AI Technical Summary
Existing plasticizer storage tanks have inner liner and outer shell that are directly fixed or have simple support structures, lacking effective buffering and isolation. This causes external forces to be directly transmitted to the inner liner and its heating element, which can easily cause displacement, deformation or damage, affecting heating effect and temperature control accuracy, and posing a risk to use.
The device employs a combination design of inner liner, outer shell, inner partition, flexible pad, insulation layer and buffer mechanism. The flexible pad and insulation layer maintain the elastic isolation of the inner liner, and the buffer mechanism absorbs external impact force to prevent it from being directly transmitted to the inner liner. Combined with a ring electric heater and reinforcing ribs, the device's impact resistance is improved.
It effectively absorbs and attenuates external impact forces, ensuring the stability of the inner tank and the accuracy of temperature control, improving the safety and service life of the equipment, and adapting to frequent handling and complex environments in industrial sites.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of plasticizer storage equipment, specifically an environmentally friendly plasticizer storage tank with a protective structure. Background Technology
[0002] Environmentally friendly plasticizers are important auxiliary materials in plastic processing, rubber products and the production of various industrial materials. They usually have characteristics such as high viscosity, poor flowability and strong temperature sensitivity. In order to make them flowable or usable, they usually need to be heated and kept warm during the storage stage.
[0003] However, existing plasticizer storage tanks generally adopt a structure in which the outer shell and inner liner are directly fixed or simply supported. There is a lack of effective buffer isolation structure between the outer shell and the inner liner. During equipment operation, handling or on-site work, once the outer shell is hit, vibrated or squeezed, the external force will be directly transmitted to the inner liner and its bottom heating element. Since the heater, thermometer, level gauge and other components are mostly located in the inner liner or close to the structure, these parts are prone to displacement, deformation or damage when impacted. This not only affects the heating effect of plasticizer and the accuracy of temperature control, but may also cause equipment failure, posing a great risk of use. Utility Model Content
[0004] To address the shortcomings of existing technologies that commonly employ direct fixing or simple support between the outer shell and inner liner, lacking an effective buffering and isolation structure, where the outer shell is subjected to collision, vibration, or compression, the external force is directly transmitted to the inner liner and its bottom heating element, making it prone to displacement, deformation, or damage upon impact. This not only affects the heating effect and temperature control accuracy of the plasticizer but may also cause equipment failure, posing a significant risk of use, this utility model provides an environmentally friendly plasticizer storage tank with a protective structure.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses an environmentally friendly plasticizer storage tank with a protective structure, comprising an inner liner, an outer shell, and an inner partition. A flexible pad is fixedly connected to the inner side wall of the inner partition, and a heat insulation layer is provided between the flexible pad and the inner liner. A heat insulation plate is fixedly connected to the four sides of the lower surface of the inner liner, and an annular electric heater is provided on the inner bottom wall of the inner partition. The inner sidewall of the inner partition is provided with a buffer mechanism on all four sides to cushion the impact on the outer shell.
[0006] As a preferred embodiment of this utility model, the buffer mechanism includes a vertical base that is uniformly and annularly fixed to the outer side wall of the inner partition. A sliding rod is fixedly connected between the two sides of the inner side wall of the vertical base. Two sliding sleeves are slidably connected to the sliding rod. Springs are fixedly connected to both sides of the inner side wall of the vertical base. The ends of the two springs away from the vertical base are respectively fixedly connected to the two sliding sleeves. A rotating rod is rotatably connected to one side of the outer side wall of each sliding sleeve. A connecting seat is fixedly connected to the end of the inner side wall of the outer shell near the vertical base. The end of the rotating rod away from the sliding sleeve is fixedly connected to the connecting seat.
[0007] As a preferred embodiment of this utility model, a level gauge and a thermometer are provided on the upper surface of the inner liner, and the probes of the level gauge and the thermometer are both located inside the inner liner.
[0008] As a preferred embodiment of this utility model, the lower surface of the outer shell is fixedly connected with columns that are evenly distributed in a ring around the perimeter, and the bottom end of each column is fixedly connected with a base.
[0009] As a preferred embodiment of this utility model, the upper surface of the inner liner is provided with a feed pipe that communicates with the inner liner, and the bottom end of the outer shell is provided with a discharge pipe that penetrates the outer shell and the inner partition and communicates with the inner liner.
[0010] As a preferred embodiment of this utility model, the outer side wall of the outer shell is fixedly connected with vertically uniformly arranged reinforcing ribs, and both sides of the upper surface of the outer shell are provided with lifting lugs.
[0011] In summary, this application has the following beneficial effects: 1. This application utilizes the combination of an inner liner, outer shell, inner partition, flexible pad, insulation layer, heat insulation board, annular electric heater, and buffer mechanism. The inner liner maintains elastic isolation from the inner partition through the flexible pad and insulation layer, thereby absorbing the slight displacement of the inner liner caused by thermal expansion and contraction during heating. When the storage tank is subjected to external impact, vibration, or handling shock, the external force acts on the outer shell first, and the buffer mechanism can absorb and attenuate the impact force, making it difficult for the impact energy to be directly transmitted to the inner partition and inner liner. This ensures the device's impact resistance, anti-displacement, and vibration damping capabilities, thus adapting to industrial site usage scenarios with frequent handling, complex external environments, and high temperature control requirements, significantly improving the safety, reliability, and equipment lifespan of the plasticizer storage process. 2. By adding reinforcing ribs, this application enables the outer shell to have higher overall rigidity and resistance to deformation when subjected to external impacts, lateral compression, or hoisting loads, thereby extending the service life of the entire storage tank.

[0014] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0015] Example: Please refer to Figure 1 and Figure 2 This utility model discloses an environmentally friendly plasticizer storage tank with a protective structure, including an inner liner 1, an outer shell 2, and an inner partition 3. The lower surface of the outer shell 2 is fixedly connected with columns 11 evenly distributed in a ring around its perimeter. The bottom end of the columns 11 is fixedly connected with a base 12. The outer shell 2 is stably supported on the ground by the columns 11 and the base 12. The diameter of the base 12 is larger than the diameter of the outer shell 2, thereby maximizing the grounding area of the device and improving the stability of the device after placement. The outer side wall of the outer shell 2 is fixedly connected with vertically evenly arranged reinforcing ribs 15, which can maximize the overall bending resistance, deformation resistance, and impact resistance of the outer shell 2. Lifting lugs 16 are provided on both sides of the upper surface of the outer shell 2. The lifting lugs 16 are used to lift the entire moving device. The upper surface of the inner liner 1 is provided with a feed pipe 13 that is connected to the inner liner 1. The bottom end of the outer shell 2 is provided with a discharge pipe 14 that passes through the outer shell 2 and the inner partition 3 and is connected to the inner liner 1. In use, plasticizer can be added into the inner liner 1 through the feed pipe 13 and discharged from the inner liner 1 through the discharge pipe 14. Valves are provided on both the feed pipe 13 and the discharge pipe 14 to control the opening and closing of the feed pipe 13 and the discharge pipe 14 respectively. Reference Figure 2 and Figure 3 A flexible pad 4 is fixedly connected to the inner side wall of the inner partition 3. A heat insulation layer 5 is provided between the flexible pad 4 and the inner liner 1. A heat insulation plate 6 is fixedly connected to the four sides of the lower surface of the inner liner 1. An annular electric heater 7 is provided on the inner bottom wall of the inner partition 3. Before discharge, the annular electric heater 7 can heat the plasticizer located at the bottom of the inner liner 1 near the discharge pipe 14 to improve the fluidity of the plasticizer as much as possible, thereby ensuring that the plasticizer discharge is smooth and stable. A level gauge 9 and a thermometer 10 are installed on the upper surface of the inner liner 1. The probes of the level gauge 9 and the thermometer 10 are located inside the inner liner 1. The staff can observe the level and temperature of the plasticizer inside the inner liner 1 through the level gauge 9 and the thermometer 10. The inner sidewall of the inner partition 3 is provided with a buffer mechanism 8 for buffering the impact on the outer shell 2. The buffer mechanism 8 includes a vertical base 81 that is uniformly fixedly connected to the outer sidewall of the inner partition 3 in a ring. A sliding rod 82 is fixedly connected between the two sides of the inner sidewall of the vertical base 81. Two sliding sleeves 83 are slidably connected to the sliding rod 82. Springs 84 are fixedly connected to both sides of the inner sidewall of the vertical base 81. Two springs 84 are fixedly connected to two sliding sleeves 83 at the ends away from the vertical base 81, and rotating rods 85 are rotatably connected to one side of the outer wall of the sliding sleeves 83. Connecting seats 86 are fixedly connected to the end of the inner wall of the outer casing 2 near the vertical base 81, and the end of the rotating rod 85 away from the sliding sleeves 83 is fixedly connected to the connecting seat 86. When the outer shell 2 is subjected to an external impact, the impacted part of the outer shell 2 deforms first. However, since there is a gap between the outer shell 2 and the inner partition 3, the inner partition will not move immediately with the deformation of the outer shell 2. When the outer shell 2 deforms, the corresponding connecting seat 86 at the corresponding position generates a corresponding displacement and pushes the rotating rod 85 to change its angle. The rotating rod 85 pushes the sliding sleeve 83 to move along the sliding rod 82, and at the same time compresses the spring 84. The spring 84 is forced to compress and store energy, so that the impact force on the outer shell is converted into the deformation of the spring 84.
[0016] The implementation principle of this utility model is as follows: When in use, plasticizer can be added into the inner liner 1 through the feed pipe 13. The inner liner 1 is installed inside the inner partition 3, and a flexible pad 4 and an insulation layer 5 are sequentially wrapped between the inner liner 1 and the inner partition 3. The flexible pad 4 can provide circumferential elastic support so that the inner liner 1 can maintain its position as stable as possible when subjected to small displacements and thermal expansion and contraction. When the outer shell 2 is subjected to an external impact, the impacted part of the outer shell 2 deforms first. However, since there is a gap between the outer shell 2 and the inner partition 3, the inner partition will not move immediately with the deformation of the outer shell 2. When the outer shell 2 deforms, the corresponding connecting seat 86 at the corresponding position will generate a corresponding displacement and push the rotating rod 85 to change its angle. The rotating rod 85 pushes the sliding sleeve 83 to move along the sliding rod 82, and at the same time compresses the spring 84. The spring 84 is forced to compress and store energy, so that the impact force on the outer shell is converted into the deformation of the spring 84. When it is necessary to discharge the plasticizer inside the inner liner 1, it can be discharged through the discharge pipe 14. Before discharge, the annular electric heater 7 can heat the plasticizer located at the bottom of the inner liner 1 near the discharge pipe 14 to improve the fluidity of the plasticizer as much as possible, thereby ensuring that the plasticizer discharge is smooth and stable. At this time, the heat insulation layer 5 plays a thermal resistance role, which can minimize the heat loss during the heating process and maintain the temperature uniformity inside the inner liner 1.
[0017] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
