Description

Technical Field

[0001] This utility model relates to the field of pest control technology, and in particular to a sealing structure for low-oxygen pest control in three-dimensional shelving stacks. Background Technology

[0002] Automated storage racks are a key component of modern warehousing and logistics. They use multi-layer racks to create a three-dimensional structure, making full use of vertical space and greatly increasing storage density. Goods are stored in each location in an orderly manner according to category and batch, making access convenient.

[0003] Automated storage racks significantly increase storage density through their multi-layered structure, but the close arrangement of goods can easily create hiding places for pests. Therefore, low-oxygen pest control treatment is required for the stacks. However, in the traditional low-oxygen pest control treatment process for automated storage racks, the sealing performance inside the sealed cover is poor, and the air inlet and outlet pipes are not easy to disassemble. Insufficient sealing performance will lead to continuous nitrogen leakage, causing the oxygen concentration to rise rapidly, which will prolong the pest control cycle. This not only increases nitrogen consumption, but also causes pests to feign death due to local oxygen concentration fluctuations, and subsequent resurgence will cause secondary pest infestations. At the same time, dust or insect eggs will accumulate inside the long-term fixed pipes, increasing the probability of cross-contamination. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1:

[0030] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a sealing structure for low-oxygen pest control in three-dimensional rack-type stacking positions, including a sealing cover 1, a rack body 2 is provided inside the sealing cover 1, a sealing component 3 is provided at the bottom of the sealing cover 1, and a disassembly component 4 is provided on one side of the sealing cover 1.

[0031] The sealing cover 1, as the core part of the entire sealing structure, is used to wrap the three-dimensional rack-type stack to form a relatively closed space for low-oxygen pest control treatment, preventing outside air from entering and affecting the pest control effect, while also preventing the pest control gas from leaking into the outside environment. It should be noted that the sealing cover 1 is made of high-strength, airtight materials, such as polyvinyl chloride (PVC) coated cloth and polyethylene (PE) film. These materials have good flexibility and corrosion resistance, can adapt to rack-type stacks of different shapes and sizes, and are not easily damaged during long-term use, ensuring the sealing effect. The rack body 2 uses multi-layer racks to stack goods to form a three-dimensional storage unit, saving space, adapting to low-oxygen pest control, and improving the efficiency of warehousing and pest control treatment.

[0032] The sealing assembly 3 includes a sealing strip 31 fixed to the bottom of the sealing cover 1, and two sets of sealing gaskets 32 are fixedly connected to the inner wall of the sealing cover 1.

[0033] The sealing strip 31 is fixed to the bottom of the sealing cover 1 and contacts the ground, which plays a preliminary sealing role, reduces the gap between the bottom of the sealing cover 1 and the ground, and prevents gas from leaking from the bottom. At the same time, both sets of sealing gaskets 32 are set on one side of the zipper teeth 13. When the zipper teeth 13 are pulled up by the zipper head 14, the two sets of sealing gaskets 32 are combined to seal the zipper teeth 13, enhance the sealing performance of the zipper teeth 13, prevent gas from leaking from the zipper, and ensure the stability of the low oxygen environment inside the sealing cover 1.

[0034] The disassembly assembly 4 includes a connecting pipe 41 that communicates with the inner wall of the sealing cover 1. A sleeve 42 is threadedly connected to the outer side of the connecting pipe 41, and an installation pipe 43 is threadedly connected to the inner wall of the sleeve 42.

[0035] The connecting pipe 41 is connected to the inner wall of the sealing cover 1, serving as a channel for gas to enter and exit the sealing cover 1. It is threadedly connected to the sleeve 42, facilitating disassembly and installation, and making it convenient for pipeline maintenance or replacement. The outer side of the sleeve 42 is threadedly connected to the connecting pipe 41, and the inner wall is threadedly connected to the installation pipe 43, serving as a connection and transition. The threaded connection enables the disassembly of the inlet pipe 5 and the outlet pipe 6, allowing operators to assemble and disassemble them according to actual needs. The inner wall of the installation pipe 43 is connected to the inlet pipe 5, and the threaded connection with the sleeve 42 facilitates the installation and disassembly of the inlet pipe 5, making it convenient for the gas supply system to be connected and disconnected. It should be noted that one end of the inlet pipe 5 is also equipped with a disassembly component 4, so the inlet pipe 5 can also be disassembled and installed.

[0036] Example 2:

[0037] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the inner wall of the mounting pipe 43 is connected to the air inlet pipe 5, and the air outlet pipe 6 is provided on one side of the sealing cover 1. The air outlet pipe 6 and the air inlet pipe 5 are designed symmetrically with respect to the center line of the sealing cover 1.

[0039] The air inlet pipe 5 is used to fill the sealed cover 1 with insecticidal gas, such as nitrogen and carbon dioxide. It is the channel for the gas to enter the sealed cover 1. The air outlet pipe 6 is designed symmetrically with the air inlet pipe 5 at the center line of the sealed cover 1. It is used to discharge the air or other gases in the sealed cover 1, maintain the low oxygen environment in the sealed cover 1, and ensure that the gas can flow smoothly to improve the insecticidal efficiency.

[0040] Specifically, a valve 7 for controlling gas flow is provided on the outside of the air intake pipe 5, and a first rubber pad 8 is fixedly connected to one end of the connecting pipe 41, and the outside of the first rubber pad 8 is inserted into the inner wall of the mounting pipe 43.

[0041] Valve 7 is located on the outside of the air inlet pipe 5 and is used to control the gas flow rate. The operator can adjust the opening of valve 7 according to actual needs to control the amount of gas entering the sealing cover 1, so as to ensure the stability and safety of the insecticidal process. It is noted that valve 7 is located on the outside of the air outlet pipe 6. The gas flow rate discharged from the air outlet pipe 6 can be controlled by adjusting valve 7. The first rubber gasket 8 is fixedly connected to one end of the connecting pipe 41, and its outer side is inserted into the inner wall of the installation pipe 43 to play a sealing role, preventing gas from leaking from the connection between the connecting pipe 41 and the installation pipe 43, and enhancing the sealing of the pipe connection.

[0042] Specifically, a second rubber pad 9 is fixedly connected to one end of the connecting pipe 41, and the outer side of the second rubber pad 9 is inserted into the inner wall of the mounting pipe 43. A sealing disc 10 for improving the sealing performance of the connecting pipe 41 is installed on the inner wall of the sealing cover 1, and the inner wall of the sealing disc 10 is connected to one end of the connecting pipe 41.

[0043] The second rubber pad 9 is fixedly connected to one end of the connecting pipe 41, and its outer side is inserted into the inner wall of the installation pipe 43, further enhancing the sealing effect between the connecting pipe 41 and the installation pipe 43, ensuring that the gas will not leak during pipeline transmission. The sealing plate 10 is mainly used to improve the sealing performance at the connection between the connecting pipe 41 and the sealing cover 1, preventing gas from leaking from the connection to the outside of the sealing cover 1, and ensuring a low-oxygen environment inside the sealing cover 1.

[0044] Example 3:

[0045] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0046] Specifically, multiple sets of connecting plates 11 are fixedly connected to the outer side of the sealing strip 31, and suction cups 12 for adsorbing onto the ground are fixedly connected to the bottom of each set of connecting plates 11.

[0047] Multiple sets of connecting plates 11 are fixedly connected to the outside of the sealing strip 31, serving as a connection and support for the installation of the suction cup 12. The suction cup 12 is fixedly connected to the bottom of the connecting plate 11 and is used to adhere to the ground, enhancing the adhesion between the sealing strip 31 at the bottom of the sealing cover 1 and the ground, preventing the sealing cover 1 from moving or shaking during gas filling or discharge, and further improving the sealing performance to prevent gas leakage.

[0048] Specifically, the inner wall of the sealing cover 1 is provided with zipper teeth 13, and a zipper head 14 is provided on one side of the zipper teeth 13.

[0049] Zipper teeth 13 are located on the inner wall of the sealing cover 1 and are used in conjunction with the zipper head 14 to open and close the sealing cover 1, facilitating personnel to enter and exit the sealing cover 1 for loading and unloading of goods. The zipper head 14 is located on one side of the zipper teeth 13. By pulling the zipper head 14, the zipper teeth 13 can be engaged or disengaged, thereby opening and closing the sealing cover 1.

[0050] Specifically, the inner wall of the sealing cover 1 is fixedly connected to the mounting frame 15, the inner wall of the mounting frame 15 is threadedly connected to the fixing bolt 16, and the outer side of the fixing bolt 16 is threadedly connected to the inner wall of the shelf body 2.

[0051] The mounting frame 15 is designed to provide an installation position for the fixing bolts 16, serving to connect and fix them. The fixing bolts 16 are designed to fix the edge of the sealing cover 1 to the shelf body 2, enhancing the reliability of the seal. The mounting frame 15 is made of metal, which has high strength and durability.

[0052] In use, first, cover the shelf body 2 with the sealing cover 1, with the sealing strip 31 in contact with the ground. Then, use the suction cup 12 to adhere to the ground, enhancing the bottom seal and preventing gas leakage from the bottom. Simultaneously, fix the edge of the sealing cover 1 to the shelf body 2 using the mounting frame 15 and fixing bolts 16 to further enhance sealing reliability. Then, manually pull the zipper head 14 to close the sealing cover 1 using the zipper teeth 13. The two sets of sealing gaskets 32 merge when the zipper closes, sealing the zipper teeth 13 and preventing gas leakage from the zipper. At this time, an external air pump connected to the air outlet pipe 6 evacuates the air from inside the sealing cover 1. Remove the original air from the sealed cover 1, then close the air outlet pipe 6 and its outer valve 7. Then connect an air inlet device to the air inlet pipe 5 to fill the sealed cover 1 with insecticidal gases such as nitrogen and carbon dioxide. Continuously monitor the gas composition and oxygen content in the sealed cover 1 to ensure a stable low-oxygen environment. The pests will die due to lack of oxygen. After the insecticidal process is completed, open the air outlet pipe 6 and valve 7 to release the low-oxygen gas. Then open the air inlet pipe 5 and valve 7 to fill in fresh air. Finally, remove the fixing bolt 16, and then insert a card-like object into the bottom of the suction cup 12 to lift the suction cup 12 and disassemble it. Finally, remove the sealed cover 1.
