Abstract
Description
Technical Field
[0001] This utility model belongs to the field of oil tank container technology, specifically relating to a ventilation module for a tank container and a tank container having the ventilation module. Background Technology
[0002] In some remote mountainous areas, mining areas, and disaster zones, the construction of conventional gas stations is inconvenient and extremely costly due to their remote location. Furthermore, the temporary nature of construction machinery operations in these areas, with constantly changing work locations, makes fixed gas stations inconvenient for refueling, and they become unusable once the project ends. Therefore, a mobile fuel tanker is designed as a portable refueling device to meet the refueling needs of these special areas.
[0003] Gas station tanks are equipped with vent pipes, which connect the inside and outside of the tank to stabilize the pressure. When the amount of fuel in the tank decreases, air flows into the tank through the vent pipe to ensure stable pressure; when the amount of fuel increases, air flows out of the tank through the vent pipe to ensure stable pressure. This maintains pressure balance inside and outside the tank, preventing safety issues and avoiding abnormal pressure and malfunctions in fuel inlet / outlet operations. Regulations require that the vent pipe opening be at least 4 meters above the ground. Therefore, fuel tanks used for refueling must be equipped with venting modules.
[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention
[0005] This invention addresses the aforementioned problems in the prior art by proposing a ventilation module for a tank container, used to maintain air pressure balance within the tank container and to prevent impurities from entering.
[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution:
[0007] A ventilation module for a tank container, comprising:
[0008] A vent pipe, which is connected to the vent of the tank container;
[0009] A ventilation head is located at the end of the ventilation tube furthest from the ventilation port;
[0010] The vent has a head tube body connected to the vent pipe, a cover body covering the upper end of the head tube body, and a filter screen located inside the head tube body; the cover body has an upturned portion located on the periphery, and the upturned portion forms a vent between itself and the head tube body.
[0011] In some embodiments of this application, the filter screen is a cylindrical shape sleeved on the outside of the vent pipe, the head tube body is provided with a support platform extending radially outward, and the lower end of the filter screen is located on the support platform.
[0012] In some embodiments of this application, the upper end of the filter screen abuts against the cover, and the cover has an arc-shaped lower protrusion extending downward from the center, the lower protrusion extending into the filter screen.
[0013] In some embodiments of this application, the cover has a plurality of fixing portions spaced apart along the upper end of the lower protrusion, and the fixing portions and the upper protrusion are alternately arranged in the circumferential direction of the cover.
[0014] In some embodiments of this application, the fixing part has a fixing side that extends horizontally in the radial direction and a transition side that connects the outer side of the lower protrusion and the inner side of the fixing side, the transition side being inclined downward in the outward direction.
[0015] In some embodiments of this application, the fixing part further has two connecting edges that are respectively connected to the two upturned portions on both sides of the fixing edge and the transition edge, and the upturned portions, the connecting edges, and the upper end of the head tube body surround to form the vent.
[0016] In some embodiments of this application, the connecting edge is inclined in an upward direction away from the fixed edge, and the outer side of the upward-curved portion is provided with a radially extending horizontal edge.
[0017] In some embodiments of this application, the head tube has a body tube connected to the outer end of the support platform, and a fixing edge extending radially outward along the upper end of the body tube, wherein the fixing part and the fixing edge are fastened by screws.
[0018] In some embodiments of this application, the head tube has a fixed cylinder sleeved on the outside of the vent pipe, and a plurality of threaded holes are opened in the circumferential direction of the fixed cylinder. Bolts are fixed in the threaded holes, and the inner end of the bolts abuts against the vent pipe. The inner wall of the fixed cylinder is radially outward in the downward direction.
[0019] Based on the above-mentioned ventilation module, this utility model also provides a tank box with the ventilation module. By setting the ventilation module, the air pressure balance inside the tank box can be maintained, and impurities can be prevented from entering.
[0020] A tank container having the above-mentioned ventilation module.
[0021] Compared with existing technologies, the advantages and positive effects of this utility model are as follows: The vent pipe is connected to the tank vent, and the vent head is located at the end of the vent pipe away from the vent. When the volume of oil in the tank changes, air can enter and exit the tank through the vent of the vent head and the vent pipe, effectively maintaining the pressure balance inside and outside the tank. This avoids problems such as tank deformation, difficulty in oil intake, or poor oil output caused by abnormal air pressure, ensuring the safe and stable operation of the tank. A filter screen is installed inside the vent head, which can filter out dust, impurities, and other particles in the air during the air intake and exhaust process, preventing them from entering the tank and contaminating the oil, ensuring oil quality, and avoiding damage to refueling equipment and receiving machinery caused by impurities. The upturned part around the cover and the head pipe form a vent. This design increases the ventilation area, making airflow smoother; during rapid oil intake or output, the air pressure can be adjusted in time, reducing pressure fluctuations and improving refueling efficiency. At the same time, the cover can also prevent rainwater and foreign objects from falling directly into the vent head to a certain extent, reducing the risk of rainwater and other substances entering the tank and ensuring that the oil inside the tank is not affected by external liquids.

[0041] See Figures 1-7 This is one embodiment of a venting module for a tank container proposed in this utility model. The venting module includes a vent pipe 50 and a vent head 59. The vent pipe 50 is connected to a vent port 122 in the tank container. The tank container 100 has a tank body 10, and the tank body 10 has a single-layer top plate 12. A vent port 122, which can be connected to the vent pipe 50, is provided on the top plate 12. A removable plug 123 is provided at the vent port 122. The vent head 59 is located at the end of the vent pipe 50 away from the vent port 122.
[0042] The vent head 59 has a head tube body 591 connected to the vent pipe 50, a cover body 592 covering the upper end of the head tube body 591, and a filter screen 593 located inside the head tube body 591. The cover body 592 has an upturned portion 5922 located on the periphery, and an air vent 594 is formed between the upturned portion 5922 and the head tube body 591. The vent pipe 50 is connected to the air vent 122 of the tank 100, and the vent head 59 is located at the end of the vent pipe 50 away from the air vent 122. When the volume of oil in the tank 10 changes, air can enter and exit the tank 10 through the air vent 594 of the vent head 59 and the vent pipe 50, effectively maintaining the air pressure balance inside and outside the tank 10, avoiding problems such as deformation of the tank 10, difficulty in oil intake, or poor oil output caused by abnormal air pressure, and ensuring the safe and stable operation of the tank 10. A filter 593 is installed inside the vent head 59 to filter out dust, impurities, and other particles in the air during the airflow into and out of the tank, preventing them from entering the tank and contaminating the oil, ensuring oil quality, and avoiding damage to refueling equipment and receiving machinery caused by impurities. The upturned portion 5922 around the cover 592 forms a vent 594 with the head tube 591. This design increases the ventilation area, making airflow smoother; it can also adjust the air pressure in time during rapid oil intake or output, reducing pressure fluctuations and improving refueling efficiency. At the same time, the cover 592 can also prevent rainwater and foreign objects from falling directly into the vent head 59 to a certain extent, reducing the risk of rainwater and other substances entering the tank 10 and ensuring that the oil inside the tank 10 is not affected by external liquids.
[0043] In some embodiments of this application, the filter 593 is a cylindrical shape fitted over the outside of the vent pipe 50, and the head tube 591 has a radially outwardly extending support platform 5911, with the lower end of the filter 593 located on the support platform 5911. The cylindrical filter 593 fitted over the outside of the vent pipe 50 increases the filter area within a limited space, improving filtration efficiency. The support platform 5911 provides stable support for the filter 593, making installation easier; simply place its lower end on the support platform 5911. Simultaneously, it ensures that the filter 593 is fixed in position within the vent head 59, preventing it from shaking or shifting due to airflow or other external forces, thus guaranteeing the stability of the filtration effect.
[0044] In some embodiments of this application, the upper end of the filter screen 593 abuts against the cover 592. The cover 592 has an arc-shaped lower protrusion 5921 extending downward from its center, and the lower protrusion 5911 extends into the filter screen 593. The upper end of the filter screen 593 abuts against the cover 592, and together with the lower support platform 5911, achieves vertical positioning of the filter screen 593 within the vent head 59, preventing its axial movement. The lower protrusion 5921 extends into the filter screen 593, constraining the filter screen 593 from its central position, further limiting the radial movement of the filter screen 593, keeping the filter screen 593 stable within the vent head 59, and ensuring the reliability of the filtration effect. The arc-shaped lower protrusion 5921 increases the structural strength of the cover 592, enabling it to better withstand external pressure and impact, reducing the possibility of deformation or even damage to the cover 592 due to external forces, thereby protecting the filter screen 593 and other components inside the vent head 59, and extending the service life of the venting module.
[0045] In some embodiments of this application, the cover 592 further has a plurality of fixing portions 5923 spaced apart along the upper end of the lower protrusion 5921, with the fixing portions 5923 and the upturned portions 5922 alternating in the circumferential direction of the cover 591. The alternating arrangement of the plurality of fixing portions 5923 and the upturned portions 5922 in the circumferential direction of the cover 592 makes the distribution of the vents 594 more uniform. When air enters the vent head 59, it will flow along a specific path under the guidance of the fixing portions 5923 and the upturned portions 5922. On the one hand, this allows the air to pass through the filter 593 more uniformly, improving the utilization efficiency of the filter 593; on the other hand, this uniform airflow distribution helps to reduce airflow turbulence and eddy currents, reduce airflow resistance, and make the air flow into and out of the tank 10 smoother, thus more effectively maintaining the air pressure balance inside and outside the tank 10.
[0046] In some embodiments of this application, the fixing part 5923 has a fixing edge 59231 extending radially horizontally and a transition edge 59232 connecting the outer side of the lower protrusion 5911 and the inner side of the fixing edge 59231. The transition edge 59232 is inclined downward in the outward direction. The fixing edge 59231 extends radially horizontally, providing a more stable support structure for the cover 592. It can increase the connection strength between the cover 592 and the head tube 591, making the cover 592 less prone to shaking or displacement when subjected to external forces, such as wind or vibration. At the same time, the transition edge 59232 connects the lower protrusion 5921 and the fixing edge 59231, forming a stable triangular structure, further enhancing the overall structural strength of the cover 592, enabling it to better withstand external pressure and protect the internal components of the vent head 59.
[0047] In some embodiments of this application, the fixing part 5923 further has two connecting edges 59233 that are respectively connected to the two upturned parts 5922 on both sides of the fixing edge 59231 and the transition edge 59232. The upturned parts 5922, the connecting edges 59233, and the upper end of the head tube 591 form a vent 594. The connecting edges 59233 connect the fixing part 5923 and the upturned parts 5922, making the structure of the cover 592 more stable. The connection between the connecting edges 59233 and the upturned parts 5922 increases the sealing of the periphery of the cover 592 to a certain extent. When rainwater falls on the cover 592, it can guide the rainwater to flow along the surface of the upturned parts 5922 and the connecting edges 59233 to the edge of the cover 592, reducing the possibility of rainwater entering the interior of the vent head 59 through the vent 594.
[0048] In some embodiments of this application, the connecting edge 59233 is inclined in an upward direction away from the fixed edge 59231, and the outer side of the upturned portion 5922 is provided with a radially extending horizontal edge 59221. The radially extending horizontal edge 59221 on the outer side of the upturned portion 5922 can, to some extent, prevent rainwater from splashing into the vent 594 from the side. The horizontal edge 59221 provides additional support for the upturned portion 5922, enhancing its structural strength.
[0049] In some embodiments of this application, the head tube 591 has a body tube 5910 connected to the outer end of the support platform 5911, and a fixing edge 5912 extending radially outward along the upper end of the body tube 5910. The fixing part 5923 and the fixing edge 5912 are fastened together by screws. The fixing edge 5912 and the fixing part 5923 are fastened together by screws. This connection method makes the assembly and disassembly of the vent head 59 convenient and easy.
[0050] In some embodiments of this application, the head tube 591 has a fixing cylinder 5913 sleeved on the outside of the vent pipe. Multiple threaded holes are formed in the circumference of the fixing cylinder 5913, and bolts 595 are fixed in these threaded holes, with the inner end of the bolt abutting against the vent pipe 50. The tightness between the head tube 591 and the vent pipe 50 can be adjusted by tightening the bolts to ensure a secure connection. The inner wall of the fixing cylinder 5913 is radially outwardly inclined in the downward direction, which facilitates the fitting of the head tube 591 onto the outside of the vent pipe 50 and makes the installation of the vent head 59 easier.
[0051] In some embodiments of this application, the vent pipe 50 has multiple detachably connected pipe segments 51, and a fixing bracket 60 is provided on the top plate 12 for fixing the multiple pipe segments 51 during transportation. The vent pipe 122 is composed of multiple detachably connected pipe segments 51. During transportation, the pipe segments 51 can be disassembled and fixed using the fixing bracket 60 on the top plate 12. This reduces the transportation volume and facilitates the transportation of the tank container 100 to remote mountainous areas, mining areas, disaster areas, and other special areas, reducing transportation difficulty and cost. After arriving at the destination, the pipe segments 51 of the vent pipe can be easily assembled and connected to the vent port 122 on the top plate 12. The installation process is simple and quick. In use, the vent pipe 50 can stabilize the air pressure in the oil tank by connecting the air inside and outside the oil tank, maintaining the air pressure balance inside and outside the oil tank, and avoiding safety problems such as oil inlet / outlet failures caused by abnormal oil tank pressure. A removable plug is provided at the vent 122. When the vent pipe 50 is not needed, it can be blocked to prevent debris from entering the tank. When it is needed, it can be opened again. The use of the vent pipe can be flexibly selected according to the actual situation, which improves the flexibility of the oil tank container.
