Description

Technical Field

[0001] This utility model relates to a processing equipment for carbon-fixed ready-mixed concrete, belonging to the technical field of processing equipment for carbon-fixed ready-mixed concrete. Background Technology

[0002] The main functions of carbon-sequestered ready-mixed concrete include permanently sequestering carbon dioxide emitted from industrial processes while simultaneously improving the strength and durability of concrete. Its working principle involves collecting carbon dioxide from industrial emissions and injecting it into the concrete. This allows the carbon dioxide to react with the cementitious components and other alkaline components in the concrete, forming carbonate products that permanently solidify the carbon dioxide within the concrete. This technology not only achieves the sequestration and utilization of carbon dioxide but also improves the workability and compressive strength of the concrete.

[0003] In the existing process of preparing carbon-fixed ready-mixed concrete, carbon dioxide is simply introduced directly into the mixing tank through a gas pipe to mix with the concrete raw materials during the mixing process. However, the gas is light and rises, making it inconvenient to inject carbon dioxide gas into the concrete. In order to address the above shortcomings, this utility model proposes a processing equipment for carbon-fixed ready-mixed concrete. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a processing equipment for carbon-fixed ready-mixed concrete to solve the existing problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a carbon-fixed ready-mixed concrete processing equipment, the structure of which includes a frame, on which a mixing drum is vertically arranged, and a mixing mechanism is installed inside the cavity of the mixing drum. The top surface of the mixing drum is covered with a drum cover, and a feed inlet is opened at the right end of the drum cover, and a cap is hinged to the feed inlet. The left end of the mixing mechanism extends to the left side of the mixing drum and is connected to the main body of a carbon dioxide pressurization tank through a hose. A control box electrically connected to the mixing mechanism and the main body of the carbon dioxide pressurization tank is arranged on the left side of the frame.

[0006] The stirring mechanism includes a cross frame, and a rotating shaft assembly is vertically mounted in the middle of the cross frame. A synchronous belt drive assembly is connected to the upper end of the rotating shaft assembly. Multiple aeration stirring rods and multiple blades are alternately arranged on the shaft of the rotating shaft assembly, and the rotating shaft assembly is interconnected with each aeration stirring rod.

[0007] A further improvement is that the rotating shaft assembly includes a rotating seat, on which a gas filling rotating shaft is vertically mounted, and a universal joint is connected to the top of the gas filling rotating shaft, with an air intake horizontal pipe arranged on the universal joint.

[0008] A further improvement is that a first air pipe is provided in the middle of the top surface of the air-filling shaft, which is connected to the universal joint, and multiple air ports are provided on the left and right walls of the first air pipe, which are connected to the air-filling stirring rod one by one.

[0009] A further improvement is that each of the aeration stirring rods includes a crossbar, and two material distribution triangular prisms are integrally formed on the left and right sides of the crossbar. A second air pipe communicating with the air inlet is opened in the middle of the crossbar, and multiple small air filling holes are spaced apart on the bottom surface of the pipe wall of the second air pipe.

[0010] A further improvement is that the synchronous belt drive group consists of a motor, two synchronous belt gears, and a pulley meshing for transmission.

[0011] A further improvement is that the main body of the carbon dioxide pressurization tank is based on existing technology, and its structure will not be described in detail here.

[0012] The beneficial effects of the utility model are:

[0013] This utility model provides a carbon-fixed ready-mixed concrete processing equipment. Through the structural combination design of a frame, mixing drum, mixing mechanism, drum lid, feed inlet, outlet cover, carbon dioxide pressurization tank body, and control box, a carbon-fixed ready-mixed concrete processing equipment is constructed. The mixing drum of this equipment can provide a sealed cavity during mixing, while the mixing mechanism has dual functions of mixing and aeration. Carbon dioxide gas is pressurized and delivered through the carbon dioxide pressurization tank body, allowing the carbon dioxide gas to be directly added to the concrete raw materials during the mixing process, preventing the carbon dioxide gas from drifting upwards. Furthermore, the aeration orifice is oriented downwards, reducing the likelihood of clogging. This design is highly practical. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1-5 The present invention discloses a schematic diagram of a carbon-fixing premixed concrete processing equipment. The equipment comprises a frame 1, on which a mixing drum 2 is vertically mounted. A mixing mechanism 3 is fitted inside the cavity of the mixing drum 2. A lid 4 covers the top of the mixing drum 2, and a feed inlet 5 is provided at the right end of the lid 4. A cover 6 is hinged to the feed inlet 5. The left end of the mixing mechanism 3 extends to the left side of the mixing drum 2 and is connected to a carbon dioxide pressurization tank body 7 via a flexible hose. A control box 8, electrically connected to the mixing mechanism 3 and the carbon dioxide pressurization tank body 7, is located on the left side of the frame 1. The mixing mechanism 3 includes a crossbeam 31, on which a rotating shaft assembly 32 is vertically mounted. A synchronous belt drive assembly 33 is connected to the upper end of the rotating shaft assembly 32. Multiple aerated mixing rods 34 and multiple blades 35 are alternately arranged on the shaft of the rotating shaft assembly 32. The rotating shaft assembly 32 is interconnected with each aerated mixing rod 34.

[0021] The rotating shaft assembly 32 includes a rotating seat 321, on which a gas filling rotating shaft 322 is vertically mounted, and a universal joint 323 is connected to the top of the gas filling rotating shaft 322. An air intake horizontal pipe 324 is arranged horizontally on the universal joint 323.

[0022] The top surface of the gas-filling shaft 322 has a first air pipe 3221 that communicates with the universal joint 323. The left and right walls of the first air pipe 3221 are provided with multiple air ports 3222 that correspond to the gas-filling stirring rod 34.

[0023] Each of the gas-filling stirring rods 34 includes a crossbar 341, and two material-distributing triangular prisms 342 are integrally formed on the left and right sides of the crossbar 341. A second air pipe 343 communicating with the air port 3222 is opened in the middle of the crossbar 341. A plurality of small air-filling holes 344 are spaced apart on the bottom surface of the pipe wall of the second air pipe 343.

[0024] Working principle:

[0025] First, various concrete raw materials are poured into the mixing drum 2 through the feed inlet 5. Then, the lid 6 is closed to create a sealed space in the mixing drum 2. The synchronous belt drive group 33 drives the rotating shaft group 32 to rotate, causing each aerated mixing rod 34 and each blade 35 to rotate and mix the various concrete raw materials. Each blade 35 stirs the concrete raw materials upward. During the mixing process, a certain amount of carbon dioxide gas is injected into the main body of the carbon dioxide pressurization tank 7 through a pressurized method. The carbon dioxide gas flows out through the air inlet hose, air inlet horizontal pipe 324, universal joint 323, first air pipe 3221, air port 3222, second air pipe 343, and finally flows out from each aeration hole 344. This allows the carbon dioxide gas to be directly added to the concrete raw materials during the mixing process, making it less likely for the carbon dioxide gas to drift upward.
