[0039] Preferably, the functional fiber is polyacrylonitrile-sodium alginate composite fiber.

[0040] The art paint preparation device comprises a stirring kettle 1, a driving motor 2 fixedly connected to the middle of the upper end surface of the stirring kettle 1, a feed pipe 3 fixedly communicated with one side of the upper end surface of the stirring kettle 1, a base 4 fixed to the lower end surface of the stirring kettle 1, and a discharge pipe 5 fixedly communicated with one side of the lower end surface of the stirring kettle 1, wherein a control valve is arranged in the discharge pipe 5.

[0041] The stirring kettle 1 is internally provided with a stirring and crushing mechanism 7, and the bottom of the stirring kettle 1 is provided with an air flotation mechanism 6.

[0042] The stirring and crushing mechanism 7 comprises stirring blades 71, crushing blades 72, and a stirring shaft 73. The stirring blades 71 and the crushing blades 72 are driven to rotate by the stirring shaft 73, so as to uniformly stir the internal paint raw materials and further crush the paint nodules, thereby better mixing and reacting the paint nodules.

[0043] The air flotation mechanism 6 comprises a reciprocating wire rod 61, an extrusion plate 63, an air bag 64, an air flotation plate 65, and a spray head. The reciprocating wire rod 61 is driven to rotate, the extrusion plate 63 is driven to reciprocate up and down to extrude the air bag 64, the gas in the air bag 64 is delivered to the bottom of the stirring kettle 1 to generate air bubbles, the air bubbles push the sedimentary particulate materials upward, reduce the stirring blind area, and accelerate the reaction of the particulate sedimentary materials, which are further stirred and crushed by the stirring and crushing mechanism 7.

[0044] As an embodiment of the present application, as shown inFigure 2 、 Figure 3 With Figure 5 As shown in the figure, the upper end of the stirring shaft 73 in the stirring and crushing mechanism 7 is fixedly connected with the output shaft of the driving motor 2, and the lower end of the stirring shaft 73 is rotatably connected with the bottom of the stirring kettle 1. The number of the stirring blades 71 is at least eight, which are symmetrically distributed and fixed on both sides of the stirring shaft 73. The end of the stirring blade 71 away from the stirring shaft 73 is fixed with a crushing blade 72. The end of the crushing blade 72 away from the stirring blade 71 is fixedly connected with a rotating shaft 74, and the end of the rotating shaft 74 away from the crushing blade 72 is rotatably connected with a roller 75. The inner wall of the stirring kettle 1 is provided with a slanting annular groove 76 at the corresponding position of the roller 75, and the slanting annular groove 76 is designed in a wave shape. The roller 75 rolls in the slanting annular groove 76 and cannot be separated. The stirring blade 71 and the crushing blade 72 are both made of high-toughness metal, and the adjacent surface of the crushing blade 72 is provided with a convex point.

[0045] Through the above technical scheme, when working, the user first puts the paint raw materials into the stirring kettle 1 through the feeding pipe 3 according to the proportion, and then starts the driving motor 2 to conduct electricity. The driving motor 2 drives the stirring shaft 73 to rotate through the output shaft, and the stirring shaft 73 further drives the stirring blade 71 and the crushing blade 72 connected therewith to rotate in the stirring kettle 1 to stir the internal paint raw materials. In the stirring process, nodules of paint raw materials may appear. In the rotating process of the crushing blade 72, the roller 75 connected with the rotating shaft 74 rolls and moves in the slanting annular groove 76. Since the slanting annular groove 76 is designed in a wave shape, the adjacent rollers 75 move up and down in the wave-shaped slanting annular groove 76. Under the connection of the rotating shaft 74, the crushing blade 72 and the stirring blade 71 are made of high-toughness metal, so the crushing blade 72 also bends up and down. When the adjacent crushing blades 72 bend, the distance between the adjacent crushing blades 72 becomes smaller until the adjacent surfaces contact. At this time, the nodules of paint between the crushing blades 72 are crushed by the crushing blades 72 cooperating with the convex points to complete the crushing work of the nodules of paint. The stirring blade 71 can better cooperate with the crushing blade 72 to carry out the mixing reaction.

[0046] As an embodiment of the present application, as Figure 5 With Figure 6As shown, the upper end of the reciprocating wire rod 61 in the air float mechanism 6 is fixed with the bottom end of the stirring shaft 73, the outer sleeve 62 is fixedly connected outside the reciprocating wire rod 61 at the bottom of the stirring kettle 1, the outer surface of the reciprocating wire rod 61 is screw transmission connected with the extrusion plate 63, the outer diameter of the extrusion plate 63 is consistent with the inner diameter of the outer sleeve 62, the air bag 64 is sleeved outside the reciprocating wire rod 61 without contacting the reciprocating wire rod 61, the bottom of the air bag 64 is fixed with the upper end surface of the extrusion plate 63, the upper end of the air bag 64 is fixed with the lower end surface of the stirring kettle 1, the air float plate 65 is fixedly connected inside the bottom end of the stirring kettle 1, a plurality of nozzles are fixedly connected with the upper end surface of the air float plate 65, the inside of the air float plate 65 is provided with an air channel in communication with the nozzles, the upper end of the air bag 64 is provided with a gas injection hole 66 in communication with the air channel, the lower end surface of the extrusion plate 63 is provided with a gas suction hole in communication with the air bag 64, and the gas suction hole is provided with a one-way valve inside the gas injection hole 66.

[0047] By adopting the above technical scheme, in the rotating process of the stirring shaft 73, the particulate matter existing in the internal coating may sink to the bottom of the stirring kettle 1 under the action of its own gravity, and the stirring blade 71 is difficult to well contact and stir and mix with it, and there is a stirring blind area, so that in the rotating process of the stirring shaft 73, the reciprocating wire rod 61 connected with the stirring shaft 73 also rotates, at this time the extrusion plate 63 screw transmission connected with the reciprocating wire rod 61 reciprocates up and down inside the outer sleeve 62, at this time the air bag 64 located on the extrusion plate 63 is continuously extruded and stretched, when the air bag 64 is extruded, the one-way valve of the gas suction hole is closed, the gas is transported to the air channel in the air float plate 65 through the exhaust hole and is sprayed out by the nozzle, since the coating is a viscous liquid, a large amount of bubbles is generated by the gas spraying, the bubbles float up to push the particulate deposits of the bottom plate of the stirring kettle 1 to make it contact with the stirring blade 71 for stirring or even cooperate with the crushing blade 72 for crushing treatment, when the extrusion plate 63 moves downward, the air bag 64 is stretched, at this time the one-way valve of the gas injection hole 66 is closed, the gas suction hole is opened to extract air from the outside to supplement the gas consumption in the air bag 64, when the coating processing is completed, the processed coating can be discharged through the discharge pipe 5.

[0048] Working principle:

[0049] When in use, first of all, the user will put the paint raw materials into the stirring kettle 1 through the feeding pipe 3 according to the proportion, then start the driving motor 2 to drive the stirring shaft 73 to rotate through the output shaft, and the stirring shaft 73 further drives the stirring blades 71 and the crushing blades 72 connected therewith to rotate in the stirring kettle 1 to stir the internal paint raw materials. In the stirring process, the paint raw materials may form nodules, and in the rotating process of the crushing blades 72, the rollers 75 connected with the rotating shaft 74 roll and displace in the inclined annular grooves 76. Since the inclined annular grooves 76 are designed in a wave shape, the adjacent rollers 75 displace up and down in the wave-shaped inclined annular grooves 76. Under the action of the high-toughness metal of the crushing blades 72 and the stirring blades 71, the crushing blades 72 will also bend up and down. When the adjacent crushing blades 72 are bent, the distance between the adjacent crushing blades 72 becomes smaller until the adjacent surfaces contact. At this time, the nodules of the paint between the crushing blades 72 are crushed by the crushing blades 72 cooperating with the convex points to complete the crushing work of the nodules of the paint, and the stirring blades 71 can better cooperate with the crushing blades 72 to carry out the mixing reaction.

[0050] In the rotating process of the stirring shaft 73, the particles in the internal paint may sink to the bottom of the stirring kettle 1 under the action of their own gravity, and the stirring blades 71 cannot well contact with them for stirring and mixing, so there is a stirring blind area. Therefore, in the rotating process of the stirring shaft 73, the reciprocating screw rod 61 connected with the stirring shaft 73 also rotates. At this time, the extrusion plate 63 connected with the reciprocating screw rod 61 through the screw transmission will displace up and down in the outer sleeve 62. At this time, the air bag 64 on the extrusion plate 63 will be continuously extruded and stretched. When the air bag 64 is extruded, the air inlet one-way valve is closed, the gas is transported to the air duct in the air floating plate 65 through the exhaust hole and is sprayed out by the nozzle. Since the paint is a viscous liquid, a large amount of bubbles will be generated when the gas is sprayed out. The bubbles float up to push the particle deposits on the bottom plate of the stirring kettle 1 to contact with the stirring blades 71 for stirring or even cooperate with the crushing blades 72 for crushing treatment. When the extrusion plate 63 moves downward, the air bag 64 is stretched. At this time, the air injection hole 66 one-way valve is closed, and the air inlet is opened to extract air from the outside to supplement the gas consumption in the air bag 64. When the paint processing is completed, the processed paint can be discharged through the discharge pipe 5.

[0051] The stirring and crushing mechanism 7 includes stirring blades 71, crushing blades 72 and a stirring shaft 73, the stirring blades 71 and the crushing blades 72 are driven to rotate by the stirring shaft 73, which can uniformly stir the internal paint raw materials, further crush the paint nodules, and better mix and react; the air floating mechanism 6 includes a reciprocating wire rod 61, an extrusion plate 63, an air bag 64, an air floating plate 65 and a nozzle, the reciprocating wire rod 61 is driven to rotate, the extrusion plate 63 is driven to reciprocate up and down to extrude the air bag 64, the gas in the air bag 64 is delivered to the bottom of the stirring kettle 1 to generate bubbles, the sedimentary particulate materials are pushed upward, the stirring blind area is reduced, and the reaction of the particulate sedimentary materials is accelerated, which is further stirred and crushed by the stirring and crushing mechanism 7.

[0052] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
