[0025] Reference Figures 1-5 A homogenization tank for modifying crack-resistant recycled concrete matrix fibers includes a tank body 1. A feed hopper 2 is fixedly sleeved on the inner circular wall of the feed inlet of the tank body 1. A PLC controller is fixedly installed on the outer circular wall of the tank body 1. The tank body 1 also includes a mixing component, which is disposed on the inner circular wall of the tank body 1 and is used to fully mix the matrix fibers. The mixing component includes: a rotating shaft 3, which is disposed on the inner circular wall of the tank body 1. Two agitators 6 are fixedly installed on the outer circular wall of the rotating shaft 3. A spiral plate 5 is fixedly sleeved on the outer circular wall of the rotating shaft 3. A fixing ring plate 4 is disposed on the inner circular wall of the tank body 1. Several fixing holes 16 are opened on the top surface of the fixing ring plate 4 and the fixing ring plate 4 is fixedly sleeved with the agitators 6. An activation component is disposed on the top surface of the tank body 1 and is used to perform surface activation on the fibers.

[0026] In use, the recycled material is poured into the tank 1 through the feed hopper 2. The recycled material falls on the top surface of the fixed ring plate 4. The recycled aggregate is rotated by the rotating fixed ring plate 4. The surface of the aggregate is evenly moistened by the atomized water spray system. The accumulated recycled aggregate falls down to the bottom of the fixed ring plate 4 at a 25-degree slope. The rotating spiral plate 5 rolls the recycled material upward. The stirring frame 6 stirs the recycled material to achieve full mixing of fibers and eliminate fiber clumping.

[0027] In this embodiment, the activation component includes: a first circular through hole, which is opened on the top surface of the tank 1; a fixed chamber 12 is fixedly sleeved on the inner circular wall of the first circular through hole; a limiting groove 17 is opened on one side of the fixed chamber 12; a movable valve plate 13 is movably sleeved inside the limiting groove 17; a feeding hopper 10 is fixedly installed on the top surface of the fixed chamber 12; a plurality of second circular through holes are opened on the outer circular wall of the feeding hopper 10; an ultrasonic transducer 11 is fixedly sleeved on the inner circular wall of the second circular through hole; the ultrasonic transducer 11 is used in conjunction with an ultrasonic generator control host; in order to enable the ultrasonic transducer 11 to fully activate the fiber, the ultrasonic transducer 11 can be staggered; the feeding hopper 10 is not limited to the style shown in the figure; the depth of the feeding hopper 10 can be reduced so that the ultrasonic transducer 11 is aligned with the fiber, as long as the activation effect can be improved.

[0028] When in use, the fiber is put into the feeding hopper 10 and several ultrasonic transducers 11 are activated to activate the surface of the fiber: the high temperature and high pressure environment can promote the breaking of chemical bonds on the fiber surface and generate active groups (such as hydroxyl and carboxyl groups), which enhances the chemical bonding with the recycled material matrix and avoids the fiber from directly entering the main tank, which would lead to dispersion difficulties. The movable valve plate 13 is manually pulled down along the limiting groove 17 to the inside of the tank 1, and the pulse solenoid valve of the jet pipe 9 is activated to spray out a pulse airflow to blow the fiber and improve the dispersion effect.

[0029] In this embodiment, two rotating shovels 14 are fixedly installed on the outer circular wall of the rotating shaft 3. The rotating shovels 14 are fixedly installed with the stirring frame 6. A third circular through hole is opened on the outer circular wall of the tank body 1. A water inlet pipe 7 is fixedly sleeved on the inner circular wall of the third circular through hole. Several nozzles 8 are connected through the outer circular wall of the water inlet pipe 7. A fourth circular through hole is opened on the outer circular wall of the tank body 1. A jet pipe 9 is fixedly sleeved on the inner circular wall of the fourth circular through hole. A drive motor 15 is fixedly installed on the top surface of the tank body 1. The drive motor 15 is electrically connected to the PLC controller. The bottom surface of the drive shaft of the drive motor 15 is fixedly installed with the rotating shaft 3. The cross-section of the fixed ring plate 4 is inverted "V" shape, and the slope from the outside to the inside is 25 degrees.

[0030] In use, the rotating shovel 14 can scrape the bottom of the tank 1 to prevent sedimentation and uneven mixing. Water is sprayed through the water inlet pipe 7 and the nozzle 8 to rinse and clean the top surface of the fixed ring plate 4.

[0031] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0032] When the user needs to mix the fiber with the recycled concrete material in the tank 1, the drive motor 15 is started to drive the rotating shaft 3 to rotate, which in turn drives the spiral plate 5, the fixed ring plate 4, and the agitator 6 to rotate, thus feeding the fiber into the feeding hopper 10. Several ultrasonic transducers 11 are then activated to surface-activate the fiber: the high temperature and high pressure environment can promote the breaking of chemical bonds on the fiber surface, generating active groups (such as hydroxyl and carboxyl groups), enhancing the chemical bonding with the recycled material matrix, and preventing the fiber from directly entering the tank 1, which would lead to dispersion difficulties. The jet pipe 9 is connected to the pulse solenoid valve, and the pulse solenoid valve (with a pulse controller) is connected to the air pump outlet pipe. The water inlet pipe 7 is connected to the solenoid valve, and the solenoid valve is connected to the booster water pump. The booster water pump is started, and the solenoid valve is opened to allow water to enter the several nozzles 8 through the water inlet pipe 7 and be atomized and sprayed out. The recycled material is poured into the tank 1 through the feeding hopper 2, and the recycled material falls on the top surface of the fixed ring plate 4. The recycled aggregate is carried by the rotating fixed ring plate 4. The aggregate surface is evenly moistened by the atomized water spray system. The accumulated recycled aggregate falls down to the bottom of the fixed ring plate 4 at a 25-degree slope. The movable valve plate 13 is manually pulled down along the limiting groove 17 into the tank 1. At the same time, the pulse solenoid valve of the jet pipe 9 is activated to spray pulsed airflow to blow the fibers, improving the dispersion effect. After the fibers fall to the bottom of the fixed ring plate 4, the rotating spiral plate 5 rolls the recycled material upward, and the stirring frame 6 stirs the recycled material to achieve full mixing of fibers and eliminate fiber agglomeration. This achieves the effect of fully mixing the matrix fibers and the recycled concrete. The fiber surface is activated by the ultrasonic transducer 11 to prevent the fibers from directly entering the tank 1 and causing dispersion difficulties. The atomized water spray system evenly moistens the aggregate surface, reduces the difference in water absorption of aggregates, and avoids affecting fiber dispersion and concrete hardening quality. The pulsed airflow blows the dispersed fibers in conjunction with the stirring blades and spiral plate 5 to prevent fiber agglomeration or local enrichment and ensure the mixing effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
