Description

Technical Field

[0001] This invention relates to the field of CT internal temperature control, specifically a CT internal temperature control and steam replenishment test device. Background Technology

[0002] Water vapor migration accounts for more than 15% of water migration in coarse-grained soil frost heave, which is a significant proportion. However, the testing technology is not perfect, and existing coarse-grained soil freezing tests and coarse-grained soil CT scan tests are conducted separately. Most studies are CT scans of coarse-grained soil before and after freezing, and CT scans at various freeze-thaw time points. Due to instrument limitations, there is a lack of continuous real-time scanning conditions, and the control of water vapor migration amount, external interference (the influence of ambient humidity), and water vapor density (migration rate) is inaccurate. Most experiments involve replenishing steam from the top or bottom, and the steam replenishment is uneven due to gravity. In addition, the water used in existing steam replenishment humidifiers is usually unfiltered, which affects the quality of subsequent steam replenishment.

[0003] Therefore, a CT internal temperature control and steam replenishment test device is proposed to address the above problems. Summary of the Invention

The design integrates bottom temperature control and water replenishment, and mold and steam replenishment, which is beneficial for controlling the amount of water replenishment, reducing external interference, and ensuring uniform steam replenishment. The amount of water replenishment can be calculated by measuring the liquid change in the Marshall water replenishment bottle, and the amount of steam replenishment can be calculated by measuring the difference between the water change in the humidifier and the water volume in the water collection device connected to the mold, thus completing the separate measurement of water replenishment and steam replenishment. It can be applied to soil samples with 0.075-5mm particles, improving the problems existing in the freezing test of coarse-grained soil, including the lack of real-time scanning function, complex temperature control of the CT device, poor connection between water replenishment and steam replenishment, uneven steam replenishment, and high cost.

[0015] 2. This invention filters water using a filter rack. Activated carbon inside the mounting box adsorbs harmful substances in the water, preventing impurities from affecting the quality of subsequent steam replenishment. A brush plate repeatedly cleans the filter rack, and a high-frequency tapping bar shakes impurities off the rack, which then fall into a storage box for collection. This effectively avoids the problem of excessive impurities accumulating on the filter rack after prolonged use, thus reducing the need for frequent manual cleaning and significantly lowering the workload for workers.

[0027] Example 1

[0028] Please see Figure 1-3 As shown, a CT internal temperature control and steam replenishment test device includes a base 1, a base 2 mounted on top of the base 1, a soil sample mold body 3 mounted on top of the base 2, a PVC insulation film 4 detachably connected to the outside of the soil sample mold body 3, a temperature control box 5 installed on one side of the top of the base 1, a base plate 6 installed at the bottom of the base 2, a top plate 7 installed on the top of the soil sample mold body 3, a Mascherano replenishment bottle 12 installed on the top side of the base 1 near the base 2, and a steam replenishment assembly installed on one side of the top of the base 1.

[0031] Please see Figure 4-8As shown in the first embodiment, as another implementation of the present invention, a water inlet 22 is fixedly connected to the upper part of one side of the filter box 11. A connecting pipe 23 is fixedly connected between the filter box 11 and the humidifier 9. A solenoid valve 24 is installed inside the connecting pipe 23. An installation box 21 is fixedly connected inside the filter box 11 and below the filter frame 15. Activated carbon is placed inside the installation box 21. An opening and closing door 37 is installed on the outside of the installation box 21. A filter assembly is placed inside the filter box 11. A door is installed on the upper part of the inside of the filter box 11. The filter assembly includes a vibrating component and a filter frame 15. The filter frame 15 is mounted on the upper part of the filter box 11 via a sealing plate. A rotating shaft 16 is rotatably connected to the top of the filter box 11. Brush plates 17 are symmetrically fixedly connected to the bottom of the rotating shaft 16 inside the filter box 11. A storage box 19 is detachably connected to the bottom of the filter frame 15. The vibrating component includes striking rods 20 and a linkage unit. The striking rods 20 are slidably connected to both sides of the top of the filter box 11. A motor 25 is fixedly connected to the top of the filter box 11 via a mounting bracket. The output end of filter 25 is fixedly connected to a first bevel gear 26. Rotating rods 27 are rotatably connected to both sides of the top of filter box 11 via limit blocks. A second bevel gear 28 is fixedly connected to one end of each rotating rod 27. The first bevel gear 26 meshes with each of the two second bevel gears 28. An eccentric wheel 29 is fixedly connected to the end of each rotating rod 27 away from the second bevel gear 28. A sliding shaft 30 is fixedly connected to the outer side of each of the two eccentric wheels 29. A limit plate 31 is fixedly connected to the top of each of the two striking rods 20. The two sliding shafts 30 are respectively... The brush plate 17 is slidably connected to the inside of the corresponding limiting plate 31. The brush plate 17 can be rotated by the linkage unit. The linkage unit includes a connecting rod. A connecting plate is fixedly connected between the two brush plates 17. The output end of the motor 25 is fixedly connected to the rotating shaft 16. The bottom of the rotating shaft 16 is fixedly connected to the connecting plate. The bottom of the filter frame 15 is fixedly connected to the discharge port 18. The discharge port 18 is symmetrically provided with L-shaped grooves 34. The inner side of the storage box 19 is symmetrically fixedly connected with the locking block 35 that cooperates with the L-shaped groove 34. An isolation net 36 is provided inside the storage box 19.

[0032] During operation, water can be injected into the filter box 11 through the inlet 22. The water source can be filtered through the filter frame 15. The activated carbon in the mounting box 21 can adsorb harmful substances in the water, preventing impurities in the water from affecting the quality of the subsequently added steam. The motor 25 is started, driving the first bevel gear 26 and the rotating shaft 16 to rotate. The rotating shaft 16 drives the brush plates 17 on both sides to rotate, cleaning the impurities isolated on the top of the filter frame 15. The first bevel gear 26 drives the two second bevel gears 28 and the eccentric wheel 29 to rotate through meshing, so that the eccentric wheel 29 drives the sliding shaft 30 to slide within the corresponding limiting plate 31, thereby pushing the limiting plate 31 and the striking rod 20 to perform high-frequency reciprocating motion. The striking rod 20 drives the bottom slider 32 to strike the filter frame 15 at high frequency, causing it to vibrate and knocking down the impurities above the filter frame 15. Then, they fall into the storage box 19 through the discharge port 18 for collection. When the impurities need to be processed, The water in the filter box 11 is drained. After opening the box door 39, the storage box 19 is rotated clockwise, causing the locking block 35 to slide inside the L-shaped groove 34. The storage box 19 can then be pulled down to disassemble it. After removal, the impurities inside can be centrally processed. The activated carbon inside the mounting box 21 can be replaced by opening the opening and closing door 37. This device can filter the water source through the set filter frame 15. The activated carbon in the mounting box 21 can adsorb harmful substances in the water, preventing impurities in the water from affecting the quality of the subsequent steam replenishment. The filter frame 15 can be repeatedly cleaned by the brush plate 17. With the high-frequency tapping of the tapping rod 20, the impurities on the filter frame 15 are knocked off and then fall into the storage box 19 through the discharge port 18 for collection. This effectively avoids the problem that the filter frame 15 will easily affect the filtration effect due to excessive accumulation of impurities after long-term use. Frequent manual cleaning is not required, which effectively reduces the labor burden of the staff.

[0033] A rubber ring 38 is fixedly connected between the sealing plate and the filter frame 15. A door 39 is installed on the outside of the filter box 11. A slider 32 is slidably connected to the bottom of each of the two striking rods 20. A spring 33 is provided between the inside of the slider 32 and the striking rod 20.

[0034] Through the above technical solution, when the striking rod 20 strikes the filter frame 15, the spring 33 can be repeatedly compressed, causing it to deform and increasing the impact force of the slider 32 on the filter frame 15, thereby effectively improving the vibration effect of the filter frame 15.

[0035] Working principle: The temperature control box 5, together with two temperature control pipes 8, can supply temperature-controlled water to the bottom plate 6 and the top plate 7 respectively. Cold water is supplied when cooling is needed, and hot water is supplied when heating is needed. The humidifier 9 can supply steam to the soil sample mold body 3 through the steam injection pipe 10. The soil sample mold body 3 can be replenished with water through the Marshall water injection bottle 12. By using a PVC insulation film 4 to cover the outside and working together with the temperature control box 5 to control the temperature, the system temperature can be accurately controlled. The design integrates bottom temperature control and water injection, and mold and steam replenishment, which is conducive to controlling the amount of water replenishment, reducing external interference, and ensuring uniform steam replenishment. The amount of water replenishment can be counted by measuring the liquid change in the Marshall water injection bottle 12. The amount of steam replenishment can be counted by measuring the difference between the water change in the humidifier 9 and the water volume in the water collection device connected to the soil sample mold body 3. The water replenishment and steam replenishment are measured separately. This solution adopts a modular design of external humidifier 9 and temperature control box 5, which can realize rapid maintenance and preparation, and improve the efficiency of test preparation by more than 40%.It integrates temperature gradient control and heat preservation water vapor compensation functions, supports high-definition real-time CT scanning of the coarse-grained soil freezing process, and allows water to be injected into the filter box 11 through the water inlet 22. The water source can be filtered through the set filter frame 15, and the activated carbon in the mounting box 21 can adsorb harmful substances in the water to prevent impurities in the water from affecting the quality of subsequent steam replenishment. The motor 25 is started, which drives the first bevel gear 26 and the rotating shaft 16 to rotate. The rotating shaft 16 drives the brush plates 17 on both sides to rotate, cleaning the impurities isolated on the top of the filter frame 15. The first bevel gear 26... 6. The meshing relationship drives the two second bevel gears 28 and the eccentric wheel 29 to rotate, causing the eccentric wheel 29 to drive the sliding shaft 30 to slide within the corresponding limiting plate 31. This pushes the limiting plate 31 and the striking rod 20 to perform high-frequency reciprocating motion. The striking rod 20 drives the bottom slider 32 to strike the filter frame 15 at high frequency, causing it to vibrate and knocking off the impurities above the filter frame 15. These impurities then fall into the storage box 19 through the discharge port 18 for collection. When impurities need to be processed, the water in the filter box 11 is drained, and the filter is opened. After opening the door 39, rotate the storage box 19 clockwise to allow the locking block 35 to slide inside the L-shaped groove 34. Pulling down the storage box 19 allows for disassembly and removal of the internal impurities for centralized processing. Opening the opening door 37 allows for replacement of the activated carbon inside the mounting box 21. This device filters the water source via the filter frame 15. The activated carbon in the mounting box 21 adsorbs harmful substances in the water, preventing impurities from affecting the quality of subsequent steam replenishment. The filter frame 15 can be repeatedly cleaned using the brush plate 17. The high-frequency striking of the striking rod 20 knocks down the impurities above the filter frame 15, which then fall into the storage box 19 through the discharge port 18 for collection. This effectively avoids the problem that excessive accumulation of impurities after prolonged use of the filter frame 15 can affect the filtration effect. It eliminates the need for frequent manual cleaning, effectively reducing the workload of the staff. When the striking rod 20 strikes the filter frame 15, it can repeatedly compress the spring 33, causing it to deform and increase the impact force of the slider 32 on the filter frame 15, thereby effectively improving the vibration effect of the filter frame 15.
