Abstract
Description
Technical Field
[0001] This utility model relates to the field of papermaking technology, specifically to a titanium dioxide dispersion device for papermaking. Background Technology
[0002] Titanium dioxide is an indispensable white pigment and functional filler in the papermaking industry. In the papermaking process, titanium dioxide needs to be mixed with plant fiber raw materials and reinforcing chemical raw materials. Its core value lies in improving paper quality through optical performance optimization, and at the same time, it helps to improve physical properties in specific scenarios. By dispersing and contacting titanium dioxide with plant fiber raw materials and reinforcing chemical raw materials, it can avoid quality problems such as color spots in the produced decorative base paper.
[0003] A search revealed that patent application number 202022241053.6 discloses a titanium dioxide and powder progressive dispersion device, comprising a dispersion disc, a dispersion cone, and a rotating shaft. The dispersion disc and the dispersion cone are stacked and coaxially mounted. The dispersion disc is positioned below the dispersion cone, and the circular plane of the dispersion cone is in contact with the upper surface of the dispersion disc. The rotating shaft is installed through the axis of the dispersion disc and the dispersion cone. The upper and lower ends of the rotating shaft are respectively inserted into a cylindrical housing. The dispersion disc divides the housing into a dispersion chamber and a stirring chamber. The top of the housing is provided with two feed inlets for titanium dioxide and powder to enter the dispersion cone.
[0004] Although this titanium dioxide and powder progressive dispersion device, through structural adjustments, employs a two-stage dispersion method with a cone and a dispersion plate, utilizing the friction between solids and the centrifugal force generated by the rotation of the dispersion mechanism to ensure thorough mixing of titanium dioxide and powder, followed by agitation to complete the mixing, this device only allows titanium dioxide to pass through the dispersion nozzle and come into contact with the outer ring of the raw material for mixing. This single-path contact mode makes it difficult for titanium dioxide to penetrate into the central region of the raw material, easily leading to uneven distribution of titanium dioxide and resulting in localized areas of excessively high or low concentrations. This not only causes quality problems such as differences in whiteness and spots in the finished paper, but also reduces the efficiency of titanium dioxide utilization and increases production costs.
[0005] Therefore, we propose a titanium dioxide dispersion device for papermaking. Utility Model Content
[0006] In view of the shortcomings of the existing technology, this utility model provides a titanium dioxide dispersion device for papermaking, which solves the problem that the existing device can only make titanium dioxide pass through the dispersion nozzle and contact the outer ring of the raw material, but cannot make titanium dioxide contact the middle of the raw material, resulting in poor dispersion effect of titanium dioxide.
[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a titanium dioxide dispersion device for papermaking, comprising a mixing tank, a discharge pipe fixedly connected to the side wall at the bottom of the mixing tank, a solenoid valve installed on the discharge pipe, and a raw material addition pipe fixedly connected to the side wall of the mixing tank;
[0008] A feeding assembly is provided on the left side of the top surface of the mixing tank, and a dispersing assembly is provided inside the mixing tank;
[0009] The dispersing assembly includes a motor fixedly installed in the middle of the top surface of the mixing tank. The output end of the motor passes through the top surface of the mixing tank and is connected to a shaft via a coupling. The bottom end of the shaft is rotatably installed on the bottom surface inside the mixing tank via a bearing ring. A fixing plate is rotatably installed on the outer surface of the shaft via the bearing ring. The fixing plate is fixedly fitted onto the inner wall of the mixing tank. A turntable is fixedly fitted onto the outer surface of the shaft on the bottom surface of the fixing plate. The top surface of the turntable is in contact with the bottom surface of the fixing plate. The top surfaces of the fixing plate and the turntable are respectively provided with a radially arranged first discharge hole and a second discharge hole. A stirring component is arranged in a ring array at the bottom of the shaft.
[0010] Preferably, the turntable is rotatably mounted on the inner wall of the mixing tank via a bearing ring. Above the fixed disc, there is a ring-shaped array of stirring rods, the bottom surface of which contacts the top surface of the fixed disc. The raw material addition tube is located below the turntable. The stirring rods can agitate the titanium dioxide powder accumulated on the top surface of the fixed disc, so that the titanium dioxide powder is evenly dispersed on the top surface of the fixed disc.
[0011] Preferably, a connecting ring is fixedly fitted at the top end of the shaft, and the agitator is fixedly installed on the arc surface of the connecting ring, wherein the connecting ring facilitates the installation of the agitator.
[0012] Preferably, the stirring component includes a U-shaped rod and a crossbar. The crossbar is fixedly installed in the middle of the inner wall of the U-shaped rod. Both ends of the U-shaped rod and the end of the crossbar away from the middle of the U-shaped rod are fixedly installed on the outer surface of the bottom end of the shaft. The stirring component facilitates the stirring of the raw materials and titanium dioxide inside the mixing tank, so that the titanium dioxide and raw materials are fully mixed.
[0013] Preferably, the feeding assembly includes a feeding hopper, a connecting pipe, a V-shaped plate, and a discharge hole. The feeding hopper is fixedly installed on the top surface of the mixing tank. The bottom end of the feeding hopper is fixedly connected to the connecting pipe through the top surface of the mixing tank. The bottom end of the connecting pipe is provided with a hollow V-shaped plate. Titanium dioxide is added to the inside of the connecting pipe through the feeding hopper and then enters the inside of the V-shaped plate.
[0014] Preferably, the bottom end of the connecting pipe is fixedly installed in the middle of the top surface of the V-shaped plate and communicates with its interior. The bottom surface of the V-shaped plate has evenly distributed discharge holes. The projected length of the V-shaped plate is the same as the radius of the fixed plate. The titanium dioxide that enters the interior of the V-shaped plate is discharged through the discharge holes and finally falls onto the top surface of the fixed plate.
[0015] This utility model provides a titanium dioxide dispersion device for papermaking. It has the following beneficial effects:
[0016] 1. This titanium dioxide dispersion equipment for papermaking uses a motor to drive the shaft, fixed plate, turntable, stirring component, and stirring rod to rotate. The stirring rod can evenly disperse the titanium dioxide accumulated on the top surface of the fixed plate. When the first and second discharge holes on the fixed plate and turntable overlap, the titanium dioxide accumulated above the fixed plate will fall through the first and second discharge holes to the bottom of the mixing tank and contact the raw material, thus achieving the purpose of evenly dispersing the titanium dioxide on the top of the raw material. The stirring component stirs the raw material and titanium dioxide inside the mixing tank, making the raw material and titanium dioxide evenly mixed. This solves the problem that existing devices can only make titanium dioxide contact the outer ring of the raw material through the dispersing nozzle, but cannot make titanium dioxide contact the middle of the raw material, resulting in poor dispersion effect of titanium dioxide.
[0017] 2. This titanium dioxide dispersion equipment for papermaking, through the setting of a feed hopper, connecting pipe, V-shaped plate and discharge hole, allows titanium dioxide to enter the interior of the connecting pipe and V-shaped plate through the feed hopper, and finally be discharged to the top surface of the fixed plate through the discharge hole. This can make the titanium dioxide evenly dispersed on the top surface of the fixed plate, which is beneficial to improving the dispersion effect of titanium dioxide. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1:
[0026] like Figure 1-5As shown: The system includes a mixing tank 1. A discharge pipe 11 is fixedly connected to the side wall at the bottom of the mixing tank 1. A solenoid valve 12 is installed on the discharge pipe 11. A raw material addition pipe is fixedly connected to the side wall of the mixing tank 1. A feeding assembly 2 is located on the left side of the top surface of the mixing tank 1. A dispersing assembly 3 is located inside the mixing tank 1. The dispersing assembly 3 includes a motor 31 fixedly installed in the middle of the top surface of the mixing tank 1. The output end of the motor 31 passes through the top surface of the mixing tank 1 and is connected to a shaft 32 via a coupling. The bottom end of the shaft 32 is rotatably mounted on the bottom surface inside the mixing tank 1 via a bearing ring. The outer surface of the shaft 32... A fixed disk 33 is rotatably mounted via a bearing ring and is fixedly fitted onto the inner wall of the mixing tank 1. A turntable 34, fixedly fitted onto the outer surface of a shaft 32, is located on the bottom surface of the fixed disk 33. The top surface of the turntable 34 contacts the bottom surface of the fixed disk 33. The top surfaces of the fixed disk 33 and the turntable 34 are respectively provided with radially arranged first discharge holes 331 and second discharge holes 341. A stirring component 35 arranged in a circular array is located at the bottom of the shaft 32. The turntable 34 is rotatably fitted onto the inner wall of the mixing tank 1 via a bearing ring. An agitator arranged in a circular array is located above the fixed disk 33. The bottom surface of the stirring rod 36 contacts the top surface of the fixed plate 33. The raw material addition tube is located below the turntable 34. A connecting ring 37 is fixedly fitted to the top of the shaft 32. The stirring rod 36 is fixedly installed on the arc surface of the connecting ring 37. The stirring component 35 includes a U-shaped rod 351 and a crossbar 352. The crossbar 352 is fixedly installed in the middle of the inner wall of the U-shaped rod 351. Both ends of the U-shaped rod 351 and the end of the crossbar 352 away from the middle of the U-shaped rod 351 are fixedly installed on the outer surface of the bottom end of the shaft 32. The shaft 32, fixed plate 33, turntable 34, and stirring component are driven by the motor 31. The stirring rod 36 rotates, and the stirring rod 36 can make the titanium dioxide powder piled on the top surface of the fixed plate 33 evenly dispersed on the top surface of the fixed plate 33. When the first discharge hole 331 and the second discharge hole 341 on the fixed plate 33 and the turntable 34 overlap, the titanium dioxide powder piled on the top of the fixed plate 33 will fall through the first discharge hole 331 and the second discharge hole 341 to the bottom of the mixing tank 1 and contact the raw materials, thus achieving the purpose of making the titanium dioxide powder evenly dispersed on the top of the raw materials. The stirring rod 35 stirs the raw materials and titanium dioxide powder inside the mixing tank 1, so that the raw materials and titanium dioxide powder are mixed evenly.
[0027] Example 2:
[0028] like Figure 1 , 2As shown in Figure 5: The feeding assembly 2 includes a feeding hopper 21, a connecting pipe 22, a V-shaped plate 23, and a discharge hole 24. The feeding hopper 21 is fixedly installed on the top surface of the mixing tank 1. The bottom end of the feeding hopper 21 passes through the top surface of the mixing tank 1 and is fixedly connected to the connecting pipe 22. The bottom end of the connecting pipe 22 is provided with a hollow V-shaped plate 23. The bottom end of the connecting pipe 22 is fixedly installed in the middle of the top surface of the V-shaped plate 23 and communicates with its interior. The bottom surface of the V-shaped plate 23 has evenly distributed discharge holes 24. The projected length of the V-shaped plate 23 is the same as the radius of the fixed disk 33. Through the arrangement of the feeding hopper 21, the connecting pipe 22, the V-shaped plate 23, and the discharge hole 24, titanium dioxide enters the interior of the connecting pipe 22 and the V-shaped plate 23 through the feeding hopper 21, and is finally discharged onto the top surface of the fixed disk 33 through the discharge hole 24. This allows the titanium dioxide to be evenly dispersed on the top surface of the fixed disk 33, which is beneficial to improving the dispersion effect of titanium dioxide.
[0029] The working principle and usage process of this utility model: In use, the raw materials are transported into the mixing tank 1 through the raw material addition pipe. Then, titanium dioxide is added to the connecting pipe 22 through the feed hopper 21. The titanium dioxide then enters the V-shaped plate 23 through the connecting pipe 22 and is discharged onto the top surface of the fixed plate 33 through the discharge hole 24. Simultaneously, the motor 31 is started, driving the shaft 32, the fixed plate 33, and the turntable 34 to rotate. During this process, when the first discharge hole 331 on the fixed plate 33 and the turntable 34... When the second discharge hole 341 overlaps, the titanium dioxide accumulated above the fixed plate 33 will fall through the first discharge hole 331 and the second discharge hole 341 to the bottom of the mixing tank 1 and come into contact with the raw materials. The shaft 32 can drive the stirring component 35, the connecting ring 37 and the stirring rod 36 to rotate synchronously. Then the stirring rod 36 can make the titanium dioxide accumulated on the top surface of the fixed plate 33 evenly disperse on the top surface of the fixed plate 33. At the same time, the stirring component 35 stirs the raw materials and titanium dioxide inside the mixing tank 1, so that the raw materials and titanium dioxide are mixed evenly.
