[0002] In cement product quality testing, cement samples need to be prepared into specimens and cured in a specified temperature and humidity environment until the designated age. The uniformity and stability of the curing temperature affect the accuracy of the test results.

[0003] After the cement test blocks are formed, before demolding, they need to be placed in a curing chamber at a temperature of 20℃±1℃ and a humidity of ≥90%RH for 24 hours. Then, they are demolded and placed in a curing pool at 20℃±1℃ for 3 to 28 days. The heat of hydration of the cement test blocks and the humid air in the curing chamber increase the difficulty of temperature and humidity control.

[0004] Existing cement block curing boxes and curing pools suffer from uneven heat transfer, making it difficult to reach the standard requirement of 20℃±1℃.

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] The purpose of this invention is to provide a cement test block curing box, curing pool and curing system to solve the problems existing in the prior art, and to achieve more precise control of temperature and humidity during the curing process.

[0047] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] Heat transfer occurs in three ways: conduction, radiation, and convection. A temperature difference is a prerequisite for heat transfer; the smaller the temperature difference, the slower the conduction and radiation heat transfer. This is the main reason for the uneven temperature distribution within cement block curing boxes and curing tanks. Convection heat transfer, however, is not affected by the size of the temperature difference. Based on this, the present invention provides a cement block curing box, such as… Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, the system includes a curing box body with an insulation layer on the side walls, and the interior of the curing box body is sealable; multiple water tank groups are fixed to the curing box body from top to bottom, each water tank group has a nozzle 32 at one end, and adjacent water tank groups are connected; a test mold support 34 is movably disposed in the water tank group, and the level of the test mold support 34 in the water tank group is adjustable; a test mold 31 for placing cement test blocks is placed on the test mold support 34; a circulating water tank 25 is fixed to the bottom of the curing box body at one end, and the circulating water tank 25 is connected to multiple nozzles 32 through a pipeline connected to a circulating pump. The nozzles 32 can spray water in the circulating water tank 25 into the corresponding water tank group, and the water flowing in the water tank group does not contact the test mold 31. The water in the bottom water tank group can fall into the circulating water tank 25; the circulating water tank 25 is connected to a temperature control module, which can regulate the temperature of the water in the circulating water tank 25. This invention uses a circulating water pump 44 and nozzles 32 to spray water at a set temperature from the circulating water tank 25 into the water tank assembly. This causes the water to circulate at the bottom area of ​​the mold support 34. The small distance between the water in the water tank assembly and the mold support 34 reduces the conduction heat transfer distance. The top-to-bottom circulation of the water increases the convective heat transfer path, improves the heat transfer rate, and achieves uniform temperature. The airflow generated by the water jets from the nozzles 32, combined with the water circulation and air circulation, ensures that each mold 31 is in a constant-temperature water and air circulation environment, achieving convective heat transfer and ensuring uniform heat conduction among the molds 31.

[0049] To ensure smoother water circulation, in one embodiment, the water tank assembly includes an inclined water tank 33 and a flat water tank 35. The inclined water tank 33 is inclined above the flat water tank 35, and the mold support 34 is mounted on the flat water tank 35. The nozzle 32 is located at the lower end of the inclined water tank 33. One end of the flat water tank 35 is connected to the lower end of the inclined water tank 33. Condensed water droplets on the lower surface of the inclined water tank 33 slide down the inclined surface to the lower end and then fall into the adjacent flat water tank 35 below, without dripping onto the mold 31. The other end of the flat water tank 35 is connected to the water tank below it. The higher end of the inclined water tank 33 of the trough group is connected, so the water falling into the horizontal water tank 35 will flow from one end of the horizontal water tank 35 to the other end, and then fall to the higher end of the inclined water tank 33 of the adjacent water tank group below. The higher end of the inclined water tank 33 of the adjacent water tank group below receives the circulating water falling from above and combines it with the water sprayed from the corresponding nozzle 32 of the inclined water tank 33, and then slides down to the lower end of the inclined water tank 33. The horizontal water tank 35 of the bottom water tank group is connected to the circulating water pool 25, and the water circulates in sequence. Finally, the water flows into the circulating water pool 25, forming a reciprocating circulation of circulating water.

[0050] To facilitate gas flow, in one embodiment, a guide channel 331 is provided on the inclined surface of the inclined water tank 33. The guide channel 331 is located in front of the nozzle, and one end of the guide channel 331 near the nozzle 32 has an inlet directly facing the water outlet direction of the nozzle 32. The guide channel 331 has multiple outlets at the other end away from the nozzle 32. The bottom of the guide channel 331 is connected to the inclined water tank 33. Multiple channel plates are provided inside the inlet of the guide channel 331, dividing the inlet into multiple inlet areas. Each inlet area of ​​the guide channel 331 corresponds to one of the multiple outlets, and the inlet areas and corresponding outlets are connected by a multi-bend airflow channel. Nozzle 3... The sprayed circulating water increases air humidity and drives airflow, forming a wind circulation. The water flow from nozzle 32 drives the airflow in the guide channel. The sprayed water and flowing air enter the guide channel 331 through the inlet. The water flow enters the inclined water tank 33 from the bottom of the guide channel 331. The flowing air changes direction continuously along the bending structure of the airflow channel and flows continuously. During this period, water droplets in the air will adhere to the bending structure of the airflow channel, thereby separating the water droplets contained in the flowing air and finally flowing out from the outlet of the channel plate away from nozzle 32. Together with the airflow outside the guide channel 331, it drives the airflow around the test mold 31, making the temperature distribution inside the box 1 more uniform.

[0051] Multiple ventilation holes 341 are provided on the side wall of the groove of the mold support 34 to facilitate heat exchange between the mold 31 and the circulating water in the flat water tank 35 below. The ventilation holes 341 are provided on the side wall of the groove, but no ventilation holes 341 are provided at the bottom of the groove to prevent residue brought in by the mold 31 from falling into the flat water tank 35 and contaminating the circulating water. The water spray from the nozzle 32 replaces the easily malfunctioning electric fan and humidifier, ensuring reliable operation. In this embodiment, the guide channel 331 collects the water spray from the nozzle 32 and also divides the airflow driven by the water spray into inner and outer parts. The airflow inside the guide channel 331 flows out after separating the water droplets, forming a combined force with the airflow outside the guide channel 331, enhancing the air circulation around the mold 31, and preventing the circulating air from carrying water droplets. The bottom of the mold support 34 is equipped with a height adjustment device 342, which can be a bolt or a screw. The height adjustment device 342 can adjust the level of the mold support 34 to keep the mold 31 level and prevent the mold 31 from tilting and causing the mortar to flow in the early stage of molding, thus damaging the shape of the cement block 7.

[0052] A circulating water pump 44 is connected to the outlet of the circulating water tank 25 via a hose. The outlet of the circulating water pump 44 is connected to a nozzle 32, which sprays circulating water. The inclined water tank 33 and the guide channel 331 collect the sprayed water and the drainage from the upper flat water tank 35, and discharge it from the lower end of the inclined water tank 33. The rear end of the lower flat water tank 35 collects the drainage from the lower end of the inclined water tank 33, and discharges it from the front end of the flat water tank 35, entering the next layer of inclined water tank 33, and finally flowing into the circulating water tank 25. At the same time, the spraying water from the nozzle 32 causes the air above the inclined water tank 33 to flow. Since there is a gap between the rear end of the inclined water tank 33, i.e., the lower end, and the back plate of the cement test block curing box 3, the air above the test mold support 34 can circulate through this gap.

[0053] The second objective of this invention is to provide a cement test block curing tank 2, such as... Figure 2 , Figure 5 , Figure 6As shown, the system includes a curing tank body with an insulation layer on its side walls, and the interior of the curing tank body is sealable; multiple circulating water tanks 22 are fixed to the curing tank body from top to bottom, and multiple drain outlets are provided on one side of the bottom of each circulating water tank 22. These drain outlets are connected to another circulating water tank 22 adjacent to the bottom of the first circulating water tank 22, and the axes of the drain outlets of adjacent circulating water tanks 22 are arranged in a staggered manner; a flow guide bracket 24 is fixedly installed inside the circulating water tank 22, and a flow guide channel is formed between the bottom of the flow guide bracket 24 and the inner bottom of the circulating water tank 22; a test block assembly is used to support cement test blocks. The test block assembly can be placed on the flow guide bracket 24, and the water in the circulating water tank 22 does not come into contact with the test block assembly; the end of the circulating water pool 25 away from the cement test block curing box 3 is located at the bottom of the curing pool body; the circulating water pool 25 is connected to the water inlet 21 at the top of the curing pool body through a pipeline connected to a circulating pump, and the water inlet 21 is connected to the uppermost circulating water tank 22, and the water in the bottommost circulating water tank 22 can fall into the circulating water pool 25; the circulating water pool 25 is connected to the above-mentioned temperature control module, which can regulate the temperature of the water in the circulating water pool 25. The test block assembly of this embodiment includes a water tank 23 with an open top. A test block support 231 is provided inside the water tank 23, on which a cement test block 7 is placed. The test block support 231 has partitions located on both sides of the cement test block 7. The height of the partitions is greater than the height of the cement test block 7 and also greater than the curing water level. The partitions have pre-filling water markings 5 ​​and curing water markings 6. In one embodiment, four vertically and parallel partitions are used, and multiple horizontally arranged bottom and side strips are used to connect the four partitions sequentially to form the test block support 231. A cement test block 7 is placed between two adjacent partitions, with the bottom of the cement test block 7 located on the bottom strip. The partitions, bottom strips, and side strips maintain the required spacing around the cement test block 7. The partitions and bottom of the test block support 231 both adopt a mesh structure, which facilitates heat exchange between the cement test block and the water in the water tank 23. The test block support 231 can be placed in or removed from the water tank 23 along with the cement test block, making operation convenient.

[0054] The bottom of the flow guide bracket 24 is provided with multiple partitions 241, which divide the circulating water tank 22 into multiple circulating water channels. Multiple drain outlets are located in different circulating water channels. In the cement test block curing pool 2, the temperature of the circulating water will fluctuate continuously when the temperature is adjusted. By increasing the height of the partitions 241, the depth of the circulating water channel in the circulating water tank 22 can be increased, and the pool 23 will be separated from the circulating water, so that the water temperature in the pool is not affected by the temperature adjustment of the circulating water.

[0055] The outlet of the circulating water tank 25 is connected to a circulating water pump 44 via a hose. This circulating water pump 44 is not the same as the circulating water pump 44 connected to the nozzle 32 inside the cement block curing box 3. The two circulating water pumps 44 are set up independently and will not interfere with each other's operation. The outlet of the circulating water pump 44 is connected to the inlet 21 at the top of the cement block curing tank 2. The circulating water enters the rear end of the top-level circulating water tank 22 through the inlet 21. The partition bar 241 includes short partition bars and long partition bars. The end of the long partition bar away from the inlet 21 is fixedly connected to the front side of the circulating water tank 22. Therefore, the long partition bar of the guide bracket 24 divides the circulating water into left and right parts. The short partition bars are distributed on the left and right sides of the long partition bar. The short partition bars are spaced from the front side of the circulating water tank 22, guiding the circulating water to flow through the front end of the circulating water tank 22, then turning around and being discharged through the drain outlet at the rear end of the circulating water tank 22, entering the next layer of circulating water tank 22, and finally being discharged into the circulating water tank 25.

[0056] During operation, first, add curing water to the water tank 23 according to the pre-filled water level line of the test block support 231. Then, push the water tank 23 into the upper part of the corresponding circulating water tank 22 along the guide support 24. After the water temperature reaches 20℃, pull out the water tank 23 and take out the test block support 231. Place the cement test block into the test block support 231 and put it into the water tank 23 together. The curing water level should just rise to the required curing water level line to avoid insufficient curing water level and to avoid excessive water spilling into the circulating water tank 22 and polluting the circulating water. Then, push the water tank 23 into the upper part of the corresponding circulating water tank 22 along the guide support 24 again for curing for the set time.

[0057] A third objective of this invention is to provide a cement test block curing system, such as... Figure 3 , Figure 4 As shown, the container includes a housing 1, which is equipped with a partition plate that divides the housing 1 into a first compartment and a second compartment. The first compartment is formed as a cement block curing box 3 as described above, and the second compartment is formed as a cement block curing pool 2 as described above. In one embodiment, an opening can be provided at the bottom of the partition plate to connect the circulating water pool 25 of the cement block curing box 3 and the cement block curing pool 2, that is, the two share a circulating water pool 25 to provide circulating water for the cement block curing box 3 and the cement block curing pool 2. A temperature control zone 4 is provided at the bottom of the housing 1, and a temperature control module is provided in the temperature control zone 4. A door 11 is hinged to one side of the first compartment and one side of the second compartment, and two symmetrically arranged temperature control zone doors 12 are hinged to one side of the temperature control zone 4.

[0058] In one embodiment, the temperature control module includes a temperature controller 41, a refrigeration unit 42, a cold water storage tank 43, a cooling water pump 45, and a circulating water pump 44. An electric heater 27 is installed inside the circulating water tank 25, and the cold water storage tank 43 is connected to the refrigeration unit 42. A temperature sensor 26 is installed on the top of the cement block curing chamber 3 or inside the circulating water tank 25, and the temperature sensor 26 is electrically connected to the temperature controller 41. The temperature controller 41 is electrically connected to both the electric heater 27 and the cooling water pump 45. The inlet 21 of the cooling water pump 45 is connected to the cold water storage tank 43 via a pipe, and the outlet of the cooling water pump 45 is connected to the circulating water tank 25 via a pipe. When the temperature controller 41 detects a low temperature through the temperature sensor 26, it activates the electric heater 27 to heat the circulating water in the circulating water tank 25 until it reaches 20°C. When the temperature controller detects a high temperature, it activates the cooling water pump 45 to add low-temperature water from the cold water storage tank 43 into the circulating water pool 25 until the temperature reaches 20°C. The evaporator of the refrigeration unit 42 is located inside the cold water storage tank 43. The refrigeration unit 42 operates according to its own schedule, unaffected by the constant temperature control of the circulating water, thus avoiding frequent start-ups and shutdowns of the refrigeration unit 42.

[0059] In one embodiment, a temperature control base plate 15 is provided in the temperature control zone 4, and the temperature control module is fixedly mounted on the temperature control base plate 15. Multiple detachable transport brackets 14 are connected to the temperature control base plate 15. The two ends of the transport brackets 14 are fixed to the mounting holes on the bottom side wall of the box 1 by screws. By installing the transport brackets 14, the box 1 and the temperature control base plate 15 become one unit, which facilitates the overall movement and transportation of the equipment. When in use, the transport brackets 14 are removed, the box 1 and the temperature control base plate 15 are separated, and the split structure is restored, so as to prevent the vibration of the refrigeration unit on the temperature control base plate 15 from being transmitted to the box 1.

[0060] In this embodiment, a door groove is provided on the outside of the temperature control zone door 12; after the two temperature control zone doors 12 are closed, the two door grooves are arranged coaxially, and after the temperature control zone doors 12 are closed, rod-shaped door bolts 13 can be placed in the two door grooves, so that the temperature control zone 4 is closed.

[0061] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
