Description

Technical Field

[0001] This utility model relates to a push-pull type vapor phase rust prevention control box, belonging to the field of rust prevention technology. Background Technology

[0002] Rust prevention is crucial during the storage, transportation, and protection of metal products. VCI vapor phase rust inhibitor is a substance that automatically releases rust-preventing gas molecules at room temperature. These gas molecules diffuse and adsorb onto all metal surfaces within a confined space, forming an adsorption protective layer. This effectively blocks moisture and oxygen from contacting the metal, achieving highly efficient rust prevention.

[0003] A vacuum-sealed VCI rust-proof bag, patent number CN208086468U, discloses a bag body, a top cover, and a shrink tube. The bag body has a pentahedral structure, consisting of a barrier and a box bottom welded to the bottom of the barrier. The top cover has a square structure, with one side fixed to the barrier and the other three sides being free sides. A connection port is provided in the middle of the top cover. The shrink tube is open at both ends, with one end connected to the connection port and the other end serving as a vacuum port. This method can completely replace the traditional VCI rust-proof bag + aluminum foil bag vacuum sealing method, satisfying multiple functions of dustproof, waterproof, and rustproof while reducing the use of aluminum foil bags and lowering costs.

[0004] When using the aforementioned VCI vapor phase rust inhibitor bags, the vapor phase rust inhibitor will continue to evaporate. Even after a rust-preventive protective film has formed on the metal surface, VCI molecules will continue to evaporate and adsorb onto the surfaces of other objects in the space. It is impossible to control the evaporation rate of the VCI vapor phase rust inhibitor according to the needs of the metal to be protected, thereby shortening the effective protection cycle of the VCI vapor phase rust inhibitor, easily causing waste of the VCI vapor phase rust inhibitor, and may also cause environmental pollution. At the same time, it is impossible to detect the usage of the VCI vapor phase rust inhibitor, making it difficult to replace the VCI vapor phase rust inhibitor in a timely manner, thus affecting the rust prevention effect. Utility Model Content

The bottom surface of the push-pull component is provided with a bidirectional memory alloy that expands and contracts with temperature changes. A hanging ring that can be detachably connected to a hook is provided on the side of the bidirectional memory alloy near the open structure.

[0007] Furthermore, the outer wall of the push-pull component away from the opening structure is provided with a battery compartment, a power switch, a function configuration module and a display screen, and the bottom surface of the push-pull component is provided with a weight sensor for detecting the weight of the rust inhibitor.

This effectively controls the volatilization rate of the VCI vapor phase rust inhibitor, extends the protection cycle of the VCI vapor phase rust inhibitor on the metal, and reduces the waste of raw materials and environmental pollution caused by the continuous volatilization of the VCI vapor phase rust inhibitor. Through the functional configuration module, display screen, and weight sensor, the consumption level of the VCI vapor phase rust inhibitor is monitored in real time based on the weight of the VCI vapor phase rust inhibitor, so as to facilitate timely replacement of the VCI vapor phase rust inhibitor and improve the rust prevention capability of the vapor phase rust prevention control box.

Detailed Implementation

[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0016] A push-pull vapor phase corrosion inhibitor control box, comprising: like Figure 1 As shown, the box body 1 has an open structure on one side. Multiple strip holes 101 are evenly distributed on the wall of the box body 1. A guide rail groove 102 is provided on the bottom surface of the box body 1. A hook 103 is provided on the side of the guide rail groove 102 away from the open structure. The box body 1 is made of HDPE material.

[0017] The push-pull component 2 is detachably connected to the box body 1. The dimensions of the push-pull component 2 match those of the box body 1. The side of the push-pull component 2 closest to the box body 1 has an open structure. The wall of the push-pull component 2 has multiple strip-shaped micro-membrane pores 201 that are staggered with the strip-shaped holes 101. The bottom surface of the push-pull component 2 is provided with a bidirectional memory alloy 202 that expands and contracts with temperature changes. The side of the bidirectional memory alloy 202 closest to the open structure is provided with a hanging ring 203 that is detachably connected to the hook 103. The push-pull component 2 is composed of an HDPE frame with a silicone coating and a microporous membrane material. Rollers 205 are provided on both outer walls of the push-pull component 2. The rollers 205 slide in contact with the guide rail grooves 102. The dimensions of the box body 1 and the push-pull component 2 are matched. The outer surface of the push-pull component 2 is provided with a silicone coating to ensure the sealing of the connection between the box body 1 and the push-pull component 2.

[0018] In this embodiment, the rust inhibitor installed in the push-pull component 2 is a VCI vapor phase rust inhibitor.

[0019] At room temperature, the bidirectional shape memory alloy 202 is in a stretched state, where the strip-shaped holes 101 and the strip-shaped micro-film holes 201 do not overlap, and the VCI vapor phase rust inhibitor volatilizes normally. Upon heating, the bidirectional shape memory alloy 202 contracts, pulling the push-pull component 2 along the guide groove 102. At this point, the strip-shaped holes 101 and the strip-shaped micro-film holes 201 overlap, thus slowing down the volatilization of the VCI vapor phase rust inhibitor. When the temperature drops, the bidirectional shape memory alloy 202 returns to its stretched state, pushing the push-pull component 2 along the guide groove 102. At this point, the strip-shaped holes 101 and the strip-shaped micro-film holes 201 do not overlap, and the VCI vapor phase rust inhibitor volatilizes normally. The deformation temperature of the bidirectional shape memory alloy can be set according to specific requirements.

[0020] Length of bidirectional shape memory alloy under tension satisfy: ; Length of bidirectional shape memory alloy in contracted state satisfy: ;in, The length of the box along the guide rail groove; The length of the push-pull component along the direction of the bidirectional shape memory alloy; This refers to the length of the hook.

[0021] In this embodiment, the front wall, rear wall, and top wall of the box body 1 are provided with multiple strip-shaped holes 101, with an open structure on the right side and a hole-free sealed structure on the bottom and left walls; the push-pull component 2 is slidably disposed inside the box body 1, and the wall of the push-pull component 2 is provided with multiple strip-shaped micro-membrane holes 201 at staggered positions corresponding to the strip-shaped holes 101 of the box body 1, with the side of the push-pull component 2 near the opening of the box body 1 being an open structure; by the relative movement of the push-pull component 2 and the box body 1, the alignment area between the strip-shaped holes 101 and the strip-shaped micro-membrane holes 201 can be changed.

[0022] The edges of the microporous membrane in the push-pull component can be welded or glued together.

[0023] The control system includes a battery compartment 6, a battery, a function configuration module, a display screen 5, a power switch 7, and a weight sensor 3 located on the outer wall of the push-pull component 2 away from the opening structure. The function configuration module includes an operation panel 4, an MCU (microcontroller unit), and a flash memory. The MCU is used to control various components in the control system, and the flash memory is used to store relevant data to prevent data loss after the battery is depleted. The operation panel 4 is equipped with multiple buttons, which are electrically connected to the MCU. By triggering the corresponding command through the button, the different functions of this device can be configured. The battery is located in the battery compartment 6, and the power switch 7 is connected in series in the power supply circuit formed by the battery and the MCU; Display screen 5 is electrically connected to the MCU and is powered by the power supply circuit. Display screen 5 is used to display the usage and weight of the rust inhibitor and the battery usage. In this embodiment, color change is used to indicate the degree of use of VCI vapor phase rust inhibitor.

[0024] The specific usage process of this utility model is as follows: A certain amount of VCI vapor phase rust inhibitor is placed on the weight sensor 3 of the push-pull component 2, and the push-pull component 2 is pushed into the box 1 along the guide rail groove 102. The hanging ring 203 at one end of the bidirectional memory alloy 202 is hung on the hook 103 at the bottom of the box 1. Insert the battery into the battery compartment 6 and turn on the power switch 7. Use the buttons on the control panel 4 to set the weight of the rust inhibitor when it is close to failure. Generally, when the consumption of VCI vapor phase rust inhibitor reaches 10% to 20% of its own weight, the rust prevention function of VCI vapor phase rust inhibitor will be significantly reduced. The specific setting should be based on the value provided by the VCI vapor phase rust inhibitor manufacturer. When the ambient temperature is low and rapid evaporation of the VCI vapor phase rust inhibitor is required, the bidirectional shape memory alloy 202 is in a stretched state. At this time, the strip-shaped holes 101 and the strip-shaped micro-film holes 201 do not overlap, and the VCI vapor phase rust inhibitor evaporates normally. When the ambient temperature rises, the bidirectional shape memory alloy 202 contracts, pulling the push-pull component 2 along the guide rail groove 102. At this time, the strip-shaped holes 101 and the strip-shaped micro-film holes 201 overlap, thereby slowing down the evaporation of the VCI vapor phase rust inhibitor. When the ambient temperature drops, the bidirectional shape memory alloy 202 returns to a stretched state, pushing the push-pull component 2 along the guide rail groove 102. At this time, the strip-shaped holes 101 and the strip-shaped micro-film holes 201 do not overlap, and the VCI vapor phase rust inhibitor evaporates normally. Display screen 5 displays the battery power and the weight change data of VCI vapor phase rust inhibitor, and simultaneously stores the battery power and the weight change data of VCI vapor phase rust inhibitor in flash memory. When the real-time weight of the rust inhibitor reaches the set failure threshold, the display screen 5 changes to a warning color to indicate the rust inhibitor in the push-pull component 2. When the battery is depleted, the display screen 5 turns off and stores the data in the flash memory. After the staff opens the battery compartment 6 to replace the battery, the display screen 5 can still display the battery level and the weight change data of the VCI vapor phase rust inhibitor.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
