Description

Technical Field

[0001] This utility model relates to the field of radiation-cooled coating preparation technology, and in particular to a radiation-cooled coating dispersion device. Background Technology

[0002] Radiation-cooling coatings are a new type of coating with special functions. During the preparation process, various nanoscale functional fillers need to be uniformly dispersed in the base material. They achieve a passive cooling effect by selectively radiating infrared heat. They have broad application prospects in fields such as building energy conservation and heat dissipation of electronic equipment.

[0003] Traditional dispersion equipment typically employs simple mechanical stirring, which makes it difficult to achieve uniform dispersion of nano-sized fillers. Furthermore, the high shear force under mechanical stirring can easily lead to an increase in coating temperature. Radiative cooling coatings are quite sensitive to temperature, and the increased temperature can easily affect coating performance. Although ultrasonic-assisted dispersion technology can improve the dispersion effect, its energy utilization rate is low when used alone.

[0004] Therefore, to address the above problems, a radiation-cooled coating dispersion device can be designed. This device primarily uses mechanical stirring, supplemented by ultrasonic-assisted dispersion, to achieve uniform dispersion of the filler. A cooling device is also added around the dispersion tank to maintain a stable coating temperature and prevent any impact on the coating's performance. Utility Model Content

[0005] Traditional dispersion equipment typically employs simple mechanical stirring, which makes it difficult to achieve uniform dispersion of nano-sized fillers. Furthermore, the high shear force of mechanical stirring can easily lead to an increase in coating temperature. Radiative cooling coatings are highly sensitive to temperature, and the increased temperature can easily affect coating performance. While ultrasonic-assisted dispersion technology can improve the dispersion effect, it suffers from low energy utilization when used alone.

[0006] The technical solution of this utility model is as follows: a radiation-cooled coating dispersion device, comprising a dispersion tank, a tank cover, a cooling jacket, an ultrasonic vibrating rod, a stirring assembly, and a cleaning assembly. The tank cover is disposed at the upper end of the dispersion tank, the cooling jacket is fixedly sleeved on the periphery of the dispersion tank, the stirring assembly is disposed inside the dispersion tank, the ultrasonic vibrating rod is fixedly installed on one side of the dispersion tank, the output end of the ultrasonic vibrating rod is located below the stirring assembly, and the cleaning assembly is disposed on the periphery of the tank cover.

[0007] Preferably, the coating in the dispersion tank can be stirred by setting a stirring component, and microwaves can be generated by the ultrasonic vibrator in the coating. This, together with the stirring component, improves the dispersion uniformity of the filler in the radiative cooling coating. It can also solve the problem of low energy utilization when using ultrasonic vibration alone for dispersion. The ultrasonic vibrator is located below the stirring component. When the material is discharged after dispersion, the high-frequency vibration of the ultrasonic vibrator can also prevent the coating from accumulating and clogging during discharge. The cooling jacket can absorb the heat generated under the high shear force of mechanical stirring, so that the coating temperature remains stable and prevents it from affecting the performance of the coating. The cleaning component can be used to rinse and clean the inside of the dispersion tank.

[0008] Preferably, a discharge pipe is connected to the lower end of the dispersion tank, and a control valve is installed at the connection between the discharge pipe and the dispersion tank.

[0009] Preferably, the upper end of the bucket lid is connected to a feeding port, and a dust cover is provided at the upper end of the feeding port.

[0010] Preferably, the lower end of the cooling jacket is connected to both a water inlet pipe and a water outlet pipe.

[0011] Preferably, the stirring assembly includes a motor, a rotating shaft, and a dispersing disc. The motor is fixedly installed on the upper end of the bucket lid, the rotating shaft is fixedly installed on the output end of the motor, the rotating shaft is rotatably connected to the bucket lid, and the dispersing disc is fixedly installed on the periphery of the rotating shaft.

[0012] Preferably, the stirring assembly includes a main stirring blade and an auxiliary stirring blade. The main stirring blade is fixedly installed at a 45° angle on the periphery of the rotating shaft, and the auxiliary stirring blade is fixedly installed vertically on the periphery of the rotating shaft.

[0013] Preferably, the cleaning component includes a diversion pipe, a water inlet, and rinsing nozzles. The diversion pipe is fixedly installed at the lower end of the bucket lid, and the upper end of the diversion pipe is connected to an injection port. The lower end of the diversion pipe is circumferentially connected to multiple sets of rinsing nozzles.

[0014] The beneficial effects of this utility model are:

[0015] The mixing assembly mechanically stirs the coating in the dispersion tank, while the ultrasonic vibrator generates microwaves within the coating. This, combined with the mixing assembly, improves the uniformity of filler dispersion in the radiative cooling coating and addresses the issue of low energy utilization when using ultrasonic vibration alone for dispersion. The ultrasonic vibrator, located below the mixing assembly, vibrates at high frequency during discharge after dispersion to prevent coating buildup and blockage. Connected to an external water supply system via inlet and outlet pipes, the system provides circulating cooling water to the cooling jacket. This cooling jacket removes the heat generated by the high shear force of mechanical stirring within the dispersion tank, maintaining a stable coating temperature. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 and Figure 3This utility model provides an embodiment: a radiation-cooled coating dispersion device, including a dispersion tank 1, a tank cover 2, a cooling jacket 3, an ultrasonic vibrating rod 4, a stirring assembly, and a cleaning assembly. The tank cover 2 is disposed at the upper end of the dispersion tank 1, the cooling jacket 3 is fixedly sleeved around the outer periphery of the dispersion tank 1, the stirring assembly is disposed inside the dispersion tank 1, the ultrasonic vibrating rod 4 is fixedly installed on one side of the dispersion tank 1, and the output end of the ultrasonic vibrating rod 4 is located below the stirring assembly. The cleaning assembly is disposed around the outer periphery of the tank cover 2. By setting the stirring assembly, the coating in the dispersion tank 1 can be stirred; by setting the ultrasonic vibrating rod 4, the coating can be stirred. Microwaves are generated by vibration within the coating, which, in conjunction with the stirring assembly, improves the uniformity of filler dispersion in the radiative cooling coating. This also solves the problem of low energy utilization when using ultrasonic vibration alone for dispersion. The ultrasonic vibrator 4 is located below the stirring assembly. When discharging after dispersion, the ultrasonic vibrator 4 vibrates at high frequency to prevent coating from accumulating and clogging during discharge. The cooling jacket 3 absorbs the heat generated under the high shear force of mechanical stirring, keeping the coating temperature stable and preventing any impact on the coating's performance. The cleaning assembly allows for rinsing and cleaning of the inside of the dispersion tank 1.

[0023] Please see Figure 1 and Figure 2 In this embodiment, a discharge pipe 101 is connected to the lower end of the dispersion tank 1, and a control valve 102 is provided at the connection between the discharge pipe 101 and the dispersion tank 1. The control valve 102 can control the discharge pipe 101, thereby controlling the discharge of the coating in the dispersion tank 1. A feeding port 201 is connected to the upper end of the tank cover 2, and a dust cover 202 is provided at the upper end of the feeding port 201. Material can be added to the dispersion tank 1 through the feeding port 201, and the dust cover 202 can cover the feeding port when no material is being added to prevent debris from entering the dispersion tank 1. A water inlet pipe 301 and a drain pipe 302 are connected to the lower end of the cooling jacket 3. The water inlet pipe 301 and the drain pipe 302 can be connected to an external water supply device to supply cooling water to the inside of the cooling jacket 3, so as to remove the heat in the dispersion tank 1 in time.

[0024] Please see Figure 3 and Figure 4In this embodiment, the stirring assembly includes a motor 501, a rotating shaft 502, and a dispersing disc 503. The motor 501 is fixedly installed on the upper end of the bucket cover 2, and the rotating shaft 502 is fixedly installed on the output end of the motor 501. The rotating shaft 502 is rotatably connected to the bucket cover 2, and the dispersing disc 503 is fixedly installed around the rotating shaft 502. The stirring assembly includes a main stirring blade 504 and an auxiliary stirring blade 505. The main stirring blade 504 is fixedly installed at a 45° angle around the rotating shaft 502, and the auxiliary stirring blade 505 is vertically fixedly installed around the rotating shaft 502. The length of the main stirring blade 504 is greater than that of the auxiliary stirring blade 505. By setting the motor 501 to drive the rotating shaft 502 to rotate, the dispersing disc 503, the main stirring blade 504, and the auxiliary stirring blade 505 can be driven to rotate synchronously. By setting the dispersing disc 503, the coating can be stirred. The filler inside is dispersed, and the coating is stirred by the stirring blades, so that the filler and the base material of the coating can be fully mixed. The multi-angle and different length arrangement of the main stirring blade 504 and the auxiliary stirring blade 505 improves the stirring efficiency, reduces the formation of eddies, and makes the coating more uniformly dispersed. The cleaning component includes a diversion pipe 601, a water inlet 602, and a rinsing nozzle 603. The diversion pipe 601 is fixedly installed at the lower end of the bucket cover 2. The upper end of the diversion pipe 601 is connected to the injection port, and the lower end of the diversion pipe 601 is circumferentially connected to multiple sets of rinsing nozzles 603. The water inlet 602 can inject clean water into the inside of the diversion pipe 601, and then deliver the clean water to each rinsing nozzle 603 through the diversion pipe 601 to clean the inside of the dispersion bucket 1.

[0025] When working, materials can be added to the dispersion tank 1 through the feeding port 201. By setting the dust cover 202, the feeding port can be blocked when no materials are being added, preventing foreign matter from entering the dispersion tank 1.

[0026] The motor 501 drives the rotating shaft 502 to rotate, which in turn drives the dispersing disc 503, the main stirring blade 504 and the auxiliary stirring blade 505 to rotate synchronously, thereby mechanically stirring the coating in the dispersing tank 1 and dispersing the filler in the coating. The arrangement of the main stirring blade 504 and the auxiliary stirring blade 505 at multiple angles and of different lengths improves the stirring efficiency, reduces the formation of eddies, and makes the coating more evenly dispersed.

[0027] While stirring, the ultrasonic vibrating rod 4 can generate microwaves by vibrating inside the coating, which further improves the dispersion uniformity of fillers in the radiation cooling coating. The ultrasonic vibrating rod 4, in combination with mechanical stirring, can solve the problem of low energy utilization when using ultrasonic vibration alone for dispersion. The high-frequency vibration of the ultrasonic vibrating rod 4 during discharge can also prevent the coating from accumulating and clogging during discharge.

[0028] By connecting the inlet pipe 301 and the drain pipe 302 to the external water supply system, circulating cooling water can be provided to the cooling jacket 3, thereby removing the heat generated in the dispersion tank 1 under the high shear force of mechanical stirring, so as to keep the coating temperature stable and prevent it from affecting the performance of the coating.

[0029] When it is necessary to clean the inside of the dispersion tank 1, clean water can be injected into the inside of the diversion pipe 601 through the water inlet 602, and then the clean water is delivered to each rinsing nozzle 603 through the diversion pipe 601 to spray out and clean the inside of the dispersion tank 1.

[0030] Through the above steps, the ultrasonic vibrating rod 4 can generate microwaves within the coating, which, in conjunction with the mechanical stirring of the stirring component, can improve the uniformity of filler dispersion in the radiative cooling coating. It also solves the problem of low energy utilization when using ultrasonic vibration alone for dispersion. Furthermore, the high-frequency vibration of the ultrasonic vibrating rod 4 can prevent coating accumulation and blockage during discharge. The cooling jacket 3 absorbs the heat generated under the high shear force of mechanical stirring, keeping the coating temperature stable. This addresses the problem that traditional dispersion equipment typically uses simple mechanical stirring, which is difficult to achieve uniform dispersion of nano-sized fillers. Additionally, the high shear force of mechanical stirring easily leads to increased coating temperature, which is particularly sensitive to temperature in radiative cooling coatings, and the increased temperature can affect coating performance. While ultrasonic-assisted dispersion technology can improve the dispersion effect, its low energy utilization when used alone is a significant drawback.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention 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 the present invention.
