Description

Technical Field

[0001] This utility model relates to the technical field of gas distribution stations, and in particular to a multi-channel gas distribution station for controlled atmosphere storage. Background Technology

[0002] Controlled atmosphere storage, also known as controlled atmosphere storage, is the most advanced method for preserving and storing fruits and vegetables. A gas distribution mechanism is an auxiliary device used in warehousing and logistics processes to rapidly distribute different gases required by storage equipment, thereby improving storage quality. Existing technology announcement CN216046898U discloses a gas distribution mechanism including a bottom pipe, a vertical pipe, a first gas pipe, a first support rod, a first gas box, a first cylinder, a first piston, a second gas pipe, a second support rod, a second gas box, a second cylinder, a second piston, a fixed frame, a pressure gauge, and a drain pipe. The vertical pipe is fixedly installed at the top of the bottom pipe, the first gas pipe is inserted into the bottom pipe from the vertical pipe, the first support rod is fixedly installed at the top of the bottom pipe, and the first gas box is fixedly installed at the top of the first support rod. However, when it is necessary to replace the gas in the gas box with another type of gas, the conical cap prevents the piston from reaching the bottom of the gas box to completely expel the original air. This causes the new type of gas to mix with the original gas when it is stored in the gas box, resulting in impure gas. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a multi-channel gas distribution station for controlled atmosphere storage that can completely expel the air in the gas chamber, facilitate gas replacement, and avoid gas mixing.

[0004] This utility model discloses a multi-channel gas distribution station for controlled atmosphere storage, comprising a gas box, a base plate, a base, an exhaust pipe, a pushing component, a guiding component, a water outlet component, and a sealing component. The gas box is installed on top of the base plate, and the bottom of the base plate is installed on top of the base. The exhaust pipe has multiple gas chambers inside, with the inlet end of the exhaust pipe communicating with the gas chambers. The exhaust pipe is installed at the front end of the base, and the outlet end of the exhaust pipe passes through the base. The pushing component is installed on top of the gas box, with its outlet end located inside the gas chamber. A guiding component is installed on the pushing component. The sealing component is installed at the bottom of the gas chamber, above the inlet end of the exhaust pipe. A water outlet component is installed at the lower part of the gas chamber. The multiple gas chambers effectively isolate different gases, preventing gas mixing and enhancing the overall integrity of the equipment. The pushing component allows the air in the gas chambers to be completely discharged, facilitating gas replacement and preventing gas mixing. The sealing component seals the inlet end of the exhaust pipe after the gas is discharged. The water outlet component discharges condensate, preventing it from affecting gas distribution.

[0005] Preferably, the pushing assembly includes a chassis, an exhaust pipe, an electric telescopic rod, and a piston plate. The chassis is installed at the bottom of the air chamber, and a conical groove is formed on the top of the chassis. The exhaust pipe is installed in the middle of the conical groove, and the output end of the exhaust pipe is connected to the input end of the exhaust pipe. Multiple air holes are formed on the upper part of the exhaust pipe. The electric telescopic rod is installed on the top of the air box, and the telescopic end of the electric telescopic rod extends into the air chamber to install the piston plate. The lower part of the piston plate is conical, and a clearance slot matching the exhaust pipe is formed at the bottom of the piston plate. When it is necessary to exhaust the original gas inside the air chamber, the electric telescopic rod is activated to push the piston plate downward and squeeze it in the air chamber. The bottom of the piston plate contacts the chassis, and at this time, the exhaust pipe enters the clearance slot, so that the gas is completely discharged, which facilitates gas replacement and avoids gas mixing.

[0006] Preferably, the sealing component includes multiple support rods, a fixing ring, a push rod, a sealing cap, and a spring. The multiple support rods are installed at the lower end of the inner wall of the air outlet pipe, and a fixing ring is installed in the middle of the support rod. The push rod is slidably installed in the middle of the fixing ring, and the upper part of the push rod slides through the top of the air outlet pipe to install the sealing cap. The spring is fitted on the outer wall of the push rod, with the bottom of the spring connected to the top of the fixing ring and the top of the spring connected to the upper outer wall of the sealing cap. When the piston plate moves downward and contacts the chassis, it pushes the sealing cap downward, causing the push rod to slide on the fixing ring, compressing the spring, and causing the sealing cap to cover the upper part of the air outlet pipe to seal the air hole. After the piston plate moves upward, the sealing cap returns to its original position under the elastic force of the spring.

[0007] Preferably, the water outlet component includes a drain pipe, a solenoid valve, a level gauge, and a controller. The inlet end of the drain pipe is connected to the bottom of the conical groove of the chassis, and a solenoid valve is installed on the drain pipe. The outlet end of the drain pipe extends out of the air chamber. The level gauge is installed inside the chassis, and the level gauge is lower than the height of the air hole. The controller is installed on the outer wall of the air chamber. After the level gauge detects condensate, it controls the solenoid valve to open so that the condensate is discharged outward through the drain pipe, thus avoiding affecting the gas distribution.

[0008] Preferably, the guiding component includes multiple guide frames and multiple I-shaped guide rods. The guide frames are symmetrically installed on the top of the air box about the electric telescopic rod. An I-shaped guide groove is opened inside the guide frame. The I-shaped guide rod is slidably installed in the guide groove. The bottom of the I-shaped guide rod is connected to the top of the piston plate. When the piston plate moves downward, it drives the I-shaped guide rod to slide in the I-shaped guide groove of the guide frame, which limits and guides it, enhances the structural strength, and ensures stability.

[0009] Preferably, it also includes a wiper strip, and an installation groove is provided on the outer wall of the piston plate, in which the wiper strip is installed; when the piston plate moves, it drives the wiper strip to scrape the inner wall of the air chamber to ensure drainage effect.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the multiple air chambers can effectively isolate different gases, effectively prevent gas mixing, and enhance the overall integrity of the equipment. The pushing component can completely discharge the air in the air chamber, which is convenient for gas replacement and avoids gas mixing. The sealing component can seal the inlet end of the exhaust pipe after the gas is discharged. The water outlet component can discharge condensate water to avoid affecting gas distribution.

[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0018] like Figures 1 to 5As shown, the air box 1 is installed on top of the base plate 2, and the bottom of the base plate 2 is installed on top of the base 3. Multiple air chambers are opened inside the exhaust pipe 4. The input end of the exhaust pipe 4 communicates with the interior of the air chambers. The exhaust pipe 4 is installed at the front end of the base 3, and the output end of the exhaust pipe 4 passes through the base 3. The chassis 5 is installed at the lower part of the air chambers. A conical groove is opened on the top of the chassis 5. The exhaust pipe 6 is installed in the middle of the conical groove, and the output end of the exhaust pipe 6 is connected to the input end of the exhaust pipe 4. Multiple air holes are opened on the upper part of the exhaust pipe 6. An electric telescopic rod 7 is installed on top of the air box 1. The telescopic end of the electric telescopic rod 7 extends into the air chamber and is fitted with a piston plate 8. The lower part of the piston plate 8 is conical, and the bottom of the piston plate 8 has a clearance slot that matches the exhaust pipe 6. Multiple support rods 9 are installed on the lower end of the inner wall of the exhaust pipe 6. A fixing ring 10 is installed in the middle of the support rod 9, and a push rod 11 is slidably installed in the middle of the fixing ring 10. The upper part of the push rod 11 slides through the top of the air outlet pipe 6 and is equipped with a sealing cover 12. The spring 13 is fitted on the outer wall of the push rod 11. The bottom of the spring 13 is connected to the top of the fixing ring 10. The top of the spring 13 is connected to the upper outer wall of the sealing cover 12. The input end of the drain pipe 14 is connected to the bottom of the conical groove of the chassis 5. The drain pipe 14 is equipped with a solenoid valve 15. The output end of the drain pipe 14 extends out of the air chamber. The liquid level detector 16 is installed in the chassis 5. The liquid level detector 16 is lower than the height of the air hole. The controller 17 is installed on the outer wall of the air box 1. The guide frame 18 is symmetrically installed on the top of the air box 1 about the electric telescopic rod 7. The guide frame 18 has an I-shaped guide groove inside. The I-shaped guide rod 19 is slidably installed in the guide groove. The bottom of the I-shaped guide rod 19 is connected to the top of the piston plate 8. The piston plate 8 has an installation groove on its outer wall. The wiper strip 20 is installed in the installation groove.

[0019] When it is necessary to purge the original gas inside the air chamber, the electric telescopic rod 7 is activated to push the piston plate 8 downward within the air chamber, until the bottom of the piston plate 8 contacts the chassis 5. At this time, the vent pipe 6 enters the clearance slot, allowing the gas to be completely discharged, facilitating gas replacement and preventing gas mixing. When the piston plate 8 moves downward and contacts the chassis 5, it pushes the sealing cover 12 downward, causing the push rod 11 to slide on the fixing ring 10, compressing the spring 13, so that the sealing cover 12 covers the upper part of the vent pipe 6, sealing the vent. After the piston plate 8 moves upward, the sealing cover 12 returns to its original position under the elastic force of the spring 13. After the liquid level gauge 16 detects condensate, it controls the solenoid valve 15 to open, allowing the condensate to be discharged outward through the drain pipe 14, avoiding affecting gas distribution. When the piston plate 8 moves downward, it drives the I-shaped guide rod 19 to slide in the I-shaped guide groove of the guide frame 18, limiting and guiding it, enhancing structural strength, and ensuring stability. When the piston plate 8 moves, it drives the scraper strip 20 to scrape the inner wall of the air chamber, ensuring drainage effect.

[0020] like Figures 1 to 5As shown, this utility model discloses a multi-channel gas distribution station for a controlled atmosphere storage facility. During operation, when the original gas inside the air chamber needs to be vented, the electric telescopic rod 7 is activated to push the piston plate 8 downwards within the air chamber. As the piston plate 8 moves downwards, it causes the I-shaped guide rod 19 to slide within the I-shaped guide groove of the guide frame 18, providing limiting and guiding. The bottom of the piston plate 8 contacts the chassis 5, at which point the outlet pipe 6 enters the clearance slot, allowing the gas to be completely vented, facilitating gas replacement. The piston plate 8 moves downwards and contacts the chassis 5. When the disc 5 contacts, it pushes the sealing cover 12 downward, causing the push rod 11 to slide on the fixing ring 10, compressing the spring 13, so that the sealing cover 12 covers the upper part of the air outlet pipe 6, sealing the air hole. After the piston plate 8 moves upward, the sealing cover 12 returns to its original position under the elastic force of the spring 13. When the piston plate 8 moves, it drives the scraper strip 20 to scrape the inner wall of the air chamber. After the liquid level detector 16 detects the condensate, it controls the solenoid valve 15 to open so that the condensate can be discharged outward through the drain pipe 14 to avoid affecting the gas distribution.

[0021] The solenoid valve 15, liquid level gauge 16, and controller 17 of this utility model for a multi-channel gas distribution station in a controlled atmosphere storage facility are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
