Description

Technical Field

[0001] The utility model relates to cooling equipment for EVA particle production, belonging to the field of EVA particle production. Background Art

[0002] In the production process of EVA particles, cooling is a crucial link. At present, there are a variety of cooling devices for EVA particle production on the market, most of which adopt traditional cooling methods, such as air cooling or water cooling. However, these existing technologies have some obvious shortcomings in practical applications.

[0003] First, the traditional air cooling method usually relies on fans or airflow devices to generate air flow, and achieves cooling through heat exchange between air and EVA particles. However, this method has the problem of uneven cooling, because the air flow often cannot fully cover all particles, resulting in insufficient cooling of some particles and overcooling of some particles, affecting product quality. Secondly, although the water cooling method has a better cooling effect, it has the problems of complex operation and high cost. Water cooling equipment needs to be equipped with corresponding water system and cooling medium, which not only increases the complexity and maintenance cost of the equipment, but may also cause quality problems due to the contact between the cooling medium and EVA particles.

[0026] A stirring assembly is provided on the right side of the cooling bin 2 to improve the cooling effect.

[0027] It should be noted that a temperature sensor 18 is fixedly connected to the inner rear side wall of the shell 6, a PID temperature controller 19 is fixedly connected to the upper surface of the shell 6, a filter screen 20 is fixedly connected to the air inlet of the air inlet pipe 8, and the filter assembly includes a filter box 21 fixedly connected to the right end of the air outlet pipe 10 and an activated carbon plate 22 fixedly connected between the inner top wall and the inner bottom wall of the filter box 21.

[0028] The bottom end of the fixed pipe 16 passes through the upper surface of the cooling bin 2 and extends to the inner side of the cooling bin 2 and is fixedly connected to the connecting port of the nozzle 17. The left end of the nozzle 17 is fixedly connected to the inner left side wall of the cooling bin 2, and the right end of the nozzle 17 is fixedly connected to the inner right side wall of the cooling bin 2.

[0029] A pipe cover 23 is hinged at the top end of the feed pipe 3, and the feed pipe 3 is located behind the nozzle 17. The stirring assembly includes a servo motor 24 fixedly connected to the right side of the cooling bin 2, a rotating rod 25 fixedly connected to the output shaft of the servo motor 24, and a stirring blade 26 fixedly connected to the outside of the rotating rod 25. The left end of the rotating rod 25 successively penetrates the right side wall of the cooling bin 2 and the center of the stirring blade 26 and is rotatably connected to the inner left side wall of the cooling bin 2.

[0030] In addition, a material taking door for taking out the cooled EVA particles is hinged on the front of the cooling bin 2.

[0031] The working principle of the above embodiment is:

[0032] The first fan 9 is started to extract the external air. When the external air is extracted, it will first pass through the filter 20 to intercept the dust and impurities carried in the gas, thereby preventing the surface of the condenser 7 from accumulating dirt and impurities, ensuring the heat dissipation effect of the condenser 7. After that, the gas enters the interior of the shell 6. When the external air passes through the condenser 7, the cooling medium absorbs the heat in the air to reduce the air temperature. In the process of cooling the air by the condenser 7, the temperature of the air is detected by the temperature sensor 18 to prevent the air temperature from being too low. When the appropriate water value is reached, the PID temperature controller 19 starts the second fan 11 to transport the cooled air to the filter box 21, and the odor in the gas is adsorbed by the activated carbon plate 22 in the filter box 21.

[0033] Subsequently, the air pump 13 is started, and the air pump 13 extracts the cold air in the filter box 21 through the suction pipe 12 and transports it through the connecting pipe 14. During the transportation process, the air volume is adjusted by the regulating valve 15. After that, the cold air is transported to the nozzle 17 through the fixed pipe 16, and the EVA particles in the cooling bin 2 are air-cooled by the nozzle 17. During the air-cooling process, the servo motor 24 is started to drive the rotating rod 25 to rotate, and the rotating rod 25 then drives the stirring blades 26 to stir the EVA particles, thereby increasing the contact area between the EVA particles and the cooling air and improving the cooling effect. At the same time, stirring can also prevent the EVA particles from accumulating during the cooling process, thereby ensuring the uniformity of cooling.

[0034] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the text.
