[0002] High-density polyethylene (HDPE) oxidized wax is produced by cracking, polymerizing, and fully oxidizing HDPE in a high-temperature, high-pressure reactor. It exhibits high stability and lubricity. During storage, to avoid the effects of overheating or underheating that could affect product quality and lifespan, the storage temperature should be controlled between 15℃ and 25℃, and should not fall below 5℃ or exceed 50℃. However, some current HDPE oxidized wax storage devices lack temperature control functions, relying entirely on ambient temperature, making stable temperature management difficult. Other devices, while equipped with temperature control systems, are limited to external heating or cooling, lacking comprehensive and uniform temperature control methods and exhibiting low temperature regulation efficiency. This can easily lead to significant fluctuations in the storage environment temperature, adversely affecting product quality. Utility Model Content

[0016] Figure 1 This is a schematic diagram of one structure of the present utility model. Detailed Implementation
[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] Reference Figure 1 A high-density oxidized polyethylene wax storage device includes a storage bin 1 for storing high-density oxidized polyethylene wax. The top of the storage bin 1 is provided with a feed inlet to facilitate the rapid input of high-density oxidized polyethylene wax. The feed inlet is sealed by a sealing cover 2 to achieve a tight seal and ensure that the wax is not contaminated by the external environment during storage. The bottom of the storage bin 1 is provided with a discharge outlet, which is connected to a discharge pipe 3 to provide a channel for the smooth output of the wax. A discharge pump 4 and a discharge control valve 5 are installed on the discharge pipe 3 to work together to precisely control the discharge speed and amount of wax.
[0019] A return pipe 6 is also connected to the discharge pipe 3 between the discharge pump 4 and the discharge control valve 5. The existence of the return pipe 6 allows a portion of the wax material to be redirected back to the storage bin 1 during the discharge process, thereby realizing the recycling of the wax material and temperature regulation. Specifically, a return control valve 7 is installed on the return pipe 6 at the junction of the return pipe 6 and the discharge pipe 3. Through it, the flow rate of the return material can be easily controlled. The other end of the return pipe 6 extends upward and connects to the upper part of the storage bin 1, forming a complete return operation.
[0020] To improve the heat exchange efficiency during the material return process, a heat exchange jacket 8 is fitted onto the material return pipe 6. A heat exchange gap is left between the inner wall of the heat exchange jacket 8 and the outer wall of the material return pipe 6, providing space for heat transfer. A heat exchange inlet and outlet pipe communicating with the heat exchange gap is installed on the heat exchange jacket 8, which can inject cooling or heating media into the heat exchange gap to regulate the temperature of the wax material in the material return pipe 6. Preferably, the material return pipe 6 at the heat exchange gap is curved, and several heat exchange fins 9 are installed on the outer wall of the material return pipe 6 at the heat exchange gap, which helps to improve the heat exchange efficiency.
[0021] To monitor the temperature of the storage silo 1, several thermometers 13 are installed on the storage silo 1. Preferably, three thermometers 13 are installed, which are respectively inserted into the upper, middle and lower parts of the storage silo 1. More preferably, the thermometers 13 are bimetallic thermometers, so as to monitor the temperature at different locations in the storage silo 1 in real time, providing accurate data support for operators to adjust the temperature in a timely manner and ensure that the wax is in the best storage condition.
[0022] To ensure a more uniform storage temperature for the high-density oxidized polyethylene wax in storage silo 1 and to guarantee comprehensive and sufficient temperature regulation, a horizontally arranged support shaft 10 is installed on the upper side of storage silo 1. One end of the support shaft 10 is located inside storage silo 1 and is equipped with a stirring plate 11, while the other end of the support shaft 10 is located outside storage silo 1. A drive cylinder or electric push rod 12 is installed on storage silo 1 to drive the support shaft 10 to move laterally back and forth, facilitating the movement of the support shaft 10 and the stirring plate 11 within storage silo 1 as needed, thereby agitating the wax and enabling rapid mixing of the wax input through return pipe 6 with the wax in storage silo 1, improving temperature regulation efficiency. A reciprocating dynamic seal is installed at the junction of the support shaft 10 and storage silo 1 to prevent leakage of storage silo 1 during operation of the stirring plate 11.
[0023] In actual use, in order to improve the insulation effect of the entire storage device and reduce heat loss, insulation layers are installed on the outside of the storage bin 1 and the heat exchange jacket 8 to ensure the temperature stability of the wax during storage.
[0024] The specific usage process of this utility model is as follows:
[0025] I. Preparation Stage
[0026] Before use, the entire storage device needs to be thoroughly inspected to ensure that all components are intact, connections are tight, and there are no leaks.
[0027] According to the storage requirements of high-density oxidized polyethylene wax, if it is necessary to heat or cool the wax to a specific temperature, the heating or cooling system in the heat exchange jacket 8 can be started in advance to preheat or precool the return pipe 6 and the storage bin 1.
[0028] II. Feeding Stage
[0029] Use a special tool to open the sealed top cover 2 of the storage bin 1 to ensure that the feed inlet is unobstructed;
[0030] High-density oxidized polyethylene wax is added into storage bin 1 through the inlet. The wax can be delivered by tank truck, pump or other conveying equipment.
[0031] After the wax material is added, close the sealing cover 2 in time and ensure that it is well sealed to prevent outside air and impurities from entering the storage silo 1.
[0032] III. Temperature Regulation and Storage Stage
[0033] Start the thermometer 13 installed on the upper part of the storage silo 1 to monitor the temperature at different locations inside the storage silo 1 in real time;
[0034] Based on the data fed back by thermometer 13, the flow rate and temperature of the heating or cooling medium in the heat exchange jacket 8 are adjusted by the control system to keep the wax material in the storage bin 1 within a suitable storage temperature range.
[0035] As needed, the flow rate of wax in the return pipe 6 can be controlled by adjusting the opening of the return control valve 7. When the temperature in the storage bin 1 is too high, the return amount can be increased to cool it down; when the temperature is too low, the return amount can be reduced to keep the temperature stable.
[0036] During storage, the storage device needs to be inspected regularly to check the thermometer 13 reading, the working status of the heat exchange jacket 8, whether the return pipe 6 is unobstructed, and whether there are any leaks.
[0037] IV. Discharge Stage
[0038] When discharge is required, first open the discharge control valve 5 to allow the wax material to flow out from the bottom of the storage bin 1.
[0039] In summary, this high-density oxidized polyethylene wax storage device achieves precise temperature control and stable storage of wax through precise temperature monitoring and feedback, efficient heat exchange jacket 8 and return pipe 6 design, flexible return control valve 7 adjustment, and advanced control system and insulation layer settings.
