Description

Technical Field

[0001] This invention relates to the field of autoclaving technology, and more specifically, to an energy-saving autoclaving device for concrete blocks. Background Technology

[0002] An autoclave, also known as a steam curing autoclave or pressure autoclave, is a large, heavy pressure vessel. Autoclaves have a wide range of applications, primarily used for the steam curing of building materials such as aerated concrete blocks, concrete pipe piles, sand-lime bricks, fly ash bricks, microporous calcium silicate boards, new lightweight wall materials, thermal insulation asbestos boards, and high-strength gypsum. The hydrothermal reaction of CaO—SiO2—H2O is completed within the autoclave. Autoclaves are also widely used in rubber products, wood drying and preservation, heavy metal smelting, oil and coal impregnation of refractory bricks, steam curing of composite glass, high-pressure treatment of chemical fiber products, high-temperature and high-pressure treatment of canned food, pulp cooking, cable vulcanization, fishing net shaping, and other production projects requiring pressure steam curing processes in the chemical, pharmaceutical, aerospace, insulation material, textile, and military industries.

[0003] The main drawbacks of autoclaves are: they typically use steam pipes to directly supply steam generated by a boiler into the autoclave. However, to maintain a constant temperature inside the autoclave, a continuous supply of hot steam is required to prevent the temperature from dropping. To prevent the pressure inside the autoclave from increasing indefinitely, some steam must be released while steam is being supplied. Since the released steam still carries a significant amount of energy, this results in substantial energy waste.

[0004] The unprecedented scale of China's current construction market has led to a supply shortage of new building materials such as lightweight bricks produced by autoclaves. This has spurred a rapid increase in the number and scale of companies using autoclaves to produce building materials in recent years. According to field investigations, after an autoclave with a diameter of 2 meters and a length of 31 meters completes its material curing process, the steam inside must be released to a specified level before the autoclave door can be opened. Currently, the venting method involves transferring steam from one autoclave to another via a gas pipe. This venting method is called "reverse venting." The system works when the air pressure in both autoclaves is equal. At this point, the air pressure in the two autoclaves is balanced. At this time, the steam in the autoclave in the venting state cannot be introduced into the other autoclave. Therefore, the steam can only be vented by releasing the gas. However, for an autoclave with a diameter of 2 meters and a length of 31 meters, the air pressure inside must be reduced to below 0.003 MPa before the safety interlock protection device allows the door to be opened. Otherwise, the air pressure inside the pressurized autoclave will cause an explosion. After the material curing process is completed, the time required for an autoclave with a diameter of 2 meters and a length of 31 meters to open the door from venting and releasing the gas is usually between 1.5 hours and 2.5 hours.

[0005] Chinese patent CN112025956A discloses a portable emergency respirator for emergency care. The patent application also discloses an autoclave, comprising a vessel body and a lid covering an opening on the side of the vessel body. The autoclave further includes a support, an opening / closing hydraulic cylinder, a rotating hydraulic cylinder, and a hydraulic pump station. The upper end of the support is hinged to the top of the opening on the side of the vessel body, and the lower end of the support is hinged to one end of the opening / closing hydraulic cylinder. The other end of the opening / closing hydraulic cylinder is hinged to the vessel body. All hinge axes are horizontally arranged and perpendicular to the central axis of the vessel body. The lower end of the support is also hinged to the central axis of the lid. During operation, the hydraulic pump station drives the rotating hydraulic cylinder to retract, thereby pushing the lugs to rotate forward, causing the lid to rotate forward around the central axis. The teeth of the vessel body and lid are misaligned. Then, the opening / closing hydraulic cylinder is extended, thereby driving the lid to flip upward and open. Then, the hydraulic pump station drives the opening and closing hydraulic cylinder to retract, which in turn drives the vessel lid to flip downwards and close. The rotating hydraulic cylinder extends, pushing the ear plate to rotate in the opposite direction, causing the vessel lid to rotate in the opposite direction around the central axis. The vessel body and the vessel lid mesh with each other. At the same time, the slider and slide groove structure ensures that the ear plate can move stably to the predetermined position. The hydraulic cylinder is subjected to stable force and smooth transmission. During the flipping of the vessel lid, only the ear plate moves with it. It is lightweight, has low inertia, and is sensitive to movement. Furthermore, when opening, the extension of the opening and closing hydraulic cylinder provides greater force, and when closing, the retraction of the opening and closing hydraulic cylinder provides buffering, preventing vibration caused by the rotation of the vessel lid, extending the service life of the equipment, reducing the labor intensity of personnel, and improving work efficiency.

[0006] In reproducing the aforementioned patent literature, the following problems were found: Before autoclaving concrete blocks, the building materials to be autoclaved need to be placed into the autoclave. Typically, a support is erected at one end of the autoclave to feed the materials in, making the workflow cumbersome for workers. Secondly, to maintain the pressure inside the autoclave, steam needs to be released, but steam contains a large amount of heat, resulting in significant energy waste.

[0007] To address these issues, we propose an energy-saving autoclaving device for concrete blocks. Summary of the Invention

[0008] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide an energy-saving autoclaving device for concrete blocks. The sealed components of the autoclaving device can be completed by transporting the autoclave body and track mechanism to the work site for splicing and welding. This facilitates transportation and track installation, reduces installation difficulty, improves portability, reduces bumps during transportation, reduces wear and tear on the autoclaving device, and lowers the risk of leakage, thereby solving the problems mentioned in the background art.

[0009] To achieve the above objectives, an energy-saving autoclaving device for concrete blocks includes: a vessel body covered with a vessel lid on both sides, wherein the vessel body is welded together by a cylindrical body mechanism and vessel flanges located on both sides of the cylindrical body mechanism, and a track mechanism for a moving or parking autoclaving trolley is laid at the bottom of the vessel body, and a steam port is also provided inside the vessel body, the steam port being evenly distributed along the longitudinal direction of the cylindrical body.

[0010] The cylindrical structure comprises multiple cylindrical units arranged longitudinally, with adjacent cylindrical units fitting tightly together. The track device comprises a long track for moving or parking the steam curing trolley and a support mechanism located at the bottom of the track structure. The support mechanism comprises multiple support units arranged longitudinally. The number of cylindrical units and support units is the same, and each support unit corresponds to each cylindrical unit.

[0011] In a preferred embodiment, the long track slides on the upper surface of the support mechanism, and a plurality of support units are welded to the inner wall of the corresponding cylindrical unit, with the ends of the plurality of support units facing each other.

[0012] The support mechanism includes multiple pairs of arc-shaped support fixing plates and multiple guide rail pads. Each pair of guide rail pads and one arc-shaped support fixing plate form a group and correspond to a group of support units. The number of arc-shaped support fixing plates is four. Each pair of arc-shaped support fixing plates is welded to both ends of the guide rail pads. There are three types of guide rail pads: guide rail pad one, guide rail pad two, and guide rail pad three.

[0013] In a preferred embodiment, the first guide rail pad is in two sets, with two guide rail pads in each set; the second and third guide rail pads are in multiple sets, with two guide rail pads in each set.

[0014] The two sets of guide rail pads are located on both sides of the bottom end of the long rail. Each set of guide rail pads includes a long support rod that is adapted to the long rail and a short support rod that is integrally connected to both ends of the long support rod. The outer diameter of the short support rod is smaller than that of the long support rod.

[0015] In a preferred embodiment, the guide rail pad rod two includes a support rod two adapted to the long rail of the track and an insert cylinder two integrally connected at both ends of the support rod two. The inner diameter of the insert cylinder two is the same as the outer diameter of the support rod one, and the length of the insert cylinder two is the same as the length of the support rod one.

[0016] In a preferred embodiment, the guide rail pad rod three includes a long support rod three adapted to the long rail of the track and a short support rod three integrally connected at both ends of the long support rod three. The inner diameter of the insert cylinder two is the same as the outer diameter of the short support rod three, and the length of the insert cylinder two is the same as the length of the short support rod three.

[0017] In a preferred embodiment, the track rail includes two sets of track rails for walking or parking the steam curing trolley and multiple connecting crossbars fixed at the opposite ends of the two sets of track rails, with the two sets of connecting crossbars distributed at equal intervals on the surface of the two sets of track rails.

[0018] The long track has two sets of blocking grooves at the bottom of the two sets of long track. Multiple sets of blocking plates are engaged inside the blocking grooves. Each set of blocking plates consists of two pieces. The two blocking plates are located on the surfaces of two arc-shaped support and fixing plates. The two sets of arc-shaped support and fixing plates are located on the same horizontal line, which is perpendicular to the longitudinal center line of the long track.

[0019] In a preferred embodiment, a set of bottom frames is attached to the bottom end of the vessel body, and the two sides of the bottom frames are flush with the two ends of the vessel body.

[0020] The bottom frame includes two sets of end support plates at both ends and multiple sets of arc-shaped support smooth plates between the two sets of end support plates. The two sets of end support plates and the multiple sets of arc-shaped support smooth plates are fixed together by two connecting circular long rods. The multiple sets of arc-shaped support smooth plates are parallel to each other, and the bottom ends of the multiple sets of arc-shaped support smooth plates are flush.

[0021] In a preferred embodiment, the cylindrical unit is arranged in a cylindrical shape that runs vertically through the interior. An arc-shaped groove is formed on the inner wall of the cylindrical unit. The cavity where the arc-shaped groove is located is a heat-insulating cavity. The inner cavity of the cylindrical unit is connected to the outside through a steam port.

[0022] The number of steam ports is in multiple groups, and each group contains multiple steam ports, which are arranged in a longitudinal linear pattern.

[0023] In a preferred embodiment, the multiple steam ports are respectively divided into steam inlets, steam outlets, and steam vents according to their functions. The steam inlets pass through the vessel body and are directly connected to the outside. The steam outlets are connected from the inner cavity of the vessel body to the insulation cavity. The insulation cavity is connected to the outside through the steam vents.

[0024] The technical effects and advantages of this invention are as follows:

[0025] 1. In this invention, both the vessel body and the track mechanism adopt a split structure. Each track unit corresponds to each support unit, and each support unit is located in the inner cavity of each cylindrical unit. Multiple support units are connected to each other, and multiple cylindrical units are spliced ​​together. The sealing composition of the autoclave can be completed by transporting the vessel body and track mechanism to the work site and splicing and welding them together. This facilitates transportation and track installation, reduces installation difficulty, improves the portability of transportation, reduces bumps during transportation, reduces the wear and tear of the autoclave, and reduces the risk of leakage of the autoclave.

[0026] 2. In this invention, in order to ensure that multiple guide rail pads can be spliced ​​into a single smooth rod that fits the long track rail, three types of guide rail pads are specially set up: guide rail pad one, guide rail pad two, and guide rail pad three. This ensures that the force on each part of the guide rail pad is uniform, and that the surfaces of the long track rail and the guide rail pad are completely in contact, avoiding stress concentration. This prevents the steam curing trolley from becoming unstable on the surface of the long track rail, or the guide rail pad from breaking due to long-term stress concentration, thus reducing the service life of the guide rail pads.

[0027] 3. In this invention, the track device is divided into a long track for moving or parking the steam curing trolley and a support mechanism located at the bottom of the track mechanism. The long track and the support mechanism are detachable structures, which can be used to clean the long track and the support mechanism separately, thereby improving the cleanliness of the cleaning. Furthermore, the long track and the support mechanism are also relatively sliding structures. The long track is moved to carry the steam curing trolley, and no additional support can be set up, thus reducing the overall structure of the steam curing device.

[0028] 4. In this invention, by setting an insulation wall on the inner wall of the cylindrical unit, the pressure inside the vessel device is stabilized, preventing excessive gas pressure inside the vessel device from causing an explosion. Secondly, the vessel device adopts a double-layer structure to avoid the rapid loss of temperature inside the vessel device 1, which would cause frequent delivery of high-temperature steam to the inside of the vessel device 1. This changes the steam delivery method from continuous delivery to intermittent delivery, saving energy. Furthermore, to prevent the pressure inside the vessel device 1 from continuously increasing and thus outputting water vapor to the outside of the vessel device 1, the output water vapor passes through the insulation cavity, realizing the reuse of heat and achieving the insulation effect. This avoids heat waste and realizes the secondary utilization of water vapor, achieving the purpose of energy saving. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Refer to the instruction manual appendix Figure 1-10An energy-saving autoclaving device for concrete blocks according to an embodiment of the present invention includes: a vessel body device 1, which is covered by a vessel cover device 2 on both sides. The vessel body device 1 is welded together by a cylindrical body mechanism and vessel body flanges located on both sides of the cylindrical body mechanism. Teeth are evenly distributed along the circumference of the vessel body flange. The cover device is welded together by a vessel cover flange, a beveled tooth plate, and a spherical cap. The vessel cover is suspended at the end of the vessel body by a lifting handle and a short shaft and can rotate freely horizontally or vertically. The teeth evenly distributed along the circumference of the vessel cover flange mesh with the teeth of the vessel body flange to seal the inner cavity of the cylindrical body. The vessel cover device 2 in this device is prior art and there is no improvement or creation in this technology, so the specific details are not shown. A track mechanism 3 for a walking or parking autoclaving trolley is laid at the bottom of the vessel. At the same time, a steam port 4 is also provided in the vessel body device 1. The steam port 4 is evenly distributed along the longitudinal direction of the cylindrical body.

[0042] The cylindrical structure includes multiple cylindrical units arranged longitudinally, with adjacent cylindrical units fitting tightly together. The track device includes a track mechanism 3 for moving or parking the steam curing trolley and a support mechanism 5 located at the bottom of the track mechanism 3. The support mechanism 5 includes multiple support units arranged longitudinally. The number of cylindrical units and support units is the same, and each support unit corresponds to each cylindrical unit.

[0043] In the above-mentioned operation, the autoclaving device for concrete blocks often uses an autoclave, which also includes a door opening mechanism, a hand-cranked reducer, a safety interlock device, supports, insulation layers, sealing devices, valves and instruments, etc. In the autoclaving production, it often uses a welded integrated autoclave body 1 and an autoclave cover 2 covering both sides of the autoclave body 1. This brings certain difficulties to transportation or later installation of tracks. In this design, a split structure is adopted, with each track unit corresponding to each support unit, and each support unit located in the inner cavity of each cylindrical unit. Multiple support units are connected to each other, and multiple cylindrical units are spliced ​​together. By transporting the autoclave body 1 and track mechanism 3 to the work site for splicing and welding, the sealing composition of the autoclave can be completed. This facilitates transportation and track installation, reduces installation difficulty, and improves the portability of transportation.

[0044] In some examples, the track mechanism 3 slides on the upper surface of the support mechanism 5, multiple support units are welded to the inner wall of the corresponding cylindrical unit, and the ends of the multiple support units are opposite each other.

[0045] The support mechanism 5 includes multiple pairs of arc-shaped support fixing plates 510 and multiple guide rail pads. Each pair of guide rail pads and one arc-shaped support fixing plate 510 form a group and correspond to a group of support units. There are four arc-shaped support fixing plates 510. Each pair of arc-shaped support fixing plates 510 are welded to both ends of the guide rail pads. There are three types of guide rail pads: guide rail pad one 520, guide rail pad two 530, and guide rail pad three 540.

[0046] In some examples, guide rail pad 1 520 is in two sets, with two guide rail pad 1 520 in each set; guide rail pad 2 530 and guide rail pad 3 540 are in multiple sets, with two guide rail pad 2 530 and two guide rail pad 3 540 in each set.

[0047] Two sets of guide rail pads 520 are located on both sides of the bottom end of the track mechanism 3. Each set of guide rail pads 520 includes a long support rod adapted to the track mechanism 3 and a short support rod that is integrally connected to both ends of the support rod. The outer diameter of the short support rod is smaller than that of the long support rod.

[0048] In some examples, the guide rail pad 2 530 includes a support rod 2 adapted to the track mechanism 3 and an insert cylinder 2 integrally connected at both ends of the support rod 2. The inner diameter of the insert cylinder 2 is the same as the outer diameter of the support rod 1, and the length of the insert cylinder 2 is the same as the length of the support rod 1.

[0049] In some examples, the guide rail pad 3 540 includes a long support rod 3 adapted to the track mechanism 3 and a short support rod 3 integrally connected at both ends of the long support rod 3. The inner diameter of the insert cylinder 2 is the same as the outer diameter of the short support rod 3, and the length of the insert cylinder 2 is the same as the length of the short support rod 3.

[0050] In the above technical solution, in order to ensure that multiple guide rail pads can be spliced ​​into a single smooth rod that fits the track mechanism 3, three types of guide rail pads are specially set: guide rail pad one 520, guide rail pad two 530, and guide rail pad three 540. This ensures that the force on each part of the guide rail pad is uniform, and that the surface of the track mechanism 3 and the guide rail pad are completely in contact, avoiding stress concentration. This prevents the steam curing trolley from becoming unstable on the surface of the track mechanism 3, or the guide rail pad from breaking due to long-term stress concentration, thus reducing the service life of the guide rail pads.

[0051] In some examples, the track mechanism 3 includes two sets of track rails 301 for moving or parking the steam curing trolley and multiple connecting crossbars 302 fixed at opposite ends of the two sets of track rails 301. The two sets of connecting crossbars 302 are distributed at equal intervals on the surface of the two sets of track rails 301.

[0052] The track mechanism 3 has two sets of blocking grooves 6 at the bottom of the two sets of long track rails 301. Multiple sets of blocking plates 7 are engaged inside the blocking grooves 6. Each set of blocking plates 7 consists of two pieces. The two blocking plates 7 are located on the surfaces of two arc-shaped support fixing plates 510. The two sets of arc-shaped support fixing plates 510 are located on the same horizontal transverse line, which is perpendicular to the longitudinal center line of the long track rail 301.

[0053] In the above scheme, the track mechanism 3 slides on the surface of the support mechanism 5. However, the sliding distance of the baffle plate 7 is limited by a certain length. The baffle plate 7 is arc-shaped. Therefore, no matter how much the track mechanism 3 overlaps with the support mechanism 5, the track mechanism 3 and the support mechanism 5 can be kept in close contact. Furthermore, setting the track mechanism 3 and the support mechanism 5 to be detachable and relative to the sliding mode makes it easy to separate and disassemble to clean the autoclave of concrete blocks, reducing the difficulty of cleaning and improving the precision of cleaning.

[0054] Secondly, when the steam curing trolley is pushed into the inner cavity of the autoclave 1 via the track mechanism 3 for steam curing, a support bracket is needed to push the steam curing trolley to the opening of the autoclave 1. In this design, the track mechanism 3 is pushed towards the outer cavity of the autoclave 1, and the other end of the track mechanism 3 is pushed to the ground and ground support, so as to push the steam curing trolley into the interior of the autoclave 1 without the need for additional support equipment.

[0055] In some examples, a set of bottom frames 8 are attached to the bottom end of the vessel body 1, and the two sides of the bottom frames 8 are flush with the two ends of the vessel body 1.

[0056] The bottom frame 8 includes two sets of end support plates 801 located at both ends and multiple sets of arc-shaped support smooth plates 802 located between the two sets of end support plates 801. The two sets of end support plates 801 and the multiple sets of arc-shaped support smooth plates 802 are fixed together by two connecting circular long rods 803. The longitudinal line of the connecting circular long rods 803 is parallel to the vessel body device 1. The multiple sets of arc-shaped support smooth plates 802 are parallel to each other, and the bottom ends of the multiple sets of arc-shaped support smooth plates 802 are flush.

[0057] The arc-shaped support smooth plate 802 supports the connection point of multiple cylindrical units, and places multiple cylindrical units on the bottom frame 8 for splicing support of multiple cylindrical units, which facilitates splicing, pouring and sealing of multiple cylindrical units. At the same time, it realizes the integrated connection between the vessel device 1 and the bottom frame 8 during the pouring process.

[0058] In some examples, the cylindrical unit is arranged in a cylindrical shape that runs vertically through the body. An arc-shaped groove is provided on the inner wall of the cylindrical unit. The cavity where the arc-shaped groove is located is a heat-insulating cavity. The inner cavity of the cylindrical unit is connected to the outside through the steam port 4.

[0059] There are multiple groups of steam inlets 4, and each group contains multiple steam inlets 4, which are arranged in a longitudinal linear pattern.

[0060] In some examples, multiple steam ports 4 are divided into steam inlets, steam outlets and steam vents according to their functions. The steam inlets pass through the vessel body 1 and are directly connected to the outside. The steam outlets are connected from the inner cavity of the vessel body 1 to the insulation cavity. The insulation cavity is connected to the outside through the steam vent.

[0061] In the above-mentioned operation, autoclaves typically use steam pipes to directly supply steam generated by a boiler into the autoclave. In this design, the steam pipe is welded to the steam inlet to introduce high-temperature steam into the inner cavity of the autoclave body 1 for autoclaving the concrete blocks. However, in practice, to maintain a constant temperature within the autoclave body 1, a continuous supply of high-heat steam is required to prevent temperature drop. To prevent the pressure within the autoclave body 1 from continuously increasing, a certain amount of steam needs to be discharged simultaneously with the introduction of steam. Since the discharged steam still carries a significant amount of energy... This results in significant energy waste. To address this issue, the device is equipped with a steam inlet, a steam outlet, and a steam vent. To maintain the internal temperature of the autoclave, the autoclave body 1 adopts a double-layer structure, preventing excessive temperature loss within the autoclave body 1 and thus avoiding frequent supply of high-temperature steam to the autoclave body 1. This changes the steam supply method from continuous to intermittent supply, saving energy. Secondly, to prevent the pressure inside the autoclave body 1 from continuously increasing and causing water vapor to be output to the outside of the autoclave body 1, the output water vapor passes through the insulation chamber, achieving heat reuse and insulation effects. This avoids heat waste while realizing the secondary utilization of water vapor, achieving energy-saving effects.

[0062] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
