[0034] The utility model provides a waste treatment device 100 .

[0035] Please refer to Figure 1 In some embodiments of the utility model waste treatment device 100, the waste treatment device 100 comprises:

[0036] A grinding device 10, for grinding solid waste to prepare waste particles;

[0037] A slurry processing device 20, which is disposed downstream of the grinding device 10 and is used to receive waste particles and prepare the waste particles into a slurry mixture;

[0038] An ultrasonic treatment device 30, which is disposed downstream of the slurry treatment device 20, and is used to receive the slurry mixture and perform ultrasonic treatment on the slurry mixture to weaken the direct adhesion of the waste particles in the slurry mixture; and

[0039] The magnetic separation device 40 is disposed downstream of the ultrasonic treatment device 30 and is used to receive the slurry mixture and perform magnetic separation treatment on the slurry mixture to separate the magnetic substance and the non-magnetic substance in the slurry mixture from each other.

[0040] In this embodiment, the waste treatment equipment 100 includes a grinding device 10, a slurry treatment device 20, an ultrasonic treatment device 30 and a magnetic separation device 40 which are arranged in sequence. Among them, the grinding device 10 can pre-treat solid waste, and the solid waste includes magnetic substances such as magnetic minerals, and also includes non-magnetic substances such as coal. After the solid waste is ground into particles with smaller particle size by the grinding device 10, the slurry treatment device 20 can mix the waste particles with water or other appropriate liquids in appropriate amounts to prepare a slurry mixture with an appropriate solid-liquid ratio. The ultrasonic treatment device 30 can perform ultrasonic treatment on the slurry mixture for a predetermined time, frequency and intensity to weaken the waste particles in the slurry mixture, and can separate the coal particles adhering to the magnetic mineral particles. Finally, the magnetic separation device 40 performs magnetic separation treatment on the slurry mixture after ultrasonic treatment, so that the magnetic substances and non-magnetic substances in the slurry mixture are separated from each other, so that the different types of waste substances after separation can be recycled and processed accordingly in the subsequent process.

[0041] It should be noted that in the related art, the waste treatment equipment 100 generally includes a particle grinding device 10 and a magnetic separation device 40, which can be used to separate waste containing magnetic minerals. Among them, the particle grinding device 10 can pre-process the waste into smaller particles, and the magnetic separation device 40 can use the magnetic properties of different types of particles to separate the magnetic substances in the particles from the non-magnetic substances. Since there is a large adhesion between the magnetic mineral particles and the coal particles in the waste particles, the magnetic separation device 40 of the waste treatment equipment 100 requires a higher magnetic field strength and a longer processing time to magnetically separate the waste particles, and the magnetic separation efficiency is low.

[0042] Therefore, it can be understood that the technical solution of the utility model, the waste treatment equipment 100 includes a grinding device 10, a slurry treatment device 20, an ultrasonic treatment device 30 and a magnetic separation device 40 arranged in sequence. Compared with the technical solution in the related art, in which the waste is ground into particles and then directly subjected to magnetic separation treatment, the technical solution of the utility model can first prepare the waste particles into a slurry mixture by the slurry treatment device 20, so that the slurry mixture is ultrasonically treated by the ultrasonic treatment device 30, so that the particles with greater adhesion in the slurry mixture can be weakened and separated, so that the difficulty of magnetic separation of waste particles can be reduced, thereby reducing the magnetic field strength and processing time required by the magnetic separation device 40, thereby reducing the energy consumption of the magnetic separation device 40 and improving the magnetic separation efficiency of the waste treatment equipment 100.

[0043] In addition, in the related art, the magnetic separation device 40 is very sensitive to the particle size, and the treatment effect is greatly affected by the particle size. Therefore, the technical solution of the utility model can use ultrasonic pretreatment to achieve effective waste treatment in a wider range of particle sizes by grinding solid waste, preparing slurry mixture, and performing ultrasonic treatment in sequence, thereby facilitating the improvement of the particle size adaptability of the waste treatment device 100.

[0044] Please refer to Figure 1 In some embodiments of the utility model waste treatment equipment 100, the ultrasonic treatment device 30 includes:

[0046] An ultrasonic processor is disposed in the ultrasonic processing tank and is used for ultrasonically processing the slurry mixture in the ultrasonic processing tank.

[0047] In this embodiment, the ultrasonic processing device 30 includes an ultrasonic processing tank and an ultrasonic processor. The ultrasonic processor can utilize the cavitation effect of ultrasonic waves in the liquid medium to form sound wave pressure and thermal effects, thereby achieving the effect of uniform stirring, crushing and grinding, thereby achieving the weakening and separation of the adhered particles in the slurry mixture.

[0048] Optionally, the ultrasonic treatment device 30 of the utility model is suitable for treating a slurry mixture containing magnetic mineral particles and coal particles, wherein the ultrasonic frequency range can be set to 20kHz to 40kHz, and the intensity range can be set to 0.5W / cm 2 ~10W / cm 2 , the duration ranges from a few minutes to about an hour. In this way, it can not only meet the relatively ideal waste particle weakening and separation effect, but also avoid excessive damage to the inorganic mineral phase in the slurry mixture due to the ultrasonic frequency, intensity and duration being too long. Of course, the parameter range of the ultrasonic treatment device 30 of the utility model can also be set according to actual factors such as the type of waste material actually used, and is not limited here.

The second stirring mechanism 21 in the solid-liquid mixing chamber can stir the waste particles and the liquid in the solid-liquid mixing chamber so that the two are evenly mixed to form a slurry mixture, so that the ultrasonic treatment device 30 can use the cavitation effect of ultrasonic waves in the liquid medium to achieve the weakening and separation of the waste particles.
