AI Technical Summary
In a cement curing box, steam may condense into water droplets and drip onto the sample to be tested, resulting in small pits that may appear when the sample is not strong enough, which will make the sample unusable.
A cement standard maintenance box was designed, using a wiper mechanism and exhaust mechanism to solve the problem. The wiper mechanism includes a wiper plate, a servo motor-driven drive threaded rod that moves back and forth through these components to scrape away condensate droplets on the top of the curing box and collect it into the water tank. The exhaust mechanism uses a suction fan and sealing assembly to discharge the humid air in the curing box to prevent water droplets from falling.
It effectively reduces the possibility that water vapor condenses into water droplets on the top of the box and drips, prevents small pits from appearing on the cement test block to be tested, thereby ensuring the usability of the test block. At the same time, the exhaust mechanism reduces the risk of humid air entering the laboratory and protects the experimental environment.

Technical Field
[0001] This application relates to the field of cement curing, and particularly to a cement standard curing box. Background Art
[0002] The cement curing box is designed and manufactured according to the requirements of the state for specimens such as cement concrete and cement products. It is applicable to various cement product factories, construction units, highway and bridge projects, and relevant scientific research and quality inspection departments for curing the strength, setting property, and setting time of cement, concrete, and cement product specimens.
[0003] An existing Chinese patent (Publication No.: CN220094960U) mentions a cement curing water tank with uniform temperature rise, including a cement curing box body and a uniform temperature rise mechanism. In the present utility model, through the setting of the uniform temperature rise mechanism, during the process of uniformly raising the temperature inside the cement curing box body, first, water is poured into the water tank through the water inlet, and then the screw is screwed clockwise into the threaded hole to fix the fixing plate. At this time, the water pump is started, and the water pump sucks the water inside the water tank into the inside of the cement curing box body through the water inlet pipe. Then, the operator needs to observe the first scale so that the water source inside the cement curing box body can submerge the heating pipe. Then, the water pump is turned off. At this time, the connector is inserted into the connection hole to energize and heat the heating pipe, making the water inside the cement curing box body boil, thereby generating steam, which effectively guarantees the uniform temperature rise inside the cement curing box body.
[0004] In actual use, during the process of cement curing, generally a relatively high humidity is required. When the steam used for curing the cement specimens enters the cement curing box, the steam may condense into water droplets on the top of the box, and then there is a probability of dripping onto the test samples. In the case where the strength of the test samples is insufficient, small pits may be dripped out on the top plate of the test samples, making the test samples unusable. Summary of the Utility Model

[0032] The following further describes this application in detail in conjunction with the attached Figure 1 —4.
[0033] The embodiment of this application discloses a cement standard curing box.
[0034] Referring to Figure 1 , Figure 2 and Figure 3 , a cement standard curing box includes a curing box body 1, a control panel 2 is installed on the curing box body 1, a box door 3 is hinged on one side of the curing box body 1, a heating and humidifying device 4 is installed at the bottom of the curing box body 1, a water tank 5 is installed on one side of the heating and humidifying device 4, a plurality of support plates 8 are slidably connected inside the curing box body 1, a wiper mechanism 6 is arranged inside the curing box body 1, and an exhaust mechanism 7 is arranged on the curing box body 1.
[0035] When it is necessary to use the curing box body 1 for curing cement test blocks, first evenly place the cement test blocks on the support plate 8, then close the box door 3 on the curing box body 1, and then use the control panel 2 to control the heating and humidifying device 4 to work. The heating and humidifying device 4 heats the water in the water tank 5, and then the water vapor enters the curing box body 1 from the bottom of the curing box body 1 to cure the cement test blocks. During the curing process, the water scraping mechanism 6 moves back and forth at the top inside the curing box body 1 to scrape off the water condensed when the water vapor contacts the top inside the curing box body 1, and collects it using the water scraping mechanism 6. After the curing is completed, connect the exhaust mechanism 7 to the outside, and discharge the water vapor inside the curing box body 1 to the outside. Then open the box door 3 to take out the cement test blocks. When using the curing box body 1 to cure the cement test blocks, by using the water scraping mechanism 6 to move back and forth at the top inside the curing box body 1, the condensed water droplets on the top inside the curing box body 1 can be scraped off, thereby reducing the possibility that water vapor may condense into water droplets on the top of the box and then may drip onto the cement test blocks to be measured. In the case where the strength of the cement test blocks to be measured is insufficient, small pits may be dripped out on the top of the cement test blocks to be measured, making the cement test blocks to be measured unusable.
[0036] Referring to Figure 1 、 Figure 2 and Figure 3 , the water scraping mechanism 6 includes a water scraping plate 61 arranged inside the curing box body 1. The water scraping plate 61 abuts against the top inside the curing box body 1. A drainage arc plate 62 is fixed on the water scraping plate 61. One end of the drainage arc plate 62 is provided with a driving component 63, and the other end of the drainage arc plate 62 away from the driving component 63 is provided with a collecting component 64. One end of the drainage arc plate 62 close to the collecting component 64 is inclined downward.
[0037] In addition, the driving component 63 includes a servo motor 631 fixed on the curing box body 1. The output end of the servo motor 631 penetrates the curing box body 1 and is fixed with a driving threaded rod 633. The other end of the driving threaded rod 633 away from the servo motor 631 is rotatably connected to a support block 632. The support block 632 is fixedly connected to the curing box body 1. A threaded block 634 is threadedly connected to the driving threaded rod 633. The threaded block 634 is fixedly connected to one end of the drainage arc plate 62.
[0038] Moreover, the collecting component 64 includes a first collecting pipe 641 fixed inside the curing box body 1. A second collecting pipe 642 is fixed in the middle of the first collecting pipe 641. The other end of the second collecting pipe 642 away from the first collecting pipe 641 is communicated with the water tank 5. The first collecting pipe 641 is inclined downward from both ends to the middle. The drainage arc plate 62 corresponds to the first collecting pipe 641. The first collecting pipe 641 is open in the direction towards the drainage arc plate 62.
[0039] When closing the box door 3 to cure the cement specimens in the curing box body 1, first start the servo motor 631. The servo motor 631 drives the driving threaded rod 633 to rotate back and forth, causing the threaded block 634 to move back and forth on the driving threaded rod 633. The threaded block 634 drives the drainage arc plate 62, and the drainage arc plate 62 drives the wiper plate 61. The wiper plate 61 moves back and forth to scrape off the condensed water droplets on the top inside the curing box body 1. The scraped water droplets fall on the drainage arc plate 62 and converge on it. Then, under the action of the inclination angle of the drainage arc plate 62, the converged water droplets flow towards the first collection pipe 641. Then, under the action of the first collection pipe 641 with higher ends and lower middle, the water droplets flow into the second collection pipe 642. The second collection pipe 642 is connected to the water tank 5, and all the collected water enters the water tank 5 to be reused. By using the wiper plate 61 to move back and forth driven by the servo motor 631, the condensed water droplets on the top inside the curing box body 1 are scraped off, and the drainage arc plate 62, the first collection pipe 641, and the second collection pipe 642 are used to drain the water into the water tank 5, so as to reduce the possibility that the humid air inside the curing box body 1 condenses into water droplets on the top inside the curing box body 1 and drips on the cement specimens to be tested. In the case where the strength of the cement specimens to be tested is insufficient, small pits may be dripped on the top of the cement specimens to be tested, making the cement specimens to be tested unusable.
[0040] Referring to Figure 2 and Figure 3 One end of the drainage arc plate 62 close to the first collection pipe 641 is fixed with a lapping block 643. The lapping block 643 laps on the first collection pipe 641 and is slidably connected to the first collection pipe 641.
[0041] When the drainage arc plate 62 moves back and forth, the drainage arc plate 62 drives the lapping block 643 to move. The lapping block 643 slides back and forth on the first collection pipe 641. The lapping block 643 extends into the first collection pipe 641. The water collected from the drainage arc plate 62 enters the first collection pipe 641 under the drainage of the lapping plate. By using the lapping block 643 to lap the drainage arc plate 62 on the first collection pipe 641, one end of the drainage arc plate 62 far from the threaded block 634 can be supported, and at the same time, the possibility that the water flowing through the drainage arc plate 62 flows outside the first collection pipe 641 can be reduced.
[0042] Referring to Figure 1 , Figure 2 and Figure 4 As shown in FIGS.
[0043] In addition, the sealing assembly 74 includes a movable cover 742 disposed on the support ring 76 . The movable cover 742 is located in the exhaust hole 75 . A sealing cover 741 is fixed on the movable cover 742 . The sealing cover 741 corresponds to the inner wall of the support ring 76 .
[0044] In addition, a moving block 743 is fixed to one side of the moving cover 742 , and the moving block 743 is slidably connected to the maintenance box 1 . A moving bolt 744 is threadedly connected to the moving block 743 , and the moving bolt 744 passes through the moving block 743 and is rotatably connected to the maintenance box 1 .
[0045] When the movable cover 742 is covered on the support ring 76, the sealing cover 741 on the movable cover 742 enters the inner ring of the support ring 76 to seal, the sealing cover 741 is flush with the top of the curing box 1, and an annular space is left between the edge of the movable cover 742 and the inner wall of the exhaust hole 75. After the cement test block in the curing box 1 is cured, the exhaust pipe 72 on the suction fan 73 is first connected to the outside through a pipeline, and then the movable bolt 744 is rotated to allow the movable block 743 to drive the movable cover 742, and the movable cover 742 drives the sealing cover 74 1, the sealing cover 741 moves out from the inner wall of the support ring 76, and then a connecting space appears between the support ring 76 fixed on the inner wall of the exhaust hole 75 and the movable cover 742, and then the suction fan 73 is started, and the suction fan 73 uses the connecting pipe 71 to extract the humid air in the curing box 1, and the humid air in the curing box 1 is discharged to the outside by using the suction fan 73 and the connecting pipe 71, thereby reducing the humid air in the curing box 1 from entering the experimental room when the box door 3 is opened, thereby reducing the possibility of affecting the indoor experimental environment.
[0046] Working principle: When it is necessary to use the curing box 1 for curing cement specimens, first evenly place the cement specimens on the support plate 8, then close the door 3 of the curing box 1, and then use the control panel 2 to control the heating and humidifying device 4 to work. The heating and humidifying device 4 heats the water in the water tank 5, and then the water vapor enters the curing box 1 from the bottom of the curing box 1 to cure the cement specimens. Start the servo motor 631, and the servo motor 631 drives the driving threaded rod 633 to rotate back and forth, so that the threaded block 634 moves back and forth on the driving threaded rod 633, and the threaded block 634 drives the drainage arc plate 62. The drainage arc plate 62 drives the wiper plate 61, and the wiper plate 61 moves back and forth to scrape off the condensed water droplets on the top of the curing box 1. The scraped water droplets fall on the drainage arc plate 62 and converge on the drainage arc plate 62. Then, under the action of the inclination angle of the drainage arc plate 62, the converged water droplets flow towards the first collecting pipe 641. Then, under the action of the high-middle-low of both ends of the first collecting pipe 641, the water droplets flow into the second collecting pipe 642. The second collecting pipe 642 is communicated with the water tank 5, and the collected water all enters the water tank 5 to be reused. After the curing is completed, use a pipeline to connect the exhaust pipe 72 on the suction fan 73 with the outside, and then rotate the moving bolt 744, so that the moving block 743 drives the moving cover 742, the moving cover 742 drives the sealing cover 741, and the sealing cover 741 moves out from the inner wall of the support ring 76. Then, a communicating space appears between the support ring 76 fixed on the inner wall of the exhaust hole 75 and the moving cover 742. Then start the suction fan 73, and the suction fan 73 uses the communicating pipe 71 to suck out the humid air in the curing box 1, and then open the door 3 to take out the cement specimens.
