Description

Technical Field

[0001] The invention belongs to the technical field of environmentally friendly nano waterproof emulsion emulsification, and in particular relates to an emulsification device and an emulsification method of the environmentally friendly nano waterproof emulsion. Background Art

[0002] The current environmentally friendly nano waterproof emulsion (fluorine-free waterproofing agent) is processed by first adding the materials (isobornyl methacrylate, octadecyl acrylate, glycidyl methacrylate and tripropylene glycol) into the reactor, controlling the temperature within the range of 60-80°C to stir and melt the materials, then adding the dissolved materials into the emulsifier, and adding emulsifiers (octadecyl trimethyl ammonium chloride, stearamidopropyl dimethylamine and fatty alcohol polyoxyethylene ether AEO) for emulsification. After emulsification for a certain period of time, homogenization is carried out. The homogenization process needs to be kept warm (controlled at 35-50°C). After cyclic homogenization, the particle size D50 is 50-100nm, D90 is 100-150nm, and D99 is 200-300nm, which is qualified. In this way, the prepolymer of the nanoemulsion can be obtained. Then, the initiator (azobisisobutylimidazole hydrochloride) is added to initiate the synthesis of the nanoemulsion, and finally vinyl chloride is introduced, and then a chain transfer agent (n-dodecyl mercaptan) is added to react to synthesize a waterproof and oil-proof environmentally friendly treatment liquid.

[0003] Environmentally friendly nano waterproof emulsion requires an emulsification device during the processing. Existing emulsification devices generally use mechanical stirring and high-speed shearing methods. Since the raw materials of environmentally friendly nano waterproof emulsion contain both aqueous and oily phase materials, and the compatibility of aqueous and oily phase materials is poor, the aqueous and oily phase materials are prone to stratification. The stratified materials are difficult to effectively mix by stirring or shearing alone, that is, it is difficult for the layers of materials to contact each other, resulting in uneven mixing of the materials during stirring or shearing, which affects the final emulsification effect.

[0013] The beneficial effects of the present invention are: 1.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0017] like Figure 1-Figure 4 As shown, an emulsifying device for environmentally friendly nano waterproof emulsion includes an emulsifying tank 1, a feeding pipe 2 and a discharge pipe 3, and the device also includes: The drum 4 and the top of the inner cavity of the emulsification tank 1 are provided with a mounting frame 11, and the drum 4 is rotatably mounted in the mounting frame 11; Feed assembly 7, several groups of feed assemblies 7 are arranged on the periphery of the drum 4, and the feed assembly 7 includes a curved pipe 71, one end of the curved pipe 71 is connected to the drum 4 in a tangential state, and the other ends of the several curved pipes 71 are provided with a collecting cover 72, and the open ends of the several collecting covers 72 are all facing the rotation direction of the drum 4, and the length of the open end of the collecting cover 72 is equal to the distance between the outer wall of the drum 4 and the inner wall of the emulsification tank 1; A fixed cylinder 5 is fixed on the top of the inner cavity of the emulsification tank 1. The bottom of the fixed cylinder 5 is hollowed out. The fixed cylinder 5 is located inside the rotating cylinder 4. A space for material to pass through is left between the fixed cylinder 5 and the rotating cylinder 4. A plurality of discharge pipes 51 are provided on the periphery of the fixed cylinder 5. The discharge pipes 51 are located above the rotating cylinder 4. The turbine 9 is provided on the top of the emulsifying tank 1. A rotating rod 8 is rotatably installed. One end of the rotating rod 8 extends into the fixed cylinder 5. A plurality of turbines 9 are provided on the periphery of the rotating rod 8. The plurality of turbines 9 are located in the fixed cylinder 5. A transition cylinder 6 is provided at the bottom of the emulsification tank 1 , the bottom end of the fixed cylinder 5 passes through the bottom of the emulsification tank 1 and extends into the transition cylinder 6 , and the bottom end of the rotating cylinder 4 is rotatably installed at the bottom of the inner cavity of the emulsification tank 1 .

[0018] Furthermore, a slave gear 41 is provided on the periphery of the rotating drum 4, a driving member 12 is installed outside the emulsification tank 1, a main gear 2 122 is provided at the output end of the driving member 12, and the main gear 2 122 and the slave gear 41 are engaged with each other, and a slave gear 2 81 is provided at one end of the rotating rod 8 located outside the emulsification tank 1, and a main gear 121 is also provided at the output end of the driving member 12, and the main gear 121 and the slave gear 2 81 are engaged with each other.

[0019] In actual application of this embodiment, a plurality of materials and a plurality of emulsifiers are added to the emulsifying tank 1 through the feeding pipe 2, and then the driving member 12 is started. The driving member 12 rotates the main gear 121 and the main gear 2 122, and cooperates with the slave gear 1 41 and the slave gear 2 81 to rotate the drum 4 and the rotating rod 8. When the drum 4 rotates, it drives the plurality of feeding components 7 to rotate. The material and emulsifier enter the curved pipe 71 through the collecting cover 72, and then enter the drum 4 in a tangential state through the curved pipe 71. Compared with the material and emulsifier entering the drum 4, the drum 4 is in a stationary state. After entering the drum 4, the material and emulsifier will generate angular motion due to inertia. A spiral downward vortex is formed between the rotating drum 4 and the fixed drum 5. The material and emulsifier entering the rotating drum 4 through the plurality of bends 71 ​​also form a spiral downward vortex. In such a high-speed vortex, the velocity gradient (shear force) between the material and emulsifier layers will tear the fluid microclusters apart, increase the contact area, and accelerate diffusion, thereby uniformly mixing the plurality of materials and emulsifiers and enhancing the emulsification effect. After the mixed material and emulsifier enter the transition drum 6, they are guided by the conical seat 61 and the suction generated by the rotation of the plurality of turbines 9, causing the material and emulsifier to flow upward in the fixed drum 5 and finally be discharged back to the liquid surface through the discharge pipe 51. The collecting covers 72 collect materials or emulsifiers at different heights, so that materials or emulsifiers in different layers can gradually enter the space between the rotating drum 4 and the fixed drum 5. In this way, under the action of the swirling flow, radial cross-penetration of materials and emulsifiers in different layers is promoted, the contact frequency of different fluid layers is increased, thereby breaking the layered structure, further making the materials and emulsifiers evenly mixed, and further enhancing the emulsification effect; When the materials and emulsifiers pass through the turbines 9, the turbines 9 perform multi-stage guided acceleration on the materials and emulsifiers, so that the materials and emulsifiers form a vortex again in the fixed cylinder 5 and contact and collide multiple times, so that the materials and emulsifiers contact and mix again, so that the materials and emulsifiers are evenly mixed, and the emulsification effect is further enhanced.

[0020] Furthermore, a plurality of groups of feed assemblies 7 are arranged at equal intervals in a spiral staircase shape.

[0021] In actual application of this embodiment, such an arrangement ensures that when the collecting covers 72 at different layers collect the material and emulsifier, the material and emulsifier in the emulsification tank 1 will not be shaken violently, thereby effectively avoiding collection dead corners and preventing the material and emulsifier in the highest layer from moving upward due to shaking and being unable to be collected. In this way, it is ensured that most of the material and emulsifier can gradually enter between the rotating drum 4 and the fixed drum 5 for mixing and emulsification, thereby enhancing the emulsification effect; This arrangement makes the multiple feed holes on the periphery of the rotating drum 4 present a spiral staggered state, so that the angular momentum of different layers of materials and emulsifiers is gradually superimposed when entering between the rotating drum 4 and the fixed drum 5, forming a stronger overall vortex. This can effectively increase the rotation speed of the vortex, promote shear and collision between different layers of materials and emulsifiers, thereby further evenly mixing the multiple materials and emulsifiers, and further enhancing the emulsification effect; This arrangement ensures that after different layers of materials and emulsifiers enter between the rotating drum 4 and the fixed drum 5, the rotational kinetic energy of the multi-stage swirl is transmitted step by step instead of being dissipated centrally, thereby reducing local pressure loss and improving energy utilization, thereby ensuring continuous swirl and continuous mixing and emulsification of materials and emulsifiers, thereby further evenly mixing multiple materials and multiple emulsifiers and further enhancing the emulsification effect.

[0022] Furthermore, the inner diameters of the plurality of curved pipes 71 decrease sequentially from top to bottom.

[0023] In actual application of this embodiment, a larger inner diameter of the elbow 71 can reduce the resistance to the flow of materials and emulsifiers, thereby increasing the flow rate and flow velocity of the materials and emulsifiers entering the drum 4 per unit time; while a smaller inner diameter of the elbow 71 will increase the resistance to the flow of materials and emulsifiers, restrict the flow rate and cause a decrease in the flow velocity; this arrangement allows the speed of the materials and emulsifiers passing through the uppermost elbow 71 to be faster, while the speed of the materials and emulsifiers passing through the lowermost elbow 71 to be slower, so that the materials and emulsifiers with lower density on the uppermost side form a high-speed vortex to impact the vortex formed by the materials and emulsifiers with higher density below, so that the materials and emulsifiers with lower density can be fully and effectively mixed with the materials and emulsifiers with higher density, that is, the materials and emulsifiers on the upper layer can be fully and effectively mixed with the materials and emulsifiers on the lower layer, so that multiple materials and multiple emulsifiers are mixed evenly, further enhancing the emulsification effect.

[0024] Furthermore, the lengths of the plurality of curved pipes 71 increase sequentially from top to bottom.

[0025] In actual application of this embodiment, the shorter the length of the bend 71, the less resistance along the way, thereby further accelerating the flow rate; while the longer the length of the bend 71, the more resistance along the way and suppresses the flow rate; this arrangement further accelerates the speed of the material and emulsifier passing through the uppermost bend 71, while further slows down the speed of the material and emulsifier passing through the lowermost bend 71, so that the material and emulsifier in the upper layer can collide with the material and emulsifier in the lower layer at a higher flow rate, thereby further fully and effectively mixing the material and emulsifier in the upper layer with the material and emulsifier in the lower layer, further evenly mixing the multiple materials and multiple emulsifiers, and further enhancing the emulsification effect.

[0026] like Figure 5 and Figure 6 As shown, a shearing piece 10 is installed on the periphery of the rotating rod 8, and the shearing piece 10 is located in the fixed cylinder 5. The shearing piece 10 includes a sleeve 101, and the sleeve 101 is rotatably sleeved on the periphery of the rotating rod 8. A plurality of support plates 102 and a plurality of guide plates 103 are provided on the periphery of the sleeve 101. The other sides of the support plates 102 and the guide plates 103 are fixed on the inner wall of the fixed cylinder 5. The support plates 102 and the guide plates 103 are arranged at intervals, and both sides of the guide plates 103 are provided with upwardly expanded and curved arc guide surfaces.

[0027] In actual application of this embodiment, when the material and emulsifier flow upward in the fixed cylinder 5, they will pass through the shearing piece 10. After the material and emulsifier pass through the position between the support plate 102 and the guide plate 103, the material and emulsifier flow upward obliquely. There are two symmetrical streams of material and emulsifier fluid on both sides of the support plate 102, which makes the two streams of material and emulsifier fluid collide with each other and mix again, thereby further mixing the multiple materials and multiple emulsifiers evenly and further enhancing the emulsification effect. like Figure 2 、 Figure 3 and Figure 7 As shown, a plurality of triangular rods 111 are provided on the top of the mounting frame 11 , and the top ends of the triangular rods 111 are fixed to the top of the inner cavity of the emulsification tank 1 .

[0028] During actual application of this embodiment, the rotating drum 4 rotates between the mounting frame 11 and the fixed drum 5, so that the rotating drum 4 is restricted, thereby improving the stability of the rotating drum 4 during rotation; after the mixed material and emulsifier are ejected from the discharge pipe 51, the discharge pipe 51 and the triangular rod 111 are relatively stationary, so that the material and emulsifier collide with the triangular rod 111, and since one triangular side of the triangular rod 111 faces the discharge pipe 51, the material and emulsifier are split into two parts after colliding with the triangular rod 111, and contact the inclined surface of the triangular rod 111, so that the material and emulsifier are repeatedly broken and reorganized, thereby further evenly mixing the multiple materials and the multiple emulsifiers, and further enhancing the emulsification effect.

[0029] An emulsification method for an environmentally friendly nano waterproof emulsion emulsification device, the method is applied to the above-mentioned environmentally friendly nano waterproof emulsion emulsification device, the method comprising the following steps: Step S1: adding a plurality of materials and a plurality of emulsifiers into the emulsification tank 1 through the feeding pipe 2; Step S2: Starting the driving member 12 to rotate the drum 4 and the rotating rod 8, the drum 4 drives the plurality of feeding assemblies 7 to rotate, and the plurality of materials and the plurality of emulsifiers enter the space between the drum 4 and the fixed drum 5 through the feeding assemblies 7. After entering, the plurality of materials and the plurality of emulsifiers flow downward in a spiral state, so that the plurality of materials and the plurality of emulsifiers are mixed and emulsified. After the plurality of materials and the plurality of emulsifiers flow into the transition drum 6, the plurality of turbines 9 are driven by the rotating rod 8 to cause the plurality of materials and the plurality of emulsifiers to flow upward; Step S3: the upwardly flowing materials and emulsifiers are further mixed and emulsified through the shearing element 10; Step S4: the mixed and emulsified materials and emulsifiers finally return to the liquid surface through the discharge pipes 51 , and the emulsion formed after the mixing and emulsification is discharged through the discharge pipe 3 .
