Description

Technical Field

[0001] The utility model relates to the technical field of concrete production accessories, and particularly relates to an autoclaving device for concrete production. Background Technique

[0002] An autoclave is a special device used for autoclave curing of concrete or other materials. It is usually a cylindrical or cuboid-shaped sealed container made of high-temperature and high-pressure resistant steel, equipped with components such as a sealed door, safety valve, pressure gauge, and thermometer. Its working principle is to cure materials through high-temperature and high-pressure steam, accelerate the hydration reaction, and promote strength development. The main parameters of the autoclave include temperature (usually between 170 - 200 °C), pressure (generally 0.8 - 1.2 MPa), and capacity (ranging from several cubic meters to several hundred cubic meters depending on production requirements). It is widely used in the production of autoclaved aerated concrete, the manufacture of precast concrete components, the production of brick and tile products, and the curing of certain building materials. The advantages of the autoclave are that it shortens the curing time, improves production efficiency, improves the quality and performance of products, and saves factory space. However, when using an autoclave, attention should be paid to safe operation, regular maintenance and inspection, and reasonable control of the heating and cooling rates. Modern autoclaves tend to be automated and equipped with precise control systems to improve production consistency and reliability. Although the autoclaving process consumes a relatively high amount of energy, some enterprises are exploring energy-saving measures such as waste heat recovery. From an environmental perspective, the autoclaving technology may reduce the emissions of certain pollutants, but attention should still be paid to the management of steam emissions. Generally speaking, the autoclave is an important device for producing high-quality concrete and other building materials. Although the initial investment is relatively large, it can significantly improve production efficiency and product performance. With the development of technology, the design and operation of autoclaves are also constantly optimized to meet higher production and environmental protection requirements.

[0003] After a general autoclave is put into use, the inner cavity of the autoclave will become hot as the temperature rises, and the general inner cavity needs to be cooled down. Many autoclaves need to use water sources for watering and cooling, but the laying area of the liquid irrigation is not uniform enough, which will cause the autoclaving effect to fail to meet the standard.

[0004] Application No.: CN202022130924.7. The autoclave for the production of autoclaved aerated concrete slabs includes an autoclave. One side of the autoclave is fixedly provided with an air outlet. In the middle of the air outlet, an electromagnetic induction valve is fixedly provided. One end of the air outlet through the autoclave is fixedly connected with an aerosol mixing pipe. At the bottom side of the middle of the aerosol mixing pipe, a fog guiding pipe is fixedly connected. One end of the fog guiding pipe away from the aerosol mixing pipe is fixedly connected with an atomization chamber. For this autoclave for the production of autoclaved aerated concrete slabs, through the setting of the atomizer and the aerosol mixing pipe, water is injected into the atomization chamber through the water injection pipe until it submerges the atomizer. The atomizer is turned on to generate mist. The mist flows through the fog guiding pipe to the aerosol mixing pipe. The clean gas is lighter in mass and is discharged through the exhaust port opened at the top of the cone. However, when this equipment is in use, it cannot ensure that when the temperature inside the autoclave is too high, the spray structure can timely cool the inner cavity of the autoclave.

[0005] Therefore, in view of this, research and improvement are carried out in view of the existing deficiencies, and an autoclaving device for concrete production is proposed. Utility Model Content

[0006] The purpose of the present utility model is to provide an autoclaving device for concrete production to solve the problems raised in the above background technology.

[0007] To achieve the above purpose, the present utility model provides the following technical solutions: An autoclaving device for concrete production, including: an autoclave body, the top of the autoclave body is provided with a kettle head, the top of the kettle head is provided with a pressure gauge, and the upper end of the outside of the autoclave body is provided with an auxiliary structure;

[0008] The bottom end of the autoclave body is provided with a water outlet, and a heat filling structure is vertically arranged inside the autoclave body.

[0009] Further, the auxiliary structure includes a water guiding pipe, a water surrounding frame, a water storage tank and a water outlet pipe. The upper end of the outside of the autoclave body is surrounded and penetrated by the water guiding pipe. The top of the water guiding pipe is provided with the water outlet pipe. The top of the water outlet pipe is provided with the water surrounding frame. The top of the water surrounding frame is provided with the water storage tank. A cylindrical cavity is opened inside the water surrounding frame, which is convenient for the cooling liquid inside the water storage tank to be evenly introduced into the cavity inside the water surrounding frame.

[0010] Further, the contact gap between the water outlet pipe and the inner bottom end of the autoclave body is greater than the thickness of the water surrounding frame to prevent the cooling liquid from not being able to be discharged.

[0011] Further, the diameter of the upper end port of the water outlet pipe is larger than the diameter of the lower end port of the water outlet pipe, which is convenient for the cooling liquid to be gradually discharged inside the water outlet pipe.

[0012] Further, the heat charging structure includes a table-shaped frame, a soil-containing tank, small heat holes, large heat holes, an inner cavity and a top basin. The soil-containing tank is vertically arranged inside the autoclave body. A table-shaped frame is arranged at the top of the soil-containing tank. An inner cavity is vertically arranged inside the soil-containing tank. A top basin is arranged at the top of the inner cavity. Small heat holes are opened at the upper and lower ends of the outer side of the soil-containing tank. Large heat holes are annularly opened at the middle part of the outer side of the soil-containing tank. The ratio between the table-shaped frame and the top basin is two to one, which is convenient for the concrete liquid to be introduced into the inner cavity to the greatest extent.

[0013] Further, the area of the large heat holes is larger than that of the small heat holes, which is convenient for a large amount of heat to gather at the middle part of the outer side of the soil-containing tank.

[0014] Further, through holes are annularly opened at the bottom ends of the soil-containing tank and the inner cavity, which is convenient for the liquid formed by the hot gas to be discharged.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, the liquid inside the water storage tank passes through the inside of the water circulation frame. The liquid inside the water circulation frame flows into the water guide pipe through the water outlet pipe. The water guide pipe flows the liquid into the inside of the autoclave body. After the liquid is gradually stored between the soil-containing tank and the autoclave body, the liquid absorbs the heat generated inside the autoclave body. In this way, the heat generated inside the autoclave body will be absorbed.

[0017] 2. In the present utility model, the concrete liquid is poured into the inside of the table-shaped frame. The table-shaped frame allows the concrete material to enter the inner cavity inside the soil-containing tank. The large heat holes and small heat holes on the outer side of the soil-containing tank increase the contact with the steam. And the inner cavity and the top basin lengthen the storage length of the concrete material. In this way, the contact area between the concrete material and the steam is increased, which is convenient for improving the steaming effect of the concrete material.

[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0036] Such as Figures 1 - 16As shown in the figure, an autoclave device for concrete production includes: an autoclave body 1, a kettle head 5 is provided at the top of the autoclave body 1, a pressure gauge 3 is provided at the top of the kettle head 5, and an auxiliary structure 4 is provided at the upper end outside the autoclave body 1;

[0037] A water outlet 2 is provided at the bottom end of the autoclave body 1, and a heat filling structure 6 is vertically arranged inside the autoclave body 1.

[0038] As Figures 1 - 16 shown in the figure, an autoclave device for concrete production, the auxiliary structure 4 includes a water guide pipe 401, a water ring frame 402, a water storage tank 403 and a water outlet pipe 404. The upper end outside the autoclave body 1 is surrounded and penetrated by the water guide pipe 401. The top of the water guide pipe 401 is provided with the water outlet pipe 404. The top of the water outlet pipe 404 is provided with the water ring frame 402. The top of the water ring frame 402 is provided with the water storage tank 403. A cylindrical cavity is opened inside the water ring frame 402. When the outer shells of the autoclave body 1 and the soil storage tank 602 are too hot, the water storage tank 403 introduces the cooling liquid into the inner side of the water ring frame 402, and then the water ring frame 402 introduces the liquid into the water outlet pipe 404. The water outlet pipe 404 introduces the cooling liquid into the water guide pipe 401 again. The water guide pipe 401 stores the cooling liquid between the gaps of the soil storage tank 602 and the autoclave body 1. When the cooling liquid fills the space between the autoclave body 1 and the soil storage tank 602, at this time, the cooling liquid absorbs the heat generated between the autoclave body 1 and the soil storage tank 602:

[0039] Among them, the following effects and novel technologies are brought:

[0040] Closed-loop cooling system: This design creates a complete cooling cycle, starting from the water storage tank 403, passing through the water ring frame 402, the water outlet pipe 404, the water guide pipe 401, and finally returning to the gap between the autoclave body 1 and the soil storage tank 602. This closed-loop system can continuously provide cooling without frequent replacement of the cooling liquid, greatly improving the cooling efficiency and resource utilization rate;

[0041] Uniform cooling design: The cylindrical cavity design inside the water ring frame 402 is an innovation point. This design ensures that the cooling liquid can be evenly distributed throughout the system, avoiding problems of local overheating or insufficient cooling. Uniform cooling is crucial for maintaining the temperature consistency inside the autoclave body 1 and helps to improve product quality;

[0042] Direct heat absorption: The cooling liquid is introduced into the gap between the autoclave body 1 and the soil storage tank 602. This design allows the cooling liquid to directly contact the heat source, greatly improving the heat transfer efficiency. Compared with traditional external cooling methods, this direct contact cooling can absorb heat more quickly and effectively;

[0043] Anti-blocking mechanism: The contact gap between the outlet pipe 404 and the inner bottom end of the autoclave body 1 is greater than the thickness of the water circulation frame 402, which is a clever design. It ensures that even in extreme cases, the cooling liquid can flow out smoothly, preventing system blockage. This design increases the reliability and durability of the system and reduces maintenance requirements;

[0044] Flow optimization design: The outlet pipe 404 is designed with a larger upper port diameter than the lower port diameter. This conical structure is beneficial to the natural flow of the liquid. It utilizes the principles of gravity and liquid dynamics to ensure that the cooling liquid can flow smoothly from top to bottom, reducing energy consumption and improving the overall efficiency of the system;

[0045] Precise control of heat management: Through this complex cooling system, the operator can more precisely control the temperature inside the autoclave body 1. This is extremely important for process operations that require strict temperature control and can significantly improve product quality and production efficiency.

[0046] Energy-saving and environmental protection design: Due to the improved cooling efficiency, energy consumption is also reduced, meeting the energy-saving and environmental protection requirements of modern industry;

[0047] Enhanced safety: The efficient cooling system can better control the equipment temperature, reducing the risk of equipment overheating and improving the safety of the entire system. This is particularly important for the operation of the high-temperature and high-pressure autoclave body 1;

[0048] Highly adaptable modular design: Each component of this cooling system, such as the water storage tank 403, the water circulation frame 402, the outlet pipe 404, and the water guide pipe 401, is relatively independent. This modular design makes the system easy to maintain and upgrade. The size or performance of each component can be adjusted according to different needs, enhancing the flexibility and adaptability of the system.

[0049] Intelligent potential: The auxiliary structure 4 provides the possibility for integrating an intelligent control system. For example, temperature sensors and automatic control valves can be added to achieve automated and intelligent control of the cooling process.

[0050] This innovative cooling system design not only improves the efficiency and product quality of the autoclave body 1 but also provides new ideas for the development of industrial cooling technology. It comprehensively combines multiple aspects of fluid mechanics, thermodynamics, and engineering design and is a comprehensive and advanced cooling solution.

[0051] Such as Figures 1 - 16As shown in the figure, an autoclaving device for concrete production, the heat charging structure 6 includes a table holding frame 601, a soil holding tank 602, heat small holes 603, heat large holes 604, an inner cavity 605 and a top basin 606. A soil holding tank 602 is vertically arranged inside the autoclave body 1. A table holding frame 601 is arranged at the top of the soil holding tank 602. An inner cavity 605 is vertically arranged inside the soil holding tank 602. A top basin 606 is arranged at the top of the inner cavity 605. Heat small holes 603 are opened at the upper and lower ends on the outside of the soil holding tank 602. Heat large holes 604 are annularly opened at the middle part on the outside of the soil holding tank 602. The ratio between the table holding frame 601 and the top basin 606 is two to one. Concrete enters the inner cavity 605 at the middle part inside the soil holding tank 602 inside the autoclave body 1, and then the kettle head 5 is covered. When the autoclave body 1 receives steam, the steam enters the inside of the autoclave body 1 and is laid outside the inner cavity 605 through the heat small holes 603 and the heat large holes 604. Since the area of the heat large holes 604 is larger than that of the heat small holes 603, the heat large holes 604 accumulate a larger part of the heat at the middle part of the outer surface of the inner cavity 605, which is convenient for increasing the autoclaving efficiency of the concrete material in the middle section inside the inner cavity 605:

[0052] The following effects and novel technologies are brought:

[0053] Optimized heat distribution: By setting heat holes with different sizes on the outside of the soil holding tank 602, non-uniform distribution of steam heat is realized. The heat large holes 604 are concentrated in the middle part, while the heat small holes 603 are distributed at the upper and lower ends. This design enables the concrete material to obtain more heat in the middle section of the inner cavity 605. This heat distribution pattern very much meets the requirements of concrete autoclaving, because concrete usually needs to obtain more heat in the middle part to ensure complete curing. This design not only improves the autoclaving efficiency, but also may improve the overall quality and uniformity of the product;

[0054] Maximized contact area: The design of the inner cavity 605 and the top basin 606 cleverly extends the storage length of the concrete material. This design greatly increases the contact area between the material and the steam, thereby improving the heat transfer efficiency and autoclaving effect. A larger contact area means more uniform heat distribution and a faster autoclaving process, which may significantly shorten the production cycle and improve the production efficiency;

[0055] Optimized material flow: The 2:1 ratio design between the table holding frame 601 and the top basin 606 is another important innovation. This proportional relationship ensures that the concrete liquid can be introduced into the inner cavity 605 to the greatest extent, reduces material waste, and improves the material utilization rate. This not only improves the production efficiency, but also reduces the raw material cost. For large-scale production, this optimization can bring significant economic benefits;

[0056] Heat concentration design: The design where the area of the large thermal hole 604 is larger than that of the small thermal hole 603 concentrates heat at the middle part on the outer side of the soil container 602. This design further strengthens the autoclaving effect in the middle part. This heat concentration design may be particularly suitable for certain special concrete products that require high curing in the central area;

[0057] Drainage function: The design of the annular through-hole at the bottom of the soil container 602 and the inner cavity 605 is a detail innovation. This design allows the liquid condensed from steam to be quickly discharged, preventing water accumulation from affecting the autoclaving effect. This not only improves the product quality but also extends the equipment life and reduces the maintenance requirements.

[0058] Furthermore, other embodiments: Intelligent temperature monitoring system: High-precision temperature sensors are installed near the large thermal hole 604 and the small thermal hole 603 to monitor the temperature distribution in different areas in real time. This data can be input into the central control system, and according to the preset optimal temperature curve, the steam input volume and distribution are automatically adjusted to achieve precise temperature control. This system can adapt to different formulations of concrete and can even learn and optimize itself based on real-time data;

[0059] Dynamically adjustable thermal hole system: Design a mechanism that can dynamically adjust the size of the thermal holes during operation. For example, a variable aperture device controlled by a micro motor can adjust the size of the thermal holes in real time according to the requirements at different stages or different concrete formulations, so as to achieve more precise control of heat distribution. This system can greatly improve the adaptability and flexibility of the autoclave;

[0060] Structure of the multi-layer composite inner cavity 605: The inner cavity 605 is designed as a multi-layer composite structure, and thermal holes with different sizes and distributions, namely large thermal holes 604 and small thermal holes 603, are set between each layer. This design can create a more complex heat distribution pattern to meet the needs of different types of concrete. For example, a three-layer structure can be designed with smaller thermal holes at the bottom and top layers and larger thermal holes in the middle layer to achieve a heat gradient from the outside to the inside and ensure that the core of the concrete is fully heated;

[0061] Application of high-performance composite materials: Advanced composite materials are used to make the soil container 602 and the inner cavity 605, such as carbon nanotube-reinforced metal matrix composites. These materials not only have excellent thermal conductivity but also high strength and corrosion resistance, which can further improve the heat transfer efficiency, extend the equipment service life, and reduce the maintenance requirements.

[0062] Intelligent Automatic Feeding System: Design a feeding system that perfectly matches the Taisheng frame 601. This system can include precise metering devices, uniform distribution mechanisms, and intelligent control units. Through preset programs, the system can automatically adjust the feeding speed, quantity, and distribution pattern according to the requirements of different products, ensuring that the concrete materials enter the inner cavity 605 evenly in the best state. This not only improves production efficiency but also reduces human operation errors;

[0063] Multi-frequency Vibration System: Add a multi-frequency vibration device outside the soil storage tank 602. This system can generate vibrations with different frequencies and amplitudes, helping the concrete materials to be more evenly distributed in the inner cavity 605. At the same time, it can also remove air bubbles and improve the product density. The system can automatically adjust the vibration parameters according to the requirements of different stages. For example, use low-frequency and large-amplitude vibrations in the initial stage to help with distribution, and high-frequency and small-amplitude vibrations in the later stage to remove tiny air bubbles.

[0064] Efficient Steam Circulation and Recovery System: Design a complex steam circulation channel network to enable the unutilized steam to re-enter the system. This system can include steam collectors, heat exchangers, and recompression devices to make full use of the waste heat and greatly improve energy utilization efficiency. At the same time, this system can be considered to be combined with other heat energy requirements of the factory to achieve a greater range of energy optimization;

[0065] Phase Change Material Cooling System: Design a rapid cooling system using phase change materials outside the soil storage tank 602. The phase change materials can absorb and store heat during the autoclaving process and release it quickly when cooling is needed, achieving rapid and uniform cooling of the product. This system can not only improve production efficiency but also improve the internal structure of the product and reduce microcracks caused by thermal stress;

[0066] Modular and Customizable Design: Design the entire heat charging structure 6 into a series of standardized but combinable modules. This design allows users to select and combine different modules according to specific needs. For example, they can choose inner cavities 605 of different sizes, heat hole modules with different distributions such as small heat holes 603 and large heat holes 604, etc. The modular design not only facilitates cleaning and maintenance and rapid switching between different products but also provides great flexibility for customers, enabling them to customize the most suitable autoclave configuration according to production requirements.

[0067] The above implementation plans make full use of modern technologies such as artificial intelligence, high-performance materials, and precision control, pushing the original innovative design to a new height. They not only greatly improve the efficiency and product quality of the autoclave but also increase the flexibility and intelligence of the system. This comprehensive optimization will bring a revolutionary change to the concrete production industry and promote the entire industry to develop in a more efficient, more environmentally friendly, and more intelligent direction.

[0068] Working principle: When using the autoclave device for concrete production, first open the kettle head 5, then pour the concrete material into the interior of the autoclave body 1, and the concrete enters the inner cavity 605 in the middle of the inner side of the soil storage tank 602 in the autoclave body 1. Then cover the kettle head 5. When the autoclave body 1 receives steam, the steam enters the interior of the autoclave body 1 and is laid outside the inner cavity 605 through the heat small holes 603 and the heat large holes 604. Since the area of the heat large holes 604 is larger than that of the heat small holes 603, the heat large holes 604 accumulate a larger part of the heat in the middle of the outer surface of the inner cavity 605, which is convenient for increasing the autoclaving efficiency of the concrete material in the middle section of the inner cavity 605. When the outer shells of the autoclave body 1 and the soil storage tank 602 become too hot, the water storage tank 403 introduces the cooling liquid into the inner side of the circulating water frame 402, and then the circulating water frame 402 introduces the liquid into the water outlet pipe 404. The water outlet pipe 404 introduces the cooling liquid into the water guide pipe 401 again, and the water guide pipe 401 stores the cooling liquid in the gap between the soil storage tank 602 and the autoclave body 1. When the cooling liquid fills the gap between the autoclave body 1 and the soil storage tank 602, at this time, the cooling liquid absorbs the heat generated between the autoclave body 1 and the soil storage tank 602. This is the working principle of the autoclave device for concrete production.

[0069] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.
