Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete production equipment technology, specifically to a concrete block autoclave. Background Technology
[0002] In the production process of concrete blocks, the autoclave is a key piece of equipment. It uses high-temperature and high-pressure steam to cure the concrete blocks, thereby improving their strength and durability. In the prior art, the device with patent number CN202321239857.X includes an autoclave body with an autoclave chamber and a door hinged to it. The device drives an arc-shaped block to slide towards the door through a drive component, placing absorbent cotton between the autoclave chamber and the door. Then, the door is detached from the autoclave chamber by a control device. The high-temperature steam is absorbed by the absorbent cotton and condensed by the condensation beads inside the absorbent cotton, thereby reducing the release of high-temperature steam.
[0003] However, the device has some shortcomings in use. On the one hand, the steam flow inside the autoclave is not smooth enough, resulting in uneven heating of the concrete blocks and affecting the curing effect. On the other hand, the steam generated during the autoclaving process is often directly discharged, which not only wastes energy but may also cause some pollution to the environment. In addition, the sealing and protection performance of the autoclave door needs to be further improved to ensure the safety of operation and the autoclaving effect.
[0004] Based on the above, there is a need for a concrete block autoclave that can facilitate steam flow, enable steam recovery and reuse, and provide good protection. Utility Model Content

[0024] As attached Figure 1 To be continued Figure 6 The aforementioned is a concrete block autoclave, comprising an autoclave body 1, a protective mechanism 2, and a steam recovery assembly 3.
[0025] Example 1
[0026] Specifically, the autoclave body 1 includes an autoclaving chamber 11, an annular groove 12 is provided at one end of the autoclaving chamber 11, support feet are symmetrically provided at the bottom end of the autoclaving chamber 11, an exhaust pipe 16 is provided at the top end of the autoclaving chamber 11, the exhaust pipe 16 extends through to the inner wall of the autoclaving chamber 11, a limiting plate 13 is uniformly and symmetrically provided on the inner wall of the autoclaving chamber 11, a placement plate 14 is slidably provided above the limiting plate 13, the autoclave body 1 also includes a placement groove 15, a placement groove 15 is uniformly provided above the placement plate 14, and through holes are uniformly and symmetrically provided on one side of the placement groove 15 to ensure the flow of steam above and below the placement plate 14 and between each placement groove 15.
[0027] Specifically, the protective mechanism 2 is located above the autoclave body 1. The protective mechanism 2 includes a first fixing plate 22 and a second fixing plate 24. The first fixing plate 22 is fixedly installed at one end of the autoclave 11. The second fixing plate 24 is located on one side of the first fixing plate 22. The top of the first fixing plate 22 is provided with a first hinge seat 23. A drive cylinder 21 is hinged to the top of the first hinge seat 23. The second fixing plate 24 is provided with a second hinge seat 25 at one end. A rotating shaft is rotatably connected to the top of the second hinge seat 25. The connecting plate 26 is hinged to the second hinge seat 25 through the rotating shaft. The output end of the drive cylinder 21 is hinged to one end of the connecting plate 26 via a hinge. The protective mechanism 2 also includes a vessel door 27 and a sealing ring 28. A fixing block is provided at the top of the vessel door 27.

The sealing ring 28 cooperates with the annular groove 12 to effectively seal the autoclave 11. This not only ensures the stability of the pressure inside the autoclave, but also benefits the autoclaving effect of the concrete blocks and avoids unnecessary steam leakage.
[0028] Example 2
[0029] Based on Example 1, in order to further realize the recycling of steam and improve production efficiency, a steam recovery component is installed on one side of the autoclave body.
[0030] The steam recovery assembly 3 includes a dust collector 32, with an air inlet pipe 31 at the top. The other end of the air inlet pipe 31 is sealed to the exhaust pipe 16 of the autoclave body 1. One end of the dust collector 32 is equipped with an air outlet pipe, which is connected to a high-temperature water tank 33 via a pipeline. The high-temperature water tank 33 is located on one side of the dust collector 32, and the other side of the high-temperature water tank 33 is equipped with an air pump 34. Filtered steam enters the high-temperature water tank 33. Inside the high-temperature water tank 33, the heat of the steam is absorbed by the water, raising the water temperature. At the same time, the steam condenses into water. The high-temperature water tank 33 and the air pump 34 are sealed to each other via the air outlet pipe.

[0032] In practical use, concrete blocks are placed in the placement slot 15 of the placement plate 14. The connecting plate 26 is driven by the drive cylinder 21 to open or close the autoclave door 27. The sealing ring 28 cooperates with the annular groove 12 to achieve a seal. During the autoclaving process, steam is used to autoclave the concrete blocks in the autoclaving chamber 11. At the same time, the steam enters the dust removal tank 32 of the steam recovery component 3 through the exhaust pipe 16. After being filtered by the filter cartridge 36, it enters the high-temperature water tank 33 through the exhaust pipe. In the high-temperature water tank 33, it is heated by the heating tube 37 and then sent back to the autoclaving chamber 11 by the air pump 34 through the steam pipe 35, realizing the recovery and utilization of steam and improving energy utilization efficiency.
