Description

Technical Field

[0001] The utility model relates to the technical field of autoclaves, in particular to a regenerated concrete autoclave with an autoclaved aeration structure. Background Technique

[0002] An autoclave, also known as a steam curing kettle or autoclave, is a large pressure vessel with a large volume and heavy weight. Autoclaves are widely used in production projects that require pressure steam curing processes, such as aerated concrete blocks, concrete pipe piles, lime-sand bricks, coal ash bricks, micro-porous calcium silicate boards, textile industry, and military industry.

[0003] During the autoclaving process of materials, it may be necessary to supplement air to the autoclaving device due to problems such as equipment aging and material properties. If air is directly supplemented, it may cause further leakage of the gas inside the device due to the large pressure difference between the air supplement device and the internal pressure of the device, and even lead to an explosion. Moreover, if the device is opened before the internal pressure is completely balanced, a large amount of steam inside the device may leak out. Content of the Utility Model

[0015] (III) Beneficial effects

[0016] The utility model provides a autoclave for recycled concrete with a steam pressure addition structure, which has the following beneficial effects:

[0017] 1. For the autoclave for recycled concrete with a steam pressure addition structure, during the process of the auxiliary pressure pipe sliding towards the inner connection disc, the air compression disc presses the gas in the gas addition pipe into the gas supply pipe through the inner connection disc. During the pressing process, the gas jacks up the torsion spring plate in the gas supply pipe. After the pressing is completed, the torsion spring of the torsion spring plate drives the square plate to cover the opening of the inner connection disc. At this time, when the air compression disc slides outwards, the gas outside the device passes through the auxiliary pressure pipe to push open the torsion spring plate outside the air compression disc and enters the gas addition pipe, achieving the purpose of isolating and supplementing air for steam pressure, and avoiding the problem that direct air supplementation may cause explosion due to excessive internal and external air pressure differences.

For the autoclave for recycled concrete with a steam pressure addition structure, the square plate of the blocking rod is jacked against the feeding disc by the air pressure in the circulation pipe, so that the sealing plate cannot slide when it slides to be blocked by the blocking rod. When the pressure relief is completely completed, the blocking rod is pushed into the circulation pipe. At this time, the sealing plate is slid open to take out the materials inside, achieving the purpose of automatically locking the outlet of the device and solving the problem that steam may leak if the device is opened before the pressure relief is completed.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] An autoclave for autoclaved aerated recycled concrete with an autoclaving and gas adding structure is provided in an embodiment of the present utility model. As Figures 1-4 shown, it includes a circulation pipe 1. The circulation pipe 1 is a circular pipe. One end of a circular rod is fixedly connected to a circular disk. The outer surface of the circular disk is provided with circular holes penetrating through to the circular pipe. The inner surface of the circular holes is fixedly connected to a pressure relief valve 20. A through hole is provided at the center position of the circular disk. The inner surface of the through hole is rotatably connected to a drainage fan 19. Two groups of circular holes are provided on the outer circumferential surface of the circular pipe. The inner surface of one side circular hole is fixedly connected to a liquid injection pipe 16, and the inner surface of the other side circular hole is fixedly connected to an air supply pipe 6. The circulation pipe 1 is used to guide the steam flowing therein, and at the same time protect and support the main structure of the device.

[0026] One end of the circulation pipe 1 is fixedly connected to a feeding tray 2. A clamping plate buckle 3 is fixedly connected inside the outer surface of the feeding tray 2 away from the circulation pipe 1. A sealing plate 4 is slidably connected to the inner surface of the clamping plate buckle 3. A blocking rod 5 is slidably connected to the outer surface of the sealing plate 4. The blocking rod 5 is a circular rod. The outer circumferential surface of the circular rod is slidably connected to the feeding tray 2, and the outer circumferential surface of the circular rod is slidably connected to the sealing plate 4. A square plate is fixedly connected to the outer surface of the circular rod near the pressure relief valve 20. The blocking rod 5 is used to block the sealing plate 4 so that the sealing plate 4 cannot be opened when the air pressure in the circulation pipe 1 is too high.

[0027] A feeding tray 2 is slidably connected to the outer surface of the blocking rod 5. An air supply pipe 6 is fixedly connected to the inner surface of the circulation pipe 1. The air supply pipe 6 is a rectangular pipe with circular holes at both ends.

[0028] An air vent valve 7 is fixedly connected to the inner surface of the air supply pipe 6. A torsion spring plate 8 is fixedly connected to the inner surface of the air vent valve 7. The torsion spring plate 8 consists of two circular rods. Torsion springs are fixedly connected to the outer circumferential surfaces of the circular rods.

One of the circular rods is fixedly connected to the inner wall of the air supply pipe 6 at both ends, and the outer circumferential surface of the other circular rod is fixedly connected to a pressure air disc 11. The torsion spring plate 8 in the air supply pipe 6 can block the circular hole of the internal connection plate 9, enabling the air in the internal connection plate 9 to enter the air supply pipe 6. Due to the blockage of the inner wall of the air supply pipe 6, the air in the air supply pipe 6 will not be sent into the internal connection plate 9. The torsion spring plate 8 fixed to the outside of the pressure air disc 11 can pour the air in the auxiliary pressure pipe 12 into the gas adding pipe 10, and at the same time, the blockage of the pressure air disc 11 prevents the air in the gas adding pipe 10 from flowing into the auxiliary pressure pipe 12.

[0029] An internal connection plate 9 is fixedly connected to one end of the air supply pipe 6 away from the air vent valve 7. A gas adding pipe 10 is fixedly connected to the outer surface of the series connection plate 9 away from the air vent valve 7.

The pressure air disc 11 is a circular disc with a circular hole at the center of the disc. An auxiliary pressure pipe 12 is fixedly connected to the inner surface of the circular hole. The outer circumferential surface of the circular disc is slidably connected to the inner wall of the gas adding pipe 10. There are two annular blocks on the outer surface of the circular disc close to the air vent valve 7, and a torsion spring plate 8 is fixedly connected to the inner surface of the annular blocks. The pressure air disc 11 is used to fix the torsion spring plate 8 and prevent the torsion spring plate 8 from rotating towards the auxiliary pressure pipe 12.

[0030] A torsion spring plate 8 is fixedly connected to the outer surface of the pressure air disc 11 close to the air vent valve 7. An auxiliary pressure pipe 12 is connected through the outer surface of the pressure air disc 11 away from the air vent valve 7. A connecting pipe column 13 is fixedly connected to the inner surface of the circulation pipe 1. A steam material pipe 14 is fixedly connected to the outer surface of the connecting pipe column 13 away from the circulation pipe 1. The steam material pipe 14 is a circular pipe. The outer circumferential surface of the circular pipe is fixedly connected to the connecting pipe column 13. A blowing air disc 17 is fixedly connected to one end of the circular pipe away from the feeding tray 2. A material placement plate 15 is fixedly connected to the inner wall of the circular pipe. There is a circular hole on the outer circumferential surface of the circular pipe away from the air supply pipe 6, and a liquid injection pipe 16 is fixedly connected to the inner surface of the circular hole. The steam material pipe 14 is used to provide necessary conditions for steam circulation, provide space for placing materials, and provide a necessary working environment for some devices.

[0031] A material placing plate 15 is fixedly connected to the inner surface of the steaming material pipe 14, a liquid injection pipe 16 is fixedly connected to the inner surface of the steaming material pipe 14, a circulation pipe 1 is fixedly connected to the outer circumferential surface of the liquid injection pipe 16, an air supply plate 17 is fixedly connected to the end of the steaming material pipe 14 away from the feeding plate 2, a fan support frame 18 is fixedly connected to the outer surface of the air supply plate 17 away from the steaming material pipe 14, a drainage fan 19 is rotatably connected to the inner surface of the fan support frame 18, and the circulation pipe 1 is rotatably connected to the outer circumferential surface of the drainage fan 19. The drainage fan 19 is a circular rod, and the outer circumferential surface of the circular rod is rotatably connected to the fan support frame 18, and the outer circumferential surface of the circular rod is rotatably connected to the circulation pipe 1, and the outer circumferential surface of the circular rod is fixedly connected to fan blades, and the outer surface of the fan blades away from the circular rod is slidably connected to the air supply plate 17, the drainage fan 19 guides the airflow inside the device to steam and pressurize the material, and a pressure relief valve 20 is fixedly connected to the inner surface of the drainage fan 19.

[0032] Working principle: Use the device to connect the liquid pipeline with the liquid injection pipe 16, and connect the gas pipeline with the ventilation valve 7, and place the material to be autoclaved on the material placement plate 15, then close the sealing plate 4 for autoclaving. If air needs to be replenished during the autoclaving process, the auxiliary pressure pipe 12 can be driven by an external power source to slide back and forth. When the auxiliary pressure pipe 12 slides toward the inner plate 9, the air compressor 11 presses the gas in the gas filling pipe 10 into the air delivery pipe 6 through the inner plate 9. During the pressing process, the gas lifts the torsion spring plate 8 in the air delivery pipe 6. After the pressing is completed, the torsion spring of the torsion spring plate 8 drives the square plate The opening of the inner disk 9 is covered. At this time, when the air compression disk 11 slides outward, the gas outside the device pushes the torsion spring plate 8 outside the air compression disk 11 through the auxiliary pressure pipe 12 and enters the gas filling pipe 10, so that the device is replenished with air back and forth. When the steam pressing is completed, the pressure is relieved through the pressure relief valve 20. When the pressure relief is not completed, the air pressure in the circulation pipe 1 will push the square plate of the resistance rod 5 to the feeding plate 2, so that the sealing plate 4 cannot slide when it slides to the resistance rod 5. When the pressure relief is completely completed, the resistance rod 5 is pushed to slide into the circulation pipe 1. At this time, the sealing plate 4 is slid open to take out the material inside.
