[0024] Example 1

[0025] As attached Figures 1 to 4The device shown is a premixing apparatus for UV monomer production, comprising a mixing tank 1, a water transfer tank 6, a recovery filter tank 10, and a mounting bracket 11. The mixing tank 1 serves as the tank for UV monomer premixing. A heating plate 2 is embedded in the side wall of the inner cavity of the mixing tank 1. The heating plate 2 can heat the material inside the tank. By controlling the temperature of the heating plate 2, the viscosity of the material can be adjusted, so that the material has better fluidity at a suitable temperature, thereby improving the uniformity and efficiency of mixing. A feed inlet 3 is opened at the upper right end of the mixing tank 1. The feed inlet 3 allows various raw materials to be added to the mixing tank 1 in a certain proportion and order. A load-bearing frame 4 is provided at the upper end of the mixing tank 1, providing stable support for the water transfer tank 6. The presence of the load-bearing frame 4 ensures the installation firmness of the water transfer tank 6. A waste liquid discharge port 5 is opened on the left side of the bottom of the mixing tank 1. Waste liquid discharge port 5 discharges the waste liquid in the tank in a timely manner according to the control system when cleaning the mixing tank 1, thereby improving the discharge efficiency. The water transfer tank 6 is set at the upper end of the load-bearing frame 4. The water transfer tank 6 serves as a storage and transfer container for the cleaning liquid, providing sufficient cleaning liquid for the cleaning of the mixing tank 1. A first water pump 7 is installed on the right side of the water transfer tank 6. The first water pump 7 is responsible for transporting the cleaning liquid in the water transfer tank 6 to the mixing tank 1. The use of the first water pump 7 can provide sufficient pressure to ensure that the cleaning liquid can pass smoothly through the infusion pipe 8 and the cleaning nozzle 9, thereby achieving effective cleaning of the mixing tank 1. The infusion pipe 8 is fixedly connected to the upper end of the inner cavity of the mixing tank 1. A cleaning nozzle 9 is installed at the bottom of the infusion pipe 8. The cleaning nozzle 9 sprays the cleaning liquid at a certain pressure and angle onto the inner wall and internal components of the mixing tank 1 at the bottom of the infusion pipe 8.

[0026] The recovery filter tank 10 is located below the mixing tank 1. The recovery filter tank 10 collects the waste liquid discharged from the mixing tank 1 and flows naturally into the recovery filter tank 10. The mounting bracket 11 is installed at the upper end of the inner cavity of the recovery filter tank 10. The mounting bracket 11 provides a platform for the installation and fixing of the filter plate 12. Its design makes the installation and disassembly of the filter plate 12 more convenient, and facilitates the cleaning, replacement or maintenance of the filter plate 12. The filter plate 12 is installed in the inner cavity at the bottom of the mounting bracket 11. The filter plate 12 effectively removes various residual dirt in the waste liquid, purifies the cleaning liquid, and realizes recycling. A circular handle 13 is fixedly connected to the upper edge of the mounting bracket 11. The circular handle 13 allows the operator to install or remove the mounting bracket 11 by holding the circular handle 13, thereby operating the filter plate 12.

[0027] A liquid extraction pipe 101 is provided at the bottom left side of the recovery filter tank 10. The liquid extraction pipe 101 extracts the filtered cleaning liquid. A second water pump 14 is provided on the left side of the liquid extraction pipe 101. The second water pump 14 transports the filtered cleaning liquid in the recovery filter tank 10 back to the water transfer tank 6 through the liquid delivery pipe 15, realizing the recycling of the cleaning liquid. The output end of the second water pump 14 is equipped with the liquid delivery pipe 15, which transports the filtered cleaning liquid back to the water transfer tank 6, ensuring the integrity of the cleaning liquid circulation system.

[0028] Example 2

[0029] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0030] In a preferred embodiment, the mounting bracket 11 is inserted into and abuts against the upper edge of the recovery filter tank 10. This insertion and abutment method allows operators to easily place the mounting bracket 11 into the designated position of the recovery filter tank 10. When cleaning, replacing, or inspecting the interior of the recovery filter tank 10 is required, the mounting bracket 11 can simply be pulled out of the recovery filter tank 10, which is convenient and quick. The core of the filter plate 12 contains a mixture of quartz sand and activated carbon particles with a particle size of 0.4-1.1 mm. The quartz sand primarily functions as a physical filter, intercepting larger particulate impurities in the waste liquid. Activated carbon has a strong adsorption capacity, adsorbing organic matter, pigments, odors, and some small pollutants in the waste liquid. The 0.4-1.1 mm particle size of the quartz sand and activated carbon particles is moderate, ensuring a certain filtration accuracy and effectively intercepting small impurities, while avoiding excessively small particle sizes that would lead to slow filtration speeds or easy clogging. The combined use of these two materials allows for more comprehensive removal of various impurities from the waste liquid, improving the filtration effect.

[0031] In a preferred embodiment, the input end of the first water pump 7 is connected to the water transfer tank 6, and the output end of the first water pump 7 is connected to the infusion pipe 8. The first water pump 7 can generate sufficient pressure to push the cleaning fluid in the water transfer tank 6 to overcome factors such as pipeline resistance and gravity, and smoothly reach the mixing tank 1. Connecting the first water pump 7 to the water transfer tank 6 can ensure that the cleaning fluid can be delivered from the water storage device to the mixing tank 1 in a timely manner during the cleaning process, and can ensure a sufficient supply of cleaning fluid when the mixing tank 1 is continuously cleaned or cleaned multiple times.

[0032] In a preferred embodiment, the cleaning nozzles 9 are provided in several groups, and the several groups of cleaning nozzles 9 are distributed at equal intervals. The equally distributed cleaning nozzles 9 can make the cleaning liquid evenly sprayed in the internal space of the mixing tank 1, and can ensure that all parts of the mixing tank 1 can receive the same amount of cleaning liquid.

[0033] In a preferred embodiment, the second water pump 14 is connected to the output end of the extraction pipe 101, and the end of the extraction pipe 101 away from the second water pump 14 is connected to the water transfer tank 6. The second water pump 14 enables the filtered cleaning liquid to overcome factors such as pipeline resistance and gravity, and smoothly transport it back to the water transfer tank 6 through the extraction pipe 101 and the delivery pipe 15, thereby realizing the recycling of the cleaning liquid and reducing production costs and water consumption.

[0034] In a preferred embodiment, a drain valve 19 is provided at the bottom right side of the mixing tank 1. During the production process, the drain valve 19 discharges the UV monomer mixture in the mixing tank 1 smoothly under the control of the control system. The pipe of the waste liquid discharge port 5, which is away from the mixing tank 1, extends to the top of the mounting bracket 11. The waste liquid discharge port 5 can accurately guide the waste liquid used for cleaning in the mixing tank 1 to the recycling filter tank 10.

[0035] In a preferred embodiment, a transmission rod 16 is installed at the center of the inner cavity of the mixing tank 1, and a motor 18 is installed at the center of the upper end of the mixing tank 1. The rod body of the transmission rod 16 is fixedly connected to a stirring blade 17. There are three sets of stirring blades 17. The motor 18 drives the transmission rod 16 and the stirring blades 17 to stir and mix in the mixing tank 1, and can also be used with cleaning liquid for cleaning.

[0036] In a preferred embodiment, a liquid level sensor 61 is installed on the right side of the inner cavity of the water transfer tank 6, and a water inlet valve 62 is opened at the upper end of the water transfer tank 6. The liquid level sensor 61 can monitor the water level in the water transfer tank 6 in real time. By transmitting the water level information to the control system, the control system controls the opening and closing of the water inlet valve 62 through a preset threshold, thereby controlling the flow rate of the cleaning fluid transported by the external water pipe.

[0037] The working process of this utility model is as follows: First, various raw materials are added to the mixing tank 1 through the feed port 3 in a certain proportion and order. The heating plate 2 on the inner wall of the mixing tank 1 heats the material and adjusts the viscosity of the material to make the material have better fluidity. At the same time, the motor 18 drives the transmission rod 16 and the stirring blade 17 to stir and mix the material, improve the uniformity and efficiency of mixing. There are three sets of stirring blades 17, which can stir the material more thoroughly. During the production process, according to the control of the control system, the drain valve 19 at the bottom right side of the mixing tank 1 is opened to smoothly discharge the UV monomer mixture in the mixing tank 1 for subsequent production steps.

[0038] The water transfer tank 6 serves as a storage and transfer container for the cleaning fluid. The cleaning fluid is replenished through the water inlet valve 62. The level sensor 61 monitors the water level in the water transfer tank 6 in real time and transmits the water level information to the control system. The control system controls the opening and closing of the water inlet valve 62 according to the preset threshold, thereby controlling the flow rate of the cleaning fluid delivered by the external water pipe. When cleaning is required, the first water pump 7 extracts the cleaning fluid from the water transfer tank 6 and delivers it to the mixing tank 1 through the delivery pipe 8. The sufficient pressure generated by the first water pump 7 ensures that the cleaning fluid can pass smoothly through the delivery pipe 8 and the cleaning nozzles 9. Several sets of equally spaced cleaning nozzles 9 are set at the bottom of the delivery pipe 8, which can make the cleaning fluid evenly sprayed in the internal space of the mixing tank 1. The transmission rod 16 and the stirring blade 17 driven by the motor 18 can work together with the cleaning fluid to perform cleaning.

[0039] Waste liquid generated during the cleaning of mixing tank 1 is discharged through waste liquid discharge port 5. A pipe extending from the end of waste liquid discharge port 5 away from mixing tank 1 reaches above mounting bracket 11, accurately guiding the waste liquid into recovery filter tank 10. Inside recovery filter tank 10, filter plates 12 on mounting bracket 11 filter the waste liquid. The core of filter plates 12 contains a mixture of quartz sand and activated carbon particles with a particle size of 0.4-1.1 mm. The quartz sand acts as a physical filter, intercepting larger particulate impurities, while the activated carbon adsorbs organic matter, pigments, odors, and minute pollutants. The combined use of both allows for more comprehensive removal of waste liquid. Impurities in the liquid are removed, purifying the cleaning solution. The user can lift the mounting bracket 11 for disassembly and assembly using the circular handle 13. The second water pump 14 is connected to the output end of the extraction pipe 101, and the end of the extraction pipe 101 away from the second water pump 14 is connected to the water transfer tank 6. The second water pump 14 transports the cleaning solution filtered in the recovery filter tank 10 back to the water transfer tank 6 through the extraction pipe 101 and the delivery pipe 15, realizing the recycling of the cleaning solution and reducing production costs and water consumption. The above is the working principle of this premixing device for UV monomer production.
