[0024] The present application provides a distillation still cleaning assembly and cleaning process for menthol preparation.

[0025] Advantages:

[0026] 1、By setting the outer support assembly, when the driving motor two is started, its output end drives the screw rod two to rotate, because there is a threaded connection between the screw rod two and the moving cylinder, and the guide rod supports and guides the moving cylinder, so that the moving cylinder can move back and forth along the axial direction of the screw rod two, and the movement of the moving cylinder is transmitted to the L cleaning block through the supporting rod, and the use of two supporting rods on the same side which are in the shape of a right trapezoid realizes the expansion or contraction of the L cleaning block, so that by accurately controlling the rotation of the driving motor two, the brush can be tightly attached to the inner wall of the distillation kettle, and the brush can be in full contact with the inner wall, effectively improving the cleaning effect and avoiding the blind area caused by insufficient contact.

[0027] 2、By setting the rotating assembly, when the driving motor three is started, its output end drives the gear one to rotate, the gear one and the gear two are meshed with each other, thereby driving the gear two to rotate synchronously, the rotation of the gear two is transmitted to the rotating cylinder through the guide rod, so that the rotating cylinder rotates around its own axis, and in the rotating process, because the screw rod two can rotate under the action of external force when the driving motor two is powered off, and there is a friction force between the moving cylinder and the screw rod two, so the rotation of the rotating cylinder can drive the screw rod two, the moving cylinder, and the supporting rod and the L cleaning block connected thereto to rotate together, realizing the rotating cleaning of the inner wall of the distillation kettle, at the same time, by using the characteristics of the clutch motor, the rotating assembly will not affect the position of the outer support assembly when it is working, ensuring that the brush is always attached to the inner wall, and under the premise of maintaining good cleaning contact, the rotating motion can enhance the comprehensiveness and cleaning strength of the cleaning, and improve the cleaning efficiency.

[0028] 3、By setting the water spraying assembly, when the water pump is started, the cleaning liquid in the water tank is pumped into the annular water guide half ring one through the corrugated pipe one, the annular water guide half ring one and the annular water guide half ring two are movably connected through the annular movable ring and the annular movable groove, and the sealing ring is used to ensure the sealing of the connection, the cleaning liquid flows in the annular water guide half ring two, and then is delivered to the water channel inside the L cleaning block through the corrugated pipe two, and finally is uniformly sprayed on the inner wall of the distillation kettle from the nozzle, when the rotating cylinder rotates, the annular water guide half ring two is driven to rotate synchronously through the connecting rod, so that the cleaning liquid can uniformly cover the entire inner wall of the distillation kettle, realizing the function of water spraying without affecting the normal work of the outer support assembly and the rotating assembly, ensuring the attachment of the brush to the inner wall and the continuity of the rotating cleaning during the cleaning process, the combination of water spraying and rotating cleaning can effectively dissolve and flush the residues on the inner wall of the distillation kettle, further improving the cleaning effect, and the automatic water spraying process reduces the manual operation link, improving the convenience and efficiency of the cleaning.

[0029] 4. By setting up a moving component, after the driving motor is started, its output end drives the screw rod to rotate. Since a screw hole corresponding to the screw rod is opened inside the support frame, the rotation of the screw rod enables the support frame to move back and forth along the axial direction of the screw rod. The movement of the support frame drives the rotating cylinder, the outer support component, the rotating component, the water spray component and the L cleaning block connected thereto to move together, thereby realizing the cleaning of any position on the inner wall of the distillation kettle. The cleaning of any position in the distillation kettle can be flexibly adjusted to ensure that every part of the inner wall of the distillation kettle can be cleaned, greatly expanding the cleaning range, avoiding the problem of incomplete cleaning due to the inconvenience of manual operation, ensuring the comprehensive cleaning of the inner wall of the distillation kettle, and improving the quality and production efficiency of menthol preparation.

At this time, the guide rod 605 on the outer wall of the rotating cylinder 4 penetrates through the corresponding guide hole on the moving cylinder 603. The surface of the guide rod 605 is treated by high-precision grinding, and forms precise cooperation with the guide hole of the moving cylinder 603. It not only provides accurate guidance for the movement of the moving cylinder 603, but also can bear a large lateral force to prevent the moving cylinder 603 from deviating or shaking during movement. The movement of the moving cylinder 603 is transmitted to the L cleaning block 5 through the support rod 604 hinged at both ends. The two support rods 604 on the same side form a connecting rod mechanism. When the moving cylinder 603 moves, the connecting rod mechanism stably pushes the L cleaning block 5 to gradually expand outward until the brush 501 at the bottom of the L cleaning block 5 is tightly attached to the inner wall of the distillation kettle. After attachment, the driving motor two 601 is powered off. The clutch motor characteristic makes the output end separate from the screw rod two 602, and the screw rod two 602 no longer drives the moving cylinder 603 to move. The L cleaning block 5 maintains the attached state with the inner wall.

[0061] Next, the water pump 802 is started. It adopts a centrifugal design. The high-speed rotation of the internal impeller generates strong suction, which extracts and pressurizes the cleaning liquid stored in the water tank 801. The pressurized cleaning liquid is transported to the annular water guide half ring one 804 through the corrugated pipe one 803 with excellent flexibility. The annular water guide half ring one 804 and the annular water guide half ring two 805 are movably connected through the annular movable ring 809 and the annular movable groove 810. The contact surface of the two is precisely machined and provided with double-layer fluororubber sealing rings, which can not only prevent the cleaning liquid from leaking, but also allow the annular water guide half ring two 805 to rotate flexibly when the rotating cylinder 4 rotates. After the cleaning liquid is uniformly distributed in the annular water guide half ring two 805, it flows into the water channel 807 inside the L cleaning block 5 through multiple corrugated pipes two 806. The water channel 807 is designed with a flow distribution structure to ensure that the cleaning liquid can be uniformly distributed to each nozzle 808. Finally, the cleaning liquid is uniformly sprayed on the inner wall of the distillation kettle in the form of a fan-shaped mist from the nozzles 808 inside the brush 501, which preliminarily dissolves and washes the residues on the inner wall.

[0062] Subsequently, the driving motor three 701 is powered on, and the output end drives the gear one 702 to rotate. The gear one 702 and the gear two 703 are engaged with each other, the rotating power is stably transmitted to the gear two 703, the gear two 703 synchronously rotates, the outer wall of the gear two 703 is rigidly connected with the rotating cylinder 4 through the guide rod 605, so that the rotating cylinder 4 rotates around its axis, the two supporting rings 704 at the top of the supporting frame 2 are matched with the annular groove 705 of the outer wall of the gear two 703, and small gap matching is adopted between the two, so as to ensure the stability of the gear two 703 in the rotating process, support the rotation and prevent the gear two 703 from shaking or deviating. The rotation of the rotating cylinder 4 drives the L cleaning block 5 installed on the outer wall to rotate together. The brush 501 at the bottom of the L cleaning block 5 wipes the inner wall of the distillation kettle in all directions in the rotating process. Since the driving motor two 601 is in a power-off state, the screw rod two 602 can rotate freely under external force when the rotating cylinder 4 rotates, and the working of the rotating assembly 7 is not hindered, so that the L cleaning block 5 can continuously and stably rotate and clean.

[0063] Finally, the driving motor one 302 is started, and the output end drives the screw rod one 303 to rotate. The screw rod one 303 is matched with the screw hole in the supporting frame 2. The rotation of the screw rod one 303 drives the supporting frame 2 to move along the axial direction of the screw rod one 303. The supporting block 304 at the top of the mounting shell 301 is tightly attached to the bottom of the supporting frame 2. The surface of the supporting block 304 is ground to provide stable support for the movement of the supporting frame 2. The movement of the supporting frame 2 drives the rotating cylinder 4, the L cleaning block 5, the outer supporting assembly 6, the rotating assembly 7 and the water spraying assembly 8 and all other components connected thereto to move together. In the moving process, combined with the rotation of the L cleaning block 5 and the continuous spraying of the water spraying assembly 8, the inner wall of the distillation kettle at all positions is fully and completely cleaned.

[0064] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
