Description

Technical Field

[0001] This utility model relates to the field of concrete steel reinforcement corrosion resistance testing technology, specifically to a concrete steel reinforcement corrosion inhibitor salt immersion test device. Background Technology

[0002] In the research and testing of steel reinforcement corrosion inhibitors, a simulated salt water immersion and drying cycle environment is usually used to evaluate the corrosion resistance of concrete specimens.

[0003] To address the problem that the test method specified in industry standard JGJ / T 192-2009 involves immersion-drying separation and circulation, which is complex and labor-intensive, relevant patents have emerged. For example, Chinese utility model patent with publication number CN215812304U, entitled "A Concrete Salt Water Immersion-Drying Test Machine for Corrosion and Rust Inhibition," includes an immersion-drying chamber, a heater, and a liquid delivery assembly. The heater is fixedly and sealed at the bottom of the immersion-drying chamber; the liquid delivery assembly is connected to the immersion-drying chamber and is used to deliver salt water into the immersion-drying chamber and discharge salt water from the immersion-drying chamber. In the aforementioned concrete salt water immersion and drying test machine for corrosion and rust prevention, the immersion and drying processes of reinforced concrete specimens are both carried out in the immersion and drying chamber. Compared with the previous tests that required repeatedly placing the specimens alternately into the drying chamber and immersion container, this eliminates the need for multiple manual placement and removal of the reinforced concrete from the drying chamber or immersion container, greatly saving test time, reducing the labor intensity of test personnel, and improving test efficiency. At the same time, by avoiding the need for multiple manual placement and removal of the reinforced concrete from the drying chamber or immersion container, the manual intervention in the test process is reduced, improving the accuracy of the test results.

[0004] However, while using a pump to transfer sodium chloride solution can reduce the workload of test personnel to some extent, the injection and drainage of sodium chloride solution also take time, which will prolong the test cycle and reduce the test efficiency. Utility Model Content

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problem of low testing efficiency caused by the extended testing cycle due to the time required for injecting and discharging sodium chloride solution into and out of the heating chamber using a pump, this invention provides a salt immersion testing device for rust inhibitors in concrete reinforcement. This device features interconnected and sequentially arranged immersion chambers 111, draining chambers 112, and drying chambers 113. A drive assembly 400 moves a shelf 300 freely within these chambers, allowing the test material to undergo salt immersion, draining, and drying sequentially. This simulates a salt water immersion-drying cycle to evaluate the corrosion resistance of concrete specimens, reducing manual labor intensity and offering a fast and efficient operation.

[0021] Please see Figures 1 to 3 , Figure 2 This is a schematic diagram of the structure of a salt immersion test device for a concrete rebar rust inhibitor according to an embodiment of the present invention. The salt immersion test device for a concrete rebar rust inhibitor includes: a shell 100, a heating element 200, a shelf 300, and at least one driving component 400. The shell 100 is hollow inside and forms a transfer channel 110. The transfer channel 110 includes a soaking chamber 111, a draining chamber 112, and a drying chamber 113 arranged sequentially and interconnected. The soaking chamber 111 is located below the draining chamber 112 and the drying chamber 113 and is filled with sodium chloride solution. The heating element 200 is built into the drying chamber 113. The shelf 300 is built into the soaking chamber 111 and is configured to place materials. The driving component 400 is connected to the shell 100 and the shelf 300 and is used to drive the shelf 300 and the materials to move in the soaking chamber 111, the draining chamber 112, and the drying chamber 113.

[0022] Compared to existing technologies, this device, by setting up an interconnected and sequentially arranged soaking chamber 111, draining chamber 112, and drying chamber 113, utilizes a drive assembly 400 to drive the shelf 300 to move freely within the soaking chamber 111, draining chamber 112, and drying chamber 113. This allows the material to be tested to undergo salt soaking, draining, and drying steps in sequence, simulating a brine soaking and drying cycle environment for evaluating the corrosion resistance of concrete specimens. This not only reduces the intensity of manual labor but also ensures a fast and efficient operation. It solves the technical problem in existing technologies where the use of pumps to inject and discharge sodium chloride solution into and out of the heating chamber requires a significant amount of time, leading to a prolonged testing cycle and low testing efficiency.

[0023] Furthermore, in this application, during the research and testing of steel reinforcement corrosion inhibitors, a simulated brine immersion and drying cycle environment is typically used to evaluate the corrosion resistance of concrete specimens. The concrete steel reinforcement corrosion inhibitor material needs to be soaked in sodium chloride solution and dried sequentially. The step of simulating the brine immersion and drying cycle environment is a conventional setting known to those skilled in the art. For reference, please refer to Chinese Utility Model Patent No. CN215812304U, entitled "A Concrete Brine Immersion and Drying Test Machine for Corrosion Prevention and Rust Inhibition," which will not be elaborated here.

[0024] Furthermore, the heating element 200 here is a commercially available and purchased electric heater, which can achieve rapid and precise temperature control. It is a conventional setting known to those skilled in the art and will not be described in detail here.

[0025] In some embodiments, the transfer channel 110 is in the shape of an inverted "L", and the drying chamber 113 is located on one side of the draining chamber 112, while the soaking chamber 111 is located below the draining chamber 112.

[0026] In some embodiments, the soaking chamber 111, the draining chamber 112, and the drying chamber 113 in the transfer channel 110 are arranged sequentially in the vertical direction.

[0027] In this embodiment, the housing 100 includes a box body 120 and a box door 130. The box door 130 is hollow inside and forms a transfer channel 110. An opening connected to the transfer channel 110 is provided on one side of the box body 120. The box door 130 is positioned opposite the opening and is hinged to the box body 120 for opening or blocking the opening.

[0028] The hinge between the door 130 and the body 120 allows for the opening and sealing of the opening, facilitating loading and unloading during use.

[0029] Furthermore, the door 130 and the body 120 are hinged together using a hinge, which will not be described in detail here.

[0030] In some embodiments, a handle 140 is also provided on the door 130 for the convenience of the user.

[0031] In this embodiment, as Figure 2 , Figure 3 As shown, the concrete rebar rust inhibitor salt immersion test device also includes a first partition plate 500 and a second partition plate 600. The first partition plate 500 and the second partition plate 600 are arranged perpendicularly to each other and connected to each other. They are both connected to the inner wall of the shell 100, and the first partition plate 500 and the second partition plate 600 together with the inner wall of the shell 100 form a transfer channel 110.

[0032] The first partition plate 500 and the second partition plate 600, which are arranged perpendicularly to each other, form an inverted "L"-shaped transfer channel 110 inside the shell 100. The draining chamber 112 and the drying chamber 113 are located at the same height, so that the material can be separated from the liquid in the soaking chamber 111 under the drive of the drive component 400.

[0033] Furthermore, both the first partition plate 500 and the second partition plate 600 are composite plate structures, that is, a non-metallic heat insulation layer is embedded in a metal substrate and a corrosion-resistant heat insulation coating is sprayed on the outer surface. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0034] In one embodiment, please refer to Figure 2 The second partition plate 600 is vertically arranged and has a groove along its direction. The concrete steel reinforcement rust inhibitor salt immersion test device also includes a heat insulation plate 700, which is slidably inserted into the groove and can abut against the top inner wall of the shell 100.

[0035] By setting a heat insulation plate 700 that can slide relative to the second partition plate 600, the drying chamber 113 can be sealed during the drying process, reducing heat loss and improving heating efficiency.

[0036] Furthermore, the insulation board 700 here is a composite board structure, that is, a non-metallic insulation layer is embedded in a metallic substrate, and a corrosion-resistant insulation coating is sprayed on the outer surface. This is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0037] In some embodiments, the inside of the slide is provided with a linear drive structure. The fixed end of the linear drive structure is connected to the second partition plate 600, and the telescopic end is connected to the heat insulation plate 700, so as to drive the heat insulation plate 700 to slide relative to the second partition plate 600 and abut against the top inner wall of the housing 100 to achieve a sealing effect. This will not be described in detail here.

[0038] Furthermore, the linear drive structure here consists of commonly available and readily procurable push rod motors, cylinders, and hydraulic cylinders, which are conventional setups known to those skilled in the art and will not be described in detail here.

[0039] In this embodiment, as Figure 2 , Figure 3 As shown, the drive assembly 400 includes a first drive member 410 and a second drive member 420. The first drive member 410 has a first fixed end and a first movable end. The first fixed end of the first drive member 410 is connected to the housing 100, and the first movable end is connected to the shelf 300. It is used to drive the shelf 300 and the material to move up and down in the soaking chamber 111 and the draining chamber 112. The second drive member 420 has a second fixed end and a second movable end. The second fixed end of the second drive member 420 is connected to the housing 100, and the second movable end is connected to the first fixed end of the first drive member 410. It is used to drive the shelf 300 and the material to move horizontally in the soaking chamber 111 and the drying chamber 113.

[0040] Driven by the first driving component 410 and the second driving component 420, the shelf 300 and the material can move up and down and move horizontally, thereby enabling the shelf 300 and the material to move within the soaking chamber 111, the draining chamber 112 and the drying chamber 113.

[0041] Furthermore, the first driving component 410 here is a linear drive structure that is common in the market and readily available, such as a push rod motor, a cylinder, and a hydraulic cylinder. This is a conventional configuration known to those skilled in the art and will not be described in detail here.

[0042] In one embodiment, please refer to Figure 2 The second driving member 420 includes at least one guide rail 421 and a sliding member 422. The guide rail 421 is arranged along the extending direction of the draining chamber 112 and the drying chamber 113. The sliding member 422 is connected to the first fixed end of the first driving member 410 and is slidably connected to the guide rail 421.

[0043] The translation of the sliding component 422 and the guide rail 421 enables the free movement of the shelf 300 and the material within the draining chamber 112 and the drying chamber 113.

[0044] Furthermore, the slider 422 here is a common and readily available slide structure on the market, which can slide along the direction of the guide rail 421.

[0045] Furthermore, in some embodiments, such as Figure 3 As shown, there are two drive components 400, which are spaced apart from each other and are connected to the housing 100 and the shelf 300 to improve the stability of materials during the transfer process.

[0046] Furthermore, the two sliders 422 here can move synchronously.

[0047] In this embodiment, as Figure 2 , Figure 3 As shown, the shelf 300 has a hollow structure and at least two storage positions.

[0048] By designing a perforated structure, the contact area between the sodium chloride solution and the material can be increased, thereby improving the accuracy of the test.

[0049] Furthermore, by setting at least two placement positions, it is possible to meet the situation of testing multiple materials simultaneously, thereby increasing the efficiency of the test.

[0050] In some embodiments, the shelf 300 is a basket structure that is common and readily available in the market.

[0051] In one embodiment, please refer to Figures 2 to 4 The concrete steel reinforcement corrosion inhibitor salt immersion test device also includes at least one blower 810, which is built into the draining chamber 112 and set on the material movement path.

[0052] By installing a blower 810 in the draining chamber 112, the separation of sodium chloride solution from the material can be accelerated, and the amount of sodium chloride solution dripping into the drying chamber 113 can be reduced.

[0053] Furthermore, the blower 810 here is a common and readily available piece of equipment on the market, and is a conventional setup known to those skilled in the art, so it will not be described in detail here.

[0054] Furthermore, in some embodiments, such as Figures 2 to 4 As shown, there are two blowers 810, which are spaced apart and both connected to the inner wall of the draining chamber 112.

[0055] In one embodiment, please refer to Figures 2 to 4 The concrete steel reinforcement corrosion inhibitor salt immersion test device also includes at least one temperature sensor 820, which is connected to the inner wall of the drying chamber 113.

[0056] A temperature sensor 820 is also installed inside the drying chamber 113 to monitor the ambient temperature inside the drying chamber 113.

[0057] Furthermore, the temperature sensor 820 here is a common and readily available device on the market, and is a conventional setting known to those skilled in the art, so it will not be described in detail here.

[0058] In one embodiment, please refer to Figures 2 to 4The concrete steel reinforcement corrosion inhibitor salt immersion test device also includes at least one liquid level sensor 830, which is connected to the inner wall of the immersion chamber 111.

[0059] By installing a liquid level sensor 830 in the soaking chamber 111, the liquid level of the sodium chloride solution in the soaking chamber 111 can be detected, which facilitates the replenishment of the soaking chamber 111 and ensures the continuity of the experiment.

[0060] Furthermore, the liquid level sensor 830 here is a common and readily available device on the market, such as a liquid level gauge, which is a conventional setup known to those skilled in the art and will not be described in detail here.

[0061] Furthermore, in some embodiments, the first partition plate 500 and the second partition plate 600 also form a receiving cavity 114 by surrounding the inner wall of the housing 100, such as... Figure 4 As shown, the device also includes a control component 900, which is built into the receiving cavity 114 and is electrically connected to the heating element 200, the first driving element 410, the sliding element 422, the blower 810, the temperature sensor 820 and the liquid level sensor 830 to realize automation and intelligence.

[0062] Furthermore, the control component 900 here is a commonly available and purchased device with a PLC controller, driver and memory, which can accurately control the drying temperature, drying time, cooling time, soaking time and number of soaking and drying cycles in the test process according to standard requirements, which will not be described in detail here.

[0063] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below: The interior of the housing 100 forms an inverted "L"-shaped transfer channel 110. The transfer channel 110 includes a soaking chamber 111, a draining chamber 112, and a drying chamber 113 arranged sequentially and interconnected. The soaking chamber 111 is located below the draining chamber 112 and the drying chamber 113 and is filled with a sodium chloride solution. The heating element 200 is built into the drying chamber 113 for drying materials. The shelf 300 is built into the soaking chamber 111 for placing materials. The drive assembly 400 is connected to the housing 100 and the shelf 300 and is movably built into the rotation channel for driving the shelf 300 and materials to move within the soaking chamber 111, the draining chamber 112, and the drying chamber 113. Compared to existing technologies, by setting up an interconnected soaking chamber 111, a draining chamber 112, and a drying chamber 113 that are arranged in an inverted "L" shape, the drive assembly 400 drives the shelf 300 to move freely within the soaking chamber 111, the draining chamber 112, and the drying chamber 113.

[0064] In the specific workflow of this utility model, when using the equipment, firstly, by setting the control component 900, the drying temperature, drying time, cooling time, soaking time, and number of soaking cycles are preset according to the standard test process; then, the chamber door 130 is manually opened, and the first drive component 410 adjusts the rack 300 to the draining chamber 112. Then, the test material is placed into the rack 300, the chamber door 130 is closed, and the device is started. The first drive component 410 moves the rack 300 to the soaking chamber 111. When the preset soaking time is reached, the first drive component 410 lifts the rack 300 and the test material simultaneously. The blower 810 starts to assist in cooling down. After the preset cooling time is reached, the first drive component 410 moves the rack 300 and the test block material to the drying chamber 113 through the cooperation of the sliding component 422 and the guide rail 421. The heat insulation plate 700 rises to seal the material in the drying chamber 113. The heating component 200 starts to heat to the drying temperature, and the temperature sensor 820 monitors and provides feedback on the drying temperature. After the preset drying time is reached, the heat insulation plate 700 is lowered, and the rack 300 and the test block material are moved horizontally to the draining chamber 112. The above steps are repeated until the cycle ends. The fully automatic salt water immersion drying test machine is then turned off, and the test block is taken out for testing.

[0065] This device allows the material to be tested to undergo salt immersion, draining and drying in sequence, simulating the salt water immersion and drying cycle environment to evaluate the corrosion resistance of concrete specimens. It not only reduces the intensity of manual labor, but also has a fast and efficient operation process.

[0066] This application, through the aforementioned structure, solves the technical problem in the prior art where the use of a pump to inject and discharge sodium chloride solution into the heating chamber requires a significant amount of time, resulting in prolonged experimental cycles and consequently low experimental efficiency. The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
