DETAILED DESCRIPTION

[0018] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0019] The present application provides a long-term test block maintenance device, including: a vortex tube 100, the vortex tube 100 includes a hot air outlet 110 and a cold air outlet 120; a gas supply mechanism 200, which is used to supply compressed gas to the vortex tube 100. After the compressed gas enters the vortex tube 100, part of the compressed gas is heated to form hot gas, which is discharged through the hot gas outlet 110, and another part of the compressed gas is cooled to form cold gas, which is discharged through the cold air outlet 120; a first mixing chamber 310, which is connected to the hot gas outlet 110; a second mixing chamber 320, which is connected to the cold air outlet 120; a liquid supply mechanism 330, which is used to supply the first mixing chamber with liquid. The humidifying liquid is supplied to the first mixing chamber 310 and the second mixing chamber 320. After the humidifying liquid enters the first mixing chamber 310, it can be heated up under the influence of hot air to form a hot liquid. After the humidifying liquid enters the second mixing chamber 320, it can be cooled down under the influence of cold air to form a cold liquid. The curing chamber 400 is used to provide space for curing the test block. The curing chamber 400 is connected to the first mixing chamber 310 and the second mixing chamber 320. When the ambient temperature is lower than the preset temperature, the hot liquid is sprayed to the curing chamber 400 through the first mixing chamber 310. When the ambient temperature is higher than the preset temperature, the cold liquid is sprayed to the curing chamber 400 through the second mixing chamber 320.

[0020] Specifically, the vortex tube 100 is a thermal equipment that can separate compressed air into cold and hot air flows. In one embodiment, the air inlet end of the vortex tube 100 is provided with a plurality of air inlet channels, which are arranged at intervals along the circumferential direction, and each air inlet channel is arranged in an inclined form tangent to the circumference; in this way, the compressed air can be injected into the vortex tube 100 along the tangential direction to form a free vortex; in the vortex tube 100, the air flow is separated into two parts with unequal temperatures after the vortex transformation, the air flow temperature in the center is low, and the air flow temperature in the outer circle is high; a counterflow cone is arranged at the center of the hot air outlet 110, and the low-temperature air flow in the center will flow in the opposite direction after contacting the counterflow cone, and then be discharged from the cold air outlet 120, while the high-temperature air flow in the outer circle can flow out of the hot air outlet 110 from the surroundings of the counterflow cone.

[0021] Therefore, by continuously supplying compressed air to the vortex tube 100 , the vortex tube 100 can continuously generate high-temperature airflow and low-temperature airflow.

[0022] Furthermore, a temperature control valve is provided at the hot gas outlet 110 , and by adjusting the valve opening, the ratio and flow rate of the high-temperature airflow and the low-temperature airflow can be controlled, thereby achieving the purpose of adjusting the output temperature of the vortex tube 100 .

[0023] More specifically, a first mixing chamber 310 is provided downstream of the hot air outlet 110, and a second mixing chamber 320 is provided downstream of the cold air outlet 120; the first mixing chamber 310 and the second mixing chamber 320 are respectively connected to the liquid supply mechanism 330, and the liquid supply mechanism 330 can pass the humidifying liquid (depending on the maintenance needs, the humidifying liquid can be ordinary water or a special solution with specific acidity and alkalinity) into the mixing chamber. Under the influence of hot air, the humidifying liquid will become a hot liquid with a higher temperature, and under the influence of cold air, it will become a cold liquid with a lower temperature.

[0024] In one embodiment, in summer, when the ambient temperature is higher than the preset temperature required for maintenance, the maintenance temperature can be balanced by spraying cold liquid.

[0025] In another embodiment, in winter, when the ambient temperature is lower than the preset temperature required for maintenance, the maintenance temperature can be balanced by spraying hot liquid.

[0026] In another embodiment, the humidifying liquid output by the liquid supply mechanism 330 is affected by the ambient temperature, and its own temperature may be lower than or higher than the preset temperature required for maintenance. By entering the first mixing chamber 310 or the second mixing chamber 320, the humidifying liquid can be temperature-adjusted before entering the maintenance chamber 400, so that the humidifying liquid has the preset temperature.

[0027] The humidification liquid is made to have the preset temperature required for curing by hot air or cold air. After the humidification liquid enters the curing chamber 400, it is used for humidification and temperature control. The temperature directly acts on the test block through the liquid, which is beneficial for the test block to maintain an effective curing state.

[0028] The hot air can heat the first mixing chamber 310 and indirectly heat the humidification liquid entering the first mixing chamber 310 , or can enter the first mixing chamber 310 to mix with the humidification liquid and directly transfer heat with the humidification liquid.

[0029] Similarly, the cold air can heat the humidification liquid entering the second mixing chamber 320 by heating the second mixing chamber 320, or can enter the second mixing chamber 320 to mix with the humidification liquid and directly transfer heat with the humidification liquid.

[0030] When hot air or cold air is directly mixed with the humidifying liquid, the airflow can also serve as a power medium to push the humidifying liquid toward the curing chamber 400 .

[0031] Take concrete specimen curing as an example. Under standard curing conditions, the temperature of the concrete specimen needs to be controlled at 20°C ± 2°C and the relative humidity needs to be maintained at 95% or above.

[0032] It can be seen that the preset temperature required for curing the concrete test block is 20℃±2℃. When the ambient temperature is lower than the preset temperature, the liquid supply mechanism 330 transports the humidifying liquid to the first mixing chamber 310. The humidifying liquid heats up under the influence of the hot air to form a hot liquid. The hot liquid flows into the curing chamber 400 to maintain the temperature of the curing chamber 400 at the preset temperature. When the ambient temperature is higher than the preset temperature, the liquid supply mechanism 330 transports the humidifying liquid to the second mixing chamber 320. The humidifying liquid cools down under the influence of the cold air to form a cold liquid. The cold liquid flows into the curing chamber 400 to maintain the temperature of the curing chamber 400 at the preset temperature. The test block curing equipment provided in the present application generates hot air and cold air through a vortex tube 100. No chemical substances are required and no external energy is input during the temperature control process. It has excellent environmental protection, energy saving and safety, can reduce the impact on the environment, and reduce the cost of use. The humidifying liquid is further temperature-controlled by hot air and cold air, so that the warm liquid is directly applied to the curing chamber 400 and to the test block. Different from the traditional temperature control and humidification operations, the direct action of the warm liquid can more effectively maintain the curing environment and ensure the curing effect, and there is no need to worry about the flow of the humidifying liquid destroying the curing temperature. In addition, the vortex tube 100 can generate hot air and cold air at the same time. During the temperature control process, different mixing chambers can be selected to immediately change the temperature of the humidifying liquid, which has excellent applicability. ‌‌‌ In one embodiment, the air supply mechanism 200 includes an air compressor 210 , and the air compressor 210 is used to compress air.

[0033] Among them, the air compressor 210 can adopt a reciprocating configuration to compress the air through the reciprocating motion of the piston in the cylinder body; it can also adopt a rotary configuration to compress the air through a rotary feeding method such as a screw or a rotor; it can also adopt a centrifugal configuration to accelerate the air through a high-speed rotating impeller, further increase the pressure through a diffuser and a volute, and finally discharge the compressed air.

[0034] Compared with ordinary airflow, compressed air has initial kinetic energy after being compressed; the working principle of the vortex tube 100 is based on the energy conversion of compressed air; the compressed air containing energy is easily converted into cold and hot airflow after entering the vortex tube 100.

[0035] Optionally, the air supply mechanism 200 further includes a nitrogen generator 220 , which is disposed downstream of the air compressor 210 and is used to extract nitrogen from the air; the air supply mechanism 200 is used to supply compressed nitrogen to the vortex tube 100 .

[0036] The nitrogen generator 220 can adopt membrane separation technology, which utilizes the difference in permeation speed of different gas molecules in a specific membrane material to allow nitrogen molecules to quickly pass through the membrane material, while oxygen and other impurity molecules are blocked or slowed down, thereby achieving nitrogen purification and separation; it can also adopt adsorbent technology, which utilizes the adsorption capacity of specific materials (such as molecular sieves, activated carbon, etc.) for impurities such as oxygen in the air, so that oxygen and other impurity molecules are adsorbed on the surface of the adsorbent, while nitrogen is collected through the adsorbent bed.

[0037] For details, please refer to Figure 4 and Figure 5 In the illustrated embodiment, the air compressor 210 compresses the air, and the compressed air enters the nitrogen generator 220 , and the nitrogen generator 220 extracts the nitrogen therein, and finally the compressed nitrogen flows into the vortex tube 100 and serves as the gas source of the vortex tube 100 .

[0038] Different from ordinary compressed air, compressed nitrogen has better cooling and heating performance. This is because the cooling and heating effect of the vortex tube 100 is closely related to the molar mass of the working fluid. The larger the molar mass, the better the cooling and heating performance. The molar mass of nitrogen is greater than that of air. Therefore, using nitrogen in the vortex tube 100 can achieve better cooling and heating effects. In addition, as an inert gas, nitrogen is more chemically stable than air when used in the vortex tube 100, and is not easy to react with other substances, which is conducive to the stable operation of the vortex tube 100.

[0039] Optionally, the first mixing chamber 310 is provided with: a first circulation pipe 311, the first circulation pipe 311 is connected to the curing chamber 400, and hot liquid can enter the curing chamber 400 through the first circulation pipe 311; a first valve 312 is provided on the first circulation pipe 311, and when cold liquid is sprayed from the second mixing chamber 320 to the curing chamber 400, the first valve 312 is closed; a first pressure relief pipe 313, when cold liquid is sprayed from the second mixing chamber 320 to the curing chamber 400, the first pressure relief pipe 313 is opened, and hot gas can be discharged through the first pressure relief pipe 313.

[0040] Optionally, the second mixing chamber 320 is provided with: a second circulation pipe 321, the second circulation pipe 321 is connected to the curing chamber 400, and cold liquid can enter the curing chamber 400 through the second circulation pipe 321; a second valve 322 is provided on the second circulation pipe 321, when hot liquid is sprayed from the first mixing chamber 310 to the curing chamber 400, the second valve 322 is closed; a second pressure relief pipe 323, when hot liquid is sprayed from the first mixing chamber 310 to the curing chamber 400, the second pressure relief pipe 323 is opened, and cold air can be discharged through the second pressure relief pipe 323.

[0041] For details, please refer to Figure 1In the illustrated embodiment, the first mixing chamber 310 is connected to the hot air outlet 110, the liquid supply mechanism 330 and the curing chamber 400. There is no valve between the first mixing chamber 310 and the vortex tube 100, and hot air can flow into the first mixing chamber 310 continuously; in this way, even when hot liquid is not needed to humidify the curing chamber 400, the hot air can continue to heat the first mixing chamber 310 to meet the heating needs. A first valve 312 is provided on the first flow pipe 311 between the first mixing chamber 310 and the curing chamber 400; the first valve 312 can be a manual valve or an automatic valve; the first valve 312 is closed or opened as needed to control the circulation of hot liquid or hot air. A first pressure relief pipe 313 is also provided on one side of the first mixing chamber 310, and an openable and closable valve is also provided on the first pressure relief pipe 313; when hot liquid is not needed to humidify the curing chamber 400, the valve on the first pressure relief pipe 313 is opened to discharge hot air; when hot liquid is needed to humidify the curing chamber 400, the valve on the first pressure relief pipe 313 is closed to facilitate the action of hot air on the inside.

[0042] Continue to refer to Figure 1 , the second mixing chamber 320 is connected to the cold air outlet 120, the liquid supply mechanism 330 and the curing chamber 400. There is no valve between the second mixing chamber 320 and the vortex tube 100, and the cold air can flow into the second mixing chamber 320 continuously; in this way, even when the cold liquid is not needed to humidify the curing chamber 400, the cold air can continue to act on the second mixing chamber 320 to meet the cooling needs. A second valve 322 is provided on the second flow pipe 321 between the second mixing chamber 320 and the curing chamber 400; the second valve 322 can be a manual valve or an automatic valve; the second valve 322 is closed or opened as needed to control the circulation of the cold liquid or cold air. A second pressure relief pipe 323 is also provided on one side of the second mixing chamber 320, and an openable and closable valve is also provided on the second pressure relief pipe 323; when cold liquid is not needed to humidify the curing chamber 400, the valve on the second pressure relief pipe 323 is opened to discharge cold air; when cold liquid is needed to humidify the curing chamber 400, the valve on the second pressure relief pipe 323 is closed to facilitate the effect of cold air on the inside.

[0043] Continue to refer to Figure 1 A valve is provided between the first mixing chamber 310 and the liquid supply mechanism 330 , and a valve is also provided between the second mixing chamber 320 and the liquid supply mechanism 330 .

[0044] In one embodiment, when the ambient temperature is lower than the preset temperature, the valve between the first mixing chamber 310 and the liquid supply mechanism 330 is opened, and the valve between the second mixing chamber 320 and the liquid supply mechanism 330 is closed, and the humidification liquid only enters the first mixing chamber 310. In the first mixing chamber 310, the valve on the first pressure relief pipe 313 is closed to facilitate the hot air to heat the humidification liquid and obtain hot liquid; the first valve 312 is opened to facilitate the hot liquid to enter the curing chamber 400. At the same time, in the second mixing chamber 320, the valve on the second pressure relief pipe 323 is opened, and cold air can be discharged through the second pressure relief pipe 323; the second valve 322 is closed to prevent cold air from entering the curing chamber 400 and destroying the hot liquid environment.

[0045] In another embodiment, when the ambient temperature is higher than the preset temperature, the valve between the second mixing chamber 320 and the liquid supply mechanism 330 is opened, and the valve between the first mixing chamber 310 and the liquid supply mechanism 330 is closed, and the humidification liquid only enters the second mixing chamber 320. In the second mixing chamber 320, the valve on the second pressure relief pipe 323 is closed, so that the cold air can cool the humidification liquid and obtain cold liquid; the second valve 322 is opened, so that the cold liquid can enter the curing chamber 400. At the same time, in the first mixing chamber 310, the valve on the first pressure relief pipe 313 is opened, and the hot air can be discharged through the first pressure relief pipe 313; the first valve 312 is closed to prevent the hot air from entering the curing chamber 400 and destroying the cold liquid environment.

[0046] In one embodiment, a nozzle is provided in the curing chamber 400 , and the nozzle is connected to the first mixing chamber 310 and the second mixing chamber 320 , and hot liquid or cold liquid can be sprayed into the curing chamber 400 evenly and comprehensively through the nozzle.

[0047] In another embodiment, reference may be made to Figure 2 The liquid supply mechanism 330 includes: a liquid storage chamber 331 for storing humidification liquid; an atomizer 332, connecting the liquid storage chamber 331, the first mixing chamber 310 and the second mixing chamber 320; during the maintenance process, the humidification liquid is made into water mist by the atomizer 332 and can selectively enter the first mixing chamber 310 or the second mixing chamber 320 for temperature change.

[0048] The liquid storage chamber 331 can be any cavity, tank, barrel or other container that is convenient for storing humidified liquid. The atomizer 332 can be an ultrasonic humidifier, which uses ultrasonic high-frequency oscillation to atomize the liquid into ultrafine particles of 1 to 5 microns and negative oxygen ions; or a water mist nozzle can be used to decompose the liquid into water droplets smaller than 1 mm through centrifugal atomization or impact atomization, forming a water mist that expands around the axis of the nozzle.

[0049] The humidified liquid is atomized before entering the mixing chamber and enters the mixing chamber in the form of water mist, which is more conducive to changing the temperature of the liquid by hot air or cold air; at the same time, the water mist has small particles and small mass, and the hot air or cold air can also effectively push the temperature-changed water mist to move toward the curing chamber 400.

[0050] Optionally, the liquid supply mechanism 330 also includes a reflux chamber 333, which connects the curing chamber 400 and the liquid storage chamber 331; during the curing process, after the water mist is sprayed into the curing chamber 400, the converged water flow can flow out of the curing chamber 400, enter the reflux chamber 333, and then return to the liquid storage chamber 331 through the reflux chamber 333.

[0051] It is easy to understand that water is easily accumulated in the curing chamber 400 during the continuous water spraying process, but curing does not require the test block to be immersed in liquid, so the accumulated water needs to be drained in time.

[0052] To facilitate drainage, a drain port 401 may be provided at the bottom of the curing chamber 400 ; when water accumulates, the accumulated water may be discharged through the drain port 401 .

[0053] The reflux chamber 333 is connected to the drain port 401 of the curing chamber 400, and the accumulated water can be discharged into the reflux chamber 333. The reflux chamber 333 is connected to the liquid storage chamber 331, which is also conducive to the recycling of the humidification liquid and further reduces the working cost.

[0054] Optionally, the reflux chamber 333 can temporarily store the liquid so that the liquid can return to the ambient temperature.

[0055] As can be seen from the above, the curing equipment provided by the present application can spray hot liquid or cold liquid into the curing chamber 400, and optimize the curing environment by means of warm humidified liquid. Therefore, the discharged accumulated water often also has temperature. By temporarily storing the liquid in the reflux chamber 333 and restoring the liquid to the ambient temperature, it is possible to prevent the liquid from directly refluxing and affecting the existing liquid in the liquid storage chamber 331.

[0056] At the same time, the reflux chamber 333 has a certain volume and can store humidification liquid. The reflux chamber 333 can also serve as a reserve liquid source. When necessary, the reflux chamber 333 supplies liquid to the liquid storage chamber 331 to ensure that the maintenance work continues.

[0057] Optionally, a filter is provided in the reflux chamber 333, and the filter can filter out impurities in the liquid.

[0058] It is easy to understand that after the humidification liquid acts in the curing chamber 400, it may carry impurities such as dust and test block debris due to contact with the test block. When the humidification liquid is recycled, it is necessary to filter out the impurities first to prevent the impurities from clogging the pipeline during circulation, damaging the equipment, and even interfering with the curing of the test block.

[0059] The filter may be any filter structure such as a filter screen or a filter element that can filter out small particles of impurities.

[0060] Optionally, a drain port 401 is provided at the bottom of the curing chamber 400 , and the gathered water flow can leave the curing chamber 400 through the drain port 401 ; a plurality of drainage grooves 402 are provided on the inner bottom surface of the curing chamber 400 , and the drainage grooves 402 are connected to the drain port 401 .

[0061] For details, please refer to Figure 6 In the illustrated embodiment, a drain port 401 is provided at the rear side of the bottom of the curing chamber 400, and a plurality of drainage grooves 402 are radially distributed with the drain port 401 as the center. In this way, water flowing from various parts and corners in the curing chamber 400 can flow into the drainage grooves 402 and flow along the drainage grooves 402 to the drain port 401.

[0062] A drainage groove 402 is opened at the bottom of the curing chamber 400. The groove width of the drainage groove 402 is smaller than the size of the test block. When the test blocks are stacked in the curing chamber 400, the test blocks will be placed on the drainage groove 402. The design of the drainage groove 402 is convenient for collecting water flow, guiding water flow to the drain port 401, and preventing the bottom of the test block from being immersed in water.

[0063] Furthermore, the closer to the drain outlet 401 , the deeper the drainage groove 402 is, so that the water can actively flow toward the drain outlet 401 .

[0064] By gradually changing the depth of the drainage groove 402, the water flow channel formed by the drainage groove 402 is similar to a slide and has a certain slope; the closer to the drainage port 401, the lower the slope of the drainage groove 402. In this way, after the water enters the drainage groove 402, it will actively move along the drainage groove 402 to the drainage port 401 under the influence of its own weight. The inclined drainage groove 402 is conducive to rapid drainage, thereby preventing a large amount of water from accumulating in the curing room 400.

[0065] Optionally, the long-term test block curing equipment provided in the present application also includes a temperature control room 340, which connects the first mixing chamber 310, the second mixing chamber 320 and the curing chamber 400, and the hot liquid or the cold liquid enters the curing chamber 400 after passing through the temperature control room 340; when the hot liquid is sprayed from the first mixing chamber 310 to the curing chamber 400, if the temperature of the hot liquid is greater than the preset temperature, the cold air enters the temperature control room 340 through the second mixing chamber 320, and the cold air acts on the hot liquid to achieve cooling; when the cold liquid is sprayed from the second mixing chamber 320 to the curing chamber 400, if the temperature of the cold liquid is lower than the preset temperature, the hot air enters the temperature control room 340 through the first mixing chamber 310, and the hot air acts on the cold liquid to achieve heating.

[0066] For details, please refer to Figure 3In the illustrated embodiment, a temperature-control chamber 340 is provided downstream of the first mixing chamber 310 and the second mixing chamber 320 and upstream of the curing chamber 400. A valve is provided between the first mixing chamber 310 and the temperature-control chamber 340, and a valve is also provided between the second mixing chamber 320 and the temperature-control chamber 340. When hot liquid is passed, the valve between the second mixing chamber 320 and the temperature-control chamber 340 is closed, and the hot liquid generated in the first mixing chamber 310 can pass through the temperature-control chamber 340 and enter the curing chamber 400. When cold liquid is passed, the valve between the first mixing chamber 310 and the temperature-control chamber 340 is closed, and the cold liquid generated in the second mixing chamber 320 can pass through the temperature-control chamber 340 and enter the curing chamber 400. If the temperature of the hot liquid is higher than the preset temperature, the valve between the second mixing chamber 320 and the temperature-control chamber 340 is opened to allow cold air or cold liquid to enter the temperature-control chamber 340, thereby cooling the hot liquid. If the temperature of the cold liquid is lower than the preset temperature, the valve between the first mixing chamber 310 and the temperature-regulating chamber 340 is opened to allow the hot gas or hot liquid to enter the temperature-regulating chamber 340, thereby cooling the hot liquid.

[0067] The additional temperature control room 340 can confirm and assist in regulating the temperature of the humidification liquid before the liquid is introduced into the curing room 400, thereby ensuring the uniformity and stability of the temperature of the humidification liquid, and further ensuring that the temperature control and humidity control of the curing room 400 remain in a balanced state and can be carried out continuously.

[0068] Optionally, a drain port 401 is provided on the curing chamber 400, and the gathered water flow can leave the curing chamber 400 through the drain port 401; the long-term test block curing equipment also includes a reflux pipe, which connects the drain port 401 and the liquid supply mechanism 330, passes through the temperature-controlling chamber 340, and can transfer heat with the temperature-controlling chamber 340.

[0069] It is easy to understand that the liquid sprayed into the curing chamber 400 is a hot liquid or a cold liquid with temperature, so the water flow gathered in the curing chamber 400 often has temperature. The warm water flows into the return pipe through the drain port 401, and can flow back to the liquid supply mechanism 330 along the return pipe for recycling. During the process of water flow reflux, the water flow will pass through the temperature-control chamber 340 along the return pipe, and the water flow can indirectly transfer its own waste heat or waste cold to the temperature-control chamber 340 by heat transfer, so that the temperature-control chamber 340 maintains the preset temperature.

[0070] In one embodiment, the return pipe is wound outside the temperature-controlled chamber 340. By spirally winding, the flow path of the water flow can be extended, the heat transfer area between the water flow and the temperature-controlled chamber 340 can be increased, and the water flow can transfer the residual heat or residual cold to the temperature-controlled chamber 340.

[0071] In another embodiment, the return pipe is arranged in a winding manner and reciprocatedly inserted in the temperature-control room 340. When the return pipe is inserted into the temperature-control room 340, the return pipe can directly transfer heat with the hot liquid or cold liquid in the temperature-control room 340, and the waste heat or waste cold can be better utilized. The winding return pipe structure can also extend the flow path of the water flow and increase the heat transfer area between the water flow and the curing room 400.

[0072] Optionally, the long-term test block curing equipment provided in the present application further includes: a first thermometer for monitoring the temperature of the curing chamber 400; a second thermometer for monitoring the temperature of the hot liquid; and a third thermometer for monitoring the temperature of the cold liquid.

[0073] The thermometer may be any device capable of detecting temperature, such as a thermocouple or an infrared temperature measuring instrument.

[0074] By setting the first thermometer in the curing room 400 , the curing temperature can be checked at any time to ensure that the test block is in a preset temperature environment. Of course, the curing equipment also includes a hygrometer for monitoring the humidity of the curing room 400 .

[0075] The second thermometer can be arranged at the air inlet of the first mixing chamber 310 to confirm the temperature of the hot gas, or can be arranged in the first mixing chamber 310 to confirm the temperature of the first mixing chamber 310, or can be arranged at the liquid outlet of the first mixing chamber 310 to confirm the specific temperature of the hot liquid. By monitoring the temperature of the hot liquid with the second thermometer, it can be confirmed whether the hot liquid meets the preset temperature requirement; when the temperature of the hot liquid is too high or too low, the temperature of the hot gas can be adjusted by the temperature control valve arranged at the hot gas outlet 110, thereby adjusting the temperature of the hot liquid, or by introducing cold air or cold liquid into the temperature control chamber 340 for adjustment.

[0076] The third thermometer can be arranged at the air inlet of the second mixing chamber 320 to confirm the temperature of the cold air, or can be arranged in the second mixing chamber 320 to confirm the temperature of the second mixing chamber 320, or can be arranged at the liquid outlet of the second mixing chamber 320 to confirm the specific temperature of the cold liquid. By monitoring the temperature of the cold liquid with the third thermometer, it can be confirmed whether the cold liquid meets the requirement of the preset temperature; when the temperature of the cold liquid is too high or too low, the temperature of the cold air can be adjusted by the temperature control valve arranged at the hot air outlet 110, thereby adjusting the temperature of the cold liquid, or hot air or hot liquid can be introduced into the temperature control chamber 340 for adjustment.

[0077] Optionally, the long-term test block curing equipment provided in the present application further includes a fourth thermometer, which is used to monitor the temperature of the conditioning chamber 340 .

[0078] The configuration of the fourth thermometer is similar to that of the first, second and third thermometers, and will not be described in detail.

[0079] By monitoring the temperature of the conditioning chamber 340 through the fourth thermometer, it is possible to confirm whether the conditioning chamber 340 and the humidifying liquid therein are at a preset temperature. If the temperature of the conditioning chamber 340 does not meet the preset temperature, the temperature of the hot gas and the cold gas can be adjusted by the temperature control valve provided at the hot gas outlet 110, and then the temperature of the hot liquid or the cold liquid can be adjusted; the temperature of the hot liquid in the conditioning chamber 340 can also be adjusted by introducing cold gas or cold liquid, or the temperature of the cold liquid in the conditioning chamber 340 can be adjusted by introducing hot gas or hot liquid.

[0080] Optionally, the curing chamber 400 includes: a bracket 410, the bracket 410 constructs multiple rows and columns of cavities; multiple drawer-type brackets 420, a drawer-type bracket 420 is slidably arranged in any cavity, and the drawer-type bracket 420 can store multiple test blocks.

[0081] For details, please refer to Figure 7 In the illustrated embodiment, the curing room 400 is in the form of a drawer-type shelf. The bracket 410 is made of stainless steel, and the drawer-type bracket 420 is also made of stainless steel; after the drawer-type bracket 420 is pushed into the cavity, it can be sealed and connected with the bracket 410, thereby forming a closed curing environment in the curing room 400.

[0082] Since each drawer-type bracket 420 can independently store a batch of test blocks, the curing room 400 can conveniently store multiple batches of test blocks. After a batch of test blocks is cured, the corresponding drawer-type bracket 420 can be opened separately without interfering with the curing of test blocks in other drawer-type brackets 420. The curing room 400 in the form of a drawer-type shelf can make full use of the workshop space and realize the regional curing of test blocks; the drawer-type bracket 420 can be opened and closed by pushing and pulling, which is convenient and practical.

[0083] Optionally, the long-term test block curing equipment further includes: a three-dimensional storage shelf 510 for storing test blocks in different areas; and a transport robot 520 capable of traveling back and forth between the three-dimensional storage shelf 510 and the curing room 400 for transporting test blocks.

[0084] For details, please refer to Figure 7 In the illustrated embodiment, the three-dimensional storage shelf 510 is constructed of pipes. The three-dimensional storage shelf 510 includes multiple rows and columns of cargo rooms, each of which can store a batch of test blocks. A cargo fork is also provided in the cargo room. When the cargo fork is extended, it can receive materials or deliver materials. When the cargo fork is retracted, it can store materials in the cargo room. The cargo fork can cooperate with the transport robot 520 to realize loading and unloading of the three-dimensional storage shelf 510.

[0085] Continue to refer to Figure 7The transport robot 520 is in the form of a manipulator and an AGV trolley. The manipulator can grab the test blocks and stack them on the AGV trolley. The AGV trolley can transport the test blocks to be cured to the location of the curing room 400, and then the manipulator opens the drawer-type bracket 420 and places the test blocks into the drawer-type bracket 420. After a batch of test blocks is delivered, the manipulator closes the drawer-type bracket 420, and the manipulator and the AGV trolley can return to the three-dimensional storage shelf 510 to receive a new batch of test blocks, or the manipulator and the AGV trolley can cooperate to take out a batch of test blocks that have completed curing in the curing room 400, and then store this batch of test blocks in the three-dimensional storage shelf 510, so as to facilitate the control system to count the test blocks.

[0086] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
