The recovery and treatment device 2 is located at the lower left side of the frame 1. A plate 3 is slidably installed inside the frame 1. A lifting assembly 4, which is poweredly connected to the plate 3, is provided on the top of the frame 1. A shell plate 5 is provided on the upper surface of the plate 3. A first cleaning power assembly 6 is provided in the middle of the shell plate 5. A second cleaning power assembly 7 is provided on one side of the first cleaning power assembly 6. The lifting assembly 4 drives the plate 3, shell plate 5, first cleaning power assembly 6, and second cleaning power assembly 7 to move up and down. The recovery and treatment device 2 includes a recovery tank 21 and a treatment tank 22 located below the inside of the recovery tank 21. The first cleaning power assembly 6 is poweredly connected to a first cleaning mechanism 12 located above the inside of the recovery tank 21 for cleaning the inner wall of the recovery tank 21. The second cleaning power assembly 7 is poweredly connected to a self-cleaning assembly 27 located inside the treatment tank 22 for cleaning the inner wall of the treatment tank 22.

[0024] The recycling and processing equipment 2 is provided with a feed inlet 11 at the front, a main control box 8 is provided on the left side of the recycling and processing equipment 2, a control valve 9 is installed and connected at the bottom outlet of the recycling and processing equipment 2, and a filter pump 10 is connected to the left side of the control valve 9.

[0025] The recycling tank 21 is provided with a double-layer rotating flange assembly 23 at the top and a support leg 24 at the bottom. The upper surface of the double-layer rotating flange assembly 23 is provided with a shaft housing 25. The shaft housing 25 is provided with a drive shaft 26 inside. One end of the drive shaft 26 passes through the double-layer rotating flange assembly 23 and is connected to the self-cleaning assembly 27, and the other end is connected to the first cleaning power assembly 6.

[0026] The lifting assembly 4 includes a driver 41 located at the top of the frame 1. A lead screw 42 is connected to the driver 41 below it. The lead screw 42 is connected to the shell plate 5 through a lead sleeve 43. The bottom of the lead screw 42 is fixedly connected to the plate 3.

[0027] Guide rods 31 are provided on both sides of the plate 3. The upper ends of the guide rods 31 are fixedly connected to the frame 1 by fixing bolts 32. The guide rods 31 are connected to the shell plate 5 by guide rod sleeves 33.

[0028] The second cleaning power assembly 7 includes a second motor 701 disposed on one side of the shell plate 5. A reducer 703 is disposed on the lower surface of the plate 3 on the other side of the second motor 701. The output end of the second motor 701 is connected to the reducer 703 through a belt pulley transmission assembly 702. The output end of the reducer 703 is poweredly connected to the first cleaning mechanism 12.

[0029] The first cleaning mechanism 12 includes a square tube 201, on the side of which a curved cleaning scraper 202 is installed.

An angle adjustment shaft 205 is provided inside the second coupling 204, and the angle adjustment shaft 205 is connected to the reducer 703.

[0030] In this embodiment, when the inner wall of the recycling tank needs to be cleaned (since the material entering through the feed inlet goes directly into the processing tank for processing, the recycling tank does not need to be cleaned frequently), the second motor is started. The second motor drives the reducer through the belt pulley transmission assembly. The reducer drives the square tube and the cleaning scraper to rotate through the angle adjustment shaft and the second coupling, thereby changing the cleaning angle of the cleaning scraper on the inner wall of the recycling tank, which facilitates better cleaning of the inner wall of the recycling tank. After the angle is adjusted, the recycling tank as a whole is rotated relative to the double-layer rotating flange assembly through the corresponding rotating device (in actual use, universal wheels can be installed at the bottom of the support legs to improve the rotation effect), which, together with the cleaning scraper of the first cleaning mechanism, realizes the inner wall cleaning operation.

[0031] This invention relates to a solvent recovery and treatment device for acetonitrile synthesis. In use, the solution inside the treatment tank 22 is treated by the recovery and treatment equipment 2. After treatment, the control valve 9 is opened, and the solution is discharged after filtration by the filter pump 10. The first cleaning power component 6, in conjunction with the self-cleaning component 27, cleans the inner wall of the treatment tank 22 after the solution is discharged, preventing the tank from rusting and causing damage due to the remaining solution. When cleaning the recovery tank 21 is required, the angle of the first cleaning mechanism 12 is adjusted by the second cleaning power component 7, working in conjunction with the rotating recovery and treatment equipment 2 to clean the inner wall of the recovery tank 21. During the cleaning process, the lifting component 4 can be used to drive the plate 3 and the corresponding first and second cleaning power components 6 and 7, allowing for height adjustment according to the area to be cleaned, thereby improving the cleaning effect. This invention has the advantages of reasonable structure, segmented cleaning structure, good cleaning effect, and strong practicality. Example 2

A first cleaning power assembly 6 is provided in the middle of the shell plate 5. A second cleaning power assembly 7 is provided on one side of the first cleaning power assembly 6. The lifting assembly 4 drives the plate 3, shell plate 5, first cleaning power assembly 6, and second cleaning power assembly 7 to move up and down. The recovery and treatment device 2 includes a recovery tank 21 and a treatment tank 22 located below the inside of the recovery tank 21. The first cleaning power assembly 6 is poweredly connected to a first cleaning mechanism 12 located above the inside of the recovery tank 21 for cleaning the inner wall of the recovery tank 21. The second cleaning power assembly 7 is poweredly connected to a self-cleaning assembly 27 located inside the treatment tank 22 for cleaning the inner wall of the treatment tank 22.

[0033] The recycling and processing equipment 2 is provided with a feed inlet 11 at the front, a main control box 8 is provided on the left side of the recycling and processing equipment 2, a control valve 9 is installed and connected at the bottom outlet of the recycling and processing equipment 2, and a filter pump 10 is connected to the left side of the control valve 9.

[0034] The recycling tank 21 is provided with a double-layer rotating flange assembly 23 at the top and a support leg 24 at the bottom. The upper surface of the double-layer rotating flange assembly 23 is provided with a shaft housing 25. The shaft housing 25 is provided with a drive shaft 26 inside. One end of the drive shaft 26 passes through the double-layer rotating flange assembly 23 and is connected to the self-cleaning assembly 27, and the other end is connected to the first cleaning power assembly 6.

[0035] The self-cleaning component 27 includes a cleaning rod 71 connected to the drive shaft 26. A bearing 72 is provided at the bottom of the cleaning rod 71. Multiple horizontal bars 73 arranged vertically are installed on both sides of the cleaning rod 71. A vertical plate 74 is provided on the outside of the horizontal bar 73. The vertical plate 74 is connected to the horizontal bar 73 through a spring compensation rod 75. Several cleaning brushes 76 are tightly arranged on the outside of the vertical plate 74.

[0036] The first cleaning power assembly 6 includes a first motor 61 mounted on the shell plate 5, and the first motor 61 is poweredly connected to the drive shaft 26 via a first coupling 62.

[0037] In this embodiment, the first motor is started, and the first motor drives the drive shaft to rotate through the first coupling. The drive shaft drives the cleaning rod to rotate, and the cleaning rod drives the vertical plate and the cleaning brush to rotate. During the process of the cleaning brush rotating to clean the inner wall of the treatment tank, the cleaning brush is always in contact with the inner wall of the treatment tank by means of the spring compensation rod, which greatly improves the cleaning force and cleaning effect on the inner wall of the treatment tank.

[0038] The lifting assembly 4 includes a driver 41 located at the top of the frame 1. A lead screw 42 is connected to the driver 41 below it. The lead screw 42 is connected to the shell plate 5 through a lead sleeve 43. The bottom of the lead screw 42 is fixedly connected to the plate 3.

[0040] In this embodiment, the driver is activated, which drives the lead screw to rotate. The bottom end of the lead screw is fixedly connected to the plate, and the lead screw cooperates with the shell plate through a lead sleeve. Therefore, when the driver drives the lead screw to rotate, the lead screw will drive the shell plate to move up and down along the frame, thereby driving the first cleaning power component and the second cleaning power component to move up and down. This realizes the height adjustment of the self-cleaning component and the first cleaning mechanism, which is convenient to make adjustments according to the actual inner wall cleaning needs and greatly improves the cleaning effect. During the movement of the shell plate, it moves on the guide rod through the guide rod sleeve, which further improves the stability and reliability of the overall lifting and adjustment process.

[0041] This invention relates to a solvent recovery and treatment device for acetonitrile synthesis. In use, the solution inside the treatment tank 22 is treated by the recovery and treatment equipment 2. After treatment, the control valve 9 is opened, and the solution is discharged after filtration by the filter pump 10. The first cleaning power component 6, in conjunction with the self-cleaning component 27, cleans the inner wall of the treatment tank 22 after the solution is discharged, preventing the tank from rusting and causing damage due to the remaining solution. When cleaning the recovery tank 21 is required, the angle of the first cleaning mechanism 12 is adjusted by the second cleaning power component 7, working in conjunction with the rotating recovery and treatment equipment 2 to clean the inner wall of the recovery tank 21. During the cleaning process, the lifting component 4 can be used to drive the plate 3 and the corresponding first and second cleaning power components 6 and 7, allowing for height adjustment according to the area to be cleaned, thereby improving the cleaning effect. This invention has the advantages of reasonable structure, segmented cleaning structure, good cleaning effect, and strong practicality.
