Description

Technical Field

[0001] This utility model relates to the field of autoclaving technology for masonry blocks, and in particular to an autoclaving equipment for fly ash geopolymer masonry blocks. Background Technology

[0002] Fly ash, a major industrial solid waste from thermal power plants, is produced in enormous quantities annually. Its use in the preparation of geopolymer blocks (an alkali-activated inorganic cementitious material) offers advantages such as low carbon content, high strength, fire resistance, and corrosion resistance, representing an important development direction for green building materials. These blocks require autoclaving to accelerate the geopolymerization reaction and form a stable three-dimensional network structure.

[0003] For example, a calcium silicate board autoclaving device disclosed in CN220389802U includes a base, an autoclaving chamber mounted on the base, a curing mechanism and a support mechanism disposed within the autoclaving chamber. The autoclaving mechanism has a steam nozzle located at the top of the inner cavity of the autoclaving chamber, and a support frame located below the steam nozzle and rotatably disposed within the inner cavity of the autoclaving chamber via a drive mechanism, so that the calcium silicate board placed on the support frame can rotate. This invention increases the area of ​​the calcium silicate board exposed to steam curing by rotating the calcium silicate board through the rotatable support frame, enabling calcium silicate boards of different heights to receive optimal steam curing and ensuring curing effect. However, because this calcium silicate board autoclaving device lacks heat preservation measures, internal heat is easily lost, which affects the autoclaving effect of the product.

[0004] Therefore, a fly ash geopolymer block autoclaving equipment has now been developed that can use steam to keep the autoclave warm, thus preventing heat loss from affecting the autoclaving effect of the product. Utility Model Content

[0005] To overcome the shortcomings of existing calcium silicate board autoclaving equipment, such as lack of insulation measures and easy heat loss, which affects the autoclaving effect of the product, this utility model provides an autoclaving equipment for fly ash geopolymer blocks that can use steam to keep the autoclave warm and avoid heat loss affecting the autoclaving effect of the product.

[0006] The technical implementation scheme of this utility model is as follows: a fly ash geopolymer block autoclaving equipment, including a base, an autoclave, a sealing cover, an air inlet pipe, a circulation component and a rotating component. The autoclave is connected to the upper side of the base, the sealing cover is rotatably connected to the right side of the autoclave, the air inlet pipe is connected to the front side of the middle of the autoclave, the autoclave is equipped with a circulation component that enables steam circulation, and the autoclave is also equipped with a rotating component that enables steam to rotate and be ejected.

[0007] Optionally, a placement plate is provided on the inner side of the lower part of the autoclave.

[0008] Optionally, the sealing cap is provided with a handle.

[0009] Optionally, the circulation assembly includes a hose, a jet pipe, an outlet pipe, a control valve, and a circulation pipe. The inner sides of both the front and rear of the autoclave are rotatably connected to jet pipes, and the left and right sides of the jet pipes are connected to hoses. The hoses on the front side are all connected to the inlet pipe. An outlet pipe is connected to the upper side of the autoclave. A control valve is provided on the left side of the outlet pipe. A circulation pipe is connected inside the autoclave and is connected to the outlet pipe. The hoses on the rear side are all connected to the circulation pipe.

[0010] Optionally, the rotating assembly includes a motor, a rotating plate, a connecting rod, a sliding frame, a rack, and gears. The motor is connected to the left side of the autoclave, the rotating plate is connected to the output shaft of the motor, the connecting rod is rotatably connected to the rotating plate, the sliding frame is rotatably connected to the connecting rod, the rack is connected to the upper side of the sliding frame, the rack is slidably connected to the autoclave, and gears are connected to the left side of the jet pipes, all of which mesh with the racks.

[0011] Optionally, the control valve, motor, and processor are electrically connected via a control module.

[0012] The present invention has the following advantages: 1. The present invention delivers steam to the inlet pipe through a steam delivery pipe, so that the steam is evenly sprayed into the autoclave through the front hose and jet pipe to perform autoclaving curing on the blocks. Afterwards, the steam enters the outlet pipe, the control valve is closed, and the steam enters the circulation pipe to flow, thereby keeping the autoclave warm and avoiding heat loss that would affect the autoclaving curing effect of the product.

[0013] 2. This utility model starts the motor, drives the rotating plate to rotate, and pushes the sliding frame and rack to move back and forth through the connecting rod, so that the rack and gear mesh and drive the jet pipe to rotate and spray steam, thereby improving the uniformity of steam spray and improving the steam curing effect on the blocks.
