Description
Electrothermal blowing drying device Technical Field The invention relates to the technical field of object drying, in particular to an electrothermal blowing drying device. Background The electrothermal blowing drying box is a drying device with wide application, and is commonly used in the industries of chemical industry, food, medicine, electronics, materials and the like for the processes of dehydration, drying, solidification, shaping and the like of materials. The basic working principle is that the electric heating element generates heat, the air blowing device sends hot air into the box body to be fully contacted with the material to be dried, and the water in the material is taken away through heat exchange, so that the drying is realized. In the car coupler overhaul flow, the device is mainly used for preheating before repair welding, quick drying after cleaning and dehumidifying and rust-preventing treatment, and is a key device for guaranteeing overhaul quality and stabilizing subsequent procedures. However, in practical use, the following problems still remain: Firstly, if untreated hard water (such as tap water or underground water) is used for cleaning, calcium ions and magnesium ions contained in the water can be separated out and attached to the surface of a coupler in the high-temperature drying process, so that scale is formed. If magnetic powder or ultrasonic flaw detection is directly performed after drying, a scale layer may cover micro cracks or influence the coupling effect of a flaw detector, so that inaccurate detection is caused. Because hard water is positioned at each part of the coupler, the coupler is required to be comprehensively wiped after being dried, and the wiping time is long. Secondly, when the coupler surface remains more moisture, only the drying time is required to thoroughly dry, and the overall maintenance efficiency is affected. Disclosure of Invention The invention aims to provide an electrothermal blowing drying device which is used for removing water from articles before drying by controlling the pressure and the flow rate of air outlet and isolating the removed water through a liquid collecting cavity, so that the problems in the prior art are solved, namely the problems of long wiping time and long drying time caused by more scales on the surface of a coupler. In order to achieve the purpose, the electrothermal blowing drying device comprises a shell, an inner container, an air adjusting component, a separation piece and a heating pipe, wherein the guide plate, the fan blades and the heating pipe are arranged in the inner container; The air adjusting component is rotationally arranged on the side wall of the guide plate and is provided with a first air outlet for drying the article and a second air outlet for increasing the air flow rate, and the first air outlet and the second air outlet move to the front of the fan blade in a rotating mode; the isolation piece separates the inner bag bottom into the liquid collecting cavity, the liquid collecting cavity is used for receiving the moisture that article surface falls, and during the drying operation, the isolation piece separates liquid collecting cavity and inner bag inside, makes the unable dry operation of participating in of moisture in the liquid collecting cavity. According to the technical scheme, the wind power is increased before drying, most of water can be directly blown down after the wind power is increased, and then the water directly enters the liquid collecting cavity for isolation storage. Therefore, when the car coupler is dried, the residual moisture on the surface of the car coupler is less, the scale formed at the moment is reduced, and the blown water is not heated, so that the car coupler can be heated up quickly. Compared with the prior art, the invention has the beneficial effects that: 1. In the electrothermal blowing drying device, the air flow pressure and the air flow speed are regulated by arranging two air outlets, and before drying, the hard water on the surface of an article is blown down by utilizing high-flow-rate gas generated by the second air outlet, and the blown hard water is isolated by matching with the liquid collecting cavity. In the drying process, hard water on the surface of the article is reduced, so that the generation of scale is reduced, the area required to be wiped is reduced, and blown hard water is stored in the liquid collecting cavity and cannot be heated, so that heat in the inner container acts on the article, the heating speed in the inner container is increased, and the drying time is reduced. 2. In this electric heat blast drying device, the liquid collecting cavity not only collects the water that blows off when dewatering through the air current, can also set up the replacement heat pipe and cool down the gas in the inner bag. Through pouring enough cold water into the liquid collecting cavity in advance, after the drying is finished, the heat e
