Technical Field

[0001] This utility model relates to the field of stirred tank technology, specifically to an anti-eccentric stirred tank for the production of bispyribac-sodium. Background Technology

[0002] In industrial production, especially in the chemical production field, stirred tanks are widely used in the mixing process. In addition to mixing materials evenly, they also enhance heat and mass transfer, accelerate the reaction in the stirred tank and make the reaction complete. Stirred tanks are required in the production process of bispyribac-sodium.

[0003] The existing stirred tanks used for bispyribac-sodium production have the following drawbacks during use: because the blades are fixed at the far end of the shaft, they are prone to eccentric operation during stirring, causing vibration of the stirred tank and affecting its stable operation. Therefore, there is room for improvement. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0018] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example

[0019] Combination Figure 1-5 As shown, this embodiment provides an anti-eccentric stirring vessel for the production of bispyribac-sodium, comprising: a main body 100 and a stirring mechanism 200.

[0020] The main structure 100 includes a vessel body 110, a feed pipe 120 installed at the top of the vessel body 110, a discharge pipe 130 fixed at the bottom of the vessel body 110, and an electric valve 140 installed on the discharge pipe 130.

[0021] The vessel body 110 serves as a container for holding materials that need to be stirred. The feed pipe 120 is used to introduce materials into the inner cavity of the vessel body 110. The discharge pipe 130 is used to discharge the materials after stirring. The electric valve 140 is used to control the opening and closing of the discharge pipe 130.

[0022] The stirring mechanism 200 is used to stir materials and includes a base 210 fixed to the top of the vessel body 110, a U-shaped seat 220 with its end slidably fitted onto the base 210, a threaded sleeve 230 fixed to one side of the U-shaped seat 220 and extending into the inner cavity of the base 210, a first driving member 240 installed in the inner cavity of the base 210 and passing through the threaded sleeve 230, a first stirring member 250 with its top end rotatably connected to the end of the U-shaped seat 220 and its bottom end extending into the inner cavity of the vessel body 110, a second stirring member with its top end rotatably connected to the other end of the U-shaped seat 220 and passing through the first stirring member 250 and extending into the inner cavity of the vessel body 110, and a second driving member 270 fixed on the inner side of the U-shaped seat 220 and meshing with both the first stirring member 250 and the second stirring member 260.

[0023] Both sides of the base 210 are fixed with round rods 212. Sleeves 222 are symmetrically fixed on the U-shaped seat 220. The sleeves 222 are slidably sleeved on the round rods 212 to ensure the stability of the U-shaped seat 220 when it moves up and down. A groove 211 is opened on one side of the base 210. One end of the threaded sleeve 230 is fixed on the U-shaped seat 220, and the other end is fitted into the groove 211. The first driving member 240 includes a threaded rod 241 rotatably installed on the inner wall of the groove 211 and a shaft fixed to the top of the base 210 and the threaded rod. The first motor 242 is fixedly connected to the end of 241. At the same time, the threaded rod 241 passes through the threaded sleeve 230, and the threaded rod 241 and the threaded sleeve 230 mesh with each other. When the first motor 242 starts, it drives the threaded rod 241 to rotate. The rotation of the threaded rod 241 drives the threaded sleeve 230 to move. The movement of the threaded sleeve 230 causes the U-shaped seat 220 to move up and down, thereby driving the first stirring component 250 and the second stirring component 260 to move up and down, so as to facilitate the stirring of materials at different heights in the vessel body 110.

[0024] Bearings 221 are fixed to both ends of the U-shaped base 220. The first stirring component 250 includes a first rotating shaft 251 whose top end is fixed to the inner ring of the bearing 221 at the end of the U-shaped base 220 and extends into the inner cavity of the vessel body 110; a first stirring blade 252 fixed in a ring array at the bottom end of the first rotating shaft 251; and a first bevel gear 253 fixedly sleeved on the top end of the first rotating shaft 251. Meanwhile, the second stirring component 260 includes a second rotating shaft 261 whose top end is fixed to the inner ring of the bearing 221 at the other end of the U-shaped base 220 and extends into the inner cavity of the vessel body 110 through the first rotating shaft 251; a second stirring blade 262 fixed in a ring array at the bottom end of the second rotating shaft 261; and a second bevel gear 263 fixedly sleeved on the top end of the second rotating shaft 261. In addition, the second driving component 270 includes a component fixed to the inner side of the U-shaped base 220. The second motor 271 and the third bevel gear 272 fixed on the shaft of the second motor 271 are meshed with the first bevel gear 253 and the second bevel gear 263. With this arrangement, when the second motor 271 starts, it drives the third bevel gear 272 to rotate. The rotation of the third bevel gear 272 drives the first bevel gear 253 and the second bevel gear 263 to rotate in opposite directions. The first bevel gear 253 rotates clockwise, which drives the first stirring blade 252 to rotate clockwise through the first rotating shaft 251. The second bevel gear 263 rotates counterclockwise, which drives the second stirring blade 262 to rotate counterclockwise through the second rotating shaft 261. The first stirring blade 252 and the second stirring blade 262 rotate in opposite directions, and their rotational eccentric forces cancel each other out, ensuring the stability of the vessel body 110.

[0025] The working principle and usage process of this utility model are as follows: During use, the second motor 271 starts, driving the third bevel gear 272 to rotate. The rotation of the third bevel gear 272 drives the first bevel gear 253 and the second bevel gear 263 to rotate synchronously in opposite directions. The rotation of the first bevel gear 253 drives the first stirring blade 252 to rotate clockwise via the first rotating shaft 251, and the rotation of the second bevel gear 263 drives the second stirring blade to rotate counterclockwise via the second rotating shaft 261. The rotational eccentric forces of the first stirring blade 252 and the second stirring blade 262 cancel each other out, ensuring the stability of the vessel body 110. Simultaneously, the first motor 242 starts, driving the threaded rod 241 to rotate. The rotation of the threaded rod 241 drives the threaded sleeve 230 to move. The movement of the threaded sleeve 230 drives the U-shaped seat 220 to move up and down. The movement of the U-shaped seat 220 drives the first stirring element 250 and the second stirring blade to move up and down, that is, drives the first stirring blade 252 and the second stirring blade 262 to move up and down, thus fully stirring the materials at different heights within the vessel body 110.
