[0002] Modification and enhancement equipment for the recycling of construction waste gypsum refers to specialized equipment that modifies waste gypsum (such as gypsum board, gypsum blocks, plaster, etc.) generated during construction, decoration, or demolition through physical, chemical, or mechanical means to improve its physical properties (such as strength, water resistance, stability, etc.) so that it can meet the requirements of different recycling scenarios (such as building material production, roadbed filling, agricultural applications, etc.).

[0003] After pretreatment such as crushing, screening, magnetic separation, and washing, existing waste gypsum needs to be physically mixed with modifiers (such as cement, lime, fly ash, slag, silica fume, and other cementing materials, or waterproofing agents, retarders, fibers, and other additives) to improve strength and stability through hydration reaction or physical encapsulation. However, traditional waste gypsum is prone to uneven mixing during physical stirring, which affects product quality. Utility Model Content

[0016] Please see Figure 1-4A modified and enhanced treatment device for recycling construction waste gypsum includes a base frame 1, a mixing tank 2 mounted on the base frame 1, and a circulation mechanism on the base frame 1 for circulating and conveying materials within the mixing tank 2. The circulation mechanism includes a first conveying cylinder 6 and a second conveying cylinder 9 for lifting and conveying materials. The circulation mechanism also includes a dispersion structure for dispersing powder during the circulation process, comprising a dispersion chamber 12 located at the top of the mixing tank 2. A rotating shaft 3 is rotatably mounted inside the mixing tank 2, and multiple sets of mixing and stirring blades 4 are mounted on the rotating shaft 3. A drive mechanism 5 is mounted on the base frame 1 for driving the rotating shaft 3 to rotate. The base frame 1 serves as the supporting structure for the entire device, fixing the mixing tank 2 and other auxiliary mechanisms to ensure the stability of the device during operation. The mixing tank 2 is the main reaction vessel, containing waste gypsum and... The mixture of modifiers provides a mixing space. The rotating shaft 3 rotates under the drive mechanism 5, causing the mixing and stirring blades 4 to mechanically stir the materials in the tank, promoting the initial mixing of waste gypsum and modifiers. The drive mechanism 5 is a combination of a motor and a reducer, providing stable power to the rotating shaft 3 and ensuring that the stirring intensity meets the process requirements. By combining the circulation of materials in the mixing tank 2 with the strong dispersion of the dispersing chamber 12, the materials in the mixing tank 2 continuously undergo the processes of stirring, conveying, and dispersing. Each cycle increases the contact area and contact opportunities between materials, allowing waste gypsum and modifiers to mix more thoroughly and effectively breaking up material agglomerates, avoiding uneven mixing in certain areas, ensuring full contact and mixing of waste gypsum and modifiers, making the material mixture more uniform, significantly improving the modification and enhancement effect, and ensuring the quality of the final product.

[0017] Please see Figure 1 and Figure 2A first conveyor cylinder 6 is arranged parallel to and below the mixing tank 2, and the inlet of the first conveyor cylinder 6 is connected to the inner bottom of the mixing tank 2. An auger conveyor shaft 7 is rotatably installed inside the first conveyor cylinder 6. A motor 8, whose output end is connected to one end of the auger conveyor shaft 7, is installed outside the first conveyor cylinder 6. A conveying hose 18 is installed at the outlet of the first conveyor cylinder 6, and the conveying hose 18 is connected to the inlet of the second conveyor cylinder 9. A second conveyor cylinder 9 is vertically arranged on one side of the mixing tank 2. An auger conveyor shaft 10 is rotatably installed inside the second conveyor cylinder 9. A motor 11, whose output end is connected to one end of the auger conveyor shaft 10, is installed outside the second conveyor cylinder 9. A conveying hose 19 is installed at the outlet of the second conveyor cylinder 9. The first conveyor cylinder 6 is arranged horizontally. Below the mixing tank 2, the material at the bottom of one side of the mixing tank 2 is conveyed to the conveying hose 18 by the rotation of the auger conveyor shaft 7, realizing the initial horizontal transfer of the material and preparing for subsequent lifting. The motor 8 drives the auger conveyor shaft 7 to rotate, providing power for material conveying. The conveying hose 18 connects the first conveying cylinder 6 and the second conveying cylinder 9. The flexible structure can buffer vibration and adapt to equipment installation errors. The second conveying cylinder 9 is arranged vertically. By the rotation of the auger conveyor shaft 10, the material is lifted from the low position to the dispersing chamber 12 at the top of the mixing tank 2, realizing the vertical conveying of the material and forming a circulation path. The motor 11 drives the auger conveyor shaft 10 to rotate, providing power for material lifting. The conveying hose 19 connects the second conveying cylinder 9 and the dispersing chamber 12, guiding the lifted material into the dispersing mechanism.

[0018] Please see Figure 3 and Figure 4 The mixing tank 2 has a dispersing chamber 12 connected to its interior at the top. The top of the dispersing chamber 12 has a feed end, and one end of the conveying hose 19 is connected to the feed end of the dispersing chamber 12. Inside the dispersing chamber 12 are two sets of guide plates 13, and the bottom of each set of guide plates 13 has multiple sets of dispersing teeth 14. A rotating shaft 15 is rotatably mounted inside the dispersing chamber 12, and multiple sets of stirring teeth 16 that can cooperate with the dispersing teeth 14 are mounted on the rotating shaft 15. A first motor 17 is mounted outside the dispersing chamber 12, and the output end of the first motor 17 is fixedly connected to one end of the rotating shaft 15. The dispersing chamber 12 is a material... The core area for material dispersion receives the circulating material and further refines and disperses it through its internal structure. The guide plate 13 guides the material so that it can better enter the dispersion area for dispersion. The dispersion teeth 14 are fixed to the bottom of the guide plate 13 and are arranged in a comb-like shape to initially cut and disperse the falling material clumps. The rotating shaft 15 rotates under the drive of the first motor 17, driving the stirring teeth 16 to rotate at high speed. The stirring teeth 16 and the dispersion teeth 14 are staggered to form a shear force field, further dispersing the agglomerates in the material. The first motor 17 provides power to the rotating shaft 15 to ensure that the stirring teeth 16 reach the speed required for effective dispersion.

[0019] Working principle: After the equipment is started, the motor and reducer combination in the drive mechanism 5 drives the rotating shaft 3 to rotate. The mixing and stirring blades 4 on the rotating shaft 3 begin to mechanically stir the waste gypsum and modifier in the mixing tank 2, achieving preliminary mixing. Under the action of gravity, the mixed material enters the first conveying cylinder 6 from the bottom of the mixing tank 2. The motor 8 outside the first conveying cylinder 6 drives the auger conveying shaft 7 to rotate, conveying the material horizontally along the first conveying cylinder 6 and sending it to the feed inlet of the second conveying cylinder 9 through the conveying hose 18. The motor 11 outside the second conveying cylinder 9 drives the auger conveying shaft 10 to rotate. The material is vertically lifted from a low position to the dispersing chamber 12 at the top of the mixing tank 2. After entering the dispersing chamber 12, the material is first guided by the guide plate 13. During the falling process, the dispersing teeth 14 initially cut and disperse the material clumps. At the same time, the first motor 17 drives the second rotating shaft 15 to rotate. The stirring teeth 16 on the second rotating shaft 15 and the dispersing teeth 14 rotate at high speed, forming a strong shearing force field, which further disperses and refines the agglomerates in the material. The dispersed material falls back into the mixing tank 2 from the outlet of the dispersing chamber 12 and participates in the mixing again. This cycle is repeated until the ideal modification and enhancement effect is achieved.
