Description

Technical Field

[0001] This utility model relates to the field of gas filling technology, specifically to a multi-station independent control structure for a gas filling explosion-proof chamber. Background Technology

[0002] Gas cylinders require an explosion-proof filling chamber when being filled with gas. The explosion-proof chamber can separate the gas cylinder from the workers to prevent injury in the event of a gas cylinder explosion. However, existing explosion-proof chambers have certain shortcomings. They are simply constructed by setting up a chamber body without any protective mechanisms or mechanisms to increase the strength of the chamber body. This results in poor explosion-proof performance of the chamber body, and it cannot protect workers in the event of an explosion during filling.

[0003] Utility model patent CN217763015U discloses a skid-mounted gas filling explosion-proof chamber. This utility model includes a base, a chamber body on top of the base, and reinforcing ribs on the inner wall of the chamber body. Both the chamber body and the reinforcing ribs have through grooves, and explosion-proof windows are rotatably connected to the through grooves. The explosion-proof windows have through holes. A fixed plate and a cylinder are respectively provided on the inner wall of the reinforcing ribs. A sliding groove is provided in the fixed plate, and a movable plate is provided in the sliding groove, slidably connected to the sliding groove. This utility model, through the combined use of the protective plate, fixed plate, cylinder, sliding groove, movable plate, connecting spring, rotating rod, and air cushion, can improve the buffering performance of the chamber body, preventing damage to the chamber body during gas cylinder filling explosions. Simultaneously, the reinforcing ribs increase the strength of the chamber body, thus making it more explosion-proof and ensuring greater safety for workers filling gas cylinders.

[0004] While the aforementioned utility models can protect workers during gas cylinder filling, each model can only protect a single gas cylinder during filling, resulting in low filling efficiency. Therefore, we propose a multi-station independent control structure for gas filling explosion-proof chambers. Utility Model Content

[0005] This invention provides a multi-station independent control structure for a gas-filled explosion-proof chamber to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-station independent control structure for a gas filling explosion-proof chamber includes multiple parallel filling chambers, with a buffer chamber welded to the rear end of each filling chamber. Each filling chamber includes a filling chamber housing and a side door slidably connected to the front end of the filling chamber housing.

[0008] The filling chamber has a through cavity running from front to back. The front end of the upper surface of the filling chamber has an installation groove that penetrates the upper side wall of the filling chamber. The front ends of the left and right inner surfaces of the filling chamber have lifting grooves. The front end of the lower inner surface of the filling chamber has a sealing groove. The middle of the front and rear surfaces of the installation groove has notches.

[0009] As a preferred technical solution, the length of the mounting groove is less than the outer width of the front view of the filling chamber, the length of the mounting groove is greater than the inner width of the front view of the filling chamber, and the mounting groove, the lifting groove, and the sealing groove are all located on the same vertical plane.

[0010] This design, with its size limitation, ensures that the mounting slot neither exceeds the outer boundary of the enclosure (avoiding structural redundancy) nor covers the internal mating area (ensuring the stability of the side door sliding).

[0011] As a preferred technical solution, an observation window is installed at the upper end of the left side surface of the side door, and a through hole is opened on the side surface of the observation window. A handle is installed at the lower end of the left side surface of the side door, and a stop block is welded to the lower side of the left side surface of the side door. The side door is slidably connected to the lifting groove and the sealing groove through the mounting groove.

[0012] This feature allows for real-time monitoring of the filling process through the observation window, enabling observation of the internal condition without opening the side door, thus reducing operational risks.

[0013] As a preferred technical solution, the length of the stop block is greater than the length of the notch, and the length of the notch is greater than the diameter of the through hole.

[0014] This design, with its hierarchical size structure, ensures that the stop will be blocked by the notch when the side door moves upward, and the through hole can be adapted to the mounting pipe to avoid structural interference.

[0015] As a preferred technical solution, the buffer chamber includes a buffer chamber housing, several spring mechanisms installed at the four corners of the rear surface inside the buffer chamber housing, and a buffer plate fixedly installed at the front end of the spring mechanisms. Each of the four corners of the buffer plate has a connection hole for installing the spring mechanisms.

[0016] This design, combining the spring mechanism and the buffer plate to form a multi-layered buffer structure, can absorb the impact that may occur during the filling process and reduce the risk of explosion.

[0017] As a preferred technical solution, the spring mechanism includes a fixed sleeve welded to the rear surface inside the buffer chamber, a telescopic rod slidably connected to the inside of the right side of the fixed sleeve, and a connecting block welded to the right end of the telescopic rod, with a spring welded to the left end of the telescopic rod.

[0018] This design, with the sliding engagement of the telescopic rod and the fixed sleeve combined with the built-in spring, achieves a "telescopic-rebound" buffering logic, absorbing impact energy through spring deformation and improving the explosion-proof effect.

[0019] As a preferred technical solution, the connecting block is fixedly installed in the connecting hole, and the front surface of the connecting hole and the front surface of the buffer plate are located in the same vertical plane.

[0020] This design, with its coplanar layout, ensures that the front surface of the buffer plate is flat and fits more tightly with the filling chamber, reducing the risk of gas leakage or buffer failure caused by gaps.

[0021] As a preferred technical solution, the front surface of the buffer plate is in close contact with the rear surface of the filling chamber, a rubber sealing strip is provided on the contact surface between the buffer plate and the filling chamber, and damping oil is applied to the contact position between the fixing sleeve and the telescopic rod.

[0022] This feature uses damping oil to reduce sliding friction between the telescopic rod and the fixed sleeve, while also providing damping buffer to prevent severe vibrations when the spring rebounds, extending the service life of the buffer mechanism and improving explosion-proof stability.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. Multiple filling chambers are located at the front of a buffer chamber, which can protect workers during filling while allowing multiple workstations to fill simultaneously, thus improving filling efficiency.

[0025] 2. The rear side of the filling chamber is directly connected to the buffer chamber. When the buffer plate is pushed backward, the filling chambers can also be connected to each other, increasing the internal area and improving the buffering effect. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-6 This embodiment provides a technical solution:

[0037] The multi-station independent control structure of the gas filling explosion-proof chamber includes multiple parallel filling chambers 100, a buffer chamber 200 welded to the rear end of the filling chamber 100, and the filling chamber 100 includes a filling chamber box 110 and a side door 120 slidably connected to the front end of the filling chamber box 110.

[0038] The filling chamber housing 110 has a through cavity running from front to back. The front end of the upper surface of the filling chamber housing 110 has an installation groove 111 that penetrates the upper side wall of the filling chamber housing 110. The front ends of the left and right inner surfaces of the filling chamber housing 110 have lifting grooves 112. The front end of the lower inner surface of the filling chamber housing 110 has a sealing groove 113. The middle of the front and rear surfaces of the installation groove 111 has notches 114. Through the above mechanism, the operator can simultaneously operate multiple gas cylinders to perform filling operations under the protection of the explosion-proof chamber, which can effectively improve work efficiency.

[0039] Furthermore, such as Figure 3 As shown, the length of the mounting groove 111 is less than the outer width of the front view of the filling chamber box 110, and the length of the mounting groove 111 is greater than the inner width of the front view of the filling chamber box 110. The mounting groove 111, the lifting groove 112, and the sealing groove 113 are all located on the same vertical plane, ensuring that the side door 120 can be slidably connected between these grooves.

[0040] Furthermore, such as Figure 4As shown, an observation window 121 is installed on the upper part of the left side surface of the side door 120. A through hole 122 is opened on the side surface of the observation window 121. A handle 124 is installed on the lower part of the left side surface of the side door 120. A stop block 123 is welded to the lower side of the left side surface of the side door 120. The side door 120 is slidably connected to the lifting groove 112 and the sealing groove 113 through the mounting groove 111. One end of the handle 124 is cylindrical and the other end is flared, which makes it easy for users to grip.

[0041] In this embodiment, as Figure 2 As shown, the length of the stop 123 is greater than the length of the notch 114, and the length of the notch 114 is greater than the diameter of the through hole 122. The through hole 122 is used to place the inflation tube, and the notch 114 ensures that the inflation tube will not become an obstruction during the lifting and lowering of the side door 120.

[0042] In this embodiment, as Figure 5 As shown, the buffer chamber 200 includes a buffer chamber housing 210, several spring mechanisms 220 installed at the four corners of the rear surface inside the buffer chamber housing 210, and a buffer plate 230 fixedly installed at the front end of the spring mechanism 220. Each of the four corners of the buffer plate 230 has a connecting hole 240 for the spring mechanism 220 to be installed. A connecting block 221 is fixedly installed in the connecting hole 240. The front surface of the connecting hole 240 and the front surface of the buffer plate 230 are located in the same vertical plane. The buffer plate 230 is tightly attached to the rear surface of the filling chamber housing 110, blocking the rear side of the cavity through the filling chamber housing 110.

[0043] In this embodiment, as Figure 6 As shown, the spring mechanism 220 includes a fixed sleeve 223 welded to the rear surface inside the buffer chamber 210, a telescopic rod 222 slidably connected to the inside of the right side of the fixed sleeve 223, and a connecting block 221 welded to the right end of the telescopic rod 222. A spring 224 is welded to the left end of the telescopic rod 222.

[0044] In this embodiment, as Figure 5 As shown, the connecting block 221 is fixedly installed in the connecting hole 240. The front surface of the connecting hole 240 and the front surface of the buffer plate 230 are located in the same vertical plane. The front surface of the buffer plate 230 is in close contact with the rear surface of the filling chamber 110. A rubber sealing strip is provided on the contact surface between the buffer plate 230 and the filling chamber 110. Damping oil is applied to the contact position between the fixing sleeve 223 and the telescopic rod 222. The damping oil reduces the sliding friction between the telescopic rod 222 and the fixing sleeve 223, and at the same time provides damping buffer to avoid violent vibration when the spring 224 rebounds, extend the service life of the buffer mechanism, and improve the explosion-proof stability.

[0045] In the specific use of the multi-station independent control structure of the gas filling explosion-proof chamber in this embodiment, first hold the handle 124 and lift the side door 120 upward until the stop block 123 contacts the lower surface of the notch 114. Then, place the gas cylinder inside each filling chamber box 110. Next, pass the filling pipe through the through hole 122 and connect it to the gas cylinder. Then, close the side door 120 and wait for the gas cylinder to be filled.

[0046] If an accident causes the gas cylinder to explode, the resulting airflow will first impact the buffer plate 230. The buffer plate 230 will then move backward to compress the spring mechanism 220, thus mitigating the impact. After the buffer plate 230 moves backward, the internal cavities of the three filling chambers 110 will be connected, and the increased space area will also alleviate the compression caused by gas expansion.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
