Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete block processing devices, in particular to an energy-saving autoclave for aerated concrete blocks. BACKGROUND

[0002] The autoclave is the core equipment in the production of aerated concrete blocks. It provides a high-temperature and high-pressure steam environment, allowing the cementitious materials in the concrete blocks to fully react, thereby improving the mechanical properties and durability of the concrete blocks. During the autoclaving process of the concrete blocks, uniform distribution of steam and effective heat transfer are crucial to the final performance of the concrete blocks. The performance of the autoclave directly affects the density, compressive strength, and yield of the aerated concrete blocks. Therefore, the structural design of the autoclave is an important factor in improving the quality of concrete blocks.

[0003] However, existing autoclaves require high sealing performance to maintain a high-pressure, airtight environment. The feed inlet is usually designed to be narrow, making it difficult to load and unload the concrete blocks, which are heavy. This often results in the blocks being stacked near the feed inlet, leading to uneven distribution of materials inside the autoclave. This uneven stacking can severely hinder the circulation of steam, resulting in a decrease in local heat transfer efficiency and preventing some blocks from achieving the desired autoclaving effect. In addition, uneven heating can cause stress distribution imbalance within the blocks, affecting the overall performance and yield of the products. Therefore, there is an urgent need for an energy-efficient and efficient autoclave that optimizes block placement, improves steam circulation, and improves autoclaving efficiency and the quality of concrete blocks.

[0034] The loading operation process of the steam autoclave is as follows: the autoclave body 101 is opened, the operator moves the concrete blocks from the two side feed ports to the top layer of the holding frame 201 in order, the holding shaft 202 rolls to assist the movement of the concrete blocks, so that the concrete blocks are smoothly pushed in; when the top layer of the holding frame 201 is fully loaded, the first servo motor 209 is started, the rotating shaft 207 is controlled to wind the pull belt 211, the control plate 204 of the top layer is controlled to vertically rise under the constraint of the mounting rod 203, and the top layer of the holding frame 201 connected therewith and the concrete blocks placed on the holding frame 201 are vertically raised, so as to expand the operation space of the middle layer of the holding frame 201, after the operation space is completely expanded, the first servo motor 209 is immediately closed, and the operator can perform the concrete block laying operation on the expanded middle layer of the holding frame 201.

[0035] Similarly, when the middle layer of the holding frame 201 is full, the first servo motor 209 is started again, at this time, the control panel 204 of the top layer will hook the middle layer control panel 204 through the slider 206, drive the two layers of holding frames 201 to rise synchronously, so as to expand the working space of the bottom layer holding frame 201; after the working space of the bottom layer holding frame 201 is completely expanded, the first servo motor 209 is closed again, and the concrete block placing work is carried out on the bottom layer holding frame 201 until the holding frame 201 is full, and the whole batch of concrete block placing work for autoclaving treatment is completed, finally, the layered mechanism forms a three-level space bearing structure; finally, the door 102 is closed, and the temperature and pressure controller 104 is controlled to carry out autoclaving treatment.

[0036] Conversely, when the concrete block needs to be unloaded, the reverse operation is performed, the concrete block on the bottom layer holding frame 201 is taken out from bottom to top, and the layered holding frame 201 is folded; through the above folding and expanding mode, the concrete block can be uniformly placed in the three-dimensional matrix in the kettle body 101, so that each concrete block can obtain sufficient and balanced heat exchange conditions, and the occurrence of local over-maintenance or under-maintenance phenomenon is avoided, thereby optimizing the water and heat reaction efficiency of the concrete block in the autoclaving maintenance stage, and improving the 28-day compressive strength index of the concrete block.

[0037] In combination with Figures 6-7 As shown in the figure, the autoclave also includes: an impeller circulating mechanism, the kettle body 101 is provided with an impeller circulating mechanism, the impeller circulating mechanism is arranged at the outer edge of the concrete block, and is used for continuously disturbing the high-temperature gas inside the kettle body 101 in the working state, breaking the temperature boundary layer effect formed by the three-dimensional placement of the concrete block, and improving the uniformity of the temperature field in the kettle body 101.

[0038] The impeller circulating mechanism includes: a support frame 301, the support frame 301 is fixedly installed on the inner wall of the kettle body 101; a rotating rod 302, the rotating rod 302 is rotatably installed on the support frame 301, and the rotating rod 302 is arranged on the four inner side walls of the kettle body 101 to form a horizontal annular structure, and the rotating rod 302 arranged in this way is provided with two layers; an impeller 303, the impeller 303 is fixedly installed on each rotating rod 302, and the impellers 303 are arranged in an equidistant array on the rotating rod 302, and the rotation of the rotating rod 302 promotes the gas flow in the kettle body 101 through the impeller 303; a second driving part group, the second driving part group is arranged in the kettle body 101 and connected with the rotating rod 302, and the second driving part group drives the rotating rod 302 to rotate.

[0039] The second driving part group comprises: a first transmission rod 304, the first transmission rod 304 is rotatably installed on the support frame 301, and two first transmission rods 304 are arranged at the right front side and the right rear side inside the kettle body 101 respectively; a first bevel gear 305, the first bevel gear 305 is fixedly installed on the first transmission rod 304 and the rotating rod 302, and the first transmission rod 304 and the rotating rod 302 are driven by the meshing effect between the first bevel gears 305.

[0040] Since the high-temperature steam or hot air enters the kettle body 101, a heat retention area is formed on the periphery of the three-dimensionally arranged concrete blocks due to the natural convection effect, so that the temperature gradient is unevenly distributed; therefore, the impeller circulating mechanism is additionally arranged, when the concrete blocks are subjected to autoclaving treatment, the first servo motor 209 is started, each rotating rod 302 is driven to rotate synchronously by the first transmission rod 304, and then the impeller 303 is driven to perform centripetal rotary motion, so that directional flow is generated in the outer edge area of the concrete block array in the kettle body 101 by driving high-position airflow, and a three-dimensional spiral circulating flow field is formed. This controlled fluid motion not only improves the convective heat exchange coefficient of the surface of the concrete block through the boundary layer thinning effect and the heat exchange efficiency, but also continuously transports the heat in the central high-temperature area to the edge low-temperature area by relying on the turbulent flow heat transfer mechanism, so as to improve the “core overheating-edge underheating” phenomenon commonly occurring in the traditional static curing process, and improve the mechanical property consistency of the concrete block products.
