Description

Technical Field

[0001] This invention relates to the field of autoclaving technology for building materials, and in particular to an autoclaving device for the production of energy-saving building materials. Background Technology

[0002] In the production of energy-saving building materials, autoclaving equipment is one of the key pieces of equipment. Traditional autoclaving equipment is mainly used to cure building materials under high temperature and high pressure to improve their strength and durability. With the rapid development of the construction industry, the requirements for energy-saving and environmentally friendly building materials are becoming increasingly stringent.

[0003] In existing technologies, autoclaving devices are commonly used to autoclave energy-saving and environmentally friendly building materials. However, existing autoclaving devices often simply place the building materials directly into the autoclaving device and perform a simple autoclaving operation through a steam generator.

[0004] However, in this ordinary autoclaving method, a large amount of steam condenses into water during the autoclaving process, causing the energy-saving aerated bricks at the bottom to be soaked in condensate water, thus affecting the autoclaving quality of the building materials. Furthermore, the presence of liquefied water on the inner wall also affects the autoclaving quality. Summary of the Invention

[0005] (a) Purpose of the invention

[0006] To address the technical problems existing in the background art, this invention proposes an autoclaving device for energy-saving building material production. This device can achieve hot steam circulation, thereby effectively preventing the hot steam from liquefying and accumulating at the bottom of the building material if it remains in a fixed area. This effectively improves the autoclaving effect of the building material. Furthermore, during the hot steam circulation process, the device can also effectively drive the scraper ring to move up and down reciprocally, so as to re-vaporize the liquefied hot steam on the inner wall of the autoclave. This further prevents the liquefied water vapor from soaking the bottom of the building material and affecting its performance. In addition, the device can also drive the building material to move through the support mechanism while the scraper ring moves up and down reciprocally. This effectively reduces the contact area between the building material and the device, and makes the autoclaving effect of each area of ​​the building material more uniform, thereby further improving the quality of the autoclaving of the building material.

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention.

[0032] In the description of the invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] like Figure 1-8 As shown, the present invention proposes an autoclaving device for energy-saving building material production, comprising an autoclave 1, a bottom plate 2, and a top plate 3. The autoclave 1 has a first opening and a second opening at its upper and lower ends, respectively. The bottom plate 2 and top plate 3 are connected to the autoclave 1 and respectively seal the second opening and the first opening. The bottom end of the top plate 3 has a first groove, and the upper end of the bottom plate 2 has a second groove. The bottom end of the second groove has a water inlet with a sealing valve. A heating device is installed in the second groove. A first mounting plate 4 for sealing the first groove is provided. The upper end of the inner wall of the autoclave 1 has a first through hole. The inner walls of the first and second grooves each have a second through hole and a third through hole communicating with the first through hole. The first mounting plate 4 has a fourth through hole for guiding air, and a negative pressure fan 5 is installed in the fourth through hole. The top plate 3 has a device for driving the negative pressure fan 5 to rotate. A rotating mechanism is provided. A scraper ring 7 is slidably installed inside the autoclave 1. A heating mechanism is provided on the scraper ring 7. The scraper ring 7 is slidably installed against the inner wall of the autoclave 1. The scraper ring 7 is connected to the rotating mechanism through a transmission mechanism. The rotating mechanism drives the scraper ring 7 to move up and down reciprocally so as to heat the inner wall of the autoclave 1 through the heating mechanism. A support mechanism is movably installed in the second groove. A second mounting plate 22 is provided on the second groove. The second mounting plate 22 has a third opening for the support mechanism to pass through. The support mechanism is slidably installed in the third opening and seals the third opening. An air outlet is provided on the second mounting plate 22. The autoclave 1 has a feeding port. A sealing plate 21 is rotatably installed at the feeding port. The sealing plate 21 rotates to fit against the inner wall of the first opening to seal the feeding port. The sealing plate 21 is magnetically attracted to the autoclave 1.

[0034] Specifically, the first mounting plate offers two options: a metal plate (stainless steel, 10mm thick) and a plastic plate (polycarbonate, 10mm thick). The metal plate has good high-temperature resistance and is suitable for long-term high-load operation; the plastic plate has better insulation and is lightweight, making it suitable for short-term low-load use.

[0035] In this invention, when the device is needed, the building materials to be steamed are placed in the autoclave 1 and rested on the second mounting plate 22. Water is introduced through the water inlet, and the heating device in the second groove heats the materials and generates steam for the autoclaving operation. During the autoclaving process, hot steam is generated. The rotating mechanism drives the negative pressure fan 5 to rotate, thereby generating negative pressure. During the autoclaving of the building materials, the hot steam is drawn into the first groove. The steam enters the second groove through the first, second, and third through holes, and then re-enters the autoclave 1 through the air outlet, realizing steam circulation. This effectively prevents the hot steam from being continuously... Located inside the autoclave 1, the water vapor liquefies within the autoclave, thus affecting the building materials. The device, through a rotating mechanism driving the negative pressure fan 5, drives the scraper ring 7 to move vertically via a transmission mechanism. This vertical movement of the scraper ring 7 drives the heating mechanism to move vertically as well, heating the liquefied water vapor adhering to the inner wall of the autoclave 1, causing it to re-vaporize. This effectively prevents the liquefied water adhering to the autoclave 1 from falling back onto the second mounting plate 22 and affecting the building materials, thereby improving the autoclaving effect. Furthermore, the movement of the scraper ring 7, via a connecting mechanism, also... The moving support mechanism moves vertically, effectively driving the building material upwards. This reduces the contact area between the building material and the second mounting plate 22, improving the steam pressure effect on the bottom of the building material. Furthermore, the vertical movement of the building material allows for adjustment of its position within the steam pressure tank 1, ensuring different areas of the building material are located in different steam pressure zones. This results in more uniform steam pressure and improved steam pressure performance. The device also enables hot steam circulation, effectively preventing liquefaction of the hot steam within a fixed area. The material accumulates at the bottom of the building materials, effectively improving the autoclaving effect. Furthermore, during the hot steam circulation process, the device effectively drives the scraper ring 7 to move up and down, re-vaporizing the liquefied hot steam on the inner wall of the autoclave 1. This further prevents liquefied water vapor from soaking the bottom of the building materials. Simultaneously, the device drives the building materials to move via a support mechanism while the scraper ring 7 moves up and down. This effectively reduces the contact area between the building materials and the device, ensuring a more uniform autoclaving effect in each area of ​​the building materials, thus further improving the quality of the autoclaving process.

[0036] In an optional embodiment, the support mechanism includes a top block 8 and a connecting block 9. The two top blocks 8 are slidably disposed within the third opening, with the bottom end of the top block 8 fitting against the inner wall of the second groove. The two top blocks 8 are connected by the connecting block 9, which is slidably disposed against the inner wall of the third opening. The connecting block 9 is connected to the scraper ring 7 via a connecting assembly. The top blocks 8 can effectively support the building material, and the top blocks 8 are connected to the scraper ring 7 via the connecting block 9 and the connecting assembly. Thus, the top blocks 8 can be moved during the movement of the scraper ring 7. Furthermore, the scraper ring 7 and the top blocks 8 drive each other in this device, allowing the steam generated during the vaporization of liquefied water on the inner wall of the autoclave 1 by the scraper ring 7 and the heating mechanism to autoclave the bottom end of the building material as much as possible. This effectively compensates for the poor autoclaving effect caused by the bottom end of the building material being supported by the second mounting plate 22, thereby effectively improving the autoclaving effect of the device.

[0037] In an optional embodiment, the connecting assembly includes a transmission block 10, a connecting rod 15, and a mounting cylinder 16. The transmission block 10 is slidably disposed within the third opening and connected to the connecting block 9. The upper end of the transmission block 10 is connected to the mounting cylinder 16, which has an upper opening. One end of the connecting rod 15 is connected to the bottom end of the scraper ring 7, and the other end of the connecting rod 15 extends into the mounting cylinder 16 and is slidably connected to it. The mounting cylinder 16 is provided with a limiting unit to prevent the connecting rod 15 from sliding out. The transmission block 10 is connected to two connecting blocks 9 and is... When the scraper ring 7 moves upward, the connecting rod 15 and the mounting cylinder 16 first drive the connecting rod 15 to move within the mounting cylinder 16. After the connecting rod 15 moves to its limit position within the mounting cylinder 16, it then drives the mounting cylinder 16 to move. This effectively drives the movement of the transmission block 10, the connecting block 9, and the top block 8. Furthermore, because the connecting rod 15 slides within the mounting cylinder 16, when the scraper ring 7 moves downward, the connecting rod 15 can also move within the mounting cylinder 16, thus preventing the top block 8 from directly obstructing the movement of the scraper ring 7 after it contacts the inner wall of the second groove.

[0038] In an optional embodiment, the limiting unit includes a limiting block 23. A groove is provided on the inner wall of the mounting cylinder 16. The limiting block 23 is slidably disposed in the groove and connected to the connecting rod 15. By allowing the limiting block 23 to slide in the groove and be connected to the connecting rod 15, the connecting rod 15 can be effectively prevented from moving out of the mounting cylinder 16 during the movement.

[0039] In an optional embodiment, the rotating mechanism includes a drive shaft 11. The upper end of the top plate 3 is provided with a fifth through hole that communicates with the first groove. The drive shaft 11 is rotatably disposed in the fifth through hole and slides against its inner wall. The drive shaft 11 is coaxially connected to the negative pressure fan blade 5. The top plate 3 is provided with a drive assembly for driving the drive shaft 11. The drive shaft 11 is connected to the transmission mechanism. The drive assembly drives the drive shaft 11 to rotate. The rotation of the drive shaft 11 can effectively drive the negative pressure fan blade 5 to rotate, generating negative pressure to achieve steam circulation. In addition, the drive shaft 11 can also drive the transmission mechanism to run during the transmission process, thereby driving the scraper ring 7 to move up and down reciprocally through the transmission mechanism.

[0040] In an optional embodiment, the transmission mechanism includes a cylindrical cam 12, a transmission head 13, and a slider 14. The cylindrical cam 12 is rotatably mounted on the upper end of the top plate 3 and is connected to the transmission shaft 11. The slider 14 is located on the upper end of the top plate 3. The slider 14 passes through the top plate 3 and the first mounting plate 4 in sequence and is connected to the scraper ring 7. The slider 14 is slidably connected to the top plate 3 and the first mounting plate 4. The slider 14 is provided with a transmission head 13, which is configured to cooperate with the cylindrical cam 12. During the process of the drive mechanism driving the negative pressure fan blade 5 to rotate, the transmission cylindrical cam 12 is driven to rotate. During the rotation of the cylindrical cam 12, the transmission head 13 that cooperates with it will move up and down, thereby driving the slider 14 connected with it to move up and down, thereby driving the scraper ring 7 to move up and down.

[0041] In an optional embodiment, the drive assembly includes a motor 18 and a rotating shaft 19. The motor 18 is connected to the upper end of the top plate 3, and the rotating shaft 19 is coaxially connected to the output shaft of the motor 18 and is connected to the transmission shaft 11 for transmission. The motor 18 can effectively drive the rotating shaft 19 to rotate, and the rotation of the rotating shaft 19 drives the transmission shaft 11 to rotate.

[0042] In an optional embodiment, a first pulley is provided on the rotating shaft 19, and a second pulley is provided on the transmission shaft 11. The first pulley and the second pulley are connected by a belt drive.

[0043] In an optional embodiment, a first sprocket is provided on the drive shaft 11, and a second sprocket is coaxially provided on the cylindrical cam 12. The first sprocket and the second sprocket are connected by a chain drive.

[0044] In an optional embodiment, the heating mechanism includes a heater 20, with the upper end of a scraper ring 7 connected to the heater 20. There is a gap between the heater 20 and the inner wall of the autoclave 1. The heater 20 moves up and down by the upward movement of the scraper ring 7, which can effectively vaporize the liquefied hot steam on the inner wall of the autoclave 1. The gap between the heater 20 and the inner wall of the autoclave 1 can effectively prevent the heater 20 from directly contacting the liquefied water, thereby improving the stability of the heater 20 in use.

[0045] Specifically, the scraper ring consists of two main parts: the main frame (high-strength alloy steel, cross-sectional dimensions 100mm x 10mm) and the heating mechanism. The main frame is made of high-strength alloy steel with a rust-proof surface treatment, exhibiting good wear resistance and fatigue strength. The heating mechanism can use either an electric heating wire (resistance value 10Ω / m) or an infrared heating lamp (power 1kW / m). The electric heating wire is suitable for applications requiring rapid heating; the model is JL-100W nickel-chromium alloy resistance wire. The infrared heating lamp is more suitable for long-term constant-temperature heating. The contact surface between the scraper ring and the inner wall of the autoclave is covered with a flexible material, such as silicone (2mm thick) or rubber (2mm thick), ensuring a tight fit while preventing scratches on the inner wall.

[0046] In an optional embodiment, the inner wall of the scraper ring 7 is provided with an annular groove, and the heater 20 is located in the annular groove and connected to the inner wall of the annular groove. This can further prevent the heater 20 from directly contacting the water, and conduct heat to the liquefied water on the inner wall of the autoclave 1 through a better heat conduction medium, which can further improve the effect of the heater 20 in re-vaporizing the liquefied water.

[0047] In an optional embodiment, the second mounting plate 22 is provided with a support block 17, which is staggered with the top block 8. This effectively reduces the contact area between the building material and the device when the building material is steam-pressed under normal conditions. Furthermore, when the top block 8 moves the building material upward, the contact position between the building material and the support block 17 can be emptied, thereby allowing for a more comprehensive steam-pressing operation and further improving the steam-pressing effect of the device.

[0048] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the invention should be included within the protection scope of the invention. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
