Description

Technical Field

[0001] The present invention relates to the technical field of tent sealing, and in particular to a tent sealing strip and a tent sealing assembly using the tent sealing strip. Background Art

[0002] Tobacco storage often requires the use of low-oxygen conditioning technology, which involves filling a sealed tobacco stack with nitrogen and maintaining the seal for a period of time to prevent pests. Currently, this sealing method involves laying a plastic film underneath and covering the stack with a plastic film. A rubber strip, fitted into a plastic trough, seals the outer edges of the two plastic films stacked between the plastic trough and the rubber strip.

[0003] See also Figure 1 and Figure 2 However, the existing rubber strips used in conjunction with the plastic tube 3 experience stress concentration. After 20-30 days of use, the sealing effect of the rubber strips and the plastic tube 3 on the plastic film begins to decline to varying degrees, until it reaches the lower limit of the acceptable sealing effect range. A complete sealing cycle for insecticides using low-oxygen conditioning technology generally lasts 50-60 days. As the airtightness continues to decline, the internal space of the plastic film needs to be filled with nitrogen more frequently to ensure the insecticide effect. This is not only time-consuming and labor-intensive, but also adds additional nitrogen filling costs. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a tent sealing strip that can slow down the decay of sealing performance in the installed state.

[0005] The present invention adopts the following technical solutions:

[0006] The present invention provides a tent sealing strip, comprising a strip hose main body and an indicator strip. The strip hose main body is a hose with a D-shaped cross-section structure. Two indicator strips are respectively arranged on both sides of a flat portion outside the strip hose main body, and the two indicator strips extend along the length direction of the strip hose main body. When the strip hose main body is in a natural state, the ends of the two indicator strips abut against each other.

[0007] Preferably, the strip hose body and the indicator strips are both black, and the outer plane portion of the strip hose body and the sides of the two indicator strips facing the outer plane portions of the strip hose body are coated with a white coating.

[0008] Preferably, the strip-shaped hose body and the indicator strip are both made of rubber.

[0009] The present invention also provides a tent sealing assembly, including a strip groove tube and the above-mentioned tent sealing strip, the flat part of the tent sealing strip is upwardly clamped in the groove of the strip groove tube, the arc-shaped outer wall of the strip hose body is evenly fitted with the interior of the groove, and the ends of the two indicator strips are against each other.

[0010] Preferably, the strip-shaped grooved tube is made of plastic.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] Compared with the original rubber strip, the tent sealing strip of the present invention changes the original O-shaped cross-sectional structure into a D-shaped structure. When it is installed in conjunction with the plastic groove tube, the flat part of the outer surface of the strip hose body is located at the top, thereby avoiding the stress concentration between the upper semicircular part of the original O-shaped cross-sectional structure and the plastic groove tube, making the stress distribution on the tent sealing strip more uniform, and making the sealing performance of the tent sealing strip in the installed state decay more slowly; at the same time, since the tent sealing strip is subjected to relatively uniform force after being installed in conjunction with the plastic groove tube, if the tent sealing strip is normally engaged with the plastic groove tube, the two indicator strips will remain in a natural state. When there is a problem with the engagement between the tent sealing strip and the plastic groove tube, resulting in incomplete sealing, the tent sealing strip will be subjected to uneven force, causing the ends of the two indicator strips to move away from each other, thereby reminding the operator to reseal the failed sealing part.

[0013] The tent sealing assembly of the present invention naturally has the above-mentioned beneficial effects because it adopts the above-mentioned tent sealing strips. Therefore, using the tent sealing assembly of the present invention in combination with plastic film to carry out low-oxygen controlled atmosphere pest control for tobacco storage piles can ensure that the airtightness of the entire controlled atmosphere maintenance cycle has no obvious attenuation and reduce the number of air replenishment times; at the same time, it can also promptly prompt the parts that are not completely sealed and the situation of unsealing during the controlled atmosphere process.

[0028] The following is a further detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. These embodiments are only used to illustrate the present invention and are not intended to limit the present invention.

[0029] In the description of the present invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0031] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0032] See also Figure 3 and Figure 4 This embodiment provides a tent sealing strip, including a strip hose main body 1 and an indicator strip 2. The strip hose main body 1 is a hose with a D-shaped cross-section structure. Two indicator strips 2 are respectively arranged on both sides of a flat portion 11 outside the strip hose main body 1, and the two indicator strips 2 extend along the length direction of the strip hose main body 1. When the strip hose main body 1 is in a natural state, the ends of the two indicator strips 2 abut against each other.

[0033] Compared with the original rubber strip, the tent sealing strip of this embodiment changes the original O-shaped cross-section structure to a D-shaped one. When it is installed with the plastic groove tube 3, the flat portion 11 on the outside of the strip hose body 1 is located at the top, thereby avoiding the stress concentration between the upper semicircular portion of the original O-shaped cross-section structure and the plastic groove tube 3, making the stress distribution on the tent sealing strip more uniform, and making the sealing performance of the tent sealing strip in the installed state decay slower; at the same time, combined with Figure 5 and Figure 6 Since the tent sealing strip and the plastic groove tube 3 are installed with relatively uniform force, if the tent sealing strip and the plastic groove tube 3 are normally fitted together, the two indicator strips 2 will remain in a natural state. However, when there is a problem with the fitting between the tent sealing strip and the plastic groove tube 3, resulting in incomplete sealing, the tent sealing strip will be subjected to uneven force, causing the ends of the two indicator strips 2 to move away from each other, thereby reminding the operator to reseal the failed sealing part.

[0034] Preferably, the strip hose body 1 and the indicator strips 2 are both black, and the outer planar portion of the strip hose body 1 and the sides of the two indicator strips 2 facing the outer planar portion 11 of the strip hose body 1 are coated with a white coating.

[0035] When the tent sealing strip is not installed correctly, the ends of the two indicator strips 2 will move away from each other, exposing the white coating, which contrasts sharply with the black color of the strip hose main body 1 and the indicator strip 2 itself, significantly reducing the difficulty for the installer to notice the uninstalled parts; when the tent sealing strip is installed correctly, the ends of the two indicator strips 2 will abut against each other, the white coating is no longer visible, and only the black color of the strip hose main body 1 and the indicator strip 2 can be seen.

[0036] Preferably, the strip-shaped hose body 1 and the indicator strip 2 are both made of rubber.

[0037] See also Figures 3 to 5This embodiment also provides a tent sealing assembly, including a strip groove tube 4 and the above-mentioned tent sealing strip. The flat portion 11 of the tent sealing strip is upwardly clamped in the groove 41 of the strip groove tube 4. The arc-shaped outer wall of the strip hose body 1 is evenly fitted with the inside of the groove 41, and the ends of the two indicator strips 2 are against each other.

[0038] Since the tent sealing assembly of the present embodiment adopts the above-mentioned tent sealing strip, the use of the tent sealing assembly of the present embodiment in combination with a plastic film for low-oxygen controlled atmosphere pest control of tobacco storage piles can ensure that the airtightness of the entire controlled atmosphere maintenance cycle is not significantly attenuated, thereby reducing the number of air replenishment times; at the same time, it can also promptly provide phenomenon prompts for areas that are not completely sealed and for situations where the seal is unsealed during the controlled atmosphere process.

[0039] Preferably, the strip-shaped grooved tube 4 is made of plastic.

[0040] Specifically, in this embodiment, the test team used tent sealing strips and original rubber strips to fit into the grooved tubes to test the airtightness of two 200cm×200cm test stacks. The test parameters were as follows:

[0041] Test pile foot cargo stack parameters

[0042]

[0043] To verify the effectiveness, the test team conducted airtightness tests on two test stacks at the initial stage of sealing and 20 days after sealing, and drew a pressure half-life curve. The airtightness test data is summarized as follows:

[0044] Summary table of the half-life internal pressure of the test pile foot

[0045]

[0046] Combine Figure 7 As can be seen, after the initial sealing, the airtightness of test stacks A and B was essentially identical, with no significant difference. However, 20 days after sealing, the airtightness of test stack A, which used the original rubber strip, was -151 Pa at 150 seconds, compared to -190 Pa after the initial sealing, a difference of 25.8%. In contrast, the airtightness of test stack B, which used the tent sealing strip of this embodiment, was -194 Pa at 150 seconds, compared to -208 Pa after the initial sealing, a difference of 6.7%. Clearly, the use of the tent sealing strip of this embodiment significantly reduces the attenuation of airtightness, thereby reducing the number of air replenishments and improving nitrogen filling efficiency.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
