylinder assembly 2 includes an upper cylinder 21 and a lower cylinder 22 mounted on the frame 1. A rotating cylinder 23, rotatably connected to the frame 1, is provided between the upper cylinder 21 and the lower cylinder 22. The rotating cylinder 23 is driven by a rotary motor 5. The upper cylinder 21 is provided with a feed inlet 211 and a maintenance port 212, and the lower cylinder 22 is provided with a discharge port 221. The feed inlet 211 is used to feed materials, and the discharge port 221 is used to discharge the mixed materials. The maintenance port 212 facilitates maintenance. Wear-resistant liners can be provided on the inner walls of the upper cylinder 21, the lower cylinder 22, and the rotating cylinder 23 to increase the service life of the equipment.

[0041] The stirring assembly 3 includes a rotating shaft 31 that is driven and connected to the stirring motor 4. The rotating shaft 31 is provided with multiple layers of flexible blades, each layer of flexible blades consisting of multiple flexible blades 34. The flexible blades 34 can be fixedly connected to the rotating shaft 31.

[0042] With the above structure, when mixing clumps or high-moisture-content clay and sandy soil in contaminated soil, the cylinder assembly 2 and the mixing assembly 3 work together. The rotary motor 5 drives the rotating cylinder 23 to rotate relative to the upper cylinder 21 and the lower cylinder 22, which can play an auxiliary role in mixing and improve mixing efficiency. The mixing motor 4 drives the rotating shaft 31 of the mixing assembly 3, which can drive the flexible blades 34 of the flexible cutter to rotate. Through the rotation of the flexible blades 34, the clumps or high-moisture-content clay and sandy soil can be broken and mixed, so that the added agent can be evenly integrated into the contaminated soil, thereby improving the soil remediation effect.

[0043] In one embodiment, see Figure 3 The rotating shaft 31 has fixed flanges 32 at both ends, and multiple movable flanges 33 are arranged between the two fixed flanges 32. Each layer of flexible cutters is clamped by two movable flanges 33. Multiple adjusting rods 35 are arranged on the two fixed flanges 32. One end of the flexible blade 34 is set on the adjusting rod 35, and the adjusting rod 35 passes through the movable flange 33. One end of the flexible blade 34 of the flexible cutter can be equipped with a movable locking buckle for easy connection to the adjusting rod 35, while the other end is made of wear-resistant materials such as hard alloy to reduce wear and replacement cycles. In practical applications, the distance between adjacent layers of flexible cutters can be adjusted by the movable flanges 33 to facilitate adjustments according to mixing requirements.

[0044] The adjusting rod 35 is a lead screw, and adjusting nuts are provided on both sides of the adjusting rod 35 corresponding to the movable flange 33. In practical applications, the position of the movable flange 33 on the adjusting rod 35 can be adjusted by the threaded engagement of the adjusting nuts and the adjusting rod 35, so as to adjust the distance between adjacent flexible cutters.

[0045] In one embodiment, see Figure 3 The flexible blade 34 includes a blade 341 and a chain 342. One end of the chain 342 is connected to the blade 341, and the other end is connected to the adjusting rod 35. In practical applications, the chain 342 and the blade 341 work together to allow the blade 341 to be flexibly connected to the adjusting rod 35, thereby enabling the rotating shaft 31 to swing the blade 341, thus ensuring the crushing effect.

[0046] In one embodiment, see Figure 1 , Figure 2 and Figure 4The rotating cylinder 23 has gaps with both the upper cylinder 21 and the lower cylinder 22. Material-blocking components 24 are installed on the upper cylinder 21 and the lower cylinder 22 at positions corresponding to these gaps. Each material-blocking component 24 includes a rubber baffle 241 installed on the upper cylinder 21 and the lower cylinder 22, covering the gaps. In practical applications, the rubber baffles 241 of the material-blocking component 24 can seal the gaps to prevent material leakage.

[0047] The baffle assembly 24 also includes a pressure plate 242, which presses tightly against the surface of the rubber baffle 241. In practical applications, the pressure plate 242 can tightly fix the rubber baffle 241 to the upper cylinder 21 and the lower cylinder 22.

[0048] In one embodiment, see Figure 2 Multiple scraper blades 25 are provided between the upper cylinder 21 and the lower cylinder 22, and there is a gap between the scraper blades 25 and the inner surface of the rotating cylinder 23. In practical applications, by installing the two ends of the scraper blades 25 on the upper cylinder 21 and the lower cylinder 22, the rotating cylinder 23 moves relative to the scraper blades 25 when it rotates, thereby scraping off the high-humidity material on the combat suit and the inner wall. Setting a certain gap between the scraper blades 25 and the inner surface of the rotating cylinder 23 can avoid interference when the rotating cylinder 23 rotates.

[0049] In one embodiment, see Figure 1 , Figure 2 and Figure 4 The output end of the stirring motor 4 is equipped with an output pulley 41, and the rotating shaft 31 is equipped with a transmission pulley 42. The output pulley 41 and the transmission pulley 42 are connected by a transmission belt 43. In practical applications, the power of the stirring motor 4 can be transmitted to the rotating shaft 31 through the cooperation of the output pulley 41, the transmission pulley 42, and the transmission belt 43, so as to drive the rotation of the rotating shaft 31. Protective covers can be installed at the positions of the output pulley 41, the transmission pulley 42, and the transmission belt 43 to protect these transmission components.

[0050] The output end of the rotary motor 5 is equipped with an output gear 51, and the rotating cylinder 23 is equipped with a transmission gear 52. The output gear 51 and the transmission gear 52 mesh with each other. In practical applications, the power of the rotary motor 5 can be transmitted to the rotating cylinder 23 through the cooperation of the output gear 51 and the transmission gear 52, so as to drive the rotation of the rotating cylinder 23. Protective covers can be installed at the positions of the output gear 51 and the transmission gear 52 to protect the transmission components.

[0051] Multiple radial rollers 53 and axial rollers 54 are arranged on the frame 1 at positions corresponding to the rotating cylinder 23, with both radial rollers 53 and axial rollers 54 abutting against the rotating cylinder 23. In practical applications, the radial rollers 53 and axial rollers 54 provide radial and axial support for the rotating cylinder 23, thereby ensuring its stable rotation.

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.

[0053] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications can be made based on the above-described invention, and these changes or modifications still fall within the scope of the present invention.
