[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, through the cooperation between the stirring motor, stirring shaft, upper cylinder, sleeve frame and lower cylinder, facilitates the rotation of the upper blade, middle blade and lower blade, so that the blades of different layers cooperate with each other to form a three-dimensional mixing effect.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] Example 1, by Figures 1-7 The present invention relates to an improved mixing structure extraction vessel, comprising a vessel body 1, a discharge pipe 8 fixedly connected to the bottom of the vessel body 1, a feed hopper 4 fixedly connected to the top of the vessel body 1, a stirring mechanism 2 provided on the vessel body 1, and a driving mechanism 3 provided on the stirring mechanism 2.

[0031] In Example 2, based on Example 1, the stirring mechanism 2 includes a frame 201 fixed to the top of the vessel body 1. A stirring motor 202 is fixedly mounted on the frame 201, and a stirring shaft 203 is fixedly connected to the stirring motor 202. The bottom end of the stirring shaft 203 extends into the interior of the vessel body 1. From top to bottom, an upper cylinder 204, a sleeve 205, and a lower cylinder 206, all located inside the vessel body 1, are fixedly connected to the outer side of the stirring shaft 203. Multiple upper blades 209 are fixedly connected to the outer side of the upper cylinder 204. The upper blades 209 are wide, straight blades that can generate a large radial force when rotating, quickly pushing the liquid outwards and expanding the mixing range. Multiple... The lower impeller 207 is a narrow, long straight blade designed to generate a strong axial flow, lifting the liquid at the bottom and ensuring full mixing of the liquid within the vessel 1. Multiple side frames 2010 are fixedly connected at equal angles to the outer side of the sleeve frame 205. An inner shaft 2015 is rotatably connected to the inner side of each side frame 2010. A sleeve block 2014 is fixedly fitted to the outer side of the inner shaft 2015. An intermediate impeller 208 is fixedly connected to the outer side of the sleeve block 2014. The intermediate impeller 208 is an oblique blade; this shape provides radial flow while generating a certain amount of axial flow, promoting vertical circulation of the liquid. An L-shaped round rod 2017 is fixedly connected between the top of the side frame 2010 and the outer side of the sleeve frame 205. A slider 2016 is movably sleeved on the outer side of the cylindrical rod 2017. A diagonal rod 2013 is rotatably connected to the outer side of the slider 2016. The bottom end of the diagonal rod 2013 is rotatably connected to the sleeve block 2014. A connecting column 2011 is fixedly connected to the top of the slider 2016, and a top ring 2012 is fixedly connected to the top of the connecting column 2011. The interior of the vessel body 1 is divided into three regions: the upper impeller 209, the middle impeller 208, and the lower impeller 207 are located within these three regions respectively. The liquid experiences different mixing intensities and flow patterns in different regions, gradually transitioning from an initial rapid mixing zone to a fine mixing zone, ultimately achieving a highly uniform mixing effect. Temperature sensors are installed in all three regions. The system accurately monitors the liquid temperature inside vessel 1 to ensure the extraction process occurs within a suitable temperature range, preventing temperature fluctuations from affecting the extraction effect. Vessel 1 is also equipped with a pressure sensor and a concentration sensor. The pressure sensor monitors pressure changes within vessel 1 to ensure safe operation, while the concentration sensor detects the solute concentration in the extract in real time, providing accurate data feedback to the operator. When the temperature exceeds the preset range, the system automatically activates heating or cooling devices for temperature control. If the pressure is abnormal, the system will promptly take pressure-reducing measures. During the mixing process, based on information from the concentration sensor, the system can automatically adjust the stirring speed and impeller angle to achieve the best extraction effect.

[0032] First, the stirring motor 202 is started, which drives the stirring shaft 203 to rotate, and drives the upper cylinder 204, the sleeve frame 205 and the lower cylinder 206 to rotate. At the same time, the upper blade 209, the middle blade 208 and the lower blade 207 rotate. The blades at different levels cooperate with each other to form a three-dimensional mixing effect, which greatly improves the mixing efficiency compared with traditional stirring blades. When the top ring 2012 rises and falls, the connecting column 2011 drives the slider 2016 to slide along the L-shaped round rod 2017, and the inclined rod 2013 drives the sleeve block 2014 and the inner shaft 2015 to rotate. At the same time, the middle blade 208 rotates to adjust the tilt angle. Finally, the vessel body 1 can adapt to various materials from low viscosity to high viscosity and from easy to mix to difficult to mix.

[0033] In Example 3, based on Example 1, the driving mechanism 3 includes two columns 301 symmetrically fixed to the top wall of the vessel body 1. A lifting plate 309 is movably sleeved between the two columns 301. Two side rings 3010 are symmetrically fixed to the outer side of the lifting plate 309. A top ring 2012 is located between the two side rings 3010. Multiple limiting rods 3012 are fixedly connected at equal angles to the top and bottom of the top ring 2012. Each limiting rod 3012 has a ball bearing 3011 at the end away from the top ring 2012. The upper and lower sets of ball bearings 3011 respectively abut against the sides of the two side rings 3010 that are close to each other. By setting the ball bearings 3011 and the limiting rods 3012, direct contact between the top ring 2012 and the side rings 3010 is avoided, thereby reducing the friction force on the top ring 2012 when it rotates. The interior of the vessel body 1 is symmetrically fixed. Two L-shaped round rods 303 are connected, and a sliding plate 308 is movably sleeved between the two L-shaped round rods 303. The bottom of the sliding plate 308 is rotatably connected to a movable rod 302. The bottom end of the movable rod 302 is rotatably connected to the outside of the lifting plate 309. The inside of the vessel body 1 is provided with a chassis 305. The bottom of the chassis 305 is rotatably connected to a drive rod 304. The end of the drive rod 304 away from the chassis 305 is rotatably connected to the bottom of the sliding plate 308. The top of the chassis 305 is fixedly connected to a drive shaft 306. The top of the vessel body 1 is provided with two sealed bearings. The two sealed bearings are respectively sleeved on the outside of the stirring shaft 203 and the drive shaft 306 to ensure the sealing of the vessel body 1. The top end of the drive shaft 306 extends to the outside of the vessel body 1 and is fixedly installed with a drive motor 307. The drive motor 307 is fixed on the frame 201.

[0034] First, start the drive motor 307, which drives the drive shaft 306 to rotate and the chassis 305 to rotate. The drive rod 304 drives the slide plate 308 to slide along the two L-shaped round rods 303. Then, the movable rod 302 drives the lifting plate 309 to slide along the two columns 301. Then, the two side rings 3010 drive the top ring 2012 to rise and fall. Finally, the tilt angle of the middle blade 208 is adjusted.

[0035] In Example 4, based on Example 1, multiple baffles 7 are fixedly connected at equal angles on the inner sidewall of the vessel body 1, and a bracket 5 is fixedly installed on the inner top wall of the vessel body 1. Multiple guide plates 6 are fixedly connected at equal angles at the bottom of the bracket 5.

[0036] By setting the guide plate 6 to guide the liquid to flow in a specific direction, the liquid is prevented from forming an ineffective vortex zone near the stirring shaft 203, thereby improving the utilization efficiency of stirring energy. Furthermore, by setting the baffle plate 7 to change the flow direction of the liquid, the liquid forms a complex zigzag flow path within the vessel 1, further increasing the mixing opportunities between liquids.
