[0011] As a preferred embodiment of this utility model, the movable component includes support feet arranged around the bottom of the base, a pair of telescopic cylinders 4 symmetrically arranged at the bottom of the base, a lifting plate arranged at the bottom of the telescopic rods of the two telescopic cylinders 4, a pair of guide rails 2 symmetrically arranged on the inner walls of both sides of the bottom of the base, the lifting plate being slidably arranged on the guide rails 2, universal casters being arranged around the bottom of the lifting plate, and a pair of handrails symmetrically arranged on both sides of the mounting frame 2.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] This invention features an easy-to-clean component. A motor drives a lead screw to rotate, achieving linear motion of a drive block, which in turn moves the distillation column cover and cap. The cap not only effectively seals the distillation column body, preventing wastewater splashing during cleaning, but also integrates a water sprayer and an inner wall cleaning brush. The water sprayer rinses the inner wall of the distillation column, while the inner wall cleaning brush wipes away residual material, ensuring the column's cleanliness. Furthermore, the extension and retraction of a telescopic cylinder allows the cap to close or open, and a telescopic cylinder allows the inner wall cleaning brush to move vertically. Simultaneously, a motor drives a rotating shaft to rotate, transmitting power through gears one and two, and then the rotating shaft to rotate the turntable, which in turn rotates the inner wall cleaning brush, achieving a comprehensive and thorough cleaning. This not only improves cleaning efficiency but also greatly simplifies the cleaning process and reduces the workload of staff.

[0014] This invention, through the installation of a movable component and the extension or retraction of the telescopic cylinder four, enables the lifting plate to move up and down along the guide rail, thereby controlling the contact state between the swivel casters and the ground. When the distillation column needs to be moved, the lifting plate descends, the swivel casters contact the ground, and the staff can easily push the entire device using the handrails. This makes it very convenient for the distillation column to be maintained or moved to other work sites. When the distillation column is in operation, the lifting plate rises, the support feet contact the ground, ensuring the stability of the entire device. This not only improves work efficiency but also enhances the ease of use of the device. Attached Figure Description

The guide rails 67 provide sliding tracks for the drive blocks 65 and the drive blocks 66.

[0025] A pair of telescopic cylinders 68 are symmetrically arranged at the bottom of the drive block 65. The telescopic cylinders 68 raise the distillation column cover 69 by retracting the telescopic rod, which facilitates the subsequent cleaning of the distillation column body 4. The bottom of the two telescopic cylinders 68 is provided with a distillation column cover 69 corresponding to the distillation column body 4. The distillation column cover 69 is used to seal the top of the distillation column body 4 during distillation operations to prevent material volatilization or contamination.

A pair of telescopic cylinders 619 are symmetrically arranged at the bottom of the rotary table 617. The telescopic cylinders 619 control the raising and lowering of the cover 620 by the extension and retraction of the telescopic rod to seal or open the distillation column body 4. The bottom of the two telescopic cylinders 619 is provided with cover 620, which is used to close the distillation column body 4 to prevent sewage from splashing during cleaning.

[0027] The bottom of the cap 620 is provided with a guide column and guide sleeve 621, which provides a sliding track for the lifting guide column 623. A telescopic cylinder 622 is provided inside the guide column and guide sleeve 621. The telescopic cylinder 622 drives the lifting guide column 623 to rise and fall through the extension and retraction of the telescopic rod, so that the inner wall cleaning brush 625 moves in the vertical direction. The bottom of the telescopic rod of the telescopic cylinder 622 is provided with the lifting guide column 623. The lifting guide column 623 is slidably set in the guide column and guide sleeve 621. The lifting guide column 623 provides an installation base for the inner wall cleaning brush 625. The inner wall cleaning brush 625 is sleeved on the outside of the lifting guide column 623. The inner wall cleaning brush 625 wipes the inner wall of the distillation column body 4 to remove residual material.

[0028] A water pump 626 is installed on one side of the cap 620. The water pump 626 provides water to the sprayer 628. A water pumping pipe 627 is installed on one side of the water pump 626. The water pumping pipe 627 connects the water pump 626 and the external water source. Sprayers 628 are installed around the bottom of the cap 620. Several sprayers 628 are connected to the water pump 626. The sprayers 628 rinse the distillation column body 4.

[0029] The movable component 2 includes support feet 21 arranged around the bottom of the base 1. The support feet 21 are located at the bottom of the base 1. When the telescopic cylinder 22 retracts, the support feet 21 contact the ground, providing stable support. A pair of telescopic cylinders 22 are symmetrically arranged at the bottom of the base 1. The telescopic cylinders 22 move the lifting plate 23 up and down along the guide rail 24 by extending or retracting the telescopic rod, thereby realizing the movement or fixation of the device. The lifting plate 23 is arranged at the bottom of the telescopic rod of the two telescopic cylinders 22. The lifting plate 23 provides the mounting base for the universal casters 25. A pair of guide rails 24 are symmetrically arranged on the inner walls of both sides of the bottom of the base 1. The lifting plate 23 is slidably arranged on the guide rails 24. The guide rails 24 provide the sliding track for the lifting plate 23 to ensure the smooth movement of the lifting plate 23. Universal casters 25 are arranged around the bottom of the lifting plate 23. When the lifting plate 23 descends, the universal casters 25 contact the ground, facilitating the movement of the device. A pair of handrails 26 are symmetrically arranged on both sides of the mounting frame 25. The handrails 26 facilitate the workers to push the whole device.

[0030] During operation, after each distillation cycle, a small amount of material remains in the column body 4. This requires activating the easy-cleaning component 6 to clean the column body 4, ensuring the purity of the material obtained in the next distillation. First, the telescopic cylinder 68 is activated, causing the column cover 69 to rise by retracting its telescopic rod. Then, the motor 64 is activated, driving the lead screw 63 to rotate. This rotational motion of the lead screw 63 is converted into linear motion of the drive blocks 65 and 66, thus driving the column. Moving block 1 65 and driving block 2 66 move along guide rail 1 67. Driving block 1 65 drives telescopic cylinder 1 68 and distillation column cover 69 to move. At the same time, driving block 2 66 drives the sealing cover 620 to move directly above the distillation column body 4. The operator connects the discharge device at the bottom of the distillation column body 4 to the sewage pipe. Then, telescopic cylinder 2 619 is activated. The telescopic rod of telescopic cylinder 2 619 extends, causing the sealing cover 620 to descend and cover the distillation column body 4, preventing sewage from splashing during the cleaning operation and increasing efficiency. To reduce the workload of the staff, the staff connected the water pipe 627 on one side of the water pump 626 to an external water source to supply water to the water sprayer 628 at the bottom of the cover 620. Then, the second motor 611 was started. The second motor 611 drove the first shaft 612 and the first gear 613 to rotate. The first gear 613 drove the second gear 618 and the second shaft 615 to rotate. The second shaft 615 transmitted power to the rotating table 617, which drove the cover 620, the water sprayer 628, and the inner wall cleaning brush 625 to rotate. The water sprayer 628 rinses the distillation column body 4, and the inner wall cleaning brush 625 wipes the inner wall of the distillation column body 4 to remove residual material and ensure the cleanliness of the distillation column body 4. At the same time, the telescopic cylinder 622 is activated. The telescopic rod of the telescopic cylinder 622 extends and retracts, driving the lifting guide column 623 to rise and fall along the guide sleeve 621, thereby moving the inner wall cleaning brush 625 in the vertical direction to clean the inner wall of the distillation column body 4 and ensure thorough cleaning. Wastewater is discharged from the discharge device at the bottom of the distillation column body 4 through the sewage pipe.

[0031] When the distillation column requires regular maintenance, the operator can activate telescopic cylinder 22. The telescopic rod of telescopic cylinder 22 extends, causing the lifting plate 23 to descend along guide rail 24. The casters 25 then contact the ground, and the operator can push the entire unit using the handrail 26 to move it to the maintenance point. When maintenance or distillation operations are required, the telescopic rod of telescopic cylinder 22 can be retracted, causing the lifting plate 23 to rise along guide rail 24. The support feet 21 then contact the ground, ensuring the stability of the entire unit.

[0032] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof.
