Description

Technical Field

[0001] The utility model relates to the technical field of autoclaves, in particular to an autoclave. Background Art

[0002] The autoclave is a crucial piece of equipment in the production of calcium silicate board. Saturated steam is introduced into the autoclave to raise the pressure of the saturated steam inside the autoclave to over 0.8 MPa and the temperature to over 170°C. This creates an ideal environment for the slab to react chemically with the siliceous and calcium materials in the autoclave to produce high-strength, structurally stable calcium silicate hydrate. The saturated steam continuously liquefies in the autoclave, generating a large amount of condensed water. This condensed water is then discharged directly into the ditch below the autoclave through the autoclave bottom steam trap and drain valve. The condensed water in the ditch is then collected in a pit next to the autoclave and pumped back to the production line for reuse. Currently, most companies use this method to easily and intuitively detect abnormalities such as leaks or non-drainage.

[0003] However, after the calcium silicate board is autoclaved and cured in the autoclave, it is necessary to stop supplying steam to the autoclave and allow the steam in the autoclave to cool naturally. When the steam temperature and pressure in the autoclave drop to a certain level, the exhaust equipment is started to extract the steam in the autoclave and reduce the pressure to zero or negative pressure. Then, the autoclave cover is opened to take out the calcium silicate slab, thereby preventing the overflow of high-temperature steam and avoiding burns to the operators.

[0004] The reason why the steam in the autoclave is allowed to cool naturally instead of directly starting the exhaust equipment to extract the steam in the autoclave is that when the steam temperature and pressure in the autoclave are high, immediately starting the exhaust equipment to quickly reduce the pressure will cause greater stress on the structure of the autoclave, accelerating equipment aging and even causing equipment damage; natural cooling can reduce this stress. In addition, if the autoclave is directly exhausted under high temperature and high pressure, the steam will quickly condense into water, causing water hammer, that is, the instantaneous pressure surge caused by the liquid impacting the pipeline and equipment, causing damage to the equipment; the temperature and pressure drop after natural cooling can reduce this risk; but during the natural cooling process, the steam temperature and pressure begin to drop, which is a relatively slow process. Although it can reduce the damage to the equipment, natural cooling will extend the entire production cycle, thereby reducing production efficiency.

[0005] In view of this, in order to overcome the above technical problems, the utility model proposes an autoclave to solve the above technical problems. Utility Model Content

[0032] After the calcium silicate board is autoclaved and cured in the existing autoclave, it is necessary to stop supplying steam to the autoclave first and allow the steam in the autoclave to cool naturally. When the steam temperature and pressure in the autoclave drop to a certain level, the exhaust equipment is started to extract the steam in the autoclave and reduce the pressure to zero or negative pressure. Then, the autoclave cover 11 is opened to take out the calcium silicate slab. However, during the natural cooling process, the steam temperature and pressure begin to drop. This is a relatively slow process. Although it can reduce damage to the equipment, the natural cooling process will extend the entire production cycle, thereby reducing production efficiency.

[0033] In this regard, the utility model arranges the push plate 22 and the vortex tube 16 so that the push plate 22 can push the steam entering the mounting shell 2 to flow into the vortex tube 16, so that the steam flowing into the vortex tube 16 is compressed and releases heat. After the steam in the vortex tube 16 releases heat, the control airway 161 is opened, so that the cooled gas in the vortex tube 16 is transported to the kettle body 1, and this is repeated, thereby ensuring the stability of the air pressure in the kettle body 1 while reducing the temperature of the steam in the kettle body 1, not only avoiding damage to the equipment caused by excessively rapid changes in air pressure; but also accelerating the decrease in the steam temperature in the kettle body 1, thereby shortening the cooling cycle, and improving the maintenance and production efficiency of the calcium silicate board of the utility model;

[0034] In the initial state, the air inlet 14 on one side of the kettle body 1 is connected to the external steam pipe, and the electromagnetic plate 172 is in the power-off state. At this time, the bevel gear shaft 136 is inserted into the card slot 173 on the side of the spur gear 134. Then the user first controls the electromagnetic block 183 to energize, so that the energized electromagnetic block 183 can attract the blocking block 181 and squeeze the supporting spring 182 into the groove 18, so that the blocking block 181 entering the groove 18 is away from the spur gear 134; then control the driving motor 131 to operate, so that the output shaft of the driving motor 131 drives the bevel gear shaft 136 to rotate, so that the bevel gear shaft 136 drives the spur gear 134 to rotate, so that the spur gear 134 can drive the connecting gear 133 to rotate through the transmission gear 132 meshing with it, so that the connecting gear 133 drives the rotating rod 111 fixed thereto to rotate, so that the rotating rod 111 drives the kettle cover 11 fixed thereto to rotate upward, so that the feed port 12 on one side of the kettle body 1 is opened; at this time, the user The operator pushes the mounting bracket 13 equipped with the calcium silicate board to be cured into the kettle body 1 through the feed inlet 12 of the kettle body 1; then controls the driving motor 131 to rotate in the opposite direction, so that the driving motor 131 can drive the rotating rod 111 to drive the kettle cover 11 to rotate downward until the kettle cover 11 contacts the kettle body 1, so that the kettle cover 11 blocks and seals the feed inlet 12 of the kettle body 1; at this time, controls the electromagnetic block 183 to be de-energized, so that the blocking block 181 is no longer affected by the adsorption effect of the electromagnetic block 183, so that the blocking block 181 can extend out of the groove 18 under the push of the restoring force of the supporting spring 182 and be inserted between the two teeth of the spur gear 134, so that the blocking block 181 is meshed with the spur gear 134; at this time, the blocking block 181 and the spur gear 134 produce a blocking effect, preventing the rotating rod 111 from driving the spur gear 134 to rotate; then controls the external steam delivery pipeline to deliver high-temperature steam into the kettle body 1 through the air inlet 14; thereby realizing autoclave curing of the calcium silicate board in the autoclave;

[0035] After the autoclave curing is completed, the external steam delivery pipeline is first controlled to stop delivering high-temperature steam into the kettle body 1, and then the electromagnetic sheet 172 is controlled to be energized, so that the electromagnetic sheet 172 adsorbs the bevel gear shaft 136 and squeezes the connecting spring 171 into the rectangular groove 17; the bevel gear shaft 136 is continuously moved in the direction close to the bevel gear ring 135, so that the bevel gear shaft 136 extends out of the slot 173 and moves away from the spur gear 134, until the bevel gear shaft 136 contacts and meshes with the bevel gear ring 135. At this time, the drive motor 131 is controlled to run, so that the drive motor 131 can drive the bevel gear ring 135 to rotate through the bevel gear shaft 136, so that the bevel gear ring 135 Drives the screw rod 21 connected thereto to rotate; in the initial state, the push plate 22 is located at one end of the mounting shell 2 close to the vortex tube 16; therefore, when the screw rod 21 rotates, it can drive the push plate 22 to move in the direction close to the kettle cover 11, so that the push plate 22 pushes the bellows 23 close to one side to compress, so that the gas in the bellows 23 is compressed. At the same time, the high-temperature steam in the kettle body 1 will enter the bellows 23 through the air hole 15; as the pressure of the compressed gas in the bellows 23 gradually increases, the pressure difference on both sides of the sealing block 26 continues to decrease, until the pressure on the side of the sealing block 26 close to the bellows 23 is larger, and the compressed gas will push the sealing The block 26 stretches the tower-shaped spring 261 and extends out of the through groove 24, so that the gas in the bellows 23 can enter the mounting shell 2 of the push plate 22 away from the bellows 23 through the through groove 24, until the bellows 23 is compressed to the maximum. At this time, the drive motor 131 stops running. At this time, the air pressure on both sides of the push plate 22 is stable. At this time, the sealing block 26 is no longer pushed by the pressure difference, so that the sealing block 26 can enter the through groove 24 under the pull of the tower-shaped spring 261, so that the sealing block 26 in the through groove 24 is sealed. Then the drive motor 131 is controlled to rotate in the opposite direction and drive the push plate 22 to move in the direction close to the vortex tube 16. At this time, the solenoid valve 25 in the airway 161 is closed. The push plate 22 is in a closed state, while the solenoid valve 25 in the exhaust port 231 is in an open state. As the push plate 22 continues to approach the vortex tube 16, the high-temperature steam in the kettle body 1 is compressed and enters the vortex tube 16, and the bellows 23 is stretched and extended, so that the external gas flows back into the bellows 23 through the exhaust port 231; the high-temperature steam entering the vortex tube 16 is compressed, so that the internal energy inside is released in the form of heat energy, that is, the high-temperature steam in the vortex tube 16 conducts heat out through the tube wall of the vortex tube 16. Because the vortex tube 16 is made of copper material, the vortex tube 16 has good thermal conductivity, thereby accelerating the heat dissipation effect of the steam in the vortex tube 16;When the steam in the vortex tube 16 dissipates heat to a specified temperature, the solenoid valve 25 in the air passage 161 is controlled to open, allowing the high-pressure gas in the vortex tube 16 to flow back into the kettle body 1 through the air passage 161. After the low-temperature, high-pressure gas in the vortex tube 16 enters the kettle body 1, its pressure is released. At this time, the gas expands and exchanges heat with the high-temperature gas in the kettle body 1, thereby accelerating the cooling of the high-temperature gas in the kettle body 1. Subsequently, the drive motor 131 is controlled again to drive the push plate 22 to move closer to the kettle cover 11 via the screw rod 21, thereby performing a new round of steam heat dissipation.

[0036] It can be seen from the ideal gas state equation that the pressure of the gas is proportional to the temperature. Therefore, as the temperature of the steam in the kettle body 1 drops, the air pressure in the kettle body 1 will continue to decrease. In order to prevent the air pressure from decreasing too quickly, which will cause greater stress on the structure of the autoclave, accelerate the aging of the equipment, and even cause damage to the equipment; the utility model provides a bellows 23, so that the bellows 23 can continuously transport external air into the mounting shell 2 under the extrusion of the push plate 22. On the one hand, it can transport gas into the kettle body 1, thereby reducing the change of air pressure in the kettle body 1, avoiding damage to the kettle body 1 and other equipment caused by excessively rapid changes in air pressure inside the kettle body 1, and improving the service life of the kettle body 1; on the other hand, the bellows 23 transports external low-temperature gas into the kettle body 1, thereby improving the heat exchange effect of the steam in the kettle body 1, thereby accelerating the cooling rate of the steam in the kettle body 1, shortening the steam cooling cycle, and improving the maintenance production efficiency of the calcium silicate board of the utility model.
