[0024] As Figures 1 - 3 shown, a chemical additive mixing device for paper production includes a tank body 1 and a top cover 2 detachably connected to the opening end of the tank body 1. A stirring mechanism for mixing chemical additives is provided on the top cover 2; several groups of nozzles 3 capable of spraying chemical additives into the tank body 1 are provided on the top cover 2; two groups of air ducts 4 symmetrically arranged along the central axis are provided on the outer periphery of the tank body 1. An ion blower 5 is provided at one end of one air duct 4 away from the tank body 1, and a filter 6 is provided at one end of the other air duct 4 away from the tank body 1; both groups of air ducts 4 are communicated with the inside of the tank body 1, and the ion blower 5 can input ion wind into the tank body 1 through the air duct 4.

[0025] When the ion blower 5 is working, it can input ion wind into the tank body 1 through the air duct 4. A variety of chemical additives with different charges enter the tank body 1 in a spraying manner through multiple groups of nozzles 3, enabling the chemical additives to fully contact the ion wind; the ion wind generated by the ion blower 5 carries a large amount of positive and negative charges, which can fully neutralize the different charges in the chemical additives. At the same time, the stirring mechanism is started to stir and mix the chemical additives that have removed different charges. The chemical additive mixing device in this technical solution can fully neutralize the different charges between chemical additives through ion wind, reduce the electrostatic repulsion force, and thus improve the mixing effect.

[0026] Above, as Figure 3As shown in the figure, the stirring mechanism includes a driving motor 7 provided on the top cover 2. The driving motor 7 is connected by a coupling 8 to a stirring shaft 9 that can be placed inside the tank body 1. A number of groups of L-shaped brackets 10 are provided on the outer periphery of the stirring shaft 9, and a multi-blade stirring paddle 11 is rotatably connected to each group of L-shaped brackets 10. The rotation axis of the multi-blade stirring paddle 11 is parallel to the rotation axis of the stirring shaft 9. When the driving motor 7 drives the stirring shaft 9 to rotate, the resistance between the multi-blade stirring paddle 11 and the chemical additive can drive the multi-blade stirring paddle 11 to rotate, thereby causing the multi-blade stirring paddle 11 to disrupt the flow direction of the chemical additive and achieving the effect of accelerating the mixing of the chemical additive.

[0027] Further, as Figure 3 shown, a spiral stirring blade 12 is provided on the outer periphery of the stirring shaft 9. When the spiral stirring blade 12 rotates, it can turn up the chemical additive located at the bottom of the tank body 1 or push the chemical additive located at the upper part of the tank body 1 towards its bottom. Cooperating with the multi-blade stirring paddle 11, it can mix the chemical additive in the tank body 1 from multiple directions.

[0028] In this embodiment, the air duct 4 is in a flat shape to increase the coverage area of the ionic wind in the tank body 1 and facilitate the contact between the chemical additive and the ionic wind.

[0029] Further, as Figure 3 shown, an inverted U-shaped part 401 is provided on the air duct 4 to prevent the droplet-shaped chemical additive from being discharged from the tank body 1 through the air duct 4, causing unnecessary waste.

[0030] In this technical solution, each group of nozzles 3 is connected to a feed pipe, and a flow control valve and a metering pump are provided on the feed pipe to accurately control the feed amount of each chemical additive and ensure the accuracy of the mixing ratio.

[0031] Further, a flange discharge port 101 is provided at the bottom of the tank body 1. The flange discharge port 101 can be connected to equipment such as a water pump so that the chemical additive can be output promptly after being mixed.

[0032] Working principle: When the ion blower 5 is working, it can input ionic wind into the tank body 1 through the air duct 4. A variety of chemical additives with different charges enter the tank body 1 in a spraying manner through multiple groups of nozzles 3, enabling the chemical additives to fully contact the ionic wind. The ionic wind generated by the ion blower 5 carries a large amount of positive and negative charges, which can fully neutralize the different charges in the chemical additives. Subsequently, the stirring mechanism is started, and the driving motor 7 drives the stirring shaft 9 and the multi-blade stirring paddle 11 to rotate, stirring and mixing the chemical additives. The chemical additive mixing device in this technical solution can fully neutralize the different charges between the chemical additives through the ionic wind, reduce the electrostatic repulsion force, and thus improve the mixing effect.

[0033] Based on the inspiration of the ideal embodiments of the present utility model, through the above description, relevant personnel can completely make various changes and modifications without departing from the technical idea of the present utility model. The technical scope of the present utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
