Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of powder coating production, in particular to a water cooling device used for powder coating production. Background Art
[0002] Powder coatings are solid-state coatings made from resins, pigments, and other raw materials. Cooling is often required during the reaction synthesis process because the reaction releases a large amount of heat, causing the system temperature to rise rapidly. Failure to cool the system can lead to runaway reactions, such as increased side reactions and unstable product properties. Therefore, water-cooling equipment is necessary for cooling.
[0003] Existing water-cooling equipment mostly uses low-temperature water for direct cooling and cannot gradually adjust the temperature. For some thermosetting powder coatings, such as polyester-epoxy powder coatings, direct cooling with low-temperature water during the curing process will cause abnormal reactions due to the sudden drop in temperature. The curing reaction requires a specific time and temperature. Sudden cooling interrupts the cross-linking reaction between the resin and the curing agent, leaving active groups, resulting in incomplete curing, which in turn affects the coating's hardness, adhesion and other properties, resulting in the coating becoming soft and reducing chemical resistance and wear resistance. Utility Model Content
[0004] In view of the above problems, the utility model provides a water cooling device for powder coating production.
[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0022] The technical solution of the present utility model is described below with reference to the accompanying drawings and embodiments.
[0023] like Figure 1-5The utility model discloses a water-cooling and cooling device for powder coating production, comprising a reactor 1, which is made of stainless steel. The surface of the reactor 1 is provided with a ceramic fiber insulation material. When the temperature of the heat-conducting oil in the cavity 15 of the reactor 1 made of stainless steel changes, the temperature of the reactor 1 will change together, thereby adjusting the temperature of the powder coating inside the reactor 1. The ceramic fiber insulation material can reduce the influence of the external environment on the temperature change of the reactor 1. A mixing box 2 is provided on the right side of the reactor 1, and a mixing valve 5 is fixedly provided on the top of the mixing box 2. A cold water component is provided at one water inlet end of the mixing valve 5, and a water storage component is provided at the rear side of the mixing box 2. The water outlet end of the mixing valve 5 passes through the mixing box 2 and extends to the interior of the mixing box 2 and is fixedly provided with a water outlet pipe 6. A stirring component is provided inside the mixing box 2. A cavity 15 is opened inside the reactor 1, and a heat exchange water pipe 8 is fixedly provided inside the cavity 15. A circulating water pipe 7 is fixedly provided at the water outlet end of the heat exchange water pipe 8 , a water delivery component is provided on the rear side of the mixing box 2, and the mixing box 2 is fixedly connected to the water inlet end of the heat exchange water pipe 8 through the water delivery component, and a temperature sensor 14 is fixedly provided inside the mixing box 2. The water cooling and cooling equipment for powder coating production first adds a certain amount of warm water into the mixing box 2, and delivers the low-temperature water to the mixing valve 5 through the cold water component. The mixing valve 5 delivers the low-temperature water into the mixing box 2 through the outlet pipe 6, so that the low-temperature water and the warm water in the mixing box 2 are stirred and mixed, and the water temperature inside the mixing box 2 is detected and monitored by the temperature sensor 14, and the mixed water is delivered to the heat exchange water pipe 8 through the water delivery component, and the heat transfer oil inside the cavity 15 is cooled by the heat exchange water pipe 8, and then the heat transfer oil cools the reactor 1 and the powder coating inside the reactor 1. The device avoids cooling the powder coating processing process by low-temperature water at the beginning, thereby avoiding abnormal reaction of the powder coating caused by sudden cooling, and improving the processing quality of the powder coating.
[0024] Specifically, the cold water assembly includes a cold water pipe 4 fixedly arranged at the water inlet end of the mixing valve 5, a chiller 3 is arranged on the right side of the mixing box 2, the water outlet end of the chiller 3 and the water inlet end of the cold water pipe 4 are fixedly connected, and the cold water is transported to the mixing valve 5 through the cold water pipe 4 by the chiller 3.
[0025] Specifically, the stirring assembly includes a motor 11 fixedly arranged at the bottom of the mixing box 2. The output end of the motor 11 passes through the mixing box 2 and extends to the interior of the mixing box 2 and is fixedly provided with a support shaft 12. The surface of the support shaft 12 is fixedly provided with a stirring blade 13. There are multiple stirring blades 13, and the multiple stirring blades 13 are distributed in a linear array. Starting the motor 11 causes the support shaft 12 to rotate. The rotation of the support shaft 12 drives the stirring blades 13 to rotate. The rotation of the stirring blades 13 causes the low-temperature water and the warm water in the mixing box 2 to be stirred and mixed, thereby accelerating the mixing speed.
[0026] Specifically, the water delivery component includes a first water pump 10 fixedly arranged on the rear side of the mixing box 2. The water inlet end of the first water pump 10 passes through the mixing box 2 and extends to the interior of the mixing box 2. The water outlet end of the first water pump 10 is fixedly provided with a delivery water pipe 9. The water outlet end of the delivery water pipe 9 and the water inlet end of the heat exchange water pipe 8 are fixedly connected. When the first water pump 10 is started, the water inside the mixing box 2 is pumped out and delivered to the interior of the heat exchange water pipe 8 through the delivery water pipe 9, so as to deliver the water inside the mixing box 2 and the mixed water to the interior of the heat exchange water pipe 8.
[0027] Specifically, the water storage assembly includes a water tank 16 fixedly arranged on the rear side of the mixing box 2, and a second water pump 17 is fixedly arranged on the front side of the water tank 16. The water inlet end of the second water pump 17 passes through the water tank 16 and extends to the interior of the water tank 16. The water outlet end of the second water pump 17 is fixedly provided with a connecting water pipe 18. The water inlet end of the connecting water pipe 18 is fixedly connected to the water inlet end of the mixing valve 5, and the water inlet end of the water tank 16 is fixedly connected to the water outlet end of the circulating water pipe 7. The heated cooling water can be stored through the water tank 16, and then the heated cooling water can be transported to the mixing valve 5 through the second water pump 17 and the connecting water pipe 18.
[0028] It can be explained here that the mixing valve 5 changes the valve core position according to its internal regulating device to control the opening of the two water inlet ends, thereby accurately adjusting the proportion of water flows of different temperatures or components to achieve mixing and flow control. The mixing valve 5 is a conventional existing technology, so it will not be explained later.
[0029] The working principle of the utility model is as follows: the cavity 15 in the reactor 1 is filled with heat-conducting oil, and a certain amount of warm water is added to the mixing box 2. When water cooling is required, low-temperature water is produced by the chiller 3, and the low-temperature water is transported to the mixing valve 5 through the cold water pipe 4. The mixing valve 5 sends the low-temperature water into the mixing box 2 through the outlet pipe 6, and the motor 11 is started to rotate the support shaft 12. The rotation of the support shaft 12 drives the stirring blade 13 to rotate and mix the low-temperature water and the warm water in the mixing box 2. The water temperature in the mixing box 2 is detected and monitored by the temperature sensor 14. The first water pump 10 is started to mix the water in the mixing box 2. The heat transfer oil is extracted and transported to the inside of the heat exchange water pipe 8 through the delivery water pipe 9. The heat exchange water pipe 8 cools the heat transfer oil, and the heat transfer oil cools the reactor 1 and the powder coating inside the reactor 1. Then the heat exchange water pipe 8 transports the heated water to the inside of the water storage tank 16 through the circulating water pipe 7. The second water pump 17 is started to transport the water inside the water storage tank 16 to the inside of the mixing valve 5 through the connecting water pipe 18. The mixing valve 5 then transports the water back to the inside of the mixing box 2 to mix with the new low-temperature water. By adjusting the mixing valve 5, the ratio of water entering the two water inlets can be controlled, thereby gradually reducing the temperature of the mixed water inside the mixing box 2.
