Technical Field
[0001] The utility model belongs to the technical field of fumigation treatment devices, and in particular relates to a movable fumigation and medication vaporization device. Background Art
[0002] Methyl bromide, also known as methyl bromide, has good diffusivity and penetrability, and is highly toxic to insects and nematodes. It is often used as an insecticide, fungicide, and fumigant, especially in the field of pest control of wood, wood products, and wood packaging materials. Methyl bromide fumigant can be used to thoroughly and effectively kill boring pests in wood, wood products, and wood packaging materials.
[0003] At present, when using existing methyl bromide fumigation equipment to fumigate items placed in a warehouse, the items to be fumigated are generally placed directly in the fumigation warehouse, and then methyl bromide gas is injected into the warehouse through a dosing vaporization device for fumigation to remove harmful substances attached to the items and prevent the harmful substances from spreading along with the items.
[0004] However, the existing methyl bromide dosing and vaporization device has certain defects in the actual application process: since methyl bromide has the characteristics of low boiling point (3.56℃) and large absorption latent heat under normal conditions, and methyl bromide is generally processed into bottled liquefied gas for use at various ports, during the application process, it is necessary to rely on the pressure in the steel cylinder to output a certain amount of liquid methyl bromide from the pipeline port, and transport the liquid methyl bromide to the fumigation space through the application tube and quickly vaporize it to fill the fumigation space, thereby achieving the purpose of fumigation treatment; therefore, when the liquid methyl bromide is released from the steel cylinder, it will absorb heat and vaporize, thereby reducing the temperature of the surrounding environment, and causing the methyl bromide to be easily incompletely vaporized during the subsequent vaporization process, thereby affecting the fumigation quality. Utility Model Content

[0009] Furthermore, a visual liquid level observation window is provided on the side wall of the heating box, and the visual liquid level observation window allows the staff to conveniently observe the liquid level of the heat transfer oil in the heating box to avoid dry burning faults and the like.
[0010] Furthermore, the purge assembly includes a gas pipeline, the gas outlet of the gas pipeline is connected to the corresponding joint on the three-way joint, the gas inlet of the gas pipeline is connected to the air pump and the safety gas source in sequence, and a purge control valve is arranged in the middle of the gas pipeline.
