Technical Field

[0001] The present invention relates to the technical field of concrete, and particularly relates to an integrated device for vacuum impregnation of phase change materials for concrete aggregates. Background Art

[0002] With the continuous growth of global energy consumption, the construction industry, as a major energy-consuming field, is facing increasingly severe energy conservation and environmental protection challenges. As one of the most commonly used materials in construction, the improvement of the performance of concrete is of great significance for improving building energy efficiency and environmental protection level; according to statistics, the energy consumption in the construction field accounts for 36% of the global total energy consumption, and the energy consumption of air conditioning systems accounts for 45%-50% of the building energy consumption. In recent years, phase change materials (PCMs) have been widely used in the modification of building materials due to their excellent thermal energy storage characteristics, especially by introducing PCMs into concrete aggregates through vacuum impregnation technology to optimize the performance of concrete.

[0003] A Chinese invention patent with the publication number CN113373631B, a step-by-step ring-shaped vacuum continuous impregnation production system, includes a closed housing, a ring-shaped production line and a rotating crane arranged in the closed housing.

Although this system can complete the impregnation work of materials, it cannot pre-treat the materials, resulting in a significant increase in the impregnation working time, and this system cannot quickly complete the feeding and discharging work, greatly reducing the practical effect; in the prior art, when mixing PCMs with concrete aggregates, pretreatment work is often not carried out on the concrete aggregates and PCMs, or the waiting time after pretreatment is too long, resulting in the concrete aggregates absorbing moisture in the air and affecting the mixing, and the material after impregnation cannot be taken out in time, greatly reducing the work efficiency.

The pretreatment assembly 3 also includes a control assembly installed on the processing assembly I for controlling the valve switch.

[0020] As Figure 1 , Figure 2 and Figure 3 shown in the figure, the support assembly 1 includes a support frame 101. A support plate 102 is fixedly installed on the support frame 101. An impregnation assembly 4 for stirring materials is fixedly installed on the support plate 102. A cooling assembly 5 for cooling materials is fixedly installed on the support frame 101. The cooling assembly 5 includes an outer box 501 fixedly installed on the vacuum tank 401. The outer box 501 wraps two-thirds of the vacuum tank 401. A cavity for the inflow of cooling water and the installation of the circulation pipe 202 is provided in the outer box 501. A water inlet pipe 503 for the entry of cooling water and a water outlet pipe 502 for the discharge of cooling water are fixedly installed on the outer box 501. The steam heating assembly 2 includes a circulation pipe 202 fixedly installed in the cavity part of the outer box 501. The circulation pipe 202 in the cavity of the outer box 501 surrounds the outer wall of the vacuum tank 401 for heating the inside of the vacuum tank 401. The circulation pipe 202 includes a lower half and an upper half. The lower half of the circulation pipe 202 is installed in the cavity of the outer box 501. An air inlet pipe 201 for the entry of steam and an air outlet pipe 203 for the discharge of steam are fixedly installed on the lower half of the circulation pipe 202. The steam heating assembly 2 further includes a temperature detector 401 installed on the vacuum tank 401 for detecting the internal temperature of the vacuum tank 401. A pretreatment assembly 3 for pretreating materials is installed on the impregnation assembly 4. The upper half of the circulation pipe 202 surrounds the pretreatment assembly 3 (as Figure 3As shown in the figure, the connection between the upper and lower parts of the circulation pipe 202 is composed of an input pipe and an output pipe. The steam in the lower part of the circulation pipe 202 enters the upper part of the circulation pipe 202 from the input pipe, and after completing the circulation, it returns to the lower part of the circulation pipe 202 through the output pipe; the vacuum assembly 6 includes a vacuum pump 601 and a pressure gauge 602. The pipeline of the vacuum pump 601 is communicated with the inside of the vacuum tank 401, and the pressure gauge 602 is fixedly installed on the vacuum tank 401 to detect whether the air pressure environment inside the vacuum tank 401 meets the standard.

[0021] During operation, the aggregates of concrete and the phase change material are respectively added to the pretreatment component 3, and the input amounts are respectively controlled by the detector I 313 and the detector II 331, so that the amount of the phase change material is 28%-35% of the mass of the concrete aggregates. After the materials are added, the manufacture of the vacuum impregnation environment is started. The steam manufactured by the steam generator is introduced into the circulation pipe 202 from the air inlet pipe 201, and the steam is made to circulate in the circulation pipe 202 by continuous input. After circulating once, it is discharged from the air outlet pipe 203 and returned to the steam generator for energy recovery. When the steam circulates, the inside of the vacuum tank 401 and the inside of the treatment barrel I 301 and the treatment barrel II 302 are heated, and the temperature is detected by the thermometer 204. Then, the steam temperature is controlled by the steam generator, and further the temperature inside the vacuum tank 401 and the inside of the treatment barrel I 301 and the treatment barrel II 302 is controlled. The concrete aggregates and the phase change material are pretreated by the pretreatment component 3. In cooperation with the steam heating component 2, the concrete aggregates are dried and added to the vacuum tank 401, and the phase change material is melted by the cooperation of the steam heating component 2. After the addition of the concrete aggregates is completed and the phase change material is melted, the phase change material is also added to the vacuum tank 401 by the pretreatment component 3. After the addition of the materials is completed, the vacuum component 6 is started to evacuate the air in the vacuum tank 401. At this time, the feed inlet is closed by the pretreatment component 3, so that the vacuum tank 401 is in a closed state. At the same time, the pretreatment component 3 starts a new round of feed pretreatment work. The vacuum degree in the vacuum tank 401 is controlled within the range of 0.08 MPa to 0.09 MPa by the vacuum component 6. After the preparation of the vacuum environment is completed, the concrete aggregates and the phase change material are stirred by the impregnation component 4 to make the distribution of the phase change material on the surface of the concrete aggregates uniform. After stirring evenly, cooling water is added to the outer box 501 through the water inlet pipe 503 to cool the vacuum tank 401. At this time, the vacuum component 6 stops working. During cooling, the impregnation component 4 keeps working and stirs the concrete aggregates and the phase change material. The cooling water in the outer box 501 is discharged through the water outlet pipe 502 and flows back to the cooling water manufacturing device for re-cooling and recycling. After the impregnation work is completed, the impregnated concrete aggregates are discharged by the impregnation component 4, and then the impregnation treatment of the concrete aggregates is completed. After the discharge work is completed, the above work is repeated to carry out the next round of impregnation treatment of the concrete aggregates.

This upward movement distance is set as the valve opening distance of the guide pipe 311, so that the concrete aggregates in the guide pipe 311 can fall into the vacuum tank 401 through the guide pipe 311. At the same time, when the moving plate 325 moves upward, it drives the pushing rack 321 to move upward, driving Rotating Shaft III 319 to rotate, and further driving the pushing cam 320 to rotate 90°. After the pushing cam 320 rotates 90°, it pushes Slide Valve I 314 and Slide Valve II 316 to move towards both ends, so that Slide Valve I 314 closes Feed Pipe I 305, and Slide Valve II 316 closes Feed Pipe II 306, preventing materials from entering Processing Barrel I 301 and Processing Barrel II 302. At this time, the limiting convex block of the pushing cam 320 cooperates with the pin block 323 to keep the pushing cam 320 restricted and stop rotating. At this time, the rack part of the pushing rack 321 also disengages from the gear on Rotating Shaft III 319. After Electric Cylinder I 324 completes the first-stage elongation, it remains stationary. Motor I 310 drives Gap Discharge Shaft 309 to rotate, enabling the concrete aggregates to enter the guide pipe 311 in a granular state and fall into the vacuum tank 401 through the guide pipe 311. At this time, the phase change material in Processing Barrel I 301 continues to be heated by the steam heating assembly 2 and starts to melt. After the phase change material in Processing Barrel I 301 melts completely, all the concrete aggregates in Processing Barrel II 302 have fallen into the vacuum tank 401.

[0026] The electric cylinder Ⅰ 324 extends for the second time, driving the stirring rod Ⅰ 308 to move upward again by a certain distance, and this upward distance is set as the distance of the valve opening of the treatment barrel Ⅰ 301. As a result, the melted phase change material in the treatment barrel Ⅰ 301 can fall into the guide pipe 311 through the valve opening of the treatment barrel Ⅰ 301, and then fall into the vacuum tank 401 through the guide pipe 311. At this time, the pushing cam 320 is kept fixed under the restriction of the latch block 323. After the phase change material in the treatment barrel Ⅰ 301 completely falls into the vacuum tank 401, the electric cylinder Ⅰ 324 starts to reset. The moving plate 325 resets under the action of the electric cylinder Ⅰ 324, causing the trigger rod to move downward. The trigger rod presses the pushing rod 322, and the pushing rod 322 presses the latch block 323 to move downward, so that the latch block 323 releases the restriction on the pushing cam 320. Then, the pushing cam 320 resets under the action of the torsion spring, and the sliding valve Ⅰ 314 and the sliding valve Ⅱ 316 reset under the action of the spring Ⅰ 315 and the spring Ⅱ 317. As a result, the feed pipe Ⅰ 305 and the feed pipe Ⅱ 306 can perform the next feeding. At the same time, the spring drives the connecting rope 326 to reset, the connecting frame 327 resets under the action of the spring Ⅲ 330, and the closing valve plate 328 also resets under the action of the spring, thus closing the guide pipe 311. Through the setting of the four guide pipes 311, the material can be divided into four parts and fall into the vacuum tank 401, accelerating the impregnation speed of the concrete aggregate and the phase change material. During reset, the stirring rod Ⅰ 308 resets under the action of the spring, closing the guide pipe 311 to ensure that the feed port of the vacuum tank 401 is in a closed state, thereby guaranteeing the impregnation environment of the concrete aggregate and the phase change material.

A rotating shaft IV 404 is rotatably installed on the installation frame 406. A frame-type stirring blade 405 for stirring the material is fixedly installed on the rotating shaft IV 404. A motor II 403 and a spline shaft 415 are fixedly installed on the rotating shaft IV 404. The output shaft of the motor II 403 is fixedly installed with the rotating shaft IV 404. The motor II 403 is fixedly installed with the support plate 102. The discharging assembly includes a material guiding plate 411 fixedly installed on the vacuum tank 401.

The vibration assembly includes a rotating toothed ring 412 rotatably installed on the discharging assembly. A plurality of pushing blocks (the number is set according to requirements) are circularly arranged on the rotating toothed ring 412. A plurality of knocking slide rods 413 (the number is set according to requirements) are slidably installed on the material guiding plate 411. The plurality of knocking slide rods 413 are circularly arranged with the material guiding plate 411. Springs are provided on the knocking slide rods 413. One end of the spring on the knocking slide rod 413 is fixedly installed with the knocking slide rod 413, and the other end is fixedly installed with the discharging assembly.

The helical gear at one end meshes with the helical gear on the rotating shaft V 407, and the helical gear at the other end intermittently meshes with the helical gear I 416.

[0028] When the material in the vacuum tank 401 needs to be processed during operation, the motor II 403 starts, which drives the rotating shaft IV 404 to rotate, and then stirs the material in the vacuum tank 401. At this time, the sealing plug 410 seals the vacuum tank 401. After the impregnation treatment is completed and the material needs to be taken out, the motor II 403 stops. At this time, the vacuum tank 401 is started, driving the moving frame 409 to move downward, which drives the sealing plug 410 to move downward, thus opening the discharge port of the vacuum tank 401. Then, in cooperation with the rotating frame-type stirring blade 405, the material falls into the guide tray 411 and through the guiding groove of the guide tray 411 into the discharge pipe 414, and is discharged through the discharge pipe 414, thus completing the work of taking out the material. At the same time, when the moving frame 409 moves downward, it drives the spline sleeve shaft 417 to move downward, so that the spline shaft 415 meshes with the spline sleeve shaft 417. At this time, the motor II 403 is started again, so that the spline sleeve shaft 417 drives the helical gear I 416 to rotate. At this time, the helical gear I 416 meshes with the helical gear of the rotating shaft VI 408, driving the rotating tooth ring 412 to rotate, and then the pushing block of the rotating tooth ring 412 intermittently pushes the knocking slide bar 413 to knock the vacuum tank 401, and in cooperation with the rotating frame-type stirring blade 405, the material can fall out quickly, avoiding the accumulation of the material.
