Description

Technical Field

[0001] This invention relates to the field of autoclave technology, and in particular to a fully automatic drainage system and method for autoclaves of aerated concrete panels. Background Technology

[0002] After the semi-finished billet of autoclaved aerated concrete is made, it needs to enter the reactor for hydrothermal synthesis reaction to generate sufficient hydration products and achieve the necessary crystallinity so that the product can obtain good performance. When the semi-finished product enters the reactor and high-pressure steam is sent into the reactor, a series of heat exchanges will take place between the steam and the billet, and between the steam and the reactor body, the curing cart and the bottom plate and other equipment. The heat of the steam is transferred to the billet. The higher the heat transfer efficiency, the faster the billet heats up and the shorter the time it takes for the inside and outside of the billet to reach a uniform temperature.

[0003] The heat exchange between steam and the billet begins at the surface of the billet. When high-temperature steam comes into contact with the surface of the billet, it is rapidly cooled and releases heat of vaporization. After the steam condenses, it forms a water film on the surface of the billet and fills the surface pores. At this time, the surface of the billet is heated first, and gradually the temperature and humidity of the outer layer of the billet are higher than those of the inner layer. Under these circumstances, the surface temperature will inevitably be transferred to the lower interior, and the higher-temperature moisture will also penetrate into the inner layer. This transfer and penetration continues until the temperature and humidity inside and outside the billet reach equilibrium. When the temperature of all parts inside and outside the billet is close to equilibrium and the steam in the kettle reaches the required temperature, the heating process ends and the curing enters the constant temperature stage.

[0004] However, in actual use, the inventors discovered the following problems:

[0005] 1. In traditional concrete curing, concrete billets are stacked on formwork, and then the formwork and billets are placed together inside the autoclave for curing. In the part of the billet that is in contact with the formwork and the billets stacked inside, heat is transferred indirectly through the formwork or the outer billets. Since this part of the billet does not have the opportunity to come into direct contact with the steam, and there is no condensate migration from the outside to the inside, the temperature rise of this part of the billet will lag behind the part that is in direct contact with the steam, thus leading to low curing efficiency.

[0006] 2. During the heating stages and the initial stage of constant temperature, heat exchange inside the reactor is frequent, resulting in a large amount of condensate. If the drainage system is not timely, the condensate will accumulate and absorb a large amount of heat from the steam, leading to insufficient heat exchange inside the reactor or excessive pressure changes. This can cause watermarks or steam-curing cracks to appear on the product surface, thus affecting the molding quality of the product. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a fully automatic drainage system for autoclaved aerated concrete (AAC) panels. This system includes an autoclave mechanism, a guiding mechanism, and a clamping mechanism. The guiding mechanism has several sets of clamping mechanisms arranged in an array along its transmission direction. After the multiple sets of clamping mechanisms clamp the concrete billets into the autoclave mechanism, the concrete billets are gradually conveyed forward along the guide rail assembly under the guidance of the guiding mechanism. Since different concrete billets are respectively placed in different clamping mechanisms, the concrete billets are no longer stacked. This allows the high-pressure steam in the autoclave mechanism to fully contact and react with the different concrete billets, thereby reducing the reaction time and improving curing efficiency. This solves the problem of low curing efficiency in traditional autoclaves.

[0008] To address the above technical problems, the following technical solution is adopted: A fully automatic drainage system for autoclaved aerated concrete (AAC) panels, comprising:

[0009] The steam curing kettle mechanism is equipped with a pressure sealing device at its end. The concrete billet is fed into the steam curing kettle mechanism by the pressure sealing device and then transported to the material conveyor belt.

[0010] A guiding mechanism is provided, on which the concrete billet is transferred from the material conveyor belt to the guiding mechanism. Multiple sets of guiding mechanisms are arranged side by side. The guiding mechanism includes a guide rail assembly disposed inside the autoclave mechanism and a drive assembly for driving the guide rail assembly to work. Part of the guide rail assembly is corrugated.

[0011] The clamping mechanism includes a plurality of clamping mechanisms arranged in an array along its transmission direction. The clamping mechanism includes a clamping component, a rotating component disposed on one side of the clamping component, and a fixing component connected to the rotating component and used to fix the concrete blank.

[0012] The clamping mechanism moves the concrete billet on the guide rail assembly while the scraping mechanism scrapes away the condensate on the side of the concrete billet and collects it inside the collection mechanism. The condensate inside the collection mechanism is then evenly sprayed onto the upper surface of the lower concrete billet.

[0013] Preferably, the clamping assembly includes a fixing plate, a first guide member disposed on the fixing plate, and a first transmission member disposed on the first guide member, wherein the first guide member includes a second clamping plate.

[0014] Preferably, the rotating assembly includes a fixed block connected to the first clamping plate or the second clamping plate, a rotating gear rotatably mounted on the fixed block, and a rotating plate connected to the rotating gear. The steam curing vessel mechanism is internally provided with a rotating rack unit that cooperates with the rotating gear.

[0015] Preferably, the fixing component includes a support plate, a second guide member disposed on the support plate, and a second transmission member disposed on the second guide member. The second guide member includes a first sliding block, a second sliding plate, and a retaining plate disposed on the outside of the first sliding block and the second sliding plate.

[0016] Preferably, the scraping mechanism includes a first scraping component disposed between the first clamping plate and the second clamping plate, and a second scraping component disposed on one side of the fixing component for scraping the side of the concrete blank near the fixing component.

[0017] Preferably, the first scraping component includes:

[0018] The control component includes a control block fixedly disposed on the other side of the support plate and a movable column slidably disposed on the first clamping plate or the second clamping plate. The movable column is provided with an arc-shaped limiting plate at a position corresponding to the control block.

[0019] The driving component includes a movable plate fixedly mounted on the movable column, a rotating roller mounted on the movable plate, a transmission belt connected to the rotating roller, and a first driving unit for driving the transmission belt to rotate.

[0020] The scraping component includes a connecting rod disposed on the transmission belt and a telescopic scraper disposed on the connecting rod.

[0021] Preferably, the collection mechanism includes a water tank disposed at the lower end of the scraping mechanism, an upper plate disposed inside the water tank and having a plurality of through holes, an intermediate plate disposed at the lower end of the upper plate and having a plurality of holes corresponding to the through holes, a lower plate disposed at the lower end of the intermediate plate and connected to the upper plate, and a third telescopic unit for driving the intermediate plate to translate.

[0022] Preferably, the guide rail assembly includes a corrugated guide rail member in a corrugated shape and a horizontal guide rail member disposed on the upper end of the corrugated guide rail member and connected to the corrugated guide rail member.

[0023] The drive assembly includes a second drive unit, a reduction unit connected to the second drive unit, a half gear connected to the reduction unit, a first gear connected to the half gear and used to drive the guide rail assembly, and a second gear connected to the half gear and used to drive the blower mechanism.

[0024] Preferably, the lower end of the steam curing autoclave is provided with a blower mechanism at a position corresponding to the lower end of the corrugated guide rail. The blower mechanism includes a blower device and a blower pipe connected to the blower device and disposed toward the end face of the concrete billet.

[0025] This invention also provides a method for draining a fully automatic drainage system for an autoclave of aerated concrete panels, comprising the following steps:

[0026] Step 1, feeding process: the concrete billet continuously enters from the pressure sealing device into the material conveyor belt and is transferred to the clamping mechanism in the guiding mechanism.

[0027] Step 2, autoclaving process: The concrete billet is transferred on the guide mechanism along with the clamping mechanism. At the same time, high-pressure steam is introduced into the autoclave, and a series of heat exchange reactions take place between the high-pressure steam and the concrete billet.

[0028] Step 3: Switching processes. The rotating component in the clamping mechanism will drive the concrete billet to rotate, so that the position of the side and bottom of the concrete billet will change at different positions. In conjunction with the scraping mechanism, the condensate on the side of the concrete billet is scraped off. The collected condensate is evenly sprayed onto the upper surface of the lower concrete billet by the collection mechanism.

[0029] Step four, drainage process: synchronously with step two, the guide mechanism drives the blower mechanism to work. When the blower mechanism is working, it blows the condensate on the lower surface of the concrete billet to the bottom of the steam curing kettle mechanism for collection, and then discharges it in time under the action of the drainage system.

[0030] The beneficial effects of this invention are:

[0031] (1) In this invention, by setting up a steam curing kettle mechanism, a guiding mechanism and a clamping mechanism, the guiding mechanism is arranged with several sets of clamping mechanisms in an array along its transmission direction. After multiple sets of clamping mechanisms clamp the concrete billet into the interior of the steam curing kettle mechanism, the concrete billet will be gradually conveyed forward along the guide rail assembly under the drive of the guiding mechanism. Since different concrete billets are set in different clamping mechanisms, the concrete billets are no longer stacked. In this way, the high-pressure steam in the steam curing kettle mechanism can fully contact and react with different concrete billets, thereby reducing the reaction time and improving the curing efficiency. At the same time, the steam curing kettle mechanism is equipped with a pressure sealing device and a material conveyor belt. During operation, the concrete billet located outside the steam curing kettle mechanism can enter the material conveyor belt through the pressure sealing device and be transferred to the clamping mechanism in the guiding mechanism without stopping the steam curing kettle mechanism. This realizes the continuous processing of the concrete billet, further improves the curing efficiency and reduces the production cost of the enterprise.

[0032] (2) In this invention, a scraping mechanism is set up in conjunction with a clamping mechanism and a collection mechanism. The scraping mechanism includes a first scraping component and a second scraping component. When working, when the clamping mechanism moves the concrete billet on the guide mechanism, the rotating component in the clamping mechanism will drive the concrete billet to rotate, so that the position of the side and bottom of the concrete billet will change at different positions. When there is a lot of condensate on the side of the concrete billet, the first scraping component and the second scraping component work simultaneously or separately to scrape off the condensate on the side of the concrete billet and transport the condensate to the inside of the collection mechanism. After the condensate enters the inside of the collection mechanism, it will be evenly sprayed to the upper surface of the lower concrete billet by the collection mechanism. The condensate will continue to penetrate downward along the upper surface of the concrete billet, thereby realizing the secondary use of the condensate and further improving the curing efficiency of the concrete billet. It also avoids the product molding quality being affected by the long-term adhesion of the condensate to the surface of the concrete billet.

[0033] (3) In this invention, by setting the clamping mechanism including a clamping component, a rotating component and a fixing component, when the clamping mechanism moves on the guide mechanism, the first clamping plate and the second clamping plate set on the clamping component can change their relative positions, thereby changing the relative positions of the fixing components on the first clamping plate and the second clamping plate, so that the fixing component can clamp concrete blanks of different lengths. The first sliding plate and the second sliding plate on the fixing component, together with the clamping plate, can clamp concrete blanks of different widths. In this way, the clamping mechanism can realize the clamping work of concrete blanks of various specifications, which is highly applicable and easy to use.

[0034] (4) In this invention, by setting a guide mechanism and a blower mechanism, the drive component in the guide mechanism can drive the guide rail assembly and the blower mechanism to work alternately when working. When the guide rail assembly works, it can drive the clamping mechanism to move gradually on the guide rail assembly. When the blower mechanism works, it can blow the condensate on the lower surface of the concrete billet at the bottom to the bottom of the steam curing kettle mechanism for collection, and discharge it in time under the drive of the drainage system. The structure is simple and easy to use.

[0035] In summary, this equipment has the advantages of high curing efficiency and good product molding quality, and is especially suitable for the field of steam curing kettle technology. Attached Figure Description

[0056] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0057] Example 1

[0058] like Figures 1-4 As shown, an automatic drainage system for an autoclave of aerated concrete panels includes:

[0059] The steam curing kettle mechanism 1 is equipped with a pressure sealing device at its end. The concrete billet is fed into the steam curing kettle mechanism 1 by the pressure sealing device and then transported to the material conveyor belt.

[0060] The concrete billet 100 is transferred from the material conveyor belt to the guide mechanism 2. Multiple guide mechanisms 2 are arranged side by side. The guide mechanism 2 includes a guide rail assembly 21 disposed inside the steam curing kettle mechanism 1 and a drive assembly 22 for driving the guide rail assembly 21 to work. Part of the guide rail assembly 21 is corrugated.

[0061] The clamping mechanism 3 is arranged in an array along the transmission direction of the guide mechanism 2. The clamping mechanism 3 includes a clamping component 31, a rotating component 32 disposed on one side of the clamping component 31, and a fixing component 33 connected to the rotating component 32 and used to fix the concrete blank 100.

[0062] While the clamping mechanism 3 moves the concrete blank 100 on the guide rail assembly 21, it works in conjunction with the scraping mechanism 4 to scrape off the condensate on the side of the concrete blank 100 and collect it inside the collection mechanism 5. The condensate inside the collection mechanism 5 is then evenly sprayed onto the upper surface of the lower concrete blank 100.

[0063] In this embodiment, by setting up a steam curing kettle mechanism 1, a guiding mechanism 2, and a clamping mechanism 3, the guiding mechanism 2 is arranged with several sets of clamping mechanisms 3 in an array along its transmission direction. After the multiple sets of clamping mechanisms 3 clamp the concrete blanks 100 into the interior of the steam curing kettle mechanism 1, the concrete blanks 100 will be gradually conveyed forward along the guide rail assembly 21 under the drive of the guiding mechanism 2. Since different concrete blanks 100 are respectively set in different clamping mechanisms 3, the concrete blanks 100 are no longer stacked. In this way, the high-pressure steam in the steam curing kettle mechanism 1 can fully contact and react with different concrete blanks 100, thereby reducing the reaction time and improving the curing efficiency.

[0064] It should be noted that the steam curing kettle mechanism 1 is equipped with a pressure sealing device and a material conveyor belt (the pressure sealing device is located at the inlet and outlet of the steam curing kettle mechanism 1). Specifically, the pressure sealing device can be a rotary drum-type inlet and outlet sealing device used in a high-efficiency continuous vacuum microwave dryer disclosed in CN204115430U. This allows the concrete billet 100 to continuously enter the material conveyor belt from the pressure sealing device and be transferred to the clamping mechanism 3 in the guide mechanism 2 without changing the steam pressure and temperature in the steam curing kettle mechanism 1. (This transfer process can be carried out by setting a transfer robot or other mechanical structure inside the steam curing kettle mechanism 1, which are all existing technologies and will not be described in detail here.) This enables the continuous processing of the concrete billet 100.

[0065] Furthermore, such as Figures 5-7 As shown, the clamping assembly 31 includes:

[0066] A fixing plate 311 is fixedly mounted on the guide rail assembly 21 and a first telescopic unit 3111 is provided on the fixing plate 311.

[0067] The first guide member 312 includes a first clamping plate 3121 connected to the first telescopic unit 3111, a first slider 3122 disposed on the first clamping plate 3121, a first slide rail 3123 cooperating with the first slider 3122 and disposed on the fixed plate 311, and a second clamping plate 3125 disposed on the first slide rail 3123 away from the first clamping plate 3121 and disposed on the first slide rail 3123 via a second slider 3124;

[0068] The first transmission component 313 includes a first rack 3131 connected to the first clamping plate 3121, a second rack 3132 connected to the second clamping plate 3125, and transmission gears 3133 that respectively cooperate with the first rack 3131 and the second rack 3132.

[0069] The rotating assembly 32 includes a fixed block 321 connected to the first clamping plate 3121 or the second clamping plate 3125, a rotating gear 322 rotatably mounted on the fixed block 321, and a rotating plate 323 connected to the rotating gear 322. The steaming kettle mechanism 1 is provided with a rotating rack unit 11 that cooperates with the rotating gear 322.

[0070] The fixing component 33 includes:

[0071] Support plate 331, the support plate 331 is connected to the rotating plate 323 and the support plate 331 is provided with a second telescopic unit 3311;

[0072] The second guide member 332, the first transmission member 313 includes a first sliding plate 3321 connected to the second telescopic unit 3311, a first sliding block 3323 connected to the first sliding plate 3321 and disposed on the second slide rail 3322, and a second sliding plate 3325 disposed on the second slide rail 3322 away from the first sliding plate 3321 and disposed on the second slide rail 3322 via the second sliding block 3324. The outer sides of the first sliding plate 3321 and the second sliding plate 3325 are both connected to a clamping plate 3326 for supporting the concrete blank 100.

[0073] The second transmission component 333 includes a first connecting rod 3331 hinged to the first sliding plate 3321, a second connecting rod 3332 hinged to the second sliding plate 3325, and a third connecting rod 3333 hinged to the first connecting rod 3331 and the second connecting rod 3332 and rotatably mounted on the support plate 331.

[0074] In this embodiment, by setting the clamping mechanism 3 including a clamping component 31, a rotating component 32 and a fixing component 33, when the clamping mechanism 3 moves on the guide mechanism 2, the relative positions of the first clamping plate 3121 and the second clamping plate 3125 on the clamping component 31 can be changed, thereby changing the relative position of the fixing component 33 on the first clamping plate 3121 and the second clamping plate 3125. This allows the fixing component 33 to clamp concrete blanks 100 of different lengths. The first sliding plate 3321 and the second sliding plate 3325 on the fixing component 33, together with the clamping plate 3326, can clamp concrete blanks 100 of different widths. In this way, the clamping mechanism 3 can realize the clamping work of concrete blanks 100 of various specifications, which is highly applicable and easy to use.

[0075] In detail, during operation, the fixing plate 311 is fixedly mounted on the guide rail assembly 21. When it is necessary to clamp the concrete blank 100, the guide rail assembly 21 drives the clamping mechanism 3 to move to the position corresponding to the concrete blank 100. Then, the first telescopic unit 3111 works and drives the first clamping plate 3121 to move toward the second clamping plate 3125. At the same time, the first clamping plate 3121 will also drive the first rack 3131 to move, which in turn drives the transmission gear 3133 to rotate. After the transmission gear 3133 rotates, it will drive the second rack 3132 to move in the opposite direction to the first rack 3131. At this time, the second clamping plate 3125 will move toward the direction of the first clamping plate 3121 in sync, thereby realizing the adjustment of the relative positions of the two sets of fixing components 33 on the first clamping plate 3121 and the second clamping plate 3125.

[0076] As the first clamping plate 3121 and the second clamping plate 3125 approach each other, the support plates 331 on the two sets of fixing components 33 also approach each other synchronously. At this time, the second telescopic unit 3311 works and drives the first sliding plate 3321 to slide on the second slide rail 3322. While sliding, the first sliding plate 3321 also drives the first connecting rod 3331 to rotate. After the first connecting rod 3331 rotates, it drives the third connecting rod 3333 to rotate on the support plate 331 and drives the second connecting rod 3332 to rotate, thereby driving the second sliding plate 3325 to slide on the second slide rail 3322. The clamping plates 3326 set on the first sliding plate 3321 and the second sliding plate 3325 approach each other. After the four sets of clamping plates 3326 complete the clamping work on the concrete blank 100, the clamping mechanism 3 completes the clamping of the concrete blank 100. Then, the clamping mechanism 3 can drive the concrete blank 100 to carry out subsequent processing work.

[0077] When the clamping mechanism 3 moves the concrete blank 100 on the guide mechanism 2, the rotating gear 322 in the rotating assembly 32 will contact the rotating rack unit 11 set inside the steam curing kettle mechanism 1 and rotate, thereby driving the rotating plate 323 to rotate. After the rotating plate 323 rotates, it will drive the fixing assembly 33 and the concrete blank 100 to rotate simultaneously. After the rotating gear 322 completes one contact engagement with the rotating rack unit 11, the rotating gear 322 will drive the concrete blank 100 to rotate 90°.

[0078] It should be noted that the concrete blank 100 used in this embodiment preferably has a square side near the fixing component 33. In this way, even if the concrete blank 100 rotates 90°, the distance between the scraping mechanism 4 and the sides of different concrete blanks 100 will always remain the same, and it will not affect the subsequent scraping work of the scraping mechanism 4 on the sides of different concrete blanks 100.

[0079] Furthermore, such as Figures 8-12 As shown, the scraping mechanism 4 includes a first scraping component 41 disposed between the first clamping plate 3121 and the second clamping plate 3125, and a second scraping component 42 disposed on one side of the fixing component 33 for scraping the side of the concrete blank 100 near the fixing component 33.

[0080] The first scraping component 41 includes:

[0081] The control component 411 includes a control block 4111 fixedly disposed on the other side of the support plate 331 and a movable column 4112 slidably disposed on the first clamping plate 3121 or the second clamping plate 3125. The movable column 4112 is provided with an arc-shaped limiting plate 4113 at a position corresponding to the control block 4111.

[0082] The driving component 412 includes a movable plate 4121 fixedly mounted on the movable column 4112, a rotating roller 4122 mounted on the movable plate 4121, a transmission belt 4123 connected to the rotating roller 4122, and a first driving unit 4124 for driving the transmission belt 4123 to rotate.

[0083] The scraping component 413 includes a connecting rod 4131 disposed on the transmission belt 4123 and a telescopic scraper 4132 disposed on the connecting rod 4131.

[0084] In this embodiment, a scraping mechanism 4 is provided in conjunction with a clamping mechanism 3. The scraping mechanism 4 includes a first scraping component 41 and a second scraping component 42. During operation, when the clamping mechanism 3 moves the concrete blank 100 on the guide mechanism 2, the rotating component 32 in the clamping mechanism 3 will drive the concrete blank 100 to rotate, so that the position of the side and bottom of the concrete blank 100 will change at different positions. When there is a lot of condensate on the side of the concrete blank 100, the first scraping component 41 and the second scraping component 42 work simultaneously or individually to scrape off the condensate on the side of the concrete blank 100, preventing the condensate from adhering to the surface of the concrete blank 100 for a long time and thus affecting the product molding quality.

[0085] In detail, while the clamping assembly 31 and the fixing assembly 33 are working and clamping the concrete blank 100, the first scraping assembly 41 moves synchronously with the movement of the first clamping plate 3121, the second clamping plate 3125, the first sliding plate 3321, and the second sliding plate 3325. On the one hand, the moving column 4112 is slidably set with the first clamping plate 3121 or the second clamping plate 3125. Therefore, the first scraping assembly 41 can move with the first clamping plate 3121 or the second clamping plate 3125. At this time, the telescopic scraper 4132 in the scraper 413 will be squeezed and become wavy, but it will not affect the scraping effect on the condensate. On the other hand, when the first sliding plate... When the first sliding plate 3321 or the second sliding plate 3325 moves, the control block 4111 will drive the arc-shaped limiting plate 4113 to slide along with the first sliding plate 3321 or the second sliding plate 3325 (but when the control block 4111 rotates with the support plate 331, the control block 4111 will disengage from the arc-shaped limiting plate 4113 and will not drive the arc-shaped limiting plate 4113 to rotate), thereby driving the first scraping component 41 to move. In this way, the relative position between the scraping component 413 and the clamping plate 3326 remains consistent. While the clamping mechanism 3 completes the clamping work on the concrete blank 100, the clamping mechanism 3 also simultaneously drives the first scraping component 41 and the second scraping component 42 to move to the appropriate position.

[0086] After moving to the appropriate position, and when it is necessary to scrape the concrete blank 100, the first drive unit 4124 works and drives the transmission belt 4123 to rotate through the rotating roller 4122. After the transmission belt 4123 rotates, it will drive the connecting rod 4131 and the telescopic scraper 4132 to move. Then the telescopic scraper 4132 will approach the concrete blank 100 and scrape the condensate on the side of the concrete blank 100 from top to bottom. After the scraping work is completed, the scraper 413 will move with the transmission belt 4123 to a position away from the concrete blank 100. In this way, when the concrete blank 100 rotates, it will not interfere with the scraper 413.

[0087] It should be noted that the first scraping component 41 and the second scraping component 42 have the same structure, the difference being their positions and the parts to be processed. Therefore, the specific structure of the second scraping component 42 will not be described in detail.

[0088] When the fixing component 33 drives the concrete blank 100 to rotate, the first scraping component 41 will not rotate with the fixing component 33, while the second scraping component 42 will rotate with the fixing component 33. Therefore, the first scraping component 41 can scrape different sides of the concrete blank 100. Since the second scraping component 42 will scrape horizontally after rotating 90° with the fixing component 33, the second scraping component 42 can be set to work after the fixing component 33 rotates 180° with the concrete blank 100. This ensures that the condensate scraped off each time will fall down.

[0089] The telescopic scraper 4132 can be made of a highly hydrophobic material. Preferably, the telescopic scraper 4132 is a combination of an elastic rubber plate and a highly hydrophobic fabric (the fabric is placed on the outside of the elastic rubber plate and the fabric is also elastic). When the telescopic scraper 4132 extends or retracts, the elastic rubber plate can drive the fabric to extend or retract. During the scraping work, one end of the fabric is placed in close contact with the concrete blank 100 and scrapes it.

[0090] Furthermore, such as Figures 13-15 As shown, the collection mechanism 5 includes a water tank 51 disposed at the lower end of the scraping mechanism 4, an upper plate 52 disposed inside the water tank 51 and having a plurality of through holes 521, an intermediate plate 53 disposed at the lower end of the upper plate 52 and having a plurality of holes corresponding to the through holes 521, a lower plate 54 disposed at the lower end of the intermediate plate 53 and connected to the upper plate 52, and a third telescopic unit 55 for driving the intermediate plate 53 to translate.

[0091] In this embodiment, by setting up a scraping mechanism 4 in conjunction with a collection mechanism 5, the condensate on the side of the concrete blank 100 is scraped off and transported to the inside of the collection mechanism 5. After entering the inside of the collection mechanism 5, the condensate is evenly sprayed onto the upper surface of the lower concrete blank 100. This part of the condensate will continue to seep downwards along the upper surface of the concrete blank 100, thereby realizing the secondary utilization of this part of the condensate and further improving the curing efficiency of the concrete blank 100.

[0092] In detail, the water storage tank 51 is annular, so that the condensate scraped off from the top of the concrete blank 100 will fall into the interior of the water storage tank 51. The condensate that falls into the water storage tank 51 will flow out from the interior of the water storage tank 51 and flow to the upper surface of the upper plate 52, and then fill the interior of the through hole 521. After all the condensate inside the water storage tank 51 has flowed onto the upper plate 52, the third telescopic unit 55 is controlled to work and drive the middle plate 53 to move, so that the through holes 521 opened on the upper plate 52, the middle plate 53 and the lower plate 54 are all aligned. At this time, the condensate will flow down from the lower plate 54 along the through hole 521 and flow to the upper surface of the lower concrete blank 100.

[0093] It should be noted that, since the guide rail assembly 21 is equipped with a corrugated guide rail, when the clamping mechanism 3 moves the concrete billet 100 from bottom to top, in order to ensure that the collecting mechanism 5 can still work normally, water storage tanks 51 need to be provided on the outer side of the upper plate 52 and the lower plate 54. In this way, when the concrete billet 100 moves from bottom to top, the lower plate 54 is located at the upper end of the upper plate 52, and the falling condensate will fall into the water storage tank 51 near the lower plate 54. At this time, the condensate inside the water storage tank 51 will flow to the upper end of the lower plate 54, and the water storage tank 51 can be connected to the fixing plate 311.

[0094] Example 2

[0095] like Figures 16-18 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0096] Furthermore, the guide rail assembly 21 includes a corrugated guide rail 211 in a corrugated shape and a horizontal guide rail 212 disposed on the upper end of the corrugated guide rail 211 and connected to the corrugated guide rail 211.

[0097] The drive assembly 22 includes a second drive unit 221, a reduction unit 222 connected to the second drive unit 221, a half gear 223 connected to the reduction unit 222, a first gear 224 connected to the half gear 223 and used to drive the guide rail assembly 21, and a second gear 225 connected to the half gear 223 and used to drive the blower mechanism 6.

[0098] At the lower end of the steam curing kettle mechanism 1, a blower mechanism 6 is provided at the position corresponding to the lower end of the corrugated guide rail 211. The blower mechanism 6 includes a blower device 61 and a blower pipe 62 connected to the blower device 61 and arranged towards the end face of the concrete blank 100. The blower device 61 can be a rotating fan, and the blower pipe 62 is a pipe body arranged in a conical shape outside the rotating fan.

[0099] In this embodiment, by setting a guide mechanism 2 and a blower mechanism 6, the drive component 22 in the guide mechanism 2 can drive the guide rail component 21 and the blower mechanism 6 to work alternately when working. When the guide rail component 21 works, it can drive the clamping mechanism 3 to move gradually on the guide rail component 21. When the blower mechanism 6 works, it can blow the condensate on the lower surface of the concrete blank 100 at the bottom to the bottom of the steam curing kettle mechanism 1 for collection, and discharge it in time under the drive of the drainage system. The structure is simple and easy to use.

[0100] In detail, the guide rail assembly 21 is a sprocket and chain drive unit. When the second drive unit 221 is working, it drives the half gear 223 to rotate through the reduction unit 222 and intermittently drives the first gear 224 and the second gear 225 to rotate alternately. When the first gear 224 rotates, the first gear 224 will drive the guide rail assembly 21 to work and thus drive the clamping mechanism 3 to move. When the second gear 225 rotates, the second gear 225 will drive the rotating fan to rotate (the second gear 225 can be connected to the blower 61 through a belt). The air generated after the rotating fan rotates will flow in the blower pipe 62 and blow towards the side of the concrete blank 100.

[0101] It should be noted that, in order to ensure that the blower 61 blows down as much of the condensate on the side of the concrete blank 100 as possible, the concrete blank 100 at the bottom can be set to rotate only 45° when it is in that position, and the blower 61 is set on both sides of the concrete blank 100. In this way, after the blower 61 works, it will blow the condensate along the downward inclined surface, which is conducive to the condensate falling. For this reason, the rotating rack unit 11 at this position is only half the length of the upper rotating rack unit 11.

[0102] After the condensate at the bottom falls, it enters the interior of the drainage pipe, and the condensate in the reactor is drained in stages to pipes with different pressures. Specifically:

[0103] When the pressure inside the reactor is 0~1 bar, the long delivery pipeline cannot push the condensate to be delivered due to the low pressure. Therefore, the small-diameter drain pipe is opened for auxiliary drainage.

[0104] When the pressure inside the reactor is 1~3 bar, the condensate is sent to the static shutdown kiln pipeline for heating and then sent to the casting water tank;

[0105] When the pressure inside the reactor is 3~13 bar, the condensate inside the reactor is transported to the gas-liquid separator through the mechanical drain valve and the liquid level control valve. The separated steam is used for heating in front of the reactor, and the hot water is transported to the pre-curing kiln for heating and then to the casting water tank.

[0106] The use of this system has greatly reduced the consumption of high-pressure steam (from 140 kg / m³ to 100 kg / m³) and enabled the reactor to precisely remove condensate, resulting in stable reaction inside the reactor and improved product qualification rate.

[0107] Example 3

[0108] like Figure 19 As shown, a method for draining water from a fully automatic drainage system for an autoclave of aerated concrete panels includes the following steps:

[0109] Step 1, feeding process: the concrete billet 100 continuously enters the material conveyor belt from the pressure sealing device and is transferred to the clamping mechanism 3 in the guide mechanism 2.

[0110] Step 2, autoclaving process: the concrete billet 100 is transferred on the guide mechanism 2 along with the clamping mechanism 3. At the same time, high-pressure steam is introduced into the autoclave, and a series of heat exchange reactions take place between the high-pressure steam and the concrete billet 100.

[0111] Step 3, switch processes. The rotating component 32 in the clamping mechanism 3 will drive the concrete blank 100 to rotate, so that the position of the side and bottom of the concrete blank 100 will change at different positions. In conjunction with the scraping mechanism 4, the condensate on the side of the concrete blank 100 is scraped off. The collected condensate is evenly sprayed onto the upper surface of the lower concrete blank 100 by the collecting mechanism 5.

[0112] Step four, drainage process. Simultaneously with step two, the guide mechanism 2 drives the blower mechanism 6 to work. When the blower mechanism 6 is working, it blows the condensate on the lower surface of the concrete blank 100 at the bottom to the bottom of the steam curing kettle mechanism 1 for collection, and then discharges it in time under the action of the drainage system.
