The reaction barrel portion 102 has a stirring chamber 1021. The reaction barrel portion 102 is connected with two connecting pipes 16. Both connecting pipes 16 are provided with a control valve b12. The discharge pipe portion 103 is provided with a control valve a11. The temperature control component is arranged in the stirring chamber 1021. The stirring chamber 1021 is cylindrical. The two connecting pipes 16 are respectively located on the upper and lower sides of the outer circumferential surface of the reaction barrel portion 102.

[0021] The temperature control component includes an outer temperature control ring 13 arranged on the inner surface of the stirring chamber 1021 and a plurality of inner temperature control blocks 14 arranged along a ring shape. The outer temperature control ring 13 is connected to the plurality of inner temperature control blocks 14. Two connecting pipes 16 are connected to the outer temperature control ring 13. Two pipes are connected between the outer temperature control ring 13 and the plurality of inner temperature control blocks 14, one of which is a water inlet pipe a and the other is a water outlet pipe b.

[0022] The reaction cylinder 102 is connected to the water inlet pipe 104. A plurality of water outlet blocks 15 are arranged in a ring shape on the inner wall of the reaction cylinder 102. The plurality of water outlet blocks 15 are all connected to the water inlet pipe 104. The reaction cylinder 102 has a water passage cavity connected to the water inlet pipe 104 and the plurality of water outlet blocks 15. A control valve b12 is arranged on the reaction cylinder 102.

[0023] When this embodiment is used, the worker sends the liquid with the same temperature as required by the polyether reaction to the outer temperature regulating ring 13 and the inner temperature regulating block 14 through the connecting pipe 16 until the liquid adjusts the temperature of the outer temperature regulating ring 13 and the inner temperature regulating block 14 to the temperature required by the user, and then pours the polyether material into the reaction cylinder 102 through the feeding pipe 101 until the amount of material reaches the user's requirement. After the feeding pipe 101 is closed, the stirring assembly stirs the material to accelerate the speed of the polyether reaction. After the polyether reaction is completed, the compound flows out through the discharge pipe 103, and the cleaning liquid flows into the water passage cavity through the water inlet pipe 104. After the water passage cavity is filled, the liquid will overflow to multiple water outlet blocks 15, and the cleaning liquid will clean the residual compounds inside the reactor, thereby reducing the work intensity of the workers.
