Description
Technical Field
[0001] This application relates to the field of powder mixing technology, and in particular to a mixing device. Background Technology
[0002] Currently, in the production of a powder material for a waterproof and mildew-proof coating for buildings, it is necessary to manually heat and stir ultrafine powder with coconut oil until it is completely mixed. During the mixing process, workers need to stir at 40°C for 20 to 30 minutes to completely mix 10 kg of ultrafine powder with coconut oil. Moreover, the mixed product may have agglomeration, so it needs to be re-dispersed to an ultrafine powder state. Only powder with a diameter of about 10 μm is considered a qualified product. However, according to the existing process, only 20 to 30% of the products are qualified after each mixing and screening. The unqualified products need to be remixed and dispersed, resulting in very low production efficiency and high labor intensity for workers. Utility Model Content

[0035] An embodiment of this application provides a mixing device, see [link to relevant documentation]. Figures 1 to 3 The system includes a pipe 100, a fan 600, and a liquid supply mechanism. The pipe 100 includes a first port 110 and a second port 130, extending from the first port 110 to the second port 130. An inlet 120 for supplying powder into the pipe 100 is provided on the side wall of the pipe 100. The fan 600 forms an airflow from the first port 110 to the second port 130. The liquid supply mechanism includes a liquid supply pipe 320 and a spraying assembly 300 connected to each other. The spraying assembly 300 is installed inside the pipe 100. The inlet 120 is located between the fan 600 and the spraying assembly 300. A mixing chamber 140 is formed between the spraying assembly 300 and the second port 130.
[0036] When in use, the powder enters the pipe 100 through the inlet. The blower disperses the powder and blows it along the direction from the first opening to the second opening of the pipe 100 towards the spraying assembly 300. The liquid supply pipe 320 supplies oil to the spraying assembly 300, which sprays the oil into the pipe 100. At this time, the mixing chamber 140 in the pipe 100 provides a mixing space for the powder and oil. The oil is sprayed onto the flowing powder. In other words, the powder and the sprayed oil are mixed in the mixing chamber 140 to obtain powder mixed with oil. This mixing device has high mixing efficiency and uniform mixing, which improves the output rate of qualified products, solves the problem of long mixing time for manual stirring and the need for repeated processing of unqualified products, and reduces the labor intensity of workers.
[0037] Reference Figures 1 to 3 In some embodiments, the spraying assembly 300 includes a plurality of electrostatic rotary cups 310 arranged along the inner circumference of the pipe 100. The discharge direction of the electrostatic rotary cups 310 is directed toward the mixing chamber 140. The electrostatic rotary cups 310 can atomize the oil and uniformly coat the oil onto the ultrafine powder, ensuring the uniformity of the mixing of the oil and the ultrafine powder, improving the powder coating efficiency. The atomization of the oil by the electrostatic rotary cups 310 can reduce oil waste and lower costs. The electrostatic rotary cups 310 provide a smoother and more uniform coating surface and are easy to operate. They are relatively simple and easy to use, making them easy for operators to master. They help to quickly complete the ultrafine powder coating process, shorten the production cycle, and reduce the volatilization of dust and solvents, which is beneficial to the health of workers.
[0038] Reference Figures 1 to 3 In some embodiments, the supply pipe 320 is provided with a pump body 330 for pumping oil to the electrostatic rotary cup 310. The pump body 330 is located outside the pipe 100 and does not occupy the internal space of the pipe 100, which facilitates the airflow of the fan 600. Specifically, the pump body 330 is a gear pump. The gear pump can precisely control the flow rate to help the electrostatic rotary cup 310 achieve more accurate oil delivery, stabilize the pressure output of the electrostatic rotary cup 310, ensure the stability of the oil supply, improve the coating quality, and effectively improve production efficiency.
[0039] A filter bag 200 is installed at the second port 130 of the pipe 100. The mixed material flows into the filter bag 200 and is collected under the airflow of the blower 600. Unmixed oil will not be collected by the filter bag 200. The filter bag 200 can effectively intercept the mixed powder particles. The filter bag 200 cannot hold oil. Unmixed oil will not be collected by the filter bag 200 and will flow out of the filter bag 200. The cost of using the filter bag 200 is relatively low. It is easy to use multiple times and easy to replace and clean. It is understood that the filter bag 200 can also use a filter screen with a particle size smaller than that of the mixed material. Unmixed oil will not be filtered by the filter screen.
[0040] exist Figure 1 In the illustrated embodiment, two electrostatic rotary cups 310 are provided, located on opposite sides of the width of the pipe 100. Under appropriate rotation speed and electrostatic voltage control, the electrostatic rotary cups 310 spray oil in the form of oil mist to mix with ultrafine powder. By setting the rotation speed and electrostatic voltage control of the electrostatic rotary cups 310, the oil spraying effect can be ensured. It is understood that the following devices can also be used instead of the electrostatic rotary cups 310, such as air spray guns (which atomize oil and spray it onto the surface of an object using compressed air); airless spray guns (which use high pressure to spray oil directly to form a fine mist), etc.
[0041] Reference Figures 1 to 3 In some embodiments, a housing 500 is provided at the second port 130 of the pipe 100, the filter bag 200 is located inside the housing 500, and the bottom of the housing 500 is provided with an outlet 510. The housing 500 collects the oil filtered from the filter bag 200 and guides the oil to the outlet 510 for discharge, so that the oil flowing out of the outlet 510 can be collected, filtered and reused, which facilitates oil recycling and effectively reduces costs.
[0042] Reference Figures 1 to 3 In some embodiments, the discharge end of the pipe 100 is provided with a first flange 160. The filter bag 200 and the housing 500 are installed on the pipe 100 through the first flange 160. The first flange 160 can ensure a tight connection between the pipe 100 and the filter bag and the housing 500, and facilitates the installation and disassembly of the filter bag, making it convenient for the maintenance and replacement of the filter bag and the pipe 100. The connection between the pipe 100 and the filter bag and the housing 500 through the first flange 160 has good sealing performance, reducing the possibility of material leakage between the pipe 100 and the filter bag. In addition, the setting of the first flange 160 can make the filter bag have strong pressure resistance and adapt to pressure changes during material conveying.
[0043] In some embodiments, the supply pipe 320 is provided with a heating device for heating the oil. The heating device is located outside the pipe 100 and does not occupy the internal space of the pipe 100. The heating device preheats the oil so that the oil can be sprayed out in the form of oil mist. The oil in this application is preferably coconut oil. The heating device needs to heat the coconut oil to 40°C.
[0044] Reference Figures 1 to 3In some embodiments, the mixing device includes a feeder 400, and a first feed hopper 150 connected to the feed inlet 120 is provided at the top of the pipe 100. The discharge end of the feeder 400 extends into the first feed hopper 150. The first feed hopper 150 allows the ultrafine powder to enter the pipe 100 through the feed inlet 120. The first feed hopper 150 can reduce material spillage and keep the working area clean. By connecting the first feed hopper 150 with the pipe 100, the efficiency of the entire mixing device's production process is improved. Specifically, the feeder 400 is a screw feeder, which can stably transport ultrafine powder.
[0045] Reference Figures 1 to 3 In some embodiments, the feed inlet of the feeder 400 is connected to a second feed hopper 410, which is located on the top of the feeder 400. The second feed hopper 410 makes it easier for materials to enter the feeder 400 and improves the feeding efficiency of the feeder 400. It allows more materials to be added at once and also helps to stabilize the feeding: ensuring the continuity and stability of the feeding, limiting material flying to a certain extent, improving the working environment, and reducing dust.
[0046] Reference Figures 1 to 3 In some embodiments, the blower 600 is installed inside the pipe 100, close to the first pipe opening 110. The pipe 100 is gradually inclined upwards from the first pipe opening 110 to the second pipe opening 130. It is understood that a flow rate control device can also be installed inside the pipe 100 to monitor the flow rate and velocity of the ultrafine powder, and to increase the wind speed of the blower 600 to precisely control the flow rate and velocity of the ultrafine powder, so as to ensure the accurate mixing ratio of ultrafine powder and oil. When the blower 600 is running, the airflow flows along the axial direction of the pipe 100, that is, the airflow generated by the blower 600 blows the powder upwards. This arrangement causes larger powder particles to settle down, which plays a role in screening and filtering impurities, so that ultrafine powder of suitable particle size enters the mixing chamber 140 under the drive of the airflow and mixes with the atomized oil.
[0047] Reference Figures 1 to 3In some embodiments, the pipe 100 includes multiple pipe units, and adjacent pipe units are connected by second flanges 170. Multiple second flanges 170 are provided. The second flanges 170 facilitate the installation and disassembly of the pipe units, allowing for rapid assembly of the pipe units to form the pipe 100 or rapid disassembly of the pipe units to disassemble the pipe 100. The second flanges 170 ensure reliable connection between pipe units, providing a robust connection and reducing the risk of leakage of ultrafine powder. Furthermore, the second flanges 170 facilitate the maintenance and replacement of the pipe 100: they allow for easy repair or replacement of individual pipe units. This configuration also offers strong scalability: it allows for flexible increases or decreases in the number of pipe units to change the length of the pipe 100.
[0048] The method of using this mixing device is as follows:
[0049] Turn on the blower 600 and adjust the power and related parameters of the blower 600 so that the powder entering the pipe 100 flows in the pipe 100 at a stable flow rate.
[0050] At the same time, the heating device is turned on to preheat the oil. After the oil is heated to a suitable temperature, it is delivered to the electrostatic rotary cup 310 through the liquid supply pipe 320. It can be understood that the rotation speed and electrostatic voltage of the electrostatic rotary cup 310 are set according to the amount of ultrafine powder and the required mixing effect.
[0051] The mixed material flows to the filter bag for collection in the direction of airflow from the blower 600, while the unmixed oil is returned to the filter through the outlet 510.
[0052] This mixing device can greatly improve production efficiency. It takes 20 to 30 minutes to mix 10 kg of ultrafine powder manually, while this mixing device can complete the mixing of 10 kg of powder in only 5 minutes. It avoids the problems of uneven mixing and incomplete dispersion by manual mixing, and reduces the labor intensity of workers and reduces manual operation steps.
[0053] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
