[0002] Masterbatch pelletizing is a plastic processing technology. Masterbatch is a mixture composed of pigments or dyes, carriers, and additives, and is usually used for coloring plastic products. Pelletizing is to cut masterbatch into particles of a certain size for convenient addition and use in the plastic processing process. There are many types of masterbatch pelletizing equipment and processes, specifically depending on the composition, particle size of the masterbatch, and requirements of plastic products. Generally speaking, a masterbatch pelletizing machine uses a rotating blade or a vibrating blade to cut the masterbatch into particles of the required size, and then conveys the particles to the plastic processing equipment by air flow or mechanical means; Masterbatch pelletizing often uses cooling water to cool the processed material before cutting. After conventional cooling water is used for a period of time, the water temperature is likely to rise, resulting in a poor cooling effect of the cooling water on the processed material due to the high water temperature.

Detailed implementation manner

[0024] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely in conjunction with the attached Figures 1-4 drawings in the embodiments of the present utility model.

[0025] Please refer to Figures 1-4, in the embodiment of the present utility model, a cooling water circulation device for color masterbatch pelletizing includes: a box body 1, which is divided into a first chamber 101, a second chamber 102 and a third chamber 103. A filter plate 2 is arranged inside the first chamber 101, a cooling pipe 3 is arranged inside the second chamber 102, a stirring group 4 is arranged inside the third chamber 103, and a cold air blower 5 is arranged outside the box body 1; A collection box 201 is embedded inside the filter plate 2. The stirring group 4 includes a motor 401, a rotating rod 402 and stirring blades 403. The motor 401 is fixedly installed on the outer surface of the box body 1, and the stirring blades 403 are arranged around the outer surface of the rotating rod 402. One end of the cooling pipe 3 is connected with a water pump 301, and the water pump 301 is located inside the third chamber 103 and is arranged in a staggered manner with the rotating rod 402; The first chamber 101 is mainly used for initially filtering the used cooling water to remove larger particle impurities and suspended matters therein, preventing these impurities from entering the subsequent cooling and circulation systems, thereby protecting the equipment and ensuring the cooling effect. The cooling pipe 3 is a key component for cooling the cooling water. By cooperating with the external cold air blower 5, the cooling pipe 3 can quickly reduce the temperature of the cooling water flowing through it. The function of the stirring group 4 is to fully mix the cooling water in the third chamber 103, ensure uniform water temperature, avoid local temperature being too high or too low affecting the cooling effect, and maintain the relative stability of the water quality. The cold air blower 5 arranged outside the box body 1 provides a cooling source for the entire cooling water circulation device. The cold air blower 5 blows cold air into the cooling pipe 3 in the second chamber 102 to accelerate the heat dissipation of the cooling water in the cooling pipe 3, thereby realizing the rapid cooling of the cooling water. The filter plate 2 is usually made of a material with a certain porosity and can effectively intercept impurities in the cooling water. By filtering the water for color masterbatch pelletizing through the filter plate 2, the impurities are left on the filter plate 2, thereby ensuring the cleanliness of the cooling water entering the subsequent chambers. The function of the collection box 201 is to collect the impurities intercepted by the filter plate 2. When the impurities enter the inside of the collection box 201 through the water flow direction, the collection box 201 is taken out for cleaning, thereby maintaining the filtering effect of the filter plate 2 and avoiding blocking the filter plate 2 due to excessive impurities;The motor 401 is the power source of the stirring group 4. Driven by the motor 401, the rotating rod 402 can drive the stirring blade 403 to rotate, realizing the stirring effect on the cooling water in the third chamber 103. The rotating rod 402 rotates driven by the motor 401, and the stirring blade 403 is circumferentially installed on the outer surface of the rotating rod 402. As the rotating rod 402 rotates, the stirring blade 403 can fully stir the cooling water in the third chamber 103 to ensure effective stirring of the cooling water and improve the mixing effect. The water pump 301 pumps the cooling water in the third chamber 103 into the cooling pipe 3. In the cooling pipe 3, the cooling water exchanges heat with the cold air sent by the cold air blower 5, thus realizing temperature reduction. The function of the water pump 301 is to pump the evenly stirred cooling water in the third chamber 103 into the cooling pipe 3 for cooling. The water pump 301 and the rotating rod 402 are arranged in a staggered manner, which can avoid mutual interference during operation, and is also convenient for installation and maintenance, making it more convenient to clean impurities in the device, simplifying the process of cleaning impurities, and effectively improving the cooling efficiency of the device.

[0026] In the embodiment of the present utility model, a card slot 202 is opened at the upper end of the filter plate 2, and the collection box 201 is embedded inside the card slot 202. The collection box 201 is movably connected to the card slot 202, and the outer surface of the collection box 201 is in a hollow shape; the card slot 202 provides a clear installation position for the collection box 201, ensuring that the collection box 201 can be accurately embedded, making the position of the collection box 201 on the filter plate 2 more stable and not easily moving or being misaligned, thus ensuring the effect of filtering and collecting impurities. The design of the card slot 202 makes the installation and disassembly of the collection box 201 more convenient and fast. When it is necessary to clean the impurities in the collection box 201, only need to take out the collection box 201 from the card slot 202 without complex operations, which greatly improves the maintenance efficiency of the device, reduces the maintenance time and cost, and effectively prevents the collection box 201 from shaking or falling off during operation. The outer surface of the collection box 201 is in a hollow shape, and the impurities in the cooling water can be more easily intercepted by the collection box 201, reducing the impurities from entering the subsequent circulation system. The hollow shape design does not hinder the flow of the cooling water, ensuring that the cooling water can smoothly pass through the filter plate 2 and enter the next chamber, enabling the collection box to filter impurities without affecting the use of the filter plate 2 and making the device more stable during use.

[0027] In the embodiment of the present utility model, limiting blocks 203 are installed at both ends of the collection box 201. The collection box 201 and the limiting blocks 203 are connected by a rotating shaft 204. The rotating shaft 204 is embedded inside the limiting blocks 203, and the rotating shaft 204 and the limiting blocks 203 are movably connected. Wherein, clamping plates 205 are fixedly installed on the outer sides of the limiting blocks 203. The bottoms of the clamping plates 205 are in contact with the upper end of the filter plate 2. A pull ring is fixedly installed at the bottom of the collection box 201. The limiting blocks 203 installed at both ends of the collection box 201 can limit the collection box 201 in the horizontal direction to prevent the collection box 201 from moving excessively in the card slot 202. When the collection box 201 is embedded in the card slot 202, the limiting blocks 203 ensure the accurate and stable position of the collection box 201 on the filter plate 2 through cooperation with the card slot 202. The collection box 201 can rotate within a certain angle range through the rotating shaft 204, which is convenient for the operator to take it out of the card slot 202 when cleaning the collection box 201. When it is necessary to clean the collection box 201, take the collection box 201 out of the inside of the card slot 202 and rotate the collection box 201 through the rotating shaft 204, so as to clean the impurities inside the collection box 201. With the pull ring, it is more convenient to flip the collection box 201. The operator can quickly clean and replace the collection box 201, thereby improving the maintenance efficiency of the entire cooling water circulation device. In actual operation, the operator can more efficiently complete the cleaning of impurities, ensure the normal operation of the device, and make it more convenient for the staff to clean the impurities.

[0028] In the embodiment of the present utility model, a guide plate 206 is fixedly installed on the inner wall of the upper end of the filter plate 2. The guide plate 206 is inclined inward, and one end of the guide plate 206 is in contact with the outside of the card slot 202. The filter plate 2 is inclined inside the first chamber 101. The guide plate 206 is inclined inward, and its function is to guide the impurities in the cooling water to flow towards the collection box 201. When the cooling water passes through the filter plate 2, the impurities will move along the inclined direction of the guide plate 206 under the drive of the water flow and finally enter the collection box 201, which can improve the collection efficiency of the impurities and ensure that most of the impurities can be effectively intercepted and collected. The existence of the guide plate 206 can make the impurities flow concentratedly towards the collection box 201, avoid the disorderly accumulation of impurities on the filter plate 2, and thus maintain the smoothness of the filter plate 2. Due to the action of gravity, the cooling water will flow downward along the inclined filter plate 2, accelerating the water flow speed and improving the filtration efficiency. At the same time, the inclined filter plate 2 can also reduce the resistance of the water flow and reduce the energy consumption of the device. When the impurities are intercepted by the filter plate 2, due to the inclination of the filter plate 2, the impurities will slide naturally towards the collection box 201 under the action of gravity, which is convenient for the collection and cleaning of the impurities, can reduce the workload of the operator, improve the maintenance efficiency of the device, promote the flow of the water flow, improve the filtration effect, facilitate the collection and cleaning of the impurities, and thus effectively improve the efficiency of the staff in cleaning the impurities.

[0029] In the embodiment of the present utility model, the output pipe of the cooling fan 5 is embedded in the second cavity 102, and the output pipe of the cooling fan 5 corresponds to the position of the cooling pipe 3. One end of the cooling pipe 3 is embedded in the first cavity 101, and the output end of the water pump 301 is located in the third cavity 103. The output pipe of the cooling fan 5 is embedded in the second cavity 102 and corresponds to the position of the cooling pipe 3. The cold air blown by the cooling fan 5 can directly act on the cooling pipe 3 to accurately cool the cooling water in the cooling pipe 3. Through this direct cooling method, the cooling efficiency can be improved to ensure that the cooling water can be quickly cooled down. One end of the cooling pipe 3 is embedded in the first cavity 101, so that the preliminarily filtered cooling water can smoothly enter the cooling pipe 3. The filter plate 2 in the first cavity 101 has removed the larger particle impurities in the cooling water, reducing the blockage and damage of the impurities to the cooling pipe 3 and extending the service life of the cooling pipe 3. The cooling water enters the cooling pipe 3 from the first cavity 101, and after being cooled, it is transported to the third cavity 103 by the water pump 301 for stirring and further treatment. During the whole process, the flow of the cooling water is smoother, reducing the water flow resistance and improving the circulation efficiency. The water pump 301 transports the cooled water to the third cavity 103. In the third cavity 103, the stirring group 4 can fully stir the cooling water to make the water temperature more uniform. The output end of the water pump 301 is located in the third cavity 103, ensuring that the cooled water can directly enter the stirring area and mix with other uncooled water, thereby improving the temperature uniformity of the entire cooling water circulation system and further cooling the cooling water.

[0030] In the embodiment of the present utility model, a bearing 404 is nested on the outer surface of one end of the rotating rod 402, and the bearing 404 is embedded in the inner wall of the third cavity 103. A submersible pump is arranged inside the third cavity 103, and the output end of the submersible pump is embedded inside the first cavity 101. The bearing 404 nested on the outer surface of one end of the rotating rod 402 plays an important role in support and rotation. The bearing 404 can reduce the frictional resistance of the rotating rod 402 during rotation, enabling the rotating rod 402 to rotate more smoothly and ensuring that the stirring blades 403 can efficiently stir the cooling water in the third cavity 103 to achieve uniform distribution of the water temperature. The submersible pump arranged inside the third cavity 103 provides power for the circulation of the cooling water. The submersible pump can pump out the cooling water in the third cavity 103 and transport it to the first cavity 101 to realize the circulating flow of the cooling water between different cavities, ensuring the normal operation of the entire cooling water circulation device and making the device more stable during use.

[0031] Working principle: First, the used cooling water enters the first chamber 101 of the box body 1. The filter plate 2 in the first chamber 101 preliminarily filters the cooling water, intercepting larger particle impurities and suspended matters therein. The guide plate 206 on the inner wall of the upper end of the filter plate 2 is inclined inward, guiding the impurities in the cooling water to move along the inclined direction under the drive of the water flow, and finally entering the collection box 201. The outer surface of the collection box 201 is in a hollow shape, facilitating the interception of impurities without hindering the flow of the cooling water. The collection box 201 is embedded in the card slot 202 at the upper end of the filter plate 2, with a stable position and convenient for installation and disassembly. The limit blocks 203 and the clamping plates 205 at both ends of the collection box 201 further ensure the accurate and stable position of the collection box 201 on the filter plate 2, preventing it from moving under the impact of the water flow or external force. When it is necessary to clean the collection box 201, the collection box 201 is pulled out from the card slot 202 for impurity cleaning. The preliminarily filtered cooling water enters the second chamber 102 from one end of the cooling pipe 3. The air cooler 5 outside the box body 1 sends cold air into the second chamber 102 through the output pipe, and the output pipe corresponds to the position of the cooling pipe 3, directly cooling the cooling water in the cooling pipe 3. The cooling water in the cooling pipe 3 exchanges heat with the cold air sent by the air cooler 5, quickly reducing the temperature. The cooled cooling water is pumped from the second chamber 102 into the third chamber 103 by the water pump 301. In the third chamber 103, the motor 401 drives the rotating rod 402 to rotate, driving the stirring blades 403 to fully stir the cooling water, ensuring uniform water temperature and avoiding the influence of local overheating or overcooling on the cooling effect. The bearing 404 on the outer surface of one end of the rotating rod 402 is embedded in the inner wall of the third chamber 103, reducing the frictional resistance when the rotating rod 402 rotates and improving the rotation stability and accuracy. At the same time, the submersible pump in the third chamber 103 pumps the cooling water back to the first chamber 101, realizing the recycling of the cooling water. During the whole process, the cooling water undergoes filtration, cooling, stirring, and circulation in sequence, continuously providing cooling water with a stable temperature for the masterbatch pelletizing, ensuring the smooth progress of the masterbatch pelletizing process.
