Description

Technical Field

[0001] This utility model relates to the field of control device technology, specifically a high-efficiency and energy-saving open mill temperature control device. Background Technology

[0002] A two-roll mill is a widely used piece of machinery in the processing of polymer materials such as rubber and plastics. Its main function is in the mixing and plasticizing of materials. In rubber processing, it can thoroughly mix raw rubber with various additives such as carbon black, vulcanizing agents, and accelerators. Through the shearing and extrusion action of the rollers, the additives are evenly dispersed in the raw rubber, laying the foundation for subsequent vulcanization molding. In plastics processing, the two-roll mill can plasticize plastic raw materials, that is, transform solid plastics into a uniform molten state through heating and mechanical shearing force. It can also fuse different types of plastics or plastics with additives to form mixtures with specific properties. However, during operation, the rollers of the two-roll mill generate heat. If the roller temperature is too high, it may cause premature vulcanization of the rubber, damaging its properties and affecting the subsequent products. Quality stability is crucial in plastic processing. Excessive temperature can cause plastic degradation, leading to decreased material properties, discoloration, cracking, and other issues. It also increases energy consumption, resulting in energy waste, higher scrap rates, and higher production costs. Furthermore, the water used in heating and cooling processes is often consumed only once, with large amounts of hot or cold water being directly discharged. This not only wastes water resources but also causes the loss of heat or cold energy carried by the water, further exacerbating energy consumption. Moreover, the low energy conversion efficiency during temperature control means that excess heat or cold cannot be recovered and reused, resulting in persistently high energy consumption throughout the production process. This contradicts the current concepts of green production and energy conservation. Therefore, those skilled in the art have developed a high-efficiency, energy-saving open mill temperature control device to address the problems mentioned in the background. Utility Model Content

[0008] As a further embodiment of this utility model: the second fixed pipe on the power structure is fixedly connected to a drain pipe on the side away from the first fixed pipe, and a drain valve is fixedly connected to each drain pipe. The drain pipe is rotatably connected to an inlet pipe on the side away from the second fixed pipe, and the roller is fixedly connected to a third fixed pipe on the side away from the first fixed pipe.

[0009] As a further embodiment of this utility model: the side of the third fixed tube away from the roller passes through the side of the first connecting frame and is respectively fixedly connected to the second connecting tube and the third connecting tube. The third fixed tube is rotatably connected to the first connecting frame, and the third connecting tube and the second connecting tube are connected. A second control valve is fixedly connected to the lower tube arm of the second connecting tube. A first connecting tube is fixedly connected to one side of the second connecting tube, and a first control valve is fixedly connected to the first connecting tube.

[0010] As a further embodiment of this utility model: a second water tank is fixedly connected to the side of the first connecting frame away from the roller, a first water tank is fixedly connected to one side of the second water tank, a second protective box is fixedly connected to the top side of the first water tank, a first protective box is fixedly connected to the lower part of the side of the second water tank away from the first water tank, and a water storage tank is fixedly connected to the side of the second connecting frame away from the roller.

[0011] As a further embodiment of this utility model: both the water storage tank and the first water tank are equipped with condenser pipes, and a first cooler and a second cooler are fixedly installed on one side of each. A second delivery pump and a first delivery pump are installed in the second protective box and the first protective box, respectively. One side of the first delivery pump is connected to the pipe of the second water tank, and the other side of the first delivery pump is fixedly connected to the second connecting pipe. One side of the second delivery pump is connected to the pipe of the first water tank, and the other side of the second delivery pump is fixedly connected to the first connecting pipe. A heating pipe is installed in the second water tank.

[0012] As a further embodiment of this utility model: the first water storage tank and the water storage tank are connected by a conveying pipe, and a conveying valve is fixedly connected to one side of the conveying pipe arm. A cooling plate is fixedly connected to the conveying pipe, and the side of the inlet pipe away from the drain pipe is fixedly connected to the water storage tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In use, firstly, the motor in the power structure is started. The motor's power output shaft drives the rotating shaft to rotate, and the driving gear fixed on the rotating shaft also rotates synchronously. The driving gear and the driven gear mesh with each other. Under the meshing action, the driven gear is driven to rotate. The driven gear is fixedly connected to the second fixed tube on one side, which causes the second fixed tube and the first fixed tube connected to it to rotate together, thereby driving the corresponding roller to start rotating. At the same time, the first gear installed on the first fixed tube meshes with the second gear on the other side of the first fixed tube. Under the transmission action of the gears, the roller on the other side also rotates synchronously, ultimately realizing the opposite rotation of the two rollers. This rotation method can generate sufficient shearing and extrusion forces on the material to meet the basic requirements of material mixing.

[0015] 2. When the rollers need to be heated to meet the material processing requirements, the heating pipe in the second water tank will start working to heat the water in the tank to the required temperature. Then, the first conveying pump in the first protective box will start to pressurize the heated hot water. The hot water will be conveyed to the inside of the two rollers through the second connecting pipe, the third connecting pipe and the third fixed pipe in sequence. The hot water flows in the flow channel inside the rollers, fully contacts the inner wall of the rollers and exchanges heat, transferring heat to the rollers and gradually increasing the temperature of the rollers. This heating process can effectively promote the chemical reaction of the materials, allowing the various components in the materials to be more fully integrated, thereby improving the uniformity and physical properties of the product.

[0016] 3. If the rollers become too hot due to friction or other factors during the material mixing process and require cooling, the condenser in the water tank will cool the water under the action of the first cooler, reducing the water temperature in the tank to a suitable range. The cooled water then enters the second and first fixed pipes through the inlet pipe, and then flows into the rollers. As the cold water flows inside the rollers, it absorbs a large amount of heat generated during the operation of the rollers, thereby gradually reducing the temperature of the rollers. This ensures that the materials can be mixed within a suitable temperature range, which is beneficial to improving product quality and production stability.

[0017] 4. After the water entering the roller completes the heat exchange, it will flow out from the drain pipe and into the water storage tank when the drain valve is opened. At this time, if it is necessary to drain the water, the control valve on the water storage tank can be opened and the water will flow out through a special pipe.

[0018] 5. Considering water resource recycling, water can be directly cooled again in the storage tank via condenser tubes. After initial cooling via condenser tubes, the delivery valve on the delivery pipe is opened, and the water is transported through the delivery pipe. While flowing through the delivery pipe, the cooling plate will cool the water flow a second time, allowing for more precise temperature control. Subsequently, the water, after two cooling processes, smoothly enters the first storage tank, which is also equipped with condenser tubes. The second chiller will perform a third deep cooling on the water in the tank, stabilizing the water temperature at a set value suitable for participating in the cooling cycle. When the roller needs to be cooled again, the second delivery pump in the second protective box is activated, transporting the deeply cooled water from the first storage tank through the first connecting pipe to the second connecting pipe, and then through the third connecting pipe and the third fixed pipe back into the roller to continue its cooling effect, achieving efficient water resource recycling and demonstrating the energy-saving characteristics of the device.

After the water entering the roller 6 completes heat exchange, it will flow out from the drain pipe 22 and into the water storage tank 8 when the drain valve 23 is opened. At this time, if it is necessary to drain the water, the control valve on the water storage tank 8 can be opened, and the water will flow out through a special pipe. The side of the third fixed pipe 21 away from the roller 6 passes through the side of the first connecting frame 2 and is respectively fixedly connected to the second connecting pipe 19 and the third connecting pipe 20.

A heating pipe is installed in the second water tank 16. When the roller 6 needs to be heated to meet the material processing requirements, the heating pipe in the second water tank 16 will start to work and heat the water in the tank to reach the temperature required by the process. Then, the first conveying pump in the first protective box 4 starts to pressurize the heated hot water and deliver it to the inside of the two rollers 6, thereby gradually increasing the temperature of the rollers 6. This heating process can effectively promote the chemical reaction of the material and allow the various components in the material to be more fully integrated, thereby improving the uniformity and physical properties of the product.When cooling is required, the condenser in the water tank 8 will cool the water under the action of the first cooler 9, reducing the water temperature in the water tank 8 to a suitable range. As the cooled water flows inside the roller 6, it absorbs a large amount of heat generated during the roller 6's operation, gradually lowering the roller 6's temperature. This ensures that the materials can be mixed within a suitable temperature range, which is beneficial for improving product quality and production stability.

If water recycling is considered, the water can be directly cooled again in the water tank 8 through the condenser before the conveying valve is opened. 12. Water is transported through the conveying pipe 10. While flowing through the conveying pipe 10, the cooling plate 11 performs a secondary cooling of the water flow, allowing for more precise temperature control. Subsequently, the water, after two cooling processes, smoothly enters the first water tank 13. The first water tank 13 is also equipped with a condenser pipe, and the second cooler 14 performs a third deep cooling of the water in the tank, stabilizing the water temperature at a set value suitable for participating in the cooling cycle. When the roller 6 needs to be cooled again, the second conveying pump in the second protective box 15 starts, transporting the deeply cooled water from the first water tank 13 through the first connecting pipe 18 to the second connecting pipe 19, and then through the third connecting pipe 20 and the third fixed pipe 21 back into the roller 6 to continue its cooling effect, achieving efficient recycling of water resources and demonstrating the energy-saving characteristics of the device.
