Description

Technical Field

[0001] The utility model relates to the technical field of fluorescent whitening agent production, in particular to a crystal film separation device used for producing fluorescent whitening agent. Background Art

[0002] Fluorescent whitening agent is a 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, making the dyed substance obtain a glittering effect similar to fluorite, making the substance appear very white to the naked eye;

[0003] During the production and processing of existing fluorescent brighteners, crystallization film precipitation equipment is required to react the materials and precipitate crystals. In actual use, the equipment is often stirred and mixed with a stirring rod under heating conditions to enhance the reaction effect. However, during the reaction, stirring with the stirring rod alone can cause the materials to sink, resulting in insufficient vertical mixing of the materials, which in turn affects the crystallization effect. Therefore, we propose a crystallization film precipitation equipment for the production of fluorescent brighteners. Utility Model Content

[0006] A first gear is fixedly mounted on the upper side of the outer wall of the hollow shaft, a second gear is meshed with the outer wall of the first gear, the second gear is fixed to the outer end of the transmission shaft of the servo motor, the servo motor is fixed to the top of the reaction cylinder, and the two sides of the tail end of the hollow shaft are respectively fixedly connected with air distribution pipes, and a plurality of evenly distributed first air outlet holes are provided on the upper surface of the air distribution pipe, and the top of the hollow shaft is connected to the air supply pipe through a rotary joint.

[0007] By adopting the above technical solution, the material is first introduced into the inner cavity of the reaction cylinder and heated by the electric heating plate, and then the servo motor drives the second gear to rotate, thereby driving the first gear to rotate, so that the hollow shaft rotates, driving the stirring rod to stir the material for reaction. At the same time, during the reaction process, the air supply pipe introduces gas into the hollow shaft, and then the gas enters the inner cavity of the air distribution pipe, and then blows upward along the first air outlet, so that the material not only realizes the horizontal stirring movement, but also the gas from the bottom to the top drives the material to have a longitudinal movement trajectory, so that the material is stirred more fully, thereby improving the effect of crystal film precipitation.

[0008] As a preferred embodiment of the present invention, the stirring rod is a hollow structure, and a side wall of the stirring rod is provided with a plurality of evenly distributed second air outlet holes.

[0009] By adopting the above technical solution, the second air outlet is set up so that the gas can be discharged along the second air outlet during the stirring process, and the stirring rotation direction is opposite to the air outlet direction, so that the stirred material can be pushed in the opposite direction to move, thereby increasing the collision between the materials and improving the stirring and mixing effect.

[0010] As a preferred embodiment of the present invention, the second air outlet holes are arranged obliquely, wherein the second air outlet holes on two groups of the stirring rods are arranged obliquely outward, and the second air outlet holes on the other two groups of the stirring rods are arranged obliquely inward.

[0011] By adopting the above technical solution, the second air outlet is arranged obliquely so that when the gas acts on the material, it can push the material outward and inward alternately, thereby further improving the material mixing effect and further improving the stirring reaction effect.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] The technical solution of the present application is a crystal film precipitation device for producing fluorescent whitening agents. During the stirring process, the gas distribution pipe can use the first gas outlet to guide the gas, and then blow it upward along the first gas outlet. Therefore, the material is not only stirred horizontally, but also driven by the gas from bottom to top to move the material in a longitudinal direction, thereby making the material more fully stirred, thereby improving the effect of crystal film precipitation.

[0017] During the stirring process, the gas can be discharged through the second gas outlet, and the stirring rotation direction is opposite to the gas outlet direction, so that the stirred material can be pushed in the opposite direction to increase the collision between the materials, thereby improving the stirring and mixing effect;

[0018] The second air outlet hole is arranged obliquely so that when the gas acts on the material, it can push the material outward and inward alternately, thereby further improving the material mixing effect and further improving the stirring reaction effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] See also Figure 1-4 The utility model provides a technical solution: a crystal film precipitation device for producing fluorescent whitening agents, comprising a reaction cylinder 1, a hollow shaft 11 is movably connected to the top of the reaction cylinder 1, a plurality of uniformly distributed stirring rods 18 are fixed to the outer wall of the hollow shaft 11, the stirring rods 18 are located in the reaction cylinder 1, and a plurality of uniformly distributed electric heating plates 2 are fixed to the inner wall of the reaction cylinder 1;

[0030] A first gear 12 is fixedly mounted on the upper side of the outer wall of the hollow shaft 11, and a second gear 13 is meshed with the outer wall of the first gear 12. The second gear 13 is fixed to the outer end of the transmission shaft of the servo motor 14, and the servo motor 14 is fixed to the top of the reaction cylinder 1. The two sides of the tail end of the hollow shaft 11 are fixedly connected to the gas distribution pipe 3. The upper surface of the gas distribution pipe 3 is provided with a plurality of uniformly distributed first air outlet holes 31. The top of the hollow shaft 11 is connected to the air supply pipe 4 through a rotary joint 41.

[0031] In actual use, the material is first introduced into the inner cavity of the reaction cylinder 1 and heated by the electric heating plate 2. Then the servo motor 14 drives the second gear 13 to rotate, thereby driving the first gear 12 to rotate, so that the hollow shaft 11 rotates, driving the stirring rod 18 to stir the material for reaction. At the same time, during the reaction process, the air supply pipe 4 introduces gas into the hollow shaft 11, and then the gas enters the inner cavity of the air distribution pipe 3, and then blows upward along the first air outlet 31, so that the material not only realizes the horizontal stirring movement, but also the gas from the bottom to the top drives the material to have a longitudinal movement trajectory, so that the material is stirred more fully, thereby improving the effect of crystal membrane.

[0032] Furthermore, a feed pipe 17 is fixedly connected to one side of the top of the reaction cylinder 1 , and a sealing cover is detachably fixed to the outer end of the feed pipe 17 , so that the sealing cover can be opened to facilitate the introduction of materials into the reaction cylinder 1 .

[0033] Furthermore, an electromagnetic pressure relief valve 16 is fixedly connected to the upper side of one side wall of the reaction cylinder 1. The electromagnetic pressure relief valve 16 can relieve the pressure inside the reaction cylinder 1 to avoid danger caused by excessive pressure.

[0034] It is worth mentioning that the tail end of the reaction cylinder 1 is fixedly connected to a discharge valve and the outer end of the discharge valve is fixedly connected to a discharge pipe 15. The crystals can be discharged through the discharge pipe 15, and when the crystals are discharged, the gas supply pipe 4 can be used to introduce gas into the reaction cylinder 1 for pressurization, thereby assisting the discharge and improving the efficiency of the discharge.

[0035] like Figure 1 and 2As shown; the stirring rod 18 is a hollow structure, and a plurality of evenly distributed second air outlet holes 19 are opened on one side wall of the stirring rod 18. The setting of the second air outlet holes 19 allows the gas to be discharged along the second air outlet holes 19 during the stirring process, and makes the stirring rotation direction and the air outlet direction opposite, so that the stirred material can be pushed in the opposite direction to move, thereby increasing the collision between the materials and improving the stirring and mixing effect.

[0036] Furthermore, the second air outlet 19 is arranged at an angle, wherein the second air outlet 19 on two groups of stirring rods 18 are arranged at an angle outward, and the second air outlet 19 on the other two groups of stirring rods 18 are arranged at an angle inward. The inclined second air outlet 19 enables the gas to push the material alternately outward and inward when acting on the material, thereby further improving the material mixing effect and further improving the stirring reaction effect.

[0037] The implementation principle of the crystal membrane equipment for producing fluorescent whitening agents in the present application is as follows: in actual use, the material is first introduced into the inner cavity of the reaction cylinder 1 and heated by the electric heating plate 2, and then the servo motor 14 drives the second gear 13 to rotate, thereby driving the first gear 12 to rotate, so that the hollow shaft 11 rotates, driving the stirring rod 18 to stir the material for reaction, and at the same time, during the reaction process, the air supply pipe 4 introduces gas into the hollow shaft 11, and then the gas enters the inner cavity of the air distribution pipe 3, and then blows upward along the first air outlet 31, so that the material not only realizes the horizontal stirring movement, but also the gas from the bottom to the top drives the material to have a longitudinal movement trajectory, and at the same time, during the stirring process, the gas can be blown along the second air outlet 1 9 is exported, and the stirring rotation direction is opposite to the exhaust direction, so that the stirred material can be pushed in the opposite direction to move, thereby increasing the collision between the materials, thereby improving the stirring and mixing effect, and when the gas exported from the inclined second air outlet 19 acts on the material, it can alternately push the material outward and inward, thereby further improving the material mixing effect, and further improving the stirring reaction effect, thereby making the material stirring more sufficient, thereby improving the effect of crystal membrane formation, and opening the discharge valve when discharging the material, and the crystal can be exported through the discharge pipe 15, and when the crystal is exported, the gas supply pipe 4 can be used to introduce gas into the reaction cylinder 1 for pressurization, thereby assisting the discharge and improving the efficiency of the discharge.
