[0038] The motor 702 can drive the first telescopic rod 703, the second telescopic rod 707, and the third telescopic rod 711 to expand and contract, and can move up and down inside the reaction kettle body 1. By inputting high-pressure cleaning medium into the transmission shaft and finally spraying it out through the through holes 715a of the cleaning ball 715, the inside of the reaction kettle can be cleaned at different heights. In some embodiments, the first telescopic rod 703, the second telescopic rod 707, and the third telescopic rod 711 can be semi-closed structures with openings at one end, and the cross-section can be rectangular.

The structures of the first transmission shaft 705, the second transmission shaft 709, and the third transmission shaft 714 are the same. The structures of the first connecting shaft 706 and the second connecting shaft 710 can be the same.

[0040] Taking the second transmission rod 708 as an example, as Figure 4As shown, the periphery of the second transmission rod 708 may have threads and a limit groove 709a. A limit rod 709b may be provided in the inner cavity of the second telescopic rod 707.

When the cleaning motor 702 operates, the first transmission shaft 704 rotates, and then drives the first transmission shaft 705 to rotate downward or upward, thereby causing the second telescopic rod 707 to extend downward or upward. The limit groove on the periphery of the first transmission rod 704 is engaged with the limit rod 709b in the second transmission rod 708 to drive the second transmission rod 708 to rotate. The rotation of the second transmission rod 708 can also cause the third telescopic rod 711 to extend downward or upward, thereby driving the cleaning ball 715 to rotate and clean.

[0041] As Figure 5 shown, the first connecting shaft 706 includes a first connecting shaft body 706a and a snap ring 706b located on the inner side wall of the first connecting shaft 706. The snap ring 706b is clamped at the clamping groove 709c.

[0042] The easily cleanable chemical production reactor includes a connecting pipe 6. The cleaning mechanism 7 can be accommodated in the connecting pipe 6. The bottom of the connecting pipe 6 can be fixed to the top of the sealing cover 2.

Specifically, the sealing mechanism 8 can be a gate valve. The gate valve can include a valve body 81. The valve body 81 is connected to the connecting pipe 6. The sealing mechanism 8 includes a gate plate 82 and a valve stem 83. The valve stem 83 can be connected to the gate plate 82. The valve stem 83 can move to drive the gate plate 82 to close the channel in the connecting pipe 6. The gate valve is a prior art and will not be described in detail here.

[0044] After the cleaning mechanism 7 finishes cleaning, the lifting of the cylinder 5 can cause the cleaning mechanism 7 to retract into the connecting pipe 6. At this time, the sealing mechanism 8 can be closed, and the reactor can carry out the next round of reaction.

[0045] Therefore, the present invention effectively overcomes various disadvantages in the prior art and has high industrial utilization value. The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention.
