Description

Technical Field

[0001] This utility model belongs to the field of nitrogen bag cleaning technology, and specifically relates to a tower-type nitrogen bag cleaning device. Background Technology

[0002] Nitrogen bags, as the name suggests, are packaging bags filled with nitrogen gas. Their main function is to create a high-purity nitrogen environment inside the bag and eliminate air and oxygen. Nitrogen is inert and does not readily participate in chemical reactions, thus effectively preventing products from being affected by oxidation, spoilage, deterioration, or microbial growth. This is crucial for maintaining product freshness and safety. Tower-type nitrogen bag cleaning devices employ a structural design similar to nitrogen scrubbing towers, where gas passes through the tower and comes into full contact with the washing liquid or cleaning medium, thereby removing impurities and odors from the nitrogen bag.

[0003] Currently, the number of inflation tubes in tower-type nitrogen bag cleaning devices on the market is fixed. When the size, shape, or cleaning requirements of the nitrogen bag change, the number of inflation tubes cannot be adjusted. As a result, the device may not be able to adapt to these changes, leading to poor cleaning effect or failure to complete the cleaning task. Moreover, the fixed number of inflation tubes may make it inconvenient for operators to handle nitrogen bags of different sizes or shapes, increasing the complexity of operation and time costs. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a tower-type nitrogen bag cleaning device to solve the problem that when the size, shape or cleaning requirements of the nitrogen bag change, the number of inflation tubes cannot be adjusted, so the device may not be able to adapt to these changes, resulting in poor cleaning effect or failure to complete the cleaning task. Moreover, a fixed number of inflation tubes may make it inconvenient for operators to handle nitrogen bags of different sizes or shapes, increasing the complexity of operation and time costs.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A tower-type nitrogen bag cleaning device includes a nitrogen tower body and a vacuum pump. An inlet pipe is fixedly connected to the upper end of the nitrogen tower body, and an outlet pipe is fixedly connected to the outer wall of the nitrogen tower body. A flow controller is fixedly connected to the other end of the outlet pipe. An installation groove is opened at one end of both the flow controller and the vacuum pump. A fixing pipe is fixedly connected inside the installation groove. A connecting seat is provided at one end of the flow controller body. A connecting hose is fixedly connected to both ends of the connecting seat. An installation seat is fixedly connected to the other end of the connecting hose. The installation seat is movably connected to the flow controller and the vacuum pump respectively. An inflation pipe is symmetrically fixedly connected to the other end of the connecting seat. An inflation head is fixedly connected to the other end of the inflation pipe. A connecting block is symmetrically fixedly connected to the outer wall of the installation seat. A fixing component is installed inside the connecting block. A positioning component is symmetrically installed on the outer wall of the installation seat.

[0007] The fixing assembly includes a cavity, a first return spring, a movable plate, a push block, and a locking block. The connecting block has a cavity inside, and the first return spring is symmetrically fixedly connected to one end of the cavity. The movable plate is fixedly connected to the other end of the first return spring. The movable plate is slidably connected to the cavity. The push block and the locking block are fixedly connected to the end of the movable plate away from the first return spring. The push block and the locking block extend from the side end of the connecting block at the ends away from the movable plate. The inner wall of the mounting groove has symmetrical connecting grooves. The connecting grooves are inserted into the connecting block. The inner wall of the connecting groove has a locking groove at one end. The locking groove is locked into the locking block. This ensures that nitrogen can be evenly filled into nitrogen bags of different sizes and shapes, making the cleaning device suitable for nitrogen bags of various specifications.

[0008] As a preferred technical solution, the outer wall of the mounting base is symmetrically fixed with positioning sliders via an annular circumferential array, and the inner wall of the mounting groove is symmetrically provided with positioning grooves. The positioning grooves and positioning sliders are plugged in, the mounting base and the mounting groove are plugged in, and the fixing tube is plugged in to the inside of the mounting base. The design of the positioning sliders and positioning grooves can effectively fix the connection between the hose and the flow controller and vacuum pump, preventing the connection from loosening or falling off due to airflow impact or equipment vibration during the cleaning process.

[0009] As a preferred technical solution, the end of the mounting base away from the connecting hose is symmetrically fixed with a fixing post through a circular circumferential array. One end of the mounting groove is symmetrically provided with fixing holes through a circular circumferential array. The fixing post and the fixing hole are plugged in. The design of the positioning post and the positioning hole can ensure the accurate positioning and connection between the connecting hose and the flow controller and vacuum pump.

[0010] As a preferred technical solution, the positioning component includes an internal hole, a second return spring, and a positioning post. The external wall of the mounting base has symmetrical internal holes. One end of the internal hole is fixedly connected to the second return spring, and the other end of the second return spring is fixedly connected to the positioning post. The positioning post is slidably connected to the internal hole. The end of the positioning post away from the second return spring extends out of the external wall of the mounting base and is set as an arc surface. The inner wall of the mounting groove has symmetrical positioning holes. The positioning holes and the positioning posts are snap-fitted together, which improves the overall stability of the equipment and ensures the continuity and stability of nitrogen during the transmission process, providing a reliable guarantee for the cleaning process.

[0011] As a preferred technical solution, a sealing gasket is fixedly connected to the inner wall of the mounting groove, and the other end of the sealing gasket is in contact with the outer wall of the mounting base, which can ensure a tight connection between the mounting groove and the mounting base and prevent nitrogen leakage.

[0012] In summary, the present invention has the following main advantages:

[0013] In this invention, pressing the button causes the moving plate to move the locking block. The moving plate presses against the first return spring, compressing the spring and causing the locking block to retract into the cavity. Then, the connecting hoses at both ends of the connecting seat are connected to one end of the flow controller and the vacuum pump, respectively, so that the mounting seat is inserted into the mounting groove. Simultaneously, the connecting block is inserted into the connecting groove, the fixing post is inserted into the fixing hole, and the positioning slider is inserted into the positioning groove. Then, the button is released, the first return spring returns to its original position, the moving plate rebounds, and the locking block pops out. The locking block pops out and engages with the slot, completing the installation of the inflation tube, flow controller, and vacuum pump. By adjusting the number of inflation tubes, nitrogen can be evenly filled into nitrogen bags of different sizes and shapes, making the cleaning device suitable for nitrogen bags of various specifications without the need to change equipment or make complex adjustments. Moreover, adjusting the number of inflation tubes according to the actual needs of the nitrogen bag can avoid unnecessary nitrogen waste, help reduce cleaning costs, and reduce environmental impact.

The inner wall of the mounting groove 5 has symmetrically formed connecting grooves 18, which are inserted into the connecting block 17. One end of the inner wall of the connecting groove 18 is open... A slot 20 is provided, which is engaged with the locking block 195. Pressing the button 194 causes the moving plate 193 to move the locking block 195. The moving plate 193 presses against the first return spring 192, which is compressed. At the same time, the locking block 195 retracts into the cavity 191. Then, the connecting hoses 8 at both ends of the connecting seat 9 are connected to one end of the flow controller 4 and the vacuum pump 12, respectively, so that the mounting seat 7 is inserted into the mounting groove 5. At the same time, the connecting block 17 is inserted into the connecting groove 18. Then, the button 194 is released, the first return spring 192 is reset, the moving plate 193 rebounds and causes the locking block 195 to pop out. The locking block 195 pops out and engages with the slot 20 to fix it, thus completing the installation of the inflation tube 10 with the flow controller 4 and the vacuum pump 12.

[0023] refer to Figures 2 to 3 The outer wall of the mounting base 7 is symmetrically fixed with positioning sliders 13 via an annular circumferential array.

The connecting hoses 8 at both ends of the connecting base 9 are connected to one end of the flow controller 4 and the vacuum pump 12 respectively, so that the mounting base 7 is inserted into the interior of the mounting groove 5. At the same time, the positioning sliders 13 are inserted into the positioning grooves 14.

One end of the internal hole 211 is fixedly connected to the second return spring 212, and the other end of the second return spring 212 is fixedly connected to the positioning post 213. The positioning post 213 is slidably connected to the internal hole 211. The end of the positioning post 213 away from the second return spring 212 extends out of the outer side wall of the mounting base 7 and is designed as an arc surface. The mounting groove 5 has symmetrically arranged positioning holes 22 on its inner wall. The positioning holes 22 and the positioning posts 213 are interlocked.

The other end of the sealing gasket 23 is in contact with the outer wall of the mounting base 7. The sealing gasket 23 ensures a tight connection between the mounting groove 5 and the mounting base 7, preventing nitrogen leakage.

[0027] Operating principle and advantages: First, press the button 194 to move the moving plate 193, which in turn moves the locking block 195. The moving plate 193 presses against the first return spring 192, compressing the first return spring 192. Simultaneously, the locking block 195 retracts into the cavity 191. Then, the connecting hoses 8 at both ends of the connecting seat 9 are connected to one end of the flow controller 4 and the vacuum pump 12, respectively, so that the mounting seat 7 is inserted into the mounting groove 5. During the insertion process, the squeezing force applies pressure to the arc-shaped surface of the positioning post 213, causing the positioning post 213 to compress the second return spring 212. The positioning post 213 retracts into the internal hole 211. Then, when the positioning post 213 moves to the positioning hole 22, the second return spring 212 resets, and the positioning post 213 pops out, and the positioning post 213 retracts into the internal hole 211. The mounting hole 22 is snapped in place to fix the mounting base 7 and the mounting groove 5. At the same time, the connecting block 17 is inserted into the connecting groove 18, the fixing column 15 is inserted into the fixing hole 16, and the positioning slider 13 is inserted into the positioning groove 14. Then, the button 194 is released, the first reset spring 192 is reset, the moving plate 193 rebounds and drives the locking block 195 to pop out. The locking block 195 pops out and snaps in place with the locking groove 20 to fix the gas filling pipe 10, the flow controller 4 and the vacuum pump 12 are installed. Then, the gas filling head 11 at one end of the gas filling pipe 10 is connected to the nitrogen bag. The flow controller 4 is started to fill the nitrogen bag with nitrogen from the nitrogen tower body 1. At the same time, the vacuum pump 12 is started to extract the nitrogen from the nitrogen bag. This process is repeated to clean the nitrogen bag.

[0028] This invention ensures that nitrogen can be uniformly filled into nitrogen bags of different sizes and shapes, making the cleaning device applicable to nitrogen bags of various specifications without the need to change equipment or make complex adjustments. Moreover, by adjusting the number of filling tubes 10 according to the actual needs of the nitrogen bags, unnecessary nitrogen waste can be avoided, which helps to reduce cleaning costs and reduce environmental impact.
