DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0027] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.
[0028] The present application will be further described below with reference to the drawings and specific embodiments, but is not limited to the present application.
[0029] The portable spraying device for the penetration crystallization waterproof coating provided in the present application, with reference to Figure 1 , comprises a material storage tank 4, an air storage tank 3 is arranged inside the material storage tank 4; one end of the material storage tank 4 is connected with a hand pressurizer 1 through an air inlet joint 2, and the material storage tank 4 is externally provided with a material delivery pipe 6 in communication with the material storage tank 4 and an air delivery pipe 7 in communication with the air storage tank 3;
[0030] A control switch 5 is connected with the material delivery pipe 6 and the air delivery pipe 7, the control switch 5 comprises two independent control units for respectively corresponding to the material delivery pipe 6 and the air delivery pipe 7, an upper part of the control switch 5 is provided with a controller for controlling the air delivery pipe 7, and a lower part of the control switch 5 is provided with a controller for controlling the material delivery pipe 6;
[0031] An air distribution pipe is connected with the air delivery pipe 7 at one end and connected with the material delivery pipe 6 at the other end, for introducing the gas in the air delivery pipe 7 into the material delivery pipe 6;
[0032] A spiral material distributor 9 is connected with an air distributor 8 at one end and connected with an air-material mixer 10 at the other end; and
[0033] The air-material mixer 10 is connected with the air delivery pipe 7 and the spiral material distributor 9, for mixing compressed gas and slurry, and the dispersed slurry is sprayed to a working surface under the action of the gas.
[0034] Specifically, the storage tank 4 is configured with a gas storage tank 3, and the storage tank 4 is connected to the manual pressurizer 1 through the gas inlet joint 2. This design allows the gas to be pumped into the storage tank 4 by manual pressurization, forming an internal and external pressure difference, and then pushing the slurry through the delivery pipe 6 into the spraying process. The presence of the gas storage tank 3 not only provides stable gas pressure, but also stores additional gas for subsequent use, ensuring continuous spraying operation. The storage tank 4 is configured with a gas storage tank 3, and the storage tank 4 is connected to the manual pressurizer 1 through the gas inlet joint 2. This design allows the gas to be pumped into the storage tank 4 by manual pressurization, forming an internal and external pressure difference, and then pushing the slurry through the delivery pipe 6 into the spraying process. The presence of the gas storage tank 3 not only provides stable gas pressure, but also stores additional gas for subsequent use, ensuring continuous spraying operation. The delivery pipe 6 and the gas pipe 7 are controlled by the control switch 5, and the design of the control switch 5 allows it to control the delivery pipe 6 and the gas pipe 7 simultaneously, or to control them independently. This design improves the flexibility and convenience of operation, allowing the operator to choose to control the delivery pipe 6 or the gas pipe 7 according to the situation. The specific structure of the control switch 5 includes two independent control units corresponding to the delivery pipe 6 and the gas pipe 7. These two control units are designed to be operated simultaneously or independently. Above the control switch 5, there is a controller specially designed to control the gas pipe 7, and below the control switch 5, there is another controller specially designed to control the delivery pipe 6. This layout allows the operator to intuitively identify and operate the corresponding pipe. In actual use, the operator can control the delivery pipe 6 and the gas pipe 7 by rotating or pressing the corresponding control unit on the control switch 5. When both pipes need to be controlled, the operator can operate both control units simultaneously; when only one pipe needs to be controlled, the operator can selectively operate the corresponding control unit. The air distribution pipe serves as a gas transmission bridge, guiding the gas in the gas pipe 7 to the delivery pipe 6, promoting the pre-dispersion of the slurry. This process is crucial for the uniform dispersion of the slurry, as the initial dispersion of the slurry under gas pressure helps to improve the quality and uniformity of subsequent spraying. The addition of the spiral feeder 9 further refines the slurry dispersion process. Its unique spiral-shaped inverted slot design promotes the movement of the slurry along the spiral track under the push of the gas, generating shear force that effectively breaks down the agglomerated particles and reduces air bubbles, ensuring that the slurry reaches the ideal dispersion state. The gas-material mixer 10 connects the gas pipe 7 and the spiral feeder 9, and contains specific structures (such as mixing blades and baffles) inside, which can promote the deep mixing of gas and slurry, forming a uniform gas-slurry mixture. These mixing structures ensure that the slurry and gas are fully integrated before spraying, providing high-quality raw material preparation for the final spraying operation. Through the above design, the utility model realizes efficient spraying, reduces paint waste, improves spraying efficiency, and ensures uniformity of the coating on the work surface.
[0035] Reference Figure 1The spiral distributor 9 is internally equipped with one or more helical inverted channels that extend along the length of the distributor, forming a dynamic, three-dimensional material transport channel. When gas is introduced into the material conveying pipe 6 through the air distributor 8 and mixed with the slurry, the slurry rotates along these helical channels under the push of the gas. This process not only promotes the further dispersion of the slurry but also enhances the mixing of the gas and the slurry, allowing the slurry to experience continuous shear force during its passage through the spiral distributor 9, thereby breaking down the inherent agglomerate structure and achieving a more uniform and delicate dispersion state.
[0036] The air distribution pipe is made of high-pressure and corrosion-resistant materials such as stainless steel, Teflon (PTFE) coating, nylon, or reinforced polymers. Stainless steel is often used to manufacture air distribution pipes due to its excellent mechanical strength, good corrosion resistance, and oxidation resistance, making it suitable for various industrial environments. Teflon (PTFE) coating has extremely low friction coefficient and excellent chemical inertness, preventing adhesion, making it an ideal choice for corrosion resistance and high temperature resistance, especially suitable for the coating industry. Nylon or reinforced polymers are lightweight and have good toughness, with a certain degree of elasticity, making them suitable as internal lining or overall material to reduce weight and improve durability.
[0037] To further enhance the accuracy and safety of control, the control switch 5 can be equipped with a locking mechanism to ensure that another pipeline is not accidentally affected during operation. In addition, the control switch 5 can also integrate a feedback mechanism such as an indicator light or display screen to provide real-time feedback of the current pipeline state, ensuring that the operator can accurately grasp the working state of the material conveying pipe 6 and the gas conveying pipe 7. The locking mechanism can automatically or manually lock the control switch 5 in a non-use state, preventing accidental start or mode switching due to accidental touch, especially when the device is in transport or storage state, which can greatly reduce the risk. In complex or dangerous working conditions, the locking function can prevent unauthorized personnel from operating the device, ensuring that only trained personnel can turn on or adjust the device, thereby avoiding potential injury accidents. When maintaining or cleaning the device, the locking mechanism ensures that the switch cannot be accidentally activated, creating a safer working environment for technicians. Real-time information provided by LED indicator lights, liquid crystal screens, or touch panels allows operators to quickly understand the running state of the device, including gas pressure, flow rate, and other key parameters, and make immediate adjustments. The integrated feedback mechanism can send alarm signals in time to alert the operator to potential problems such as low gas pressure, slurry blockage, and other abnormal conditions, allowing for early intervention to prevent equipment damage. High-end control systems even have data storage and remote monitoring functions, allowing historical data to be used for fault diagnosis, performance optimization, and predictive maintenance, improving device reliability and production efficiency
[0038] The design parameters of the helical channel of the screw distributor 9, such as pitch, screw depth, and helix angle, are carefully calculated and optimized to ensure optimal dispersion and flow characteristics. To enhance the durability and corrosion resistance of the device, the screw distributor 9 and the air-material mixer 10 can be made of high-strength plastic, stainless steel, or other suitable materials. The design of the device takes into account the ease of operation, allowing the user to disperse and mix the slurry simply by operating the hand press 1 without the need for complex settings or additional equipment. The design of the screw distributor 9 and the air-material mixer 10 facilitates easy disassembly and cleaning, ensuring long-term use and maintenance of the device. The user can regularly inspect the wear and tear of these two components and perform necessary replacements or cleanings to maintain the optimal performance of the device.
[0039] The air-material mixer 10 connects the air supply tube 7 and the screw distributor 9, designed to eject the dispersed slurry onto the work surface under the action of compressed air. The air-material mixer 10 is designed with specific structures inside, such as mixing chambers, nozzles, or mixing blades, which help to fully mix compressed air and slurry. Compressed air enters the air-material mixer 10 through the air supply tube 7, while the dispersed slurry from the screw distributor 9 also enters the air-material mixer 10. Inside the air-material mixer 10, compressed air and slurry are fully mixed in the mixing chamber to form a uniform air-slurry mixture. The mixed air-slurry mixture is ejected through the nozzle part of the air-material mixer 10 under the action of air pressure, directly acting on the work surface. The pressure and flow rate of the ejection can be controlled through the hand press 1 or the adjustment device on the air-material mixer 10 to adapt to different spraying needs and working conditions. The design parameters of the air-material mixer 10, such as the diameter, shape, and number of nozzles, are carefully calculated and optimized to ensure optimal ejection and uniformity of paint distribution. To enhance the durability and corrosion resistance of the device, the air-material mixer 10 can be made of high-strength plastic, stainless steel, or other suitable materials. The design of the device takes into account the ease of operation, allowing the user to mix and eject compressed air and slurry simply by operating the hand press 1 without the need for complex settings or additional equipment. The design of the air-material mixer 10 facilitates easy disassembly and cleaning, ensuring long-term use and maintenance of the device. The user can regularly inspect the wear and tear of the air-material mixer 10 and perform necessary replacements or cleanings to maintain the optimal performance of the device. The design of the air-material mixer 10 also takes into account the safety of operation, ensuring stability and safety when working under high pressure. By optimizing the design of the air-material mixer 10, paint waste can be reduced, spraying efficiency can be improved, and the uniformity of the coating on the work surface can be ensured.
[0040] The screw feeder 9 and the air-material mixer 10 are made of high-strength plastic or stainless steel. Compared with metal, high-strength plastics such as polycarbonate (PC) and polyamide (PA) have lower density, reducing the overall weight of the equipment, making it easier to transport and install, and are particularly suitable for portable applications that need to be moved frequently. Many high-strength plastics have excellent chemical stability and can resist the corrosion of various chemicals, including common solvents and acid-base environments, ensuring stable performance over a long period of time. Plastic materials are naturally insulating, which can reduce electrical safety hazards, especially in equipment involving many electronic components, which is particularly important. Compared with metal, high-strength plastics are easier to shape and can be quickly mass-produced through various methods such as injection molding and blow molding, reducing manufacturing costs and facilitating customized design. Stainless steel has excellent hardness and impact resistance, can withstand high working pressure and physical wear, and prolongs the service life of the equipment. Stainless steel can maintain structural integrity at high temperatures, making it suitable for environments that require high-temperature disinfection or work. The surface is smooth, easy to clean, and not prone to bacterial growth, meeting the hygiene requirements of food-grade or pharmaceutical-grade. Although the initial cost is higher than that of plastic, stainless steel has high recycling value and good sustainability, and is more economical in the long run.
[0041] The manual pressure device 1 includes a compressible handle 11 and an air pressure chamber 12 connected to the inside of the storage tank 4. By compressing the handle 11, a stable air pressure can be provided to the storage tank 4 to push the paint delivery. The operator pulls or presses the handle 11 back and forth to move the piston or diaphragm inside, creating a suction or squeezing effect. The air pressure chamber 12 is connected to the storage tank 4 as a space to transfer pressure. When the handle 11 moves, the gas in the air pressure chamber 12 is compressed or extracted, forming a positive and negative pressure alternating state. The valve system controls the direction of air flow to ensure that the compressed air only flows into the storage tank 4 in one direction and does not flow back to the manual pressure device 1.
[0042] The material delivery pipe 6 and the gas delivery pipe 7 are made of flexible materials to adapt to different operating environments and spraying requirements at different angles. For example, polyurethane (TPU), PVC (polyvinyl chloride), silicone, etc. Polyurethane (TPU) has wear resistance and flexibility, oil resistance, and strong weather resistance, and is suitable for outdoor and industrial environments. PVC (polyvinyl chloride) is cost-effective and widely used in civilian fields, but it may harden at low temperatures. Silicone has excellent chemical stability and temperature resistance, and is suitable for medical and food industries. Flexible materials allow the material delivery pipe 6 and the gas delivery pipe 7 to bend and stretch easily, making them flexible to deploy even in narrow or restricted spaces, covering hard-to-reach locations and improving construction efficiency. Soft materials can absorb vibrations and noise, reducing vibration transmission and noise pollution during equipment operation, creating a more comfortable working environment. Flexible pipes are less likely to kink or twist, and can maintain smooth material and gas flow even after long-term use, reducing the risk of material blockage. Soft pipes are easy to fold and coil, making them easy to carry and store, saving space and speeding up the conversion of work sites
[0043] The device also includes a nozzle that is detachably connected to the discharge end of the gas-material mixer 10 (such as threaded connection, etc.) for uniformly spraying the mixed slurry onto the target surface, allowing users to quickly replace the nozzle according to different operating types and improving efficiency. The nozzle is designed to adapt to different spraying requirements and spraying angles, and the nozzle's spray port has adjustable spraying modes, including fan-shaped spraying and circular spraying, to meet different construction requirements. Fan-shaped spraying is suitable for large-area painting, with a wide spray range and large coverage area, suitable for flat areas such as walls and ceilings; circular spraying has strong penetration and is suitable for detail processing, such as corners, gaps, or fine finishing of specific contour parts. In addition, the nozzle has an adjustment knob that allows users to fine-tune the width, flow rate, and atomization level of the spray pattern to adapt to different paint types and viscosities, ensuring accurate delivery of each drop of paint.
[0044] In summary, the portable spraying device for permeation crystallization waterproof coating uses a backpack to carry the storage tank 4, and a hand-operated pressure pump 1 to pump gas into the tank. Some of the gas enters the storage tank 4 directly through the pressure pump, creating an internal and external pressure difference that pushes the slurry into the material delivery pipe 6, while the other part of the gas enters the gas storage tank 3 for compression and storage. After the control switch 5 is turned on, the slurry enters the gun head position along the material delivery pipe 6, is dispersed by the gas in the air distributor 8, and is then sprayed out of the nozzle by the pressurized gas in the gas-material mixer 10 and uniformly dispersed onto the work surface. Continuous spraying is achieved by continuously adding gas manually.
[0045] The above merely describes preferred embodiments of the present application, and is not intended to limit the implementation and protection scope of the present application. For those skilled in the art, it should be understood that any equivalent substitutions and obvious changes made according to the content of the present application and drawings should be included in the protection scope of the present application.
