Description

Technical Field

[0001] The utility model relates to the technical field of building material production, in particular to an autoclave curing device for aerated concrete blocks based on the reuse of construction waste. Background Art

[0002] Aerated concrete blocks based on the recycling of construction waste utilize waste concrete, bricks, mortar and other materials generated during construction and demolition. After a series of treatments and processing, they are made into aerated concrete blocks with excellent performance. They are an environmentally friendly building material. During the processing of aerated concrete blocks, the aerated concrete blocks need to be autoclaved and cured. In the high-temperature and high-pressure steam environment, the various components in the material undergo chemical reactions, further improving the strength and performance of the blocks.

[0003] The utility model patent with the authorization announcement number CN205343411U discloses a steam curing device for autoclaved sand aerated concrete blocks, which includes a curing tank, a curing tank platform, and a kiln car for transporting blocks, and also includes a spray unit, a heating unit, and an exhaust unit arranged on the curing tank, wherein the spray unit is located above the heating unit, and the exhaust unit is located at the bottom of the curing tank. In this setting, spraying and electric heating are used to replace the traditional coal-fired steam boiler, and an exhaust unit is provided to exhaust the cold air already in the tank during air intake, which has the advantages of high curing efficiency, good effect, energy saving and environmental protection.

[0004] Although the steam curing device for autoclaved sand aerated concrete blocks has the advantage of high curing efficiency, it still has the following problems in actual use: the device is equipped with a kiln car for stacking blocks, but the kiln car needs manual or other equipment assistance to enter and exit the curing tank, which is time-consuming and labor-intensive in actual operation. In view of this, we propose an autoclave curing device for aerated concrete blocks based on the recycling of construction waste. Utility Model Content

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to 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 of 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.

[0029] This embodiment provides a technical solution:

[0030] Please refer to Figures 1 - 5As shown in the figure, an autoclave curing device for aerated concrete blocks based on the reuse of construction waste includes an autoclave 1. A curing chamber 10 is provided on the front end face of the autoclave 1. A cavity 11 is provided below the curing chamber 10. A connecting groove 12 is provided at the partition between the cavity 11 and the curing chamber 10. A threaded rod 14 is rotatably installed in the cavity 11. A motor 13 for driving the threaded rod 14 to rotate is installed on the rear end face of the autoclave 1. A bearing plate 2 that can move horizontally and is used for placing aerated concrete blocks is installed on the top of the partition. A connecting block 21 is installed at the rear end of the bottom of the bearing plate 2. The connecting block 21 passes through the connecting groove 12 and is threadedly connected to the threaded rod 14. A strip-shaped groove 22 is provided at the front end of the bearing plate 2. Two symmetrically arranged ear plates 29 are also fixed at the front end of the bottom of the bearing plate 2. A double-headed screw rod 23 is rotatably installed in the strip-shaped groove 22. Sliders 24 that can move horizontally are threadedly connected to both ends of the double-headed screw rod 23. Support plates 25 are provided below the sliders 24. Hinge seats 26 are hinged at both ends of the support plates 25. The upper hinge seats 26 are fixed to the sliders 24. Reversible support feet 27 are fixed at the lower hinge seats 26. A hinge groove 271 for hinging with the ear plate 29 is provided at the top of the support feet 27. A through groove 272 is provided at the bottom of the support feet 27. A roller 28 is rotatably installed at the through groove 272.

[0031] In this embodiment, guide rods 15 are fixedly connected to both sides of the threaded rod 14 in the cavity 11 through bolts. The guide rods 15 pass through the connecting block 21 and are slidably connected to the connecting block 21. The arrangement of the guide rods 15 plays a guiding role for the connecting block 21, ensuring the stability and smoothness of the horizontal movement of the connecting block 21.

[0032] In this embodiment, two guide rails 16 are also fixed to the top of the partition. Two sliding grooves 20 slidably connected to the guide rails 16 are provided at the bottom of the bearing plate 2. The arrangement of the guide rails 16 and the sliding grooves 20 increases the stability and smoothness of the horizontal movement of the bearing plate 2.

[0033] In this embodiment, the cross-sectional shape of the slider 24 is rectangular, and the size of the slider 24 is adapted to the size of the strip-shaped groove 22. This design is conducive to the smooth horizontal movement of the slider 24 in the strip-shaped groove 22, avoiding shaking caused by the rotation of the double-headed screw rod 23.

[0034] In this embodiment, one end of the double-headed screw rod 23 passes through the bearing plate 2, and a wrench 231 is coaxially key-connected to the end of the double-headed screw rod 23. It is convenient to rotate the double-headed screw rod 23 through the wrench 231, improving the convenience of operation.

[0035] In this embodiment, the threading winding directions at both ends of the double-headed screw rod 23 are opposite, and the end of the double-headed screw rod 23 is rotatably connected to the inner wall of the strip-shaped groove 22 through a bearing. When the double-headed screw rod 23 rotates, the sliders 24 on both sides can move relatively synchronously, which is conducive to the folding and unfolding of the support feet 27.

[0036] In this embodiment, two supports 17 are fixedly connected to the bottom of the autoclave 1 by bolts, and a rotatable sealing cover 18 is hinged at the front opening of the autoclave 1. The supports 17 play a supporting role for the autoclave 1, and the sealing cover 18 ensures the sealing performance of the autoclave 1.

[0037] It should be added that the cross-sectional shape of the wrench head 231 in this embodiment is a regular hexagon, and it is convenient to rotate the double-headed lead screw 23 by rotating the wrench head 231 with tools such as a wrench, which improves the convenience of operation.

[0038] It is worth noting that the motor 13 involved in this embodiment is an existing conventional technology and will not be elaborated here.

[0039] When it is necessary to send the building blocks into the autoclave 1 through the bearing plate 2, the user first rotates the wrench head 231 with a wrench, and the double-headed lead screw 23 rotates. The rotation of the double-headed lead screw 23 drives the sliders 24 on both sides to move synchronously towards the inside. The sliders 24 drive the support plates 25 to move at the same time, and the support plates 25 drive the support feet 27 to flip. The support feet 27 on both sides flip towards the inside synchronously. After the support feet 27 on both sides complete the flipping, stop rotating the wrench head 231. Then the user turns on the power supply of the motor 13, and the motor 13 starts to work. The output shaft of the motor 13 rotates to drive the threaded rod 14 to rotate, and the connecting block 21 moves backward along the two guide rods 15. The connecting block 21 drives the bearing plate 2 to move into the curing chamber 10 at the same time, and the bearing plate 2 sends the building blocks into the curing chamber 10 at the same time.
