DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment discloses a silk fibroin reaction device, including an outer cylinder 1, an outer cover 2, an inner cylinder 3, and a stirring device 4. The outer cylinder 1 has an opening at the upper end, and the outer cover 2 is installed at the upper end opening of the outer cylinder 1. The outer cylinder 1 and the outer cover 2 are connected by a flange. The outer cylinder 1 is provided with a feed hopper 11, and the feed hopper 11 is installed on the side wall of the outer cylinder 1. The connection between the feed hopper 11 and the outer cylinder 1 is located above the inner cylinder 3. The silk raw material can be fed into the inner cylinder 3 from the feed hopper 11. The outer cover 2 is provided with a liquid inlet pipe 5, which is connected to the interior of the outer cylinder 1, and the liquid inlet pipe 5 is used to feed the reagent into the inner cylinder 3.

[0024] The inner cylinder 3 is fixedly installed inside the outer cylinder 1. The inner wall of the outer cylinder 1 is provided with an annular shoulder 15. The upper end opening of the inner cylinder 3 is provided with an outwardly extending edge plate 33. The edge plate 33 is fixedly connected to the shoulder 15. The lower end surface of the edge plate 33 is fitted with the upper end surface of the shoulder 15 and fixedly connected by screws. A gap is provided between the outer wall of the inner cylinder 3 and the inner wall of the outer cylinder 1. The side wall of the inner cylinder 3 is provided with a plurality of liquid outlet holes 34. The plurality of liquid outlet holes 34 are annularly distributed on the side wall of the inner cylinder 3. The liquid outlet holes 34 connect the inner wall and the outer wall of the inner cylinder 3. The height of the liquid outlet holes 34 determines the height of the internal solution of the inner cylinder 3. After the silk fibroin is dissolved in the reaction, the excess solution will flow out of the inner cylinder 3 through the liquid outlet holes 34 due to the continuous addition of reagents. A part of the floating matter in the solution flows out with the solution through the liquid outlet holes 34, and a part is filtered and retained in the inner cylinder 3.

[0025] The outer cylinder 1 is provided with a liquid collecting plate 13, and the liquid collecting plate 13 is in the shape of a funnel with a diameter gradually decreasing from top to bottom. A filter bucket 14 is installed inside the outer cylinder 1. The funnel-shaped liquid collecting plate 13 can concentrate the solution flowing out of the inner cylinder 3 at the center of the liquid collecting plate 13. The filter bucket 14 is located below the inner cylinder 3. The filter bucket 14 is installed at the center of the liquid collecting plate 13. The filter bucket 14 can filter the floating objects flowing out with the solution. The outer cylinder 1 is provided with a liquid outlet 12, and the liquid outlet 12 is located at the bottom of the outer cylinder 1. The filtered solution flows out through the liquid outlet 12. The filter bucket 14 plays a role of secondary filtration. When all the materials to be reacted are placed in the inner cylinder 3 until the reaction is completed, part of the solution will still remain in the inner cylinder 3. At this time, the inner cylinder 3 must be taken out and the remaining solution in the inner cylinder 3 must be poured into the outer cylinder 1 and filtered through the filter bucket 14.

[0026] An upwardly protruding boss 31 is provided at the bottom of the inner tube 3. An annular groove is formed between the boss 31 and the inner wall of the inner tube 3. The bottom of the groove accommodates impurities that will not float up. The boss 31 can also prevent the silk from accumulating in the center.

[0027] The outer cover 2 is provided with a stirring device 4, which includes a transmission rod 42 and a motor 41. The motor 41 is fixedly installed at the upper end of the outer cover 2, and the motor 41 is fixedly connected to the transmission rod 42. The transmission rod 42 can drive the stirring member 32 to rotate, so as to stir the silk in the solution and accelerate the reaction of the silk fibroin. The upper end surface of the boss 31 is rotatably provided with the stirring member 32, and the stirring member 32 includes a rotating ring 322 and a stirring rod 321. The upper end of the stirring rod 321 is lower than the liquid outlet 34, so as to drive the silk fibroin below the liquid surface of the solution to rotate. The stirring rod 321 is fixedly installed on the outer side of the rotating ring 322. The rotating ring 322 is installed on the upper end surface of the boss 31 through the bearing 35. The inner wall of the rotating ring 322 is provided with an internal gear 3221. The upper end surface of the boss 31 is rotatably installed with a transmission gear 36. The transmission gear 36 is located inside the rotating ring 322. The transmission gear 36 is meshed with the internal gear 3221. The lower end of the transmission rod 42 is provided with a gear rod 423. The gear rod 423 is meshed with the transmission gear 36. The gear rod 423 is concentrically arranged with the rotating ring 322. The motor 41 drives the gear rod 423 to rotate, and drives the rotating ring 322 to rotate through the transmission gear 36 so that the rotation directions of the stirring member 32 and the transmission rod 42 are opposite.

[0028] The transmission rod 42 is provided with a plurality of rotary blades 421, and the plurality of rotary blades 421 are distributed in a ring shape. A gap is provided between the rotary blades 421 and the inner wall of the inner tube 3 for the solution to pass through. The gap cannot be too large to ensure that the silk material will not be stuck between the rotary blades 421 and the inner wall of the inner tube 3. A gap 422 is formed between two adjacent rotary blades 421, and the silk material can enter the lower part of the rotary blade 421 through the gap 422. One side of the rotary blade 421 is inclined upward, and the lowermost end of the rotary blade 421 is flush with the lowermost end of the liquid outlet 34 at the lowermost end. The inclined rotary blade 421 can press the silk material floating on the liquid surface into below the liquid surface, so that the silk material is quickly soaked by the solution and can be driven by the stirring rod 321 to stir and accelerate the reaction.
