Multi-function blowtorch and how to use it

Abstract

The invention discloses a multifunctional blow lamp and an application method. The multifunctional blow lamp is characterized in that a fuel storage tank and a flame tool are located on the two sides of an air supply device, and the fuel storage tank, the flame tool and the air supply device are fixed to a supporting keel and connected through an air supply pipeline; a flame gun assembly of the flame tool is installed at the upper end of a lifting assembly, a horizontal rotating assembly is indirectly connected with flame guns through lifting, a horizontal linear movement assembly is indirectly connected with the flame guns, the flame guns ascend and descend through the lifting assembly, and the flame guns reversely move on an operation table panel; a liquid fuel injection port and a fuel gas inlet pipe are arranged at an upper cone of the fuel storage tank, a gas head is arranged in a lower cone, and an emptying valve is arranged outside the lower cone; and according to a circuit, a series circuit composed of an air pump motor switch, a motor and a speed adjustor is connected with a series circuit composed of a heat source box resistor switch, a heat source box resistor and a thermosistor in parallel and then connected with a shutdown switch in series to be connected to a main power source. When fuel needs to be added, an overturning plate is pulled, and power supply is turned off. The multifunctional blow lamp and the application method are used for experiment teaching, machining and repairing industries, the experiment operation efficiency is improved, personal safety is guaranteed, and the fire risk is reduced.

Description

technical field [0001] The invention belongs to chemical experiment teaching aids, research tools and processing tools, and relates to a multifunctional mechanical facility integrating chemical experiment application type and processing tools, a multifunctional blowtorch and a using method. Background technique [0002] Alcohol blowtorches are commonly used heat sources in chemical experiments. It is mainly used for experimental materials that require enhanced heat, partial processing of glassware, etc. In the teaching of inorganic chemistry experiments, for the production course of non-standard glassware, it is necessary to use a blowtorch to heat the glass used for processing and preparation to produce the required devices. Commonly used alcohol torches include seat alcohol torches and hanging alcohol torches. The alcohol of the seat type alcohol blowtorch is stored in the lamp holder, and the alcohol storage tank of the hanging type blowtorch is suspended on a high plac...

AI Technical Summary

Problems solved by technology

Inject alcohol into the alcohol storage tank to 2 / 5 to 2 / 3 of the total capacity of the lamp pot. Because the blowtorch body has no metering accessories, the injection of alcohol will be overfilled, which may cause danger

The traditional blowtorch obtains a high-temperature flame by mixing alcohol vapor with air and burning it. The high-temperature airflow will make the blowtorch make a sharp whistling sound. Especially in the experimental teaching practice class, dozens of people use the blowtorch at the same time, and the noise is very loud. Make the students who are new to utensil processing feel afraid and dare not operate, which affects the teaching effect
