For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] See Figures 1 to 3, the present utility model provides a chemical safety reactor, including a reactor body 1 (the structure of the reactor body 1 is the same as that of the prior art, and its specific structure and working principle, such as the structures of the feed inlet and the discharge outlet, etc., will not be elaborated here). A rotating rod 2 is rotatably connected inside the reactor body 1. The top end of the rotating rod 2 penetrates through the reactor body 1 and is connected to the output shaft of a driving member 21. The driving member 21 is connected to the reactor body 1, and the driving member 21 can drive the rotating rod 2 to rotate. A stirring rod 3 is sleeved outside the rotating rod 2. The stirring rod 3 is rotatably connected to the reactor body 1. A driven bevel gear 31 is sleeved on the stirring rod 3, and the driven bevel gear 31 can drive the stirring rod 3 to rotate. The driven bevel gear 31 meshes with a driving bevel gear 32. One side of the driving bevel gear 32 is connected to the output shaft of a driver 321. The driver 321 is connected to the reactor body 1, and the driver 321 can drive the driving bevel gear 32 to rotate. A number of main stirring paddles 33 are symmetrically arranged on the stirring rod 3. When the driver 321 is turned on, the driver 321 drives the driving bevel gear 32 to rotate, the driving bevel gear 32 drives the driven bevel gear 31 to rotate, and the driven bevel gear 31 drives the stirring rod 3 to rotate, so that the stirring rod 3 drives a number of main stirring paddles 33 to rotate, thereby stirring the materials in the reactor body 1.

[0023] See Figures 1 to 3 , the bottom end of the stirring rod 3 is located above the bottom end of the rotating rod 2 (that is, the lower part of the rotating rod 2 is exposed outside and is not blocked by the stirring rod 3). An elevating block 4 is sleeved outside the lower part of the rotating rod 2 (that is, the part not blocked by the stirring rod 3). The elevating block 4 is threadedly connected to the rotating rod 2. A number of limiting rods 5 penetrate through the elevating block 4, and the limiting rods 5 are all connected to the reactor body 1. The limiting rods 5 do not affect the movement of the stirring rod 3 and the main stirring paddles 33 (that is, the top ends of the limiting rods 5 are located below the bottom end of the stirring rod 3). A number of extension rods 6 are rotatably connected to the outer periphery of the elevating block 4. A number of chutes cooperating with the extension rods 6 are provided on the inner wall of the reactor body 1.

When the feeding of the material in the reactor body 1 is completed, the driving member 21 is started, the driving member 21 drives the rotating rod 2 to rotate, and the lifting block 4 moves up and down on the rotating rod 2. As a plurality of extension rods 6 move up and down, the spur gear 61 cooperates with the rack 7, thereby driving a plurality of extension rods 6 to rotate synchronously, and using a plurality of auxiliary stirring paddles 62 to form a turbulent flow at the inner bottom of the reactor body 1 to prevent the material from accumulating at the bottom of the reactor body 1.

[0027] The utility model provides a chemical safety reactor, including a main stirring paddle and an auxiliary stirring paddle. The main stirring paddle can slowly stir the material in the reactor body after the material is introduced into the reactor body, ensuring that the material in the reactor is evenly mixed; as a plurality of extension rods move up and down, the spur gear cooperates with the rack, thereby driving a plurality of extension rods to rotate synchronously, and using a plurality of auxiliary stirring paddles to form a turbulent flow at the inner bottom of the reactor body to prevent the material from accumulating at the bottom of the reactor body and improving the reaction efficiency. In summary, the beneficial effect of the utility model is: it can prevent the material from accumulating at the bottom of the reactor and improve the reaction efficiency on the premise of ensuring that the material in the reactor is evenly mixed.
