Description

Technical Field

[0001] The present invention relates to the technical field of the production of environmentally friendly new building materials, autoclaved bricks, and particularly relates to an autoclaving device for environmentally friendly new building materials. Background Art

[0002] Autoclaved bricks are a kind of environmentally friendly new building materials that are light, porous, have good heat insulation and fire resistance, and can be nailed, sawn, planed, and have a certain seismic resistance; autoclaved bricks need to be autoclaved and cured using an autoclave.

[0003] The autoclave is a steel horizontal cylindrical device, which is opened and closed by a hand-operated speed reducer, and can also be opened and closed electrically, pneumatically, or hydraulically according to user requirements. The autoclave is equipped with a safety valve, a pressure gauge, a temperature measuring element, an inlet and outlet steam valve, a sealing ball valve, a steam trap, and other necessary valves and instruments. There is also a steam distribution pipe and a guide rail for supporting the trolley inside the autoclave. The specific operation is as follows: After the autoclaved bricks are grouped on the stop line in front of the autoclave, they are placed on the trolley, the autoclave door of the autoclave to be entered is opened, and then the trolley to be autoclaved is pulled into the autoclave by a winch for curing. After the curing is completed, the outlet autoclave door is opened, the bottom plate of the autoclave is pulled out, and the finished products on the trolley are lifted to the finished product warehouse by a bridge crane. However, for the above equipment, a large amount of steam will condense into water during autoclaving and curing, causing the energy-saving autoclaved bricks at the bottom to be soaked by the condensed water, which will affect the forming strength of the energy-saving autoclaved bricks. At the same time, during autoclaving, the autoclaving steam cannot contact the bottom of the autoclaved brick blank to be autoclaved, resulting in the bottom of the autoclaved brick blank to be autoclaved not being fully autoclaved, and causing the problem that the part of the autoclaved brick blank near the bottom due to insufficient autoclaving degree becomes waste.

[0004] Therefore, it is crucial to design an autoclaving device to solve the above problems. Summary of the Invention

[0005] The present invention aims to provide an autoclaving device for environmentally friendly new building materials to solve the problems that the brick blanks at the bottom of the existing autoclave are not fully autoclaved and may be soaked by condensed water.

[0006] An autoclaving device for environmentally friendly new building materials of the present invention includes an autoclave. The autoclave includes a horizontal cylindrical body. The two ends of the cylindrical body are provided with autoclave doors. The cylindrical body is connected to a steam pipe and an exhaust pipe. Inside the cylindrical body, there are a track and a steam distribution pipe. The steam pipe is connected to the steam distribution pipe. There are several conveying roller cylinders inside the cylindrical body. The two ends of the conveying roller cylinders are rotatably connected to the track. The conveying roller cylinders are hollow. The steam distribution pipe is provided with several branch pipes. The branch pipes are rotatably connected to the two ends of the conveying roller cylinders and penetrate through the conveying roller cylinders. A number of air holes are evenly distributed on the conveying roller cylinders. A water collecting tank is provided at the bottom of the cylindrical body. The steam distribution pipe is located in the water collecting tank. The water collecting tank is connected to a drain pipe that penetrates through the cylindrical body.

[0007] The working principle of the present invention, an autoclaving device for a new type of environmentally friendly building material of the present invention, is mainly used for aerated bricks. The conveying rollers are used in cooperation with the autoclave car. The bottom plate of the autoclave car is hollow. Place the brick blanks of the aerated bricks on the autoclave car, open the autoclave door, and use a crane or forklift to drag and pull the autoclave car into the cylinder. Since there are tracks in the cylinder and several conveying rollers are installed on the tracks, the conveying rollers can rotate. When the autoclave car is sent onto the conveying rollers, the rotation of the conveying rollers can reduce the resistance of the autoclave car to move. At the same time, due to the setting of the conveying rollers, more hollow parts can be provided at the bottom of the autoclave car. At the same time, in the present invention, there are several branch pipes on the steam distribution pipe. The branch pipes are rotatably connected to both ends of the conveying rollers and penetrate through the conveying rollers, and several air holes are evenly distributed on the conveying rollers. In this way, when the steam comes in, the steam will be released from the air holes on the conveying rollers connected to the branch pipes and contact the brick blanks to complete the steam curing of the bottom brick blanks; during the steam curing process, water droplets will form on the wall of the cylinder. In order to prevent the water droplets from flowing without direction and flooding the brick blanks due to excessive accumulated water, a water collecting tank is provided in the cylinder to make the water flow towards the water collecting tank, and the steam distribution pipe is arranged in the water collecting tank. Since the steam distribution pipe has a high temperature, the water in the water collecting tank can be evaporated, which can improve the steam curing effect and at the same time reduce the amount of accumulated water.

[0008] The beneficial effects of the present invention: The present invention is used for an autoclave for a new type of environmentally friendly building material, especially aerated bricks. By setting conveying rollers on the guide rails, connecting the conveying rollers with steam, and releasing the steam from the air holes on the conveying rollers, the bottom brick blanks can be steam cured. At the same time, the water collecting tank is set and the steam distribution pipe is placed in the water collecting tank, which can improve the steam curing effect while ensuring that the bottom brick blanks are also steam cured, and at the same time reduce the amount of accumulated water.

[0009] Furthermore, there are multiple drainage grooves arranged along the extending direction of the cylinder on the inner wall of the cylinder. In order to prevent the water droplets from flowing without direction, the drainage grooves are set to collect and uniformly drain the water droplets.

[0010] Furthermore, multiple drainage grooves extend towards the water collecting tank. The water droplets are collected and uniformly drained into the water collecting tank.

[0011] Furthermore, there are four drainage grooves, which are respectively arranged on both sides of the guide rail. In the present invention, only four drainage grooves need to be set, two on each side. The included angle between the two drainage grooves on the same side is 60 degrees, and the topmost drainage groove is not less than 45 degrees away from the top.

[0012] Further, one of the branch pipes is provided between every 2 to 5 adjacent conveying rollers. Since the air holes on the conveying rollers are distributed all over the conveying rollers, when the steam comes out of the air holes, it can be sprayed in all directions. Therefore, in order to reduce costs and processing difficulties, one branch pipe is arranged for every 2 to 5 adjacent conveying rollers.

[0013] In this application, one branch pipe is arranged for every 4 conveying rollers.

[0014] Further, the kettle door is hinged to the cylinder body through a hinge shaft, the hinge shaft is located at the bottom of the cylinder body, and a movable roller cooperating with the conveying roller is provided on the kettle door. In order to make the kettle car enter and exit the cylinder body more smoothly, a movable roller is arranged on the kettle door to cooperate with the movement of the kettle car.
