[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] See also Figure 1 - Figure 7 The present application provides a device for uniformly adding papermaking additives for papermaking, comprising:

[0037] A frame 100, wherein an additive adding barrel 101 for mixing powdered additives is vertically arranged inside the frame 100;

[0038] The mixing mechanism 200 installed inside the additive adding barrel 101 can fully disperse the powder additive. The mixing mechanism 200 can not only fully stir to help the additive powder mix with water, but also cut and disperse the two during mixing, so that the powder will not float on the liquid surface during the mixing process. The full mixing makes it easier to add the solution into the papermaking pot, thereby improving the papermaking quality. At the same time, the scraper ring 206 will change the stirring height, and there will be no mixing dead corner.

[0039] The mixing mechanism 200 includes a fixed twisted rod 204 vertically installed in the additive adding barrel 101, a scraper ring 206 rotating and moving along the fixed twisted rod 204, a driving cylinder 201 driving the scraper ring 206 to rise and fall, and a plurality of scraper knives 207 for scraping the additive at the bottom of the additive adding barrel 101. During the downward movement of the scraper ring 206, the powder on the inner wall of the additive adding barrel 101 can be scraped down to facilitate full mixing. The upper surface of the scraper ring 206 is inclinedly provided with an inclined scraper plate 2082 that fits the inner wall of the additive adding barrel 101, so as to facilitate scraping the material on the inner wall of the additive adding barrel 101;

[0040] The scraper ring 206 is provided with a turning member 208 for driving a plurality of scraper blades 207 to deflect in angles. The deflection of the scraper blades 207 breaks up the granular additives on the liquid surface and fully mixes them with the liquid.

[0041] In this embodiment, preferably, a spiral disc 203 is sleeved on the fixed twisted rod 204, and a plurality of scraper knives 207 are arranged on the circumference between the outer circumference of the spiral disc 203 and the inner circumference of the scraper ring 206. When the scraper knives 207 are in a vertical direction, the back of the scraper knives 207 is flush with the lower surface of the scraper ring 206. Two driving cylinders 201 are vertically arranged on the upper surface of the additive adding barrel 101. The connecting rod 202 inside the driving cylinder 201 penetrates the additive adding barrel 101 and extends to the inside, and A ball head slider 210 is provided at the lower end of the connecting rod 202, and an annular groove 209 is provided on the upper surface of the spiral disk 203 for the ball head slider 210 to extend into. The two are slidably connected, which does not affect the rotation of the spiral disk 203 and is convenient for driving the spiral disk 203 to move along the fixed twisted rod 204. An annular plate matching the notch can be provided in the annular groove 209, and the annular plate is sleeved on the connecting rod 202, which reduces the liquid from entering the annular groove 209 and does not affect the rotation of the spiral disk 203.

[0042] In this embodiment, preferably, the flip member 208 includes a connecting ring 2081 located above the scraper ring 206. The flip member 208 can be used to change the angle of the scraper 207, which can not only break up the powder agglomerated on the liquid surface, but also facilitate the pushing of the solution at the bottom of the auxiliary agent adding barrel 101 to reduce solution residue. A mounting shaft 2084 is provided between the inner and outer ends of the scraper 207 and the spiral disk 203 and the scraper ring 206 to facilitate the rotation of the scraper 207 around the mounting shaft 2084. A flip gear 2085 is sleeved on the outermost mounting shaft 2084. A movable rack 2086 is meshed on the inner side of the flip gear 2085. A mounting shaft 2084 is provided between the lower surface of the connecting ring 2081 and the outer surface of the movable rack 2086. The fixed plate 2087 can drive the fixed plate 2087 to move as the connecting ring 2081 moves, thereby driving the moving rack 2086 to move. A lifting cylinder 2083 is vertically arranged on the upper surface of the scraper ring 206. The lifting cylinder 2083 will not exceed the outer circumference of the scraper ring 206, and a cylindrical protective shell is arranged on the upper surface of the scraper ring 206 to protect the lifting cylinder 2083. An extension plate 2088 is arranged between the piston rod inside the lifting cylinder 2083 and the outer circumference of the connecting ring 2081, and a telescopic sealing tube and a fixed circular plate are arranged between the piston rod and the lifting cylinder 2083. The telescopic sealing tube and the fixed circular plate will not affect the extension and retraction of the piston rod and can also seal the connection between the piston rod and the lifting cylinder 2083.

[0043] In summary, when in use, the auxiliary agent powder is put into the auxiliary agent adding barrel 101 through the feed port 102, and water is injected into the auxiliary agent adding barrel 101. At this time, the scraper ring 206 is located at the bottom of the auxiliary agent adding barrel 101, and the inner rod inside is in an extended state. The driving cylinder 201 works, and the inner rod drives the connecting rod 202 to move upward. The ball head slider 210 cooperates with the annular slide groove 209 to drive the spiral disc 203 to rotate and move upward along the fixed twisted rod 204. At this time, the lifting cylinder 2083 works, and the internal piston rod extends to drive the connecting ring 2081 to move upward, drive the extension plate 2088 and the fixed plate 2087 to move upward, drive the moving rack 2086 to move upward, drive the flip gear 2085 meshing with it to rotate, drive the mounting shaft 2084 and the scraper knife 207 to rotate, so that the scraper knife 207 forms a certain angle with the vertical direction, and the blade surface is inclined. As the scraper ring 206 rotates, it drives the multiple The scraper blades 207 rotate and move upward to fully mix the additive powder with water, and the scraper ring 206 will scrape the material on the inner wall of the additive adding barrel 101 and mix it with water again when it moves to the liquid surface. When it moves to the liquid surface, the driving cylinder 201 can stop working, and the rotating component 205 drives the scraper ring 206 and multiple scrapers 207 to rotate continuously at the liquid surface. The blade surfaces of the rotating scrapers 207 continuously break up the additive powder floating on the liquid surface, break up the clumped additive powder and fully mix it with water. After mixing for a period of time, the rotating component 205 stops working, and the driving cylinder 201 works again to move the connecting rod 202 downward, driving the spiral disk 203 to rotate and rotate downward to mix again, and scrape the material on the inner wall of the additive adding barrel 101 again. In the whole process, the additive powder and water are fully mixed, and no clumping occurs, which is convenient for forming a uniform solution to be added to the papermaking pot, thereby improving the papermaking quality.

[0044] Embodiment 2

[0045] Reference Figure 8 , which is the second embodiment of the present invention.

[0046] In this embodiment, preferably, a rotating member 205 is provided between the driving cylinder 201 and the frame 100. By providing the rotating member 205, the scraper ring 206 can only rotate at a certain position without moving, which is convenient for fully mixing the auxiliary powder with water and continuously rotating to break up the agglomerated powder floating on the liquid surface, and the scraper ring 206 can continuously rotate to facilitate pushing the material. The rotating member 205 is used to drive the two driving cylinders 201 to rotate synchronously. The rotating member 205 includes a top plate 2051 horizontally fixed on the top of the frame 100, the top plate 2051 is located above the auxiliary agent adding barrel 101, and a rotatable rotating disk 2052 is embedded in the top plate 2051. A mounting disk 2054 is rotatably provided on the top of the auxiliary agent adding barrel 101, and the mounting disk 2054 is rotatably connected to the auxiliary agent adding barrel 101 and is installed A fixed twisted rod 204 is provided at the center of the lower surface of the disk 2054. The mounting disk 2054 does not affect the up and down movement of the connecting rod 202. The two driving cylinders 201 are embedded and installed in the rotating disk 2052. The rotating disk 2052 is rotatably connected to the top plate 2051, and the connecting rods 202 inside the two driving cylinders 201 are movably passed through the mounting disk 2054 and exposed below. The connecting rods 202 are connected to the inner rods inside the driving cylinders 201. An outer gear ring 2053 is sleeved on the upper end of the rotating disk 2052. An outer gear 2055 is meshed with the outer side of the outer gear ring 2053. A driving motor 2056 for driving the outer gear 2055 to rotate is provided on the top of the top plate 2051. The driving motor 2056 can drive the outer gear 2055 to rotate, thereby driving the outer gear ring 2053 and the rotating disk 2052 meshed therewith to rotate.

[0047] In summary, when the scraper ring 206 needs to rotate, the inner rod inside the drive cylinder 201 will not drive the connecting rod 202 to extend and retract, so the spiral disk 203 and the fixed twisted rod 204 will not rotate. For example, after the auxiliary agent solution is discharged, there is still liquid remaining at the bottom of the auxiliary agent adding barrel 101. At this time, the scraper ring 206 is located at the bottom of the auxiliary agent adding barrel 101, and the drive cylinder 201 does not work. The scraper ring 206 will not move with the spiral disk 203, allowing the drive motor 2056 to work, driving the outer gear 2055 to rotate, and the outer gear ring 2053 and the rotating disk 2052 meshing therewith rotate, driving the two drive cylinders 201 to rotate synchronously, and the connecting rod 202 is connected to the mounting disk 2054, so the mounting disk 2054 and the rotating disk 2052 are connected. The disk 2052 rotates synchronously, so that the fixed twisted rod 204 fixed on the lower surface of the mounting disk 2054 and the spiral disk 203 connected to the connecting rod 202 rotate synchronously. At this time, the back of the scraper 207 contacts the bottom of the additive adding barrel 101. As the scraper ring 206 rotates, the solution remaining at the bottom of the barrel is pushed toward the liquid inlet pipe 302, and the residual solution is pushed into the liquid inlet pipe 302, thereby reducing the waste of residual solution. Similarly, if the scraper ring 206 moves to the liquid level, the scraper ring 206 can be allowed to rotate without moving. At this time, the scraper 207 is tilted, and the blade surface is tilted close to horizontal. As it rotates, the blade surface will rotate to cut the agglomerated powder on the liquid surface, break up the agglomerated powder, increase the sufficient dissolution of the additive powder, and facilitate subsequent uniform addition into the papermaking pot.

[0048] Embodiment 3

[0049] Reference Fig. 9 , which is the third embodiment of the present invention.

[0050] In this embodiment, preferably, a feeding and adding component 300 for adding an additive solution to the papermaking pot body is provided at the bottom of the additive adding barrel 101. By providing the feeding and adding component 300, the additive solution can be added circumferentially in the papermaking pot, and the additive solution will not fall in only one place, which is convenient for the additive solution to be fully mixed with the slurry in the papermaking pot, thereby improving the papermaking quality and the convenience of adding the additive solution. The feeding and adding component 300 includes a feeding barrel 301 located below the eccentric position of the additive adding barrel 101, and a liquid inlet pipe 302 is provided between the feeding barrel 301 and the additive adding barrel 101. The liquid inlet pipe 302 is located at the center of the discharge barrel 301, and the solution is discharged directly to the bottom of the discharge barrel 301. A flow valve is arranged on the liquid inlet pipe 302. A plurality of inclined holes 304 are opened along the circumferential direction of the upper end of the discharge barrel 301. A piston pushing plate 303 is arranged near the lower end of the discharge barrel 301. A pushing cylinder 307 is arranged below the discharge barrel 301. The pushing rod inside the pushing cylinder 307 extends to the inside of the discharge barrel 301 and is fixed to the lower surface of the piston pushing plate 303. A stabilizing frame 306 supported and reinforced by the pushing cylinder 307 is arranged on the lower surface of the discharge barrel 301.

[0051] In this embodiment, preferably, the inclined material hole 304 is a downwardly inclined hole, so that the additive solution falls into the papermaking pot at an angle downward when discharged, and a reinforcing plate 305 is arranged between the top of the lower material barrel 301 and the additive adding barrel 101 to increase the installation strength of the lower material barrel 301. A feed port 102 is arranged on the top of the additive adding barrel 101 to facilitate the addition of additive powder into the lower material barrel 301 from the feed port 102.

[0052] In summary, open the flow valve to allow the fully mixed auxiliary solution to enter the discharge barrel 301 through the liquid inlet pipe 302. When the discharge solution reaches a certain amount, close the flow valve. At this time, the solution in the discharge barrel 301 will not exceed the height of the inclined material hole 304. The pushing cylinder 307 works, and the internal piston rod extends to drive the piston pushing plate 303 to move upward, pushing the auxiliary solution in the discharge barrel 301 upward, and under the squeezing action of the piston pushing plate 303, it is evenly discharged from multiple inclined material holes 304, and the auxiliary solution falls evenly in the papermaking pot in a circular direction. During the stirring process of the papermaking pot, the auxiliary solution will not fall on only one place, so that the auxiliary solution is added to the papermaking pot evenly, which is convenient for the auxiliary solution to be fully mixed with the slurry in the papermaking pot, thereby improving the papermaking quality.

[0055] When in use, the mixing mechanism 200 is used to fully mix the additive powder and water in the additive adding barrel 101, and the rotating component 205 is used to drive multiple scrapers 207 to break up the clumped powder. The inner wall of the additive adding barrel 101 can be scraped while stirring, and the rotating component 205 can also facilitate the discharge of the mixed solution. After sufficient mixing, the discharge adding component 300 is used to evenly discharge the material into the papermaking pot to expand the discharge area and facilitate the full mixing of the solution and the slurry.

[0056] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
