Description

Technical Field

[0001] The utility model relates to the technical field of fluorescent whitening agent production, and more specifically, to a raw material separation device for fluorescent whitening agent. Background Art

[0002] Fluorescent whitening agent is a kind of fluorescent dye, or white dye, which is also a general term for a class of compounds. Its characteristic is that it can stimulate incident light to produce fluorescence, so that the dyed substance obtains a glittering effect similar to fluorite, making the substance very white to the naked eye.

Obviously, the specific implementation mode described is only a part of the implementation mode of the utility model, rather than all styles.

[0033] Example:

[0034] The following is combined with Figure 1-6 The utility model is described in further detail.

[0035] See also Figure 1-6 The utility model provides a technical solution: a raw material separation device for fluorescent whitening agent, comprising a box body 1, a movable processing box 6 is arranged in the box body 1, both sides of the processing box 6 are open to form a channel connected to the outside, and an arc-shaped sieve plate 7 is arranged at the bottom of the processing box 6;

[0036] A blower head 19 capable of rotating to blow air is disposed above the processing box 6, and shielding components 16 are disposed on both sides of the inner wall of the box body 1, and the two shielding components 16 are respectively matched with the two open sides of the processing box 6;

[0037] The shielding assembly 16 includes a support plate 161 , which is fixedly connected to one side of the inner wall of the box body 1 , and the support plate 161 shields the open side of the processing box 6 .

[0038] Specifically, a limiting groove 162 is provided at the bottom of the support plate 161, a supporting rod 163 is fixedly connected in the limiting groove 162, a baffle 164 is rotatably connected to the outer surface of the supporting rod 163, springs (not shown in the figure) are arranged between the two baffles 164 and both sides of the inner wall of the box body 1, so that the baffles 164 can shield both sides of the processing box 6 when the processing box 6 is in the screening state, and protective frames 17 are fixedly connected to both sides of the box body 1, and the two baffles 164 are respectively matched with the two protective frames 17, and the side wall of the box body 1 is rotatably connected to the first rotating shaft 3, Two rotating plates 4 are fixedly connected to the outer surface of the first rotating shaft 3, and push rods 5 are rotatably connected to both sides of the two rotating plates 4. The bottom ends of the four push rods 5 are rotatably connected to the top of the processing box 6. A ventilation pipe 18 is provided at the bottom of the first rotating shaft 3, and the ventilation pipe 18 is located between the two rotating plates 4. The blower head 19 is fixedly connected to the bottom of the ventilation pipe 18 and is connected to the ventilation pipe 18. An air pump 21 is fixedly connected to one side of the box body 1, and a delivery pipe 20 is fixedly connected to the output end of the air pump 21. The other end of the delivery pipe 20 passes through the box body 1 and is connected to the ventilation pipe 18.

[0039] By adopting the above technical solution, the first rotating shaft 3, the rotating plate 4 and the pushing rod 5 can conveniently drive the processing box 6 to swing back and forth, so as to perform screening operations on the raw materials put in. The processing box 6 can be blown by the blowing head 19, the ventilation pipe 18 and the air pump 21, and the raw material residue can be released by cooperating with the shielding component 16, and the arc-shaped screen plate 7 can be blown and cleaned.

[0040] Specifically, a feed barrel 9 is fixedly connected to the top of the box body 1, the bottom of the feed barrel 9 cooperates with the inlet of the processing box 6, a feed hopper 10 is arranged on the top of the feed barrel 9, and the side wall of the feed barrel 9 is rotatably connected to the second rotating shaft 11, and the outer surface of the second rotating shaft 11 is fixedly connected to a crushing blade 12, and the crushing blade 12 is located in the feed barrel 9, the outer surface of the first rotating shaft 3 is fixedly connected to the first gear 8, and the outer surface of the second rotating shaft 11 is fixedly connected to the second gear 13, the first gear 8 and the second gear 13 are both located on one side of the box body 1, and a servo motor 14 is fixedly connected to one side of the box body 1, and the output shaft of the servo motor 14 is fixedly connected to a driving gear 15, and the driving gear 15 is respectively meshed with the first gear 8 and the second gear 13.

[0041] By adopting the above technical solution, the raw materials before screening are crushed through the feed barrel 9, the second rotating shaft 11 and the crushing blade 12 to avoid the formation of lumped raw materials, which will affect the screening efficiency and cause the arc screen plate 7 to be blocked. The first rotating shaft 3 and the second rotating shaft 11 are driven to rotate through the first gear 8, the second gear 13, the servo motor 14 and the driving gear 15, so that crushing and screening can work synchronously.

[0042] Specifically, the distance between the position of any point on the two shielding components 16 and the position of any point on both sides of the processing box 6 is greater than zero, the arc-shaped screen plate 7 is a shape that gradually decreases from the middle height to the two sides, the bottom of the box body 1 is fixedly connected to the base 2, the bottom of the box body 1 is provided with a discharge port 22, and a storage box 23 is placed on the top of the base 2, and the discharge port 22 cooperates with the storage box 23.

[0043] By adopting the above technical solution, the distance between the shielding component 16 and any point on both sides of the processing box 6 is greater than zero, which means that there is a gap between the shielding component 16 and the processing box 6 on both sides, so as to avoid the shielding component 16 affecting the processing box 6 to achieve shaking screening. The arc-shaped screen plate 7 with a shape that gradually decreases from the middle height to both sides is convenient for releasing the raw material residue after screening. The storage box 23 is convenient for storing the screened raw materials, which is convenient for the staff to handle uniformly.

[0044] The working principle of the utility model is as follows: when in use, the staff puts the fluorescent whitening agent raw materials that need to be screened into the feed hopper 10, and supplies power through an external power supply. The servo motor 14 works, and the output shaft of the servo motor 14 starts to rotate forward. After rotating to a set angle, the output shaft starts to reverse and rotates to another set angle, and repeats this process, thereby driving the driving gear 15 to rotate forward and reverse, and meshing and driving the first gear 8 and the second gear 13 to start rotating forward and reverse, driving the crushing blade 12 located in the feed barrel 9 to rotate forward and reverse, and crushing the raw materials put in, avoiding the formation of agglomerated raw materials, which affects the screening efficiency and easily causes the arc sieve plate 7 to be blocked.

[0045] The crushed raw materials fall into the processing box 6, and the first gear 8 rotates forward and reversely, driving the two rotating plates 4 on the first rotating shaft 3 to rotate forward and reversely, driving the pushing rods 5 on both sides of the rotating plates 4 to start moving, pulling the processing box 6 through the pushing rods 5 on one side, and pushing the processing box 6 on the other side, so that the processing box 6 tilts to one side, and then the first rotating shaft 3 is reversed, driving the rotating plate 4 to reverse, driving the pushing rods 5 on one side to push the processing box 6, and the pushing rods 5 on the other side pull the processing box 6, so that the processing box 6 shakes back and forth, and the raw materials put in are screened, and the screened raw materials fall into the storage box 23 through the discharge port 22, which is convenient for the staff to uniformly process and use.

[0046] After the raw materials are screened, raw material residues remain in the processing box 6. The air pump 21 works to inflate the conveying pipe 20, enter the ventilation pipe 18 through the conveying pipe 20, and are blown out by the blowing head 19 below the ventilation pipe 18. The air passes through the inlet of the processing box 6 and enters the processing box 6 to blow the arc sieve plate 7. The raw material residues accumulated on the arc sieve plate 7 move to the two sides of the open state of the processing box 6. Since the arc sieve plate 7 is high in the middle and low on both sides, the raw material residues will generate thrust on the baffles 164 on both sides, so that the baffle 164 on the shielding assembly 16 rotates on the support rod 163, and the baffle 164 rotates into the protective frame 17. The baffle 164 is limited by the protective frame 17, so that discharge ports are generated on both sides of the processing box 6, so that the raw material residues left in the processing box 6 after screening are discharged on both sides of the processing box 6, and the blowing will clean the residues hanging on the arc sieve plate 7, so as to facilitate subsequent screening operations.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
