DETAILED DESCRIPTION

[0066] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0067] A specific embodiment of the present invention discloses a coal gangue modification and activation device, the structural schematic diagram of which is shown in FIG. Figure 1 As shown, it mainly includes a tilted box body 11. For example, the tilt angle formed between the box body 11 and the horizontal ground is 35°-85°, so that the automatic loading of coal gangue and the automatic discharging under the action of gravity can be realized. The box body 11 is fixed to the ground through the front support 17 and the rear support 23. The upper ends of the front support 17 and the rear support 23 are fixedly connected to the box body 11 through the box body base 21, and the lower ends are fixedly connected to the ground through the ground angle bolts 18. In this embodiment, the inner layer 16 of the box body 11 is composed of 304 stainless steel plate, the middle layer 15 is composed of alumina fiber, and the outer layer 14 is composed of metal material. Other suitable materials can also be used. The box body 11 can be processed into a cuboid, a cube, a cylinder, a polyhedron, a truncated cone, etc., which is not specifically limited here.

[0068] The box 11 is provided with a pressure safety valve 7, an air compressor 25 (illustratively, such as a micro air compressor) and a microwave generator 10. A microwave uniformly distributed diffusion tube 12 (which can be called a microwave uniformly distributed diffusion tube) is provided in the box 11. The diffusion tube 12 is installed inside the box 11 through a support 26, and the microwave uniformly distributed diffusion tube 12 is connected to the air compressor 25 installed in the middle. The microwave uniformly distributed diffusion tube 12 is provided with a microwave leakage prevention net at both the air inlet and the air outlet to ensure the safety of the device. The diameter direction of the microwave uniformly distributed diffusion tube 12 is arranged to have tangential air distribution holes, and the hole distribution rate accounts for 50%-80%. The box 11 is connected to the diffusion tube 12 by an air compressor as a wind source. Under the action of wind, a rotating wind field is automatically formed inside the box 11 to enhance the energy flow density of microwaves, further accelerate the uniformity and intensity of microwave action on coal gangue, improve the penetration ability of microwaves on coal gangue, and increase the vibration, friction and heat generation of molecules inside and outside the coal gangue to meet the purpose of rapid temperature increase, thereby expanding the processing capacity, removing water vapor and other gases formed in the material heating process in real time, reducing the pressure on the box caused by the gas generated in the heating process, and ensuring the industrial production of coal gangue activation.

[0069] Considering that the bottom of the box 11 is easy to deposit materials, and during the heating process, some materials in the materials are easy to liquefy, and the liquefied materials will gather at the top of the box. Therefore, in actual operation, waveguides are relatively arranged on both sides of the box 11. The waveguides are preferably spiral. Therefore, the waveguide arranged on the front side of the box is called the front spiral waveguide 19, and the waveguide arranged on the rear side of the box is called the rear spiral waveguide 22. The front and rear spiral waveguides are connected to the microwave generator 10 to form a rotating microwave field to ensure the vertical effect of microwaves on the materials; and to minimize the microwave power consumed by the processed materials to enhance the heating capacity of microwaves on coal gangue and improve work efficiency. The material of the spiral waveguide, the shape, direction, size, position, etc. of the opening can be selected according to actual production needs, and no specific limitation is made here.

[0070] Spacing hollow protective plates 20 are provided on the upper and lower sides of the microwave uniform diffusion tube 12 and between the microwave uniform diffusion tube 12 and the waveguide, with a porosity of about 85%. The microwave uniform diffusion tube 12 and the spacing hollow protective plates 20 are parallel to the bottom surface of the box; the spacing hollow protective plates 20 can ensure a reasonable action distance (3cm-5cm) between the material and the waveguide, and create a good conduction environment between the microwave and the material in the microwave field.

[0071] Preferably, the box body 11 is further provided with a pressure safety valve 7, which is used to automatically open and release the pressure when the internal pressure of the box body 11 reaches a limited value, so as to ensure the stability of the interior of the box body.

[0072] Preferably, the above-mentioned device can also include an upper gangue belt 13, a quenching treatment device (including an activated gangue funnel 2 and a water spray quenching device 3), and a lower conveying belt 1.
