[0026] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please see Figures 1-4 As shown, this utility model is an auxiliary stirring device for a mixing vessel, including a vessel body 1, a top cover 2, and a controller 3. A first connecting flange 101 is welded to the upper surface of the vessel body 1, and a second connecting flange 216 is welded to the lower surface of the top cover 2. The second connecting flange 216 is disposed on the upper surface of the first connecting flange 101. The controller 3 is installed on the upper surface of the top cover 2. Sliding rods 201 are slidably installed at both ends of the upper surface of the top cover 2. The two sliding rods 201 penetrate the upper surface of the top cover 2 and extend into the interior of the vessel body 1. A sliding plate 202 is welded to the lower surface of the two sliding rods 201. The sliding plate 202 is an annular plate. The structure includes a sliding plate 202 with several placement slots 203 on its upper surface. Each placement slot 203 has a rotatable connecting shaft 204. Several auxiliary stirring plates 205 are welded to the circumference of the connecting shaft 204. This allows the sliding rod 201 to be raised and lowered simultaneously with the movement of the lead screw nut 210 controlled by the drive motor 209. This causes the sliding plate 202 to slide up and down inside the vessel body 1. Furthermore, the movement of the sliding plate 202 up and down causes the auxiliary stirring plates 205 to rotate due to the flow of liquid inside the vessel body 1, thereby improving the stirring efficiency of the vessel body 1 and its working efficiency.

[0028] The sliding plate 202 is slidably connected to the inner wall of the vessel body 1. Two mounting blocks 206 are also welded to the upper surface of the top cover 2. The two mounting blocks 206 are respectively set on one side of the sliding rod 201. Each of the two mounting blocks 206 has a mounting groove 207 on one surface. A ball screw 208 is rotatably installed inside each of the two mounting grooves 207.

[0029] Two drive motors 209 are fixedly mounted on the upper surfaces of the two mounting blocks 206. One end of each of the two ball screws 208 extends to the outside of the mounting block 206, and the output ends of the two drive motors 209 are connected to the keyways of one end of each of the two ball screws 208.

[0030] The two drive motors 209 are electrically connected to the controller 3. The two ball screws 208 have screw nuts 210 threaded on their circumferences. The two screw nuts 210 are slidably connected to the mounting grooves 207. A connecting plate 211 is welded to one surface of each screw nut 210. The two connecting plates 211 are welded to the upper surfaces of the two sliding rods 201 respectively.

[0031] A stirring motor 212 is also installed on the upper surface of the top cover 2. The stirring motor 212 is electrically connected to the controller 3. The output end of the stirring motor 212 is connected to the stirring shaft 213 via a keyway.

[0032] The stirring shaft 213 passes through the upper surface of the top cover 2 and extends into the interior of the vessel body 1. Several stirring blades 214 are welded to the circumferential side of the stirring shaft 213. The stirring blades 214 are arranged in the inner ring of the sliding plate 202.

[0033] The top cover 2 has an inlet 215 on its upper surface and an outlet 102 on its lower surface. One end of the outlet 102 is connected to the inside of the vessel body 1, and a control valve 103 is installed on the circumferential side of the other end of the outlet 102. The control valve 103 is electrically connected to the controller 3. Support columns 104 are welded to the circumferential side of the lower surface of the vessel body 1.

[0034] Several fixing bolts 4 are installed between the first connecting flange 101 and the second connecting flange 216. One end of the fixing bolt 4 extends to the bottom of the first connecting flange 101, and a fixing nut 5 is screwed to the lower end of the fixing bolt 4.

[0035] Please see Figures 1-4 As shown, this utility model is an auxiliary stirring device for a mixing vessel. Its usage is as follows: First, the controller 3 simultaneously starts two drive motors 209, causing two ball screws 208 to rotate at the same frequency. When the ball screws 208 rotate, they drive the screw nut 210 to move. Controlling the forward and reverse rotation of the drive motors 209 causes the screw nut 210 to move up and down. When the screw nut 210 moves, it drives the sliding rod 201 to move up and down inside the vessel body 1, thereby causing the sliding plate 202 to slide up and down inside the vessel body 1. Furthermore, as the sliding plate 202 moves up and down, the flow of liquid inside the vessel body 1 causes the auxiliary stirring plate 205 to rotate, stirring the contents inside the vessel body 1. Simultaneously with the start of the drive motors 209, the controller 3 also starts the stirring motor 212. The stirring motor 212 drives the stirring shaft wall 213 and the stirring blades 214 to rotate, stirring the contents inside the vessel body 1.
