Description

Technical Field

[0001] This utility model relates to the technical field of liquid auxiliary material feeding, and in particular to a liquid auxiliary material addition device for a dust-free modifier production line. Background Technology

[0002] In the manufacturing process of powder modifiers, the application of liquid additives is an indispensable part. Traditional methods typically involve precisely weighing various types of liquid additives according to a predetermined volume ratio and directly adding them to a mixing device containing the main powder raw materials for stirring. However, as the industry's requirements for production environment and product quality continue to increase, the limitations of traditional feeding and mixing methods are becoming increasingly apparent.

[0003] In recent years, dust-free modifier production lines have been widely used as an advanced production model. The core advantage of this production line lies in its precisely designed negative pressure pipeline conveying system, which connects all production equipment in series, achieving fully automated management from raw material storage and transportation to the final product. Especially when processing powdery raw materials, dedicated silos ensure that the raw materials can be quickly and safely transferred to the next processing stage when needed, greatly reducing the risk of dust pollution and improving production continuity and efficiency.

[0004] For the feeding process of liquid additives, a dust-free production line offers a more refined solution. The liquid additives are stored in specially designed containers, and using pumping equipment and a supporting piping system, they can be precisely delivered to a liquid metering device for quantitative control. Subsequently, they enter the mixing stage along with the main raw materials and other additives to complete the preparation of the modifier. This process not only ensures the accuracy of material proportions but also enhances the controllability and traceability of the entire production process.

[0005] However, current liquid additive delivery mechanisms still face some challenges:

[0006] Different types of liquid excipients play different roles in modifier products due to their varying chemical properties. Therefore, their state during mixing and stirring has specific requirements, with temperature control being particularly critical. Current technologies often heat the liquid excipients only when they begin to mix with other components. This not only prolongs the production cycle but may also lead to unstable product quality, thereby affecting the overall production efficiency and performance of the modifier.

[0007] In view of this, the inventors specifically designed a liquid additive device for a dust-free modifier production line, which led to this invention. Utility Model Content

[0008] To solve the above problems, the technical solution of this utility model is as follows:

[0009] A liquid additive addition device for a dust-free modifier production line includes several material cylinders, a pumping device, a pumping pipeline, a liquid metering device, a control valve, and a stirring device. Each material cylinder is connected to the liquid metering device via a pumping pipeline, and the pumping pipeline is equipped with a pumping device and a control valve to provide liquid delivery power and control pipeline on / off. The liquid metering device is connected to the stirring device via a connecting pipeline and another control valve to cooperate with the stirring and mixing of other raw materials.

[0023] The beneficial effects of this utility model are as follows:

[0024] This invention integrates a heating device inside at least one material cylinder, forming a liquid storage chamber with a preheating function. It incorporates two key temperature monitoring points: a first temperature probe monitors the temperature of the liquid additive within the storage chamber in real time, while a second temperature probe monitors the temperature of the liquid additive before it enters the mixing device.

[0035] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0036] Please see Figures 1 to 5 This is a liquid additive device for a dust-free modifier production line, which is the preferred embodiment of this utility model. It includes several material cylinders 10, a pumping device 20, a pumping pipeline 30, a liquid metering device 40, a control valve 50, and a stirring device 60. Each material cylinder 10 is connected to the liquid metering device 40 via the pumping pipeline 30, and the pumping pipeline 30 is equipped with the pumping device 20 and the control valve 50 to provide liquid delivery power and control pipeline on / off. The liquid metering device 40 is connected to the stirring device 60 via a connecting pipeline 41 and another control valve 50 to cooperate with the stirring and mixing of other raw materials.

[0037] A liquid storage chamber 11 is formed inside the material cylinder 10 for storing liquid auxiliary materials. The liquid storage chamber 11 is covered with a heat-insulating jacket layer 12 for heat preservation.

[0038] At least one liquid storage chamber 11 is provided with a heating device for heating the liquid auxiliary material in the liquid storage chamber 11;

[0039] A first temperature-sensing probe 13 is provided in the liquid storage chamber 11 equipped with a heating device to monitor the first temperature of the liquid auxiliary material in the liquid storage chamber 11.

[0040] A second temperature probe 43 is provided in the connecting pipe 41 to monitor the second temperature of the liquid auxiliary material before it is input into the stirring device 60.

[0041] In this embodiment, the liquid metering device 40 is a 50kg liquid metering scale mounted on a high position via a bracket 42, the stirring device 60 is located below the liquid metering device 40, several material cylinders 10 are placed on the floor of the production line workshop, and the pumping pipeline 30 extends from the bottom of the material cylinders 10 to the liquid metering device 40 at the high position.

[0042] In this embodiment, as Figure 1 , 2 As shown in Figure 3, there are two material cylinders 10, one of which is a material cylinder 10 with a heating device. The pumping pipeline 30 connected to this material cylinder 10 is covered with a heat insulation layer 31 made of polyurethane material. Thus, the heat insulation layer 31 can minimize the heat loss of liquid auxiliary material during pumping, reduce the heat loss during the transfer to the liquid metering device 40, maintain its temperature, and achieve a certain energy-saving effect.

[0043] Preferred, such as Figure 1 As shown, the pumping pipeline 30 with heating device has a flange connection section 32 at one end near the liquid metering device 40. The flange connection section 32 is connected to the flanges of the pumping pipeline 30 at both ends, and the control valve 50 is located on one side of the flange connection section 32.

[0044] In this embodiment, the control valve 50 on the pumping pipeline 30 is a pneumatic ball valve DN25, which is used to control the opening and closing of the pumping pipeline 30 in order to cooperate with the pumping device 20 to realize the feeding of liquid auxiliary materials.

[0045] In this embodiment, the connecting pipe 41 is provided with another flange connection section 32 and another pneumatic ball valve DN32 to realize the feeding control of the liquid metering device 40.

[0046] Preferred, such as Figure 1 , 2 As shown, in this embodiment, the pumping device 20 is a gear oil pump, which can provide power to transport liquid auxiliary materials from the material cylinder 10 to the liquid metering device 40.

[0047] Preferred, such as Figure 4 As shown, both the first temperature-sensing probe 13 and the second temperature-sensing probe 43 are rod-shaped temperature sensors with probes for detecting temperature changes, and they are inserted into corresponding pipes. When the liquid auxiliary material flows through the probes, its real-time temperature is obtained.

[0048] Preferably, it also includes a first control module 70, and the heating device includes a second control module 80 and a heating module 90 electrically connected to the output terminal of the second control module 80. The first control module 70 and the second control module 80 are bidirectionally connected. The first temperature probe 13 is electrically connected to the input terminal of the second control module 80, and the second temperature probe 43 is electrically connected to the input terminal of the first control module 70.

[0049] Furthermore, a number of tuning fork level gauges 14 are provided on one side of the material cylinder 10 along its height direction.

[0050] Furthermore, both the first control module 70 and the second control module 80 are MCU microprocessors.

[0051] Thus, by inserting a rod-shaped temperature sensor into the corresponding pipe, the temperature data of the liquid auxiliary material is acquired in real time, ensuring the accuracy and response speed of temperature measurement and providing a reliable basis for subsequent temperature control. The intelligent control system consists of a first control module 70 and a second control module 80, which are connected through bidirectional communication to coordinate the working status of the heating device, ensuring that the liquid auxiliary material is maintained at the optimal temperature throughout the conveying process, thereby improving mixing efficiency and product consistency. In addition, a tuning fork level gauge 14 installed along the height direction on one side of the material cylinder 10 can monitor the liquid level in real time, preventing overfilling or idling, and ensuring the continuity and safety of the production process. The first and second control modules 80, which use MCU microprocessors, not only have the characteristics of high performance and low power consumption, but can also efficiently handle complex temperature control and data transmission tasks, ensuring stable operation and precise control of the system. In summary, this intelligent temperature control system, combined with the material level monitoring function, effectively improves the efficiency, quality, and reliability of modifier production, meeting the needs of the modern chemical industry for efficient, clean, and high-quality production.

[0052] Preferred, such as Figure 2 , 3 As shown, the material cylinder 10 includes a cylinder body 15 and a cylinder cover 16 hinged to the cylinder body 15. A hanging seat 17 is provided at the bottom center of the cylinder cover 16. The heating module 90 includes a heating element 91 and a heat-conducting element 92. The heating element 91 is movably hung on the hanging seat 17 through a hanging plate 18. The heat-conducting element 92 is spirally distributed at the lower end of the heating element 91, and the heat-conducting element 92 is divided into an enlarged section 921 with the radius increasing downwards and a cylindrical section 922 with the same radius.

[0053] Furthermore, the hanging plate 18 includes a fixing plate 181 and a hook portion 182. The hanging base 17 is provided with a hanging hole 171. The portion of the hook portion 182 passing through the hanging hole 171 and located on both sides of the hanging hole 171 is respectively fixed with a limit plate 183 and a locking cap 184 threadedly connected.

[0054] Therefore, by flipping the cylinder cover 16, the bracket 17 can be lifted, and the heating module 90 connected to the bracket 17 will be pulled up accordingly. Through the rotational connection between the hanging plate 18 and the bracket 17, the heating element 91 and the heat-conducting element 92 will always remain vertical during the process of being pulled up, so as to avoid damage to them due to force.

[0055] Furthermore, the design of the hanging hole 171, hook part 182, limiting plate 183 and locking cap 184 makes the installation and removal of the heating element 91 and the heat conduction element 92 more convenient and quick, and facilitates the maintenance and replacement of the heating device.

[0056] In this embodiment, the heating element 91 and the heat-conducting element 92 are based on the principle of resistance heating, which will not be elaborated here. The design of the enlarged section 921 and the cylindrical section 922 of the heat-conducting element 92 enables it to be more evenly distributed in the liquid storage cavity 11, thereby enhancing the heating effect on the liquid auxiliary material.

[0057] Specifically, in this embodiment, combined with Figure 1 On the flange connection section 32 of the pumping pipeline 30, a third temperature probe 33 is provided on the other side of the control valve 50. The third temperature probe 33 is also the same temperature sensor as the first temperature probe 13. Its function is to detect the temperature state of the liquid auxiliary material before it enters the liquid metering device 40. Thus, by adding a third temperature probe 33, the accuracy and reliability of temperature monitoring of the liquid auxiliary material in management can be further enhanced, ensuring that the liquid auxiliary material has reached the preset temperature requirements before entering the liquid metering device 40. This not only provides additional temperature data points, making the temperature change in the entire conveying process more transparent and controllable, but also allows for timely corrective measures to be taken when temperature abnormalities are detected, avoiding product quality problems caused by substandard temperature.

[0058] The beneficial effects of this utility model are as follows:

[0059] This invention integrates a heating device inside at least one material cylinder 10, forming a liquid storage chamber 11 with a preheating function. It incorporates two key temperature monitoring points: a first temperature probe 13 for real-time monitoring of the liquid auxiliary material temperature within the storage chamber 11, and a second temperature probe 43 for monitoring the temperature of the liquid auxiliary material before it enters the mixing device 60. Through feedback from these two temperature probes, the heating device can precisely adjust the temperature of the liquid auxiliary material, ensuring it remains in optimal condition throughout the conveying and mixing process.

[0060] By combining the aforementioned preheating mechanism with real-time temperature monitoring, liquid additives can be heated to a suitable mixing temperature in advance, and adjustments can be made dynamically according to actual needs, avoiding the problem of heating only after mixing has begun in traditional methods. This not only shortens the production cycle and improves mixing efficiency but also ensures the quality and consistency of the modifier product, thereby significantly improving the overall production line's efficiency and reliability.

[0061] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
