Embodiment Construction

[0016] Embodiments of the present invention are further described below in conjunction with accompanying drawings:

[0017] Such as figure 1 , 2 As shown, the vertical microwave drying coal furnace includes a microwave drying furnace body 1, a feeding hopper 8 is arranged on the top of the microwave drying furnace body 1, a waveguide 7 for conducting microwaves is installed on the microwave drying furnace body 1, and the microwave drying furnace body In 1, a vertical feeding screw 2 and a ventilation pipeline 6 are installed. The air inlet 5 of the ventilation pipeline 6 is connected to the high-pressure nitrogen filling equipment, and the exhaust port 9 communicates with the outside world. The ventilation pipeline 6 is drilled and microwave drying oven A discharge valve 3 is arranged at the discharge port at the bottom of the body 1, and a screw conveyor 4 is installed below the discharge port.

[0018] When working, the conveying device (such as a belt conveyor) transports...

Abstract

The invention belongs to the field of material drying equipment, in particular relates to a vertical microwave drying coal furnace which comprises a microwave drying furnace body, wherein a feeding hopper is arranged at the top end of the microwave drying furnace body; a waveguide duct for conducting microwaves is installed on the microwave drying furnace body; a ventilation pipeline is arranged in the microwave drying furnace body; a gas inlet of the ventilation pipeline is connected with high-pressure nitrogen gas filling equipment, and a gas outlet of the ventilation pipeline is communicated to the outside; the ventilation pipeline is drilled; and a discharge valve is arranged at a discharge opening at the bottom of the microwave drying furnace body. In the invention, a vertical structure is adopted, thus the floor space is small, the structure is simple, and the manufacturing cost is lowered; the microwave heating is adopted, thus the coal can be dried quickly and uniformly; the coal is used as a heating element, thus the heat utilization efficiency is high, the energy is saved, and the environment is protected; the high-pressure nitrogen gas filled in the ventilation pipeline forms negative pressure in the pipeline, and a through hole only absorbs water vapor evaporated from the coal, thus the clogging or microwave leakage is avoided; and a helical conveyer below the discharge opening can be used for accurately controlling the discharge quantity and discharge speed of the coal.

Description

technical field [0001] The invention relates to a vertical microwave oven for drying coal, which belongs to the field of material drying equipment. Background technique [0002] At present, traditional drying methods such as flame, hot air, steam, and electric heating are usually used in material drying equipment. These traditional methods are all external heating and drying. After the surface of the material absorbs heat, the heat penetrates into the material through heat conduction and then heats up. Drying, but it takes a certain amount of time for the center of the material to reach the required temperature, and objects with poor thermal conductivity take longer and the heating is uneven. At present, some enterprises adopt the method of microwave drying. Compared with the traditional drying method, the drying mechanism of microwave drying is different. Microwave can penetrate the inside of the object and heat the inside and outside at the same time. The heating is fast a...
