Description

Technical Field

[0001] The utility model relates to a high-viscosity polymer mother liquor ultra-gravity quick dissolving and ripening device, belonging to the technical field of high-viscosity polymer quick dispersing and dissolving equipment. Background Art

[0002] When using an ultra-gravity rotating packed bed to quickly disperse and dissolve a high-viscosity polymer, the uniform distribution of the liquid in the high-speed rotating packed bed is very critical, as it directly affects the dynamic balance of the rotating equipment and the dispersion and maturation effect of the polymer. Existing dispersing and dissolving equipment, such as a dispersing and dissolving device disclosed in the utility model patent with the authorization announcement number CN 203971848U, can complete the dispersion work, but during its use, the high-viscosity polymer mother liquor is accelerated through a spiral pipe and then dispersed through the filler, which can meet the use requirements to a certain extent. However, the method of using a spiral pipe to accelerate has the problem of low working efficiency, so it is necessary to develop a new combined liquid distributor to solve the above problems of the existing high-viscosity polymer rapid dispersion method.

DETAILED DESCRIPTION

[0020] The high-viscosity polymer mother liquid ultra-gravity rapid dissolution and ripening device comprises a dispersion tank 1, a sprayer 2, a rotating centrifugal cylinder 5 and a rotating packed bed 6 (see the attached manual). Figure 1 ).

[0021] A discharge pipe 15 is provided at the bottom of the dispersion tank 1 ; during operation, the highly viscous polymer mother liquor that has been separated will eventually be discharged through the discharge pipe 15 .

[0022] The upper part of the dispersion tank 1 is equipped with a sprayer 2 (see the attached manual). Figure 1 The sprayer 2 includes a drainage pipe 7, a material storage ring pipe 8 and a spray tube 10 (see the attached manual). Figure 2 ). Two groups of drainage pipes 7 are symmetrically fixed on the upper end of the storage ring pipe 8; the upper end of the drainage pipe 7 passes through the dispersion tank 1 and is fixed with a connecting flange 9. The dispersion tank 1 is connected to the external feeding device through the connecting flange 9.

[0023] A plurality of spray cylinders 10 are installed at the lower end of the material storage ring tube 8; a rotating shaft 4 is installed inside the material sprayer 2 through a driving motor 3; a rotating centrifugal cylinder 5 is installed after the lower end of the rotating shaft 4 passes through the material storage ring tube 8 of the material sprayer 2. When the driving motor 3 is working, the rotating centrifugal cylinder 5 can be driven to rotate synchronously through the rotating shaft 4.

[0024] The outer surface of the rotating centrifugal cylinder 5 is spirally mounted with a plurality of rotating wheels 11. The cross section of the rotating wheel 11 is an "L"-shaped structure, and the rotating wheel 11 is an overall curved arc structure (see the attached manual). Figure 3 and 6 The purpose of setting the rotating wheel 11 in this way is that when the high-viscosity polymer mother liquid falls into the space between the rotating centrifugal cylinder 5 and the rotating packing bed 6 during operation, the rotating rotating centrifugal cylinder 5 can use the rotating wheel 11 to "beat out" the high-viscosity polymer mother liquid so that the high-viscosity polymer mother liquid hits the rotating packing bed 6 at high speed, thereby achieving the purpose of dispersing the high-viscosity polymer mother liquid.

[0025] The outer end of the rotating centrifugal cylinder 5 is fixedly provided with a rotating packed bed 6. The rotating packed bed 6 comprises a packing ring net 12 and a fixed plate 13; the lower end of the rotating centrifugal cylinder 5 is provided with a sealing plate 14. The purpose of providing the sealing plate 14 is to seal the bottom of the rotating packed bed 6 through the sealing plate 14, thereby preventing the high-viscosity polymer mother liquid from directly passing through the rotating packed bed 6, resulting in the problem that part of the high-viscosity polymer mother liquid cannot be separated.

[0026] The sealing plate 14 outside the rotating centrifugal cylinder 5 is fixed with a multi-layer packing ring net 12; the upper ends of the multi-layer packing ring net 12 are connected to each other through a plurality of fixing plates 13 (see the attached manual). Figure 5 The purpose of setting the fixing plate 13 is to fix the multi-layer filler ring net 12 through the fixing plate 13 .

[0027] The high-viscosity polymer mother liquid ultra-gravity instant dissolution and maturation device, when in operation, drives the rotating centrifugal cylinder 5 and the rotating packed bed 6 through the rotating shaft 4 to rotate synchronously. During the rotation of the rotating centrifugal cylinder 5 and the rotating packed bed 6, the high-viscosity polymer mother liquid enters the storage ring tube 8 through the drainage tube 7 and is finally sprayed into the space between the rotating centrifugal cylinder 5 and the rotating packed bed 6 through the spray tube 10. The rotating rotating centrifugal cylinder 5 "beats" the high-viscosity polymer mother liquid through the rotating wheel 11 so that the high-viscosity polymer mother liquid hits the rotating packed bed 6 at high speed under the action of centrifugal distribution to form an impact flow, and then continues to flow radially outward under the centrifugal force of the high-speed rotation of the rotating packed bed 6 until it leaves the rotating packed bed 6 and hits the wall of the stationary dispersion tank 1 and falls, thereby achieving the purpose of dispersing the high-viscosity polymer mother liquid. The dispersed high-viscosity polymer mother liquid will eventually be discharged through the discharge pipe 15.

[0028] In this process, due to the strong centrifugal force, the droplets containing powder particles are fully in contact under the environment of efficient dispersion, strong mixing and rapid interface renewal, which greatly enhances the material transfer and surface renewal process and greatly shortens the time for polymer dispersion and dissolution.

[0029] The high-viscosity polymer mother liquor ultra-gravity quick dissolution and maturation device has a compact structure and ingenious design. After the high-viscosity polymer mother liquor is sprayed out by the sprayer 2 onto the high-speed rotating centrifugal cylinder 5, the high-viscosity polymer mother liquor will hit the rotating packing bed 6 at high speed after being centrifugally thrown out by the rotating wheel 11, and will be thrown out under the high-speed rotation of the rotating packing bed 6, so that the purpose of quickly separating the high-viscosity polymer mother liquor can be achieved, thereby solving the problem of low working efficiency in the existing high-viscosity polymer rapid dispersion method, and is particularly suitable for the needs of high-viscosity polymer dispersion.
