Description

Technical Field

[0001] The present invention relates to the field of building materials, and particularly relates to an autoclaving device for the blank of aerated concrete blocks. Background Art

[0002] An autoclave, also known as a steam curing kettle or autoclave for autoclaving, is a large pressure vessel with a large volume and heavy weight. The autoclave has a very wide range of uses and is widely used in the autoclave curing of building materials such as aerated concrete blocks, concrete pipe piles, grey sand bricks, coal ash bricks, micro-porous calcium silicate boards, new lightweight wall materials, heat-insulating asbestos boards, high-strength gypsum, etc.; for example, the patent numbers CN115319902A and CN110624478A in the prior art disclose similar structures.

[0003] In the autoclaving process, since a large amount of steam needs to be filled into the cylinder, the steam is usually concentrated near the discharge port, and the heat is easily accumulated in the upper part of the cylinder. Especially at the bottom of the two ends of the autoclave door, there is less hot steam, the temperature of the steam alone on the cylinder wall is lower, and the heat preservation performance of the cylinder is poor, resulting in possible differences in temperature and pressure, and the quality of the same batch of aerated concrete blanks is inconsistent, such as fluctuations in performance indicators such as strength and density. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide an autoclaving device for the blank of aerated concrete blocks, so as to solve the technical problems of uneven autoclaving gas inside the cylinder and less hot gas at the bottom of both ends of the cylinder.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

An inner sealing layer is further provided on the inner wall of the door teeth. The inner sealing layer is made of silicone rubber material, and the hardness of the inner sealing layer is 50D.

[0008] Preferably, the electronic control module includes a speed reducer and a drive motor inside. A meshing tooth is provided on the side surface of the ring inside the outer ring. A transmission gear is provided between the meshing tooth and the electronic control module.

Specific Embodiment

[0026] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0027] Embodiment 1

[0028] As Figure 1-8 shown, the present invention provides an autoclave device for the embryo of aerated concrete blocks. The conventional main structure includes a cylinder body 1 and a kettle door 2. An air inlet 101 for entering steam is provided on the surface of the cylinder body 1. Fixed rings 102 are provided at both ends of the cylinder body 1. A track 103 provided inside the cylinder body 1 is for the entry of the concrete block trolley. An opening mechanism is provided between the cylinder body 1 and the kettle door 2, so that after the cylinder body 1 and the kettle door 2 are opened, the concrete block trolley can enter from the track 103. Subsequently, the kettle doors 2 at both ends of the cylinder body 1 are closed, and steam is discharged from the air inlet 101 to achieve the autoclave effect on the concrete blocks. A safety valve and a relief valve are also provided on the surface of the cylinder body 1 to keep a certain thermal pressure inside the cylinder body 1.

[0029] Further, an outer ring 3 is mounted on the surface of the fixing ring 102, a door ring 4 is arranged on the inner side of the kettle door 2, the outer ring 3 and the door ring 4 are fitted and sealed. A horizontal pipe 5 is mounted on the upper side inside the cylinder body 1, an arc pipe 501 is arranged at the bottom end of the horizontal pipe 5, the arc pipe 501 is mounted against the inner wall of the cylinder body 1, an air outlet 502 is arranged at the bottom side of the arc pipe 501 facing the center, and the arc pipe 501 is symmetrically arranged left and right. A wind direction row 6 is mounted at the center of the inner wall of the cylinder body 1, and the air outlet of the wind direction row 6 faces both ends of the cylinder body 1. After the two ends of the kettle door 2 are sealed and installed, the steam entering from the air inlet 101 will be dispersed to different arc pipes 501 from the horizontal pipe 5, and discharged from the arc pipe 501 along the inner wall of the cylinder body 1 to the lower air outlet 502, so that the inner wall of the cylinder body 1 is heated during the process of the hot steam entering, and the hot air at the outermost part of the cylinder body 1 is always in a relatively high temperature state. After the hot steam is discharged from the bottom, due to the principle of hot air rising, it will gradually gather at the top of the cylinder body 1. At the relatively far kettle door 2, and at the bottom of the kettle door 2, the hot air flow is the least. Therefore, a wind direction row 6 in the middle is designed. When the hot steam is discharged from the air outlet 502, the wind direction row 6 will intermittently blow the air flow from the middle to both ends of the cylinder body 1, so that the hot steam diffuses from the bottom of the cylinder body 1 to both sides, enabling the building blocks at the kettle door 2 to also withstand higher temperature and pressure.

[0030] The wind direction row 6 is externally connected to an air pump, and the inside of the air pump includes a heating module. The air outlet of the wind direction row 6 is located inside the air outlet 502.

[0031] Specifically, after the user sets the air pump externally connected to the cylinder body 1, the clock module included in the air pump will adjust the action interval of the air pump. Subsequently, after the concrete block trolley is placed into the cylinder body 1 and the kettle door 2 is sealed, the steam device connected to the air inlet 101 will continuously discharge hot steam. The hot steam will enter the horizontal pipe 5 from the air inlet 101, then be dispersed to a plurality of arc pipes 501, and be transmitted downward until it is discharged from the air outlet 502. Since a wind direction row 6 is arranged at the center of the cylinder body 1, when the air pump intermittently sends hot air flow to the wind direction row 6, the wind direction row 6 disperses the hot steam from the bottom of the cylinder body 1 to the kettle door 2, so that the space near the kettle door 2 can also intermittently receive the fumigation of the hot steam, enabling the concrete blocks at both ends to also obtain a good fumigation effect.

[0032] Embodiment 2

[0033] The difference from Embodiment 1 is that, as Figure 4-6 shown, an electronic control module 301 is arranged on the side surface of the outer ring 3, a ring 7 is slidably embedded inside the outer ring 3, ring teeth 701 are arranged on the surface of the ring 7, door teeth 401 protrude from the door ring 4, the door teeth 401 are correspondingly fitted with the ring teeth 701 from the inside, and an inner sealing layer 402 is further arranged on the inner wall of the door teeth 401. The inner sealing layer 402 is made of silicone rubber material, and the hardness of the inner sealing layer 402 is 50D.

[0034] The electronic control module 301 internally includes a speed reducer and a drive motor. Meshing teeth are provided on the side surface of the ring 7 located inside the outer ring 3. A transmission gear 302 is provided between the meshing teeth and the electronic control module 301. A groove 702 is provided on the side surface of the ring tooth 701, and a protrusion 403 is correspondingly provided on the side surface of the gate tooth 401. A cotton layer 404 is coated on the surface layer of the gate tooth 401.

[0035] An extrusion layer 703 is provided on the side surface of the groove 702 close to the gate tooth 401. The extrusion layer 703 is made of polytetrafluoroethylene material.

[0036] The electronic control modules 301 are arranged in pairs. Control buttons are provided on the surface of the electronic control module 301, and the control buttons are used to control the locking of the kettle door 2.

[0037] The cotton layer 404 is made of polyurethane sponge material.

[0038] Specifically, since the inside of the cylinder body 1 is always in the state of being fumigated by hot steam, the internal pressure will increase, and the hot air flow will leak out from the gap of the kettle door 2 with poor sealing, which not only increases the danger level of the equipment, but also causes the internal noise to be transmitted to the outside.

[0039] Therefore, a door ring 4 is provided on the kettle door 2, an outer ring 3 is provided on the fixing ring 102, a protruding gate tooth 401 is provided at the door ring 4, and an inner sealing layer 402 connected to the door ring 4 is provided inside the gate tooth 401. As Figure 4-8 shown, when the ring tooth 701 of the ring 7 on the outer ring 3 is engaged with the gate tooth 401, the electronic control module 301 can act, enabling the transmission gear 302 to drive the meshing teeth to rotate the ring 7 until the groove 702 of the ring tooth 701 is annularly engaged with the protrusion 403 of the gate tooth 401. During the engagement process, the cotton layer 404 of the ring tooth 701 will be squeezed, causing the cotton layer 404 to concentrate in the gap.

[0040] An extrusion layer 703 is further provided inside the groove 702, which is mainly used to provide a certain elasticity when axially stressed. That is, when the inside of the cylinder body 1 is pressurized, the kettle door 2 structures at both ends are the first to be pressurized. The kettle door 2 will continuously be stressed outward due to the pressure. At this time, the buckling structure of the groove 702 and the protrusion 403 will assist the door opening structure to bear the overall stress effect. While the inner sealing layer 402, the cotton layer 404, and the extrusion layer 703 are under pressure, the inner sealing layer 402 will fill the gap between the groove 702 and the protrusion 403 from the side, and the cotton layer 404 and the extrusion layer 703 mainly fill the gap at the connection, reduce the noise transmitted from the inside, and avoid the phenomenon that the protrusion 403 and the groove 703 are deformed due to excessive bearing force, resulting in the generation of gaps.

[0041] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
