[0023] For further information, see Figure 3 , Figure 5 and Figure 6The front side of the rotating shaft 251 is fixedly connected with a bevel gear 1 25, and the rotating shaft 251 can limit the transmission mechanism 1 24 and the bevel gear 1 25, and the outer surface of the bevel gear 1 25 is meshedly connected with a bevel gear 26, and the surface of the bevel gear 26 is fixedly connected with a rotating rod 1 27, and the bevel gear 26 can drive the rotating rod 1 27 to rotate, and the inner cavity of the rotating rod 1 27 is slidably connected with a rotating rod 28, and the outer surface of the rotating rod 28 is rotatably connected to the stirring tank 1, and the outer surface of the rotating rod 28 is fixedly connected with a limiting block 1 29, and the outer surface of the limiting block 1 29 is slidably connected to the rotating rod 1 27, and the limiting block 1 29 can make the rotating rod 28 rotate with the rotating rod 1 27, and at the same time does not hinder the up and down movement of the rotating rod 28, and the front side of the vertical part of the L-shaped seat 21 is fixedly connected with a supporting block 210, which is convenient for providing support for the rotating rod 1 27 and the rotating rod 28 to keep it stable, and the outer surface of the rotating rod 28 is fixedly connected with a stirring rod 211.

[0024] For further information, see Figure 5 The shaking assembly 3 includes an eccentric wheel 31 fixedly connected to the outer surface of the rotating shaft 23, the outer surface of the eccentric wheel 31 is rotatably connected to a ring sleeve 32, the lower end of the ring sleeve 32 is fixedly connected to a connecting rod 33, the rotation of the eccentric wheel 31 will drive the ring sleeve 32 and the connecting rod 33 to slightly shake up and down and left and right, the inner surface of the lower end of the connecting rod 33 is rotatably connected to a fixed rod 34, the fixed rod 34 can limit the ring sleeve 32 and the connecting rod 33, so that when it shakes up and down, it drives the two swing seats 36 to swing around the rotating shaft 2 35 as the axis.

[0025] For further information, see Figure 5-6 The front side of the vertical part of the L-shaped seat 21 is fixedly connected with a rotating shaft 25, and the outer surface of the rotating shaft 25 is rotatably connected to two swinging seats 36. The rotating shaft 25 is convenient for limiting the swinging seat 36, so that the swinging seat 36 can only swing with the rotating shaft 25 as the axis. The interior of the two swinging seats 36 is slidably connected with sliding blocks 37, and the outer surface of the rotating rod 28 is fixedly connected with a fixed block 38, and the outer surface of the fixed block 38 is symmetrically fixedly connected with the limiting axis 39. The two sliding blocks 37 are rotatably connected with the two limiting axes 39 at one end away from the swinging seat 36. When the swinging seat 36 drives the sliding block 37 to swing, it can drive the fixed block 38 and the rotating rod 28 as a whole to move slightly up and down, so that the entire stirring rod 211 will also continuously shake up and down when rotating, further breaking the adhesion and agglomeration phenomenon between the materials. The outer surface of the fixed rod 34 is fixedly connected to the two swinging seats 36, and the fixed rod 34 is convenient for connecting the connecting rod 33 with the swinging seat 36, so that the two move together.

[0026] Pour the urokinase raw material and its auxiliary agent into the stirring tank 1 from the opening of the fixed seat 13, start the motor 22 to drive the rotating shaft 23 to rotate, so that the rotating shaft 23 drives the transmission mechanism 24 to rotate, drives the bevel gear 1 25 to mesh with the bevel gear 26, drives the rotating rod 1 27 to rotate, and rotates the rotating rod 28, the limiting block 1 29 and the stirring rod 211 together to stir the urokinase raw material and its auxiliary agent, and the rotating shaft 1 23 will drive the eccentric wheel 31 to rotate while rotating, thereby driving the annular sleeve 32 and the connecting rod 33 to shake up and down and left and right, and further drive the swing seat 36 to swing up and down with the rotating shaft 2 35 as the axis, so that the sliding block 37, the fixed block 38 and the limiting shaft 39 drive the rotating rod 28 and the stirring rod 211 to shake up and down as a whole.

[0027] Therefore, the present scheme achieves the effect of shaking the urokinase raw material and its auxiliary agent while stirring through the cooperation of the stirring component 2 and the shaking component 3, so as to effectively break the adhesion and agglomeration between the materials, promote the dispersion and mixing of the materials, and make the urokinase raw material and its auxiliary agent more evenly distributed in the stirring tank 1. At the same time, the shaking component 3 can also reduce the accumulation of materials on the stirring rod 211 or the inner wall of the stirring tank 1, avoiding the problem of local overheating caused by excessive local materials.

[0028] Embodiment 3: This embodiment is based on Embodiments 1 and 2, and is for achieving the effect of continuous filtration and automatic cleaning of urokinase raw materials and auxiliary agents thereof.

[0029] For details, see Figure 1-3 , Figure 7-10 The filter assembly 4 includes a transmission mechanism 2 41 fixedly connected to the upper end of the rotating rod 1 27. The transmission mechanism 2 41 is composed of a belt and two pulleys, which is the prior art. The lower side of the transmission mechanism 2 41 away from one end of the rotating rod 1 27 is fixedly connected with a bidirectional screw rod 42. The outer surface of the bidirectional screw rod 42 is threadedly connected with a convex frame 43. The rotation of the bidirectional screw rod 42 can drive the convex frame 43 to continuously perform lifting and lowering movements on the surface of the bidirectional screw rod 42.

[0030] For further information, see Figure 2 , Figure 3 , Fig. 9 and Fig.10The outer surface of the rotating rod 28 is fixedly connected with two limit blocks 246, and the outer surface of the limit block 46 is slidably connected with the filter plate 44. The outer surface of the filter plate 44 is provided with a through groove 45, and the outer surface of the filter plate 44 is provided with a limit groove 1 451. The outer surfaces of the two limit blocks 46 are slidably connected with the limit groove 1 451. The limit block 46 can limit the filter plate 44 so that it rotates with the rotating rod 28, and can also be lifted and lowered on the limit block 46, and the position of the limit groove 2452 is always on the same vertical line with the stirring rod 211. The outer surface of the filter plate 44 is provided with a limit groove 2452, so that the filter plate 44 will not be blocked by the stirring rod 211 when it is lifted and lowered.

[0031] Furthermore, one end of the convex frame 43 away from the bidirectional screw rod 42 is rotatably connected to the second limiting groove 452, and the side surface of the convex frame 43 is rotatably connected to the inner surface of the stirring tank 1. The convex frame 43 can drive the filter plate 44 to rise and fall back and forth, allowing the filter plate 44 to repeatedly filter the urokinase raw material and its auxiliary agent to ensure their purity and stability, and the side surface of the convex frame 43 can also be used to clean the inner wall of the stirring tank 1 to avoid residues adhering to the inner wall.

[0032] For further information, see Fig.10 The scraper assembly 5 includes a spring 51 fixedly connected to the top wall of the fixing seat 13, which can provide a buffer space for the rise of the filter plate 44. When the filter plate 44 contacts the collecting box 53, it can still rotate and move upward a certain distance, so that the collecting box 53 can scrape away the impurities filtered out from the surface of the filter plate 44. The bottom end of the spring 51 is fixedly connected to a connecting plate 52, and the internal thread of the connecting plate 52 is connected to a bolt 54. The outer surface of the bolt 54 is threadedly connected to the collecting box 53, which is convenient for replacing and cleaning the collecting box 53. The lower end of the collecting box 53 is slidably connected to the filter plate 44.

[0033] When the rotating rod 1 27 is rotating, it can drive the two transmission mechanisms 2 41 to rotate, and the transmission mechanism 2 41 drives the two-way screw rods 42 on both sides to rotate in the same direction, so that the convex frame 43 drives the filter plate 44 to pass through the stirring rod 211, and continuously rise and fall inside the stirring tank 1. When the upper end of the filter plate 44 contacts the collecting box 53, it continues to rise and rotate. At this time, the upward force will squeeze the spring 51, so that the collecting box 53 and the filter plate 44 are more closely fitted. The collecting box 53 can clean the impurities filtered out on the surface of the filter plate 44 and collect them inside the collecting box 53. Then the filter plate 44 will continue to descend and rise with the convex frame 43, and continuously reciprocate to filter the urokinase raw material and its auxiliary agent. Among them, the collecting box 53 can be separated from the connecting plate 52 by the bolt 54, which is convenient for cleaning and replacing the collecting box 53.

[0034] Therefore, this solution uses the structural coordination between the stirring component 2, the filtering component 4 and the scraper component 5 to enable the filter plate 44 to continuously rise and fall during the stirring process, thereby achieving the effect of real-time capture and separation of large particles of impurities or incompletely dissolved solids in the mixed liquid, thereby ensuring the purity of the mixed liquid, while the scraper component 5 can automatically clean the impurities on the filter plate 44, avoiding the downtime for cleaning caused by blockage of the filter plate 44, thereby improving the continuous operation capability and work efficiency of the equipment.
