Description

Technical Field

[0001] The present invention relates to the technical field of nano - coating manufacturing, and specifically to a nano - level energy - saving coating and its preparation equipment. Background Art

[0002] With the development of modern productivity, how to play a role in energy conservation and emission reduction during the operation of thermal equipment is an important development direction. Among the current energy - saving measures for thermal equipment, coating a nano - level energy - saving coating inside the thermal equipment is an important improvement measure. Nano - level energy - saving coatings are divided into heat - radiation type (R - type) and heat - absorption type (ST - type). They respectively rely on increasing the emissivity and heat - absorption rate to keep more heat inside the equipment.

[0003] At present, the main materials of nano - level energy - saving coatings are semiconductor materials and titanium materials. In this case, at high temperatures, after the titanium ions are heated, the valence electron band is excited and rises to the conduction band. As a result, holes (H+) - electrons (e) in the valence electron band and conduction band combine, and this state is called the excited state, which can increase the energy and transform into poly - titanium oxide (TiO2 → TinO2n - 1). Under high - temperature conditions, the surface of the coating facing the fire will present a ceramic state, thereby increasing the thermal emissivity of the coating, keeping the heat energy in the furnace, reducing heat loss, and at the same time having an excellent protective effect on the refractory material of the furnace wall.

[0004] At present, the materials of nano - level energy - saving coatings are mainly nano - level coatings. The components need to be super - refined, and the particles reaching the nano - level should account for more than 40% of the coating. This nano - level energy - saving coating has strong adhesion, penetrates into the substrate without being affected by thermal expansion and contraction, and combines firmly with the substrate, so that the coating does not peel off.

[0005] During the preparation process of the current nano - level energy - saving coatings, nano - level materials need to be mixed with solvents, etc. The existing mixing equipment for nano - level energy - saving coatings often only completes the processing of the coating through the stirring action of a stirrer. This mixing method makes it very easy for nano - level materials to have uneven distribution problems. However, due to the extremely small particle size of nano - level materials.

[0006] At the same time, during the proportioning process of the current nano - level energy - saving coatings, the materials are often added to the proportioning equipment all at once. Although this saves operation steps, the materials cannot be evenly and continuously mixed during stirring, which undoubtedly increases the working pressure of the stirring device during the mixing process. In view of this, in - depth research on the above - mentioned problems has led to the generation of this case. Summary of the Invention

[0032] Beneficial Effects

[0033] The present invention provides a nano-level energy-saving coating and preparation equipment. It has the following beneficial effects: a structural support is used as the main body of the equipment, and a power device, a mixing kettle body and different material storage tanks are respectively integrated in the structural support, so that the nano-level energy-saving coating is accurately mixed in an automatic control manner. During the mixing process, the solid phase material and the liquid phase material are pre-mixed separately, thereby improving the mixing efficiency. The structure is compact and the space is excellent. The mixing ratio is accurate and the mixing efficiency is high. It has the following specific advantages:

[0034] 1. The modular design of the structural support is used to partition the mixing device, material tank and power device, reducing the workload of disassembly and assembly, maintaining the compactness of the structure, thus facilitating subsequent maintenance and management, and reducing the mixing efficiency of high-adhesion premixes;

[0035] 2. The gearbox is linked to the power motor, which has the function of power diversion and can drive the mixer, pre-mixer and liquid pre-mixer at the same time, thus improving the utilization rate of power output and making the structure more compact and convenient for equipment application and layout;

[0036] 3. A premixing batcher is provided on one side of the batching pipeline for solid-phase materials. Through the premixing batcher, the solid-phase materials can be premixed in advance, so that all the solid-phase materials can be fully and evenly mixed before being mixed with the liquid-phase materials, reducing the working pressure of the mixer and making it easier for the solid-phase materials to be dispersed into the nano-scale energy-saving coating;

[0037] 4. A liquid material pre-mixer is provided on the batching pipeline of the liquid-phase material storage tank. Through the liquid material pre-mixer, the solvent and the polymer substrate can also be fully mixed when entering the mixer, making the distribution of the solvent and the substrate in the liquid-phase material more uniform and reducing the pressure on the mixing tank body;

[0038] 5. The end of the premixing batcher generates a high-pressure jet flow through the action of a jet pump and flows into the dispersion adder. The dispersion adder is arranged coaxially with the mixing main shaft. By using the dispersion action of the dispersion adder, the high-pressure jet flow is injected into the material in the mixing kettle body. While the material is dispersed, the shearing force of the mixing equipment is increased, and the mixing efficiency is improved. Combining the above advantages, the problems of low mixing efficiency and uneven mixing that are prone to occur in centralized addition are avoided;

[0039] 6. A disperser structure is installed at the end of the mixer. The disperser structure remains stationary during the rotation of the main shaft. The material is dispersed by the dispersion rod to keep the material in a dispersed state. Cooperating with the high-pressure flushing and carrying device, the pressure inside the mixing main shaft is increased, and the material is ejected and distributed more evenly by the high-pressure carrying action.

Detailed implementation manners

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0055] Please refer to Figures 1 - 13 , the present invention provides an implementation solution: in the energy-saving application process of modern thermal equipment, in order to retain heat in the thermal equipment as much as possible, using nano-scale energy-saving coatings is a common treatment method. At present, the production of nano energy-saving coatings mainly relies on mixing equipment to mix ultra-fine nano-scale additive components such as nano-silica and nano-titanium dioxide with solvents, additives, and polymer substrates. However, due to the small particle size of nano-scale materials, in the mixing process of conventional addition methods, it is very easy to have the problem of agglomeration, which has high requirements for the shear force of the equipment and the processing time, and has high power requirements for the mixing power equipment, thereby making the equipment inconvenient to maintain and use.

[0056] Embodiment 1: To solve the above problems, the present application discloses a preparation device for nano-scale energy-saving coatings. The device uses the structural support 1 as the main support body to support the nano-scale energy-saving coating mixing equipment. Specifically, the structural support 1 is a rectangular frame structure, and the structural support 1 is composed of a main support 11, a power support 12, and a material tank support 13. A mixing kettle body 2 is assembled on the main support 11. The mixing kettle body 2 is used as the main container for mixing. A power device 3 is arranged on the power support 12 and is connected to the mixing kettle body 2. A mixer 5 is arranged in the mixing kettle body 2, and the mixer 5 is connected to the power device 3. The power device 3 can drive the mixer 5 to operate, so that the mixing kettle body 2 works to fully mix the materials entering the mixing kettle body 2. Furthermore, there are no less than 3 mixing material tanks 4 arranged on the material tank support 13, and the mixing material tanks 4 are used as the containers for containing solid materials for mixing;

[0057] In the production process of nano-scale energy-saving coatings, there are not only nano-scale solid materials, but also liquid-phase materials such as polymer substrates, solvents, and other additives. Therefore, there are no less than 3 liquid material storage tanks 8 arranged on the material tank support 13. One side of the liquid material storage tank 8 is connected to a liquid material pre-mixer 81. A switch control valve 84 is arranged at the bottom of the liquid material storage tank 8. The materials in the liquid material storage tank 8 are introduced into the liquid material pre-mixer 81 through a liquid inlet pipe, so that the mixer 5 can mix the liquid-phase materials with the solid materials;

[0058] The material tank support 13 is used to provide support for the mixing material tank 4 and the liquid material storage tank 8. Furthermore, the power support 12, the material tank support 13, and the main support 11 are all connected separately. When disassembling, installing, and overhauling the power device 3, the mixing kettle body 2, the mixing material tank 4, and the liquid material storage tank 8, the corresponding supports can be directly removed, facilitating the operation;

[0059] According to the attached Figure 1 - attached Figure 4 It can be seen that the above-mentioned mixing material tank 4 is a cylindrical tank body. A supporting ring plate 43 is provided at the bottom of the mixing material tank 4. In order to provide materials more accurately, an automatic weighing device 6 is assembled at the bottom of the above-mentioned mixing material tank 4. The supporting ring plate 43 is in contact with the automatic weighing device 6. After taring, the automatic weighing device measures the weight of the materials in the mixing material tank 4. A top cover 44 is provided at the top of the mixing material tank 4. A material level detector 45 and a feeding inlet are provided on the top cover 44. The material level detector 45 detects the material level in the mixing material tank 4. Thus, when the material level is detected and the materials are insufficient, feeding is carried out into the mixing material tank 4 through the feeding inlet. Furthermore, a control gate 46 is provided at the bottom of the above-mentioned mixing material tank 4. Furthermore, the size of the mixing material tank 4 adopts a tank body structure with different volumes according to the proportion of the materials contained. The feeding rate and the feeding amount of the mixing material tank 4 can be controlled through the control gate 46;

[0060] Specifically, the automatic weighing device 6 is installed with the material tank support 13 as the support. A threaded feeder 42 is provided in the feeding pipe 41. The automatic weighing device 6 is supported by the material tank support 13. The mixing material tank 4 is assembled on the automatic weighing device 6 without direct contact with the material tank support 13. The automatic weighing device 6 is integrally provided with the feeding pipe 41. The weight of the materials in the mixing material tank 4 can be measured through the automatic weighing device 6. Furthermore, the materials in the mixing material tank 4 fall into the automatic weighing device 6 under the action of gravity. The automatic weighing device 6 is connected to the feeding pipe 41. The weighed materials are conveyed to the premixing device 7 by the threaded feeder 42;

[0061] Multiple mixing material tanks 4 are respectively used to contain nano-titanium dioxide and nano-silica. These two materials are both nano-scale solid-phase materials. In order to improve the mixing uniformity, a premixing device 7 is connected between the feeding pipes 41 of the multiple mixing material tanks 4. The premixing device 7 is used to premix the materials in the feeding pipes 41 to avoid agglomeration of nano-titanium dioxide and nano-silica before mixing. Then, it is connected to the mixer 5 through the jet pump 55. The jet pump 55 generates high-pressure air flow to entrain the materials and introduce them into the dispersion adder 54. During the mixing process of the liquid-phase materials by the mixer 5, the solid-phase materials are evenly dispersed and added to the liquid-phase materials by the mixer 5 in cooperation with the dispersion adder 54, thus achieving the purpose of uniform mixing;

[0062] Furthermore, according to the attached Figure 1 - attached Figure 4It can be seen that the above-mentioned power device 3 can drive the premixing batcher 7, the liquid material pre-mixer 81 and the mixing device 5 to operate simultaneously. This not only facilitates the power management of the equipment, optimizes the spatial layout of the equipment, but also can save the energy waste of the power device 3 and facilitate the maintenance of the power device 3;

[0063] According to the attached Figure 1 - attached Figure 5 It can be seen that the mixing kettle body 2 is the main container for mixing. Specifically, the mixing kettle body 2 is a hollow shell with a cylindrical structure. The mixing kettle body 2 is welded to the main support 11 or fixed by bolts. The mixing kettle body 2 adopts a horizontal structure. A discharge port 21 is arranged on one side of the bottom of the mixing kettle body 2. The mixed coating is discharged through the discharge port 21 on one side of the mixing kettle body 2. The discharge port 21 is controlled by a valve. Furthermore, a fixed seat 22 is arranged on one side of the mixing kettle body 2 to fixedly support the dispersion adder 54. On the one hand, it ensures that during the operation of the mixing device 5, it will not affect the stable feeding of the dispersion adder 54. On the other hand, the fixed seat 22 can play a role in externally wrapping and limiting the dispersion adder 54, and the dispersion adder 54 is used to further limit the mixing main shaft 51 to ensure the stable operation of the mixing main shaft 51. And a rotating shaft seat 23 is arranged at the other end of the mixing kettle body 2, and the rotating shaft seat 23 supports and limits the mixing main shaft 51;

[0064] According to the attached Figure 1 - attached Figure 5 It can be seen that the above-mentioned mixing device 5 is composed of a mixing main shaft 51 connected to the power device 3, a pair of fixed bearings 52 for installing both ends of the mixing main shaft 51, a plurality of mixing augers 53 sleeved outside the mixing main shaft 51, and a dispersion adder 54 arranged along the axial direction of the mixing main shaft 51 and connected to the injection pump 55. In the specific implementation process, the power device 3 drives the mixing main shaft 51 in a linkage manner, so that the mixing main shaft 51 drives a plurality of mixing augers 53 to rotate. The materials entering the mixing kettle are mixed by the mixing augers 53. Furthermore, a pair of fixed bearings 52 play a role in supporting and reducing the resistance of the mixing main shaft 51, and the dispersion adder 54 is used to achieve the dispersion addition of the materials to improve the uniformity of the solid phase mixed into the liquid phase materials;

[0065] According to the attached Figure 7 - attached Figure 8It can be seen that the above liquid material storage tank 8 is divided into a main storage tank and an auxiliary storage tank. The main storage tank contains a polymer substrate, and the auxiliary storage tank contains a solvent and other additives. The liquid material storage tank 8 is connected with a liquid inlet pipe, and a switch control valve 84 is arranged at the bottom of the liquid material storage tank 8. The polymer substrate is used as the main material of the coating. The volume of the main storage tank is larger than that of the auxiliary storage tank for the solvent and additives. The additives are various materials such as a leveling agent and a dispersant that have been pre-mixed. The materials in the liquid material storage tank 8 enter the liquid inlet pipe under the action of gravity, and the switch control valve 84 is used to control the switch of the liquid inlet pipe to add the liquid material into the liquid pre-mixer 81;

[0066] According to the attached Figure 7 It can be seen that in order to improve the dissolution effect of the additives and shorten the mixing process, a liquid pre-mixer 81 is connected to one side of the liquid inlet pipe. The liquid pre-mixer 81 is used to pre-mix all the liquid materials and additives, thereby shortening the mixing process and improving the mixing efficiency. Specifically, the liquid pre-mixer 81 includes a pre-mixing shaft 812, the pre-mixing shaft 812 is assembled in the pre-mixing pipe shell 811, a number of mixing blades 813 are arranged on the pre-mixing shaft 812, and a secondary shaft seat is arranged at the shaft end of the pre-mixing shaft 812. The secondary shaft seat is connected to an output end of the gearbox 32;

[0067] In the specific implementation process, the secondary shaft seat at the shaft end of the pre-mixing shaft 812 is connected to the gearbox 32. The gearbox 32 drives the pre-mixing shaft 812 to rotate, so that the pre-mixing shaft 812 drives the mixing blades 813 to rotate, and further the mixing blades 813 stir the liquid-phase materials passing through the pre-mixing pipe shell 811 to complete the pre-mixing of the liquid materials. The pre-mixed liquid-phase materials enter the liquid material equalizing inlet 82.

[0068] According to the attached Figure 1 - attached Figure 4 and attached Figure 8 It can be seen that a liquid material equalizing inlet 82 is arranged at the top of the mixing kettle body 2. The liquid material equalizing inlet 82 can disperse the liquid-phase materials, so that the liquid-phase materials are more uniform when entering the mixing kettle body 2. The liquid material equalizing inlet 82 includes a shunt housing 821. A number of shunt pipes 822 are arranged at the bottom of the shunt housing 821 and penetrate through the top of the mixing kettle body 2. The shunt housing 821 is connected to the pre-mixing pipe shell 811. The pre-mixed liquid material is shunted after entering the shunt housing 821 and is pumped into the mixing kettle body 2 through a number of shunt pipes 822. A pressure valve is arranged on the shunt pipes 822. When there is enough liquid material, the shunt pipes 822 will open, which also plays a role in preventing the material from flowing back. The feeding of the liquid material is monitored by a flow meter 83. The top of the pre-mixing pipe shell 811 is connected with a backwashing head 823. The backwashing head 823 is connected to an external pipeline by a three-way valve structure and can clean the liquid inlet pipe and the mixing kettle body 2.

[0069] According to the attachedFigure 1 - Attachment Figure 4 and attachment Figure 9 and attachment Figure 11 It can be seen that the power device 3 is jointly composed of a power motor 31 and a gearbox 32. The gearbox 32 has at least a pair of output ends respectively connected to the premixing batching device 7 and the liquid material pre-mixer 81. The power motor 31 is decelerated and power-shunted through the gearbox 32. On the basis of ensuring the rotation speed of the mixing main shaft 51, the torque requirement for the motor is reduced. At the same time, through the shunting effect of the gearbox 32, the premixing batching device 7 and the liquid material pre-mixer 81 can be driven to rotate synchronously. The mixing main shaft 51 is connected to the output end of the gearbox 32 through a coupling, and multiple mechanisms are synchronously driven by the gearbox 32, achieving the purpose of saving power.

[0070] According to the attachment in the specification Figure 1 - Attachment Figure 4 and attachment Figure 10 It can be seen that the above-mentioned premixing batching device 7 includes a premixing housing 71. A premixing auger 72 is assembled in the premixing housing 71. The premixing auger 72 is a pair of symmetric screw augers. A stirrer 73 is arranged on the premixing auger 72 corresponding to the feed pipe 41 of the mixing batching tank 4. A pair of output splines 74 are arranged at the end of the premixing auger 72 and connected to the output end of the gearbox 32. An outlet 75 is arranged at the end of the premixing housing 71;

[0071] The premixing housing 71 is communicated with the feed pipe 41. Through the meshing action of the premixing housing 71 and the premixing auger 72, the solid-phase material is pushed forward. The solid-phase material falls into the premixing housing 71 through the feed pipe 41. At the corresponding position of the premixing auger 72, the solid-phase material is fully mixed by the stirrer 73 and travels toward the outlet 75 under the action of the premixing auger 72. Then, the outlet 75 is connected to the dispersion adding device 54, and the solid-phase material travels toward the dispersion adding device 54 under the push of the outlet 75. The premixing housing 71 is a cavity housing with an oblong cross-section. An inlet is arranged at the top of the premixing housing 71 corresponding to the feed pipe 41. The feed pipe 41 and the inlet are connected by a threaded joint, which is convenient for disassembly and removal of the connection between the feed pipe 41 and the premixing housing 71.

[0072] The dispersion adding device 54 includes a fixed insertion tube 541. The fixed insertion tube 541 is connected to the outlet of the injection pump 55. The fixed insertion tube 541 is inserted into the mixing main shaft 51 from one end of the mixing batching tank 4. A number of dispersion nozzles 542 are arranged in an annular array on the mixing main shaft 51, and the number of dispersion nozzles 542 is communicated with the inner cavity of the mixing main shaft 51;

[0073] In the specific implementation process, the fixed insertion tube 541 is connected to the outlet of the jet pump 55, so that the solid-phase material enters the fixed insertion tube 541 under the pushing action of the high-pressure air flow. The fixed insertion tube 541 is inserted into the mixing main shaft 51. A number of dispersion nozzles 542 arranged in a ring array on the mixing main shaft 51 have the valves at the head ends opened under the action of centrifugal force. The dispersion nozzles 542 are rods of different lengths, which can assist in the mixing of the nano-scale energy-saving coating. The high-pressure jet flow generated by the jet pump 55 carries the material and sprays it into the mixing kettle body 2 from the dispersion nozzles 542. Then, the material mixed by the premixing batcher 7 forms bubbles under the action of the dispersion nozzles 542. The powder of the solid-phase material wrapped in the bubbles is crushed by the extrusion of the liquid material, increasing the shearing force of the mixing and making the mixing more uniform.

[0074] According to the attached drawings of the specification Figure 12 It can be seen that a disperser structure 9 is provided at the tail end of the mixer 5, and the disperser structure 9 penetrates into the mixing main shaft 51;

[0075] Specifically, the above-mentioned disperser structure 9 includes a head-end fixed rod 91. The head-end fixed rod 91 is assembled at the end of the mixer 5. A sealing end seat 92 is provided at the end of the head-end fixed rod 91. A number of dispersion rods 93 are arranged in a ring array on the sealing end seat 92. The number of dispersion rods 93 disperse the solid-phase material entering the mixing main shaft 51, so that the solid-phase material is evenly dispersed from the dispersion feeder 54 to avoid caking;

[0076] In the specific implementation process, the head-end fixed rod 91 is fixedly connected to the power device 3. Further, the head-end fixed rod 91 keeps the position of the sealing end seat 92 unchanged. When the solid-phase material enters the mixing main shaft 51 under the pumping action, the mixing main shaft 51 rotates under the drive of the power device, and the solid-phase material impacts the dispersion rods 93 as the mixing main shaft 51 rotates. The dispersion rods 93 are dispersedly arranged. The solid-phase material disperses the agglomerated material under the action of the dispersion rods 93, which is convenient for spraying from the nozzles 542;

[0077] According to the attached drawings of the specification Figure 13 It can be seen that the above-mentioned disperser structure 9 further includes a high-pressure flushing and carrying device 94. The high-pressure flushing and carrying device includes a high-pressure inlet pipe 941. The high-pressure inlet pipe is inserted into the head-end fixed rod 91. A number of high-pressure spray holes 942 are arranged in a ring on the sealing end seat 92. The number of high-pressure spray holes 942 is communicated with the high-pressure inlet pipe 941. One side of the high-pressure inlet pipe 941 is connected to a high-pressure air pump. Under the action of the high-pressure air pump, the high-pressure inlet pipe 941 pumps high-pressure air into the mixing main shaft 51, and it is dispersed through the high-pressure spray holes 942, so that the pressure in the mixing main shaft 51 is evenly distributed. After the dispersion rods 93 disperse the solid-phase material, the material is in a suspended and dispersed state. Under the high pressure, the material is sprayed out from the nozzles 542. The high-pressure flushing and carrying device 94 serves the purpose of making the material dispersion more uniform and balancing the internal pressure of the mixing main shaft 51.

[0078] The discharge port 21 protrudes integrally from the mixing kettle body 2, and a shunt connecting pipe is also connected to the discharge port 21. There are not less than one blanking joint on the shunt connecting pipe. Different pipelines can be connected through the blanking joint, facilitating filling through multiple channels. The shunt connecting pipe is communicated with the discharge port 21 to achieve the shunt function.
