A stirring mechanism 6 is provided on the outer surface of the mechanism 4. Through the cooperation of the driving mechanism 4 and the limiting protrusion 33, the main disk 3 and the stirring mechanism 6 are driven to rise and fall, and power is distributed to drive the stirring mechanism 6 to stir and scrape. During the lifting and lowering of the main disk 3, the unidirectional flow action of the internal circulation mechanism 5 is used to drive the internal fluid to circulate in different areas, and the shape of the stirring mechanism 6 is changed by extrusion to achieve the effect of switching between stirring and scraping. The main disk 3 is used to connect with the gears on the driving mechanism 4, and drive each gear to rise and fall to drive the internal circulation mechanism 5 and the stirring mechanism 6 to rise and fall. During the stirring and scraping process of the stirring mechanism 6, the unmixed residual raw materials will be scraped into the collecting tank 31 for unified storage. After the limiting protrusion 33 is clamped by the driving mechanism 4, it maintains the current height and will not move when not affected by external force.

[0021] The driving mechanism 4 includes a driving motor 41, which is installed inside the motor housing 21. The driving motor 41 is fixedly connected to the inner surface of the reactor cover 2, and the driving motor 41 is placed vertically downward. The output end of the driving motor 41 is fixedly connected to a driving spindle 42 that penetrates into the reactor chamber 1. An engagement groove 421 is provided on the outer surface of the driving spindle 42. A driven bevel gear 43 is sleeved on the outer surface of the driving spindle 42. An inner mounting frame 44 is rotatably connected to the bottom surface of the driven bevel gear 43. An active bevel gear 45 is rotatably connected to the bottom surface of the inner mounting frame 44. An engagement hole 451 that matches the engagement groove 421 is provided on the inner surface of the active bevel gear 45. Both sides of the inner mounting frame 44 are rotatably connected to idler bevel gears 46. One end of the idler bevel gear 46 is fixedly connected to a connecting shaft 461, and the other end of the connecting shaft 461 is fixedly connected to a toggle arm 462. The inner surface of the reactor chamber 1 is fixedly connected to a symmetrically distributed lifting shell 47. The outer surface of the lifting shell 47 is provided with a sliding groove 471. The inner surface of the sliding groove 471 is slidably connected to a push mounting frame 472. The outer surface of the push mounting frame 472 is fixedly connected to equidistantly distributed toggle teeth 4721. The outer surface of the push mounting frame 472 is fixedly connected to a push block 4722. The inner surface of the reactor chamber 1 is fixedly connected to a symmetrically distributed clamping shell 48, and the inner surface of each clamping shell 48 is slidably connected to a symmetrically distributed clamping plate 481. The connection between the clamping plate 481 and the clamping shell 48 A clamping spring 482 is sleeved therein. Through the setting of the driving mechanism 4, during use, the driving motor 41 is started to drive the driving mechanism 4 to rise and fall and the stirring mechanism 6 to stir. The driving motor 41 drives the driving spindle 42 to rotate. Since the driving spindle 42 is only sleeved with the driven bevel gear 43, it will not directly drive it to rotate, but after passing through the driven bevel gear 43, it drives the active bevel gear 45 to rotate through the meshing groove 421 and the meshing hole 451 at the bottom, and the active bevel gear 45 can slide on the driving spindle 42, and the active bevel gear 45 drives the idler bevel gear 46 to rotate, and the idler bevel gear 46 finally drives the driven bevel gear 43 to rotate. In this way, although the active bevel gear 45 and the driven bevel gear 43 are penetrated by the center of the driving spindle 42 at the same time, they rotate in opposite directions. While transmitting the rotation, the toggle arm 462 also rotates itself, and drives the connecting shaft 461 and the toggle arm 462 on both sides to rotate. When the toggle arm 462 rotates, it will contact the toggle tooth 4721 on one side. At this time, the toggle tooth 4721 on this side extends outward, and the toggle arm 462 contacts the inner part of the toggle tooth 4721. Since the toggle tooth 4721 cannot move in the vertical direction, the toggle arm 462 will lift itself up or press it down when it is toggle to the toggle tooth 4721. The toggle arms 462 on both sides are lifted or pressed down at the same time to drive the main plate 3 to achieve lifting and lowering. When the toggle arm 462 rotates one circle, the main plate 3 is lifted and lowered once when it rotates to the side of the extended toggle tooth 4721, and it does not play any role when it rotates to the side where the toggle tooth 4721 is retracted, thereby achieving intermittent lifting and lowering.When the toggle arm 462 moves to the push block 4722, the push block 4722 is higher, and the toggle arm 462 cannot contact the top or bottom of the push block 4722. It can only apply force to the side to push the push block 4722 in and drive the push mounting frame 472 to slide. At this time, the toggle tooth 4721 and the push block 4722 on this side are pushed in, and the toggle tooth 4721 and the push block 4722 on the other side are pulled out. When the toggle arm 462 rotates, it can only contact the toggle tooth 4721 on the newly pulled out side, and at this time the contact surface is opposite to the previous one. For example, when it rotates counterclockwise, it contacts the top of the toggle tooth 4721 on the left side, thereby being lifted up, and when it contacts the bottom of the toggle tooth 4721 on the right side, it is pressed down, and the lifting shell 47 and The clamping shells 48 are arranged in a cross shape. When the lifting shell 47 is lifted, the clamping shells 48 on both sides clamp the limit protrusions 33 through the clamping plates 481 to maintain the current height to prevent slipping. The clamping plates 481 are pushed out by the clamping springs 482 to have a certain movable gap to prevent the surface wear of the clamping plates 481 from reducing the clamping effect after long-term use. The rotation dispersed by the driving main shaft 42 drives the main plate 3 to intermittently reciprocate and lift, and scrapes the residue on the inner wall of the reactor chamber 1 during the lifting process. The stirring blades 65 also follow the lifting of the main plate 3. The active bevel gears 45 and the driven bevel gears 43 respectively drive the upper and lower stirring blades 65 to rotate in opposite directions, forming a more complex flow pattern in the container, thereby improving the uniformity of mixing.

[0022] The driving spindle 42 is rotatably connected to the inner bottom surface of the reaction kettle chamber 1, the inner mounting frame 44 is fixedly connected to the inner surface of the main body plate 3, the driving spindle 42 passes through the inner mounting frame 44, the driven bevel gear 43, the active bevel gear 45 and the idler bevel gear 46 are all slidably connected to the inner surface of the mounting groove 32, the driven bevel gear 43, the active bevel gear 45 and the idler bevel gear 46 are all rotatably connected to the outer surface of the inner mounting frame 44, the number of connecting shafts 461 is two, and the two connecting shafts 461 extend to the lifting The inner surface of the housing 47, the toggle arm 462 is slidably connected to the inner surface of the lifting housing 47, the number of push blocks 4722 on each push mounting frame 472 is two, and the two push blocks 4722 are respectively fixedly connected to the top and bottom ends of the push mounting frame 472, the toggle teeth 4721 and the push blocks 4722 are both slidably connected to the inner surface of the sliding groove 471, and the toggle teeth 4721 and the push blocks 4722 are both slidably connected to the toggle arms 462, and the lifting housing 47 is connected to the clamping housing 47. The housing 48 is arranged in a cross shape, the clamping plate 481 is slidably connected to both sides of the limiting protrusion 33, the active bevel gear 45 and the driven bevel gear 43 are installed at the top and bottom of the inner mounting frame 44, and rotate in the mounting groove 32, so as to follow the lifting of the main plate 3, the inner mounting frame 44 is penetrated by the driving main shaft 42 without affecting the rotation of the driving main shaft 42, and the two sides of the inner mounting frame 44 are rotated to connect the idler bevel gear 46, and also follow the lifting of the main plate 3, the idler bevel gears 46 on both sides turn in the opposite direction and drive the connecting shaft 46 1 is rotated, the extension states of the toggle teeth 4721 on both sides are opposite, so that the main plate 3 can be lifted or pressed down on both sides, and the clamping of the clamping shell 48 is also symmetrical, which disperses the force and limits the moving path to prevent the main plate 3 from deflecting, and pushes the mounting frame 472 to drive the toggle teeth 4721 and the pushing block 4722 to move horizontally, so that only the toggle teeth 4721 on one side are extended to contact with the toggle arm 462 at the same time, and the toggle arm 462 contacts the top or bottom of the toggle teeth 4721 on this side, so as to realize lifting and lowering.

[0023] The inner circulation mechanism 5 includes an inner mounting seat 51, which is fixedly connected to the inner surface of the main body plate 3, and the inner surface of the inner mounting seat 51 is fixedly connected with an inner through groove 52 for fluid to pass through.

One end of the movable rod 53 is fixedly connected with a one-way baffle 531, and the one-way baffle 531 moves with the movable rod 53.

The filter frame 5 The top surface of the filter frame 54 is fixedly connected with a top filter screen 541, and the inner surface of the filter screen frame 54 is provided with a cam groove 542.

The other side is installed at a lower position and can only be opened downward to allow liquid to pass from top to bottom. The top filter screen 541 is installed on this side to control the circulation direction of the internal fluid, and each inner through groove 52 is connected to the one-way baffle 531 by a movable rod 53. The one-way baffle 531 is connected to the inner through groove 52, which can slide. When the one-way baffle 531 covers the inner through groove 52, the inner through groove 52 is blocked and cannot flow. Since the main plate 3 covers the entire interior of the reactor chamber 1, it is equivalent to a piston. When the main plate 3 descends, the bottom liquid will pass through the inner through groove 52 on the side that opens upward, and the other side cannot be opened upward, so that the liquid only passes from one side. When the main plate 3 rises, the liquid only passes from the side that opens downward, and passes through the top filter screen 541 from top to bottom, so that the large particles of solid that are not fully mixed inside will follow the circulation of the liquid and stay on the top filter screen 541, and the When the one-way baffle 531 on the side descends and opens, the movable rod 53 forms a cylindrical cam structure by contacting the ball protrusion 532 and the cam groove 542 of the filter frame 54, driving the filter frame 54 and the top filter 541 to rotate, and the large particles of solid on the surface of the top filter 541 are thrown out to prevent clogging of the top filter 541. After continuous stirring and scraping by the subsequent stirring mechanism 6, the solids are scraped and temporarily stored in the collecting tank 31, which plays a role in controlling the flow direction of the liquid by using the one-way flow structure, and improving the mixing uniformity by using the up and down circulation, and can make the large particles that are not fully mixed be fixed and temporarily stored on the top of the main disk 3, so as to facilitate recovery after the reaction is completed.

The structure of each group of stirring mechanisms 6 is the same. The driven mounting ring 61 on one side of each group close to the main plate 3 is fixedly connected to the driven bevel gear 43 or the active bevel gear 45, and rotates with it. The driven mounting ring 61 on the other side is sleeved on the driving main shaft 42, and can move on the driving main shaft 42 while rotating with it. The two driven mounting rings 61 of each group are pushed open to both sides by the compression spring 63, so that when not affected by external force, the two driven mounting rings 61 will stay away from each other. The upper and lower rotating arms 62 are separated and driven to be pulled apart. The longitudinal dimension of the rotating arm 62 and the connecting arm 621 as a whole increases, while the lateral dimension decreases, tending to be trapezoidal. The hinged outer column 641 and the connecting inner column 642 are also pulled apart. Since the stirring blade 65 is connected to the middle of the hinged outer column 641 on one side, the upper and lower stirring blades 65 are also pulled apart and tilted, which is more suitable for stirring. The stirring directions of the upper and lower two groups of stirring mechanisms 6 are opposite, which can form a more complex flow pattern of the material in the container, with both axial circulation and radial mixing, thereby improving the uniformity of mixing and effectively preventing the material from being excessively accumulated or retained in a certain area. Especially for materials with high viscosity or large density differences, the overall mixing can be better achieved. As the main plate 3 rises or falls, The top driven mounting ring 61 will contact the inner blocking frame 66, or the bottom driven mounting ring 61 will contact the inner bottom surface of the reactor chamber 1, and both will compress the two driven mounting rings 61 of each group, so that the distance between the upper and lower rotating arms 62 is reduced, and the overall longitudinal dimension of the rotating arm 62 and the connecting arm 621 is reduced, and the lateral dimension is increased, tending to a rectangle, until it is fully compressed. The rotating arm 62 is perpendicular to the driving spindle 42 and completely covers the surface of the main body disk 3 or the inner bottom surface of the reactor chamber 1, and the connecting arm 621 will stick to the inner wall of the reactor chamber 1 as the lateral dimension increases. At this time, the stirring mechanism 6 is more suitable for scraping off the residues attached to the surface of the reactor chamber 1 and the main body disk 3 to prevent stirring accumulation. As the main body disk 3 intermittently rises and falls,The stirring and ash scraping of the upper and lower stirring mechanisms 6 work in turn.

The stirring blades 65 are respectively installed in the middle of the hinged outer columns 641 on both sides. When the connecting arm 621 rotates, the hinged outer column 641 is stuck on the connecting groove 6421 of the connecting inner column 642 through the connecting protrusion 6411 and can be staggered and slid to increase the length. The fixed connecting column 64 and the hinged outer column 641 can rotate to adapt to different angles after the rotating arm 62 rotates, and the connecting inner column 642 and the hinged outer columns 641 on both sides are always vertically downward for installing the stirring blades 65.

The connecting protrusion 6411 is slidably connected to the inner surface of the connecting groove 6421 to drive the hinged outer column 641 to slide on the connecting inner column 642. The inner blocking frame 66 is slidably connected to the top rotating arm 62. The inner bottom surface of the reactor chamber 1 is slidably connected to the bottom rotating arm 62. The hinged outer column 641 and the connecting inner column 642 both penetrate the stirring blade 65.
