Description

Technical Field

[0001] This utility model relates to the technical field of carbon dioxide production equipment, and more specifically, to a carbon dioxide storage tank filling device. Background Technology

[0002] In the production of carbon dioxide, high-purity carbon dioxide needs to be stored in steel cylinders. During filling, the cylinders undergo visual inspection and are evacuated before being filled with carbon dioxide. Currently, the filling process typically uses pressure testing, weight testing, or level testing to determine if the cylinder is full. Level testing requires a carbon dioxide cylinder equipped with a level gauge, and observing the liquid carbon dioxide level inside the cylinder places high demands on the cylinder's specifications. Pressure testing operates on the principle that, at constant temperature, gas pressure is inversely proportional to volume. When the cylinder is full of carbon dioxide, the pressure reaches a relatively stable value; reading the pressure gauge reading determines fullness. This method requires high precision in terms of ambient temperature and instrument accuracy. Weight testing compares the actual weight of the cylinder with the weight of the empty cylinder, along with the known density of carbon dioxide gas, to determine fullness. Because weight testing has lower requirements for environmental conditions and equipment, it is now widely used in industrial carbon dioxide production.

[0003] When using the weight detection method, the weight of the carbon dioxide cylinder needs to be monitored in real time during the filling process. Once the weight reaches a threshold, the cylinder is preliminarily considered full, and filling is stopped. After filling, the cylinder is placed back on the electronic scale to measure its total weight. This weight value is recorded for comparison and calculation. In the current filling process, the upper end of the carbon dioxide cylinder needs to be fixed, and the lower end placed on the weight detection mechanism. Using the existing detection structure, the force on the upper end of the cylinder may lead to errors in weight detection, thus requiring a second weighing; this is time-consuming and labor-intensive.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Reference Figures 1 to 4As shown, this utility model discloses a carbon dioxide storage tank filling device, which includes a support base 100, a fixed bracket 200, and a filling mechanism 300. The support base 100 is provided with a bottom plate 110 and a support plate 120, which are slidably connected vertically. A storage cylinder 400 is placed on the support plate 120, and a weight sensor 130 is provided between the bottom plate 110 and the support plate 120. The fixed bracket 200 is connected to the support plate 120, and two fastening components 210 are adjustable vertically on the fixed bracket 200. Each of the two fastening components 210 is provided with a push plate 211, and the push plates 211 on both sides of the storage cylinder 400 can abut against the storage cylinder 400 horizontally. The filling mechanism 300 is provided with an inflation head 310 at the upper end of the fixed bracket 200, and the inflation head 310 is detachably connected to the valve 410 of the storage cylinder 400. Specifically, in this embodiment, the storage cylinder 400 is placed on the support plate 120, and its own weight will cause the support plate 120 to bear pressure. Since the base plate 110 and the support plate 120 are slidably connected in the vertical direction, as the carbon dioxide in the storage cylinder 400 is continuously filled, the weight of the storage cylinder 400 increases, and the support plate 120 will slide downward relative to the base plate 110. At this time, the weight sensor 130 located between the base plate 110 and the support plate 120 will sense the pressure change and convert it into an electrical signal. By analyzing and processing the electrical signal, the real-time weight of the storage cylinder 400 is obtained, thereby determining whether the storage cylinder 400 has reached the preset filling weight, and realizing the monitoring of the filling amount. The fixed bracket 200 is connected to the support plate 120 to ensure synchronous movement with the support plate 120 on which the storage cylinder 400 is placed. The two fastening components 210 are adjustable in the vertical direction on the fixed bracket 200. For storage cylinders 400 of different heights, the fastening components 210 can be adjusted to a suitable height position. Then, by operating the pusher plate 211, it is moved horizontally until both pusher plates 211 are firmly against the storage cylinder 400, stabilizing the storage cylinder 400 horizontally and preventing it from shaking or shifting during filling, thus ensuring the stability and safety of the filling process. The filling mechanism 300 is installed on the upper end of the fixed bracket 200, and its inflation head 310 is detachably connected to the gas valve 410 of the storage cylinder 400. During the filling operation, the inflation head 310 is accurately connected to the gas valve 410 of the storage cylinder 400, and the filling equipment is turned on. Carbon dioxide gas then enters the storage cylinder 400 through the inflation head 310. After filling is completed, the inflation head 310 is removed from the gas valve 410, thus completing one filling operation. This allows for convenient and quick filling of different storage cylinders 400. In this embodiment, the support base 100 is provided with a base plate 110 and a support plate 120. The storage cylinder 400, the fixed bracket 200 and the filling mechanism 300 are all provided on the support plate 120 to form a whole.During gas filling of the storage cylinder 400, regardless of the clamping method used, the clamping force is an internal force and cannot affect the weight sensor 130 located between the base plate 110 and the support plate 120 in collecting the weight of the upper part. This structural design allows for rapid determination of the carbon dioxide storage cylinder 400's status with high detection accuracy.

[0034] In some embodiments of this utility model, a support channel steel 111 is provided at the bottom of the base plate 110. Specifically, in this embodiment, in the scenario of batch gas filling of storage cylinders 400, multiple devices need to work together. The support channel steel 111 is set at the bottom of the base plate 110 and can dock with the slide rail. When multiple devices are arranged side by side, the support channel steel 111 and the slide rail cooperate with each other. The interval between adjacent devices can be flexibly changed according to actual needs, thereby constructing a multi-station gas filling system that meets the requirements of different filling tasks. Each device finds a suitable position on the slide rail and is fixed by the support channel steel 111, realizing the orderly arrangement and collaborative work of multiple devices to jointly complete the batch filling task. In addition, the support channel steel 111 has a certain strength and structural stability. As a supporting component of the base plate 110, it can evenly distribute the weight of the base plate 110 and the entire device, including the storage cylinders 400, the fixed brackets 200, and the filling mechanism 300 placed on the support plate 120, onto the ground or load-bearing structure. The support channel steel 111 provides a solid support foundation for the entire device, ensuring that the device does not sway or tilt during the filling process due to its own weight or external factors, such as slight vibrations during filling, thus maintaining the normal operation of the device.

[0035] In some embodiments of this utility model, a positioning post 112 is provided on the upper end surface of the base plate 110, and a positioning groove 121 is provided on the lower end of the support plate 120. The support plate 120 is fitted onto the positioning post 112 through the positioning groove 121. Specifically, in this embodiment, the positioning post 112 is provided on the upper end surface of the base plate 110, and the positioning groove 121 is provided on the lower end of the support plate 120. When the support plate 120 needs to be installed, the positioning groove 121 on the support plate 120 is aligned with the positioning post 112 on the base plate 110, and then the support plate 120 is fitted onto the positioning post 112. This design utilizes the cooperation relationship between the positioning post 112 and the positioning groove 121 to restrict the degree of freedom of movement of the support plate 120 in the horizontal direction, so that the support plate 120 can only slide up and down along the axial direction of the positioning post 112. The positioning column 112 and the positioning groove 121 serve as guides and positions, ensuring that the support plate 120 maintains the correct position and orientation when sliding vertically relative to the base plate 110, without any deviation or shaking, thus ensuring the stability and accuracy of the entire device structure.

[0036] In some embodiments of this utility model, a plurality of card holders 122 are provided on the upper end of the support plate 120, and the plurality of card holders 122 are evenly distributed around the center of gravity of the support plate 120; the card holders 122 are provided with arc-shaped surfaces 123 corresponding to the lower circumference of the storage cylinder 400. Specifically, in this embodiment, a plurality of card holders 122 are provided on the upper end of the support plate 120, evenly distributed around its center of gravity. This layout is based on considerations of mechanical balance and stability. When the storage cylinder 400 is placed on the support plate 120, the plurality of card holders 122 together provide support for the cylinder. Because they are evenly distributed around the center of gravity of the support plate 120, the weight of the cylinder can be distributed more evenly on the support plate 120, avoiding excessive local pressure. Each card holder 122 is provided with an arc-shaped surface 123 corresponding to the lower circumference of the storage cylinder 400, and the plurality of such card holders 122 together form an arc-shaped groove. The arc-shaped surface 123 is adapted to the lower circumference of the cylinder and can fit tightly against the surface of the cylinder. This not only allows for better positioning of the cylinder, ensuring its stable position on the support plate 120, but also provides restraint for the cylinder when it is subjected to external forces, such as slight vibrations during filling, preventing it from rolling or shifting on the support plate 120 and ensuring its stability during filling.

[0037] In some embodiments of this utility model, the fixed bracket 200 includes two support components 220, which are respectively disposed on both sides of the support plate 120. Each support component 220 includes a vertical rod 221 and connecting blocks 222 disposed on the upper and lower sides of the vertical rod 221. The lower end of the vertical rod 221 is fixed to the support plate 120 through the connecting blocks 222. Specifically, in this embodiment, the fixed bracket 200 is composed of two support components 220, which are respectively located on both sides of the support plate 120. Each support component 220 includes a vertical rod 221 and connecting blocks 222 disposed on the upper and lower sides of the vertical rod 221. The vertical rod 221, as the main support component, bears the weight from the upper filling mechanism 300 and related components, and transfers it to the lower support plate 120. The connecting blocks 222 connect the vertical rod 221 and the support plate 120, ensuring that the entire fixed bracket 200 and the support plate 120 form a stable integral structure by firmly connecting the lower end of the vertical rod 221 to the support plate 120. This structural design allows the fixed bracket 200 to effectively support components such as the filling mechanism 300, ensuring the stability of the device during the filling process. Two support components 220 are symmetrically arranged on both sides of the support plate 120; this symmetrical layout helps maintain the balance of the entire device. During the filling process, external forces, whether from the filling mechanism 300 or minor vibrations that may occur in the storage cylinder 400 during filling, can be evenly distributed onto the support plate 120 through the symmetrical support components 220, preventing the device from tilting or shaking due to uneven force distribution, further enhancing the stability and reliability of the device.

[0038] In some embodiments of this utility model, the fastening assembly 210 includes an adjusting block 212, a guide rod 213, and a drive rod 214. The adjusting block 212 and the upright rod 221 are slidably connected; the guide rod 213 and the adjusting block 212 are slidably connected, one end of the guide rod 213 passes through the adjusting block 212 and is fixedly connected to the push plate 211, and the drive rod 214 is threadedly connected to the adjusting block 212, one end of the drive rod 214 passes through the adjusting block 212 and is rotatably connected to the push plate 211. Specifically, in this embodiment, the guide rod 213 is slidably connected to the adjusting block 212, and one end of the guide rod 213 is fixedly connected to the push plate 211. The guide rod 213 guides the movement direction of the adjusting block 212, ensuring that the movement of the adjusting block 212 can accurately drive the push plate 211 to make corresponding displacements. At the same time, the guide rod 213 ensures the stability of the push plate 211 during movement, so that it can only move along the axial direction of the guide rod 213, avoiding shaking or deviation. The drive rod 214 is threadedly connected to the adjusting block 212, and one end of the drive rod 214 passes through the adjusting block 212 and is rotatably connected to the push plate 211. When the drive rod 214 is rotated, due to the characteristics of the threaded connection, the rotational motion of the drive rod 214 is converted into the linear motion of the adjusting block 212 along the upright 221. By controlling the rotation direction and number of rotations of the drive rod 214, the position of the adjusting block 212 on the upright 221 can be precisely controlled, thereby accurately adjusting the position of the push plate 211 to meet the fastening requirements of storage cylinders 400 of different sizes.

[0039] In some embodiments of this invention, a handwheel 215 is provided on one side of the drive rod 214. Specifically, in this embodiment, the operator only needs to hold and turn the handwheel 215 to easily control the rotation of the drive rod 214, thereby adjusting the position of the push plate 211 to tighten or loosen the storage cylinder 400. No additional tools are required, simplifying the operation process and saving operation time. Especially when the position of the push plate 211 needs frequent adjustment, it greatly improves work efficiency.

[0040] In some embodiments of this utility model, the upright 221 is provided with a plurality of limiting holes 2211 along the axial direction, and the adjusting block 212 is fixed to the limiting holes 2211 by a positioning pin 223. Specifically, in this embodiment, the upright 221 is provided with a plurality of limiting holes 2211 along the axial direction, and these limiting holes 2211 provide a series of definite position selections for the adjusting block 212. After the adjusting block 212 slides to a suitable position on the upright 221, it is fixed by inserting the positioning pin 223 into the limiting hole 2211. The positioning pin 223 and the limiting hole 2211 have a high fitting precision. When the positioning pin 223 is inserted into the corresponding limiting hole 2211, the axial position of the adjusting block 212 on the upright 221 is locked and cannot slide freely, thereby accurately determining the position of the adjusting block 212 on the upright 221.

[0041] In some embodiments of this utility model, the push plate 211 is arched, and an elastic layer is provided on the concave surface of the push plate 211. Specifically, in this embodiment, an elastic layer is provided on the concave surface of the push plate 211, and the elastic layer is generally made of an elastic material, such as rubber. When the cylinder contacts the push plate 211, the elastic layer plays a role in buffering and conforming. On the one hand, it can buffer the impact force between the cylinder and the push plate 211, avoiding damage to the cylinder surface caused by rigid collision, and also reducing the noise generated by the collision. On the other hand, the elastic layer can deform to a certain extent according to the shape of the cylinder, better conforming to the cylinder surface, increasing the contact area with the cylinder, thereby improving the fixing effect of the cylinder and making the cylinder more stable during the filling process.

[0042] In some embodiments of this utility model, the filling mechanism 300 includes an air inlet pipe 320, one end of which is connected to the filling head 310. A pressure gauge 330 is installed on the air inlet pipe 320. Specifically, in this embodiment, the pressure gauge 330 is installed on the air inlet pipe 320 and senses the pressure change of the gas inside the air inlet pipe 320 through an internal pressure sensing element. When the gas pressure inside the air inlet pipe 320 changes, the pressure sensing element will generate a corresponding deformation or electrical signal change. After conversion and processing by the internal conversion mechanism of the pressure gauge 330, the pressure value is displayed on the dial in a visually intuitive numerical form. The operator can observe the reading of the pressure gauge 330 in real time to understand the pressure of the gas inside the air inlet pipe 320, so as to adjust various parameters in the filling process in a timely manner and ensure the safety and accuracy of the filling operation.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
