[0038] The mixing tank 10 further includes a filter structure 30 , which is disposed on the top of the mixing tank 10 and is located below the cover 20 . The filter structure 30 connects the first feeding port 11 and the second feeding port 21 when the cover 20 is closed.

[0039] Specifically, the stirring member 12 is a stirring rod, which is driven to rotate by a motor; the cover body 20 and the mixing tank 10 can be locked with each other through a lock (not shown in the figure);

[0040] The filtering structure 30 disposed between the second feeding port 21 and the second feeding port 21 can filter the added raw material liquid while injecting it into the mixing chamber, thereby removing impurities in the raw material liquid and ensuring the purity of the reaction system to make it more in line with quality standards; there is no need to add additional processing steps before the reaction, which simplifies the process flow and improves the preparation efficiency.

[0041] like Figure 4 , Figure 5 , Figure 6 As shown, Figure 4 It shows Figure 2 Middle partial schematic diagram; Figure 5 Shown is a schematic diagram of the feeding port 1 in the embodiment (top view); Figure 6 What is shown is a schematic diagram of the filtering structure in the embodiment (top view);

[0042] The filtering structure 30 includes a mounting groove 31 opened on the top of the mixing tank 10, and a movable rod 32 is rotatably provided in the middle part of the mounting groove 31. Four connecting rings 33 are fixedly provided on the side wall of the movable rod 32 through a connecting rod.

[0043] The movable rod 32 is rotated to connect the first feeding port 11 and the second feeding port 21 through the connecting ring 33, so that the raw materials are allowed to pass through, and the filter screen 34 filters the raw materials.

[0044] The movable rod 32 is rotatably inserted in the installation groove 31. By rotating the movable rod 32, the connecting ring 33 can be rotated to the corresponding feeding port 11 below, so that the two are connected. After closing the cover body 20, the feeding port 21, the connecting ring 33, and the feeding port 11 are connected. The inner cavity between the three can allow the raw material liquid to pass through. At this time, the filter screen 34 set in the connecting ring 33 can filter the raw material liquid.

[0045] Four connecting rings 33 are provided, and the filter screen 34 is detachably connected to the connecting ring 33. The filter screens 34 with different mesh diameters can be installed in the connecting ring 33. The corresponding connecting ring 33 can be rotated to the feeding port 11 and the feeding port 21 as needed. The filter screen 34 can also be not installed in the two opposite connecting rings 33 to facilitate fixing or adding other raw materials that do not need to be filtered;

[0046] When the cover 20 is opened, the movable rod 32 can be manually rotated to change the position of the connecting ring 33, so as to select the corresponding connecting ring 33 and filter screen 34 for filtering.

[0047] like Fig.10 As shown, Fig.10 Shown is a schematic diagram of the matching of the connecting ring and the filter screen;

[0048] Specifically, a step surface for the filter screen 34 to be inserted into is provided on the inner side of the connecting ring 33 . The filter screen 34 includes a mounting cylinder 341 and a mesh portion 342 . The mounting cylinder 341 is mounted on the step surface, and the mesh portion 342 closes the bottom of the mounting cylinder 341 .

[0049] The step surface is provided to play the role of detachable installation of the filter screen 34. During installation, the installation cylinder 341 is inserted into the interior of the connecting ring 33. After the cover body 20 is subsequently closed, the filter screen 34 is fixed at the same time.

[0050] like Figure 5 , Figure 6 , Figure 8 , Fig. 9 , Figure 5 Shown is a schematic diagram of the feeding port 1 in the embodiment (top view); Figure 6What is shown is a schematic diagram of the filtering structure in the embodiment (top view); Figure 8 It shows Figure 6 A schematic diagram of the enlarged structure in the middle; Fig. 9 It shows Figure 4 Schematic diagram of the enlarged structure at B in the middle;

[0051] The guide assembly 40 includes an annular guide plate 41 coaxially arranged with the mounting groove 31, a guide groove 42 is formed on one end of the annular guide plate 41 close to the connecting ring 33, an elastic guide rod 43 is provided on one end of the connecting ring 33 away from the movable rod 32, and the elastic guide rod 43 is slidably matched with the guide groove 42;

[0052] The locking assembly 50 is also included. The locking assembly 50 includes limiting holes 51 arranged on the annular guide plate 41 at positions on both sides of the feeding port 11. A screw 53 is movably inserted into the limiting hole 51. The screw 53 is arranged on a side of the limiting hole 51 away from the connecting ring 33. A nut 52 is also arranged on the side of the annular guide plate 41 away from the connecting ring 33 and corresponding to the position of the limiting hole 51. The screw 53 is threadedly matched with the nut 52.

[0053] By setting up a slidingly matched elastic guide rod 43 and a guide groove 42, when the movable rod 32 rotates, the connecting ring 33 can be rotated and adjusted in a fixed path, and the stability during the rotation process can be increased; by setting up a locking component 50, the corresponding connecting ring 33 can be rotated to the position of the connecting feeding port 11 and stopped and locked by adjusting the locking component 50, so as to ensure the accuracy of the connecting position of the connecting ring 33 and ensure that the material can pass smoothly.

[0054] Specifically, Figure 7 As shown, Figure 7 What is shown is a schematic diagram of the structure of the connecting ring and the elastic guide rod; the elastic guide rod 43 includes a fixed rod 431, and the end of the fixed rod 431 away from the connecting ring 33 is sequentially provided with an inner rod 432 and a sleeve block 433, the sleeve block 433 is movably sleeved on the end of the inner rod 432, and the two are slidably matched, and a spring 434 is also sleeved on the outside of the inner rod 432, and the two ends of the spring 434 are respectively connected to the sleeve block 433 and the fixed rod 431.

[0055] When the connecting ring 33 is in a rotatable state, the elastic guide rods 43 are all located in the guide grooves 42, and the springs 434 between the sleeve block 433 and the fixed rod 431 are in a compressed state, that is, the sleeve block 433 has a tendency to extend outwards but does not affect the rotation of the sleeve block 433 in the guide groove 42; at the same time, the screw rod 53 blocks the limiting hole 51, and the sleeve block 433 cannot enter the limiting hole 51;

[0056] When the connecting ring 33 is locked, the screw 53 is screwed outward, and when the sleeve 433 rotates in the guide groove 42 to the position of the limit hole 51, the sleeve 433 will be pushed into the limit hole 51 under the action of the spring 434. At this time, the position of the sleeve 433 will be locked and cannot continue to rotate; the connecting ring 33 is locked in the correct position connected with the feeding port 11;

[0057] The locking assembly 50 cooperates with the guide assembly 40 to achieve accurate positioning and locking of the connecting position of the connecting ring 33 .

[0058] When the position of the connecting ring 33 needs to be adjusted again, the screw rod 53 can be rotated to gradually contact the sleeve block 433, and the sleeve block 433 slides at the end of the inner rod 432 and compresses the spring 434 until the sleeve block 433 is pushed out of the limiting hole 51 and enters the guide groove 42, and then the connecting rings 33 can be rotated again to adjust the position through external force.
