It can produce fluorescence when incident light is excited, making the dyed object sparkle and whiten the material to the naked eye, thus achieving a whitening effect. In the production process of fluorescent agent, stirring is a very important step. At present, fixed one-way stirring is generally used, which may cause the material to flocculate and settle at the bottom edge.

[0003] Chinese patent application No. 202011236291.6 discloses a mixing device for a fluorescent whitening agent composition for papermaking, which is provided with a stirring rod, a hollow blade, a stirring paddle and a dispersing sheet.

The pulley 2 4 is provided with a transmission shaft 6. The transmission shaft 6 runs through the top of the housing 1, and the transmission group is provided with a bearing, which is rotatably connected to the housing 1 through the bearing; a belt 5 is provided between the pulley 1 3 and the pulley 2 4, which is connected through the belt 5. The other end of the transmission shaft 6 is fixedly connected to a connecting rod 7, and the other end of the connecting rod 7 is rotatably connected to a rack; the top of the housing 1 is rotatably connected to an outer rotating tube 11, and the other end of the outer rotating tube 11 is connected to a rotating disk 10; an inner rotating tube 13 is provided inside the outer rotating tube 11, and the top of the inner rotating tube 13 is rotatably connected to the wall of the housing 1, and the other end of the inner rotating tube 13 is connected to a circular gear 12, which is rotatably connected to the rotating disk 10. One side of the rotating disk 10 is connected to a box body 9, and a rack is provided inside the box body 9, and a side of the rack close to the circular gear 12 is provided with teeth, and the rack is meshed and connected with the circular gear 12 through the provided teeth.

[0033] The rack and the box body 9 are set to slide in a gap. A slide groove 81 is provided on the side of the rack away from the gear. A slider 82 is provided in the slide groove 81. The slider 82 is ellipsoidal and is slidably connected to the slide groove 81. The slider 82 is connected to a slide rod 83, and the other end of the slide rod 83 is connected to the inner wall of the box body 9. A transmission tube 14 is connected to the side of the circular gear 12 away from the outer rotating tube 11, and the transmission tube 14 is rotatably connected to the rotating disk 10; the other end of the transmission tube 14 is connected to an upper bevel gear 18, and the upper bevel gear 18 is meshedly connected to a transmission bevel gear 19, and the other side of the transmission bevel gear 19 is meshedly connected to a lower bevel gear 20; a fixed rod 15 is provided in the transmission tube, and the fixed rod 15 passes through the circular gear 12 and the inner rotating tube 13, and is rotatably arranged with a gap between the circular gear 12 and the inner rotating tube 13; the upper top of the fixed rod 15 is fixedly connected to the inner wall of the shell 1, and the lower end of the fixed rod 15 passes through the upper bevel gear 18, and is rotatably connected with the upper bevel gear 18, and two transmission bevel gears 19 are symmetrically arranged, and the two transmission bevel gears 19 are rotatably connected to the fixed rod 15 through the provided bearings; fixed blocks 16 are symmetrically connected to the transmission tube 14, and each fixed block 16 is connected to an outer stirring rod 17. The lower bevel gear 20 is connected to an inner rotating frame 21 . The inner rotating frame 21 is in a “U”-shaped structure. The inner rotating frame 21 is arranged on the inner side of the outer stirring rod 17 .

[0034] Specifically, the fluorescent whitening agent material is added into the shell 1 through the feed pipe 30, the starting motor 2 drives the pulley 1 3 to rotate through the belt 5, the pulley 2 4 drives the connecting rod 7 to rotate periodically, and the connecting rod 7 drives the rack 8 to reciprocate in the box body 9 during the periodic rotation. When the rack 8 moves, the rack 8 is meshed and connected with the circular gear 12, driving the circular gear 12 to rotate; it should be understood that when the rack 8 drives the circular gear 12 to rotate, the rack 8 slides relatively in the box body 9, and the rack 8 slides in the slide groove 81 through the ellipsoidal slider 82. Since the motion trajectory of the rack 8 is an arc, when the slider 82 slides in the slide groove 81, when the slider 82 is hindered by the slide groove 81, the friction between the two increases. Since the slider 82 is subjected to the resistance, it will drive the box body 9 to rotate at a small angle. The box body 9 is connected to the rotating disk 10, and the rotating disk 10 passes through the bearing at the top of the shell 1. The gear 12 is driven by the gear 12 to rotate in a direction opposite to that of the upper bevel gear 18. The gear 12 drives the outer stirring rod 17 to rotate, and the lower bevel gear 20 drives the inner rotating frame 21 to rotate. Therefore, the rotation direction of the outer stirring rod 17 is opposite to that of the inner rotating frame 21, and the gear 12 is driven to rotate alternately clockwise and counterclockwise through the reciprocating movement of the rack 8, thereby realizing the alternating directional stirring of the outer stirring rod 17 and the inner stirring frame, further improving the stirring uniformity and preventing the unidirectional rotation from forming material flocculation or deposition at the bottom of the shell 1.

[0035] Embodiment 2:

[0036] Based on Example 1, refer to Figure 5 The outer stirring rod 17 is connected to an elastic member 28 on one side close to the inner wall of the shell 1, and the other end of the elastic member 28 is connected to a scraper 26, and a flexible layer 27 is provided on the other side of the scraper 26. The scraper 26 is vertically arranged inside the shell 1 and can form a friction sliding connection with the inner wall of the shell 1. There are two outer stirring rods 17, each of which is provided with two outer stirring blades 23, and four inner stirring blades 22 are provided on the "U"-shaped inner rotating frame 21. The elastic member 28 is a spring or an elastic sheet, and the elastic member 28 is made of plastic or metal; the flexible layer 27 is made of rubber or other elastic plastic parts.

[0037] Specifically, when the outer rotating rod rotates, a channel 25 is provided inside the outer stirring rod 17 to cooperate with the guide tube 24. When the stirring rod rotates, the gas in the guide tube 24 is discharged by centrifugal force, forming a negative pressure. The liquid material at the bottom of the shell 1 enters the channel 25 under the pressure and moves upward, and is sprayed out by the guide tube 24, which not only prevents the material at the bottom of the shell 1 from depositing, but also can pump the material at the bottom to the top for stirring, thereby improving the mixing effect; the scraper 26 is provided with an elastic member 28 elastically connected to the outer stirring rod 17. When rotating, the scraper 2 6 is subjected to the centrifugal effect, and the elastic member 28 is stretched by the centrifugal effect until the friction between the rubber flexible layer 27 of the scraper 26 and the inner wall of the shell 1 is released. When the scraper 26 rotates, the material adhered to the inside of the shell 1 is scraped off through the flexible layer 27, so as to prevent the liquid material from being deposited on the inner wall of the shell 1 during the long-term stirring process, which is difficult to remove. When the rotation stops, the scraper 26 is automatically reset by the restoring effect of the elastic member 28 and is separated from the inner wall of the shell 1, so as to prevent the flexible layer 27 from adhering to the inner wall of the shell 1.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
