A U-shaped plate 16 is fixedly connected to the top of the fixed base 1, and the bottom of each of the two fixed blocks 15 is fixedly connected to the top of the U-shaped plate 16. Two sliding holes adapted to the No. 1 blocks 17 are opened on the top of the U-shaped plate 16, and the outer sides of each of the two No. 1 blocks 17 are slidably connected to the inner side of the corresponding sliding holes.

The outer side of the No. 1 screw 18 is threadedly connected to the inner side of each of the two No. 1 blocks 17. A recovery mechanism is provided on the top of the fixed base 1.

[0028] Among them, the movable frame 21 can move synchronously, and then the third connecting rod 20 starts to rotate, which causes the circular plate 19 to drive the first screw 18 to rotate. Then the first block 17 can move horizontally, which causes the first connecting rod 13 to rotate. At this time, the second connecting rod 14 can also rotate, and then the movable table 2 can move vertically.

[0029] The recovery mechanism includes: a turbine body 4, with a buffer box 3 fixedly connected to the top of the moving platform 2, a connecting pipe 5 fixedly connected to one side of the buffer box 3, the other end of the connecting pipe 5 fixedly connected to the outside of the turbine body 4, a liquid outlet pipe 6 fixedly connected to the inside of the turbine body 4, a housing 10 fixedly connected to the outside of the turbine body 4, a connecting shaft 12 rotatably connected to the inside of the housing 10, turbine blades 11 fixedly connected to the bottom of the connecting shaft 12, a storage tank 7 fixedly connected to the other end of the liquid outlet pipe 6, and the right side of the storage tank 7 fixedly connected to the left side of the moving platform 2. Circular plates 19 are fixedly connected to both sides of the first screw 18, and one side of each circular plate 19 is rotatable. The system is connected by a third connecting rod 20, and the other ends of both third connecting rods 20 are rotatably connected to the same movable frame 21. The top of the fixed base 1 is provided with a sliding groove that matches the movable frame 21. The outer side of the movable frame 21 is slidably connected to the inner side of the sliding groove. A servo motor 23 is fixedly connected to the inner wall of one side of the sliding groove. A rotating rod 24 is fixedly connected to the output end of the servo motor 23.

[0030] The inner side of the fixed base 1 is rotatably connected to the outer side of the rotating rod 24, and two triangular plates are fixedly connected to one side of the fixed base 1. The inner sides of the two triangular plates are rotatably connected to the outer side of the same second screw 22.

The inner sides of the first frame and the second frame are respectively fixedly sleeved on the outer side of the liquid outlet pipe 6 and the connecting pipe 5, which allows the device to operate stably.

[0031] A control valve 8 and a pressure gauge 9 are installed on the outside of the connecting pipe 5, and an inlet pipe is fixedly connected to one side of the buffer tank 3. A controller 27 is fixedly connected to the top of the moving platform 2, and the controller 27 is electrically connected to the pressure gauge 9 and the control valve 8.

Two vertical blocks are integrally formed on the top of the fixed base 1, and the outer sides of the two vertical blocks are slidably connected to the inside of the moving platform 2, which allows the moving platform 2 to be raised and lowered stably.

[0032] The working principle of the above embodiments is as follows:

[0033] In operation, the device is placed in a suitable location, and the user connects the factory's high-pressure methanol waste liquid pipeline to the device's inlet pipe. The high-pressure liquid then enters the buffer tank 3 for temporary storage. As the pressure inside the tank gradually stabilizes, the user controls the controller 27 to open the control valve 8. The high-pressure liquid inside the buffer tank 3 then begins to flow from the connecting pipe 5 into the turbine body 4, causing the turbine blades 11 to rotate. The turbine blades 11 then drive the connecting shaft 12 to move synchronously. The user can install the connecting shaft 12 with a corresponding generator according to their needs. The device then begins energy conversion, enabling it to generate electricity for the user. Simultaneously, the liquid pressure decreases, and the liquid flows from the outlet pipe 6 into the storage tank 7. The storage tank 7 allows the user to recover and store the low-pressure liquid for subsequent process operations. Pressure gauge 9 can monitor the pressure in the pipeline in real time. When an abnormality occurs, it immediately sends a signal to controller 27. At this time, controller 27 can close control valve 8 to ensure user safety. When the user needs to adjust the height of the device, servo motor 23 is started, which causes rotating rod 24 to start rotating. Then, worm gear 25 starts rotating, followed by worm wheel 26, which causes screw 22 to move synchronously. Then, moving frame 21 moves synchronously, followed by connecting rod 20 to start rotating. This causes circular plate 19 to drive screw 18 to rotate, and block 17 to move horizontally, which causes connecting rod 13 to rotate. At the same time, connecting rod 14 can also rotate, and moving platform 2 can move vertically. At this time, the device can be adjusted to the required height according to the user's needs.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
